Description

Technical Field

[0001] This invention relates to the field of stapler technology, and more specifically, to a rotary locking disposable circumcision stapler and its application method. Background Technology

[0002] The circumcision stapler is a specialized medical device used in clinical circumcision surgery. Its core function is to replace the "scissors cutting and needle and thread suturing" steps in traditional surgery. Through mechanical structure, it achieves precise removal of the foreskin and automatic anastomosis of the wound. It has advantages such as simple operation, short operation time, less bleeding, and aesthetic healing, and has become one of the mainstream tools for circumcision surgery in clinical practice.

[0003] Among them, patent publication number CN102068297A discloses a disposable circumcision stapler. This circumcision stapler includes an outer ring and an inner ring. The outer ring has a blade with microstructures for preventing skin adhesion. The outer side of the inner ring has a rubber gasket with microstructures for preventing skin adhesion. The upper and lower end faces of the inner ring have raised grooves with microstructures for preventing skin adhesion. These microstructures can be patterned, formed by a plurality of recessed grooves and raised grooves. When in use, the structure can reduce the thickness of the connection by having an elastic groove in at least one of the first and second connecting blocks, which facilitates elastic deformation. However, while a single elastic groove can reduce the thickness of the connection, it can also easily cause unstable locking and fail to achieve the function of pressing when the circumcision device is fastened, which can easily lead to incomplete circumcision. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spin-locking disposable circumcision stapler, which aims to solve the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a rotary locking disposable circumcision stapler, comprising a first connecting part and a second connecting part, wherein the first connecting part and the second connecting part are disposed opposite to each other and can be rotated or pressed relative to each other; A first locking block is fixedly provided at one end of the first connecting part, and a pad is fixedly connected to the bottom of the first locking block, forming a locking cavity between the pad and the first locking block; A second locking block is fixedly provided at one end of the second connecting part, and a slanted rotary groove is provided at the top of the pad. A slanted rotary locking block is fixedly provided at the bottom of the second locking block. The slanted rotary locking block cooperates with the slanted rotary groove to achieve rotary locking.

[0006] Optionally, in one possible implementation, the second locking block extends into the locking cavity and is arranged side by side with the first locking block. The first locking block and the second locking block are respectively provided with a locking tooth structure on their opposite sides, and the locking tooth structure engages with each other to achieve axial locking. Optionally, in one possible implementation, the inner walls of the first connecting part and the second connecting part are respectively provided with arc-shaped cutters, the cutting edges of the cutters facing the inside of the stapler, and the ends of the first connecting part and the second connecting part away from the locking block are respectively provided with rotating structures. The two rotating structures are stacked and can be inserted into the rotating drive component. The upper surface of the second locking block is provided with a through hole, which is used to separate the first connecting part and the second connecting part.

[0007] This invention also provides a rotary locking disposable circumcision stapler, comprising a sleeved outer ring and an inner ring. The outer ring includes a first connecting portion and a second connecting portion, with one end of the first connecting portion and the second connecting portion rotatably connected, and the other end connected by a locking member. The locking member includes a first locking member and a second locking member, with the first locking member clamping the second locking member in the middle and having a fastening member for tight engagement. The arrangement of the first locking member clamping the second locking member in the middle and having a fastening member for tight engagement is to reliably lock the second locking member, thereby reliably locking and securing the opening structure.

[0008] Preferably, the fastening element includes a first fastening element located on the first locking element and a second fastening element located on the second locking element. The first fastening element and the second fastening element fasten each other to ensure a tight fit between the first locking element and the second locking element. The mutual fastening of the first fastening element and the second fastening element ensures a tight fit between the first locking element and the second locking element, thereby reliably fastening and locking the opening structure.

[0009] Preferably, the first locking member includes a first clamping member and a second clamping member, which are located on both sides of the first fastening member. The arrangement of the first and second clamping members on both sides of the first fastening member is to restrict the second fastening member's freedom of movement when the first and second fastening members are engaged and fastened together. Through the tight fastening of the first and second locking members and the obstruction on both sides of the first and second clamping members, multiple degrees of freedom are restricted, thereby better and more reliably locking the opening structure.

