Abstract
The utility model discloses a kind of corneal foreign matter removing device that can be used for rejecting the foreign body on patient's cornea, belong to technical field of medical instruments.A corneal foreign matter removing device, comprises that piston cylinder and one end are arranged on the piston rod in piston cylinder, is fixed with the suction pipe being communicated with cavity in piston cylinder on piston cylinder, and piston rod is positioned on one end of piston cylinder and is fixed with magnetic tip.This utility model utilizes magnetic tip on piston rod by the magnetic conductive metal foreign body sucking-off in patient's cornea, and foreign body is entered in piston cylinder by suction pipe under magneticaction, thereby makes foreign body depart from patient's eyeball surface; When the foreign body in patient's cornea does not have magnetic conductivity, can use suction pipe that foreign body is chosen, the piston cylinder of then holding with a firm grip on the other hand, another pulls moving piston rod foreign body is drawn in piston cylinder by suction pipe.This utility model can disposablely complete foreign body eliminating and depart from the work of eyeball, is particularly useful for rejecting magnetic foreign body.
Description
Technical field
This utility model relates to a kind of corneal foreign matter removing device that can be used for rejecting the foreign body on patient's cornea, belongs to technical field of medical instruments.
Background technology
Corneal foreign body is the more common a kind of disease of ophthalmology outpatient service, corneal foreign body generally be take metallic foreign body as main, usually have some foreign body incarcerations corneal stroma, at anterior corneal surface without exposing, this foreign body is easy to reject and does not thoroughly even reject, need to through after a while voluntarily outside row could reject totally, because iron foreign body and some other metallic foreign bodies can remain rusty stain after staying for some time in cornea, this will affect the healing of wound.
Publication number is that the Chinese utility model patent that CN2375278Y, name are called " disposable multifunction cornea foreign body needle " discloses a kind of corneal foreign matter removing device, it comprises with the needle stand of inner chamber and is plugged on the hollow needle body of curved arc shape on needle stand one end, the outer face of hollow needle body is the inclined-plane of a blunt circle, the other end of needle stand is plugged with liquid storage pipe, in the inner chamber of liquid storage pipe, piston rod is housed.In use, utilize the hollow needle body of this device for eliminating to choose foreign body, in choosing process, can inject appropriate antibiotic eye drop and rinse wound surface foreign body chip.This corneal foreign matter removing device of prior art is mainly to utilize hollow needle body to choose, scrape multiple operation to foreign body, in actual mechanical process, be easy to damage cornea, and pick the foreign body of choosing and be easy to drop down onto patient's eyeball surface, also need to adopt tweezers or other aid by foreign body folder from eyeball.
Summary of the invention
The purpose of this utility model is to provide a kind of and in operating process, is not easy to damage patient's cornea and does not need to adopt aid that foreign body is pressed from both sides to the corneal foreign matter removing device from patient's eyeball surface.
This utility model adopts following technical scheme: a kind of corneal foreign matter removing device, it comprises that piston cylinder and one end are arranged on the piston rod in piston cylinder, on piston cylinder, be fixed with the suction pipe being communicated with cavity in piston cylinder, piston rod is positioned on one end of piston cylinder and is fixed with magnetic tip.
The end of described suction pipe has the inclined-plane of 15 °.
Described suction pipe is made by magnetic conductive material.
This utility model utilizes magnetic tip on piston rod by the magnetic conductive metal foreign body sucking-off in patient's cornea, and foreign body is entered in piston cylinder by suction pipe under magneticaction, thereby makes foreign body depart from patient's eyeball surface; When the foreign body in patient's cornea does not have magnetic conductivity, can use suction pipe that foreign body is chosen, the piston cylinder of then holding with a firm grip on the other hand, another pulls moving piston rod foreign body is drawn in piston cylinder by suction pipe.This utility model can disposablely complete foreign body eliminating and depart from the work of eyeball, does not need to use in addition aid again, but also is not easy to damage cornea, is particularly useful for rejecting magnetic foreign body.This utility model is simple in structure, and cost is low, workable.
Further, suction pipe end has the inclined-plane of 15 °, be conducive to suction pipe will be not the magnetic foreign body of tool choose.
Further, the suction pipe that magnetic conductive material is made can make magnetic foreign body very easily by suction pipe, be entered in piston cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is elaborated.
The structure of a kind of embodiment of this utility model as shown in Figure 1, the corneal foreign matter removing device of the present embodiment comprises that piston cylinder 1 and one end are arranged on the piston rod 2 in piston cylinder, piston rod 2 extend into and on the one end in piston cylinder 1, is fixed with piston 3, the other end of piston rod 1 is fixedly connected with handle, the present embodiment is fixed with magnetic tip 4 on the surface of piston 3, on piston cylinder 1 over against being fixed with the suction pipe 5 being communicated with cavity in piston cylinder on the position of piston 3, this suction pipe 5 adopts magnetic conductive material to make, and the end of suction pipe 5 has the inclined-plane of 15 °.
When the foreign body in patient's cornea has magnetic conductivity, suction pipe 5 is aimed to foreign body, utilize magnetic tip 4 on piston rod by the magnetic conductive metal foreign body sucking-off in patient's cornea, foreign body is entered in piston cylinder 1 by suction pipe 5 under magneticaction, thereby makes foreign body depart from patient's eyeball surface; When the foreign body in patient's cornea does not have magnetic conductivity, can use suction pipe end that foreign body is chosen, 15 ° of inclined-planes of suction pipe end are conducive to choose smoothly foreign body, and the piston cylinder 1 of then holding with a firm grip on the other hand, another pulls moving piston rod 2 foreign body is drawn in piston cylinder 1 by suction pipe.The present embodiment can disposablely complete foreign body eliminating and depart from the work of eyeball, does not need to use in addition aid again, but also is not easy to damage cornea, is particularly useful for rejecting magnetic foreign body.The present embodiment is simple in structure, and cost is low, workable.
Above-described embodiment is a kind of preferred embodiment of this utility model, and in other embodiment of the present utility model, the magnetic tip of piston rod end also can be arranged on the inside of piston.
In other embodiment of the present utility model, suction pipe also can adopt non-magnetic material to make, and the metal materials such as nonmetallic materials such as plastics, resin or copper, aluminum are made.
In other embodiment of the present utility model, the bevel angle of the end of suction pipe can be between 10 ° ~ 60 °.
