[0061] In the present invention, the terms "first" and "second" are only used for the purpose of clear description and cannot be understood as the relative importance of the indicated features or the number of the indicated technical features. Therefore, the features defined as "first" and "second" can explicitly include at least one of the features. In the description of the present invention, "multiple" means at least two, such as two, three, etc.; "several" means at least one, such as one, two, three, etc., unless otherwise clearly and specifically defined.

[0062] In the present invention, unless otherwise clearly defined, the terms "install", "connect", "connect", "fix", "set", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] In the present invention, unless otherwise clearly defined, a first feature being “on”, “above”, “above”, “below”, “below”, “below” or “below” a second feature may mean that the first feature is in direct contact with the second feature, or the first feature and the second feature are in indirect contact with each other through an intermediate medium.

[0064] like Figure 1 As shown, the circumcision stapler 100 (hereinafter referred to as "stapler 100") includes a housing 10, anastomosis assembly 20, firing assembly 30 and anvil assembly 40. The anvil assembly 40 includes a glans seat 410 for accommodating the glans penis. During the operation, the glans penis is placed in the accommodating cavity of the glans seat 410, and the foreskin to be cut is stretched proximally to cover the glans seat 410 and fixed, so that the firing assembly 30 is used to fire the anastomosis assembly 20 and the glans seat 410 for anastomosis and cutting.

[0065] The kiss cutting assembly 20 includes a staple cartridge assembly 210, a staple pusher assembly 220 and a cutting knife 230. The cutting knife 230 is an annular structure. The staple cartridge assembly 210 includes an annular staple cartridge 211 and a staple cartridge sleeve 212. The staple cartridge 211 contains suture staples, and the staple cartridge 211 is installed on the staple cartridge sleeve 212. The staple pusher assembly 220 includes a staple pusher block 222 and a staple pusher body 221. A plurality of staple pusher blocks 222 are circumferentially distributed around the axis of the annular cutting knife 230. The staple pusher block 222 is used to push out the suture staples in the staple cartridge 211 and act on the foreskin. The cutting knife 230 is connected to the staple pusher body 221. The staple pusher body 221 moves under the firing action of the firing assembly 30 and drives the staple pusher block 222 and the cutting knife 230 to move, so that both the suture staples and the cutting knife 230 act on the foreskin.

[0066] The firing assembly 30 includes a firing handle 310, a firing push block 320 and a connecting rod 330, and the firing handle 310 and the firing push block 320 are connected by the connecting rod 330. The firing handle 310 is movably mounted outside the housing 10, and the firing push block 320 moves under the firing action of the firing handle 310 and pushes the nail pushing assembly 220 to move, so as to suture and cut the foreskin covering the glans base 410.

[0067] Related technologies, such as Figure 2 As shown, the anvil assembly 40 is integrally formed and has a relatively long length. During the process of inserting the anvil assembly 40 into the shell 10, it is difficult to align and needs to be inserted repeatedly, which is time-consuming and laborious for the doctor.

[0068] Based on this, a circumcision stapler 100 is provided in an embodiment of the present application. The stapler 100 splits the stapler seat assembly 40 into a detachable connecting piece 420 and a glans seat 410. The connecting piece 420 is movably connected to the inside of the shell 10. During the assembly process, it is only necessary to assemble the shorter glans seat 410 on the connecting piece 420 to complete the assembly. In addition, the stapler 100 uses the driving assembly 60 to move the distal end of the connecting piece 420 to a visual environment, and then assembles the glans seat 410 on the connecting piece 420, which is convenient for the doctor to operate and can be accurately aligned without repeated insertion, saving time and effort.

[0069] Specifically, Figure 3 and Figure 4 As shown, the stapler 100 further includes a drive assembly 60, which is embedded in the housing 10 and at least partially located outside the housing 10. One end of the drive assembly 60 contacts the proximal end of the connector 420 and can rotate relative to the housing 10. Under the force of the drive assembly 60, the connector 420 is driven to move toward the distal end along the first direction, and the distal end of the connector 420 is assembled on the glans base 410 in a visualized environment. The doctor's hand acts on the drive assembly 60 located outside the housing 10 to drive the connector 420 to move along the first direction.

[0070] Compared with the longer anvil seat assembly 40 in the prior art, the embodiment of the present application splits the longer anvil seat assembly 40 into two parts, namely a connecting piece 420 and a glans seat 410, and the shorter glans seat 410 is convenient for insertion.

