本发明涉及医疗器械设备领域，尤其是一种用于闭合皮肤穿刺点的皮肤穿刺点钉合器。The invention relates to the field of medical equipment, in particular to a skin puncture point stapler for closing a skin puncture point.
背景技术Background technique
血液透析是急慢性肾功能衰竭患者的肾脏替代治疗方法，动静脉内瘘是用于血液透析治疗的外科手术之一。动静脉内瘘术是将前臂靠近手腕部位的动脉和邻近的静脉作一缝合，使吻合后的静脉中流动着动脉血，形成一个动静脉内瘘。在实际操作时，透析针会穿透皮肤进入皮下通路血管中，在血液透析结束后需要拔出此针，皮肤表面留下一个穿刺洞眼（如2mm直径的洞眼），因透析针穿刺的血透通路血管是跟上肢桡动脉接通的浅表静脉，其内血流压力接近动脉压力，拔出透析针后会出现喷血现象，因此需要采取措施闭合穿刺点的洞眼。现有技术中通常采用压迫带压迫的方法止血，而压迫带通常无法控制松紧度，压迫全靠医疗经验，如果压迫过紧会导致透析通路急性闭塞，发生并发症等危险，如果压迫不足会导致出血甚至皮下出血，难以实现愈合创口的治疗效果。而且压迫带的捆缚操作繁琐，不能在拔出透析针的同时完成，增加了喷血的风险。Hemodialysis is a renal replacement therapy for patients with acute and chronic renal failure, and arteriovenous fistula is one of the surgical procedures used for hemodialysis. Arteriovenous fistula is to suture the artery near the wrist of the forearm and the adjacent vein, so that arterial blood flows in the anastomotic vein, forming an arteriovenous fistula. In actual operation, the dialysis needle will penetrate the skin and enter the subcutaneous access blood vessel. After the end of hemodialysis, the needle needs to be pulled out, and a puncture hole (such as a 2mm diameter hole) will be left on the skin surface. The hemodialysis access vessel is a superficial vein connected to the radial artery of the upper extremity. The blood flow pressure in it is close to the arterial pressure. After the dialysis needle is pulled out, blood will spurt, so measures need to be taken to close the hole at the puncture point. In the prior art, the method of compressing the compression band is usually used to stop bleeding, but the tightness of the compression band is usually uncontrollable, and the compression depends entirely on medical experience. If the compression is too tight, it will cause acute occlusion of the dialysis access, and complications such as complications will occur. If the compression is insufficient, it will lead to Bleeding or even subcutaneous bleeding, it is difficult to achieve the therapeutic effect of wound healing. Moreover, the binding operation of the compression band is cumbersome and cannot be completed while pulling out the dialysis needle, which increases the risk of bleeding.

本发明在实施时，首先在置钉架5上安装闭合钉3，将闭合钉3嵌置在置钉架5内部。由于闭合钉3略小于置钉架5，且置钉架5整体的弧度大于半圆，因此闭合钉3固定在置钉架5内而不会发生脱落。初始状态时推钉脚9的前端向前抵靠在置钉架5的支脚6外侧，置钉架5的支脚6内侧包裹闭合钉3的钉脚7。When the present invention is implemented, at first the closing nail 3 is installed on the nail setting frame 5 , and the closing nail 3 is embedded in the nail setting frame 5 . Because the closure nail 3 is slightly smaller than the nail holder 5, and the overall arc of the nail holder 5 is greater than a semicircle, the closure nail 3 is fixed in the nail holder 5 without falling off. In the initial state, the front end of the push nail foot 9 leans forward against the outside of the leg 6 of the nail holder 5, and the inner side of the foot 6 of the nail holder 5 wraps the nail foot 7 of the closing nail 3.
