一种软镜导入装置A soft mirror introduction device

技术领域technical field

本实用新型涉及医疗器械技术领域，具体涉及软镜导入装置。The utility model relates to the technical field of medical instruments, in particular to a flexible mirror introduction device.

背景技术Background technique

随着微创手术的普及，头部可弯曲的各类软性镜在各类手术中使用，为患者减少痛苦。大多数软镜可以一步到位插到相应检查或手术位置，但输尿管软镜、膀胱软镜、肾盂软镜、肠道软镜、消化系统软镜等，还是会出现难以插入到体内预定位置的问题。例如，由于输尿管软镜、膀胱软镜、肾盂软镜等均需要由人体尿道口插入，而由于尿道的狭窄和敏感，必须经过多个步骤的操作才能将软镜放置到预定体内位置，这样增了医生的操作步骤，工作效率低，手术成本高，手术时间长，患者身心痛苦。With the popularization of minimally invasive surgery, various types of flexible endoscopes with flexible heads are used in various surgeries to reduce pain for patients. Most flexible scopes can be inserted into the corresponding examination or operation position in one step, but flexible ureteroscopes, flexible cystoscopes, flexible pyeloscopes, flexible intestinal scopes, flexible scopes of the digestive system, etc., still have problems that it is difficult to insert into the predetermined position in the body . For example, since flexible ureteroscopes, flexible cystoscopes, and flexible pyeloscopes all need to be inserted through the human urethral orifice, and due to the narrowness and sensitivity of the urethra, multiple steps must be taken before the flexible scope can be placed in a predetermined position in the body, which increases the number of The operation steps of the doctor are reduced, the work efficiency is low, the operation cost is high, the operation time is long, and the patient suffers both physically and mentally.

具体的，例如，现有的输尿管肾盂镜从人体尿道进入到体内需要多次重复操作才能将软镜放置到位：第一步将带镜头的输尿管硬镜从人体尿道插入通过通道找到预定位置，第二步将斑马导丝通过输尿管软硬镜的工作通道插入到肾盂位置(可以通过显示屏观察到)，第三步将输尿管硬镜退出，但斑马导丝保留在肾盂位置，待输尿管硬镜完全退出，第四步将带有细小圆头的输尿管导入鞘组件顺着斑马导丝推进到肾盂位置(这时没有镜头监视，属于盲插)，第五步将输尿管导入鞘组件内部的引导鞘拔出，同时将斑马导丝也拔出，将输尿管导入鞘保留在人体内，第六步将软镜顺着输尿管导入鞘插入到肾盂部位。这样大大增加了医生的操作步骤和患者机体收损伤的程度，手术时间长，操作复杂，工作效率低，手术稳定性和可靠性低，且手术器械繁多，手术成本高。Specifically, for example, the existing ureteroscope needs to be repeated many times to place the flexible scope in place from the human urethra into the body: the first step is to insert the rigid ureteroscope with lens from the human urethra through the channel to find the predetermined position, and the third step The second step is to insert the zebra guide wire into the renal pelvis through the working channel of the rigid ureteroscope (which can be observed on the display screen), and the third step is to withdraw the rigid ureteroscope, but the zebra guide wire remains in the renal pelvis until the rigid ureteroscope is completely Exit, the fourth step is to advance the ureteral introduction sheath assembly with the small round head along the zebra guide wire to the position of the renal pelvis (there is no camera monitoring at this time, it is a blind insertion), and the fifth step is to introduce the ureter into the sheath assembly. At the same time, the zebra guide wire is also pulled out, and the ureteral introduction sheath is kept in the human body. In the sixth step, the flexible scope is inserted into the renal pelvis along the ureteral introduction sheath. This greatly increases the doctor's operation steps and the degree of damage to the patient's body. The operation time is long, the operation is complicated, the work efficiency is low, the operation stability and reliability are low, and there are many surgical instruments and high operation costs.
