Problems solved by technology

[0004] Traditional staplers cannot temporarily and quickly change the angle of the end of the stapler during the operation on the internal tissues of the human body. Therefore, the doctor needs to adjust the direction of the stapler outside the human body. In this way, the operation of adjusting the angle is very inconvenient, and the instrument The main body will be dragged and moved, which will seriously damage other tissues in the human body; in addition, during the operation of the traditional stapler, the internal staples will fall off accidentally, which has many surgical risks

Embodiment 1

[0037] see Figure 1-2 as well as Figure 5 , a surgical linear cutting stapler, comprising a control handle 1, a rotator body 2, an adapter assembly 3 and an apparatus head assembly 4;

[0038] refer to figure 1 The rotator body 2 is rotated and assembled on one end of the control handle 1, and the adapter assembly 3 is rotatably assembled on the other end of the rotator body 2 away from the control handle 1. The body 2 also includes a main body 201, and the head assembly 4 also includes a head pipe 401. The inner part of the main body 201 and the head pipe 401 close to each other is assembled with a spacer 6, and the other end of the head pipe 401 is fixed. A staple cartridge case 402 is provided, the other end of the staple cartridge case 402 is rotated and assembled with a nail plate 403, the staple cartridge case 402 fits with the nail plate 403, and the nail cartridge case 402 is movably assembled with a movable nail cartridge 5.

[0039] refer to figure 1, the contr...

Embodiment 2

[0045] see Figure 3-4 , a surgical linear cutting stapler, comprising a control handle 1, a rotator body 2, an adapter assembly 3 and an apparatus head assembly 4;

[0046] refer to image 3 and Figure 4 The spacer 6 also includes an end plate 602, and both ends of one side of the end plate 602 are fixedly welded with an inner arc plate 601, and four sets of inner arc plates 601 are respectively symmetrically inserted into the main body 201 and the inside of the head pipe 401, During the rotation of the head tube 401, the end plate 602 will be squeezed from the transfer tube 301, the inner wall of the main body 201 and the head tube 401 is fixedly provided with an inner stopper 604, and the other end of the inner arc plate 601 is fixed. A spring 603 connected to the inner block 604 is fixedly connected, and the inner arc plate 601 will move inside the main device body 201 or the head tube 401, and at the same time cooperate with the inner block 604 to squeeze the spring 60...

Embodiment 3

[0049] see Figure 6-7 , a surgical linear cutting stapler, comprising a control handle 1, a rotator body 2, an adapter assembly 3 and an apparatus head assembly 4;

[0050] refer to Figure 6 , the movable staple bin 5 also includes a staple case 501, the middle of the staple case 501 is fixed with a blade groove 503 inside, and the inside of the staple case 501 is located on both sides of the blade groove 503 and is equidistantly provided with nail grooves 502, and the nails in different vertical rows The grooves 502 are arranged in steps, and the length and dimension of the staples located on the outside gradually increase. Cooperating with the nail grooves 502 arranged in steps, the thickness of the suture can be gradually increased from the center of the suture to both sides, thereby avoiding damage caused by the pulling between tissues. A phenomenon that causes the edge of a seam to crack.

[0051] refer to Figure 7 , the inner walls of the nail grooves 502 are fixed...

Abstract

The invention discloses a surgical linear cutting anastomat, and belongs to the field of medical instruments. The surgical linear cutting anastomat comprises a control handle, a rotating device body, an adapter assembly and a device head assembly, the rotating device body is rotatably assembled at one end of the control handle, and the adapter assembly is rotatably assembled at the other end, away from the control handle, of the rotating device body; the rotating device body is rotationally connected with the device head assembly through the adapter assembly, the partition devices are assembled in the ends, close to each other, of the main device body and a device head pipe, a nail bin shell is fixedly arranged at the other end of the device head pipe, a nail plate is rotationally assembled at the other end of the nail bin shell, a movable nail bin is movably assembled in the nail bin shell, the angle of the device head pipe can be flexibly changed regardless of places, the rotating process is more flexible, other tissues clamped in the body can be avoided, and in addition, the surgical risk that suturing nails fall off is reduced while the good suturing effect is guaranteed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a surgical linear cutting stapler. Background technique [0002] The stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery; it is generally divided into one-time or multiple-use staplers, imported or Domestic stapler; it is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of manufacturing technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable for tightness, especially its fast suturing , easy operation, few side effects and surgical complications, etc., and it also enables tumor resection that was unresectable in the past; [0003] However, traditional staplers have the following defects: [0004] Tradition...
