Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a stabilizer for a heart valve conveying system.
Background
Human heart valves include aortic, pulmonary, mitral and tricuspid valves, which function essentially as unidirectional valves operating in synchronization with the pumping heart. These valves allow blood to flow downstream, but prevent blood from flowing upstream. Diseased heart valves exhibit damage such as narrowing or regurgitation of the valve, thereby impeding the ability of the valve to control blood flow. Such damage can reduce the pumping efficiency of the heart and can be debilitating and life threatening. For example, valve insufficiency may lead to conditions such as cardiac hypertrophy and ventricular dilation. Accordingly, extensive efforts have been made to develop repair or replacement of damaged heart valves.
The prosthesis may be used to correct problems associated with a damaged heart valve. For example, mechanical tissue-based heart valve prostheses may be used to replace damaged native heart valves. Recently, significant efforts have been devoted to developing replacement heart valves, particularly tissue-based replacement heart valves, which are less traumatic to the patient than through open heart surgery. Replacement heart valves are designed to be delivered by minimally invasive surgical procedures or even percutaneous surgical procedures. Such replacement heart valves typically include a tissue-based valve body that is attached to an expandable frame and then delivered to the valve annulus of the native heart valve.
The development of prostheses, including but not limited to, replacement heart valves that can be compacted for delivery and then controllably expanded for controlled placement, has proven to be particularly challenging. Another challenge relates to the ability to secure such prostheses relative to intraluminal tissue (e.g., any body lumen or tissue within a lumen) in a manner that prevents trauma.
Delivery of the prosthesis to a desired location in the human body, such as delivery of a replacement heart valve to the tricuspid valve, is also challenging. Obtaining access to perform procedures at the heart or other anatomical locations may require percutaneous delivery of the device through the tortuous vasculature or through open or semi-open surgical procedures. The ability to control the location of the delivery system and the deployment of the prosthesis at the desired location is also challenging.
In summary, the problems of unstable fixation of the handle of the delivery system, unsatisfied adjustment requirements, enlarged surgical wounds, and the like exist, so that corresponding instruments are needed to stabilize the handle of the delivery system.

Detailed Description
The following description of the embodiments of the present application will be made in detail with reference to the accompanying drawings, wherein it is apparent that the embodiments described are only some, but not all embodiments of the present application. All other embodiments, which can be made by a person of ordinary skill in the art without the need for inventive faculty, are within the scope of the application, based on the embodiments described in the present application.
Embodiments of the present utility model provide a stabilizer for a heart valve delivery system that enables reliable stabilization of the heart valve delivery system through a compact structure.
According to one aspect of the present utility model, there is provided a stabilizer for a heart valve delivery system, comprising:
A floor assembly, comprising: the device comprises a bottom plate structure which is horizontally arranged, a bottom plate threaded shaft which is arranged at the proximal end of the bottom plate structure, and a bottom plate sliding block which is sleeved on the bottom plate threaded shaft in a threaded engagement manner;
An angle plate assembly, comprising: an angle plate pivotally connected at a distal end to the base plate structure;
a fixation system for fixing the heart valve delivery system, which is arranged on the angle plate;
an angle support having a lower end pivotally connected to the floor slider and an upper end pivotally connected to a lower surface of the angle plate;
The rotation of the bottom plate threaded shaft enables the bottom plate sliding block to linearly move, the lower end of the angle support body which is pivotally connected with the bottom plate sliding block is driven to linearly move, the angle of the angle support body relative to the horizontal plane is changed, and the angle of the angle plate which is pivotally connected with the upper end of the angle support body relative to the horizontal plane is changed.
Thus, by means of the stabilizer for a heart valve delivery system (simply referred to as stabilizer), the heart valve delivery system (e.g., a handle portion thereof) is supported and fixed by the fixing system provided on the angle plate, and the inclination angle adjustment of the angle plate is achieved by the cooperation of the base plate assembly and the angle support, whereby the heart valve delivery system fixed on the angle plate can be brought to a proper angle and kept in a stable posture as needed.
When it is desired to adjust the angle of inclination of the angle plate, the base plate threaded shaft may be rotated such that the base plate slider in threaded engagement therewith moves linearly (e.g., toward or away from the distal end of the base plate structure), thereby causing the lower end of the angle support pivotally connected to the base plate slider to correspondingly move linearly, and the upper end of the angle support (which may be, for example, an angle support plate or a rod) as a rigid structure moves correspondingly to generate a change in height (raise or lower), the angle plate and the base plate structure are pivotally connected at the distal end and pivotally connected at the lower surface thereof to the upper end of the angle support, whereby the change in height of the upper end of the angle support causes a change in the angle of inclination of the angle plate (e.g., when the base plate slider pivotally connected to the lower end of the angle support body moves toward the distal end, the upper end of the angle support supports the angle plate upward at the pivotal connection), thereby effecting adjustment of the angle of inclination of the angle plate, whereby the heart valve delivery system (e.g., a handle portion thereof) secured to the angle plate can be finely adjusted to a desired posture and held, and the wound is avoided from the risk of the surgical procedure being enlarged or even being unaffected by the posture of the heart valve delivery system.
It follows that by the stabilizer for a heart valve delivery system provided by the embodiments of the present utility model, reliable stabilization of the heart valve delivery system can be achieved by a compact structure.

Optionally, in any embodiment, the locking mechanism includes a fixing member and a rotating member, and the base plate knob is connected to the base plate threaded shaft through the rotating member, wherein in the locked state, the rotating member is fixed to the fixing member in a snap fit manner so as not to rotate, so that the base plate knob connected to the rotating member cannot rotate to prohibit rotation of the base plate threaded shaft, and in the unlocked state, the rotating member is released from the fixing member so as to be rotatable, so that the base plate knob connected to the rotating member can rotate to permit rotation of the base plate threaded shaft.
Optionally, in any embodiment, the locking mechanism further includes a movable locking lever, when the locking lever moves to the first position and is in the locked state, the rotating member is engaged with the fixing member and is fixed so as not to rotate, so that the floor knob connected to the rotating member cannot rotate to prohibit rotation of the floor screw shaft, and when the locking lever moves to the second position and is in the unlocked state, the rotating member is disengaged from the fixing member and can rotate, so that the floor knob connected to the rotating member can rotate to allow rotation of the floor screw shaft.

Optionally, in either embodiment, the distal positioning pin passes through a positioning hole in the upper end of the distal holder and extends in an obliquely downward direction toward the main body of the heart valve delivery system.
