Description

Technical Field

[0001] The present application relates to a therapeutic device, and more particularly, to a manipulation handle, a therapeutic device having a manipulation handle, and therapeutic equipment. Background Art

[0002] Minimally invasive technology is the development trend of modern surgery, but it will still leave scars on the patient's body surface. Therefore, scarless surgery came into being. In order to leave no scars on the body surface, the surgery must be completed by a flexible endoscope through the natural cavity. Therefore, flexible endoscopic surgery through the natural cavity has become a research hotspot for scarless surgery and is also the third-generation surgical procedure after open surgery and laparoscopic surgery. Scarless surgery on the body surface has less physical trauma, less psychological trauma, and a corresponding reduction in intraoperative and postoperative complications. In addition, natural orifice endoscopic surgery does not require general anesthesia, uses less anesthetic drugs, reduces the depth of anesthesia, and some patients are awake, which greatly reduces the risk of anesthesia. Postoperative recovery is faster, the recovery time is significantly shortened, and the occurrence of postoperative complications is reduced. It is more beneficial for extremely frail patients and patients with higher surgical risks.

[0003] The Overstitch stapler (https: / / apolloendo.com / physicians / physicians-overstitch / overstitch / ) and the recently launched Endoscopic HeliX Tacking System (https: / / www.x-tack.com / ) from Apollo Endoscopy (USA) partially address the problem of closure of internal tissues through natural cavities. While the latter can suture larger wounds or other targeted tissues, it not only has numerous accessories and is more complex to operate, but also relies on at least three metal spiral staples for suturing, and again, clips for knotting. The sharp, hard staples, which are rotated through tissue for suturing, remain in the body, making it difficult to rule out secondary damage to the digestive system, including perforation, intestinal leakage, adhesions, and even the urinary and reproductive systems. Furthermore, when combined with the hard clips used for knotting, digestive tract peristalsis and abdominal movements make it even more difficult to avoid injury. Furthermore, both external manipulation devices have numerous parts, complex assembly, and inconvenient operation. They can only be fixed in one direction and at a single location, requiring an assistant to operate them with both hands.

[0004] Chinese invention patent application 202310000329.7 (filing date January 3, 2023) discloses a stapler, a therapeutic device having a stapler, and a therapeutic device. The patent realizes the suturing and knotting of soft tissue in the body by controlling the needle insertion assembly and the anti-retraction needle assembly. However, in this application, the control handle has a complex structure and cumbersome assembly, resulting in high production costs. In addition, the direction of the control handle is fixed when connected to the endoscope, and the operator needs to adjust the position of the hand to adapt to the operation direction, which makes the operation inconvenient.

[0065] This embodiment provides a stapler, a control handle that cooperates with the stapler, a treatment device consisting of the stapler and the control handle, and a treatment system consisting of the treatment device and an endoscope that cooperates with the stapler. The stapler provided in this embodiment can be used not only with an endoscope, but also with other devices that can achieve steering guidance.

[0066] Example 1

[0067] like Figures 1 to 24 As shown, the suturing device 1 provided in this embodiment is used to enter the body through a natural cavity or other passage to close (suture) body tissues in order to perform a surgical operation in the body. The suturing device 1 includes a main housing 11, a suturing needle 13 and a needle insertion assembly 12. The main housing 11 is used to be connected to the tip of an endoscope, and the main housing 11 is used to install the suturing needle 13 and the needle insertion assembly 12. The suturing needle 13 is slidably arranged on the main housing 11. The needle insertion assembly 12 is arranged on the main housing 11 and forms a separable engaging relationship with the suturing needle 13 to control the advancement of the suturing needle 13. Specifically, the needle insertion assembly 12 includes a driving member and a clamping member 122. The clamping member 122 is used to be in a separable engaging relationship with the suturing needle 13. The driving member is used to act on the engaged clamping member 122 and the suturing needle 13, so that the clamping member 122 drives the suturing needle 13 forward. When the needle is inserted next time, the driving member and the engaging member 122 are reset, and the driving member acts on the engaged engaging member 122 and the suture needle 13 again, so that the engaging member 122 drives the suture needle 13 forward, and the cycle is repeated to achieve continuous suturing.

[0068] In some examples, the main housing 11 includes a first housing 111 and a second housing 112. The first housing 111 is used to connect to the endoscope. The second housing 112 is connected to the first housing 111 and is used to install the suture needle 13 and the needle insertion assembly 12.

[0069] In some examples, the first housing 111 has a connecting handle 1111 extending along its axial direction, and the first housing 111 is connected to the second housing 112 via the connecting handle 1111. In a specific configuration, the connecting handle 1111 is provided with a connecting groove, and the second housing 112 may be provided with a connecting protrusion. The shape and size of the connecting protrusion match the shape and size of the connecting groove, and the connecting protrusion can be inserted into the connecting groove to connect the connecting handle 1111 and the second housing 112. However, this embodiment is not limited to this.

[0070] In some examples, in order to firmly connect the first shell 111 and the second shell 112, the connection seam formed by connecting the connection groove and the connection protrusion can be welded together by laser welding. However, this embodiment does not impose any restrictions on this. In other embodiments, the main shell 11 may not be divided into two parts, the first shell 111 and the second shell 112, that is, the main shell 11 can be formed by integral molding. The integrally formed main shell 11 makes the connection between the first shell 111 and the second shell 112 have a smooth transition and no sharp corners, thereby greatly reducing the damage caused by the stapler 1 touching the tissue in the body.

