Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings.

[0008] The disposable monopolar probe includes a handle 1 and a probe 2, and the probe head 3 of the probe 2 is a circular ring. In this way, in craniocerebral surgery and spinal cord surgery, when the tumor is wrapped around the nerve tissue and the nerve tissue is not visible, a circular probe can be used to completely strip the tumor tissue from the nerve at the base of the skull, so that the nerve tissue is completely exposed. Then stimulate the target nerve with a certain stimulation current. It assists the surgeon to find the target nerve quickly and efficiently, and improves the surgical effect.

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

technical field [0001] The patent of the present invention belongs to the category of medical devices, specifically a single-use monopolar probe. Background technique [0002] Disposable probes are a common medical accessory used with neuromonitors. In surgery, it is first connected to the nerve monitor, and then inserted into the muscle controlled by the nerve to be probed. The stimulation current output by the nerve monitor is transmitted to the muscle tissue through the probe head of the probe. At present, the existing disposable probes, whose probe heads are cylindrical structures, are mostly used for routine low-risk operations such as thyroid and parotid glands. When the nerve tissue is wrapped and covered by the tumor, for example, using a common probe to peel off the tumor tissue, the cylindrical probe tip can easily cause the tumor tissue to rupture, resulting in various postoperative complications. SUMMARY OF THE INVENTION [0003] The technical problem to be s...
