Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a circumcision device that is easy to fix. Background Technology

[0002] Phimosis or paraphimosis in men is one of the root causes of male urinary tract infections and sexually transmitted diseases. Circumcision, as a common surgical treatment for phimosis or paraphimosis, is widely used in clinical practice. A circumcision device is the core medical instrument used in circumcision surgery; it precisely removes excess foreskin through a circular cutting device, simultaneously completing anastomosis, fixation, and hemostasis.

[0003] Traditional circumcision devices have many limitations in clinical application, especially in the alignment of the inner and outer rings. The lack of a precise alignment and positioning structure makes it difficult to quickly and accurately align the surgical ends of the inner and outer rings, thus failing to form a neat circumferential cut surface. Secondly, in terms of fixing the circumcision device to the penis, clamps or flexible bandages are often used, which not only pose a risk of insecure fixation and misalignment, but may also cause tissue damage due to uneven local pressure, resulting in patient pain or infection risks.

[0004] A search revealed Chinese invention patent CN107874816B, which discloses a precise circumcision stapler. The stapler includes a foreskin fixing ring and a circumcision suture section. The foreskin fixing ring comprises an inner ring and an outer ring. The inner ring is used to position the foreskin cutting length, and the outer ring is used to fix the everted foreskin covering the inner ring. The circumcision suture section and the outer ring are detachably connected. The circumcision suture section is used to suture the cut foreskin. This stapler can achieve a single cut while accurately positioning the foreskin cutting length, effectively reducing postoperative pain and the risk of infection while ensuring a cosmetically pleasing incision. Summary of the Invention

[0005] The purpose of this invention is to provide a circumcision device that is easy to fix, so as to solve the problems mentioned in the background art.

[0006] The main design concept of this invention is as follows: The circumcision device is the core medical instrument for circumcision surgery. Existing circumcision devices have many problems, especially the difficulty in quickly and accurately aligning the inner and outer rings, making it impossible to form a neat circumferential surface; secondly, the fixation structure between the circumcision device and the penis has problems with insecure fixation and easy tissue damage; finally, the distance between the inner and outer rings cannot be adjusted, making it difficult for the foreskin to pass through and be removed when fixing the foreskin, which easily damages the tissue, and there are problems with insecure fixation and easy misalignment.

[0007] To address the aforementioned problems, this invention proposes a circumcision device that facilitates fixation. First, a circumcision alignment mechanism is set on the inner and outer rings. Specifically, a guide frame is set on the inner ring, and a positioning frame is connected to the outer ring. Through the cooperation of the guide frame and the positioning frame, as well as the locking mechanism, the surgical circumcision surfaces of the inner and outer rings are quickly and accurately aligned and fixed.

[0008] Secondly, a circumcision fixation mechanism is set at the bottom of the outer ring, including a ring-shaped elastic clamping member. The clamping member is driven by a clamping drive to expand and contract, thereby clamping or releasing the penis, thus fixing the circumcision device to the penis for the next step of surgery. The ring-shaped elastic clamping member can provide sufficient radial clamping force to prevent the circumcision device from moving.

[0009] Finally, a foreskin fixation mechanism is designed between the inner and outer rings, including two movable semi-rings. The two movable semi-rings can move radially towards or away from each other between the inner and outer rings to change the distance between them and the outer wall of the inner ring. They cooperate with the inner ring to clamp or loosen the foreskin, preventing the foreskin from moving or shifting so that circumcision can be performed.

[0010] To achieve the above objectives, the present invention provides the following technical solution: A convenient circumcision device includes an inner ring and an outer ring, the inner ring being placed inside the foreskin and the outer ring being fitted over the foreskin, and further includes: A ring-cutting alignment mechanism is installed on the inner and outer rings to align the upper end face of the outer ring with the upper end face of the inner ring. The circumferential clamping mechanism, located at the bottom of the outer ring, is used to clamp or release the penis circumferentially.

[0011] More preferably, the circumferential alignment mechanism includes: The guide frame has a U-shaped structure, with its two ends connected to the upper end face of the inner ring. The outer surfaces of the two vertical sections of the guide frame are provided with grooves along their axial direction. The positioning frame is set at the bottom of the outer ring and cooperates with the two sliding grooves to align the upper surface of the outer ring with the upper surface of the inner ring.

