Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the proximal end herein refers to the end close to the operator, and the distal end refers to the end away from the operator.

[0014] refer to figure 1 and 2 , the disposable catheter needle 1 includes a hollow flat needle body 2 , a needle seat 3 , a needle core 4 and a needle core handle 5 . The needle body 2 may have an outer sheath 6 on it. The needle body 2 has a central through hole 7 . The needle core 4 is pluggably fit in the central through hole 7 of the needle body 2 . The front end of the needle core 4 is flat, and after being inserted into the needle body 2, its front end will not protrude from the front end of the needle body 2. The needle holder 3 is in a shape suitable for being pinched by fingers, has outwardly protruding flanges 8 at its two ends, and has a notch 9 on the proximal flange 8 . The proximal end of the needle c...

Abstract

A clinical minimally-invasive intervening type medicine feeding medical device comprises a guiding catheter and a catheter connecting piece. The guiding catheter comprises a catheter body and a guiding wire. The far end of the catheter body is suitable for being implanted into a human body. The catheter connecting piece at least comprises a fixing fin and a connector which are connected in sequence from the far end to the near end. The fixing fin is provided with a fin pipe. The catheter body is inserted in from the far end of the fin pipe of the fixing fin and penetrates out from the near end of the connector. Accordingly, medicine injected from the near end of the catheter body can reach the far end of the catheter body, and then the medicine reaches a human part which needs injection. According to the intervening type medicine feeding medical device, interventional therapy can be carried out conveniently and easily, the medicine can directly reach a focus, local medicine is high in concentration, clinical effect is obviously improved, the device can be used for curing diseases such as all kinds of prostatitis and hematospermia (cystospermitis) and can also be used for seminiferous duct radiography, and accordingly diagnosis on seminiferous duct diseases can be made.

Description

technical field [0001] The invention relates to a minimally invasive interventional drug delivery device, in particular to an interventional drug delivery device for treating the vas deferens. Background technique [0002] Minimally invasive interventional therapy is a kind of 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 localize pathological conditions in the body. treat. Intervention therapy uses digital technology to expand the doctor's field of vision and extend the doctor's hands with the help of catheters and guide wires. [0003] At present, the interventional treatments commonly used in modern minimally invasive interventional diagnosis and treatment techniques mainly include transcatheter arterial chemoembolization and percutaneous ablation. Minimally invasive interventional diagno...
