本实用新型涉及医疗器材技术领域，具体为一种胸腔镜穿刺装置。The utility model relates to the technical field of medical equipment, in particular to a thoracoscopic puncture device.
背景技术Background technique
越来越多的手术可以借助胸腔镜完成，外科医生首先需要使用胸腔镜穿刺器刺穿胸壁建立手术通道，然后才能经通道放入胸腔镜及操作钳完成后续手术。胸腔镜穿刺器主要由穿刺鞘和穿刺针组成。手术医生首先将穿刺针套上穿刺鞘，然后用一定的力度作用于穿刺器尾部，借助于穿刺针锋利的尖端刺破腹壁使整个穿刺器进入腹腔，然后拔出穿刺针留下穿刺鞘成为一个手术通道，但传统穿刺器存在以下问题：More and more operations can be done with the help of thoracoscope. The surgeon first needs to use a thoracoscopic trocar to pierce the chest wall to establish a surgical channel, and then can put the thoracoscope and operating forceps through the channel to complete the follow-up operation. The thoracoscopic trocar is mainly composed of a puncture sheath and a puncture needle. The surgeon first puts the puncture needle on the puncture sheath, and then applies a certain force to the tail of the puncture device. With the help of the sharp tip of the puncture needle, the abdominal wall is punctured to make the whole puncture device enter the abdominal cavity, and then the puncture needle is pulled out and the puncture sheath becomes a Surgical access, but traditional trocars have the following problems:
其一，由于病人皮肤弹性的差异、器械进出穿刺器次数等因素，在使用过程中，穿刺器极易滑脱，对患者造成二次伤害，且器械无法能够顺利地穿过穿刺套管进行手术，外界气体也容易通过切口进入患者皮下。First, due to factors such as the difference in the elasticity of the patient's skin and the number of times the instrument enters and exits the puncture device, the puncture device is very easy to slip off during use, causing secondary damage to the patient, and the instrument cannot smoothly pass through the puncture cannula for surgery. External air can also easily enter the patient's subcutaneous through the incision.
其二，在腹腔分流术操作中常常需要使用到电凝钩，胸腔镜下电凝钩电灼切除部分囊壁以免再次形成包裹性积液，切除除病变组织，并可以达到止血的目的；电凝钩电灼过程会产生烟雾，阻碍医生视野，而传统的穿刺器不具备排放烟雾的功能。Second, electrocoagulation hooks are often used in peritoneal shunt operations. Under thoracoscopy, the electrocoagulation hooks and electrocautery remove part of the cyst wall to avoid the formation of encapsulated effusion again, remove the diseased tissue, and achieve the purpose of hemostasis; Coagulation hook electrocautery will produce smoke, which obstructs the doctor's field of vision, and traditional trocars do not have the function of discharging smoke.
其三，电凝钩在使用的过程中需要根据需要调节位置，而传统的穿刺器不具备调节电凝钩的功能。Third, the position of the electrocoagulation hook needs to be adjusted according to needs during use, while the traditional trocar does not have the function of adjusting the electrocoagulation hook.
