Description

Medical head for wound closure

FIELD OF THE INVENTION The present invention relates to a medical multiple for wound closure which is bent to at least one point in S20 and to a method for forming such a medical multiple.

Many surgical solutions are known to treat wounds. Ancient Greek doctors used as a surgical aid a wound joint on a Mediterranean beetle (Soadtes bopehus FoM,) that the edges of the wounds were pinched with the length and strong jaws of this beetle, and then clenched in the upper lobe of his body. closed the wound. This was followed by a thread attached to the needle, followed by different varieties and types

alternative

does not require a ton of absorbable and non-absorbable, 1 wound closure which gives a very good functional and aesthetic rt.

Patent No. 5,123,198 discloses a hook made from hooked pumpkin that does not require the use of yarn, provides a wound closure device that dates and enhances wound closure and provides a shorter healing time than prior art devices,

The present invention is based on the discovery that, by applying adhesive suitable for tissue fixation in the wound environment, a stable closure of the wound edges can be promoted, which also reduces the healing time.

According to the invention, the object is solved by a medical needle which is curved at least at one point and which

The invention further relates to a method of forming a needle according to the invention, which comprises bending a straight injection pen at least at one point.

Certain preferred embodiments of the invention are defined in the appended claims,

Further details of the invention are illustrated in the following examples by way of illustration. Explained. In the drawing it is

Figure 1 is a cross-sectional view of a preferred embodiment of the medical stick 10 according to the invention. In this embodiment, the injection stick, any tubular or solid needle, is suitable for carrying out the inventive stick 10. The 10 injection vials consist of 12 main portions and 14 cousins. The dagger 12 is bent at points 16 and 18 at o and β, respectively

The two points 1 and 2 divide the main part 12 into a mandrel 20, one center .22 between the two points 16 to 18, and a needle 26 towards the needle tip 24, respectively. their extensions intersect. The divergent or parallel stems 20 and 26 facilitate the insertion of the needle tip 24 into the tissue around the wound to be joined. However, the position of the stems 28 is not necessarily divergent - depending on the size and depth of the tissue to be secured, the distance between the cone 14 and the needle tip 24 should be chosen when introducing it into the tissue. For fastening thicker or deeper tissue, it is desirable for the mandrels 26 to be spaced apart and for a greater distance between the cone 14 and the needle tip 24, for thinner tissue a smaller distance between the cone 14 and the needle tip 24 is sufficient. It is clear that thorns 20 and 26 can meet the above criteria even at different angles of α and β. Preferably, the angle β formed at the point 18 of the bend toward the needle tip 24 is preferably at least about. 38 ^c , more preferably at least approx. 76 ", more preferably approx. 75-145 °, more preferably approx. 85-120 °, most preferably approx. 11h ^ö strength. The α angle is also preferably at least about 3 O ^c ~ os, however, may be less, is substantially next to a sufficiently large value of the β angle, as it is also conceivable to parallel to the needle shaft 20 and 28, or diverge, or the 14 cone and 24 depending on the tissue to be secured, the proximity of the cone 14 and the needle tip 24 still does not prevent the proper use of the needle 10.

In the case of the two bending points 16 and 18, the bending point 16 and 18 advantageously divides the saw 12 into the fact that the cone side needle shaft 20 is considered to be 1 unit and the middle needle section 22 is preferably 0, .5-0.7 units; the bar 26 facing the needle tip 24 is preferably 1.2 to 1.5 units. The total length of the needle 10 depends on the type of tissue to be joined and the nature of the wound to be closed.

In the embodiment shown in Fig. 1, the pins 20 and 28 of the needle 10 and the needle section are in the same plane, however, it is not necessary that the pins 20 and 26 or the section 22 may define a three-dimensional configuration. This is also true for 10 needles bent at more than two points below

As mentioned above, the needle 10 of the present invention may not only be designed as an injection needle, but may also be a tubular or solid needle bent at any angle. It is also not a requirement that the section defined by the points 18 and 18 of the bending of the needle 10 be straight, for example the central section 22 may be curved, the ends thereof being angled at the ends of the curved section 22 tangents and the 20 and 28 loesses

Fig. 2a illustrates the needle 10 of Fig. 1 when fusing 32 wounds in tissues 30 (e.g., skin, fat, muscle, etc.), guiding the needle 24 of needle 10 through the tissues 30 to be united, and across the wound 32. and the aces 10 and 20 are folded over each other and thus

-4 pin the wound edges and close the wound 32. When folding the mandibles 20 and 26, the angled needle 10 is not bent anywhere but at the driving points 16 and 18, i.e., the α and β angles will decrease further, preferably about 30 * value.

