Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular refers to a medical component for automated operation and a medical device 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. Summary of the Invention

[0067] 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.

[0068] In one embodiment, such as Figure 1 , Figure 14and Figure 16 As shown, this invention provides an automated medical device, which mainly includes:

[0069] The handle body 300 has a first cavity, and a first connector 308 is provided at one end of the handle body 300. The first connector 308 is connected to a matching instrument, such as an endoscope or a robot channel.

[0070] The first connector 108 is detachably connected to an external control device. In this embodiment, the first connector 108 is detachably mounted on the control handle 100, and the first connector 108 is provided with a first sliding cavity. In this embodiment, the mating part of the first connector 108 and the control handle 100 is a cylindrical structure, which can be plugged into and snapped onto the control handle 100, and the first connector 108 can rotate relative to the control handle 100.

[0071] The first slider 109 is movably disposed in the first slide cavity of the first connector 108 and moves back and forth linearly within the first slide cavity. The first slider 109 is provided with a first connecting hole 1093 for driving the first slider 109 to move linearly. In this embodiment, the first slider 109 only moves back and forth linearly relative to the length direction of the first slide cavity, and the first slider 109 is adapted to the shape of the first slide cavity.

[0072] The first conduit 200 has one end connected to the handle body 300 and the other end connected to the first connector 108. A first channel 201 is provided on the first conduit 200, which connects the first cavity of the handle body 300 and the first sliding cavity of the first connector 108. Furthermore, a PTFE liner 203 is provided within the first channel 201. Figure 17 As shown, this reduces the frictional resistance between the first pull tube 306 and the first conduit 200.

[0073] The outer sheath tube 400 has a second channel that passes through both ends of itself. The outer sheath tube 400 is movably disposed at one end of the first connector 308 of the handle body 300. One end of the outer sheath tube 400 extends into the first cavity of the handle body 300, and the outer sheath tube 400 can reciprocate relative to the handle body 300 along its own axis.

[0074] An ablation electrode, located at the distal end of the outer sheath, is electrically connected to an external energy generator and configured to ablate tissue using ablation energy. In this embodiment, the ablation electrode has a cylindrical structure, with its outer diameter and the outer diameter of the outer sheath both having pointed tips for puncturing lesions. In this embodiment, a first connector allows for a detachable connection between the entire medical component and the external control structure, enabling the reciprocating linear movement of the first slider. This, in turn, drives the outer sheath relative to the handle body via the first pull tube, thus achieving precise delivery of the ablation electrode.

[0075] In one embodiment, a first pull tube 306 is further included, which is movably inserted into the first channel 201 of the first conduit 200 and movably sleeved on the control wire 1107. One end of the first pull tube 306 is connected to the outer sheath tube 400, and the other end of the first pull tube 306 is connected to the first slider 109. By moving the first slider 109, the outer sheath tube 400 is moved relative to the handle body 300.

[0076] In one embodiment, the first conduit 306 is provided with a third channel 202 connecting the first sliding cavity and the first cavity. The third channel 202 and the first channel 201 are independent of each other. A first wire 307 is provided in the third channel 202. One end of the first wire 307 is electrically connected to the ablation electrode 500 through a second channel, and the other end of the first wire 307 extends out of the first connector 108 and forms a first plug 3071. The first wire 307 is used to deliver external energy to the ablation electrode 500.

[0077] Furthermore, since the outer sheath 400 will move relative to the handle body 300, in order to avoid pulling on the first wire 307 during the movement, or to prevent the first wire 307 from having excess length inside the handle body 300, the first wire 307 is divided into two segments: the first wire 307 located in the second channel is the second segment, and the first wire 307 located in the third channel 202 is the first segment, which are electrically slidably connected inside the handle body.

