Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an anchoring component delivery system and its handle. Background Technology
[0002] Benign prostatic hyperplasia (BPH) is one of the most common medical conditions affecting men, especially older men. The prostate gland enlarges throughout a man's life. In some men, the prostatic capsule surrounding the prostate may prevent further enlargement, causing the internal regions of the prostate to compress the urethra. This pressure in the urethra increases resistance to urine flow through the area of the urethra surrounded by the prostate. Currently, the main minimally invasive surgical treatment for BPH symptoms is prostate suspension surgery, a minimally invasive procedure that uses a transurethral implant to dilate the obstructed segment of the prostatic urethra. The principle is to implant a miniature urethral suspension device to suspend and compress the enlarged, obstructed lateral lobes of the prostate, thereby dilating the obstructed prostatic urethra and improving the patient's obstructive symptoms. However, this surgery requires specific equipment.
[0003] For example, Chinese patent document application number 202411270736.0 discloses an anchoring component delivery system and its handle and magazine. The magazine includes a puncture needle tube, a push-pull tube, a puncture needle connector, a shearing component, a pushing component, and a support component. The support component is installed between the shearing component and the pushing component. The support component has two position states: when the support component is in the first position, it limits the backward movement of the shearing component but does not limit the pushing component; when the support component is in the second position, it limits the forward movement of the pushing component but does not limit the shearing component. The structure and operation of this invention are more reasonable and simple, easy to operate, less prone to errors, and more reliable. Its shortcomings are that when unlocking the above device, the force required to unlock the trigger is between 60 and 70 N, which is difficult to use. In addition, the above patented product involves too many parts, resulting in excessive material costs, installation costs, and installation difficulty, and an increased probability of component damage. Summary of the Invention
[0004] To address the aforementioned problems of difficult use, installation, and high production costs associated with the front anchoring handle, this invention aims to provide an anchoring component delivery system and its handle, facilitating surgical procedures, reducing the number of parts, and lowering costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A handle for an anchor delivery system, comprising:
[0007] One handle housing;
[0008] An energy storage slider is installed in the handle housing in a way that allows it to slide back and forth. When the energy storage slider moves backward to the energy storage position, it is connected to the handle housing through a locking mechanism, which restricts its forward movement. It is also connected to the handle housing through an energy storage spring, which gives it a tendency to move forward. When the locking mechanism fails, the energy storage slider can move forward under the action of the energy storage spring.
[0009] An energy storage component is installed in the handle housing in a way that allows it to slide back and forth. The energy storage component is equipped with a push slider that can slide up and down. The push slider can be connected to or separated from the energy storage slider: when the push slider is connected to the energy storage slider, the energy storage component can drive the energy storage slider to move backward; when the push slider is separated from the energy storage slider, the energy storage component cannot drive the energy storage slider to move.
[0010] A cut-off trigger lever is installed inside the handle housing in a way that allows it to slide up and down.
[0011] The locking mechanism includes a knob, which is rotatably mounted in the handle housing and given a rotational tendency by a spring. The knob includes a hook for cooperating with the energy storage slider and a drive post for cooperating with the energy storage component. When the energy storage slider moves backward to the energy storage position, the hook of the knob can hook the energy storage slider to lock it, thereby restricting the energy storage slider from moving forward. When the energy storage component moves backward again, the energy storage component applies force to the drive post on the knob, thereby causing the knob to deflect until the hook on the knob disengages from the energy storage slider to unlock it.
[0012] It also includes an unlocking component disposed within the handle housing and capable of engaging with a push slider on the energy storage component. The unlocking component has at least two position states: when the unlocking component is in the first position state, the push slider can connect with the energy storage slider, thereby enabling the energy storage component to drive the energy storage slider to move backward to the energy storage position; when the unlocking component is in the second position state, the unlocking component can force the push slider to move downward and retract, thereby preventing the push slider from contacting and connecting with the energy storage slider, and the energy storage component cannot drive the energy storage slider to move.