[0010] Preferably, the first and second fastening components are serrated or snap-fit ​​structures. The provision that the first and second fastening components are serrated or snap-fit ​​structures is a preferred option, not a restrictive requirement.

[0011] Preferably, the second locking member has a through-hole structure. The second locking member has a through-hole that facilitates the separation of the first and second locking members. This allows for direct separation of the first and second locking members during postoperative procedures using a wrench or other means through the through-hole, thereby opening the outer ring structure and preventing injury to the wound. Since these are disposable, the through-hole can be easily opened with a wrench; it can even be damaged, as long as it can be quickly removed from the injured area.

[0012] The present invention also provides a method for applying the above-mentioned spin-locking disposable circumcision stapler, the specific steps of which are as follows: (1) Initial positioning: Place the foreskin tissue between the outer ring and the inner ring, and rotate it to connect one end of the first connecting part and the second connecting part, while locking the other end through step (2) or step (3); (2) Spinning and locking: The second locking block extends into the locking cavity formed by the first locking block and the pad. The rotating structure drives the second connecting part to move relative to the first connecting part, so that the inclined spin locking block slides along the inclined spin groove on the pad, converting the rotational motion into linear pressing motion to achieve progressive locking force. When the inclined spin locking block moves to the end of the inclined spin groove, the locking tooth structure of the first locking block and the second locking block engages with each other to achieve locking. (3) Engagement and locking: The second locking member moves to the middle of the first locking member and is tightly engaged by the fastening member to achieve locking; (4) Postoperative separation: The foreskin tissue, which is tightly clamped between the outer ring and the inner ring, undergoes necrosis due to blood loss after a period of time, thus completing the foreskin cutting; then, external force is applied through the through hole to separate the first connection part from the second connection part, thereby opening the outer ring and avoiding damage to the wound to complete the postoperative separation.

[0013] The technical effects and advantages of this invention are as follows: By setting up a cooperative structure between the inclined rotary groove and the inclined rotary locking block, the rotational motion of the second connecting part is transformed into a smooth linear pressing motion. Compared with simple elastic buckles or one-time pressing, this rotary locking method provides a progressive locking force, allowing doctors to better perceive the locking force and avoiding incomplete locking, thus greatly improving the controllability and reliability of the locking process.

[0014] The first and second locking blocks achieve final locking through a meshing tooth structure. After being clamped in place by oblique rotation, this structure forms a strong mechanical interlock, effectively resisting axial reaction force and preventing accidental loosening of the stapler due to tissue tension rebound during or after cutting, thus ensuring stability throughout the entire surgical procedure.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0026] like Figures 1 to 4 , Figure 9This illustration shows an embodiment of a rotary locking disposable circumcision stapler and its application method. The rotary locking disposable circumcision stapler is used to achieve rapid and precise excision and anastomosis during circumcision surgery. It includes a sleeved outer ring 13 and an inner ring 11. The outer ring 13 includes a first connecting part 1 and a second connecting part 2, which are oppositely arranged and can rotate or press against each other. A first locking block 3 is fixedly provided at one end of the first connecting part 1, and a pad 4 is fixedly connected to the bottom of the first locking block 3, forming a locking cavity between the pad 4 and the first locking block 3. A second locking block 6 is fixedly provided at one end of the second connecting part 2, and a slanted rotary groove 5 is provided at the top of the pad 4. A slanted rotary locking block 10 is fixedly provided at the bottom of the second locking block 6, and the slanted rotary locking block 10 cooperates with the slanted rotary groove 5 to achieve rotary locking. The outer ring 13 is sleeved over the inner ring 11, and a gap for clamping tissue is provided between the outer ring 13 and the inner ring 11.

[0027] The second locking block 6 extends into the locking cavity and engages with the first locking block 3 for locking.

