Description

腔镜用多相稳固适配腹壁穿刺器Laparoscopic multi-phase stable fit abdominal trocar 技术领域technical field
本发明涉及手术辅助装置，特别是腔镜用多相稳固适配腹壁穿刺器，它应用于腹腔镜手术中腹壁内外通道建立的。The invention relates to a surgical auxiliary device, in particular to a multi-phase stable fit abdominal wall puncture device for laparoscopic surgery, which is applied to the establishment of internal and external channels of the abdominal wall in laparoscopic surgery.
背景技术Background technique
腹腔镜手术是在腹壁置入腹壁穿刺器的鞘管建立手术通道，向腹腔内注入高压的气体膨胀腹腔，产生空间，并经过腹壁穿刺器的中空管状结构置入柱状腹腔镜观察腹腔内手术过程，利用长柄的手术器械通过腹壁穿刺器的中空管状结构进入腹腔手术操作。腹壁穿刺孔微小，又被称之为“钥匙孔”手术，因此与传统的开腹手术相比，患者腹壁手术损伤小，恢复快。显而易见，腹壁穿刺器是腹腔镜手术不可缺少的辅助装置。Laparoscopic surgery is to establish a surgical channel in the sheath tube of the abdominal wall puncture device, inject high-pressure gas into the abdominal cavity to inflate the abdominal cavity, create space, and place a cylindrical laparoscope through the hollow tubular structure of the abdominal wall puncture device to observe the intra-abdominal operation process. , using a long-handled surgical instrument to enter the abdominal cavity through the hollow tubular structure of the abdominal wall trocar. The abdominal wall puncture hole is very small, which is also called "key hole" surgery. Therefore, compared with traditional open surgery, the abdominal wall surgery for patients has less damage and quicker recovery. Obviously, the abdominal wall trocar is an indispensable auxiliary device for laparoscopic surgery.
腹壁穿刺器的主要结构为基座和鞘管，其中基座包含有三通管注气阀、阻气阀、以及后盖密封座等复杂结构，是构成腹壁穿刺器的主要结构，基座在术中始终保持在体外，不进入腹壁和腹腔；腹壁穿刺器的鞘管是一个管状结构，结构简单，术中进入腹壁和腹腔，根据鞘管的粗细不同，腹壁穿刺器可以分为3毫米，5毫米，10毫米，12毫米，15毫米等等不同的型号标准，鞘管越粗，则腹壁的创伤也越大，对于腹壁肥厚的肥胖患者，还需要鞘管加长的型号，因此腹壁穿刺器型号种类繁多，临床则根据病人的胖瘦、疾病的种类、手术过程中的随机应变而选择不同型号标准的腹壁穿刺器，由于目前腹壁穿刺器的基座和鞘管是一对一的一体化结构，为了满足临床对于不同型号鞘管的需求，往往需要配置多个型号的腹壁穿刺器，每个型号的腹壁穿刺器都是一个鞘管固定对应一个基座。但是即使如此，由于术中情况的不可预测，时常出现已经配置在手术台上的腹壁穿刺器要么缺乏实际需要的型号，造成手术困难，或增加病人的创伤，要么配置多余而无用，造成浪费。另外，腹腔镜用隔离防护袋的袋上硬质鞘管需要与腹壁穿刺器的基座连接配套使用，由于袋上硬质鞘管也存在粗细不同的多种型号，因此也面临同样的问题。The main structure of the abdominal wall trocar is the base and the sheath tube. The base includes the three-way tube gas injection valve, the air choke valve, and the back cover sealing seat and other complex structures. It is the main structure of the abdominal wall trocar. It is always kept outside the body and does not enter the abdominal wall and abdominal cavity; the sheath of the abdominal wall puncture device is a tubular structure with a simple structure, and it enters the abdominal wall and abdominal cavity during the operation. mm, 10 mm, 12 mm, 15 mm, etc. different model standards, the thicker the sheath, the greater the trauma to the abdominal wall. For obese patients with hypertrophic abdominal wall, a model with an extended sheath is required, so the abdominal wall puncture device model There are various types of abdominal wall trocars, and different types of standard abdominal wall trocars are selected according to the patient's fatness, type of disease, and adaptability during the operation. Since the base and sheath of the current abdominal wall trocar are one-to-one integrated structure, In order to meet the clinical requirements for different types of sheaths, it is often necessary to configure multiple types of abdominal wall trocars, and each type of abdominal wall trocar is a sheath fixed to a base. But even so, due to the unpredictability of intraoperative conditions, the abdominal wall trocars that have been deployed on the operating table often lack the actual required model, which makes the operation difficult, or increases the trauma of the patient, or the configuration is redundant and useless, resulting in waste. In addition, the rigid sheath tube on the bag of the isolation protective bag for laparoscopy needs to be used in conjunction with the base of the abdominal trocar. Since the rigid sheath tube on the bag also has various types of different thicknesses, it also faces the same problem.