[0078] Specifically, a first bridge connector 304, a second bridge connector 303, and a third bridge connector 305 are provided inside the handle body 300. The first bridge connector 304 is connected to the outer sheath tube 400, the third bridge connector 305 is connected to the first pull tube 306, and both ends of the second bridge connector 303 are connected to the first bridge connector 304 and the third bridge connector 305, respectively. The second bridge connector 303 slides within the handle body 100. Multiple third support plates 301 are provided inside the handle body 100, and each third support plate 301 has a matching groove. The second bridge connector 303 can... The sliding mechanism reciprocates linearly on the grooves of multiple third support plates 301. The second bridge pipe 303 is a rigid structure with a large outer diameter to ensure the stability of its sliding structure. The outer diameter of the second bridge pipe 303 is larger than that of the first bridge pipe 304 and the third bridge pipe 305. The outer diameter of the third bridge pipe 305 is larger than that of the first pull tube 306. The outer diameter of the first bridge pipe 304 is larger than that of the outer sheath tube 400. Since the outer diameters of the outer sheath tube 400 and the first pull tube 306 are relatively small, this type of structure is designed for transition while ensuring the stability of the sliding of the second bridge pipe 303.

[0079] It should be noted that the first bridge connector 304, the second bridge connector 303, and the third bridge connector 305 are coaxially arranged. Furthermore, a conductive spring 3031 is provided on the second bridge connector 303. The conductive spring 3031 is made of a conductive metal material. A first conductive plate 302 of a certain length is provided inside the handle body 300. A first wire 307 located in the third channel 202 is fixedly connected to the first conductive plate 302. The first wire 307 located in the second channel is connected to the conductive spring 3031. The conductive spring 3031 slides against the first conductive plate 302, and when the conductive spring 3031 abuts against the first conductive plate 302, it is in a compressed state, thereby ensuring the stability of the electrical connection between the conductive spring 3031 and the first conductive plate 302.

[0080] Optionally, the first conductor 307 may also be embedded inside the outer sheath 400 or a separate channel may be provided for the insertion of the first conductor 307.

[0081] In one embodiment, a second slider 110 is further included, which is movably disposed in the first sliding cavity of the first connector 108. The second slider 110 can be detachably connected to the first connecting part 1031 of the first drive slider 103. A second connecting hole 1103 is provided at one end of the second slider 110 near the first slider 109. The second connecting hole 1103 can correspond to the position of the first connecting hole 1093, and the first connecting hole 1093 is located outside the second connecting hole 1103.

[0082] Furthermore, it also includes control wire 1107, such as Figure 18 As shown, the control wire 1107 is movably inserted into the second channel of the outer sheath tube 400. One end of the control wire 1107 is connected to the first end of the ablation electrode 500. The other end of the control wire 1107 passes through the second channel, the handle body 300, the first channel 201, and the first slider 109, and is connected to the second slider 110. In this embodiment, a through hole 1092 is provided on the first slider 109, so that the control wire 1107 passes through the first slider 109 and connects to the second slider 110.

[0083] In one embodiment, an ablation electrode 500 is disposed at the end of the outer sheath away from the handle body 300, such as... Figure 15 As shown, the ablation electrode 500 has a first end and a second end, which can be configured with ablation energy, such as pulse energy. The ablation electrode 500 is an expandable structure. One end of the outer sheath 400 is connected to the second end of the ablation electrode 500, and one end of the control wire 1107 is connected to the first end of the ablation electrode 500. By moving the control wire 1107 relative to the outer sheath 400, the first end and the second end of the ablation electrode 500 are brought together, thereby expanding the ablation electrode 500. In this embodiment, the ablation electrode 500 is a basket weave structure, and its shape can be cylindrical, spindle-shaped, or spherical.

[0084] Optionally, the ablation electrode 500 can be a columnar structure, which is directly connected to one end of the control wire 1107. By moving the control wire 1107, the ablation electrode 500 can be housed or extended out of the outer sheath 400.

[0085] In one embodiment, to ensure that the first slider 109 and the second slider 110 only reciprocate linearly relative to the first connecting member 108, a first limiting structure is provided between the first slider 109 and the first connecting member 108, or between the second slider 110 and the first connecting member 108, or both the first slider 109 and the second slider 110 are simultaneously provided with the first connecting member 108. The first limiting structure is used for the first connecting member 108 to drive the first slider 109 and / or the second slider 110 to rotate synchronously. In this embodiment, the first slider 109 and the second slider 110 are engaged and can rotate synchronously, hence the first limiting structure is provided between the first slider 109 and the first connecting member 108.

