Publication number: 20240225709Abstract: The disclosure provides an osteotomy tool, namely an opening wedge tap Instrument, for prying open an osteotomy cut to a pre-determined degree to correct a tibia deformity. The osteotomy tool includes a screw and a shank. The screw and shank have a through-hole aligned along the osteotomy tool's longitudinal axis to form a passage for receiving a guidewire, which helps to position and guide the osteotomy tool's movement. While the osteotomy tool moves into the osteotomy cut, the osteotomy tool pries open the ostomy cut. The disclosure also provides a method for performing an osteotomy using the osteotomy tool. The method includes performing an osteotomy cut on a tibia, mounting a guidewire into the osteotomy cut, inserting the guidewire into the opening wedge tap instrument's through-hole, screwing the opening wedge tap instrument into the osteotomy cut to pry open the osteotomy cut to a degree for correcting the tibia deformity.Type: ApplicationFiled: June 12, 2023Publication date: July 11, 2024Inventors: Khay Yong SAW, Caroline Siew Yoke JEE

Patent number: 11744570Abstract: The disclosure provides a patella joystick for tilting a knee cap in an operation of knee arthroscopy and a method of using the patella joystick. The patella joystick can include a handle, a shank, a tapered portion, and a screw portion. The tapered portion has a diminishing diameter and provides a structural transition between the shank and the screw portion. The screw portion can include a thread and a screw point. The thread can have a buttress form, and the screw point can have an inverted cone shape with a cone angle of at or about 90°. The method of using the patella joystick can include: drilling a pilot hole into the patella; screwing the patella joystick onto the pilot hole; and holding the patella joystick to tilt and/or lift the knee cap.Type: GrantFiled: March 5, 2021Date of Patent: September 5, 2023Inventors: Khay Yong Saw, Reza Ching Soong Ng, Caroline Siew Yoke Jee

Patent number: 9486228Abstract: Surgical devices, kits and methods of using thereof are described. Generally, the surgical kit includes an osteotomy guide device and/or a bone spacer guide device. The surgical kit can be used in a surgical method for correcting a malalignment of the knee joint that involves performing a fibular osteotomy and/or a tibial osteotomy, and/or administering stem cells. Generally, the osteotomy guide device is configured to allow drilling to occur around the tibia and across a horizontal cross-sectional plane of the tibia so that a direction of each of the drill holes that are formed in the tibia is substantially parallel to or on the same horizontal cross-sectional plane of the tibia. The osteotomy guide device allows drilling to be conducted efficiently and accurately.Type: GrantFiled: October 7, 2013Date of Patent: November 8, 2016Assignee: KLSMC STEM CELLS SDN BHDInventors: Khay Yong Saw, Reza Ching Soong Ng, Caroline Siew Yoke Jee