[0013] Preferably, the device also includes a first motor for driving the energy storage component to move back and forth and a second motor for driving the shearing trigger rod to move up and down. The unlocking component is connected to the shearing trigger rod and is controlled by the shearing trigger rod to switch between multiple position states: when the shearing trigger rod is in the locked position, the unlocking component is in the first position state; when the shearing trigger rod is in the unlocked position, the unlocking component is in the second position state.
[0014] Preferably, the unlocking position, locking position, and triggering position of the shearing trigger lever are arranged sequentially from bottom to top, and a second sensor for detecting the position status of the shearing trigger lever is installed inside the handle housing.
[0015] Preferably, the unlocking component is a swing arm, one end of which is movably connected to the handle housing, and the other end of which is movably connected to the shearing trigger rod. When the energy storage component moves back and forth, it pushes the slider to move back and forth between the two ends of the swing arm.
[0016] Preferably, a stop post is provided on the push slider, located below the swing arm. When the shearing trigger rod is in the locked position, the swing arm does not apply downward pressure to the stop post, and the push slider in the ejected state can connect with the energy storage slider, allowing the energy storage component to drive the energy storage slider to move backward to the energy storage position. When the second motor drives the shearing trigger rod to move downward to the unlocked position, the shearing trigger rod drives the swing arm to rotate downward. Thus, when the energy storage component moves backward, the stop post is pressed down by the swing arm, and the push slider retracts. At this time, the push slider and the energy storage slider are vertically misaligned and separated. When the second motor drives the shearing trigger rod to move upward to the trigger position, the shearing trigger rod drives the swing arm to rotate upward. The swing arm does not apply downward pressure to the stop post, and the shearing trigger rod triggers the push shearing mechanism to clamp and cut the thread.
[0017] Preferably, the handle housing is provided with a first button for initiating the puncture procedure, a second button for initiating the needle return and energy storage procedure, and a third button for initiating the cutting procedure.
[0018] Preferably, the handle housing is provided with three indicator lights that illuminate in relation to the pressing status of the three buttons to indicate the current action sequence status.
[0019] Preferably, the unlocking component is a swing arm, with its front end hinged to the handle housing and its rear end movably connected to the shearing trigger rod through an oblong hole.
[0020] Preferably, the bottom of the energy storage slider is provided with a first stop block, the hook on the knob corresponds to the position of the first stop block, and the knob is mounted on the handle housing by a torsion spring.
[0021] An anchor conveying system includes a handle for an anchor conveying system as described above.
[0022] This invention, by adopting the above-mentioned technical solution, combines two knobs in the prior art into one knob, and sets an energy-storing latch (hook) on the knob to lock the energy-storing slider. The energy-storing component applies force to one foot (drive post) of the knob to rotate, thereby unlocking the energy-storing slider. Furthermore, an unlocking component controls the connection or separation between the push slider and the energy-storing slider. This allows the energy-storing component not only to drive the energy-storing slider to store energy but also to quickly unlock the energy-storing slider for firing and puncture. It also eliminates the need for complex structures such as safety buttons, reduces parts, lowers costs, and uses motor-driven control, making operation more convenient and easier, greatly improving the doctor's comfort and facilitating surgical procedures.

Therefore, they should not be construed as limitations on this utility model.
[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

The other two sides perpendicular to the front-back direction are divided into left and right. The surgical end of the instrument is the distal end, and the operating end is the proximal end.
[0046] Example 1:
[0047] An anchor delivery system includes a handle and a magazine, the magazine being removably and replaceably mounted on the handle, the handle transferring its stored mechanical energy to the magazine to deliver the implant to the patient.
[0048] For magazines used in anchor delivery systems, see the various embodiments disclosed in patent document CN118873218A, or other similar structures that achieve the same function.
[0049] like Figure 1 and Figure 2 A handle for an anchor conveying system is shown, comprising:
[0050] One handle housing;
[0051] An energy storage slider 7 is disposed in the handle housing in a manner that allows it to slide back and forth and can be connected to the piercing needle connector in the magazine for synchronous movement. When the energy storage slider 7 moves backward to the energy storage position, it is connected to the handle housing through a locking mechanism, thereby restricting its forward movement. It is also connected to the handle housing through an energy storage spring, thereby giving it a tendency to move forward. When the locking mechanism fails, the energy storage slider 7 can move forward under the action of the energy storage spring.
