Embodiment 1

[0052] Embodiment 1: A kind of device for turning chest in prone position

[0053] Considering the comfort of the patient, the basic support structure of the bed frame 1 is adopted. The bed frame 1 is only used for data acquisition, so we decided to adopt the bed frame 1 with a basic steel frame structure. In this way, the cost is lower, the function can be used, and it is relatively strong and stable.

[0054] One end of the bed frame 1 is provided with a headboard 2, and the front side of the bed frame 1 close to the headboard 2 is provided with an installation window, and the installation window is arranged at the approximate front 1 / 3 position of the bed body. Chest position after lying down.

[0055] A box body 3 is fixed in the installation window, the top surface and the ground of the box body 3 are open structures, and the bottom opening of the box body 3 is provided with a hanging plate 5 that can be closed. The plate 5 and the box body 3 jointly form a cavity stru...

Embodiment 2

[0073] Embodiment 2: A method for making a patient's chest model using a prone chest model turning device according to Embodiment 1

[0074] When the above-mentioned device is actually used to sample and turn over the three-dimensional data of the patient's prone position, the specific method is as follows:

[0075] 1) Hang the hanging plate 5 on the bottom opening of the box body 3, so that the bottom of the box body 3 is closed as a concave cavity;

[0076] 2) Apply vaseline on the scraper and the inner wall of the box body 3 to prepare for demoulding;

[0077] 3) The patient's upper body is bare, and the upper body is smeared with Vaseline;

[0078] 4) Put the neck expansion ring 10 and the abdominal expansion ring 16 respectively on the corresponding positions of the neck and the abdomen. The expansion ring is a rubber airbag structure, which has telescopic ductility and is easy to insert. After being inserted, it is pre-inflated to make the expansion ring After the swel...

Embodiment 3

[0093] Embodiment 3 A kind of bending device for chest in prone position

[0094] The difference from Embodiment 1 is that in this example, the inflatable body we designed is arc-shaped. In terms of the design of the inflatable body, since the hospital has abundant inert gas resources, we prefer to use airbags. Softer with better control over swelling and squeezing.

[0095] In Embodiment 1, the expansion ring of the annular airbag structure is constrained by a detachable way, using hard stoppers that are relatively close together to form an annular member. Leakage is better. At the same time, each component is easy to disassemble quickly. The limit piece is stuck on the expansion ring, and the two are inserted into the semicircular or semi-elliptical groove together, and the limit piece is squeezed through the groove, and the limit piece squeezes the expansion ring, so that the expansion ring squeezes the neck of the human body , upper arm, and abdomen. Quick disassembly ...

Abstract

The invention discloses a bending-posture breast mold-turning device and a manufacturing method of a bending-posture breast three-dimensional curved surface model, and mainly relates to the field of radiotherapy auxiliary instruments. The device of the invention includes a bedstead, on which a mounting window is arranged. A box body is arranged on the mounting window. Both the bottom surface and the top surface of the box body are of an open structure. The bottom surface of the box body is detachably provided with a hanging plate for closing the opening of the box body. The front side of the box body is provided with a neck groove. The left and right sides of the box body are symmetrically provided with upper limb grooves. The rear side of the box body is provided with an abdominal groove.The groove bottoms of the neck groove, the upper limb groove and the abdominal groove are all flush with the upper surface of the bedstead. The neck groove, the upper limb groove and the abdominal groove are respectively provided with expansion bodies therein, and the expansion bodies can be filled with a gas or a liquid to expand. The expansion bodies are used for close contact with skin surfaces at corresponding positions of the human body. The invention has the beneficial effects as follows: the curved surface of the breast naturally falling and getting away from the bending-posture body can be obtained and cured, thus providing the curved surface basis for the manufacturing of radiotherapy treatment protective equipment.

Description

technical field [0001] The invention relates to the field of radiation therapy auxiliary equipment, in particular to a device for turning a breast in a prone position and a method for making a three-dimensional curved surface model of a breast in a prone position. Background technique [0002] In radiotherapy for breast cancer, in order to ensure that the target position of each treatment is accurate, it is usually necessary to carry out auxiliary fixation of the breast with the help of tools. The patient is then placed in a supine position for treatment. [0003] In existing clinical practice, the patient is allowed to solidify the curved surface of the breast and make a protective gear in a supine state. Because in other positions, the breast cannot be in a neutral position under the condition of gravity. However, in the prone position, existing devices and techniques cannot keep the breast in a sagging state at the bottom for sampling. Contents of the invention [00...