[0012] More preferably, the positioning frame includes: A support ring is located at the bottom end of the outer ring; There are two portal frames. One end of each portal frame is symmetrically connected to both sides of the support ring. The other end of each portal frame is equipped with a slider, which slides along two grooves.

[0013] In order to lock the aligned outer and inner rings, preferably, the lower ends of both slides are provided with locking holes, and the tops of both sliders are provided with locking pins that cooperate with the locking holes.

[0014] To secure the circumcision device to the penis for circumcision surgery, more preferably, the circumcision fixation mechanism includes: The clamping element is an elastic ring structure located at the bottom end of the support ring, and the outer wall of the clamping element is connected to two connecting pipes; The clamping drive, connected to two connecting pipes, is used to drive the clamping element to expand or contract to clamp or release the penis.

[0015] More preferably, the clamping drive includes two screws, which are respectively threaded through and connected to the other end of the two portal frames of the positioning frame. A piston rod is connected to one bottom end of the screw, and the piston rod slides inside the connecting tube.

[0016] In order to clamp the foreskin from both the inside and outside along the circumference and prevent the foreskin from moving or shifting under external force during the operation, causing uneven circumferential incision and affecting the suturing and surgical quality, the foreskin circumcision device further preferably includes a foreskin fixing mechanism, which is sleeved outside the inner ring and cooperates with the inner ring to clamp or loosen the foreskin along the circumference.

[0017] More preferably, the foreskin fixing mechanism includes: Two movable semi-rings are installed inside the outer ring and outside the inner ring, with the upper end faces of the two movable semi-rings flush with the upper end face of the outer ring. A semi-ring drive assembly, connected to two movable semi-rings, is used to drive the two movable semi-rings to move radially toward or away from each other along the inner ring.

[0018] More preferably, the semi-ring drive assembly includes: The guide block is located at the center of the outer wall of the movable semi-ring; A magnetic rod, one end of which is connected to the free end of a guide block; A wedge block is disposed between the screw and the piston rod. The wedge block contacts the other end of the magnetic rod. The side wall of the wedge block that contacts the magnetic rod has an inclination angle, and the side wall is magnetically attracted to the magnetic rod.

[0019] To facilitate wound suturing after circumcision, more preferably, the upper end of the outer ring is provided with a plurality of first suture holes along its circumference, the two movable half-rings are provided with second suture holes corresponding to the first suture holes, and the inner ring is provided with third suture holes corresponding to the second suture holes.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention provides a circumcision device that is easy to fix.

The aligned inner and outer ring positions are locked by a locking mechanism.

[0021] 2. The present invention provides a circumcision device that is easy to fix. The circumcision device is relatively fixed to the penis by means of a ring-shaped elastic clamping member. The penis is clamped and released by driving the expansion and contraction of the clamping member. The clamping member can not only avoid damaging the tissue, but also provide sufficient radial clamping force and maintain axial compliance to avoid compressing the urethra.

[0022] 3. The present invention provides a circumcision device that is easy to fix, wherein two movable half-rings are added between the inner and outer rings. The two movable half-rings can move radially between the inner and outer rings and cooperate with the inner ring to clamp or loosen the foreskin, so as to prevent the foreskin from moving or misaligning in order to perform circumcision surgery.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] Example 1 like Figures 1-19 As shown, this embodiment provides a circumcision device that is easy to fix, including an inner ring 1 and an outer ring 2. The inner ring 1 is placed inside the foreskin, and the outer ring 2 is sleeved outside the foreskin. It also includes: a circumcision alignment mechanism, which is disposed on the inner ring 1 and the outer ring 2, for aligning the upper end face of the outer ring 2 with the upper end face of the inner ring 1; and a circumcision fixing mechanism, which is disposed at the bottom end of the outer ring 2, for clamping or releasing the penis in the circumferential direction.

[0027] In one specific implementation, during the surgery, inner ring 1 is placed on the glans and inside the foreskin, retracting the foreskin. Outer ring 2 is placed outside the foreskin. Inner ring 1 and outer ring 2 are coaxially arranged and work together to clamp the foreskin between the inner and outer rings, forming a neat circumferential cut surface for the next step of the surgery. A circumcision alignment mechanism is located on inner ring 1 and outer ring 2. Using the position of inner ring 1 as a reference, it moves outer ring 2, quickly and accurately aligning the upper end face of outer ring 2 axially with the upper end face of inner ring 1, forming a neat circumferential cut surface. The circumcision fixation mechanism is an overall ring-shaped structure located at the bottom of outer ring 2, fitted onto the penis. It applies radial clamping force along the circumference of the penis, achieving relative fixation of the circumcision device to the penis, facilitating the circumcision surgery. Both inner ring 1 and outer ring 2 are made of medical-grade polycarbonate material to prevent tissue damage.

