Description

Technical Field

[0001] This utility model relates to human daily necessities, and more particularly to medical devices, especially an ophthalmic eyelash trimming device. Background Technology

[0002] Most intraocular surgeries in ophthalmology require eyelash trimming before surgery; however, the trimmed eyelashes cannot be collected and easily fall into the patient's eye, causing discomfort and potentially infection. To prevent this, clinicians apply eye ointment to the scissor blades to adhere the trimmed eyelashes. However, this method has significant drawbacks: the ointment adheres to the eyelashes, making trimming difficult, increasing the workload for medical staff, consuming considerable time, and complicating subsequent cleaning and disinfection; furthermore, the trimmed eyelashes can fall onto the floor, causing contamination.

[0003] In the prior art, patent publication CN222494565U discloses an eyelash trimming device for ophthalmic surgery. This device uses a built-in suction pump to suction during eyelash trimming, preventing eyelash debris from falling out. While this device effectively solves the problem of handling eyelash debris, it still has the following drawbacks:

[0004] The device has a built-in suction pump, which makes the device too expensive and difficult to use widely.

[0005] The device has built-in electronic equipment, making it very difficult to clean and disinfect, thus limiting its application in the medical field.

[0006] The device's built-in suction pump increases its weight, making it difficult for medical staff to use. The excessive weight also makes it unsuitable for delicate procedures like those involving the eyes.

[0007] It is difficult to observe the trimming position when trimming eyelashes, which can easily lead to accidents and injuries to patients. Utility Model Content

[0008] The purpose of this invention is to provide an ophthalmic eyelash trimming device that solves the technical problems of high cost, difficulty in cleaning and disinfection, heavy weight, and difficulty in operation in the prior art.

[0009] An ophthalmic eyelash trimming device includes a base with two vertical rods on either side of the top of the base, the top ends of which are connected by a crossbar. It also includes a movable device comprising a hair collection box with an opening at the top and a connecting post at the bottom. A connecting hole is provided on the base, and the connecting post is slidably connected within the connecting hole. A negative pressure interface is provided on the hair collection box, communicating with the interior of the box. An upper blade is located at the bottom of the crossbar, and a lower blade is located at the top of the hair collection box, with the cutting edges of the upper and lower blades corresponding. The device also includes a first handle and a second handle. The first handle is fixed to the bottom of the base, and the second handle is rotatably connected to the base via a pivot. The top end of the second handle is hinged to the connecting post. Sliding grooves are provided on the two vertical rods, and sliders are provided on both sides of the hair collection box, slidably connected to the corresponding sliding grooves. Finally, a connecting tube is included, one end of which is connected to the negative pressure interface.

[0010] Furthermore, the other end of the connecting pipe is connected to a wall-mounted negative pressure suction device.

[0011] Furthermore, it includes an external negative pressure device, with the other end of the connecting pipe connected to the external negative pressure device.

Detailed Implementation

[0028] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention. Example

[0029] like Figures 1 to 6 As shown, this embodiment provides an ophthalmic eyelash trimming device, including a base 1, with a vertical rod 2 fixedly installed on each of the two sides of the top of the base 1, and the top ends of the two vertical rods 2 are fixedly connected to each other by a horizontal rod 3.

[0030] The device includes a movable device 4, which includes a hair collection box 401. The top of the hair collection box 401 has an opening, and a longitudinal connecting column 403 is fixedly connected to the bottom of the hair collection box 401. A longitudinal connecting hole 101 is opened on the base 1. The connecting column 403 is slidably connected in the connecting hole 101, so that the connecting column 403 drives the hair collection box 401 to move along the axial direction of the connecting hole.

[0031] The hair collection box 401 is made of transparent material so that the amount of eyelash debris in the hair collection box 401 can be observed.

[0032] The bottom of the crossbar 3 is provided with an upper blade 301, and the top of the hair collection box 401 is provided with a lower blade 404. The cutting edges of the upper blade 301 and the lower blade 404 correspond to each other.

[0033] It includes a first handle 5 and a second handle 6. The first handle 5 is fixed to the bottom of the base 1, and the second handle 6 is rotatably connected to the base 1 through a pivot. The top of the second handle 6 is hinged to the connecting post 403. When the second handle 6 is pressed down, the second handle 6 rotates relative to the base 1 around the pivot. Then, through the lever principle, the connecting post 403 hinged to it is lifted up. The connecting post 403 drives the hair collection box 401 to be lifted up, thereby causing the upper blade 301 and the lower blade 404 to come into contact with each other, so as to achieve the shearing effect.

[0034] Two vertical rods 2 are respectively provided with a sliding groove 201 on one side of their opposite sides. The hair collection box 401 is provided with sliders on both sides. The sliders are slidably connected to the sliding groove 201 on the corresponding side, so that the hair collection box 401 moves along the sliding groove 201 when it is lifted up, thereby making the contact position of the cutting edge of the upper blade 301 and the lower blade 404 more precise.

[0035] The eyelash collection box 401 is equipped with a negative pressure interface 402, which is connected to the interior of the eyelash collection box 401. It includes a connecting pipe 8, which is a lightweight flexible tube. One end of the connecting pipe 8 is connected to the negative pressure interface 402, and the other end is connected to an external negative pressure device 9. The opening of the eyelash collection box 401 is close to the cutting position of the blade. The external negative pressure device 9 creates negative pressure inside the eyelash collection box 401, thereby drawing the cut eyelash debris into the eyelash collection box 401. Simultaneously, a filter screen 7 is installed inside the negative pressure interface 402 to prevent eyelash debris from leaving the eyelash collection box 401.

[0036] The eyelash trimmer and the negative pressure device are designed separately and connected to each other through a connecting tube 8. This allows the eyelash trimmer to attract eyelash debris without affecting its normal operation. Furthermore, the eyelash trimmer adopts a scissor-like structure similar to an eyelash curler, making it easier for medical staff to see the trimming position, improving operational efficiency and reducing the occurrence of accidents. Example

[0037] This embodiment is a preferred solution of Embodiment 1. The other end of the connecting tube 8 is connected to the wall-mounted negative pressure suction device to directly obtain negative pressure for eyelash suction. Wall-mounted negative pressure suction devices are widely used in hospitals. The connecting tube 8 can be directly connected to it to obtain negative pressure, eliminating the need to carry an external negative pressure device 9 and making operation more convenient.

[0038] The cross-section of the outer wall of the negative pressure connection port is stepped, which allows for the connection of various pipe diameters 8, thus expanding the types of negative pressure devices that can be adapted.

[0039] The opening of the hair collection box 401 is equipped with a one-way flap, which opens inwards towards the inside of the hair collection box 401. The one-way flap is connected to the side wall of the opening of the hair collection box 401 via a pivot, and a bushing spring is installed on the pivot. The spring force keeps the one-way flap closed when there is no external force. When negative pressure is applied, the one-way flap opens inwards towards the inside of the hair collection box 401, allowing eyelash debris to enter the hair collection box 401. After the negative pressure is closed, the one-way flap closes again under the action of the spring, thus preventing eyelash debris from falling out of the hair collection box 401.

[0040] Except for the connecting tube 8, all parts of this embodiment are designed for single use. The main body is made of plastic and is packaged aseptically at the factory. It is ready to use immediately after opening, and each person uses one pair of clippers. It is discarded after use. When discarding, the eyelash clippings are thrown away together with the clippers to minimize cross-infection. It is especially suitable for the treatment of eyes in patients with various infectious diseases.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
