Abstract
Description
Technical Field
[0001] This application relates to the field of circumcision, and more particularly to a circumcision aid. Background Technology
[0002] A circumcision device is an instrument used in male circumcision surgery, a common surgical procedure used to treat foreskin-related conditions such as phimosis and paraphimosis. The surgery addresses foreskin-related health issues by removing the foreskin from areas that are too long, too narrow, or have other problems. A circumcision device is a specialized instrument for circumcision, typically made of stainless steel or medical-grade plastic. In a standard circumcision device, the medical staff holds and operates it through a fixed tube. A connecting cover is slidably installed on the inner wall of the fixed tube, contacting the patient's genitals to prevent injury or infection. The foreskin is then connected to the inner wall of the fixed tube. A pressing handle is rotatably mounted on the surface of the fixed tube. Pressing the pressing handle causes the blade inside the fixed tube to cut the foreskin, and the foreskin is then sutured using a staple cartridge within the fixed tube.
[0003] Regarding the aforementioned technologies, the inventors believe that conventional circumcision devices often require adjustment of the required foreskin length based on the foreskin length of different patients. The conventional method of adjustment by medical personnel makes it difficult to control the cutting precision and is also quite difficult to operate, resulting in an increase in the time required for circumcision.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0005] To address the problem of difficulty in adjusting the foreskin length when using conventional circumcision devices, this application provides a circumcision aid.
[0006] The circumcision aid provided in this application adopts the following technical solution:
[0007] A circumcision aid includes a fixed cylinder and two take-up rollers. Two pressing handles are rotatably mounted on the surface of the fixed cylinder, and the two pressing handles are symmetrically distributed about the fixed cylinder axis. A connecting cover is slidably connected to the inner wall of the fixed cylinder. A fixed frame is rotatably mounted on the surface of the two take-up rollers, and a connecting block is fixedly connected to one end of the take-up rollers. A synchronous belt is drivenly mounted on the surface of the connecting block. A reversing gear is drivenly connected to the inner wall of the synchronous belt. A rotating block is fixedly mounted to one end of the reversing gear. The center of the connecting cover is on the same straight line as the center of the fixed cylinder. The inner wall of the fixed frame is slidably connected to the surface of the connecting cover. The cross-section of the fixed frame is V-shaped.
[0008] Preferably, one end of the connecting block and the reverse gear are rotatably mounted to the inner wall of the fixed frame, the two reverse gears mesh with each other, and the center of the rotating block and the center of the reverse gear are on the same straight line.
[0009] Preferably, the two take-up rollers are symmetrically distributed about the fixed frame, and the take-up rollers are rubber tubes.
[0010] Preferably, a push spring is fixedly installed at the bottom end of the fixing frame, the bottom end of the push spring is fixedly connected to the surface of the connecting cover, and the center of the push spring and the center of the fixing frame are on the same straight line.
[0011] Preferably, a test gauge is fixedly mounted on the surface of the fixing frame, and a plurality of scale marks are fixedly connected to the inner wall of the test gauge. The plurality of scale marks are arranged in a circular array with the center of the test gauge as the axis. A pointer is rotatably mounted on the inner wall of the test gauge, and one end of the pointer is fixedly connected to the surface of the connecting block.
[0012] Preferably, two limiting frames are rotatably mounted on the surface of the fixed frame. The two limiting frames are symmetrically distributed about the fixed frame, and each of the two limiting frames has a mounting clip fixedly connected to one end that is close to the other.
[0013] Preferably, a limiting spring is fixedly installed on the surface of the fixing frame, and one end of the limiting spring is engaged with the surface of the limiting frame.
