Description

Technical Field

[0001] This application generally relates to the field of laser ablation equipment. More specifically, this application relates to an actuator for an implantation device driving system. Background Technology

[0002] Laser ablation equipment includes a laser ablation system and a drive system for controlling it. The drive system includes a control device, a transmission device, and an execution device. The control device manipulates the execution device via the transmission device, allowing the execution device to adjust the direction and position of the implanted instruments (such as fiber optic catheters) of the laser ablation system for more comprehensive and thorough ablation of the patient's lesions. During the procedure, the implantable component of the execution device needs to be inserted into the patient's body to guide the instrument to the lesion. Because there is a gap between the implanted instrument and the implantable component, the patient's bodily fluids may leak through the gap. More seriously, the gap provides a pathway for pathogens to enter the body, increasing the risk of infection. If the gap is completely sealed, the implanted instrument will be fixed in place, making it difficult to adjust its direction and position. Utility Model Content

It should also be understood that the term “and / or” as used in this specification and claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations.

[0024] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0025] This utility model provides an actuator for an implantable device driving system. To better understand this embodiment, the composition of the implantable device driving system will be described first, followed by a detailed explanation of the specific structure of this embodiment. Figure 1 This is a perspective view of the implantation device driving system according to an embodiment of the present invention. Figure 1 As shown, the drive system includes a control device 200, an actuator 100, and a transmission device 300 connecting the control device 200 and the actuator 100. The control device 200 controls the actuator 100 through the transmission device 300, so that the actuator 100 can drive the implanted instrument to perform linear movement and / or rotational movement, thereby adjusting the direction and position of the implanted instrument.

[0026] Figure 2 for Figure 1 The diagram shows an exploded view of the drive system at the actuator. (See diagram below.) Figure 2As shown, the aforementioned actuator 100 includes a frame 110, an insertion component 120, an actuator 130, and a sealing mechanism 140. The insertion component 120 is disposed within the frame 110 and allows the insertion device to pass through it. The actuator 130 is disposed within the frame 110 and connected to the insertion device, and can drive the insertion device to perform linear movement and / or rotational movement relative to the frame 110 under the control of the control device 200. The sealing mechanism 140 is disposed on the insertion component 120 and can be controlled to selectively seal or unseal the gap between the insertion component 120 and the insertion device.

[0027] When using a drive system to control the implanted device for treatment, the actuator 130 can be controlled by the control device 200 to seal the gap between the implanted component 120 and the implanted device, preventing leakage of patient fluids. When the treatment position of the implanted device needs to be changed during the operation, the actuator 130 can be controlled again by the control device 200 to release the seal between the implanted component 120 and the implanted device, ensuring smooth movement of the implanted device within the implanted component 120. Then, the control device 200 drives the implanted device to move linearly relative to the implanted component 120 and / or rotate around its own axis until the implanted device is adjusted to the appropriate treatment position. Finally, the gap between the implanted component 120 and the implanted device is sealed, effectively avoiding uncontrolled leakage of body fluids and the risk of infection, thus improving the safety of the operation.

[0028] In one embodiment, the implantation device is a fiber optic conduit of a laser ablation device. Correspondingly, when the implantation device is a fiber optic conduit, the insertion component 120 can be a cranial screw. In one implementation scenario, during laser ablation surgery, a cranial screw is punctured and inserted into the patient's skull to fix the position of the fiber optic conduit. The cranial screw provides a stable support point for the fiber optic conduit, enabling the fiber optic conduit to be accurately aligned with the predetermined lesion site for ablation treatment.

[0029] like Figure 3 As shown, to increase the installation flexibility of the insert component 120, it is preferable that the insert component 120 is partially inserted into the frame 110. The actuator 100 also includes a locking bolt 160, which can be screwed into the frame 110 and applies pressure to fix the insert component 120. To effectively reduce the possibility of the insert component 120 rotating within the frame 110, the mating surfaces of the insert component 120 and the frame 110 can be set as polygons, such as hexagons, to reduce the possibility of the insert component 120 rotating during the process of fixing the insert component 120 with the locking bolt 160, thus ensuring the positioning stability of the insert component 120.

[0030] like Figure 2 and Figure 3 As shown, the insertion component 120 further includes a channel 121 for receiving an implanted device. The channel 121 includes a constant section 1211 and an enlarged section 1212 closer to the frame 110 than the constant section 1211. The sealing mechanism 140 includes an elastic ring 141 and a pressure member 142. The elastic ring 141 is disposed between the insertion component 120 and the implanted device, and is located within the enlarged section 1212 of the insertion component 120. A portion of the pressure member 142 is disposed within the enlarged section 1212 of the insertion component 120, and reciprocates within the enlarged section 1212 of the insertion component 120 when manipulated to apply or release pressure to the elastic ring 141.

[0031] As an example, when sealing is required, the control device 200 can drive the pressure member 142 to move within the channel 121 towards the elastic ring 141, so that the pressure member 142 can apply pressure to the elastic ring 141 within the channel 121 and force the compressed elastic ring 141 to seal the gap between the implanted component 120 and the implanted device. When unsealing is required, the control device 200 can drive the pressure member 142 to move within the channel 121 away from the elastic ring 141, so that the pressure member 142 can release pressure on the elastic ring 141 within the channel 121 and force the elastic ring 141 to return to its original shape, thus unsealing the gap between the implanted component 120 and the implanted device.