As can be seen, the advantage of using an angle bend 10 of the invention is that the tissues 30 are substantially subjected to lateral compression, so that the middle lip 22 does not compress the tissue 30, thus providing the tissue 22. through the compression-free section around the wound 32, blood circulation to the tissues 30 is satisfactory, resulting in faster wound healing, in the mini-sealing technique 40 of the prior art illustrated in Figure 2b. The ends of the thread 40 protruding from the tissue 30 close the wound 32. As can be seen, the thread 40 passing through the tissues 30 takes the form of an oval or circular arch within the tissues 30, thereby contracting the tissues 30 along its entire length in the direction of the arrows 34 shown in this figure. Thus, the 40 threads greatly reduce blood circulation around the 30 wounds, which is slower

Fig. 3 shows a further embodiment of the pile 10 according to the invention, in which the saw blades 12 are bent at a single point 18 at an angle β which divides the saw 12 into the canoe 20 and the needle tip 26. Here again, the angle β is preferably in the range of the above objects,

In Fig. 4, the 10 waves of wobble 10 are shown when the wound 32 in tissue 30 is united during use.

Introduced through tissue 36 and outputted through the pho-phalanx of wound 32, the hostage 10 of the WW 10 is folded back in the direction of the mandrel 14, thereby tightening the wound edges of the mats shown and closing the wound 32. By folding the stem 26, this angle is preferably reduced to at least 30 * stones. Even with such a single point bent 10, the compression in the weft 30 is significantly reduced, thus applying a greater degree of weaving compared to this conventional thread 40.

The needle 10 of the present invention may have more than two drive points 16 * as shown in Figure 6. By using a plurality of core twists 16 * points ~ 5 ~, a hook-like shape can be achieved, which, however, is guided into the fabrics 30 and twisted from the fabric 30, it deforms randomly.

By forming the needle 10 of the present invention as a needle 10, the cone 14 is connected to a syringe and allows the needle adhesive 30 to be inserted into the tissue 30 via the tubular mandrel 12 while inserting the needle tip 16 of the wound closure. closing.

Embodiments of the needle 10 of the present invention in which one or more bending points 16, 18, 15 'divide the mandrel 10 into straight sections can be readily formed at any α, β angle of the injection needle or tubular or solid needle. by driving.

The wound dressing with the 16 needles of the present invention does not require any particular skill. The needle 10 is primarily designed for temporary wound closure in emergency, but can also be used for permanent closure. During the operations described below, it has been found that suture prototyping of the suture (making a suture image by pinching the edges using the needles 10) can also be performed using the suture technique provided by the present invention.

Examples

In 2008, in 9 cases, we tested the seam with the inventive pump 10 and its properties. Infant, middle-aged, and elderly cadavers, followed by surgery. The material used is disposable sterile injection needles, sterile gauze, adhesive plaster. Wounds of different sizes and depths were dropped on cadavers at different locations to determine whether they were capable of combining large and deep wounds.

The injection pump used as needle 10 was twisted 90 degrees twice before puncture and, after penetrating the cuton and subcutaneous line, was bent from needle 26 at needle tip 10 to needle 14 at pin 14 (Figure 7). After unification, a sterile bandage was used. We put this stitch on the chest to test its strength. We found that only 10 needles could hold the body of the corpse.

Applying the technique on my own, I inventor for 10 days per primate

The seam exception (the exception of the 10 pumpkins) is one thousand and fast.

The shotguns according to the invention are suitable for temporary fixation.

In another case, upper limb tympanic edema syndrome is performed by rotating the lobes, partially joining and temporarily closing this wage using the degree of the invention, which is

Following the evacuation of a hematoma following Ratelie's myelization, the wound edges were also fixed at 10 degrees to the final healing angle of the invention.

Results

The joint is fast, efficient, requires minimal material (gauze, adhesive plaster). The seam technique of the invention with carbon pump 10 is less traumatic and can be loaded with painful tension. Well used for temporary fastening and planning in flap training, quick to execute, no damage to flap edges. If not used as a temporary fixation, the time and quality of shielding is similar to these seams. It is also suitable for replacing situational stitches with non-sterile brushes.

It will be appreciated that alternatives to other embodiments disclosed herein may be contemplated by those skilled in the art and are within the scope of the present invention.
