Embodiment 1
[0030] Such as Figure 1-9 As shown, the braided mesh valve repair clamp of this embodiment is used for valve repair treatment, which can be performed by "transseptal technique" (that is, inserting the catheter into the right femoral vein, up the inferior vena cava and into the Right atrium. Then the septum is punctured and the catheter is threaded into the left atrium) The repair jig is sent to the left atrium for repair work.
[0031] Specifically, the main body 100 of the braided mesh valve repair clip includes a braided mesh clip 103, a valve clip 104, a top seat 101, a base 102, and an auxiliary clamping bracket.
[0032] The braided net clip 103 is a braided mesh structure and has elasticity, including a column-shaped abutting column at the top and two clamping strips extending symmetrically against the bottom of the column; a filler 106 is wrapped inside the abutting column, and the top of the abutting column and the The top seat 101 is connected; the front part of the...
Embodiment 2
[0040] The braided mesh valve repair clip of this embodiment differs from Embodiment 1 in that:
[0041] In this example, the auxiliary clipping bracket is omitted, and the braided mesh clip material uses materials with sufficient elasticity and yield strength to simplify the structure and reduce the overall weight.
[0042] For other structures, refer to Embodiment 1.
Embodiment 3
[0044] The braided mesh valve repair clip of this embodiment differs from Embodiment 1 in that:
[0045] In this example, the end of the guide wire of the control wire adopts a circular ring shape. After the valve clip captures and clamps the valve, the local control wire is retained, and can be reused in the later stage for the recovery of the delivery device or the replacement of the repair fixture.
[0046] For other structures, refer to Embodiment 1.

Abstract
The invention relates to the technical field of medical instruments, in particular to a woven-mesh-shaped valve repair clamp which comprises a woven mesh clamp, a valve clamp, a top seat and a base, wherein woven mesh clamp is of a woven mesh structure, has elasticity and comprises an abutting column with a columnar top and two clamping strips extending symmetrically from the bottom of the abutting column; filler is wrapped in the abutting column, and the top of the abutting column is connected with the top seat; the front sections of the clamping strips are bent upwards from the extending position of the abutting column to form a clamping surface of the woven mesh clamp with the abutting column, and the rear sections of the clamping strips are bent reversely and extend to be connected tothe base; and the valve clamp is fixed in the clamping surface of the woven mesh clamp. According to the woven mesh valve repair clamp, the overall weight of the clamp is reduced through integrated weaving of the woven mesh clamp, so that the clamp is not prone to being damaged and losing functionality, the preparation process is simple, more excellent tensile and anti-fatigue capacity is achieved, the functional life of a valve is prolonged, the clamp is beneficial to long-term health of a patient, and the success rate of an operation and the convenience of the operation are improved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a braided mesh valve repair clip. Background technique [0002] Regurgitation is a common valvular disorder. Regurgitation is due to the inability of the valve leaflets to close completely, causing blood to flow back into the pumping chamber. Valve ring expansion, valve leaflet prolapse, and valve leaflet movement obstruction are the main causes of regurgitation. Many diseases, such as rheumatic heart disease , Endocarditis causes valvular lesions that impair valvular function. [0003] At present, there are mainly valve replacement techniques and valve repair techniques for valve leaflet treatment. Leaflet replacement technology uses artificial valves to replace existing diseased or abnormal heart valves. This kind of replacement operation often requires open chest operation, which causes great damage to the patient's body. Valve repair therapy, which uses a delivery...
