Problems solved by technology

[0004] Aiming at the deficiencies and problems of patient position fixation in the existing chest tumor radiotherapy process, the present invention provides a body position fixation device for heavy ion radiotherapy of chest tumors. There is a time difference in side pushing, which leads to the problem that the vacuum negative pressure pad cannot be effectively attached to the skin of the patient's back, and it also effectively solves the problem that the vacuum pad and thermoplastic film cannot be fully exerted in the prior art.

Embodiment 1

[0041] When the patient is fixed in position before radiotherapy, the operator needs to manually push the edges of the vacuum pad on both sides of the patient to make it fit the patient's body. However, because the vacuum pad is continuously pumped for shaping , so that when the operator pushes the edge of the other side of the vacuum pad after the edge of the vacuum pad on one side is pushed, the vacuum pad will be hardened due to the suction of the vacuum pad, resulting in another vacuum pad. One side edge cannot be pushed and contacted effectively with the patient's body, which will lead to increased errors due to the patient's inability to restrain the back during repetitive operations, reducing the accuracy of positioning; and the vacuum pad and thermoplastic body in the prior art The matching and use of the film is operated separately from the individual, which cannot effectively fully exert the matching and fixing effect of the vacuum pad and the thermoplastic film.

Embodiment 2

[0056] The difference between Embodiment 2 and Embodiment 1 is that there is a torsion spring between the shaft sleeve and the fixed shaft. The torsion spring will drive the shaft sleeve to rotate outward around the fixed shaft in a natural state, so that the top end of the arc-shaped driving rod is supported by the upper part. The bottom surface of the plate touches the top, so that after the radiotherapy treatment is completed, the air bag support is inflated to restore the distance between the upper and lower support plates. Easy to remove vacuum pad and thermoplastic body film.

Embodiment 3

[0058] The difference between Example 3 and Example 2 is that, as image 3 As shown in the figure, a receiving groove 12 is vertically opened at the position where the back support frame is installed on the radiotherapy bed. The shape of the receiving groove 12 matches the shape of the back support frame, and the four sliding holes are all opened at the bottom of the receiving groove. The accommodating groove 12 is provided, which can effectively reduce the height of the back support frame protruding from the surface of the radiotherapy table and increase the comfort of the patient lying flat.

Abstract

A body position fixing device for chest tumor heavy ion radiotherapy disclosed by the present invention comprises a radiotherapy bed, a vacuum pad and a thermoplastic body film, frames are fixed on the left and right sides of the thermoplastic body film, a back support frame is installed on the radiotherapy bed in a matching manner, the back support frame comprises three support plates which are arranged in parallel at intervals from top to bottom, and the three support plates are connected with the vacuum pad. The vacuum pad is installed on the top layer supporting plate in a matched mode in the longitudinal direction, supporting and pressing mechanisms are installed on the middle layer supporting plate and the bottom layer supporting plate in a matched mode, and each supporting and pressing mechanism comprises an air bag supporting piece and a clamping arm set. The device is unique in structure, the problem that the vacuum negative pressure pad cannot be effectively attached to the skin of the back of a patient due to the fact that time difference exists between pushing of the two sides of the vacuum negative pressure pad can be effectively solved, and the problem that in the prior art, the matching and fixing effect of the vacuum pad and the thermoplastic body film cannot be completely achieved is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a body position fixing device for heavy ion radiotherapy of chest tumors. Background technique [0002] Tumor radiation therapy is a local treatment method that uses radiation to treat tumors. Radiation includes alpha, beta, and gamma rays produced by radioisotopes and x-rays, electron rays, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients require radiation therapy during the treatment of cancer, and about 40% of cancers can be cured with radiation therapy. The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors. With the development and progress of science and technology, heavy ion radiotherapy technology has emerged as the times require. This treatment method does little damage ...
