Description
Technical field
The invention belongs to human body positioning device technical fields in radiotherapy, are related to a kind of Tenon card shelves formula radiotherapy head
Neck positions Hollow pillow tablet fixed frame, is the device that incidence positions in a kind of radiotherapy, it is big to be suitable for physical activity degree
Incidence entirety it is fixed, be the important component for being accurately positioned, implementing in modern radiotherapy.
Background technology
Low temperature thermo-plastic planking (film) is a kind of macromolecule polyester of special synthesis, is handled through a series of physical and chemical method
Made of new medical material, for radiotherapy Postural immobilization, making materials such as fixation, orthoses, brace outside orthopaedics.Due to
The material (works as modeling after ray, heating and softening with not absorbing with good plastotype effect and specific shape memory function
Type can reheating, again plastotype or local heating shape again when dissatisfied) etc. outstanding properties and easy to operate, fixed
It is convenient, it is optimal external fixation system in current radiotherapy localization.
Currently, the fixation of patient mostly uses greatly Low Temperature Thermal mould plate material the fixed mode of machinery is combined to reach in clinical radiotherapy
To the purpose of positioning.The requirement of the positioning of radiotherapy：Fixed accurate, mobile mistake is required on the three-dimensional of top to bottom, left and right, front and rear
Difference<5MM.Neck position anatomical structure is compact, and various vitals are distributed with.It is fixed by mobilizers such as mandibular, cervical vertebras
The influence of the physiological activities such as the limitation of official, and breathing, heartbeat.Control error is fixed in the radiotherapy that factors above causes incidence
It is difficult.Although mechanical means are various on the market, there are displacement errors mostly for detection discovery in practical effect.
The deficiency of radiotherapy localization at present：1. position (part) is fixed, limit is incomplete；2. it is not good enough that spinal cord puts position repeatability；
3. Target localization error caused by being shaken due to upper limb can not be solved；4. the movement that can not solve upper body causes head error；5.
It can not solve decaying of the base plate for ray；6. low temperature thermoplastic film and bottom plate there are fixed interval (FI)s；7. can not solve by
In the head error that cervical rotation, bending and stretching are brought；8. fixing locking mechanical structure to be stressed directly；9. fixation procedure is easily sent out
Raw locking falls off, fixed failure；10. fixation procedure causes (shoulder) skin to squeeze folder injury accident；11. face compressing, comfort
It is not good enough；12. standing finish fission designs, easy to be lost；13. laborious, cumbersome using operating；14. resetting accuracy is poor.It is based on
We devise a radiotherapy localization fixing device for the above deficiency and drawback, mainly solve it is above it is insufficient in the 1st, 2,3,
4 and the problem of 5.

On 80 clamping lock of pivot pin realization rotated together with helical axis 77.The line shaft 74 and transaxle 75 sent out on main braces 71, with pair
Braces plate 68 is connected, and thumb wheel 69 and power teeth 72 connect traveling on line shaft 74, and rely on axis bolt on line shaft 74
80 fix realization three rotates simultaneously, and through transaxle 75, the axis that can have mercy on is freely rotated dress gear changing 76.Power teeth 72 turns
Gear changing 76 and 78 three of helical tooth intermeshing, the rotation of thumb wheel 69, which will pass sequentially through, drives power teeth 72,76 and of conversion gear
Helical tooth 78, the final rotation for realizing helical axis 77.The wheel of thumb wheel 69 (is joined along the form friction pattern 73 for increasing force of sliding friction is designed with
See Figure 10) thumb wheel 69, in outer surface, is conveniently operated the use of personnel from 67 partial denudation of thumb wheel mouth on tooth case lid 66.Ginseng
See Figure 12,13,14, " taenidium into 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 cover 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 be convex 92, seat nut 93, taenidium 94, secondary calibration block 95, silk are into slot 96, lower cover ditch 97, driven bearing
99 and follower plate 100 constitute.Its agent structure is the silk that constitutes of secondary calibration block 95, master calibration block 88 and bottom cut board 90 into slot 96.
Follower plate 100 and main braces 71 are located at silk into the both ends of slot 96；Two seat guide rails 89 are located at silk into the two side of slot 96
Between.Helical axis 77 runs through entire silk by the driven bearing 99 in the active bearings 79 and follower plate 100 on main braces 71
Into slot 96.It is covered with taenidium 94 with helical axis 77.Handle seat 91 is by the seat nut 93 positioned at 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 rotates, taenidium 94 will pass through seat spiral shell
Female 93 screw drives handle seats 91, handle seat 91 are realized in silk due to the limitation in the present guide rail 89 of its both sides seat convex 92 into slot 96
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 difference travelings, into the upper cover ditch 83 and lower cover ditch 97 of the upper limb of 96 two side of slot, pass through upper volume ring 86 and last volume ring respectively in silk
84 overlapping lantern rings is set to the root of arbor 36, while also constitute silk into slot 96 head cover.Upper roll-top 87 and lower roll-top 82 begin
In the reel assembly 81 on main braces 71 and follower plate 100.When 91 displacement of handle seat is slided, drive arbor 36 connected to it same
Shi Yundong, be sleeved on 36 root of arbor upper volume ring 86 and last volume ring 84 also will movement, the upper roll-top 87 that is connected with respective ring and under
Roll-top 82 will the sliding in respective lid ditch (upper cover ditch 83 and lower cover ditch 97).Silk will realize the shape covered into 96 top of slot at this time
State, it is such arbor moves.Referring to Figure 15, " reel assembly 81 " formula two is located at main braces 71 and follower plate
On 100, for the component of curling storage cover board.By lower roll-top 82 (or upper roll-top 87), scroll rack 85, backrush pin 98, backrush spring
399 and backrush axle 400 form.Agent structure is two opposite scroll rack 85 set up, and backrush axle 400 is lain across in the middle part of the two；It returns
Coil spring 399 is surrounded on the both ends of backrush axle 400 by backrush pin 98；Lower roll-top 82 (or upper roll-top 87) passes through lower cover ditch 97
(or upper cover ditch 83) is wound in backrush axle 400.399 stress of backrush spring exists compel always in backrush pin 98 and scroll rack 85
The elastic force potential energy for making backrush axle 400 rotate, realizes that upper (lower) roll-top 87 keeps the state of smooth masking.When use：Operating personnel
Thumb wheel 69 is stirred, the rotation of thumb wheel 69, which will pass sequentially through, drives power teeth 72, conversion gear 76 and helical tooth 78, meshing spiral axis
77 rotation；When helical axis 77 rotates, taenidium 94 will be sent out by 93 screw drives handle seat 91 of seat nut along seat guide rail 89
Raw displacement movement realizes that arbor 36 also moves simultaneously.The moving displacement of handle 37 can quantify to indicate by scale 65.Arbor 36
Movement drives the movement for rolling up ring 86 and last volume ring 84, and upper roll-top 87 and lower roll-top 82 are respectively along upper cover ditch 83 and lower cover ditch 97
It is subjected to displacement movement；The rotation of backrush spring 399 is pushed and pulls again, at the same time, stress is in backrush pin 98 and scroll rack 85
Backrush spring 399 there is the elastic force potential energy for forcing backrush axle 400 to rotate always, the upper roll-top 87 of realizations and the holding of lower roll-top 82 are put down
The state of whole masking.It entire theory of mechanics and is completed using process.
