Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a circumcision stapler for circumcision and suture. Background Art

[0002] A circumcision stapler is a medical device often used in surgical operations on male penile prepuce tissue. In general surgical operations, the circumcision stapler is often used to complete the functions of tissue cutting and closing. The working principle of the circumcision stapler is to place the tissue between the staple cartridge group and the anvil group, and reasonably compress the tissue by adjusting the distance between the staple cartridge group and the anvil group. When the distance between the staple cartridge group and the anvil group reaches the safe range for effective suture, it is fired, and the U-shaped staples are compressed into D-shaped to suture the tissue and prevent bleeding.

[0003] In order to facilitate the use by personnel, some manufacturers in the market also sell electric circumcision staplers to replace manual circumcision staplers for operations on patients. In existing electric circumcision staplers, most of them use a motor as the power source, so that the device can perform circumcision on patients. However, when the motor is damaged during the use of the device, since the motor is often fixedly sealed in the device, it is inconvenient for personnel to disassemble the device to replace the motor, thus causing inconvenience to personnel in maintaining the electric circumcision stapler. Therefore, there are certain deficiencies.

[0004] In summary, it is very necessary to invent a circumcision stapler for circumcision and suture. Content of the Utility Model

Specific embodiments

[0021] The following will describe the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.

[0022] Referring to the attached Figures 1-5 , a circumcision stapler for circumcision suture provided by the present utility model includes a housing 100. The two housings 100 are arranged in a gun shape. A kiss-cutting mechanism 200 is installed at the muzzle end of the housing 100. A transmission shaft 350 is arranged at the rear end of the kiss-cutting mechanism 200 and inside the housing 100. A transmission rack 340 is installed at one end of the transmission shaft 350 away from the kiss-cutting mechanism 200. Through the transmission shaft 350 and the transmission rack 340, the kiss-cutting mechanism 200 can be pushed outwards, so that circumcision of the patient can be performed;

[0023] Inside the housing 100 and at the position of the pistol grip, a power component is provided. The power component includes a bottom support plate 322 which is slidably installed inside the housing 100. When a person needs to replace the drive motor 310, the bottom support plate 322 can be pulled out from the housing 100. A drive motor 310 is installed below the bottom end of the outer wall of the bottom support plate 322, and a battery supply 300 is installed at the bottom end of the outer wall of the drive motor 310. The battery supply 300 is provided to supply power to the drive motor 310. At the bottom end of the battery supply 300, an electronic control board for controlling the device is provided. The top end of the outer wall of the drive motor 310 can be fixed to the bottom end of the outer wall of the bottom support plate 322 by screws. At the top end of the outer wall of the bottom support plate 322 and above the drive motor 310, a driving gear 311 is rotatably connected. At the corresponding position of the top output end of the drive motor 310 and the driving gear 311, an output shaft 312 is fixed. The outer wall of the output shaft 312 is slidably connected to the inner wall of the driving gear 311. The output shaft 312 can be pulled out from the bottom end of the driving gear 311. Through holes are respectively opened at the top end of the outer wall of the bottom support plate 322 and at the corresponding position of the output shaft 312. The outer wall of the output shaft 312 is slidably connected to the inner wall of the through holes. The through holes are opened to facilitate the person to insert the output shaft 312 into the inner wall of the driving gear 311, so that the drive motor 310 can drive the driving gear 311 to rotate through the output shaft 312;

[0024] Above the top end of the outer wall of the bottom support plate 322 and on one side of the driving gear 311, a lower fixing cover 321 is lapped. Above the lower fixing cover 321, an upper fixing cover 320 is connected by a pin. The bottom end of the lower fixing cover 321 is fixed to the top end of the outer wall of the bottom support plate 322 by bolts. The lower fixing cover 321 and the upper fixing cover 320 can fix and protect the driving gear 311 and the driven gear set 330, and at the same time can ensure that the driving gear 311 and the driven gear set 330 can be stably meshed. Installation slots are respectively opened at the bottom end of the outer wall of the lower fixing cover 321 and at the corresponding position of the driving gear 311. The driving gear 311 is arranged in the installation slots. The installation slots are opened to avoid hindering the rotation of the driving gear 311 when the bottom end of the lower fixing cover 321 is fixed to the bottom support plate 322. A driven gear set 330 is meshed with the side end of the driving gear 311 on the inner wall of the lower fixing cover 321. The upper end of the driven gear set 330 is rotatably connected to the top end of the inner wall of the upper fixing cover 320. Slots are respectively opened at the corresponding position of the rear end of the outer wall of the upper fixing cover 320 and the transmission rack 340. The slots are opened to avoid hindering the left and right movement of the transmission rack 340 when the rear end of the upper fixing cover 320 is fixed to the rear end of the inner wall of the housing 100. The rear end of the outer wall of the upper fixing cover 320 is fixed to the inner wall of the rear housing 100. The front end of the outer wall of the transmission rack 340 is meshed with the rear end of the outer wall of the driven gear set 330.

[0025] The usage process of the present utility model is as follows: First, when in use, medical staff can press the trigger switch to enable the power supply battery 300 to supply power to the drive motor 310, so that the drive motor 310 can drive the driving gear 311 to rotate through the output shaft 312. When the driving gear 311 rotates, it can drive the driven gear set 330 to rotate through meshing. When the driven gear set 330 rotates, it can drive the transmission rack 340 to rotate, so that the transmission rack 340 can drive the kiss-cut mechanism 200 to move through the transmission shaft 350, enabling the kiss-cut mechanism 200 to perform circumcision on a person.

[0026] When the drive motor 310 fails, the user can remove the screws fixing the two outer shells 100 with a screwdriver. Then, the user can remove the screws fixing the upper fixing cover 320 and the outer shell 100 with a screwdriver. Then, the user can directly remove the bottom support plate 322, the upper fixing cover 320, and the drive motor 310. Then, the user can pull the upper fixing cover 320 upward to separate it from the lower fixing cover 321. Then, use a screwdriver to remove the screws between the lower fixing cover 321 and the bottom support plate 322. Then, the user can pull the lower fixing cover 321 upward. Then, the user can unscrew the screws fixing the drive motor 310 and the bottom support plate 322 to remove the drive motor 310 for replacement.

[0027] The above is only the preferred embodiment of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present utility model falls within the scope of protection required by the present utility model.