[0028] In addition, the first locking block 3 and the second locking block 6 are respectively provided with a locking tooth structure on their opposite sides, and the locking tooth structure meshes with each other to achieve radial locking.

[0029] The inner walls of the first connecting part 1 and the second connecting part 2 are respectively provided with arc-shaped cutters 7, and the cutting edge of the cutter 7 faces the inside of the anastomosis device.

[0030] In addition, the first connecting part 1 and the second connecting part 2 are rotatably connected away from the locking block via the rotating structure 8.

[0031] The upper surface of the second locking block 6 is provided with a through hole 9, which is used to separate the first connecting part 1 and the second connecting part 2.

[0032] Specifically, the first connecting part 1 and the second connecting part 2 are arranged opposite to each other via a rotating structure 8, allowing the doctor to hold or connect to a drive device for rotational operation. A first locking block 3 is fixedly installed at one end of the first connecting part 1, and a pad 4 is welded or integrally formed at its bottom, forming a locking cavity between the pad 4 and the first locking block 3.

[0033] A second locking block 6 is fixedly installed at one end of the second connecting part 2, and the second locking block 6 extends into the locking cavity. The top of the pad 4 is provided with an oblique rotary groove 5, and the bottom of the second locking block 6 is provided with an oblique rotary locking block 10 that cooperates with it. When the first connecting part 1 and the second connecting part 2 rotate relative to each other, the oblique rotary locking block 10 moves along the oblique rotary groove 5 to achieve rotary locking.

[0034] To further enhance locking stability, the first locking block 3 and the second locking block 6 are provided with interlocking tooth structures on their opposite sides, which can further lock in the axial direction.

[0035] The stapler has an arc-shaped cutter 7 on its inner side, with its blade facing inward, used to simultaneously perform circumcision during locking. The upper surface of the second locking block 6 has a through hole 9. This structure is designed to separate the first connecting part 1 and the second connecting part 2 by applying force after the surgery. This primarily provides a point of force application. In this embodiment, a through hole is used, which facilitates operation with an external wrench or other structure and reduces the overall weight of the disposable circumcision stapler. Additionally, the second connecting part 2 has a protrusion 41, which acts as a reinforcing rib, increasing strength; it also provides a gap between the protrusion and the contact surface for easy removal.

[0036] The specific working principle is as follows: During the surgery, the foreskin tissue is placed between the first connecting part 1 and the second connecting part 2. The rotating structure 8 drives the second connecting part 2 to rotate relative to the first connecting part 1. The oblique rotating locking block 10 moves along the oblique rotating groove 5, gradually pressing the tissue until it is completely locked. During this process, the cutter 7 completes the circumferential cutting operation, and the locking tooth structure ensures that it will not accidentally loosen after locking.

[0037] The present invention also provides a method for applying the above-mentioned spin-locking disposable circumcision stapler, the specific steps of which are as follows: (1) Initial positioning: Place the foreskin tissue between the outer ring 13 and the inner ring 11, and rotate one end of the first connecting part 1 to the second connecting part 2, while the other end is locked in the manner of step 2; (2) Spinning and locking: The second locking block 6 extends into the locking cavity formed by the first locking block 3 and the pad 4. The rotating structure 8 drives the second connecting part 2 to move relative to the first connecting part 1, so that the inclined spin locking block 10 slides along the inclined spin groove 5 on the pad 4, converting the rotational motion into linear pressing motion to achieve progressive locking force; when the inclined spin locking block 10 moves to the end of the inclined spin groove 5, the locking tooth structure of the first locking block 3 and the second locking block 6 engages with each other to achieve locking; (3) Postoperative separation: The foreskin tissue tightly clamped between the outer ring 13 and the inner ring 11 undergoes blood loss and necrosis after a period of time, thus completing the foreskin cutting; then, external force is applied through the through hole 9 to separate the first connecting part 1 from the second connecting part 2, thereby opening the outer ring 13 and avoiding damage to the wound to complete the postoperative separation.

