Abstract
Description
technical field
[0001] The invention relates to a spinal minimally invasive operation system, in particular to a novel polymer material spinal minimally invasive expandable channel system. Background technique
[0002] Commonly used surgical instruments in existing spinal minimally invasive surgery systems include distraction sleeves, working sleeves, fixed arms, and spreader forceps. Generally, the function of distraction sleeves is limited to step-by-step insertion along the incision to expand the surgical work. However, it is difficult to judge whether the cannula has reached the surgical area after it is inserted into the body, and the outer end of the first placed distraction cannula has no suitable parts for grasping, which makes it inconvenient to insert the cannula; the working sleeve is fixed The columnar structure has a single structure, and in minimally invasive surgery, it is often necessary to expand the bottom of the target operation area, and the working sleev...
Examples
Embodiment Construction
[0028] Such as Figure 1-Figure 7 As shown, the novel polymer material spine minimally invasive expandable tunnel system of the present invention consists of a spreader sleeve 1, a working sleeve 2, a fixed arm 3 and an external light source.
[0029] Such as figure 1 As shown, the stretching sleeve 1 is used to place the incision of the target surgical part of the patient, and then insert the working sleeve 2 after stretching the surgical area. Starting from the bottom of the cone, color identification sections of different lengths are set, which are green 5cm, pink 1cm, yellow 1cm, and blue 3cm. The different color identification sections are different from the scale, so that the approximate range of insertion depth can be quickly determined, and it is easy to grasp the insertion depth. The rear end of the expansion sleeve 1 is provided with a plurality of anti-slip segments, which can effectively increase the convenience of use and facilitate the insertion of the expansion...
