Orthopedic joint hydrops extraction equipment

Abstract

The invention relates to extraction equipment, in particular to joint hydrops extraction equipment for the orthopedics department. According to the technical purpose, the joint hydrops extraction equipment for the orthopedics department can adjust the exposed length of a needle head according to the actual situation. According to the technical scheme, the joint hydrops extraction equipment for the orthopedics department comprises a rack, a holding rod, a needle cylinder, a needle head, a moving assembly and an extraction assembly, the rack is arranged at the top of the holding rod, the moving assembly is arranged on one side of the holding rod, the needle cylinder is placed on the moving assembly, the needle head is arranged on one side of the needle cylinder, and the needle head is in sliding fit with the rack; an extraction assembly is arranged on the side, away from the needle, of the rack. And when the clamping block moves rightwards, the clamping block moves towards the inner side at the same time, the clamping block can clamp the needle cylinder, in this way, the situation that when the pulling block is pulled to move, the needle cylinder is driven to move together can be avoided, and therefore hydrops can be better extracted.

Description

technical field [0001] The invention relates to an extraction device, in particular to an extraction device for orthopedic joint effusion. Background technique [0002] Joint effusion is usually caused by trauma, infection and various types of joint inflammation. The common symptoms are joint pain, swelling and mobility impairment. Generally, joint activities are restricted, drug treatment and arthrocentesis are given. Orthopedics is a department that mainly studies skeletal muscles. Therefore, when there is effusion in the joint that needs to be extracted, it is often done by the orthopedic department. During puncture treatment, the needle is usually inserted into the joint, and then the effusion is extracted. Nowadays, the needle is usually directly inserted into the joint by hand. At the joints, the needles are long and usually cannot be fully inserted directly. Then, when the needle barrel is manually held, it is difficult to control the amount of needle insertion, and t...

Problems solved by technology

[0004] In order to overcome the disadvantages that it is difficult to control the amount of insertion of the needle when the needle is held manually, and the connection between the needle and the skin is only a dot, so that shaking is very easy to occur when the hand is unstable, causing the needle to cause damage to the bone. The technical problem is: to provide an orthopedic joint effusion extraction device that can adjust the exposed length of the needle according to the actual situation
