Embodiment Construction

[0043] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0044] Such as Figure 1 to Figure 17 As shown, the present invention provides a medical orthopedic puncher, which is used to punch holes in the corresponding parts of the bone of the patient to be operated. The orthopedic punch includes a bracket, a cantilever 5, a drilling drill 100, a driving mechanism and a plugging mechanism. Wherein, the cantilever 5 can be lifted and arranged on the support; the drilling bit 100 is arranged on the cantilever 5, and the drilling bit 100 includes an outer drill rod 1 and an inner support core 2, and the outer drill rod 1 is At least part of the elastic hollow rod structure has an insertion cavity 13 inside, and a cutting edge of...

Abstract

Disclosed is a medical orthopedic puncher, comprising: a bracket; a cantilever, which can be lifted and lowered on the bracket; a drilling drill, which is set on the cantilever, and the drilling drill includes an outer drill rod and an inner support core, and the outer drill rod is At least part of the elastic hollow rod body structure has an insertion cavity inside it, and a cutting edge with a helical winding structure is opened on the outer periphery of the rod body structure, and the inner support core is inserted into the insertion cavity to support the outer drill rod, so as to be compatible with the The outer drill rods are combined to form an integral drill bit structure; the driving mechanism is set on the cantilever to drive the drilling bit to rotate; the plug-in mechanism is set on the cantilever and connected with the inner support core for inserting the inner support core cavity or withdrawn from the insertion cavity. The orthopedic punch for medical use is convenient and quick to use, and the removal process after the drilling is completed saves time and effort, and prevents secondary damage to the bone at the drilling site due to the rigid extraction of the drilling drill bit, thereby ensuring that the drill bit in the orthopedic surgery High-quality and efficient hole work.
