Description

Technical Field

[0001] This invention relates to a prostate stapler device, belonging to the technical field of medical devices. Background Technology

[0002] In some men, the prostatic capsule surrounding the prostate may prevent further enlargement of the prostate. This can cause the internal areas of the prostate to compress the urethra. A common treatment method now involves implanting prostatic staples into the obstructed segment of the prostatic urethra through the natural cavity of the urethra. Similar to staples, these staples are driven into the enlarged prostatic tissue through the urethra. A special structure tightens the prostatic tissue, and the combined use of several staples can "bind" the prostate, widen the urethra, and, without removing tissue, "tighten" the enlarged prostatic gland in the urethra, relieving pressure on the urethra and restoring urethral patency.

[0003] Existing treatment tools include modules and handles configured to accommodate the modules. The handle and module combination pushes the bundle of staples for prostate staple manipulation. When inserting the bundle of staples into the prostate tissue, energy needs to be stored in advance through the handle to provide kinetic energy for the insertion of the bundle of staples. In actual surgery, the doctor stores energy in the bundle of staples through the handle before insertion, which increases the number of surgical steps. Moreover, storing energy requires a large force, which is more laborious. Furthermore, storing energy through the handle increases the internal structure of the handle, further increasing the cost of the surgical instrument. Summary of the Invention

[0004] The purpose of this invention is to provide a prostate stapler device that solves the problems of laborious surgical operation and increased cost of surgical instruments in the prior art.

[0005] The above-mentioned technical objective of this invention is mainly achieved through the following technical solution: a prostate stapler device, comprising a drive handle and a gate box pulsatingly connected to the drive handle. The drive handle is provided with a mounting groove that cooperates with and fixes the gate box. The gate box contains a needle slider pulsatingly connected to a puncture needle, a wire slider pulsatingly connected to the needle slider, and an energy storage slider for storing energy in the needle slider. The needle slider and the energy storage slider pass through the bottom of the mounting groove and are pulsatingly connected to the drive handle. A limiting block is provided at the moving end point of the needle slider. A limiting hook is provided on the side of the limiting block facing the energy storage slider to prevent the energy storage slider from automatically resetting. An energy storage spring is provided on the energy storage slider along the moving direction. The wall is equipped with a transmission block connected to the end of the energy storage spring. The side of the transmission block facing the energy storage slider is equipped with a blocking hook located at the bottom of the mounting groove and connected to the drive handle. The energy storage slider is pre-charged by the energy storage spring to the needle slider at the factory, eliminating the need for the doctor to charge the energy during the operation, reducing the number of surgical steps, and making the operation more labor-saving, convenient and easy to operate. The limiting block can lock the energy storage slider with the limiting hook when the energy storage is completed, preventing the energy storage slider from rebounding and maintaining the functional position of the energy storage slider. The blocking hook is set to limit the movement of the transmission block and prevent the transmission block from moving under the action of the energy storage spring in the energy storage state, so as to maintain a stable energy storage state.

[0006] Preferably, a limiting spring is provided on the side wall of the limiting block opposite to the direction of the limiting hook, and is connected to the bottom of the gate box. The top surface of the limiting hook is provided with an inclined groove that slopes toward the location of the limiting spring. A push rod is provided on the top of the needle slider, and the end of the push rod bends downward and extends into the inclined groove. The limiting spring provides power to the limiting block, so that the limiting block can maintain its limiting and blocking effect on the energy storage slider, and the limiting block can release its limiting and blocking effect on the energy storage slider at any time through the extension and contraction of the limiting spring. The inclined groove is provided so that when the needle slider is driven to move toward the limiting block by the force of the energy storage spring during the excitation operation, the needle slider can simultaneously drive the push rod to move into the inclined groove and lock the end of the push rod through the side wall of the inclined groove, preventing the needle slider from automatically returning to its original position.

[0007] Preferably, the line slider has a strip groove in the middle that runs along the moving direction of the needle slider, and a protrusion on the side of the line slider facing the transmission block. The bottom surface of the gate box has an elastic hook that engages with the protrusion and can float up and down. The end of the needle slider has a stop block that extends upward into the strip groove. A fixing post is provided on the side adjacent to the energy storage slider, and a tension spring is provided on the fixing post. A bundle of pins is connected to the rear end of the line slider, and the bundle of pins passes around the transmission block and connects to the end of the tension spring. The stop block of the needle slider is located in the strip groove, so that the needle slider can drive the line slider to move synchronously through the stop block when it is activated. The elastic hook can lock the protrusion after the activation operation, thereby limiting the movement of the line slider and preventing the line slider from retracting in the next operation.

