Production methods triangle ultrasonic osteotome blade cutter

  In orthopaedic surgery, often using ultrasonic treatment on bone cutting, grinding, planing, scraping or any plastic.The ultrasonic osteotome cutter tooth has wide blade section and the main cutting part and part of blade is not more effective. The problems of the ultrasonic osteotome blade are as follows:  slower cutting speed, low efficiency, poorly load ability , waste of energy; easy to fracture, low service life; complicated shape and high difficulty of processing, the higher production cost.

The utility model aims to propose a triangular ultrasonic osteotome blade cutter , can improve the cutting speed and reduce the operation time, and to precisely control the amount of bone cutting and shapes. For this purpose, the utility model adopts the following technical scheme of the triangular blade Piezosurgery blades, including blade and tip, the tip being located at the front end of the blade, the center located at the tip of the tip of the longitudinal central axis , center between the two edges of the blade near the tip of the central part of the triangle, close to the blade edge portion is arc-shaped groove. The thickness of the tip of the blade is greater than the thickness of the blade. The angle between the horizontal line near the central portion of the tip of the triangle edges and center is between 15 degrees to 75 degrees. The angle between the horizontal line near the central portion of the tip of the triangle edges and center is between 30 to 60 degrees. Comprising a blade and a connecting thread, the blade end of the blade is connected at one end with a threaded connection, one end of the blade is rough cylinder, one end of the cylinder is fine, by the middle of the arc transition, and set regular hexagonal wrench bits connecting thread for use with ultrasound transducer connection. Adopting the utility model of technical scheme, osteotomy high efficiency, speed, reducing surgery time and patient pain, doctors reduce labor intensity; head compact, precise control of the depth of cut and shape bone, surgery to reduce the cut bone loss, accelerate patient recovery time; hemostatic coagulation effect in the process of cutting bone, reducing blood loss; reduce the difficulty of processing and reduce production costs.

The main idea of the utility model program is on Piezosurgery tip shape of the structure, located on the central axis of the entire nose tip, so that the ultrasonic energy transducer generates all converge on the tip of a knife Piezosurgery tip portion (the most effective part of the work), converge to a point, so that the tip of the tip portion with the strongest energy output, the work to achieve the strongest effect. Triangular blade tip Piezosurgery structure are basically the same, except that the thickness between the tip of the blade is greater than the thickness of the blade tip and through the arc transition. So that in use the tip of the cutting width is greater than the thickness of the blade, during surgery, cutting thicker bones or cutting deep grooves folder knife stuck phenomenon does not occur when the window type incision. In addition, the large thickness of the tip also increases the tip strength, the relative increase tip life.

Using the utility a new technology solution that can improve the cutting speed and reduce the operation time, and to precisely control the amount of bone cutting and shapes.
