Operation method of the staples used in surgery: An intestinal anastomosis is used to illustrate the use of the stapler. The anastomosis is sutured in the proximal intestine, placed in the staple holder and tightened. The stapler is inserted from the distal end, the central piercer of the stapler is threaded out and articulated with the central rod of the proximal stapler against the staple holder, and rotated close to the distal and proximal bowel walls. Adjust the distance between the staple holder and the base according to the thickness of the intestinal wall, generally by turning the hand tighter (with a tightness indicator pin on the handle).

Squeeze the closing anastomosis wrench to tighten the anastomosis, and the sound of the sound indicates that the cutting anastomosis is complete. Do not withdraw the anastomosis and check to see if the anastomosis is satisfactory and if other tissues, such as the mesentery, are embedded. After being dealt with accordingly, the anastomosis was unscrewed and gently pulled from the distal end to check for the integrity of the distal and proximal bowel resection rings.

Precautions for use of the stapler

(1) Before the operation, check whether the ruler and 0 scales are aligned, whether the assembly is correct, and whether the push-piece and tantalum nail are missing. A plastic washer should be installed in the resistor.

(2) The broken end of the intestine to be anastomosed should be fully free and stripped at least 2cm.

(3) The distance between the stitches of the purse suture should not exceed 0.5cm, and the margin should be 2~3mm so that too much tissue is easy to embed in the anastomosis and hinder the anastomosis. Be careful not to omit the mucosa.

(4) Adjust the spacing according to the thickness of the intestinal wall, with 1 to 2 cm being appropriate.

(5) Check the stomach, esophagus, and other adjacent tissues before hitting to prevent clamping into the anastomosis.

(6) The cut should be made quickly, and pressure should be applied at the end to make the staple into a "B" shape.

(7) Exit the surgical stapler gently and check whether the incised tissue is a complete ring.

The Principles of parting line plastic injection molding Design

1. The part with coaxiality requirement should be formed on the core side. If it is formed in the cavity and core side, it will be difficult to ensure the coaxiality due to the inaccurate clamping.

2. When selecting the parting surface, the dimension difference between the ends of the plastic part due to the draft angle should be reduced. The parting surface should be selected as much as possible without affecting the appearance of the plastic part and is able to meet the requirement of appearance. The split line and miss-match shall be submitted to the customer for confirmation;

3. The distance between the plates: the determination of the parting line should ensure that the mould cavity and core opening strokes are the shortest;

4. Should avoid the core pulling mechanism as much as possible, if it is impossible to avoid the core pulling, the pulling distance should be as short as possible, and try to make the slider all in core side;

5. Since the locking force is small when the inclined slider is closed, for a large plastic part with a large projection area, the parting line of the large projection area can be placed on the main plane after the cavity and core clamped, and the smaller projected area as the lateral parting surface, otherwise the locking mechanism of the inclined slider must be very large, otherwise, the burr is occurred due to non-tight lock.

6. The determination of the parting surface does not affect the normal opening of the injection gate system, especially the two plate mold with the multi-cavity parting surface.

7. In order to help the venting of the mold, the parting surface is as close as possible to the end of the plastic material stream.

8. The overall structure of the injection mould should be simplified, the number of parting line in mouldis minimized, and a straight parting line is used as much as possible. Should also consider whether the mold is easy to machining and process, easy to take out the finished plastic part, the parting surface should be selected as much as possible on the ridge of the plastic part.

9. Convenient installation of metal inserts.

10. Keep the product in the core side as much as possible and make sure there is enough position.

11. Sharp corners should be avoided in the parting line, as sharp corners will affect the life of the plastic injection mould. Therefore, parting line in plastic designshould check very carefully. If it cannot be avoided, send a proposal to the customer whether the product can be modified.

At present, there are three kinds of projection technology: CRT, LCD, and DLP.

CRT projector is the earliest projection technology, which is similar to the CRT display. It has the advantages of long life, rich color display, good reducibility, and rich ability to adjust geometric distortion. Due to technical constraints, it is impossible to improve the resolution and lumen at the same time. Therefore, CRT projectors have been phased out at this stage.

The technology of LCD projector is transmission projection technology, which is the most mature at present. The color of the projection screen is restored to be true and bright. With high color saturation and high light utilization efficiency, an LCD projector has a higher brightness output. At present, the LCD projector is the main projector with a high lumen in the market. Its disadvantage is that the black layer is not very good. LCD projection technology is divided into LCD and 3LCD. The difference between them lies in the color restoration degree and picture quality.