[0008] Preferably, the drive handle includes an upper housing and a lower housing that are connected and fitted together. The lower housing has a gripping part on its side and a trigger on the adjacent side of the gripping part. The trigger includes a transmission section extending into the lower housing and a drive section located outside the lower housing and adjacent to the gripping part. The lower housing has a rotatable wheel. The end of the transmission section is rotatably connected to the lower housing and can drive the wheel to rotate intermittently. The trigger is connected to the lower housing through the transmission section and can rotate to drive the wheel to rotate with the trigger. The wheel can then drive the staples to be gradually driven into the prostate tissue through multiple rotations. The drive section of the trigger can synchronously drive the first transmission rack to move, so as to push the energy storage slider to achieve energy storage.

[0009] Preferably, the end face of the wheel is provided with a first arc-shaped protrusion for pushing the needle slider, a second arc-shaped protrusion for pushing the energy storage slider, and a protrusion for pushing the blocking hook. One end of the blocking hook is bent upward and abuts against the side wall of the transmission block, and the other end of the blocking hook is inclined downward and located on the rotation path of the protrusion. The bottom of the gate box is provided with a horizontally rotatable locking block, and the side wall of the upper housing is provided with a slot. One end of the locking block is located in the slot, and the other end of the locking block is located above the blocking hook. The bottom of the slot is provided with an inclined surface, and the side of the locking block is provided with a spring section that connects to the bottom of the gate box. The above-mentioned first arc-shaped protrusion and second arc-shaped protrusion allow the wheel to pass through the first arc-shaped protrusion when rotating. The arc-shaped and second arc-shaped protrusions respectively push the needle slider and the energy storage slider to move, thereby activating and driving the bundle pins. The protrusions can push the blocking hook when the wheel rotates, causing the blocking hook to disengage from the needle slider, thus activating the needle slider. The locking block can be locked onto the blocking hook by the action of the elastic section to prevent the blocking hook from disengaging, thereby achieving self-locking of the energy storage state and ensuring the stability of the energy storage state. The slot and bevel design allows the locking block to be moved by the bevel when the gate box is assembled on the drive handle, causing the other end of the locking block to disengage from the blocking hook, canceling the self-locking function, so as to facilitate subsequent activation operations.

[0010] Preferably, the center of the wheel's bottom surface is rotatably connected to the lower housing. A gear, rotatably connected to the lower housing and capable of driving the wheel to rotate in one direction, is located at the center of the wheel's bottom surface. An arc-shaped gear set is located on the side wall of the trigger's transmission section, near the side of the gear. The arc-shaped gear set partially meshes with the gear. A ratchet is located on the bottom surface of the wheel, abutting against the end face of the gear. A connecting arm extends from the side wall of the gear, capable of driving the ratchet to rotate in one direction. A helical gear ring is located on the bottom surface of the wheel corresponding to the circumference of the ratchet. A blocking strip, cooperating with the helical gear ring, restricts the unidirectional rotation of the wheel on the bottom surface of the lower housing. The aforementioned gear can be driven to rotate via the arc-shaped gear set in the transmission section. This allows the gear to drive the wheel to rotate synchronously, and the wheel to drive the first and second arc-shaped protrusions to rotate gradually, thus achieving structural transmission. The ratchet can be connected to the gear via a connecting arm, so that when the gear rotates, it can drive the ratchet to rotate in the same direction via the connecting arm. The ratchet can then drive the wheel to rotate synchronously in one direction. When the trigger is reset, the gear can disengage from the ratchet and rotate independently, while the wheel remains stationary through the cooperation of the helical gear ring and the blocking bar. This achieves the reset of the gear and stops the wheel from rotating. The gear can continue to drive the ratchet to rotate in the same direction, and then the intermittent rotation of the wheel is achieved through the reciprocating rotation of the trigger.

