The surgical stapler includes the shell, the center rod, and the push tube. A center rod is set in the push tube. On the front end of the center, the rod is equipped with a nail cover. The rear end is connected to the adjusting knob at the rear of the shell through the screw, and on the surface of the shell is equipped with a triggering handle. The triggering handle is movably connected to the shell through a hinge. The main working principle of the surgical stapler is to use titanium nails to disconnect or anastomose the tissue, which is similar to a stapler.

The surgical stapler is characterized in that: a link mechanism is arranged in surgery instruments, three connecting rods are respectively connected with the triggering handle, the inner wall of the casing and the push tube, and the end of the three connecting rods are connected to the same living hinge. The three-link mechanisms of the connecting rod include the power rod, the support rod, and the sports rod; the power rod and the triggering handle are hinged and the support rod and the housing are connected by a living hinge; the sports rod and the push tube are connected by a living hinge. The practical and new-model stapler has advantages like simple structure, convenient operation, and strong stability. The connecting structure of the ring knife and the push rod of the digestive tract stapler includes the pushrod and a ring knife fixedly connected with the pushrod. On the outside of the ring knife stated above, are set with the pad cutter rings arranged in the circumferential direction. The end of the ring knife is embedded in the pushrod. Because the end of the ring knife is embedded on the push rod, the concentricity of the ring knife and the push rod is high. When it is cutting the tissue, the ring knife can sit smoothly in the middle, so that the surgical success rate will be high.

Stapler is the second category, and stapler nails are the third category of instruments. Divided by type: reusable and single-use Esophageal and intestinal stapler are abdominal surgical instruments, vascular stapler is thoracic cardiovascular surgical instruments, titanium nails are non-toxic, histo-compatible, non-exclusionary chemically stable high strength, tensile resistance, soft and tough.

The surgical linear stapler allows the tissue to be sutured in a straight line. The tissues are placed between the staple magazine and the staple drill, a positioning needle is placed, the thickness of the tissues is predetermined according to the thickness of the tissues, the firing handle is triggered, the staple driver inserts two rows of staples into the tissues and bends them into a "B" shape, before releasing the sutures, the excess tissues and the organs expected to be removed must be removed along the edge of the sutures' osprey mouth, and the broken ends are disinfected with iodine, then the sutures are released and removed. Although, the straight-line Stapler only one function, but more widely used, mainly for the bronchial tube, esophagus, stomach, duodenum, intestine, blood vessels, and other stump closure.

Surgical skin stapler: It can suture longer skin incisions with easy operation, high speed, light tissue reaction, and beautiful healing. The skin stapler is used for long sutures in general surgery, orthopedics, obstetrics and gynecology, burns, emergency medicine, cardiothoracic surgery, neurosurgery, and other surgical departments. The wounds are sutured with epidermal sutures or skin grafts. Island stapling has the advantage of being quick and easy, and all skin incisions are grade A healed.

Currently, the surgical stapler suture used in clinical practice is fast, easy to operate and has no rejection reaction to the tissue. They improve tissue receptivity to staples with fewer side effects, effectively reducing patient pain and increasing surgeon efficiency and surgical success. Due to these advantages, now, the stapler is widely used in a variety of surgical procedures.

With the increase in the number of surgical procedures, the widespread use of minimally invasive surgery, and the gradual improvement of medical infrastructure, the global medical and surgical instruments market is growing at a rapid rate. The market shows a steady growth trend. With the continuous growth of China's economic strength, the medical level of the population and the deepening of medical reform, the ability of China's residents to pay for medical services is also increasing. Currently, there is a clear trend toward an aging population in the country and beyond, and against the backdrop of an increasing number of people suffering from cardiovascular and cerebrovascular disease, cancer and diabetes, the use of stapler among surgeons and patients at home and abroad continues to grow at a rate higher than the global average.

Before performing the anastomosis, the ends should be aligned to prevent one or both sides from twisting; release the sides while ensuring good blood supply to the anastomosis and ensuring that the anastomosis is tension-free.

Place your left hand around the anastomosis to protect it from foreign body entrapment. It is important not to be too loose, nor too tight. As too loose can prevent the two walls from fitting closely, which may result in the poor anastomosis, postoperative bleeding, and anastomotic fistula; too tight may result in extrusion injury to the gastrointestinal tract, causing postoperative scarring, resulting in narrowing of the anastomosis or difficulty in withdrawing the anastomosis, and in severe cases may result in tearing of the anastomosis.

The anastomosis should be performed quickly and accurately, in one single movement, to ensure that the surgical stapler does not swing left, right, up and down, so as not to aggravate the tissue damage around the anastomosis or increase the possibility of anastomotic fistula or stenosis.

The cause of the unsuccessful anastomosis should be identified immediately and an instrumental or manual anastomosis should be performed again.

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.
