CN103784181A - Disposable monopole probe - Google Patents

Abstract

The invention discloses a disposable monopole probe and belongs to the field of medical instruments. The disposable monopole probe comprises a handle and a probe body. A probe head of the probe body is of a circular annular shape. When the disposable monopole probe is used in cooperation with a nerve monitor in a craniocerebral operation and a spinal cord operation, the circular annular monopole probe enables a tumor to be stripped out of the basis cranii nerve, and the nerves in the different incision tissues are accurately located through continuous current stimulation. Currents are adjustable in different operation stages. Through analysis of a waveform of the currents, a surgeon can be warned of the general position of the target nerve, and the operation effect is effectively improved.

Description

Disposable use one pole probe

Technical field

Patent of the present invention belongs to medical mechanical domain, specifically disposable use one pole probe.

Background technology

Disposable use probe is a kind of conventional medical accessory, and itself and nerve monitor support the use.In surgical operation, be first connected with nerve monitor, be then inserted in the muscle that needs the nerve control of surveying, the stimulating current of nerve monitor output is delivered in muscular tissue by the probe of probe.At present, existing disposable use probe, its probe is cylindrical-shaped structure, be used for the operation that the normal risk such as thyroid, the parotid gland is lower, and carry out in the process of craniocerebral operations and these excessive risk operations of operation on spinal cord, how can run into the situation that nervous tissue is covered by tumor parcel, as use common probe to peel off tumor tissues, cylindric probe protrudes into tumor tissues and very easily causes tumor tissues to break, and causes postoperative multiple complications.

Summary of the invention

Technical problem to be solved by this invention is that existing disposable use probe is not suitable in craniocerebral operations and operation on spinal cord, is unfavorable for tumor complete peeling off from basis cranii nerve.

The technical scheme that the present invention solves the problems of the technologies described above employing is: disposable use one pole probe, comprise handle and probe, and the probe of probe is annular.

The invention has the beneficial effects as follows, the probe of probe adopts cirque structure, carrying out in the process of craniocerebral operations and operation on spinal cord, the probe of circular ring type can be inserted in tumor tissues in annulus, be conducive to peel off out by complete from basis cranii nerve tumor, both avoid having produced post-operative complication, nervous tissue can have been exposed completely again, can assist the effective resolution target nerve of surgeon.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

Disposable use one pole probe, comprises handle 1 and probe 2, and the probe 3 of probe 2 is annular.Craniocerebral operations and operation on spinal cord run into tumor and are wrapped in around nervous tissue like this, cause nervous tissue when invisible, can be first peel off out by complete from basis cranii nerve tumor tissues with annular probe, use again certain stimulating current stimulation target nerve after nervous tissue is exposed to the open air completely.Assist surgeon rapidly and efficiently find target nerve, promoted surgical effect.

Claims (1)

1. disposable use one pole probe, comprises handle and probe, it is characterized in that: the probe of described probe is annular.
