Description

Technical Field

[0001] The present invention relates to a medical device, in particular to a foreskin regulating and limiting device. Background Art

[0002] Circumcision staplers are commonly used during circumcision procedures, improving surgical efficiency, reducing bleeding, and ensuring aesthetically pleasing postoperative incisions. However, most existing circumcision staplers fail to protect the frenulum during circumcision and anastomosis, nor to precisely position the inner and outer foreskin plates. This often results in accidental frenulum incision and damage, as well as over- or undercutting of the inner and outer foreskin plates, which negatively impacts the appearance of the circumcision. Safely protecting the frenulum before circumcision and achieving precise adjustment and reliable fixation of the inner and outer foreskin plates remains a challenge. The applicant's previous patent employed a technique combining an external retaining ring and an internal stopper to secure the foreskin. However, in actual use, it was found that this design could not achieve both precise adjustment and reliable fixation of the foreskin. Adjustable staplers often exhibit unreliable fixation, with the external retaining ring and internal stopper easily disengaging during operation, leading to adjustment failure. However, fixed staplers can cause the foreskin to become stuck and unable to adjust properly, leading to accidental incision and damage. Without these two functionalities working in tandem, their respective functions cannot be fulfilled, resulting in poor clinical effectiveness. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a foreskin adjustment limit device to ensure that the outer fixing ring and the inner limit seat will not separate from each other during adjustment, and are locked and fixed after the adjustment and positioning are completed. After the upper limit member is removed, the exposure of the cutting area on the inner limit seat is not affected, so that precise adjustment and reliable fixation are achieved at the same time, and the subsequent cutting and anastomosis work can be carried out smoothly.

[0004] The present invention adopts the following technical solution: a foreskin adjustment limit device, including an annular body, with an opening on the annular body, the opening can be opened or closed by changing the shape of the annular body, and the annular body is provided with a locking structure on both sides of the opening that can be locked to keep the opening in a closed state, the annular body includes an upper limit member and a lower limit member, the upper limit member is detachably arranged on the lower limit member, and the upper limit member forms a structural blockage on the upper part of the lower limit member.

[0005] As an improvement, the upper limit member forms a structural barrier on the upper part of the lower limit member, the inner diameter of which is smaller than the upper edge of the lower limit member.

[0006] As an improvement, the upper limit member is an arc-shaped piece arranged on the upper part of the lower limit member. When the opening is closed, the arc-shaped piece forms a ring. The arc-shaped piece and the lower limit member are detachably connected through an easily disconnected connection point.

[0007] As an improvement, the arc-shaped piece is provided with relatively extending blocking parts on both sides of the opening, and the blocking parts on both sides are staggered in height or inner and outer surfaces. When the opening is closed, the blocking parts on both sides pre-enclose the inner side of the annular body to structurally seal it;

[0008] Alternatively, the arc-shaped piece is provided with a blocking portion on one side of the opening, and during the closing process of the opening, the blocking portion reaches the arc-shaped piece on the other side in advance to enclose the inner side of the annular body to perform structural sealing.

[0009] As an improvement, the upper limit member is a plurality of blocking blocks arranged on the upper part of the lower limit member. When the opening is closed, the plurality of blocking blocks are arranged in a circle. The blocking blocks and the lower limit member are detachably connected through an easily disconnectable connection point or a socket.

[0010] As an improvement, a surrounding cavity is provided at the lower portion of the upper limit member, and the surrounding cavity is detachably mounted on the outer side of the lower limit member from the outside, so that the upper limit member is located above the lower limit member.

[0011] As an improvement, the inner side wall of the lower limit member includes a continuous inner upper section and an inner lower section. The inner upper section is surrounded by a size that is smaller at the top and larger at the bottom and gradually expands outward. The inner lower section is surrounded by a size that is larger at the top and smaller at the bottom and gradually contracts inward. The connection between the inner upper section and the inner lower section forms the bottom of the positioning groove with the largest size.

[0012] As an improvement, the size of the bottom of the inner lower section is smaller than the size of the top of the inner upper section, so that the bottom of the inner lower section forms a structural barrier, and the top of the inner upper section forms a structural opening after the upper limit piece is removed.

