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 unsta

Example Embodiment

[0036] Embodiment 1: The installation process of the horizontal pulling mechanism 2 on the positioning ring 1:

[0037] ① Determine the installation position of the horizontal pulling mechanism 2 according to the needs of the operation, that is, determine the positioning hole group;

[0038] ② Rotate the first hand wheel 11 counterclockwise to move the front end backward;

[0039] ③Insert the two first positioning rods 13.1 on the lower side of the support platform 13 into the large holes in the two positioning holes 1.1 of the positioning hole group respectively, and pull the support platform 13 backward so that the two first positioning rods 13.1 reach the two positioning holes. The rear end position of the elongated hole in the positioning hole 1.1; ④ turn the first handwheel 11 clockwise to make the front end press the outer side of the positioning ring 1, so as to realize the fixing of the horizontal pulling mechanism 2 on the positioning ring 1.

[0040] Disassembly proce...

Example Embodiment

[0044] Embodiment 2: When the pulling angle of the horizontal pulling mechanism 2 needs to be adjusted:

[0045] ① Rotate the first locking ring 15 counterclockwise to release the compression state between the fourth ring teeth 12.2 and the third ring teeth 13.4;

[0046] ② Turn the first turntable 12 to a suitable angle;

[0047] ③Turn the first locking ring 15 clockwise to press the fourth ring tooth 12.2 and the third ring tooth 13.4, thereby locking the angle of the first turntable 12.

[0048] The pulling angle adjustment principle of the vertical pulling mechanism 3 is the same as above.

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.
