Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, and particularly relates to a glans cap assembly and a prepuce cutting anastomat with the glans cap assembly. BACKGROUND

[0002] At present, most prepuce cutting operations are performed by using a prepuce cutting anastomat, and the prepuce is sutured by using the anastomotic nails in the anastomat, so as to reduce the operation time and alleviate the pain of the patient. For example, a harpoon nail type prepuce cutting anastomat is provided in the existing Chinese patent No. CN209107510U. The prepuce cutting anastomat includes a glans cap, a cutting knife and anastomotic nails. In the surgical process of the prepuce cutting anastomat provided in the above structure, the glans cap is first sleeved on the end of the penis, the excess prepuce is sleeved outside the glans cap, then the excess prepuce is fixed on the glans cap, the glans cap is connected to the anastomat main body with the cutting knife, the cutting of the prepuce is completed by using the cutting knife and the glans cap, and finally the anastomotic nails in the nail cartridge are pushed out to clamp and suture the skin tissue at the cutting position.

[0003] When the doctor fixes the excess prepuce on the penis by using the glans cap in the above prepuce cutting anastomat, the cutting position of the outer plate of the prepuce outside can only be roughly determined, and the cutting position of the inner plate of the prepuce inside and the frenulum and the accurate cutting position of the outer plate of the prepuce cannot be directly observed and controlled by the naked eye, so that the prepuce length cannot be accurately and controllably cut. At this time, when the operation is performed by using the existing prepuce cutting anastomat, the doctor can only determine the cutting position of the inner and outer plates of the prepuce and the frenulum by the vague feeling, and cannot accurately control it. In this case, the operation cutting may not be complete or too much may be cut. Especially for the adolescent boys who have not fully developed, since the length of the inner plate of the prepuce is large, the cutting position of the prepuce cannot be accurately determined during the operation, and the prepuce may be cut too much or too little, and the prepuce is still in a half-covered state after the operation.

[0004] The existing Chinese patent publication No. CN207462131U, CN203749513U, CN102614009B entitled "Disposable prepuce cutting anastomat" all provide a technical solution comprising an inner ring and an outer ring tightly coupled to each other for packaging and fixing. The disposable prepuce cutting anastomat provided by the above-mentioned uses the interaction between the outer ring and the inner ring to extrude the prepuce, so that the prepuce is ischemic and necrotic and separated from the human body. Therefore, the patient needs to continuously wear the anastomat on the penis for 7-21 days after the operation using the above-mentioned disposable prepuce cutting anastomat until the prepuce and the ring after the lateral cutting are naturally shed, or the ring is actively disassembled. Although this method can avoid the problem of disassembling the stitches or nails, the long-term wearing of the anastomat after the operation also causes certain discomfort to the patient's body and psychology. Moreover, due to the clamping and pressing of the ring, some patients have postoperative wound infection, cracking and other problems. Especially for younger patients, it also increases the difficulty of postoperative care. SUMMARY

[0005] The purpose of the present application is to solve the problem that the glans cap assembly cannot accurately judge and control the cutting position of the inner and outer prepuce and frenulum when the glans cap of the existing prepuce cutting anastomat is fixed on the end of the penis, and the problem that the existing disposable prepuce cutting anastomat needs to be worn for a period of time after the operation, causing discomfort to the patient's body and psychology, and being prone to postoperative wound infection and cracking.

