Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an atrial appendage clamp delivery handle and an atrial appendage clamp delivery device having the same. Background Art

[0002] Atrial fibrillation is one of the most common arrhythmias in clinical practice. The consequences of stroke caused by atrial fibrillation are very serious, with a mortality rate and disability rate of 70%. For patients with valvular atrial fibrillation, 57% of atrial thrombi originate from the left atrial appendage, and for patients with non-valvular atrial fibrillation, 90% of left atrial thrombi originate from the left atrial appendage. Even after sinus rhythm is restored, the left atrial appendage contraction is suppressed, and thrombi may still form again.

[0003] Currently, the main methods used clinically to treat patients with atrial fibrillation include left atrial appendage occlusion, left atrial appendage ligation or suture surgery, and left atrial appendage clipping. Among them, left atrial appendage clipping can deliver the atrial appendage clip to the outer side of the heart in a minimally invasive way without directly entering the heart. It causes little harm to the human body and the operation is relatively easy. It is more suitable for patients with complex physical conditions.

[0004] In the prior art, an atrial appendage clamp conveyor is usually used to extend into the human body through a minimally invasive opening, and then the position is adjusted according to the patient's left atrial appendage. After adjusting to the optimal position, the atrial appendage clamp is set at the root of the left atrial appendage. Due to the beating of the heart and the complexity of the operation, the actuator is easily affected when it is outside the heart, and the state and position of the atrial appendage clamp need to be adjusted in time. The atrial appendage clamp conveyor in the prior art includes a conveyor adjustment part and an atrial appendage clamp adjustment part, both of which are integrated in the same device, and the position of the conveyor and the cooperation between the conveyor and the atrial appendage clamp are adjusted according to actual needs. The position of the atrial appendage clamp adjustment part needs to be set with a separate limiting structure, and the adjustment procedure is strictly controlled to avoid the atrial appendage clamp falling off or even damaging the internal organs due to accidental touch or special circumstances during the operation. Due to the particularity of the heart beating, the state of the atrial appendage clamp cannot always be in the optimal position. In addition to the strict control procedure, the existing atrial appendage clamp conveyor is not convenient to use, has strict requirements on the user, and is not conducive to the adjustment process of the atrial appendage clamp, resulting in the need for multiple adjustments in the operation, which seriously affects the progress of the operation.

[0052] Embodiment 1:

[0053] like Figure 1 Picture to Figure 3As shown, in the first aspect, the first embodiment of the present application provides an atrial appendage clamp delivery handle, comprising: a housing 10 and an adjustment assembly 20, the housing 10 comprises a housing body 11 and a handle 12 connected to each other, a fixed shaft 111 is arranged in the housing body 11, and the fixed shaft 111 is arranged at a position of the housing body 11 close to the handle 12; the adjustment assembly 20 comprises a driving member 21, an adjustment structure 22 and a limiting structure 23, the driving member 21 is connected to the adjustment structure 22, the adjustment structure 22 is rotatably connected to the fixed shaft 111, an end of the driving member 21 away from the adjustment structure 22 extends out of the housing body 11, the limiting structure 23 is fixedly connected to the housing body 11, the adjustment structure 22 can move relative to the limiting structure 23, and the adjustment structure 22 and the limiting structure 23 have a locked state and an unlocked state. By arranging the adjustment assembly 20 at a position of the housing body 11 close to the handle 12, the user can realize the operation of unlocking and adjusting the direction by simply pushing and pressing, thereby improving the convenience of the atrial appendage clamp delivery handle, improving the efficiency of the operation, accelerating the operation process, and reducing the operation risk. The present application effectively solves the problem in the prior art that the atrial appendage clamp delivery handle needs to be separately provided with a limiting structure for adjusting the position of the atrial appendage clamp and the adjustment procedure of the atrial appendage clamp is strictly controlled, resulting in the atrial appendage clamp delivery handle being inconvenient to use and affecting the surgical progress.

[0054] It should be noted that the fixed shaft 111 is a cylindrical shaft body, so as to facilitate the rotation of the adjustment component 20. The driving member 21 is specifically configured as a pressing end 212 and a rod 213. The pressing end is suitable for the operator to hold the handle 12 and use the thumb to press and push to achieve unlocking and rotation. Such a setting is more suitable for ergonomic design. Unlocking and adjustment can be achieved by moving the thumb, avoiding the complicated unlocking process during the operation, and having good controllability and convenience for precise adjustment. The pressing end 212 can be configured to have a certain concave structure according to the shape of the thumb, so as to increase the friction between the thumb and the pressing end 212. The surface of the pressing end 212 can also be configured to be frosted or have certain textures. Such a setting can further increase the friction between the thumb and the pressing end 212, and avoid sliding between the thumb and the pressing end 212, resulting in adjustment failure when adjustment is required.