[0071] In some examples, the outer surfaces of the first housing 111 and the second housing 112 are both smooth and have no sharp edges. This configuration minimizes the impact of the endoscope's field of view on the stapler 1, facilitates in-vivo suturing operations, and reduces damage to in-vivo tissues caused by contact. Furthermore, the curved outer surface also prevents damage to in-vivo tissues caused by the edges of the housing during operation. However, this embodiment does not impose any limitations on this.

[0072] In some examples, the first housing 111 has a channel in the middle thereof, and when used in conjunction with an endoscope, the channel enables the stapler 1 to be sleeved on the front end of the endoscope. However, this embodiment does not impose any limitation on this.

[0073] like Figure 4As shown, in some examples, a first slide groove 1121 and a second slide groove 1122 are provided in the second shell 112. In this embodiment, the second shell 112 is an arc-shaped structure, and the first slide groove 1121 and the second slide groove 1122 are both arranged along the arc direction of the second shell 112. In the specific setting, the suture needle 13 is arranged in the first slide groove 1121, and the engaging member 122 is arranged in the second slide groove 1122. In order to enable the engaging member 122 to engage with the suture needle 13, a first slit can be provided between the first slide groove 1121 and the second slide groove 1122, so that the engaging member 122 can pass through the first slit and enter the first slide groove 1121. In order to enable the engaging member 122 to be connected to the driving member, a second slit 1125 can be provided between the second slide groove 1122 and the outside world, so that the driving member can pass through the second slit 1125 and enter the first slide groove 1121, as shown in FIG. Figures 1 to 3 However, this embodiment does not impose any limitation on this.

[0074] In some examples, the first and second chute grooves 1121, 1122 are arranged in an overlapping manner along the axial direction of the second housing 112. However, this embodiment is not limited to this. In other embodiments, the first and second chute grooves 1121, 1122 may be arranged in sequence along the radial direction of the second housing 112. In other words, one of the first and second chute grooves 1121, 1122 is located outside the other. This arrangement can reduce the height of the second housing 112, thereby expanding the field of view of the endoscope.

[0075] like Figure 18 and Figure 20 As shown, in some examples, the second housing 112 is provided with a first reverse bevel 1126 and a second reverse bevel 1127. Specifically, the first reverse bevel 1126 and the second reverse bevel 1127 are located on either side of the middle portion of the second chute 1122. Specifically, the first reverse bevel 1126 is provided on the sidewalls of the first slit, and the second reverse bevel 1127 is provided on the inner wall of the second chute 1122. During use, the first reverse bevel 1126 can prevent the engaging member 122 from retracting when driving the suture needle 13 forward, and the second reverse bevel 1127 can prevent the engaging member 122 from retracting when resetting. However, this embodiment does not impose any limitation on this.

[0076] like Figure 4 、 Figure 6 and Figure 7 As shown, in some examples, in order to achieve the engagement of the suture needle 13 with the engaging member 122 , the suture needle 13 may be provided with an engaging portion 131 , so as to utilize the engaging portion 131 to engage with the engaging member 122 .

[0077] In some examples, the engaging portion 131 can be formed by a depression provided on the surface of the suture needle 13, that is, the surface of the suture needle 13 is provided with a groove, and the side of the groove close to the tip of the suture needle 13 forms the engaging portion 131. However, this embodiment does not impose any limitation on this. In other embodiments, the engaging portion 131 can also be formed by a protrusion provided on the surface of the suture needle 13, or by a through hole penetrating the suture needle 13.

[0078] In some examples, the depth of the groove is no greater than one-quarter of the diameter of the suture needle 13. This arrangement can prevent the groove from being too deep, which may reduce the strength of the suture needle 13 and thus cause the suture needle 13 to break. However, this embodiment does not impose any limitation on this.

[0079] In some examples, there are multiple engaging portions 131 , which are spaced apart along the axial direction of the suturing needle 13 . In specific use, the engaging member 122 can engage with any one or more of the multiple engaging portions 131 .

[0080] like Figure 7 As shown, in some examples, the engaging portion 131 can be tilted as a whole toward the tail of the suture needle 13. In this way, barbs can be formed on the surface of the suture needle 13 to limit the retreat of the suture needle 13 during suturing. Compared with the arrangement of an anti-retraction needle assembly between the suture needle 13 and the main housing 11, this anti-retraction design can reduce the number of parts of the suture device 1, which is beneficial for saving costs, improving assembly efficiency, and reducing risk links. In addition, as the number of parts is reduced, the resistance during the movement of the suture needle 13 will also be reduced, thereby facilitating the operation of the operator. However, this embodiment does not impose any limitation on this.

[0081] like Figure 7 As shown, in some examples, the engaging portions 131 are provided on opposite sides of the suture needle 13. This arrangement can enhance the anti-retraction effect of the suture needle 13. Moreover, when the two sides of the suture needle 13 are respectively engaged with the engaging members 122, the force applied to the suture needle 13 is more evenly distributed, making the suture needle 13 move more smoothly. However, this embodiment is not limited to this. In other embodiments, the engaging portion 131 can be provided on one side of the suture needle 13 or on the central axis of the suture needle 13.

