Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically, to an actuator and a medical device. Background Art
[0002] In the medical field, artificial contractile structures are widely used in the treatment of diseases such as urinary incontinence due to their adjustability and adaptability. As a key component for controlling artificial contractile structures, an actuator controls the contraction and expansion process of artificial contractile structures.
[0003] In the prior art, the receiving sensor of the actuator is usually directly disposed on the control circuit. When the sensor fails, it is usually necessary to replace the entire actuator, which not only increases the treatment cost but also brings unnecessary pain and risks to patients. Summary of the Utility Model
[0004] The problem solved by the utility model is that it is difficult to replace the sensor when it fails because the sensor is integrated into the control circuit.
[0005] To solve the above problems, the utility model provides an actuator, which includes: a body and a receiving sensor. A fixing part is provided on the outer peripheral surface of the body, and the receiving sensor is detachably disposed on the fixing part; wherein, the receiving sensor is provided with a socket, and the fixing part is provided with an interface adapted to the socket; when the receiving sensor is disposed on the fixing part, the interface is electrically connected to the socket.
[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: A fixing part is provided on the outer peripheral surface of the body, and the receiving sensor is detachably disposed on the fixing part. This design enables the receiving sensor to be replaced individually without replacing the entire actuator. The receiving sensor is provided with a socket, and the fixing part is provided with an interface adapted to the socket. When the receiving sensor is disposed on the fixing part, the receiving sensor is connected to the control circuit of the actuator through the interface to ensure stable signal transmission. The modular setting of the receiving sensor simplifies the operation process of replacing the receiving sensor. Since the receiving sensor is detachably disposed on the fixing part of the actuator, when the sensor fails, it can be replaced individually without replacing the entire actuator, which simplifies the maintenance process of the actuator, reduces the maintenance cost, and at the same time reduces the surgical risks and patient pain that may be brought about by replacing the entire actuator.
[0007] Furthermore, the receiving sensor includes: a main body and a sensor module. The main body has an inner cavity, and the sensor module is disposed in the inner cavity and fixedly connected to the main body.
[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Through the modular design of the receiving sensor, the convenience of its maintenance and replacement is improved. Since the sensor module is designed as a detachable part, when the sensor fails, only the receiving sensor needs to be replaced, rather than replacing the entire receiving sensor. The modular design enhances the reliability and stability of the receiving sensor. By arranging the sensor module in the inner cavity of the main body and fixedly connecting it to the main body, this structure effectively protects the sensor module from the external environment and reduces the risk of sensor failure caused by changes in the external environment. At the same time, it also makes the replacement of the receiving sensor more convenient and fast.
[0009] Further, the fixing part includes: a first installation groove, and the shape of the first installation groove is adapted to the main body; when the receiving sensor is arranged on the main body, the main body is arranged in the first installation groove.
[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Through the first installation groove of the fixing part, which is adapted to the shape of the main body of the receiving sensor, a firm connection between the receiving sensor and the actuator main body is achieved. Since the first installation groove is adapted to the shape of the main body of the receiving sensor, the installation and disassembly process of the sensor becomes simple and fast. When the sensor needs to be replaced, only the sensor needs to be taken out of the first installation groove and a new sensor can be put in, without a complex operation process. This not only reduces the maintenance difficulty but also reduces the maintenance time and improves the maintenance efficiency. By designing the first installation groove of the fixing part, a firm connection between the receiving sensor and the actuator main body is achieved, reducing the maintenance difficulty and time.
[0011] Further, the fixing part includes a second installation groove, and the main body includes a boss; when the receiving sensor is arranged on the main body, the boss is arranged in the second installation groove, and the outer surface of the boss is smoothly transitioned with the outer peripheral surface of the main body.
[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By adding a second installation groove in the fixing part and matching it with the boss on the main body of the receiving sensor, the stability and reliability of the connection between the receiving sensor and the actuator main body are further enhanced. The tight combination of the boss and the second installation groove prevents the receiving sensor from shaking or shifting during use, thereby ensuring the accuracy and stability of the sensor signal transmission. The outer surface of the boss is smoothly transitioned with the outer peripheral surface of the actuator main body to prevent scratching the patient when the receiving sensor is in the patient's body. When the receiving sensor needs to be replaced, the receiving sensor can be taken out of the fixing part through the boss, simplifying the installation and disassembly process of the receiving sensor and making the disassembly of the receiving sensor more convenient.
