2. Description of the Related Art In a surgical operation, a blood vessel around an affected area to be excised is ligated with a thread, and an incision site is sutured with a thread. For ligating or suturing an incision site of a blood vessel, a suture needle to which a thread is attached is grasped and operated with a needle device or a ligature suture guiding tool to pass the thread between tissues or into the tissue,
It is performed by pulling out the thread that has passed through the tissue to the practitioner side and tying it.

When performing ligation or suturing, the practitioner holds the needle holder in one hand and passes the suture needle between or through the tissues, and then the operator holds the needle holder and pulls out the suture needle. Will be done. Therefore, when the site to be ligated or the site to be sutured is deep inside the body, it is difficult for the practitioner to operate, and a ligature or suture tool that can be quickly and reliably performed with one hand is used. Development is required.

[0004] For example, the suturing device disclosed in Japanese Utility Model Publication No. 5-11850 is intended to meet the above-mentioned requirements, and a suture needle provided at the tip by operating a handle and a trigger, which are manual parts of forceps, with one hand. Is operated to ligate or suture the surgical site.

[0005]

When a blood vessel is ligated by using the suturing device, it is required to perform a two-step operation including a suturing operation by a suture needle associated with a handle operation and a thread grasping operation associated with a trigger operation. To be done. For this reason, the complexity of the operation cannot be eliminated when performing ligation at an extremely narrow site, and the development of a device that can be ligated by a simpler operation is desired.

The present applicant has developed a medical threading device that solves the above problems and has already applied for a patent (Japanese Patent Application No. 6-12).
No. 4947). However, even this technique is not perfect yet, for example, when a threaded needle is attached to the threading device, the needle is in a substantially upright state, and thus the threading device is slightly opened when performing ligation or suturing. Therefore, it is necessary to reach a ligation site or a suture site at a deep position in the body, and there is a problem that workability is difficult.

An object of the present invention is to provide a threading needle guide tool capable of holding a threading needle with a pair of jaws closed and raising the threading needle as the jaws are opened. To do.

[0008]

Means for Solving the Problems In order to solve the above-mentioned problems, a threaded needle guiding tool according to the present invention is a medical threading needle guiding tool having a pair of jaws. In addition to providing a needle stand portion capable of standing a needle with a needle, a needle receiving portion that receives the needle with a thread when the needle with a thread is raised in the needle stand portion of the other jaw and the pair of jaws is closed,
Further, a needle accommodating portion for accommodating the needle with a thread is provided continuously with the needle stand on the mating surface when the pair of jaws are mated.

In the above-mentioned thread needle guide tool (hereinafter referred to as "guide tool"), a needle stand portion capable of standing the thread needle is provided in one of the jaws, and a pair of needle stand portions is provided continuously with the needle stand portion. By providing a needle accommodating portion capable of accommodating the threaded needle when the jaws are aligned with the mating surface of the jaws, when performing ligation or suturing, the thread accommodating needle is attached to the needle accommodating portion with the pair of jaws being combined. Can be accommodated. For this reason, even if the affected area is deep inside the body, the threaded needle can reach the affected area without being dropped or disturbed by other tissues on the front side.

When reaching the vicinity of the affected area, the pair of jaws are opened to raise the threaded needle accommodated in the needle accommodating portion to the needle stand portion, and then when the jaws are aligned again,
By passing the threaded needle rising to the needle stand to the needle receiving portion provided on the other jaw, the threaded needle can be guided from one jaw to the other jaw.

FIG. 7, FIG. 7 is a diagram illustrating another configuration example of the mating surfaces of the pair of jaws, FIG. 8 is a diagram illustrating another configuration example of the mating surfaces of the pair of jaws, and FIG. 9 is another example of the guide tool. It is a figure explaining.

