A bilateral humeral guide for intraosseous infusion includes a three-dimensional mirror symmetric shell configured to fit on either shoulder of a patient, the shell being symmetric about a plane bisecting an alignment hole configured to aid positioning of the shell on the shoulder by aligning the alignment hole on acromion of the shoulder, and two insertion-site indication holes symmetrically positioned on two opposite sides of the plane, the insertion-site indication holes including a left and a right hole each configured to indicate insertion sites for intraosseous infusion through the shell to a target region of a left or right humerus of the patient when the shell is positioned on the shoulder corresponding to the respective humerus.

Delivery systems and methods for delivering a material to a target site. A delivery instrument is coupled to a robotic manipulator and includes a delivery device with a distal tip having an opening to deliver the material to the target site. Controller(s) obtain a virtual model of the target site and a virtual boundary associated with the virtual model. The controller(s) register, using a navigation system, the virtual model and the virtual boundary to the target site and control the robotic manipulator to move the distal tip of the delivery device with respect to the target site. The controller(s) detect that distal tip of the delivery device either is, or will, interact with the virtual boundary, and in response, control the robotic manipulator to move the distal tip away from the virtual boundary.

A removable second stage biocompatible substrate filter including biocompatible implant material configured to trap second stage operative particulate matter, wherein the removable second stage biocompatible substrate filter is configured to combine with first stage operative particulate matter captured from irrigation fluid by a first stage filter, defining a combined product and the removable second stage biocompatible substrate filter is configured to be removable from a filter device container.

An irrigation system includes a housing on which a trigger is movably mounted, a motor, an accumulator, a pump and a gearing arranged inside the housing. At least the motor and the accumulator are mounted in a drive unit which can be replaced.

A bilateral humeral guide for intraosseous infusion includes a three-dimensional minor symmetric shell configured to fit on either shoulder of a patient, the shell being symmetric about a plane bisecting an alignment hole configured to aid positioning of the shell on the shoulder by aligning the alignment hole on acromion of the shoulder, and two insertion-site indication holes symmetrically positioned on two opposite sides of the plane, the insertion-site indication holes including a left and a right hole each configured to indicate insertion sites for intraosseous infusion through the shell to a target region of a left or right humerus of the patient when the shell is positioned on the shoulder corresponding to the respective humerus.

A delivery system and methods are disclosed for delivering a material to a target site. A delivery instrument is coupled to a robotic manipulator and comprises a delivery device having a distal tip comprising an opening deliver the material to the target site through the opening. A navigation system tracks the delivery device and the target site and generates position signals. One or more controllers are in communication with the robotic manipulator and the navigation system and define a virtual boundary associated with the target site, wherein the virtual boundary is utilized to constrain movement of the delivery device. The one or more controllers control one or more joint motors of the robotic manipulator to move the distal tip of the delivery device with respect to the virtual boundary based on the position signals from the navigation system.

A surgical collection assembly for filtering material from liquid obtained during surgery has a distal plunger plate that is used to compress collected material that is filtered from liquid and entrained materials gathered during surgery. The distal plunger plate needs to be maintained above the collection jar inlet during collection of the liquid and entrained material. This disclosure teaches several ways to reversibly retain the distal plunger plate above the collection jar inlet. Also taught is a drape clamp that can affix the assembly and related tubing to a drape.

The invention is related to the field of medical device, particularly to an intraosseous pressure release screw which not only excludes foreign matters but also facilitates intraosseous cleaning. The intraosseous pressure release screw comprises a screw rod with a central cavity disposed therein and a screw cap rotatably disposed on one end of the screw rod; the screw cap is provided with a pressure release part which communicates the central cavity with the outside; a rinsing opening is arranged on the rod section of the screw rod within the screw cap and is in communication with the central cavity; and a lockable opening is arranged on the side wall of the screw cap and can rotate with the screw cap to keep communication with the rinsing opening. As a screw cap with a pressure release part is arranged at the end of the screw rod, the food blockage of the screw rod can be prevented while the patient under treatment is eating, thereby ensuring the unobstructed pressure release. In the case of intraosseous cleaning, the screw cap is rotated to a position where the lockable opening is in communication with the rinsing opening; that is, the rinsing solution may be added to the central cavity via the rinsing opening, thus improving the therapeutic effect of core decompression.

An apparatus and method for external anteversion correction of an intact bone may include a first arcuate segment, a second arcuate segment rotatably coupled to the first arcuate segment, a first pin extending from the first arcuate segment to a proximal segment of the intact bone, a second pin extending from the second arcuate segment to a distal segment of the intact bone, and a control mechanism attached to the first and second arcuate segments. The control mechanism may rotate the first arcuate segment relative to the second arcuate segment to exert torsional force on the intact bone between the proximal and distal segments of the intact bone, thereby externally reducing anteversion of the intact bone.

A decompression device and method for removing marrow and other fluid from an intramedullary canal. The decompression device includes a cannula having a channel that allows fatty marrow to pass therethrough. A first port extends from the device and is in operable connection to a vacuum source that creates suction for removing fluid from the intramedullary canal. In some embodiments, one or more fenestrations are disposed along the second end of the cannula to expedite the removal of the fluid. In operation, the cannula is inserted into the intramedullary canal of a femur. Once fatty marrow is removed from the intramedullary canal, the cannula is removed and a reaming device is inserted into the femur. In this way, the fatty marrow is removed prior to the reaming procedure in order to prevent these fluids from traveling to the lungs causing blockage that leads to severe cardiorespiratory and vascular dysfunction.
