Incision expansion support convenient to adjust and used for general surgery department operation

Abstract

The invention discloses a convenient-to-adjust incision expansion support for general surgery department operation, and relates to the technical field of general surgery department operation tools. A first support rod and a second support rod; a first universal rotating head; the direction fine adjustment assembly comprises a base connected with the first universal rotating head, the outer side of the base is connected with a supporting plate through a second universal rotating head, annular sliding grooves are formed in the base and the supporting plate, sliding blocks are arranged in the two sliding grooves in a sliding mode, and first screw rods are hinged to one sides of the sliding blocks arranged in the supporting plate; a threaded cylinder is rotationally arranged on one side of the other sliding block, and the end of the first screw extends into the threaded cylinder and is in threaded connection with the threaded cylinder; the first sliding rod is provided with a distance fine adjustment assembly, and an expansion assembly is arranged between the first sliding rod and the second sliding rod in a sliding mode. When the position of the expansion assembly is adjusted, the general position of the expansion assembly is adjusted through the first universal rotating head, then the precise position of the expansion assembly is adjusted through the fine adjustment assembly, and follow-up operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of general surgical instruments, in particular to an incision expansion support for general surgical operations with convenient adjustment. Background technique [0002] General surgery is a clinical discipline that treats liver, biliary tract, pancreas, gastrointestinal, anorectal, vascular disease, thyroid and breast tumors and trauma as the main method of surgery. It is the largest specialty in the surgical system. [0003] In the existing operation, there are many incisions or wounds. In order to obtain a better view, the surgical incision needs to be expanded by means of instruments for better operation. At present, the commonly used method is to use surgical retractors or expandable stents. However, the traditional expansion stent is roughly adjusted according to the patient's posture and then expands the incision, and cannot be precisely adjusted for the incision surface, resulting in unstable stent ...

AI Technical Summary

Problems solved by technology

However, the traditional expansion stent is adjusted in a general range according to the patient's posture and then the incision is expanded, which cannot be precisely adjusted for the incision surface, resulting in instability or other accidents when the stent is supported.