[0013] As an improvement, the inner wall of the upper limit member is formed into a size that is smaller at the top and larger at the bottom and expands outward gradually, and the size gradient of the inner wall and the inner upper section of the upper limit member continues up and down.

[0014] As an improvement, it also includes an inner limit seat, the inner limit seat includes a nail support seat body, a glans accommodating cavity, a nail groove and an inner positioning ring body, the nail support seat body has an inner cavity and an outer wall, the inner cavity is a glans accommodating cavity formed by extending inward at one end, a circle of nail grooves is arranged on the outer wall, and an inner positioning ring body cooperating with the annular body is formed on the outer wall between the glans accommodating cavity and the nail groove, the inner positioning ring body includes an upper section and a lower section, the upper section extends downward and outward from the end where the nail groove is located, and the upper section forms a cross-section with a size gradient of small at the top and large at the bottom, the lower section continues with the upper section and forms the outer end with the largest cross-section, the lower section extends downward and inward to form a cross-section with a size gradient of large at the top and small at the bottom and extends to the end where the glans accommodating cavity is opened, the upper section, the outer end and the lower section respectively correspond to the inner upper section and the inner lower section of the positioning groove bottom; the periphery of the end where the glans accommodating cavity is opened is structurally blocked by the bottom of the inner lower section, and the nail groove is structurally opened from the top of the inner upper section after the upper limit piece is disassembled, so that the nail groove area is exposed.

[0015] The beneficial effects of the present invention are as follows: by setting the annular body of the external fixing ring as a detachable upper limit piece and a lower limit piece, a good upper and lower limit structure can be enclosed when the partial locking structure is pre-fixed during the opening and closing process, and an adjustable space structure for accommodating the foreskin can be formed in cooperation with the inner limit seat. The enclosed state of the upper limit piece and the lower limit piece can prevent the inner limit seat from falling out, and the reserved space can ensure smooth adjustment of the foreskin. After completing the precise adjustment, the locking structure is further operated until the adjustable space between the lower limit piece and the inner limit seat disappears, thereby reliably fixing the foreskin. Removing the upper limit piece can allow the cutting and anastomosis area on the upper part of the inner limit seat to be completely exposed, which ensures that precise adjustment and reliable fixation are achieved at the same time as a whole, and does not block subsequent cutting and anastomosis of the foreskin.

[0025] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-9As shown, a specific embodiment of the foreskin adjustment limit device of the present invention is shown, which includes an annular body 1 with an opening 2. The opening 2 can be opened or closed by changing the shape of the annular body 1. The annular body 1 is provided with a locking structure 3 on both sides of the opening 2 that can be matched and locked to keep the opening 2 in a closed state. The annular body 1 includes an upper limit member 11 and a lower limit member 12. The upper limit member 11 is detachably arranged on the lower limit member 12, and the upper limit member 11 forms a structural blockage on the upper part of the lower limit member 12.

[0027] When the present invention is in use, the operator places the patient's glans penis in the glans accommodating cavity 02 of the inner limit seat 0, covers the inner positioning ring body 04 of the inner limit seat 0 with the foreskin, and the inner positioning ring body 04 is adapted to the inner wall of the lower limit piece 12. Then the opening 2 of the annular body 1 is closed, and the locking structure 3 is used to partially lock the foreskin for a preliminary limit. In this limit state, there is still a certain gap between the annular body 1 and the inner positioning ring body 04, which allows the foreskin to move smoothly. The operator can rely on this gap to easily adjust the inner and outer plates of the foreskin to the appropriate pre-cutting position to prevent the frenulum from entering the cutting area on the inner limit seat 0, thereby enabling precise adjustment. In this adjustment state, the upper and lower limit structures of the upper limit piece 11 and the lower limit piece 12 prevent the inner limit seat 0 from falling off from the upper or lower part of the annular body 1, so that during the adjustment process, the foreskin is always appropriately limited, ensuring the effectiveness and accuracy of the foreskin adjustment. After ensuring that the adjustment is precise and the frenulum is reliably protected, the locking structure 3 is further tightened, and the annular body 1 is continued to be closed until it is tightly embraced by the inner limit seat 0, and the foreskin is securely fixed by the lower limit member 12 and the inner positioning ring body 04, so that the foreskin cannot be displaced during the subsequent operation. Removing the upper limit member 11 does not affect the exposure of the upper cutting and anastomosis area of ​​the inner limit seat 0. After that, the lower limit member 12 and the inner limit seat 0 can be integrally installed into the circumcision anastomosis device to complete the subsequent cutting and anastomosis of the foreskin. The structure of the present invention as a whole ensures that precise adjustment and reliable fixation are achieved at the same time, ensuring good clinical use effects, reducing the risk of pulling damage to the foreskin and frenulum during adjustment and accidental cutting damage, reducing the rate of poor cutting of the inner and outer plates of the foreskin, and greatly improving the postoperative appearance and surgical effect.

