The present application relates to an ultra-fine endoscopic surgical forceps, which comprises a forceps core assembly, a forceps rod assembly, a connecting nut, a front handle, a rear connector of a pull rod, a rear handle, and a handle screw. The forceps core assembly is sleeved on the forceps rod assembly, and the forceps core assembly and the forceps rod assembly are fixed connected. The pull rod of the forceps core assembly is fixed through the forceps rod assembly and the back connector of the pull rod, and the back connector of the pull rod The front handle and the rear handle are hinged by the handle screw, and the connecting nut is sleeved in the clamp rod assembly and fixed with the front handle. The clamp core assembly is connected with the vice pin hole of the upper clamp head and the vice pin hole of the lower clamp head through the vice pin shaft of the two connecting pieces respectively. The front end of the front joint of the pull rod is hinged with the two connecting pieces through the tie rod pin hole of the two connecting pieces, and the front and rear joints of the pull rod rod are hinged with the two connecting pieces. The end is fixedly connected with the tie rod. Compared with the existing technology, the application has the following advantages and effects: simple structure, good strength, low assembly cost, convenient use, good stability, and safer endoscopic surgery.
【技术实现步骤摘要】
一种超细内窥镜手术钳
本申请涉及一种超细内窥镜手术钳,其最小外径可以达到1.2毫米,主要适用于医疗器械中的内窥镜手术器械。
技术介绍
现有产品没有超细内窥镜手术钳,在现有技术基础上直接缩小尺寸会导致结构不稳定,使用寿命短,整体结构不够牢固可靠,影响医疗器械的正常应用。
技术实现思路
本申请解决的技术问题是克服现有技术中存在的上述不足,而提供一种结构简洁,使用方便,成本低,稳定性好的超细内窥镜手术钳。本申请解决上述技术问题所采用的技术方案是:一种超细内窥镜手术钳,包括钳芯组件、钳杆组件、连接螺母、前手柄、拉杆后接头、后手柄、手柄螺钉,钳芯组件套装在钳杆组件上,钳芯组件、钳杆组件固定连接,钳芯组件的拉杆穿过钳杆组件与拉杆后接头固定连接,拉杆后接头穿过前手柄与后手柄连接,前手柄、后手柄通过手柄螺钉铰接,连接螺母套装在钳杆组件上并与前手柄固定连接,其特征是所述钳芯组件通过两个连接片的副销轴分别连接上钳头副销孔、下钳头副销孔,拉杆前接头前端通过拉杆销穿过两个连接片的拉杆销孔与两个连接片铰接,拉杆前接头后端与拉杆固定连接。本申请所述钳芯组件通过主销钉铆接在钳杆组件的支撑架上。本申请所述钳杆组件还设置有钳杆、保护弹簧、限位环,钳杆与支撑架焊接,保护弹簧套装在钳杆上,钳杆、保护弹簧均与限位环焊接。本申请所述连接片呈一端大一端小的腰形,副销轴位于连接片小的一端,拉杆销孔位于连接片大的一端,一方面保证拉杆销孔附近连接片的强度比较好,另一方面副销轴上下方向有位移,做得比较小有利于在不影响强度的情况下减小本申请体积和成本。本申请与现有技术相比,具有以下优点和效果:结构简洁,副销轴与连 ...
