Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable foreskin anastomosis device. Background Art

[0002] Phimosis is a common male reproductive problem. It refers to the condition in which the glans penis is partially or completely covered by the foreskin. If not treated properly, this condition can lead to balanitis and post-operative inflammation. Currently, circumcision is typically performed using laser or mechanical direct removal. This method results in an uneven and incomplete incision, heavy bleeding, prolonged surgery, and poor recovery. Consequently, circumcision with a circumcision device and a stapler have emerged. These devices can remove excess foreskin in one go, minimizing bleeding and creating a neat anastomosis. During foreskin removal, the staples in the circumcision device's cartridge are pushed out by a pusher assembly and inserted into the partially removed glans penis. This eliminates the need for manual sutures and significantly shortens surgical time. The cross-section of the staples prevents skin from tangling with the wound, and the titanium staples fall out naturally afterward, eliminating the need for suture removal, significantly reducing recovery time. For example, Chinese patent CN213758459U discloses a circumcision suturing device, which includes a glans base, a knife anvil ring, a nail anvil ring, a shell, an annular nail magazine, an abutment, a pull rod, a propulsion mechanism and an adjustment knob. The glans base is provided with multiple small holes near the nail anvil ring, and a channel is provided on the side wall of the glans base. The channel is connected to the small holes and an external hose, and the external hose is connected to a water-based lubricant storage container. A suture staple outlet is provided above the annular nail magazine, and a plurality of arc-shaped gaskets are also provided on the annular nail magazine. The arc-shaped gaskets cover the suture staple outlet, and the arc-shaped gaskets and the annular nail magazine are on the same front projection plane. When using the above patent, the glans seat needs to be removed first and placed into the foreskin of the penis. The doctor fixes the foreskin on the glans cover, and then installs the glans seat back into the circumcision suture instrument. Finally, the handle is pressed to fire the tool and suture nail to achieve the removal and suturing of the foreskin. In the process of installing the glans seat back into the suture instrument, the part of the foreskin that is sleeved on the outside of the glans seat will touch the tool, which not only affects the smoothness of the installation, but also causes contamination of the tool and affects the stability of use.

[0003] Therefore, it is necessary for those skilled in the art to provide a disposable circumcision stapler, add a protective device to the tool portion, and improve the smoothness of installation and the safety of use. Utility Model Content

[0025] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0026] See also Figures 1 to 4 The utility model provides a disposable foreskin stapler, including a firing device 10 and a mounting device 20. The mounting device 20 is used to be placed in the foreskin of the penis. The foreskin to be cut is placed on the outside of the mounting device 20, and then the mounting device 20 is slidably mounted on the firing device 10. The firing device 10 includes a knife 11 and a suture nail 12. When in use, the foreskin on the mounting device 20 is cut and sutured by sequentially firing the knife 11 and the suture nail 12.

[0027] Furthermore, the mounting device 20 includes a glans base 21 and a mounting rod 22. The glans base 21 is a cylindrical structure and is placed inside the foreskin of the penis. The foreskin to be cut is placed outside the glans base 21. One end of the mounting rod 22 is fixedly connected to the glans base 21, and the other end of the mounting rod 22 is threaded into the firing device 10. The mounting device 20 is slidably disposed within the firing device 10. A nail seat 23 is also provided on the glans base 21 of the mounting device 20, and the nail seat 23 faces the firing device 10.

[0028] Furthermore, the firing device 10 includes a shell 13, a handle 14 located on the shell 13, and a firing tube 15 slidably arranged in the shell 13. The shell 13 is a cylindrical structure with a hollow interior. The handle 14 pushes the firing tube 15 to slide in the shell 13. The tool 11 and the suture nail 12 are installed on one end of the firing tube 15 facing the glans seat 21. The tool 11 and the suture nail 12 are facing the nail seat 23. The nail seat 23 and the shell 13 can abut each other. At the same time, the firing tube 15 pushes the tool 11 and the suture nail 12 to move and can abut against the nail seat 23.

[0029] During use, the operator separates the installation device 20 from the firing device 10, places the glans seat 21 in the installation device 20 into the foreskin of the penis and fixes the foreskin on the outside of the glans seat 21, and then reinstalls the installation device 20 into the firing device 10, so that the installation device 20 is in the pre-cutting position in the firing device 10, presses the handle 14, and causes the firing tube 15 to push and fire the knife 11 and the suture nail 12 to complete the cutting and suturing of the foreskin.

[0030] It can be understood that the firing device 10 used in the present invention is a common circumcision stapler on the market, which also includes components such as an adjustment knob and a safety lock. The specific structure can be found in a circumcision stapler disclosed in Chinese patent CN213758459U, and no further details will be given here.

[0031] See also Figures 5 to 9 An isolation membrane 30 is also provided between the firing device 10 and the mounting device 20. The isolation membrane 30 is partially sleeved on the tool 11. One end of the isolation membrane 30 is glued to the inner wall of the firing tube 15, and the other end of the isolation membrane 30 is glued to the outside of the shell 13.

[0032] Furthermore, a guide tube 16 is provided on the end of the shell 13 near the nail seat 23, one side of the guide tube 16 faces the nail seat 23, and the other side of the guide tube 16 faces the firing tube 15. The suture nail 12 is located between the guide tube 16 and the firing tube 15. The suture nail 12 is slidably arranged in the guide tube 16 and passes through the guide tube 16. The suture nail 12 is evenly and orderly abutted against the nail seat 23 through the guide tube 16, thereby achieving uniform suturing of the skin.