[0052] An energy storage component 30 is provided inside the handle housing in a manner that allows it to slide back and forth. The energy storage component is provided with a push slider 6 that can slide up and down. The push slider 6 can be connected to or separated from the energy storage slider 7: when the push slider 6 is connected to the energy storage slider 7, the energy storage component can drive the energy storage slider 7 to move backward; when the push slider 6 is separated from the energy storage slider 7, the energy storage component cannot drive the energy storage slider 7 to move.
[0053] A shearing trigger rod 15 is installed in the handle housing in a manner that allows it to slide up and down.
[0054] A first motor 41 for driving the energy storage component 30 to move back and forth;
[0055] A second motor 42 is used to drive the shear trigger rod 15 to move up and down.
[0056] In this preferred embodiment, the locking mechanism includes a knob 10, which is rotatably mounted in the handle housing and given a rotational tendency by a spring. The knob 10 includes a hook post 10-1 for correspondingly engaging with the energy storage slider 7 and a drive post 10-2 for correspondingly engaging with the energy storage component 30. Thus, when the energy storage slider 7 moves backward to the energy storage position, the hook post 10-1 of the knob 10 can hook the energy storage slider 7 to lock it, thereby restricting the energy storage slider 7 from moving forward. When the energy storage component continues to move backward, the energy storage component applies force to the drive post 10-2 on the knob 10, thereby causing the knob 10 to deflect until the hook post 10-1 on the knob 10 disengages from the energy storage slider 7 to unlock it.
[0057] In this preferred embodiment, an unlocking component is further included, which is disposed within the handle housing and can move in conjunction with the push slider on the energy storage component. The unlocking component has at least two position states: when the unlocking component is in the first position state, the push slider 6 can connect with the energy storage slider 7, thereby enabling the energy storage component to drive the energy storage slider 7 to move backward to the energy storage position; when the unlocking component is in the second position state, the unlocking component can force the push slider 6 to move downward, thereby making the push slider and the energy storage slider 7 no longer in contact, and the energy storage component cannot drive the energy storage slider 7 to move. This achieves the unlocking between the push slider and the energy storage slider, and the energy storage slider can be fired and pierced under the action of the energy storage spring.
[0058] This design combines two knobs from existing technologies into one, with a storable latch (hook) on the knob to lock the storable slider. The storable component applies force to one foot (drive post) of the knob, causing it to rotate and unlocking the storable slider. Furthermore, an unlocking mechanism controls the connection or separation between the push slider and the storable slider. This allows the storable component to not only drive the storable slider to store energy but also to quickly unlock it for firing and puncture. It eliminates the need for complex structures such as safety mechanisms, and uses a motor-driven control system, making operation more convenient and easier, greatly improving the surgeon's comfort and facilitating the surgical procedure.
[0059] like Figure 2 As shown in the preferred embodiment, the handle housing includes an upper housing 1 and a lower housing 2 fixedly connected as one piece. The upper housing 1 is provided with a magazine well for holding the magazine. Both the upper housing 1 and the magazine well are provided with a groove for the connecting post on the puncture needle connector to pass through. The connecting post is connected to the slot on the energy storage slider 7 to realize the synchronous movement of the puncture needle connector and the energy storage slider 7.
[0060] In this preferred embodiment, the front and rear ends of the handle housing are respectively provided with an endoscope channel 21 and an endoscope lock 22 for connecting the endoscope.
[0061] In this preferred embodiment, such as Figure 2 As shown, the energy storage component 30 is slidably mounted inside the handle housing via a guide rod and is driven to move back and forth by a first motor 41. A first sensor 41-1 for detecting the position status of the energy storage component is installed inside the handle housing. The first sensor 41-1 is connected to the main control circuit board 35, which is connected to the first motor 41 and controls the stroke of the first motor 41 accordingly.
