Description

Technical Field

[0001] This utility model belongs to the field of medical device ablation technology, and particularly refers to ablation components and medical devices for automated operation. Background Technology

[0002] Existing technologies have employed various energy delivery methods in medical treatment, including radio frequency, microwave, high intensity focused ultrasound (HIFU), and pulsed electric field (PEF).

[0003] Existing systems mostly employ methods such as single-handed operation of the rotating wheel, single-handed pushing of the slider, or two-handed advancement or retraction. The commonly used manual control of consumables for forward and backward movement, opening and retrieval, is not quick or efficient enough for use with endoscopes, various channels, or other new devices (such as robots). When using endoscopes and channels, precise positioning or accurate release is impossible. When operating with a robot, consumables need to be repeatedly manipulated at the control panel and robot channel. The high number of repetitive consumable release and retrieval actions per surgery, coupled with the inability to precisely position or release consumables and the repetitive manipulation at the control panel and robot channel, all increase surgical time and complexity. Using two people simultaneously increases personnel costs and may lead to damage to patient cavities due to unretrieval during movement, or other usage errors. Utility Model Content

[0059] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0060] like Figure 1and Figure 7 As shown, this utility model provides an ablation component for automated operation, which mainly includes a consumable handle 100, a first slide groove 102, a first adapter block 101 in the first slide groove 102, the outer dimensions of the first adapter block 101 are matched with the first slide groove 102, and the first adapter block 101 can reciprocate linearly within the first slide groove 102.

[0061] The first catheter 200 has a first channel 201 that extends through it, such as... Figure 6 As shown, one end of the first conduit 200 is fixedly connected to the consumable handle 100; the first connector 300 is fixedly disposed at the other end of the first conduit 200, and the first connector 300 is provided with a first sliding cavity 3001, as shown. Figure 2 and Figure 3 As shown, the first channel 201 connects the first sliding cavity 3001 and the first sliding groove 102;

[0062] The first slider 301 is movably disposed in the first slide cavity 3001. The first slider 301 can reciprocate linearly relative to the first connecting member 300. The first slider 301 is connected to the first adapter block 101, thereby driving the first adapter block 101 to reciprocate linearly along the first slide groove 102.

[0063] The outer sheath tube 400 is mounted on the first adapter block 101. The movement of the first adapter block 101 relative to the consumable handle 100 drives the reciprocating movement of the outer sheath tube 400. An ablation electrode 402 is mounted at the distal end of the outer sheath tube 400. The ablation electrode 402 can be configured with ablation energy. In this embodiment, the ablation electrode 402 can be a columnar electrode with a certain length and its outer diameter matches the size of the outer sheath tube.

[0064] In this embodiment, a consumable handle 100 is provided, and a first adapter block 101 is provided inside the consumable handle 100 to support and fix the outer sheath tube 400, so that the outer sheath tube 400 can move relative to the consumable handle 100. Then, a first catheter 200 and a first connector 300 are provided. The first connector 300 can be connected to an external control device. A first slider 301 is provided inside the first connector 300. The first slider 301 is connected to the first adapter block 101. The first slider 301 is driven by an external drive to move, thereby driving the first adapter block 101 to move. This realizes the automated delivery of the outer sheath tube 400 and the delivery of the ablation electrode 402. The length of the first catheter 200 can be preset as needed to avoid the operator moving back and forth between the instrument interface and the consumable handle 100. Moreover, this device does not require multiple people to operate. While realizing the automation of ablation, its operation process is simple, requires fewer people, and reduces repetitive labor of operators.

[0065] In one embodiment, such as Figure 5 and Figure 6 As shown, a first pull tube 3013 is provided in the first channel 201 of the first conduit 200. The first pull tube 3013 is movably inserted into the first conduit 200, and its two ends are respectively connected to the first adapter block 101 and the first slider 301, thereby realizing the synchronous movement of the first slider 301 driving the first adapter block 101. In this embodiment, the first pull tube 3013 can also be a wire drawing structure.

