[0070] Please refer to Figures 1 to 3The foreskin stapler 100 includes a housing 10, an anvil 20, a cutting structure 30, a nail pushing assembly 40, a nail magazine assembly 70, a firing assembly 60 and an adjusting member 80. The anvil 20 is detachably connected to the housing 10, and includes a glans seat 210 and a screw rod 220. The screw rod 220 is connected to the glans seat 210, and the glans is placed in the accommodating cavity 211 of the glans seat 210. The foreskin to be cut is stretched proximally and covered on the glans seat 210 and fixed to the screw rod 220.

[0071] The proximal end involved in the embodiment of the present application is the end close to the operator holding the firing assembly 60, and the distal end is the end away from the operator holding the firing assembly 60. The firing assembly 60 includes a firing handle 610 and a firing torsion spring. The operator holds the firing handle 610 and rotates it relative to the housing 10 so that the firing handle 610 can act on the nail pushing assembly 40 and / or the cutting structure 30. After the rotation firing is completed, the firing handle 610 can be reset under the action of the firing torsion spring.

[0072] The staple cartridge assembly 70 includes a staple cartridge 710 and a staple cartridge sleeve 720 of an annular structure. The staple cartridge 710 is mounted on the staple cartridge sleeve 720. The staple cartridge 710 contains suture staples. The staple pusher assembly 40 includes a staple pusher seat 410 and a plurality of staple pusher blocks 420. The plurality of staple pusher blocks 420 are connected to the distal end of the staple pusher seat 410 and are circumferentially distributed around the axis thereof. The plurality of staple pusher blocks 420 are opposite to the positions of the suture staples in the staple cartridge 710. Under the action of the firing assembly 60, the staple pusher blocks 420 push the suture staples to act on the foreskin to be cut, thereby achieving suture.

[0073] The cutting structure 30 includes a cutting assembly 310 , and the cutting assembly 310 includes a circular cutting knife 311 and a knife holder 312 . The circular cutting knife 311 of the annular structure is connected to the distal end of the knife holder 312 , and the circular cutting knife 311 can cut the foreskin under the action of the firing assembly 60 .

[0074] The adjusting member 80 has an internal thread, and the proximal end of the screw rod 220 has an external thread matching the internal thread. Rotating the adjusting member 80 can adjust the relative position of the screw rod 220 and the shell 10, that is, adjust the distance between the glans seat 210, the circumcision knife 311 and the nail magazine 710, so that a safe closed nail height distance is reached between the nail magazine 710 and the glans seat 210, thereby ensuring the molding effect of the suture nail.

[0075] Related technologies, Figure 1 FIG. 2 shows a schematic diagram of the structure decomposition of the foreskin stapler 100. Figure 1 4 shows that the circumcision knife 311 and the nail pushing block 420 are both connected to the nail pushing seat 410. It can be understood that in the process of cutting the foreskin, the cutting knife first cuts the foreskin and then sutures the foreskin. This cutting method is easy to increase the patient's bleeding.

[0076] In view of the above technical problems, an embodiment of the present application provides a foreskin stapler 100, which utilizes a firing assembly 60 to be divided into two independent firings, namely a first firing and a second firing. The first firing realizes the suturing operation of the foreskin, and the second firing realizes the cutting operation of the foreskin. The method of suturing first and then cutting can reduce the amount of bleeding during the foreskin cutting process. In addition, after completing the first firing, using the limiting assembly 50 to block the movement of the pin pushing assembly 40 can not only ensure the molding effect of the suturing pin, but also reduce the operator's hand fatigue.

[0077] Specifically, please refer to Figure 2 and Figure 3 The foreskin stapler 100 further includes a limit assembly 50, which is rotatably connected to the housing 10 and is located at the proximal end of the nail pushing assembly 40. The nail pushing assembly 40 and the cutting structure 30 are both located in the housing 10 and are mounted on the nail support 20. The nail pushing assembly 40 and the cutting assembly 310 are two independent structures. It can be understood that when firing for the first time, the firing handle 610 acts on the nail pushing assembly 40 to achieve the suturing operation of the foreskin to be cut; when firing for the second time, the firing handle 610 acts on the cutting structure 30 to achieve the cutting operation of the foreskin.

