Publication number: 20220000493Abstract: An endplate processor, comprising a grip portion (1), a handle (2), and a treating head (3). The treating head (3) and the grip portion (1) are fixed at both ends of the handle (2), respectively. A semicircular groove (4) is formed on an end face of the end of the treating head (3) away from the handle (2). The semicircular groove (4) forms a bowl-shaped cavity at the tip of the treating head (3). The bowl-shaped structure is suitable for scraping an endplate (20) in the intervertebral space that is wide at the center and narrow at the periphery. Since the volume of the scraping structure is small, the endplate processor can freely move in the intervertebral space, increasing operation convenience. Since the distal end of the endplate processor is blunt due to the bowl shape, it is even harder to penetrate through the aorta deep in the contralateral annulus, increasing the surgical safety.Type: ApplicationFiled: November 5, 2018Publication date: January 6, 2022Inventors: Zongde YANG, Zhicai SHI

Publication number: 20220000495Abstract: A guiding device can include a guide including a through hole for insertion of an ultrasound probe that forms a tunnel to a bone. The guide can be configured to guide movement of the ultrasound probe inserted through the through hole; an offset portion offset from an axis of the through hole. The guiding device can also include an offset portion with an abutment portion configured to abut to an outer wall of the bone, on a side on which the through hole is located, in a direction orthogonal to the axis and a bone-tunnel introduction portion provided on an opposite side to the side on which the through hole is located and being configured to be inserted into the tunnel. The bone-tunnel introduction portion can have a sectional polygon shape smaller than a polygon on an inner circumferential face of the through hole.Type: ApplicationFiled: September 22, 2021Publication date: January 6, 2022Applicant: OLYMPUS CORPORATIONInventors: Yasuyuki MATSUMURA, Takamitsu SAKAMOTO, Ken FUJISAKI