[0013] Further, a limiting block is provided in the inner cavity, and a limiting groove is provided in the sensor module. The limiting groove and the limiting block cooperate with each other to limit the relative movement of the sensor module in the inner cavity.
[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By providing a limiting block in the inner cavity and a limiting groove on the sensor module, the position of the sensor module in the inner cavity can be accurately controlled, effectively preventing its relative movement.
[0015] Further, the sensor module is provided with a first groove, and a first sealing ring is provided in the first groove. The first sealing ring is located between the sensor module and the main body.
[0016] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The first sealing ring tightly fills the gap between the sensor module and the main body, effectively preventing impurities such as liquid in the human internal environment from entering the inner cavity, thereby protecting the sensor module from damage. Due to the presence of the first sealing ring, the connection between the sensor module and the main body is tighter, reducing the need for maintenance caused by loosening or falling off.
[0017] Further, the main body is provided with a second groove, and a second sealing ring is provided in the second groove. The second sealing ring is located between the first mounting groove and the main body.
[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The second sealing ring tightly fills the gap between the mounting groove of the fixing part and the main body, effectively preventing impurities such as liquid in the human internal environment from entering the mounting groove and then entering the actuator interior, thereby protecting the internal structures of the receiving sensor and the actuator from contamination and damage. In addition, the second sealing ring can play a fastening role. When the main body is disposed in the first mounting groove, the main body is inserted into the first mounting groove and fixed by the elastic action of the second sealing ring.
[0019] Further, the actuator includes: a motor and a transmission device, and the motor and the transmission device are in transmission connection.
[0020] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The motor and the transmission device provide power for the transmission device. The transmission device is connected to the traction wire of the medical device, providing traction force for the traction action of the traction wire.
[0021] Further, the actuator includes: a power device, and the power device is used to supply power to the motor.
[0022] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The power device, as a dedicated power supply device, can provide continuous and stable power output for the motor, ensuring stable power supply for the actuator.
[0023] The present utility model provides a medical device, which includes an actuator as described in the above technical solution.
[0024] After adopting the technical solution of the present utility model, the following technical effects can be achieved:
[0025] Since the receiving sensor is detachably arranged on the fixing part of the actuator, when the sensor fails, it can be replaced separately without replacing the entire actuator, which simplifies the maintenance process of the actuator, reduces the maintenance cost, and at the same time reduces the surgical risks that may be brought about by replacing the entire actuator.

Detailed Embodiments
[0034] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings.
[0035] Embodiment 1:
[0036] In the prior art, a medical device acts on a human organ. The medical device includes an artificial contraction structure and an actuator. The artificial contraction structure surrounds a hollow human organ such as the urethra, rectum, esophagus or stomach. In order to reduce the diameter of the human organ or occlude the human organ, the artificial contraction structure applies pressure to the organ. Especially in the case of urinary incontinence or fecal incontinence, the artificial contraction structure substantially forms an artificial sphincter, which can be opened and closed by controlling the pressure applied by the contraction band 900. When it is necessary to reduce the diameter of the human organ or occlude the human organ, the patient or doctor sends a closing instruction to the medical device through a remote control. The sensor element provided on the control circuit of the actuator receives the signal and controls the actuator to perform a closing operation. The sensor element of the actuator is usually directly provided on the control circuit. When the sensor fails, it is usually necessary to replace the entire actuator, which not only increases the treatment cost, but also brings unnecessary pain and risks to the patient.
[0037] To solve the above problems, the present embodiment provides an actuator, as Figure 1 shown, the actuator includes: a body 100, a receiving sensor 200 and a control circuit 300.

[0038] Specifically, the receiving sensor 200 includes a signal processing unit and a signal receiving unit. The receiving sensor 200 receives the closing instruction sent by the remote control through the signal processing unit, and sends the closing instruction to the signal receiving unit.

The receiving sensor 200 is modularly arranged, so that the receiving sensor 200 can complete the tasks of receiving instructions and processing the instructions into control signals.
[0039] It should be noted that each receiving sensor 200 and its supporting remote control form a remote control system, and each receiving sensor 200 can only receive the signal sent by its supporting remote control. When the receiving sensor 200 of the actuator needs to be replaced, the receiving sensor 200 and its supporting remote control are replaced.