[0078] Figure 2 2 shows a schematic diagram of the state before the first firing. Before the first firing, the limit assembly 50 is overlapped on the pin pusher assembly 40.

[0079] When the firing assembly 60 fires for the first time, the nail pushing assembly 40 moves in the first direction under the action of the firing assembly 60. Figure 2 The arrow s1 direction shown in the figure moves toward the distal end and can push the suture nail so that the suture nail can suture the foreskin to be cut. When the nail pushing assembly 40 moves toward the distal end, the limit assembly 50 can abut against the end of the nail pushing assembly 40. On the one hand, the nail pushing assembly 40 continuously acts on the foreskin to ensure the molding effect of the suture nail. On the other hand, it can also release the operator's hands and relieve hand fatigue. The firing handle 610 rotates to the original position under the action of the firing torsion spring, so that the second firing can be performed.

[0080] When the firing assembly 60 fires for the second time, since the pin pushing assembly 40 has completed its distal movement and is blocked by the limiting assembly 50, the firing assembly 60 acts on the cutting structure 30 and causes the cutting structure 30 to cut the foreskin to be cut.

[0081] It should be noted that the principle of suturing the foreskin with a suture staple is similar to that of a stapler. When the suture staple is formed on the foreskin, the operator needs to continuously apply a large force to ensure the forming effect of the suture staple. However, it is difficult for operators with less experience or less strength to grasp the control, and there is a situation where the suture staple forming effect is poor. The above embodiment uses the limiting component 50 to block the push staple component 40 that has completed the foreskin suturing, so that the push staple component 40 can continue to act on the foreskin to ensure the forming effect; in addition, during the process of forming the suture staple, the firing component 60 can be fired for the second time, which can not only ensure the forming effect of the suture staple, but also ensure the cutting efficiency of the foreskin stapler 100.

[0082] In an optional embodiment, the cutting structure 30 further includes a rotating assembly 320, which is connected to the proximal end of the cutting assembly 310. When the firing handle 610 is fired for the first time, the rotating assembly 320 is in the first position e, that is, Figure 2 When the rotating assembly 320 is in the first position e, when the firing handle 610 is fired for the first time, the rotating assembly 320 is not on the rotation path of the firing handle 610, and it can be understood that the firing handle 610 will not act on the rotating assembly 320 during its rotation.

[0083] After the first firing is completed, the nail pushing assembly 40 moves toward the distal end along the first direction under the action of the firing handle 610, and the nail pushing assembly 40 is stationary relative to the housing 10 under the action of the limiting assembly 50, and the rotating assembly 320 rotates from the first position e to the second position f. When the firing handle 610 fires the second time, the rotating assembly 320 is located on the rotation path of the firing handle 610, that is, the firing handle 610 acts on the rotating assembly 320 and drives the rotating assembly 320 and the cutting assembly 310 to move synchronously along the first direction toward the distal end, so as to achieve cutting of the foreskin that has been sutured.

[0084] Figure 4 and Figure 5 The figures show that the rotating assembly 320 is in the first position. Figure 5 The position pointed by the arrow e shown in FIG. 1 is the same as the second position f. Figure 5 Schematic diagram of the state of the position pointed by the arrow f shown in FIG. 1 . When the rotating assembly 320 is in the first position e, the firing handle 610 will not act on the rotating assembly 320 when rotating.

[0085] Figure 5, it is shown that the rotating assembly 320 can rotate clockwise from the first position e to the second position f. It should be noted that the rotating assembly 320 can also rotate counterclockwise, as long as the rotating assembly 320 after rotation can be on the rotation path of the firing handle 610 during the second firing. The specific rotation of the rotating assembly 320 is not specifically limited in the embodiment of the present application.

[0086] Furthermore, the cutting structure 30 further includes a blocking member 330, and the blocking member 330 is used to block the rotating assembly 320 so that the rotating assembly 320 is located at the first position e.

