Abstract

The invention relates to a dynamic cutter head, which consists of a cutter body, an outer sheath tube, an inner cutter core, an inner cutter seat, an outer sheath seat, a reset sleeve, a reset spring, and a connecting sleeve. A ball joint is arranged in the outer sheath seat. The front end of the blade is provided with a ball joint, which matches the inner knife seat, and a support spring is installed on the rear end, and the support spring matches the ball joint. The invention has the advantages of reasonable structural design, small friction between knife tubes, low noise, less heat generated by friction, and can buffer and release mechanical waves generated during work.

Description

technical field [0001] The invention relates to a power cutter head, which belongs to the field of medical instruments. Background technique [0002] Existing power cutter head is made up of cutter body, outer sheath tube, inner cutter core, inner cutter seat, outer sheath seat, reset sleeve, reset spring, connecting sleeve, wherein, cutter body is divided into cutter head and inner core and is arranged on The front end of the inner knife core is covered with an outer sheath tube, the outer sheath tube clamps the outer sheath seat and the connecting sleeve, and the bottom of the connecting sleeve is provided with a reset sleeve. When this power cutter head is working, the inner knife There will be friction between the core, the inner knife seat, the outer sheath seat, the reset sleeve and the connecting sleeve, which will generate heat, which will cause the tool to heat up, and there will be noise. Contents of the invention [0003] The technical problem to be solved by t...
