Description
Technical field
The invention belongs to clinical medicine domain, be specifically related to a kind of non-endoscope nucleus pulposus excision puncture needle for treating lumbar disc herniation.
Background technology
Treat lumbar disc herniation at present, apply the puncture needle that non-endoscope nucleus pulposus excises, be not in contact with it through being directly directed to fibrous ring in the middle part of hernia shape protruding parts through vertebral plate lateral border.In puncture needle, import photoconductive tube, by it, laser emission acted directly on hernia shape protruding parts (direct boiling).Along with forming vaporization duct in fibrous ring, move photoconductive tube and puncture needle along nucleus pulposus direction by conduit terminad, and then direct highlight district at hernia shape and be vaporized.Operate and carry out under monitoring, generally use fluorescent screen perspective X-ray monitoring, magnetic resonance visual monitor and computer body layer x-ray fluoroscopy.Deficiency is that the puncture needle that non-endoscope nucleus pulposus excises is without scale mark pin, in operative process, it is impossible to by length scale mark as whole with reference to being finely adjusted.Then need by, under discontinuous or continuous x-ray fluoroscopy, being adjusted.So patient can be caused unnecessary RADI, medical and nursing work personnel can be caused unnecessary RADI equally.
On the other hand, need over the course for the treatment of to judge roughly length in reserve by artificial contrast's needle length and by vision, and make bare optical end be about 1cm beyond needle length, the most manually control medical laser optical fiber reciprocating by puncture needle along nucleus pulposus direction, and then directly highlight district at hernia shape and be vaporized.In this operating process, judgement to length is judged roughly by vision mostly, on medical angle, the most rigorous, and when operator's Non-follow control medical laser optical fiber is reciprocating, need by thumb and show that finger fixes medical laser optical fiber, requirement for operator is the highest, the highest with time error and dangerous hidden danger, because bare optical end temperature can the most about 300 DEG C, as in operation, naked end enters inside puncture needle, puncture needle temperature can be made to raise, thus the tissue being damaged on puncture path or nerve.There is sizable dangerous hidden danger.
Summary of the invention
Goal of the invention: the present invention is a kind of nucleus pulposus excision puncture needle, it is an object of the invention to solve that existing equipment needs present in the operation to be adjusted by discontinuous or continuous x-ray fluoroscopy, optical fiber stretches out the length of needle tubing and is difficult to judge and the problem such as control.

Detailed description of the invention:
The technological thought of the present invention is: be provided with the device of grip optical fiber at needle tubing rear portion, move before and after limiting optical fiber by spring 4 and adapter sleeve 5, avoid operation controls optical fiber the most by rule of thumb, naked end enters inside puncture needle, puncture needle temperature can be made to raise, thus the tissue being damaged on puncture path or nerve.Additionally the present invention is provided with scale annulus on cast staight needle 1-2 and optical fiber so that operation can depart from x-ray fluoroscopy and carries out, and decreases patient and time that Shi patient is radiated, it is to avoid people causes the harm in health.
The present invention is implemented by below scheme, as shown in Figure 2:
The present invention is that a kind of non-endoscope nucleus pulposus excises puncture needle, including puncture needle 1, rear lock sleeve 2, front lock sleeve 3, adapter sleeve 5；Described rear lock sleeve 2 is threaded connection with front lock sleeve 3；Rubber sleeve 6 in cavity between described rear lock sleeve 2 and front lock sleeve 3；Described front lock sleeve 3 is connected with puncture needle handle 1-1 by adapter sleeve 5；Between described front lock sleeve 3 and adapter sleeve 5, spring 4 is installed.
In described adapter sleeve 5, front lock sleeve 3 front end is 0.5cm with the distance of puncture needle handle 1-1 tail end.0.5cm is the reciprocating stroke range of optical fiber in operation, and the effect of adapter sleeve 5 is to define the distance range between front lock sleeve 3 and puncture needle handle 1-1 so that it is the two moves between 0-0.5cm, thus limits the active strokes of optical fiber.
Described adapter sleeve 5 or snaps connection by screw thread with puncture needle handle 1-1.As in figure 2 it is shown, the parts of adapter sleeve and adapter sleeve left can overall disassemble from puncture needle, execute patient and can inject medicine at this moment in puncture needle 1,
Described puncture needle 1 includes tubular staight needle 1-2 and handle 1-1；Described tubular staight needle 1-2 end is bent at an acute angle with the longitudinal axis, is connected with handle 1-1 at near-end, and final section deviates the overbending direction of the longitudinal axis in the same direction with bending end；The surface of described tubular staight needle 1-2 has the annulet being intervally arranged, the distance between each annulet to be 1cm.This annulet can make to execute that patient directly judges puncture needle 1 thrusts the degree of depth, is that syringe needle accurately arrives affected part, avoids in prior art the drawback needing persistently to carry out x-ray fluoroscopy simultaneously.
Described non-endoscope nucleus pulposus excision puncture needle, it is characterised in that: the end of tubular staight needle 1-2 and longitudinal axis are 20-40 ° of angle, and the end bending of described tubular staight needle 1-2 is 5-25 ° of angle with longitudinal axis；On described tubular staight needle 1-2 ends cut cross section at cutting, the axial section in bending part vertical plane cross section is 12-70 ° with the angle of final section projection.Cast staight needle shape be according to operation in human intervertebral disc internal structure definition.
Present invention additionally comprises medical laser optical fiber, described medical laser optical fiber is clamped by rubber sleeve 6 and fixing in front lock sleeve 3, rear lock sleeve 2 hole；Have, on described medical laser optical fiber, the scale marker being spaced apart 1cm.Front and back threaded between lock sleeve leaves surplus, and when screwing, the rubber sleeve 6 in its cavity is crushed, and middle duct reduces, thus clamping effective to optical fiber.Scale marker on optical fiber contributes to executing patient and judges the extension elongation of optical fiber.
