Embodiment Construction
[0021] In order to enhance the understanding of the present invention, the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.
[0022] Such as Figure 1-5 As shown, the present invention is a unilateral dual-channel endoscopic orthopedic protector, comprising a sleeve 1, an observation portion 2 is arranged at the front end of the sleeve 1, and an upwardly tilted bone is arranged at the front end of the observation portion 2. The isolation plate 3 isolated from the nerve is transitionally connected between the isolation plate 3 and the observation part 2 through a corner portion 4, and the side surface of the end of the isolation plate 3 is a passivated rounded surface 5, which can reduce the impact on the nerve. For damage to human tissue, chamfered surfaces are provided between the side ...

The invention discloses an orthopedic protector capable of adopting a one-sided double-channel endoscope technology. The protector comprises a cannula, wherein the front end of the cannula is providedwith an observation part; the front end of the observation part is provided with an isolation board which is upwards unwrapped to separate bone substances from nerves; the isolation board and the observation part are in transition connection through a bent corner part; the side surface of the end part of the isolation board is a passivated rounded corner surface; an inner channel through which agrinding drill and a cutter bar pass is arranged in the cannula; and the outer side of the cannula is provided with scale marks. The protector has a simple structure, is reasonable in design and can prevent human body tissues from secondary injuries, meanwhile, surgery time can be shortened, and surgery risks are lowered.
Description
technical field [0001] The invention relates to the technical field of minimally invasive surgical instruments, in particular to a protector for unilateral double-channel endoscopic technology orthopedics. Background technique [0002] There are two commonly used techniques for the treatment of spinal diseases such as disc herniation, intervertebral stenosis, and intervertebral fusion, one is minimally invasive transforaminal endoscopy, and the other is traditional open surgery. The development of minimally invasive spinal endoscopic technology is becoming more and more mature, especially the transforaminal endoscopic technology is rapidly popularized nationwide. Foraminal endoscopic technology is a single channel, the scope of the operative field is affected, and the use of surgical instruments is limited. It has advantages in the treatment of intervertebral disc herniation, but it is more difficult in the treatment of other spinal diseases such as intervertebral stenosis. ...
