The utility model relates to a cystoscope operating device. The utility model solves the problems of unreasonable driving structure and high installation requirement of the cystoscope operator's pull rod in the prior art. The manipulator is composed of a mirror seat connected with the main body of a closed hole device. A lock hook sleeve is connected to the main body of the closed hole device. The pull rod is penetrated into the mirror seat. The pull rod is connected with the slide block in the mirror seat. The mirror seat is also arranged with a wheel moving before and after the driving slide. The runner is connected to the adjusting wheel through a rotating rod. The utility model has the advantage of adopting a structure matched with the sliding block by the runner, and the rotary wheel is rotated into a slide block before and after moving, so as to realize the pulling of the pull rod. Compared with the traditional structure with two helical gears, the utility model has the advantages of simpler structure, lower installation requirements and lower cost. The locking hook is installed by limiting position, and the installation accuracy is higher, and the locking effect is better.
【技术实现步骤摘要】
一种膀胱镜操作器
本技术涉及一种医疗器械,尤其涉及一种膀胱镜操作器。
技术介绍
人体尿道和膀胱的疾患较多,使用尿道膀胱镜来做检查、手术,因其直观、正确,并可永久留下动态记录等多项优点,被临床治疗所广泛采用。尿道膀胱镜一般由内窥镜、手术钳、操作器、镜桥、鞘套及闭孔器组成,操作器上设置有调节轮用来推动拉杆的位移,而一般操作器上都是通过设置两个斜齿轮转动来实现推动拉杆的位移,但这种结构安装要求高,安装也叫复杂。
技术实现思路
本技术主要解决了现有技术中膀胱镜操作器拉杆推动结构不合理、安装要求高的问题,提供了机构简单合理的膀胱镜操作器。本技术解决其技术问题所采用的技术方案是:一种膀胱镜操作器,包括与闭孔器主体连接的镜座,在闭孔器主体上连接有锁钩套,拉杆穿入在镜座内,所述拉杆在镜座内与滑块相连,镜座内还设置有驱动滑块前后移动的转轮,转轮通过转杆与调节轮相连。本技术采用转轮与滑块配合的结构,将转轮转动转换成滑块前后移动,从而实现拉杆的拉动。本技术相比传统采用两个斜齿轮转动的结构,结构更加简单,安装要求低,也降低了成本。作为上述方案的一种优选方案,所述滑块一侧上沿垂直方向设置有驱动槽,驱动槽上端在滑块上部开口,转轮设置在滑块一侧,在转轮上偏离中心处设置有驱动柱,所述驱动柱卡入在驱动槽内。本方案中通过转动转轮,转轮上的驱动柱发生位移,驱动柱卡在驱动槽内,从而推动滑块进行前后位移。该滑块与镜座之间设置有使滑块只进行前后位移运动的导向机构。作为上述方案的一种优选方案,镜座内设置有限位槽,所述滑动块下端位于在限位槽内。本方案限制滑动块前后移动的距离,使得拉杆在一定范围内移动。作为上 ...
