Screw channel pointing alarm device of multi-edge structure and application thereof

Abstract

The invention provides a screw channel pointing alarm device of a multi-edge structure and application thereof. The screw channel pointing alarm device is composed of an open circuit head part (1) and a handle (2). The head of the open circuit head part (1) is provided with 1-16 edges (3). The edges (3) are evenly distributed within the 360-degree range. An exposed electrode is arranged at the top end of each edge (3). The open circuit head part (1) and the handle (2) are covered with an insulating layer. A power supply control circuit module (7), a current measuring module (8) and a computing and processing module (9) are arranged in the handle (2). Warning lamps (5) are arranged on all the edges (3) corresponding to the rear of the body of the head part (1), and one warning lamp exists in one string. An operator can adjust the direction, entering bone substances, of an operation device according to different current passing conditions of all the edges, and a screw implanting channel for a fixation instrument is established. The safety requirement of clinical operations can be well guaranteed, and high application value is achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a screw channel pointing alarm device with a polygonal structure and its application. Background technique [0002] At present, screws and other internal fixation devices 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. The establishment of the 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 leads to a high probability of screw misplacement. For example, screws are more likely to penetrate cortical bone, causing additional damage. In some complex anatomical parts, such as the spine and pelvis, the surrounding anatomical structures are complex and adjacent to the spinal co...
