The utility model relates to the field of medical devices, in particular to a guide sheath which is convenient for fixing. The guide sheath convenient for fixation includes a sheath tube, an expansion tube and a support device, the sheath tube is a hollow structure, the expansion tube penetrates from one end of the sheath tube and penetrates from the other end of the sheath tube, the support device is sleeved on the sheath tube, and is slidably connected with the sheath tube; the support device includes a silica gel pad, a ferrule, a screw rod, a support foot and a connecting tube with an internal thread The silica gel pad sleeve is arranged on the outer surface of the sheath tube and is slidably connected with the sheath tube, wherein the silica gel pad is annular, and a groove is arranged in the middle, the groove is sleeved with a metal ring, and the ferrule ring is rotationally connected with the metal ring. Compared with the prior art, the utility model is more suitable for a wide range of people, and a sterile adhesive film is adhered on the surface of the sheath, which ensures the cleanness and hygiene of the ureteral guide sheath, avoids infection caused by penetration into the urethra of the patient, and does not need to be disinfected in advance.
【技术实现步骤摘要】
便于固定的导引鞘
本技术涉及医疗器械领域,尤其涉及一种便于固定的导引鞘。
技术介绍
临床上,人体在输尿管梗阻或发生结石时,需通过手术操作进行治疗,而在手术时需要建立手术通道,通过手术通道导入器械或其他操作,以方便进行手术,经常采用的手段为输尿管导引鞘配合输尿管软镜,输尿管导引鞘经尿道口置入,经膀胱、输尿管路径置管,从而建立输尿管软镜的工作通道。在插入输尿管导引鞘时,鞘管在扩张器的引导下一起插入输尿管,然而,现有的输尿管导引鞘难以固定,在手术过程中不易紧固以致晃动,不仅操作不便,影响手术进程,而且会在手术医生精神高度集中的情况下带来干扰,分散注意力,易发生操作失误。同时目前输尿管导引鞘置入输尿管时,通常是医生凭手感插入肾盂,有可能损伤输尿管及肾脏,严重的可以造成输尿管穿孔甚至断裂。
技术实现思路
鉴于现有技术中存在的技术问题,本技术提供了一种便于固定的导引鞘,方便固定输尿管导引鞘的位置,不易晃动,降低了对医生的干扰,使手术进程更为顺利。为实现上述技术目的,本技术采用的技术方案如下:便于固定的导引鞘,包括鞘管、扩张管和支撑装置,所述鞘管为中空结构,所述扩张管从所述鞘管一端穿入并由所述鞘管另一端穿出,所述支撑装置套设在所述鞘管上,并与所述鞘管滑动连接。所述支撑装置包括硅胶垫、套环、螺杆、支脚和设有内螺纹的连接管。所述硅胶垫套设在所述鞘管外表面并与所述鞘管滑动连接,其中所述硅胶垫呈环形,并在中部开设有凹槽,所述凹槽内套设有金属环,所述套环与所述金属环转动连接,所述连接管设于所述套环底部并与所述套环 ...
