Little vertebral pulp pincers of looking light
Technical field
The present invention relates to a kind ofly look light vertebral pulp pincers for minimally invasive spine surgical little, under miniature incision, provide good surgical field of view, and easy to operate.
Background technology
Intervertebral disc prolapse often needs resection of nucleus pulposus.The conventional spinal posterior approach exists wound big, hemorrhage many, shortcomings such as corrective surgery fear, the long-term chronic pain of postoperative.In recent years, arthroscopic diagnosis has obtained fast development in the spinal column, and various endoscopies are applied to clinical.Under scope, can carry out and sting except the part sclerotin, extract operations such as intervertebral disc, ligamenta flava.
But still there are problems such as required otch is big, wound is bigger in present endoscope system owing to Inlet and outlet water irrigation channel, cold light source passage separately enter focus from different otch with operating apparatus.For this reason, we have designed this little vertebral pulp pincers of looking light.
Summary of the invention
The present invention adopts integrated design the vertebral pulp pincers with by little TV structure that the lightweight soft material is made, comprise Inlet and outlet water irrigation channel, light source optical fibers, photographic head and image pathway in little TV structure, not only can be clear in the mini-invasive incision downward view, and have light advantage such as easy to operate.
The present invention includes vertebral pulp binding clip, binding clip movable axis, connecting rod, bar sheath, go up lower handle, handle movable spring slice, articulated elements, little TV structure (including Inlet and outlet water passage, optical fibers, photographic head and image transmission channel) and external device composition.The power of lower handle passes to by the movable mechanical axis of binding clip by articulated elements and connecting rod, binding clip is opened or closure.Little TV structure directly is fixed on the pincers, is connected with external device at the pincers afterbody, and standard corresponding, directed location design one by one (as one protruding one recessed butt joint design) is adopted in both junctions, accomplishes seamless link.Cold light source interface on the external device, image transmission external tapping and intake-outlet connect external equipment respectively.
Vertebral pulp pincers are in the past compared, and the present invention possesses following characteristics.
1, little TV structure and caliper adopt integrated design, namely directly add TV structure in a subtle way on traditional vertebral pulp pincers.
2, comprising Inlet and outlet water irrigation channel, light source optical fibers, photographic head and image pathway in little TV structure can provide good surgical field of view for Minimally Invasive Surgery, simultaneously light, easy operating.
3, little TV structure is connected with external light source television system, bath, negative pressure suction system by the external device of standardized designs.
4, external device is provided with water flushing channel interface, negative pressure water absorption channel interface, light source interface and image defeated interface outward; Standard corresponding design one by one (as one protruding one recessed butt joint design) is adopted in external device the place ahead and little TV structure junction, and is simultaneously for convenience detach, is convenient to change different apparatuses.

The specific embodiment
External device (8) and the position disassembly, cleaning of vertebral pulp clamp main body are behind the autoclaving.External device front end and nested connection of little TV structure rear, both sides bath and suction interface (9) connect water inlet pipe and water outlet pipe respectively on the external device, and light source interface (10) and image output interface (11) are connected with light source, video image dendoscope system respectively.Open light source and television image system.Thumb and tiger district are positioned at the upper handle top, and four refer to as for the lower handle below.Four refer to by on push handle, after the binding clip closure, stretch into minim channel, through focus.Owing to have little TV structure on the vertebral pulp pincers, move with binding clip and mobile in the visual field, can be the patient the good visual field is provided.As the need flushing, open irrigation channel and wash.After confirming focus, decontrol four and refer to that binding clip is dehisced, dehiscing to aim at needs to extract vertebral pulp, on push handle and can sting and get vertebral pulp.
