Abstract

The utility model discloses a medical painless ophthalmostat in clinical use in ophthalmology department, which is an important assistant tool for ophthalmologic operations. The ophthalmostat comprises two parts, namely an ophthalmostat for clinical operation and an ophthalmostat for light shielding. An operation window (3) slightly bigger than the iris of human eyes is arranged in the geometric center of the main structure (1) of the ophthalmostat for clinical operation, and the operation window (3) corresponds to the iris in position; and two eyelid withholding structures (2) are further arranged on the main structure (1) for withholding the motion of the upper and lower eyelids and keeping the eyelids in an open state. A semi-transparent photosensitive point is arranged in the geometric center of the main structure of the ophthalmostat for light shielding, and the photosensitive point corresponds to the center of the pupil; and the structure of the rest parts of the ophthalmostat for light shielding is the same as that of the ophthalmostat for clinical operation. The painless ophthalmostat is made of non-transparent nontoxic flexible medical material, so that the light is shielded to ensure that eyes are not stimulated by strong light and prevented from being damaged.

Description

Painless ophthalmostat

Technical field

This utility model relates to a kind of ophthalmostat that is used for the clinical treatment ophthalmic.

Background technology

When the treatment ocular disease (as: corneal transplantation, crystal transplanting etc.), need make eyelid remain open configuration, therefore need this medical auxiliary apparatus of ophthalmostat to finish corresponding clinical operation process.The existing problem of present ophthalmostat comprises:

1) ophthalmostat of metal material is though energy relative fixed eyeball lacks flexible patient's the misery that causes easily.

2) though existing various ophthalmostat can play fixation to eyeball, the action of uncontrollable eyelid will usually can bring many unnecessary miseries to the patient by the fixing eyelid of other medical apparatus and instruments.

The utility model content

The utility model proposes a kind of ophthalmostat that is used for auxiliary ophthalmologic operation.This ophthalmostat has following characteristics:

1) healthy, comfortable, safety.Eyes are the crucial non-renewable organs of human body, and agent structure of the present utility model adopts nontoxic flexible material to make, and it is hereby ensured in use health of user, comfortable and safe;

2) has the eyelid supporting construction.This utility model adopts distinctive eyelid supporting construction just can support eyelid on structural design, prevents from that eyelid from blinking to cover eyeball, and without any need for other assistive devices, has alleviated patient's misery in the operation process greatly;

3) eyeball guide structure.The distinctive fill-in light guiding port of this utility model guarantees in the process of ophthalmologic operation, and the patient can consciously keep eyes not rotate (locking a certain target).

This utility model has clinical operation ophthalmostat and shading two ingredients of ophthalmostat, and it is made material and adopts light tight nontoxic flexible medical material (as: silica gel), thereby can not cause accidental injury to eyeball.Clinical operation matches with inboard radian of ophthalmostat agent structure and eyeball, and agent structure both sides design up and down has the eyelid barrier structure, can support eyelid, prevents the influence of blinking operation being caused.Central authorities in agent structure have the action pane that is slightly larger than the human eye iris, are used to carry out ophthalmologic operations such as corneal transplantation.

In addition, because outside light source distance eyes are very near in ophthalmic surgical procedures, in order to reduce the stimulation of light to eyes, so need carry out shading treatment to patient's other eyes, this utility model comprises agent structure, eyelid barrier structure and sensitivity speck for the patient has designed the shading ophthalmostat.This is in order to make two eyes of measured can both watch the direction that light is arranged attentively, thereby avoids the rotation of eyeball.

Employing the utlity model has following advantage:

1) ophthalmostat of the present utility model is the important aid of ophthalmologic operation, the health that this holder adopts light tight flexible non-toxic biocompatible material (as: silica gel) to make can to guarantee the patient, comfortable and safe;

2) this utility model (auxilliary ophthalmostat) can avoid eyes to be subjected to the stimulation or the damage of high light effectively in operation process;

3) the translucent aperture in ophthalmostat of the present utility model centre can play by the guiding function of patient's sight, makes that patient's eyes are basic in operation process to keep motionless;

4) eyelid supporting construction of the present utility model can make patient's eyes under the situation of not using any other assistive device, is in open configuration all the time, to guarantee carrying out smoothly of operation process.

The specific embodiment

This utility model comprises two parts, clinical operation ophthalmostat and shading ophthalmostat, and wherein corresponding to being treated eyeball, shading uses ophthalmostat corresponding to non-treatment eyeball to clinical operation with ophthalmostat.

As shown in Figure 1 and Figure 2, clinical operation adopts light tight flexible non-toxic biocompatible material (as silica gel) with the making material of ophthalmostat, the radian that the inboard radian of its agent structure 1 and human eye eyeball are had matches, agent structure 1 and eyelid barrier structure 2 fuse, two eyelid barrier structures 2 lay respectively at the both sides up and down of agent structure 1, and along the surface of agent structure 1 to outer process, can suppress the influence of blinking operation being caused of eyelid.In the geometric center position of agent structure 1, have the action pane 3 that is slightly larger than the human eye iris, be used to carry out ophthalmologic operations such as corneal transplantation.

As shown in Figure 3, Figure 4, shading is adopted light tight flexible non-toxic biocompatible material (as silica gel) with ophthalmostat, the radian that the inboard radian of its agent structure 4 and human eye eyeball are had matches, agent structure 4 and eyelid barrier structure 5 fuse, two eyelid barrier structures 5 lay respectively at the both sides up and down of agent structure 4, and along the surface of agent structure 4 to outer process, can suppress the influence of blinking operation being caused of eyelid.In the geometric center position of agent structure 4, reserve a translucent sensitivity speck 6, the incident ray direction that requires the patient always to watch sensitivity speck attentively during use, thus can avoid the rotation of eyeball effectively.
