本发明涉及医疗器械技术领域,具体涉及一种锚钉输送器及人工腱索植入装置。The invention relates to the technical field of medical devices, in particular to an anchor conveyer and an artificial tendon implant device.
背景技术Background technique
在治疗二尖瓣反流(mitral regurgitation,MR)的修复手术中,传统外科手术创伤大、风险高,现在临床上对微创修复二尖瓣反流的手术有很大的需求。二尖瓣反流介入微创治疗技术具有创伤小、并发症少等优势。人工腱索植入是介入式二尖瓣修复术的一种,其手术原理是:将缝线经导管途径送入左心室,使得缝线的一端与二尖瓣瓣叶固定,缝线的另一端通过锚钉与左心室心肌壁或***肌连接,形成人工腱索。但目前还存在着以下技术问题:人工腱索植入所用到的锚钉功能单一,一般仅用于锚入心室壁或***肌,后续还需要导入额外的器械将人工腱索与锚钉锁紧,即使用现有的锚钉实施经导管途径腱索修复时,锚定、锁线、及切线分别需要相应的输送器或切断导管来执行,因此手术过程中需要更换及导入不同的器械,操作较复杂,需使用的器械数量较多,成本较高。In the treatment of mitral regurgitation (mitral regurgitation, MR) repair surgery, traditional surgical procedures are traumatic and high-risk. Nowadays, there is a great demand for minimally invasive mitral regurgitation surgery in clinical practice. Interventional minimally invasive treatment of mitral regurgitation has the advantages of less trauma and fewer complications. Artificial chordal implantation is a kind of interventional mitral valve repair. The operating principle is: the suture is fed into the left ventricle through the catheter, so that one end of the suture is fixed to the mitral valve leaflet, and the other suture One end is connected with the left ventricular myocardial wall or papillary muscle through an anchor to form an artificial chordae. However, there are still the following technical problems: the anchors used for artificial chordal implantation have a single function, and are generally only used to anchor the ventricular wall or papillary muscles. Later, additional instruments need to be introduced to lock the artificial chords and anchors. , That is, when the existing anchor is used for transcatheter chordal repair, the anchoring, locking, and cutting require corresponding conveyors or cutting catheters to perform respectively. Therefore, different instruments need to be replaced and introduced during the operation. It is more complicated, requires a large number of instruments, and the cost is high.

本实施例中锚钉1000的工作过程如下:如图21和图22所示,初始状态时,锁套1100套 装在锚定件1200与锁杆1300上,数个弹性子件1210和数个限位弹片及1220被压缩进锁套1100的内腔中,锁套1100的近端面与穿线孔1321边缘平齐,人工腱索3000可沿穿线孔1321穿过锁杆1320。The working process of the anchor 1000 in this embodiment is as follows: as shown in Figure 21 and Figure 22, in the initial state, the lock sleeve 1100 is sleeved on the anchor 1200 and the lock rod 1300, and several elastic sub-components 1210 and several limiters The position elastic piece and 1220 are compressed into the inner cavity of the lock sleeve 1100, the proximal surface of the lock sleeve 1100 is flush with the edge of the threading hole 1321, and the artificial tendon 3000 can pass through the lock rod 1320 along the threading hole 1321.
如图23和图24所示,驱动锁套1100相对锁杆1300沿轴向近端运动,此时锚定件1200上的弹性子件1210被逐渐释放并展开,实现锚定功能。人工腱索3000被挤压进锁套1100和锁杆1300之间的径向间隙中。锁套1100与锁杆1300之间间隙小于人工腱索3000直径,人工腱索3000受到锁杆1300与锁套1100挤压,三者实现过盈配合,人工腱索3000被锁紧。当锁套1100近端上的刃口1130与凸台1322相抵,刃口1130将人工腱索3000一端切断,此时限位弹片1220展开释放,锁套1100被限位在锁杆1300上,实现了锁紧人工腱索及切断多余人工腱索的功能。As shown in Figs. 23 and 24, the drive lock sleeve 1100 moves axially proximally relative to the lock rod 1300. At this time, the elastic sub-member 1210 on the anchor 1200 is gradually released and expanded to realize the anchoring function. The artificial tendon 3000 is squeezed into the radial gap between the lock sleeve 1100 and the lock rod 1300. The gap between the lock sleeve 1100 and the lock rod 1300 is smaller than the diameter of the artificial tendon 3000. The artificial tendon 3000 is squeezed by the lock rod 1300 and the lock sleeve 1100, and the three achieve an interference fit, and the artificial tendon 3000 is locked. When the cutting edge 1130 on the proximal end of the lock sleeve 1100 is against the boss 1322, the cutting edge 1130 cuts off one end of the artificial tendon 3000. At this time, the limiting spring 1220 is unfolded and released, and the locking sleeve 1100 is limited on the lock rod 1300. The function of locking artificial tendons and cutting off excess artificial tendons.