[0033] A protective sleeve 17 is further provided on the end surface of the guide cylinder 16 facing the nail seat 23, and the protective sleeve 17 is used to prevent the suture nail 12 from falling out of the guide cylinder 16 when not in use, thereby ensuring the stability of the utility model.

[0034] The cutter 11 is cylindrical, one end of the cutter 11 is connected to the inner wall of the firing tube 15 , and the other end of the cutter 11 extends outside the firing tube 15 and is located below the guide tube 16 . The cutter 11 can abut the nail seat 23 .

[0035] In this embodiment, the staple holder 23 comprises an outer ring and an inner ring. The outer ring has a teardrop-shaped groove on its surface facing the staple 12. The staple 12 fits into the groove and deforms when pressed against the outer ring, similar to the bending of a staple in a stapler, thereby achieving suturing. The inner ring has a flat surface facing the cutter 11, which the cutter 11 can abut against to ensure a complete cut.

[0036] The isolation membrane 30 is partially located between the nail seat 23 and the shell 13. One end of the isolation membrane 30 is adhered to the inner wall of the firing cylinder 15 using non-stick adhesive, and the other end of the isolation membrane 30 extends to the outside of the shell 13 and is adhered to the outside of the shell 13 using non-stick adhesive. The tool 11 is located within the isolation membrane 30, and the isolation membrane 30 is attached to the end of the tool 11 facing the nail seat 23. The present invention protects the tool 11 by wrapping the isolation membrane 30 around the cutting end of the tool 11. When the mounting device 20 is wrapped with foreskin and mounted on the firing device 10, excess foreskin will extend between the firing cylinder 15 and the glans seat 21, and thus easily touch the tool, which not only affects the smoothness of installation, but also causes tool contamination and affects the stability of use. Therefore, the utility model wraps the isolation membrane 30 around the cutting end of the tool 11 and places the isolation membrane 30 between the glans seat 21 and the tool 11. The isolation membrane 30 abuts against the foreskin to be cut, so that the foreskin cannot directly touch the tool 11, thereby preventing the tool 11 from being contaminated, while ensuring the smoothness of installation and cutting.

[0037] In this embodiment, lubricating oil may be applied to the isolation membrane 30 to further ensure the stability of the installation of the installation device 20 and the smoothness of the removal of the isolation membrane 30.

[0038] Furthermore, the isolation membrane 30 is provided with a tear seam 30, and a plurality of tear seams 30 are provided and are evenly arranged on the outer surface of the isolation membrane 30 around the axis of the isolation membrane 30. A tear seam 30 is composed of a plurality of spaced through grooves arranged and combined, and the through grooves penetrate the wall of the isolation membrane 30, so that the tear seam 30 can be quickly torn open while protecting the knife 11. During use, when the installation device 20 is wrapped with the foreskin and installed on the firing device 10, the excess foreskin will extend between the firing cylinder 15 and the glans seat 21. At this time, the operator pulls the isolation membrane 30 outward and tears the isolation membrane 30 from the tear seam 30, so that the isolation membrane 30 is removed, and at the same time, the protective cover 17 is removed, and the installation device 20 is further fixed to the firing device 10 so that the nail seat 23 abuts against the guide cylinder 16. At this time, the foreskin is located between the nail seat 23 and the guide cylinder 16, and the installation is completed.

[0039] The utility model utilizes a tearable isolation membrane 30 to prevent the cutter 11 from directly contacting the foreskin before the foreskin reaches a predetermined position, thereby improving safety and installation stability. After positioning is completed, the isolation membrane 30 is directly torn off to quickly remove the protective device, ensuring the smoothness and efficiency of the operation and improving the stability of use.

[0040] The specific operation method in this embodiment is as follows: step 1: separate the installation device 20 from the firing device 10, the glans seat 21 is used to be placed in the foreskin of the penis, the foreskin to be cut is placed on the outside of the glans seat 21, and then the installation device 20 is reinstalled on the firing device 10 to complete the preliminary installation.

[0041] Step 2: After the installation device 20 is wrapped by the foreskin and installed on the firing device 10, the excess foreskin will extend between the firing tube 15 and the glans seat 21. At this time, the operator pulls the isolation membrane 30 outward and tears the isolation membrane 30 from the tear seam 30, so that the isolation membrane 30 falls out, and at the same time removes the protective cover 17 to complete the removal of the protective device.

[0042] Step 3: Further fix the mounting device 20 to the firing device 10 so that the nail seat 23 abuts against the guide tube 16 to complete the installation.

[0043] Step 4: Press the handle 14 to make the firing tube 15 push and fire the cutter 11 and the suture staple 12. The cutter 11 cuts the foreskin and the suture staple 12 sutures the foreskin, completing the cutting and suturing of the foreskin.

[0044] The present invention protects the cutting end of the cutter 11 by wrapping an isolation membrane 30 around it. When the mounting device 20 is wrapped with the foreskin and mounted on the firing device 10, the excess foreskin will extend between the firing cylinder 15 and the glans base 21, thereby easily contacting the cutter. This not only affects the smoothness of installation, but also causes contamination of the cutter, affecting its stability in use. Therefore, the present invention wraps the isolation membrane 30 around the cutting end of the cutter 11 and positions the isolation membrane 30 between the glans base 21 and the cutter 11, thereby preventing the foreskin from directly contacting the cutter 11, thereby preventing contamination of the cutter 11 and ensuring smooth installation and cutting.

[0045] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
