specific Embodiment 1

[0061] In one embodiment, as figure 1 and Figure 2a As shown, a multi-point continuous positioning and anchoring implantation device 3 system includes a control handle 1, an anchoring device 2 connected to the control handle 1, and an implantation device 3 detachably connected to the distal end of the anchoring device 2 , the anchoring device 2 includes a delivery catheter 21, a positioning unit 22 arranged in the delivery catheter 21, and the positioning unit 22 includes a needle storage tube 223, an anchor 222 arranged in the needle storage tube 223 and a push rod 221. The anchor 222 is located at the distal end side of the push rod 221 and is partly or completely preinstalled inside the needle tube 223; the implantation instrument 3 system also includes a positioning guide 4, and the positioning guide 4 includes a positioning guide. Guide wire 41 and control part 42, the distal part of the positioning guide wire 41 forms a plurality of detachable connection points 5 on th...

specific Embodiment 2

[0072] In one embodiment, as Figure 9 shown. When the positioning guide wire 41 is one and the control member 42 is multiple, a positioning ring 52 corresponding to the threading hole 6 is provided on the positioning guide wire 41, and the positioning ring 52 Set in a U-shaped structure. The U-shaped ring passes through the threading hole 6 to form the detachable connection point 5, the number of the control parts 42 is equal to that of the U-shaped ring, and the plurality of control parts 42 pass through the U-shaped ring successively After that, the fixed connection is formed.

[0073] The difference from the foregoing embodiments is that when there is one positioning guide wire 41 and multiple control members 42, the detachable connection points are all formed by one positioning guide wire 41, so The plurality of control parts 42 correspondingly pass through the positioning ring 52 to form the detachable connection; during operation, the positioning guide button 11 is f...

specific Embodiment 3

[0075] The difference from the specific embodiment 1 is: as Figure 4e and 4f As shown, multiple sets of positioning units 22 are pre-installed in the delivery catheter 21, and the set of positioning units 22 corresponds to a detachable connection point 5; multiple sets of positioning units 22 are arranged side by side in the delivery catheter 21, when the The distal end of the delivery catheter 21 reaches the first detachable connection point 5 along the positioning guide wire 41, and after the positioning unit 22 corresponding to the first detachable connection point 5 is operated and the anchoring is completed, the control member 42 from the first detachable connection point 5; the distal part of the delivery catheter 21 is converted to the second detachable connection point 5 along the positioning guide wire 41, and the positioning operation corresponding to the second detachable connection unit 22 and complete the anchoring, the control member 42 breaks away from the sec...

Abstract

The invention belongs to the field of medical instruments, and relates to an implantation instrument system capable of realizing multi-point continuous positioning and anchoring, which comprises a control handle, an anchoring device connected with the control handle, and an implantation instrument detachably connected with the far end of the anchoring device, and the anchoring device comprises a conveying catheter and a positioning unit arranged in the conveying catheter; the implantation instrument system further comprises a positioning and guiding device, the positioning and guiding device comprises a positioning and guiding line and a control piece, and a plurality of detachable connecting points are formed on the implantation instrument through the control piece at the far end of the positioning and guiding line. According to the implantation instrument system capable of realizing multi-point continuous positioning and anchoring, the detachable connecting points are arranged in vitro in advance, positioning of different anchoring points is realized only by operating the positioning and guiding line and the movement of the control piece, and meanwhile, the anchoring device is guided to move; the implantation instrument is conveniently positioned, and the operation difficulty of the implantation instrument system is reduced, so that the operation time is shortened, and postoperative complications of a patient are reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to an implantation device system capable of multi-point continuous positioning and anchoring, in particular to an implantation device system capable of multi-point continuous positioning and anchoring for treating heart valve regurgitation. Background technique [0002] The anatomical structure of the mitral valve is complex, including leaflets, valve ring, chordae and papillary muscles, which play an important role in maintaining the function of the left and right ventricle respectively. Any disease that affects the structural integrity and normal function of the valve leaflets, valve ring, chordae, papillary muscle, and left ventricle may lead to severe mitral regurgitation (MR), which can cause left ventricular failure, pulmonary hypertension, and , atrial fibrillation, stroke and death. According to the latest epidemiological survey data of western developed countries such as t...