[0062] In this preferred embodiment, the energy storage component 30 has an energy storage groove on its upper part, and a first compression spring and a push slider 6 disposed on the upper part of the first compression spring are disposed in the energy storage groove. In this way, under the natural state, the push slider is in an extended state under the pushing force of the compression spring, so that it can come into contact with the energy storage slider 7 and drive the energy storage slider to move. In other embodiments, the push slider can also be connected to the energy storage component by a tension spring or the like.
[0063] In this preferred embodiment, the energy storage spring is a second compression spring 9. More preferably, the energy storage slider 7 is loosely fitted onto a guide shaft 8 fixed at both ends to the lower housing 2. The left end of the energy storage slider 7 abuts against the second compression spring 9, and the guide shaft 8 passes through the second compression spring 9. Thus, the energy storage slider can slide back and forth along the guide shaft, and the second compression spring, acting as the energy storage spring, provides the energy storage slider with a forward movement tendency. In other embodiments, the energy storage spring can also be a tension spring.
[0064] In this preferred embodiment, both the handle housing and the magazine body are provided with through holes through which one end of the trigger rod 15 can be cut off. The cut-off end of the trigger rod 15 passes through the through hole and extends into the magazine to unlock the push-locking component.
[0065] In this preferred embodiment, the unlocking component is connected to the shearing trigger rod 15, and the shearing trigger rod 15 controls the unlocking component to switch between multiple position states: when the shearing trigger rod is in the locked position, the unlocking component is in the first position state; when the shearing trigger rod is in the unlocked position, the unlocking component is in the second position state. Thus, the shearing trigger rod 15 has multiple stopping positions during its up-and-down movement: a locked position, an unlocked position, and a trigger position for unlocking the push-shear mechanism to release the proximal anchor and cut the seam. The shearing trigger rod achieves "multi-purpose functionality," reducing the number of parts, lowering costs, and making operation more convenient.
[0066] In this preferred embodiment, the unlocking position, locking position, and triggering position of the shearing trigger lever 15 are arranged sequentially from bottom to top. A second sensor 42-1 for detecting the position status of the shearing trigger lever is installed inside the handle housing. The second sensor 42-1 is connected to the main control circuit board 35, which is connected to the second motor 42 and controls the stroke of the second motor 42 accordingly.
[0067] In this preferred embodiment, such as Figure 2As shown, the unlocking component is a swing arm 14. One end of the swing arm 14 is movably connected to the handle housing, and the other end of the swing arm 14 is movably connected to the shearing trigger rod 15. When the energy storage component 30 moves back and forth, it pushes the slider 6 to move back and forth between the two ends of the swing arm 14. A stop post 6-1 is provided on the slider 6, and the stop post 6-1 is located below the swing arm 14. When the shearing trigger rod 15 is in the locked position, the swing arm 14 does not apply downward pressure to the stop post 6-1. The push slider 6, which is in the ejected state, can connect with the energy storage slider 7, so that the energy storage component can drive the energy storage slider 7 to move backward to the energy storage position. When the second motor 42 drives the shearing trigger rod 15 to move downward to the unlocked position, the shearing trigger rod 15 drives the swing arm 14 to rotate downward. Thus, when the energy storage component moves backward, the stop post 6-1 is subjected to downward pressure by the swing arm 14, pushing the slider 6 into the energy storage groove 3-2. At this time, the push slider 6 and the energy storage slider 7 are misaligned and separated, unlocking the push slider and the energy storage slider. When the second motor 42 drives the shearing trigger rod 15 to move upward to the trigger position, the shearing trigger rod 15 drives the swing arm 14 to rotate upward. The swing arm 14 does not apply downward pressure to the stop post 6-1. The shearing trigger rod 15 pushes the push locking member in the magazine to move, thereby unlocking the push component. The push shearing mechanism performs the clamping and cutting of the sewing thread. This structure is simple and reasonable, the operation is stable and reliable, there are few parts, and the cost is low.