[0011] Preferably, the gate box contains an anchoring slider and a tangential slider that are spaced apart and movable relative to each other on the side corresponding to the limiting block. The anchoring slider and the tangential slider are connected by a return spring. A horizontally swinging limiting block is provided between the anchoring slider and the tangential slider. One end of the limiting block abuts against the side of the tangential slider facing the direction of movement, and the other end of the limiting block is located on the movement path of the anchoring slider. The anchoring slider and the tangential slider can anchor and tangentially cut the bolts, respectively. The return spring is provided to tighten the anchoring slider and the tangential slider, so that the rotation of the limiting block can drive the tangential slider to move under the action of the return spring. The anchoring slider can drive the tangential slider by rotating the limiting block.

[0012] Preferably, the anchoring slider has a self-locking block on its side, the middle of which is rotatably connected to the bottom of the gate box. The anchoring slider has a limiting groove on its side, one end of which abuts against the inner wall of the limiting groove, and the other end of which is close to a notch on the side wall of the gate box. A drive block that can rotate toward the self-locking block is located at the notch, with the top of the drive block inside the notch and close to the self-locking block. An arc-shaped strip fixed to the upper housing is provided on the side wall of the drive block, and an outward protrusion is provided on the side wall of the wheel. The bottom of the drive block is located on the travel path of the outward protrusion. The self-locking block can cooperate with the limiting groove to restrict the movement of the anchoring slider, thereby achieving self-locking of the anchoring slider. The drive block can push the self-locking block away from the limiting groove by the push of the outward protrusion on the wheel, thereby activating the anchoring slider. The arc-shaped strip can always act on the drive block, keeping the drive block separated from the self-locking block, so as to ensure that the outward protrusion can stably push the self-locking block to unlock the anchoring slider through the drive block.

[0013] Preferably, a cover is provided above the gate box, and a partition is provided between the gate box and the cover. A horizontally rotatable knob is provided in the middle of the cover. A limiting block is provided on the top surface of the partition on the side corresponding to the knob, which can restrict the movement of the energy storage slider. A driving part on the side wall of the knob can drive the limiting block to separate from the energy storage slider. The middle part of the limiting block is rotatably connected to the partition via a rotating shaft. One end of the limiting block can abut against the side of the energy storage slider facing the direction of movement of the energy storage slider, and the other end of the limiting block can abut against the driving part. The limiting block can restrict and lock the energy storage slider in the energy storage, preventing the energy storage slider from being accidentally activated due to accidental touch or collision. The limiting block is rotated via a rotating shaft, and the limiting block can restrict, lock, and unlock the energy storage slider by rotating, thus playing a transmission role for the knob.

[0014] Preferably, the knob has a downward-facing fixed shaft at its center, a downward-curving top block at its top, a protruding post on the top surface of the limiting block that protrudes upward from the top surface of the partition and is located on the movement trajectory of the top block, a vertically positioned paddle near the side wall of the knob on the side of the anchoring slider, and a paddle block on the side wall of the knob that can move the paddle. The fixed shaft allows the knob to rotate around it, facilitating the rotation of the drive unit. The top block limits the movement of the protruding post when locked, thereby restricting and locking the tangential slider and preventing accidental activation of the tangential slider during transportation. The paddle allows the protrusion on the side wall of the knob to move the paddle after the knob is rotated to the desired position when unlocking, providing a prompt to the operator that the unlocking was successful, facilitating further operation after successful unlocking.

[0015] Therefore, the present invention has the advantages of pre-storing energy at the factory, eliminating the need for doctors to store energy during surgery, reducing surgical procedures, making surgery more labor-saving, convenient and easy to operate, and also having the ability to self-lock the energy storage state to prevent accidental activation.

[0024] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] like Figure 1-3 As shown, a prostate stapler device includes a drive handle 1 and a gate box 2 pulverized to the drive handle 1. The drive handle 1 has a mounting groove 11 that cooperates with and fixes the gate box 2. The gate box 2 contains a needle slider 21 pulverized to a puncture needle, a wire slider 22 pulverized to the needle slider 21, and an energy storage slider 23 for storing energy in the needle slider 21. The needle slider 21 and the energy storage slider 23 pass through the bottom of the mounting groove 11 and are pulverized to the drive handle 1. A limiting block 24 is provided at the end point of the movement of the needle slider 21. A limiting hook 241 for preventing the energy storage slider 23 from automatically resetting is provided on the side of the limiting block 24 facing the energy storage slider 23. An energy storage spring 231 is provided on the energy storage slider 23 along the movement direction. A transmission block 211 connected to the end of the energy storage spring 231 is provided on the side wall of the needle slider 21. A blocking hook 12 located at the bottom of the mounting groove 11 and pulverized to the drive handle 1 is provided on the side of the transmission block 211 facing the energy storage slider 23.

