The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
As shown in fig. 1 to 3, the present embodiment provides a heart valve retractor comprising: a traction rod 1, a traction part 2 and a traction hook 3.
The two traction rods 1 are oppositely arranged and have the same extension direction, and as shown in fig. 1, the two traction rods 1 have the same shape and extension direction, and the two traction rods 1 can move in directions approaching to or separating from each other.
The traction part 2 extends from the bottom of the traction rod 1, an included angle is formed between the extending direction of the traction part 2 and the extending direction of the traction rod 1, as shown in fig. 2, the orthographic projection shape of the traction part 2 and the traction rod 1 is approximate to an L shape, which is beneficial to the projection of the traction rod 1 in the height direction to be away from the traction part 2, that is, dislocation exists between the traction rod 1 and the traction part 2 in the height direction, so that the situation that the traction rod 1 shields the visual field of the position of the traction part 2 is avoided. As shown by the broken lines in fig. 2 and 3, the traction rod 1 and the traction portion 2 do not fall into the same area in the height direction, so that a dislocation relationship is formed to avoid the traction rod 1 from shielding the traction portion 2.
The two traction parts 2 are positioned at one side of the two traction rods 1 and are suitable for synchronous movement along with the corresponding traction rods 1, and when the two traction rods 1 move in the direction away from each other, the two traction parts 2 also synchronously move in the direction away from each other, so that the traction hooks 3 are convenient for the traction of the valve leaflets. The plurality of traction hooks 3 are arranged at the bottom of the traction part 2, and the plurality of traction hooks 3 can act on the valve leaflet at the same time, so that all positions on the valve leaflet can receive traction force, and the valve leaflet can be easily and smoothly retracted.
For example, in the operation process, an operator can hold the traction rods 1 and contact the traction hooks 3 with the corresponding positions of the valve leaflets, and then drive the two traction rods 1 to move in the directions away from each other, and at the same time, the traction parts 2 and the traction hooks 3 respectively corresponding to the two traction rods 1 move in the directions away from each other, so as to retract the valve leaflets, so that the operation process is quite convenient. Moreover, because the traction part 2 and the traction rod 1 are staggered in the height direction, the traction rod 1 can not block the visual field of an operator, so that the operator can clearly see the boundary and the subvalvular structure.
The heart valve retractor provided by the embodiment can be easily pulled by using the traction rod 1, and the traction rod 1 and the traction part 2 have a dislocation relation, so that the traction rod 1 can not shade the visual fields of the traction part 2 and the traction hook 3, and an operator can clearly see the juncture and the subvalvular structure.
As shown in fig. 1, in this embodiment, the heart valve retractor further comprises a guiding structure, the guiding structure comprises a guiding rod 4, through holes are formed in the two traction rods 1, and the guiding rod 4 sequentially passes through the two through holes. For example, through holes can be formed in the two traction rods 1 respectively, the shapes and the axes of the two through holes are the same, so that the two traction rods 1 can move towards directions close to or away from each other under the action of the wires of the guide rods 4 through the through holes, the bottoms of the two traction rods 1 can move smoothly, and the operation difficulty of traction is reduced.
As shown in fig. 1, in this embodiment, the two ends of the guide rod 4 are movably provided with a first limiting member 51 and a second limiting member 52, the first limiting member 51 and the second limiting member 52 can move in a direction approaching or separating from the traction rods respectively, the distance between the first limiting member 51 and the second limiting member 52 is the limit distance between the two traction rods 1 and the limit distance between the traction portions 2, and the arrangement of the first limiting member 51 and the second limiting member 52 is beneficial for an operator to control the retraction degree of the valve leaflet before or during an operation. For example, the guide rod 4 may be provided with external threads, and the first and second limiting members 51 and 52 may be provided with internal thread circular holes, so that the distance between the first and second limiting members 51 and 52 is controlled by screw-coupling, thereby controlling the retraction degree. Or, the first limiting piece 51 and the second limiting piece 52 can be fixed at two ends of the guide rod 4 through a buckle or other adjustable fastening structure, and the distance between the first limiting piece 51 and the second limiting piece 52 can be adjusted so as to control the distance between the two traction rods 1.
As shown in fig. 1, in this embodiment, the top of the two traction rods 1 is connected with a reset structure 6, the reset structure 6 is suitable for driving the traction rods to move in directions approaching or separating from each other, for example, after applying force to the two traction rods 1, the two traction rods 1 can move in directions approaching or separating from each other, after removing the force, the two traction rods 1 can move to the original positions under the action of the reset structure 6, so that the operation process is simplified.
As shown in fig. 1, in this embodiment, the shape of the reset structure 6 is annular, two movable ends of the reset structure 6 are respectively connected with the tops of the two traction rods 1, the reset structure 6 may be made of an elastic material, for example, may be annular or coil-shaped, the principle of the reset structure 6 is similar to that of a reset spring, when the traction rod 1 moves under the action of external force, the two movable ends of the reset structure 6 obtain elastic potential energy, and after the external force is removed, the two movable ends of the reset structure 6 drive the traction rod 1 to reset through elastic force.
As shown in fig. 1, in this embodiment, the cross section of the traction rod 1 in the length direction is arc-shaped, and the traction portion 2 extends from one side of the traction rod 1 away from the center of the arc-shaped to a direction away from the traction rod 1, so that the traction rod 1 and the traction portion 2 can form a dislocation in the height direction, so as to avoid the traction rod 1 from blocking the view of the position where the traction portion 2 is located.
As shown in fig. 1, in this embodiment, the traction portions 2 are arc-shaped, and the centers of the two traction portions 2 are located between the two traction portions 2, for example, the two traction portions 2 have the same shape and the direction of arrangement, so that the centers of the two traction portions 2 are located between the two traction portions 2, which is beneficial to adapting to the leaflet retraction requirement and avoiding tearing the leaflet She Zaocheng.
As shown in fig. 1, in this embodiment, a plurality of traction hooks 3 are disposed at intervals at the bottom of the traction portion 2, and the plurality of traction hooks 3 disposed at intervals can make a plurality of positions of the valve leaflet all receive traction force, which is beneficial to further improving the retracting effect, so that the subvalve structure is more clearly exposed in the visual field.
As shown in fig. 1, in this embodiment, the traction hook 3 is bent away from the center of the traction portion 2, so that the traction hook 3 can firmly hook the valve leaflet, which is beneficial to the retracting operation.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
