Description

Technical Field

[0001] The invention relates to the technical field of tumor radiotherapy equipment, and in particular to a radiotherapy positioning table for tumor radiotherapy. Background Art

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. Tumor radiotherapy generally requires a special treatment machine for radiotherapy. During radiotherapy, the patient needs to lie on a special treatment table and fix the position. When fixing the patient's position, multiple medical staff are required to position the head, neck and shoulder membrane, body membrane, or vacuum pad. When the patient is injured or has difficulty holding up his body, multiple medical staff are required to cooperate in moving the patient. Therefore, this fixation method increases the labor intensity of medical staff and brings inconvenience to patients. Summary of the invention

[0003] The present invention provides a radiotherapy positioning table for tumor radiotherapy. The corresponding inflatable support strips are selected for inflation through an inflation control unit. A groove is formed on a main table plate under the action of the inflatable support strips. The patient is then tightened in the groove through a torso positioning membrane, thereby completing the final positioning of the patient's body. The operation can be performed by only one medical staff member, thereby greatly saving manpower and improving work efficiency.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a radiotherapy positioning table for tumor radiotherapy, comprising: a main table plate, which is a horizontally arranged rectangular sandwich plate structure, and the main table plate is installed on the top of the motion platform for carrying the patient; a shoulder slide plate, which is arranged on the top of the main table plate through an adjustment mechanism and corresponds to the patient's shoulders and head; a plurality of first positioning holes are provided on the top of the shoulder slide plate for installing and fixing the head, neck and shoulder positioning membrane; a plurality of second positioning holes arranged in a matrix are provided on the top of the main table plate for installing and fixing the torso positioning membrane; inflatable support strips are respectively provided on both sides of the main table plate corresponding to the patient's torso; the inflatable support strips are connected to the inflation control unit through pipelines.

[0005] Preferably, it also includes an auxiliary support airbag, which is arranged on the top of the main platform corresponding to the patient's legs, and the auxiliary support airbag is connected to the inflation control unit.

[0006] Preferably, the inflatable support strip and the bottom of the auxiliary support airbag are both provided with connecting plates, and the bottom of each connecting plate is provided with a plurality of rubber-coated plugs adapted to the second positioning holes.

[0007] Preferably, the main table plate includes a top sterile plate, a bottom high-strength plate, and a locking plate corresponding to the patient's torso and horizontally movably arranged between the sterile plate and the high-strength plate; a plurality of support blocks are arranged between the high-strength plate and the sterile plate, and the second positioning holes sequentially penetrate the sterile plate, the locking plate and the high-strength plate, the locking plate is provided with a penetrating rectangular sliding hole corresponding to each of the support blocks, and a locking handle connected to the locking plate is provided on the outside of the main table plate; a locking groove is provided on the outer wall of the rubber-coated plug corresponding to the locking plate.

[0008] Preferably, the main platform is provided with circular grooves corresponding to the patient's shoulder and head areas, the adjustment mechanism includes a main shaft vertically arranged in the circular groove, and a planar thrust bearing surrounding the main shaft, a sleeve matching the main shaft is provided at the bottom of the shoulder slide plate, and an adjustment handle is provided on the side of the shoulder slide plate away from the main platform.

[0009] Preferably, a plurality of positioning grooves are provided at the bottom of the shoulder slide plate, and the positioning grooves are arranged circumferentially around the sleeve at intervals. Marbles are provided in the circular grooves, and the marbles correspond to any one of the positioning grooves.

[0010] The beneficial effect of the present invention is that when the patient lies on the main platform, the medical staff preliminarily adjusts the patient's body position, fixes the patient's shoulders, neck and head on the shoulder slide plate through the head, neck and shoulder positioning membrane, and then fine-tunes the patient's shoulder tilt angle through the adjustment mechanism, and then fixes the patient's body through the trunk positioning membrane. In order to achieve a stable effect, the corresponding inflatable support strip is selected by the inflation control unit for inflation, and a groove effect is formed on the main platform under the action of the inflatable support strip, and then the patient is tightened in the groove through the trunk positioning membrane, thereby completing the final positioning of the patient's body. This operation only needs to be performed by one medical staff, which greatly saves manpower and improves work efficiency. In some special body positions, the auxiliary support airbag can shape the patient's legs, arms, and even head to meet different body position fixation requirements. After the rubber-coated plug is inserted into the second positioning hole, the relative position of the locking plate is changed by operating the locking handle, so that a misaligned hole is generated in the second positioning hole, and the locking groove of the rubber-coated head is locked under the offset of the locking plate, thereby avoiding the problem that the trunk positioning membrane pops out of the second positioning hole due to elastic tension, resulting in failure of fixation of the patient's body. The angle adjustment of the shoulder slide is facilitated by adjusting the handle, and the plane thrust bearing reduces the adjustment resistance of the shoulder slide. Through the cooperation of the marble and the positioning groove, the angle adjustment of the edge shoulder slide is self-locking. BRIEF DESCRIPTION OF THE DRAWINGS
