Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention.
Generally, in a replacement implantation operation of a biological valve, the size of an opening is often in a technical opposite relation to the operation view, and a larger opening is required to obtain a larger operation view, so that a patient is wounded more, and the operation view is affected by reducing the size of the opening, so that the operation difficulty is increased. Therefore, a great deal of innovation and improvement has been made on the problem for a long time, but the problem is not solved well.
The invention aims at the problems, and improves the valve holder, and the valve holder can well solve the problems of small operation field and high operation difficulty when being used for small incision valve replacement operation.
In general, the valve holder is used as a carrier for a biological valve implantation operation for fixedly disposing a biological valve, as shown in fig. 1, the valve holder 10 is disposed in a disk-like structure in the present embodiment, and entirely constitutes one lens having positive optical power. In general, positive optical power, which may also be referred to as positive refractive power, means that the lens has a positive focal length. That is, the valve holder 10 is a convex lens in a sheet shape, which has a remarkable advantage in that the view of the object side can be enlarged by means of the valve holder when the biological valve is delivered to the implantation site of the heart by the valve holder, thereby enlarging the operation visual field of the operator, and the imaging of the valve leaflet and the like in the visual field can be enlarged, so that the operator can more clearly observe the operation position under the conditions of narrow incision and long distance, which is very important in the biological valve replacement operation.
In one embodiment, the valve holder 10 is in the shape of a disk that mates with a biological valve, based on the shape conventionally provided by biological valves. Thus, the size of the valve holder is reduced to the greatest extent and the requirement on the size of the operation opening is reduced while the biological valve is effectively fixed based on the structure of the valve holder.
In one embodiment, the end surface of the valve holder 10 that mates with the biological valve is provided with a positioning structure 105 for positioning the position of the biological valve, as shown in fig. 3. Referring to the arrangement of the biological valve shown in fig. 7, the biological valve is cooperatively arranged between one end far from the valve angle and the end of the valve holder, the positioning structure arranged on the end face of the end of the valve holder can be a convex or concave structure capable of being matched with the end of the biological valve, and when the two structures are matched, the biological valve is cooperatively embedded into the convex or concave structure, so that the displacement of the biological valve in the horizontal plane of the end face is limited. Thus, the biological valve can be positioned and simultaneously the auxiliary is provided for the fixed connection of the biological valve on the valve holder.
In one embodiment, the valve holder 10 is provided with an operating hole 101 for facilitating removal of the valve holder of this construction. Existing valve holders are usually configured as a bracket structure with a plurality of clamping arms based on the aspects of size, operation or connection with biological valves, and the disc type structure in the implementation is rarely adopted; in order to facilitate the removal of the valve holder in this embodiment, an operation hole for facilitating the insertion of the forceps is provided in the valve holder, and the valve holder is removed through the operation hole.
On the other hand, as for the valve holder in the above embodiment, as a biological valve replacement assembly usable for a biological valve replacement operation, as shown in fig. 2, a handle holder 20 is included, the handle holder 20 being for connecting an operation handle 30 with the valve holder 10 so that an operator can send a biological valve on the valve holder to an implantation site through the operation handle, and the handle holder in the replacement assembly should be easily separable from the valve holder based on the function to be performed by the valve holder. Thus, in the surgical operation, after the biological valve is sent to the implantation position, the handle seat is separated from the valve holder, and then the handle seat is taken out, at this time, the whole valve holder is exposed to the visual field of an operator, so that the valve holder can play a role in enlarging the operation visual field.
The connection between the handle base 20 and the valve holder 10 is here conceivable by connecting the handle base to the valve holder with a binding-wire, here called handle binding-wire 201; the separation between the handle seat and the valve holder can be realized only by cutting off the handle binding wire in the operation process. As a further improvement, the valve holder 10 is fixedly connected with the handle seat 20 by a handle binding wire 201, specifically, the handle seat is fixedly connected with the valve holder by a handle binding wire 301 sequentially passing through a first connecting hole 202 arranged on the handle seat and an operating hole 101 arranged on the valve holder 10 along the wire running direction. The valve holder is connected with the handle seat by the binding wire, so that the handle seat and the valve holder can be separated by one-time cutting operation, and the connecting mode can facilitate operation in operation and reduce the difficulty of operation.