[0028] As an improved specific implementation manner, the upper limit member 11 forms a structural barrier on the upper part of the lower limit member 12 , the inner diameter of which is smaller than the upper edge of the lower limit member 12 .

[0029] In one embodiment, the upper limit member 11 can be a structure formed on the upper part of the lower limit member 12 and having a size equivalent to the lower limit member 12. After forming a ring shape, it can well limit the foreskin and form a certain encirclement of the cut and anastomosis area on the upper part of the inner limit seat 0. In this embodiment, if Figure 3 、 5As shown in Figures 6, the radius of the upper limit member 11 is smaller than the upper edge of the lower limit member 12, which further improves the limiting effect on the foreskin and has a better upper and lower blocking effect on the structure.

[0030] As an improved specific embodiment, the upper limit member 11 is an arc-shaped piece arranged on the upper part of the lower limit member 12. After the opening 2 is closed, the arc-shaped piece is formed into a ring. The arc-shaped piece and the lower limit member 12 are detachably connected through an easily disconnected connection point 13.

[0031] like Figure 1 、 2 As shown in Figures 3 and 9, in the first embodiment, the arcuate piece and the lower stopper 12 can form a well-proportioned overall arcuate structure, uniformly enclosing and applying force to the inner foreskin. This helps to evenly distribute the foreskin in the space during adjustment, uniformly maintain the foreskin thickness after fixation, improve the effect of cutting and anastomosis, and ensure satisfactory postoperative appearance. The arcuate piece and the lower stopper 12 can be detachably connected via a plurality of spaced connection points 13. The connection points 13 can be implemented in a dot-shaped, sheet-shaped, or dotted-line-shaped structure, depending on whether they are easy to disconnect by applying force during actual use, or whether they can be cut or pried apart with surgical tools such as scissors or forceps.

[0032] As an improved embodiment, the arc-shaped piece is provided with relatively extending blocking portions 4 on both sides of the opening 2. The blocking portions 4 on both sides are staggered in height or inner and outer surfaces. When the opening 2 is closed, the blocking portions 4 on both sides pre-enclose the inner side of the annular body 1 to structurally seal it.

[0033] Alternatively, the arc-shaped piece is provided with a blocking portion 4 on one side of the opening 2 . During the closing process of the opening 2 , the blocking portion 4 reaches the arc-shaped piece on the other side in advance and encloses the inner side of the annular body 1 to structurally seal the opening 2 .

