TECHNICAL FIELD

[0001] The utility model relates to the field of ophthalmic operation auxiliary instrument, especially a foot pedal flusher for ophthalmic operation. BACKGROUND

[0002] In ophthalmic operation, instruments are needed to maintain the open eyes of patients, thus causing the cornea of the patients to dry, and there are potential operation risks such as unclear vision when the main operator observes the cornea of the patients. Therefore, in the existing ophthalmic operation, the main operator usually needs the help of an assistant to repeatedly flush the cornea and conjunctival tissue of the patients to maintain their transparency and wet state.

[0003] However, in ophthalmic microsurgery, the assistant often needs to perform other key operations on the sterile operating table, for example: in cataract surgery, the assistant needs to assemble an artificial lens on the sterile table; if the cornea of the patient on the operating table dries during this process, the main operator will be forced to pause the operation and wait for the assistant to complete the current task before wetting the cornea of the patient. In addition, the blurred vision caused by the dry cornea may also cause some unpredictable operation risks. SUMMARY

[0027] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0028] The present application uses a syringe fixing support to fix the syringe filled with liquid on the surgical microscope, the main doctor inflates the squeeze air bag by stepping on the inflatable pedal, squeezes the syringe, and the liquid in the syringe flows out to moisten the eye surgery area. After the surgery is completed, the squeeze air bag is deflated by stepping on the deflation pedal, and the syringe can be directly removed. The process is simple, and the safety and efficiency of ophthalmic surgery can be improved.

[0029] In order to better understand the above technical solutions, the exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0030] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings and specific embodiments.

[0031] Figures 1 to 5 For a foot pedal irrigator for ophthalmic surgery according to an embodiment of the present application, comprising:

[0032] The syringe fixing support 1 is made of plastic material: one side is concave to form a syringe placing groove 11 for placing the syringe therein, the two sides of the syringe placing groove 11 are provided with syringe handle grooves 12 for clamping the outer handle of the syringe, and the syringe handle groove 12 is a circular plane: when the syringe is placed, it is rotated around the long axis to make the handle of the syringe slide into the syringe handle groove 12 and be fixed; this structure can prevent the syringe from falling after being placed.

[0033] The other side of the syringe fixing support 1 is provided with a squeeze air bag 2, one end of the squeeze air bag 2 abuts against the syringe piston, and the other end is connected with a foot pedal air charging element 4 through a hollow air tube 3 made of rubber material;

[0034] The outer side of the syringe support is movably provided with a fixing ring 13, and the fixing ring 13 can fix the syringe support to a surgical microscope;

[0035] The foot pedal air charging element 4 is provided with an air charging pedal 41, an air discharging pedal 42 and an air charging bag 43, the air charging bag 43 is provided with a one-way valve 431, when the air charging pedal 41 is stepped down, air enters the squeeze air bag 2 from the air charging bag 43 through the air tube 3, and when the air discharging pedal 42 is stepped down, air flows back into the air charging bag 43 from the squeeze air bag 2.

[0036] Specifically, the air charging bag 43 is provided with a one-way valve 431 at each end, when the air charging pedal 41 is stepped down, the one-way valve 431 close to the air tube 3 is opened, and then gas enters the squeeze air bag 2 from the air tube 3, and further deforms the squeeze air bag 2 to push against the syringe piston. When the air charging pedal 41 is released, the air charging bag 43 gradually recovers from the compressed state to the inflated state, and external air enters the air charging bag 43 through the other one-way valve 431; because the pressure of the air charging bag 43 is lower than the outside at this time, the gas just entering the air charging bag 43 will not further enter the squeeze air bag 2. When the air charging pedal 41 is stepped down, the gas in the air charging bag 43 is squeezed and enters the squeeze air bag 2 through the air tube 3, and because of the cooperation of the two one-way valves 431 of the air charging bag 43, external air can be continuously sent into the squeeze air bag 2.

[0037] The working principle of the air discharging pedal 42 is that the air discharging pedal 42 is located between the air charging bag 43 and the air tube 3, and the air discharging pedal 42 controls a part of the air tube 3. Specifically, the air discharging pedal 42 has a cavity below, the cavity has a discharging hole 422 and a shutter 421 which are in communication with the outside, and the shutter 421 is linked with the air discharging pedal 42. When the air discharging pedal 42 is stepped down, the shutter 421 moves to make the discharging hole 422 communicate with the outside, and the air pressure in the whole system is gradually the same as the outside, so that the squeeze air bag 2 is reset and the squeeze on the syringe is released, and then the syringe can be removed. During the air charging process, because the pressure in the system is higher than the outside, the shutter 421 can be pushed to seal the discharging hole 422.

[0038] There is also a spring below the air discharging pedal 42, which pushes the air discharging pedal 42 to maintain the initial state, and better seals the discharging hole 422 by the shutter 421.

[0039] Optionally, the flushing head 5 is sleeved on the nipple of the syringe, is foldable, and is different from a general syringe needle in that the end is not beveled and the flushing head 5 is made of metal as a whole and can be provided with internal threads to firmly fix the syringe through the threads to prevent the flushing head 5 from being accidentally flushed out.

[0040] In some embodiments, the reminding device is arranged in the syringe fixing support 1 and comprises a push rod, a spring and a sound-producing sheet, the push rod extends from the side of the syringe placing groove 11, the push rod is pushed to knock the sound-producing sheet to produce sound when the syringe piston moves, and the spring pulls the push rod to reset.

[0041] Optionally, the syringe fixing support 1 is provided with a threaded hole, the fixing ring 13 is provided with a threaded column matched with the threaded hole in a threaded manner, and the threaded column is further provided with a fastening nut 131. Through the scheme, the syringe fixing support 1 can be replaced with different specifications to adapt to different surgical microscope structures, when in use, the relative angle between the fixing ring 13 and the syringe fixing support 1 is determined, then the fastening nut 131 is rotated to be clamped, and the fixing ring 13 and the syringe fixing support 1 will not rotate relative to each other, for this, the direction in which the threaded hole is screwed is set as the direction in which the syringe fixing support 1 moves downward, and when in use, the fastening nut 131 can effectively control the tendency of the syringe to swing downward.
