Problems solved by technology
For vertebral body fusion, fusion cages need to be implanted into the damaged intervertebral space. The fusion cages can be squeezed and deformed to support the vertebral bodies. However, most of the current fusion cages do not have the function of adjusting the fusion cages. It is inconvenient to install and operate, and cannot play a good supporting role

Embodiment Construction
[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention discloses a handle and an intervertebral operating system. The handle comprises a core rod, a middle sleeve and an outer sleeve; the core rod is sleeved with the middle sleeve; the middle sleeve is sleeved with the outer sleeve; the end of the middle sleeve is used for abutting against one end of a fusion cage; the core rod is used for penetrating through the fusion cage and being connected with the other end of the fusion cage; in the initial state, the outer sleeve is used for containing the fusion cage; and in the extrusion state, the middle sleeve is used for moving in the direction close to the fusion cage, and the outer sleeve is used for moving in the direction away from the fusion cage. According to the handle, along with the movement of the middle sleeve in the direction close to the fusion cage and the movement of the outer sleeve in the direction away from the fusion cage, the fusion cage is gradually disengaged from the outer sleeve, and the middle sleeve can extrude the fusion cage; and when the fusion cage is located in the outer sleeve, the fusion cage cannot deform due to limitation of the outer sleeve, the fusion cage can be deformed only after being separated from the outer sleeve, and the deformation quantity of the fusion cage can be controlled according to the moving distance of the middle sleeve, so that the fusion cage is more accurately controlled, and the operation is convenient.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a handle and an intervertebral operating system. Background technique [0002] With the aging of the population, spinal degenerative diseases with neck and shoulder pain and low back pain as the main symptoms are seriously affecting people's work and life. Intervertebral body fusion is one of the main methods for the treatment of spinal degenerative diseases. For vertebral body fusion, fusion cages need to be implanted into the damaged intervertebral space. The fusion cages can be squeezed and deformed to support the vertebral bodies. However, most of the current fusion cages do not have the function of adjusting the fusion cages. It is inconvenient to install and operate, and cannot play a supporting role well. Contents of the invention [0003] Based on this, the present invention overcomes the defects of the prior art and provides a conveniently operated handle...
