Auxiliary device for bile duct cancer operation

Abstract

The invention discloses an auxiliary device for a bile duct cancer operation. When an operation part is clamped by the auxiliary device, a central hole groove communicated with a hollow air cavity is formed in an auxiliary clamping column; mesh grooves are formed in the outer side wall of the auxiliary clamping column; the mesh grooves are communicated with the central hole groove; the hollow air cavity is communicated with an air exhaust control mechanism; by means of the air exhaust control mechanism, an airflow at the mesh groove flows from the radial outer side of the mesh groove to the central hole groove, in this way, it can be effectively guaranteed that liquid or tiny tissue is prevented from dripping when tissue resected in an operation is clamped and taken out; the safety is effectively guaranteed in an air exhaust mode; the tissue extraction effect and reliability are improved; and the thoroughness of the operation is improved.

Description

Technical field [0001] The present invention is specifically a auxiliary device for bile duct cancer surgery involving medical assistance equipment. Background technique [0002] At present, for bile duct cancer surgery, it is generally removed by the surgery to resemble the lesion, and the current surgery knife is typically a knife or scissor structure. This simple structure is observed in the case of the lesion. As well as the removal, it is necessary to use tweezers to process, while the ordinary forceps are tapered, and the liquid or body fluid such as the existed lesion or body fluid will have a drop in such operations. This drip liquid or tissue has certain risk, which is easy to cause lesions in other parts, and therefore, ordinary tweezers have greater risk in such surgery, and the operation requirements of the surgical medical staff are higher, and It is difficult to monitor accurate monitoring of the surgical site. Inventive content [0003] Therefore, in order to solv...

AI Technical Summary

Problems solved by technology

[0002] At present, for cholangiocarcinoma surgery, a scalpel is generally used to resect the lesion, and the current scalpel is generally a knife-type or scissor-type structure. This simple structure is used to observe the lesion during surgery. And the removal after resection needs to be processed with tweezers, and when ordinary tweezers are clamping, blood or body fluids and other liquids or tissues in the excised lesion may drip. , this kind of dripping liquid or tissue has a certain risk, and it is easy to cause lesions in other parts. Therefore, ordinary tweezers have a greater risk in this kind of operation, and have higher requirements for the operation of the surgical staff, and Difficult to accurately monitor the surgical site