[0028] Example 2 like Figures 1-19 As shown, based on Embodiment 1, this embodiment provides a circumcision device that is easy to fix. The circumcision alignment mechanism includes: a guide frame 31, which is a U-shaped structure, with its two ends connected to the upper end face of the inner ring 1. The outer surfaces of the two vertical sections of the guide frame 31 are provided with grooves 311 along their axial direction; and a positioning frame 32, which is set at the bottom of the outer ring 2 and cooperates with the two grooves 311 to align the upper end face of the outer ring 2 with the upper end face of the inner ring 1.

[0029] In one specific implementation, the guide frame 31 is a U-shaped frame structure, with the two ends of the U-shape connected to the upper end face of the inner ring 1. Preferably, the cross-section of the guide frame 31 is arranged perpendicular to the end face of the inner ring 1, and the two connection points between the guide frame 31 and the inner ring 1 are the intersection points of the diameter of the inner ring 1 and the outer circumference, so as to ensure the stability of the connection between the guide frame 31 and the inner ring 1.

[0030] The crossbeam section of the guide frame 31 serves as a handle, featuring anti-slip textures for easy gripping and placement of the inner ring within the cover. The outer surfaces of both vertical sections of the guide frame 31 are symmetrically arranged with grooves 311 along the axial direction of the vertical section. The grooves 311 are arc-shaped, starting from the top of the vertical section and extending downwards along the axial direction of the vertical section, i.e., from the inflection point between the vertical and horizontal sections.

[0031] One end of the positioning frame 32 is set at the bottom of the outer ring 2, and the other end slides from top to bottom along the two sliding grooves 311 to quickly and accurately align the upper surface of the outer ring 2 with the upper surface of the inner ring 1, and clamp the foreskin to form a neat circumferential surface.

[0032] The positioning frame 32 includes: a support ring 321, which is disposed at the bottom end of the outer ring 2; and two gate-shaped frames 322, one end of which is symmetrically connected to both sides of the support ring 321, and the other end of each gate-shaped frame 322 is provided with a slider 323, which slides along two slide grooves 311 respectively.

[0033] In one specific implementation, the support ring 321 has a ring-shaped structure. Preferably, the cross-sectional dimensions of the support ring 321 are consistent with those of the outer ring 2. The support ring 321 and the outer ring 2 are coaxially arranged. The support ring 321 is made of medical-grade silicone to prevent tissue damage when in contact with tissue.

[0034] Two portal frames 322 are symmetrically arranged on both sides of the support ring 321, that is, at both ends along the diameter direction of the interface of the support ring 321. Preferably, the two portal frames 322 are arranged perpendicular to the support ring 321 to ensure the stability of the connection.

[0035] The two portal frames 322 and the guide frame 31 are located on the same plane, and the other ends of the two portal frames 322 are arranged perpendicularly to the slide groove 311. The other ends of the two portal frames 322 are respectively provided with sliders 323, and the two sliders 323 slide up and down along the two slide grooves 311 to align the upper end face of the outer ring 2 with the upper end face of the inner ring 1.

[0036] Both slides 311 have locking holes 312 at their lower ends, and both sliders 323 have locking pins 324 at their tops that mate with the locking holes 312. Each locking pin 324 includes a spring and a ball bearing. Each slider 323 has an open cavity. One end of the spring is fixedly mounted on the bottom wall of the cavity and extends and retracts axially along the other end of the portal frame 322. The other end of the spring is fixedly connected to a ball bearing, which is fitted into the locking hole 312.

[0037] When the slider 323 drives the locking pin 324 to slide to the locking hole 312 of the slide groove 311, the spring pushes the ball into the locking hole 312, locking the position of the positioning frame 32 and the guide frame 31, that is, fixing the relative position of the outer ring 2 and the inner ring 1.

