[0002] Endoscopic submucosal dissection is a new treatment method that has emerged in recent years. It is also a technology with great clinical application prospects. It allows more early gastrointestinal cancers to be completely removed at one time under endoscopy, eliminating the pain of open surgery and organ resection.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] The core of the present invention is to provide a two-in-one therapeutic device, which can realize the switching use of two devices, is simple to operate and convenient to use, and has high flexibility.

[0053] Please refer to Figures 1 to 11 The present application provides a two-in-one therapeutic instrument, which is mainly used for endoscope and other detection and treatment processes. The proximal end in the present application refers to the operating side of the therapeutic instrument, and the distal end refers to the side close to the affected area. Correspondingly, the proximal end of each component is the side close to the operating side of the component, and the distal end of each component is the side close to the affected area.

[0054] The above-mentioned therapeutic device includes a first device 5 and a second device 6 that can be extended and retracted along the axial direction, and a handle that can operate the first device 5 and the second device 6. The handle includes: a main body 1, an elastic member 7, a handle slider 2, a first slider 3 and a second slider 4.

[0055] The handle slider 2, first slider 3, and second slider 4 are all axially slidably disposed on the main body 1. The first slider 3 is connected to the first instrument 5 via a first operating wire 5a, and the second slider 4 is connected to the second instrument 6 via a second operating wire 6a. It should be noted that the first operating wire 5a and the second operating wire 6a should be rigid and capable of both pushing and pulling operations.

[0056] In the present application, the first instrument 5 and the second instrument 6 are instruments for treatment or detection, wherein when the first instrument 5 is extended toward the distal end, it can be used to achieve its function, and when the second instrument 6 moves toward the proximal direction, it can move to its working position to achieve its work, or because the second instrument 6 moves toward the proximal end, the third instrument 10 located at the distal end is exposed, and the work of the third instrument 10 can be achieved.

[0057] In the initial state, the handle slider 2 is located in the middle of the main body 1 (i.e. the initial position, refer to Figure 1 ), the first slide block 3 and the second slide block 4 are respectively located at their initial positions, and the first instrument 5 and the second instrument 6 are located at the distal end. Neither the first instrument 5 nor the second instrument 6 is in the working position.

[0058] The movement of the handle slider 2 along the axial direction toward the distal end can be used to push the first operating wire 5a to move distally, so as to push the first slider 5 connected thereto to move distally. The movement of the handle slider 2 along the axial direction toward the proximal end can be used to push the second operating wire 6a to move proximally, so as to push the second slider 6 connected thereto to move proximally.

[0059] Specifically, when the handle slider 2 pushes the first slider 3 distally, the first operating wire 5a is connected to the first slider 3, causing the first operating wire 5a to move distally, and the first instrument 5 is pushed to the first instrument working position, the second slider 4 is abutted by the main body 1 to limit its distal movement, and the elastic member 7 limits the proximal movement of the second slider 3. In this state, the second slider 4 cannot move distally due to the abutment, and cannot move freely proximally due to the elastic force of the elastic member 7. Therefore, it can maintain its abutment position with the main body 1, ensuring its position stability.

[0060] It should be noted that, in this state, the elastic member 7 also exerts an elastic force on the first slider 3 , so as to drive the first slider 3 to reset when the pushing force of the handle slider 2 is cancelled.

[0061] At this time, if the handle slider 2 moves proximally to return to the middle position, the first slider 3 will be affected by the elastic force of the elastic member 7 and move back to the initial position, driving the first operating wire 5a to return to the initial position, thereby driving the first instrument 5 to move from the first instrument working position to the proximal direction to its corresponding initial position.

[0062] When the handle slider 2 pushes the second slider 4 proximally, the second operating wire 6a connected to the second slider 4 causes the second operating wire 6a to move proximally, thereby pushing the second instrument 6 proximally to the second instrument working position. The first slider 3 is abutted by the main body 1 to limit its proximal movement, and the elastic member 7 limits the distal movement of the first slider 4. In this state, the first slider 3 cannot move proximally due to the abutment, and cannot move freely distally due to the elastic force of the elastic member 7. Therefore, it can maintain its abutment position with the main body, ensuring its position stability.

[0063] It should be noted that, in this state, the elastic member 7 also exerts an elastic force on the second slider 4 , so as to drive the second slider 4 to reset when the pushing force of the handle slider 2 is cancelled.

