Abstract
The utility model relates to a lumbar intervertebral disc rear path operation magnifying glass which is used for solving the problem that an appliance is propped openly for operation convenience, belonging to the technical field of medical appliance and comprising a usual laminectomy pulling hook and the light pipe of a cold light source; after improvement, the light pipe of a cold light source is fixed on the lower surface of the handle body of the laminectomy pulling hook; the luminous end of the light pipe protrudes downward and obliquely from a through hole which is arranged on the hook body of the laminectomy pulling hook. In the utility model, a usual laminectomy pulling hook is improved in three aspects; therefore, three advantages are brought; the first advantage is the removal of the barrier which influences a doctor's visual field, which is favorable for carrying operation; the second advantage is that the exudate in the process of the operation can be sucked clearly in time; the third advantage is that a major operation doctor can operate; therefore, labor is saved; the operation cost is reduced. The utility model which is an ideal operative instrument can be used in the ablation of the marrow core of a lumbar intervertebral disc with convenience, rapidity, and proper visual field.
Description
Technical field
This utility model relates to a kind of way of escape distraction instrument when being used for lumbar intervertebral disc disease corrective surgery, belongs to medical apparatus and instruments
Technical field.
Background technology
The laminectomy retractor apparatus is an apparatus commonly used of implementing " windowing " formula lumbar nucleus pulposus enucleation, and when undergoing surgery, the laminectomy retractor device is used to strut the tissue of operative site one side, because art portion position is darker, need join illumination cold light source light guide in addition.Simultaneously, also need be equipped with the tissue that dilator struts opposite side.If blood is oozed out in art portion, also must be equipped with suction pump with the sepage exhaustion of art portion.So many apparatus co-operating just must need several medical personnel to cooperatively interact and undergo surgery, and it is more so not only to take medical personnel, and disorderly no chapter also can seem during operation.In order to address this problem, someone has developed the laminectomy retractor of band cold light source light guide, its cold light source light guide is fixed on the upper surface of laminectomy retractor handle body, and light guide protracts and sagging along the plate body of laminectomy retractor, so that the luminous end of light guide can shine art portion depths.Yet the front end of this upper berth light guide can influence doctor's the visual field, and as much as possible little owing to generally all wishing in the cut-away portions of operative site, therefore, the light guide front end that is configured in small space will become the obstacle that the influence operation is carried out smoothly.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and provide a kind of lumbar intervertebral disc posterior approach to expand visual organ, and this apparatus is answered compact conformation, configuration rationally, and is easy to operate during operation, quick, saves staff.
It is as follows to address the above problem the technical scheme that is adopted:
A kind of lumbar intervertebral disc posterior approach expands visual organ, it comprises laminectomy retractor and cold light source light guide 3, said cold light source light guide 10 is fixed with handle body 8 lower surfaces of laminectomy retractor, the luminous end 3 of light guide from the coupler body 4 of laminectomy retractor the set through hole 2 oblique below lean out.
Above-mentioned lumbar intervertebral disc posterior approach expands visual organ, and handle body 8 lower surfaces of said laminectomy retractor are the suction catheter 9 of suction pump fixedly, and the suction nozzle 1 of suction catheter leans out from the through hole 2 of laminectomy retractor coupler body 4.
Above-mentioned lumbar intervertebral disc posterior approach expands visual organ, the handle body front end upper surface of said laminectomy retractor is provided with the cover 6 of pegging graft, a supporting arm front end of dilator 5 is provided with connection-peg, and connection-peg is plugged on the cover of pegging graft, and dilator 5 is fixed on the top, left side of laminectomy retractor.
This utility model has been done the improvement of three aspects to common used laminectomy retractor, the one, the cold light source light guide is fixed on the lower surface of laminectomy retractor handle body, the light guide luminous end leans out downwards from the coupler body through hole, on the operation face of shining, such structure makes the body of light guide can not influence doctor's the visual field, helps operation and carries out; The 2nd, the suction nozzle of suction pump also is fixed on the below of coupler body through hole, the blood that oozes out in the operation process etc. can in time exhaust; The 3rd, dilator is plugged on above the side of laminectomy retractor handle body, further enlarged the visual field of executing the patient.Like this, an operating doctor can be implemented operation, can save manpower, reduces the operation cost.Adopt this apparatus to carry out the lumbar disc resection of nucleus pulposus, very convenient, fast, the visual field is suitable, is a kind of ideal orthopedics department operating theater instruments.
Description of drawings
Fig. 1 is this utility model structural representation axonometric drawing.
Each label is among the figure:
1 suction nozzle, 2 through holes, 3 luminous ends, 4 coupler bodies, 5 dilators, 6 peg graft overlaps 7 screws, 8 handle bodies, 9 suction catheters, 10 light guides, 11 pipe clamps.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
The lumbar intervertebral disc posterior approach of showing referring to accompanying drawing expands visual organ, it comprises laminectomy retractor and cold light source light guide 10, former cold light source light guide is folded into the below from handle body 8 upper surfaces of laminectomy retractor, influence the doctor visual field, after the improvement it is leant out from through hole 2 set from the coupler body 4 of laminectomy retractor, saved its shared space.
For easy to operate, handle body 8 lower surfaces of laminectomy retractor are the fixing suction catheter 9 of suction pump in addition also, and the suction nozzle 1 of suction pump leans out from the through hole 2 of the coupler body 4 of laminectomy retractor too, and the suction nozzle employing is hose connection, each corner of being convenient to exhaust.
Fixing between the lower surface of the suction catheter 9 of cold light source light guide 10 and suction pump and the handle body 8 of laminectomy retractor can be adopted the fixed form of screw 7, pipe clamp 11.
Medical personnel when performing the operation in order further to reduce, the handle body 8 front end upper surfaces of laminectomy retractor are provided with the fixedly grafting cover 6 of dilator 5, dilator commonly used is two hinged forming of support arm, be provided with the location latch at its handle place, usually must help the hand operated dilator, after this utility model improves, can establish a connection-peg at a supporting arm front end of dilator 5, connection-peg is inserted in the cover 6 of pegging graft, dilator 5 and laminectomy retractor are connected as one, like this, an operating doctor also just can be implemented to have performed the operation.
