DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-13 As shown, a circumcision advancement mechanism of a circumcision suture device comprises a sheath 1 and a sliding member 3 slidably arranged therein, a firing handle 2 is hingedly arranged on the sheath 1, a ratchet 7 rotatably arranged on the sheath 1 is sleeved on the outer wall of a hinge shaft 27 arranged on the firing handle 2, and a torsion spring member 72 is arranged between the ratchet 7 and the hinge shaft 27, a pressure rod 5 slidably arranged on the sheath 1 is located on the downward swing path of the firing handle 2, and a locking rod 53 fixedly installed on the pressure rod 5 is inserted into the tooth opening of the ratchet 7 in a default state;

[0037] When the firing handle 2 swings down and approaches the sheath 1, the tooth portion 21 provided at the end of the firing handle 2 and the row of teeth 31 provided on the outer wall of the sliding member 3 are meshed, and the torsion spring member 72 is deformed to store force;

[0038] When the firing handle 2 is pressed down on the pressure rod 5, the locking rod 53 slides along with the pressure rod 5 to disengage from the teeth of the ratchet 7, and the torsion spring 72 releases the stored force.

[0039] Specifically, the outer wall of the sheath 1 is provided with a slot 12, and the firing handle 2 is hingedly arranged on the inner wall of the slot 12 through a hinge shaft 27 fixedly installed at its first end, and the tooth portion 21 is arranged at the first end of the firing handle 2 and is coaxially arranged with the hinge shaft 27, and the row of teeth 31 arranged on the outer wall of the sliding member 3 is meshed with the tooth portion 21, and the sheath 1 is threadedly provided with a glans cover rod 33, and the sliding member 3 is sleeved on the glans cover rod 33. The ratchet 7 is rotatably provided in the function box 13 provided on the sheath 1, and the first end of the sliding member 3 is fixedly provided with a sewing cover ring 32.

[0040] Furthermore, the two ends of the torsion spring member 72 are respectively fixedly mounted on the ratchet 7 and the hinge shaft 27, a function box 13 is fixedly mounted on the sheath 1, and the ratchet 7 is movably arranged in the function box 13, a cross bar 51 fixedly mounted on the pressure rod 5 is movably arranged in the function box 13, and a locking rod 53 is fixedly mounted on the cross bar 51, an embedded spring 52 is fixedly mounted on the cross bar 51, and a first end of the embedded spring 52 is fixedly mounted on the inner wall of the function box 13, and the cross bar 51 is pushed by the embedded spring 52 so that the top end of the locking rod 53 is inserted into the tooth mouth of the ratchet 7.

[0041] When circumcision is required, the patient's glans is placed on the end of the glans cover rod 33, and then the patient's foreskin is wrapped on the outer wall of the glans cover rod 33 and fixed with medical binding wire, and then the glans cover rod 33 is inserted into the sheath 1, and the nut block at one end of the sheath 1 relative to the suture cover ring 32 is threadedly assembled on the glans cover rod 33 to limit the glans cover rod 33, and then the user holds the sheath 1 and the firing handle 2 with one hand, and the other hand can support the patient's penis for a certain positioning, and the user's palm is used to exert force to make the firing handle 2 flip over and approach the sheath 1. At this time, because the top end of the locking rod 53 is inserted into the tooth mouth of the ratchet 7, the torsion spring member 72 is deformed and accumulates force during the flipping of the firing handle 2. At the same time, because the firing handle 2 flips over and approaches the sheath 1, the tooth portion 21 and the row of teeth 31 arranged on the outer wall of the sliding member 3 are engaged, thereby driving The sliding member 3 slides in the sheath 1, and the sliding of the sliding member 3 pushes the suture cover ring 32 to approach the glans cover rod 33, so as to perform the circumcision operation by using the suture nail bin and the circumcision knife provided on the suture cover ring 32, and when the suture cover ring 32 approaches the glans cover rod 33, if the glans cover rod 33 and the glans are offset to a certain extent, the palm of the user holding the sheath 1 and the firing handle 2 is relaxed, and at this time, the torsion spring member 72 releases the stored force to drive the firing handle 2 to flip and move away from the sheath 1, and at this time, due to the flipping of the firing handle 2, the tooth portion 21 is meshed with the row of teeth 31 again to drive the sliding member 3 to slide, and the suture cover ring 32 slides away from the glans cover rod 33 with the sliding member 3, so as to facilitate the user to better observe the position of the glans in the glans cover at the end of the glans cover rod 33, so as to adjust the position of the glans cover rod 33 on the glans, so as to make the circumcision incision more accurate. Compared with the traditional manual holding firing handle 2 retreat, it is more flexible and convenient to use and adjust.