[0064] At this time, if the handle slider 2 moves distally to return to the middle position, the second slider 4 is acted upon by the elastic force of the elastic member 7 and moves back to the initial position, driving the second operating wire 6a to return to the initial position, thereby driving the second instrument 6 to move distally from the second instrument working position to its corresponding initial position.

[0065] During use of the above structure, if the first instrument 5 is to be used, the handle slider 2 is controlled to move distally, allowing the first instrument 5 to be extended and placed in its working position without causing the second instrument 6 to extend outward, and keeping the second instrument 6 in a stable state. After the first instrument 5 is used, the handle slider 2 can be controlled to return (move proximally), causing the first instrument 5 to return to its original position.

[0066] If the second instrument 6 is to be used, the handle slider 2 is controlled to move proximally, so that the second instrument 6 moves a certain distance proximally and is in its working position, without causing the first instrument 5 to extend outward, and the first instrument 5 is kept in a stable state. After the second instrument 6 is used, the handle slider 2 can be controlled to return to its original position to drive the second instrument 6 to return to its original position.

[0067] The above-mentioned operation method is simple. The handle slider 2 can drive the two instruments to work in segments and time periods without affecting each other. The movement of the handle slider 2 in two directions respectively realizes the work of different instruments, which can make the operation of instrument switching simpler, the action is coherent, and the use is more convenient and reliable, which can reduce the probability of switching errors during surgery.

[0068] In the specific embodiment of this application, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The main body 1 is provided with a limiting structure for limiting the movement of the first slider 3 toward the proximal end and a limiting structure for limiting the movement of the second slider 4 toward the distal end. Specifically, the main body 1 is provided with a first limiting surface and a second limiting surface. The first slider 3 is located on the distal side of the handle slider 2, and the second slider 4 is located on the proximal side of the handle slider 2.

[0069] The first slider 3 and the second slider 4 are respectively located on either side of the handle slider 2 and each has a connection portion for correspondingly connecting to the first instrument 5 and the second instrument 6. The connection portion can specifically be a first operating wire 5a and a second operating wire 6a. The two ends of the first operating wire 5a connect the first slider 3 and the first instrument 5, and the two ends of the second operating wire 6a connect the second slider 4 and the second instrument 6. Alternatively, the connection portion can also be other rigid connection structures that can facilitate axial push-pull operations.

[0070] The first limiting surface 11 faces the distal end and is used to limit the first slider 3 from moving toward the proximal end; the second limiting surface 12 faces the proximal end and is used to limit the second slider 4 from moving toward the distal end;

[0071] A through hole 21 or a through groove is provided between the proximal side and the distal side of the handle slider 2. Since the handle slider 2 is located between the second slider 4 and the second instrument 6, the second slider 4 needs to be provided with a structure for connecting to the second instrument 6, and the connection part between the second slider 4 and the second instrument 6 passes through the through hole 21 or the through groove.

[0072] It should be noted that the arrangement of the first limiting surface 11 and the second limiting surface 12 provided in this embodiment, as well as the scheme of providing a through hole 21 or a through groove between the proximal side and the distal side of the handle slider 2, can be combined with any other embodiment of the present application, for example Figures 6 to 8 In the three embodiments shown, the above-mentioned limiting surface and through hole 21 can be provided.

[0073] Optionally, the connecting portion includes a second operating wire 6 a connecting the second slider 4 and the second instrument 6 , or may be other structures.

[0074] Based on the above examples, please refer to Figure 6 , Figure 6 This is a cross-sectional view of the initial state of the second specific embodiment provided by the present invention.

[0075] The elastic member 7 specifically includes a first elastic member 71 and a second elastic member 72. The two elastic members are used to respectively control the first slider 3 and the second slider 4.

[0076] The first elastic member 71 is provided between the distal wall of the main body and the first slider 3. When the handle slider 2 pushes the first slider 3 toward the distal end, the first elastic member 71 is compressed.

[0077] The second elastic member 72 is provided between the proximal wall of the main body and the second slider 4 . When the handle slider 2 pushes the second slider 4 toward the proximal end, the second elastic member 72 is compressed.

[0078] The main body 1 provided in this application should be a structure with an inner cavity. The above-mentioned distal wall refers to the inner wall of the main body 1 located at the distal end, and the inner wall faces the handle slider 2. The proximal wall refers to the inner wall of the main body located at the proximal end, and the inner wall faces the handle slider 2.

