123 results about "Ligature" patented technology

In surgery or medical procedure, a ligature consists of a piece of thread (suture) tied around an anatomical structure, usually a blood vessel or another hollow structure (e.g. urethra) to shut it off. With a blood vessel the surgeon will clamp the vessel perpendicular to the axis of the artery or vein with a hemostat, then secure it by ligating it; i.e. using a piece of suture around it before dividing the structure and releasing the hemostat. It is different from a tourniquet in that the tourniquet will not be secured by knots and it can therefore be released/tightened at will.

The invention discloses a digital indirect bracket bonding method based on 3D printing. The digital indirect bracket bonding method includes the following steps of: obtaining a digital dentition modelof a patient; accurately positioning a bracket in three-dimensional design software, carrying out outputting and 3D printing of a three-dimensional dentition model with the bracket; manufacturing a transfer tray; and placing the transfer tray on the dental surface of the patient after the transfer tray is internally provided with a bracket and carrying out conventional bonding. When a bracket ofwhich the undercut is not removed is used, an undercut is easily generated on a film pressing type transfer tray; a dislocation force is generated when the transfer tray is removed, and consequently the bonding interface of the bracket is damaged, which causes bonding failures. The undercuts in the gingiva direction and the occlusal surface (or incisal edge) direction are removed so as to preventthe generation of undercuts which cause bonding failures. 1 / 2 of the brackets with undercuts below the ligature wing in the proximal and distal directions are retained, so that the brackets are prevented from falling off easily after being placed in the transfer tray. Due to the design of removing partial undercuts, the falling-off rate of the bracket after bonding is reduced; the bracket is prevented from falling off in clinical operation; and meanwhile, due to the adoption of a full-package transfer tray, the bonding transfer accuracy is guaranteed.
