Intestinal anastomosis machine for infants

Abstract

The invention discloses an intestinal anastomosis machine for infants. The intestinal anastomosis machine comprises an operating device and an auxiliary device, wherein the operating device comprisesa grasping handle, a wire passing pipe and a motion head; a hydraulic cylinder is mounted at the lower part of the inner side of the grasping handle; keys are mounted at the upper part of the front side of the grasping handle; an electricity connector is mounted at the bottom end of the grasping handle; the wire passing pipe is fixedly mounted at the top end of the grasping handle; a threaded seatis fixedly mounted at the top end of the wire passing pipe; the motion head is rotatably connected to the upper part of the threaded seat; and a pull rope is fixedly mounted at the top end of the hydraulic cylinder. The intestinal anastomosis machine disclosed by the invention is reasonable in structural design and ideal in matching effects; during operation, the situation that the fixation of the end surface is not firm, so that deflection and malposition are generated can be avoided; when the intestinal anastomosis machine is applied to a tiny intestine, the sewing operation is convenient to perform through arranged auxiliary equipment, and the surgery effect is better; compared with a rotation closing manner, the intestinal anastomosis machine disclosed by the invention is stable in clamping, and the situation that an intestine body slides from the open end can be avoided; and the technique of the intestinal anastomosis machine is subsidized by the 2017 National Natural Science Foundation of China (81770512) and 2018 "Sanming Project "(SZSM201812055) of Shenzhen city National Health and Family planning Commission.

Description

technical field [0001] The invention relates to an anastomotic device, in particular to an intestinal stapler for infants. Background technique [0002] Intestinal anastomosis is one of the most common operations in abdominal surgery, and it is also a surgical technique that surgeons must master. It is a key technique for digestive tract reconstruction and is related to the success of the operation. An ideal intestinal anastomosis should avoid complications such as anastomotic leakage, stenosis, and bleeding, and ensure operational stability. Improving and innovating anastomosis technology has always been a hot spot in surgical research. Up to now, hundreds of anastomosis methods have been developed. The significance of anastomosis is to stabilize the wound surface and facilitate suturing. However, these methods have their own advantages and disadvantages, but none of them can fully meet the requirements of use, especially when dealing with infants and young children, becau...

AI Technical Summary

Problems solved by technology

However, these methods have their own advantages and disadvantages, but none of them can fully meet the requirements of use, especially when dealing with infants and young children, because the intestines of infants and young children are thin and the lesion range is small, the most commonly used manual suture and stapler in clinical practice Neither method can well avoid the occurrence of complications such as anastomotic leakage and stenosis

[0003] The anastomotic effect of the existing stapler is not ideal, especially in the operation, it is easy to appear that the end face is not firmly fixed, offset and misplaced, resulting in postoperative mouth leakage. When dealing with small intestinal tubes, there is no special auxiliary equipment, which makes the suture The operation is time-consuming and laborious, the operation effect is poor, and the narrowing of the suture is prone to occur. Moreover, the existing anastomotic device adopts a rotating and closing method for anastomosis. Under the action of rotating extrusion, the intestinal body will also be squeezed from the rotating end to the opening end. Slide out of the staple cartridge, poor operational stability