[0086] Furthermore, such as Figure 3 and Figure 4 As shown, the first limiting structure includes a first limiting boss 1091 disposed on the first slider 109 and a first limiting groove 1082 disposed on the first connector 108, wherein the first limiting groove 1082 is distributed along the axial direction of the first connector 108, and the first limiting boss 1091 is engaged in the first limiting groove 1082.

[0087] Alternatively, the first limiting boss 1091 can be disposed on the inner wall of the first connector 108, and a corresponding first limiting groove 1082 can be disposed on the first slider 109.

[0088] Alternatively, the first limiting boss 1091 and the first limiting groove 1082 may be provided only between the second slider 110 and the first connector 108; or the first limiting boss 1091 and the first limiting groove 1082 may be provided simultaneously between the first connector 108 and the first slider 109 and the second slider 110.

[0089] Furthermore, to ensure that the first slider 109 and the second slider 110 can rotate synchronously, and that the positions of the first connecting hole 1093 and the second connecting hole 1103 correspond, a first fitting part is provided between the first slider 109 and the second slider 110. Specifically, a first fitting boss 1094 is provided on the first slider 109, and a second fitting boss 1104 is provided on the second slider 110. The first connecting hole 1093 is provided on the first fitting boss 1094, and the second connecting hole 1103 is provided on the second fitting boss 1104. The first mating boss 1094 can abut against the second mating boss 1104, thereby preventing relative rotation between the first slider 109 and the second slider 110. When the first mating boss 1094 and the second mating boss 1104 are fully abutted, the positions of the first connecting hole 1093 and the second connecting hole 1103 are aligned and their central axes coincide, thereby facilitating the insertion of the first pin 1061 into the first connecting hole 1093 and the second connecting hole 1103.

[0090] Alternatively, the contact surfaces between the first slider 109, the second slider 110 and the first connector 108 can be set to non-rotational irregular shapes, such as triangular, quadrilateral or elliptical contact cross-sections.

[0091] In one embodiment, such as Figure 2 - Figure 5 As shown, an automated medical device provided by the present invention mainly includes a control handle 100, a first drive slider 103, a first connecting slider 106, a first support cylinder 107, and a consumable handle for automated operation in the above embodiments.

[0093] The first drive slider 103 is movably disposed within the second cavity of the control handle 100. The first drive slider 103 reciprocates linearly within the second cavity, such as... Figure 6 As shown, a first connecting part 1031 is provided on the first driving slider 103; in this embodiment, the first driving slider 103 can be moved by electric or hydraulic driving force.

[0094] The first connecting slider 106 is movably disposed within the second cavity, wherein the first connecting slider 106 can reciprocate linearly within the second cavity, and its movement direction is consistent with that of the second slider 110. A retractable first pin 1061 is provided on the first connecting slider 106, such as... Figure 8As shown, when the first pin 1061 is only inserted into the first connecting hole 1093, the position of the first slider 109 can be fixed or moved relative to the first connector 108. When the first pin 1061 is inserted into both the first connecting hole 1093 and the second connecting hole 1103, the first slider 109 and the second slider 110 can move or be fixed synchronously. When the first pin 1061 is not inserted into either the first connecting hole 1093 or the second connecting hole 1103, the first connector 108 can be rotated relative to the control handle 100 for adjustment.

[0095] To facilitate the detachable connection between the first connector 108 and the control handle 100, a first support cylinder 107 is provided on the control handle 100. One end of the first support cylinder 107 is fixed to the first support plate 1001, and the other end of the first support cylinder 107 is fixed to the outer shell of the control handle 100.

