Description

Ultrasound puncture positioning device

Technical Field

The utility model relates to the technical field of positioning devices, in particular to a puncture positioning device for ultrasound.

Background Art

With the rapid development of the medical field, when a patient's internal bones are diseased or damaged, doctors in hospitals generally use ultrasonic puncture to insert a puncture needle into the human body to extract secretions for testing, or inject drugs into the body cavity. During the ultrasonic puncture process, a positioning device is usually used to assist doctors in the examination.

For example, in the prior art, the Chinese patent authorization number is CN202220583381.0, the application date is 2022-03-17, and the utility model patent of the puncture positioning device for ultrasound department is disclosed, which includes a handle; a lifting drive member is fixedly connected to the top of the handle, and a rectangular structured empty slot is provided in the middle of the handle. A lifting screw is rotatably connected to the handle through a bearing, and the upper end of the lifting screw is connected to a driven pulley through an interference fit; a fixed clamping block, the right end of which is movably connected to the handle; a movable clamping block, which is fixedly connected to the fixed clamping block through a threaded connector, which solves the problem that for the current traditional puncture equipment, when performing surgery, medical personnel hold an ultrasonic detection instrument in one hand and a puncture needle in the other hand to push the needle body into the patient's body. During the pushing process, the needle body should be kept straight into the patient's body. When the medical personnel are not proficient in operating the needle body during the pushing process, it is easy to cause the puncture needle to deviate, resulting in inaccurate sampling, and resampling is easy to cause the patient to suffer secondary pain.

However, the above patents still have the disadvantage that the height of the existing positioning device is mostly fixed. When the puncture needle pierces the patient's body, the positioning device will be suspended in the air. Since medical staff need to hold the puncture positioning device for a long time, it is easy to cause hand shaking and cause the puncture positioning position to shift, thereby affecting the accuracy of the detection;

Therefore, in order to solve this problem, the utility model proposes an ultrasonic puncture positioning device.