不难理解，临床对于腹壁穿刺器的不同需求，是由于对其配套连接鞘管的不同需求，尝试采用一个通用的基座，可以任意连接腹腔镜术中需要的不同型号的鞘管，就能够降低成本，满足临床医生术中对腹壁穿刺器的不同需求。It is not difficult to understand that the different clinical requirements for abdominal wall trocars are due to the different requirements for their supporting connecting sheaths. Try to use a universal base, which can be arbitrarily connected to different types of sheaths required in laparoscopic surgery. Reduce costs and meet the different needs of clinicians for intraoperative abdominal trocars.
鉴于此，本发明将腹壁穿刺器的基座设置具有一个通用适配接口功能，每一种型号的鞘管设置具有一个通用适配插口功能，即粗、细、长、短不同型号的鞘管的一端均具有一个通用适配插口功能，换言之，一个型号的基座可以连接多种型号的鞘管，因此在术中医生可以按照临床需要随意连接所需型号的鞘管。另外，由于腹腔镜手术时腹腔内密闭隔离防护用的软质袋上连接有粗细不同的多个硬质鞘管，同样需要与之相匹配的多种型号的基座，本发明将腹壁穿刺器的基座转换设置具有一个通用适配接口功能，即可实现多种型号的鞘管连接一个型号的基座。In view of this, the present invention sets the base of the abdominal wall trocar to have a universal adapting interface function, and each type of sheath is set to have a universal adapting socket function, that is, thick, thin, long and short sheaths of different models Both ends have a universal adapter socket function, in other words, one type of base can be connected to multiple types of sheaths, so doctors can freely connect the required types of sheaths according to clinical needs during the operation. In addition, since a plurality of rigid sheath tubes with different thicknesses are connected to the soft bag for airtight isolation and protection in the abdominal cavity during laparoscopic surgery, various types of bases that match with it are also required. The pedestal conversion set of the 2000 has a universal adapter interface function, which can realize the connection of multiple models of sheaths to one model of pedestal.
由于鞘管在穿刺置入腹壁时遇到阻力，需要用力旋转才能穿刺进入腹腔，本发明研究在前期的实验中发现在腹壁穿刺时鞘管与基座的螺纹连接处非常容易旋转松动，影响手术操作，显然，腹壁穿刺使用时在鞘管与基座螺纹连接的部位是薄弱环节，需要加强稳固。Because the sheath encounters resistance when puncturing the abdominal wall, it needs to be rotated hard to puncture into the abdominal cavity. In the previous experiments of the present invention, it was found that the threaded connection between the sheath and the base is very easy to rotate and loosen during abdominal wall puncture, which affects the operation. Operation, obviously, when the abdominal wall puncture is used, the threaded connection between the sheath tube and the base is a weak link, which needs to be strengthened and stabilized.
目前不同粗细型号的腹壁穿刺器，均配置有相应的不同粗细型号的穿刺针芯，换言之，一个穿刺针芯只能与一种型号的鞘管配套使用，由于临床术中对多种型号的需要，一台手术往往需要多个穿刺针芯。At present, abdominal wall trocars of different thicknesses are equipped with corresponding puncture needles of different thicknesses. In other words, one puncture needle can only be used with one type of sheath. Due to the need for multiple models in clinical surgery , a surgery often requires multiple puncture needle cores.
由于临床广泛使用腹壁穿刺器，其中主要结构的穿刺针芯用量和基座的用量都非常巨大，而且使用后的医疗废物处理涉及到环保等问题，因此如能减少穿刺针芯用量和基座的用量，不仅具有重要的经济价值，还具有重要的社会价值。Because abdominal wall trocars are widely used in clinic, the amount of puncture needle core and base of the main structure are very large, and the disposal of medical waste after use involves environmental protection and other issues. Therefore, if it can reduce the amount of puncture needle core and the base Dosage not only has important economic value, but also has important social value.