[0055] In the technical solution of the first embodiment, the adjustment assembly 20 includes a first elastic member (not shown in the figure), which is connected between the driving member 21 and the adjustment structure 22, and the first elastic member pushes the driving member 21 to lock with the limiting structure 23. The first elastic member is provided for the automatic locking of the driving member 21 and the limiting structure 23. Such a setting saves the locking procedure, and the locking procedure can be achieved by contacting the limiting effect of the driving member 21, further simplifying the cumbersome procedures during the operation. The displacement of the insertion rod 211 is achieved by pressing the driving member 21, and the fixation between different tooth grooves is completed, so as to achieve unlocking and locking.

[0056] It should be noted that the atrial appendage clamp delivery handle also includes an actuator control assembly 30 for controlling the atrial appendage clamp to switch between an open and a locked state. After the atrial appendage clamp reaches the specified position, the position of the atrial appendage clamp is first adjusted by the adjustment assembly, and then the atrial appendage clamp is opened by the actuator control assembly 30, and then the position of the atrial appendage clamp is adjusted to a position suitable for clamping, so that the atrial appendage clamp is clamped, and then the structure of the atrial appendage clamp is released to separate the atrial appendage clamp from the end of the actuator, thereby realizing the deployment of the atrial appendage clamp. Further, the actuator is connected to the sliding block in the handle 12 through a harness, and one end of the lever structure in the actuator control assembly 30 is connected to the sliding block, that is, when the lever structure rotates, it will drive the sliding block to move, thereby driving the harness to tighten and release, and the corresponding atrial appendage clamp is opened and closed.

[0057] Furthermore, the lever structure is also provided with a limiting mechanism to prevent the atrial appendage clamp from being directly closed due to misoperation. When the atrial appendage clamp is opened at a suitable position, a small displacement is required. At this time, the atrial appendage clamp needs to be kept in an open state. When the opened atrial appendage clamp reaches the optimal position, the operation of closing the atrial appendage clamp is performed. At this time, the restriction of the limiting mechanism on the lever structure needs to be released before the atrial appendage clamp can be released, thereby reducing misoperation and improving the safety of the operation, and also reducing the time and energy consumed by mistakes. Finally, the atrial appendage clamp is separated from the end of the actuator through the release mechanism.

[0058] like Figure 2 and Figure 3 As shown, in the technical solution of the first embodiment, the adjustment structure 22 includes a sliding cavity 221, the first end of the driving member 21 is slidably disposed in the sliding cavity 221, and the first elastic member is disposed in the sliding cavity 221. The sliding cavity 221 is provided to accommodate the first elastic member on the one hand, and to guide the sliding of the first end of the driving member 21 on the other hand, that is, to push the driving member 21 in a certain manner, thereby achieving automatic locking.

[0059] like Figure 2 and Figure 3 As shown, in the technical solution of the first embodiment, the limiting structure 23 is provided with an inner tooth structure 231, and the driving member 21 is provided with an insertion rod 211 extending in a direction away from the adjustment structure 22, and the insertion rod 211 extends into the teeth of the inner tooth structure 231 to form a lock. The setting of the insertion rod 211 realizes the limit between the limiting structure 23 and the driving member 21, and the inner tooth structure 231 has a plurality of teeth, and there is a certain accommodation gap between adjacent teeth. The accommodation gap accommodates the insertion rod 211 to form a lock. The structure of the insertion rod 211 is simple, which is convenient for manufacturing and controlling shape accuracy, can reduce production costs, and occupies a small space, which is more conducive to the arrangement of other components inside the atrial appendage clamp delivery handle.

[0060] like Figure 2 and Figure 3 As shown, in the technical scheme of embodiment 1, the setting direction of the sliding cavity 221 points to the fixed shaft 111, and the center of the inner tooth structure 231 is set on the axis of the fixed shaft 111, that is, the setting direction of the first elastic member is also pointing to the direction of the fixed shaft 111. Such a setting makes the pressing direction of the driving member 21 always toward the direction of the center of the circle. Such a setting directly acts on the first elastic member when pressed, and the structure is compact, simple and easy to implement.

[0061] In another optional embodiment, the first elastic member can also be arranged along the rotation direction of the driving member 21, that is, the first elastic member pushes the driving member 21, and a structure similar to a ratchet can be arranged between the driving member 21 and the fixed shaft 111. When rotating and advancing, the first elastic member can mortgage the driving member 21 and lock the fixed shaft 111, and can rotate after the elastic force of the first elastic member acts.

[0062] In another optional embodiment, the first elastic member can also be arranged in a direction parallel to the axis of the fixed shaft 11. The first elastic member pushes the driving member 21 to contact the shell, tooth portion or wear-resistant layer arranged on one side of the driving member 21, so as to achieve locking of the driving member 21. When unlocking, a small force can be applied along the setting direction of the first elastic member to separate the driving member 21 from the shell, tooth portion or wear-resistant layer, and then rotate around the fixed shaft 11.