[0040] Furthermore, as Figure 2 and Figure 4 shown, the receiving sensor 200 includes: a main body 210 and a sensor module 220. The main body 210 has an inner cavity 211, and the sensor module 220 is arranged in the inner cavity 211 and fixedly connected to the main body 210.
[0041] Specifically, the signal processing unit and the signal receiving unit are integrated into the sensor module.
[0042] Furthermore, as Figure 3 shown, the fixing part 110 includes: a first installation groove 111, the shape of the first installation groove 111 being adapted to the main body 210; when the receiving sensor 200 is arranged on the main body 100, the main body 210 is arranged in the first installation groove 111.
[0043] Furthermore, as Figure 3 shown, the fixing part 110 includes a second installation groove 112, and the main body 210 includes a boss 212; when the receiving sensor 200 is arranged on the main body 100, the boss 212 is arranged in the second installation groove 112, and the outer surface of the boss 212 is in smooth transition with the outer peripheral surface of the main body 100.
[0044] Furthermore, a limiting block 213 is arranged in the inner cavity 211, and a limiting groove 222 is arranged in the sensor module 220. The limiting groove 222 and the limiting block 213 cooperate with each other to limit the relative movement of the sensor module 220 in the inner cavity 211.
[0045] Furthermore, as Figure 5 shown, the sensor module 220 is provided with a first groove 223, and a first sealing ring is arranged in the first groove 223. The first sealing ring is located between the sensor module 220 and the main body 210.
[0046] Furthermore, as Figure 4 shown, the main body 210 is provided with a second groove 214, and a second sealing ring is arranged in the second groove 214. The second sealing ring is located between the first installation groove 111 and the main body 210.
[0047] Specifically, when the main body 210 is arranged in the first installation groove 111, the main body 210 is inserted into the first installation groove 111 and is fixed by the elastic action of the second sealing ring.
[0048] Furthermore, the actuator includes: a motor 400 and a transmission device 500, and the motor 400 and the transmission device 500 are in transmission connection.
[0049] Furthermore, the actuator includes: a power device 600, and the power device 600 is used to supply power to the motor 400.
[0050] Specifically, as Figure 1 shown, a control circuit 300, a motor 400, a transmission device 500 and a power device 600 are arranged in the main body 100 of the actuator. The control circuit 300 controls the operation of the motor 400, and the motor 400 transmits power to the artificial contraction structure through the transmission device 500.
[0051] Embodiment Two:
[0052] This embodiment provides a medical device, which includes an actuator as provided in Embodiment 1.
[0053] It should be noted that the medical device acts on a human organ, and the artificial contraction structure surrounds a hollow human organ such as the urethra, rectum, esophagus or stomach. To reduce the diameter of the human organ or occlude the human organ, the artificial contraction structure applies pressure to the organ. Especially in the case of urinary incontinence or fecal incontinence, the artificial contraction structure substantially forms an artificial sphincter, which can be opened and closed by controlling the pressure applied by the contraction band 900.
[0054] Specifically, as Figure 6 shown, the medical device includes an artificial contraction structure and an actuator. The artificial contraction structure includes a contraction band 900, traction wires, and a connector 700. The contraction band is used to surround the human organ. The traction wires are connected to one end of the contraction band 900 to apply a traction force to the contraction band 900, so that the contraction band 900 is tightened. A flexible tube 800 is arranged outside the traction wires. The traction wires and the flexible tube 800 are connected to the transmission device 500 of the actuator through the connector 700. When it is necessary to reduce the diameter of the human organ or occlude the human organ, the patient or doctor sends a closing instruction to the medical device through a remote controller. After the receiving sensor 200 receives the closing instruction, it processes the closing instruction into a control signal and sends it to the control circuit 300. The control circuit 300 controls the motor 400 to work, and transmits the power to the traction wires through the transmission device 500. The traction wires apply a traction force to the contraction band 900, causing the contraction band 900 surrounding the human organ to contract, thereby completing the occlusion of the human organ. Similarly, when it is necessary to open the human organ, the patient or doctor sends an opening instruction again through the remote controller to make the contraction band 900 return to the open state, thereby completing the opening of the human organ.
[0055] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
