技术领域technical field
本实用新型涉及医疗器械技术领域，具体涉及一种腔镜下静脉采血针套件。The utility model relates to the technical field of medical instruments, in particular to a venous blood collection needle set under an endoscope.
背景技术Background technique
在医疗领域中，医护人员通过各种手段采集、获取人体生理、病理信息，用于正确诊断疾病，在临床中对于血液标本的采集应用甚广的是静脉采血，可通过对血液学、血液内病原学及其他相关学科指标进行详尽的检测，一般多使用笔式或分体式静脉采血针。In the medical field, medical personnel collect and obtain human physiological and pathological information through various means to correctly diagnose diseases. In clinical practice, venous blood sampling is widely used in the collection of blood samples. Etiology and other related subject indicators are tested in detail, and pen-type or split-type venous blood collection needles are generally used.
静脉采血作为一种较为常见的采血方式，通常使用静脉采血针进行采血。目前现有技术中采血针通常使用的是头皮针，即采血针的夹持部为硬性材料，在进行腹腔内采血时，使用手术钳牵引采血针向前移动时，由于采血针采用的硬性夹持部，当采血针需要转向时，即与软管之间呈一定角度时，手术钳在夹持采血针时会出现掉针现象，不利于操作；另外现有技术的采血针依靠腔镜手术钳牵引通过trocar进入腹腔，手术钳与采血针互相挤压，通过性差，操作不方便，采血针针管裸露，容易与其他器械产生碰撞而损害针尖的锋利性。As a relatively common method of blood collection, venous blood collection usually uses a venous blood collection needle for blood collection. In the prior art, scalp needles are usually used for blood collection needles, that is, the clamping part of the blood collection needle is made of hard material. When the blood collection needle needs to turn around, that is, when it is at a certain angle with the flexible pipe, the surgical forceps will drop the needle when holding the blood collection needle, which is not conducive to operation; in addition, the blood collection needle of the prior art relies on laparoscopic surgery. The forceps traction enters the abdominal cavity through the trocar, and the surgical forceps and the blood collection needle squeeze each other, which has poor passability and is inconvenient to operate. The needle tube of the blood collection needle is exposed, and it is easy to collide with other instruments and damage the sharpness of the needle tip.