[0042] Furthermore, after the positions of the glans cover and the glans at the end of the glans cover rod 33 are accurately adjusted, the firing handle 2 is pressed again to approach the sheath 1 so that the suture staple cartridge and the circumcision knife provided on the suture cover ring 32 can perform the circumcision operation. When the circumcision is about to be performed, as the firing handle 2 is flipped, the firing handle 2 squeezes the pressure rod 5 and causes the pressure rod 5 to slide, and then the locking rod 53 slides with the pressure rod 5 to disengage from the tooth mouth of the ratchet 7. At this time, the torsion spring member 72 completely releases the stored force to remove the resistance to the firing handle 2 flipping down close to the sheath 1, so that the force pressing the firing handle 2 can act more on the sliding member 3, thereby transmitting the force of the suture cover ring 32 to make more force act on the suture staple cartridge and the circumcision knife provided on the suture cover ring 32 to perform the circumcision and suturing operations, thereby enhancing the circumcision force of the circumcision knife and the pushing force of the suture staples in the suture staple cartridge.

[0043] In the above technical scheme, the torsion spring member 72 is deformed and stored force during the process of pressing the firing handle 2 to flip it close to the sheath 1, so that when the firing handle 2 is released, the torsion spring member 72 releases the stored force to drive the firing handle 2 to flip up, and in the process of flipping the firing handle 2, the tooth portion 21 and the row of teeth 31 arranged on the outer wall of the sliding member 3 are engaged to realize the operation of advancing and retracting the knife, thereby facilitating a certain adjustment of the cutting position. Secondly, after the adjustment is completed, the firing handle 2 is flipped down and pressed on the pressure rod 5 to disengage the locking rod 53 from the tooth mouth of the ratchet 7. At this time, the torsion spring member 72 releases the stored force to remove the resistance to the flipping of the firing handle 2, so that the user's pressing force is more used for cutting and suturing operations.

[0044] As an embodiment further provided by the present invention, the firing handle 2 is movably arranged between the arc-shaped baffles 11 symmetrically arranged on the outer wall of the sheath 1, one of the arc-shaped baffles 11 is provided with a plurality of positioning grooves 15, and the positioning rods 24 slidably arranged on the firing handle 2 are movably arranged in the plurality of positioning grooves 15, respectively, and a force storage spring 25 is fixedly installed on the positioning rods 24.

[0045] Specifically, the first end of the positioning rod 24 is provided with a curved surface 28, and the two ends of the storage spring 25 are respectively fixedly mounted on the positioning rod 24 and the firing handle 2. The storage spring 25 is used to push the positioning rod 24 so that the first end of the positioning rod 24 is stuck in the positioning groove 15.