[0034] like Figure 1 、 2As shown in Figure 4, in the process of gradually closing the operating opening 2, the blocking parts 4 on both sides are surrounded (the blocking part 4 on one side and the arc-shaped piece on the other side are surrounded) to close the inner edge structure of the annular body 1. The so-called closure is to make the inner edge of the annular body 1 form a continuous space without a gap through the action of the blocking part 4. There is still a certain gap between the space and the foreskin tissue. Then the opening 2 is further reduced. Since there is no gap at this time, the foreskin tissue will not be squeezed, displaced or bulged, and will not affect the further closure of the annular body 1. Until it is closed into place, the annular body 1 becomes a circular ring. The locking structure 3 specifically arranged on the lower limit member 12 locks the overall shape of the annular body 1, and cooperates well with the inner positioning ring body 04 to position and fix the foreskin. The foreskin is evenly clamped and distributed in the appropriate space between the lower limit member 12 and the inner positioning ring body 04, ensuring the smoothness of the foreskin adjustment. By setting the blocking parts 4 on both sides (single-sided blocking part 4), the blocking parts 4 can close the gap earlier. After being staggered, the blocking parts 4 on both sides cross at different heights or inner and outer surfaces (the blocking part 4 on one side and the arc-shaped piece on the other side are staggered and crossed), blocking the foreskin on the inner side, and guiding the foreskin at the opening 2 to be evenly distributed on the inner side during the further closing process; the blocking parts 4 on both sides (single-sided blocking part 4) can be set to a reasonable length for pre-enclosure, and after realizing their function, they can be removed together with the disassembly of the upper limit member 11.

[0035] As an improved specific embodiment, the upper limit member 11 is a plurality of blocking blocks arranged on the upper part of the lower limit member 12. After the opening 2 is closed, the plurality of blocking blocks are arranged in a circle. The blocking blocks and the lower limit member 12 are detachably connected through an easily disconnectable connection point 13 or a socket.

[0036] like Figure 5 As shown, in the third embodiment, a circular arrangement formed by multiple blocking blocks can form an effective structural block on the circumference, preventing the inner limit seat 0 from falling out and assisting in limiting the foreskin. A good observation gap is left between the blocking blocks, which can provide the operator with an unobstructed field of view during the operation, facilitating more effective and accurate direct adjustment of the inner and outer plates of the foreskin and the frenulum. Each blocking block and the lower limit member 12 are detachably connected via an independent connection point 13. The connection point 13 can be implemented in a dot-shaped, sheet-shaped, or dotted-line shape, depending on whether it is easy to apply force to disconnect it during actual use, or whether it can be cut open with surgical tools such as scissors or vascular forceps. In another embodiment, the blocking block and the lower limit member 12 are detachably connected via a socket. In this way, the blocking block can be recycled after disinfection, which is more environmentally friendly and reduces costs.

[0037] As an improved specific implementation method, a surrounding cavity 111 is provided at the lower part of the upper limit member 11 , and the surrounding cavity 111 is detachably installed on the outer side of the lower limit member 12 from the outside, so that the upper limit member 11 is located above the lower limit member 12 .

[0038] like Figure 6 As shown, in the fourth embodiment, the enclosing cavity 111 is sleeved outside the lower stopper 12, positioning the upper stopper 11 above the lower stopper 12 to achieve a structural barrier function. The arrangement of the upper stopper 11 can refer to the first embodiment, forming a multi-piece arc-shaped structure. The enclosing cavity 111 can be installed and removed by inserting it into the lower stopper 12 to match its size, or by magnetic attraction for stable assembly and disassembly. This structure can also be recycled after disinfection, making it more environmentally friendly and reducing costs.

[0039] As an improved specific embodiment, the inner side wall of the lower limit member 12 includes a continuous inner upper section 121 and an inner lower section 122. The inner upper section 121 is formed into a size that is smaller at the top and larger at the bottom and gradually expands outward, and the inner lower section 122 is formed into a size that is larger at the top and smaller at the bottom and gradually contracts inward, and the connection between the inner upper section 121 and the inner lower section 122 forms the largest positioning groove bottom 123.