[0063] It should be noted that if Figure 3 As shown, the first end of the driving member 21 is a rod 213; a connecting seat 214 is provided on the side of the rod 213, and the connecting seat 214 and the rod 213 form an L-shaped structure. The first elastic member pushes the connecting seat 214 and then pushes the entire driving member 21 in a direction close to the inner tooth structure 231, so that the insertion rod 211 is inserted between adjacent teeth of the inner tooth structure 231 to limit the rotation of the adjustment component 20. The rod 213 extends outward through the housing 10, and the pressing end 212 is located at the end of the rod 213 away from the housing 10.

[0064] like Figure 2As shown, in the technical solution of the first embodiment, the adjustment component 20 also includes a stranded wire structure 26, which is engaged with the adjustment structure 22, and the stranded wire structure 26 is rotatably connected to the fixed shaft 111. The stranded wire structure 26 is used for winding cables, and the cables can be connected to the control end of the actuator through the connected pipe, so that the operation of the actuator can be adjusted by rotating the cable. It should be noted that the cable can be made of steel wire or a material with high toughness and non-toxic and harmless. The stranded wire structure 26 is engaged with the adjustment structure 22 by a snap-on method, and the stranded wire structure 26 can also pass through the fixed shaft 111 and be rotatably connected thereto. Such an arrangement makes the combination between the stranded wire structure 26 and the adjustment structure 22 closer in the direction of the fixed shaft 111, and the rotation of the adjustment structure 22 can drive the stranded wire structure 26 to rotate, thereby realizing the adjustment of the actuator.

[0065] Furthermore, a cable steering structure is provided on the stranded wire structure 26, and the cable can be arranged to cooperate with the components in the actuator to achieve a pulling and stretching effect through the steering structure, thereby driving the components in the actuator to rotate. The steering structure can be realized by screws and a plate body, and the cable passes through the screws and cooperates with the annular groove on the stranded wire structure 26. The annular groove can guide and change the direction of the cable, so that the cable and the stranded wire structure 26 have a certain friction force, thereby preventing the cable from sliding directly relative to the stranded wire structure 26, and the actuator angle adjustment fails.

[0066] Embodiment 2:

[0067] like Figure 4 and Figure 5 As shown, the second embodiment of the present application provides an atrial appendage clamp delivery handle, the adjustment component 20 includes a fixedly arranged first engaging structure 24, the driving member 21 is fixedly connected to the adjustment structure 22, the first engaging structure 24 and the limiting structure 23 have a locked state and an unlocked state, when the driving member 21 rotates, the first engaging structure 24 and the limiting structure 23 are in an unlocked state, when the driving member 21 is stationary, the first engaging structure 24 and the limiting structure 23 are in a locked state. The driving member 21 is fixedly connected to the adjustment structure 22, and the locking and unlocking of the adjustment structure 22 are achieved by the operation and stop of the driving member 21, avoiding the steps of unlocking first and then adjusting in the prior art, on the one hand, the response speed during the operation is faster, saving operation time, on the other hand, it can avoid the damage of the adjustment component caused by forgetting the unlocking step, affecting the operation process, and can improve the safety of the operation from multiple aspects. The present application effectively solves the problem that the atrial appendage clamp delivery handle in the prior art is not flexible enough to adjust the position and state of the atrial appendage clamp, there is a risk of damage to the conveyor, and affects the safety of the operation.

[0068] It should be noted that the adjustment structure 22 is used to connect the actuator in the auricle clamp conveyor. The specific shape of the actuator is controlled by the rotation of the adjustment structure 22. The self-locking ability of the adjustment structure 22 ensures that the shape of the actuator will not change when the adjustment structure 22 is not operated, and there is no need to unlock when operation is required, thereby ensuring that the deformation and transportation of the actuator is faster and more efficient.

[0069] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, in the technical scheme of embodiment 2, the limiting structure 23 is provided with an inner tooth structure 231, and the first clamping structure 24 includes a first clamping member 241 and a second elastic member 242, and the second elastic member 242 pushes the first clamping member 241 in a direction close to the inner tooth structure 231, and one end of the first clamping member 241 away from the second elastic member 242 is in contact with the inner tooth structure 231.

[0070] The second elastic member 242 is set to push the first engaging member 241 against the inner tooth structure 231, so that the first engaging member 241 can be engaged with the inner tooth structure 231 at any time, thereby ensuring the stability of the actuator's shape in the body. The setting of the inner tooth structure 231 cooperates with the retractable characteristics of the second elastic member 242, so that when the adjustment structure 22 is acted upon by a force, it can move relative to the first engaging member 241 through the teeth of the inner tooth structure 231, and the applied force is divided into two parts, one part compresses the second elastic member 242, and the other part drives the first engaging member 241 to move, thereby achieving self-locking and self-unlocking. It should be noted that the setting of the inner tooth structure 231 makes the displacement of the first engaging member 241 have an adjustable precision limit, that is, the degree of deflection across the distance between a single tooth is equal, and such a setting is conducive to accurately controlling the rotation amount of the adjustment structure 22, and thus better controlling the angle of the actuator during the operation, so as to arrange the atrial appendage clamp at the best angle.

