Abstract

The utility model belongs to the technical field of propulsion plants of guiding needles for puncturing a body of human. The bone puncture needle gun comprises a gun body, a gun barrel which is integrated with the gun body, a guide cap integrated with the gun barrel in the front end of the gun barrel, a bolt whose front end penetrates into the gun barrel and back end extends out of the gun body in a chamber, an emission spring which is sleeved on the bolt in the chamber, a trigger which is hinged on the wall of the gun body in the gun body, and a reset spring which is sleeved on the back end of the gun body in the gun body. The bone puncture needle gun not only can accurately puncture into chosen puncture points without bending a bone puncture needle, but also can lighten the work intensity of medical staff, greatly increase the success ratio of the puncture, and alleviate the pain of patients and avoid unnecessary injury to patients, and does not damage the puncture needle.

Description

The bone puncture needle ejecting gun

Technical field

This utility model belongs to the technical field of propulsion plant of the guiding syringe needle of the health that punctures.

Background technology

In the process of the patient who suffers from some disease being diagnosed and treating, need carry out the bone puncture to the patient, but because the needle stand of bone puncture needle is less, when the hand-held Paracentesis needle holder of medical personnel carries out the bone puncture, tend to cause the bone puncture needle bending to misplace owing to firmly uneven, both influenced the success rate of puncture and damaged equipment, and returned the patient simultaneously and bring unnecessary painful and damage.

Summary of the invention

Little in order to overcome the bone puncture needle seat, medical personnel are hand-held to be not easy accurately to thrust in the selected point of puncture, cause damage and the problem that might damage equipment to the patient, this utility model provides a kind of bone puncture needle ejecting gun that can make medical personnel only once just bone puncture needle can be thrust accurately the site of puncture of wanting.

This bone puncture needle ejecting gun, comprise the rifle body, the gun barrel that is connected as a single entity with the rifle body, front end at gun barrel is provided with the guiding cap that is connected as a single entity with gun barrel, in bore, be provided with the rifle bolt that front end stretches in the gun barrel, the rifle body is stretched out in the rear end, in bore, be enclosed within the emission spring on the rifle bolt, in the rifle body, be hinged on the trigger on the rifle body wall, the plate fork that one end is connected as a single entity with trigger, another end yoke contacts with the emission spring on rifle bolt, in the rifle body, be enclosed within the return spring on the rifle bolt rear end, be hinged on the release link that contacts with rifle bolt with return spring on the rifle body inwall.

The beneficial effects of the utility model are: bone puncture needle is contained on the ejecting gun, bone puncture needle just can accurately thrust the position that needs puncture, and once success had both alleviated medical personnel's labor intensity, obviously improve the success rate of puncture again, also alleviated patient's the misery and the damage of equipment.
