Embodiment 1

[0063] This embodiment provides an anchoring device. refer to figure 1 , figure 2 and image 3 , figure 1 is a schematic structural view of the anchoring device in Embodiment 1 of the present invention, figure 2 and image 3 They are schematic structural diagrams of the proximal anchor 100 and the distal anchor 200 in the anchoring device in Embodiment 1 of the present invention. The anchoring device includes the proximal anchor 100, the distal anchor 200 and the connector 300. The end anchor 100 includes a contact surface 110 and a non-contact surface. The contact surface 110 is used to contact the tissue. The contact surface 110 includes at least one concave portion and / or at least one convex portion. The concave portion or the convex portion includes but is not limited to Groove, pattern, frosted surface, etc. The connecting part 300 includes a first connecting part and a second connecting part extending from one end of the first connecting part, the second connecti...

Embodiment 2

[0083] This embodiment provides an anchoring device, and the anchoring device in this embodiment is a further improvement on the anchoring device in Embodiment 1. refer to Figure 14 and Figure 15 , Figure 14 and Figure 15 They are two structural diagrams of the proximal anchor 100 in the anchoring device in Embodiment 2 of the present invention. In this embodiment, the first protrusion 112 includes at least one second groove 113 .

[0084] Since the first protrusion 112 includes at least one second groove 113 . Therefore, the roughness of the contact surface 110 can be further increased, thereby further increasing the frictional resistance of the proximal anchor 100 relative to tissue movement, thereby further improving the wall-attachment performance of the proximal anchor 100 and reducing the relative resistance of the proximal anchor 100. The risk of tissue displacement further improves the anchoring stability of the anchoring device; the contact area between the co...

Embodiment 3

[0093] This embodiment provides an anchoring device. The difference between the anchoring device in this embodiment and the anchoring device in Embodiment 1 is that, refer to Figure 16 , Figure 16 It is a structural schematic diagram of the proximal anchor 100 in the anchoring device in the third embodiment of the present invention. In this embodiment, the concave portion includes a plurality of third grooves 115 provided on the contact surface 110 .

[0094] Such as Figure 16 As shown, a plurality of third grooves 115 are distributed in a dot shape. The shape of the third groove 115 on a section perpendicular to the contact surface 110 may be V-shaped, U-shaped or rectangular. The third groove 115 has a circular shape on a cross section parallel to the contact surface 110 . In other embodiments, the shape of the third groove 115 on a cross section parallel to the contact surface 110 may be an ellipse. Preferably, the plurality of third grooves 115 are evenly distribut...

Abstract

The invention provides an anchoring piece and an anchoring means; and the purpose of the invention is to solve the problem of liable displacement of existing anchoring pieces and anchoring means afterimplantation. The anchoring piece comprises a contact surface and a non-contact surface. The contact surface is used for realizing mutual contact with a tissue, and composes at least one concave partand / or one convex part. The anchoring means comprises a distal anchor, a connecting piece, and the anchoring piece; the connecting piece is selectively connected with the anchoring piece; and the connecting piece is fixedly connected with the distal anchor. According to the anchoring piece and the anchoring means disclosed by the invention, for the anchoring piece comprises the contact surface and the non-contact surface while the contact surface comprises at least one concave part and / or one convex part, roughness of the contact surface can be higher than roughness of the non-contact surface; and thus, wall adhesion performance of the anchoring piece can be improved so as to reduce risk of displacement of the anchoring piece relative to the tissue. Therefore, anchoring stability of the anchoring apparatus is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anchoring piece and an anchoring device. Background technique [0002] Benign prostatic hyperplasia is the most common benign disease causing voiding disorders in middle-aged and elderly men. The main manifestations are histological hyperplasia of prostatic stroma and glandular components, anatomical prostatic enlargement, clinical symptoms dominated by lower urinary tract symptoms, and urodynamic bladder outlet obstruction. [0003] In addition to drug therapy, the surgical methods for benign prostatic hyperplasia include the following: (1) transurethral resection of the prostate; (2) suprapubic or retropubic prostatectomy; (3) laser enucleation or resection of the prostate; (4) Minimally invasive treatment including prostate stent. [0004] Minimally invasive treatments, including prostate stents, typically employ an anchor, which is a permanent implant used to...