[0066] In one embodiment, to facilitate the connection between the first pull tube 3013 and the first adapter block 101, one end of the outer sheath tube 400 extends out of the first adapter block 101 with a preset length to allow for connection between the first pull tube 3013 and the first adapter block 101. In this embodiment, the function of the first adapter block 101 is essentially to fix the outer sheath tube 400. Since the outer sheath tube 400 is relatively small, the first adapter block 101 is provided for transition, realizing a sliding connection between the outer sheath tube 400 and the consumable handle 100.

[0067] Furthermore, since the dimensions of the first pull tube 3013 and the outer sheath tube 400 are inconsistent, in order to make the connection structure between the two more stable, a first bridge tube 4001 is provided between the first pull tube 3013 and the outer sheath tube 400. The two ends of the first bridge tube 4001 are respectively sleeved and fixed on the first pull tube 3013 and the outer sheath tube 400. By providing the first bridge tube 4001, the connection area between the first pull tube 3013 and the outer sheath tube 400 is increased, thereby strengthening the connection structure between the two.

[0068] In one embodiment, such as Figure 6 and Figure 7 As shown, in order to achieve external ablation energy penetration to the ablation electrode 402 and avoid pulling on the internal wires, a second channel 202 is provided on the first conduit 200 and the consumable handle 100. The second channel 202 connects the first sliding cavity 3001 and the first sliding groove 102. A conductive needle tube 3031 is provided in the second channel 202, and an electrode needle 1011 is provided in the conductive needle tube 3031, thereby forming a conductive assembly. In this embodiment, the conductive needle tube 3031 is fixedly disposed in the second channel 202, and the electrode needle 1011 is movably inserted into the conductive needle tube 3031, with one end of the electrode needle 1011 fixedly connected to the first adapter block 101.

[0069] Alternatively, the conductive needle tube 3031 can be fixedly mounted on the first adapter block 101, and the electrode needle 1011 can be mounted in the second channel 202, which can also achieve a sliding electrical connection between the two.

[0070] Furthermore, a first wire 303 is provided within the second channel 202, and a second wire 403 is provided within the outer sheath 400. Specifically, one end of the first wire 303 is connected to the conductive needle tube 3031, and the other end of the first wire 303 extends from the first connector 300, forming a first plug 3032, which is connected to an external energy generator. One end of the second wire 403 is connected to the ablation electrode 402, and the other end of the second wire 403 is fixedly connected to the electrode needle 1011. External ablation energy is transmitted through the first wire 303, the conductive needle tube 3031, the electrode needle 1011, and the second wire 403. In this embodiment, by providing the conductive needle tube 3031 and the electrode needle 1011, a sliding electrical connection is achieved, ensuring stable energy transmission and avoiding pulling between wires or the need for very long wires to accommodate the movement of the outer sheath 400. This simplifies the internal connection structure of the consumable handle 100 and prevents mutual interference.

[0071] In one embodiment, the ablation electrode 402 is an expandable basket braid structure, having a first end and a second end. The second end of the ablation electrode 402 is connected and fixed to the outer sheath 400. Figure 1 As shown;

[0072] A second pull tube 401 is provided inside the outer sheath 400. The second pull tube 401 can reciprocate linearly relative to the outer sheath 400. One end of the second pull tube 401 is connected to the first end of the ablation electrode 402, and the other end of the second pull tube 401 extends out of the outer sheath 400 and is connected to the driving structure to realize the reciprocating movement of the second pull tube 401, thereby driving the first end and the second end of the ablation electrode 402 to move closer together, expanding the ablation electrode 402, achieving better adhesion to the wall, and achieving the best treatment effect.