[0071] like Figures 4 to 9As shown, in the technical solution of the second embodiment, there are multiple first engaging structures 24, and one end of each first engaging member 241 away from the second elastic member 242 is in contact with the inner tooth structure 231; the corresponding driving member 21 is also multiple, and the multiple first engaging structures 24 are used to adjust the multiple degrees of freedom of the actuator. Setting the same inner tooth structure 231 to cooperate with multiple first engaging members 241 can save material processing, have a higher degree of integration, and have the same assembly reference. In a specific embodiment, there are two first engaging structures 24, which are respectively used to control the angular relationship between the actuator as a whole and the connecting rod body in the vertical plane and the horizontal plane, so as to realize the change of the angle of the actuator in two directions. After controlling the distance between the end point of the actuator and the left atrial appendage, the cooperation between the atrial appendage clip on the actuator and the left atrial appendage can be adjusted by controlling the two driving members 21.

[0072] In another optional embodiment, there are multiple first engaging structures 24, and the limiting structure 23 is provided with multiple inner tooth structures 231, and one end of each first engaging structure 24 away from the second elastic member 242 is respectively in contact with the corresponding inner tooth structures 231. The difference in this embodiment is that the limiting structure 23 is provided with multiple inner tooth structures 231, and the multiple inner tooth structures 231 are arranged in parallel with each other, and each first engaging member 241 is respectively in contact with each inner tooth structure 231. Such a setting can design the inner tooth structure 231 and the first engaging member 241 for the control of different degrees of freedom according to actual needs, so as to achieve different pushing speeds and actuator adjustment rates, so as to be more suitable for the operation, thereby saving the operation time.

[0073] It should be noted that if Figures 6 to 9 As shown, in the technical solution of the second embodiment, the adjustment structure 22 includes a fixed installation groove 222, a first engaging member 241 is fixedly connected to the first accommodating sleeve 243, a second elastic member 242 is arranged in the first accommodating sleeve 243, and one end of the first accommodating sleeve 243 away from the first engaging member 241 is slidably arranged in the installation groove 222. The second elastic member 242 is arranged in the first accommodating sleeve 243, and such an arrangement makes the second elastic member 242 exactly located between the two cavities, and there will be no leakage area, so that the installation structure at both ends of the second elastic member 242 can be reduced, and the structure is simpler and more compact, and it is also convenient for assembly. The fixed installation groove 222 can accurately realize the positioning of the first engaging member 241 after assembly, so as to adapt to precision medical equipment.

[0074] Furthermore, the first accommodating sleeve 243 can be set to a clearance fit with the mounting groove 222, so that the structure is more compact and the movement of the first engaging member 241 is avoided. During the rotation process, no forces in different directions are generated on the matching first engaging member 241 and the inner tooth structure 231, causing the adjustment structure 22 to be locked and affecting the progress of the operation.

[0075] It should be noted that the end of the first engaging member 241 can be set to an arc shape, and the tooth shape of the inner tooth structure 231 can be set to a trapezoidal, V-shaped or an arc shape with a radius greater than the end of the first engaging member 241. In this way, the matching relationship between the first engaging member 241 and the inner tooth structure 231 is a point-to-surface matching relationship. Such a setting can effectively decompose the force, and the relative friction generated between the two is also smaller, so that relative sliding can be better achieved, thereby achieving the purpose of self-unlocking. It should be noted that the matching relationship of the point-to-surface combination makes the friction between the two relatively small, but the force generated when multiple points and surfaces are combined is also much smaller than the force that can cause the end of the first engaging member 241 to slide, and the self-locking effect will obviously not move, resulting in the angle deflection of the actuator and then failure.

[0076] like Figure 4 and Figure 5 As shown, in the technical solution of the second embodiment, the housing 10 is surrounded by a first housing 15 and a second housing 16, and the first housing 15 and the second housing 16 are fixedly connected by a plurality of jacks and an interference fit of an insertion rod, and the fixed shaft 111 also plays a connecting role. The adjustment component 20 is generally disc-shaped, and the edge of the disc has a rod portion 213 that can be rotated and force applied. The disc-shaped adjustment component 20 can be rotated by pushing the pressing end 212 at the upper end of the rod portion 213. The limiting structure 23 can cover part of the adjustment component 20, that is, the top of the adjustment component 20 can be limited between the limiting structure 23 and the first housing 15 or the second housing 16, and only the pressing end 212 at the upper end of the rod portion 213 extends out of the housing 10.

[0077] The first shell 15 and the second shell 16 also have guide structures for guiding cables, which are arranged on one side of the first shell 15 and the second shell 16 close to the lever structure, respectively, for guiding the cable for releasing the auricle clamp to reduce the risk of cable jamming.