[0046] Furthermore, in the process of pressing the firing handle 2 to flip it close to the sheath 1, the torsion spring member 72 deforms and accumulates force. At the same time, as the firing handle 2 flips, the curved surface portions 28 on the positioning rod 24 are squeezed against the notches of the positioning groove 15 respectively, thereby squeezing the positioning rod 24 to slide and disengage from the positioning groove 15. As the firing handle 2 flips toward the sheath 1, the first end of the positioning rod 24 is again inserted into another adjacent positioning groove 15. Then, when the flipping is stopped and the firing handle 2 is released, the torsion spring member 72 releases the accumulated force and the positioning groove 15 limits the positioning rod 24 so that the angle between the firing handle 2 and the sheath 1 is fixed. Therefore, in the process of the firing handle 2 flipping close to the sheath 1, the positioning rod 24 switches between multiple positioning grooves 15, so that the angle between the firing handle 2 and the sheath 1 can be fixed when the firing handle 2 stops flipping. Therefore, the angle of the firing handle 2 can be locked at any time, and the angle and position of the circumcision knife and the patient's foreskin can be observed in time to facilitate timely adjustment, thereby greatly improving the accuracy of circumcision.

[0047] As another embodiment provided by the present invention, an unlocking block 22 is slidably provided on the side of the firing handle 2, and a connecting rod 23 is fixedly installed between the unlocking block 22 and the positioning rod 24, and the unlocking block 22 slides to disengage the positioning rod 24 from the positioning groove 15.

[0048] Specifically, in order to facilitate the process of pressing the firing handle 2 to flip close to the sheath 1, the positioning rod 24 is released from the positioning groove 15 to unlock and adjust the position of the circumcision knife relative to the glans foreskin, such as Figure 1 and Fig.10 As shown, the user's four fingers except the thumb are attached to the bottom outer wall of the sheath 1, and the user's palm is attached to and pressed down on the firing handle 2, so that when the four fingers and the palm exert force, the firing handle 2 is flipped close to the sheath 1, and the positioning rod 24 is flipped with the firing handle 2 to move between the multiple positioning grooves 15. At the same time, as the firing handle 2 is flipped, the torsion spring member 72 is deformed and accumulates force. When it is necessary to lift and adjust the position of the firing handle 2, the user's thumb presses the unlocking block 22, so that when the unlocking block 22 slides, the positioning rod 24 is driven to slide and disengage from the positioning groove 15. At this time, as the torsion spring member 72 releases the accumulated force and the user's palm relaxes, the firing handle 2 is lifted relative to the sheath 1, and at the same time, the tooth portion 21 engages with the row of teeth 31 again to drive the sliding member 3 to slide, and the sewing cover ring 32 slides away from the glans cover rod 33 with the sliding member 3, so as to facilitate the user to better observe the position of the glans in the glans cover at the end of the glans cover rod 33, so as to adjust the position of the glans cover rod 33 on the glans.

[0049] Furthermore, by operating the sheath 1 and pressing the unlocking block 22 with one hand, the user's other hand can always maintain the state of supporting the patient's penis, thereby adjusting the position of the ring incision while reducing the problem of displacement of the ring incision position caused by lack of support for the patient's penis.

[0050] As another embodiment provided by the present invention, a main gear 71 is fixedly installed on the outer wall of the ratchet 7 along one side of the axis, and a rack 61 is slidably arranged in the function box 13 arranged on one side of the sheath 1, and the firing handle 2 squeezes the pressure rod 5 to make the locking rod 53 disengage from the tooth mouth of the ratchet 7. After the torsion spring 72 releases the stored force, the rack 61 slides and engages with the main gear 71 to allow the torsion spring 72 to store force.

[0051] Specifically, the user holds the sheath 1 and presses the firing handle 2 to flip it close to the sheath 1. At this time, the top end of the locking rod 53 is inserted into the tooth mouth of the ratchet 7, so that the torsion spring 72 is deformed and accumulates force during the flipping of the firing handle 2, and the tooth portion 21 on the firing handle 2 and the row of teeth 31 set on the outer wall of the sliding member 3 are engaged, thereby driving the sliding member 3 to slide in the sheath 1. Due to the sliding of the sliding member 3, the suture cover ring 32 is pushed close to the glans cover rod 33, so that the suture nail magazine and the circumcision knife set on the suture cover ring 32 are used to perform the circumcision operation. When the circumcision is about to be performed, as the firing handle 2 is flipped, the firing handle 2 squeezes the pressure rod 5 and causes the pressure rod 5 to slide, and then the locking rod 53 slides with the pressure rod 5 to disengage from the teeth of the ratchet 7. At this time, the torsion spring member 72 completely releases the stored force to remove the resistance to the firing handle 2 turning down close to the sheath 1, so that the force pressing the firing handle 2 acts more on the sliding member 3, thereby transmitting the force of the suture cover ring 32 to make more force act on the suture staple magazine and the circumcision knife arranged on the suture cover ring 32.

