Self-assisted retractor for surgical operation

Abstract

The invention relates to a self-assisted retractor for surgical operation. The retractor is characterized by mainly comprises an elevating device (9), a belt withdrawing device (10), a traction belt (11) and a hook plate (12), wherein the belt withdrawing device (10) is arranged at the upper end of an elevating lever (4) in the elevating device (9) and mainly comprises a shell (13), a telescopic belt withdrawing shaft (14) and a rocker arm (15); the main body of the telescopic belt withdrawing shaft (14) is positioned in the shell (13); the rocker arm (15) is connected with one end of the telescopic belt withdrawing shaft (14) and positioned outside the shell (13); the shell (13) is provided with a groove (16) for accommodating the rocker arm (15); and one end of the traction belt (11) isconnected with the telescopic belt withdrawing shaft (14), while the other end passes through a belt hole (17) on the shell (13) and is connected with the hook plate (12). The retractor has the advantages of simple structure, convenient manufacturing and use and low cost.

Description

technical field [0001] The invention relates to a medical device, especially a retractor used in surgery that can replace the manual retraction of the incision so that the operation field can be fully exposed, specifically a self-service retractor suitable for various operations. Surgical retractor. 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 physical labor,...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to design a retractor for a series of problems such as small applicable range, large volume, large number of parts, occupying a lot of operating space, affecting the doctor's station operation, and the pulling part cannot be moved arbitrarily at the bedside. This kind of structure is simple, it can be applied to any part of the traction, small size, the device of pulling the hook plate is collected in a cylindrical shell, and the lifting rod fixing device is simple in structure, easy to operate, stable and reliable, and will not affect the surgeon Pull chain cord built-in surgical retractor operated in standing position
