Patent number: 11786273Abstract: A surgical connection device for a spine is disclosed including a stabilization member, compression arms and traction arms, the device being used in conjunction with first anchor points fixed to vertebrae at a first lateral side of the spine and second anchor points fixed to vertebrae at a second lateral side of the spine. A first spinal rod may be attached to the first anchor points and a second spinal rod may be attached to the second anchor points. The compression arms connect the stabilization member to the first and second anchor points or rods and bear compressive forces. The traction arms connect the stabilization member to the first and o second anchor points or rods and bear tensile forces. Application of both tensile and compressive forces via the device may serve to straighten, change a direction of bending or increase a degree of bending of the rods and/or spine. The use of the traction arms may also provide for a more flexible construct.Type: GrantFiled: December 31, 2020Date of Patent: October 17, 2023Assignee: SPINAL DEVELOPMENTS PTY LTD.Inventors: Gregory James Roger, Davor Saravanja

Patent number: 11737833Abstract: The present disclosure relates to polyaxial bone screws and methods that enable the positioning of the polyaxial bone screws to be reliably determined using a surgical navigation system including a navigation probe. In an embodiment, a polyaxial bone screw comprises a threaded shaft inserted in bone and a head connected to the shaft, the head being rotatable relative to the shaft about a centre of rotation of the head of the bone screw. The position of a navigation probe is monitored using a navigation device. A first mating surface of the head of the bone screw is engaged with a second mating surface of the navigation probe; and the location of the centre of rotation of the head of the bone screw is determined based on the monitored position of the navigation probe when the first mating surface and the second mating surface are engaged.Type: GrantFiled: December 3, 2020Date of Patent: August 29, 2023Assignee: SPINAL DEVELOPMENTS PTY LTDInventors: Gregory James Roger, Davor Drago Saravanja

Publication number: 20230241317Abstract: The present disclosure relates to a syringe including a container, for containing a primary fluid, and at least one secondary fluid chamber configured to contain a secondary fluid. The container comprises a proximal end and a distal end and having a distal end opening at the distal end. The syringe further comprises a stopper, movably arranged within the container; and a plunger engageable with the stopper and configured to apply a force to the stopper to move the stopper within the container towards the distal end of the container, to expel primary fluid from the container through the distal end opening. The plunger is further configured to expel secondary fluid from the at least one secondary fluid chamber towards the distal end opening, to expel at least a portion of a residual volume of primary fluid through the distal end opening. A plunger system and assembly for a syringe and methods of expelling fluid from a syringe are also disclosed.Type: ApplicationFiled: September 30, 2022Publication date: August 3, 2023Inventors: Brett Hoe Slater, Gregory James Roger

Publication number: 20230200914Abstract: A system for aiding surgery on a patient is described including a display device and a storage device that stores an image of at least a portion of the anatomy of the patient, including one or more surgical navigation markers positioned on the patient, for display on the display device. An analyser is adapted to receive positional data of a probe based on positioning of the probe relative to the one or more markers on the patient. Based on the positional data, the analyser outputs correctional data to adjust an alignment of the image on the display device to match locations of said one or more markers.Type: ApplicationFiled: December 27, 2022Publication date: June 29, 2023Inventors: Gregory James Roger, Davor Saravanja
