Description

Technical Field

[0001] The utility model relates to the technical field of flushers, in particular to a three-leaf flusher. Background Art

[0002] Irrigators are medical devices frequently used in minimally invasive surgery. They can irrigate the treated area and extract fluids from the area. Sometimes, for better irrigation, the front end of the irrigator is used to pry open the patient's wound tissue, allowing for more thorough irrigation and faster recovery. However, most irrigators on the market use irrigators with smooth front ends. This makes it difficult to pry open the wound during irrigation, requiring the use of other instruments to complete the irrigation, making it inconvenient to use. Therefore, we provide a three-leaf irrigator to address this problem. Utility Model Content

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4As shown, the utility model provides a technical solution: a three-leaf flusher, including a main body 1, a slide rod 5, a threaded joint 13 and a moving component.

[0024] An outer rod joint 2 is provided at one end of the main body 1, on which an outer rod 6 is detachably mounted, a clamp seat 10 is mounted on the outer rod 6, and three expansion heads 11 are hinged on the clamp seat 10. The expansion head 11 is a semi-cylindrical plate with a rounded front end. When closed, a space is left in the middle to facilitate wrapping the front end of the slide rod 5.

[0025] The slide rod 5 is slidably arranged in the outer rod 6. A connecting piece 12 is installed at one end of the slide rod 5, and the end of the connecting piece 12 away from the slide rod 5 is fixedly connected to the expansion head 11. The slide rod 5 can be moved in the outer rod 6 to drive the expansion head 11 to open and close by using the connecting piece 12. A splicing cap 3 is installed on the slide rod 5, and the slide rod 5 is installed on the outer rod joint 2 through the splicing cap 3.

[0026] The two ends of the outer rod joint 2 are respectively threadedly connected to the main body 1 and the outer rod 6. A sealing ring 4 is provided on the sliding rod 5, and the sealing ring 4 is located between the outer rod joint 2 and the assembled cap 3. The sealing ring 4 is used to improve the sealing between the outer rod joint 2 and the sliding rod 5.

[0027] The threaded joint 13 is fixedly connected to the main body 1, and a three-way valve 14 is installed on the threaded joint 13. The end of the slide rod 5 away from the connecting piece 12 is fixedly connected to the threaded joint 13, and the slide rod 5 is connected to the three-way valve 14 through the threaded joint 13, so that clean water can enter the slide rod 5 through the three-way valve 14 and the threaded joint 13, thereby completing the flushing of the wound through the slide rod 5.

[0028] The moving assembly is provided on the main body 1 and is used to control the sliding rod 5 to move laterally within the outer rod 6 to manipulate the opening and closing movements of the three expansion heads 11 .

[0029] The moving assembly includes a handle seat 16 fixedly connected to the main body 1, a rotating pin 9 fixedly connected to the handle seat 16, a slider 7 slidably connected in the main body 1, and the slider 7 is fixedly connected to the slide rod 5, an extrusion groove 8 is opened on the slider 7, and the rotating pin 9 is inserted into the extrusion groove 8.