[0073] Specifically, such as Figure 6 and Figure 7As shown, a third pull tube 3023 is provided inside the first pull tube 3013. The third pull tube 3023 can move relative to the first pull tube 3013. The outer diameter of the third pull tube 3023 is adapted to the channel of the first pull tube 3013, so that the movement of the third pull tube 3023 relative to the first pull tube 3013 is without delay. One end of the third pull tube 3023 extends out of the first pull tube 3013. Since the second pull tube 401 and the third pull tube 3023 are not the same size, a second bridge tube 4011 is sleeved on the outside of the second pull tube 401. A certain length of embedding hole is provided at the end of the third pull tube 3023 near the consumable handle 100. The part of the second pull tube 401 with the second bridge tube 4011 is inserted into the embedding hole. The second bridge tube 4011 is used to connect the third pull tube 3023 and the second pull tube 401, so that the third pull tube 3023 drives the second pull tube 401 to move. Furthermore, a second slider 302 is provided on the first slider 301. The second slider 302 is connected to an external driving device, so that the second slider 302 can reciprocate linearly relative to the first slider 301. One end of the third pull tube 3023 passes through the first slider 301 and is connected to the second slider 302. The first slider 301 and the second slider 302 can move synchronously or only the second slider 302 can move, thereby realizing the delivery and expansion of the ablation electrode 402.

[0074] Optionally, the second pull tube 401 and the third pull tube 3023 can be configured as an integral structure, which can also achieve the above purpose, that is, the second slider 302 drives the ablation electrode 402 to contract or expand.

[0075] In this embodiment, the ablation electrode 402 is not limited to a basket braid structure. Optionally, the ablation electrode 402 with an expandable basket braid structure can also be an expandable structure in the form of laser cutting. The purpose is to achieve the contraction and approach or separation of the two ends of the ablation electrode 402 by moving the outer sheath tube 400 and the second pull tube 401.

[0076] In one embodiment, such as Figure 4 As shown, the first slider 301 includes a first insertion section 3011 and a first connecting section 3012. The first insertion section 3011 is adapted to the first sliding cavity 3001. A first limiting structure is provided between the first insertion section 3011 and the first sliding cavity 3001 to allow the first slider 301 to reciprocate linearly relative to the first connecting member 300. The outer diameter of the first connecting section 3012 is larger than the outer diameter of the first insertion section 3011. In the initial position, the first connecting section 3012 abuts against the first connecting member 300.

[0077] Specifically, such as Figure 2-4As shown, the first sliding cavity 3001 has a cylindrical barrel structure, and the first insertion section 3011 of the first slider 301 also has a matching cylindrical structure. The first limiting structure includes a first limiting boss 30111 disposed on the first insertion section 3011 of the first slider 301 and a first limiting groove 3002 disposed on the first connector 300. The first limiting boss 30111 is engaged in the first limiting groove 3002. The first limiting groove 3002 has a preset length, and its length direction is parallel to the central axis of the first sliding cavity 3001, thereby ensuring that the first slider 301 moves in a straight line.

[0078] Optionally, as a variation of the above embodiments, the first limiting groove 3002 may also be disposed on the first insertion section 3011 of the first slider 301, and the first limiting boss 30111 may be disposed on the inner wall of the first sliding cavity 3001.

[0079] Alternatively, the first sliding cavity 3001 and the first slider 301 can be configured as non-cylindrical irregular structures. For example, the cross-sections of the first insertion section 3011 and the first sliding cavity 3001 can be triangular, elliptical, or quadrilateral, etc., which can also enable the first slider 301 to move linearly only relative to the first connecting member 300.

[0080] Furthermore, a first slot 30122 is provided on the first connecting segment 3012 of the first slider 301, and the first slot 30122 is used for the insertion of the second slider 302. Specifically, the second slider 302 includes a second insertion segment 3021 and a second connecting segment 3022. The second insertion segment 3021 is adapted to the first slot 30122, and in this embodiment, both are cylindrical in shape. A second limiting structure is provided between the second insertion segment 3021 and the first connecting segment 3012, and the second limiting structure is used for the second slider 302 to move linearly relative to the first slider 301.

[0081] Specifically, the second limiting structure includes a second limiting boss 30211 disposed on the second insertion section 3021 of the second slider 302 and a second limiting groove 30123 disposed on the first connecting section 3012 of the first slider 301. The second limiting boss 30211 and the second limiting groove 30123 are adapted to each other. In this embodiment, the principle and structure of the second limiting structure are the same as those of the first limiting structure, as described above, and will not be repeated here.