The guide tool A shown in FIG. 1 has a pair of jaws 1 and 2 which can be brought into contact with and separated from each other.
For example, a needle stand portion 4 for raising the threaded needle 3 is formed on the jaw 1, and a needle receiving portion 5 for receiving the threaded needle 3 is formed on the other jaw, for example, the jaw 2, and the jaws 1 and 2 are closed. The needle accommodating portion 6 for accommodating the threaded needle 3 is formed on the mating surfaces 1a and 2a at this time, and the whole is formed in the shape of forceps, and ligation or suturing of the affected area is performed by performing the same operation as the forceps. It is configured to be possible.

As shown in FIGS. 6 (a) to 6 (c), the threaded needle 3 is constructed by attaching a thread 3b to one end of a main body 3a. The main body 3a is formed into a sharp tip so that it can easily be pierced when passing through the tissue of a living body, or a spherical tip 3a ₁ that can easily pass between tissues, and the jaw 2. It has a body portion 3a ₂ having a length sufficient to engage the needle receiving portion 5 and a rear end surface 3a ₃ . The thickness of the body portion 3a ₂ is not uniquely set, but the thread 3b is set according to the ligation site or the suture site.
It is set according to the thickness of.

The method of attaching the thread 3b to the main body 3a is not particularly limited, and the so-called caulking is performed by inserting the end of the thread 3b into a hole (not shown) formed in the rear end surface 3a ₃ of the main body 3a as shown in the figure. It may be configured as an eyeless needle, or may be configured as a so-called eyed needle.

The main body 3a is generally made of stainless steel, but it can be formed by injection molding of synthetic resin. In this case, the threaded needle 3 can be manufactured in one step by insert molding the thread 3b. Further, the main body 3a can be made of tungsten carbide or titanium alloy. In any case, the material of the main body 3a is not limited, and any material can be used as long as it has a strength such that it can penetrate tissue between or inside the living body and does not have a bad influence on the living body.

As the threaded needle 3, it is not necessary to separately form the main body 3a and the thread 3b, and it is also possible to use a so-called stainless thread integrated needle. This integral needle consists of body 3a and thread 3b
Is made of stainless steel, the main body 3a is hardened to a predetermined hardness by work hardening, and the yarn 3b is given flexibility by heat treatment.

The main body 3a may be formed in a straight needle shape as shown in FIG. 1 (a), and as shown in FIG. 3 (b), when the jaws 1 and 2 are brought into contact with each other, the threaded needle 3 is provided. It may be formed in a curved needle shape having a curvature substantially equal to the curvature of the circumference of the moving circle. Further, the tip portion 3a ₁ can be formed into a spherical shape depending on the tissue to be pierced, as shown in FIG.

When attaching the thread 3b to the main body 3a,
As shown in FIG. 4A, the rear end surface 3a ₃ of the main body 3a may be caulked at a part thereof to reduce the diameter of the main body 3a. As shown in FIG. Thread 3b
May be attached by adhesion or the like, and further, FIG.
As shown in FIG. 5, the rear end surface 3a ₃ side of the main body 3a may be attached by caulking it in a tapered shape over a predetermined length.

Next, the structure of the main part of the guide A will be described with reference to FIGS.
This will be described with reference to FIG.

A needle stand 4 is formed on the mating surface 1a of the jaw 1 at a position separated from the tip end side by a predetermined distance. The needle stand 4 may have a function of abutting the rear end surface 3a ₃ of the main body 3a to erect the main body 3a, and may be a flat surface or a surface on which serrated projections are formed. .

A hole 1b penetrating in the thickness direction of the jaw 1 is formed at a position corresponding to the needle stand 4, and the hole 1b is formed.
And the tip of the jaw 1 are connected to form a slit 1c. The hole 1b has a function of allowing the thread 3b attached to the main body 3a of the needle 3 to escape when the threaded needle 3 is set on the needle stand 4, and the hole 1b is smaller than the thickness of the main body 3a. Moreover, it is formed to have a diameter larger than that of the thread 3b. The slit 1c has a function of guiding the thread 3b into the hole 1b, and is formed with a size that allows the thread 3b to be easily inserted when the threaded needle 3 is attached to the guiding tool A.