[0035] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0036] Reference is made to Figures 1-5The foreskin cutting anastomat 200 is used for cutting the redundant foreskin of the penis. The anastomat body 230 of the foreskin cutting anastomat 200 is matched with the foreskin cap assembly 100, and the redundant foreskin of the penis is cut by the annular cutting knife 232 on the anastomat body 230, and then the foreskin is sutured by the anastomat needle in the needle cartridge 233. The foreskin cap assembly 100 provided by the application can make the doctor clearly observe and control the cutting position of the foreskin tissue during the foreskin cutting operation, and not only can the cutting position of the outer plate of the foreskin be determined, but also the cutting position of the inner plate of the foreskin and the frenulum can be determined after the foreskin tissue is folded outward from the foreskin cap assembly 100. After the cutting position on the foreskin cap assembly 100 is determined, the anastomat body 230 of the foreskin cutting anastomat 200 is matched with the foreskin cap assembly 100 to cut and suture, and the whole foreskin cutting operation is completed. After the suture is completed by the anastomat needle of the foreskin cutting anastomat 200, the whole foreskin cap assembly 100 can be removed from the end of the penis, so that the components of the foreskin cap assembly 100 are not fixed on the end of the penis, and the patient's physical and psychological discomfort after the operation is avoided, and the postoperative care is more difficult. The foreskin cap assembly 100 and the foreskin cutting anastomat 200 provided by the application are especially suitable for use by young boys, can greatly shorten the operation time, reduce the amount of bleeding during the operation and the operation difficulty of the doctor, cut the wound neatly and beautifully, and can avoid the problems of incomplete cutting or excessive cutting after the operation, no bleeding, light edema, short pain time, and the infection and cracking probability after the operation is greatly reduced, and the postoperative care is more difficult.

[0037] Embodiment one:

[0038] Reference Figures 1-2 The foreskin cap assembly 100 provided by the application comprises an inner ring 10, an outer ring 20 arranged on the radial outer side of the inner ring 10 and a mounting portion 30 detachably fixed on the inner ring 10. The foreskin cap assembly 100 can be used together with the anastomat body 230 of the foreskin cutting anastomat 200 as shown in Figure 6 The foreskin cap assembly 100 mainly comprises an inner ring 10, an outer ring 20 and a mounting portion 30.

[0039] In the operation process, first, the inner ring 10 needs to be sleeved on the end of the penis, so that the redundant prepuce tissue around the penis is wrapped outside the inner ring 10, and then the outer ring 20 is sleeved outside the inner ring 10 covered with redundant prepuce tissue, so as to preliminarily fix the redundant prepuce tissue between the inner ring 10 and the outer ring 20. At this time, by adjusting the relative position of the outer ring 20 and the outside of the prepuce tissue, the cutting position of the outer plate of the prepuce can be accurately determined. After the cutting position of the inner plate of the prepuce is determined, the redundant prepuce tissue is folded outwardly outside the outer ring 20, so as to expose the inner ring 10 inside the prepuce tissue. At this time, by adjusting the relative position of the inner ring 10 relative to the inside of the prepuce tissue, the cutting position of the inner plate of the prepuce and the frenulum can be accurately determined. After the cutting position of the redundant prepuce tissue is determined twice, the mounting portion 30 is fixed on the inner ring 10, and the fixed connection between the inner ring 10 and the mounting portion 30 is realized. Then, the fixed connection between the whole glans cap assembly 100 and the anastomat body 230 is realized through the mounting portion 30. The mounting portion 30 is detachably fixed on the top of the inner ring 10, so that the cutting position of the prepuce can be adjusted by the cooperation between the inner ring 10 and the outer ring 20, and after the cutting position is determined, the inner ring 10 and the anastomat body 230 are fixedly connected. Finally, the mounting portion 30 is fixed on the anastomat body 230, and the cutting and suturing process of the prepuce is realized through the butt joint between the anastomat body 230 and the inner ring 10. After the suturing of the prepuce is completed, the glans cap assembly 100 and the anastomat body 230 are separated, and the outer ring 20 on the glans cap assembly 100 is removed, and the inner ring 10 and the mounting portion 30 fixed on the end of the penis are taken off together, and the operation process of the whole prepuce cutting anastomat is completed. The glans cap assembly 100 provided by the application can be completely taken off from the end of the penis after the prepuce cutting operation is completed, and does not need to be fixed on the penis after the operation, so as to avoid the psychological fear of the patient for the postoperative ring placement.

