Abstract
Medical devices for creating or expanding a cavity within bone of a patient are disclosed. In some circumstances, a medical device, such as an osteotome is designed to facilitate simultaneous advancement and articulation of a distal portion of the osteotome. Simultaneous advancement and articulation of the distal portion may reduce one or more forces on the distal portion of the osteotome relative to other methods in which advancement and articulation are separated in time, thereby decreasing the risk of breakage or other damage to the osteotome.
Claims20
A method of manipulating an osteotome, the method comprising:
- obtaining an osteotome, the osteotome comprising a housing and a first shaft that is threadably coupled to the housing;
- inserting a distal portion of the osteotome into bone of a patient;
- and
- rotating the first shaft of the osteotome relative to the housing in a first direction;
- wherein rotation of the first shaft relative to the housing causes both (1) axial displacement of the distal portion of the osteotome relative to the housing and (2) lateral displacement of a distal tip of the osteotome relative to a longitudinal axis of the osteotome.
A method of creating a cavity within bone of a patient, comprising:
- obtaining an osteotome;
- inserting a distal portion of the osteotome into the bone of the patient;
- and
- rotating a first shaft of the osteotome relative to a housing in a first direction;
- wherein rotation of the first shaft relative to the housing causes both (1) axial displacement of the distal portion of the osteotome relative to the housing and (2) lateral displacement of a distal tip of the osteotome relative to a longitudinal axis of the osteotome to create the cavity within the bone of the patient.
A method of axially displacing and bending a distal portion of an osteotome, comprising:
- obtaining an osteotome;
- and
- rotating a first shaft of the osteotome relative to a housing;
- wherein rotation of the first shaft relative to the housing causes both (1) axial displacement of a distal portion of the osteotome relative to the housing and (2) lateral displacement of a distal tip of the osteotome relative to a longitudinal axis of the osteotome.
