本实用新型属于医疗器械技术领域，尤其涉及一种连发止血夹装置。The utility model belongs to the technical field of medical equipment, and in particular relates to a continuous-fire hemostatic clip device.
背景技术Background Art
止血夹是一种医疗器械，止血夹与内镜配合使用，通常用于控制出血，材质通常由金属制成。止血夹是常用的一种在内镜下进行止血操作的方法，不仅行之有效，而且能够观察病变的具体情况。利用止血夹的机械力作用，将组织伤口夹住，使组织伤口闭合，起到止血作用，数日后，伤口愈合，夹头脱落沿消化道排出体外。内镜止血夹的机械止血只引起伤口周围黏膜最小限度的损伤，可以直接夹闭肉眼可见的出血性组织和病灶，尤其适用于小动脉破裂出血。A hemostatic clip is a medical device that is used in conjunction with an endoscope and is usually used to control bleeding. It is usually made of metal. Hemostatic clips are a commonly used method for hemostasis under endoscopy. They are not only effective, but also able to observe the specific conditions of the lesion. The mechanical force of the hemostatic clip is used to clamp the tissue wound, closing the tissue wound and playing a hemostatic role. After a few days, the wound heals and the clip falls off and is discharged from the body along the digestive tract. The mechanical hemostasis of the endoscopic hemostatic clip only causes minimal damage to the mucosa around the wound, and can directly clamp visible bleeding tissue and lesions, especially suitable for ruptured arteries and bleeding.
目前各种止血夹产品的主要用途有：1.提供内镜标记；2.适用于手术内镜下黏膜剥离术(ESD),内镜下黏膜切除术(EMR)经口内镜下肌切除术(POEM)等；3.将空肠司管固定在小肠壁上；4.作为一种辅助治疗方案，对保守治疗的20mm的胃肠道内腔穿孔进行闭合处理等。At present, the main uses of various hemostatic clip products are: 1. Providing endoscopic markings; 2. Suitable for surgical endoscopic mucosal dissection (ESD), endoscopic mucosal resection (EMR), per oral endoscopic myectomy (POEM), etc.; 3. Fixing the jejunal tube to the small intestine wall; 4. As an auxiliary treatment option, closing the 20mm gastrointestinal tract perforation treated conservatively, etc.
现有的连发操作的止血夹装置不能在使用的过程中对止血夹子进行反复开合或自由旋转，当进行上述操作时，止血夹对组织伤口的夹持位置不理想时,无法通过开合或旋转止血夹子使止血夹子处于理想位置，导致止血效果不理想，妨碍手术的正常进行。因此，上述手术中存在缺点和不足亟待需要改进。The existing hemostatic clip device for continuous operation cannot repeatedly open and close or freely rotate the hemostatic clip during use. When the above operations are performed, if the clamping position of the hemostatic clip on the tissue wound is not ideal, the hemostatic clip cannot be opened and closed or rotated to put it in the ideal position, resulting in unsatisfactory hemostasis effect and hindering the normal operation. Therefore, there are shortcomings and deficiencies in the above operation that need to be improved urgently.

本实用新型工作过程如下：将位于外套管3首端的止血夹1打开，导丝4穿过其连接管12，将该止血夹1的夹片111送入限位管13内，再将其余的止血夹1依上述方法依次穿过导丝4。上述将止血夹1的夹片111送入限位管13内时，每个止血夹1上连接管12上的滑块设置均位于相应弹性挡舌1313的前侧，再将上述止血夹1依次从外套管3的尾端送入，最后将导丝4穿过内套管2并将内套管2插入外套管3的腔体内，完成了多个止血夹1的安装。The working process of the utility model is as follows: the hemostatic clip 1 located at the head end of the outer sleeve 3 is opened, the guide wire 4 passes through its connecting tube 12, the clip 111 of the hemostatic clip 1 is sent into the limiting tube 13, and then the remaining hemostatic clips 1 are sequentially passed through the guide wire 4 according to the above method. When the clip 111 of the hemostatic clip 1 is sent into the limiting tube 13, the slider on the connecting tube 12 of each hemostatic clip 1 is set at the front side of the corresponding elastic tongue 1313, and then the above hemostatic clips 1 are sequentially sent from the tail end of the outer sleeve 3, and finally the guide wire 4 passes through the inner sleeve 2 and the inner sleeve 2 is inserted into the cavity of the outer sleeve 3, and the installation of multiple hemostatic clips 1 is completed.
