本实用新型涉及美容整形技术领域，特别的涉及一种具有预防栓塞作用的脂肪移植针。The utility model relates to the technical field of cosmetic surgery, in particular to a fat transplantation needle with the function of preventing embolism.
背景技术Background Art
目前，美容类医美手术等微整形逐渐走进大家的认知内，越来越多人接受微整形和美容修复手术，自体脂肪移植是美容外科的重要手术项目，手术过程中需要使用脂肪移植针将自体脂肪移植到需要整形的身体部位，在实际运用中，手术医生为减少栓塞风险，多采用肿胀麻醉(收缩血管)、退针注射、低压微量推注以及预先分离组织间隙等，以减少栓塞风险，现有的注脂针为减少穿刺进血管的风险多将钝头设计为钝头，但是现有的注脂针在进行自体脂肪移植后可能会出现脂肪栓塞，造成较为严重的并发症，可导致发生栓塞的组织器官缺血、坏死，其中眼底动脉栓塞可导致失明，脑动脉栓塞可引起偏瘫、肺动脉栓塞可引起呼吸衰竭等，甚至导致患者死亡，At present, cosmetic surgery and other micro-plastic surgeries are gradually becoming known to everyone, and more and more people are accepting micro-plastic surgery and cosmetic repair surgery. Autologous fat transplantation is an important surgical project in cosmetic surgery. During the operation, a fat transplantation needle is needed to transplant autologous fat to the part of the body that needs plastic surgery. In actual use, in order to reduce the risk of embolism, surgeons often use swelling anesthesia (constriction of blood vessels), needle withdrawal injection, low-pressure micro-push injection, and pre-separation of tissue gaps, etc. to reduce the risk of embolism. Existing fat injection needles are often designed with blunt heads to reduce the risk of puncture into blood vessels. However, existing fat injection needles may cause fat embolism after autologous fat transplantation, causing more serious complications, which may lead to ischemia and necrosis of embolic tissues and organs. Among them, retinal artery embolism can cause blindness, cerebral artery embolism can cause hemiplegia, pulmonary artery embolism can cause respiratory failure, etc., and even lead to death of patients.
因此，提出一种具有预防栓塞作用的脂肪移植针以解决上述问题。Therefore, a fat transplantation needle with embolism prevention function is proposed to solve the above problems.
