DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figs. 1-3 An endoscope forceps cleaning brush includes a mounting base 1, a pull ring 2 fixedly installed at the rear end of the mounting base 1, a tube 3 fixedly connected to the front end of the mounting base 1, a cleaning component 4 installed inside the pull ring 2, and a protective component 5 installed outside the tube 3.

[0023] See Fig. 2 Furthermore, the cleaning component 4 includes a rod 6, which is movably installed inside the tube 3. A set of brushes 7 is provided on the front end of the outside of the rod 6. A cleaning groove 8 is provided on the front end of the inside of the tube 3. A screw groove 9 is provided at the rear end of the fixing seat 1. A stud 10 is fixedly installed at the rear end of the rod 6. A knob 11 is fixedly installed at the rear of the stud 10.

[0024] The rod 6 is located inside the tube 3 and is slidably arranged. The diameter of the cleaning groove 8 is larger than the diameter of the rod 6. By pulling the rod 6, the brush 7 is retracted into the cleaning groove 8, thereby squeezing and scraping away the dirt on the surface of the brush 7.

[0025] The brush 7 is wrapped around the outside of the rod 6. The stud 10 and the screw groove 9 are connected by threads. The rod 6 is fixed by the connection between the stud 10 and the screw groove 9, thereby allowing the brush 7 to extend and be fixed.

[0026] Specifically, the brush 7 washes away the dirt in the endoscope forceps channel. The dirt adheres to the surface of the brush 7. By rotating the knob 11, the stud 10 is disengaged from the screw groove 9, and the knob 11 is pulled to slide the rod 6, causing the brush 7 to retract into the cleaning groove 8. The dirt adhering to the brush 7 is squeezed and scraped off through the groove opening of the cleaning groove 8. The brush 7 is cleaned at the same time as the endoscope forceps channel is cleaned by the injected cleaning fluid.

[0027] Example 2

[0028] See Fig. 3 Furthermore, based on Embodiment 1, a screw ring 12 is fixedly installed at the front of the fixing seat 1, a rubber ring 13 is installed on the front end of the outside of the tube 3, and the protective component 5 includes a protective cover 14. The protective cover 14 is movably installed on the outside of the tube 3, a slot 15 is opened at the rear end of the inside of the protective cover 14, and an annular groove 16 is opened at the rear of the protective cover 14.

[0029] The protective cover 14 is slidably fitted onto the outside of the tube 3. The inner diameter of the protective cover 14 is larger than the outer diameter of the brush 7. The protective cover 14 is located outside the brush 7 and is fixed by the rubber ring 13 to improve the protection of the brush 7.

[0030] The rubber ring 13 is snapped into the groove 15, and the screw ring 12 is threaded into the groove 16. The screw ring 12 is connected to the groove 16 by sliding the protective cover 14, so as to fix the protective cover 14.

[0031] Specifically, during the cleaning process, the protective cover 14 slides outside the tube strip 3, so that the screw ring 12 is connected and fixed with the ring groove 16. When the cleaning is completed and the tube is left to stand, the protective cover 14 is slid to the outside of the brush 7 and fixed by the engagement of the rubber ring 13 with the slot 15, thereby improving the protection of the brush 7.

[0032] In actual operation, the brush 7 is used to clean the endoscope forceps channel, the rod 6 is used to drive the brush 7 to slide, and the protective cover 14 is used to protect the brush 7.

[0033] During cleaning, some dirt adheres to the surface of the brush 7. By rotating the knob 11, the stud 10 is disengaged from the screw groove 9. By pulling the knob 11, the rod 6 slides inside the tube 3. The tube 3 drives the brush 7 to retract into the cleaning groove 8. The brush 7 is squeezed through the groove opening of the cleaning groove 8, and the dirt adhering to the surface of the brush 7 is scraped off. This achieves cleaning of the endoscope forceps channel while cleaning the brush 7, reducing repeated contact with dirt.

[0034] During the cleaning process, the protective cover 14 is slid to the rear end outside the tube 3. The protective cover 14 is fixed to the fixed base 1 by the connection between the screw ring 12 and the ring groove 16. The protective cover 14 reduces the splashing of cleaning fluid inside the clamp channel. When the cleaning is completed and the brush is left to stand, the protective cover 14 is slid to the outside of the brush 7, so that the rubber ring 13 is locked in the slot 15 for fixation, thereby improving the protection of the brush 7.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
