Detailed Description
The present invention will be described in further detail with reference to the following specific examples and the accompanying drawings. The procedures, conditions, experimental methods and the like for carrying out the present invention are general knowledge and common general knowledge in the art except for the contents specifically mentioned below, and the present invention is not particularly limited.
A human fixing device for radiotherapy location in this embodiment, it includes:
and a substrate made of a carbon fiber material that is transparent to radiation, wherein 4 engaging holes having a square shape of 5cm are formed in the substrate. In practice, the number, shape and position may be set as desired.
The moulding pad, its inside is filled a large amount of little foam granules, and moulding pad lower right corner has a aperture and can takes out the gassing to it, and whole moulding pad sclerosis and indeformable after the evacuation. After the patient lies on the shaping pad, the doctor vacuumizes the shaping pad, so that the shaping pad is completely hardened to form a fixed shape, and the patient can keep the action consistent with the last time when lying on the shaping pad in the next radiotherapy.
The bottom of the shaping pad is provided with a rigid clamping block; when the shaping pad is placed on the substrate, the clamping hole and the clamping block can be clamped with each other, so that the shaping pad cannot be displaced with the substrate due to the action of a patient to influence the radiation precision. The number, shape and position of the clamping blocks are matched with the clamping holes.
Near base plate both sides edge all is provided with perpendicular ascending limiting plate, and moulding pad is placed between two limiting plates, and the moulding pad of restriction not evacuation can not too spread out to both sides, avoids the moulding effect that the foam particle leads to inadequately in moulding pad under the patient is normal.
The deepened protrusions are arranged around the engaging holes in the present embodiment, and the carbon fiber material of the substrate is very expensive, so that the substrate cannot be made thick in consideration of cost, but the engaging block cannot be firmly fixed to the engaging holes. The periphery of the shaping hole is deepened, so that the clamping effect is better, and the probability of displacement between the substrate and the shaping pad is further reduced.
The thickness of the deepening bulge is 2 cm, and can be changed according to actual needs.
Considering that some radiotherapy treatments require head fixation, the base plate of this embodiment is provided with a head fixation plate, which is also made of the same material as the base plate, and the patient can place the head thereon.
In this embodiment, the shaping pad is provided with a head shaping portion communicated with the shaping pad, and the head of the patient can be shaped and fixed after the head is put on the shaping pad and vacuumized.
Further, the present embodiment further includes a shaping cover; the shaping cover is in a grid shape, is made of thermoplastic material, and clamping grooves are arranged on two sides of the shaping cover and can be mutually clamped with fixing grooves arranged on the base plate on the outer side of the limiting plate, so that the upper part of the body of the patient is also fixed.
When the shaping cover is used, the shaping cover needs to be placed into hot water for heating and softening, then is applied to a patient body, the clamping groove is fixed in the fixing groove, the shaping cover is shaped after being cooled, and the current action of the patient is restored by the shaping cover when the shaping cover is used next time so as to improve the precision.
The utility model discloses well draw-in groove can adopt arbitrary structure with the fixed mode of cooperation of fixed slot, as long as can realize this function. The groove is formed in the groove wall of the fixing groove, the protrusion is arranged on the clamping groove, and the protrusion is inserted into the groove to achieve the fixing function.
The protection of the present invention is not limited to the above embodiments. Variations and advantages that may occur to those skilled in the art may be incorporated into the invention without departing from the spirit and scope of the inventive concept, and the scope of the appended claims is intended to be protected.
