Description

Technical Field

[0001] The utility model relates to the technical field of corneal contact lens equipment, in particular to a corneal contact lens fixing device. Background Art

[0002] Corneal contact lenses, commonly known as contact lenses, are lenses that are directly attached to the surface of the cornea to correct vision or protect the eyes. Before wearing a corneal contact lens, its surface must be made sure to be smooth and flat. If there are contaminants such as dust, particles or lens fragments, it will produce a foreign body sensation after wearing and may even damage the user's cornea. Therefore, after the corneal contact lens is manufactured, it must be fixed for testing. In the existing technology, it is difficult to fix the corneal contact lens. Since the corneal contact lens material is relatively soft, it is difficult to fix it with a clamp. At the same time, there is a lack of testing for the fixation of multiple corneal contact lenses.

[0003] For example, the authorized patent document with application number CN201720663734.7 discloses a contact lens fixing device, the main body of which is a fixing ring with four symmetrical trapezoidal side legs around it. The bottom edge is curved, and the arc matches the arc of the scleral three-channel cannula used in vitrectomy surgery, making it easy to fix on the side of the cannula and prevent the ring from moving outward; the side legs are also curved, and the angle formed is used to avoid the puncture cannula during vitrectomy surgery; the four symmetrical side legs play a role in balancing forces in all directions; the multiple arc designs increase the contact surface with the conjunctiva, making it more stable and less likely to slide. This utility model can fix the contact lens fixing ring to the surface of the eyeball without suturing, and will not cause damage to the patient's eyeball; during surgery, it is only necessary to place the fixing device on the corneal surface, which reduces the number of operating steps and shortens the operation time; it has good centering and good effect in fixing the corneal contact lens; the materials used are safe and low-cost, which is conducive to clinical promotion and use; the design is simple and delicate, and the product is beautiful and elegant.

[0004] The above patent has the problem that since the material of the corneal contact lens is relatively soft, it is difficult to fix it with a clamp, so we need to provide a corneal contact lens fixing device. Utility Model Content

In addition, multiple corneal contact lenses can be placed and fixed on multiple arc seats, which facilitates the detection of the corneal contact lens surface by the detection component. The motor is started to drive the output rod to rotate, and the output rod drives the turntable to rotate, thereby controlling the rotation and adjustment of the multiple fixed corneal contact lenses, thereby solving the problems raised in the above-mentioned background technology.

[0030] The fixing member 3 includes a turntable 31 disposed within the tank body 2. An annular tube 32 is embedded within the turntable 31. The top of the annular tube 32 is connected to a plurality of air pipes 33. The tops of the plurality of air pipes 33 all pass through the top of the turntable 31 and are connected to an arc-shaped seat 34. The arc-shaped seat 34 has an air groove 35 inside that is connected to the air pipes 33.

At this time, the concave surface of the corneal contact lens is placed on the arc seat 34 to adsorb the corneal contact lens, thereby fixing the corneal contact lens. In addition, multiple corneal contact lenses can be placed and fixed on multiple arc seats 34, which is convenient for the detection of the corneal contact lens surface by the detection component 8. The motor 5 is started to drive the output rod 6 to rotate, and the output rod 6 drives the turntable 31 to rotate, thereby controlling the rotation adjustment of the multiple fixed corneal contact lenses.

[0034] A motor 5 is embedded in the bottom of the base 1, an output rod 6 is installed at the output end of the motor 5, and the top of the output rod 6 is fixedly mounted on the bottom of the turntable 31;
