Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to a driver for medical equipment. Background Art
[0002] In order to treat diseases such as urinary incontinence, fecal incontinence, gastroesophageal reflux disease, etc., a medical device is usually implanted in the patient's body. The medical device includes a contractile structure and a driver for driving the contractile structure to tighten or loosen the organ. For example, the medical device is implanted in the body of a patient with urinary incontinence, and the driver drives the tightening structure to tighten or loosen the urethra to treat the urinary incontinence.
[0003] Specifically, a power supply component is provided in the medical device to supply power to the power supply component, and the method of fixing the power supply component in the medical device in the related art is relatively simple, for example, the power supply component is installed at the installation position by engaging with the power supply component through a second limiting structure.
[0004] However, there is at least one of the following problems in the related art: the contact area between the second limiting structure and the power supply component is small, so that the local pressure of the contact surface of the second limiting structure on the power supply component is large, which makes the corresponding force-bearing surface of the power supply component easy to deform. Utility Model Content
[0005] The technical problem solved by the utility model is that in the prior art, the contact area between the second limiting structure and the power supply component is small, so that the local pressure of the contact surface of the second limiting structure on the power supply component is large, which in turn causes the corresponding force-bearing surface of the power supply component to be easily deformed.
[0006] To solve the above problems, on the one hand, the utility model provides a driver for a medical device, wherein the medical device is provided with a contraction structure, which can tighten or loosen an organ, and the driver comprises a shell, which is provided with a accommodating cavity; a driving component, which is arranged inside the shell, connected to the contraction structure, and drives the contraction structure to contract or expand; a power supply component, which is arranged at an installation position of the accommodating cavity, and connected to the driving component; and a first limiting structure, which is arranged around the circumferential position of the installation position to limit the power supply component to the installation position.
[0007] Compared with the prior art, the technical effects achieved by adopting this technical solution are: on the one hand, the contact area between the first limiting structure and the power supply component is increased, and the local pressure of the first limiting structure on the power supply component is reduced, thereby avoiding the situation in which the corresponding force-bearing surface of the power supply component is easily deformed when the power supply component collides with the second limiting structure during the patient's movement, causing the second limiting structure to damage the power supply component. On the other hand, it avoids the situation in which the power supply component is prone to shaking in the accommodating cavity of the driver during the patient's movement, thereby avoiding the situation in which the power supply component collides with other components in the driver, thereby reducing damage to the power supply component.
[0008] In one example of the utility model, the first limiting structure includes a first limiting member, which is disposed around one end of the power supply component; and a second limiting member, which is disposed around the other end of the power supply component; wherein the first limiting member cooperates with the second limiting member to limit the movement of the power supply component.
[0009] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the cooperation between the first limit member and the second limit member ensures that the power supply component has a fixed spatial position inside the medical device, so that even when the patient moves, the power supply component is not prone to collision with other internal components, thereby further reducing damage to the power supply component.
[0010] In one example of the utility model, the first limiting structure includes a plurality of first limiting protrusions, the plurality of first limiting protrusions are arranged around one end of the power supply component, and the power supply component at least partially abuts against the plurality of first limiting protrusions; a plurality of second limiting protrusions, the plurality of second limiting protrusions are arranged around the other end of the power supply component, and the power supply component at least partially abuts against the plurality of second limiting protrusions; wherein the protruding portions of the plurality of first limiting protrusions and the protruding portions of the plurality of second limiting protrusions are both arc-shaped protrusions, and the first limiting protrusions cooperate with the second limiting protrusions.
[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is: further reducing the damage to the power supply component. Specifically, compared with the sharp structure, the arc-shaped protrusion structure increases the contact area between the first limiting protrusion and the second limiting protrusion and the power supply component, thereby reducing the local pressure on the power supply component and avoiding damage to the power supply component due to concentrated pressure.
[0012] In an example of the present invention, the driver further comprises a buckling member, which is arranged at a position of the first limiting structure corresponding to the installation position, so as to limit the power supply component to the installation position.
[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the stability of the power supply component installed in the accommodating cavity is improved.
[0014] In one example of the utility model, the driver also includes a third limiting protrusion, which is arranged on a side of the snap-fitting piece close to the power supply component, and the length of the third limiting protrusion is greater than the distance between the snap-fitting piece and the power supply component, so that when the power supply component is installed in the accommodating cavity, the third limiting protrusion and the power supply component abut against each other.
[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting a third limiting protrusion, the power supply component is prevented from moving in position, resulting in poor contact between the power supply component and the control unit, thereby further improving the stability of the power supply component.
[0016] In an example of the present invention, the buckle component is connected to the first limiting structure in a detachable manner.
[0017] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the power supply component can be detachably installed on the first limiting structure through the buckle, so that when replacing the power supply component, it is convenient for the user to disassemble and assemble the power supply component, thereby improving the convenience of the driver.
[0018] In an example of the present invention, either one of the buckling member and the first limiting structure is provided with a buckling protrusion, and the other is provided with a locking hole matched with the buckling protrusion.
[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is: the convenience of the drive is further improved.
[0020] In an example of the present invention, the driver further comprises a paddle, which is arranged on the buckle, so that the buckle can be controlled to move closer to or farther from the first limiting structure by holding the paddle.
[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is that during the process of disassembling and assembling the power supply components, the user can operate more conveniently, thereby further improving the convenience of the driver.
[0022] In an example of the present invention, the driver further includes a control unit, which is disposed inside the housing and controls the driving component.
[0023] On the other hand, the utility model further provides a medical device, which includes a driver for the medical device as in any of the above technical solutions.
[0024] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: Since this technical solution includes the driver as described in any of the above technical solutions, this technical solution has the beneficial effects as described in the above technical solutions, which will not be repeated here.
[0025] After adopting the technical solution of the utility model, the following technical effects can be achieved:
[0026] (1) The driver of the utility model is arranged in the installation position by the first limiting structure, thereby increasing the contact area between the second limiting structure and the power supply component, reducing the local pressure of the second limiting structure on the power supply component, and avoiding the second limiting structure causing damage to the power supply component when the power supply component collides with the second limiting structure during the patient's movement;
[0027] (2) The driver of the utility model prevents the power supply component from shaking during the patient's exercise, causing the power supply component to collide with other components inside the medical device, thereby reducing damage to the power supply component;
[0028] (3) The driver of the utility model is provided with a third limiting protrusion to prevent the power supply component from moving, which may cause poor contact between the power supply component and the control unit, thereby further improving the stability of the power supply component;
