Abstract
The present disclosure illustrates an osteotome for treating hard tissue. The osteotome embodiments described herein include a shaft with a working end configured to displace hard tissue and a lumen to deliver material through the shaft. The working end may create pathways by selectively transitioning from a linear to a non-linear configuration. The lumen may deliver material through the shaft while the working end is in a linear or a non-linear configuration allowing precise filling of the pathways.
Claims20
A medical device for treating hard tissue, comprising:
- a conduit having a series of slots along a first side of an articulating distal portion of the conduit;
- a rod extending through the conduit, the rod including a flexible portion;
- a handle including an actuating portion coupled to a proximal end of the rod, wherein movement of the actuating portion results in an associated movement of the rod and the conduit to selectively move the articulating distal portion between a linear configuration and an articulated configuration;
- and a side port coupled to the handle with an insertion guide that extends to an accessible portion of the conduit extending along the conduit to a distal end of the conduit;
- further comprising a lumen inserted in the insertion guide and extending through the conduit, wherein the lumen is semicylindrical, and wherein the semicylindrical flexible portion of the rod and the lumen are positioned within the conduit to form a cylinder that fills the conduit.
A medical device for treating hard tissue within a vertebra of a patient, the medical device comprising:
- a shaft having an articulating portion, the shaft comprising:
- a hollow conduit with a series of slots along a first side to permit deflection, and
- a semicylindrical rod extending through the hollow conduit and contiguous with the first side of the hollow conduit,
- wherein the hollow conduit and semicylindrical rod are coupled at a distal end of the articulating portion such that a force applied along an axis of the semicylindrical rod translates to a deflection in the articulating portion to move reversibly between a linear configuration and an articulated configuration, where the series of slots and the semicylindrical rod limit movement between the linear configuration and the articulated configuration to a single plane;
- a side port with a clip holster that extends to an accessible portion of the shaft extending along the hollow conduit to a distal end of the conduit;
- and
- a lumen having a clip to selectively secure the lumen to an insertion guide, the lumen extending through the hollow conduit with openings at both ends to permit movement of material through the shaft without being in contact with the shaft.
