Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to a tissue extraction apparatus for getting sample operation through natural orifice.
Background
The laparoscopic surgery gradually develops from the 20 th century and 80 th century to the colotomy and proctostomy, and the laparoscopic colon and rectum surgery has the advantages of small wound, quick recovery, less complications and the like, can achieve the same effect as the traditional open surgery, and is rapidly developed. Over 20 years of exploration and accumulation, laparoscopic assisted colorectal surgery has become more sophisticated. Minimally invasive surgery is more and more concerned by surgeons and patients as one of the important marks of modern surgery, and the trend of the current tumor surgical treatment is to reduce trauma as much as possible and retain functions to the greatest extent on the premise of following the principle of radical operation. In order to further reduce the trauma and achieve better cosmetic effect, the scholars propose the concept of 'scarless operation'. Peter Wilk first proposed the concept of Natural Orifice Transluminal Endoscopic Surgery (NOTES) in 1994, which means that a soft endoscope is inserted into a body cavity by using a Natural orifice, and the wall of the cavity organ is punctured into the abdominal cavity to complete the operation of the internal organs in the abdominal cavity. However, as an emerging surgical technique, NOTES is not yet developed in clinic and still needs a long time of practice and exploration. Under the condition that NOTES operation is not available, the problem related to abdominal incision can be avoided through Natural orifice specific surgery (NOSES), postoperative recovery is quicker, postoperative cosmetic effect is better, and the concept of quick rehabilitation surgery is more met. In recent years, NOSES have been tried in clinical practice, and proved to be safe and feasible, with good results.
The tradition is in order to maintain pneumoperitoneum state, need to seal the mouth of pipe of tissue centre gripping extractor and sleeve pipe ware or cover bag, can adopt the helicitic texture to seal between sleeve pipe ware and the extractor, but the helicitic texture is sealed comparatively troublesome to there is the clearance in the helicitic texture, takes place gas leakage phenomenon easily.