[0068] Further preferably, the front end of the swing arm 14 is hinged to the handle housing, and the rear end of the swing arm 14 is movably connected to the upper part of the shear trigger rod 15 through an oblong hole. Even further preferably, the upper part of the shear trigger rod 15 is provided with a fourth protrusion 15-1, one end of the swing arm 14 is fitted onto the fourth protrusion 15-1 through the oblong hole, and the other end of the swing arm 14 is fixed to the third protrusion 2-1 of the lower housing 2, and the swing arm 14 can rotate around the third protrusion 2-1. This structure is simple and reasonable, the action is stable and reliable, there are few parts, and the cost is low.
[0069] In this preferred embodiment, such as Figure 11 As shown, a first stop block 7-1 is provided at the bottom of the energy storage slider 7, and the hook post 10-1 on the knob 10 corresponds to the position of the first stop block. The knob 10 is fixedly mounted on the handle housing by a torsion spring. In other embodiments, the knob can also be given a rotational tendency by a compression spring or a tension spring.
[0070] In this preferred embodiment, such as Figure 2 and Figure 3 As shown, the handle housing is equipped with a first button 31, a second button 32, a third button 33, a power switch 34 and an indicator light 40, and the handle housing is equipped with a main control circuit board 35, a battery 36 and a Type-C power board 37.
[0071] The first button 31 is used to initiate the puncture procedure, the second button 32 is used to initiate the needle return and energy storage procedure, and the third button 33 is used to initiate the cutting procedure. Three indicator lights 40 illuminate corresponding to the pressed status of the three buttons to indicate the current procedure status. Detailed explanation follows:
[0072] 1. Puncture procedure: such as Figure 4 As shown, in the initial state, the energy storage slider 7 is in the energy storage position. The first stop block 7-1 at the bottom of the energy storage slider 7 is locked by the hook post 10-1 of the knob 10, thus restricting its forward movement. It is connected to the handle housing through the energy storage spring, thus giving it a tendency to move forward. At this time, the shear trigger rod 15 is in the unlocked position, and the swing rod 14 is in the second position. The swing rod 14 will form a downward slope from front to back to press the push slider 6 back, so that the push slider and the energy storage slider 7 are no longer in contact.
[0073] Pressing the first button 31 causes the first motor 41 to drive the energy storage component 30 to slide backward. This pushes the stop post 6-1 on the push slider 6 to be pressed down by the swing arm 14, causing the push slider 6 to retract. At this point, the push slider 6 and the energy storage slider 7 are vertically misaligned and separated. The push slider 6 will not affect the forward movement of the energy storage slider 7 for firing and piercing. When the drive post 10-2 is impacted by the energy storage component 30 and retracts backward, the knob 10 rotates, and the first stop block 7-1 at the bottom of the energy storage slider 7 disengages from the hook post 10-1 of the knob 10, unlocking the energy storage slider 7. Figure 5 As shown. Under the action of the second compression spring 9, the energy storage slider 7 slides forward rapidly, driving the piercing needle connector and piercing needle in the magazine to fire and pierce. Under the action of the torsion spring, the knob 10 rotates clockwise to the initial position, as shown. Figure 6 As shown.
[0074] 2. Back-needle energy storage process: Pressing the second button 32, the second motor 42 drives the shear trigger rod 15 to move upward to the locked position. The swing arm 14 is in the first position and does not affect the upward push of the slider 6. The push slider 6 can connect with the energy storage slider 7 to drive the energy storage slider 7 to move backward. The first motor 41 drives the energy storage component 30 to move backward and drives the energy storage slider 7 to move backward to the energy storage position. The first stop block 7-1 at the bottom of the energy storage slider 7 is locked by the hook post 10-1 of the knob 10. Figure 7 As shown; during this process, the energy storage slider 7 drives the puncture needle connector and puncture needle inside the magazine to retract and tighten the suture. The first motor 41 drives the energy storage component 30 to move forward and reset, as shown. Figure 8 As shown.
