HARVESTING CANCELLOUS BONE AND MARROW FROM DISTAL FEMUR, PROXIMAL TIBIA, DISTAL TIBIA, OR CALCANEUS USING BONE PRESS APPARATUS
20230139232 · 2023-05-04 ·

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.

The present disclosure includes apparatuses for a bone graft harvesting device. An example apparatus includes a blade tip including a proximal end and a distal end, wherein the distal end of the blade tip includes a number of blades configured to morcellate bone in response to being rotated and a lead tip located within the blade tip and configured to maintain the bone graft harvesting apparatus centered on a bone graft punch hole.

Process for creating bone cavities for bone healing
09839531 · 2017-12-12 · ·

A process and system for performing orthopedic surgery to create a series of channels with a subject's bone to allow a reduced pressure system to be applied directly to the bone-implant interface to enhance bone healing is provided. The process for to promote healing of a bone of a subject includes creating a three-dimensional model of the bone; preoperatively planning a location of an implant relative to the model; creating a plan for the location of precision channels that reach the bone-implant interface based on the model and the implant; resurfacing the bone to fit the implant into or onto the bone based on the preoperative plan; and milling the precision channels into the bone in the location to promote healing of the bone and/or bone implant interface; and applying a pressure reduction system at the bone-implant interface to promote bone healing.

Bone Preparation Device
20220047403 · 2022-02-17 · ·

n assembly for preparing bone stock includes a shell (52) comprising a base (54) having a support surface (56), and a lid (58). The base and lid have a void space (60) therebetween. A carriage (62) is disposed at least partially within the void space, and moveable across the support surface. The carriage comprises a wall (64), at least a portion (65) of which is resiliently deformable. The wall cooperates with the base to define a preparation chamber (66), and a removal element (68) configured to remove soft tissue from the bone stock is disposed at least partially therein. The resilient portion of the wall is configured to deform when bone stock is positioned between the removal element and the wall. The carriage is configured to receive power from a drive train to actuate movement of the carriage across the support surface, and the removal element is also configured to receive power from the drive train.

Apparatus for osteotomy and graft preparation
09775629 · 2017-10-03 · ·

Surgical tools that increase surgical accuracy for orthopedic procedures involving long bone osteotomy with or without supplementation with allograft or autograft. Two clamps on the operative side are rigidly interconnected to one another with an adjustable rod that is locked into place, preserving length and rotation of the bone. A graft preparation device is used on the operative table. It enables alignment of the graft to preserve the desired mechanical and anatomic axes and to provide rigid fixation of the graft for cutting. Adjustable jigs ensure exact cuts.

System for processing bone stock including a bone cleaning head, a bone milling head and base that powers both the cleaning head and the milling head

A system for cleaning bone that includes a base unit with a motor, a cleaning head with a cleaning element and a mill head with a mill element. Both the cleaning head and the mill head are designed to be coupled to the base unit. Both the cleaning element and mill element have features that facilitate their coupling to the motor. When the cleaning head is attached to the base unit, a motor in the base unit rotates the cleaning element to remove soft tissue from the bone so as to clean the bone. The mill element is placed on the base unit and the cleaned bone placed in the mill head. The actuation of the base unit motor results in the actuations of the mill element. The actuation of the mill element converts the cleaned bone into bone chips.

Meniscal transplant system
11452622 · 2022-09-27 · ·

A workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.

In one embodiment, the biological disc graft is useful for treating any joint pain. The invention also provides a method of implanting said biological disc graft in a way that is minimally invasive and less dangerous.

Harvesting cancellous bone and marrow from intramedullary canal formed in medullary cavity using bone press apparatus

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.
