Abstract
The utility model relates to an ophthalmic surgical instrument, in particular to an interlamellar dissection surgical instrument for a cornea laser operation. The interlamellar dissection surgical instrument for the cornea laser operation comprises a handle, a front separating rod and a rear separating rod, wherein the front separating rod and the rear separating rod are fixedly connected with two ends of the handle. A bent section with an inclined angle of 120 degrees-150 degrees is arranged in the middle of the front separating rod, and a bent section with an inclined angle of 120 degrees -150 degrees is arranged in the middle of the rear separating rod. An oval flat hook body is arranged at the top end of the front separating rod. The central axis of the hook body is an arc line. A diamond flat cutter body is arranged at the top end of the rear separating rod. The central axis of the cutter body coincides with the central axis of the rear separating rod. A flat structure is adopted by the end portion of the front separating rod, and a flat structure is adopted by the end portion of the rear separating rod, and therefore use is convenient, and the interlamellar dissection effect of the cornea is good. The bent section of the front separating rod and the bent section in the middle of the rear separating rod accord with human engineering principles, and are applicable to handheld operation.
Description
Technical field
This utility model relates to a kind of ophthalmic operating set, is a kind of interlaminar separation operating theater instruments for the cornea laser operation specifically.
Background technology
Full femtosecond laser operation is the bathomorphic ophthalmologic operation for the treatment of of commonly using.In operation, the separation of eyes inter-lamination of cornea has material impact to the operation quality.Existing interlaminar separation operation tool is all simple detaching hook, and the coupler body tip is cylinder or coniform, and the top is blunt rounded.The instrument of this blunt rounded and the contact surface of cornea are less, easily tear or break cornea, cause operative failure.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to use, interlaminar separation is effective is used for the interlaminar separation operating theater instruments of cornea laser operation.
Interlaminar separation operating theater instruments for the cornea laser operation described in the utility model comprises handle, is fixedly connected on front declutcher control lever and the rear declutcher control lever at handle two ends, the middle part of described front declutcher control lever and rear declutcher control lever is all with 120 °---the bending section of 150 ° of angles, it is characterized in that: on the top of front declutcher control lever with the coupler body of oval flat, the axis of described coupler body is camber line, with the cutter hub of prismatic flat, the axis of described cutter hub overlaps with the axis of rear declutcher control lever on the top of rear declutcher control lever.
After adopting said structure, flat structure is all adopted in the end of front declutcher control lever and rear declutcher control lever, is convenient to entering angle membrane tissue interlayer, and is large with the contact area of cornea, can avoid tearing or breaking cornea; Flat structure has " side edge " of appropriateness, has " cutting " to act on to tissue, particularly to not by the tissue of the abundant cutting section of laser (as OBL, namely due to opaque bubble layer), the passivity apparatus is undivided, and this apparatus can easily be separated; The passivity apparatus is that inter-lamination of cornea tissue " tearing " is opened, so can be heavier to tissue injury and reaction; And this apparatus is that inter-lamination of cornea tissue " cutting " is opened, so to tissue injury and react low weight; Because the apparatus core head after improving is flat, so enter inter-lamination of cornea in performing the operation after, avoided the passivity apparatus swollen to the support of " cap ".The bending section at the middle part of front declutcher control lever and rear declutcher control lever meets principle of human engineering, is fit to hand-held.

Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the A section partial enlarged drawing of Fig. 1 embodiment.
Fig. 3 is the B section partial enlarged drawing of Fig. 1 embodiment.
The specific embodiment
as shown in Figure 1, interlaminar separation operating theater instruments for the cornea laser operation described in the utility model comprises handle 1, be fixedly connected on front declutcher control lever 2 and the rear declutcher control lever 3 at handle 1 two ends, the middle part of described front declutcher control lever 2 and rear declutcher control lever 3 is all with 120 °---the bending section of 130 ° of angles, on the top of front declutcher control lever 2 with the coupler body 4 of oval flat, the axis of described coupler body 4 is camber line, on the top of rear declutcher control lever 3 with the cutter hub 5 of prismatic flat, the axis of described cutter hub 5 overlaps with the axis of rear declutcher control lever 3, the marginal portion of cutter hub 5 is with knuckle.
During use, according to different situations, can choice for use before coupler body 4 on declutcher control lever 2 or the cutter hub 5 on rear declutcher control lever 3, hook cornea tissue or insert the cornea tissue interlayer, be isolated.
