DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical needle packaging support for supporting a surgical needle having a substantially semicircular arc shape when the surgical needle is packaged.

[0002]

2. Description of the Related Art When wrapping a surgical needle of this kind, a support for supporting the needle is used. This type of support is
A needle holding section for holding the needle is provided. Conventionally, a needle holding member of this type uses a needle holding member formed of, for example, a block-shaped sponge. When the needle is held by the sponge, the tip of the needle is inserted into the sponge. By providing the sponge on the support, the needle can be easily held at a desired position, and since the structure is extremely simple, the support can be manufactured at low cost.

However, when the needle is held on such a sponge, the tip of the needle is stabbed into the sponge and comes into contact with the sponge, so that the sharp tip of the needle is damaged or the needle is coated with silicon. If there is, there is a disadvantage that the silicon coating is peeled off from the tip of the needle. Furthermore, the sponge is flexible, so that the holding state of the needle is not stable, and when a large needle having a relatively large diameter is pierced, the sponge itself is cut, so that it is difficult to reliably hold the sponge. was there.

In view of the above, there has been known an apparatus provided with a needle holder as disclosed in Japanese Patent Application Laid-Open No. 7-402, instead of the sponge needle holder. As shown in FIG. 6, this kind of needle holder 20 is injection-molded integrally with a synthetic resin support 21 (a part of which is shown in the figure), and a plurality of notches 2 are formed.
2 is formed in a wall shape extending upright on the substrate 23 integrally. By inserting the needle w into the notch 22, both edges of the notch 22 are deformed, and the needle w is held and held from both sides thereof.

[0005] However, such a needle holder 20 is provided with a needle w.
Is not only held at the bottom side of the notch 22, but also at the other portion (for example, the open side of the notch 22) through which the needle w passes when the needle w is fitted into the notch 22, the needle is expanded. There is an inconvenience that the holding of w is insufficient and the w is easily detached. Further, since this kind of needle holding portion 20 is formed on the substrate 23 by injection molding, an expensive mold is required to obtain a predetermined accuracy, and there is a disadvantage that the cost is high.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been developed in view of the above circumstances. The purpose is to provide the body.

[0007]

According to the present invention, there is provided a surgical needle packaging support for supporting a surgical needle, wherein the support is formed of a flexible synthetic resin. A flat substrate, and a needle holding portion formed on the substrate, wherein the needle holding portion is constituted by at least a pair of projections for holding the needle, and each projection is recessed from the back side of the substrate. The contact portion, which is formed so as to protrude on the substrate by being formed and contacts the needle when the needle is sandwiched, has a thickness dimension not more than the thickness dimension of the top of the projection. Features.

The needle holding portion is formed integrally with the substrate by protruding from the substrate. For example, a sponge for piercing and supporting a needle, a sticking tape for supporting the needle on the substrate in an attached state, etc. The other members can be eliminated, and the cost can be reduced. Further, each protrusion has a thickness dimension of an abutting portion that abuts on the needle, which is smaller than a thickness dimension of a top portion of the projection and is easily bent, so that the needle is pinched regardless of the outer diameter and shape of the needle. When this is done, the needle is flexibly adhered along the peripheral wall of the needle, and the top of the projection restricts the needle in the detaching direction, so that the needle can be securely held.

According to a first aspect of the present invention, the needle is formed in a shape curved substantially in a semicircular arc, and the projection forming the needle holding portion is formed by projecting the needle onto the substrate. A pair of first projections that abut on the outer peripheral side of the curved shape of the needle adjacent to each other, and a second projection that abuts on the inner peripheral side of the curved shape of the needle at a position corresponding to between the two first projections. It is characterized by having.

