Problems solved by technology

This method of operation has the following defects: 1. The doctor is injured by radiation; 2. The pressing finger is easy to move, the positioning is not accurate, and the puncture direction is difficult to grasp.
Many times rely on the doctor's experience, so repeated punctures often occur, and it is easy to puncture the trachea, esophagus, and blood vessels next to the cervical spine and cause other accidents
At the same time, because of the unevenness of finger pressure, it is difficult for patients to bear

Abstract

The invention provides a cervical intervertebral disc puncture locating guide device. The cervical intervertebral disc puncture locating guide device is mainly composed of a vertical rod (1), a crossrod (2) and an adjusting device (3), a fixing base (4) and a locking screw (5) are arranged at the lower end of the vertical rod (1), the adjusting device (3) is connected to the vertical rod (1) andis provided with a vertical adjusting button (7), a vertical locking bolt (6), a horizontal adjusting button (8) and a horizontal locking bolt (9), the cross rod (2) penetrates through the adjusting device (3) and is perpendicular to the vertical rod (1), and a rotary locating head (10) is fixedly connected to the top of the cross rod (2) and is provided with a puncture needle hole (11). Comparedwith the prior art, a doctor can be prevented from being exposed to X-rays for a long time, locating is accurate, the trachea, the gullet and the blood vessel can be effectively prevented from being punctured, the operating time of an operation is shortened, and harm to a patient is reduced.

Description

technical field [0001] The invention relates to a positioning guide for cervical intervertebral disc puncture, in particular to a device used in clinical medicine for positioning and guiding the puncture of the target cervical intervertebral disc under a C-arm X-ray machine, which can effectively prevent doctors from long Time exposure of the device to X-rays. Background technique [0002] With the development of human society, cervical spondylosis has become a common high incidence. There are more and more cases of cervical intervertebral disc herniation. Many seriously ill patients need puncture and other operations. Compress the side of the cervical spine with C-type X-ray machine for exposure and positioning, and the other hand for puncture, that is, exposure, positioning, and puncture at the same time. This mode of operation has the following defects: 1. The doctor is injured by radiation; 2. The pressing fingers are easy to move, and the depth of positioning is inaccu...
