Tumor breaker used in cooperation with laparoscope

Abstract

The invention discloses a tumor breaker used in cooperation with a laparoscope. The tumor breaker comprises an outer sheath, an inner sheath and a pull rod; a cutting net is arranged in front of the pull rod; a first elastic piece capable of expanding or contracting the cutting net is arranged between the pull rod and the cutting net; the cutting net comprises a circumferential line and a plurality of longitudinal cutting lines; one end of each longitudinal cutting line is fixedly connected to the circumferential line, the other end of the corresponding longitudinal cutting line forms a closing part, the closing part is fixedly connected with a cutting knife; both ends of the first elastic piece are respectively fixedly connected to the front end portion of the pull rod and the circumferential line; the front of the inner sheath is provided with a containing bag, an opening end of the containing bag is provided with a second elastic piece, both ends of the second elastic piece are fixedly arranged at the front end portion of the inner sheath. The tumor breaker can uniformly cut tumors in the abdominal cavity, can also prevent tumor tissue from falling into the abdominal cavity, which not only speeds up the cutting of the tumors, but also facilitates rapid removal of all the tumor tissue from the abdominal cavity.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a tumor breaker used in conjunction with a laparoscope. Background technique [0002] When tumor resection is performed on organs in the abdominal cavity, if a large wound is cut in the abdomen, it will affect the postoperative recovery of the patient. In order to avoid large abdominal trauma, two holes with a diameter of 5mm and one hole with a diameter of 10mm can be opened on the abdomen, and surgical instruments such as lenses, light sources, and scalpels can be inserted into the holes to treat tumors on internal organs. removal. The tumor after removal is usually too large to be taken out directly through the hole opened on the abdomen. Therefore, a tumor crushing device needs to be inserted into the abdominal cavity. After the tumor crushing device crushes the tumor in the abdominal cavity, the crushed tumor tissue is taken out from the abdominal cavity through surgical in...
