Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an ultra-tension reducing can absorb soft tissue area.

Background

Tension-reducing suture is a special suture means for debridement suture, mainly a suture means which is adopted for a wound with higher tension and aims to prevent the wound from cracking, when the wound is sutured, the tension for cracking the wound is released in a subcutaneous layer, when the skin is sutured, the skin layer cannot bear the tension and crack, and when the skin is healed, scars cannot be left. Current methods of wound closure and relaxation include: suture, glue pasting, skin nail stapling, external tension reducer drawing and the like. The suture tension-reducing suture has the problems of complex operation, long time consumption, higher requirement on operators, higher requirement on wires and the like. There are currently no effective strain relief devices placed in the incision.

Detailed Description

Embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

An ultra-tensionable absorbable soft tissue strip of the present embodiment, wherein: including soft tissue area bottom plate 1, soft tissue area bottom plate 1 upper surface is provided with one row of left gullet tooth 2 and one row of right gullet tooth 3, and this one row of left gullet tooth 2 and right gullet tooth 3 all take 1 length direction parallel arrangement of bottom plate along soft tissue, and soft tissue area bottom plate 1, left gullet tooth 2 and right gullet tooth 3 are makeed by degradable medical biopolymer material.

In the embodiment, the soft tissue band base plate 1 is provided with a detachable connection part 4 at intervals along the length direction, the soft tissue band base plate 1 can be detached from the detachable connection part 4 to form a plurality of soft tissue band assemblies, and each soft tissue band assembly is provided with at least two left hooks 2 and two right hooks 3.

In the embodiment, the upper end of the left tooth 2 is bent to the right, and the upper end of the right tooth 3 is bent to the left.

In the embodiment, the soft tissue belt assembly is provided with a hollow hole 5 which is communicated up and down at the position between the left hook tooth 2 and the right hook tooth 3.

In an embodiment, the degradable medical biopolymer material is polylactic acid.

In an embodiment, the detachable connection 4 is a crease.

In the embodiment, the average tensile strength of the left and

right teeth

2 and 3 is not less than 17N.

In the embodiment, the soft tissue band base plate 1 has a tensile strength in the width direction of not less than 35N.

As shown in fig. 1 and 2, the utility model discloses a soft tissue area bottom plate 1 length is unlimited, is formed along length direction concatenation by a plurality of soft tissue area subassembly, and every soft tissue area subassembly is 1cm at length direction ascending size, and the ascending size of width direction is 1.4cm, satisfies the free scope in super subtracts a suture incision both sides. The length of the soft tissue strip base plate 1 is selected according to the length of the incision.

The method of use of the device is explained with reference to fig. 3-6:

as shown in fig. 3-4, a part of a wound is large and cannot be closed, a surgeon can close two sides of the wound together by using the ductility of the skin through a certain technology to suture the wound, however, the skin has elasticity and can generate tension at the suture part, whether the operation scar is obvious or not is an important factor, the tension is required to reduce the scar leaving, the tension of the wound is required to be reduced, the wound healing scar without tension is required to be much smaller, and the point that modern cosmetic suture is very emphasized is. Modern tension relief sutures are anchored to the skin at a distance from the wound, followed by deep sutures, which allow the skin to be held together easily in the superficial layers. Later, the wound can be slowly smoothed along with the retraction of the force.

Draw lines (dotted line in the figure) for far away position in wound both sides as figure 4, then will the utility model discloses an ultra-tension-reducing absorbable soft tissue area puts into the wound, and the hook tooth is up, and skin tensioning with the wound both sides is close to, makes the skin of drawing the dotted line lean on together, and the skin uplift of wound both sides, at this moment, the hook tooth hooks skin from the wound inboard, makes the tension of skin act on hook tooth and soft tissue area bottom plate 1 to the skin tension of suture department has been reduced. If the hook teeth can hook the skin well, the ultra-tension absorbable soft tissue band can replace a suture for tension-reducing suture, and an operator can suture the skin on two sides of the wound directly. If the hook teeth can not hook the skin well due to factors such as wound shape and the like, suture tension-reducing suture is still carried out, namely, a suture needle passes through the skin at the dotted line to carry out tension-reducing suture, and then the skin at the two sides of the wound is sutured, as shown in fig. 5-6, in this case, the ultra-tension-absorbable soft tissue band can assist the suture tension-reducing suture to reduce the tension at the tension-reducing suture. Because the degradation speed of the PLGA material in vivo determines that the ultra-tension-reducing absorbable soft tissue band can maintain effective tension reduction for one year, compared with a method that the stress is completely acted on the skin of the incisions at two sides by the tension reduction of the suture, the device can transfer the stress of the incision at the opposite side to the bottom plate material. The PLGA material is finally metabolized into carbon dioxide and water, the tissue compatibility is good, the risks of infection, rejection and the like are avoided, and the complications are few.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, a plurality of modifications and decorations without departing from the principle of the present invention should be considered as the protection scope of the present invention.