[0087] It can be understood that before the firing handle 610 is fired for the first time, the blocking member 330 blocks the rotating assembly 320 from rotating from the first position e to the second position f. When the blocking member 330 moves along the first direction and disengages from the rotating assembly 320 during the first firing, the rotating assembly 320 rotates from the first position e to the second position f.

[0088] In an alternative embodiment, Figure 8 3 and 4. It is shown that the blocking member 330 is the end of the firing handle 610. Before the firing handle 610 is fired for the first time, the rotating assembly 320 abuts against the side wall of the end of the firing handle 610 to prevent the rotating assembly 320 from rotating.

[0089] In another optional embodiment, the blocking member 330 is a baffle (not shown) formed by the pin pusher 410 extending near the rotating assembly 320. Before the firing handle 610 is fired for the first time, the baffle blocks the rotating assembly 320 from rotating. When the firing handle 610 is fired for the second time, the baffle moves toward the distal end along the first direction following the pin pusher 410 and separates from the rotating assembly 320. Of course, the blocking member 330 can also be other structures, which are not specifically limited in the embodiment of the present application.

[0090] In an alternative embodiment, please refer to Figure 6 and Figure 7 The rotating assembly 320 includes a first connecting member 321, a second torsion spring 322 and a rotating block 323. The first connecting member 321 is embedded in the knife seat 312. The second torsion spring 322 is connected to the first connecting member 321 and the rotating block 323 and is located between the first connecting member 321 and the rotating block 323. The rotating block 323 is rotatably connected to the first connecting member 321. Under the action of the second torsion spring 322, the rotating block 323 can rotate relative to the first connecting member 321 and rotate from the first position e to the second position f.

[0091] It can be understood that before the firing handle 610 is fired for the first time, the rotating block 323 abuts against the blocking member 330 under the action of the second torsion spring 322, that is, the blocking member 330 blocks the rotating block 323 from continuing to rotate. When the firing handle 610 completes the first firing, that is, the blocking member 330 moves toward the distal end along the first direction, the blocking member 330 disengages from the rotating block 323, and the rotating block 323 rotates from the first position e to the second position f under the action of the second torsion spring 322.

[0092] Furthermore, the knife seat 312 is provided with a second through hole 3121, and the first connecting member 321 is inserted into the second through hole 3121. When the firing handle 610 acts on the rotating block 323 and drives the rotating block 323 to move toward the distal end along the first direction, the knife seat 312 can be driven to move synchronously to achieve the cutting action of the foreskin.

[0093] Furthermore, the pin pusher seat 410 is provided with a first through hole 411, the first through hole 411 and the second through hole 3121 overlap at least partially, the first connecting member 321 is inserted into the first through hole 411 and the second through hole 3121, and the size of the first through hole 411 in the first direction is larger than the size of the second through hole 3121 in the second direction.

[0094] Furthermore, a bending portion is provided at the end of the first connecting member 321 close to the pin pushing seat 410 , and the bending portion is inserted into the first through hole 411 and the second through hole 3121 . The bending portion extends along a second direction, and the second direction is perpendicular to the first direction.

[0095] When the firing assembly 60 fires for the first time, the firing assembly 60 acts on the nail pusher 410, and the nail pusher 410 moves toward the distal end along the first direction. Before the first firing, the first connecting member 321 is located at the distal end of the first through hole 411; after the first firing, the first connecting member 321 is located at the proximal end of the first through hole 411.

[0096] It should be noted that, during the first firing process, the nail pushing assembly 40 moves toward the distal end along the first direction, and the cutting assembly 310 moves a distance toward the distal end along the first direction driven by the nail pushing assembly 40, but when the suture nail sutures the foreskin, the circumcision knife 311 does not contact the foreskin. Alternatively, the cutting assembly 310 remains stationary during the first firing process.

[0097] In an optional embodiment, the first connecting member 321 is provided with a mounting groove 3212, the first connecting member 321 is provided with a cylindrical protrusion 3211 and is located in the mounting groove 3212, the rotating block 323 is provided with a third through hole 3231 matching the cylindrical protrusion 3211, and the second torsion spring 322 is sleeved on the cylindrical protrusion 3211. The rotating block 323 can rotate around the cylindrical protrusion 3211, so that the rotating block 323 is at the first position e and the second position f.