[0040] Specifically, as Figure 1As shown, the inner ring 10 in the meatus of penis cover assembly 100 includes a fixed ring 11 which can be sleeved on the end of the penis, and an annular anvil 111 is arranged on the top surface of the fixed ring 11. The annular anvil 111 arranged on the top surface of the fixed ring 11 is used to dock with the annular cutting knife 232 and the nail cartridge 233 in the circumcision cutting anastomat 200, so as to realize the cutting and suturing process of the prepuce. A first connecting part 112 which can be attached to the outer ring 20 is arranged on the outer circumferential surface of the fixed ring 11. The first connecting part 112 arranged on the outer circumferential surface of the fixed ring 11 is used to attach to the outer ring 20, so as to ensure that the excess prepuce tissue can be clamped between the inner ring 10 and the outer ring 20, thereby fixing the prepuce tissue on the inner ring 10. On the one hand, the cutting position can be changed due to the movement of the prepuce tissue when the inner ring 10 and the outer ring 20 are tightly fixed, that is, when the circumcision cutting anastomat 200 is cutting, and on the other hand, the cutting position of the outer plate, the inner plate and the frenulum of the prepuce can be controlled when the inner ring 10 and the outer ring 20 are loosely fixed, that is, when the prepuce is preliminarily controlled.

[0041] Specifically, as shown in the drawings, Figure 6 As shown, the inner ring 10 in the meatus of penis cover assembly 100 is fixedly connected with the anastomat body 230 through the mounting part 30. The inner ring 10 and the mounting part 30 can be fixedly connected through mutual buckling, threaded connection or magnetic attraction. The mounting part 30 is arranged to detachably fix the inner ring 10 on the anastomat body 230 of the circumcision cutting anastomat 200. How the mounting part 30 realizes the relative detachable fixed connection with the inner ring 10 is not limited herein. Moreover, the mounting part 30 is provided with a positioning part (not shown in the drawings) which is connected with the anastomat body 230. Correspondingly, when the mounting part 30 is fixedly connected with the inner ring 10, the inner ring 10 also has a positioning part (not shown in the drawings) which can be aligned with the mounting part 30, so as to ensure that the inner ring 10 and the anastomat body 230 can be accurately aligned in the radial direction after the anastomat body 230 is fixedly connected with the inner ring 10. The positioning part can be a positioning column arranged on the annular anvil 111 of the inner ring 10, or can be realized by the relative positioning between the inner ring 10 and the mounting part 30 when they are fixedly connected.

[0042] Further, as shown in the drawings, Figure 2 As shown, the first connecting part 112 of the inner ring 10 in the meatus of penis cover assembly 100 provided in the first embodiment of the present application is an annular groove arranged on the fixed ring 11. As shown in the drawings, Figure 2As shown, the outer circumferential surface of the fixing ring 11 of the inner ring 10 is provided with an annular groove arranged around the fixing ring 11, which facilitates the fixation of the outer ring 20 on the inner ring 10. In the embodiment, an elastic silica gel gasket (not shown in the figure) can also be arranged in the annular groove of the first connecting part 112 of the inner ring 10. When the outer ring 20 clamps the inner ring 10 and the redundant prepuce tissue, a certain elastic space can be generated by the silica gel gasket arranged in the annular groove, so as to regulate the position of the prepuce relative to the inner ring 10 or the outer ring 20.

[0043] The first connecting part 112 arranged on the inner ring 10 in the foreskin cap assembly 100 provided by the application is an annular groove, so that the outer ring 20 sleeved thereon can be composed of two half rings 21 as shown in Figure 1 , or a hemostatic ring 40 as shown in Figure 3 . In the embodiment, the outer ring 20 has the structure as shown in Figure 1 , that is, the outer ring 20 arranged outside the inner ring 10 is composed of two half rings 21 which are spliced to form a circular structure, one end of the two half rings 21 is hinged, and the other end is fixed by a clamping piece 22. The circular structure formed by the two half rings 21 can be completely sleeved on the outer circumferential surface of the inner ring 10, and one end of the two half rings 21 is hinged, so that the other end as a movable end can be relatively away from the opening or relatively connected to form a closed opening. The outer ring 20 is sleeved on the inner ring 10 through the opening. The clamping piece 22 arranged on the movable end of the two half rings 21 can be used to fix the movable end of the two half rings 21, so that a closed opening is formed between the two half rings 21. In the embodiment, the clamping piece 22 arranged on the outer ring 20 can not only realize the complete closing of the outer ring 20, but also realize the tightness adjustment of the two half rings 21 fixed on the inner ring 10 through the clamping piece 22, that is, two different connection states of loose fixation and tight fixation can be realized.

