Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surgical suture holder having a holder for winding a thread of suture material.

A known holder of this kind has a folding sheet with a ring for winding the thread and a small support made of flexible elastic material into which a needle with which the thread is tied tightly is inserted (Western Germany). National Patent Application Publication No. 2700077). This holder is housed in a sterile cover with the folded card folded. Remove the folding card from the cover, open it, untie the thread from the ring, and finally remove the needle from the small stand.
A disadvantage of this retainer is that in order to remove the suture material, the folding card must first be removed from the sterile foil packaging and then the folding card must be opened. For this reason, the patient must hold it by hand during this time, which is cumbersome during surgery. Yet another disadvantage is that the suture material is stored inside the folded fold card and cannot be seen or recognized prior to opening the sterile foil packaging. .

In addition, a holder for surgical suture material whose holder is a flat card wrapped with thread (West German Utility Model No.
7122075) and a surgical suture holder (US Pat. No. 3,319,782) in which the holder is a folding card containing several pre-wound thread bundles therein. These holders have bends or cuts for fixing thread ends or needles. When the needle is fixed on the cardstock (Karton), it encounters a certain resistance from the cardboard when it is pulled out. This creates the risk of slipping and carrying small pieces of carrier material. In the case of thread wrapped around card, the thread must first be unwound from the card immediately before use. For this reason, there is a disadvantage that the needle and thread may become tangled while being removed from the holder, or loops or knots may be formed in the thread. Yarns removed from cardboard carriers of this type often have folds or deformations that reduce their tear resistance.

The object of the present invention is to provide surgical sutures that are particularly simple in structure, can be seen during handling, and can be handled visually and safely when the thread is being wound in the factory and when the user is untying the thread. An object of the present invention is to provide a holder for materials.

This problem consists of a holding body consisting of a flat disk,
Solved by a holder in which the peripheral surface of the flat disk forms a winding surface and the holder has a form suitable for fixing the end of the thread or the needle on or in the vicinity of the peripheral surface. It was done.

In the retainer according to the invention, the thread of suture material is wrapped around the periphery of the flat disc, so that the flat side of the disc is left open for the suture thread. Therefore, yarn folds are not formed by avoiding large turning angles. The thread can be continuously removed from the holder by pulling on one of its ends without becoming tightly cinched or entangled. What is important is that the winding surface of the holder has an angle of 90° or more with no sharp corners, and within this angle (anWinkeln), the thread bundles that overlap in multiple layers are When removing the thread from the
may occur.

The holder, on the peripheral surface of which the thread is wound, also serves at the same time to fix the end of the thread and one or several needles. There is therefore no need to equip the holder itself with cards or the like; the holder forms the only part of the holder. The flat side of the holder can be used, for example, to print instructions for use or indications of the type of suture material. This flat side is never partially covered by suture material and is therefore completely available for printing.

In a preferred embodiment of the invention, the holder is made of polymer foam. Such foam should be flexible so that the needle can be pierced and removed again without much force and without damage. The foam material should also have a certain elasticity so that the point of the inserted needle is surrounded by the foam material and held firmly. Foam materials meeting these requirements are known under the names Novopolen or Alvedit. The holder may be made of open or closed foam. The use of elastic foam has the advantage that even very low tension threads can be wound onto the holder without the risk of the entire wound thread falling uncontrollably. This feature is further improved by making the foam open-celled along the wrapping surface, so that the threads on the cell walls are supported by the easy anchorage of their fibers. .

According to a preferred embodiment of the invention, the holder has two substantially parallel sides and at least one rund front surface. The second part of the holding body
The front face has two cross-sections, each extending at an angle of about 30° to 60° with respect to the sides. These straight sections serve to temporarily fix the needle inserted therein. The needle can thus be easily located and removed without enlarging the space of the holder storage bag in a cumbersome manner.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a holder wrapped with surgical suture material.

The holder 10 consists of a foam disk having a constant thickness of approximately 4 mm. Main aspect of this disk 1
1 is a flat surface, on which the foam pores are closed. A peripheral surface 12 extends at right angles to the main surface 11 and is open to foam pores. The holder 10 can be produced by cutting out or punching holes in a belt-shaped or plate-shaped foam material.

The peripheral surface 12 consists of two parallel side surfaces 13 , one end of which connects with an arcuate front surface 14 and the other end with two straight cross sections 15 . The straight sections 15 each extend at an angle of about 40 DEG to the longitudinal axis of the holder and thus to the side surfaces 13 and merge with rounded points 16.

A cutout 17 is provided in side 13 for securing the holder to a suitable device during the application of surgical suture material. A suitable gripper of the device can be inserted into the cutout without interfering with the winding process. After the thread has been wound, the gripper is passed under the thread and removed from the cutout 17.

In the example described above, the distance between the side surfaces 13 relative to each other is 26 mm and the radius of curvature of the front surface 14 is 13 mm. The radius of the rounded portion of the tip 16 is 6 mm.

In this case, the peripheral surface 12 of the holder 10 is planar and perpendicular to the main surface 11. However, the peripheral surface may be grooved to prevent the yarn from coming off laterally.

The holder 10 has several cuts 18 pointing outward from the peripheral surface 12, into which the thread 1 is inserted.
9 ends can be fixed. The end of the thread secured in this manner is indicated at 20 in FIG. Thread 1 extending outward from the fixed end 20 of the thread
9 is wrapped over the peripheral surface 12 several times. The other end of the thread is attached to a needle 21 which is inserted into one of the cutting surfaces 15 of the peripheral surface 14.

The beveled cut surface 15 of the peripheral surface 14 has the advantage that the entire needle projection can be accommodated within the expected rectangular wrapping line of the holder 10 with a correspondingly large space. The holder 10 is therefore suitable for sutures of various lengths and needles of various sizes. Since the thread 19 is wound over the circumferential surface 12 and is not subject to sharp abrupt changes in direction and changes in direction at an angle of more than about 100°, it can be easily removed and set free by pulling on the needle 21. can be used. It is therefore not necessary to completely unwind the thread 19 prior to use. In this case, cut 18
It should be taken into account that the end of the thread fixed to one of the threads can be pulled out of the cut 18 with little force due to the flexibility of the foam.

Important product descriptions, such as information for the user, such as thread material, length, pharmacopeia indication, needle size, etc., are preferably displayed directly on one or both main surfaces 11 of the holder 10. This eliminates the need for an information display means that is housed in the packaging bag in the form of a separate piece of paper or the like. This information may be printed on an adhesive label or foil, which is then applied to the main surface 11.

The suture tool holder 10, which has suture materials 19 and 21 wrapped around its peripheral surface 12, is housed in a rectangular transparent packaging bag (not shown) to prevent bacteria from entering. When using the suture tool, the packaging bag is opened and the suture material holder 10 containing the suture material is taken out. Next, grasp the main surface 11 of the suture material holder 10 with your thumb and index finger, and insert the needle 21.
Remove the suture by pulling. Instead of a thread having a needle 21 firmly attached to one end thereof, a thread without a needle or with a needle at each end may be wound onto the suture holder.
