Abstract
The utility model relates to an eyelid expander, belonging to the technical field of a medical appliance. The eyelid expander comprises a main beam (1), an upper stretch arm (2), a lower stretch arm (3), a screw rod (4), a limit block (5) and eyelid supports (7), wherein the upper stretch arm (2) and the lower stretch arm (3) are arranged to be arc shapes and are respectively articulated at two ends of the main beam (1); the screw rod (4) is connected with the limit block (5) by thread; the limit block (5) is articulated with the upper stretch arm (2); a sleeve ring (6) is arranged at the lower end of the screw rod (4); the sleeve ring (6) is articulated with the lower stretch arm (3); and the eyelid supports (7) are arranged at the end parts of the upper stretch arm (2) and the lower stretch arm (3). The eyelid expander realizes the actions of expanding and contracting the eyelid supports under the combined action of the screw rod, the stretch arms and the limit block, is adjusted by thread so as to be more accurate in operation, and is safe, and the medical treatment effect is improved.
Description
Technical field
This utility model relates to technical field of medical instruments, is specially a kind of eye-speculum.
Background technology
Eyelid is commonly called as eyelid, is positioned at eyeball the place ahead, constitutes the barrier of protection eyeball, and eyelid can be protected the most vulnerable cornea of eyeball and its underpart, and has the effect that tear is spread to whole eye mask and cornea.During general operation aspect doing eyeball, because the physiological reaction of closing one's eyes of human body itself, usually need strut eyelid to expose eyeball by mechanical means and be convenient to the carrying out of performing the operation, the apparatus structure of prior art is single, what have must or manually fix by other apparatuses, makes it to exist in operation process certain danger, may damage eyeball, strut distance and be difficult to control and adjusting, this brings very big obstacle to operation.
Summary of the invention
In order to solve the deficiencies in the prior art, this utility model provides a kind of eye-speculum that can accurately regulate the folding degree.
The technical solution of the utility model is: a kind of eye-speculum, comprise girder, on strut arm, strut arm, screw rod, position-limiting tube and eyelid holder down, position-limiting tube is arranged in the mesopore that struts arm, and with on to strut arm hinged, on strut arm and strut down the two ends that arm is set to arc and is hinged on girder respectively, screw rod is threaded with position-limiting tube, position-limiting tube and on to strut arm hinged, the screw rod lower end is provided with the collar, the screw rod bottom is connected in the collar, the collar is with to strut down arm hinged, on the end that struts arm and time strut arm be provided with the eyelid holder.
Described eyelid holder is an arc.
Described eyelid holder is outside equipped with one deck soft gum cover.
Described eyelid holder cross section is " U " type.
Work process of the present utility model is: by the rotary screw end, screw rod rotates in position-limiting tube, and position-limiting tube moves up and down, and then drives and to strut arm and to strut arm realization opening and closing movement down, and last palpebra inferior is in the support of the eyelid holder folding of leaving behind.
The beneficial effect of this eye-speculum is: screw flight connects, and the expansion of dilator is more accurate with the gathering action, and this arcuate structure mode is compact simple, and it is little to take up room, and handled easily effectively raises the subsequent procedures operating efficiency.
Description of drawings
Accompanying drawing is this utility model overall structure sketch map.
The specific embodiment
A kind of as shown in drawings eye-speculum, comprise girder 1, on strut arm 2, strut arm 3, screw rod 4, position-limiting tube 5 and eyelid holder 7 down, position-limiting tube 5 is arranged in the mesopore that struts arm 2, and with on to strut arm 2 hinged, on strut arm 2 and strut the two ends that arm 3 is set to arc and is hinged on girder 1 respectively down, screw rod 4 is threaded with position-limiting tube 5, position-limiting tube 5 with on to strut arm 2 hinged, screw rod 4 lower ends are provided with the collar 6, screw rod 4 bottoms are connected in the collar 6, the collar 6 is with to strut arm 3 down hinged, on the end that struts arm 2 and time strut arm 3 be provided with eyelid holder 7.
Described eyelid holder 7 is arcs, meets the radian of a frame, avoids eye socket is caused the compressing damage.
Described eyelid holder 7 is outside equipped with one deck soft gum cover, avoids dilator that eyelid etc. is damaged.
Described eyelid holder 7 cross sections are " U " type, ensure the stability after the eye-speculum expansion, and that guarantees to perform the operation carries out smoothly.
Operator are by by rotary screw 4 ends, and screw rod 4 rotates position-limiting tube 5 in, and position-limiting tube 5 moves on screw rod, so strut on driving arm with under strut arm realization opening and closing movement, last palpebra inferior is in the support of the eyelid holder folding of leaving behind.
Claims (4)
1. eye-speculum, it is characterized in that: comprise girder (1), on strut arm (2), under strut arm (3), screw rod (4), position-limiting tube (5) and eyelid holder (7), on strut arm (2) and strut down the two ends that arm (3) is set to arc and is hinged on girder (1) respectively, screw rod (4) is threaded with position-limiting tube (5), position-limiting tube (5) is arranged in the mesopore that struts arm (2), and with on to strut arm (2) hinged, screw rod (4) lower end is provided with the collar (6), screw rod (4) bottom and the collar (6) clamping, the collar (6) is with to strut down arm (3) hinged, on the end that struts arm (2) and time strut arm (3) be provided with eyelid holder (7).