[0044] Specifically, as shown in Figure 2 , in the embodiment, the inner wall of the two half rings 21 of the outer ring 20 is provided with a second connecting part 211 which can be attached to the first connecting part 112 of the inner ring 10. The second connecting part 211 of the outer ring 20 is a protrusion arranged on the inner wall of the half ring 21 along the radial direction. When the outer ring 20 is sleeved on the inner ring 10, the protrusion of the outer ring 20 is embedded in the annular groove of the inner ring 10, so as to realize the relative fixation of the inner ring 10 and the outer ring 20 in the axial direction. Figure 2As shown, when the outer ring 20 is sleeved on the inner ring 10, the two are in a tightly fixed state. At this time, the second connecting part 211 on the outer ring 20 can be completely attached to the first connecting part 112 of the inner ring 10. Specifically, the protrusions provided on the outer ring 20 can be completely embedded in the annular groove of the inner ring 10. In order to effectively clamp the preputial tissue between the outer ring 20 and the inner ring 10, the height of the annular groove H1 on the inner ring 10 and the height of the protrusion H2 on the outer ring 20 must be such that the height of the annular groove H1 is greater than the height of the protrusion H2, so that when the annular groove and the protrusion are embedded in each other, the part of the engagement can reserve space for the preputial tissue to fill. Preferably, the height of the annular groove H1 is 1.5-2 times the height of the protrusion H2, so that the protrusion of the outer ring 20 can have a certain space for movement in the axial direction. If the height difference between the annular groove H1 and the protrusion H2 is too small, the embedding space between the inner ring 10 and the outer ring 20 is completely used to accommodate the preputial tissue, and the mutual embedding of the two cannot be achieved. If the height difference between the two is too large, the inner ring 10 and the outer ring 20 have space in the axial direction after being tightly fixed by mutual engagement, which will cause relative movement in the axial direction, which is not conducive to subsequent cutting of the preputial tissue.

[0045] Specifically, as shown in the drawings, Figure 1 The clamping piece 22 on the outer ring 20 includes an elastic buckle 221 provided on one half ring 21 and at least one anti-unhooking hook 222 connected to the elastic buckle 221 provided on the other half ring 21. The inner ring 10 and the outer ring 20 are relatively fixed in the radial direction by the clamping piece 22. As shown in the drawings, Figure 1 In this embodiment, the clamping piece 22 on the outer ring 20 has two spaced-apart anti-unhooking hooks 222 on the single half ring 21. When the elastic buckle 221 on the clamping piece 22 is fixed to the anti-unhooking hook 222 close to one side thereof, the outer ring 20 is in a loose fixed state. When the elastic buckle 221 on the clamping piece 22 is fixed to the anti-unhooking hook 222 away from one side thereof, the outer ring 20 is in a tightly fixed state. When the outer ring 20 is initially fixed to the inner ring 10, the elastic buckle 221 is lapped on the anti-unhooking hook 222 close to one side thereof to achieve loose fixing, at this time, the outer ring 20 and the inner ring 10 have a certain gap therebetween, which not only can accommodate excess preputial tissue to be cut, but also can make the preputial assembly have a certain space for movement up and down in the gap to adjust the relative position of the prepuce and the top surface of the inner ring 10 or the outer ring 20. When the position of the prepuce and the top surface of the inner ring 10 is determined, the elastic buckle 221 is lapped on the anti-unhooking hook 222 away from one side thereof to achieve tight fixing, at this time, the outer ring 20 and the inner ring 10 completely clamp the preputial tissue located therebetween, so that the preputial tissue is completely fixed relative to the inner ring 10 or the outer ring 20, providing preparation for cutting of the circumcision anastomat 200.

