Abstract
The utility model relates to a hand eye keratometer. A handle 4 is connected with the lower end of an in-concave support plate; the center of the support plate is opened with an observation hole 2; a light source 3 is fixed around the in-concave support plate; one side of the in-concave support plate is equipped with contrast signs 5 using the observation hole as symmetric center, and the light source and the central symmetric contrast signs are all arranged on the concave side of the in-concave support plate. The surface with signs faces toward a patient, but the doctor observes the patient from the observation hole and checks the sign reflected from the eye ball is symmetric with the original sign in order to determine whether the corneal curvature meets the requirements. The apparatus has no side effect, is easy to be carried and provides convenience for the external practice medicine of doctors.
Description
This utility model is to be used for behind the eyes operation on cornea or the appropriate inspection adjustment instrument of corneal wound stitching after the ocular injury.
At present, the corneal curvature instrument exists that volume is big, price is expensive and the defective of complicated operation, and the Plocid ring is inconsistent with cornea physiology curvature.
The purpose of this utility model is a kind of hand-held eyes corneal curvature somascope of development, this somascope can become numerous and diverse device hand-held inspection apparatus simple in structure, and making that observation is convenient, simple to operate, diagnosis is accurate, the curvature of this instrument conforms to anterior corneal surface physiology curvature.
This utility model is made up of concave shaped gripper shoe 1, observation port 2, light source 3 and handle 4.Handle 4 is connected the lower end of concave shaped gripper shoe 1.Have an observation port 2 at the positive center of concave shaped gripper shoe 1, light source 3 be fixed on concave shaped gripper shoe 1 around on, one side of concave shaped gripper shoe 1 is shaped on from observation port 2 and is centrosymmetric correlation marker 5, and light source 3 and centrosymmetry correlation marker 5 are all on concave surface one side of concave shaped gripper shoe 1.Have during work sign one facing to the patient, whether whether the doctor observes patients from opposite side observation port 2, and from the sign that eyeball reflects back see and former sign 5 symmetries meet the requirements in order to judge corneal curvature, and in time adjust the tight program of stitching.
This utility model is simple in structure, be convenient to operation and promote, the concave curvature of concave support plate conforms to cornea physiology curvature, so can accurately reflect the actual curvature that is sewn cornea when checking, and cost is low, practicality is wide, be easy to carry, and especially practises medicine for the remote districts of going to the countryside and provides convenience.And this somascope is under observation to patient's eye nonirritant, radiationless effect.
Fig. 1 is a front view of the present utility model, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is a rearview of the present utility model, and Fig. 4 is the front view of embodiment two, and Fig. 5 is the front view of embodiment three.
Embodiment one: present embodiment is made up of concave shaped gripper shoe 1, observation port 2, light source 3 and handle 4.Handle 4 is connected the lower end of concave shaped gripper shoe 1, the observation port 2 that to have a diameter at the positive center of concave shaped gripper shoe 1 be 5mm-10mm, on the concave shaped gripper shoe 1 around on light source 3 is housed, correlation marker 5 is evenly distributed on the concave surface of concave shaped gripper shoe 1, and coexists on the side with light source 3.Correlation marker 5 is and the multi-turn circle of observation port 2 concentricity symmetrical distributions that concave shaped gripper shoe 1 is square.The concavity of concave shaped gripper shoe 1 is identical with cornea physiology curvature.
Embodiment two: what present embodiment and embodiment one were different is to be correlation marker 5, and correlation marker 5 is that other composition is identical with embodiment one with annexation with many rays of observation port 2 centers for distributing symmetrically and evenly.
Embodiment three: what present embodiment and embodiment one were different is correlation marker 5, and correlation marker 5 is to be equally distributed many vertical lines of centrosymmetry with observation port 2, and other composition is identical with embodiment one with annexation.
