[0003] In order to facilitate the minimally invasive surgical tool to be inserted into the narrow (for example 3 mm-15 mm) incision of the patient for surgical operation, the cutting knife or the drilling and milling head in the minimally invasive surgical tool of the prior art is elongated straight rod shape, but this A minimally invasive surgical tool that does not effectively cut and drill bony surfaces perpendicular to the skin of the incision (e.g., posterior aspect of the patella)
The free end of the cutting knife or drill bit of the minimally invasive surgical tool should be curved in order to operate on the posterior side of the patient's patella, but the curved cutting knife or drill bit is not easy to insert into the narrow incision, or during the insertion process, damage to soft tissue

The invention provides a multi-angle drilling and milling tool for minimally-invasive surgery. The drilling and milling tool comprises a first gear and a power shaft, a second gear, an operating rod, a rotating shaft and a rotating frame, wherein the power shaft penetrates through the first gear and is fixedly connected with the first gear; the operating rod penetrates through the second gear and is fixedly connected with the second gear; the rotating frame is provided with a containing space for containing at least one part of the operating rod and can drive the operating rod and the second gear to rotate around the rotating shaft between a first position and a second position; the operating rod is parallel to the power shaft when at the first position; the first gear and the second gear are meshed with each other when the operating rod is at the second position. The drilling and milling tool can be inserted into a narrow incision of a patient to facilitate surgical operation.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a multi-angle drilling and milling tool for minimally invasive surgery. Background technique [0002] Minimally invasive surgery has the advantages of small trauma area, fast postoperative recovery, and low surgical cost. It has become a development trend of clinical surgery. [0003] In order to facilitate the minimally invasive surgical tool to be inserted into the narrow (for example 3 mm-15 mm) incision of the patient for surgical operation, the cutting knife or the drilling and milling head in the minimally invasive surgical tool of the prior art is elongated straight rod shape, but this This minimally invasive surgical tool does not effectively cut and drill the bony surface perpendicular to the skin of the incision (such as the posterior side of the patella). The free end of the cutting knife or drill bit of the minimally invasive surgical tool should be curved in order...