[0071] The visualization environment can be understood as the environment that the doctor can visually see. When the distal end of the connecting piece 420 moves toward the distal end under the action of the driving assembly 60, the distal end of the connecting piece 420 can be seen from the distal end of the stapler 100, which makes it easier for the doctor to align the glans seat 410 with the connecting piece 420, thereby improving assembly efficiency.

[0072] In an optional embodiment, the nail pusher body 221 is provided with a first visualization window 2211, the nail magazine sleeve 212 is provided with a second visualization window 2121, and the first visualization window 2211 and the second visualization window 2121 at least partially overlap and form a visualization environment. It can be understood that the connecting member 420 moves to the distal end under the driving force of the driving assembly 60, and the doctor can not only see the distal end of the connecting member 420 from the distal end of the stapler 100, but also can see the distal end of the connecting member 420 through the first visualization window 2211 and the second visualization window 2121. The first visualization window 2211 and the second visualization window 2121 are respectively provided on the side walls of the nail pusher body 221 and the nail magazine sleeve 212, so that the doctor's observation angle can be increased and the alignment effect of the connecting member 420 and the glans seat 410 can be improved.

[0073] In addition, the first visualization window 2211 and the second visualization window 2121 are also used to observe the tightening of the foreskin to be cut.

[0074] In an alternative embodiment, if Figure 4 and Figure 5 As shown, the driving assembly 60 includes a sliding member 610 and a swinging member 620. The sliding member 610 is embedded in the housing 10 and can slide relative to the housing 10 along a first direction under the action of the doctor's hand. The swinging member 620 is movably connected to the sliding member 610 and rotatably connected to the housing 10. The swinging member 620 rotates under the action of the sliding force of the sliding member 610 to drive the connecting member 420 to move along the first direction.

[0075] It can be understood that the sliding member 610 is located outside the shell 10 to facilitate the doctor's operation. The sliding member 610 moves along the first direction. During the movement of the sliding member 610, the swinging member 620 is driven to rotate around the shell 10. The swinging member 620 rotates to push the connecting member 420 to move along the first direction.

[0076] Specifically, the sliding member 610 moves toward the proximal end along the axis direction of the connecting member 420 under the action of the doctor. Figure 4 The swing member 620 moves in the direction of the arrow s2 shown in FIG. 1 , and the swing member 620 rotates counterclockwise under the action of the sliding member 610. Figure 4 The swing member 620 rotates in the direction of the arrow r1 shown in the figure, and the swing member 620 rotates to push the connecting member 420 to move toward the far end along its axis direction, that is, along Figure 4 Move in the direction of arrow s1 shown in the figure and move the distal end of the connecting piece 420 to the visualization environment to facilitate the doctor to assemble the glans seat 410 and the connecting piece 420.

[0077] Furthermore, if Figure 4 and Figure 6As shown, the driving assembly 60 further includes a first pin shaft 630, the first pin shaft 630 is connected to the swinging member 620 and the housing 10, and the swinging member 620 rotates relative to the housing 10 around the first pin shaft 630. The first pin shaft 630 separates the swinging member 620 into a first swinging portion 621 and a second swinging portion 622, the first swinging portion 621 is movably connected to the sliding member 610, and the second swinging portion 622 contacts the connecting member 420, and the ratio of the length of the first swinging portion 621 to the length of the second swinging portion 622 is in a range of 1 / 4 to 3 / 4. The above ratio range enables the sliding member 610 to move a large distance by only moving a short distance, which has the effect of amplifying the stroke and further improving the sliding efficiency of the sliding member 610.

[0078] The connecting member 420 is provided with a first through hole 421 , and the swinging member 620 is inserted into the first through hole 421 . The swinging member 620 can push the connecting member 420 to move when it rotates, and vice versa, the movement of the connecting member 420 can also push the swinging member 620 to rotate.

[0079] Figure 4 , a schematic diagram showing that the first elastic member 70 is sleeved on the connecting member 420 and is in a compressed state is shown, that is, a schematic diagram showing a state in which the distal end of the connecting member 420 moves to the visualization environment under the action of the driving assembly 60. When the clamping force acting on the driving assembly 60 is released, the connecting member 420 moves toward the proximal end along the first direction under the action of the first elastic member 70 overcoming the elastic force. Generally, the doctor's hand acts on the driving assembly 60 and generates a clamping force. Of course, the clamping force can also be generated by driving a driving member, for example: driving a motor, etc., which is not limited in the embodiments of the present application. The first elastic member 70 is preferably a compression spring, but is of course not limited to this.

