Embodiment 1

[0030] This embodiment provides a valve repair jig. With the help of the conveyor 105, the valve repair jig 100 can use the "small transapical incision" technique (cut a small opening about 3 to 5 cm in front of the animal's chest, insert the catheter into the apex of the heart, and insert it along the apex of the heart. up and into the ventricle) to deliver the valve repair jig to the atrium for repair work.

[0031] Such as Figure 1 to Figure 6 As shown, the valve repair clip 100 includes an outer clip 101, an inner clip 102 and a tightening portion 103, the proximal end of the outer clip 101 and the proximal end of the inner clip 102 are arranged in the tightening portion 103, and the outer clip 101 includes a first clip and the second clamping part, the inner clamp 102 includes the third clamping part and the fourth clamping part, between the first clamping part and the third clamping part and between the second clamping part and the fourth clamping part The valve leafle...

Embodiment 2

[0042] The difference between the valve repair jig of this embodiment and Embodiment 1 is:

[0043] In this embodiment, the third clamping part and the fourth clamping part of the inner clip are separated, changed to a hinge, and the control line is added to realize the separate capture of the two valve leaflets, increasing the convenience of capturing the valve leaflets.

[0044] For other specific structures, refer to Embodiment 1.

Embodiment 3

[0046] The difference between the valve repair jig of this embodiment and Embodiment 1 is:

[0047] In this embodiment, serrations are added to the outer side of the outer clip to increase the frictional force of the fit of the valve repair jig after clamping, and to increase the service life of the valve repair jig.

[0048] For other specific structures, refer to Embodiment 1.

Abstract

The invention belongs to the technical field of animal instruments, and particularly relates to a valve repair clamp. The valve repair clamp comprises an outer clamp, an inner clamp and a tightening portion, the near end of the outer clamp and the near end of the inner clamp are arranged in the tightening portion, the tightening portion is connected with a conveyor, the outer clamp comprises a first clamping portion and a second clamping portion, the inner clamp comprises a third clamping portion and a fourth clamping portion, a valve leaflet is clamped between the first clamping portion and the third clamping portion, a valve leaflet is clamped between the second clamping portion and the fourth clamping portion, and the tightening portion is used for fixing the outer clamp and the inner clamp, so that a valve is repaired. According to the valve repair clamp and the application thereof, a specially-made animal valve repair clamp is adopted for an operation, a lesion valve leaflet is clamped, so that the valve is restored to the normal involution level, the structure is simple, the minimally invasive implantation is achieved, the operation is easy, and the problem that an animal heart valve is not completely closed is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of animal instruments, and in particular relates to a valve repair jig and its application. Background technique [0002] "Heart disease" is actually a name for many different types of heart disease. Heart disease is very common in dogs. It is estimated that 60% of older dogs have heart problems. In our canine companions, heart disease is either acquired or congenital, with the vast majority (approximately 95%) being acquired. Acquired heart disease can result from normal aging, injury, or infection and is usually seen in middle-aged and older dogs. Acquired disorders include the muscles themselves or the heart valves. Fewer people are dying of heart disease these days, but unfortunately, the mortality rate of our canine companions is increasing at an alarming rate. Part of this growth can be attributed to advances in veterinary medicine, which have helped dogs live longer. The longer you live, the mor...
