Medical surgical soft tissue dilator

Abstract

A medical surgical soft tissue dilator comprises a main rod (1), a locking sleeve (2), a locking operating rod (3), a belt winding device locking sleeve (4), a belt winding device (5) and a hook plate (6). A half dovetail groove which matches with a surgical bedside is arranged at the lower end of the main rod (1), another half dovetail groove capable of vertically moving is arranged at the lower end of the locking sleeve (2), the locking operating rod (3) is provided with inner threads matching with outer threads at the upper end of the main rod (1), an inner screw hole which matches with the outer threads of the upper end of the main rod (1) is arranged at the upper end of the belt winding device locking sleeve (4), the lower end of the belt winding device locking sleeve (4) is covered at the upper end of the locking operating rod (3), the lower end of the belt winding device (5) is inserted in an inserting hole at the upper end of the main rod (1), the height of the belt winding device (5) is adjustable, and a belt winding box is disposed at the upper end of the belt winding device (5) and connected with the hook plate (6). The medical surgical soft tissue dilator is characterized in that a limiting groove (13) is arranged on an inserting rod (12) at the lower end of the belt winding device (5), and an elastic jaw (14) is arranged on the main rod (1) and provided with a one-way check bump (15) which is inserted into the limiting groove (13). Structural strength is guaranteed, simultaneously, utilization quantity of materials is greatly reduced, and the medical surgical soft tissue dilator has the advantages of high strength, light weight and convenience in operation and use.

Description

technical field [0001] The invention relates to a medical device, especially a retractor used in an operation that can replace the manual retraction of the incision so that the operation field can be fully exposed, specifically a medical surgical device suitable for various operations. Soft tissue expander. Background technique [0002] At present, in the operation of straight abdominal incision, such as general surgery, urology, obstetrics and gynecology, in order to obtain an ideal surgical field, it is necessary to keep the opened abdomen in a good retraction state; also in the operation of thorax, back and spine, etc. The incision also needs to be retracted. The existing method one is to rely on the surgical assistant to pull the incision apart from both sides with pull hooks, which is poor in effect and labor-intensive. People have invented various abdominal operation retractors to replace artificial traction for this reason, and people are liberated from heavy physica...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to design a retractor that can not only ensure the structural strength but also reduce the material consumption due to the problems of insufficient strength, heavy weight, and many consumables caused by the existing retractor's take-up device that is easy to fall off from the main rod and the rising height is too high. A medical-surgical soft tissue dilator with anti-dropping and position-limiting features