[0078] In the technical solution of the second embodiment, the limiting structure 23 is provided with a plurality of connecting through holes 234, and a plurality of assembly columns are provided in the housing 10, and the assembly columns partially extend into the corresponding connecting through holes 234. That is, the limiting structure 23 is fixed to the housing 10 by providing the assembly columns, and such a setting controls the position of the connecting through holes 234 at multiple points, thereby protecting the limiting structure 23 from rotating and achieving position limiting. Specifically, there are more than two connecting through holes 234, and a single connecting through hole 234 can be completely passed through by an assembly column to achieve fixed connection, or two assembly columns with threaded through holes can pass through the two ends of the connecting through hole 234 from opposite directions, and finally achieve fixed connection through threaded fasteners, and the connection effect is more stable.

[0079] like Figure 4 , Fig.10 and Fig.11 As shown, in the technical solution of the second embodiment, the atrial appendage clamp delivery handle also includes an actuator control component 30, and the actuator control component 30 is used to control the opening and closing of the atrial appendage clamp. The purpose of setting the actuator control component 30 is that when the instrument with the atrial appendage clamp enters the patient's body, the environment space is small. In the case of no clamping, closing the atrial appendage clamp can reduce the volume of the actuator end on the one hand, avoid accidental contact with the patient's body tissue, have higher flexibility, and avoid scratches. On the other hand, it can prevent the atrial appendage clamp from always being in an open state before clamping, resulting in insufficient clamping force after clamping the atrial appendage, and failure of the operation, thereby increasing the success rate of the operation.

[0080] like Fig.10 and Fig.11 As shown, in the technical solution of the second embodiment, the actuator control assembly 30 includes a control rod body 31, a reset structure 32 and an actuator, the control rod body 31 is rotatably connected to the housing 10, the slider 321 in the reset structure 32 is slidably arranged in the housing 10, the control rod body 31 is connected to the reset structure 32, the actuator is connected to the reset structure 32 through a harness, and the control rod body 31 and the housing 10 have a locked state and an unlocked state. The control rod body 31 realizes the opening and closing of the atrial appendage clamp by rotating, and the reset structure 32 is set to open the atrial appendage clamp and then close it without manual closing, and the closing of the atrial appendage clamp can be completed by resetting the reset structure 32.

[0081] The control rod body 31 and the housing 10 have a locked state and an unlocked state. The idea of ​​this arrangement is that when the actuator reaches a suitable position and adjusts the angle, the atrial appendage clamp opens. At this time, the control rod body 31 needs to be turned to close so that the atrial appendage clamp opens. The opening of the atrial appendage clamp will produce an elastic effect, forcing the control rod body 31 to open (such as Fig.10 As shown in the figure, if the control rod body 31 is directly closed without control, it is not conducive to the operator's control, and there may be problems with the closing of the atrial appendage clamp, resulting in failure of the operation. A locked state is set, that is, the control rod body 31 will not be opened after opening the atrial appendage clamp, and the atrial appendage clamp is kept in an open state, so that further movement can be performed, and the operator does not need to apply force to control the control rod body 31 to remain in a closed state. This can save the operator's force application and reduce the occurrence of fatigue. It can also save force and focus attention and strength on the release position of the atrial appendage clamp. Such a surgery has a better effect and is more beneficial to the health of the patient.

[0082] like Figures 10 to 12As shown, in the technical solution of the second embodiment, the control rod body 31 is provided with an arc-shaped groove body 311, and the rotation center of the arc-shaped groove body 311 coincides with the rotation center of the control rod body 31, and the housing 10 is provided with an unlocking structure 17, and the unlocking structure 17 can slide through the arc-shaped groove body 311, and the unlocking structure 17 and the arc-shaped groove body 311 have a locked state and an unlocked state. The setting of the arc-shaped groove body 311 can realize the shape transformation of the unlocking structure 17 in coordination with the rotation of the control rod body 31, and will not cause interference, the structure is compact, the effect is stable, and such a setting avoids setting the unlocking structure 17 as a component that needs to move along the plane where the arc-shaped groove body 311 is located, so that the setting method of the unlocking structure 17 is simpler, and an overly complicated linkage scheme design is not required. The rotation center of the arc-shaped groove body 311 coincides with the rotation center of the control rod body 31, and the precision control during the processing is better, which is conducive to production.

