Example 1

fig. 2 is a structural view of the muscle stretching sheet of the present invention.

In this embodiment, as shown in fig. 1 and 2, the present embodiment provides a cervical vertebrae retracting tool, which includes: two sliding rods 101, two muscle opening pieces 3, an upper sliding piece and a lower sliding piece which are horizontally arranged; wherein the upper and lower sliding sheets slide along the sliding bar 101 back to form an operation window; after the operation window is formed, the two muscle stretching pieces 3 hook the corresponding sliding rods 101 respectively, and the two muscle stretching pieces 3 are pulled to make the muscles stretch out towards the outer sides of the sliding rods 101 so as to adjust the size of the window of the operation window.

In the embodiment, the muscles are spread to the outer side of the sliding rod through the two muscle spreading pieces and are fixed through the sliding rod and the upper and lower sliding pieces, so that the functions of keeping the muscles from being folded and adjusting the size of the operation window after the cervical vertebra is retracted are realized.

In this embodiment, referring to fig. 2, the hooks of the two muscle-stretching pieces 3 hook the sliding rod 101 to keep the muscles in the non-closed state, and the distance between the two muscle-stretching pieces 3 is controlled by controlling the holding portions of the two muscle-stretching pieces 3 to apply pressure along the directions a and b, respectively, so as to adjust the size of the window of the surgical window.

Fig. 3 is a structural view of the positioning screw of the present invention.

In order to fix the upper and lower sliding plates to the vertebral body for easy manipulation, as shown in fig. 3, the cervical vertebrae retracting tool comprises: two set screws 4; the upper and lower sliding sheets are both provided with a positioning hole 203, and the two positioning screws 4 are suitable for being respectively inserted into the corresponding positioning holes 203 to be fixed on the vertebral body.

In the present embodiment, as shown in fig. 1, the upper slider piece 201 is movable on the slider bar 1, and the lower slider piece 202 is movable on the slider bar 1.

In this embodiment, as shown in fig. 3, the tip of the set screw 4 can be inserted into the positioning hole 203 and fixed on the vertebral body.

In the present embodiment, in order to hook the sliding rod of the sliding rod, as an alternative embodiment, the muscle-stretching piece 3 is provided in a J shape, and the lower end of the muscle-stretching piece hooks the sliding rod 101 to form an expanding fulcrum.

To sum up, the utility model discloses a two muscle are propped open the piece and are dialled the muscle to the slide bar outside to fix through slide bar and upper and lower slide piece, realized keeping the function that the muscle did not fold and adjust the operation window size after the cervical vertebra is led out.
