Description

Clamping device for operation Technical Field The application relates to the technical field of medical appliances, in particular to a clamping device for operation. Background In the operation of the throat of a human body, the throat tissues are often resected or repaired, and because the recurrent laryngeal nerves are relatively close in the operation area, nerve paralysis or injury can be caused by traction or direct contact in the process, so that the state of the recurrent laryngeal nerves needs to be concerned at any time. At present, in order to monitor recurrent laryngeal nerves in recurrent laryngeal nerve operation, an endotracheal tube with a recurrent laryngeal nerve electrode on the surface is inserted into a laryngeal tube, the recurrent laryngeal nerve electrode is in contact with a vocal cord, the recurrent laryngeal nerve electrode is connected to an external nerve monitor, a clamping device made of conductive metal is further electrically connected to the external nerve monitor through a wire, in actual use, the clamping device touches the recurrent laryngeal nerves, an external nerve monitor releases an electric signal, the recurrent laryngeal nerves are stimulated directly through the clamping device, the recurrent laryngeal nerves transmit electric stimulation, so that the vocal cord muscles generate myoelectric signals, the recurrent laryngeal nerve electrodes in contact with the vocal cords on the surface of the endotracheal tube receive the myoelectric signals, and then the recurrent laryngeal nerve electrodes receive and transmit the myoelectric signals to the nerve monitor, and a doctor can accurately judge whether the recurrent laryngeal nerves are damaged or not by analyzing waveforms, amplitudes and latency changes of the recurrent laryngeal nerve. In recurrent laryngeal nerve surgery, the clamping device is one of the surgical necessities, and the clamping device used in the traditional nerve monitoring mode is generally made of conductive metal, however, the density of the conductive metal is generally high, so that the manufactured clamping device is heavy and needs to go through a series of complicated process flows, and the process cost is relatively high. Disclosure of utility model In order to solve the problems of the clamping devices in the background art, the application provides a clamping device for operation. The application provides a surgical clamping device, which adopts the following technical scheme: The utility model provides a surgical clamping device, includes the clamping device body, the clamping device body is including clamping portion, control portion and handheld portion in proper order, the clamping portion is the setting of buckling, this internal conductive plastic that sets up of clamping device, clamping portion, control portion and handheld portion surface all are provided with insulating coating, the clamping portion tip is provided with the transfer portion that is used for conveying the electrical signal, be provided with the electrical signal receiving mouth that is used for connecting nerve detector in the handheld portion, the clamping device body is still including setting up at the inside additional strengthening of conductive plastic. By adopting the technical scheme, the surgical clamping device not only can effectively lighten the weight and reduce the burden of doctors in operation, but also simplifies the manufacturing process and reduces the production cost through the design of conductive plastics.
