Then, the suture thread a of a predetermined length can be freely removed and inserted into the hollow hole 1a of the tubular needle 1 through the guide hole 2a while the tubular needle 1 is pierced between the both sides of the wound site.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical needle for medical use for suturing a relatively small and small wound.

[0002]

2. Description of the Related Art Conventionally used medical suturing needles of this kind are those in which one end of a suture is tied to the tail of a curved needle, and the needle is held like a scissors during a surgical operation. Nip it with a needle device, pierce the needle from one side of the wound to the other side, hold the tip of the needle protruding to the other side of the wound with the needle device, and the thread attached to the tail In general, the thread end on the pull-out side is inserted and tied with the thread on the insertion side, and when the wound affected area is long, the above operation is repeated at appropriate intervals to suture the entire length of the wound opening.

[0003]

The above-mentioned conventional suturing means requires a needle holder particularly in the handling operation of a curved needle having a suture tied to the tail thereof, requires a considerable skill in the operation, and the tail of the needle. If the binding part of the suture thread connected to the needle is too large, it will cause problems when the needle is pierced, and there will be problems such as an increase in the wound opening when the needle is inserted. There is an inconvenience such as a need for an attachment structure and a troublesome step of binding the thread to the needle, and the use thereof is complicated to use for a small wound.

[0004]

SUMMARY OF THE INVENTION In view of the above, the present invention can be used as a suture for suturing a particularly small wound affected area, and can be operated manually without the inconvenience of using an instrument such as a needle holder during a suturing operation. It is intended to obtain a suture needle of a type that can be easily used, and that can be easily handled as a mode in which the needle and the suture are separated from each other, and has a sharp tip and is hollow over the entire length. At the base of the curved needle,
It is characterized in that a grasping piece having a guide hole communicating with the opening base end of the hollow hole by a taper is fixed, and a suture can be pulled out and inserted into the hollow hole of the curved tube needle through the guide hole.

[0005]

The medical suture needle according to the present invention can be used as a wound opening after a small incision operation such as an urgent laceration or swelling, or when a trocar catheter or the like is inserted and fixed during use or when the wound is removed after use. When suturing a relatively light and small wound, such as the one with the thumb and forefinger, hold the gripping piece.
As shown in (a), the tip of the needle 1 is pierced from one side of the wound, the tip of the needle is projected to the other side, and then, as shown in FIG. By inserting a suture thread a of a predetermined length that has been treated with a bacterium and projecting the tip of the thread from the tip of the needle on the other side, hold the protruding part of the thread a with your finger and pull out the needle 1 ( As shown in (c), the thread a is left with the thread ends of appropriate lengths positioned on both sides of the wound, respectively, and then the thread ends a, a on both sides are tied together as shown in (d). It closes the wound opening. If the wound opening is long, insert (a) the needle 1 as described above, (b) insert the thread a of appropriate length into the needle 1, and (c) thread a at appropriate intervals. Leaving needle 1 removed,
(D) A plurality of stitches may be performed by repeating the operation of binding the thread ends a on both sides a.

[0006]

EXAMPLE An example of a suture needle according to the present invention will be described with reference to FIGS.

Reference numeral 1 is a needle made of a suitable hard material, which is a hollow needle 1a having a sharp tip over its entire length, and is curved into a suitable shape to facilitate the piercing operation on the surface of the affected area.

The curved shape of the tubular needle 1 is shown by bending the front half as shown in the figure, but the curved shape is arbitrary.

Reference numeral 2 is a gripping piece made of a metal or a hard synthetic resin or the like, and the base portion of the tube needle 1 is embedded in the front end of the gripping piece so as to be integrally fixed to the gripping piece 2. By providing a guide hole 2a communicating with the opening base end of the hollow hole 1a of the needle 1 with the conical taper, the starting end of the suture thread a inserted from the guide hole 2a at the time of use follows the taper of the needle. The hollow hole 1a was smoothly introduced and inserted.

In the illustrated example, the gripping piece 2 has a cylindrical shape, and a recessed portion 2b is formed in the middle of the gripping piece 2 to prevent slipping when gripped with a finger and ensure gripping. The gripping is not limited to the cylindrical shape, and it is optional to appropriately grasp the shape such as a polygonal shape or a polygonal shape.

The tubular needle 1 to which the gripping piece 2 is attached and the suture thread a having an appropriate length are stored in a sterilized state so that they can be used in an emergency.

[0012]

According to the present invention, a suture is conventionally integrally bound to the tail so that the thread is continuously inserted together with the needle into the affected area, whereas only the needle is pierced into the affected area. It is possible to obtain a suitable suture needle having a completely different operation method from the conventional means in which a suture thread of a predetermined length is inserted into the needle and then only the needle is pulled out leaving the thread. Like without needing to use a needle holder, it does not require special skill because it is grasped directly with the fingertips by the grasping piece and only the needle is pierced and removed from the affected area, therefore the operation is remarkably simple, It is simple and the structure of the tube needle is simplified compared to the needle with thread,
Further, it does not require a troublesome step of binding the thread to the needle, and has an effect of being able to deal with an emergency procedure for suturing a relatively small and small wound.
