Specimen extractor for minimally invasive surgery

Abstract

A minimally invasive surgical instrument for conveniently and completely extracting a cut specimen from a surgical cavity in a minimally invasive surgery comprises a sleeve, a core tube, a clamping strip and a specimen bag. The sleeve is a hollow tubular passage for other components to access the surgical cavity, the core tube is formed by four stainless steel elongated sheets connected at one end, a traction thread is fixed at the bottom center of the core tube, a traction ring for facilitating traction is arranged at the other end of the traction thread, a clamping socket is arranged on one sheet and used for insertion of the clamping strip, the clamping strip is an elongated stainless steel strip and matched with the clamping socket on the core tube in shape, the clamping strip can be inserted into the clamping socket and fixed therein, a barb is arranged at a position close to the bottom of the clamping strip and used for fixing an opening of the specimen bag, and a body of the specimen bag covers the bottom end of the core tube to contain specimens.

Description

Technical field [0001] The invention relates to a minimally invasive surgical instrument used in minimally invasive surgery to completely remove cut specimens from the surgical cavity. Background technique [0002] At present, in the minimally invasive surgery of the medical process, if it is necessary to remove the specimens excised during the operation, the usual method is to put the ordinary specimen bag into the surgical cavity through the minimally invasive surgical incision, and perform minimally invasive surgery in the surgical cavity. The instrument puts the specimen into the specimen bag, and then takes out the specimen bag together with the specimen through the minimally invasive surgical incision. The traditional method of specimen removal is inconvenient, time-consuming and labor-intensive to put the specimen into the specimen bag because of the indirect operation through minimally invasive surgical instruments in the limited surgical cavity. ; When taking out t...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects and deficiencies of inconvenient operation when putting the specimen into the specimen bag, increasing the risk of tumor or inflammation dissemination and anesthesia accident, unnecessary enlargement of the incision or destruction of the specimen when the specimen is taken by the traditional method in minimally invasive surgery, The present invention provides a brand-new minimally invasive surgery specimen taker, which can conveniently put the specimen into the specimen bag in the limited minimally invasive surgery space, reduce the risk of tumor or inflammation dissemination and anesthesia accident, and greatly reduce unnecessary Potential for enlarged incision or specimen destruction
