技术领域technical field
本发明涉及医疗用具，具体涉及一种穿刺针。The invention relates to a medical appliance, in particular to a puncture needle.
背景技术Background technique
目前介入超声已经成为超声医学的一个重要分支，各种超声穿刺探头和附加在探头上的穿刺架是介入性超声学的工具。在超声介入过程中，各种超声穿刺探头和附加在探头上的体外穿刺架和腔内喘息家是介入性超声学的工具，这是在超声显像发展的基础上，为了进一步满足临床诊断和治疗的需要而发展起来的。在临床使用中，一般在超声探头上还安装有穿刺架，然后通过穿刺架固定穿刺针，通过穿刺针获取人体内的目标组织，或者将医疗药剂通过穿刺针注入病人体内。其主要作用是在实时超声的监视或引导下，完成各种活检、抽液、穿刺、造影、血管引流、注药输血、癌灶注药等操作，可以避免某些外科手术，且达到与外科手术相同的效果。At present, interventional ultrasound has become an important branch of ultrasound medicine. Various ultrasonic puncture probes and puncture racks attached to the probes are the tools of interventional ultrasound. In the process of ultrasonic intervention, various ultrasonic puncture probes and extracorporeal puncture racks attached to the probes and intracavitary breathers are tools for interventional ultrasound. developed in response to treatment needs. In clinical use, a puncture frame is generally installed on the ultrasonic probe, and then the puncture needle is fixed through the puncture frame, and the target tissue in the human body is obtained through the puncture needle, or medical agents are injected into the patient's body through the puncture needle. Its main function is to complete various operations such as biopsy, fluid extraction, puncture, angiography, vascular drainage, drug injection and blood transfusion, and cancer focus drug injection under the monitoring or guidance of real-time ultrasound, which can avoid certain surgical operations and achieve the same level as surgery. Same effect as surgery.
然而在患者的手术穿刺难度较大的情况下，尤其是对于手术经验相对缺乏的医务人员，初次穿刺可能无法达到手术靶点，需要再次调整穿刺位置以确保在精确的手术靶点进形手术，这样就需要调整穿刺路，这样的话，由于改变后的穿刺路径未注射麻醉药物，因此，会极大增加患者的痛苦，增加医务人员的手术压力，进而导致手术时间延长、手术风险增加，甚至影响手术效果。However, in the case of patients with difficult surgical puncture, especially for medical staff who are relatively inexperienced in surgery, the initial puncture may not reach the surgical target, and the puncture position needs to be adjusted again to ensure that the surgery is carried out at the precise surgical target. In this way, the puncture path needs to be adjusted. In this case, since the changed puncture path does not inject anesthesia, it will greatly increase the pain of the patient and increase the surgical pressure of the medical staff, which will lead to prolonged operation time, increased surgical risk, and even affect The effect of surgery.
另外，由于患者本身的血管问题，可能导致多次穿刺无法到达目标血管，这样也会增加患者的痛苦，同时增加医务人员的压力。In addition, due to the patient's own blood vessel problems, multiple punctures may fail to reach the target blood vessel, which will also increase the pain of the patient and increase the pressure on the medical staff.