[0082] In some examples, when the engaging portion 131 is formed by a depression provided on the surface of the suture needle 13, the engaging portions 131 on both sides of the suture needle 13 are staggered. This arrangement can prevent the suture needle 13 from being partially undersized, which helps to ensure the strength of the suture needle 13. However, this embodiment does not impose any limitation on this.

[0083] In some examples, the engaging member 122 can change its posture to engage or disengage with the suture needle 13. For example, the engaging member 122 has a first posture and a second posture. In the first posture, the engaging member 122 is engaged with the suture needle 13, and in the second posture, the engaging member 122 is disengaged from the suture needle 13. However, this embodiment is not limited to this.

[0084] like Figures 4 and 5 As shown, in some examples, the engaging member 122 includes a slider 1221 and a spring claw 1222. The spring claw 1222 is elastic and is provided on the slider 1221. The slider 1221 is slidably and rotatably provided on the main housing 11 (second slide groove 1122), and has a first posture and a second posture relative to the main housing 11. In the first posture, the spring claw 1222 and the suture needle 13 are engaged. In the second posture, the spring claw 1222 and the suture needle 13 are disengaged. With this arrangement, the engaging member 122 can be engaged or disengaged with the suture needle 13 by rotating the slider 1221. Compared with the method of controlling the extension and retraction of the needle teeth to engage in the prior art, this method not only can ensure stable engagement, but also can simplify the structure of the engaging member 122, which is conducive to reducing production costs, improving production efficiency, and reducing risk points during use. In addition, since the engagement or disengagement of the engaging member 122 and the suturing needle 13 is achieved by rotating the slider 1221, the push-back force generated by the engaging member 122 and the suturing needle 13 when disengaging can be reduced, thereby preventing the engaging member 122 from causing the suturing needle 13 to retreat when resetting. However, this embodiment does not impose any limitation on this.

[0085] In some examples, the slider 1221 rotates in different directions relative to the main housing 11 to perform posture conversion. In a specific setting, the slider 1221 rotates in a first direction relative to the main housing 11 to a first posture, and the slider 1221 rotates in a second direction relative to the main housing 11 to a second posture, and the first direction and the second direction are opposite directions. For example, the first direction can be Figure 12 The second direction can be the clockwise direction of the slider 1221 shown. Figure 9 The slider 1221 is shown in the counterclockwise direction. However, this embodiment does not impose any limitation on this.

[0086] like Figure 23-24As shown, in some examples, the slider 1221 cooperates with the first transverse rib 1123 provided on the main housing 11, so that the slider 1221 can rotate relative to the main housing 11 to the first posture along the first direction. In a specific setting, the first transverse rib 1123 can be a ridge protruding from the inner surface of the second slide groove 1122, which is located at the first end of the second housing 112. When the engaging member 122 is reset (moved toward the left end of the second slide groove), the first transverse rib 1123 can partially limit the slider 1221 (such as the upper protrusion of the slider 1221) so that the slider 1221 can rotate relative to the main housing 11 to the first posture along the first direction. However, this embodiment does not impose any limitation on this.

[0087] like Figure 21-22 As shown, in some examples, the slider 1221 cooperates with the second transverse rib 1124 provided on the main housing 11, so that the slider 1221 can rotate relative to the main housing 11 to the second posture along the second direction. In a specific setting, the second transverse rib 1124 can be a ridge protruding from the inner surface of the second slide 1122, which is located at the second end of the second housing 112. When the engaging member 122 drives the suture needle 13 forward, the second transverse rib 1124 can partially limit the slider 1221 (such as the upper protrusion of the slider 1221) so that the slider 1221 can rotate relative to the main housing 11 to the second posture along the second direction. However, this embodiment does not impose any limitation on this.

[0088] In some examples, the slider 1221 may be a spherical structure or a cylindrical structure. However, this embodiment does not impose any limitation on this. In this embodiment, it is preferred that the slider 1221 is a spherical structure.

[0089] In some examples, the claw 1222 can cooperate with a limiting portion provided on the main housing 11 to limit the slider 1221 from rotating in the first direction relative to the main housing 11 when resetting. In a specific configuration, the limiting portion can be a claw groove 1128 that cooperates with the claw 1222. Specifically, the claw groove 1128 is provided on the inner surface of the second slide groove 1122 and is provided along the arc direction of the second housing 112, such as Figure 12As shown. In the first posture, the spring claw 1222 and the suture needle 13 engage and disengage the claw groove 1128, thereby releasing the engagement with the claw groove 1128. In the second posture, the spring claw 1222 and the suture needle 13 disengage and engage the claw groove 1128, thereby achieving engagement with the claw groove 1128. When the spring claw 1222 engages with the claw groove 1128, the claw groove 1128 can limit the spring claw 1222, preventing the spring claw 1222 from withdrawing from the claw groove 1128 unless subjected to external force, thereby preventing the slider 1221 from rotating in the first direction relative to the main housing 11. This arrangement can prevent the slider 1221 from rotating relative to the second housing 112 during reset, thereby preventing the engaging member 122 from returning to the first posture prematurely and affecting the reset of the engaging member 122. However, this embodiment does not impose any limitation on this.

