Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to a bone filling device. Background Art

[0002] Bone cement is the common name for bone adhesive, a medical material used in orthopedic surgery. It has such a popular name because some of its physical properties and its appearance and properties after solidification are quite similar to white cement used in construction and decoration. In the current medical field, in cases of vertebral compression fractures and other conditions, the vertebral height is lost and the stability of the spine is decreased due to the fracture. After bone cement is filled into the vertebral body, it can quickly restore part of the vertebral height, provide support for the vertebral body, and prevent further deformity. When using bone cement, a corresponding filling device is usually used to fill the cement to the designated position.

Then the staff turns on the first motor 273, and the first motor 273 will drive the two third bevel gears 272 through the long rod 271. The two third bevel gears 272 will respectively drive the first bevel gear 232 and the second bevel gear 263 to reciprocate, so that the first screw 231 and the second screw 262 reciprocate, so that the first screw 231 and the second bevel gear 263 respectively drive the cross lifting block 264 and the hollow lifting ring 233 to reciprocate. When the cross lifting block 264 is reciprocating, the vibration motor 265 will be turned on to generate vibration, so that the inner vibration cylinder 26 1 vibrates the bone cement inside the storage tank 210, and each time the hollow lifting ring 233 rises, the large gear 258 will roll on the outer surface of the rack 259, and the large gear 258 will accelerate the transmission pinion 256, and the pinion 256 will drive the inner rotating disk 2510 to rotate through the inner rotating rod 255, and the inner rotating disk 2510 drives the bevel gear plate 2511 to rotate through the right-angled trapezoidal block 2513, so that the bevel gear plate 2511 drives the conical gear ring 253 to drive the rotating ring 251 to rotate, and the rotating ring 251 will drive the ratchet gear ring 252 to rotate. When the ratchet gear ring 252 rotates, the rolling column 246 will roll on the slope of the outer surface of the ratchet gear ring 252, so that the steering rod 245 pulls the square movable rod 242 to compress the first The first spring 244 is used for the subsequent rolling column 246 to quickly rebound through the elastic force of the first spring 244, driving the ball 243 to knock the outer surface of the storage tank 210. Through the rotation of the ratchet gear ring 252, the ball 243 will repeatedly knock, so that the internal vibration of the vibration component 260 and the external knocking of the knocking component 240 can be conducive to the floating of bubbles in the bone cement, avoiding the subsequent injection of bubbles, making the prosthesis more compact, and improving the strength of the subsequent prosthesis. When the hollow lifting ring 233 descends, the large gear 258 will rotate in the opposite direction on the outer surface of the rack 259. At this time, since the ratchet gear ring 252 cannot rotate in the opposite direction, the inner turntable 2510 will idle inside the bevel gear plate 2511, and the right-angled trapezoidal block 2513 will be retracted into the inside of the mounting groove.After the vibration is completed, the valve 220 is opened, and then the piston rod 150 is pressed to drive the pressing plate 140 to descend, and the pressing plate 140 will press the bone cement into the filling tube 130 and inject it into the designated position.

[0049] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
