的に製造することができないといった問題がある。However, the above-mentioned device requires a large space due to the large size of the device due to its complicated structure, and the resin solution is removed by removing the rack around which the suture is wound for resin coating. Therefore, there is a problem in that a number of steps such as immersing in, and then drying are required, so that a suture having a hardened end cannot be manufactured continuously and efficiently.

However, there is a problem that the quality is not uniform.
The present invention is proposed in view of the above problems, and an object thereof is to reduce the size of the entire device, simplify the operation and the process, and cure the suture itself without coating resin or the like. It is an object of the present invention to provide an extremely useful surgical suture processing device that can be used.

As yet another embodiment, although not shown in the drawing, the suture thread is continuously drawn out instead of being intermittently drawn out as in the first embodiment, and heating is provided in the suture running area. The heating means that follows the running of the suture heats the suture while following the movement of the suture by synchronizing the reciprocating speed with the running speed of the suture. ,
When reaching a predetermined position, it may return to the original position and perform the next heating.

とせず簡単に折り取ることができる利を伴う。Also in this case, the suture thread having the hardened end can be continuously obtained. Further, as shown in FIG. 5, the hollow passage C3 in the heating element C5 is a portion P in the passage C3,
The suture thread 1 in the passage C3 may be heated stepwise by forming the diameter smaller than that of the other passage portion P1.
In this case, since the part P heats the suture thread 1 more strongly than the other part P1, that part becomes more brittle than the other part, and a device such as “scissors” is required for removing the needle H after the suturing operation. There is an advantage that it can be easily broken off.

The shape of may be triangular as shown in FIG. In this case, the portion of the outer peripheral surface of the suture thread 1 facing the side of the triangle can be heated strongly. In any case, the configuration of the heating element C5 and the shape of the hollow passage C3 are not particularly limited within the scope not departing from the gist of the present invention.

つながる。A defect detecting device 5 such as a fluff consisting of a contact type or non-contact type sensor is arranged downstream of the feeding rollers A1 and A2, and the detecting device 5 detects an abnormality of the suture thread 1. When it is detected, the driving of the feeding roller A1 is stopped and the portion concerned is removed, or when it is cut by a cutter, it is classified as a defective product, for example, the release position of the grip 6 is changed, and the recovery container is placed on the conveyor. If one is provided and sorting is performed by detecting the defect and changing the position of the container, the yield is improved and the inspection process is omitted.

It has an effect that a suture having a hardened end suitable for a surgical suture can be continuously and efficiently manufactured at low cost. Further, since it is not necessary to use a solvent or the like to form the hardened portion, there is an advantage that the working environment is not deteriorated.

限定されない。The present invention uses a thermoplastic synthetic fiber, that is, a synthetic resin which is plastically deformed by heat as its material, and by utilizing such a property, the portion is hardened by locally applying heat treatment. Examples of the suture thread applied to the present invention include nylon, polyester, and polypropylene, as well as biodegradable and absorbable materials such as polyglycolic acid, polylactic acid, and blends or copolymers thereof, polyparadioxanone, and polyparadioxanone. Examples thereof include caprolactone, but the material is not limited to this as long as it is a material having the above-mentioned properties.

Arbitrary surgical yarns such as twisted yarn (twist) and braid (blade) are configured. In the case of a braided one, a core yarn may be inserted depending on its size, but especially the braid whose cross section is difficult to be a perfect circle Effective for suturing. However, the processing by this apparatus may be performed by appropriately setting the conditions depending on the material and the required quality.
