The invention relates to the technical field of medical instruments, in particular to a temporal-mandibular joint anterior baffle prosthesis with a porous structure, which comprises a baffle plate, a lateral cranium fixing wing and a zygomatic arch fixing wing which are respectively fixed on a temporal bone scale part and a zygomatic arch, and the bottom of the baffle plate is a cambered surface and is used for fitting and limiting excessive forward movement of a mandibular condyle process. The whole prosthesis is made of a titanium alloy and PEEK composite material, and is provided with a bionic bone tissue porous structure and through holes which are distributed all over the whole, so that the lightweight structure is realized, the bone compatibility is improved, and the osseointegration is promoted. The problems that an existing prosthesis is large in weight, poor in bone compatibility, prone to causing bone degeneration and the like are solved, the prosthesis has the advantages of being light in weight and good in biocompatibility, the comfort and the osseointegration effect are improved, and postoperative discomfort and secondary operation risks of a patient can be effectively reduced.

This invention discloses a mouse control method, medium, and device based on head posture recognition. It acquires a facial image and collects key feature points of the zygomatic arch, eyebrows, nose tip, and mouth. Based on the geometric relationship of these key feature points, it determines the head posture movement data in the horizontal and vertical directions. Based on the vector relationship of this movement data in a pre-established Cartesian coordinate system of the facial image, it calculates the mouse offset and controls the cursor movement accordingly. Based on the key feature point of the mouth, within a continuous fixed frame cycle, a mouse click event is triggered when the distance difference between the two corners of the mouth remains consistently greater than a set distance threshold. Advantages: Applicable to a contactless scenario, especially in the field of accessibility applications, it strengthens the solution to the problem of inconvenience for disabled users and has a certain degree of fun, with a broad market potential.

The present application relates to the field of cosmetic technology, in particular to a filling and shaping injection method based on improving facial aesthetics, which identifies target areas according to individual three-dimensional morphological assessment or digital assessment results, includes a facial support system, a volume system and a contour system, selects at least one system in the target area based on the type of aesthetic defect, and selectively implements one or more injections; the facial support system includes eyebrow arch, malar arch, temporal region and mandibular angle region; the volume system includes forehead, cheek and neck; the contour system includes nose, chin, lower jaw edge and ear base; according to the physiological structure and shaping needs of different parts, the injection material is accurately selected and the dilution ratio is determined, laying a foundation for shaping effect. The filling agent stock solution or suitable proportion diluent can provide stable support and / or improve texture due to its own material properties, and good compatibility with the surrounding tissue after injection.