[0080] In this embodiment, after the distal end of the connecting member 420 is assembled with the glans seat 410 in a visualized environment, the connecting member 420 moves toward the proximal end along the first direction under the action of the first elastic member 70, and brings the glans seat 410 into the interior of the shell 10, thereby realizing the preliminary assembly of the glans seat 410 and the anastomosis assembly 20.

[0081] In an alternative embodiment, if Figure 7a and Figure 7b As shown, the glans base 410 is provided with a spring sheet 411, and the inner wall of the spring sheet 411 is provided with a snap-on protrusion 412. The far end of the connecting member 420 is provided with a snap-on groove 423 matching the snap-on protrusion 412, the connecting member 420 is inserted into the glans base 410, and the snap-on protrusion 412 is snap-on to the snap-on groove 423 to realize the snap-on connection between the connecting member 420 and the glans base 410.

[0082] Preferably, the glans seat 410 includes two elastic sheets 411 arranged opposite to each other, and the two elastic sheets 411 are distributed along the circumference thereof to ensure the clamping firmness of the connecting member 420 and the glans seat 410. Of course, the glans seat 410 can also be provided with more than two elastic sheets 411, and the more than two elastic sheets 411 are distributed circumferentially around the axis of the glans seat 410 to improve the clamping firmness of the connecting member 420 and the glans seat 410. The number of elastic sheets 411 provided on the glans seat 410 can be set according to the size of the proximal end of the glans seat 410, and the embodiment of the present application does not limit it.

[0083] The distal end of the connecting piece 420 that is clamped to the glans seat 410 gradually narrows toward its distal end and has an arc-shaped structure, so as to facilitate the insertion of the connecting piece 420 into the glans seat 410 and improve assembly efficiency.

[0084] Furthermore, if Figure 4 and Figure 5 As shown, the anvil assembly 40 further includes a blocking piece 430, which is connected to the connecting member 420. When the first elastic member 70 is sleeved on the connecting member 420, one end of the first elastic member 70 is connected to the blocking piece 430, and the other end contacts the housing 10. The blocking piece 430 is used to block the first elastic member 70. The blocking piece 430 can be connected to the connecting member 420 by a fastener, or can be integrally formed with the connecting member 420, which is not specifically limited in the embodiment of the present application.

[0085] The connecting member 420 further includes a limiting portion 440, which is a square structure and is used to limit the rotation of the connecting member 420. The limiting portion 440 matches the square structure groove provided inside the housing 10. Of course, the structure of the limiting portion 440 is not limited thereto.

[0086] In an optional embodiment, the circumcision stapler 100 also includes an adjusting member 50, which is embedded in the shell 10 and can rotate relative to the shell 10. The connecting member 420 can contact the adjusting member 50 under the elastic force of the first elastic member 70. Under the adjustment of the adjusting member 50, the connecting member 420 and the glans seat 410 can move relative to the shell 10, and make the glans seat 410 and the anastomosis assembly 20 reach a preset distance, which is also the safety closure nail height distance.

[0087] Specifically, the proximal end of the connecting member 420 is provided with an external thread 422, and the adjusting member 50 is provided with an adjusting hole 510, the adjusting hole 510 extends along the first direction, and the inner wall of the adjusting hole 510 is provided with an internal thread matching the external thread 422, and the adjusting member 50 is rotated to make the connecting member 420 and the glans seat 410 move along the first direction.

[0088] In an alternative embodiment, if Figure 8As shown, the shell 10 is provided with a prompt mark 110. When the sliding member 610 moves to the corresponding position of the prompt mark 110, the distance between the glans seat 410 and the anastomosis assembly 20 reaches a preset distance, that is, the nail height distance can be safely closed.

[0089] As an example, the indicator mark 110 is a first safety indicator line and a second safety indicator line provided on the housing 10, and a safe firing area is formed between the first safety indicator line and the second safety indicator line. It can be understood that when the sliding member 610 moves to the safe firing area, i.e., between the first safety indicator line and the second safety indicator line, it indicates that the safe closure nail height distance is reached between the glans seat 410 and the anastomosis assembly 20, and the stapler 100 can be fired.