[0014] In summary, this application includes the following beneficial technical effects:
[0015] 1. By installing the fixing frame at the bottom of the connecting cover, two winding rollers are rotatably connected to the inner wall of the fixing frame. A connecting block is installed at one end of each winding roller, and a reverse gear is installed at one end of the connecting block via a synchronous belt. A rotating block is installed at one end of the reverse gear, so that the rotation of the reverse gear can be controlled by the rotating block, thereby driving the rotation of the connecting block at one end of the synchronous belt. This allows the winding roller at the connecting block end to control the length of the patient's foreskin, facilitating adjustment of the foreskin length by medical staff. One end of each of the two reverse gears is rotatably connected to the surface of the fixing frame, and the two reverse gears mesh with each other. This allows the rotation of the rotating block to control the two reverse gears, causing the two winding rollers to rotate in opposite directions, thereby controlling the length of the two points of contact with the foreskin synchronously. This makes it more convenient to use. Both winding rollers are rubber rollers, so that the rubber material can increase the friction with the foreskin, and the rubber material is relatively soft to avoid causing discomfort to the patient. Compared with existing technologies, this effectively improves the ease of use of the foreskin cutter.
[0016] 2. A push spring can also be installed at the bottom of the fixed frame. The bottom of the push spring is fixedly connected to the surface of the connecting cover, so that the fixed frame can be pushed by the push spring to connect the take-up roller inside the fixed frame to the surface of the cover. This effectively improves the take-up roller's winding effect on the cover and avoids slippage between the take-up roller and the cover. A gauge is installed on the surface of the fixed frame. Several scales are installed on the inner wall of the gauge, and a pointer is rotatably connected to the inner wall of the gauge. One end of the pointer is fixedly installed to one end of the connecting block, so that the pointer can follow the rotation of the take-up roller at one end of the connecting block, thereby calibrating the scales to measure the take-up roller. The rotation angle is detected to measure the length of the foreskin wound by the take-up roller. A limit frame is rotatably mounted on the surface of the fixed frame, and an installation clip is installed at one end of the limit frame to fix the foreskin surface. This facilitates the fixation of one end of the foreskin and reduces the difficulty of operation for medical personnel. A limit spring is installed on the inner wall of the fixed frame, and one end of the limit spring engages with the surface of the limit frame to push the limit frame and keep the installation clip at one end of the limit frame fixed to the foreskin surface, effectively improving the fixing effect of the installation clip and thus improving the use effect of the device.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.
[0023] This application discloses a circumcision aid, as shown in the embodiments below. Figure 1 - Figure 2The device includes a fixed cylinder 1, which is held and operated by medical staff during use. A connecting cover 3 is slidably installed on the inner wall of the fixed cylinder 1. The connecting cover 3 is brought into contact with the patient's genitals to prevent injury or infection. The foreskin is connected to the inner wall of the fixed cylinder 1. A pressing handle 2 is rotatably installed on the surface of the fixed cylinder 1. By pressing the pressing handle 2, the blade inside the fixed cylinder 1 cuts the foreskin, and the foreskin is sutured with the staple cartridge inside the fixed cylinder 1. A fixing frame 5 is installed at the bottom of the connecting cover 3. Two winding rollers 4 are rotatably connected to the inner wall of the fixing frame 5. A connecting block 6 is installed at one end of the winding roller 4. A reversing gear 9 is installed at one end of the connecting block 6 via a synchronous belt 7. A rotating block 8 is installed at one end of the reversing gear 9. The rotating block 8 controls the rotation of the reversing gear 9, thereby driving the connecting block 6 at one end of the synchronous belt 7 to rotate. This allows the winding roller 4 at one end of the connecting block 6 to control the length of the patient's foreskin, making it convenient for medical staff to adjust the foreskin length and effectively improving the ease of use of the foreskin cutter.
[0024] Reference Figure 2 One end of each of the two reverse gears 9 is rotatably connected to the surface of the fixed frame 5. The two reverse gears 9 mesh with each other. After the rotating block 8 rotates, it controls the two reverse gears 9 to rotate the two winding rollers 4 in opposite directions, thereby controlling the winding rollers 4 to synchronously control the length of the two points in contact with the foreskin. This makes it more convenient to use. Both winding rollers 4 are rubber rollers. The rubber material of the winding rollers 4 increases the friction with the foreskin, and the rubber material is relatively soft to avoid causing discomfort to the patient.
