Abstract
The invention relates to an adjustable type tricuspid-valve forming device which comprises a ring body, a right metal wire and a left metal wire. The ring body is formed by connecting of the two rear ends of one bent flexible pipe in a connection mode, the connection position of the ring body is divided into a right end and a left end, two holes are formed in the middle of the ring body, the two holes are connected with a left catheter and a right catheter respectively, one end of the left metal wire is fixed on the inner wall of the left end, the other end of the left metal wire penetrates through the two ends of the connection position of the ring body to be threaded into the right end and threaded out of the right catheter, one end of the right metal wire is fixed on the inner wall of the right end, and the other end of the right metal wire penetrates through the two ends of the connection position of the ring body to be threaded into the left end and threaded out of the left catheter. The left end is sleeved into the right end, or the right end is sleeved into the left end, barb-shaped teeth are arranged on the opposite face of the left end and the right end of the connection position. The adjustable type tricuspid-valve forming device does not need to conduct thoracotomy again, the desired effect can be obtained only by the mode that the device is adjusted to be the inner diameter of the ring body through an adjustment handle, physical and mental pain and economic burdens of a patient can be reduced, and complication and the death rate of a second operation can be avoided.
Description
Technical field
The invention belongs to the cardiac valve technical field of medical instruments, particularly relate to a kind of adjustable Tricusp Valvuloplasty device.
Background technology
Tricuspid incompetence is one of modal heart disease.Tricuspid valvoplasty is the surgical intervention method of MR first-selection, uses the Tricusp Valvuloplasty ring can significantly improve success rate and the durability of MVP in the art.But the MVP postoperative is residual and/or recurrence MR is puzzlement cardiac surgeon's a clinical difficult problem always.Often need to go again valvoplasty or prosthetic valve replacement, this not only increases financial burden, also can cause bigger misery to the patient, and the risk of second operation is apparently higher than operation for the first time.In the past experience shows that the main cause of residual MR is that ring-like number selection of Tricusp Valvuloplasty is improper, and model is bigger than normal and cause the involutory area deficiency of lobe leaf often.
Summary of the invention
Technical problem to be solved by this invention provides a kind of adjustable Tricusp Valvuloplasty device, at the tinsel of the built-in two mutual buckles of traditional forming ring, can unidirectionally relatively move between this two one metal wire, thereby the forming ring internal diameter is diminished.
The technical solution adopted for the present invention to solve the technical problems is: a kind of adjustable Tricusp Valvuloplasty device is provided, comprise ring body, right tinsel and left tinsel, described ring body by a flexible pipe bending after two ends link to each other and to form, described ring body junction is divided into right-hand member and left end, described ring body middle part has 2 holes, connect left conduit and right conduit respectively, described left tinsel one end is fixed on the inwall of left end, the other end passes junction, ring body two ends and penetrates right-hand member and pass from right conduit, described right tinsel one end is fixed on the inwall of right-hand member, the other end passes junction, ring body two ends and penetrates left end and pass from left conduit, described left end is inserted in right-hand member or right-hand member is inserted in left end, have barb-shaped tooth on the opposite face of the junction of described left end and right-hand member, described right tinsel and left tinsel are connected guide wire respectively after passing left conduit and right conduit respectively.
Described left conduit and right conduit and ring body are single piece.
Described left conduit and right conduit and ring body are made by macromolecular material.
Beneficial effect
The invention has the advantages that tinsel is connected with guide wire, pass through the interatrial septum, lead to outside the skin through femoral vein or jugular vein again that the outer end connects regulating handle.After the operation, transesophageal ultrasonography is estimated the effect of MVP, if forming effect is dissatisfied, the forming ring model is excessive.Do not need open chest surgery again, only need to adjust through regulating handle the internal diameter of forming ring, can obtain expected effect.By this method, both can alleviate patient's body and mind misery and financial burden, can avoid complication and the mortality rate of second operation again.