[0079] In addition, the compression of the first elastic member 71 means that the first elastic member 71 is in a compressed state and is continuously compressed, but does not rule out the possibility that the first elastic member 71 is in a compressed state at other times or in other states. The same applies to the second elastic member 72 .

[0080] Please refer to Figure 7 and Figure 8 , Figure 7 This is a cross-sectional view of the initial state of the third specific embodiment provided by the present invention. Figure 8 This is a cross-sectional view of the initial state of the fourth specific embodiment provided by the present invention.

[0081] Two ends of the elastic member 7 are fixedly connected to the first slider 3 and the second slider 4 respectively. The elastic member 7 is located in the through hole 21 or the through groove.

[0082] When the handle slider 2 moves distally, it pushes the first slider 3 to move distally. However, the second slider 4 is restrained by the second limiting surface 12 and cannot move distally. Therefore, the elastic member 7 is stretched, and can simultaneously apply a proximal force to the first slider 3 and a distal force to the second slider 4. During the retraction process of the handle slider 2, these two elastic forces can be maintained until it is completely retracted to the intermediate position.

[0083] When the handle slider 2 moves toward the proximal end, it pushes the second slider 4 toward the distal end. However, since the first slider 3 is restricted from moving toward the proximal end by the first limiting surface 11, the elastic member 7 is stretched, which can simultaneously apply a force toward the original end to the second slider 4 and a force toward the proximal end to the first slider 3. During the retraction process of the handle slider 2, these two elastic forces can still be maintained until it is completely retracted to the intermediate position.

[0084] In addition, when the handle slider 2 is in the middle position, the elastic member 7 can be in a compressed state, but is preferably in a stretched state or a balanced state. The stretched state can best utilize the elastic force of the elastic member 7. When the handle slider 2 moves in any direction, the elastic member 7 can keep the two sliders in a stable state, and the first device 5 or the second device 6 will not become unstable due to overall accidental shaking.

[0085] Please refer to Figures 1 to 5 A distal slider 42 is provided at the distal end of the handle slider 2. The distal slider 42 is connected to the second slider 4 through a rod 41. The rod 41 passes through the through hole 21 or the through groove to fix the second slider 4 and the distal slider 42.

[0086] The distal slider 42 is connected to the second instrument 6 via the second operating wire 6 a . The distal slider 42 is located at the distal end of the first slider 3 . Both ends of the elastic member 7 abut against the first slider 3 and the distal slider 42 , respectively.

[0087] The through hole 21 or through slot is arranged axially, and the end of the rod 41 near the distal end is connected to the distal slider 42, so as to save the radial dimension of the main body 1 and achieve volume control. In addition, the through hole 21 or through slot can also guide the movement of the rod 41 and the handle slider 2.

[0088] The rod 41 connects the second slider 4 with the distal slider 42. It can be understood that the end of the rod 41 has a radial protrusion, which is the second slider 4; the second slider 4 can be selectively clamped to the proximal side of the main body 1 or the handle slider 2. In the initial state, the second slider 4 can be clamped to the main body 1 to limit movement toward the distal end. When the handle slider 2 moves toward the proximal end, it will clamp the second slider 4 to drive the rod 41 to move toward the proximal end.

[0089] It should be noted that the main body 1 can have a cavity, in which the first and second sliders 3 and 4 can be disposed. Alternatively, the main body 1 can be a plate structure, with the first and second sliders 3 and 4 disposed thereon. In this embodiment, the first and second sliders 3 and 4 are located on either side of the handle slider 2, and the second slider 4 is connected to the second instrument 6 via the distal slider 42, achieving a stable connection between the two. This arrangement saves space within the main body 1 and facilitates the convenient and stable connection and control of the second instrument 6.

[0090] The connection portion in the present application only needs to be a structure that passes through the through hole 21 or the through groove to connect the second slider 4 and the second device 6 .

[0091] Please refer to Figure 8 In the above embodiment, the connection portion passing through the through hole 21 or the through slot may be a second operating wire 6a directly connecting the second slider 4 and the second instrument 6, and the second operating wire 6a is provided through the through hole or the through slot;

[0092] Alternatively, please refer to Figures 1 to 5 The connecting portion may also be specifically the rod 41 . When the second slider 4 is connected to the rod 41 and the other end of the rod 41 is connected to the distal slider 42 , the second operating wire 6 a is preferably connected to the distal slider 42 .

