Description

Technical Field

[0001] The utility model belongs to the field of medical equipment planning, in particular to a leg-part body membrane for radiotherapy treatment. Background Art

[0002] Radiation therapy is one of the three main methods of cancer treatment. Its fundamental goal is to maximize tumor destruction, increase local tumor control, and reduce the probability of radiation complications in surrounding normal tissues. In the entire radiotherapy process, body fixation is the first step, and the production of body fixation devices is particularly important for precise positioning. Lying boards and body membranes are commonly used positioning methods in treatment. While ensuring patient comfort, they limit patient movement during treatment, minimize radiotherapy positioning errors and organ motion errors, and thus improve radiotherapy accuracy. However, when patients need to receive radiotherapy in the lithotomy position, the traditional lying boards and body membranes used to fix the patient's body cannot achieve good fixation. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a leg-type body membrane for radiotherapy treatment, which solves the problem that when the patient needs to be in the lithotomy position for radiotherapy, the traditional lying board and body membrane used to fix the patient's body cannot be fixed well.

[0004] The technical solution is that the leg-type body membrane for radiotherapy treatment includes a lying plate for radiotherapy positioning, a fixing bar and a membrane body constituting a radiotherapy mold, the edge of the lying plate is provided with a movable support column, the support column has two and is symmetrically arranged about the midline of the lying plate, and the lying plate is provided with a long slot for the support column to move, the long slot includes an empty slot extending from the edge of the lying plate to its interior and a through slot located in the slide rail, the cross-section of the slide rail is a "U"-shaped structure, the slide rail is rotatably connected to the lying plate, forming a structure in which the slide rail is normally arranged along the length direction of the lying plate, and is rotated to a structure perpendicular to the lying plate when in use, the support column is a "Y"-shaped structure, and the end of the support column away from the lying plate is provided with a thigh support and a calf support, and the thigh support and the calf support are provided with a leg membrane for fixing the patient's leg, and the thigh support and the calf support are provided with fixing holes on both edges along their respective length directions, and the leg membrane is provided with a fixing bar used in conjunction with the fixing hole, so that a structure that relies on the thigh support, the calf support and the leg membrane to restrain the patient's legs and fix the patient in the lithotomy position during radiotherapy is formed.

[0005] Preferably, the slide rail includes an upper plate and a lower plate, the cross-sections of the upper plate and the lower plate are both "L"-shaped, the upper plate and the lower plate are both rotatably connected to the lying plate through a torsion spring, and the upper plate is provided with an end plate connected to the lower plate.

[0006] Preferably, a slide groove is provided in the long groove, and a sliding end is provided at one end of the support column for use with the slide groove. The cross-section of the sliding end is a "convex"-shaped structure. A card slot is provided in the long groove. There are multiple card slots and they are evenly spaced along the length direction of the slide groove. An elastic protrusion is provided on the sliding end for use with the card slot.

[0007] Preferably, the support column is rotatably connected to the end away from the lying board with a disc, and the disc is provided with a limiting hole running through the thickness direction thereof, and there are multiple limiting holes which are centrally symmetrically arranged about the center of the disc. The support column is provided with an insert column, forming a structure for fixing the rotation angle of the disc after the insert column is inserted into the limiting hole, and the thigh support and the calf support are both fixed with the disc screws.

[0009] The beneficial effect of the utility model is that a movable support column is arranged on the lying board, and the end of the support column is provided with a thigh support and a calf support for supporting the patient's legs. The width of the thigh support and the calf support can be adjusted according to the actual situation of the patient, and the patient's legs are fixed under the action of the fixing strip and the membrane, and the patient is confined to the lithotomy position to ensure the radiotherapy treatment effect;

[0010] The arrangement of the slide rail and its internal through groove, and the cooperation with the empty groove to ensure the length of the long groove, is convenient for use by patients of different body shapes. The arrangement of the sliding end on the support column facilitates movement in the slide groove. The arrangement of the elastic protrusion on the support column facilitates the cooperation with the clamping groove in the long groove to limit the position of the support column in the long groove.
