Abdominal-tumor chopping and sucking device and method

Abstract

The invention provides an abdominal-tumor chopping and sucking device and method. The device is characterized in that the device is provided with an inner needle, an accommodating bag, a hollow pipe,a memory guide wire and an air valve the inner needle comprises a needle tube and a shell, the needle tube can be movably accommodated in the hollow tube body of the hollow tube, the shell is arrangedon the upper side of the needle tube, an accommodating groove is formed in the lateral wall of the bottom end of the hollow tube body to accommodate one part of the folded accommodating bag, the other part of the folded accommodating bag is accommodated in the hollow tube body, the opening of the accommodating bag is telescopically connected with the memory guide wire which is guided out for pulling, the top end of the shell is provided with a through hole and a sealing cap for covering the through hole, the through hole is communicated with the hollow tube body, the inner needle can move inthe hollow tube and be pulled away from the hollow tube, the inner needle can drive the accommodating bag to be separated from the hollow tube body, the memory guide wire can pull the opening of the separated accommodating bag to be connected with the bottom end of the hollow tube in a sleeved manner, and then the air valve is communicated with the hollow tube to perform air inflation to allow theaccommodating bag to expand to form a tumor chopping and sucking space isolated from the abdominal cavity of a patient.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive excision of abdominal cavity tumors, and in particular relates to a device and method for crushing and aspirating abdominal cavity tumors. Background technique [0002] At present, minimally invasive resection of intra-abdominal tumors is mostly performed by the following methods: [0003] Make an operation on the patient's abdomen and puncture three cannulae to establish access for instruments; [0004] Insert laparoscope, minimally invasive scissors, minimally invasive insert clips or minimally invasive cutting flusher or ultrasonic knife into the three cannula to achieve cutting, coagulation and removal of target tissue. [0005] When the cut tissue is a small-volume malignant tumor, ultrasonic scalpel and other instruments can ensure that the cut site does not bleed or the amount of bleeding is small. Because the bleeding point of the cut malignant tissue has been coagulated, it ca...