[0075] 3. Cutting process: Press the third button 33, as shown. Figure 9As shown, the second motor 42 drives the shearing trigger rod 15 upward to the trigger position. The shearing trigger rod 15 pushes the push locking member inside the magazine, thereby unlocking the push shearing mechanism and completing the release of the proximal anchor and the cutting of the seam. The second motor 42 drives the shearing trigger rod 15 downward to reset, as shown. Figure 10 As shown.
[0076] In this way, three buttons are used to perform three surgical procedures, and three indicator lights are used to display the status of the corresponding procedures. The main control circuit board automatically controls the two motors to perform the corresponding surgical procedures based on the button presses. This not only facilitates the surgeon's operation but also reduces the risk of misoperation.
[0077] This embodiment also discloses an anchor delivery system using the above-described handle.
[0078] Other structures and usage methods not described in this embodiment can be readily obtained by those skilled in the art by referring to Embodiment 1.
[0079] Example 2:
[0080] The difference between this embodiment and embodiment 1 is that embodiment 1 has an endoscope channel 21 on the handle, while this embodiment does not have an endoscope channel 21, but instead has an endoscope 24, such as... Figure 12 As shown, this method uses endoscope 24 for single use, avoiding cross-infection. Everything else is the same as in Example 1.

Claims
1. A handle for an anchor conveying system, comprising: One handle housing; An energy storage slider (7) is installed in the handle housing in a way that allows it to slide back and forth. When the energy storage slider (7) moves backward to the energy storage position, it is connected to the handle housing through a locking mechanism, thus restricting its forward movement. It is also connected to the handle housing through an energy storage spring, thus giving it a tendency to move forward. When the locking mechanism fails, the energy storage slider (7) can move forward under the action of the energy storage spring. An energy storage component is provided in the handle housing in a way that allows it to slide back and forth. The energy storage component is provided with a push slider (6) that can slide up and down. The push slider (6) can be connected to or separated from the energy storage slider (7). When the push slider (6) is connected to the energy storage slider (7), the energy storage component can drive the energy storage slider (7) to move backward. When the push slider (6) separates from the energy storage slider (7), the energy storage component cannot drive the energy storage slider (7) to move; A shearing trigger rod (15) is installed in the handle housing in a way that allows it to slide up and down; Its features are, The locking mechanism includes a knob (10), which is rotatably mounted in the handle housing and given a rotational tendency by a spring. The knob (10) includes a hook post (10-1) for cooperating with the energy storage slider (7) and a drive post (10-2) for cooperating with the energy storage component. When the energy storage slider (7) moves backward to the energy storage position, the hook post (10-1) of the knob (10) can hook the energy storage slider (7) to lock it, thereby restricting the energy storage slider (7) from moving forward. When the energy storage component moves backward again, the energy storage component applies force to the drive post (10-2) on the knob (10), thereby causing the knob (10) to deflect until the hook post (10-1) on the knob (10) disengages from the energy storage slider (7) to unlock it. It also includes an unlocking component disposed inside the handle housing and capable of engaging with the push slider (6) on the energy storage component. The unlocking component has at least two position states: when the unlocking component is in the first position state, the push slider (6) can connect with the energy storage slider (7), thereby enabling the energy storage component to drive the energy storage slider (7) to move backward to the energy storage position; when the unlocking component is in the second position state, the unlocking component can force the push slider (6) to move downward and retract, thereby making the push slider no longer contact and connect with the energy storage slider (7), and the energy storage component cannot drive the energy storage slider (7) to move.
2. A handle for an anchor delivery system according to claim 1, wherein, It also includes a first motor (41) for driving the energy storage component to move back and forth and a second motor (42) for driving the shearing trigger rod (15) to move up and down. The unlocking component is connected to the shearing trigger rod (15) and controls the unlocking component to switch between multiple position states through the shearing trigger rod (15): when the shearing trigger rod is in the locked position, the unlocking component is in the first position state. When the shear trigger lever is in the unlocked position, the unlocking component is in the second position.
3. A handle for an anchor delivery system according to claim 2, wherein, The unlocking position, locking position and triggering position of the shearing trigger lever (15) are set from bottom to top, and a second sensor (42-1) for detecting the position status of the shearing trigger lever is installed inside the handle housing.