[0090] like Figure 4 As shown, in some examples, the spring claw 1222 may include a first spring claw 1222a and a second spring claw 1222b, and the first spring claw 1222a and the second spring claw 1222b respectively cooperate with different engaging portions 131 provided on the suture needle 13 to engage the engaging member 122 with the suture needle 13. In a specific configuration, the first spring claw 1222a and the second spring claw 1222b respectively cooperate with the engaging portions 131 provided on both sides of the suture needle 13 to engage the engaging member 122 with the suture needle 13. However, this embodiment is not limited to this.

[0091] like Figure 4 As shown, in some examples, there may be multiple first spring claws 1222a and multiple second spring claws 1222b. In a specific configuration, the multiple first spring claws 1222a may engage with the multiple engaging portions 131 located on the outside of the suture needle 13, and the multiple second spring claws 1222b may engage with the multiple engaging portions 131 located on the inside of the suture needle 13. This configuration helps disperse stress and improve the stability of the suture needle 13. However, this embodiment is not limited to this.

[0092] In some examples, the driving member can be a silk thread. In this embodiment, the silk thread is defined as an operating rope 121. In a specific implementation, the first end of the operating rope 121 (passing through the second slit 1125) is connected to the engaging member 122, and the second end of the operating rope 121 is led out through the clamp channel tube of the endoscope or an external pipe attached to the outside of the endoscope. During use, the operator can apply tension to the second end of the operating rope 121 through human or mechanical power to tighten the operating rope 121 and drive the engaging member 122 to move in the second slide groove 1122 along the needle insertion direction, thereby achieving the insertion of the suture needle 13. However, this embodiment does not impose any limitation on this. In other embodiments, the driving member may not adopt the operating rope 121, and control of the suture needle 13 may be achieved through other structures.

[0093] like Figures 1 to 4 As shown, in some examples, a transmission mechanism 123 can be disposed between the driving member and the engaging member 122. At least a portion of the transmission mechanism 123 is exposed outside the main housing 11 and connected between the driving member and the engaging member 122. Furthermore, under the action of the driving member, the transmission mechanism 123 can drive the engaging member 122 to reciprocate along the advancing direction of the suture needle 13. Compared to a method in which the operating cord 121 is directly connected to the engaging member 122, this embodiment connects the driving member and the engaging member 122 via the transmission mechanism 123. The transmission mechanism 123 can be used to transmit power from the driving member to the engaging member 122, causing the engaging member 122 to reciprocate along the advancing direction of the suture needle 13, thereby driving the suture needle 13 forward. Furthermore, since at least a portion of the transmission mechanism 123 is exposed outside the main housing 11, that is, part or all of the transmission mechanism 123 can be disposed on the outer surface of the main housing 11. This arrangement can shorten the length of the operating rope 121 exposed in the body and reduce the turning points of the operating rope, thereby reducing the interference of other operating instruments and body tissues on the operating rope 121, which is beneficial to reducing the resistance of the operating rope 121 and reducing the risk of entanglement of the operating rope 121.

[0094] In some examples, the transmission mechanism 123 may be a universal joint transmission mechanism 123. However, this embodiment does not impose any limitation on this.

[0095] like Figures 1 to 4 As shown, in some examples, the transmission mechanism 123 may include at least one transmission shaft 1231, a movable member, and a reset member. The first end of the at least one transmission shaft 1231 is universally connected to the engaging member 122, and the second end of the at least one transmission shaft 1231 is universally connected to the movable member. The movable member is disposed within the main housing 11 and connected to a driving member. Under the action of the driving member, the movable member can move relative to the main housing 11 to change the position of the first end of the at least one transmission shaft 1231. The reset member is disposed within the movable member and can be used to reset the movable member when the action of the driving member is lost. Specifically, the driving member can act on the movable member, and the movable member can move under the action of the driving member, thereby driving the engaging member 122 to reciprocate along the forward direction of the suture needle 13 via the at least one transmission shaft 1231. This arrangement enables transmission of the transmission mechanism 123. However, this embodiment does not impose any limitations on this.

[0096] like Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 15 and Figure 16As shown, in some examples, at least one transmission shaft 1231 may include a first transmission shaft 1231a and a second transmission shaft 1231b, wherein the first end of the first transmission shaft 1231a is connected to the engaging member 122, the second end of the first transmission shaft 1231a is connected to the first end of the second transmission shaft 1231b, and the second end of the second transmission shaft 1231b is connected to the movable member via a spherical hinge. In a specific configuration, the angle between the second transmission shaft 1231b and the movable member, as well as the angle between the second transmission shaft 1231b and the first transmission shaft 1231a, may vary, thereby changing the position of the first end of the first transmission shaft 1231a. However, this embodiment does not impose any limitation on this.

[0097] In some examples, the first and second ends of the first transmission shaft 1231a and the second end of the second transmission shaft 1231b can each be provided with a ball head, and the movable end of the movable member, the first end of the second transmission shaft 1231b, and the engaging member 122 can each be provided with a ball seat. Furthermore, to reduce the structural dimensions of the second housing 112, the slider 1221 of the engaging member 122 can be designed as a ball seat, eliminating the need for a separate ball seat on the slider 1221. However, this embodiment is not limited to this.

[0098] In some examples, the first transmission shaft 1231a is located in the second slit 1125, and the length of the first transmission shaft 1231a is consistent with the wall thickness of the second slide groove 1122. This configuration allows the ball joints at both ends of the first transmission shaft 1231a to limit the first transmission shaft 1231a, preventing it from tilting relative to the second housing 112. However, this embodiment is not limited to this.