[0052] Furthermore, when the torsion spring member 72 releases the stored force, the rack 61 slides and meshes with the main gear 71. At this time, the rack 61 is used to drive the main gear 71 to rotate. At this time, the rotation of the main gear 71 causes the torsion spring member 72 to store force again, and the stored force acts on the hinge shaft 27 on the firing handle 2. At this time, the firing handle 2 is subjected to the stored force of the torsion spring member 72 to flip toward the side of the sheath 1. Therefore, when the user's hand presses the firing handle 2 to generate downward pressure on the firing handle 2, the rack 61 and the main gear 71 are meshed to make the force of the rack 61 act on the firing handle 2 along the torsion spring member 72 and the hinge shaft 27, thereby increasing the force of the firing handle 2 flipping toward the side of the sheath 1, thereby increasing the circumcision force of the circumcision knife on the foreskin.

[0053] The rack 61 may slide by being pushed by an electric push rod, by a motor in conjunction with a gear, or by any other method known to those skilled in the art to drive the rack 61 to slide.

[0054] As another embodiment provided by the present invention, the insertion rod 54 fixedly mounted on the pressure rod 5 is slidably disposed in the socket 63 opened on the rack 61, and the insertion rod 54 is separated from the socket 63 after the locking rod 53 is separated from the tooth opening of the ratchet 7.

[0055] Specifically, the insertion rod 54 is fixedly installed on the cross bar 51 , and in the default state, the embedded spring 52 pushes the cross bar 51 so that the top end of the locking rod 53 is inserted into the tooth opening of the ratchet 7 , and the insertion rod 54 is inserted into the socket 63 opened on the rack 61 .

[0056] Furthermore, after the user holds the sheath 1, he presses the firing handle 2 to flip it close to the sheath 1. At this time, because the top end of the locking rod 53 is inserted into the tooth mouth of the ratchet 7, the torsion spring 72 deforms and accumulates force during the flipping of the firing handle 2. The tooth portion 21 on the firing handle 2 and the row of teeth 31 arranged on the outer wall of the sliding member 3 are engaged, thereby driving the sliding member 3 to slide in the sheath 1. Due to the sliding of the sliding member 3, the suture cover ring 32 is pushed close to the glans cover rod 33, so that the suture nail magazine and the circumcision knife arranged on the suture cover ring 32 are used to perform the circumcision operation. When the circumcision is about to be made, as the firing handle 2 is flipped, the firing handle 2 squeezes the pressure rod 5 and makes the pressure rod 5 slide, and then the locking rod 53 slides with the pressure rod 5 to disengage from the teeth of the ratchet 7. At this time, the torsion spring member 72 completely releases the stored force to remove the resistance to the firing handle 2 flipping down close to the sheath 1, and then as the pressure rod 5 slides, the insertion rod 54 disengages from the socket 63. At this time, the rack 61 is unlocked and can slide, and then the rack 61 slides and meshes with the main gear 71. At this time, the rack 61 is used to drive the main gear 71 to rotate. At this time, the rotation of the main gear 71 makes the torsion spring member 72 store force again, and the stored force acts on the hinge shaft 27 on the firing handle 2. At this time, the firing handle 2 is subjected to the stored force of the torsion spring member 72 to flip toward the side of the sheath 1.