[0090] In this embodiment, the prompt mark 110 can visually prompt the doctor to the firing timing of the stapler 100, thereby improving the suturing and cutting accuracy of the stapler 100.

[0091] Related technologies, such as Figure 2 As shown, before the stapler 100 is assembled, the stapler 100 is a three-section type, namely, an adjusting member 50, a device body, and an anvil seat. After the anvil seat is assembled on the device body, the adjusting member 50 is connected to the anvil seat and the position of the anvil seat relative to the device body is adjusted. The three-section stapler 100 has many assembly steps and is easy to lose.

[0092] Based on this, Figure 4 and Figure 5 As shown, in the embodiment of the present application, a limiting groove 520 is provided on the adjusting member 50, and the limiting groove 520 forms an annular groove along the circumference of the housing 10. The housing 10 is provided with a limiting protrusion 120, which can rotate along the limiting groove 520 to limit the adjusting member 50 from moving along the axial direction of the housing 10.

[0093] It can be understood that the adjusting member 50 is always connected to the housing 10. Compared with the three-stage stapler 100, the present embodiment is a two-stage stapler, which can reduce the assembly process of the stapler 100 and can greatly reduce the loss phenomenon.

[0094] The suturing and cutting steps of the circumcision stapler 100 provided in the embodiment of the present application are as follows:

[0095] Figure 9a A schematic diagram of the state of the connecting member 420 , the adjusting member 50 and the driving assembly 60 in the initial state is shown, that is, the proximal end of the connecting member 420 contacts the adjusting member 50 under the elastic force of the first elastic member 70 .

[0096] In the first step, the sliding member 610 moves along Figure 4 Move in the direction of arrow s2 in the figure to drive the connecting member 420 to move toward the distal end along the first direction. Figure 4Move in the direction of arrow s1 shown in the figure, and make the distal end of the connecting piece 420 assembled on the glans seat 410 in a visualized environment, which is convenient for doctors to operate in a visualized environment, thereby improving the alignment accuracy between the glans seat 410 and the connecting piece 420 and improving the assembly effect.

[0097] Figure 4 FIG. 4 shows that the connecting member 420 is moved to the visualization environment under the action of the driving assembly 60 so that the doctor can align and assemble the glans seat 410 with the connecting member 420 .

[0098] Step 2: Release the force on the driving assembly 60, and the connecting member 420 moves toward the proximal end along the first direction under the action of the elastic force of the first elastic member 70. Figure 9b The proximal end of the connecting member 420 can move to the adjusting member 50 under the action of the first elastic member 70 .

[0099] Figure 9b It is shown in the figure that after the driving assembly 60 is released, the connecting member 420 moves to the adjusting hole 510 of the adjusting member 50 under the action of the first elastic member 70 overcoming the elastic force, and the glans seat 410 follows the connecting member 420 to move into the shell 10.

[0100] The third step is to rotate the adjusting member 50 so that the connecting member 420 moves toward the proximal end along the first direction. Fig.9c The connecting member 420 moves in the direction of the arrow s2 shown in the figure, and the distance between the glans seat 410 and the nail magazine 211 reaches the safe closing nail height. During the movement of the connecting member 420, the swinging member 620 is driven to rotate, and the swinging member 620 rotates to push the sliding member 610 along the Fig.9c Move in the direction of arrow s1 shown in the figure. When the sliding member 610 moves to the area of ​​the prompt mark 110, it indicates that the safe closed nail height distance is reached between the glans seat 410 and the nail magazine 211. The prompt mark 110 is used to remind the doctor to improve the adjustment accuracy of the stapler 100, thereby improving the suturing and cutting effect of the stapler 100.

[0101] Fig.9c FIG. 4 shows that after the adjusting member 50 is rotated and adjusted, the connecting member 420 and the glans seat 410 are simultaneously moved along Fig.9c Move in the direction of arrow s1 shown in the figure and make the nail magazine 211 and the glans seat 410 reach a safe closed nail height.

[0102] Step 4: Use the firing assembly 30 to fire, so that the anastomosis assembly 20 and the anvil seat are anastomosed and cut, and the foreskin suture cutting is completed. The firing push block 320 performs a reset action under the action of the second elastic member 340 overcoming the elastic force.