[0082] Alternatively, the alternative to the second limiting structure has the same structural principle as the alternative to the first limiting structure, as mentioned above, and will not be elaborated further here.

[0083] In one embodiment, such as Figure 8-10 As shown, the present invention also provides an automated medical device, mainly comprising:

A first connecting part 50122 is provided on the first drive slider 5012, such as... Figure 11 and 12 As shown, the first connecting part 50122 can be detachably connected to the second slider 302. By setting the first driving slider 5012, the second slider 302 can be reciprocated linearly, which drives the third pull tube 3023 and the second pull tube 401 to move, thereby realizing the expansion and contraction of the ablation electrode 402.

Figure 12 As shown, when the first connector 300 is fixed on the first support cylinder 505, the position of the first pin 5022 corresponds to the position of the first clearance groove;

[0087] Furthermore, a first connecting hole 30121 is provided on the first slider 301, such as... Figure 4 As shown, the first pin 5022 can be inserted into the first connecting hole 30121 through the first clearance groove. Through the connection between the first connecting slider 502 and the first slider 301, the first connecting slider 502 drives the first slider 301 to move, thereby causing the first pull tube 3013 to drive the outer sheath tube 400 to move, realizing the automated delivery of the ablation electrode 402.

[0088] In one embodiment, to facilitate the movement control of the first driving slider 5012, a first support plate 5061 and a second support plate 5062 are provided in the second cavity. The first support plate 5061 and the second support plate 5062 divide the second cavity into a first space, a second space, and a third space. The first driving slider 5012 is disposed in the second space. A first lead screw 5011 and a first guide shaft 5013 are disposed between the first support plate 5061 and the second support plate 5062. The first lead screw 5011 is rotatably disposed on the first support plate 5061 and the second support plate 5062. The first guide shaft 5013 is fixedly disposed at both ends on the first support plate 5061 and the second support plate 5062, and the first lead screw 5011 and the first guide shaft 5013 are arranged in parallel. The first driving slider 5012 is movably sleeved on the first lead screw 5011 and the first guide shaft 5013. In this embodiment, there are two first guide shafts 5013. A first motor 501 is set in the third space. The output end of the first motor 501 is connected to the first lead screw 5011. The forward and reverse rotation of the first motor 501 drives the forward and reverse rotation of the first lead screw 5011, which in turn drives the first drive slider 5012 to move reciprocally in a linear motion.

[0089] Furthermore, the third space is equipped with a battery 5010 for driving the first motor 501. The battery 5010 is connected to the first motor 501, which enables the control handle 100 to operate without a power cord, so that it is not limited by the application environment.

[0090] In one embodiment, to enable the first connecting slider 502 to move linearly within the second cavity, a second guide shaft 5021 is provided within the second space. The two ends of the second guide shaft 5021 are fixed to the first support plate 5061 and the second support plate 5062. The second guide shaft 5021 and the first guide shaft 5013 are arranged parallel to each other. Figure 9-10 As shown, a first limiting slot is provided on the first support plate 5061. The width of the first limiting slot is adapted to that of the first connecting slider 502, so that the first connecting slider 502 and the inner wall of the first limiting slot abut against each other, and the abutting surface of the two is flat. Combined with the second guide shaft 5021, this restricts the first connecting slider 502 to reciprocating linear movement only within the second cavity. In the initial position, one end of the first connecting slider 502 is located in the first space, and the other end of the first connecting slider 502 passes through the first limiting slot and is located in the second space.

[0091] Alternatively, the limiting mechanism can be a straight-line convex structure or an irregular hole-shaft mating structure, so that the first connecting slider 502 only performs reciprocating linear movement.

