A real-time monitoring device for nail track establishment with display resistance

Abstract

The invention provides a screw path establishment real-time monitoring device displaying resistance size. An open-circuit head is connected with an open-circuit handle through an open-circuit rod, the open-circuit head and the open-circuit rod form an open-circuit head body, a first electrode and a second electrode are arranged in the open-circuit head body in a spaced mode, one end of each electrode is exposed outside the corresponding surface, far away from the open-circuit handle, of the open-circuit head body, the first electrode is connected with the second electrode through a power supply control module circuit to form a detection circuit, a resistance measurement part is connected with the first electrode, the second electrode and a resistance size display part separately, and the resistance size display part displays the resistance size. According to the screw path establishment real-time monitoring device, the screw path establishment process can be monitored in real time, once a screw path is established wrongly, medical staff can be reminded to adjust, correct establishment of the screw path is guaranteed, surgical operation is convenient, screw misplacement is avoided, additional damage to patients is reduced, surgical safety is guaranteed, the surgical time is saved, and the device is suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to the technical field of nail track establishment devices, in particular to a nail track establishment real-time monitoring device that displays resistance. Background technique [0002] At present, internal fixation devices such as screws are widely used in medicine, and the safe implantation of screws is the key to the success of surgery. To ensure the safe implantation of screws, it is usually necessary to establish a channel for screw entry before implanting screws. [0003] The establishment of this channel is generally based on the operator's feel and experience, and then tentatively drilled in with reference to the general walking direction of the medical anatomical structure, which often leads to screw misplacement. For example, screws are more likely to penetrate cortical bone, causing additional damage. in some complex anatomical sites. Such as the spine, pelvis...
