Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with
Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein
It applies example to be only used to explain the utility model, is not used to limit the utility model.
Also referring to Fig. 1 to Fig. 3, now radiotherapy localization body film provided by the utility model is illustrated.The radiotherapy
Positioning body film positions patient when for radiotherapy, is used cooperatively with radiotherapy with fixed frame when radiotherapy.The radiotherapy is fixed
Position body film includes upper orientation film 10, the lower orientation film 20 positioned at upper 10 lower section of orientation film, and is adhered under orientation film 10
The vacuum pad 30 on surface and/or the upper surface of lower orientation film 20.The two sides of upper orientation film 10, the two sides of lower orientation film 20 are set respectively
There is card adapter plate 40, card adapter plate 40 with fixed frame for connecting.
Upper orientation film 10, lower orientation film 20 are thermoplastic body film commonly used in the prior art, can be according to demand after heating and softening
Deformation, temperature reduce after-hardening molding.Vacuum pad 30 is by vacuum valve and the plastic particles ball group being fitted into plastics or rubber bag
At being pumped to a degree of negative pressure of vacuum to vacuum pad 30 with vacuum pump, plastic particles ball is pressed against each other and deforms.
Radiotherapy localization body film provided by the utility model use process is as follows:
Upper orientation film 10, lower orientation film 20 are immersed to 60-70 DEG C of constant temperature water tank, sufficiently after softening, by lower orientation film 20
Card adapter plate 40 be placed on the fixed frame of radiotherapy, can the upper surface of lower orientation film 20 paste vacuum pad 30, patient lies supine in
Fixed frame lies low on fixed frame, and patient suppresses lower vacuum pad 30 and lower orientation film 20, and the lower deformation of orientation film 20 is made to meet trouble
(since the thickness of vacuum pad 30 is less than the thickness of lower orientation film 20, and what is filled inside vacuum pad 30 is modeling to the form at person back
Expect particle sphere, when patient pushes, vacuum pad 30 can also be deformed)；Also vacuum pad 30 can be pasted in the lower surface of upper orientation film 10, put
Upper orientation film 10 is covered in the thorax abdomen of patient by treatment personnel, and is fixed on fixed frame, and the upper orientation film 10 of tensile softening makes
Upper orientation film 10 deforms the form for meeting patient's thorax abdomen, and molding is (upper in Fig. 1 after upper orientation film 10, lower orientation film 20 are hardened
Orientation film 10, lower orientation film 20 are undeformed state, i.e., not with the state of patient contact, in practical application, the two removes two sides
Edge contact is outer, remaining position does not contact, and patient is positioned there between).Since upper orientation film 10, lower orientation film 20 are formed
When, patient may fine motion, cause orientation film sizing there are deviation, may between upper orientation film 10, lower orientation film 20 and patient
There are gap, Radiotherapy personnel is by observing the gap between upper orientation film 10 or lower orientation film 20 and patient, with vacuum pump to true
Empty pad 30 is pumped to a degree of negative pressure of vacuum, and the plastic particles ball of vacuum pad 30 is pressed against each other, and vacuum pad 30 deforms, thus
Fill up the gap of patient and upper orientation film 10, lower orientation film 20.
Radiotherapy localization body film provided by the utility model, compared with prior art, lower orientation film 20 are used for patient lies supine
Back afterwards is positioned, and lower orientation film 20 is capable of the back of secure fit patient, avoids depositing between patient back and fixed frame
The problem of gap causes patient's fine motion to influence therapeutic effect；It can also be glued on the positioning surface of upper orientation film 10 or lower orientation film 20
Vacuum pad 30 is connect, vacuum pad 30 forms after being evacuated according to the posture of patient lies supine, can fill up orientation film 10 or lower orientation film 20
With the gap of patient, further improve positioning accuracy, and the pendulum position of vacuum pad 30 by radiotherapy doctor's subjective factor influenced compared with
Small, the movement of launched field center is smaller.
Specifically, there are two vacuum pad 30 is set, refering to fig. 1, respectively with the top of the bottom surface of upper orientation film 10, lower orientation film 20
Face bonding.
Specifically, card adapter plate 40 includes top plate 41, bottom plate 42, and the side plate 43 of connection top plate 41 and bottom plate 42, top plate
41, side plate 43 and bottom plate 42 are an integral molding structure；The outside of side plate 43 is equipped with knob 60；The bottom surface of top plate 41, bottom plate 42
The medial surface of top surface and side plate 43 surrounds the groove for being clamped upper orientation film 10 or lower orientation film 20, refering to Fig. 3.On making
Orientation film 10, lower orientation film 20 are clamped securely, are equipped at intervals with multiple threaded holes along its length respectively on top plate 41 and bottom plate 42,
It is provided in each threaded hole and tightens screw 50, the screw cap end for tightening screw 50 is located inside threaded hole, that is to say, that tightens
The screw cap end of screw 50 does not protrude from top plate 41 or bottom plate 42, will not influence the card adapter plate 40 and lower positioning of orientation film 10 in this way
The card adapter plate 40 of film 20 contacts, and the screw rod end for tightening screw 50 passes through threaded hole and connects with upper orientation film 10, lower orientation film 20.
50 one side of screw is tightened for fastening orientation film 10 and lower orientation film 20, tighten tighten screw 50 can make it is fixed
Position film 10 and lower orientation film 20 and 40 fixation of card adapter plate, orientation film 10 and lower positioning can be made by tightening 50 another aspect of screw
Film 20 is separated with card adapter plate 40, and release tightens screw 50, and upper orientation film 10 and lower orientation film 20 by top plate 41, bottom plate 42 and are not adjusted
Tight screw 50 can separate its pressure, card adapter plate 40 with upper orientation film 10 and lower orientation film 20.Upper orientation film 10 and lower positioning
Film 20 and card adapter plate 40 are that separate structure can be individually replaced orientation film 10 after upper orientation film 10 or lower 20 aging of orientation film
Or lower orientation film 20, card adapter plate that no replacement is required 40, so that the positioning body film has the low feature of replacement cost.
In order to keep the placement location of upper orientation film 10 and lower orientation film 20 accurate, even card adapter plate 40 is precisely fixed on fixation
On frame, as a kind of specific embodiment of radiotherapy localization body film provided by the utility model, it is equipped at intervals on side plate 43 multiple
Location hole 44, location hole 44 are used to cooperate with the positioning column on fixed frame, and card adapter plate 40 can be enable to be positioned accurately at fixation
On frame.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