[0026] The gate box is installed in the mounting slot of the drive handle, and the bottom of the gate box is connected to the puncture needle and the wire. The end of the wire is a bundled nail structure. Before operating the device, the energy storage slider is pre-charged at the factory, and the energy storage spring is in a stretched state. The top of the blocking hook abuts against the end face of the transmission block, blocking and limiting the transmission block. The edge of the side wall of the energy storage slider is locked on the limiting hook on the side of the limiting block, keeping the energy storage spring in a stretched state. When the limiting hook is released from blocking the transmission block by operating the drive handle, the top of the limiting hook moves downward away from the transmission block. The transmission block moves towards the energy storage slider under the action of the energy storage spring. When the transmission block moves, it drives the needle slider to move synchronously to realize the bundled nail activation. The needle slider drives the wire slider to move synchronously, thereby realizing the activation operation of the needle slider.

[0027] After the surgical procedure begins, the trigger is pulled first, causing the wheel to rotate ¼ turn. The transmission block, through the needle slider, moves the thread slider towards the energy storage slider to trigger the puncture needle to pierce the prostate wall. The trigger is then released, and the wheel stops. When the trigger is pulled a second time, the wheel rotates ¼ turn, and the first arc-shaped protrusion pushes the needle slider, causing it to move independently towards the thread slider. Simultaneously, the energy storage slider retracts, exposing the bundle of staples within the needle. One end of the bundle of staples remains at the puncture endpoint and extends. The trigger is then released, and the wheel stops. Then, the second... Pulling the trigger three times causes the wheel to rotate ¼ revolution. The second arc-shaped convex bar pushes the energy storage slider back, and the needle slider and the wire slider return to their original positions along with the energy storage slider. At this point, the puncture needle is completely withdrawn from the prostate tissue, while the bundle staples remain on the prostate tissue, and the bundle staple wires pull on the prostate sidewall through the extended blocking portion. Finally, pulling the trigger a fourth time causes the wheel to rotate ¼ revolution. The bundle staple wires are cut, and an anchor structure is attached at the cut point, thus cooperating with the end that previously pulled on the prostate sidewall, constricting the prostate sidewall, physically expanding the prostate passage, and completing the anchoring and cutting operation.

[0028] like Figure 2-3 As shown, a limiting spring 242 connected to the bottom of the gate box 2 is provided on the side wall of the limiting block 24 opposite to the direction of the limiting hook 241. A groove 243 inclined towards the position of the limiting spring 242 is provided on the top surface of the limiting hook 241. A push rod 212 is provided on the top of the needle slider 21. The end of the push rod 212 bends downward and extends into the groove 243. A strip groove 221 is provided in the middle of the line slider 22 along the moving direction of the needle slider 21. A protrusion 222 is provided on the side of the line slider 22 facing the transmission block 211. An elastic hook 223 that cooperates with the protrusion 222 and can float up and down is provided on the bottom surface of the gate box 2. A stop block 213 extending upward into the strip groove 221 is provided at the end of the needle slider 21. A fixing post 10 is provided on the side adjacent to the energy storage slider 23. A tension spring 101 is provided on the fixing post 10. A bundle of nails 214 is connected to the rear end of the line slider 22. The bundle of nails 214 passes around the transmission block 211 and connects to the end of the tension spring 101.

[0029] like Figure 2-3As shown, the drive handle 1 includes an upper housing 13 and a lower housing 14 that are connected and fitted together. A grip portion 141 is provided on the side of the lower housing 14, and a trigger 15 is provided adjacent to the grip portion 141. The trigger 15 includes a transmission section 152 extending into the lower housing 14 and a drive section 151 located outside the lower housing 14 and adjacent to the grip portion 141. A rotatable wheel 16 is provided inside the lower housing 14. The end of the transmission section 152 is rotatably connected to the lower housing 14 and can drive the wheel 16 to rotate intermittently. A first arc-shaped protrusion 161 for pushing the needle slider 21 is provided on the end face of the wheel 16. The second arc-shaped protrusion 162 of the energy storage slider 23 and the protrusion 163 for pushing the blocking hook 12 are pushed. One end of the blocking hook 12 is bent upward and abuts against the side wall of the transmission block 211. The other end of the blocking hook 12 is inclined downward and located on the rotation path of the protrusion 163. The bottom of the gate box 2 is provided with a horizontally rotatable locking block 25. The side wall of the upper housing 13 is provided with a slot 131. One end of the locking block 25 is located in the slot 131, and the other end of the locking block 25 is located above the blocking hook 12. The bottom of the slot 131 is provided with a slope 132. The side of the locking block 25 is provided with a spring section 251 that connects to the bottom of the gate box 2.

