Problems solved by technology

However, because the superimposition of the two ends of the polyester cloth tube is thicker than other parts of the polyester cloth tube, and the sutures will also form multiple protrusions when suturing the superimposition, so the surface of the polyester cloth on the artificial annuloplasty ring is due to The protrusions formed by suturing both ends of the polyester cloth tube are thicker than other parts of the polyester cloth, and there are more protrusions. The thicker and more protrusions of the polyester cloth will not only hinder the flow of blood flow, but also reduce the blood flow. The flow rate also increases the probability of thrombus formation on the surface of polyester cloth

Embodiment Construction

[0052] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0053] Such as figure 1 and figure 2 As shown, an artificial annuloplasty ring 10 includes an inner tube 11 , a flexible material layer 12 wrapped around the inner tube 11 , and a fabric layer 13 wrapped outside the flexible material layer 12 . The artificial annuloplasty ring 10 is a flexible non-planar ring body, the inner tube 11 is made of metal or polymer material, the flexible material layer 12 is preferably silica gel, and the fabric layer 13 is preferably polyester cloth. In addition, the prosthetic annuloplasty ring 10 is also provided with marking lines 14 along the circumference of the forming ring 10 and left triangular marking points 15 , right triangular marking points 16 and rear marking points 17 arrange...

Abstract

The invention discloses an artificial valve forming ring, which comprises an inner tube, a flexible material layer wrapped outside the inner tube, and a fabric layer wrapped outside the flexible material layer. The fabric layer is a closed-loop structure, which has two ends sewn by sutures, both ends have a plurality of annular structures arranged at intervals, and the sutures alternately pass through the annular structures at both ends to suture the two ends . The fabric layer of the artificial valvuloplasty ring of the present invention not only has little influence on the flow velocity of the blood flow, but also reduces the probability of thrombus formation.

Description

technical field [0001] The invention relates to a cardiovascular medical device, in particular to an artificial valve forming ring and a sewing method thereof. Background technique [0002] The existing artificial annuloplasty ring generally has a three-layer structure, the innermost layer is a metal or polymer material support, the middle layer is a silica gel layer, and the outermost layer is a polyester cloth tube. In the process of preparing an artificial valvuloplasty ring, usually, the silicone layer is sleeved on the outer surface of the support body first, then the polyester cloth tube is sleeved on the silicone layer, and finally the two ends of the polyester cloth tube are laminated on the together, and use the sewing needle connected with sutures along the circumference of the polyester cloth tube to sew the overlapped places of the two ends of the polyester cloth tube together. However, because the superimposition of the two ends of the polyester cloth tube is t...
