Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a testicle traction device used after cryptorchidism surgery. Background Art

[0002] During normal development, the testicles will descend from the retroperitoneum of the waist to the scrotum. If they do not descend or descend incompletely, the testicles are not located in the normal scrotum, but in the inguinal canal, or even the pelvic cavity, or in the higher retroperitoneal area. There are no testicles in the scrotum or only one side of the testicle. This condition is called cryptorchidism, clinically also known as incomplete testicular descent or undescended testicles. Currently, in the postoperative treatment of cryptorchidism in children, a traction device is required to pull and lift the scrotum to facilitate the doctor's subsequent treatment.

[0003] Existing testicular traction devices for cryptorchidism surgery, such as Chinese patent publication number CN217339053U, disclose a testicular traction device for cryptorchidism surgery in children. The device drives a first threaded rod to rotate by controlling the operation of a motor. The rotation of the first threaded rod drives the handle to adjust its height through the cooperation of a threaded sleeve and a push rod, making it convenient for people of different heights and operating habits to push the device. This solves the problem of inconvenient adjustment of existing testicular traction devices for cryptorchidism surgery in children and has the advantage of easy adjustment.

[0004] However, the adjustment of the grip is driven by a motor, and the adjustment range is small. At the same time, the device needs to be connected to a power source when in use, which is not convenient and not easy to adjust quickly. The scrotum is placed in the lifting shell to adjust the height, and the adjustment of the lifting shell is not flexible enough. Utility Model Content

A worm 27 meshing with the worm wheel 26 is rotatably installed inside the guide housing 21, and a rotating handle 28 is fixedly installed on the bottom of the worm 27.

[0027] By rotating the handle 28, the worm 27 is driven to rotate, which in turn drives the worm wheel 26 to rotate, and then drives the rotating shaft 24 to rotate while driving the gear 25 to rotate. The rotation of the gear 25 cooperates with the internal tooth groove 23 to drive the sliding column 22 to slide upward along the inside of the guide shell 21. The sliding column 22 drives the connecting block 29 and the handle 5 to be raised and lowered to adjust the height, making it convenient for people of different heights and operating habits to push the device, and no external power supply is required, making operation adjustment and use convenient.

[0028] like Figure 4 and Figure 5 As shown, the adjustment assembly 3 includes a guide frame 31, a threaded column 32 is rotatably installed on the inner side of the guide frame 31, a hand wheel 33 connected to the threaded column 32 is provided on the top of the guide frame 31, the external thread of the threaded column 32 is connected to a slider 34, the front side of the slider 34 is movably hinged with a telescopic sleeve 35, and the other end of the telescopic sleeve 35 is movably hinged with a connecting block 2 37.

[0029] By rotating the hand wheel 1 33, the threaded column 32 is driven to rotate and drive the slider 34 to slide up and down. By operating the hand screw bolt 1 36 and the hand screw bolt 2 38, the angle can be adjusted by rotating along the inner side of the slider 34 and the telescopic sleeve 35 respectively. The telescopic sleeve 35 can be extended. The scrotum is placed in the lifting shell 4 for traction and lifting. It is easy to adjust and easy to operate, which improves the flexibility of adjustment.

[0030] like Figure 3 As shown, the gear 25 is located above the rear side of the sliding column 22 , and the gear 25 is meshed with the internal tooth groove 23 .

[0031] The gear 25 is located above the rear side of the sliding column 22 and meshes with the inner tooth groove 23. When the gear 25 rotates, the sliding column 22 with the inner tooth groove 23 is driven to rise and adjust the height, which is convenient for people of different heights and operating habits to use.

[0032] like Figure 3 As shown, the worm wheel 26 is located on the left side of the gear 25 , and the worm 27 is installed on the rear side of the worm wheel 26 .

[0033] The worm 27 at the rear can drive the worm wheel 26 to rotate, and the worm wheel 26 can drive the sliding column 22 to rise and fall. The worm wheel 26 and the worm 27 can be self-locked to improve the convenience of adjustment.

[0034] like Figure 3 As shown, the top of the sliding column 22 is fixedly connected to a connecting block 29 , and the handle 5 is fixedly installed on the left and right sides of the connecting block 29 .

[0035] The connection block 29 is provided to facilitate connection and installation with the handle 5 , and the sliding column 22 is limited by the connection block 29 .

[0036] like Figure 5 As shown, the outer thread of the slider 34 is installed with a hand-tightening bolt 36 that penetrates the telescopic sleeve 35, and the outer thread of the telescopic sleeve 35 is installed with a hand-tightening bolt 38 that penetrates the connecting block 2 37.

[0037] The hand screw bolt 1 36 and the hand screw bolt 2 38 can be used to loosen or tighten the screw bolts, thereby adjusting the angles of the telescopic sleeve 35 and the connecting block 2 37 . The adjustment is flexible and easy to use.

[0038] like Figure 5 As shown, the lifting shell 4 is movably engaged with the interior of the second connecting block 37 .

[0039] By clamping the lifting shell 4 inside the second connecting block 37, the direction can be adjusted by rotation, thereby improving flexibility.

[0040] like Figure 2 As shown, a universal wheel 6 is fixedly mounted on the bottom of the base 1 .

[0041] The universal wheels 6 can be self-locked, making it easy to move and fix the device for use.

[0042] The following is a detailed description of the working principle of the testicular traction device used after cryptorchidism surgery.

[0043] like Figures 1 to 5 As shown, by rotating the rotating handle 28 located on the upper rear side of the guide housing 21, the worm 27 is driven to rotate by rotating the handle 28, wherein the worm 27 and the worm wheel 26 cooperate, and the worm wheel 26 can be driven to rotate by the worm 27. The worm wheel 26 and the gear 25 are both installed outside the rotating shaft 24. The worm wheel 26 drives the rotating shaft 24 to rotate while driving the gear 25 to rotate. The gear 25 is engaged with the internal tooth groove 23 provided on the rear side of the sliding column 22. The rotation of the gear 25 drives the sliding column 22 to slide upward along the inside of the guide housing 21, and drives the connecting block 29 and the side of the connecting block 29 through the sliding column 22. The handle 5 on the surface can be raised and lowered to adjust the height, which is convenient for people of different heights and operating habits to push the device. By turning the hand wheel 1 33, the threaded column 32 located in the guide frame 31 can be driven to rotate, and the rotation of the threaded column 32 drives the slider 34 located in the guide frame 31 to slide up and down. At the same time, by loosening the hand screw 1 36 and the hand screw 2 38, the angle can be adjusted along the inner side of the slider 34 and the telescopic sleeve 35 respectively, and then the hand screw 1 36 and the hand screw 2 38 are tightened to fix it. The telescopic sleeve 35 can be extended, and the scrotum can be placed in the lifting shell 4 and pulled and lifted by the lifting shell 4.

[0044] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
