Problems solved by technology

The establishment of this channel is generally based on the operator's feel and experience, and then tentatively drilled in 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

Embodiment 1

[0029] combine figure 1 and Figure 4 As shown, a screw channel pointing alarm device with a polygonal structure of the present invention is composed of a head body 1 and a handle 2 of a circuit breaker. The opener head body 1 is provided with four ribs 3 , and the head ends of the ribs 3 are electrodes 10 . Each edge 3 is uniformly distributed within a range of 360 degrees, and two pairs are equally spaced. A bare electrode 10 is provided on the top of each edge 3 , and the electrodes 10 provided on each edge 3 are insulated from each other.

[0030] figure 2 In the center of the top of the head and body part 1 of the shown opener, an electrode 10 may be provided, or may not be provided.

[0031] image 3 The top of the head body 1 of the shown opener is in the middle, and no electrode 10 is provided.

[0032] The electrodes 10 provided on each edge 3 of the opener head body 1 are connected to the handle 2 through a conductive material, and are covered with an insulatin...

Embodiment 2

[0043] The device of the invention can be used to establish a screw implantation channel for fixing instruments during clinical operations.

[0044] When the screw channel pointing alarm device with multi-edge structure provided by the present invention is used, take vertebral body surgery as an example:

[0045]The operator inserts the head and body part 1 of the device of the present invention into the patient's pedicle according to the running direction of the pedicle. The device of the present invention can detect the head and body part through the power supply control circuit module 7, the current measurement module 8 and the calculation processing module 9. 1. The current situation in each electrode circuit. This current situation reflects the position change of this edge 3 electrode 10 relative to other edge 3 electrodes 10. When a certain edge 3 electrode 10 approaches or enters the bone cortex, the electrode 10 here and other edges 3 electrodes 10 The biological resis...

Abstract

The invention provides a screw channel pointing alarm device with multi-edge structure and its application, which is composed of a circuit breaker head body (1) and a handle (2). The opener head body (1) is provided with 1-16 ribs (3), and each rib (3) is evenly distributed within a range of 360 degrees, and a bare electrode is arranged on the top of each rib (3). The opener head body (1) and the handle (2) are covered with an insulating layer. A power supply control circuit module (7), a current measurement module (8) and a calculation processing module (9) are arranged inside the handle (2). Each edge (3) corresponding to the rear part of the head and body (1) is provided with a warning light (5), 1 / string; the operator can adjust the surgical device to enter the bone according to the different current passing conditions of each edge. In the direction of the quality, the screw implantation channel for the fixed instrument is established. It can better guarantee the safety requirements of clinical operations and has great application value.

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...
