Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a circumcision stapler. Background Art

[0002] The foreskin stapler is a medical device used in circumcision surgery. It uses titanium nails or stainless steel nails to replace the traditional manual suturing method to quickly complete the foreskin cutting and anastomosis.

[0003] The working principle of the circumcision stapler is similar to that of a stapler. During the operation, in order to achieve the stapling effect and compress the tissue to stop bleeding, the circumcision stapler needs to be kept for a period of time after the anastomosis. During this period, the doctor needs to apply a large force on the stapler and maintain it for a period of time, which can easily cause the doctor's hand fatigue and cause the applied force to be unstable, affecting the effect of the operation. Summary of the invention

[0004] In view of this, an embodiment of the present application provides a circumcision stapler to solve at least one problem existing in the background technology.

[0018] Wherein, before the firing assembly is fired, in a second direction perpendicular to the first direction, the first end of the first limit block overlaps the surface of the firing push block under the action of the first torsion spring;

[0019] When the firing assembly fires, the firing push block moves along the first direction, and the first end of the first limiting block rotates to the end of the firing push block under the action of the first torsion spring to prevent the firing push block from moving.

[0020] In conjunction with the first aspect of the present application, in an optional implementation manner, the limit assembly further includes:

[0025] In conjunction with the first aspect of the present application, in an optional embodiment, the foreskin stapler further includes:

[0026] A first resetting elastic member, sleeved on the firing push block;

[0027] When the firing push block moves toward the kiss cutting assembly along the first direction, the first resetting elastic member is compressed and deformed;

[0028] When the limiting assembly is separated from the firing push block, the firing push block moves to the initial position under the action of the first reset elastic member overcoming the elastic force.

[0029] In conjunction with the first aspect of the present application, in an optional implementation manner, the housing is provided with a first mounting hole;

[0040] A handle safety member, rotatably connected to the housing and used to prevent the firing handle from rotating;

[0041] Wherein, in the unused state, the blocking member covers and presses on the handle safety member to prevent it from rotating, and the handle safety member prevents the firing handle from rotating;

[0042] The adjusting knob is rotated to make the anvil move along the first direction toward the adjusting knob, and the blocking member moves synchronously with the anvil. When the blocking member is disengaged from the handle safety member, the firing handle can rotate relative to the shell and fire the anastomosis assembly to engage with the anvil.

[0043] In conjunction with the first aspect of the present application, in an optional implementation, the adjustment knob is provided with a through adjustment hole;

[0078] like Figure 1a and Figure 2 As shown, the foreskin stapler 100 includes a housing 10, an anvil 20, an anastomosis assembly 30 and a firing assembly 40. The anvil 20 is provided with a receiving groove 210 for receiving the glans penis, and the foreskin to be cut is covered in the receiving groove 210 of the anvil 20. The anvil 20 is detachably connected to the housing 10. The firing assembly 40 is movably connected to the housing 10. The anastomosis assembly 30 is moved in a first direction, i.e., under the firing action of the firing assembly 40. Figure 1a Move in the direction of arrow s1 shown in the figure to suture and cut the foreskin covering the nail seat 20.

[0079] The kiss cutting assembly 30 includes a staple cartridge assembly 310, a staple pusher assembly 320 and a cutting knife 330. The cutting knife 330 is an annular structure. The staple cartridge assembly 310 includes an annular staple cartridge 311 and a staple cartridge sleeve 312. The staple cartridge 311 contains suture staples, and the staple cartridge 311 is installed in the staple cartridge sleeve 312. Under the combined action of the firing assembly 40 and the staple support 20, the staple pusher assembly 320 pushes the suture staples to suture the foreskin incision, and at the same time, the cutting knife 330 removes excess foreskin.

[0080] The principle of using suture staples to sew up the foreskin incision is similar to that of a stapler. When using suture staples to sew up the foreskin incision, the doctor needs to continuously apply a large force to form the suture staples on the foreskin. On the one hand, it is difficult for inexperienced doctors to grasp the duration; on the other hand, long-term holding can easily cause doctor's hand fatigue and unstable force application, especially for doctors with less strength.

[0081] Based on this, an embodiment of the present application provides a foreskin stapler 100, in which the limiting assembly 50 can enable the anastomosis assembly 30 to continue to be anastomosed with the stapler seat 20 after the firing assembly 40 is fired, and the doctor does not need to apply force continuously. This can not only ensure the molding effect of the suture staples, but also reduce the doctor's hand fatigue.