[0025] Reference Figure 2 - Figure 4A push spring 10 is installed at the bottom of the fixed frame 5. The bottom of the push spring 10 is fixedly connected to the surface of the connecting cover 3. The push spring 10 pushes the fixed frame 5, connecting the take-up roller 4 inside the fixed frame 5 to the surface of the cover, effectively improving the take-up effect of the take-up roller 4 on the cover and avoiding slippage between the take-up roller 4 and the cover. A gauge 11 is installed on the surface of the fixed frame 5. Several scale marks 13 are installed on the inner wall of the gauge 11, and a pointer 12 is rotatably connected to the inner wall of the gauge 11. One end of the pointer 12 is fixedly installed to one end of the connecting block 6. The pointer 12 follows the rotation of the take-up roller 4 at one end of the connecting block 6, thereby cooperating with the scale marks 13. 3. The rotation angle of the take-up roller 4 is detected to detect the length of the foreskin taken up by the take-up roller 4. A limit frame 14 is rotatably installed on the surface of the fixing frame 5. An installation clip 15 is installed at one end of the limit frame 14. The installation clip 15 at one end of the limit frame 14 is fixed to the surface of the foreskin, which facilitates the fixation of one end of the foreskin and reduces the operation difficulty for medical staff. A limit spring 16 is installed on the inner wall of the fixing frame 5. One end of the limit spring 16 is engaged with the surface of the limit frame 14. The limit spring 16 pushes the limit frame 14 to keep the installation clip 15 at one end of the limit frame 14 fixed to the surface of the foreskin, which effectively improves the fixing effect of the installation clip 15.
[0026] The implementation principle of the circumcision aid in this application embodiment is as follows: A fixing frame 5 is installed at the bottom of a connecting cover 3. Two winding rollers 4 are rotatably connected to the inner wall of the fixing frame 5. A connecting block 6 is installed at one end of each winding roller 4. A reverse gear 9 is installed at one end of each connecting block 6 via a synchronous belt 7. A rotating block 8 is installed at one end of each reverse gear 9, allowing the rotating block 8 to control the rotation of the reverse gear 9, thereby driving the connecting block 6 at one end of the synchronous belt 7 to rotate. This allows the winding roller 4 at one end of the connecting block 6 to control the length of the patient's foreskin, facilitating adjustment of the foreskin length by medical personnel. One end of each of the two reverse gears 9 is rotatably connected to the surface of the fixing frame 5, and the two reverse gears 9 mesh with each other. This allows the rotating block 8 to control the two reverse gears 9 to rotate the two winding rollers 4 in opposite directions, thus controlling the length of the two points in contact with the foreskin synchronously. This makes it more convenient to use. Both winding rollers 4 are rubber rollers, which increases friction with the foreskin, and the rubber material is relatively soft, avoiding discomfort to the patient.
[0027] A push spring 10 can also be installed at the bottom of the fixing frame 5. The bottom of the push spring 10 is fixedly connected to the surface of the connecting cover 3, so that the fixing frame 5 can be pushed by the push spring 10 to connect the take-up roller 4 inside the fixing frame 5 to the surface of the cover, effectively improving the take-up roller 4's take-up effect on the cover and avoiding slippage between the take-up roller 4 and the cover. A gauge 11 is installed on the surface of the fixing frame 5. Several scale marks 13 are installed on the inner wall of the gauge 11, and a pointer 12 is rotatably connected to the inner wall of the gauge 11. One end of the pointer 12 is fixedly installed to one end of the connecting block 6, so that the pointer 12 can follow the rotation of the take-up roller 4 at one end of the connecting block 6, thereby cooperating with the scale marks. The rotation angle of the take-up roller 4 is detected to detect the length of the foreskin wound by the take-up roller 4. A limit frame 14 is rotatably installed on the surface of the fixing frame 5. An installation clip 15 is installed at one end of the limit frame 14 to fix the foreskin surface with the installation clip 15 at one end of the limit frame 14, which facilitates the fixation of one end of the foreskin and reduces the operation difficulty for medical staff. A limit spring 16 is installed on the inner wall of the fixing frame 5. One end of the limit spring 16 is engaged with the surface of the limit frame 14 to push the limit frame 14 with the limit spring 16 to keep the installation clip 15 at one end of the limit frame 14 fixed to the foreskin surface, effectively improving the fixing effect of the installation clip 15.
[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
