Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a portable negative pressure extraction device for interventional surgery. Background technique [0002] Interventional therapy is a minimally invasive treatment using modern high-tech means, that is, under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments are introduced into the human body to diagnose and locally treat internal diseases. Interventional therapy uses digital technology to expand the doctor's field of vision. With the help of the catheter, the guide wire extends the doctor's hands. Its incision is only the size of a grain of rice. Medical treatment of diseases with poor curative effect, such as tumors, hemangioma, and various hemorrhages, etc., interventional surgery has gained widespread attention and application in the medical field due to its remarkable therapeutic effect. It connects the inter...

Problems solved by technology

Interventional therapy uses digital technology to expand the doctor's field of vision. With the help of catheters and guide wires, the doctor's hands are extended. Its incision is only the size of a grain of rice, and it can treat many diseases that could not be treated in the past and required surgical treatment or surgery without cutting human tissue. For diseases with poor efficacy of medical treatment, such as tumors, hemangiomas, and various bleedings, interventional surgery has gained wide attention and application in the medical field for its remarkable therapeutic effect. Aiming at the discharge of excess body fluids in patients, it is generally used in clinical practice. It is to connect the interventional catheter with the syringe, and pull the syringe piston to provide a negative pressure environment to realize the extraction of excess body fluid in the patient's body. The syringe is generally operated manually by the medical staff. Completed under the same pressure, the utility model patent with the publication number CN215023369U discloses a small-hole liposuction needle, comprising: a liposuction needle body, which is a hollow tube with a liposuction channel inside; seat, the needle seat is used to connect with the negative pressure extraction device, the needle seat is connected with one end of the liposuction needle body; The other end of the body is connected; the guide frame is used to bond on the human skin to guide the liposuction needle body passing through the guide hole of the guide frame; the spinning handle is fixed on the end of the liposuction needle body close to the needle seat, To drive the liposuction needle body to slide in the guide hole of the guide frame

Although the negative pressure extraction device adopted in the prior art can realize the extraction of fat, it still cannot realize automatic extraction and maintain the pressure stability of the extraction process, and cannot achieve a good extraction effect. The extraction device can effectively solve the above technical problems
