Abstract: A verification block structure and a verification system for orthopedic surgery are provided. The verification block structure includes a base and an artificial bone block. The base has a carrying portion and a bottom corresponding to the carrying portion. The artificial bone block is detachably fixed to the carrying portion of the base, and a shape or a material of the artificial bone block is determined upon a bone characteristic of a patient and/or a surgical method.

Abstract: A liquid-cooled cooling device with a channel includes a base a cover unit which is a cylindrical tube sleeved onto the surface of the base. The base has a surface which a groove is concavely disposed on, with a spoiler disposed on a portion of a wall of the groove and extending for a predetermined length in an axial direction of the groove. The cover unit covers the groove and thereby forms a channel which a liquid passes through, with the channel not completely closed by the spoiler. One of the base and the cover unit has a liquid inlet and a liquid outlet. The liquid inlet is in communication with one end of the channel. The liquid outlet is in communication with the other end of the channel.

Abstract: A liquid-cooled cooling device with a channel includes: a base having a surface which a slender groove is concavely disposed on, with a spoiler disposed on a portion of a wall of the groove and extending for a predetermined length in an axial direction of the groove; and a cover unit coveringly disposed at the base to cover the groove and thereby form a channel which a liquid passes through, with the channel not completely closed by the spoiler. One of the base and the cover unit has a liquid inlet and a liquid outlet. The liquid inlet is in communication with one end of the channel. The liquid outlet is in communication with the other end of the channel.

Abstract: A grinding device includes a grinding member disposed on a base, and a board rotatably supported in the base at a shaft. An axle is rotatably secured in the board for supporting the tools. A spring is coupled between the base and the board for moving the axle and thus the tools toward the grinding member and for allowing the tools to be ground by the grinding member. The grinding member is rotated to grind the tools. A rack is coupled to the axle to rotate the tools for allowing the peripheral portion of the tools to be ground by the grinding member.