Referring to fig. 1, an assembly hole 102 is provided at a central position of the valve holder 10, into which the lower end of the handle base is fitted and positioned; two operation holes 101 are respectively arranged on the two sides of the assembly hole on the valve holder 10; four first connecting holes 202 are arranged on the handle base 20, two first connecting holes 202 are in a group, and two groups of first connecting holes 202 are respectively arranged corresponding to the two operation holes 101. Referring to fig. 3 and 4, the handle binding wire is inserted into one of the first connecting holes of one of the groups, inserted into the other of the operating holes after passing through the corresponding one of the operating holes, inserted into one of the first connecting holes at the corresponding position, inserted into the other of the first connecting holes of the group after passing out of the first connecting hole, inserted into the other of the operating holes after passing through the corresponding one of the operating holes, and inserted out of the other of the first connecting holes at the corresponding position, and both ends of the handle binding wire are tied and fixed at the position, thereby connecting the handle holder with the valve holder through one of the binding wires.
In this embodiment, the operation hole 101 on the valve holder 10 is used as a connecting structure for connecting the handle base, so that the structure of the valve holder is simpler.
The handle seat 20 is provided with a first binding-wire cutting structure 203, the first binding-wire cutting structure 203 may be two brackets arranged on the handle seat, the two brackets are arranged at intervals, the handle binding-wire 301 is arranged across the first binding-wire cutting structure 203 along the wire direction, and a first cutting groove 231 for suspending the handle binding-wire at the position is formed on the first binding-wire cutting structure 203 so as to conveniently cut the handle binding-wire.
On the other hand, in this embodiment, a biological valve replacement system using the valve holder of the above embodiment is shown in fig. 5, where a biological valve 40 is disposed on the valve holder 10 and fixedly connected to the valve holder 10 by a binding wire. Specifically, an end of the biological valve 40 opposite to the valve angle is abutted against the end face of the valve holder 10 and positioned on the valve holder, and the valve holder 10 is connected with the three valve angles of the biological valve 40 by a valve binding wire 103, so that the biological valve 40 is fixedly connected to the valve holder 10.
The biological valve is connected to the valve holder by adopting the binding wire, and the valve holder can be separated from the biological valve by only cutting one knife during operation, so that the operation is simpler, and the operation difficulty during small incision operation is reduced.
As a connecting structure between the valve holder and the biological valve, referring to fig. 6 and 7, a plurality of sets of fixing structures corresponding to respective valve angles are provided on the valve holder 10 in the present embodiment, each set of fixing structures including two second connecting holes 104; the valve binding wire is wound on one of the second connecting holes and wound on the corresponding valve corner, wound on the adjacent other valve corner and passed through one of the second connecting holes of the other set of fixing structures, then wound on the valve corner at the position, wound on the adjacent other valve corner, sequentially passed through the second connecting holes of the other set of fixing structures and wound on the valve corners in a winding connection mode, and finally knotted and fixedly connected at the positions of the two second connecting holes of the same set of fixing structures at the two ends of the valve binding wire, so that the biological valve 40 is fixedly connected to the valve holder 10.
Referring to fig. 7, in this embodiment, the valve binding wire 103 is connected to each valve corner at one end thereof along the routing direction, so as to form a routing structure for closing one end of the valve corner on the biological valve. The adoption of the wiring mode that the valve holder is connected with the valve corners of the biological valve through the valve binding wires increases the wiring path of the valve binding wires to a certain extent, but a structure for sealing the end of the biological valve at the valve corners can be formed between the valve binding wires and the three valve corners, and the advantage is that the structure can effectively prevent the surgical wires for fixing the biological valve from being hung on the valve corners in the operation process, so that the operation is influenced or an operation accident is caused. It is known that, in the biological valve implantation operation, one side of the valve angle is disposed downward, and when the biological valve implantation operation is placed at the implantation position, one side of the valve angle cannot be observed, and at this time, the positional relationship and state between the operation wire and the valve angle are difficult to be observed, and at this time, once the operation wire is hung on the valve angle, the biological valve cannot be fixed to the heart valve, so that the wiring mode and structure adopted in the embodiment can play an important role in practical operation.
