Trans-anorectal object taking device with protective plug cap for laparoscopic surgery

Abstract

The invention discloses a trans-anorectal object taking device with a protective plug cap for laparoscopic surgery. The device is characterized by being composed of the protective plug cap, a tractionwire, a sheathing tube, a sealing cap, an elastic metal ring, an object taking bag and a guiding rod; the surface of the protective plug cap is smooth, and the protective plug cap can be connected with and separated from the distal end of the sheathing tube; one end of the traction wire is connected with the protective plug cap, and the other end of the traction wire can be connected with the distal end of the sheathing tube or an elastic metal ring; the sheathing tube is of a hollow tubular structure, and the proximal end of the sheathing tube is connected with the sealing cap; the sealing cap is made of an elastic material; the elastic metal ring is connected with an opening of the object taking bag and connected to the distal end of the guiding rod; the object taking bag is of a bag-shaped structure; the distal end of the guiding rod is connected with the elastic metal ring, and the proximal end of the guiding rod is a handle. The elastic metal ring, the object taking bag and the guiding rod are arranged in the sheathing tube, when the sheathing tube passes through the anorectum and enters the enterocoelia, the protective plug cap can prevent the anorectum from being damaged byan opening of the sheathing tube and prevent the situation that intestinal content flows into the sheathing tube and causes bacterial contamination on the object taking bag, and therefore the surgical complications are reduced.

Description

technical field [0001] The invention relates to a device for taking out specimens resected by laparoscope through anorectum. Background technique [0002] Traditional laparotomy is traumatic. In recent years, laparoscopic surgery has been widely used, with less trauma and faster recovery. It uses abdominal wall puncture to form single or multiple small channels in the abdominal wall, so that laparoscope and surgical instruments can enter and exit the abdominal cavity for surgical operations. . However, it is difficult to remove large tumors through laparoscopic surgery through small incisions on the abdominal wall. At present, after intestinal tumor resection, the natural orifice can be used, that is, the anorectal access can be used to remove them. In order to prevent tumor spread, traditional retrieval bags are mainly used. Due to the open and sharp edge of the sheath tube containing the retrieval bag, on the one hand, the sheath tube opening may damage the anus or intest...

However, it is difficult to remove large tumors through laparoscopic surgery through small incisions on the abdominal wall. At present, after intestinal tumor resection, the natural orifice can be used, that is, the anorectal access can be used to remove them. In order to prevent tumor spread, traditional retrieval bags are mainly used. Due to the open and sharp edge of the sheath tube containing the retrieval bag, on the one hand, the sheath tube opening may damage the anus or intestinal wall when it is inserted through the anus and intestinal tract, and on the other hand, it may cause intestinal contents to flow into the sheath Tube contamination of the retrieval bag, especially when the contaminated retrieval bag expands in the abdominal cavity, may cause the contamination bacteria in the intestinal tract to spread to a wider range in the abdominal cavity, thus increasing the chance of iatrogenic surgical infection
