Description

Expanding device for clinical ophthalmic surgery

The invention belongs to the technical field of medical instruments, and relates to a dilator for clinical ophthalmic surgery.

Background

When carrying out the surgery operation of eye, need use the eye speculum, the eye speculum is the utensil that is used for strutting patient's eyelid so that the operation when an eye operation, is favorable to opening wide art wild, is indispensable medical instrument among the eye operation, and the theory of operation of eye speculum is similar to the drag hook among the surgery operation, and application method is: the two support arms are pressed towards the middle to enable the two eyelid opening hooks to be close to each other, then the eyelid opening hooks are placed above the eyeballs of the patient, the support arms are lightly released, and at the moment, the upper eyelid and the lower eyelid are simultaneously expanded by the two eyelid opening hooks.

In the operation process, the patient keeps opening the eye state for a long time, can produce a large amount of tears, can accumulate waste liquid such as flush fluid and a little bloody water in the conjunctival sac in addition operation process, and the persistence of waste liquid not only can influence medical personnel's sight, still can cause secondary infection to the patient, influences patient's later stage and resumes.

In order to solve the problems, the Chinese patent (publication No. CN210612170U) discloses a clinical ophthalmological operation expanding and supporting device, which comprises a spectacle frame, wherein two eyelid expanding and supporting arc plates are arranged in the spectacle frame, through holes are formed in opposite surfaces of the two eyelid expanding and supporting arc plates, the end parts of the two eyelid expanding and supporting arc plates are communicated with a side surface close to a liquid injection pipe through a same three-phase shunt pipe, the bottom end of the liquid injection pipe is fixedly connected to the front surface of the spectacle frame, a micropump and a base are fixedly connected to the front surface of the spectacle frame respectively, a suction pipe is movably connected to the micropump, the front surface of the base is fixedly connected with one end of a metal hose, and a lighting lamp is arranged at the other end of the metal hose.

Above-mentioned scheme is though can collect waste liquid and tear, but its collection rate is slow, needs medical personnel to pump with handheld straw always, consumes the manpower, very influences the operation process, and the device uses inconveniently, is difficult to carry out the hook to upper and lower eyelid, expands and props to be difficult to assist with the hand, very easily harms patient's eyeball in the use, and the device can't be fixed patient's head simultaneously, has the limitation.