[0093] In order to further control the structural dimensions inside the main body 1, based on the above embodiment, the first slider 3 is provided with a first through hole 31 or a first sliding groove, and the rod 41 can slide through the first through hole 31 or the first sliding groove;

[0094] The distal slider 42 is provided with a second through hole 43 or a second sliding groove, and the connecting portion between the first slider 3 and the first instrument 5 can slide through the second through hole 43 or the second sliding groove.

[0095] The connection portion may specifically be an operating wire, wherein the first operating wire 5 a connects the first slider 3 and the first instrument 5 , and / or the second operating wire 6 a connects the second slider 4 and the second instrument 6 .

[0096] The first through hole 31 or the first chute is arranged axially, and the rod 41 can pass through the through hole 21 and the first through hole 31 in sequence and then connect to the distal slider 42. The rod 41 is arranged in conjunction with the first through hole 31 (or the first chute), and can also enhance the relative sliding guiding effect of the two.

[0097] When the through hole 21 (or through groove), the first through hole 31 (or first slide groove) and the second through hole 43 (or second slide groove) are set at the same time, the movement of the handle slider 2 can drive the first slider 3 and the second slider 4 to move in an accurate direction, thereby making the telescopic control of the corresponding instrument more precise.

[0098] Of course, several slideways can also be set inside the main body 1, which are used for the coordinated sliding of the handle slider 2, the first slider 3 and the second slider 4, and can also achieve the guiding and limiting function. In comparison, the above-mentioned several through holes can save more internal dimensions.

[0099] Based on any of the above embodiments, the elastic member 7 is a spring and is sleeved on the outside of the rod 41 . Both ends of the elastic member 7 can be connected to or abut against the first slider 3 and the distal slider 42 respectively.

[0100] Optionally, the elastic member 7 may also be other types of elastic structures.

[0101] Based on any of the above embodiments, the width between the proximal end and the distal end of the handle slider 2 is equal to the distance between the first limiting surface 11 and the second limiting surface 12. When the handle slider 2 is located in the middle position in the axial direction, the two sides of the width of the handle slider 2 contact the first slider 3 and the second slider 4 respectively.

[0102] When the handle slider 2 starts to move in any direction, it will drive the movement of the corresponding slider, thereby realizing the movement of the device to the working position and maximizing the working efficiency of the handle slider 2.

[0103] In another embodiment, the width between the proximal end and the distal end of the handle slider 2 is smaller than the distance between the first limiting surface 11 and the second limiting surface 12, so that when the handle slider 2 is located in the middle position in the axial direction, the distal side and the proximal side of the handle slider 2 are respectively at a distance from the first slider 3 and the second slider 4.

[0104] In this embodiment, before pushing the handle slider 2 to start moving in the distal or proximal direction, there will be an interval in the handle where the instrument is not operated, and the corresponding slider will start moving with a relative delay, thereby avoiding misoperation of the handle slider 2 that may cause instrument switching.

[0105] Optionally, an elastic structure is provided on the handle slider 2 so that when the handle slider 2 is not operated, it fits with one of the first slider 3 and the second slider 4, and there is a gap with the other one; or an elastic structure is provided so that when the handle slider 2 is not operated, it maintains a certain gap with both the first slider 3 and the second slider 4.

[0106] In any of the above embodiments, the first device 5 may be a first electrode.

[0107] In any of the above embodiments, the second instrument 6 may be a second electrode or a sheath.

[0108] In addition, the therapeutic device may further comprise an axially fixed third instrument 10, which may be a third electrode.

[0109] For example, the first instrument 5 can be a first electrode having a rod-shaped or needle-shaped structure (I-type knife), which can be extended to the distal end under the push of the first slider 3 to perform operations such as marking and cutting; the second instrument 6 can be a sheath, which moves toward the proximal end under the push of the second slider 4, and retracts to the proximal end so that the third instrument 10 located at the distal end is exposed at the distal end of the sheath, so that the third instrument 10 can start working; the third instrument 10 can be an enlarged second electrode passed through by the first electrode (O-type knife), which can perform operations such as hemostasis and cutting when exposed from the sheath.

[0110] The first electrode and then the third electrode may also be electrodes of other shapes to form different multifunctional electric knives. The structural relationship between the two is not limited to being through-set, but may also be arranged in parallel.

[0111] Please refer to Figure 9 、 Figure 10 and Figure 11 ,in, Figure 9 is a cross-sectional view of the distal position in the initial state; Figure 10 is a cross-sectional view of the distal end of the first instrument in a working state; Figure 11 This is a cross-sectional view of the distal end of the second instrument in its working state.

