先端部の折曲げ加工方法について種々研究を重ねた結果
本発明に到達した。BACKGROUND ART In the conventional ophthalmology, when a lens is removed for surgery for a disease of the lens of the eye, the anterior capsule of the lens is cut into small pieces. At that time, the operation is performed by using an injection needle whose tip portion is bent into a shape suitable for incision, and each time the injection needle is processed, the operator uses an arbitrary instrument method. This process requires skill,
There were drawbacks such that it was easy to use and it was difficult to form a uniform shape. The present inventors have arrived at the present invention as a result of various studies on a method of bending the tip portion of the injection needle used for the above treatment.

In the processing device, the tip processed portion of the injection needle to be processed is inserted into a gap portion of a predetermined portion that substantially matches the size of the processed portion,
The base of the injection needle is lifted up and bent, so bending work can be done very easily and easily without the need for skill, and the shape of the obtained incision knife does not change with each operation, and the incision always has the same shape. A surgical sword can be easily obtained by forming a sword.

固定している。The gap (3) between the contact surfaces of the base (1) and the support piece (2) is
The needle-shaped material (10) such as an injection needle to be processed is formed so that it can be inserted according to the size, size, etc. of the processed end portion. That is, the gap (3) is a needle-shaped material (10) for injection or the like to be processed, which has two or more different sizes and dimensions of the tip processing part or the like.
So that the gap can be inserted in response to the direction from the one side end corresponding to the direction orthogonal to the inserting direction of the needle-shaped material such as the injection needle to be processed toward the other side end. After being formed (see FIG. 3), two or many needle-shaped materials to be processed having different sizes of the processing tip can be processed by one device. (4) and (4 ') are separable pieces having different heights, which are arranged at both left and right end portions between the base (1) and the support piece (2).
The contact surface (1a) facing (2) and the gap portion (3) between (2a) are formed so as to be narrowed to one side as described above, and the base (1) is provided via the screw (5), The partition pieces (4), (4 ') and the support piece (2) are integrally fixed.

It is possible to prevent deformation due to defects and the like. In the illustrated example, small pieces (6) and (7) of special steel are fitted to a stainless steel base and a support piece to form a contact surface. In addition, the base or support piece is displayed with the size and other information that is a guide for the size of the gap (8)
Is provided. Further, a notch (9) is formed in the rear part of the base so that the notch (10c) does not come into contact with the base surface when the tip of the needle-shaped material to be processed is inserted into the gap. ,
The sharpness of the tip is retained.

もし易くなる。With the above processing device, for example, 25G × 1 ″ (0.50 × 2
When a 5 mm) injection needle (10) is processed to form a surgical sword, the injection needle is placed in a gap corresponding to the processed portion depending on the size of the processed portion at the tip. Insert the required length by making the opening surface of the needle hole the contact surface (1a) side of the base and at a substantially right angle to the opening surface of the gap, and support the base portion (10b) of the injection needle with the fingertips upwards, When the needle is lifted up to an appropriate position, the processing portion at the tip of the injection needle can be bent at a desired bending angle with the contact surface of the inserted gap as a fulcrum. In this case, the needle-shaped material is inserted into and supported by the gap corresponding to the size, so that even if the same injection needle is processed, an incision knife of almost the same shape is required each time the processing is performed, and it is extremely easy without requiring skill as in the past. It can be obtained easily, and the operation becomes easy.
