Multi-directionally positioned retractor for hepatobiliary surgical operation

Abstract

The invention discloses a multi-directionally positioned retractor for a hepatobiliary surgical operation. The multi-directionally positioned retractor comprises a fixing device, a cover ring assemblyand a retracting assembly for retracting tissues around a surgical opening, wherein the cover ring assembly comprises surgical cover cloth and a fixing ring, the surgical cover cloth and the fixing ring are used for protecting a patient and positioning a surgical opening part, the fixing ring is fixedly connected with the fixing device, and the retracting assembly is in sliding connection with the fixing device. The fixing device comprises a supporting frame, a supporting table and a telescopic rod, wherein the supporting frame is fixed to an operating table, the telescopic rod drives the retracting assembly to lift vertically so as to pull the surgical opening open, an annular sliding groove is formed in the supporting table, and the telescopic rod is in sliding connection with the annular sliding groove. Under the condition of small surgical openings, when multiple foci exist in the body of a patient and surgeries conducted on other foci are needed, the retracting direction of the retractor is changed by turning the telescopic rod, and the telescopic rod is kept at the fixing position of the supporting table without an external force.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a traction device for hepatobiliary surgery with multi-directional positioning. Background technique [0002] Hepatobiliary surgery mainly treats diseases such as hepatobiliary and pancreatic tumors, cholelithiasis, and portal hypertension. In current clinical treatment, when liver tumors, liver cysts, gallbladder stones, and tumors are resected under laparoscopy, it is often necessary to use surgical instruments to lift the liver tissue, or to separate and pull the lesion and surrounding tissues. In this process, a retractor device is required. In order not to affect the doctor's vision during the operation, the traditional retractor device uses multiple retractors to pull the surgical incision outward in different directions. The surgical incision is hooked to make it expand outward. The existing retractors are generally fixed on the operating bed with nuts when in use. It is...

Problems solved by technology

In this process, a retractor device is required. In order not to affect the doctor's vision during the operation, the traditional retractor device uses multiple retractors to pull the surgical incision outward in different directions. The surgical incision is hooked to make it expand outward. The existing retractors are generally fixed on the operating bed with nuts when in use. It is very good to adjust the surgical field of view while taking into account the tightness of the connection. When it is necessary to adjust the tension degree of the surgical opening or the traction direction of the opening, it is necessary to reposition the retractor. The adjustment is cumbersome. Therefore, there is an urgent need for a Appropriate pulling device can avoid the occurrence of the above situation and increase the safety of operation
