Description

a spinal tap

technical field

The utility model relates to the technical field of medical appliances, in particular to a spinal puncture device.

Background technique

CN201822073611.5 discloses an orthopedic spinal puncture device. 1. The orthopedic spinal puncture device of the present utility model is easy to operate, can realize precise positioning and automatic puncture, and can be used as a new type of puncture tool for clinical promotion It has broad application prospects. 2. The puncture needle is used to push the power of the puncture needle to puncture through the trigger spring and return spring, which can achieve precise positioning, so that medical personnel do not need to provide puncture power by hand, because human tissues are peristaltic tissues, and the power provided by hands The puncture power is unstable, and precise positioning of the puncture cannot be achieved. 3. The trigger button is used to trigger the puncture needle body. When operating, you only need to move it with your fingers to trigger the puncture, thus realizing automatic puncture and easy operation. 4. The length of the puncture needle is 8-12cm, and the puncture needle under this length is designed according to clinical experience. It is beneficial for medical staff to control and avoid too deep or too shallow puncture during orthopedic spinal puncture. 5. The distal end of the puncture needle is equipped with a barb slice, which can accommodate more spinal puncture tissue through the barb slice, so as to obtain a large amount of specimen tissue to meet the needs of pathological research without repeated puncture. 6. The trigger spring is a double-layer spring structure, which is convenient to form a large trigger force, and can obtain a large release elastic force, and the speed is fast, which is conducive to moving the perfect spinal puncture specimen tissue.

But this orthopedic spinal puncture device still has the following defects that need to be improved; 1. When realizing automatic puncture, it is easy to puncture and stick off because of the fast puncture speed, which will cause harm to the patient's body; 2. The puncture needle is inconvenient to replace, reducing the practicality. To this end we propose a spinal tap.