[0040] like Figure 3 、 9 As shown, the inner upper section 121 and the inner lower section 122 form a concave inner surface, which cooperates with the convex outer surface of the inner positioning ring body 04 to form an adaptation space. When the locking structure 3 is pre-fixed, this adaptation space is appropriately sized to accommodate the movement and adjustment of tissues of different foreskin thicknesses within the space. In addition, due to the structural obstruction of the upper limit member 11 and the inner lower section 122, the inner limit seat 0 will not fall out of the upper and lower positions of the annular body 1. When the foreskin is adjusted to the correct position, the locking structure 3 is further tightened. The shape formed by the inner upper section 121 and the inner lower section 122 and the largest positioning groove bottom 123, which is adapted to the inner positioning ring body 04, allows the lower limit member 12 to automatically find its position and fix the foreskin at the corresponding shape position of the inner positioning ring body 04. Then, the upper upper limit member 11 is removed to complete the adjustment and fixation of the foreskin. Such a design relies on the continuous concave surface to cooperate with the convex surface of the inner positioning ring body 04 to fix the foreskin, which increases the contact area with the foreskin and greatly reduces the local pressure on the foreskin, ensuring that the blood supply to the foreskin is not affected and reducing the risk of foreskin being compressed and damaged under previous technologies; at the same time, the increased compression area makes the foreskin fixation more reliable, and relies on the adaptive shape to automatically find the position and lock it during assembly, without the operator having to bother to observe and find the locking position, reducing the difficulty of operation.

[0041] As an improved specific embodiment, the size of the bottom of the inner lower section 122 is smaller than the size of the top of the inner upper section 121, so that the bottom of the inner lower section 122 forms a structural barrier, and the top of the inner upper section 121 forms a structural opening after the upper limit member 11 is removed.

[0042] like Figure 3 、 9 As shown, the cutting and fitting work requires that the cutting and fitting area on the inner limit seat 0 be fully exposed. Therefore, when designing the structure, the top size of the inner upper section 121 is designed to be larger and not higher than the plane of the cutting and fitting area, so that the structure can be opened after the upper limit member 11 is disassembled, so that the cutting and fitting area is fully exposed; and the bottom size of the inner lower section 122 is designed to be smaller, which can form a supporting state for the inner limit seat 0, facilitate the limitation between structures and prevent the inner limit seat 0 from falling out from under the annular body 1.

[0043] As an improved specific implementation manner, the inner wall of the upper limit member 11 is formed into a size that is smaller at the top and larger at the bottom and gradually expands outward, and the size gradient of the inner wall of the upper limit member 11 and the inner upper section 121 continues from top to bottom.

[0044] like Figure 1 、 2 As shown in Figures 3 and 9, the size enclosed by the upper limit member 11 and the inner upper section 121 forms a continuous state with the upper portion being smaller and the lower portion being larger, so that during the adjustment process, the inner limit seat 0 is effectively limited to prevent the inner limit seat 0 from falling off from the top of the annular body, resulting in failure of the adjustment operation.

[0045] As an improved specific embodiment, it also includes an inner limit seat 0, which includes a nail support body 01, a glans accommodating cavity 02, a nail groove 03 and an inner positioning ring body 04. The nail support body 01 has an inner cavity and an outer wall. The inner cavity is a glans accommodating cavity 02 formed by an inward depression at one end. A circle of nail grooves 03 is provided on the outer wall. An inner positioning ring body 04 that cooperates with the annular body 1 is formed on the outer wall between the glans accommodating cavity 02 and the nail groove 03. The inner positioning ring body 04 includes an upper section 041 and a lower section 042. The upper section 041 extends downward and outward from the end where the nail groove 03 is located, and the upper section 041 forms a small cross-section. The size of the lower part is gradually larger, and the lower section 042 is continuous with the upper section 041 to form the outer end 043 with the largest cross-sectional size. The lower section 042 extends downwardly and inwardly to form a cross-sectional size gradual change with a larger upper part and a smaller lower part and extends to the end where the glans accommodating cavity 02 is located. The upper section 041, the outer end 043, and the lower section 042 respectively correspond to the inner upper section 121 and the inner lower section 122 of the positioning groove bottom 123; the periphery of the end where the glans accommodating cavity 02 is located is structurally blocked by the bottom of the inner lower section 122, and the nail groove 03 is structurally opened by the top of the inner upper section 121 after the upper limit member 11 is disassembled, so that the nail groove 03 area is exposed.

