Eye speculum convenient to disassemble and assemble for ophthalmology

Abstract

The invention relates to the technical field of medical instruments, and relates to an eye speculum convenient to disassemble and assemble for ophthalmology. The product comprises a supporting base, side plates are fixedly connected to the left side and the right side of the front face of the supporting base, and a limiting mechanism is fixedly installed at the top end of the side edge plate and comprises a first connecting rod, the first connecting rod is hinged to the surface of the side edge plate, the surface of the first connecting rod is sleeved with a sliding sleeve, a locking mechanismis fixedly installed at the top end of the sliding sleeve, and the locking mechanism comprises a second connecting block and a second rotary sleeve. According to the invention, the locking mechanismand an adjusting mechanism are arranged; in the use process, the first rotary sleeve is rotated; when the first rotary sleeve rotates, a second rotary shaft moves on the inner wall of the first rotarysleeve, and when the second rotary shaft moves to a certain position, the second rotary shaft is separated from the inner wall of the first rotary sleeve, so that the second rotary shaft is conveniently pulled out, an eyelid opening frame is disassembled, the eyelid opening frame is conveniently and independently replaced, and meanwhile, the disinfection rate of workers on the eyelid opening frame is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a detachable eyelid speculum used in ophthalmology. Background technique [0002] The eyelid speculum is an instrument used to open the patient's eyelids during eye surgery to facilitate the operation. It is beneficial to expand the surgical field and is an indispensable medical device in ophthalmic surgery. The shape of the eyelid speculum is mostly V-shaped or Y Shaped, including the support arm and the eyelid hook, the rear ends of the two support arms are combined into a hand-held part, and the front end is two symmetrically arranged eyelid hooks. The eyelid hooks are generally arranged in a horizontal L-shaped structure, and The part is inserted into the eye socket to fix the eyelids, and the horizontal part is used to limit the depth of the vertical part extending into the eye socket, so as to prevent the vertical part from causing damage to the eyeball.

Problems solved by technology

[0004] The purpose of the present invention is to provide an easy-to-disassemble eyelid speculum used in ophthalmology to solve the problem that the structure of the eyelid speculum used in hospitals on the market cannot be disassembled, and at the same time, the eyelid frame cannot be opened. After the instrument is used, it cannot be disassembled and assembled, and its disinfectant is inconvenient. It needs to be held by the medical staff for a long time when it is used. The burden of personnel is not conducive to the development of medical work
