Description

The laminectomy retractor assistor

Technical field

This utility model relates to a kind of medical instruments, the operational tool in especially a kind of vertebral body operation.

Background technology

The surgeon is when implementing vertebral body operation, often by means of laminectomy retractor, paraspinal muscle is retracted to expose operating field, method be operative doctor with laminectomy retractor before hook be fixed on vertebral plate, tie up on the rear hook of laminectomy retractor with an end of rope, then the other end of rope is thrown away under operation table, then by the circuit nurse, rope is tied up on the operation table base or on operation table edge or other adnexaes, perhaps tramped with one's feet by operative doctor.Old money operation table adopts that machinery adds that manual method adjusts that height, the left and right sides of the head of operation table or foot turn, the adjustment of the head of a bed or tailstock segmentation, and this is by means of the adnexa of operation table: handle and runner and ratch are accomplished.Along with operation table style, performance are constantly updated, motorized operating bed replaces the operation table of mechanical type, has cancelled handle and runner and ratch, and without the place of rope binding, in addition, the electric operation bed foundation that now uses and the distance on ground only are 2cm to the base of bed.The method that adopts doctor's foot to step on easily makes operative doctor divert one's attention, and attention can not be concentrated.In addition, by the method for circuit nurse at operation table edge tether, following situation can occur: (1) circuit nurse must reach head under surgical drage for fear of operating field is contaminated, and optimum orientation that often can not fine judgement stay cord causes the pulling force out of plumb to make the drag hook position become tiltedly easily displacement; The final cloth list that also can occur below an edge is up rolled up and is caused aseptic area contaminated; (2) circuit nurse seeks and convenient directly the following cloth list of bed edge is up raised sometimes, also causes aseptic area to pollute.

Summary of the invention

This utility model provide a kind of flexible, simple in structure, effectively avoid that operating field pollutes the laminectomy retractor assistor.

For achieving the above object, the technical solution of the utility model is:

A kind of laminectomy retractor assistor comprises rope, it is characterized in that:

Also comprise fixedly assistor, wherein:

Described fixedly assistor comprises fixing head and fixed bar, and fixing head is rectangle, is fixedly connected with fixed bar above fixing head, and the upper end of fixed bar is bent into circle;

The lower end of described rope lies on the circle of fixed bar, and the upper end is connected with the lower end of drag hook.

Be provided with can be freely supporting slope shape wooden unit on fixing head.

The laminectomy retractor assistor of above structure has following advantage and positive effect:

(1) fixedly laminectomy retractor is convenient to use the laminectomy retractor assistor, and is reliable for effect flexibly, both adapted to the variation requirement of New-type operating bed, also can use at old money operation table;

(2) avoid causing in the operation of operation table edge the possibility that operating field pollutes;

(3) avoid the doctor can not attentively operate because tramping with one's feet rope, also avoid the assistant to hinder the probability of operator operation to occur when drag hook;

Without assistant's problem, sometimes also play assistant's effect when (4) can fine solution doctor being short of hands.When being short of hands, operating doctor can use assistor to help drag hook to expose preferably the otch visual field;

(5) grasped the drag hook of homonymy by operation operator person oneself, need not the assistant opposite or the side and stretch out one's hand fixedly laminectomy retractor, to the broader working place of operator person.

Description of drawings

Fig. 1 is use structural representation of the present utility model;

Fig. 2 is the right TV structure schematic diagram of Fig. 1;

In figure, fixing head 1, wooden unit 2, rope 3, laminectomy retractor 4, circle 5, fixed bar 6.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Shown in Figure 1, it is front view of the present utility model, comprise fixedly assistor and rope 3, wherein: fixedly assistor is comprised of fixing head 1 and fixed bar 6, fixing head 1 is rectangle, is fixedly connected with fixed bar 6 above fixing head 1, in conjunction with shown in Figure 2, be the right TV structure schematic diagram of Fig. 1, the upper end of fixed bar 6 is bent into circle 5 so that tether 3; The lower end of rope 3 lies on the circle 5 of fixed bar 6, and the upper end is used for being connected with laminectomy retractor 4.Also be provided with can be freely supporting slope shape wooden unit 2 on fixing head 1.

The laminectomy retractor 4 of using in the operation at present is generally the front hook that is formed for inserting vertebral plate after the bending of top, and rear hook is the arc crotch, and rope 3 ties up to arc crotch place.

First this assistor is positioned under the operation table base before the operation beginning, treat that operator fixes the front hook of laminectomy retractor 4, rear hook one circle is walked around in the upper end of rope 3, put down the lower end of rope 3 under bed, give on the circle 5 of the laminectomy retractor assistor that circuit nurse's colligation has been placed on the operation table base in the preoperative, the domatic wooden unit is placed on fixing head 1 then both is advanced the operation table base together, domatic wooden unit 2 can firmly be fixed on assistor position suitable under operation table and be difficult for mobile; Operative doctor can be adjusted position and the elasticity of laminectomy retractor 4 as required.If need to move up and down laminectomy retractor 4 positions, unclamping a little domatic wooden unit 2 just can movement assist device, and rope 3 can vertically be held laminectomy retractor 4 all the time.