[0038] Optionally, in step (2), the spinning locking process consists of the following steps: (1) Pre-tightening stage: Slowly rotate the rotating structure 8 to make the oblique rotating locking block 10 move along the initial section of the oblique rotating groove 5, the outer ring 13 and the inner ring 11 press the foreskin tissue, and the alignment status is detected by the partial engagement of the tooth structure; (2) Main locking stage: accelerate the rotation until the inclined locking block 10 enters the inclined part of the inclined groove 5, and the linear clamping force increases evenly; (3) Verification stage: When the locking teeth are fully engaged, the locking can be confirmed.

[0039] Optionally, in step (4), an external wrench or other structure is inserted through the through hole to apply a controllable pulling force along the axial direction to the through hole 9, causing the second locking block 6 to undergo elastic deformation, disrupting the engagement state of the locking tooth structure, and separating the first connecting part from the second connecting part. It should be noted that the circumcision operation is generally completed within one month after the surgery, that is, when the foreskin tissue sandwiched between the inner and outer rings has lost blood and become necrotic, the circumcision is considered complete.

[0040] In addition, it includes a locking force calibration step: the theoretical clamping stroke is calculated based on the inclined angle of the inclined groove 5, and the formula is: stroke = rotation angle × inclined groove slope, where the slope is determined by the geometric parameters of the inclined groove 5; in actual operation, the clamping force is calibrated in real time by the rotation angle feedback of the rotating structure 8 to ensure that the clamping force matches the tissue thickness. Example 2

[0041] like Figures 5 to 9 The illustration shows a second embodiment of a rotary locking disposable circumcision stapler and its application method. This embodiment is similar to the first embodiment, except that it includes a sleeved outer ring 13 and an inner ring 11. The outer ring 13 includes a first connecting part 1 and a second connecting part 2. One end of the first connecting part 1 and the second connecting part 2 are rotatably connected by a rotating structure 8, and the other end is connected by a locking member 12. The locking member 12 includes a first locking member 121 and a second locking member 122. The first locking member 121 clamps the second locking member 122 in the middle and is provided with a fastening member 123 for tight engagement. The arrangement of the first locking member clamping the second locking member in the middle and providing a fastening member for tight engagement is to reliably lock the second locking member, thereby reliably engaging and locking the opening structure.

[0042] The fastening member 123 includes a first fastening member 124 located on the first locking member 121 and a second fastening member 125 located on the second locking member 122. The first fastening member 124 and the second fastening member 125 are fastened together, so that the first locking member 121 and the second locking member 122 are tightly fastened together. The first fastening member and the second fastening member are fastened together, so that the first locking member and the second locking member are tightly fastened together, thereby reliably fastening and locking the opening structure.

[0043] In addition, the first locking member 121 is provided with a first clamping member 126 and a second clamping member 127, which are located on both sides of the first fastening member 124. The arrangement of the first clamping member and the second clamping member on both sides of the first fastening member is so that when the first fastening member and the second fastening member are fastened together, the first clamping member and the second clamping member on both sides clamp the second fastening member in the middle to restrict its degree of freedom. Through the tight fastening of the first locking member and the second locking member and the blocking on both sides of the first clamping member and the second clamping member, the degree of freedom in multiple directions is restricted, thereby better and more reliably fastening and locking the opening structure.

[0044] The second locking component features a through-hole structure 8. This through-hole facilitates the separation of the first and second locking components during postoperative separation. A wrench or other tool can be inserted through the through-hole to separate the first and second locking components, thereby opening the outer ring structure and preventing injury to the wound. Since these are disposable, the through-hole can be easily opened with a wrench; it can even be damaged, as long as it can be quickly removed from the injured area.

[0045] The application method of the rotary locking disposable circumcision stapler in this embodiment is similar to that in embodiment one. The difference is that in step (3), this embodiment uses meshing locking: the second locking member 122 moves to the middle of the first locking member 121 and is tightly fastened by the fastening member 243 to achieve locking.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