[0057] Furthermore, in order to achieve the sliding of the rack 61 and the engagement of the main gear 71 when the insertion rod 54 is disengaged from the socket 63, an elastic member can be provided on the side of the rack 61 opposite to the main gear 71. The elastic member can be a spring; it can also be an airbag; or it can be any elastic member known to those skilled in the art.

[0058] The elastic members are in a force storage state in the default state, and when the insertion rod 54 is disengaged from the socket 63, the elastic members release the stored force to push the rack 61 to slide, so that the rack 61 slides and engages with the main gear 71, thereby achieving the effect of automatic triggering and sliding of the rack 61, so that a certain force is applied when the user presses the firing handle 2, thereby increasing the force for flipping the firing handle 2 toward the side of the sheath 1, thereby increasing the cutting force of the circumcision knife.

[0059] As the optimal embodiment provided by the present invention, the first piston plate 6 fixedly mounted on the rack 61 is slidably disposed in the function box 13, and the second piston plate 45 slidably disposed in the function box 13 slides to compress the cavity between the first piston plate 6 and the second piston plate 45.

[0060] Specifically, in the default state, the embedded spring 52 pushes the cross bar 51 so that the top end of the locking rod 53 is inserted into the tooth opening of the ratchet 7, and the insertion rod 54 is inserted into the insertion opening 63 opened on the rack 61, thereby locking the rotation of the ratchet 7 and the sliding of the rack 61. The second piston plate 45 is driven to slide toward the first piston plate 6 to compress the cavity between the first piston plate 6 and the second piston plate 45.

[0061] Then, when the firing handle 2 is turned toward the side of the sheath 1, the torsion spring 72 is deformed and stores force, and then as the firing handle 2 is turned, the firing handle 2 squeezes the pressure rod 5 and causes the pressure rod 5 to slide, and the locking rod 53 slides with the pressure rod 5 to disengage from the teeth of the ratchet 7. At this time, the torsion spring 72 is unlocked and completely releases the stored force to remove the resistance to the firing handle 2 being turned down close to the sheath 1, and then slides with the pressure rod 5 to disengage the insertion rod 54 from the socket 63. At this time, the rack 61 is unlocked, and the first piston plate 6 and the second The cavity between the piston plates 45 is in a compressed state. When the rack 61 is unlocked, the first piston plate 6 drives the rack 61 to slide quickly close to the main gear 71, and then the rack 61 slides and meshes with the main gear 71. At this time, the rack 61 is used to drive the main gear 71 to rotate. At this time, the rotation of the main gear 71 causes the torsion spring 72 to accumulate force again, and the accumulated force acts on the hinge shaft 27 on the firing handle 2. At this time, the firing handle 2 is subjected to the accumulated force of the torsion spring 72 to be flipped toward the side of the sheath 1.

[0062] The second piston plate 45 may slide by rotating a screw rod on the function box 13, and then the screw rod pushes the second piston plate 45 to slide close to the first piston plate 6; or the second piston plate 45 may slide by being pushed by an electric push rod; or any other method known to those skilled in the art to drive the second piston plate 45 to slide.

[0063] As another embodiment provided by the present invention, the screw 44 fixedly mounted on the second piston plate 45 and the nut member 43 rotatably arranged in the function box 13 are threadedly rotated, and the worm wheel 42 fixedly mounted on the outer wall of the nut member 43 and the worm 41 rotatably arranged on the function box 13 are meshed.

[0064] Specifically, one end of the worm 41 extends out of the outer wall of the function box 13, and a knob 4 is fixedly installed on one end of the worm 41. Before using the sleeve 1, the knob 4 is turned to make the worm 41 and the worm wheel 42 engage, and then the worm wheel 42 drives the nut 43 to rotate, and the nut 43 and the screw rod 44 are threadedly rotated, so that the screw rod 44 moves and drives the second piston plate 45 to slide close to the first piston plate 6. At this time, the cavity between the first piston plate 6 and the second piston plate 45 is in a compressed state.

