The utility model provides a endoscopic protective surgical cutter, which comprises a hollow outer needle tube, an inner tube core arranged inside the outer needle tube, a gripping part and a valve arranged on the gripping part. A tip is arranged on the end side of one end of the outer needle tube, the other end of the outer needle tube is fixedly connected with the gripping part, a cavity is arranged in the gripping part, a spring is arranged in the cavity, and the inner tube core is hollow In the tubular structure, one end of the inner tube core passes through the outer needle tube and is connected with the spring through the pin seat, and the other end of the inner tube core is a round head. When the spring is in the state of natural extension, the other end of the inner tube core extends out of the tip of the outer needle tube, and the side wall on the side of the inner tube core away from the spring is provided with a knife edge. When the spring is in the state of natural extension, the knife edge is exposed out of the tip. The utility model completely avoids the risk that the conventional incision knife will cut the back wall of the injured organ, and the direction of the incision knife is fixed, at the same time, the utility model has the function of stitching the abdominal wall, and the operation procedure is simplified.
【技术实现步骤摘要】
腔镜下保护型手术切开刀
本技术涉及医疗器械的
,更为具体地,涉及一种腔镜下保护型手术切开刀。
技术介绍
目前的腔镜下的胆道等切开刀是开腹手术切开刀的延伸。当它进入腹腔时刀位于手柄内,切开器官时按压手柄端头,切开刀伸出手柄,通过向下向前切开器官,切割完毕按压控制开关切开刀退回手柄内。该腔镜下的手术切开刀在手术时刀锋及刀尖部向下向前切开胆管等管腔性器官前壁时有切开损伤该器官后壁的风险,这给手术带来了潜在的风险和危害。万一发生,对病人有较大损伤,且不具有缝合功能。而常见的气腹针,见图1,其包括空心的外针管1、设置在外针管1内部的内管芯2、握持部3以及设置在握持部3上的阀门4,外针管1一端的端侧设置有用于穿刺的尖部5,外针管1的另一端与握持部3固定连接,握持部3内设置有空腔30,空腔30内设置有弹簧6,内管芯2的一端穿过外针管1通过销座8与弹簧6连接,内管芯2的另一端为圆头且不固定,在弹簧6处于自然伸长状态时,内管芯2的另一端伸出至外针管1的尖部5外,内管芯2的侧壁上设置有开孔20,该开孔20与空腔30和阀门4连通,该气腹针只能用于送气或抽取人体组织液,而不能用于切开器官。因此,需要开发一种防止在手术时发生切开空腔器官前壁时避免损伤其后壁的多功能保护型切开刀,提高手术的安全性,降低手术成本。
技术实现思路
鉴于上述问题,本技术的目的是提供一种腔镜下保护型手术切开刀,以解决现有技术的切开刀在手术时有切开损伤胆管等管腔性结构的器官的后壁风险的问题;且该切开刀刀刃的方向固定,具有缝合功能,同时可用于送气、抽取 ...
