Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a suture material (Naht material) (
7) A holder for surgical suture material having a holder for winding a thread.

A known holder of this kind has a folding sheet with a ring for winding the thread and a small support of flexible elastic material into which the needle with the thread tightly tied is inserted (West Germany). Patent Application Publication No. 2700077). This holder is stored 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. The disadvantage of this holder is that in order to remove the suture material, the folded card must first be removed from the sterile foil packaging.
Next, the folded card must be opened. For this reason, you must hold it with your hands during this time.
Annoying during surgery. Yet another drawback 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. .

There are also holders for surgical suture material (West German Utility Model No. 7122075) in which the holder is a flat card with thread wrapped around it, and a folding device in which the holder contains several pre-wound thread bundles. A surgical suture retainer (U.S. Pat. No. 3,319,782) that is a power cord is also known. These holders have bends or notches for fixing thread ends or needles. The needle is a piece of card (Kart)
on), it will experience a certain resistance from the cardboard when being pulled out. This creates the risk of slipping off and of small pieces of carrier material being carried away. 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 drawback that the needle and thread may become tangled during removal 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 a surgical suture that is particularly simple in structure, can be seen during handling, and can be handled safely while being visually visible when winding the thread in the factory and when the user unwinds the thread. An object of the present invention is to provide a holder for materials.

The problem is that the holder consists of a flat disk, the peripheral surface of the flat disk forms a winding surface, and the holder fixes the end of the thread or the needle on or near the peripheral surface. Solved by a holder with a form suitable for □″: cut.

In the retainer according to the invention, the threads of suture material are 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 end so that it does not become tightly tightened or tangled (it can be continuously removed from the holder). It is an angle that is larger than that and the corner is not sharp, and within this angle (an Winkeln), when removing the thread from a bundle of threads stacked many times over, there will be ay (Verkln).
ertmungen) 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.

Therefore, there is no need to equip the holder itself with cards, etc.
The holder is the only part of the holder (dam einz ig
e Teil). 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 polymeric foam (
Also note the product made by Polymerschaumstoff. 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 tip of the needle is surrounded by the foam material and held firmly. A foam material that meets these requirements is Novopolen V7.
It is also known as Alvedit. The holder may be made of open or closed foam.

The advantage of using elastic foam is that even threads with very low tension can be wrapped around the holder without the risk of the entire wound system falling uncontrollably. The material is wrapped in an open cell shape (
o'f fen! It is further improved by making the fibers easier to anchor, so that the threads on the cell walls are supported by easy anchoring of the fibers.

According to a preferred embodiment of the invention, the holder has two substantially parallel sides and at least one rounded (r
und ) has a front surface. The second front surface of the holder has two cross-sections, each extending at an angle of about 30' to 60' relative to the side surface. These straight sections serve to temporarily secure the needle that is inserted therein. The needle can therefore be easily located and removed without enlarging the space in the holding 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 αG consists of a foam disc with a constant thickness of approximately 4 mm. The main surface αD of this disc is flat;
On the surface the foam pores are closed.

The peripheral surface α extends perpendicularly to the main surface αυ, and the foam pores are open in the peripheral surface. The holder αC can be produced by cutting out or perforating a belt-shaped or plate-shaped foam material.

The peripheral surface a2 consists of two parallel side surfaces αQ, one end of which is connected to one arcuate front surface (1Φ), and the other end is connected to two straight cross sections 05. do.

The linear cross-sectional views are each aligned with the longitudinal center axis of the holder, and therefore with the side surface 0.
■ Extends at an angle of approximately 40° to the rounded tip α
Unite with e.

A cutout 0'7) is provided in the side surface 03) for securing the holder to a suitable device during the wrapping of surgical suture material.

A suitable gripping tool of the device can be fitted into the cutout without interfering with the winding process. After the wrapping of the thread is completed, the gripper is passed under the thread and removed from the cutout.

In the case of the above example, the distance between the side surfaces αJ is 26 m.
m, the radius of curvature of the front surface is 13 mm. Point (1
The radius of the rounded part in 6) is 6 mm.

In this case, the peripheral surface α2 of the holder (101) is planar and perpendicular to the main surface (1υ).However, the peripheral surface may be grooved to prevent the yarn from coming off laterally.

The holder αO has several cuts a8 facing outward from the peripheral surface α2, into which the ends of the threads (19) can be fixed. The part is indicated by a kiln in Figure 1.The thread extending outward from the fixed end (■) is wrapped around the peripheral surface (1) many times.The other end of the thread is wrapped around the needle (2). The needle is attached to one of the cut surfaces a9 of the peripheral surface (14).

The oblique cut surface α9 of the peripheral surface I has the advantage that the entire needle projection can be accommodated within the expected rectangular wrapping line of the holder αl with a correspondingly large space. The holder [11 is therefore suitable for suture threads of different lengths and needles of different sizes. Since the thread (II) is wound on the peripheral surface 1z and does not undergo sharp abrupt changes in direction and changes in direction at angles greater than approximately 10 (f), it can be easily removed by pulling on the needle (II) and free Therefore, it is not necessary to unwind the thread completely before use.In this case, the end of the thread fixed on one of the cut sides can be used to cut the thread due to the flexibility of the foam. It should be taken into consideration that it can be pulled out from the α mark with a small amount of force.

Important product descriptions, such as the material and length of the thread, should preferably be displayed directly on one or both sides of the drug substance (U), so that it can be stored in the packaging bag in the form of a separate piece of paper, etc. Information display means (Information
str'fger) is no longer needed. These information may be printed on an adhesive label or foil, which is then applied to the main surface aD.

Suture materials 09 and 01 wrapped around the peripheral surface a2
1 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 αD of the suture material holder with the thumb and forefinger and remove the suture material by pulling the needle (21). Instead of a thread with 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.