[0098] In an optional embodiment, the rotating block 323 is provided with a notch 3232. When the rotating block 323 is at the second position f, the firing handle 610 can rotate the notch 3232 and abut against the rotating block 323 during firing, so that the firing handle 610 can drive the rotating block 323 to move toward the distal end along the first direction. The specific structure of the notch 3232 can be set according to the structure of the firing handle 610, and the firing handle 610 can drive the rotating block 323 to move, which is not specifically limited in the embodiment of the present application.

[0099] In an optional embodiment, the rotating block 323 is provided with a limiting edge 3233, which is the side of the mounting groove 3212. When the rotating block 323 is in the second position f, the limiting edge 3233 matches the side of the mounting groove 3212 to limit the rotation angle of the rotating block 323, thereby ensuring that the firing handle 610 can act on the rotating block 323 during the rotation process, thereby improving the structural stability of the foreskin stapler 100. The specific structure of the limiting edge 3233 can be set according to the structure of the side of the mounting groove 3212, and the embodiment of the present application does not make specific limitations.

[0100] Please refer to Figure 8 and Fig. 9 The limiting assembly 50 includes a first limiting block 510 and a first torsion spring 520. The first limiting block 510 is rotatably connected to the shell 10. The first torsion spring 520 is connected to the first limiting block 510. Under the action of the first torsion spring 520, the second end 512 of the first limiting block 510 is lifted while the first end 511 thereof falls.

[0101] Figure 8 , a schematic diagram of the state of the limit assembly 50 before the firing assembly 60 performs the first firing is shown. In the second direction, the first end 511 of the first limit block 510 overlaps the pin push assembly 40 under the action of the first torsion spring 520. It can be understood that the pin push assembly 40 can prevent the first limit block 510 from continuing to rotate.

[0102] Fig. 9, a schematic diagram of the state of the limit assembly 50 after the firing assembly 60 completes the first firing is shown. After the firing assembly 60 completes the first firing, the nail pushing assembly 40 moves toward the distal end along the first direction under the action of the firing handle 610 and disengages from the first limit block 510. The first limit block 510 rotates and abuts against the end of the nail pushing assembly 40 under the action of the first torsion spring 520, which can prevent the nail pushing assembly 40 from moving toward the proximal end along the first direction, that is, moving toward the original position. The first limit block 510 abuts against the end of the nail pushing assembly 40. On the one hand, the nail pushing assembly 40 and the nail support 20 are continuously matched to ensure the forming effect of the suture nail; on the other hand, the first limit block 510 can rotate to knock on the surface of the nail support 20 and make a sound to prompt the operator to release both hands accurately.

[0103] In an optional embodiment, the limiting assembly 50 further includes a reset button 530 , which is movably embedded in the housing 10 and can contact the second end 512 of the first limiting block 510 .

[0104] Figure 8 , a schematic diagram of the state of the firing assembly 60 before the first firing, in which the first stop block 510 is overlapped on the pin push assembly 40. In this state, the reset button 530 is trapped in the housing 10.

[0105] Fig. 9 , a schematic diagram of the state in which the firing assembly 60 completes the first firing, and the first stopper 510 abuts against the end of the pin pusher assembly 40. In this state, the second end 512 of the first stopper 510 is lifted and the reset button 530 is lifted, and at least a portion of the reset button 530 is moved to the outside of the housing 10.

[0106] During the first firing process, the firing assembly 60 can not only prompt the operator by making a sound when the first limit block 510 hits the nail seat 20, but also visually prompt the operator to release both hands. That is, when at least part of the reset button 530 moves to the outside of the shell 10, it means that the nail push assembly 40 and the nail seat 20 are matched, and the operator can release both hands.

[0107] Please refer to Figure 4 and Fig.10 The foreskin stapler 100 also includes a reset elastic member 90, which is preferably a compression spring, but is certainly not limited to this. The reset elastic member 90 is sleeved on the pin pusher assembly 40, and the reset elastic member 90 is located between the blocking protrusion 101 provided on the inner wall of the shell 10 and the first connecting member 321.