[0083] like Figures 10 to 14 As shown, in the technical scheme of embodiment 2, the unlocking structure 17 includes a fourth elastic member 171 and an unlocking button 172, the unlocking button 172 includes a pressing section 1721, a sliding section 1722 and a locking section 1723 which are arranged in sequence, the fourth elastic member 171 pushes the shell 10 and the locking section 1723 away from one end of the sliding section 1722 respectively, the arc-shaped groove body 311 is provided with a connected engaging groove section 3111 and a sliding groove section 3112, the circumferential dimension of the sliding section 1722 is smaller than the circumferential dimension of the locking section 1723, the sliding section 1722 is clearance-matched with the sliding groove section 3112, and the locking section 1723 is clearance-matched with the engaging groove section 3111. The arrangement of the engaging groove section 3111 and the sliding groove section 3112 realizes the switching between the locked state and the unlocked state, and the push-pushing effect of the fourth elastic member 171 can effectively realize automatic locking, that is, when the control rod body 31 rotates to the maximum position in the direction close to the handle 12, the locking section 1723 enters the engaging groove section 3111 to form a limit position under the action of the fourth elastic member 171, and the sliding section 1722 is separated from the sliding groove section 3112, and the control rod body 31 can no longer slide, realizing locking. When unlocking is required, just press The pressing section 1721, at this time, the sliding section 1722 enters the engaging groove section 3111, and there is a large gap between the two, and the freedom is released. Since the control rod body 31 has a rotating shaft center, under the action of the force transmitted from the end and the action of the reset structure 32, the control rod body 31 rotates in the direction away from the handle 12, so that the sliding section 1722 enters the sliding groove section 3112 again, completing the closure of the auricle clamp. Such a setting has a compact structure, a definite function, a clear release logic, and a reliable safety measure, which is conducive to the progress of the operation.

[0084] Furthermore, if Fig.12As shown, a receiving groove 3113 is provided on the side of the arcuate groove body 311 facing the fourth elastic member 171, and the receiving groove 3113 is used to partially accommodate the locking segment 1723, that is, the locking segment 1723 can slide in the receiving groove 3113. Such a setting can increase the structural strength of the arcuate groove body 311 on the one hand, and increase the degree of fit between the arcuate groove body 311 and the unlocking structure 17 on the other hand, limiting its degree of freedom except for the rotation direction, and under the push action of the fourth elastic member 171, the required displacement is smaller, and the fourth elastic member 171 can use a spring with less elasticity, etc., which is more conducive to unlocking.

[0085] like Fig.14 As shown, in order to better accommodate the fourth elastic member 171, an accommodating cavity is provided in the locking section 1723, and the fourth elastic member 171 partially extends into the accommodating cavity. Such a setting is conducive to assembly, and can limit the circumferential freedom of the elastic member, and can also reduce the space occupied in the length direction thereof, and the structure is more streamlined.

[0086] like Fig.10 and Fig.11 As shown, in the technical solution of the second embodiment, the housing 10 is provided with a sliding groove 18, and the reset structure 32 includes a slider 321, a fifth elastic member 322 and a push rod 323. The slider 321 is slidably arranged in the sliding groove 18, the slider 321 is rotatably connected to the push rod 323, and the end of the push rod 323 away from the slider 321 is rotatably connected to the control rod 31, and the fifth elastic member 322 is connected between the slider 321 and the housing 10, and the fifth elastic member 322 applies a force to the slider 321 to push the push rod 323. The setting of the reset structure 32 can realize automatic reset, reduce the force of the operator on the rotation of the control rod 31, save physical strength and be more conducive to control accuracy. The setting of the slider 321 and the sliding groove 18 ensures the accuracy of the sliding direction of the slider 321 after the rod body 323 is pushed against the rod body 323 during the rotation of the control rod body 31, thereby ensuring the accuracy of controlling the opening of the auricle clamp, and the linkage setting converts the rotation of the control rod body 31 into the sliding of the slider 321, the structure is simple and compact, and the control effect is better.

[0087] It should be noted that a sliding groove 18 can be provided on both parts of the shell forming the handle 12, and the slider 321 can slide in the two sliding grooves 18. Such sliding will not produce circumferential movement, and the control is more precise. The slider 321 can also move in the sliding groove 18 through one or more sliding rods, and the sliding process is smoother, and the guiding effect of multiple sliding rods is more prominent. The fifth elastic member 322 is a spring, one end of which is fixedly connected to the shell 10, and the other end is fixedly connected to the hook-shaped structure of the slider 321 away from the push rod body 323. The spring is always in a stretched state, that is, a pulling force is continuously applied, so that the slider 321 slides in the direction close to the push rod body 323, that is, the reset condition is always maintained.

[0088] Embodiment three:

[0089] like Figures 15 to 19 As shown, the third embodiment of the present application provides an auricle clamp delivery handle, the driving member 21 is fixedly connected to the adjustment structure 22, the adjustment assembly 20 includes a fixedly arranged outer tooth structure 25, the limiting structure 23 is provided with a second engaging member 232 and a third elastic member 233, the third elastic member 233 pushes the second engaging member 232 in the direction close to the outer tooth structure 25, when the driving member 21 rotates, the second engaging member 232 and the outer tooth structure 25 are in an unlocked state, when the driving member 21 is stationary, the second engaging member 232 and the outer tooth structure 25 are in a locked state. The difference from the second embodiment is that in the third embodiment, the second engaging member 232 and the third elastic member 233 are provided on the limiting structure 23, the inner tooth structure 231 is cancelled, and the outer tooth structure is provided on the adjustment assembly 20, and the principle of realizing unlocking and locking is the same as that of the first embodiment, which is realized by the cooperation of the engaging member and the tooth structure, thereby ensuring the stability of the shape of the actuator in the body. Compared with the technical solution of the first embodiment, the second and third embodiments both adopt an automatic unlocking method, which is simpler to operate and reduces the fixed process of unlocking and locking, and the atrial appendage clamp delivery handle will not fail due to operational errors.