[0112] Take the example where the first instrument 5 is a first electrode and the second instrument 6 is a sheath.

[0113] Please refer to Figure 9 , when in the initial state, the handle slider 2 is located in the middle, and the first instrument 5 and the second instrument 6 are both in the non-working position;

[0114] Please refer to Figure 10 , the handle slider 2 pushes the first electrode distally to push it out of the sheath, and the second instrument 6 remains in its original position;

[0115] Please refer to Figure 11The handle slider 2 moves toward the proximal end to reset the first electrode, and the handle slider 2 continues to move to push the sheath toward the proximal end, causing the sheath to retract so as to expose the third instrument 10.

[0116] In the initial state, the third electrode can be positioned further distally than the first electrode; the extended length of the first electrode can also be longer than the retracted length of the sheath. This ensures that when the sheath is retracted, the third electrode is exposed while the first electrode is not, allowing the operator to safely perform surgery using the third electrode alone. These telescopic length settings can be achieved by providing different sliding spaces (lengths) for the slider at the handle end, allowing for adaptive design based on actual needs.

[0117] Of course, the above instruments can also be combined in other ways to achieve different surgical operations, and are not limited to instruments such as electrodes. For example, the second instrument 6 can be a hook for pulling a wire, etc., to achieve surgical operations such as suturing. The above descriptions of the above situations are only for example and are not intended to limit the implementation of the present invention.

[0118] In a specific embodiment, the main body 1 and the handle slider 2 are respectively provided with elastic protrusions 8 and grooves 9 for engaging with each other. When the handle slider 2 slides, the elastic protrusions 8 can slide into or out of the grooves 9. The number and arrangement positions of the elastic protrusions 8 and grooves 9 satisfy the following requirements:

[0119] When the handle slider 2 is moved to make the first instrument 5 located at the first instrument working position, the elastic protrusion 8 is engaged with the groove 9;

[0120] And / or, when the handle slider 2 moves to the point where the second instrument 6 is located at the second instrument working position, the elastic protrusion 8 is engaged with the groove 9 .

[0121] The engaging relationship between the elastic protrusion 8 and the groove 9 can be used to position the handle slider so that it stops when the first instrument 5 is in the first instrument working position or the second instrument 6 is in the second instrument working position. When the handle slider 2 moves to the first instrument 5 in the first instrument working position, the elastic protrusion 8 engages with the corresponding groove 9; when the second instrument 6 is in the second instrument working position, the elastic protrusion 8 engages with the other corresponding groove 9.

[0122] The above-mentioned elastic protrusion 8 and groove 9 can also be used to provide the operator with a sense of jamming. When the two are engaged, push the handle slider 2 in the opposite direction, and the elastic protrusion 8 disengages from the groove 9. At this time, the external force acting on the handle slider 2 is cancelled, and the handle slider 2 is only affected by the elastic part 7 and will return to its initial position, and the first slider 3 and the second slider 4 also return to their initial positions, the first slider 3 contacts the first limit surface 11, and the second slider 4 contacts the second limit surface 12.

[0123] In this embodiment, the elastic protrusion 8 and groove 9 cooperate to temporarily position the handle slider 2, providing the operator with a sense of frustration to indicate the current position, enabling precise control of the instrument's switching movement. If the operating force on the handle slider 2 is released at this time, even a small amount of force will not cause the electrode to move out of the working position. After the clamping is released by external force, the elastic member 7 can drive the handle slider 2 to return to its original position, enabling convenient and quick operation.

[0124] Based on the above examples, please refer to Figure 8 In one embodiment, elastic protrusions 8 are provided at the proximal and distal ends of the handle slider 2, and at least two grooves 9 are provided axially on the main body 1, which are used to engage with the corresponding elastic protrusions 8 in the first instrument working state and the second instrument working state, respectively.

[0125] Optionally, the position of the groove 8 at the distal end of the main body 1 can correspond to the first instrument working position, and the position of the groove 8 at the proximal end of the main body 1 can correspond to the second instrument working position, thereby achieving accurate prompting. Of course, it can also correspond to the extreme position of the handle slider 2 to avoid damage to the instrument caused by movement beyond the extreme position.

[0126] Optionally, a thumb operation hole is provided at the tail of the main body 1 , and the handle slider 2 is provided with two matching operation holes, which are symmetrically arranged about the center line of the main body 1 .