[0032] To achieve a better seal between the implantable component 120 and the inserted device, the material of the elastic ring 141 needs to be selected to have a certain degree of elasticity and flexibility, and to adapt to the channel 121 of the implantable component 120. As an example, the elastic ring 141 can be a ring structure made of rubber or silicone. Both rubber and silicone have good sealing properties, preventing leakage of patient fluids. Furthermore, their elasticity and flexibility allow them to fit into the channel 121 of the implantable component 120, enabling the switching between sealing and desealing.

[0033] In one embodiment, the pressing member 142 is a hollow bolt, which is sleeved outside the insertion device and threadedly connected to the expanded diameter section 1212 of the insertion component 120 as it enters the insertion component 120. More specifically, the expanded diameter section 1212 includes a first sub-expanded diameter section 1212a and a second sub-expanded diameter section 1212b. The second sub-expanded diameter section 1212b is closer to the frame 110 than the first sub-expanded diameter section 1212a, and the radial dimension of the first sub-expanded diameter section 1212a is smaller than the radial dimension of the second sub-expanded diameter section 1212b. The first sub-expanded diameter section 1212a is used to accommodate and lock the elastic ring 141, and the second sub-expanded diameter section 1212b has an internal thread structure that mates with the hollow bolt.

[0034] As an example, when sealing is required, the control device 200 can drive the hollow bolt to rotate forward within the second sub-expansion section 1212b. While rotating forward, the hollow bolt can move forward along the axial direction of the implant component 120, thereby pushing the elastic ring 141 towards the gap between the implant component 120 and the implanted device. This applies pressure to the elastic ring 141, causing it to deform within the first sub-expansion section 1212a, thus sealing the gap between the implant component 120 and the implanted device. When unsealing is required, the control device 200 can drive the hollow bolt to rotate in the reverse direction within the second sub-expansion section 1212b. While rotating in the reverse direction, the hollow bolt can move in the reverse direction along the axial direction of the implant component 120, thereby releasing the pressure on the elastic ring 141. This allows the elastic ring 141 to recover its deformation within the first sub-expansion section 1212a, thus unsealing the gap between the implant component 120 and the implanted device.

[0035] like Figure 1 and Figure 3 As shown, to improve the smoothness and convenience of the operator driving the hollow bolt to rotate, in some embodiments, the actuator 100 further includes an adapter 150. The adapter 150 is sleeved on the hollow bolt and connected to the transmission device 300, so that the control device 200 can drive the hollow bolt to rotate forward and backward in the insert component 120 through the transmission device 300 and the adapter 150. As an example, the adapter 150 is slidably disposed on the frame 110, and the adapter 150 is fixedly sleeved on the hollow bolt. The control device 200 and the transmission device 300 drive the adapter 150 to rotate, thereby driving the hollow bolt to rotate. It should be noted that there are various specific implementation methods for the connection between the adapter 150 and the hollow bolt, which depends on the design requirements and motion characteristics of the entire transmission device 300 and the control device 200, and no further limitations are made here.

[0036] Next, combine Figure 1 and Figure 2 The aforementioned implementing agency 130 is illustrated by example. Figure 1 and Figure 2As shown, the actuator 130 includes a slider 131, a worm gear 132, a gear 133, and a rack 134. The slider 131 is slidably disposed within the frame 110 and connected to the insertion device. The worm gear 132 is rotatably disposed on the slider 131 and connected to the control device 200 via a transmission device 300. The gear 133 is rotatably disposed on the slider 131 and meshes with the worm gear 132. The rack 134 is fixedly disposed within the frame 110 and meshes with the gear 133. The worm gear 132 can be driven by the control device 200 to rotate in both directions, causing the worm gear 132 to drive the gear 133 to roll on the rack 134, thereby forcing the gear 133 to drive the slider 131, worm gear 132, and insertion device to move linearly. The control device 200 controls the worm gear 132 to rotate through the transmission device 300. The rotation of the worm gear 132 drives the gear 133 to rotate, forcing the gear 133 to move linearly on the rack 134. The movement of the rack 134 drives the slider 131 to move, and the movement of the slider 131 drives the insertion instrument to move linearly.

[0037] It should be noted that the structure of the actuator 130 is not limited to the gear 133 and rack 134 structure described above. It may also include other existing structures that can convert the rotation of the worm 132 into linear motion, such as crank connecting rod, cam, etc. In this embodiment, these will not be listed one by one or described in the accompanying drawings.

[0038] To enable the actuator 130 to drive the insertion device to rotate around its own axis, the actuator 130 also includes a driven bevel gear 135 and a driving bevel gear 136. The driven bevel gear 135 is rotatably mounted on the slider 131 and lockably fitted onto the insertion device. The driving bevel gear 136 meshes with the driven bevel gear 135 and is connected to the control device 200 via the transmission device 300. The control device 200 controls the rotation of the driving bevel gear 136, which in turn drives the driven bevel gear 135 to rotate, thereby causing the insertion device to rotate around its own axis. Besides the aforementioned bevel gear transmission, torque can also be transmitted via chain transmission or gear transmission; however, these will not be listed or described in detail in this embodiment.