[0090] It should be noted that the difference between Example 3 and Example 2 also lies in that, during use, in addition to the force of the third elastic member 233, the gravity of the second engaging member 232 will also cause the second engaging member 232 to engage with the outer tooth structure 25. This setting is because the setting of the outer tooth structure 25 results in a larger spacing between the teeth, and a larger angle than the center of the circle corresponding to the inner teeth. The second engaging member 232 is relatively easier to slide between the teeth. Therefore, it is necessary to set the third elastic member 233 to apply a pushing force to the outer tooth structure 25, so that the engagement between the second engaging member 232 and the outer tooth structure 25 is more stable, which is more conducive to the arrangement of the auricle clamp.

[0091] Furthermore, the outer tooth structure 25 has high precision in controlling the displacement of the second engaging member 232, and the corresponding rotation angles between adjacent tooth components are equal, that is, the deflection angles for spanning between single teeth are equal. Such a setting is conducive to accurately controlling the rotation amount of the adjustment structure 22, and further better controlling the angle of the actuator during surgery, so as to arrange the atrial appendage clamp at the optimal angle.

[0092] In the technical solution of the third embodiment (not shown in the figure), there are multiple adjustment components 20, and the external tooth structure 25 of each adjustment component 20 is in contact with the second engaging member 232; that is, a single second engaging member 232 realizes the engagement of multiple external tooth structures 25, the structure is more compact, and the mass of the second engaging member 232 can be increased to ensure the engagement effect. Specifically, the second engaging member 232 can be arranged in a strip shape or have multiple engaging ends that can correspond to multiple external tooth structures 25.

[0093] In another optional embodiment, there are multiple adjustment components 20, and the second engaging member 232 is correspondingly arranged as multiple, and the outer tooth structure 25 of each adjustment component 20 contacts the corresponding second engaging member 232. Multiple adjustment components 20 are used to adjust multiple degrees of freedom of the actuator. Such a setting makes the adjustment standards of multiple adjustment components 20 the same, avoiding the possibility of movement. Such a setting can design the outer tooth structure 25 and the second engaging member 232 for the control of different degrees of freedom according to actual needs, so as to achieve different pushing speeds and actuator adjustment rates, so as to be more suitable for the operation, thereby saving the operation time.

[0094] like Figures 15 to 19 As shown, in the technical solution of the third embodiment, the limiting structure 23 is further provided with a fixed installation groove 237, and the limiting structure 23 also includes a second accommodating sleeve 236, the second engaging member 232 and the second accommodating sleeve 236 are an integrally formed structure, and the second engaging member 232 extends in a direction away from the second accommodating sleeve 236, the third elastic member 233 is arranged in the second accommodating sleeve 236, and one end of the second accommodating sleeve 236 away from the second engaging member 232 is slidably arranged in the installation groove 237. The installation groove 237 is arranged to facilitate the fixed installation of the second accommodating sleeve 236 and the installation of the third elastic member 233 during assembly, and the installation groove 237 is specifically a preset hole on the limiting structure 23. During assembly, the third elastic member 233 is first installed in the second accommodating sleeve 236, and then the entire assembled second accommodating sleeve 236 is installed into the installation groove 237. After the second accommodating sleeve 236 is assembled, it is abutted against the external tooth structure 25 on the adjustment structure 22, and then the adjustment structure 22 is passed through the fixed shaft 111 to complete the assembly.

[0095] It should be noted that the second accommodating sleeve 236 can also be set to a clearance fit with the mounting groove 237, so that the structure is tighter and the second accommodating sleeve 236 can be prevented from moving during use, causing the adjustment structure 22 to fail or even completely fail.

[0096] The end of the second engaging member 232 can also be set to an arc shape, and the tooth shape of the external tooth structure 25 can be set to a trapezoidal, V-shaped or arc shape with a radius larger than the size of the end of the second engaging member 232. In this way, the matching relationship between the end of the second engaging member 232 and the external tooth structure 25 is a point-to-surface matching relationship. Such a setting can effectively decompose the force, and the relative friction generated between the two is also smaller, so that relative sliding can be better achieved, thereby achieving the purpose of self-unlocking. It should be noted that the matching relationship of the point-to-surface combination makes the friction between the two relatively small, but the force generated when multiple points and surfaces are combined is also much smaller than the force that can cause the end of the second engaging member 232 to slide, and the self-locking effect will obviously not move, resulting in the angle deflection of the actuator and then failure.