[0082] Specifically, Figure 1a , Figure 3a and Figure 3b As shown, the foreskin stapler 100 further includes a limiting assembly 50 , which is movably connected to the shell 10 . Figure 3a A schematic diagram of the state of the firing assembly 40 before firing is shown, and the limiting assembly 50 contacts the firing assembly 40 in a second direction, and the second direction is perpendicular to the first direction. Figure 3b The schematic diagram shows the state when the firing assembly 40 is fired, that is, when the anastomosis assembly 30 is anastomosed with the anvil 20. In the first direction, one end of the limit assembly 50 abuts against the firing assembly 40, and the limit assembly 50 can prevent the firing assembly 40 from moving to the initial position, so that the anastomosis assembly 30 and the anvil 20 can continue to anastomose, ensure the molding effect of the suture staples, and reduce the fatigue of the doctor's hands. In addition, after the firing assembly 40 is fired, the limit assembly 50 abuts against one end of the firing assembly 40 and hits the surface of the anvil 20 to produce an impact sound, so as to remind the doctor that the anastomosis assembly 30 and the anvil 20 are in anastomosis state.

[0083] It should be noted that, based on the fact that the limit assembly 50 overlaps the firing assembly 40 in the second direction before firing, the limit assembly 50 will not affect the movement of the firing assembly 40 along the first direction. After the firing assembly 40 moves along the first direction, the limit assembly 50 rotates and makes one end abut against the end of the firing assembly 40, so that the kissing assembly 30 and the nail seat 20 continue to fit together.

[0084] In an optional embodiment, the firing assembly 40 includes a firing handle 410 and a firing push block 420, wherein the firing handle 410 is rotatably connected to the housing 10, and a portion of the firing handle 410 is located inside the housing 10, and the other region of the firing handle 410 is located outside the housing 10, so that the doctor can fire the foreskin stapler 100 through the firing handle 410. When the anvil 20 is installed in the housing 10, the firing push block 420 is sleeved on the anvil 20. When the firing handle 410 rotates relative to the housing 10, the firing push block 420 can be driven to move toward the anastomosis assembly 30 along a first direction, so that the firing push block 420 drives the anastomosis assembly 30 to move, thereby causing the anastomosis assembly 30 to anastomose with the anvil 20, thereby achieving cutting and suturing of the foreskin.

[0085] Optionally, the firing push block 420 is connected to the firing handle 410, and when the firing handle 410 rotates, the firing push block 420 can be driven to move in the first direction. Alternatively, the firing push block 420 is disposed adjacent to the portion of the firing handle 410 located in the housing 10, and when the firing handle 410 rotates, the firing push block 420 can be pushed to move in the first direction. Both of the above embodiments can realize the present application of driving the firing push block 420 to move by rotating the firing handle 410, and further enable the firing push block 420 to push the kiss cutting assembly 30 to move.

[0086] Figure 3cIt is shown that in the first direction, the upper limit assembly 50 abuts against the end of the firing push block 420, so that the anastomosis assembly 30 and the anvil 20 are continuously anastomosed, and the firing handle 410 is rotated to the initial position under the action of the second torsion spring 411, releasing the doctor's pressing force on the firing handle 410, relieving the doctor's hand fatigue, and ensuring the stability of the force between the anastomosis assembly 30 and the anvil 20, thereby ensuring the suturing and cutting effect of the foreskin.

[0087] In an optional embodiment, 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 housing 10, and 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 of the first limiting block 510 falls. It can be understood that the first limiting block 510 is similar to a seesaw, and in a natural state, the second end 512 of the first limiting block 510 will tilt up.

[0088] Before the firing assembly 40 fires, in the second direction, i.e. Figure 1a In the direction of arrow s2 shown in the figure, the first end 511 of the first limiting block 510 overlaps the surface of the firing push block 420 under the action of the first torsion spring 520.

[0089] When the firing assembly 40 is fired, the firing push block 420 is driven by the firing handle 410 to move in a first direction. Figure 1a The first end 511 of the first limiting block 510 moves in the direction of the arrow s1 shown in the figure, 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 firing push block 420 to block the movement of the firing push block 420, thereby allowing the anastomosis assembly 30 to continue to anastomose with the nail seat 20; at the same time, the first end 511 of the first limiting block 510 rotates under the action of the first torsion spring 520 and knocks on the surface of the nail seat 20 and makes a sound to prompt the doctor of the current state of the stapler, that is, the firing push block 420 is disengaged from the first limiting block 510, and the anastomosis assembly 30 and the nail seat 20 are in anastomosis state.

