Abstract

The invention discloses a cold light source vertebral plate drag hook used during lumbar surgery. The cold light source vertebral plate drag hook consists of a hook protrusion, a drag hook body, a light source lens pipe, a handle, a fixed hook and a connector, wherein the handle is a hollow cavity; a smooth operation rod is arranged in the axial direction of the handle; the handle is downwards bent at 90 degrees along the tail end of the axial position of the handle to extend; the bent and extending part is the drag hook body; the tail end of the drag hook body is inwards retracted to form a hook shape, namely the hook protrusion; the light source lens pipe is arranged in the hollow cavity of the handle in a sleeving way; the light source lens pipe is downwards bent along the axial position of the handle to be exposed and tightly adhered to the drag hook body; the other end of the light source lens pipe is axially exposed; the connector is arranged at the exposed end of the light source lens pipe; the fixed hook which is downwards inclined is arranged at one end of the axial position of the handle.

Description

The cold light source laminectomy retractor used during a kind of lumbar surgery

Technical field:

The present invention relates to a kind of cold light source laminectomy retractor, use when being specially adapted to lumbar surgery.

Background technology:

During current lumbar surgery, cut skin, with orthopaedics common laminectomy retractor, muscle is pulled open, strut to greatest extent and eliminate tissue outstanding on intervertebral disc with curet and rongeur.This technology belongs to open operation, operation wound is large, and risk that is hemorrhage or that infect occurs comparatively large in operation, the chance of Post operation generation complication is more, and the hospital stays is long, increases patient's financial burden.

Summary of the invention:

Task of the present invention is that to propose a kind of wound little, easy and simple to handle, the cold light source laminectomy retractor used during the good a kind of lumbar surgery of therapeutic effect.

Task of the present invention completes like this, the cold light source laminectomy retractor used during a kind of lumbar surgery, it is characterized in that: cold light source laminectomy retractor is by unciform process, drag hook body, luminous source mirror pipe, hands handle, fixation hook and union joint are formed, handle is a cavity, the axis of handle is smooth action bars, end along handle axial location is that 90o downward bending extends, bending extension is drag hook body, described drag hook body end shrinks in hook-shaped inwards for unciform process, luminous source mirror pipe is set with in described handle cavity, described luminous source mirror pipe exposes along handle axial location downward bending and is close on drag hook body, the luminous source mirror pipe other end axially exposes, this one end luminous source mirror pipe exposed is equipped with union joint, one end place of handle axial location has one to the fixation hook of lower outside slash.Got on the bus outer silk and optical fiber of described union joint spins.Cold light source laminectomy retractor is fixed on operation table side by fixation hook.Cold light source laminectomy retractor adopts titanium alloy material to make.

The present invention has following effect: the cold light source 1, on light source laminectomy retractor fully can be irradiated to the position, deep of operation, and what visual area was become is more clear.Instrumentation is also very flexible.2, traditional open surgery otch large (about about 5---10cm), paraspinal muscle excision many (postoperative occur denervation phenomenon), vertebrae plate resection many (postoperative easily occur lumbar vertebrae instability), intraoperative hemorrhage is many.And the application of cold light source laminectomy retractor can make traditional operation Wicresoft; This art formula skin incision is only 1.5cm, and only carries out reduced pressure treatment to pathological changes reduced pressure zone, can play a protective role to greatest extent to paraspinal muscle, vertebral plate.3, prevent scraper spoon portion from entering intervertebral disc in art excessively dark, effectively the generation of minimizing post-operative complication, this operation wound is little, risk is low, intraoperative blood loss amount few, and patient is acceptant.4, indication is also more extensive: all adapt to lumbar vertebra multi-segmental spinal canal stenosis, intervertebral disc prolapse (free, calcification, deviate from).And carry out the implantation etc. of Invasive lumbar fusion device under energy Wicresoft, play considerable advantage.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present invention; Fig. 2 is that Figure 1A-A locates enlarged diagram; Fig. 3 is that Figure 1B-B locates enlarged drawing; Fig. 4 is Fig. 1 C-C place structure for amplifying schematic diagram.

Drawing illustrates: 1, unciform process, 2, drag hook body, 3, luminous source mirror pipe, 4, handle, 5, fixation hook, 6, union joint.

Detailed description of the invention:

Embodiment is described in detail in conjunction with above accompanying drawing, as shown in Figure 1, cold light source laminectomy retractor is by unciform process 1, drag hook body 2, luminous source mirror pipe 3, handle 4, fixation hook 5 and union joint 6 are formed, described handle 4 is cavitys, the axis of handle is smooth action bars, end along handle axial location is that 90o downward bending extends, bending extension is drag hook body 2, described drag hook body end shrinks in hook-shaped inwards for unciform process 1, luminous source mirror pipe 3 is set with in described handle cavity, described luminous source mirror pipe exposes along handle axial location downward bending and is close on drag hook body, be beneficial to again optically focused directly to visit a patient stove, the luminous source mirror pipe other end exposes along the axis of handle, this one end luminous source mirror pipe exposed is equipped with union joint 6, got on the bus outer silk and optical fiber of described union joint spins, the gap place being set with luminous source mirror pipe in handle cavity can adopt sealant sealing, one end place of handle axial location has one to the fixation hook 5 of lower outside slash, as shown in Figure 4, cold light source laminectomy retractor adopts titanium alloy material to make.

During work, first cold light source laminectomy retractor is fixed on operation table side by fixation hook, easy to operate and use during operation.By " C " arc preoperative location diseased region during work.Then, the other stringer minimal incision * opening 0.5cm work one about 1.5cm between lesion segment sour jujube.Bone stripping (cobb) peels off paraspinal muscle to articular process along spinous process, puts into light source laminectomy retractor and retracts paraspinal muscle, and be fixed on articular process outer rim.Light source laminectomy retractor connecting fiber is on cold light source machine.Open cold light source machine, very clearly can appear diseased region, be equivalent to formation one service aisle clearly; manifest pathological changes vertebral plate clearly, can fully expand canalis spinalis and reduce pressure, remove ligamenta flava; appear and neuroprotective tissue, nucleus pulposus clamp extracts outstanding nucleus pulposus.Art finishes, and extract light source laminectomy retractor, skin closure one pin, this operation wound is little, risk is low.