[0096] Specifically, such as Figure 10 and Figure 11 As shown, the first support cylinder 107 has a through first cylindrical channel, which is adapted to the shape of the first connector 108, so that the first connector 108 can rotate relative to the first support cylinder 107 and reciprocate linearly along its axis. The first support cylinder 107 has a first slot 1072 and a second slot 1073, and the first connector 108 has a first boss 1083. The first slot 1072 and the second slot 1073 are connected. The first slot 1072 is distributed along the axial direction of the first support cylinder 107, and the second slot 1073 is located on the side wall of the first support cylinder 107 and is a through structure. The width of the first connector 108 is the same as the width of the first boss 1083, so that the first boss 1083 can enter the second slot 1073 through the first slot 1072. The width of the second slot 1073 is adapted to the length of the first boss 1083, and the second slot 1073 has a preset length. After the first boss 1083 enters the second slot 1073, the first connector 108 is rotated to make the first boss 1083 and the first slot 1072 misaligned, thereby axially limiting and fixing the first boss 1083, so that the first boss 1083 is engaged in the second slot 1073, thereby fixing the relative position of the first connector 108 and the first support cylinder 107.

[0097] Furthermore, the first support cylinder 107 is provided with a first clearance groove 1071 distributed along its own axis, and the first connector 108 is provided with a second clearance groove 1081 distributed along its own axis. The first connecting hole 1093 and the second connecting hole 1103 are both positioned corresponding to the second clearance groove 1081. The first clearance groove 1071 is positioned corresponding to the first pin 1061. When the first boss 1083 rotates to its limit position within the second groove 1073, the first clearance groove 1071 and the second clearance groove 1081 are positioned corresponding. At this time, the first pin 1061 can be inserted into the first connecting hole 1093 and the second connecting hole 1103. The limit position mentioned in this embodiment is when the first boss 1083 abuts against each other in the radial direction of the first support cylinder 107 and cannot rotate.

[0098] In one embodiment, in order to achieve a detachable connection between the second slider 110 and the first connecting portion 1031 of the first driving slider 103, a second fitting portion is provided between the second slider 110 and the first connecting portion 1031, wherein the second fitting portion is used for the second slider 110 and the first driving slider 103 to perform synchronous reciprocating linear movement.

[0099] Specifically, the second fitting part includes a second boss disposed on the second slider 110 and a third slot and a fourth slot 1034 disposed on the first connecting part 1031. The third slot and the fourth slot 1034 are connected. The third slot is adapted to the shape of the second boss, so that the second boss passes through the third slot and enters the fourth slot 1034. The fourth slot 1034 has a preset length in the radial direction of the first connecting part 1031 of the cylindrical structure.

[0100] The second boss includes a rotating part 1101 and a limiting part 1102, and the third slot includes a rotating groove 1032 and a limiting groove 1033. The rotating part 1101 of the second boss corresponds to the rotating groove 1032 of the third slot, and the limiting part 1102 of the second boss corresponds to the limiting groove 1032 of the third slot. The thickness of the limiting part 1102 of the second boss matches the width of the fourth slot 1034, thereby ensuring that the second boss is engaged with the fourth slot 1034, thus achieving axial limiting between the two. At the same time, the second boss does not protrude from the outer wall of the first connecting part 1031, which facilitates the rotation of the second slider 110 and avoids motion interference. It should be noted that the angle through which the second boss rotates in the fourth slot 1034 is consistent with the angle through which the first boss 1083 rotates in the second slot 1073, thereby ensuring that the first boss 1083 and the second boss rotate synchronously to the limit position. The limit position is as described above and will not be elaborated further here.

[0101] In one embodiment, the detachable connection between the first drive slider 103 and the second slider 110 can also be a snap-fit ​​connection, such as... Figure 20-22 As shown, a first latch 503 and a first connecting channel 1031 are provided on the first connecting portion 1031 of the first driving slider 103. In the initial state, the first latch 503 is located in the first connecting channel 10311. When subjected to external force, the first latch 503 can exit the first connecting channel 10311. In this embodiment, the first latch 503 exits the first connecting channel 10311 by rotation. A first slot 1105 adapted to the first latch 503 is provided on the second slider 110. The first latch 503 can be engaged in the first slot 1105, thereby realizing that the first driving slider 103 drives the second slider 110 to move.