[0038] According to the structural design of the ring cutter, when the locking pin 324 engages with the locking hole 312 to lock the positioning frame 32 and the guide frame 31 in position, the upper surface of the outer ring 2 is precisely flush with the upper surface of the inner ring 1, achieving rapid and precise alignment and locking of the upper surfaces of the inner and outer rings. This eliminates the need for repeatedly trying to slide the positioning frame 32 up and down, or manually aligning the upper surfaces of the inner and outer rings through experience or visual observation.

[0039] When the circumcision device needs to be removed after the surgery, pull the positioning frame 32 upward to separate the locking pin 324 from the locking hole 312 so that the positioning frame 32 and the outer ring 2 can be slowly removed, and then the guide frame 31 and the inner ring 1 can be removed in sequence to complete the surgical procedure.

[0040] Example 3 like Figures 1-19 As shown, based on Embodiment 2, this embodiment provides a circumcision device that is easy to fix. The circumcision fixing mechanism includes: a clamping member 41, which is an elastic ring structure and is disposed at the bottom end of the support ring 321. The outer side wall of the clamping member 41 is connected to two connecting pipes 411; a clamping drive member, which is connected to the two connecting pipes 411 and is used to drive the clamping member 41 to expand or contract to clamp or release the penis.

[0041] In one specific implementation, the clamping member 41 is an elastic ring-shaped structure, such as an airbag, a water bag, or other components that can change their internal volume. In this embodiment, an airbag is used as the clamping member 41, and it is made of medical-grade silicone to prevent tissue damage.

[0042] In its natural state, the clamping member 41 has the same cross-sectional dimensions as the support ring 321. The clamping member 41 is located at the bottom end of the support ring 321, and the two are arranged coaxially. In use, the clamping member 41 is fitted onto the middle of the penis.

[0043] Two connecting pipes 411 are symmetrically arranged on both sides of the clamping member 41, that is, two connecting pipes 411 are arranged at both ends along the diameter direction of the clamping member 41. One end of the connecting pipe 411 is sealed to the clamping member 41 to ensure that gas does not escape. Preferably, the connecting pipe 411 has an L-shaped structure, and its horizontal free end is connected to the clamping member 41. One end of the two portal frames 322 has a through hole vertically symmetrically opened at one end. The free end of the vertical section of the L-shaped structure passes through the through hole and is connected to the through hole so as to securely connect the clamping member 41 to the bottom end of the positioning frame 32.

[0044] The clamping drive is connected to two connecting pipes 411, specifically to the free end of the vertical section of the connecting pipe 411. By changing the internal volume and pressure of the clamping member 41 through the clamping drive and the connecting pipes 411, the clamping member 41 expands or contracts, thereby radially clamping or releasing the penis along the circumference of the penis.

[0045] The clamping drive includes two screws 421, which are respectively threaded through and connected to the other end of the two portal frames 322 of the positioning frame 32. A piston rod 422 is connected to the bottom end of the screw 421, and the piston rod 422 slides in the connecting pipe 411.

[0046] In one specific implementation, threaded through holes are vertically and symmetrically provided at the other ends of the two portal frames 322. Two screws 421 pass through the two threaded through holes respectively and engage with the threads inside the threaded through holes. Preferably, the screws 421 are arranged parallel to the axis of the crossbeam section of the portal frame 322 to enhance the stability of the circumferential fixing mechanism.

[0047] A piston rod 422 is fixedly connected to one bottom end of the screw 421, and the other end of the piston rod 422 slides within the vertical section of the connecting pipe 411. The piston rod 422 is sealed to the connecting pipe 411 to ensure that gas does not leak out. A knob is fixedly connected to one top end of the screw 421.

[0048] When in use, hold the two knobs and rotate them clockwise or counterclockwise simultaneously to drive the screw 421 to rotate downward along the threaded through hole, which in turn drives the piston rod 422 to rotate downward along the connecting pipe 411, thereby reducing the internal volume of the clamping member 41 and increasing the internal pressure, so that the clamping member 41 gradually expands and clamps the penis.

[0049] When it is necessary to loosen the ring-cutting fixing mechanism, rotate the knob in the opposite direction to drive the screw 421 to rotate upward along the threaded through hole, which in turn drives the piston rod 422 to rotate upward along the connecting pipe 411, thereby expanding the internal volume of the clamping member 41, reducing the internal pressure, and causing the clamping member 41 to gradually contract and loosen the penis.

