Surgical retractor system

Abstract

The invention discloses an operation traction system which comprises a positioning ring, a supporting mechanism, a horizontal traction mechanism and a vertical traction mechanism, the positioning ring is of a long-ring-shaped structure, and a plurality of positioning hole sets are formed in the upper side of the positioning ring, so that the traction mechanisms can be installed at proper positions according to operation requirements; the two supporting mechanisms are installed on the left side and the right side of the positioning ring respectively and can enable the traction system to move and lock in three directions in the space, the horizontal traction mechanism and the vertical traction mechanism can be connected with and detached from the positioning ring, the horizontal traction mechanism can achieve horizontal traction of a wound, the traction angle and force can be adjusted, and the vertical traction mechanism can be connected with and detached from the positioning ring. The vertical traction mechanism can realize vertical stable traction on tissues in a wound, and the vertical traction mechanism can also perform horizontal telescopic adjustment, so that the traction position, the traction angle and the traction force can be adjusted; a plurality of horizontal traction mechanisms or vertical traction mechanisms can be installed on the positioning ring at the same time, and multi-angle simultaneous traction of wound tissue is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical retraction system. Background technique [0002] In liver transplantation, liver lobectomy, biliary tract surgery, total or proximal gastrectomy, splenectomy and other abdominal operations, in order to obtain an ideal surgical field of view, it is necessary to keep the opened abdomen in a good retraction state, so that doctors can carry out For surgical operations, retractors must be used at this time. Retractors refer to a type of medical device that is in contact with human body tissues during surgery to obtain a surgical field of view and surgical space; at this stage, retractors for abdominal wounds The method is mainly through manual pulling. When exposing the surgical field of view, pulling in multiple directions is often required at the same time. This requires multiple medical personnel to perform pulling operations at the same time, which consumes ...

Problems solved by technology

[0002] In liver transplantation, liver lobectomy, biliary tract surgery, total or proximal gastrectomy, splenectomy and other abdominal operations, in order to obtain an ideal surgical field of view, it is necessary to keep the opened abdomen in a good retraction state, so that doctors can carry out For surgical operations, retractors must be used at this time. Retractors refer to a type of medical device that is in contact with human body tissues during surgery to obtain a surgical field of view and surgical space; at this stage, retractors for abdominal wounds The method is mainly through manual pulling. When exposing the surgical field of view, pulling in multiple directions is often required at the same time. This requires multiple medical personnel to perform pulling operations at the same time, which consumes a lot of human resources and cannot be effectively fixed. Stretching is unstable, not only the medical staff is prone to fatigue, but also makes the operation space more cramped, which is not conducive to the operation

[0003] Most of the existing retractors have a forceps structure, which has problems such as single function, few retraction directions, inability to adjust the retraction force on one side independently, and occupying the surgical field of view. It cannot achieve the ideal retraction effect, nor can it completely replace manual Therefore, it is necessary to develop a retraction system with comprehensive functions, which can retract in multiple directions at the same time, and can independently adjust the retraction force in each direction, so as to liberate the medical staff from the heavy and monotonous retraction work and reduce the The cost of surgery, the effect of improving the quality of surgery, has obvious economic benefits and social significance