[0092] In one embodiment, such as Figure 12 and Figure 14As shown, in order to fix the position of the first slider 301, a first threaded hole 5023 is provided on the first connecting slider 502, and a matching first rubber ring 50232 is provided in the first threaded hole 5023. At least one first rubber ring 50232 is provided, and a matching first threaded post 50231 is provided on the first threaded hole 5023. Specifically, during assembly, both the first threaded post 50231 and the first rubber ring 50232 are sleeved on the second guide shaft 5021. When the first threaded post 50231 rotates within the first threaded hole 5023, it can compress the first rubber ring 50232, thereby increasing the friction between the first connecting slider 502 and the second guide shaft 5021. This allows the first connecting slider 502 to keep the position of the first slider 301 relatively fixed relative to the first connecting member 300 without external force.

[0093] In one embodiment, to reduce the number of driving devices, a power connection is established between the first driving slider 5012 and the first connecting slider 502. Specifically, a retractable second pin 50121 is provided on the first driving slider 5012, such as... Figure 10 and Figure 12 As shown, a second connecting hole 5024 is provided on the first connecting slider 5012, and a second pin 50121 can be inserted into the second connecting hole 5024. At this time, when the first driving slider 5012 moves, it can drive the first connecting slider 502 to move synchronously, thereby realizing the synchronous movement of the first slider 301 and the second slider 302. When the second slider 302 needs to move alone, the second pin 50121 is removed from the second connecting hole 5024, and the first pin 5022 is inserted into the first connecting hole 30121 to fix the position of the first slider 301. At the same time, due to the provision of the first rubber ring 50232, the position of the first connecting slider 502 can be fixed without the action of external force, thereby realizing the fixed position of the first slider 302.

[0094] In one embodiment, such as Figure 15 As shown, to facilitate the fixing of the first connector 300 to the first support cylinder 505, the first support cylinder 505 is provided with a through first cylindrical channel. The first cylindrical channel is adapted to the shape of the insertion part of the first connector 300. The side wall of the first support cylinder 505 is provided with a first slot 5051 and a second slot 5052. The first connector 300 is provided with a first boss 3003. The first slot 5051 and the second slot 5052 are connected. The width of the first slot 5051 is adapted to the width of the first boss 3003, and the width of the second slot 5052 is adapted to the length of the first boss 3003. The second slot 5052 has a preset length. Figure 15 As shown, the length direction of the first boss is... Figure 15 In the left and right directions, the width of the first slot 5051 is... Figure 15 The width is oriented vertically. The first boss 3003 enters the second slot 5052 through the first slot 5051. Then, by rotating the first connector 300, the first boss 3003 enters the second slot 5052, thereby fixing the first connector 3003 onto the control handle 500 and preventing it from detaching from the control handle 500. In this embodiment, it should be noted that when the first connector 300 rotates to a certain angle and abuts against the inner wall of the second slot 5052, preventing further rotation, the position of the first clearance slot corresponds to the position of the first pin 5022, allowing the first pin 5022 to be inserted into the first connecting hole 30121 of the first slider 301. In this embodiment, the first slot 5051 and the second slot 5052 are perpendicularly distributed to each other.

[0095] In one embodiment, such as Figure 11-12 As shown, a first latch 503 and a first connecting channel 50123 are provided on the first connecting portion 50122 of the first driving slider 5012. In the initial state, the first latch 503 is located in the first connecting channel 50123. When subjected to external force, the first latch 503 can exit the first connecting channel 50123. In this embodiment, the first latch 503 exits the first connecting channel 50123 by rotation. A first slot 30221 adapted to the first latch 503 is provided on the second connecting section 3022 of the second slider 302. The first latch 503 can be engaged in the first slot 30221, thereby realizing the first driving slider 5012 driving the second slider 302 to move.

