Problems solved by technology

[0004] The invention solves the defect in the prior art that the instruments that perform circumferential purse-string suture on the surface of the digestive tract tissue in the abdominal cavity cannot enter the laparoscopic pneumoperitoneum for operation, and provides a method that enters the pneumoperitoneum through the laparoscopic working channel, and cooperates with laparoscopic pneumoperitoneum. Purse-string forceps for laparoscopic purse-string suture on the surface of digestive tract tissue in the abdominal cavity

Embodiment 1

[0029] Embodiment 1 Novel laparoscopic purse forceps of the present invention

[0030] See Figure 1-Figure 3 . attached figure 1 It is the structural representation of laparoscopic purse forceps of the present invention, appended figure 2 for figure 1 Enlarged schematic diagram of region A in the middle, with image 3 It is a schematic diagram of the connection of the clamp, the handle of the pliers, the connecting rod and the pull rod in the present invention.

[0031] A new type of purse forceps for laparoscopy, comprising a clamp 1, a handle 2, a sleeve 3, a fixed handle 4, a swing handle 5, the handle 2 includes an upper handle and a lower handle, an upper handle and a lower handle The handle is fixed on the head end of the casing 3 through the pin shaft 6, and the upper clamp handle and the lower clamp handle can rotate with each other. The rear end of the clamp handle 2 and the front ends of the two connecting rods 7 pass through two hinge shafts 8 A planar four-...

Embodiment 2

[0033] Embodiment 2 The improvement scheme of the present invention

[0034] The structure of the purse pliers of this embodiment is substantially the same as that of Embodiment 1, the difference is that there is an angle positioning device between the sleeve and the inner sleeve, so that the pliers are clamped at 30° and 60° to the plane where the pliers handle is located. , 90°, 120°, the angle between the clamp and the handle is fixed, which is convenient for intraoperative operation.

[0035] The structure of the sleeve 12 and the inner sleeve 13 and its connection mode are as follows: Figure 4 shown. The sleeve 12 is hollow tubular, and one end of the sleeve 12 is fixed on the surface of the pliers handle 2; a rotating shaft 14 is arranged inside the sleeve 12, and the rotating shaft 14 is arranged at the axial position of the sleeve 12 and fixed with the pliers handle 2 Connection; the rotating shaft 14 is provided with a slope 15 on the two parts close to the pliers ha...

Abstract

The invention relates to novel purse-string forceps for a laparoscope. The novel purse-string forceps comprise forceps clips, forceps handles, a sleeve, a fixed handle and a swing handle. The forceps handles include an upper forceps handle and a lower forceps handle, and the upper forceps handle and the lower forceps handle are fixed to the head of the sleeve by the aid of a hinge pin and can rotate relatively; the rear ends of the forceps handles and the front ends of two connecting rods form a planar four-bar expansion structure by the aid of two hinge shafts, the rear ends of the two connecting rods are connected with the front end of a draw bar by a connecting pin, the fixed handle is connected with the swing handle by a handle hinge shaft, the draw bar is arranged in the sleeve, and the tail end of the draw bar is fixedly connected with the swing handle. The novel purse-string forceps have the advantages that the novel purse-string forceps can be applied to laparoscopic surgery, the forceps clips can be fed into pneumoperitoneum of the laparoscope to be operated, and accordingly the shortcoming that apparatuses for carrying out circumferential purse-string suture on the surfaces of tissues of digestive tracts in abdominal cavities cannot be fed into pneumoperitoneum of existing laparoscopes to be operated in the prior art can be overcome.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a novel laparoscopic purse forceps. Background technique [0002] In surgical operations, since the invention of the first staple product in the 1960s, medical staplers have become an indispensable medical device in the process of assisting incision suturing. With the development of medicine and the research and development of medical device products, more and more staple products have been used clinically. It has become one of the indispensable tools for doctors. Doctors often use a tubular stapler to perform end-to-end anastomosis of the digestive tract. Before the anastomosis, the tissue must be sutured at one end to implant the nail head of the tubular stapler so that it can be firmly inserted into the central rod. Ligation, and then the implementation of tissue anastomosis. At present, many doctors sew the purse by hand, which cannot guarantee whether the amou...