[0046] Further, as shown in Figure 1 The mounting portion 30 in the foreskin cap assembly 100 provided by the present application comprises a lower connecting piece 31 fixedly connected with the inner ring 10 and an upper connecting piece 32 connected with the anastomat body 230. The upper connecting piece 31 and the lower connecting piece 32 are fixedly connected to form an integral body. The lower connecting piece 31 of the mounting portion 30 comprises a base 311 fixedly connected with the inner ring 10, and a conical groove 312 in communication with the fixing ring 11 is arranged on the bottom surface of the base 311. The upper connecting piece 32 comprises a connecting screw 321 arranged on the top surface of the base 311, and an adjusting screw thread 322 connected with the anastomat body 230 is arranged on the top of the connecting screw 321. The conical groove 312 arranged on the base 311 is in communication with the inner ring 10, so that when the inner ring 10 is sleeved on the penis, the penis part penetrating through the inner ring 10 can extend into the conical groove of the base 311. The fourth connecting portion 313 connected with the inner ring 10 is arranged on the base 311, and the fixed connection with the inner ring 10 is realized through the fourth connecting portion 313. As shown in Figure 6 When the foreskin cap assembly 100 is fixedly connected with the anastomat body 230, the connecting screw 321 of the lower connecting piece 32 in the mounting portion 30 completely extends into the anastomat body 230, and the fixed connection with the anastomat body 230 is realized through the adjusting screw thread 322 arranged on the connecting screw 321.

[0047] Specifically, as shown in Figure 1 The mounting portion 30 provided by the present application further comprises a fixing portion 314 arranged on the base 311 of the lower connecting piece 31 for fixing the foreskin to be cut. In the embodiment, the fixing portion 314 is a plurality of clamping positions uniformly distributed along the circumference on the outer side of the base 311. Of course, the fixing portion 314 can also be a clamping position structure with multiple layers from bottom to top arranged on the outer circumferential surface of the base 311 (not shown in the figure), and the clamping positions with different heights can be used to fix the foreskin tissue with different lengths. The clamping position can be used to hook the foreskin tissue to be cut, and fix the excess foreskin tissue on the mounting portion 30, which is beneficial to the foreskin cutting anastomat 200 to cut it. The foreskin tissue beyond the clamping position can be cut by the doctor according to the actual needs during the operation, so that when the mounting portion 30 is inserted into the anastomat body 230, the excess foreskin tissue will not block the mounting portion 30 from being fixed to the anastomat body 230. Arranging a plurality of clamping positions on the outer circumference of the base 311 can stretch and fix the foreskin, so as to ensure that the foreskin does not shrink during cutting, and the foreskin cutting anastomat 200 can cut better, more beautiful, and the foreskin cutting length is more controllable.

[0048] Specifically, as shown in Figure 2As shown, in the embodiment, the inner ring 10 further comprises an upper connecting portion 12 fixedly connected to the top of the fixing ring 11 and the lower connecting piece 31 of the mounting portion 30, and the center of the upper connecting portion 12 is provided with a through hole 121 communicating the conical groove 312 of the lower connecting piece 31 with the fixing ring 11. The upper connecting portion 12 extends upward from the top surface of the inner ring, and the through hole 121 arranged in the middle is a horn-shaped through hole with an opening gradually increasing from bottom to top. When the inner ring 10 is fixed on the mounting portion 30, the through hole 121 is butted with the conical groove 312 on the lower connecting piece 31 of the mounting portion 30. The upper connecting portion 12 of the inner ring 10 has a third connecting portion 122 connected with the lower connecting piece 31 of the mounting portion 30, and the third connecting portion 122 is correspondingly arranged with a fourth connecting portion 313 on the lower connecting piece 31, that is, if the third connecting portion 122 on the inner ring 10 is an internal thread structure, the fourth connecting portion 313 on the lower connecting piece 31 is a correspondingly arranged external thread structure. As shown in the figure, Figure 2 As shown, in the embodiment, the third connecting portion 122 on the inner ring 10 is an annular clamping groove arranged on the upper connecting portion 12, and the fourth connecting portion 313 correspondingly arranged on the lower connecting piece 31 is an annular clasp. The inner ring 10 and the mounting portion 30 are detachably fixedly connected by clamping each other.

[0049] The foreskin cap assembly 100 provided by the application comprises three parts of an inner ring 10, an outer ring 20 and a mounting portion 30. During the operation, the cutting positions of the outer plate of the foreskin outside and the inner plate of the foreskin inside and the frenulum can be directly observed and controlled by the cooperation of the inner ring 10 and the outer ring 20, and then the fixed inner ring 10 and the outer ring 20 are locked on the anastomat main body 230 for cutting.

