Microporous syringe

The utility model discloses a micropore injection syringe, consisting of a needle, a medicine tube, a hydraulic cavity, a pressure releasing device. The hydraulic exertion enables a compression spring to generate elastic force, after the medicine is absorbed in the injection syringe, a spring driver is pressed to push a hydraulic piston to move forward, and to drive the injecting piston connected with the connecting rod to inject the medicine in the medicine tube into the nidus position of the patient through the needle rod and the needle. The structure of the utility model is simple, and the operation is easy. When being injected, no pain is felt by the patient, to effectively avoid the subcutaneous tissue to be damaged. The utility model is suitable for the injection of various medical fluids, distributes medical fluid to the target tissue more evenly, and shortens the onset time of medicine diffusion, in particular, to polycystic pathological tissue (Endometriosis). Because the multiple hole injecting needle has more medicine delivery points at one time, the original fussy operation of injecting to each cyst repeatedly is changed, providing great convenience to both doctors and patients.
