Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an instrument for medical treatment such as inverted eyelashes.

(Prior Art) Conventionally, the ophthalmic forceps of this type of instrument are as shown in Fig. 5.
As shown in FIG. 6, it has a structure in which the clamping surfaces 13 of both thin rod-shaped knobs 12 extending at the tip of the bifurcated gripping part 11 face each other in a parallel state, and the eyelashes A are clamped. When putting on the eyelashes, the clamping surfaces 13 of the knobs 12 moved parallel to each other to the center, and clamped the eyelashes A from both sides in parallel.

(Problems to be Solved by the Invention) However, in the conventional structure described above, when the eyelashes A are pinched, the pinching surfaces 13 are pinched in parallel from both sides of the eyelashes A as shown in FIG. Therefore, the eyelashes A are directly subjected to the strong clamping force that tries to close the knob part 12, and the eyelashes A have a drawback that they are often cut.

Therefore, this idea was developed in view of the above-mentioned drawbacks of the conventional technology.
To solve this problem, and to obtain an inexpensive tool for treating eyelashes, etc., which can reliably clamp the eyelashes without cutting them without applying the closing force of the knob directly when clamping the eyelashes. It is in.

(Means for Solving the Problem) As a means to achieve this, this invention has two narrow rod-shaped knobs at the tip of the bifurcated elastic grip so that the clamping surfaces face each other at an angle. At the same time as opening, one end of the short gap between the two clamping surfaces comes into contact with each other due to the clamping operation, and both clamping surfaces rotate using the end as a fulcrum to clamp the object to be clamped. This is what I did.

(Example) An example of a specific configuration of this invention shown in the drawings will be described in detail below.

1 to 3 show a first embodiment of this invention, in which a forceps 1, which is an instrument for ophthalmic treatment, has a bifurcated elastic gripping part 3 with a base 2 connected and fixed. The tip side of the knob is bent and extended so as to have a step downward, and is shaped like a narrow rod, forming knob parts 4, 4, respectively, and a clamping part on the inner side facing the tip of the knob part 4. The surfaces 5 are each inclined toward each other from the upper end to the lower end. That is, the interval dimension a between the upper ends of both clamping surfaces 5 is formed to be larger than the interval dimension b between the lower ends.

With this structure, in order to pull out the inverted eyelashes A with this forceps 1, hold the grip part 3 and insert the inverted eyelashes A between the knob parts 4 and 4 whose tips are opened. After positioning as shown in Figure 2A and Figure 3A, the gripping part 3 is squeezed from both sides against its elasticity,
When the knobs 4, 4 at the tips are moved in the closing direction,
Since the clamping surfaces 5 of the knob portion 4 face each other in an inclined manner, the lower end 5 with a small interval between the clamping surfaces 5, 5
a and 5a contact each other as shown in FIG. 2B and FIG. The upper end portions 5b rotate to approach each other and pinch the reversed eyelashes A, and as shown in FIG. 2C and FIG. be sure to clamp it.

FIG. 4 shows a second embodiment of this invention, in which the clamping surfaces 5 of the knob portion 4 are formed to be inclined to each other as in the first embodiment. It protrudes in an arc shape to form a flat part 6 for danger prevention.

As a result, when the tip of the forceps 1 is brought close to the eye to pinch the inverted eyelashes A, even if the clamping surface 5 accidentally comes into contact with the eye, there is no risk of the eye being pierced by the flat part 6. This prevents the inverted eyelashes A from being caught.

Although the above-mentioned embodiment is an example in which the present invention is applied to ophthalmological forceps, the present invention is not limited thereto, and may be used in a medical treatment instrument that clamps a thin wire-shaped body that is easy to cut.

(Effects of the invention) As described above in detail with respect to the various embodiments, in this invention, the clamping surfaces at the tips of the gripping parts are inclined and face each other, so when clamping eyelashes, etc., After one end of the clamping surface makes contact and once receives the clamping force of the gripping part, the clamping surface rotates using the contacting end as a fulcrum to softly clamp the eyelashes, etc., thereby cutting the eyelashes. It can be clamped securely without any problems. Moreover, it has a simple structure, is easy to manufacture, and has the excellent effect of providing a robust and inexpensive product.