[0050] Example 4 like Figures 1-19 As shown, based on Embodiment 3, this embodiment provides a circumcision device that is easy to fix. This device clamps the foreskin circumferentially from both the inner and outer sides, preventing movement or misalignment of the foreskin during surgery due to external force interference, which could cause unevenness in the circumferential incision and affect the quality of suturing and surgery. The circumcision device also includes a foreskin fixing mechanism, which is sleeved outside the inner ring 1 and located inside the outer ring 2. It cooperates with the inner ring 1 to clamp or loosen the foreskin circumferentially.

[0051] The foreskin fixing mechanism includes: two movable semi-rings 51, installed inside the outer ring 2 and located outside the inner ring 1, with the upper end faces of the two movable semi-rings 51 flush with the upper end face of the outer ring 2; and a semi-ring drive assembly connected to the two movable semi-rings 51 for driving the two movable semi-rings 51 to move radially toward or away from each other along the inner ring 1.

[0052] As one specific implementation, the inner wall of the outer ring 2 is provided with an annular boss along the circumferential direction, and multiple square blocks are symmetrically arranged on the upper surface of the boss along the circumferential direction, and the multiple square blocks are arranged radially along the inner ring 1 and the outer ring 2.

[0053] The bottom ends of the two movable semi-rings 51 are symmetrically provided with multiple square grooves along the circumference. The two movable semi-rings 51 are installed on the boss of the inner ring 1, and the multiple square grooves and multiple square blocks can be matched one by one to limit the installation position and movement direction of the movable semi-rings 51.

[0054] The two movable semi-rings 51 can be assembled into a complete circular ring, which is located between the inner ring 1 and the outer ring 2, and the three are arranged coaxially. The upper end face of the circular ring is flush with the upper end faces of both the inner ring 1 and the outer ring 2. The circular ring and the inner ring 1 clamp the foreskin from both the inside and outside, forming a neat circumferential surface.

[0055] The semi-ring drive assembly is connected to the sidewalls of the two movable semi-rings 51, and can push the two movable semi-rings 51 to move radially towards or away from each other along the inner ring 1. When moving towards each other, they can be assembled into a complete ring, which cooperates with the inner ring 1 to clamp the foreskin; when moving away from each other, they separate into two movable semi-rings 51, releasing the outer surface of the foreskin.

[0056] The semi-ring drive assembly includes: a guide block 521, disposed at the center of the outer side wall of the movable semi-ring 51; a magnetic rod 522, one end of which is connected to the free end of the guide block 521; and a wedge block 523, disposed between the screw 421 and the piston rod 422, wherein the wedge block 523 contacts the other end of the magnetic rod 522, and the side wall of the wedge block 523 that contacts the magnetic rod 522 has an inclination angle, and the side wall is magnetically attracted to the magnetic rod 522.

[0057] In one specific implementation, one end of the guide block 521 is fixedly connected to the center point of the outer side wall of the movable semi-ring 51. A through hole is provided at the corresponding position of the outer ring 2, and the other end of the guide block 521 passes through the through hole. A circular cavity is provided at the center of the surface of the other end of the guide block 521 for connection with the magnetic rod 522.

[0058] The magnetic rod 522 has a T-shaped structure and is made of magnetic material. The free end of the vertical section of the magnetic rod 522 is fixedly connected to the circular cavity of the guide block 521. The end face of the horizontal section of the magnetic rod 522 is arc-shaped so as to slide and connect with the side wall of the wedge block 523.

[0059] The wedge block 523 has an inverted triangular structure, with its top wall center rotatably connected to one bottom end of the screw 421. The bottom end of the wedge block 523 is fixedly connected to the piston rod 422. One side wall of the wedge block 523 is slidably connected to the horizontal section of the magnetic rod 522. The upper end of the other side of the wedge block 523 is slidably connected to the crossbeam of the portal frame 322.

[0060] Specifically, the wedge block 523 has an open cavity at its top center, and one bottom end of the screw 421 is installed in the open cavity and can rotate within it. One side wall of the wedge block 523 has an inclination angle, and a magnetic sheet is provided on the surface of the side wall. The magnetic sheet is attracted to the magnetism of the magnetic rod 522.

[0061] The crossbeam of the portal frame 322 has an opening groove at its vertical center, and the upper end of the other waist of the wedge block 523 is placed in the opening groove to enhance the stability of the connection between the wedge block 523 and the other components. When the screw 421 rotates up and down along the portal frame 322, it drives the wedge block 523 to slide up and down along the opening groove.

