Abstract
The invention provides a mortise-tenon handle type radiotherapy head and neck positioning slab fixing rack, comprising a fixing rack, a headrest and a head membrane. The slab fixing rack is a head and neck precision radiotherapy positioning fixing system, wherein the braking direction of an upper limb limiter is spirally cross with the adjusting torque to realize one-way braking and limit and fix human head, thereby achieving or approaching zero displacement; and all shortcomings of the present head radiotherapy structure are effectively solved. By matching the special fixing head membrane, the action of the upper limb can be limited, and braking of shoulder joints can be kept, so that precision positioning is achieved. The slab fixing rack is particularly suitable for radiotherapy positioning of head, neck, vertebral columns and other like parts. The slab fixing rack is reasonable in design, convenient to operate, safe, environment-friendly, obvious in fixing effect and strong in practicability and universality.
Description
Technical field
The invention belongs to human body positioner technical field in radiotherapy, is related to a kind of Tenon handle type radiotherapy head
Cervical region location panel fixed mount, is a kind of device of incidence positioning in radiotherapy, is suitable for the big head and neck of physical activity degree
The entirety in portion is fixing, is the important component part for being accurately positioned in modern radiotherapy, implementing.
Background technology
Low temperature thermo-plastic planking (film) is a kind of macromolecule polyester of special synthesis, processes through series of physical and chemical method
New medical material, for the making material such as fixation, orthosiss, brace outside radiotherapy Postural immobilization, orthopaedics.Due to
The material have do not absorb ray, heat and soften after (work as modeling with good plastotype effect and specific shape memory function
Type can post bake, again plastotype or local heating shape again when dissatisfied) etc. outstanding properties, and simple to operate, fixing
Convenient, it is optimal external fixation system in current radiotherapy localization.
At present, in clinical radiotherapy, the fixation of patient is reached mostly by the way of low temperature thermo-plastic planking combines and is mechanically fixed
Purpose to positioning.The requirement of radiocurable positioning：Require on the three-dimensional of top to bottom, left and right, front and rear to fix accurately, movement is by mistake
Difference<5MM.Head and neck position anatomical structure is compact, and various vitals are distributed with.Which is fixed by mobilizers such as mandibular bone, cervical vertebras
The restriction of official, and the impact of the physiological activity such as breathing, heart beating.Factors above causes the radiotherapy of incidence and fixes control error
Difficult.Although mechanical means are various on the market, detection in practical effect finds there is mostly displacement error.
The deficiency of current radiotherapy localization：1. position (part) is fixing, spacing incomplete；2. spinal cord pendulum position repeatability is not good enough；
3. cannot solve to rock, due to upper limb, the Target localization error for causing；4. the movement that upper body cannot be solved causes head error；5.
The presence fixed interval (FI) of low temperature thermoplastic film and base plate；6. cannot solve to miss due to the head that cervical rotation, bending and stretching are brought
Difference；7. fix locking mechanical structure to be stressed directly；8. fixation procedure easily occurs locking to come off, fixing failure；9. fixation procedure is made
(shoulder) skin is become to squeeze folder injury accident；10. face compressing, comfortableness is not good enough；11. standing finish splits are designed, easy to lose；
12. is laborious, loaded down with trivial details using operation；13. resetting accuracys are poor.Based on above deficiency and drawback, we devise a putting
Treat device for positioning and securing, its mainly solves the problems, such as above not enough in the 1st, 2,3 and 4 points.

On 80 kayser of pivot pin realize rotate together with helical axis 77.The line shaft 74 for sending on main braces 71 and transaxle 75, with pair
Braces plate 68 is connected, and thumb wheel 69 and power teeth 72 connect traveling on line shaft 74, and rely on 74 upper shaft latch of line shaft
80 fixings realize three while rotating, and dress gear changing 76 is through transaxle 75, and axle of can having mercy on freely is rotated.Power teeth 72, turn
Gear changing 76 and 78 three of helical tooth engage each other, and thumb wheel 69 is rotated and will pass sequentially through drive power teeth 72,76 and of conversion gear
Helical tooth 78, finally realizes the rotation of helical axis 77.Thumb wheel 69 is taken turns along the form friction pattern 73 for being designed with increase force of sliding friction, (ginseng
See Figure 10) thumb wheel 69 from be located at tooth case lid 66 67 partial denudation of thumb wheel mouth in outer surface, facilitate the use of operator.Ginseng
See Figure 12,13,14, " taenidium enters component 38 " is the core component of the accessory, by arbor 36, main braces 71, helical axis 77, volume
Shaft assembly 81, lower roll-top 82, upper lid ditch 83, last volume ring 84, upper volume ring 86, upper roll-top 87, master calibration block 88, seat guide rail 89, bottom
Frid 90, handle seat 91, seat are convex 92, seat nut 93, taenidium 94, secondary graduated tile 95, silk enter groove 96, lower cover ditch 97, driven bearing
99 and follower plate 100 constitute.The silk that its agent structure is secondary graduated tile 95, master calibration plate 88 and bottom cut board 90 are constituted enters groove 96.
Follower plate 100 and main braces 71 enter the two ends of groove 96 respectively positioned at silk；Two seat guide rail 89 enters in the two side of groove 96 positioned at silk
Between.Helical axis 77 runs through whole silk by the driven bearing 99 being located in the active bearings 79 and follower plate 100 on main braces 71
Enter groove 96.It is covered with taenidium 94 with helical axis 77.Handle seat 91 is by being located at the seat nut 93 of its central through helical axis
77；91 both sides of handle seat are designed with seat convex 92, and traveling is in seat guide rail 89；When helical axis 77 is rotated, taenidium 94 will be by seat spiral shell
Female 93 screw drives handle seats 91, handle seat 91 is realized entering groove 96 in silk due to the restriction in the present guide rail 89 of its both sides seat convex 92
The displacement movement of long axis direction.(referring to Figure 13) " arbor 36 " is located at 91 center upper portion position of handle seat.Upper roll-top 87 and lower roll-top
82 respectively traveling enter the upper lid ditch 83 of upper limb and the lower cover ditch 97 of 96 two side of groove in silk, respectively by upper volume ring 86 and last volume ring
The 84 overlap collars are arranged at the root of arbor 36, while also constituting the top cover that silk enters groove 96.Upper roll-top 87 and lower roll-top 82 begin
Reel assembly 81 on main braces 71 and follower plate 100.When 91 displacement of handle seat is slided, drive connected arbor 36 same
Shi Yundong, be enclosed within the upper volume ring 86 of 36 root of arbor and last volume ring 84 also will motion, upper roll-top 87 connected with respective ring and under
Roll-top 82 will be slided in respective lid ditch (upper lid ditch 83 and lower cover ditch 97).Now silk enters the shape that 96 top of groove will be realized covering
State, even if arbor motion is also such.Referring to Figure 15, " reel assembly 81 " formula two, it is located at main braces 71 and follower plate respectively
On 100, it is the part of curling storage cover plate.By lower roll-top 82 (or upper roll-top 87), scroll rack 85, backrush pin 98, backrush spring
