Abstract
The utility model discloses a mitral valve shaping ring, which is composed of a ring body with a handle and a soft material ring, the soft material ring is sleeved on the ring body with the handle with a suitable size. Because the shape and the size of the ring body with the handle are similar to the shape and the size which are formed by the mitral valve of the human heart, so the utility model can ensure the necessary support of the mitral valve in the valvoplasty; and because the medical synthetic glass with a proper rigidity replaces the hard material, so the utility model does not become deformed while using thereby increasing the reliability of the mitral valve shaping ring. Meanwhile, the utility model is equipped with the handle, which is convenient for the operation of the medical staff.
Description
Technical field
This utility model relates to medical instruments field, is meant a kind of apparatus that cardiac operation is used that is used for especially.
Background technology
At present, be widely used in the mitral valvuloplasty ring of cardiac operation, its structure as shown in Figure 1.It is made of soft material ring 1 and hard material 2.Soft material ring 1 is coated on the outside of hard material 2.The soft material ring mainly uses the medical fibre fabric, particularly medical terylene; And hard material is mainly stainless steel silk.
This mitral valvuloplasty ring is used for the valve forming operation, and the history of more than ten years has been arranged.It can make the chronic valvular heart disease patient of part keep the cardiac valve of self, recovers the physiological function of himself, thereby avoids existing not long disadvantage of heart valve replacement surgery postoperative survival phase.
But in use, this mitral valvuloplasty ring also exists some shortcomings, be mainly reflected in: because stainless steel silk has too high elasticity, easy deformation, thus cause whole mitral valvuloplasty ring not to be shaped, complete failure, directly the carrying out of influence operation and patient's rehabilitation.In addition, this structure has also caused the inconvenience of operation.
Summary of the invention
The purpose of this utility model provides a kind of mitral valvuloplasty ring of novelty, can guarantee in the valve forming operation Bicuspid valve to be carried out necessary support and shaping.
For achieving the above object, this utility model is made of ring body with handle and soft material ring two parts.Ring body is positioned at the end of handle, is ellipticity, and its shape is similar to the Bicuspid valve of human heart with size.The shape of soft material ring is also similar to the Bicuspid valve of human heart with size, and it is enclosed within on the ring body suitably.
On the ring body with handle described in the utility model a groove can also be arranged, the soft material ring is enclosed within on the ring body by this groove, can make the soft material ring and have between the ring body of handle closelyr, is unlikely to come off from ring body.
For the blood that makes heart flows more well, the soft material ring also can be the split ring that does not seal, and the length of split ring is 2/3～4/5 of identical shaped and big or small totally-enclosed ring girth.Such structure can guarantee that promptly blood normally flows, and is unlikely to make the soft material ring to come off from the ring body with handle again.
Soft material ring described in the utility model is made by the medical fibre fabric, is generally a kind of in dacron, polypropylene fabric, the politef fabric, all adopts medical grade.
Ring body with handle described in the utility model is made by medical lucite.
The utility model has the advantages that:, can guarantee in the valve forming operation, Bicuspid valve to be carried out necessary support owing to the ring body with handle is similar with size to mitral shape of human heart; And the medical lucite suitable with rigidity replaces hard material, so this utility model can in use not be out of shape, improved the reliability of mitral valvuloplasty ring.Simultaneously, it is furnished with handle, has made things convenient for medical worker's operation.

Fig. 2 is a structural representation of the present utility model
The specific embodiment
As shown in Figure 2, the utlity model has the ring body 4 and the soft material ring 5 two parts formation of handle 3.Have on the ring body 4 of handle 3 groove 6 is arranged.Mitral shape of the shape with the ring body 4 of handle 3 and soft material ring 5 and size and human heart is with big or small similar.Soft material ring 5 is enclosed within the groove 6 of the ring body 4 with handle 3.
Soft material ring among Fig. 2 is made by medical dacron, is a split ring.The length of opening portion is 1/4th of identical shaped and big or small totally-enclosed ring girth.That is, the length of split ring is 3/4ths of identical shaped and big or small totally-enclosed ring girth.
Claims (7)
1, a kind of mitral valvuloplasty ring, it is characterized in that: constitute by ring body with handle and soft material ring two parts, ring body is positioned at the end of handle, and the shape of ring body and soft material ring is similar with size to mitral shape of human heart with size, and the soft material ring set is on ring body.