[0046] like Figure 7、 8 As shown in Figure 9, the operator first places the concave anvil into the foreskin cavity, places the glans penis in the glans accommodating cavity 02 for protection and limitation, and covers the foreskin to the outer wall of the anvil body 01. As shown in the accompanying drawings, the anvil body 01 can be a shape that matches the glans penis. After the foreskin position is preliminarily adjusted, the annular body clamps the foreskin from the outside to complete the preliminary positioning; the outer size of the inner positioning ring body 04 forms a state of changing from small to large and then to small, that is, the structure of the upper section 041 and the lower section 042. Its gradual size change cooperates with the lower limit member 12 to accommodate the foreskin in a roughly arc-shaped space, which is convenient for the operator to adjust the foreskin smoothly, stably and accurately, until the foreskin position is adjusted into place, and the annular body 1 continues to close to complete the assembly of the lower limit member 12 and the inner positioning ring body 04, thereby firmly clamping the foreskin to complete the fixation. The specific structural improvement of the inner positioning ring body 04 cooperates with the structure of the upper limit piece and the lower limit piece of the annular body to facilitate smooth and stable adjustment of the foreskin, without causing the inner positioning ring body 04 to fall out, resulting in adjustment failure. The structural design of the inner positioning ring body 04 changes from small to large and then to small, and can firmly fix the foreskin after assembly with the lower limit piece 12. The specific outer end 43 is the position with the largest size, which can be well limited in the positioning groove bottom 123 corresponding to the lower limit piece 12. When the lower limit piece is completed to lock and fix the foreskin, after the upper limit piece is removed, it can still maintain good limitation and will not fall out from the lower limit piece. In the process of closing the annular body, it can automatically find the matching position of the lower limit piece to fix the foreskin. Overall, this design can not only ensure the smoothness and stability of the foreskin adjustment, but also achieve accurate positioning and reliable fixation of the foreskin cutting and anastomosis. Furthermore, the perimeter of the opening of the glans accommodating cavity 02 is structurally blocked by the bottom of the inner lower section 122, providing excellent structural support and positioning during foreskin adjustment. The nail groove 03 is exposed at the top of the inner upper section 121 after the upper limit member 11 is removed. The upper surface area where the nail groove 03 is located serves as the cutting and anastomosis area, and its good exposure ensures smooth foreskin cutting and anastomosis.

[0047] As an improved specific implementation method, the upper section 041 is longer than the lower section 042 , so that the outer end 043 is formed at a lower position in the inner positioning ring body 04 .

[0048] like Figure 8 、 9As shown, the outer end 043 is formed in a lower position in the inner positioning ring body 04. When the annular body 1 and the inner limit seat 0 are adapted and fixed, the outer end 043 is downwardly accommodated in the groove position at the lower part of the annular body 1, thereby giving the foreskin and the frenulum a downward extrusion limit. Since the foreskin to be cut needs to be tied upward to the pull rod of the inner limit seat 0 with a binding strap before foreskin cutting, the design of the downward extrusion limit can well resist the upward pulling force on the foreskin during binding, avoid the upward displacement of the foreskin and frenulum after adjustment and fixation, and further ensure the reliable fixation of the foreskin and the safety of cutting.

[0049] As an improved embodiment, the annular body 1 can be configured into a multi-segment positioning arc structure as required, such as Figure 1 、 2 Figures 4, 5, and 6 illustrate a two-stage structure. During implementation, the design can be further expanded to include more stages, as needed, to meet the requirements for opening and operating freedom, and to accommodate the operating habits of different surgeons. By rotating the joints of the multi-stage positioning arc, the shape of the annular body 1 changes, opening or closing the opening 2. The multi-stage positioning arc can be manufactured from elastic or non-deformable materials as needed. Different implementations can be tailored to the surgeon's operating habits and the patient's specific conditions, adapting to varying needs.

[0050] Alternatively, the annular body 1 may be a flexible, one-piece structure, whereby the annular body 1 elastically changes shape to open or close the opening 2. This embodiment is not shown in the accompanying drawings. The one-piece structure primarily utilizes an elastic material to form the annular body 1, which uses its own elasticity to create a shape change to open or close the opening 2. This structure is simpler to manufacture, and different embodiments can be selected based on the surgeon's operating habits and the patient's specific conditions to meet different needs.

[0051] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
