Clamping forceps used for tumor

Abstract

The invention relates to clamping forceps, and particularly discloses clamping forceps used for a tumor. The clamping forceps comprise two clamping ends and are characterized in that the clamping ends are in an arc shape bending inwards, and anti-slipping patterns are arranged on the inner walls of the clamping ends; a tooth rake head is arranged at the end of one clamping end in the direction of facing the other clamping end, and teeth of the tooth rake head are in a flat end, or acute end or blunt end shape. The clamping forceps can prevent the tumor from disengaging, do not destroy the surface of the tumor or damage the blood vessels of the tumor, can provide a clean and broad visual field, and are beneficial for smooth completion of operations.

Description

(1) Technical field [0001] The invention relates to a clamping tweezers, in particular to a clamping tweezers for tumors. (2) Background technology [0002] For most patients with brain tumors, surgical resection of brain tumors is still the preferred treatment method. With the cooperation of surgical microscopes and other instruments, tumor removal can relieve the pressure of tumors on important structures of the brain such as nerves and blood vessels, and reduce intracranial pressure. Compression, eliminate local focal compression symptoms, and enable patients to recover. [0003] Brain tumor resection emphasizes the principle of visual operation, and the boundary between the tumor and the surrounding normal tissue must be separated under the visual field, and operations such as separation and electrocoagulation should not be performed blindly outside the visual field, otherwise important surrounding nerves may be damaged , blood vessels, leading to serious consequenc...

AI Technical Summary

Problems solved by technology

[0004] If you use tweezers for holding tumors, because the surface of the tumor is wet and slippery, the brain tumor often cannot be clamped during the operation, or the assistant is unable to hold on for too long and loosens the tweezers, causing the tumor to fall off. These two situations occur , when there is a rupture of a large blood vessel, it is difficult for the operator to find the rupture again, and successful electrocoagulation can lead to serious complications or death of the patient; in addition, the surface of some tumors is soft and crisp, and the blood supply is abundant. The tumor cannot be clamped at all with clamping forceps, or it bleeds after a little clamping. The tumor is difficult to expose, which makes the operation difficult.

[0005] If a brain tumor retractor is used, it only pulls the tumor in one direction, and there are also defects such as looseness and incomplete exposure.