Referring to fig. 7, the connection of the valve binding wire 103 on the valve corner may be performed at a position near the valve frame at the end of the valve corner, so that the valve binding wire passes through the coating cloth coated on the valve frame, and thus the valve binding wire is prevented from slipping off the biological valve while being connected with the biological valve, and the function of effectively fixing the valve binding wire is achieved.
Referring to fig. 6, in this wiring manner, the valve binding wire 103 is knotted and fixed between two second connecting holes of the same set of fixing structures, the knotting point 131 of the valve binding wire 103 is located on the upper end surface of the valve holder 10, and at this time, the position of the knotting point of the valve binding wire is not located at the same position as the second binding wire cutting structure 106, so that after the valve binding wire is cut at the position of the second binding wire cutting structure, the valve binding wire is hung on the valve holder and cannot fall off from the valve holder.
Each second connecting hole 104 on the valve holder 10 is provided with a chamfer structure, so that friction between the position of the second connecting hole and the valve holder of the valve binding wire can be reduced, and the valve binding wire can be conveniently separated from the valve holder after the valve binding wire is cut off.
The second binding-wire cutting structure 106 is provided on the valve holder 10, and similarly, the second binding-wire cutting structure 106 may be two brackets provided on the valve holder, the two brackets are provided at intervals, the valve binding-wire 103 is arranged across the corresponding second binding-wire cutting structure along the wire direction, and the second binding-wire cutting structure is formed with a second cutting groove 161 for suspending the valve binding-wire at the position so as to cut the valve binding-wire conveniently.
In an embodiment, a positioning groove 162 may be disposed on the second binding wire cutting structure 106, as shown in fig. 3, the positioning groove 162 may be a groove structure disposed on two brackets on the valve holder, when the valve binding wire spans the two brackets, the valve binding wire 103 is disposed in the positioning groove 162, and the position of the valve binding wire on the brackets is limited by the positioning groove, so that the position of the valve binding wire can be effectively limited, and the valve binding wire can stably connect the biological valve with the valve holder.
In fact, in terms of the structural design of the valve holder, in addition to taking into account the basic functions of the valve holder (for example, for connecting biological valves, handle holders), the simplified design of the valve holder structure has a great influence on the practical function that can be exerted by the valve holder based on the functional characteristics of the valve holder used as a convex lens; therefore, the design of the valve holder, such as the second connecting hole, the operating hole, the assembling hole and the positioning structure, is optimized to minimize the functional influence of the arrangement of the structures on the valve holder used as the convex lens in the invention.
The biological valve replacement system further comprises a handle seat 20, wherein the handle seat 10 and the handle seat 20 are fixedly connected to the valve holder through a handle binding wire 201 sequentially passing through a first connecting hole 202 arranged on the handle seat and an operating hole 101 arranged on the valve holder along the wire direction, and the connecting mode is described in detail in the foregoing and is not repeated here.
The biological valve system can be applied to the replacement of a mitral valve, and can be applied to the implantation replacement of an aortic valve, and referring to fig. 8, the biological valve system comprises a handle seat 20, a valve holder 10 and a biological valve 40, wherein the handle seat is connected with the valve holder through a handle binding wire, and the biological valve is connected with the valve holder through a valve binding wire, so as to facilitate the replacement operation of the aortic valve.
During the implantation operation of the biological valve, the biological valve arranged on the valve holder is sent to the implantation position through the opened incision by the operating handle, then the handle binding wire is cut off at the position of the first binding wire cutting structure on the handle seat, the handle seat is separated from the valve holder, the handle seat is taken out, at the moment, the state of the valve leaf in the heart valve, the position state of the biological valve and the like can be observed by means of the observation and amplification functions of the valve holder, the biological valve and the operation wire are adjusted, then the operation wire is knotted, the biological valve is fixed, and finally the valve holder is taken out, so that the replacement implantation of the biological valve is completed.