[0099] like Figures 1 to 4As shown, in some examples, the movable member includes a telescopic rod 1232, the first end of which is fixedly connected to the main housing 11 (first housing 111), and the second end of the telescopic rod 1232 is universally connected to the second end of at least one transmission shaft 1231 (the second end of the second transmission shaft 1231b). During use, the driving member is connected to the second end of the telescopic rod 1232. When the driving member is tightened, the telescopic rod 1232 contracts, and the angle between the telescopic rod 1232 and the second transmission shaft 1231b, the angle between the second transmission shaft 1231b and the first transmission shaft 1231a, and the position of the first end of the first transmission shaft 1231a change, thereby enabling the engaging member 122 to move within the second slide groove 1122. When the driving member is released, the reset member drives the telescopic rod 1232 to extend, and the angle between the telescopic rod 1232 and the second transmission shaft 1231b, the angle between the second transmission shaft 1231b and the first transmission shaft 1231a, and the position of the first end of the first transmission shaft 1231a change again, thereby enabling the engaging member 122 to continue to move or reset in the second sliding groove 1122. However, this embodiment is not limited to this.

[0100] In some examples, the engaging member 122 completes a needle insertion operation when the telescopic rod 1232 completes a single extension. For example, after the telescopic rod 1232 completes a single contraction, the engaging member 122 moves half the length of the second slide 1122. After the telescopic rod 1232 completes a single extension, the engaging member 122 moves half the length of the second slide 1122. In other words, the telescopic rod 1232 must complete a single reciprocating motion before the engaging member 122 moves from one end of the second slide 1122 to the other. However, this embodiment is not limited to this. In other embodiments, the engaging member 122 completes a single needle insertion operation when the telescopic rod 1232 completes multiple extensions or less than one extension.

[0101] like Figures 4 and 5 As shown, in some examples, the reset member can be a compression spring 1233, which is disposed in the telescopic rod 1232. During use, the compression spring 1233 is compressed when the telescopic rod 1232 contracts, and accumulates elastic potential energy. When the driving member is released, the compression spring 1233, under the action of its elastic potential energy, drives the telescopic rod 1232 to extend and reset, thereby driving the engaging member 122 to reset or continue to advance via the transmission shaft. However, this embodiment does not impose any limitations on this. In other embodiments, the reset member can be replaced by a structure made of a polymer material such as a metal spring or elastic silicone with a certain restoring force or elasticity.

[0102] In order to more clearly explain how the stapler 1 provided in the embodiment of the present application performs the suturing action of the target suture tissue, the following Figures 8-16To clearly indicate the position of internal parts, not all components are shown in the drawings. Figures 8-16 In terms of the positional relationship.

[0103] like Figure 8 As shown, in the initial position, the operating rope 121 is loose, the engaging member 122 is located on the left side of the second slide groove 1122, and the spring claw 1222 of the engaging member 122 is located in the first slide groove 1121 and engaged in the grooves on both sides of the needle tail of the suture needle 13, that is, there is a linkage relationship between the engaging member 122 and the suture needle 13.

[0104] like Figure 9 As shown, the operating rope 121 is pulled, and the operating rope 121 pulls the telescopic rod 1232 to retract it, and the second transmission shaft 1231b moves up following the telescopic rod 1232, and the angle between the first transmission shaft 1231a and the second transmission shaft 1231b and the position of the first end of the first transmission shaft 1231a change, so that the engaging member 122 moves to the right side of the second slide groove 1122, thereby driving the suture needle 13 forward. When the compression spring 1233 is compressed to the limit, the telescopic rod 1232 can no longer be compressed. At this time, the first end of the first transmission shaft 1231a and the engaging member 122 are located in the middle of the second slide groove 1122.

[0105] like Figure 10 As shown, the operating rope 121 is loosened, and the force of the operating rope 121 on the telescopic rod 1232 disappears. The compression spring 1233 provides the telescopic rod 1232 with a force to stretch it, and the telescopic rod 1232 gradually stretches. During the stretching process of the telescopic rod 1232, the first reverse inclined groove 1126 forms a limit on the spring claw 1222, preventing the engaging member 122 from moving to the left side of the second slide groove 1122, so that the engaging member 122 will continue to move to the right side of the second slide groove 1122, thereby continuing to drive the suture needle 13 forward.

[0106] like Figure 11 As shown, continue to loosen the operating rope 121, the engaging member 122 continues to drive the suture needle 13 forward, and when the engaging member 122 approaches the right side of the second chute 1122, the second transverse rib 1124 provided on the right side of the second chute 1122 will limit the engaging member 122, so that the engaging member 122 will rotate 90 degrees counterclockwise relative to the second housing 112. At the same time, the claw 1222 will bend or open outward to exit the grooves on both sides of the suture needle 13, that is, the engaging member 122 and the suture needle 13 are released. Subsequently, the compression spring 1233 returns to its initial state, and the engaging member 122 completely reaches the right side of the second chute 1122, that is, a needle insertion is completed.

[0107] like Figure 12As shown, the operating rope 121 is pulled again, and the operating rope 121 pulls the telescopic rod 1232 to retract it, and the second transmission shaft 1231b moves up with the telescopic rod 1232, and the angle between the first transmission shaft 1231a and the second transmission shaft 1231b and the position of the first end of the second transmission shaft 1231b change, so that the engaging member 122 moves to the left side of the second slide groove 1122. When the compression spring 1233 is compressed to the limit, the telescopic rod 1232 can no longer be compressed. At this time, the first end of the first transmission shaft 1231a and the engaging member 122 are located in the middle of the second slide groove 1122.

