Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a medical stabilization device for stabilizing a delivery system handle during interventional surgery. Background Technology

[0002] Transcatheter cardiac implantation devices deliver the implant to the target tissue location in the heart via a delivery system, and then control the implant's movement through the same system to achieve the surgical objective. However, both the delivery of the implant to the heart and the control of its movement are performed distally via a handpiece. Therefore, the handpiece's posture adjustment and fixation can affect the stability of the surgical procedure. Existing stabilizing stents suffer from problems such as complex structures, insensitive adjustments, and loosening after locking. Patent CN202321390566.0 discloses a stabilizing device for interventional medical devices, including a base, a first support, and a movable support. The first support is mounted on the base. The stabilizing device also includes an adjustment device, which includes an adjustment seat mounted on the base, a threaded rod mounted on the adjustment seat, and a sliding rod. The threaded rod has an external thread. One end of the movable support has a movable block, which has an internal thread that mates with the external thread and a through hole that mates with the sliding rod. The movable block is mounted on the threaded rod and the sliding rod through the internal thread and the through hole. When the threaded rod is rotated, the movable block drives the movable support to move axially along the sliding rod. The drawback of this solution is that the distance between the knob and the movable support is small, resulting in limited rotation space for the operator's hand and inconvenient operation.

[0003] Therefore, those skilled in the art are dedicated to developing a stabilizing device for interventional medical devices, mainly to solve the following technical problems: 1. Insufficient operating space: The distance between the knob and the moving support is small, which restricts the operator's hand rotation; 2. Difficulty in determining the actual adjustment amount: It is difficult to judge the actual forward or backward movement of the delivery system after turning the knob. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a solution using the following technical method: A medical stabilization device includes a base, a first support unit, and a second support unit. The second support unit comprises a fixed frame, an adjustment structure, and a support member. The adjustment structure includes a rotating member, a guide member, a mating member, and a sliding block. The sliding block is fixedly connected to the support member, and the guide member is fixedly connected to the fixed frame. When the rotating member is operated, the mating member moves along the rotating member, and the sliding block moves along the guide member. The rotating member and the guide member are set at an acute angle α.

[0005] As a further improvement of this utility model, the first support unit and the second support unit are respectively fixedly connected to the base.

[0006] As a further improvement of this utility model, the mating part includes a first mating part and a second mating part, the first mating part being threadedly connected to the rotating part, and the second mating part passing through the sliding block.

[0007] As a further improvement of this utility model, the first mating part is provided with an internal thread, and the rotating part includes an external threaded rod and a grip part; and, when the grip part is rotated, the first mating part moves along the external threaded rod.

[0008] As a further improvement of this utility model, during the movement of the first mating part along the external threaded rod, the second mating part drives the sliding block to move, and the center line of the second mating part and the first mating part form an angle b; and the sum of angle a and angle b is 90°.

[0009] As a further improvement of this utility model, the angle α ranges from 5° to 20°.

[0010] As a further improvement of this utility model, angle a is 8° and angle b is 82°.

[0011] As a further improvement of this utility model, the sliding block includes an adapting part and a supporting channel. The adapting part is arc-shaped and has the same shape as the first mating part. The supporting channel is through-type, and the second mating part is tangent to the supporting channel. Furthermore, during the process of the second mating part driving the sliding block to move, the second mating part moves or slides relative to the supporting channel, and the adapting part gradually moves away from the first mating part.

[0012] As a further improvement of this utility model, the sliding block also includes two through holes perpendicular to the support channel. The through holes are connected to the guide member and are used for the sliding block to move along the guide member.

[0013] As a further improvement of this utility model, the adjustment structure includes two guide members, which are respectively arranged on both sides of the rotating member, and the two ends of the guide members are connected to the fixed frame.

[0014] As a further improvement of this utility model, the guide member is an original rod member.

[0015] As a further improvement of this utility model, the external threaded rod is located below the guide member.

[0016] As a further improvement of this utility model, the support member includes an intermediate connecting part and a rear connecting part, and the center lines of the placement points of the first support unit, the intermediate connecting part and the rear connecting part are on a straight line; and the placement points are used to fix or position the conveying system.

[0017] As a further improvement of this utility model, the middle connecting part and the rear connecting part are connected by a connecting rod, the connecting rod being parallel to the guide member; and the distance between the grip part and the connecting rod is greater than the distance between the connecting rod and the guide member.

[0018] As a further improvement of this utility model, the overlapping part of the base and the fixing frame is hollowed out; and the front end and the rear end of the fixing frame are arranged in parallel, and the front end is at an angle b with the base.

[0019] As a further improvement of this utility model, a marking line is provided on the second mating part to indicate the translation distance of the surgeon's delivery system. Beneficial effects

[0020] 1. Compared with the prior art, in this application, the mating part moves along the rotating part, and the sliding block moves along the guide part. The rotating part (external threaded rod) and the guide part form an acute angle α (e.g., 8°). The center lines of the first mating part and the second mating part of the mating part form an angle b = 82°, satisfying the right angle relationship a + b = 90°. This design decomposes the rotational motion of the thread into a precise linear displacement along the guide part, achieving a displacement amplification effect. For example, when the thread lead is L, the actual moving distance of the sliding block is L × cos(α). At the same time, when the second mating part (guide rod) drives the sliding block to move, its tangential design with the support channel reduces frictional resistance.

[0021] 2. Compared with the prior art, the distance between the grip and the connecting rod in this application is greater than the distance between the connecting rod and the guide, forming a stepped spatial distribution. For example, the grip extends 2 to 5 cm below the guide, avoiding collision between the surgeon's hand and the support, and increasing the rotation radius by more than 50%. At the same time, the external threaded rod is located below the guide, reducing the height of the operating plane and adapting to the natural hand position of the surgeon in a sitting or standing position.

[0022] 3. Compared with the prior art, the two parallel guides of this application are symmetrically distributed on both sides of the threaded rod, forming a triangular stable frame, which can counteract the offset caused by unilateral force.

[0023] 4. Compared with the prior art, the hollow base of this application is lightweight. While maintaining the rigidity of the base, the hollow gaps allow the patient's position to be observed through the device during the operation, avoiding the obstruction of the field of vision by the traditional solid base.

[0024] The embodiments of this application can achieve other advantageous technical effects not listed one by one, which may be partially described below; and these other technical effects can be expected and understood by those skilled in the art after reading this application.