[0090] It can also be understood that before the firing assembly 40 is fired, when the first limit block 510 overlaps the upper surface of the firing push block 420, the contact distance between the first limit block 510 and the firing push block 420 in the first direction is equal to the distance moved by the firing push block 420 along the first direction, and the distance moved by the firing push block 420 is also the distance that can safely close the nail height.

[0091] In an optional embodiment, the foreskin stapler 100 further includes a first resetting elastic member 7a, which is sleeved on the firing push block 420. The first resetting elastic member 7a is preferably a compression spring, but is certainly not limited thereto.

[0092] When the firing push block 420 moves along the first direction, Figure 1a When the arrow s1 direction shown in the figure moves toward the kiss cutting assembly 30, the first reset elastic member 7a is compressed and deformed. When the limit assembly 50 is separated from the firing push block 420, the firing push block 420 moves to the initial position under the action of the first reset elastic member 7a overcoming the elastic force.

[0093] In this embodiment, after the foreskin stapler 100 completes the suturing and cutting action, the stapler assembly moves to the initial position under the action of the first reset elastic member 7a overcoming the elastic force, which makes it easy to disassemble the stapler seat 20 and remove the cut foreskin.

[0094] 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 .

[0095] Figure 1a and Figure 3a A schematic diagram of the state of the foreskin stapler 100 before the firing assembly 40 is fired is shown. In this state, since the first end 511 of the first limit block 510 overlaps the firing push block 420, the second end 512 of the first limit block 510 is not lifted, and the reset button 530 is sunk into the shell 10.

[0096] Figure 3b A schematic diagram of the state of the foreskin stapler 100 after the firing assembly 40 is fired is shown. In this state, since the first limit block 510 abuts against the end of the firing push block 420, the second end 512 of the first limit block 510 is lifted and the reset button 530 is lifted, and the reset button 530 is moved to the outside of the shell 10.

[0097] When the reset button 530 moves to the outside of the housing 10, it indicates that the first end 511 of the first limit block 510 is in contact with the firing push block 420. In this state, the doctor can release the gripping force applied to the firing handle 410. After the doctor releases the gripping force applied to the firing handle 410, the anastomosis assembly 30 and the anvil 20 continue to anastomose. After the suture staples are formed for a period of time, the doctor presses the reset button 530 to make the first end 511 of the first limit block 510 disengage from the firing push block 420, and the firing push block 420 moves to the initial position. In addition, at the moment when the first limit block 510 is disengaged from the firing push block 420, the first end 511 of the first limit block 510 rotates under the action of the first torsion spring and hits the surface of the anvil 20, making a knocking sound.

[0098] In this embodiment, the reset button 530 is lifted to the outside of the shell 10 to produce an obvious visual prompt to the doctor, and the impact sound can also produce an obvious auditory prompt, visually and auditorily prompting the doctor to release the gripping force applied to the firing handle 410 at this time, thereby relieving the doctor's hand fatigue. In addition, after a period of time, only the reset button 530 needs to be pressed to loosen the anastomosis assembly 30 and the dowel seat 20, which is simple to operate.

[0099] In an alternative embodiment, if Figure 2 and Figure 4a As shown, the reset button 530 is provided with a pressing portion 531, a first connecting portion 532 and a first limiting portion 533, the two ends of the first connecting portion 532 are respectively connected to the pressing portion 531 and the first limiting portion 533, the pressing portion 531 is at least partially located outside the housing 10, the first limiting portion 533 is located inside the housing 10, the first connecting portion 532 is plugged into the first mounting hole 110 provided on the housing 10, and the first connecting portion 532 can move along the second direction in the first mounting hole 110. When the reset button 530 is lifted by the second end 512 of the first limiting block 510, the first limiting portion 533 abuts against the inner wall of the housing 10 to prevent the reset button 530 from being separated from the housing 10.

[0100] Figure 4a FIG. 5 shows that the stapler is in an initial state and the reset button 530 is sunken in the housing 10 under the action of its own gravity. The doctor may cause the stapler to flip over when moving the stapler, that is, the reset button 530 may be moved out of the housing in the initial state, and then the second end 512 of the first limit block 510 cannot lift the reset button 530 when the stapler is stapled, which affects the doctor's judgment on the operation of the stapler.