[0062] When it is necessary to fix the foreskin, turn the knob clockwise or counterclockwise simultaneously to drive the screw 421 to rotate downward along the threaded through hole, and simultaneously squeeze the wedge block 523 to move downward. One waist of the wedge block 523 pushes the magnetic rod 522 to move towards the center of the inner ring 1, and then pushes the two moving half rings 51 to gradually merge into a complete ring, which cooperates with the inner ring 1 to clamp the foreskin.

[0063] When it is necessary to loosen the foreskin, rotate the knob in the opposite direction to drive the screw 421 to rotate upward along the threaded through hole, and simultaneously drive the wedge block 523 to move upward. One waist of the wedge block 523 gradually moves away from the magnetic rod 522, and through the magnetic attraction between the magnetic plate of the waist and the magnetic rod 522, it drives the two moving half rings 51 to gradually leave the inner ring 1 to loosen the foreskin.

[0064] The upper end of the outer ring 2 is provided with a plurality of first suture holes 21 along its circumference, the two movable half rings 51 are provided with second suture holes 511 corresponding to the first suture holes 21, and the inner ring 1 is provided with third suture holes 11 corresponding to the second suture holes 511.

[0065] In one specific implementation, when the two movable semi-rings 51 are assembled into a complete ring, the first sewing hole 21, the second sewing hole 511, and the third sewing hole 11 automatically align to form a complete through sewing hole. To facilitate threading and knotting, openings are provided between the first sewing hole 21 and the top wall of the outer ring 2, between the second sewing hole 511 and the top wall of the movable semi-ring 51, and between the third sewing hole 11 and the top wall of the inner ring 1.

[0066] The specific clinical application process of the technical solution of this invention is as follows: 1. In the initial state of the ring cutter, the screw 421 rotates upward to the limit position, that is, the wedge block 523 slides upward to the uppermost end of the opening slot of the gate frame 322. At this time, the clamping member 41 is in a natural extension and retraction state, and its inner contour is consistent with the inner contour of the outer ring 2. At the same time, the wedge block 523 moves away from the magnetic rod 522, and the two moving half-rings 51 are close to the inner wall of the outer ring 2, leaving sufficient space between them and the inner ring 1.

[0067] 2. Hold the crossbeam of the guide frame 31, place the inner ring 1 inside the patient's foreskin, and adjust the insertion depth and excision position.

[0068] 3. The ring assembly, consisting of the outer ring 2, positioning frame 32, circumcision fixing mechanism, and foreskin fixing mechanism, is fitted onto the top of the patient's penis and slides from top to bottom within the slide groove 311 via the slider 323. When the locking pin 324 engages with the locking hole 312, the alignment and locking of the upper surfaces of the outer ring 2, the movable half-ring 51, and the inner ring 1 are achieved.

[0069] 4. Rotating the screw 421 downwards causes the wedge block 523 and piston rod 422 to move downwards, reducing the internal volume of the clamping member 41 through the connecting pipe 411 and increasing the internal pressure, causing the clamping member 41 to gradually expand and clamp the penis. At the same time, the wedge block 523 pushes the magnetic rod 522 towards the center of the inner ring 1, thereby pushing the two moving half-rings 51 to gradually merge into a complete ring, which cooperates with the inner ring 1 to clamp the foreskin.

[0070] 5. Circumcision is performed using the circumferential cut surface formed by the two movable semi-rings 51 and the inner ring. After completion, suture holes are formed one-to-one through the first suture hole 21, the second suture hole 511 and the third suture hole 11 to suture the wound.

[0071] 6. Rotate the screw 421 upwards, causing the wedge block 523 to move upwards. Through the magnetic attraction of the wedge block 523 to the magnetic rod 522, the two moving half-rings 51 are pulled away from the inner ring 1 to release the foreskin. At the same time, the piston rod 422 is driven to move upwards along the connecting pipe 411, shrinking the internal volume of the clamping member 41, reducing the internal pressure, so that the clamping member 41 gradually contracts and releases the penis.

[0072] 7. Press and hold the crossbeam of the guide frame 31 and pull the ring assembly upward to separate the locking pin 324 from the locking hole 312. Continue to pull the ring assembly upward to disengage it from the guide frame 31. Then remove the inner ring 1 and the guide frame 31, and perform the relevant postoperative disinfection and finishing work.
