Description
Technical field
The invention belongs to clinical medicine domain, be specifically related to a kind of non-endoscope nucleus pulposus excision puncture needle being used for the treatment of prolapse of lumbar intervertebral disc.
Background technology
Current treatment prolapse of lumbar intervertebral disc, applies the puncture needle of non-endoscope nucleus pulposus excision, gives prominence to direct guide fiber ring in the middle part of position and be not in contact with it through vertebral plate lateral border through hernia shape.Lead-in light conduit in puncture needle, acts directly on hernia shape by it by laser emission and gives prominence to position (direct boiling).Along with forming vaporization duct in fibrous ring, moving light guide and puncture needle along vertebral pulp direction by conduit terminad, and then directly vaporizing at hernia shape protruding segments.Carry out under operating in monitoring, usually use the monitoring of fluorescent screen perspective X-ray, magnetic resonance visual monitor and computer body layer x-ray fluoroscopy.Deficiency is that the puncture needle of non-endoscope nucleus pulposus excision is without scale mark pin, in operative process, cannot carry out inching as a reference by length scale labelling.Then need, by under discontinuous or continuous x-ray fluoroscopy, to adjust.Unnecessary RADI can be caused to patient like this, unnecessary RADI can be caused to medical and nursing work personnel equally.
On the other hand, need over the course for the treatment of by artificial contrast's needle length and judge length in reserve roughly by vision, and make bare optical end exceed needle length to be about 1cm, then manually control medical laser optical fiber reciprocating by puncture needle along vertebral pulp direction, and then directly vaporize at hernia shape protruding segments.In this operating process, mostly come to judge roughly by vision to the judgement of length, on medical angle, very not 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 very high, with time error and dangerous hidden danger also very high, because bare optical end temperature can highly about 300 DEG C, as in operation, naked end enters puncture needle inside, puncture needle temperature can be made to raise, thus the tissue be 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, the object of the invention is to solve the length of being undertaken adjusting, optical fiber stretches out needle tubing by discontinuous or continuous x-ray fluoroscopy that needs that existing equipment exists in operation and is difficult to judge and the problem such as control.

Advantage and effect: by enforcement of the present invention, the advantage that can reach and effect have: can limit optical fiber at accurate range of motion, avoid bare optical end in operation to enter puncture needle inside, puncture needle temperature is raised, is damaged to the tissue on puncture path or nerve; The prolonged exposure of X-ray can also be departed from Shi Shuzhong, avoid X-ray and have an X-rayed the injury that doctor and patient are caused continuously.
accompanying drawing illustrates:
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is generalized section of the present invention;
Fig. 3 is needle portion schematic diagram.
Mark in figure:
1 puncture needle, 1-1 puncture needle handle, 1-2 cast staight needle;

detailed description of the invention:
Technological thought of the present invention is: the device being provided with grip optical fiber at needle tubing rear portion, seesawing of optical fiber is limited by spring 4 and adapter sleeve 5, avoid only controlling optical fiber by rule of thumb in operation, naked end enters puncture needle inside, puncture needle temperature can be made to raise, thus the tissue be damaged on puncture path or nerve.The present invention is provided with scale annulus on cast staight needle 1-2 and optical fiber in addition, makes operation can depart from x-ray fluoroscopy and carries out, and decreases the time that patient and Shi patient are subject to radiation, avoids the harm caused people in health.
The present invention is implemented by following scheme, as shown in Figure 2:
The present invention is a kind of non-endoscope nucleus pulposus excision puncture needle, comprises 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, the distance of front lock sleeve 3 front end and puncture needle handle 1-1 tail end is 0.5cm.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, makes to move between 0-0.5cm both it, thus limits the active strokes of optical fiber.
Described adapter sleeve 5 is connected by screw thread or buckle with puncture needle handle 1-1.As shown in Figure 2, the parts of adapter sleeve and adapter sleeve left can overall disassemble from puncture needle, and executing patient can at this moment to injectable drug in puncture needle 1,
Described puncture needle 1 comprises tubular staight needle 1-2 and handle 1-1; It is acute angle that described tubular staight needle 1-2 end is bent into the longitudinal axis, and be connected with handle 1-1 at near-end, final section and bending end depart from the overbending direction of the longitudinal axis in the same way; There is the annulet be intervally arranged on the surface of described tubular staight needle 1-2, and the distance between each annulet is 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 to continue to carry out x-ray fluoroscopy simultaneously.
Described non-endoscope nucleus pulposus excision puncture needle, it is characterized in that: the end of tubular staight needle 1-2 and longitudinal axis are 20-40 ° of angle, the end bending of described tubular staight needle 1-2 is 5-25 ° of angle with longitudinal axis; Described tubular staight needle 1-2 ends cut is on the transverse section of cutting place, and the angle that the axial section of bending part vertical transverse section and final section project is 12-70 °.Cast staight needle shape be according to operation in human intervertebral disc internal structure definition.
The present invention also comprises medical laser optical fiber, and described medical laser optical fiber is clamped by rubber sleeve 6 and fixes in front lock sleeve 3, rear lock sleeve 2 hole; Described medical laser optical fiber there is the scale marker being spaced apart 1cm.Being threaded between the lock sleeve of front and back leaves surplus, and the rubber sleeve 6 when screwing in its cavity is crushed, and middle duct reduces, thus effectively clamps optical fiber.Scale marker on optical fiber contributes to executing the extension elongation that patient judges optical fiber.