DLP reflective projection technology. The gray level and signal-noise ratio of DLP projector image are greatly improved, and the image quality is fine and stable. In particular, when playing dynamic video, the image is more smooth, without pixel structure sense, the image is natural, and the digital image restoration is true and accurate. The advantage of DLP compared with 3lcd is that there is no crosstalk between grayscale and 3D.

Of course, there is also LCOS projection technology, which is a new projection technology. Because the cost is too high, it is seldom used

Projector contrast

Contrast is the ratio of black to white, that is, the gradient level from black to white. The larger the ratio, the more gradients from black to white, and the richer the color representation. Contrast is very important to the visual effect. Generally speaking, the larger the contrast is the clearer the image is, and the brighter the color is. However, if the contrast is small, the whole picture will be gray. High contrast is very helpful for the clarity, detail, and gray level of the image. High contrast has advantages in black-and-white contrast, clarity, integrity, and so on. Relatively speaking, in the aspect of the color level, the influence of high contrast on an image is not obvious. The contrast has a greater impact on the dynamic video display effect. Because of the fast conversion of light and dark in the dynamic image, the higher the contrast, the easier it is for the human eyes to distinguish such a conversion process. The products with high contrast have more obvious advantages in detail performance, clarity, and high-speed moving objects performance in some dark scenes.

Projector brightness

The brightness of the projector is usually expressed by light out, which describes the ability of light source radiation to produce a visual response in unit time, and its unit is the lumen. There are two methods to measure brightness. 1. The average brightness of 9 intersections of "Tian" is multiplied by the length and width of projection. Test precondition projection distance is 2.4m; the projection size is 60 inches. 2. All black and all white contrast method. Select a black-and-white contrast image, measure, and calculate the black-and-white brightness difference times the projected area. When choosing the projector to determine the brightness index, we should not only consider the size of the used space but also consider the influence of the use of environment brightness. And the brightness selection should leave a margin, and the brightness will decrease after a period of use due to the influence of the bulb. It is recommended to choose 800-2000 lumens for the brightness of the home projector, 2000-4500 lumens for a small conference room or standard classroom, 3500-5000 lumens for medium conference room, and ladder classroom, and 5000 lumens for large conference room or auditorium. Of course, this is only a reference value. The accurate brightness should be calculated according to the actual ambient brightness and the size of the screen. For example, taking the classroom as an example, the average brightness is 500lux, and the formula is projector brightness = ambient brightness * 2 (Times) × screen length * screen width * 1.2 (loss coefficient) ≈ 3300. Therefore, it is necessary to fully consider the use environment and cost performance to select the appropriate brightness index.

Projector lens

Zoom ratio: the ratio of the maximum focal length to the minimum focal length, that is, the zoom ratio of the projection picture under a certain projection distance. This parameter does not affect the projection distance, etc.

Projection ratio: projection distance / screen width.

Lens focal length: distance from LCD panel to lens, unit: mm

Projection distance: distance from lens to screen, unit: mm

Panel size: LCD size in inches

Screen width: the effective width of the screen, in inches. It should be noted that the aspect ratio should be the same as that of the panel.

Calculate the projection distance according to the projector: projection distance = screen width * lens focal length/panel size

Projection distance = screen width (mm) × projection ratio

Calculate the appropriate projector according to the site conditions: lens focal length = projection distance * panel size/screen width

Precautions for projector installation:

1. Accurately calculate the projection distance, which is the distance between the lens and the screen; align the projector lens with the left and right center of the screen as much as possible; calculate the installation height of the projector according to the difference between the lens and the screen height (refer to the projector manual). Special attention shall be paid to this item when using a fixed focus projector, so as to avoid that the image cannot be full screen or over the screen. In case of slight error, fine adjustment can be made through the relative position between the projector and hanger.

2. During construction, pay attention to load-bearing reinforcement for the installation position of the projector and curtain according to the actual situation on site.

3. Try to select the projector hanger with excellent quality. The poor hanger is not perpendicular to the roof, and the installation screws cannot be tightened. Such problems affect construction efficiency.

4. If the electric screen is selected, a strong electric socket shall be reserved in the screen box, and the electric screen shall be equipped with remote control as far as possible to avoid affecting the appearance.

5. Do not power off the projector immediately after debugging. After the bulb cools and the fan stops rotating, cut off the power.

6. For projector cable, VGA, HDMI, and other cables can be reserved according to specific requirements, and network cable can be reserved according to specific functions of the projector.