[0102] 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 side wall of the first connecting part 1031 via a first rotating shaft 50322. The thickness of the first snap-fit ​​section 5032 is adapted to the width of the first slot 1105, thereby keeping it in a limited position in the axial movement direction of the second slider 110, so that the first driving slider 103 and the second slider 110 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 10311. 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 110 to be inserted into the first connecting channel 10311. At the same time, when the first slot 1105 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 1105, thereby fixing the second slider 110 relative to the first driving slider 103. 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 1031. 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 1031, so that the first snap-fit ​​segment 5032 is located in the first connecting channel 10311.

[0103] In one embodiment, a first button 504 is movably mounted on the control handle 100. 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 100, 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. The first button 504 can be movably mounted on the housing of the control handle 100 through 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 latch slot 1105, so as to disengage the second slider 110 from the first driving slider 103. 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.

[0104] Furthermore, in order to facilitate the snap-fit ​​and fixation of the first buckle 503 and the second slider 110, 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 110 and / or a second guide surface 1106 is provided on the second slider 110, thereby realizing the quick connection between the second slider 110 and the first drive slider 103.

[0105] Specifically, both the first guide surface 50321 and the second guide surface 1106 are inclined surfaces, such as... Figure 22 As shown, the first guide surface 50321 and the second guide surface 1106 are inclined towards the second slider 110 at a certain angle. In this embodiment, the larger the inclination angle of the first guide surface 50321 and the second guide surface 1106, the smaller the resistance encountered during the advancement of the first connector 108. It should be particularly noted that when the first boss 1083 on the first connector 108 is advancing in a straight line, and the first boss 1083 abuts against the inner wall of the first slot 1072 and the second slot 1073, the first buckle 503 and the first slot 1105 are just engaged.

[0106] In one embodiment, to facilitate the movement control of the first driving slider 103, a first support plate 1001 and a second support plate 1002 are provided in the second cavity. The first support plate 1001 and the second support plate 1002 divide the second cavity into a first space, a second space, and a third space. The first driving slider 103 is disposed in the second space. A first lead screw 102 and a first guide shaft 104 are disposed between the first support plate 1001 and the second support plate 1002. The first lead screw 102 is rotatably disposed on the first support plate 1001 and the second support plate 1002. The first guide shaft 104 is fixedly disposed at both ends on the first support plate 1001 and the second support plate 1002, and the first lead screw 102 and the first guide shaft 104 are arranged in parallel. The first driving slider 103 is movably sleeved on the first lead screw 102 and the first guide shaft 104. In this embodiment, there are two first guide shafts 104. A first motor 101 is set in the third space. The output end of the first motor 101 is connected to the first lead screw 102. The forward and reverse rotation of the first motor 101 drives the forward and reverse rotation of the first lead screw 102, thereby driving the first drive slider 103 to move reciprocally in a linear motion.

[0107] Furthermore, the third space is equipped with a battery 1011 for driving the first motor 101. The battery 1011 is connected to the first motor 101, which enables the control handle 100 to operate without a power cord, so that it is not limited by the application environment.

[0108] In one embodiment, to enable the first connecting slider 106 to move linearly within the second cavity, a second guide shaft 105 is provided within the second space. The two ends of the second guide shaft 105 are fixed to the first support plate 1001 and the second support plate 1002, wherein the second guide shaft 105 and the first guide shaft 104 are arranged parallel to each other. Figure 12 As shown, a first limiting slot 10011 is provided on the first support plate 1001. The width of the first limiting slot 10011 is adapted to the width of the first connecting slider 106, so that the first connecting slider 106 and the inner wall of the first limiting slot 10011 abut against each other, and the abutting surface of the two is a plane. Combined with the second guide shaft 105, the first connecting slider 106 is restricted to reciprocating linear movement only in the second cavity.

