Definitions
- the present invention relates to a surgical screw and a fusion device using the same, and more particularly to a surgical screw capable of self-locking (self-locking) and a fusion device using the same.
- bone screws are commonly used to attach plates, rods, and the like, to one or more vertebrae, of implants and instruments.
- US Patent US7846207 discloses a technique for inserting a cage between the vertebrae and mounting the bone screw to the vertebrae to fix the cage.
- a safety screw securing screw
- US Pat. No. 7,762,379 discloses a method for preventing loosening of a bone screw in a SI joint fusion implant used when a joint between the sacrum (Sacrum) and the iliac (pelvis, Iliac) is problematic. Nuts are used.
- Patent Document 1 US Patent US7846207
- Patent Document 2 US Patent US6398783
- Patent Document 3 US Patent US7625379
- An object of the present invention devised to solve the above problems, and relates to a surgical screw capable of self-locking (secure-locking) without a separate locking mechanism and a fusion device using the same.
- the main body screw is formed on the outer circumferential surface, the main body screw and the offset spaced apart between the main body locking screw is formed, the screw body formed with a main body driving groove on the top; And a sleeve screw threaded to the main body locking screw on an inner circumferential surface thereof, and a sleeve having a sleeve stopper formed to be spaced below the sleeve screw to support the main body locking screw.
- the lower side of the sleeve stopper is characterized in that it has an inner peripheral surface coinciding with the outer peripheral surface of the offset.
- the main body locking screw has the same pitch and outer diameter as the main body screw, and the offset has the length of an integral multiple of the pitch of the main body screw.
- the lead height of the main body locking screw or the sleeve screw is less than 1 times the pitch of the main body locking screw.
- Another invention the above-described surgical screw; And a plate on which the surgical screw is mounted.
- Another invention the above-described surgical screw; And a cage having a through hole through which the surgical screw passes.
- FIG. 1 is a perspective view of a surgical screw according to an embodiment of the present invention.
- Figure 2 is an exploded perspective view of the surgical screw of Figure 1;
- FIG. 3 is a cross-sectional view of the loosened state of the surgical screw of FIG.
- FIG. 4 is a cross-sectional view of the locked state of the surgical screw of FIG.
- FIG. 6 is a cross-sectional view of the fusion device of FIG.
- An object of the present invention relates to a surgical screw capable of self-locking without a separate locking mechanism and a fusion device using the same.
- reference numeral 200 denotes a surgical screw according to an embodiment of the present invention.
- the surgical screw 200 basically includes a screw body 202 and a sleeve 204 fastened to the screw body 202.
- the screw main body 202 has a main body screw 206 formed on the outer circumferential surface thereof, and the main body locking screw 210 is formed by being spaced apart from the main body main screw 206 and the offset 208 therebetween.
- the main body locking screw 210 may have the same outer diameter as the main body screw 206 or may have a larger outer diameter.
- the main body locking screw 210 is the main body screw 206 so that the main body locking screw 210 and the main body screw 206 are simultaneously screwed together when the screw body 202 rotates. ) Has the same outer diameter.
- the offset 208 has a length that is an integer multiple of the pitch of the main body screw.
- the upper portion of the screw body 202 is formed with a main body driving groove 212 for receiving a rotational force from a mechanism such as a driver.
- the sleeve 204 is formed on the inner circumferential surface of the sleeve screw 216 to be mated with the body locking screw 210, is formed spaced apart from the lower portion of the sleeve screw 216 to support the body locking screw 210.
- Has a sleeve stopper 218 which may be.
- the sleeve screw 216 is screwed in only a small amount of rotation with the main body locking screw 210, and the sleeve screw 216 by moving the main body locking screw 210 immediately below the sleeve screw 216.
- the sleeve stopper 218 serves to prevent the main body locking screw 210 exiting to the lower side of the sleeve screw 216 to further advance downward.
- the overall height of the sleeve 204 can be reduced by not lengthening the engaging section of the sleeve screw 216 and the main body locking screw 210, and the sleeve screw 216 and the main body locking can be reduced. Due to the frictional force generated during the screwing of the screw 210 can reduce the burden of labor given to the operator.
- the lead height of the main body locking screw 210 or the sleeve screw 216 is preferably 1 times or less than the pitch of the main body locking screw 210.
- the lower side of the sleeve stopper 218 has an inner circumferential surface that coincides with the outer circumferential surface of the offset 208, so that the offset 208 is guided by the lower side of the sleeve stopper 218.
- the straightness of the screw body 202 can be secured with respect to the sleeve 204.
- the sleeve body 214 of the sleeve 204 may be formed in various shapes as needed, and when the outer side is spherical, it is possible to rotate in the plate, cage, and the like.
- the fusion device 220 includes a cage 222 inserted between the vertebrae and a surgical screw 200 inserted into the through hole 224 formed in the cage 222. Since the surgical screw 200 is mounted with a sleeve 126 having a sleeve body 214 whose outer surface is curved, the surgical screw 200 can rotate in a predetermined range within the through hole 224. Since the surgical screw 200 is screwed to the vertebral body while being self-locked to the cage 222, an additional locking device is not required.
- the fusion device 226 includes a plate 228 contacting a bone such as a vertebra and a surgical screw 200 installed on the plate 228. Therefore, since the surgical screw 200 is seated on the plate 228 is self-locking, there is an advantage that no additional locking device is required. Since the surgical screw 200 has a sleeve 126 having a sleeve body 214 whose outer surface is curved, the surgical screw 200 is rotatable in a predetermined range with respect to the plate 228.