[0108] like Figure 13 As shown, the operating rope 121 is loosened again, and the force of the operating rope 121 on the telescopic rod 1232 disappears. The compression spring 1233 provides the telescopic rod 1232 with a force to stretch it, and the telescopic rod 1232 gradually stretches. During the stretching process of the telescopic rod 1232, the second reverse inclined groove 1127 limits the spring claw 1222, preventing the engaging member 122 from moving to the right side of the second sliding groove 1122, so that the engaging member 122 will continue to move to the left side of the second sliding groove 1122.

[0109] like Figure 14 As shown, continue to loosen the operating rope 121, and the engaging member 122 continues to move toward the left side of the second slide groove 1122. When the engaging member 122 approaches the left side of the second slide groove 1122, the first transverse rib 1123 provided on the left side of the second slide groove 1122 will limit the engaging member 122, so that the engaging member 122 will rotate clockwise relative to the second shell 112.

[0110] like Figure 15 As shown, the operating rope 121 is completely loosened, the compression spring 1233 returns to its initial state, and the engaging member 122 completely reaches the left side of the second slide groove 1122. At this time, the spring claw 1222 is reset to the first slide groove 1121 and engaged in the grooves on both sides of the tip of the suture needle 13, that is, the engaging member 122 and the suture needle 13 are in a linkage relationship.

[0111] like Figure 16 As shown, pulling and releasing the operating rope 121 again can move the engaging member 122 from the left side to the right side of the second sliding groove 1122, thereby restoring the suture needle 13 to the initial position, that is, completing one needle removal.

[0112] The three pulls and releases of the operating cord 121 complete a single suture with the suture needle 13. Repeating these steps allows for the suturing of the target tissue or the tying of the suture thread. However, this embodiment does not impose any restrictions on the number of pulls required for a single suture. It should be understood that in other embodiments, the number of pulls required for a single suture can be adjusted by adjusting the extension and retraction of the telescopic rod 1232 and the spacing of the grooves on the suture needle 13.

[0113] like Figures 38 to 44 As shown, in some examples, the operation of the operating rope can be accomplished by operating the operating handle 2. In other words, the operation of the driving member can be tightened or released by operating the operating handle 2. However, this embodiment is not limited to this. In other embodiments, the driving member can also be other components that can drive the engagement member to move.

[0114] like Figure 38 As shown, in some examples, the manipulation handle 2 includes a handle body 21, at least one connector 22, a pull handle 23, and a reset member 24. At least one connector 22 is provided on the handle body 21 and is used to connect the handle body 21 to the endoscope. The pull handle 23 is slidably provided on the handle body 21 and connected to the operating rope 121. The pull handle 23 has a first position and a second position that slide relative to the handle body 21, as shown in FIG. Figure 42 As shown, in the first position, the operating rope is in a tensioned state, as shown in FIG. Figure 43 As shown, in the second position, the operating rope is in a relaxed state. The reset member 24 is arranged between the handle body 21 and the wire pull handle 23, and the reset member 24 is used to keep the wire pull handle 23 in the second position when it is not subjected to external force. That is to say, when the wire pull handle 23 slides from the second position to the first position, the operating rope is gradually tightened. When the wire pull handle 23 reaches the first position, the operating rope 121 is in a tightened state. On the contrary, when the wire pull handle 23 slides from the first position to the second position, the operating rope 121 is gradually loosened. When the wire pull handle 23 reaches the second position, the operating rope is in a relaxed state. With this arrangement, the tightening and releasing of the operating rope 121 can be achieved by controlling the wire pull handle 23 to slide relative to the handle body 21. Compared with the method of using a pulley and a clutch disk to reel in the operating rope 121 in the prior art, the structure of the control handle 2 can be greatly simplified, thereby simplifying the assembly process and reducing production costs. However, this embodiment does not impose any restrictions on this.

[0115] like Figure 38 、 Figure 40 and Figure 41 As shown, in some examples, the handle body 21 is provided with a guide rod 211, and the wire pull handle 23 is sleeved on the guide rod 211 and can slide axially along the guide rod 211. During use, while the wire pull handle 23 slides axially along the guide rod 211, the guide rod 211 can also guide the wire pull handle 23, which helps to improve the stability of the wire pull handle 23 and facilitates operation by the operator. However, this embodiment does not impose any limitation on this.

[0116] like Figure 40As shown, in some examples, the handle body 21 is provided with an assembly groove 212, and the guide rod 211 is disposed in the assembly groove 212. In a specific configuration, the guide rod 211 is disposed through the handle body 21, and a portion of the guide rod 211 is located in the assembly groove 212. Compared to disposing the guide rod 211 on the outer surface of the handle body 21, this configuration can simplify the external structure of the control handle 2, facilitate reducing the structural dimensions of the control handle 2, and make it easier to pack and carry. However, this embodiment does not impose any limitation on this.

[0117] like Figure 38 to Figure 13 In some examples, the handle body 21 may be provided with a guide slot 2111 so that the operating cord can pass through the guide slot 2111 and then be connected to the pull handle 23. During use, the guide slot 2111 can guide the operating cord to prevent it from getting tangled. However, this embodiment does not impose any limitation on this.

