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

The invention discloses a single-pole elevator, which is convenient to determine the position of a nervous tissue and peel pathological tissues in a surgery. The elevator comprises an elevator body and a lead wire, wherein the elevator body comprises a hand held part and an operation part; the operation part comprises a connecting section connected with the hand held part and a working end connected with the connecting section, and is made of a conductive material; the hand held part is insulated with the operation part; and the operation part is connected to one end of the lead wire, and a plug is connected to the other end of the lead wire, and the lead wire is insulated with the hand held part. In the surgery, the operation part is controlled by a current stimulation box to discharge electricity, the current stimulates the nervous tissue on the periphery of pathological change, and the distributing position of the nervous tissue on the periphery of the pathological change can be observed on an electromyogram, so that an operator can determine the position of the nervous tissue as soon as possible in the surgery to protect the nervous tissue from injury.
Description
technical field [0001] The invention relates to a monopolar 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 als...
