It is to play a part of supporting eyelid similar to drag hook in surgical operation.It is usually to be completed with steel wire eye speculum in the prior art, this
Kind eye speculum, which often exists, to be not easy to grasp, and causes stability bad, while medical personnel be present and strutting eyelid with eye speculum
When, it is not easy to the width that accurate control eyelid is opened, easily causing operation can not be smoothed out.In addition, eye speculum is also deposited at present
Bad technical problem is being bonded with eye.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided a kind of rotatable eye speculum, solve out
The bad technical problem of eyelid device stability, solve eye speculum and strut the technical problem that precision can not be controlled accurately, solve eye speculum
Bad technical problem is bonded with eye, using the eye speculum, the accurate control of medical personnel can be easy to, while branch can also be passed through
The rotation realization of support part is engaged with eyes, ensures that the scope of application of eye speculum is wider.
The technical solution adopted by the present invention is as follows：The present invention uses a kind of rotatable eye speculum, including two dilators, institute
State two dilators and be respectively equipped with and strut bar and strut handle, two dilators are to make its company strutting bar and strut handle connecting place with bearing pin
Connect, and formed and be rotatablely connected with bearing pin, described two, which strut bar front end, is connected with supporting part, and the supporting part connects with strutting bar and rotating
Connect, the abutment surfaces are provided with shoe.
Further, the bearing pin is also connected with a fixing device, and described fixing device one end is connected with bearing pin, and fixing device is another
One end is connected with elastic device, is connected with pushing block below elastic device, the pushing block both sides, which are respectively articulated with, is connected with two pull bars, described
The two pull bar other ends strut handle with two respectively and are hinged.
Because using said structure, by pushing block compression spring, and then pushing block travels forward, and drives two pull bars fortune
Dynamic, two pull bars drive two dilators to be rotated around bearing pin, and then realize the folding of two supporting parts.The design fitting eyelid of supporting part,
Groove ensures that strutting portion will not damage to eye with strutting tooth surface arc-shaped transition.Supporting part is rotatablely connected with strutting bar,
It can realize that supporting part is bonded with the optimal of eye by rotating, the setting of shoe further ensures eye speculum and eye
Fitting, so as to ensure support zone in the stability of eye.
Further, the fixing device is located at bearing pin bottom and fixing device is strutted between handle positioned at two.
Further, screw mandrel is fixedly connected with rear side of the pushing block, the screw mandrel is provided with the nut matched with screw mandrel, leads to
Cross rotation of the nut on screw mandrel and realize that nut drives pushing block motion.
Due to that using said structure, can be push by operating nut when the motion on screw mandrel is and then nut forward
Motion block travels forward.
Further, the supporting part struts tooth and groove including two, and described two strut tooth is located at supporting part both ends, institute respectively
State groove to be located in the middle part of supporting part, the groove is connected with strutting tooth surface arc, described to strut tooth and groove is located at dilator
Outside.
Further, the elastic device is spring.
Further, the shoe is fin, and the fin is made up of medical plastic.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：One kind of the present invention is rotatable
Eye speculum, pushing block is exerted oneself by nut, pushing block compression spring, and then realize that pushing block travels forward, so as to control
The folding of dilator, can reach the angle of accurate control dilator folding, and the setting of spring can play certain buffering and damping
Effect, ensure stability during regulation, minor adjustment and then the accurate folding for controlling dilator by operating nut, significantly
The stability that eye speculum uses is improved, supporting part is bonded with strutting the achievable supporting part of bar rotation connection with the optimal of eye,
The setting of shoe further ensures being bonded for eye speculum and eye, so as to ensure support zone in the stability of eye,
And then it ensure that being smoothed out for operated eye.