如图25至图28所示,当锚钉1000与输送器2000组装时,锚钉1000上锁扣位1120与输送器1000内管上锁扣2210上的扣件2211相互扣合,避位面1331与限位部2212相抵(如图25和图26所示)。通槽2215对齐穿线孔1321(如图28所示)。驱动推杆2300直到端面与凸台1330端面相抵。锚钉1000与推杆2300、内管2200组装后,此时固定前手柄2410,再驱动后手柄2420将内管2200、推杆2300及锚钉1000组成的整体收进外管2100内腔中,限位凸起2214滑进外管上的限位槽2114中。穿线孔1321一侧与限位槽2114贯通,另一侧与限位槽2113贯通,人工腱索300可顺利穿过锚钉1000。As shown in Figures 25-28, when the anchor 1000 is assembled with the conveyor 2000, the locking position 1120 on the anchor 1000 and the fastener 2211 on the locking 2210 on the inner tube of the conveyor 1000 are buckled with each other. 1331 conflicts with the limiting portion 2212 (as shown in Figure 25 and Figure 26). The through groove 2215 is aligned with the threading hole 1321 (as shown in FIG. 28). The push rod 2300 is driven until the end face abuts against the end face of the boss 1330. After the anchor 1000 is assembled with the push rod 2300 and the inner tube 2200, the front handle 2410 is fixed at this time, and then the rear handle 2420 is driven to receive the inner tube 2200, the push rod 2300 and the anchor 1000 into the inner cavity of the outer tube 2100. The limiting protrusion 2214 slides into the limiting groove 2114 on the outer tube. One side of the threading hole 1321 is penetrated with the limiting groove 2114, and the other side is penetrated with the limiting groove 2113, and the artificial tendon 300 can pass through the anchor 1000 smoothly.
本实施例提供的锚钉输送器2000的工作过程如下:The working process of the anchor conveyor 2000 provided in this embodiment is as follows:
如图29和图30所示,首先将人工腱索300穿过穿线孔1320并贯穿锚钉1000,然后将锚钉输送器2000沿人工腱索3000(在这之前,人工腱索3000已缝至瓣叶上,且人工腱索3000远离缝合点的一侧伸出体外)送至心室壁或***肌的位置,直到外管2100的护套2110的端面与组织相抵。As shown in Figure 29 and Figure 30, first pass the artificial tendon 300 through the threading hole 1320 and penetrate the anchor 1000, and then move the anchor conveyor 2000 along the artificial tendon 3000 (previously, the artificial tendon 3000 has been sewn to On the valve leaflet, the side of the artificial chordae 3000 protruding out of the body away from the suture point) is sent to the ventricular wall or the position of the papillary muscle until the end surface of the sheath 2110 of the outer tube 2100 abuts the tissue.
如图31和图32所示,保持前手柄2410不动,驱动后手柄2420整体沿轴向向远端移动,将锚钉1000推出外管2100(如图31所示的a方向),扎入组织内,护套2110起到保护周围组织及原生腱索的作用。As shown in Figure 31 and Figure 32, keep the front handle 2410 still, drive the entire rear handle 2420 to move distally along the axial direction, push the anchor 1000 out of the outer tube 2100 (a direction as shown in Figure 31), and insert it In the tissue, the sheath 2110 plays a role in protecting the surrounding tissue and the native tendon chordae.
如图33至图35所示,然后牵拉人工腱索3000调节人工腱索3000的长度至合适的尺寸,然后驱动内管驱动轮2460(如图33所示的b方向旋转驱动),带动内管2200向近端移动从而带动锁套1100后撤,锚钉1000上的弹性子件1210展开锚固在组织内,同时锁套1100将人工腱索3000与锚钉1000锁紧并切断一侧人工腱索3000,此过程中,推杆2300保持对锁杆1300端面的推顶作用,防止锁套1100带动锁杆1300及弹性子件1210脱离组织。As shown in Figures 33 to 35, the artificial tendon 3000 is then pulled to adjust the length of the artificial tendon 3000 to a suitable size, and then the inner tube driving wheel 2460 is driven (rotated in the direction b as shown in Figure 33) to drive the inner tube The tube 2200 moves proximally to drive the locking sleeve 1100 to withdraw. The elastic component 1210 on the anchor 1000 is deployed and anchored in the tissue. At the same time, the locking sleeve 1100 locks the artificial tendon 3000 and the anchor 1000 and cuts off one artificial tendon. Cable 3000. During this process, the push rod 2300 maintains the pushing effect on the end surface of the lock rod 1300 to prevent the lock sleeve 1100 from driving the lock rod 1300 and the elastic component 1210 from the tissue.
如图36和图37所示,最后,保持后手柄2420不动,沿轴向朝近端后撤前手柄2410(如图36所示的c方向),将锚钉1000上的锁扣位1120与锚钉输送器2000上的锁扣2210解锁,撤出锚钉输送器2000及多余人工腱索3000。As shown in Figure 36 and Figure 37, finally, keeping the rear handle 2420 still, retract the front handle 2410 proximally in the axial direction (direction c as shown in Figure 36), and lock the anchor 1000 on the lock position 1120 Unlock with the lock 2210 on the anchor conveyor 2000, and withdraw the anchor conveyor 2000 and the excess artificial tendon 3000.