In the needle stand portion 4 configured as described above, the rear end surface 3a ₃ of the main body 3a is applied to the flat surface of the needle stand portion 4 by applying a tensile force to the thread 3b inserted into the hole 1b. It is possible to hold the threaded needle 3 in an upright state by pressing it against the serrated surface. It is preferable to set the shape and configuration of the needle receiving portion 5 so as to allow a slight inclination and positional deviation of the threaded needle 3 that is erected on the needle stand portion 4.

A needle receiving portion 5 is formed on the jaw 2. When the main body 3a of the threaded needle 3 which is erected on the needle stand 4 is press-fitted during ligation or suturing, the needle receiver 5 is provided with the main body 3
It has a function of gripping and receiving a.

The needle receiving portion 5 is a mating surface 2a of the jaw 2 and is formed so as to face the needle stand portion 4 formed on the jaw 1. That is, the needle receiving portion 5 starts from a position substantially opposite to the hole 1b formed in the jaw 1, and has a width and a predetermined length slightly smaller than the thickness of the main body 3a (body portion 3a ₂ ) of the threaded needle 3. Is formed in the shape of an elongated hole penetrating the jaw 2 in the thickness direction with a certain length, and the needle receiving portion 5 is lengthened from the tip of the jaw 2 for the purpose of imparting elasticity to the needle receiving portion 5. A slit 2b penetrating in the direction is formed. Further, the edge of the elongated hole that constitutes the needle receiving portion 5 facing the jaw 1 is formed as a rounded surface so that the threaded needle 3 erected in the needle stand portion 4 can be slightly inclined and misaligned. Is preferred.

Therefore, when the jaws 1 and 2 are approached and closed from the state where the jaws 1 and 2 are separated and the threaded needle 3 is erected on the needle stand portion 4, the body portion 3a ₂ of the main body 3a receives the needle. It is pressed into the portion 5 and pressed against the needle receiving portion 5. Therefore, the main body 3a of the threaded needle 3 can be clamped and received by the needle receiving portion 5.

A needle accommodating portion 6 for accommodating the threaded needle 3 is formed on the mating surface 2a of the jaw 2. When the jaws 1 and 2 are closed, the needle accommodating portion 6 cooperates with the needle accommodating portion 6 to provide the threaded needle 3
And has a function of holding the housed state.

The needle accommodating portion 6 starts from a position which is the mating surface 2a of the jaw 2 and is substantially opposite to the hole 1b formed in the jaw 1, that is, continuous with the needle stand portion 4 and is thicker than the main body 3a. It is formed in the shape of a groove having a width and a depth which are equal to or greater than or slightly smaller than the length of the main body 3a.

Accordingly, when the threaded needle 3 is accommodated in the needle accommodating portion 6 and the jaws 1 and 2 are closed, the needle accommodating portion 6 is covered by the mating surface 1a of the jaw 1 and the needle accommodating needle 3 is accommodated. It is possible to prevent falling off from the portion 6 and to surely accommodate it.

The needle accommodating portion 6 is not necessarily formed only in the jaw 2, but the needle accommodating portion 6 can be independently formed in the jaw 1 by forming the groove in the jaw 1. In this case, only the needle receiving portion 5 is formed on the jaw 2 (see FIG. 7). It is also possible to form the needle accommodating portion 6 across the jaws 1 and 2 by forming partial grooves in the jaws 1 and 2 that divide the needle receiving portion 6 in the depth direction. (See Figure 8).

As described above, the thickness of the main body 3a of the threaded needle 3 is determined depending on whether the needle accommodating portion 6 is formed in one of the jaws 1 and 2 or formed over the jaws 1 and 2. It is also a design problem that should be appropriately set according to dimensional conditions such as the thickness of the jaws 1 and 2.
