An excision tool for tumor surgery with an anti-off structure

Abstract

The invention discloses an excision tool for tumor surgery with an anti-detachment structure, comprising a sealing plug, an embedded needle and a connector; A sealing plug is installed in the middle of the side of the body, and an embedded needle is installed inside the sealing plug at the position coincident with the center line. A biopsy needle body is installed on the other side of the side of the connector cylinder and the center line of the sealing plug, and the biopsy needle body is fixedly installed in the connection. On the connector, the outer side of the sealing plug is provided with an external handle on the side of the cylindrical body of the connector; the gas extracted by the present invention is sucked from the top of the biopsy needle body, stored in the pressure tube through the connector, and then the biopsy needle body is sealed through the sealing plug The formed air pressure is discharged to the outside of the excision tool through the outer connecting tube, so as to continuously pressurize and suck out the tumor tissue and make it hang upside down on the inlay needle to achieve the double anti-detachment effect of the combined action of the air pressure and the hook.

Description

technical field [0001] The invention relates to the technical field of medical tumor tissue removal, in particular to a removal tool for tumor surgery with a removal-preventing structure. Background technique [0002] As a common malignant disease, the early diagnosis and treatment of tumors require the use of auxiliary tools for collection and removal. The initial removal method is completed by large-scale operations. With the advancement of medical conditions and science, this The surgical method that causes great harm to the human body is gradually replaced by the minimally invasive surgery. When the tumor is removed or the tissue is removed by the minimally invasive method, the tumor tissue is precisely aligned with a fine needle tube, and the tumor tissue in the part is extracted or removed, so as to achieve the purpose of removing the tumor. [0003] At present, the biopsy method of puncture biopsy needle is used for the preliminary examination of the tumor, and the fo...

AI Technical Summary

Problems solved by technology

[0003] At present, the pre-examination of tumors uses the biopsy method of puncture biopsy needles, and the tumors found in small areas, especially benign tumors, are taken out by puncture to avoid the damage to the human body due to surgery. Patent Nos. CN2402275Y, CN102551692A, CN204072260U are advanced The existing technologies all use the blocking method to prevent falling off. This blocking method is not guaranteed, and it is easy to fall off when the pressure is lost. Especially in the extraction of larger tumor tissues, due to its own gravity, the needle The wall of the tube is relatively smooth so that the removed tissue falls off during the process of taking it out. This kind of falling off itself will not cause harm to the body, but because it is any point of tumor tissue left in the human body, it will make the human body in this part fall off. There is also the risk of the same tumor lesions, and in the process of using the pressurized tube, due to improper operation or the quality of the tool itself, some or all of the pressure will be lost instantaneously, thus losing the adsorption force on the removed tissue, resulting in the existence of the removed tissue. risk of slipping
