Abstract

The application discloses a lifting method of a facial ligament, which comprises the following steps of S1, accurately marking a subcutaneous attachment end or a body surface projection area corresponding to a target facial ligament on the surface of facial skin based on facial anatomy positioning and anatomical running of the target facial ligament, thereby accurately focusing acting force on the target ligament through a special instrument based on facial anatomy positioning and avoiding damaging surrounding tissues. The whole process is only operated on the surface of the skin, does not need incision and implantation, thoroughly avoids surgical wound and wire foreign body risks, can effectively conduct composite force to deep ligaments, enables the deep ligaments to generate controllable folding deformation, realizes stable fixation through a subsequent biological healing mechanism, fundamentally improves ligament relaxation, has a more natural and durable effect, greatly improves operation safety due to the fact that skin breaking is not needed and energy is controllable, and aims to optimize experience and ensure comfort level of the process due to dynamic regulation of mechanics and optional hot-cold cooperative procedures.

Claims (7)

  1. 1. A method for lifting a facial ligament, comprising the steps of: S1, accurately marking the subcutaneous attachment end or the body surface projection area of a target facial ligament on the surface of facial skin based on facial anatomical positioning and anatomical walking of the target facial ligament, wherein the marking range is adapted to the distribution width of the target ligament; S2, applying a pressing force perpendicular to the skin surface or an oblique pressing force forming an acute angle with the skin surface to the marking area through an external instrument capable of accurately fitting the facial contour, and simultaneously applying a shearing force parallel to the skin surface and pointing to a preset lifting direction, wherein the pressing force and the shearing force cooperate to form a composite resultant force, the resultant force penetrates through epidermis and dermis layers and is accurately transmitted to a target facial ligament, and the acting force can be dynamically adjusted according to the ligament tissue thickness and the elastic characteristic; S3, under the continuous action of the composite resultant force, the target facial ligament is subjected to controllable plastic bending or folding deformation at the periosteum attachment position or the fascia connection position, the deformation degree is controlled within the tissue physiological tolerance range, and meanwhile, the attachment points of structures such as subcutaneous soft tissues and fat pads attached to the upper end of the ligament are driven to generate directional displacement along the preset lifting direction, so that the accurate lifting of the facial soft tissues is realized; And S4, maintaining the ligament folded state in the step S3 for a certain time, and promoting fibrous connective tissue proliferation and adhesion at the ligament folded position through continuous mechanical fixation to realize stable biological fixation of the target ligament in a folded state.
  2. 2. The method according to claim 1, wherein the external device in step S2 is an ultrasonic pressure coupling head with a specific contact surface, and the contact surface is made of biocompatible material, and the shape of the contact surface is adapted to the shape of the target area, so that the contact surface can closely fit the facial contour and the ligament anatomy trend of the target area.

Description

Facial ligament lifting method Technical Field The application relates to the technical field of cosmetology, in particular to a lifting method of a facial ligament. Background One of the core goals of the facial rejuvenation cosmetic program is to achieve an effective, durable and natural elevation of facial soft tissues. With a thorough understanding of changes in facial anatomy during aging, particularly laxity, lengthening and impaired support function of facial ligaments (e.g., zygomatic arch ligaments, mandibular ligaments, etc.) are believed to be key factors leading to facial soft tissue sagging, blurring contours, and intervention of ligaments has become an important development in this field. At present, cosmetic solutions aimed at improving facial ligament laxity and soft tissue sagging are mainly divided into the following categories, but all have certain limitations: The pull Pi Shu is a conventional means of achieving contour remodeling by extensive subcutaneous dissection, direct suspension or folding of the suture ligaments and fascia layers. Although remarkable and durable, this solution is traumatic, long in recovery period, high in risk of operation, and extremely demanding in terms of anatomic knowledge and skill of the practitioner, and more importantly, it is usually a physical severing, refastening or folding suture of the ligament, irreversible in process and difficult to fine control the degree of deformation. Minimally invasive interventional procedures (e.g., wire carving, small incision lifting) that pull up soft tissue by implantation of absorbable wires or limited dissection. Although the trauma is relatively small, the action mechanism of the device mainly depends on the physical traction of foreign matters (such as barb wires) or fiber wrapping generated by short-term inflammatory reaction, the morphological change of the ligament is limited, the effect durability is insufficient, the risks of wire displacement, penetration or unnatural facial expression can exist, and the vector and the force of the lifting are difficult to accurately and dynamically adjust according to the biomechanical characteristics of individual ligaments. Content of the application The present application aims to solve the technical problems in the related art at least to some extent.
