Problems solved by technology

[0004] where blood vessels can be damaged by excessive pressure when pump devices are used
In addition, pump devices connected to blood vessels are bulky and expensive
[0005] In the case of a syringe, when the practitioner releases the plunger of the syringe after aspirating the thrombus, the plunger is sucked into the barrel by the pressure differential, thus potentially causing medical errors

Abstract

The present invention may provide a medical syringe comprising a cylinder including a stopper protruding inward; and a plunger disposed inside the cylinder so as to move back and forth in a first direction, wherein the plunger includes a plurality of protrusions, and the plurality of protrusions are arranged at intervals along the longitudinal direction of the plunger, and based on the first direction, any one of the stopper or the plurality of protrusions is arranged so as to be selectively overlapped according to the rotation of the plunger.

Description

Technical field [0001] Embodiments relate to a medical syringe. Background technique [0002] The field of angiography is one of the medical fields of vascular-related diseases by inserting micro-syringe needles such as insertion of blood vessels. In particular, when the thrombosis accumulates in the blood vessel, there can be dangerous and severe diseases, such as stroke, arteriosclerosis, and the like. Therefore, the thrombus in the blood vessel is one of the important medical surgery. [0003] Among them, in addition to the method of removing the thrombus by thrombolytic, there is a mechanical method that directly inserts the device in the presence of a thrombus and pulverizes the thrombus. The thrombosis can be removed by pulverizing or suction by using a syringe or pump device to form a negative pressure or positive pressure in the blood vessel. [0004] Among them, when the pump device is used, the blood vessel may be damaged due to excessive pressure. In addition, the pump...
