In addition, optionally, in some embodiments of the present application, in order to improve the sliding stroke of the sliding portion 321 relative to the mounting plate 200, one end of the sliding groove 3211 extends into the slot 324; when the fixing member 310 moves in the sliding groove 3211 so that the fixing member 310 corresponds to the inside of the slot 324, in order to facilitate the operation of the fixing member 310, a notch 3231 is formed on the limiting portion 323, and the notch 3231 is disposed corresponding to the sliding groove 3211; a user can pass through the notch 3231 to extend into the sliding groove 3211, thereby facilitating the operation of the fixing member 310.

In the embodiment of the present application, the mounting plate 200 includes a connection portion 210 and a mounting portion 220.

One side of the connection part 210 is connected to one side of the base plate 100, and the connection part 210 is inclined with respect to the base plate 100 such that the base plate 100 forms a U-shape together with the two mounting plates 200; in addition, the mounting plate 200 may be regarded as being inclined with respect to the base plate 100. It should be noted that, in some embodiments of the present application, in order to facilitate the installation of the vacuum pad on the base plate 100, the connecting portion 210 forms an obtuse angle with the base plate 100, so that the two connecting portions 210 substantially form a flaring shape. It is worth noting that in the case that the vacuum pad is installed on the base plate 100, the vacuum pad is located between the two connection portions 210, so that the vacuum pad can be provided with a limit function through the two connection portions 210, and the stability of the installation of the vacuum pad on the base plate 100 is improved. Of course, in other embodiments of the present application, the connecting portion 210 may be disposed to be even with the bottom plate 100, in other words, the connecting portion 210 may be an outer portion of the bottom plate 100.

A mounting portion 220 is provided at the other side of the connection portion 210, and a connector may be engaged with the mounting portion 220 to achieve the fixation of the thermoplastic film; the movable clip 300 is movably disposed on the mounting portion 220, and the movable clip 300 is movable relative to the mounting portion 220 to selectively move toward or away from the thermoplastic film.

After the vacuum pad placement is complete, the patient may move onto the vacuum pad; the vacuum pad can fully contact with the patient to improve the accuracy of patient's pendulum position, reduce the error of repeated pendulum position. Covering the patient with a thermoplastic film while the patient is moved into position on the vacuum pad; and through the both sides of thermoplastic film corresponding to two mounting panels 200 respectively, through the connecting piece run through thermoplastic film and with the cooperation of mounting hole 221 just can realize the location of thermoplastic film, improve the stability that thermoplastic film and patient contacted. The movable buckle 300 can move relative to the mounting plate 200 to clamp the thermoplastic film, so as to further improve the contact stability of the thermoplastic film and the patient. Therefore, the vacuum pad can be limited by the mounting groove 110, so that the position stability of the vacuum pad is ensured; meanwhile, the thermoplastic film is fastened by the cooperation of the connector and the mounting hole 221, and the thermoplastic film is clamped by the movable clamp 300, so that the contact stability of the thermoplastic film and the patient can be ensured, and the movement of the body position of the patient can be effectively inhibited in the treatment process.

It should be noted that, in the case that the fixing frame 10 provided in the embodiment of the present application completes the positioning and fixing of the patient by fixing the vacuum pad and the thermoplastic film, the back and both soft tissues of the patient's body can be fully contacted with the vacuum pad without moving, the therapeutic positioning precision is improved, and the repeated positioning error is less than 2 mm.

In addition, the embodiment of the present application further provides a treatment couch (not shown), which employs the fixing frame 10, and can achieve the technical effect achieved by the fixing frame 10; in other words, the treatment couch can also improve the technical problem of low positioning precision of the patient in the prior art, and is not described herein again.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