向前推动内套管2，内套管2将最前端的止血夹1顶出外套管3，夹头11上的两个夹片111张开，当最前端的止血夹1的限位管13挤开外套管3的收缩部31向前移动，当限位管13上的卡环132运动到收缩部31时，收缩部31将限位管13上的卡环132限位卡紧，向后拉动导丝4，导丝4的推拉头41越过弹性卡舌123进入容纳腔124，推拉头41与容纳腔124紧配合；此时旋转导丝4可以同步旋转该夹头11的转动方向；导丝4前后移动，还可带动连接管12在滑槽1311的前后滑动，即夹头11的前后同步移动，从而实现夹头11的反复开合。The inner sleeve 2 is pushed forward, and the inner sleeve 2 pushes the frontmost hemostatic clip 1 out of the outer sleeve 3, and the two clips 111 on the chuck 11 are opened. When the limiting tube 13 of the frontmost hemostatic clip 1 squeezes the contraction part 31 of the outer sleeve 3 and moves forward, when the clamping ring 132 on the limiting tube 13 moves to the contraction part 31, the contraction part 31 limits and clamps the clamping ring 132 on the limiting tube 13, and pulls the guide wire 4 backward. The push-pull head 41 of the guide wire 4 passes over the elastic tongue 123 and enters the accommodating cavity 124, and the push-pull head 41 is tightly matched with the accommodating cavity 124; at this time, the rotating guide wire 4 can synchronously rotate the rotation direction of the chuck 11; the guide wire 4 moves back and forth, and can also drive the connecting tube 12 to slide back and forth in the slide groove 1311, that is, the chuck 11 moves back and forth synchronously, thereby realizing the repeated opening and closing of the chuck 11.
转动导丝4可以同步360度旋转夹头11，以满足夹取人体出血组织的合适角度，当夹头11对准需要夹持的出血组织后，向后拉动导丝4，推拉头41可带动连接管12上的滑块1312越过弹性挡舌1313，滑块1312进入到锁紧腔1314内，此时弹性挡舌1313弹起，将滑块1312锁定在锁紧腔1314内，此时，夹头11上的两个夹持片1113对合，其上相互配合的啮合齿将人体的出血组织夹持；继续拉动导丝4，使导丝4的推拉头41将连接管12上的缩颈管121涨开并进入到限位管13内，向前推动内套管2，限位管13将外套管3涨开，最终将最前端的止血夹1完全顶出外套管3。The rotating guide wire 4 can synchronously rotate the chuck 11 360 degrees to meet the appropriate angle for clamping the bleeding tissue of the human body. When the chuck 11 is aligned with the bleeding tissue to be clamped, the guide wire 4 is pulled backward, and the push-pull head 41 can drive the slider 1312 on the connecting tube 12 to pass the elastic stop tongue 1313, and the slider 1312 enters the locking cavity 1314. At this time, the elastic stop tongue 1313 pops up and locks the slider 1312 in the locking cavity 1314. At this time, the two clamping pieces 1113 on the chuck 11 are aligned, and the meshing teeth thereon cooperate with each other to clamp the bleeding tissue of the human body; continue to pull the guide wire 4, so that the push-pull head 41 of the guide wire 4 will expand the necking tube 121 on the connecting tube 12 and enter the limiting tube 13, push the inner sleeve 2 forward, and the limiting tube 13 will expand the outer sleeve 3, and finally the front end of the hemostatic clip 1 is completely pushed out of the outer sleeve 3.
继续向前推动内套管2，第二个止血夹1的夹头11伸出外套管3，向后拉动导丝4，使推拉头41进入到连接管12内，余下的止血夹1如前所述重复操作即可。Continue to push the inner sleeve 2 forward, the clamp head 11 of the second hemostatic clip 1 extends out of the outer sleeve 3, pull the guide wire 4 backward, so that the push-pull head 41 enters the connecting tube 12, and repeat the operation for the remaining hemostatic clips 1 as described above.