[0097] It should be noted that, when multiple second engaging members 232 are set up, different pop-up heights and pop-up positions can be selected between the second engaging members 232 and the mounting groove 237. Such a setting avoids the risk of mutual influence between the multiple external tooth structures 25. Such a setting has a certain fault-tolerant property. When there is no mutual influence, the difficulty of manufacturing and assembly is reduced, which is more conducive to production and implementation.

[0098] In the technical solution of the third embodiment, the limiting structure 23 is provided with a plurality of connecting through holes 234, and a plurality of assembly columns are provided in the housing 10, and the assembly columns partially extend into the corresponding connecting through holes 234. That is, the limiting structure 23 is fixed to the housing 10 by providing the assembly columns, and such a setting controls the position of the connecting through holes 234 at multiple points, thereby protecting the limiting structure 23 from rotating and achieving position limiting. Specifically, there are more than two connecting through holes 234, and a single connecting through hole 234 can be completely passed through by an assembly column to achieve fixed connection, or two assembly columns with threaded through holes can pass through the two ends of the connecting through hole 234 from opposite directions, and finally achieve fixed connection through threaded fasteners, and the connection effect is more stable.

[0099] like Fig. 20As shown, the fourth embodiment of the present application provides an auricle clamp delivery handle, and the fourth embodiment is improved on the basis of the second embodiment. Specifically, the limiting structure 23 is an arched structure, and plug-in connectors 235 are provided at both ends of the limiting structure 23, and the housing 10 is correspondingly provided with a plug-in portion 14, and each plug-in connector 235 is respectively plugged into the corresponding plug-in portion 14. That is, the two ends of the limiting structure 23 are fixedly connected by plugging, and the above-mentioned solution is used for fixed connection, the structure is simple and easy to process, and the corresponding limiting structure 23 and the housing 10 can simplify their connection structure, which is more conducive to assembly.

[0100] It should be noted that if Fig. 20 As shown, in the technical solution of the fourth embodiment, the housing 10 is provided with a through-hole plug-in portion 14 for installing the plug-in member 235 at a position close to the housing body 11, and the housing 10 is provided with a countersunk hole plug-in portion 14 for installing the plug-in member 235 at a position close to the handle 12. Such a configuration enables the adjustment assembly 20 to drive the driving member 21 to rotate and generate a force during operation, so that the limiting structure 23 has a tendency to move in the direction close to the handle 12 after being subjected to force, that is, the countersunk hole plug-in portion 14 can effectively resist the limiting structure 23. When the through-hole plug-in portion 14 is installed, a longer plug-in portion 14 can be provided to increase the connection strength at its assembly position.

[0101] Furthermore, a step is formed between the connector 235 and the main body of the limiting structure 23, and the step abuts against the edge of the shell 10 after assembly. The step is set to abut the connector 235 when it is extended into the position, and the shell 10 can easily apply a thrust to the connector 235 through its structure. During the specific assembly, the arched limiting structure 23 can be pushed through the step to achieve a good fixed state.

[0102] like Fig.21 As shown, the fifth embodiment of the present application provides an auricle clamp delivery handle, the limiting structure 23 is an arched structure, the two ends of the limiting structure 23 are provided with plug-in components 235, the housing 10 is correspondingly provided with plug-in parts 14, and each plug-in component 235 is respectively plugged into the corresponding plug-in part 14. The difference between the fifth embodiment and the fourth embodiment is that the fifth embodiment is an improvement based on the third embodiment.

[0103] On the second aspect, Example 6 of the present application provides an atrial appendage clamp conveyor, which includes an atrial appendage clamp conveying handle and an actuator. The atrial appendage clamp conveying handle is the atrial appendage clamp conveying handle of any one of Examples 1 to 5, and the actuator is connected to the adjustment structure 22 via a cable, and the atrial appendage clamp is deployed on the actuator. The use of the atrial appendage clamp conveying handle in Example 1 or Example 2 can effectively control the specific form of the actuator during surgery, and can be better operated during adjustment, avoiding the phenomenon of failure of the adjustment structure, and can also effectively improve the operating efficiency of the surgery, improve the safety of the surgery, and provide greater protection for patients. It should be noted that such an atrial appendage clamp conveyor is more suitable for patients with poor physical fitness, and through a minimally invasive surgical mode, it reduces the possibility of bleeding and performs left atrial appendage clamping, which is a better choice for patients who cannot be treated with anticoagulant drugs.

[0104] In a third aspect, the present application further provides an auricle clamp delivery system, the auricle clamp delivery system comprising the auricle clamp delivery device as in Example 6. Since the auricle clamp delivery device and the auricle clamp delivery handle described above already have the above technical effects, the auricle clamp delivery system having the auricle clamp delivery device should also have similar technical effects, so no further description will be given here.