[0010] The surgical needle is formed in a shape that is curved in a substantially semicircular arc shape. When the needle held by the needle holder swings or rotates, for example, the needle tip rises in a direction away from the substrate. The needle tip may be damaged by being caught on other parts. Therefore, in this aspect, a pair of first protrusions and a second protrusion facing between the two first protrusions are provided, and the pair of first protrusions abuts on the outer peripheral side of the curved shape of the needle,
Since the second protrusion comes in contact with the inner peripheral side of the curved shape of the needle, the needle held between the first protrusion and the second protrusion is
It is maintained in a posture parallel to the substrate, and can be reliably held on the substrate in a state where there is no shake or rotation.

In a second aspect, a plurality of the protrusions constituting the needle holding portion are formed adjacent to the substrate, and the protrusions are formed as a pair of first and second protrusions abutting on the outer peripheral side of the curved shape of the needle. One contact portion is provided on one side wall, and a second contact portion that contacts the inner peripheral side of the curved shape of the needle at a position corresponding to between the first contact portions of the other protrusions adjacent to each other is provided. It is provided on the side wall.

The projections of the needle holding portion in the second aspect are provided with a plurality of projections having the same shape adjacent to each other in one direction, and hold the needle between the projections.

According to this, similarly to the first aspect, a pair of first projections of one of the projections adjacent to each other is formed.
Since the projection abuts on the outer peripheral side of the curved shape of the needle and the second abutment portion of the other projection abuts on the inner peripheral side of the curved shape of the needle, the needle held between the two projections is , And can be reliably held on the substrate in a state where there is no shake or rotation.

Further, the projection in the second aspect has the first contact portion on one side wall and the second contact portion on the other side wall.
Since the abutment portion is provided and the needle can be held between the plurality of protrusions, the distance between the needles can be made relatively small to form a compact support.

In the present invention, the substrate is formed of a synthetic resin having thermoplasticity, and each projection of the needle holding portion is softened by heating the position of the needle holding portion of the substrate. Later, the projections are formed on the substrate by recessing from the back surface side of the substrate by using a mold having a curing temperature of the substrate and having a molding projection having substantially the same shape as each projection.

In the case of forming a projection which is recessed from the back side of a flat plate made of a synthetic resin having thermoplasticity, such as the above-mentioned substrate, generally, the portion which has been softened by heating is removed. Vacuum forming is used in which a protrusion is formed by suction swelling from the surface side to a shape corresponding to the protruding shape. Accordingly, when the protrusion is formed, the top portion is thinner than the contact portion, and the contact portion is not easily deformed when the needle is held, and the top portion is deformed and the needle is easily dropped from between the protrusions.

In contrast, according to the present invention, each projection is
It can be easily formed into a shape in which the thickness of the contact portion is equal to or less than the thickness of the top portion. That is, when the forming convex portion of the mold, which has been set at the curing temperature of the substrate, is brought into contact with the formation position of the needle holding portion of the substrate softened by heating,
The contacted portion of the substrate first begins to cure. Further, when the substrate is recessed by the molding protrusion, the thickness of the hardened portion hardly changes due to the contact of the molding protrusion at first (without being stretched thin), and the surrounding softened portion becomes thin. The projection is formed by stretching. At this time, a portion which first comes into contact with the molded convex portion and is hardened forms a top portion of the projection, and a thinly extended portion becomes a contact portion of the projection. Then, the contact portion of the protrusion, which is a thinly stretched portion, contacts the molding protrusion, and the contact portion is hardened. As described above, each protrusion can easily form the contact portion formed to be equal to or less than the thickness of the top portion only by indenting and molding the substrate by the molding projection of the mold at the curing temperature of the substrate. Can be.

Further, in the present invention, a fold line is provided from one end of the substrate to the other end of the substrate through the vicinity of the needle holding portion so as to bend the substrate in the back direction. It is characterized by having.

This kind of surgical needle is gripped by a needle holder when it is removed from the needle holder. At this time, by bending the substrate in the back direction (mountain fold from the vicinity of the needle holder) via the fold line, the lower part of the needle held by the needle holder can be opened, and the needle by the needle holder can be opened. Can be reliably held.
