Background technology

The cervical vertebra interventional therapy is a very effective treatment technology, and it is little, with strong points that it has damage, and the therapeutic effect outstanding feature is applied in the clinical position in recent years widely.Because interventional therapy carries out under the mediation of X ray video, so with regard to producing the infringement of a problem----X-radiation to human body, especially to doctor's (executing the patient) health affected.X ray is a kind of ionizing radiation, during the roentgen radiation x body, can cause the atom of material or the fracture that molecular ionization makes protein molecular chain interruption, ribonucleic acid or DNA (deoxyribonucleic acid), destroy some significant enzyme of substance metabolism etc., but even coup injury cellularity.Doctor (patient) is for safety, be punctured to diseased region accurately, just must under real-time X line perspective, carry out, this also just will inevitably be subjected to the radiation of low dose X-ray (medical perspective X ray is a low dose X-ray), and this year in year out low dose radiation has accumulative effect----to body injury and finally causes healthy severe impairment!

Occur in location and the piercing process because the doctor is subjected to X-radiation, position and just can effectively reduce with puncture collimation and avoid the doctor to be subjected to X-radiation so design the positioning mechanical device that punctures

Traditional piercing process: prepare (sterilization, pendulum position etc.) before a art; B opens X line fluoroscopic machine; C doctor's left hand is gently pressed the site of puncture, observes the x-ray tv screen and finds the pathological changes gap accurately, and the right hand is held puncture needle and punctured; D rotates the accuracy that X line machine 90 degree are observed the puncture needle position, determines that puncture puts in place; E closes X line fluoroscopic machine; F carries out interventional therapy; G extracts puncture needle and oppresses pinprick; H treats end.

From above-mentioned puncture for treating process, the doctor is subjected to X-radiation in the process most of the time of b-e, and what, difficulty or ease and doctor of the site of puncture proficiency level that punctures can have influence on the degree that the doctor is subjected to X-radiation.

The utility model content

This utility model provides a kind of and can avoid the doctor to be subjected to the radiating cervical vertebra puncture locator of X-ray in the operation process midium or long term.

A kind of cervical vertebra puncture locator comprises: snakelike arm, puncture needle fixation clamp, compressing cross bar, compressor, fixing mobile jib, firm banking, fixed transverse rod and oppress clip; Fixedly mobile jib is arranged on the firm banking, and is vertical state in the course of the work, and fixed transverse rod is arranged on fixedly on the mobile jib, can move up and down along fixing mobile jib, and can fix its vertical position by the slip positioner; Snakelike arm is arranged on fixedly on the mobile jib, and can adjust the position of its in the vertical direction; The puncture needle fixation clamp is arranged on the end of snakelike arm; The compressing cross bar is arranged on the fixed transverse rod, and can be adjusted at position on the fixed transverse rod by the compressing clip; The end of compressing cross bar is provided with compressor.
