Abstract
Disclosed are devices and methods for creating a bore in bone. The devices and methods described involve driving a rotating bit in an axial direction such that both rotation and linear movement are controlled and measurable. The instrument is useful for a surgeon to control and simultaneously measure the travel of the tool into the bone and prevent injury to surrounding structures.
Claims17
A medical drilling device comprising:
- a housing comprising:
- a hand-held portion;
- an engagement portion;
- and
- an actuator;
- an axial drive element extending through the housing between a proximal end of the housing and a distal end of the housing;
- a first drive element coupled to the axial drive element;
- a rotational drive element extending through the housing between the proximal and distal ends;
- a second drive element coupled to the rotational drive element;
- a coupler interchangeably connected to a working tool and the rotational drive element, wherein the coupler extends beyond the engagement portion of the housing;
- a first sensor comprising a transducer interfaced to the axial drive element, the transducer configured to measure a depth of the working tool into a bore, the transducer configured to output a first signal representative of advancement of the working tool relative to the distal end of the housing, wherein the first sensor measures a distance of the advancement of the working tool beyond the distal end of the housing;
- and
- an electronics package in electronic communication with the transducer, the electronics package including a second sensor configured to output a second signal representative of passage of the working tool through layers of tissue having differences in material strength.
