Assisted-free incision anal trocar

Abstract

The invention discloses an auxiliary incision-free anus cannula device, relates to a peritoneoscope surgical operation auxiliary instrument and provides an auxiliary incision-free anus cannula device which has the advantages that no scar is left on the abdomen, the postoperative pain is reduced to the greatest extent, the length of stay is shortened, the expense is reduced and the like. The auxiliary incision-free anus cannula device is provided with an outer cannula, a guide tube, a rear cover and an apparatus hole cover, wherein external threads are formed at the tail end of the outer cannula; the outer cannula sleeves the guide tube; internal threads which are formed at the rear cover are in threaded connection with the external threads at the tail end of the outer cannula; a conical part is arranged at the front end of the guide tube; a grip handle is arranged at the rear end of the guide tube; an apparatus hole is formed in the tail of the rear cover; internal threads at the apparatus hole cover are in threaded connection with external threads at the tail of the rear cover. A peritoneoscope lower left colon and rectum resection operation is completed without an abdomen wall auxiliary incision, the minimally invasive aim is achieved, an abdomen wound is more attractive, the occurrence of postoperative incisional hernia, incision infection, dehiscence, incision tumour abdomen wall plantation and the like is avoided, and the intestinal canal adhesion probability is reduced. The auxiliary incision-free anus cannula device has the advantages that tumour-free operation is realized, the operation is simple and convenient, and safety and reliability are realized.

Description

technical field [0001] The invention relates to an auxiliary instrument for laparoscopic surgery, in particular to an anal cannula device free of auxiliary incision. Background technique [0002] Laparoscopic surgery has gradually developed into colon and rectal resection since the 1980s. Laparoscopic colon and rectal surgery has the advantages of less trauma, faster recovery, and fewer complications, and can achieve the same effect as traditional open surgery. Rapid development. After more than 20 years of exploration and accumulation, laparoscopic-assisted colorectal surgery has become increasingly perfect. Minimally invasive surgery, as one of the important symbols of modern surgery, has attracted more and more attention from surgeons and patients. It is one of the development trends of tumor surgical treatment to minimize trauma and preserve function to the greatest extent under the premise of following the principle of radical surgery. In order to further reduce traum...
