Description
Technical field
The present invention relates to medical instrument, especially a kind of special eye speculum of eye.
Background technology
With the development of society, electronic product is increasingly popularized, people also become increasingly dependent on electronic product, cause eye
The incidence of disease is also higher and higher, and in operated eye treatment, eye speculum is essential, the operation principle of eye speculum
It is to play the role 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 of eye speculum, which often exists, to be not easy to grasp, and causes stability bad, while there are medical staff to strut eyelid with eye speculum
When, it is not easy to the width that accurate control eyelid is opened, be easy to causeing operation cannot be smoothed out.
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 special eye speculum of eye,
The bad technical problem of eye speculum stability is solved, eye speculum is solved and struts the technical problem that precision cannot be controlled accurately,
Using the eye speculum, it can accurately be controlled easy to medical staff, ensure being smoothed out for operated eye.
The technical solution adopted by the present invention is as follows：The present invention uses a kind of special eye speculum of eye, 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 axis pin
Connecing, and formed and be rotatablely connected with axis pin, the axis pin is also connected with a fixing device, and described fixing device one end is connected with axis pin,
The fixing device other end is connected with elastic device, is connected with pushing block below elastic device, the pushing block both sides are connected with two drawings respectively
Bar, the two pull rods other end strut handle with two respectively and are hinged.
Further, described two strut bar front end and be connected with supporting part, the supporting part is fixedly connected with strutting bar.
Due to using the above structure, compressing spring by pushing block, and then pushing block travels forward, and drives two pull rods fortune
Dynamic, two pull rods drive two dilators to be rotated around axis pin, and then realize the folding of two supporting parts.The design fitting eyelid of supporting part,
Groove ensures that eye will not be damaged by strutting portion with strutting tooth surface arc-shaped transition.
Further, the fixing device is located at axis pin lower part and fixing device is strutted between handle positioned at two.
Further, be fixedly connected with screw on rear side of the pushing block, the screw be equipped with the matched nut of screw, lead to
Cross rotation of the nut on screw and realize that nut drives pushing block movement.
Due to that using the above structure, can be push by operating nut when the movement on screw 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.
Further, the elastic device is spring.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：A kind of eye of the present invention is special
With eye speculum, exerted oneself by nut to pushing block, 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, stability when ensureing to adjust, minor adjustment and then the accurate folding for controlling dilator by operating nut, significantly
The stability that eye speculum uses is improved, and then ensure that being smoothed out for operated eye.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the structure diagram of eye speculum；
Fig. 2 is fixing device cross-sectional view.
Marked in figure：1 for strut bar, 2 for strut handle, 3 be axis pin, 4 be supporting part, 5 be fixing device, 6 be elastic dress
Put, 7 be pushing block, 8 be pull rod, 9 be screw, 10 be nut, 11 to strut tooth, 12 be groove.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary）Disclosed in any feature, unless specifically stated,
Replaced by other equivalent or with similar purpose alternative features.I.e., unless specifically stated, each feature is a series of
An example in equivalent or similar characteristics.
As shown in Fig. 1-2, the special eye speculum of a kind of eye of the invention, including two dilators, the two dilators difference
Equipped with strutting bar 1 and strut handle 2, two dilators are to make its connection strutting bar 1 and strut 2 connecting place of handle with axis pin 3, and with pin
Axis 3 forms rotation connection, and the axis pin 3 is also connected with a fixing device 5, and described 5 one end of fixing device is connected with axis pin 3, fixed
5 other end of device is connected with elastic device 6, and the lower section of elastic device 6 is connected with pushing block 7, and 7 both sides of pushing block are connected with two drawings respectively
Bar 8, it is hinged that two pull rods, 8 other end struts handle 2 with two respectively.Further, described two strut 1 front end of bar and be connected with supporting part 4,
The supporting part 4 is fixedly connected with strutting bar 1.The fixing device 5 is located at 3 lower part of axis pin and fixing device 5 is strutted positioned at two
