The core of the utility model is to provide an eyeball fixing and measuring device, which can mark an operation position while fixing an eyeball, and improve the accuracy and efficiency of operation.
In order to make those skilled in the art better understand the technical solution of the present invention, the eyeball fixation measuring device of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The eyeball fixation measuring device provided by the utility model comprises a fixing ring 1, a positioning contact pin 2, an operation bracket 3 and other structures which are relatively fixed into a whole; fig. 1 to fig. 3 are schematic views of an eyeball-fixation measuring device of the present invention at three different angles.
The fixing ring 1 is a spherical ring and can be attached to the outer surface of an eyeball; the fixing ring 1 is equivalently cut on a spherical surface to form a section of closed circular ring structure, and the outer surfaces of eyeballs in the shape are consistent so as to be fully contacted as far as possible; the upper edge and the lower edge of the fixing ring 1 are both circular, the radiuses of the two circles are different, the upper edge is a small circle, and the lower edge is a large circle.
The positioning contact pin 2 is arc-shaped long, one end of the positioning contact pin 2 is fixed on the large circular edge of the fixing ring 1, and the other end of the positioning contact pin 2 freely extends and is not fixed; the positioning contact pin 2 extends along a meridian of the spherical surface, and the rotation axis of the fixing ring 1 is a diameter of the meridian.
The positioning contact pin 2 and the fixing ring 1 are positioned on the same spherical surface, so that the positioning contact pin 2 and the fixing ring 1 can synchronously contact with the eyeball; the positioning contact pin 2 is provided with positioning scales, and the positions of eyeballs are marked through the scales. The positioning contact pin 2 can be calibrated in millimeters (mm) or in other specifications as required, but the total length of the positioning contact pin needs to ensure the distance required by the operation.
When the fixing ring 1 contacts the outer surface of the eyeball, the large circular edge of the fixing ring 1 is usually required to be positioned at the junction between the cornea and the sclera of the eyeball, for the operation of injecting medicine into the eyeball, a puncture needle is generally required to be inserted 3.5-4 mm behind the junction edge of the cornea and the sclera, and the position of the needle is calibrated by utilizing the positioning contact pin 2, so that an operator is assisted to determine the needle inserting position more accurately.
The operation bracket 3 is fixed on the fixing ring 1 for operation and holding; the operation support 3 extends upwards, and the operator holds the operation support 3, avoids hand and solid fixed ring 1 contact, is controlled solid fixed ring 1 contact eyeball by operation support 3.
