Description

Self-traction rear-separation blocking traction device

Technical Field

The invention belongs to the field of medical instruments, relates to a blocking traction device used in an operation, and particularly relates to a self-traction posterior detachment (SPLT) blocking traction device which is used in a laparoscopic gastrointestinal operation. The device facilitates the completion of a post-occlusion self-traction-amputation (SPLT) digestive tract reconstruction procedure.

Background

In recent years, the development of laparoscopic gastrointestinal surgery is rapid in clinical medical practice, wherein the completion of gastrointestinal reconstruction under a laparoscope is still the technical bottleneck of the full-laparoscopic development of gastrointestinal surgery. The self-pulling out (SPLT) laparoscopic anastomosis technique significantly simplifies this procedure, taking the laparoscopic gastrointestinal anastomosis procedure as an example: 1) Comprises the ligation of the esophagus at the junction of the esophagus and the stomach or the upper edge of the tumor; 2) The cleaning of the hiatus and the periphery of the lower esophagus and the dissociating of the lower esophagus and the linear anastomosis of the esophagus and the jejunum are completed under traction, the common opening is closed, and the esophagus and the jejunum are separated at the same time. The core of the SPLT technology is that ligation and blocking of a tumor specimen of the digestive tract are performed, a ligature is applied to pull the digestive tract, anastomotic reconstruction of the remaining digestive tract is completed in a traction state, and finally the specimen is separated.

At present, no material device specially used for traction under a laparoscope exists in the market, common hemp ropes and yarns are used for traction in common clinical practice, and no specific model exists, and the thickness and the length are not fixed, so that the material device appears: some are not easy to knot, and some are easy to slip, which affects the effect and safety of operation traction. On the other hand, because the traction devices are not fixed consumables in an operating room, special disinfection is required before operation, and development designs such as lead-free lines and the like are avoided, so that the hidden danger that the traction devices are scattered in the abdominal cavity and are not easy to find and take out exists; moreover, in the practical operation of some mechanisms, because corresponding hemp ropes and yarn belts are not provided, double J tubes (pigtail catheters) and the like are temporarily used for replacing the hemp ropes and the yarn belts, the price and the cost are high, knotting is difficult, and the pulling effect is not ideal; and the like, a novel traction device is clinically needed at present, can be conveniently brought into the abdominal cavity, can be knotted easily under the laparoscope, is easy to pull at the tail part, and has the characteristics of image development and the like (easy radiography positioning).

Based on the current state of the prior art, the inventor of the application intends to provide a blocking traction device used in the operation, in particular to a self-traction posterior disconnection (SPLT) blocking traction device, which is used in the laparoscopic gastrointestinal surgery. The device facilitates the completion of a post-occlusion self-traction-detachment (SPLT) digestive tract reconstruction procedure.

Disclosure of Invention

The invention mainly aims to solve the practical clinical problem that a device for conveniently blocking and dragging a digestive tract is lacked under a laparoscope, and provides a blocking traction device used in the operation, in particular to a self-traction back-off (SPLT) blocking traction device. The device facilitates a self-traction posterior detachment (SPLT) digestive tract reconstruction surgery step after the completion of the blockage of the laparoscopic gastrointestinal surgery.

The SPLT breaking and pulling device comprises an easily plastic metal body (1), a pulling yarn belt (2) and a linking part (3) (as shown in figure 1).

In the invention, the metal main body is an easily plastic metal; the drawing yarn belt is the drawing yarn belt.

More specifically, the present invention is directed to a method for producing,

the self-traction back Separation (SPLT) blocking traction device (called as SPLT blocking traction device for short) is designed to be a section of plastic linear soft metal material with the length of about 5cm as a main body, two ends of the device are connected with yarn belts with the length of about 5cm respectively, the purpose of blocking surgical specimens is achieved by screwing metal parts in a rotating way, and the yarn belts at the two ends can be pulled by a surgeon.

In the invention, the metal main body (1) is a blocking main body, and the linear main body is formed by a plastic metal material part so as to screw the main body to realize knot-free.

In the invention, the drawing yarn belt (2) is a drawing part, is made of yarn belt, cotton or other various soft materials and is used for drawing.

In the present invention, the link member may be a link member made of various materials, or may be implemented by combining the members (1) and (2) without adding a member (punching a hole in the body member 1).

In the present invention, the main body and the traction part may be integrally designed or separately sterilized to place the temporary link.

In the invention, the main body and the traction part can be linear components without marks or components with scale marks.

In practical use (as shown in fig. 2), a) after the SPLT traction device is brought into the abdominal cavity from the Trocar wound of the abdominal wall, the plastic metal strip of the component 1 is wrapped around the tissue of the gastrointestinal tract to be pulled by pulling the yarn strip part of the component 2; b) The component 1 is screwed down by rotating the blood vessel forceps or the tissue separating forceps under the laparoscope in the same direction; c) In order to tighten the assembly 1 and then block the digestive tract, the assembly 2 is used for subsequent traction to complete the digestive tract anastomosis and separation step under the laparoscope; meanwhile, the component 1 is a plastic metal body, and can be developed under the imaging of an X-ray film and the like, so that the requirement of convenience and safety for finding abdominal cavity equipment is met.

The SPLT blocking traction device is endowed with a blocking function of non-knotting under a laparoscope and a traction function of a digestive tract under a blocking retroperitoneal laparoscope, which are lacked in the prior art, in design, the application is flexible and convenient due to the integrated plastic design, and the related blank of clinical application is filled. The medical treatment instrument is simple in manufacturing process, convenient to use, low in daily maintenance cost, strong in practicability, beneficial to improvement of medical treatment working efficiency and high in clinical application requirement.
