Claims (9)

  1. 1. An orthopedic support comprising a first portion configured to secure a first spinous process, a second portion configured to secure a second spinous process, and a third portion connected between the first portion and the second portion configured to support the first spinous process and the second spinous process, wherein the first portion and the second portion comprise two sub-portions at least on either side of the first spinous process and the second spinous process, respectively, wherein the third portion comprises two channels configured to secure the first portion and the second portion, wherein the channels open to a first surface and a second surface of the third portion, wherein ends of the channels have a width that is greater than a channel width of the other regions, wherein the channels are configured to receive foot-like structures at the ends of the first portion and the second portion and have a width that is greater than a width of the other regions of the first portion and the second portion, wherein one side of the channel end side walls, or the channel end side walls have a width that is greater than a width of the foot-like structures at the ends of the first portion and the second portion, wherein the channel end side walls have a corresponding tooth-like structure or the tooth-like structures.
  2. 2. The orthopedic support of claim 1, wherein the channel-up bottom surface comprises a tooth-like structure, the foot-like structures of the first and second portions respectively comprising protrusions or tooth-like structures for engaging the channel-up bottom surface tooth-like structure.
  3. 3. The orthopedic support of claim 2, wherein the tooth-like structures in the channels are each inclined toward the spine.
  4. 4. The orthopedic support of claim 1, comprising an elastic material, wherein the two sub-portions of the first and second portions are not closed to each other or the two sub-portions of the first and second portions are closed to or in contact with or engaged with each other.
  5. 5. The orthopedic support of claim 1 or 4, wherein the first and second portions comprise two symmetrically distributed sub-portions configured to contact both sides of the spinous process, and a distance between the two sub-portions tapers away from the third portion and in a direction along which the spinous process extends.
  6. 6. The orthopedic support of claim 1, wherein the third portion is a hollow structure.
  7. 7. The orthopedic support of claim 1, wherein the third portion of the spinous process support comprises a first surface configured to contact a first spinous process and a second surface configured to contact a second spinous process that is curved in an opposite direction.
  8. 8. The orthopedic support of claim 1, wherein a length of the first surface of the third portion of the spinous process support is greater than a length of the second surface as projected in a plane perpendicular to the plane of spinous process extension.
  9. 9. The orthopedic support of claim 1, further comprising a lamina support connected to the third portion of the spinous process support at an end proximal to the spine and extending in a direction away from the spinous process support.

Description

Orthopedics support piece Technical Field The invention relates to the field of orthopedics spines, in particular to an orthopedics support piece. Background The current surgical treatment scheme of lumbar degenerative diseases comprises traditional pedicle screw internal fixation fusion, non-fusion elastic fixation between spinous processes and the like. Although spinal fusion is the gold standard for lumbar surgical treatment, complications such as high incidence of degeneration of adjacent segments have attracted considerable attention. The interspinous process spreader is not perfect, and the problems of high risk of spinous process fracture, implant loosening and the like also occur successively. Disclosure of Invention The invention provides an orthopedic support, which aims at the technical problems existing in the prior art, and comprises a spinous process support, wherein the spinous process support comprises a first part, a second part and a third part, the first part is used for fixing a first spinous process, the second part is used for fixing a second spinous process, the third part is connected between the first part and the second part and is used for supporting the first spinous process and the second spinous process, and the first part or the second part respectively comprises two sub-parts which are positioned at two sides of the first spinous process or the second spinous process. In particular, the orthopedic support element, wherein the third portion comprises two channels therein configured to secure the first or second portion, the channels opening to the first or second surface of the third portion, wherein the width of the ends of the channels is greater than the channel width of the other regions, and wherein the width of the foot-like structures configured to receive the ends of the first or second portions is greater than the width of the other regions of the first or second portions. In particular, the orthopaedic support wherein one or both sides of the channel end side wall have a toothing, the respective sides of the foot of the first or second part comprising a protrusion or serration for engagement with the channel end side wall toothing, and/or wherein the channel-facing up bottom surface comprises a toothing, the respective bottom surface of the first or second part comprising a protrusion or serration for engagement with the channel-facing up bottom surface toothing. In particular, the orthopedic support wherein the toothed structures in the channels are each inclined toward the spine. In particular, the orthopedic support comprises an elastic material, wherein the two sub-portions of the first or second portion are not closed to each other or the two sub-portions of the first or second portion are closed to each other or are in contact or mesh. In particular, the orthopedic support, wherein the third portion is a hollow structure. In particular, the orthopedic support, wherein the first or second portion is configured as an elastic spinous process sleeve that wraps around the first or second spinous process. In particular, the orthopedic support, wherein the third portion of the spinous process support includes a first surface configured to contact a first spinous process and a second surface configured to contact a second spinous process that is curved in an opposite direction. In particular, the orthopedic support, wherein the length of the first surface of the third portion of the spinous process support is greater than the length of the second surface, as projected in a plane perpendicular to the plane of spinous process extension. In particular, the orthopedic support further comprises a lamina support connected to the third portion of the spinous process support at an end proximal to the spinal column and extending in a direction away from the spinous process support. The application can not only avoid the problem of high incidence complication caused by the traditional fusion operation, but also solve the problem of high risk of fracture of the spinous process caused by the non-fusion operation, and the like by supporting the vertebral lamina and the spinous process at the same time, can achieve the stability and controllability of the lumbar structure movement, simulate the original movement of the lumbar, ensure the dynamic movement of the spine and ensure the movement of the patient after operation to be more flexible.