[0118] In some examples, a guide slot 2111 is formed at the end of the guide rod 211. Specifically, one end of the guide rod 211 extends through the handle body 21, while the other end is located outside the handle body 21. The guide slot 2111 is formed at the end of the guide rod 211 located outside the handle body 21. This arrangement eliminates the need for grooves on the surface of the handle body 21, simplifies the manufacturing process, and improves production efficiency. However, this embodiment is not limited to this.

[0119] In some examples, at least one connector 22 includes a first connector 221 and a second connector 222. The first connector 221 is provided on the handle body 21 and is used to connect to the operating end of the endoscope. The second connector 222 is provided on the handle body 21 and is used to connect to the forceps opening of the endoscope. During use, the control handle 2 can first be connected to the forceps opening of the endoscope through the second connector 222, and then connected to the operating end of the endoscope through the first connector 221. This arrangement can improve the connection strength between the control handle 2 and the endoscope, and prevent the control handle 2 from moving on the endoscope or falling off the endoscope during use. However, this embodiment does not impose any limitation on this.

[0120] In some examples, the first connecting member 221 is a clip, and the second connecting member 222 is a fixing nut. During use, the control handle 2 can be mounted on the operating end of the endoscope via the clip, and can be threadedly connected to the endoscope's forceps opening via the fixing nut. However, this embodiment does not impose any limitations on this. It should be noted that the clip is made of an elastic material, has an opening, and the opening can open and close under the action of its own elastic force.

[0121] like Figure 39As shown, in some examples, the first connecting member 221 and the second connecting member 222 are provided at opposite ends of the handle body 21. For example, the first connecting member 221 and the second connecting member 222 can be provided at opposite ends of the length direction of the handle body 21. However, this embodiment does not impose any limitation on this.

[0122] like Figures 38 to 41 As shown, in some examples, the first connecting member 221 is arranged on the handle body 21 through a first spherical hinge 25, and the second connecting member 222 is connected to the handle body 21 through a second spherical hinge 26. In a specific setting, the first spherical hinge 25 includes a first ball head 251 and a first ball seat 252, the first ball head 251 is arranged on the handle body 21, and the first ball seat 252 is arranged on the first connecting member 221. The second spherical hinge 26 includes a second ball head 261 and a second ball seat 262, the second ball head 261 is arranged on the second connecting member 222, and the second ball seat 262 is arranged on the handle body 21. This setting allows the first connecting member 221 and the second connecting member 222 to be rotated relative to the handle body 21 to adjust the connection direction of the first connecting member 221 and the second connecting member 222. Therefore, the control handle 2 can adjust the direction of the pull wire handle 23 when connected to the endoscope, so as to adapt to the operator's hand posture and facilitate the operator's operation. For example, Figure 43 and Figure 44 As shown, the second connecting member 222 is connected to the handle body 21 before and after rotation. However, this embodiment does not impose any limitation on this. In other embodiments, the first connecting member 221 is provided to the handle body 21 via a first rotating shaft mechanism, and the second connecting member 222 is provided to the handle body 21 via a second rotating shaft mechanism. It should be understood that the first rotating shaft mechanism and the second rotating shaft mechanism have the same structure, both including a rotating shaft and a sleeve mounted on the rotating shaft.

[0123] In some examples, the opening directions of the ball sockets of the first spherical hinge 25 and the second spherical hinge 26 are inconsistent with each other. For example, the opening direction of the ball socket of the first spherical hinge 25 is set to the right, and the opening direction of the ball socket of the second spherical hinge 26 is set to the bottom, as shown in FIG. Figure 38 This arrangement can avoid the first spherical hinge 25 and the second spherical hinge 26 from being disconnected at the same time, thereby ensuring the connection effect between the control handle 2 and the endoscope.

[0124] This embodiment does not impose any restrictions on the specific structure of the control handle 2. As long as the control handle 2 can achieve the functions of this embodiment, it can be used with the suture device provided in this embodiment. In other embodiments, the suture device can also be used independently without the control handle 2. The suture device can have a pull ring disposed at the end of the drawstring, and the drawstring is pulled by pulling the pull ring.

[0125] In another aspect, this embodiment further provides a treatment device comprising the aforementioned stapler and a control handle 2, the treatment device being used in conjunction with an endoscope. The stapler is secured to the distal end of the endoscope. The control handle 2 is secured to the operating end of the endoscope and is connected to a drive member of the stapler. The control handle 2 controls the drive member to control the advancement of the suturing needle.

[0126] In this embodiment, the treatment device may also include a hook forceps. The hook forceps are located at the distal end of the endoscope to perform a tissue clamping action or a suture hooking and pulling action, and can finally clamp the two ends of the suture to complete the suture knotting action. The hook forceps can be inserted through the endoscope's own clamp channel or through an external clamp channel, without any limitation. In actual use, two hook forceps can be inserted simultaneously through two clamp channels to perform the operation, or only one hook forceps can be used for the operation. In this embodiment, the distal end of the hook forceps is in the shape of a forceps with a hook.

[0127] On the other hand, this embodiment further provides a treatment device, comprising the above-mentioned treatment device and an endoscope. The treatment device is used in conjunction with the endoscope, and the treatment device comprises the above-mentioned suturing device and a control handle 2.

