A system for harvesting bone material from a bone may include a rotary cutter defining a rotary cutter longitudinal axis extending between a rotary cutter proximal end and a rotary cutter distal end. The rotary cutter may have a drive shaft configured to receive input torque, and an osteochondral cutter configured to cut the tissue and receive the tissue material in response to rotation of the osteochondral cutter under pressure against the tissue. The system may further include a bone port defining a bone port longitudinal axis extending between a bone port proximal end and a bone port distal end. The bone port may have a bone port cannulation sized to closely fit over the osteochondral cutter. At least one of the bone port proximal end and the bone port distal end may be securable to the tissue. A stratiform tissue graft may be delivered through the bone port.

Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

This document describes bone matter collection devices and methods for their use. For example, longitudinally extendable/retractable spirally wound, conically-shaped bone matter collection/harvesting devices are described. In some implementations, such bone matter collection devices can be attachable with and detachable from bone drill bits. In some implementations, bone chips generated by bone drilling are collected in such a bone matter collection device while the bone matter collection device is detachably coupled to the bone drill bit, and the collected bone chips can be used for bone grafting and other purposes.

The invention involves a device and method for acquiring bone marrow aspirate. The system includes an elongated cannulated fastener having a threaded end for attachment to a bone. The threaded portion includes a directional aperture sized to allow marrow to be drawn into the cannula. The directional aperture also allows the user to direct the aperture in a desired direction within the bone for acquisition of the marrow. The distal end of the cannulated fastener includes a connector which may be in the form of a Luer lock to allow vacuum to be applied to the cannula for drawing the marrow into a syringe or the like.

A bone graft delivery system can include an elongate tube and a handle having a trigger and a ratcheting mechanism. The trigger is actuated to deliver bone graft material through the tube. The bone graft delivery system can further include a distal tip at a distal end of the tube. The tip has one or more openings to deliver the bone graft material to a desired location and includes a surface suitable to act as a rasp for decorticating bone. A method for delivering bone graft material to a desired surgical location includes providing a bone graft delivery device, positioning the device adjacent the surgical location, decorticating bone, and delivering bone graft material to the surgical location.

A sacroiliac joint screw has a screw body having a head and a treaded shank with a self-drilling cutting tip. The screw body is cannulated and configured to receive a Steinmann pin for the purpose of a minimally invasive approach (MIS) for delivery to the sacroiliac joint (SI) while minimizing soft tissue damage. The self-drilling cutting tip creates a pilot hole. The threaded shank has a plurality of spiral cutting flutes, the spiral cutting flutes extend along a length of the threaded shank and are configured to provide a constant self-tapping feature. A plurality of bone harvesting windows are positioned in the spiral cutting flutes and are configured to pull in bone as the screw is advanced into the joint.

The invention resides in the field of medical technology. It relates in particular to a sonotrode suitable for use with an ultrasonic surgical instrument. The invention refers further to an ultrasonic surgical instrument for cutting or punching bones, including such a sonotrode as well as a method for manufacturing the sonotrode of the invention.

A bone screw and method of using the same for immobilizing a joint, the bone screw including a screw head, an elongate shaft having a threaded outer wall and a helically-shaped slot extending through the outer wall and longitudinally along the shaft. The slot extends longitudinally along a middle section of the threaded outer wall, terminating short of the proximal and distal ends of the shaft, or the slot extends through the distal end and/or to the proximal end of the shaft immediately adjacent to the screw head. The slot includes a cutting edge that is arranged to engage bone when the screw advances therethrough for cutting away a portion of the bone. A reservoir is located within the elongate shaft for collecting bone that is cut away or removed by the cutting edge.

A tissue collection and processing system for collecting bone fragments and tissue aspirated from a bone. The tissue collection and processing system includes a collection vessel, a collection vessel cap, a processing cover, a first tubing and a fluid withdrawal mechanism. The collection vessel has an opening formed therein to receive bone fragments and tissue aspirated from the bone. The collection vessel cap is capable of engaging the collection vessel to substantially seal the opening. The collection vessel cap or the collection vessel has a first port. The processing cover has an upper surface and a lower surface. The processing cover has a connection port and a bore. The connection port is proximate the upper surface. The bore is fluidly connected to the connection port and extends toward the lower surface. The processing cover has a density that is less than a density of fluid in the aspirated bone fragments and tissue. The fluid withdrawal mechanism is fluidly connected to the connection port with the first tubing to withdraw the fluid from the collection vessel. As fluid is withdrawn from the collection vessel, the processing cover is slidable in the collection vessel.
