最も好結果に利用できるものである。DETAILED DESCRIPTION OF THE INVENTION This invention relates generally to medical instruments, and more particularly to instruments for measuring the depth of a clean incision during eye surgery. That is, the present invention can be used with the best results in surgical treatment of myopia.

野の特殊な条件のため、眼科手術に採用すること
ができない。 Currently, there are no special instruments that measure the depth of incisions made during eye surgery. Therefore, the surgeon must use his thumb as a ruler to measure the approximate depth of the incision. Of course,
This method does not allow us to know the exact depth required for the incision. However, even slight unevenness in the depth of the incision can significantly affect the characteristics and results of the patient undergoing surgery, and can cause, for example, astigmatism. However, depth measuring instruments and devices used in other engineering fields cannot be adopted in ophthalmic surgery due to the special conditions of this medical field.
本発明の目的は手術中に切開の深さを精密正確

り、この測定はリミツトゲージに基づいている。 An object of the present invention is to provide an instrument for measuring the depth of a non-perforating incision in ophthalmic surgery, which is capable of precisely and accurately measuring the depth of an incision during surgery, and this measurement is based on a limit gauge. .
この目的は次の本発明の構成により達成され

る。 This object is achieved by the following configuration of the present invention. That is, an instrument for measuring the depth of an incision in ophthalmic surgery, the handle of which includes a V-shaped member, one leg of which is rigidly attached to the handle, the other leg being fixed to the axis of the handle. and the free end of this leg is located on the axis, and the protrusion is located at an appropriate distance from the edge of the free end of the other leg, and This protrusion is placed across the leg.

に目盛りを追加することは好都合である。 A feature of the device proposed here is that the limiting section between the free end of the leg and the projection is actually a limit gate. As generally understood, limit gauges provide precise measurements within set limits. In order to increase the accuracy of the measurements, it is advantageous to add a graduation on the leg itself over the width of the leg in the area of the front and rear ends of the projection.
また、眼球を容易に切開できるように、突出部

ある。 The medical instrument of the present invention for measuring the depth of a non-perforating incision in an eyeball in ophthalmic surgery is provided with a straight handle 1 having a knurled portion 2 for ease of grip by the surgeon. Further, the V-shaped member 3 is made of stainless steel, for example, one leg 4 of this member 3 is connected to the handle 1, and the angle β between the leg 4 and the other leg 5 is , such that the free end of the leg 5 is on the axis OO of the handle 1, and the leg 5 itself is approximately 10
Forming an angle of ~75°. In terms of ease of use for the surgeon, the best results are obtained with an angle β of about 10° to about 40°. A projection 6 is provided on the leg 5 itself near the free end of the leg 5, across its width and at a suitable distance from the edge of said free end.
is not shown in FIG. 1 because it is too small. For ease of understanding, the protrusion 6 is shown in FIG. 2, in which the leg 5 is enlarged (50:1).

器具のハンドルに刻み込んで記してある。 As can best be seen in FIG. 2, the projection 6 is provided across the leg 5, with the surface 7 of the leg 5 being located at a suitable distance from the free end of the leg 5. The length of this distance is etched into the handle of the instrument for the convenience of the surgeon.
第３図から明らかなように、脚５の終端部は薄
くなつており、ゲージマーク８，９は突出部６の
両端縁において脚５を横切つて設けてある。 As is clear from FIG. 3, the ends of the legs 5 are tapered and the gauge marks 8, 9 are provided across the legs 5 at both end edges of the projections 6.
ゲージマーク８および９の間の距離は正確な測
定値を得るため厳守なものである。 The distance between gauge marks 8 and 9 must be strictly adhered to in order to obtain accurate measurements.

様な器具によつて切り込みの深さを測定する。 The inventive instrument for measuring the depth of a non-perforating incision can be used in the most important stages of ophthalmic surgery, such as surgical correction of myopia, laminated keratoplasty, retinal detachment (uniform incision of the sclera), and surgical treatment of intramarginal defects. It is used in After making a radial incision in the cornea (for surgical correction of myopia) or a uniform incision in the sclera (for retinal detachment surgery), the surgeon measures the depth of the incision (Figure 4). To this end, the surgeon grasps the handle 1 of the instrument, inserts the instrument into the incision, holds the leg 5 against the bottom of the surgical incision groove, and measures the depth of the incision by the position of the measuring protrusion 6. If the depth of the incision does not reach the required value, the surgeon makes a more uniform incision to the required depth and then measures the depth of the incision with a separate similar instrument.