[0030] When the gate box is in the energy storage state, the energy storage spring is in the stretched state, while the transmission block is kept stationary by the blocking hook. The side edge of the energy storage slider is locked on the limiting hook of the limiting block. When the gate box is not assembled onto the drive handle, the locking block is locked on the top surface of one end of the blocking hook, and the outer end of the elastic section is connected to the bottom of the gate box. The elastic section pushes the locking block to remain on the top surface of the blocking hook through its own elastic force. When the gate box is assembled onto the drive handle, the other end of the locking block moves down from the slot to the inclined surface and then down the inclined surface to the bottom of the slot. During the process of the locking block moving down the inclined surface, the other end of the locking block is pushed by the inclined surface, causing the other end of the locking block to leave the blocking hook, thereby unlocking the blocking hook and allowing the protrusion to push the blocking hook.

[0031] At the start of the surgical procedure, the first pull of the trigger causes the wheel to rotate, driving the protrusion to rotate. During this rotation, the protrusion pushes the bottom of the blocking hook, causing the top of the blocking hook to disengage from the transmission block. The transmission block, under the action of the energy storage spring, moves rapidly toward the energy storage slider. The transmission block moves synchronously with the needle slider and the thread slider until the top rod of the needle slider is engaged in the inclined groove on the limiting block. At the same time, the protrusion on the side wall of the thread slider is engaged in the elastic hook, preventing the thread slider from retracting. Simultaneously, the tension spring is stretched, thereby tightening the staple wire. One end of the staple wire extends to the patient's prostate tissue, and the other end of the staple wire connects to the end of the tension spring. At this point, the activation operation is complete.

[0032] When the trigger is pulled for the second time, the wheel drives the first arc-shaped protrusion to rotate. During the rotation of the first arc-shaped protrusion, it pushes the needle slider to move in the direction of the line slider. During the movement of the needle slider, the push rod will push the limiting block to move in the direction of the limiting spring along the inclined groove. The limiting spring contracts, and the limiting block disengages from the energy storage slider when it moves. The energy storage slider then moves back with the needle slider. At this time, the line slider is still stuck on the elastic hook and remains stationary.

[0033] When the trigger is pulled for the third time, the wheel drives the second arc-shaped protrusion to rotate. During the rotation of the second arc-shaped protrusion, it pushes the energy storage slider towards the transmission block. During the movement of the energy storage slider, the transmission block is driven by the energy storage spring, which in turn moves the needle slider and the thread slider together. When the needle slider moves above the elastic hook, it presses the elastic hook downward, causing the elastic hook to bend downward and detach from the protrusion on the side wall of the thread slider. The thread slider can then move back along with the energy storage slider and the needle slider.

[0034] like Figure 4-6 As shown, the bottom center of the wheel 16 is rotatably connected to the lower housing 14. A gear 164 is provided at the bottom center of the wheel 16, which is rotatably connected to the lower housing 14 and can drive the wheel 16 to rotate in one direction. An arc-shaped gear set 1511 is provided on the side wall of the transmission section 152 of the trigger 15, which is close to the side of the gear 164. The arc-shaped gear set 1511 meshes with part of the gear 164. A ratchet 165 is provided on the bottom surface of the wheel 16, which abuts against the end face of the gear 164. A connecting arm 166 extends from the side wall of the gear 164, which can drive the ratchet 165 to rotate in one direction. A helical gear ring 167 is provided on the bottom surface of the wheel 16 corresponding to the circumference of the ratchet 165. A blocking strip 142 is provided on the bottom surface of the lower housing 14, which cooperates with the helical gear ring 167 to restrict the rotation of the wheel 16 in one direction.

[0035] When the trigger is pulled, the arc-shaped gear set on the transmission section drives the wheel. The arc-shaped gear set meshes with the gear on the bottom surface of the wheel. The arc-shaped gear set drives the wheel to rotate ¼ turn through the gear. When the arc-shaped gear set drives the gear to rotate, the gear drives the ratchet to rotate through the connecting arm. The ratchet drives the wheel to rotate, and the stop bar can jump along the helical gear ring. When the trigger is reset, the gear rotates synchronously in the opposite direction. The connecting arm loses the transmission to the ratchet. The ratchet stops rotating, and the wheel cannot rotate due to the block bar blocking the helical gear ring. When the trigger is pulled again, the gear can drive the ratchet again and drive the wheel to rotate ¼ turn again.