[0109] Alternatively, the limiting can be achieved through a straight-line convex structure or an irregular hole-shaft mating structure, so that the first connecting slider 106 only performs reciprocating linear movement.

[0110] In one embodiment, such as Figure 8 and Figure 9As shown, in order to fix the position of the first slider 109, a first threaded hole is provided on the first connecting slider 106, and a matching first rubber ring 1064 is provided in the first threaded hole. The number of first rubber rings 1064 is at least one, and a matching first threaded post 1063 is provided on the first threaded hole. Specifically, during assembly, both the first threaded post 1063 and the first rubber ring 1064 are sleeved on the second guide shaft 105. When the first threaded post 1063 rotates in the first threaded hole, it can compress the first rubber ring 1064, thereby increasing the friction between the first connecting slider 106 and the second guide shaft 105. This allows the first connecting slider 106 to keep the position of the first slider 109 relatively fixed relative to the first connecting member 108 without being driven by an external force.

[0111] In one embodiment, to reduce the size of the drive control and the control handle 100, a power connection can be made between the first connecting slider 106 and the first driving slider 103, so that the first driving slider 103 drives the first connecting slider 106 to move synchronously. Specifically, as shown in the figure... Figure 7 As shown, in this embodiment, a retractable second pin 1035 is provided on the first driving slider 103, and a third connecting hole 1062 is provided on the first connecting slider 106. The second pin 1035 can be inserted into or disengaged from the third connecting hole 1062. When the second pin 1035 is inserted into the third connecting hole 1062, the first connecting slider 106 and the first driving slider 103 can move synchronously. When the second pin 1035 disengages from the third connecting hole 1062, the first connecting slider 106 is fixed in position, and the first driving slider 103 moves independently, thereby driving the second slider 110 to move independently. In this embodiment, the first pin 1061 and the second pin 1035 have the same structure, both being telescopic mechanisms of electric push rods controlled by electric drive. This is existing technology and will not be described in detail here.

[0112] Alternatively, as another variation of this embodiment, the third connecting hole 1062 can be disposed on the first driving slider 103, and the second pin 1035 can be disposed on the first connecting slider 106, which can also achieve the above purpose.

[0113] In one embodiment, for ease of operation, an operation button 1003 is provided on the control handle 100, such as... Figure 19 As shown, the operation button 1003 is equipped with operation labels. Operators perform corresponding operations according to the operation labels to expand or contract the ablation electrode 500 and to move the outer sheath 400 forward or backward. The reset button is mainly used to keep the ablation electrode 500 in its initial state, preventing the ablation electrode 500 from moving within the body cavity when it is not contracted in its expanded state.

[0114] Furthermore, in one embodiment, such as Figure 12 and Figure 13 As shown, a first position sensing component and a second position sensing component are provided inside the control handle 100. The first position sensing component is mainly used to detect the position of the first driving slider 103 within the control handle 100 to prevent the first driving slider 103 from moving beyond its travel range. The second position sensing component is mainly used to detect whether the ablation electrode 500 is in its initial state. Before and after surgical ablation, it is generally necessary to reset the ablation electrode 500 to its initial state, which facilitates movement within the body cavity and avoids damage to the body cavity due to untimely contraction. The initial state is that the first driving slider 103 is in the position shown in the diagram. Figure 13 The leftmost position is shown. Specifically, the first position sensing component includes a first photocoupler 1004, a second photocoupler 1005, and a first photosensitive baffle 1067. The first photocoupler 1004 and the second photocoupler 1005 are located near the first support plate 1001 and the second support plate 1002, respectively. The first photosensitive baffle 1067 is located on the first connecting slider 106 and reciprocates between the first photocoupler 1004 and the second photocoupler 1005. The second position sensing component includes a third photosensitive baffle 1065 disposed on the first connecting slider 106 and a third photocoupler 1036 disposed on the first driving slider 103, as shown. Figure 7 As shown, it is mainly used to confirm whether the first drive slider 103 is in the initial position, that is, the ablation electrode 500 is in the contracted state.

[0115] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.