[0065] The engagement of the worm 41 and the worm wheel 42 can lock the rotation of the nut member 43, and the use of a driving source is omitted.

[0066] As another embodiment provided by the present invention, an outer wall of the function box 13 is provided with an exhaust hole 16 located on the side of the first piston plate 6 opposite to the second piston plate 45, and a spring member 55 fixedly installed in the function box 13 is located on the moving path of a poking rod 62 fixedly installed on the first piston plate 6, and the poking rod 62 slides to compress the spring member 55 to deform and store force.

[0067] Specifically, a force-bearing plate 56 is slidably disposed in the function box 13 , and the force-bearing plate 56 is located on one side of the poking rod 62 , and two ends of the spring member 55 are fixedly mounted on the force-bearing plate 56 and the inner wall of the function box 13 , respectively.

[0068] Furthermore, in the default state, the embedded spring 52 pushes the cross bar 51 so that the top end of the locking rod 53 is inserted into the tooth opening of the ratchet 7, and the insertion rod 54 is inserted into the insertion hole 63 provided on the rack 61, thereby locking the rotation of the ratchet 7 and the sliding of the rack 61. When in use, the knob 4 is turned to mesh the worm 41 and the worm wheel 42, and then the worm wheel 42 drives the nut 43 to rotate, and the nut 43 and the screw rod 44 are threadedly rotated, so that the screw rod 44 moves and drives the second piston plate 45 to slide close to the first piston plate 6, and at this time, the cavity between the first piston plate 6 and the second piston plate 45 is in a compressed state.

[0069] Furthermore, after the user holds the sheath 1, he presses the firing handle 2 to flip it close to the sheath 1. At this time, the torsion spring 72 deforms and accumulates force during the flipping of the firing handle 2, and the tooth portion 21 on the firing handle 2 engages with the row of teeth 31 provided on the outer wall of the sliding member 3, thereby driving the sliding member 3 to slide in the sheath 1. Due to the sliding of the sliding member 3, the suture cover ring 32 is pushed close to the glans cover rod 33, so that the suture nail magazine provided on the suture cover ring 32 and the circumcision knife are used to perform the circumcision operation. When the circumcision is about to take place, as the firing handle 2 is flipped, the firing handle 2 squeezes the pressure rod 5 and causes the pressure rod 5 to slide, and then the locking rod 53 slides with the pressure rod 5 to disengage from the teeth of the ratchet 7. At this time, the torsion spring member 72 completely releases the stored force to remove the resistance to the firing handle 2 flipping down close to the sheath 1, and then as the pressure rod 5 slides, the insertion rod 54 disengages from the socket 63 and unlocks the rack 61. Since the cavity between the first piston plate 6 and the second piston plate 45 is in a compressed state, the compressed cavity expands at this time, and the first piston plate 6 drives the rack 61 to slide quickly close to the main gear 71, and then the rack 61 slides and meshes with the main gear 71. At this time, the rack 61 is used to drive the main gear 71 to rotate. At this time, due to the rotation of the main gear 71, the torsion spring member 72 accumulates force again, and the stored force acts on the hinge shaft 27 on the firing handle 2. At this time, the firing handle 2 is subjected to the stored force of the torsion spring member 72 to flip toward the side of the sheath 1.

[0070] Furthermore, during the sliding of the first piston plate 6, the poking rod 62 on the first piston plate 6 slides to push the force plate 56, and then the force plate 56 compresses the spring member 55 to deform and store force. At the same time, the first piston plate 6 slides so that the exhaust hole 16 is located between the first piston plate 6 and the second piston plate 45. At this time, the compressed gas between the first piston plate 6 and the second piston plate 45 is discharged along the exhaust hole 16, thereby reducing the pressure between the first piston plate 6 and the second piston plate 45. Due to the reduction in pressure, the squeezing force of the poking rod 62 on the force plate 56 gradually decreases, and as the spring member 55 releases the stored force, the rack 61 engages with the main gear 71 again, and causes the torsion spring member 72 to gradually release the stored force, thereby releasing the force on the firing handle 2.

