Embodiment 1

[0107] Example 1, such as Figure 7 As shown in the present invention, in an adjustable channel device for cervical spine surgery, the substrates 1131 of the first auxiliary adjustment arm 113 and the second auxiliary adjustment arm 116 and the main adjustment arm 14 are rectangular.

[0108] In the first embodiment, the base plate 1131 of the first auxiliary adjustment arm 113 and the second auxiliary adjustment arm 116 and the main adjustment arm 14 are all rectangular, and the expanded operation channel 2 is cylindrical.

Embodiment 2

[0109] Example 2, such as figure 1As shown in the present invention, in an adjustable channel device for cervical spine surgery, the base plates 1131 of the first auxiliary adjustment arm 113 and the second auxiliary adjustment arm 116 and the main adjustment arm 14 are arc-shaped.

[0110] In the second embodiment, the base plate 1131 of the first auxiliary adjustment arm 113 and the second auxiliary adjustment arm 116 and the main adjustment arm 14 are arc-shaped, which can ensure that the expansion range is larger than the space in the first embodiment; wherein, the auxiliary adjustment arm The arc of the base plate 1131 of the first adjusting arm 113 and the second auxiliary adjusting arm 116 and the main adjusting arm 14 is 20-30 degrees.

[0111] Such as Figure 5 and Figure 6 As shown in the present invention, an adjustable cervical spine operation gap expansion channel device, the gap blocking assembly 3 includes a blocking piece 31 and a blocking piece 2 32;

Abstract

The invention discloses an adjustable cervical vertebra operation gap expansion channel device which comprises an expander body composed of a first expansion assembly, a second expansion assembly and a control assembly; The control assembly is arranged on the side, close to the holding end, of the second long extension arm and clamped to the main adjusting arm to be used for controlling position adjustment between the first expansion arm and the second expansion arm. a gap blocking assembly which is detachably clamped on the first auxiliary adjusting arm and the second auxiliary adjusting arm between the first expansion assembly and the second expansion assembly. According to the adjustable cervical vertebra operation gap expansion channel device, by arranging the expander body and the gap blocking assembly, the size of the expansion channel can be adjusted, and the purpose of increasing the expansion range in a limited mode is achieved; meanwhile, the gap blocking assembly is arranged to make up gaps generated by expansion during expansion, and the integrity of the expansion channel is guaranteed; the surgical field is effectively exposed so that a surgeon can smoothly finish the surgery.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an adjustable channel device for expanding the gap in cervical spine surgery. Background technique [0002] In cervical spine surgery, it is often necessary to incise the patient's skin in order to perform surgical treatment of the deep cervical spine. However, during the operation, both the affected skin and internal muscles will bring difficulties to the operation, and the contraction of the affected skin and internal muscles will affect the operation. obstruction of vision; [0003] In response to this problem, a series of devices for expanding the surgical channel during cervical spine surgery have been developed on the market, but most of the products on the market today are simple tubular devices, which are directly fixed on both sides of the cervical spine to connect the skin and subcutaneous muscle tissue. Separated to the sides to facilitate the doctor's ope...