[0108] When the firing assembly 60 completes the second firing, the cutting assembly 310 completes cutting the foreskin, and the operator presses the reset button 530 in the second direction, that is, presses the reset button 530 toward the inside of the shell 10 to lift the first end 511 of the first limit block 510, thereby making the first end 511 of the first limit block 510 disengage from the nail pushing assembly 40, and the nail pushing assembly 40 and the rotating assembly 320 move toward the proximal end along the first direction under the action of the reset elastic member 90.

[0109] For further information, please refer to Figure 6 The pin pusher assembly 40 includes a pin pusher seat 410 and a moving block 430, and the moving block 430 is connected to the pin pusher seat 410. Before the firing assembly 60 fires for the first time, the first end 511 of the first stopper 510 overlaps the surface of the moving block 430. After the firing assembly 60 completes the first firing, the first end 511 of the first stopper 510 abuts against the end of the moving block 430. The specific shape of the moving block 430 can be set according to demand, and the embodiment of the present application is not limited thereto. For example, the surface for overlapping the first stopper 510 is a planar structure.

[0110] The suturing and cutting steps of the foreskin stapler 100 provided in the embodiment of the present application are as follows:

[0111] The first step is to adjust the distance between the nail support 20 and the nail magazine 710 by adjusting the adjusting member 80 so that the distance between the two reaches the safe closing nail height distance. In this state, the first end 511 of the first limit block 510 overlaps the nail push assembly 40, that is, Figure 2 Schematic diagram of the positional relationship between the pin pusher assembly 40 and the first limiting block 510 is shown in FIG.

[0112] Step 2: Rotate the firing handle 610 to fire the first shot. The firing handle 610 rotates and pushes the nail pusher assembly 40 along the Figure 2 The middle arrow s1 moves toward the distal end, and the first end 511 of the first limiting block 510 rotates under the action of the first torsion spring 520 and abuts against the end of the pin pushing assembly 40 . Fig. 9 It is shown in the figure that after the firing handle 610 is fired, the first end 511 of the first limiting block 510 abuts against the end of the nail pushing assembly 40, and knocks against the surface of the nail support 20 and makes a sound.

[0113] Step 3: Release both hands, and the firing handle 610 rotates to the original position, i.e., the position before the first firing, under the action of the firing torsion spring. During the resetting process of the firing handle 610, the rotating block 323 moves from the first position e to the second position f under the action of the second torsion spring 322, and the rotating block 323 at the second position f is located on the rotation path of the firing handle 610. Fig.11FIG. 3 shows a schematic diagram of a state in which the firing handle 610 rotates to the initial position after the operator releases both hands. In this state, the first limit block 510 abuts against the end of the pin pusher assembly 40, and the rotating block 323 has rotated to the second position f.

[0114] Step 4: The firing handle 610 fires for the second time. The firing handle 610 acts on the rotating block 323 and pushes the rotating assembly 320 to move toward the distal end along the first direction and drives the cutting assembly 310 to move synchronously to cut the foreskin. Fig.12 , a schematic diagram of the state of the firing handle 610 performing a second firing is shown. In this state, the firing handle 610 acts on the rotating block 323 and pushes the rotating block 323 and the cutting assembly 310 to move toward the distal end along the first direction. Fig.13 FIG. 6 shows that the firing handle 610 is reset to the original position after completing the second firing. During the resetting process of the firing handle 610 , the rotating assembly 320 moves toward the original position under the action of the reset elastic member 90 .

[0115] In step 5, the operator presses the reset button 530 to cause one end of the first limit block 510 to tilt up and disengage from the end of the moving block 430 , so that the cutting assembly 310 and the nail pushing assembly 40 can move toward the proximal end along the first direction under the action of the reset elastic member 90 . Fig.14 The figure shows the state of the pin pusher assembly 40 and the rotating assembly 320 after reset, that is, after pressing the reset button 530, the first end 511 of the first limit block 510 is tilted, and the pin pusher assembly 40 moves to the original position, that is, the position before the first firing, under the action of the reset elastic member 90, and the rotating assembly 320 is located at the second position f due to the action of the second torsion spring 322.