[0050] Embodiment two:

[0051] As shown, Figure 3As shown, it is a perspective exploded view schematic diagram of a meatus of penis cap assembly 120 provided by the second embodiment of the present application. The second embodiment is different from the first embodiment in that the outer ring 40 sleeved outside the inner ring 10 is a hemostatic ring. The hemostatic ring is a ring-shaped component with a certain elasticity, and the inner diameter of the hemostatic ring is smaller than the outer diameter of the inner ring 10. Correspondingly, in this embodiment, the first connecting portion 113 of the inner ring 10 is an arc-shaped groove with a circular arc structure arranged on the outer circumferential surface of the fixed ring 11. The arc-shaped groove on the first connecting portion 113 is fitted with the circular cross section of the hemostatic ring, so as to realize the relative fixation between the outer ring 40 and the inner ring 10 in the radial and axial directions. In this embodiment, the outer ring 40 adopts the structure of the hemostatic ring. When observing the incision position of the inner plate and the frenulum of the prepuce by folding the prepuce tissue, an external force is needed to pull one side of the hemostatic ring outward, so as to move the prepuce tissue between the inner ring 10 and the outer ring 40. When the incision position of the inner plate and the frenulum of the prepuce is determined, the external force is released, and the hemostatic ring is fixed in the arc-shaped groove of the inner ring 10 by the elasticity of the hemostatic ring itself, thereby playing a role of fixing the prepuce. The hemostatic ring is a medical elastic silicone ring, which is cheaper, easier to obtain, and easier to operate than the outer ring 20 formed by the two half rings 21 used in the first embodiment, and is easy to realize.

[0052] Further, in this embodiment, the fixing portion 315 arranged on the base 311 of the lower connecting piece 31 of the mounting portion 30 is an annular protrusion arranged around the outer circumferential surface of the base 311, and a fastening edge 3151 for tightening the prepuce tissue to be cut thereon is formed between the annular protrusion and the base 311. During the operation, the prepuce tissue to be cut can be tightened on the fastening piece 3151 by using the hemostatic ring, medical ligation line and other components, so as to play a role of stretching and fixing the prepuce, and ensure that the prepuce will not be contracted when the prepuce cutting anastomat 200 is cutting.

[0053] Embodiment three:

[0054] As Figure 4 and Figure 5As shown in the figure, it is a foreskin cap assembly 130 provided in the third embodiment of the present application. The foreskin cap assembly 130 provided in the embodiment is different from the first embodiment in that the first connecting part 114 of the inner ring 10 in the foreskin cap assembly 130 is an annular protrusion provided on the fixing ring 11, and the second connecting part 212 of the outer ring 20 is a groove provided on the inner wall of the half ring 21 along the radial direction. When the outer ring 20 is sleeved on the inner ring 10, the annular protrusion of the inner ring 10 is embedded in the groove of the outer ring 20. In the embodiment, the fixing ring 11 on the inner ring 10 extends outward along the radial direction by the annular protrusion, and correspondingly, the second connecting part 212 provided on the outer ring 20 composed of two half rings 21 is provided with a groove for embedding the annular protrusion, so that the relative fixation between the inner ring 10 and the outer ring 20 in the axial and radial directions can be achieved.

[0055] Specifically, as shown in the figure, Figure 5 As shown in the figure, it is a cross-sectional view when the outer ring 20 is tightly sleeved on the inner ring 10. In this state, the outer circumferential surface of the annular protrusion on the inner ring 10 can be completely fitted to the inner wall of the groove of the outer ring 20. In order to ensure that the inner ring 10 and the outer ring 20 can be fixedly clamped when clamping the foreskin tissue, the height of the annular protrusion provided on the inner ring 10 is H4, and the height of the groove provided on the outer ring 20 is H3. The height H3 of the groove provided on the outer ring 20 must be greater than the height H4 of the annular protrusion. Preferably, the height H3 of the groove on the outer ring 20 should be 1.5-2 times the height H4 of the annular protrusion.