[0096] Furthermore, the first buckle 503 includes a first snap-fit ​​section 5032 and a first control section 5031. The first buckle 503 is rotatably mounted on the first connecting part 50122 via a first rotating shaft 50322. The thickness of the first snap-fit ​​section 5032 is adapted to the width of the first slot 30221, thereby maintaining a limit in the axial movement direction of the second slider 302, so that the first driving slider 5012 and the second slider 302 move synchronously. A first reset spring 5033 is provided on the first control section 5031. The first reset spring 5033 is used to reset the first latch 503 so that the first latch 503 is located in the first connecting channel 50123. On the other hand, when the first latching section 5032 is squeezed by external force, the first latch 503 rotates, thereby causing the second insertion section 3022 of the second slider 302 to be inserted into the first connecting channel 50123. At the same time, when the first slot 30221 corresponds to the position of the first latching section 5032, under the action of the first reset spring 5033, the first latching section 5032 is latched into the first slot 30221, thereby fixing the second slider 302 relative to the first driving slider 5012. In this embodiment, one end of the first reset spring 5033 is fixed to the far end of the first control segment 5031, and the other end of the first reset spring 5033 is fixed to the first connecting portion 50122. At the same time, the first reset spring 5033 is in a stretched state, applying a pulling force to the first control segment 5031 in the direction of the first connecting portion 50122, so that the first snap-fit ​​segment 5032 is located in the first connecting channel 50123.

[0097] Optionally, the other end of the first return spring 5033 can also be disposed on the housing of the control handle 500, that is, the first return spring 5033 can provide a force to the first control section 5031 in the direction of the first connecting part 50122, so that the first control section 5031 drives the first locking section 5032 to be located in the first connecting channel 50123.

[0098] In one embodiment, a first button 504 is movably mounted on the control handle 500. One end of the first button 504 abuts against the first control section 5031, and the first button 504 can drive the first latch 503 to rotate. A first limiting spring 5041 is sleeved on the first button 504. One end of the first limiting spring 5041 is connected to the housing of the control handle 500, and the other end of the first limiting spring 5041 is connected to the first button 504. In this embodiment, this is achieved by providing an annular boss on the first button 504, allowing the first button 504 to be movably mounted on the housing of the control handle 500 via the first limiting spring 5041. When the first button 504 is pressed, the first limiting spring is in a stretched state, and the first button 504 drives the first latch 503 to rotate around the first rotating shaft 50322, thereby causing the first latching section 5032 of the first latch 503 to exit the first latching groove 30221, thus disengaging the second slider 302 from the first driving slider 5012. In this embodiment, it should be noted that one end of the first button 504 is in non-pressure contact with the first control section 5031 of the first latch 503. When the first button 504 is not pressed, the first button 504 does not exert force on the first latch 503, so as to facilitate the movement of the first latch 503 relative to the first button 504.

[0099] Furthermore, in order to facilitate the snap-fit ​​and fixation of the first buckle 503 and the second slider 302, a first guide surface 50321 is provided on the side of the first snap-fit ​​section 5032 of the first buckle 503 near the second slider 302 and / or a second guide surface 30222 is provided on the second connecting section 3022 of the second slider 302, thereby realizing the quick connection between the second slider 302 and the first drive slider 5012.

[0100] Specifically, both the first guide surface 50321 and the second guide surface 30222 are inclined surfaces, such as... Figure 13 As shown, the first guide surface 50321 and the second guide surface 30222 are inclined towards the second slider 302 at a certain angle. In this embodiment, the larger the inclination angle of the first guide surface 50321 and the second guide surface 30222, the smaller the resistance encountered during the advancement of the first connector 300. It should be particularly noted that when the first boss 3003 on the first connector 300 is advancing in a straight line, and the first boss 3003 abuts against the inner wall of the slot 5051 and the second slot 5052, the first buckle 503 and the first slot 30221 are just engaged.

[0101] Optionally, the first guide surface 50321 and the second guide surface 30222 can be a combination of an inclined surface and a circular arc surface. As a preferred embodiment, the first guide surface 50321 and the second guide surface 30222 are parallel to each other, thereby further reducing the resistance during the advancement of the first connector 300.

[0102] Alternatively, the second guide surface 30222 can be provided only on the second slider 302 or the first guide surface 50321 can be provided only on the first buckle 503, and the above purpose can be achieved in the same way.

[0103] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
