Bipolar dissector

Abstract

The invention discloses a bipolar dissector, which is convenient to verify the positions of nervous tissues in an operation and dissect pathological tissues. A core bar isolated with an operation part is arranged in the operation part of the elevator, and extends out of one end of the operation part to the other end thereof; the operation part and the core bar are made of conducting materials, and a hand-held part is isolated with the operation part and the core bar; the bipolar dissector further comprises two groups of conducting wires, namely, a first group of conducting wires and a second group of conducting wires, one end of the first group of conducting wires is connected with the operation part, and the other end of the first group of conducting wires is connected with a first plug;one end of the second group of conducting wires is connected with the core bar, and the other end of the second group of conducting wires is connected with a second plug; and the two groups of conducting wires are isolated from the hand-held part. During operation, a current stimulating box is used for controlling the electric discharge of the operation part, current stimulates the nervous tissues around the pathological part, and the distribution positions of the nervous tissues around the pathological part can be observed through an electromyogram, thereby bringing convenience for operator to verify the positions of nervous tissues as soon as possible in the operation and avoiding the injury of the nervous tissues.

Description

technical field [0001] The invention relates to a bipolar dissector for surgery. Background technique [0002] The stripper is a commonly used medical device, generally including a connected hand-held part and an operating part. The operating part includes a connecting section and a working end connected with the connecting section. The connecting section of the operating part is connected with the hand-held part. Hold the hand part, and peel the tissue from the human body through the working end of the operating part. According to the nature of the operation, the working end of the operating part has a hook shape, a sheet shape, and a roller shape. Although this traditional dissector can dissect the tissue conveniently, in neurosurgical posterior fossa diseases, the lesion is often closely related to the cranial nerve, and sometimes even surrounds the nerve tissue. Due to the compression and deformation of the nerve by the lesion, the anatomical position of the nerve also ...

AI Technical Summary

Problems solved by technology

Due to the compression and deformation of the nerve by the lesion, the anatomical position of the nerve also changes. During the operation, it is difficult to determine the exact position of the nerve fiber through the naked eye or a microscope, which makes it easy to damage the nerve tissue during the surgical operation through the stripper, causing patients Postoperative neurologic dysfunction or aggravation
