技术领域technical field
本发明属于临床医学普通外科学技术领域，具体涉及一种无充气经口腔镜甲状腺手术用穿刺器。The invention belongs to the technical field of general surgery in clinical medicine, and in particular relates to a puncture device for non-inflatable transoral mirror thyroid surgery.
背景技术Background technique
传统腔镜甲状腺手术过程中，经常会因为使用超声手术刀、电凝钩等器械，产生手术烟雾，手术烟雾是由95%的水或水蒸气和5%颗粒形态存在的细胞碎片所组成，不仅会影响手术中视野的清晰，还会对手术室人员身体健康存在潜在的危害，现有技术中多采用CO2充气的方法，在维持手术空间的同时还能排出手术空间中的烟雾。但是，CO2充气有引起皮下气肿、纵膈气肿、高碳酸血症和二氧化碳栓塞等疾病的风险。并且，近来一项宫颈癌的研究报道，相对于腹部开放手术，腔镜宫颈癌手术预后差，分析原因，可能与CO2充气导致肿瘤播散有关。由此，采用无充气方法进行手术是更好的选择，但是由于手术难度较大，国内外鲜有报道。在腔镜甲状腺手术中，利用悬吊法也可以维持手术操作空间，该方法在手术过程中通过对颈前皮瓣悬吊建立皮下手术空间，能达到和CO2充气一样的空间维持效果能够有效避免术中充注CO2气体所引起的相关并发症。同样，无充气悬吊的方法也需要解决手术操作产生的烟雾问题，需要持续的抽气以排除烟雾，以保持手术视野清晰。但是，传统的腔镜手术穿刺器存在弊端，传统穿刺器直径较小，插入器械操作时，气体流通量受限，不利于顺利排出烟雾；其次传统穿刺器为了防止CO2气体外漏，在穿刺器底座都设置有防漏气装置，从而明显增粗了手术底座，经口腔镜甲状腺手术，由于操作空间小，传统穿刺器底座容易互相干扰，不利于手术操作。为了解决上述问题，对传统充气腔镜穿刺器进行改进。During traditional laparoscopic thyroid surgery, surgical smoke is often generated due to the use of ultrasonic scalpels, electrocoagulation hooks and other instruments. Surgical smoke is composed of 95% water or water vapor and 5% cell debris in the form of particles. Not only It will affect the clarity of the field of view during the operation, and there will be potential hazards to the health of the operating room personnel. In the prior art, the method of CO2 inflation is mostly used, and the smoke in the operation space can be discharged while maintaining the operation space. However, CO2 inflation has the risk of causing diseases such as subcutaneous emphysema, mediastinal emphysema, hypercapnia, and carbon dioxide embolism. Moreover, a recent study of cervical cancer reported that compared with open abdominal surgery, laparoscopic cervical cancer surgery has a poorer prognosis. The reason may be related to the spread of tumors caused by CO2 inflation. Therefore, it is a better choice to use the non-inflatable method for surgery, but due to the difficulty of the operation, there are few reports at home and abroad. In laparoscopic thyroid surgery, the surgical operation space can also be maintained by using the suspension method. This method establishes a subcutaneous surgical space by suspending the anterior neck flap during the operation, which can achieve the same space maintenance effect as CO2 inflation and can effectively avoid Related complications caused by intraoperative CO2 gas injection. Similarly, the method of non-inflatable suspension also needs to solve the problem of smoke generated by the surgical operation, and continuous suction is required to get rid of the smoke so as to keep the surgical field of view clear. However, the traditional trocar for laparoscopic surgery has disadvantages. The diameter of the traditional trocar is small, and the gas flow rate is limited when inserting the instrument, which is not conducive to the smooth discharge of smoke. Secondly, in order to prevent the leakage of CO2 gas, the traditional trocar The bases are equipped with anti-leakage devices, which significantly thicken the surgical base. Due to the small operating space, the bases of traditional trocars are easy to interfere with each other, which is not conducive to surgical operations. In order to solve the above problems, the traditional gas-filled endoscopic trocar is improved.