[0128] Example 2

[0129] This embodiment is basically the same as the first embodiment and its variations, with the difference being that the structure of the movable parts of the transmission mechanism 123 ′ is different.

[0130] like Figures 25 to 37 As shown, in some examples, the movable member includes a rotating shaft 1232' and a reel 1233'. The rotating shaft 1232' is disposed on the main housing 11'. The reel 1233' is sleeved on the rotating shaft 1232' and can rotate circumferentially relative to the rotating shaft 1232'. The outer edge of the reel 1233' is universally connected to the second end of at least one transmission shaft 1231' (the second end of the second transmission shaft 1231b'). During use, the driving member is wound around the outer edge of the reel 1233'. When the driving member is tightened, the reel 1233' rotates clockwise or counterclockwise relative to the rotating shaft 1232', and the angle between the first transmission shaft 1231a' and the second transmission shaft 1231b', the angle between the second transmission shaft 1231b' and the reel 1233', and the position of the first end of the first transmission shaft 1231a' change, thereby enabling the engaging member 122' to reciprocate in the second slide 1122'. However, this embodiment does not impose any limitation on this.

[0131] In some examples, the engaging member 122' completes one needle insertion operation each time the reel 1233' rotates one circle (360°). For example, after the reel 1233' rotates 180° clockwise or counterclockwise, the moving distance of the engaging member 122' is half of the second slide 1122'. After the reel 1233' continues to rotate 180° in the same direction, the moving distance of the engaging member 122' is half of the second slide 1122'. In other words, the engaging member 122' can only move from one end of the second slide 1122' to the other end after the reel 1233' has not rotated one circle. However, this embodiment does not impose any limitation on this. In other embodiments, the engaging member 122' completes one needle insertion operation each time the reel 1233' rotates multiple circles or less than one circle.

[0132] like Figure 26 As shown, in some examples, an annular groove 1233a' is provided on the outer edge of the reel 1233', and the driving member is wound within the annular groove 1233a' of the reel 1233'. This arrangement can prevent the driving member from falling off the reel 1233', thereby causing the driving member to lose its driving function. However, this embodiment is not limited to this.

[0133] In some examples, the reset member can be a scroll spring 1234', which is disposed within the reel 1233' and wound around the rotating shaft 1232'. During use, the scroll spring 1234' is wound around the rotating shaft 1232' as the reel 1233' rotates circumferentially, accumulating elastic potential energy. When the driving member is released, the scroll spring 1234', under the action of its elastic potential energy, drives the reel 1233' to rotate in the opposite direction, thereby driving the engaging member 122' to reset or continue to advance via the transmission shaft. However, this embodiment is not limited to this.

[0134] Compared to the stapler of the first embodiment, the movable parts of the stapler of this embodiment are the rotating shaft 1232' and the reel 1233', which does not require a telescopic rod to provide a telescopic space, thereby reducing the size (height) of the stapler, which is beneficial for reducing the damage to the body tissue by the stapler and reducing the impact on the endoscope field of view, making the operation safer. However, this embodiment does not impose any limitation on this.

[0135] In order to more clearly explain how the stapler provided in the embodiment of the present application performs the suturing action of the target suture tissue, the following Figures 29-37 To clearly indicate the position of internal parts, not all components are shown in the drawings. Figures 29-37 In terms of the positional relationship.

[0136] like Figure 29As shown, in the initial position, the operating rope is loose, the engaging member 122' is located on the left side of the second slide groove 1122', and the spring claw of the engaging member 122' is located in the first slide groove and engaged in the grooves on both sides of the needle tail of the suture needle 13', that is, the engaging member 122' and the suture needle 13' are in a linkage relationship.

[0137] like Figure 30 As shown, the operating rope is pulled, and the operating rope pulls the reel 1233' to rotate clockwise, and the second transmission shaft 1231b' rotates along with the reel 1233', and the angle between the first transmission shaft 1231a' and the second transmission shaft 1231b' and the position of the first end of the first transmission shaft 1231a' change, so that the engaging member 122' moves to the right side of the second slide groove 1122', thereby driving the suture needle 13' forward. When the reel 1233' rotates 1 / 4 of a circle, the suture needle 13' reaches 1 / 4 of the needle insertion.

[0138] like Figure 31 As shown, continue to pull the operating rope, the operating rope pulls the reel 1233' to make it continue to rotate clockwise. When the reel 1233' rotates another 1 / 4 circle, that is, when the reel 1233' rotates a total of 2 / 4 circles, the first end of the first transmission shaft 1231a' and the engaging member 122' are located in the middle of the second slide groove 1122', and the suture needle 13' has been inserted 2 / 4.

[0139] like Figure 32 As shown, continue to pull the operating rope, the operating rope pulls the reel 1233' to make it continue to rotate clockwise. When the reel 1233' rotates another 1 / 4 circle, that is, when the reel 1233' rotates a total of 3 / 4 circles, the suture needle 13' reaches 3 / 4 of the insertion.

[0140] like Figure 33 As shown, continue to pull the operating rope, the operating rope pulls the reel 1233' to make it continue to rotate clockwise. When the reel 1233' rotates another 1 / 4 circle, that is, when the reel 1233' rotates a total of 4 / 4 circles, the first end of the first transmission shaft 1231a' and the engaging member 122' are located on the right side of the second slide groove 1122', and the suture needle 13' has been inserted 4 / 4, that is, one needle insertion is completed.