[0071] The rack 61 is moved to realize the turning force of the firing handle 2 when it is close to the sheath 1, so as to increase the force on the ring cutter. The rack 61 is reset to release the force on the firing handle 2, so as to facilitate the subsequent operation of turning up and resetting the firing handle 2.

[0072] As another embodiment further provided by the present invention, a tooth block 65 arranged in a linear array is hingedly provided on the poking rod 62, and a return spring 64 is fixedly installed on the tooth block 65. The first piston plate 6 slides to make the tooth block 65 engage with the ratchet 7 in turn, and then the rack 61 and the main gear 71 engage. When the spring member 55 releases the stored force, it pushes the poking rod 62 and makes the tooth block 65 engage with the ratchet 7 in turn.

[0073] Specifically, a magnet block 8 is fixedly mounted on the sheath 1 , and a first end of the return spring 64 is fixedly mounted on the poking rod 62 .

[0074] Furthermore, when circumcision is required, the knob 4 is turned to mesh the worm 41 and the worm wheel 42, and then the worm wheel 42 drives the nut 43 to rotate, and the nut 43 and the screw rod 44 are threadedly rotated, so that the screw rod 44 moves and drives the second piston plate 45 to slide close to the first piston plate 6, and the cavity between the first piston plate 6 and the second piston plate 45 is in a compressed state. Then, after the patient's glans is placed on the end of the glans cover rod 33 and the patient's foreskin is wrapped on the outer wall of the glans cover rod 33, the glans cover rod 33 is installed on the sheath 1.

[0075] Then, the user holds the sheath 1 and the firing handle 2 with one hand and supports the patient's penis with the other hand, and then holds the sheath 1 and the firing handle 2 tightly to flip the firing handle 2 to the side of the sheath 1. At this time, the embedded spring 52 pushes the cross bar 51 so that the top end of the locking rod 53 is inserted into the tooth mouth of the ratchet 7, and the insertion rod 54 is inserted into the socket 63 opened on the rack 61, thereby locking the rotation of the ratchet 7 and the sliding of the rack 61. Therefore, when the firing handle 2 is flipped toward the sheath 1, the torsion spring member 72 is deformed and stores force, and at the same time, the positioning rod 24 is flipped along with the firing handle 2 to move between the multiple positioning grooves 15. When it is necessary to lift the firing handle 2 to adjust the position of the foreskin at the circumcision knife incision, the unlocking block 22 is pressed by the user's thumb, thereby driving the positioning rod 24 to slide and disengage from the positioning groove 15 when the unlocking block 22 slides. At this time, as the torsion spring member 72 releases the stored force and the user's palm relaxes, the firing handle 2 is lifted relative to the sheath 1, and at the same time, the tooth portion 21 engages with the row of teeth 31 again to drive the sliding member 3 to slide, and the suture cover ring 32 slides away from the glans cover rod 33 along with the sliding member 3, thereby facilitating the user to better observe the position of the glans in the glans cover at the end of the glans cover rod 33, so as to facilitate the adjustment of the position of the glans cover rod 33 on the glans.

