Corneal foreign body draw-out spoon

Abstract

A corneal foreign body draw-out spoon is an apparatus applied for drawing out a corneal foreign body, which can reach the purpose of conveniently, thoroughly and safely drawing out the corneal foreign body. The corneal foreign body draw-out spoon comprises a spoon part, a connecting rod and a handheld section. The spoon part comprises a semicircular spoon and a spoon tip formed by the tapering of the top end of the semicircular spoon, and a transition part between the semicircular spoon and the spoon tip is a shoveling part with the two sides being sharp. The connecting rod connects the spoon part with the handheld section, and the angle between the connecting rod and the spoon part is 30 degrees. The entire corneal foreign body draw-out spoon is made of stainless steel, can be disinfected by high temperature and can be used repeatedly. An operator can pinch the handheld section by an index finger and a thumb and aligns the head of the spoon with a corneal foreign body under a slit lamp; as for a smaller foreign body, the operator can be directly pick out the foreign body through the spoon tip; and as for a bigger foreign body or a foreign body which has turned to a rust ring, the operator can first stir to loosen the foreign body, then adjust the angle of the corneal foreign body draw-out spoon, and scrape the remaining foreign body or rust ring through the shoveling part at the side face or the spoon part at the back end of the spoon.

Description

technical field [0001] The patent relates to a device for removing corneal foreign bodies, which achieves the purpose conveniently, thoroughly and safely. Background technique [0002] Corneal foreign body is a common disease in ophthalmology. Although there are many instruments to solve the problem at present, common needles are commonly used to pick it up clinically. The reason is that the instruments are too complicated and impractical. But ordinary needles have their obvious disadvantages in the operation process. The real difficulty in picking out corneal foreign bodies is not the foreign body itself, but the infiltration foci formed after it stays in the cornea for a period of time, especially the rust ring. It must be completely removed, otherwise, on the one hand, it will delay corneal healing and increase the risk of infectious keratitis; on the other hand, it will affect the transparency of the cornea and damage vision. Under the microscope, compared with the in...

Problems solved by technology

It must be completely removed, otherwise, on the one hand, it will delay corneal healing and increase the risk of infectious keratitis; on the other hand, it will affect the transparency of the cornea and damage vision

Under the microscope, compared with the infiltration foci left by foreign objects, the tip of the traditionally used needle appears too small, and the operation is time-consuming and laborious
