Abstract

The invention relates to a flexible multi-core spindle drill for plastic surgery overcoming the problems that the original bone drill can only drill directly while failing in guiding and drilling holes, shaping and grinding curvedly, comprising a main spindle having spindle sheath jacked with bearing and concave keyway on double ends and being assembled with an O shape ring by a clamp spring and secured to the rear cavity of the case, a driven spindle assembled with a bearing, an O shape ring and water resistant ring in the front cavity which has a lock nut mounted on one end and a cam key column on the other end for connection with the concave keyway of the main spindle, a water overflow hole is provided in the front cavity, and a guiding tube is secured inside the spring chamber by the O shape ring and connects with the screw thread of the front cavity. The invention has reasonable design, high work efficiency, strong heat-sinking and wound-cleaning functions. It is safe, reliable and convenient for all kinds of complex plastic surgeries.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a multi-core flexible shaft drill for plastic surgery. Background technique [0002] At present, in plastic surgery, orthopedic drills are widely used. The positioning and connection of drilling holes for various traumatic fractures; the row of holes waiting to be drilled in the mandibular angle osteotomy removal operation; the operation of diseased bone or bone joint dislocation, displacement of traction and fixation holes, etc., are very useful for medical surgical drilling instruments High dependence, especially the quality of orthopedic drills in this type of operation, is the key to the success of the operation. It can greatly reduce the workload of doctors, shorten the operation time, improve the quality of operation, and reduce the risk of operation. [0003] In the past, the orthopedic drills used in this type of surgery were all straight drills, which could not be bent o...
