Problems solved by technology

[0005] Existing staplers generally use metal staples or degradable material devices for anastomosis. Metal staples will stay in the human body for a long time and easily cause intestinal stenosis, while devices made of degradable materials are generally large, which seriously affects the patient's eating before degradation and digestion, and the collapsed device will cause damage to the human stomach

Embodiment 1

[0034] This embodiment provides an improved intestinal cavity stapler, such as Figure 1-3 As shown, the intestinal anastomat includes an outer cylinder 1, a first inner cylinder 2, a second inner cylinder 3, and a pull rod 4, which are coaxially sleeved in sequence from outside to inside and fitted to each other. The top 5 and the anastomotic line 7 at the upper end; the top 5 includes an elastic base 51, an elastic cover 52 covered on the elastic base 51 and a connecting ring 53 connected to the inner periphery of the middle part of the elastic cover 52, the pull rod 4. The top end protrudes above the elastic base 51 and is connected to the connecting ring 53 through the connecting rod 54; the anastomotic line 7 includes a circular line 71, a plurality of short lines 72 connected to the circular line 71 at intervals, and a plurality of short lines 72 connected to the short line 72. The superabsorbent resin ball 73 on the free end can be relatively staggered in the axial dire...

Embodiment 2

[0038] This embodiment provides a superabsorbent resin ball, for example, the superabsorbent resin ball 73 is a starch-grafted acrylate polymer cross-linked product or an acrylamide-acrylate copolymerized cross-linked product. It has the characteristics of high multiple, high strength and not easy to decompose.

Embodiment 3

[0040] This embodiment provides a bar-shaped groove and an annular wire, and the end of the bar-shaped groove 82 is set as a tip, so that the icicles generated in the bar-shaped groove 82 have a sharp point and can easily pass through the folded part of the intestinal cavity. 10-12 short wires 72 are arranged at intervals on the annular wire 71, so as to improve the firmness of the connection at the folded part of the intestinal cavity.

Abstract

The invention discloses an improved intestinal cavity stapler which comprises an outer cylinder, a first inner cylinder, a second inner cylinder and a pull rod, which are arranged on the top of the pull rod, an anastomosis line and an ice-making mold, and are coaxially sleeved from the outside to the inside and are mutually adhered. When the intestinal cavity anastomosis is carried out by the intestinal cavity anastomosis device of the invention, it is possible to utilize an annular line in a frozen state, Short-line and high water-absorbent resin ball anastomosis ring intestinal incision canimprove the efficiency of suture, and the anastomosis material remains less in the body and is easy to discharge, reducing the occurrence of complications of operation, without degradation of metal nails, less harm to human body, and can play the role of hemostasis in anastomosis, prevent postoperative anastomotic bleeding, avoid re-operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an improved intestinal cavity stapler. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers , Lung cutting stapler, etc. [0003] The prior art discloses a disposable linear anastomat that can replace multiple rows of staples, which is a supporting device for a disposable linear stapler, and is equipped with a disposable linear anastomosis that can replace multiple rows of staples The device is especially suitable for sealing stumps and incisions in gastrointestinal sur...
