Enveloping adhesive type tumor resection scissors

Abstract

The invention discloses enveloping adhesive type tumor resection scissors. The enveloping adhesive type tumor resection scissors comprise a hinged column and a pin, wherein the pin is movably connected with a first scissors head and a second scissors head, the side, close to the pin, of the hinged column is movably connected with a third scissors head and a fourth scissors head, the third scissorshead is fixedly connected with a second handle, and the fourth scissors head is fixedly connected with a first handle; connecting blocks are fixed at the end, away from the hinged column, of the third scissors head and the end, away from the hinged column, of the fourth scissors head respectively, extrusion springs are fixed on the first scissors head and the second scissors head respectively, the extrusion springs are fixedly connected with connecting blocks, and a fixed rod is fixedly connected between the hinged column and the pin. The enveloping adhesive type tumor resection scissors havethe advantages that it can be ensured that the situation of relative sliding between the tumor and the scissors heads cannot occur during resection, resection space of the scissors heads cannot be occupied, the collection effect is better, a tumor body can be effectively prevented from scattering and falling off, the practicability is strong, and the enveloping adhesive type tumor resection scissors are very worth popularizing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a surrounding adhesive tumor resection scissors. Background technique [0002] In tumor removal surgery, medical staff use scalpels or surgical scissors with tweezers and other medical instruments to complete the operation. During this process, a combination of blunt and sharp dissection is often required to separate the tumor from the surrounding healthy tissue. Moreover, the scissors used in the existing tumor removal surgery generally extend the pliers into the patient's part through a small opening for resection, but there is no collection device on the existing surgical scissors, which may cause tumor cells to fall off, thereby causing tumors in the chest cavity. Spread within. [0003] In order to solve the above-mentioned problems, a tumor resection scissors with application number "201620085167.7" includes a first handle and a second handle, the front ends of the...

Problems solved by technology

[0004] However, the above-mentioned resection scissors still have obvious defects during use: 1. The end of the scissors near the head of the scissors is in an open state, which cannot surround the tumor well and perform resection, which may cause the tumor to be separated from the tumor during the resection process. The head of t