[0036] like Figure 2As shown, inside the gate box 2, on the side corresponding to the location of the limiting block 24, there are anchoring sliders 26 and tangential sliders 27 that are spaced apart and movable relative to each other. The anchoring sliders 26 and tangential sliders 27 are connected by a return spring 261. A horizontally swinging limiting block 28 is provided between the anchoring sliders 26 and tangential sliders 27. One end of the limiting block 28 abuts against the side of the tangential slider 27 facing the direction of movement, and the other end of the limiting block 28 is located on the movement path of the anchoring slider 26. A self-locking block 265 is provided on the side of the anchoring slider 26, and the middle of the self-locking block 265 is connected to the bottom of the gate box 2. The moving connection has a limiting groove 262 on the side of the anchoring slider 26. One end of the self-locking block 265 abuts against the inner wall of the limiting groove 262, and the other end of the self-locking block 265 is close to the notch 263 on the side wall of the gate box 2. The notch 263 is provided with a driving block 29 that can rotate toward the self-locking block 265. The top of the driving block 29 is located in the notch 263 and close to the self-locking block 265. The side wall of the driving block 29 is provided with an arc-shaped strip 291 fixed on the upper housing 13. The side wall of the wheel 16 is provided with an outward protrusion 168, and the bottom end of the driving block 29 is located on the travel path of the outward protrusion 168.

[0037] After the trigger is pulled for the last time, the wheel pushes the bottom of the drive block through the outward protrusion. The top of the drive block is thus driven to rotate toward the end of the self-locking block and push the end of the self-locking block. The other end of the self-locking block rotates and leaves the limiting groove. The anchoring slider is thus moved toward one end of the limiting block by the action of the return spring to achieve the anchoring operation. After the anchoring slider moves, it pushes one end of the limiting block. The other end of the limiting block rotates and leaves the tangent slider. The tangent slider is automatically moved a certain distance toward the anchoring slider by the action of the return spring to achieve the tangent operation. The arc strip is fixedly connected to the upper shell, so that the drive block can always be kept separated from the self-locking block.

[0038] like Figure 7-8As shown, a cover 3 is provided above the gate box 2, and a partition 31 is provided between the gate box 2 and the cover 3. A horizontally rotatable knob 32 is provided in the middle of the cover 3. A locking block 33 is provided on the top surface of the partition 31 on the side corresponding to the knob 32, which can restrict the movement of the energy storage slider 23. A drive part 321 on the side wall of the knob 32 can drive the locking block 33 to separate from the energy storage slider 23. The middle part of the locking block 33 is rotatably connected to the partition 31 through a rotating shaft 331. One end of the locking block 33 can be connected to the energy storage slider 23 facing the energy storage slider 23. One side of the moving direction abuts, and the other end of the locking block 33 can abut with the driving part 321. The knob 32 has a fixed shaft 34 set downward at its axis. The top of the knob 32 has a top block 322 that bends downward. The top surface of the limiting block 28 has a protruding post 281 that protrudes upward from the top surface of the partition 31 and is located on the moving trajectory of the top block 322. The side of the anchoring slider 26 is provided with a vertically set paddle 264 near the side wall of the knob 32. The side wall of the knob 32 has a paddle block 323 that can move the paddle 264. The aforementioned cover is fixed to the gate box, with a partition at the gate box opening. A knob is located in the middle of the cover and can be rotated. The energy-storing slider stores energy within the gate box. After energy storage, the end of the energy-storing slider and the protrusion protrude from the partition. One end of the locking block abuts against the side wall of the energy-storing slider in the direction of movement, restricting further movement of the energy-storing slider. The other end of the locking block is located on the movement trajectory of the drive unit, while the top block abuts against the side wall of the protrusion, restricting the rotation of the limit block. When unlocking is required, the knob is rotated. The rotation of the knob drives the drive unit to push one end of the locking block, causing the other end of the locking block to leave the energy-storing slider, thereby releasing the lock on the energy-storing slider. The top block also leaves the protrusion, releasing the lock on the limit block.