工作时，使用者右手握持手持部2和推动杆12，左手握住透析针的针尾以固定透析针。确定好闭合钉3在皮肤上的位置后，使用者右手使用一定力度将闭合钉3下压贴紧皮肤，皮肤受压凹陷以避免拔针后出血。握紧手持部2和推动杆12，弹性夹片13压缩，推动杆12上端向前推动推钉件8，推钉脚9挤压置钉架5的支脚6，使支脚6发生轻度弯曲而向内收拢，同时支脚6挤压闭合钉3，使闭合钉3的钉脚7发生轻度弯曲而向内收拢，闭合钉3的四个钉脚7上的短刺14刺入皮肤起到固定作用，如同一个爪子向内抓取皮肤，使皮肤的穿刺点洞眼周围的组织被抓取在一起，然后使用者左手迅速拔针，拔针后因闭合钉3压迫在穿刺点上，穿刺点不会喷血。然后，使用者右手将推动杆12一握到底，类似于按压相机快门，使闭合钉3完全弯曲成形，固定在皮肤的穿刺点处。然后松开推动杆12，推钉件8因拉伸弹簧11的拉力向后移动，推动脚撤去对置钉架5的支脚6的挤压力，支脚6恢复到初始状态。而闭合钉3由于发生收拢变形，外形小于置钉架5的开口而从置钉架5内部脱离，被留在皮肤上。撤去闭合器，闭合钉3可持续保留，待患者下次透析时或者待穿刺点愈合后予以拆除，只需使用外科手术常用的拆钉器即可完成。When working, the user holds the handle 2 and the push rod 12 with his right hand, and holds the needle tail of the dialysis needle with his left hand to fix the dialysis needle. After confirming the position of the closure nail 3 on the skin, the user presses the closure nail 3 against the skin with a certain force with the right hand, and the skin is depressed under pressure to avoid bleeding after the needle is pulled out. Hold the handle part 2 and the push rod 12 tightly, the elastic clip 13 is compressed, the upper end of the push rod 12 pushes the push nail 8 forward, and the push nail foot 9 squeezes the leg 6 of the nail holder 5, so that the leg 6 is slightly bent and Fold inward, and at the same time, the legs 6 squeeze the closing nail 3, so that the nail feet 7 of the closing nail 3 are slightly bent and folded inward, and the short thorns 14 on the four nail feet 7 of the closing nail 3 penetrate into the skin to fix it The function is like a claw grabbing the skin inward, so that the tissues around the puncture point of the skin are grasped together, and then the user quickly pulls out the needle with his left hand. Will not squirt blood. Then, the user holds the push rod 12 to the bottom with his right hand, which is similar to pressing the shutter of a camera, so that the closure nail 3 is completely bent and shaped, and fixed at the puncture point of the skin. Unclamp push rod 12 then, push nail part 8 moves backward because of the pulling force of extension spring 11, promote pin and remove the extruding force of the supporting foot 6 of opposing nail frame 5, and supporting foot 6 returns to initial state. And closing nail 3 is because the deformation of gathering takes place, and profile is less than the opening of putting nail frame 5 and departs from putting nail frame 5 inside, is left on the skin. When the closer is removed, the closing nail 3 can be retained continuously, and will be removed when the patient undergoes dialysis next time or after the puncture point is healed, which can be completed by using a staple remover commonly used in surgical operations.
以上描述是对本发明的解释，不是对发明的限定，在不违背本发明精神的情况下，本发明可以作任何形式的修改。如推钉部1和手持部2的位置关系可以是相互垂直，也可以是成一定夹角相连。基于操作的舒适度和便捷性作出的改进，只要不脱离本申请的发明主旨，也在本申请的保护范围内。推动杆12的下端与手持部2之间还可以设置压缩弹簧，使推动杆12下端相对于手持部2张开一定夹角，便于人手握持施加推动力。The above description is an explanation of the present invention, not a limitation of the present invention, and the present invention can be modified in any form without violating the spirit of the present invention. For example, the positional relationship between the push nail part 1 and the handle part 2 may be perpendicular to each other, or may be connected at a certain angle. Improvements based on the comfort and convenience of operation are also within the protection scope of the present application as long as they do not deviate from the gist of the invention of the present application. A compression spring can also be arranged between the lower end of the push rod 12 and the handle 2, so that the lower end of the push rod 12 opens a certain angle with respect to the handle 2, so that it is convenient for people to hold and apply a driving force.
