Existing corneal trephine is fairly simple, is usually made of body portion and knife portion.Cornea has certain toughness, uses traditional cornea
When trepan is cut, it is often necessary to which firmly pushing repeated multiple times rotation corneal trephine could succeed, and operation is time-consuming and laborious, and cuts
The edge of cornea serious wear taken, to influence to heal.
Invention content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of simple in structure, design conjunction is provided
Reason, clamp type corneal trephine easy to use.
To achieve the above object, the technical solution adopted in the utility model is：It includes scissor handle, cutter head, cutter head
Pedestal；The scissor handle includes upper handle, lower handle；The infall of upper handle and lower handle is connected by axis pin；On
The end of handle and lower handle is equipped with the strip handle being mutually parallel；The bottom surface of strip handle on lower handle is horizontal puts down
Face；It is connected with spring between two strip handles；The front end of lower handle supports for Y shape；The front end of Y shape support and cutter head grafting
Connection；The front end of upper handle is fixedly connected with cutter head pedestal；Cutter head pedestal is located at the underface of cutter head；The bottom surface of cutter head pedestal
It is smooth, and point-blank with the bottom surface of strip handle on lower handle, constitute a stable plane；Cutter head pedestal it is upper
Portion is padded equipped with arc；
Preferably, the cutter head uses frustum of a cone cutter head, and the bottom of cutter head is circular blade；
Preferably, the front end of the described Y shape support sets that there are two symmetrical slots；The upper end both sides of cutter head are equipped with
Two symmetrical supporting rods；The end of supporting rod is plugged in the slot of Y shape support；
Preferably, the upper surface of the cutter head pedestal is equipped with arc convex；Arc liner is placed on arc convex.
With the above structure, the utility model has the beneficial effect that：A kind of clamp type corneal ring described in the utility model
It bores, operation is time saving and energy saving, and cornea waste is few, and cornea incisxal edge is more neat, and it is irregular and influence wound to be not susceptible to cornea incisxal edge
The problem of healing, and have many advantages, such as that simple in structure, setting is reasonable, low manufacture cost.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the vertical view of cutter head.
Reference sign：
1, cutter head pedestal；2, arc convex；3, arc pads；4, cutter head；5, Y shape supports；6, axis pin；7, upper handle；8,
Spring；9, strip handle；10, lower handle；11, supporting rod.
Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is further described.
Shown in Fig. 1-2, present embodiment the technical solution adopted is that：It include scissor handle, cutter head 4,
Cutter head pedestal 1；The scissor handle includes upper handle 7, lower handle 10；Upper handle 7 and the infall of lower handle 10 pass through
Axis pin 6 connects, and forms laborsaving lever structure；Upper handle 7 and the end of lower handle 10 are equipped with the strip handle 9 being mutually parallel；Under
The bottom surface of strip handle 9 on handle is horizontal plane；Spring 8 is connected between two strip handles 9, spring 8 makes knife
Head pedestal 1 is held apart at cutter head 4, conducive to object to be cut is placed on cutter head pedestal 1；The front end of lower handle 10 supports for Y shape
5；The front end of Y shape support 5 and 4 plug connection of cutter head；The front end of upper handle 7 is fixedly connected with cutter head pedestal 1；Cutter head pedestal 1
It is located at the underface of cutter head 4；The bottom surface of cutter head pedestal 1 is smooth, and straight at one with the bottom surface of strip handle 9 on lower handle
On line, a stable plane is constituted, in use, being not necessarily to assistant's fixed caliper；The top of cutter head pedestal 1 is equipped with arc and pads 3,
Cornea is set more to be bonded, replaceable after 3 abrasion of arc liner, arc 3 quality of liner are tough, are conducive to cut and are not easy to wear cornea；
The cutter head 4 uses frustum of a cone cutter head, and the cornea after cutting is made easily to take out, and the bottom of cutter head 4 is sharp
