本发明属于医用材料制备领域，特别涉及一种疝修补针。The invention belongs to the field of medical material preparation, in particular to a hernia repair needle.
背景技术Background technique
疝气是一种多发性疾病，尤其是儿童和中老年人群中患有疝气的比例较大，根据有关资料显示，全球每年大约有两千万的腹股沟疝气患者。疝气一般发生率为1-4%，在中国老年人口超过3亿，60岁以上人口疝气的发病率为2%，因此目前国内有上百万疝气患者。疝气轻者在局部有肿块，偶有疼痛，重者伴有腹部绞痛、恶心、呕吐、便秘、腹胀等症状，如不及时处理，部分突出的小肠将由于停止血运而坏死，严重者导致感染，威胁生命。目前治疗疝气主要采用手术缝合的方法，微创疗法因创口小患者康复速度快逐步得到普及，目前较为先进的设备有套管结构的手术针，也有手术钳结构的设备，套管结构的手术针针体较粗，并且制造成本高，手术钳本身粗大造成患者伤口较大，目前没有针对疝修补手术方便使用的手术补针。Hernia is a multiple disease, especially among children and middle-aged and elderly people who suffer from hernia. According to relevant data, there are about 20 million patients with inguinal hernia every year in the world. The general incidence of hernia is 1-4%. In China, the elderly population exceeds 300 million, and the incidence of hernia in the population over 60 years old is 2%. Therefore, there are currently millions of hernia patients in China. Mild cases of hernia have local lumps and occasional pain, and severe cases are accompanied by symptoms such as abdominal cramps, nausea, vomiting, constipation, and abdominal distension. If not treated in time, part of the protruding small intestine will be necrotic due to stop of blood supply, and severe cases will cause infection, life threatening. At present, the method of surgical suture is mainly used in the treatment of hernia. Minimally invasive therapy is gradually popularized due to the fast recovery speed of patients with small wounds. At present, the more advanced equipment includes surgical needles with sleeve structure, and there are also equipment with surgical forceps structure, and surgical needles with sleeve structure. The needle body is relatively thick, and the manufacturing cost is high. The surgical forceps itself is thick and causes the patient's wound to be large. At present, there is no convenient surgical supplementary needle for hernia repair surgery.
为此，开发一种便于临床应用并且减小患者伤口的疝修补针将会减轻患者的痛苦和减轻手术医生的工作量。For this reason, developing a hernia repair needle that is convenient for clinical application and reduces the patient's wound will reduce the pain of the patient and the workload of the surgeon.
发明内容Contents of the invention
