The utility model discloses a laparoscopic instrument suction sleeve, which comprises a pipe body and a rotating part, the top end of the side wall of the pipe body is fixedly installed with an air extraction device, the right end of the pipe body is fixedly installed with a rubber ring, the outer wall of the rubber ring is provided with an inclined surface, the right end of the outer wall of the pipe body is screwed with a threaded ring, the outer wall of the threaded ring is connected with a top ring through the rotating part, and the top ring is located on the left side of the inclined surface, the utility model relates to a top ring The new type is provided with a rubber ring at the right end of the pipe body, the outer wall of the rubber ring is provided with an inclined surface, the outer wall of the pipe body is screwed with a threaded ring, and the outer wall of the threaded ring is provided with a top ring, which drives the top ring to move to the right through the rotation of the threaded ring. Because of the setting of the inclined surface, the wall thickness of the rubber ring is successively increased from left to right, then the top ring makes the inner wall of the rubber ring closely adhere to the laparoscopic instrument On the mechanical rod, the right end of the pipe body shall not be opened during air extraction, which will affect the extraction effect and ensure the sealing effect.
【技术实现步骤摘要】
腹腔镜器械吸引套管
本技术涉及吸引套管
,具体为腹腔镜器械吸引套管。
技术介绍
在进行腹腔手术时,通常会用到电凝和超声刀等能量平台,电凝和超声刀产生的水雾极易引起腹腔镜镜头模糊,为了消除水雾,市面上也出现了吸引套管,目前常见的套管的后端均由橡胶组成,进而增加密封效果,但是在进行套管内部抽气时,橡胶也容易开启,导致抽取效果较差,为此,我们提出腹腔镜器械吸引套管。
技术实现思路
本技术的目的在于提供腹腔镜器械吸引套管,以解决上述
技术介绍
中提出的问题。为实现上述目的,本技术提供如下技术方案:腹腔镜器械吸引套管,包括管体和转动件,所述管体的侧壁顶端固定安装有抽气装置,所述管体的右端固定安装有橡胶环,所述橡胶环的外侧壁设有斜面,所述管体的外侧壁右端螺接有螺纹环,所述螺纹环的外侧壁通过转动件连接有顶环,所述顶环位于斜面的左侧。优选的,所述转动件包括圆环,所述圆环的外侧壁固定安装在顶环的内侧壁左端,所述管体的外侧壁设有环槽,所述圆环的内侧壁滑动安装在环槽的内侧壁。优选的,所述顶环的内侧壁上下两端均固定安装有横杆,所述斜面的上下两端均设有滑道,两个所述横杆的右端分别位于两个所述滑道内。优选的,所述抽气装置包括立管,所述立管的底端和管体的侧壁顶端相固定,所述立管的内侧壁滑动安装有活塞,所述活塞的顶部固定安装有拉杆,所述立管的内侧壁底部固定安装有第一单向阀,所述立管的内侧壁右端一体成型有横管,所述横管内固定安装有第二单向阀。与现有技术相比,本技术的有益效果是:本技术通过在管体 ...