[0076] When circumcision is required, the sheath 1 and the firing handle 2 are gripped again to flip the firing handle 2 to the side of the sheath 1, and then the firing handle 2 squeezes the pressure rod 5 and makes the pressure rod 5 slide and adsorbed on the magnet block 8, and then the locking rod 53 slides with the pressure rod 5 to disengage from the teeth of the ratchet 7. At this time, the torsion spring member 72 completely releases the stored force to remove the resistance to the firing handle 2 flipping down close to the sheath 1, and then slides with the pressure rod 5 to disengage the insertion rod 54 from the socket 63 and unlock the rack 61. Since the cavity between the first piston plate 6 and the second piston plate 45 is in a compressed state, the compressed cavity expands at this time, and the first piston plate 6 drives the poking rod 62 to slide to push the force plate 56, and then the force plate 56 compresses the spring member 55 to deform and store force. During the sliding process of the first piston plate 6, the multiple tooth blocks 65 on the poking rod 62 are sequentially matched with the ratchet 7 to block and disassemble, and then the tooth block 65 compresses the reset spring 64 during the block and disassembly. When the tooth block 65 passes over the ratchet 7, the reset spring 64 resets to push the tooth block 65. After the multiple tooth blocks 65 pass over the ratchet 7 respectively, the rack 61 and the main gear 71 are meshed. At this time, the rack 61 is used to drive the main gear 71 to rotate. At this time, the rotation of the main gear 71 causes the torsion spring member 72 to accumulate force again, and the accumulated force acts on the hinge shaft 27 on the firing handle 2. At this time, the firing handle 2 is subjected to the accumulated force of the torsion spring member 72 to flip to the side of the sheath 1. The cutting force of the ring cutter is enhanced by the meshing of the rack 61 and the main gear 71.

[0077] Furthermore, as the first piston plate 6 slides so that the exhaust hole 16 is located between the first piston plate 6 and the second piston plate 45, the compressed gas between the first piston plate 6 and the second piston plate 45 is discharged along the exhaust hole 16, thereby reducing the pressure between the first piston plate 6 and the second piston plate 45. Due to the reduction in pressure, the squeezing force of the poking rod 62 on the force plate 56 gradually decreases, and the spring member 55 releases the stored force. At this time, the rack 61 engages with the main gear 71 again, and the torsion spring member 72 gradually releases the stored force, thereby releasing the force on the firing handle 2. Then, as the spring member 55 continues to release the stored force, the multiple tooth blocks 65 on the poking rod 62 respectively mesh with the ratchet 7, thereby causing the ratchet 7 to rotate. At this time, the rotation of the ratchet 7 causes its rotational force to act on the hinge shaft 27 again through the torsion spring member 72, so that the firing handle 2 is subjected to the force to flip up and away from the sheath 1. At this time, by slowly loosening the sheath 1 and the firing handle 2, the torsion spring member 72 releases the force to drive the firing handle 2 to flip up and away from the sheath 1, thereby facilitating the operation of moving the circumcision knife away from the incision port and eliminating the operation of manually holding the firing handle 2 to flip it up.

[0078] As an optimal embodiment further provided by the present invention, an elastic sheet 26 that is blocked and stores force by the positioning rod 24 is fixedly installed on the firing handle 2, and the curved portion 28 set at the first end of the positioning rod 24 and the block 14 set on the sheath 1 are blocked and cooperated, and the positioning rod 24 slides to release the blocking of the elastic sheet 26, and the elastic sheet 26 releases the stored force to fit the first end of the positioning rod 24.

[0079] Specifically, in a default state, the positioning rod 24 blocks the elastic sheet 26 for storing force, and a first end of the elastic sheet 26 is fixedly mounted on the firing handle 2 .

[0080] Furthermore, in order to prevent the firing handle 2 from being affected by the positioning rod 24 being stuck in the positioning groove 15 when it is turned up and away from the sheath 1. Fig.11 and Fig.12 As shown, when the firing handle 2 flips toward the side of the sheath 1 and the firing handle 2 begins to squeeze the pressure rod 5, the curved surface 28 on the positioning rod 24 is blocked and pushed by the block 14 to drive the positioning rod 24 to slide out of the positioning groove 15, and then the positioning rod 24 slides to release the obstruction of the elastic sheet 26. At this time, the elastic sheet 26 releases the stored force to move its second end to the first end of the positioning rod 24, and then the elastic sheet 26 is used to block the positioning rod 24 to prevent it from sliding and getting engaged in the positioning groove 15 again, affecting the firing handle 2 from flipping up and away from the sheath 1.

[0081] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