[0101] Based on this, Figure 1b , Figure 2 and Figure 4b As shown, the reset button 530 is further provided with a second connection portion 534 and a second stop portion 535, and the two ends of the second connection portion 534 are respectively connected to the second stop portion 535 and the first stop portion 533. The first stop block 510 is provided with a hollow area 513, and the second connection portion 534 is inserted into the hollow area 513. In this way, when the stapler is in the initial state, the first stop block 510 can prevent the reset button 530 from being lifted, and when the stapler is in the stapled state, the lifting of the second end 512 of the first stop block 510 can cause the reset button 530 to be lifted synchronously, so as to provide a visual prompt to the doctor.

[0102] Optionally, the hollow area 513 is a through hole or a notch, and the second connecting portion 534 is inserted into the through hole or the notch. Figure 4b The hollow area 513 is shown as a gap, which is not specifically limited in the embodiment of the present application.

[0103] In an alternative embodiment, if Figure 1a As shown, the foreskin stapler 100 also includes an adjusting knob 6a and a handle safety piece 6c. The adjusting knob 6a is connected to the end of the anvil 20 away from the anastomosis assembly 30. The adjusting knob 6a is used to adjust the position of the anvil 20 relative to the shell 10 so that the distance between the anvil 20 and the staple magazine 311 can reach the range of safe closed staple height.

[0104] Preferably, the outer wall of the end of the anvil 20 close to the adjusting knob 6a is provided with an external thread, and the inner wall of the adjusting hole 6a1 of the adjusting knob 6a is provided with an internal thread matching the external thread. Of course, the adjustment method of the adjusting knob 6a is not limited to this.

[0105] The handle safety piece 6c is rotatably connected to the housing 10, and the handle safety piece 6c is used to prevent the firing handle 410 from rotating. The firing handle 410 is provided with a groove matching the handle safety piece 6c. When the handle safety piece 6c is placed in the groove of the firing handle 410, the firing handle 410 cannot rotate to fire.

[0106] According to the related art, when the handle safety piece 6c is not placed in the groove of the firing handle 410, the firing handle 410 can be fired regardless of whether the anvil 20 is adjusted into place, and there is a risk of misfiring.

[0107] Based on this, the embodiment of the present application utilizes the blocking member 6b to prevent the handle safety member 6c from rotating. When the nail support 20 is adjusted to a preset position range, that is, a range that can reach the height of a safe closed nail, the handle safety member 6c can be rotated and the firing handle 410 can be fired. The blocking member 6b enables the foreskin stapler 100 to have an anti-misfire safety function, which can avoid the occurrence of accidental firing.

[0108] Specifically, the blocking member 6b is sleeved on the anvil 20. Before the foreskin stapler 100 is used, that is, before the firing assembly 40 is fired, the blocking member 6b overlaps the surface of the handle safety member 6c in the second direction to prevent the handle safety member 6c from rotating, thereby making the handle safety member 6c prevent the firing handle 410 from rotating.

[0109] Rotating the adjusting knob 6a causes the anvil 20 to move toward the adjusting knob 6a in the first direction, and the anvil 20 drives the blocking member 6b to move synchronously. When the blocking member 6b is separated from the handle safety member 6c, the handle safety member 6c can rotate and separate from the firing handle 410, and the firing handle 410 can rotate relative to the housing 10 and fire the anastomosis assembly 30 to anastomose with the anvil 20.

[0110] It can be understood that, in the process of adjusting the position of the nail support 20 using the adjusting knob 6a, when the blocking member 6b disengages from the handle safety member 6c, it indicates that the distance between the nail support 20 and the nail magazine 311 can reach the range of safe closed nail height, thereby ensuring the molding effect of the suture nail and the suturing effect of the foreskin.

[0111] The above-mentioned circumcision stapler 100 uses the blocking member 6b to realize the foolproof safety of the circumcision stapler 100, thereby improving the safety of the circumcision stapler 100; the limiting component 50 is used to abut against the firing component 40, so that the circumcision stapler 100 can be continuously in a self-maintaining pressure, which can not only ensure the stability of the pressure, but also release the pressure of the doctor's hands; the circumcision stapler 100 is provided with safety measures before and after firing, which greatly improves the safety and stability of the circumcision stapler 100.

[0112] In an alternative embodiment, if Figure 1a and Figure 5 The foreskin stapler 100 further comprises a prompt rod 8a, which is connected to one end of the anvil 20 away from the anastomosis assembly 30. Of course, the prompt rod 8a can be integrally formed with the anvil 20, which is not limited in the present embodiment.