(5) Store curves and load scanning software

Sometimes, in order to get the best color and scanning contrast, take a low-resolution scan first, open it in Photoshop then, and use Photoshop's curve function to improve color and contrast. Save the curve and load it back into the scanning software. The scanner will now use this color correction curve to create a better high-resolution file. If several images are scanned with a similar gamut range, the same curves can be used, and curves can also be stored frequently and loaded back as needed.

(6) Place the scanned object according to the required effect

In the actual process of using images, it is sometimes hoped that images with oblique effects can be obtained. Many designers often input images into computers through scanners, and then use professional image software to rotate the images to achieve the rotation effect. However, this process is very time-consuming, and the image quality will decline according to the angle of rotation. If you know in advance how the image is placed on the page, then using the protractor and the bottom edge of the original to place the original at a precise angle on the cylinder and the platen, you will get the highest quality image without rotating in the image processing software.

(7) Find the best scanning area on the glass plate

In order to obtain the best image scanning quality, find the best scanning area of the scanner, and then place the object to be scanned here to obtain the best and most fidelity image effect. The specific searching steps are as follows: first, set all controls of the scanner to automatic or silent state, select all areas, and then scan a blank, white or opaque sample with low resolution; then use Photoshop, a professional image processing software, to open the sample manuscript. Use the averaging command (Equalize menu item) in the software to process the sample manuscript. After processing, you can see where there are cracks, stripes and black spots on the scanner. You can print this document and cut out the best area (that is, the most stable area) to help place the image.

(8) Use transparent sheet fittings to obtain the best scanning effect

Many flatbed scanners are equipped with transparency fittings placed at the top of the scanner bed. In order to obtain the best scanning of transparent films or slides, remove the pictures from the rack and slide mounting rack and mount them on the glass scanning bed with the reverse side facing down (the reverse side is usually a rough surface). Cut out the mask with black paper and cover the entire scanning bed except where the manuscript is set. This will reduce glare and overexposure during scanning. Similarly, when scanning a three-dimensional object, cover the cover of the scanner with an object with a strong contrast in color with the object you are scanning. This will help you to select it more easily with the PhotoshopColorRange tool.

X3 document camera scanner

(9) Maximize that color gamut of the scanned image

In order to make full use of the 30-bit or 36-bit scanner to increase the color range, the scanner software (such as FotoTune of Agfa) or other company's software should be used to adjust the color as much as possible. Because Photoshop software is limited to 24-bit images, images may be inserted in the widest color gamut range.

(10) Scan printed matter with no screen printing technology

When scanning printed matter, there will be screen flowers in the continuous tone of the image. If the scanner does not have a screen removal function, try to find the resolution that minimizes the screen size. Often, the same or double resolution of the screen line of printed matter may work. Once you get a fairly good scan, use Photoshop as a Gaussian Blur filter (with a setting of less than 1 pixel) to slightly soften the mesh until you cannot see it. Then use Unsharp Mask to sharpen the image back. Scanning can also be improved by slightly rotating the image because the continuously adjusted screen angle is changed. For black-and-white images, the rotation of 45 degrees is just right. For CMYK images, experiments will be required.

Here are some tips for learning mandarin

Tip 1. Find out the corresponding rules in Mandarin and their dialects, and enhance the memory.
The difference between various dialects and Mandarin Chinese language is mainly phonetics, with little difference in vocabulary and grammar. The main differences in phonetics are as follows: in most areas blade-alveolars are used the same as retroflex; so do n and l; many vowels like eng、ing、e、uo are ignored; the rounded lips of vowels for most people are not enough. Combining these characteristics, students can find the corresponding rules of dialects and Putonghua, and thus practice and memorize the difficulties.

Tip 2. Try to achieve a full breath and clear pronunciations.
That is to say, read the consonant, vowel and tone of every character loudly, in particular, the vowel. Don't be vague. The vowel head, body and tail should be read clearly. For example, the pronunciation of xiang(响) should be “x-i-ǎ-ng”(consonant-vowel head-body-tail) rather than “x--ng ”(consonant-vowel head-tail).

Tip 3 .Pay attention to the pronunciation of the neutral-tone words.
In addition to the required words, many function words also read softly, such as structure auxiliary(de的, de地, de得), dynamic auxiliary(zhe着, le了, guo过) , directional verb(lai来, qu去) and plurality(men们).

Tip 4. When reading an article, be sure to express the emotion of the article correctly.
Pay attention to the stop, stress, tone and rhythm. In a word, where should we stop and how long; where is the stress and where should be light; which sentences should be connected in one paragraph and which not and which is the key point; is the voice of the whole sentence ascending or descending, strong or weak, quick or slow? All of these should be relished and practiced a lot.
