本发明涉及一种医疗器械，特别涉及一种基于内窥镜的带连发金属夹的体内闭合装置。The invention relates to a medical device, in particular to an endoscope-based internal body closure device with continuous-fired metal clips.
背景技术Background technique
消化道出血发病率高，病情变化快，出血量较大者可因周围循环衰竭而危及生命。消化内镜是20世纪中期逐渐发展起来的一种诊疗方式，其中利用金属夹止血和闭合穿孔是目前使用较为广泛的技术。在内窥镜直视下使用金属夹夹闭出血部位，大大提高了消化道出血的安全性和治愈率。在闭合穿孔时，根据穿孔的大小决定使用金属夹的数量，通常对于小穿孔，使用几个金属夹可闭合穿孔。涉及大穿孔，则需要多个金属夹逐渐闭合。The incidence of gastrointestinal bleeding is high, and the condition changes rapidly. Those with a large amount of bleeding may be life-threatening due to peripheral circulatory failure. Digestive endoscopy is a diagnosis and treatment method gradually developed in the middle of the 20th century, among which the use of metal clips to stop bleeding and close perforation is currently the most widely used technology. Under the direct vision of the endoscope, metal clips are used to clamp the bleeding site, which greatly improves the safety and cure rate of gastrointestinal bleeding. When closing a perforation, the number of metal clips to be used depends on the size of the perforation. Usually, for small perforations, several metal clips can be used to close the perforation. When large piercings are involved, multiple metal clips are required to gradually close.
目前内窥镜用体内闭合装置采用挤压组织压迫血管的方式达到止血目的，临床应用中金属夹常常因为患者胃壁蠕动而滑脱，而且一次只能施放一枚金属夹，施放完成后需取出再装填，增加了再定位的难度，延长了手术时间。At present, internal closure devices for endoscopes use the method of squeezing tissue to compress blood vessels to achieve hemostasis. In clinical applications, metal clips often slip off due to the peristalsis of the patient's stomach wall, and only one metal clip can be applied at a time. After the application is completed, it needs to be taken out and refilled. , which increases the difficulty of repositioning and prolongs the operation time.

Referring to Fig. 7, the push seat 12 in the present invention is provided with a U-shaped socket 121, the U-shaped bottom of the metal clip can be inserted into the U-shaped socket, and is stopped by two wings. The two slender arms 134 of the metal clip 13 are curved inwardly, and can be bent towards each other under the action of external force. The two slender arms are bent at 90 degrees at the same time to close.
配合参见图5，本发明中的抓钳14由对称设置的两个钳体141和两个钳柄142构成，钳柄固定连接在钳体的后端。护套11的前部设有短轴111，钳柄142通过轴孔1421与短轴111可转动相连；钳柄142后端与拉丝5的一端相连，拉丝5的另一端与手柄相连，操作手柄拉动拉丝使钳柄沿护套的短轴转动，从而实现抓钳的闭合。钳体141设有左右两排钳齿1411、1412，中间设有槽沟1413，前端设有砧板1414，该砧板设有向内弯曲的弧形面，槽沟1413形成金属夹的通道，砧板1414形成使金属夹闭合的导引作用体。Referring to FIG. 5 , the pliers 14 in the present invention is composed of two pliers bodies 141 and two pliers handles 142 arranged symmetrically, and the pliers handles are fixedly connected to the rear ends of the pliers bodies. The front part of the sheath 11 is provided with a short shaft 111, and the pincer handle 142 is rotatably connected with the short shaft 111 through the shaft hole 1421; Pulling on the wire rotates the pliers handle along the short axis of the sheath, thereby closing the pliers. The pliers body 141 is provided with two rows of pliers teeth 1411, 1412 on the left and right, a groove 1413 is arranged in the middle, and an anvil 1414 is arranged at the front end. Forms the guiding body that closes the metal clip.
本发明的操作过程原理可结合附图说明如下：The operation process principle of the present invention can be described as follows in conjunction with accompanying drawing:
使用时，首先利用抓钳14抓取目标组织，此时两根拉丝5同步向后拉，带动抓钳14闭合。When in use, the grasping forceps 14 are first used to grasp the target tissue, and at this time, the two drawing wires 5 are pulled back synchronously to drive the grasping forceps 14 to close.
然后，从抓钳14内推出金属夹13，并完成闭合。具体的传递过程为，推丝4带动推座12，推座12带动最后一个金属夹，再依次带动到当前施放的金属夹。金属夹被从护套11内推出，此时抓钳14已夹取目标组织，金属夹13进入抓钳的槽沟1413内并刺入目标组织，最后抵住砧板1414，继续用力推推丝4，使前端金属夹13的细臂1411、1412沿砧板1414的弧形面弯曲闭合后完成施放。若抓钳抓取目标组织时效果不理想，可以使其张开后重新抓取，确认后再通过控制手柄3锁定抓钳，保证了抓取目标组织的准确性。Then, the metal clip 13 is pushed out from within the pliers 14 and the closure is completed. The specific transmission process is that the push wire 4 drives the push seat 12, and the push seat 12 drives the last metal clip, and then sequentially drives to the currently released metal clip. The metal clip is pushed out from the sheath 11. At this time, the grasping forceps 14 have clamped the target tissue. The metal clip 13 enters the groove 1413 of the grasping forceps and penetrates into the target tissue. Finally, it touches the cutting board 1414 and continues to push the wire firmly. 4. Make the thin arms 1411 and 1412 of the metal clip 13 at the front end bend and close along the arc surface of the cutting board 1414 to complete the application. If the effect of grasping forceps is not satisfactory when grasping the target tissue, it can be opened and grasped again, and then the grasping forceps can be locked through the control handle 3 after confirmation, so as to ensure the accuracy of grasping the target tissue.
本发明采用类似订书机的原理，因此可以达到连续施放多全金属夹的目的，且闭合效果可靠。此外，抓钳具备反复开闭的功能，弥补了目前内窥镜用金属夹仅能施放一枚金属夹、抓持力小的不足之处。The invention adopts the principle similar to a stapler, so it can achieve the purpose of continuously releasing multiple all-metal clips, and the closing effect is reliable. In addition, the grasping forceps has the function of opening and closing repeatedly, which makes up for the shortcomings of the current metal clips for endoscopes that can only release one metal clip and have a small gripping force.