[0056] At the same time that the annular protrusion of the inner ring 10 is embedded in the groove 212 of the outer ring 20, the annular anvil 111 provided on the inner ring 10 is not blocked by the outer ring 20. When the foreskin cap assembly 130 is fixed to the anastomat main body 230, the annular cutting knife 232 and the staple cartridge 233 of the anastomat main body 230 can be inserted into the outer ring 20 and docked with the annular anvil 111 on the top surface of the inner ring 10 for cutting and suturing.

[0057] Embodiment four:

[0058] As shown in the figure, Figure 6 The present application also provides a foreskin cutting anastomat 200. The foreskin cutting anastomat 200 comprises an anastomat main body 230 and the foreskin cap assembly 100 described above. The foreskin cutting anastomat 200 determines the cutting position of the outer plate, the inner plate and the frenulum of the foreskin by using the foreskin cap assembly 100 provided in the first embodiment, and then inserts the anastomat main body 230 to realize the control of the anastomat main body 230 by clamping a pair of handles 235 on the side of the anastomat main body 230, and cut and suture the redundant foreskin tissue. Specifically, as shown in the figure, Figure 6As shown, the front end of the stapler body 230 is provided with a receiving chamber 231 for the mounting portion 30 of the glans cap assembly 100, an annular cutting blade 232 disposed around the receiving chamber 231 and abutting against the annular blade anvil 111 on the inner ring 10 of the glans cap assembly 100, and a staple cartridge 233 disposed around the annular cutting blade 232. An adjustment bolt 234 is provided at the rear end of the stapler body 230, which is fixedly connected to the mounting portion 30. The receiving chamber 231 at the front end of the stapler body 230 is used to accommodate and position the lower connecting member 31 of the mounting portion 30 of the glans cap assembly 100. The upper connecting member 32 of the mounting portion 30 is inserted into the interior of the stapler body 230 and connected to the adjustment bolt 234 at the rear end. The adjustment bolt 234 can be threadedly engaged with the adjustment thread 322 on the upper connecting member 32, thereby locking the upper connecting member 32 to the stapler body 230.

[0059] During a circumcision procedure, after the glans hood assembly 100 has determined the foreskin incision position, it is secured to the stapler body 230 via the mounting portion 30. The handles 235 located on either side of the stapler body 230 are then controlled to move the annular cutting blade 232 at the front end of the stapler body 230 toward the annular anvil 111 of the inner ring 10 of the glans hood assembly 100. Once the foreskin at the anvil 111 is completely cut, the staples in the stapler cartridge 233 are extended to abut against the anvil 111, suturing the cut foreskin. Once the stapler body 230 has completed cutting and suturing the foreskin, the adjustment bolt 234 at the end of the stapler body 230 is adjusted to separate the glans hood assembly 100 from the stapler body 230. Next, the outer ring 20 in the glans hood assembly 100 is removed from the outside of the inner ring 10, thereby removing the inner ring 10 and the mounting portion 30 located inside, thereby completing the entire circumcision operation.

[0060] The foreskin cutting anastomat 200 provided by the present application adopts the foreskin cap assembly 100, so that the doctor can accurately judge the accurate cutting position of the outer plate, the inner plate and the frenulum during the operation process, and can accurately control the cutting position during the operation, thereby avoiding the problem that the foreskin is still in a half-covered state after the operation. The foreskin cutting anastomat 200 cuts by using the annular cutting knife 232 on the anastomat body 230, ensures the cutting accuracy, makes the cutting wound neat and beautiful, and finally sutures by using the suturing nails arranged in the nail cartridge 233 on the anastomat, and after the suture is completed, the foreskin cap assembly 100 can be completely removed from the end of the penis, and no instrument needs to be retained on the penis after the operation, so that the patient does not cause unnecessary psychological burden after the operation. The foreskin cutting anastomat 200 provided by the present application is used for foreskin cutting operation, and only once the nail is removed after the operation, the postoperative bleeding, pain and edema are lighter, the risk of infection and cracking is lower, and the wound after healing is beautiful. The foreskin cutting anastomat 200 provided by the present application can greatly improve the cutting accuracy while shortening the operation time and reducing the pain of the patient.

[0061] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
