Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a negative pressure suction device for ophthalmology. Background Technology

[0002] Negative pressure aspirators are crucial devices in ophthalmic surgery and treatment. Traditional negative pressure aspirators are mostly general-purpose and not specifically designed for the unique needs of ophthalmology. However, in actual clinical ophthalmology work, precise suction of intraocular fluids (such as aqueous humor and exudate) and tissues (such as the cloudy lens in cataract surgery) is frequently required.

[0003] Currently, when using traditional negative pressure suction equipment for ophthalmic surgery, the suction tube is mostly operated by medical staff holding it by hand. This method can easily lead to fatigue of medical staff during long ophthalmic surgeries, which may affect the stability of the suction operation. Moreover, in some delicate ophthalmic surgeries, even slight shaking of the suction tube may cause damage to the eye tissues, making it inconvenient to use overall.

[0004] Therefore, this application provides a negative pressure suction device for ophthalmology to meet the needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a negative pressure suction device for ophthalmology, so as to solve the safety hazards that exist when medical staff continuously hold the suction tube to perform negative pressure suction in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A negative pressure suction device for ophthalmology includes a body, a collection container is elastically installed inside the body, a negative pressure tube is connected to the top side of the body, a suction tube is installed at the end of the negative pressure tube away from the body, and a suction plate is fitted to the suction tube.

[0008] The suction plate is a C-shaped frame structure adapted to the periphery of the human eye. The outer edge of the suction plate is provided with a fixing part, and a guide frame is slidably installed on the suction plate. The end of the suction tube away from the negative pressure tube is fixed to the guide frame, and the end of the suction tube is provided with a suction port facing the center of the suction plate.

[0009] Optionally, the bottom of the machine body is provided with a base, and a movable plate is elastically installed on the upper surface of the base, the movable plate being supported on the bottom of the collection tank.

[0010] Optionally, the collection tank is provided with graduations.

[0011] Optionally, a vacuum negative pressure pump and a control knob are installed on the top of the machine body, and multiple levels of negative pressure suction intensity are provided.

[0012] Optionally, the vacuum negative pressure pump is connected to the collection tank through a filter element installed at the top of the machine body, and the negative pressure pipe is connected to the vacuum negative pressure pump through the collection tank.

[0013] Optionally, a handle is installed on the side of the body.

[0014] Optionally, the upper surface of the suction plate is provided with a groove, a slider is slidably installed in the groove, one end of the guide frame is fixed to the slider, and the other end is provided with an insertion hole for fixing the end of the suction tube.

[0015] Optionally, at least two grooves are provided, located on the upper and lower sides of the suction plate respectively, to correspond to the upper and lower eyelids of the human eye.

[0016] Optionally, a connector is provided at the end of the suction tube away from the suction port, and the connector is interference-fitted onto the port of the negative pressure tube away from the machine body.

[0017] Optionally, the fixing part is a bio-adhesive tape surrounding the outer edge of the suction disc.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects:

[0019] In the above solution, the vacuum negative pressure pump is controlled by a control knob installed on the top of the machine, which can realize multiple levels of negative pressure suction. This allows for more precise adjustment of the negative pressure value, making it easier to adapt to different procedures in ophthalmic surgery (such as removing tiny tissue fragments from the eye and aspirating intraocular exudate) that require different negative pressure intensities, thus providing flexibility in use.

[0020] By setting graduations on the collection container, medical staff can intuitively see the amount collected inside. The collection container is also elastically supported in the body of the machine by a movable plate, making it easy to remove and install, reducing surgical interruption time and improving surgical efficiency.

[0021] By setting up a suction plate to fit the periphery of the human eye, and thanks to the guide frame that slides on the suction plate, the suction tube is fixed on the guide frame, which allows the suction tube to be stably placed in the appropriate position on the patient's eye. This eliminates the need for medical staff to hold the tube continuously, reducing the risks caused by unstable hand-holding and improving the precision of the surgery.

[0022] In summary, this device is not only easy to carry and has multiple settings, but also allows for quick assembly and disassembly of the collection container and convenient placement of the suction tube over the patient's eye. It does not require continuous hand-held operation by staff, and the overall performance is excellent. Attached Figure Description
