Description

Technical Field

[0001] This utility model relates to the field of medical aesthetic fine suture technology, and in particular to a bidirectional distal tension-reducing suture for soft tissue. Background Technology

[0002] Medical barbed surgical sutures are widely used in clinical surgery. Current barbed sutures are categorized into unidirectional single-barbed, unidirectional multi-barbed, bidirectional single-barbed, and bidirectional multi-barbed types. These materials avoid the knotting issue associated with traditional surgical sutures during clinical suturing, thus increasing the speed of wound closure. Currently, the barbs in these suture materials are all the same size. When the barbs are too large, to prevent snagging on the dermis and causing epidermal depressions, which would affect the aesthetics of the sutured surface, they are usually used in the deeper subcutaneous tissue. When the barbs are too small, the dermis is well-fixed and less prone to depressions, but deep fixation is unstable. Therefore, in delicate plastic and cosmetic suturing, it is impossible to reduce tension on multiple anatomical layers in a single operation using traditional barbed sutures. It is still necessary to use traditional non-barbed surgical sutures for layer-by-layer suturing to reduce tension, which increases the time required, reduces surgical efficiency, and increases the difficulty of the procedure.

[0003] This invention is convenient and simple to operate, requiring no knotting or suture removal. Large and small barbs are used to provide distal tension reduction to deep and superficial tissues respectively, with even and adjustable tension reduction force. This enhances control over tension generated by tissue movement, reducing the risk of scar widening or hyperplasia due to tension. Furthermore, the close proximity of needle puncture sites on both sides of the wound poses a risk of affecting blood supply to the surrounding tissue; distal tension reduction fixation increases the straight-line distance from the needle puncture site to the wound surface, reducing this risk. Summary of the Invention

[0004] The purpose of this utility model patent is to provide a bidirectional distal tension-reducing suture for soft tissue, which solves the problems in the background art of long operation time, high difficulty or high physician experience requirements for delicate plastic and cosmetic suturing of subcutaneous soft tissue distal tension reduction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a bidirectional distal tension-reducing suture for soft tissue, comprising an arc-shaped guide needle at both ends and a suture body, wherein continuous large barb segments and continuous small barb segments are respectively provided from the inside out between the smooth line in the middle section and the smooth lines at the outer and tail ends on both sides, with the large barb segments close to the smooth line in the middle section and the small barbs close to the smooth line segments on both sides.

[0006] Furthermore, the unilateral length of the inner segment deep subcutaneous soft tissue bidirectional large barb segment is set to 2-3 cm, and the direction is set outward. The unilateral length of the outer segment superficial subcutaneous dermis bidirectional small barb segment is set to 1-2 cm, and the direction is set outward. The lengths of the first, second, and third barbless segments are set to no more than 5 cm, and the second and third barbless segments are the same length. Attached Figure Description

Detailed Implementation

[0010] A bidirectional distal tension-reducing suture for soft tissue includes a first arc-shaped guide needle and a second arc-shaped guide needle at both ends, and a suture body. The first arc-shaped guide needle (1) and the second arc-shaped guide needle (6) are respectively connected to both ends of the suture body. The suture body includes a first inner segment of deep subcutaneous soft tissue bidirectional large barbed segment (4), a second inner segment of deep subcutaneous soft tissue bidirectional large barbed segment (9), a first outer segment of superficial subcutaneous dermis bidirectional small barbed segment (3), and a second outer segment of superficial subcutaneous dermis bidirectional small barbed segment (8). The first barbless segment (5) is defined as the area in the middle of the bidirectional barbless segment of the deep subcutaneous soft tissue of the inner segment without barbs. The second barbless segment (2) and the third barbless segment (7) are defined as the outer edges of the bidirectional barbless segments of the superficial subcutaneous dermis of the outer segment from the tail end of the bilateral arc-shaped guide needle. The length of the bidirectional barbless segment of the deep subcutaneous soft tissue of the inner segment is greater than the length of the bidirectional barbless segment of the superficial subcutaneous dermis of the outer segment. The bidirectional barbless segments of the deep subcutaneous soft tissue of the inner segment and the bidirectional barbless segments of the superficial subcutaneous dermis of the outer segment are oriented outward and have the same angle.

[0011] Furthermore, the unilateral length of the inner segment deep subcutaneous soft tissue bidirectional large barb segment is set to 2-3 cm, with the direction set outwards. The unilateral length of the outer segment superficial subcutaneous dermis bidirectional small barb segment is set to 1-2 cm, with the direction set outwards. The lengths of the first, second, and third barbless segments are set to no more than 5 cm, with the second and third barbless segments having the same length.

[0012] Furthermore, the main body of the suture is made of medical absorbable suture material or medical non-absorbable suture material, and the bilateral arc-shaped guide needles are made of 302 stainless steel or 304 stainless steel or black needles after surface treatment.

[0013] This design can be applied during the closure of open wounds. First, the suture is placed in the deep subcutaneous soft tissue. The large barb segment is then left in the deep subcutaneous soft tissue by horizontally puncturing both sides with the curved guide needle. The small barb segment is then left in the superficial subcutaneous soft tissue by vertically puncturing towards the skin with the curved guide needle. After tightening, the smooth suture is pulled taut and cut.

[0014] This design can enhance resistance to the tension generated by long-term skin and subcutaneous soft tissue movement during the delicate suturing process in cosmetic surgery, thereby preventing the risk of scar widening and hyperplasia due to wound tension.

[0015] This invention features a design that allows for long-term control of skin and deep soft tissue tension, and is simple and convenient to operate during surgery, reducing damage to surrounding tissues caused by repeated suturing and instrument clamping.
