An object retrieval device for laparoscopic surgery

Abstract

The invention discloses an object extraction device for laparoscopic surgery. The extraction device comprises a reducing sleeve, a guiding push rod and an object extracting assembly, the reducing sleeve is a hollow tubular structure, a sealing cap is arranged at one end of the reducing sleeve, the extraction assembly includes an extracting bag opened at both ends and a sealing rope provided at oneend of the extracting bag, one end, provided with the sealing rope, of the extracting bag is placed in the reducing sleeve, the other end is overturned outwards, sleeves the outer periphery of the end portion of one end, provided with the sealing cap, of the reducing sleeve, and is compressed by the sealing cap, one end of the sealing rope is used for tightening the bag opening of the extractingbag, the other end of the sealing rope extends out of the surface, in contact with the sealing cap, of the reducing sleeve along the outer side of the extracting bag, one end of the guiding push rod is placed in the extracting bag, and can push one end, provided with the sealing rope, of the extracting bag out of the reducing sleeve, and the other end of the guiding push rod goes through the sealing cap and extends out of the reducing sleeve. The object extraction device can prevent the anorectum from being damaged, and can also prevent the intestinal content from bacterially contaminating theextracting bag in order to reduce surgical complications.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to an object fetching device for laparoscopic surgery. Background technique [0002] Traditional laparotomy has relatively large trauma, while laparoscopic surgery has less trauma and faster recovery. It has been widely used in clinical practice in recent years. It uses abdominal wall puncture to form single or multiple small channels in the abdominal wall, so that laparoscope and surgical instruments Access to 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. However, because the opening of the sheath tube containing the retrieval bag is o...

Problems solved by technology

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. However, because the opening of the sheath tube containing the retrieval bag is open and has sharp edges, on the one hand, the sheath tube opening may damage the patient's anus or intestinal wall when it is inserted through the anus and intestinal tract; on the other hand, it may cause the patient's bowel The content flows into the sheath tube to pollute the retrieval bag, especially when the contaminated retrieval bag expands in the abdominal cavity, it may cause the pollutant bacteria in the intestinal tract to diffuse into the abdominal cavity, thereby increasing the chance of iatrogenic surgical infection, and the traditional retrieval method The object device cannot play a sealing role, which may easily cause pneumoperitoneum leakage, affect the doctor's surgical sight, and increase the risk of surgery