[0113] Figure 5 The figure shows that the end of the prompt rod 8a is flush with the opening of the adjustment hole 6a1 to prompt the doctor that the blocking member 6b is disengaged from the handle safety member 6c. The handle safety member 6c is rotatable and the foreskin stapler 100 is in a state ready to fire at any time.

[0114] The prompt rod 8a can not only prompt the doctor through visual prompts, but also through tactile prompts. When the doctor feels through touch that the end of the prompt rod 8a is flush with the opening of the adjustment hole 6a1, it indicates that the doctor can rotate the handle safety piece 6c.

[0115] Furthermore, if Figure 1a and Figure 2 As shown, the foreskin stapler 100 further includes a second limit block 8b and a second resetting elastic member 7b, the second limit block 8b is connected to the anvil seat 20, the second resetting elastic member 7b is sleeved on the anvil seat 20, and the blocking member 6b abuts against the surface of the second limit block 8b under the elastic force of the second resetting elastic member 7b. The second resetting elastic member 7b is preferably a compression spring, but is not limited thereto.

[0116] The blocking member 6b can always abut against the surface of the second limit block 8b under the elastic force of the second reset elastic member 7b to ensure the position and posture of the blocking member 6b, thereby ensuring the accuracy of the timing of releasing the safety of the handle safety member 6c.

[0117] The suturing and cutting steps of the foreskin stapler 100 provided in the embodiment of the present application are as follows:

[0118] first step, Figure 3a , a schematic diagram of the initial state of the foreskin stapler 100 is shown, that is, the first end 511 of the first limit block 510 overlaps the upper surface of the firing push block 420 in the second direction; and the blocking member 6b overlaps the upper surface of the handle safety member 6c in the second direction, so that the blocking member 6b blocks the handle safety member 6c from rotating, and further the handle safety member 6c blocks the firing handle 410 from rotating and firing.

[0119] In the second step, the adjusting knob 6a is rotated to make the dowel seat 20 move along the first direction toward the adjusting knob 6a. During the movement of the dowel seat 20, the blocking member 6b is driven to move synchronously, and the end of the prompt rod 8a connected to the dowel seat 20 is flush with the opening of the adjusting hole 6a1.

[0120] Figure 5 It is shown in the figure that the prompt rod 8a moves to be flush with the opening of the adjustment hole 6a1, and the blocking member 6b is separated from the handle safety member 6c, and this state is a firing state.

[0121] The third step is to rotate the firing handle 410 , and the firing handle 410 rotates to drive the firing push block 420 to move toward the kiss cutting assembly 30 along the first direction, and make the kiss cutting assembly 30 fit with the nail seat 20 .

[0122] Figure 3b 2 shows that when the anastomosis assembly 30 and the anvil 20 are anastomosed, the first end 511 of the first limit block 510 abuts against the end of the firing push block 420 in the first direction, and the first limit block 510 blocks the movement of the firing push block 420, thereby allowing the anastomosis assembly 30 to continue to anastomose with the anvil 20. The reset button 530 is moved out of the housing 10 under the lifting action of the second end 512 of the first limit block 510, and at the same time, the first end 511 of the first limit block 510 hits the surface of the anvil 20, visually and auditorily notifying the doctor that the first limit block 510 abuts against the end of the firing push block 420, that is, the anastomosis assembly 30 and the anvil 20 are in anastomosis.

[0123] Step 4: When the doctor sees that the reset button 530 is moved out of the housing 10 , the doctor releases the force applied to the firing handle 410 , and the firing handle 410 rotates to the initial position under the action of the second torsion spring 411 .

[0124] Figure 3c The figure shows that the anastomosis assembly 30 and the anvil 20 are in an anastomosis state, and the firing handle 410 rotates to the initial position under the action of the second torsion spring 411 to relieve the doctor's hand fatigue.

[0125] Step 5: After the anastomosis assembly 30 and the anvil seat 20 have been anastomosed for a period of time, the doctor presses the reset button 530 to separate the first end 511 of the first limit block 510 from the end of the firing push block 420, and the firing push block 420 moves to the initial position under the action of the first reset elastic member 7a. The anastomosis time of the anastomosis assembly 30 and the anvil seat 20 is generally about 10 seconds, which can be selected according to the specific situation to ensure the suture staple forming effect.

[0126] Figure 3d FIG. 4 is a schematic diagram showing a state in which the firing push block 420 and the kiss cutting assembly 30 move to the initial position under the action of the first reset elastic member 7a.
