A fissuriform blade flute is arranged at the front end of the handle, and included angle between a handle axis and the blade flute is in 135 DEG; a front end face of the handle is an inclined plane which is parallel to the blade flute; the inner core is positioned in a cavity of the handle, and the back end of the handle is combined with screw threads of the handle; the front end of the handle is tightly supported on the blade. The handle of the utility model has the advantages that razor blades with low price can be used for operations, the included angle between the blade which is clamped and the handle axis is in 135 DEG, consistent direction of the blade and the incisions can be realized in a favorable field of view, and a cataract operation for small incisions is completed.

Description

The special-purpose handle of a knife of the little otch of ophthalmologic operation

This utility model belongs to medical surgical instrument, mainly proposes the special-purpose handle of a knife of the little otch of a kind of ophthalmologic operation, is mainly used in Small-incision cataract extraction.

In Small-incision cataract extraction, (comprise emulsifying of far sound and the non-phacoemulsification cataract extraction art of little otch), when making little otch, what adopt all is disposable import cataract operation cutter, have cost an arm and a leg, shortcoming that access times are few, be the consumable goods of operation.Be used for clinical knife blade clamper now, can utilize cheap razor blade to do otch, but because the direction of blade of being held and clamper is consistent, the tunnel incision direction of little otch requires to be basically level, and blade drive rotaining device can not be put into horizontal direction fully because there is patient's eyelid to stop and operates, and then cause tunnel incision imperfect, do not reach the requirement of little otch.

The purpose of this utility model is to propose the special-purpose handle of a knife of the little otch of a kind of ophthalmologic operation, overcomes the defective that exists on the existing operation sheet clamper structure.

This utility model is finished the technical pattern that its invention task takes: it mainly comprises the handle of setting blade and in order to tighten up the inner core of blade; The handle front end have with the handle of a knife axis be 135 ° of angles, in order to embed the cutter groove of knife blade, the handle front end face is the inclined-plane parallel with the cutter groove.Inner core is positioned at handle cavity, and its rear end combines with the handle screw thread, and front end is positioned at the blade that the handle front end holds out against the cutter groove.

Manipulating of this utility model handle of a knife.

1, the relative handle of inner core is unscrewed, the razor blade of breaking off with the fingers and thumb is put into the seam shape cutter groove of handle front end, screw inner core blade is held out against.

2, using the blade distance corneoscleral junction 2mm that is 135 ° of angles with handle axis to be anti-geisoma shape flaggy cuts.

3, with the parallel puncture forward of blade, enter in the transparency cornea behind the 1mm, oblique anterior chamber penetrates cornea with blade, finishes otch.

The handle that the utility model proposes can use cheap razor blade to undergo surgery, and the blade of clamping and handle axis are 135 ° of angles, can accomplish in the good visual field that blade is consistent with cut-out direction, finishes small incision cataract surgery.It is simple and reasonable, operation is comparatively simple.

Embodiment:

Accompanying drawing 1 is this utility model structural representation.

The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:

Shown in accompanying drawing 1,2, this utility model handle of a knife comprises the handle 3 and the inner core 2 in order to tighten up blade of setting blade 1; Handle 3 adopts rustless steel to make, and its front end has set seam shape cutter groove, and cutter groove and handle axis are 135 ° of angles, and the front end face of handle is the inclined-plane parallel with the cutter groove.Inner core 2 is positioned at the cavity of handle, and its rear end external screw thread combines with the female thread of handle, and the blade 1 that its front end will embed the cutter groove holds out against.Be similar to the structure of the ball pen inner core and the pen cap.
