Description

Radiotherapy web position determining device

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a device for determining the swing position of a web plate in radiotherapy.

Background

Radiotherapy treatment techniques require the use of a web during application. Because the machine for radiotherapy is not completely matched with the web used by the patient, a certain positioning error exists in the positioning of the radiotherapy patient before treatment, and the relative position of the patient and the web cannot be accurately repeated in multiple treatments, namely the body position of the patient during treatment is inconsistent with the body position during initial positioning, so that the treatment effect of the patient is finally influenced.

Therefore, how to correctly position the position of the web plate in radiotherapy of a patient is a problem which needs to be solved at present.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a device for determining the placement of a web plate in radiotherapy, which is used for improving the placement accuracy of the web plate in the radiotherapy of a patient.

In order to achieve the above purposes, the utility model provides a device for determining the placement of a web plate in radiotherapy, which comprises a chest belt and a bottom plate; the chest belt is detachably fixed on the bottom plate by connecting the first connecting piece and the second connecting piece; the web is mounted on the base plate. After the chest area was worn to the patient, lying prone on the bottom plate, the second connecting piece on the bottom plate is connected to through the first connecting piece location on the chest area, and the stop that patient's belly can be accurate this moment is on the web.

In one possible implementation manner, the first connecting piece comprises a side plate and two T-shaped buckles connected to the first side of the side plate; the second connecting piece comprises two T-shaped clamping grooves matched with the T-shaped buckles. Every side sets up two T font buckles for the connection of chest area and bottom plate is more firm, and the patient is difficult to take place to shift when lying prone on the bottom plate.

In a possible implementation manner, first sliding grooves are formed in two sides of the bottom plate, and a base of the second connecting piece protrudes downwards to form a protruding block to be inserted into the first sliding grooves; the edge faces of two sides of the bottom plate are provided with second sliding grooves, the protruding block is provided with a bolt, a screw rod of the bolt penetrates through the protruding block and the second sliding grooves, and a nut of the bolt is arranged outside the second sliding grooves. Because different patient's chest is different to abdominal distance, can adjust the position of second connecting piece on the bottom plate from beginning to end through the structure of this scheme to match different patient's chest abdomen distance, all can aim at the web with the belly when making different patients lie prone on this bottom plate.

In one possible implementation, the chest bands include a first chest band, a second chest band, and a third chest band; a first chest strap is arranged on the second side of the side plate; the top surfaces of the side plates of the two first connecting pieces are respectively provided with a second chest belt and a third chest belt; the second chest strap and the third chest strap are adjustably connected. The wearing of the chest strap on the chest of the patient is achieved by the connection of the second chest strap and the third chest strap.

In a possible implementation mode, the bottom plate is further provided with a leg fixing buckle, and the thigh of the patient is fixed through the leg fixing buckle, so that the possibility of displacement of the patient when the patient lies prone on the bottom plate is reduced.

Detailed Description

The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the utility model, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

Referring to fig. 1 of the drawings, fig. 1 is a schematic diagram of a radiotherapy web positioning determination device provided by the utility model, and as shown in fig. 1, the radiotherapy web positioning determination device comprises a chest belt 2 and a base plate 1; the two sides of the chest belt 2 are provided with first connecting pieces 21, the two sides of the bottom plate 1 are provided with second connecting pieces 11, and the chest belt 2 is detachably fixed on the bottom plate 1 by being connected with the second connecting pieces 11 through the first connecting pieces 21; the web 3 is mounted on the base plate. After the chest area was worn to the patient, lying prone on the bottom plate, the second connecting piece on the bottom plate is connected to through the first connecting piece location on the chest area, and the stop that patient's belly can be accurate this moment is on the web.

Fig. 2 is a schematic view of a chest strap provided by the present invention, as shown in fig. 2, in a possible implementation, the first connecting member 21 includes a side plate 211 and two T-shaped buckles 212 connected to a first side of the side plate 211; the second connecting piece 11 comprises two T-shaped clamping grooves matched with the T-shaped buckles. Every side sets up two T font buckles for the connection of chest area and bottom plate is more firm, and the patient is difficult to take place to shift when lying prone on the bottom plate.

In a possible implementation manner, first sliding grooves 41 are formed in two sides of the bottom plate, and a base of the second connecting member protrudes downwards to form a protruding block to be inserted into the first sliding grooves 41; the edge faces of two sides of the bottom plate are provided with second sliding grooves 42, the protruding block is provided with a bolt 5, a screw rod of the bolt 5 penetrates through the protruding block and the second sliding grooves 42, and a nut of the bolt is arranged outside the second sliding grooves 42. Because different patient's chest is different to abdominal distance, can adjust the position of second connecting piece on the bottom plate from beginning to end through the structure of this scheme to match different patient's chest abdomen distance, all can aim at the web with the belly when making different patients lie prone on this bottom plate.

In one possible implementation, the chest bands include a first chest band 221, a second chest band 222, and a third chest band 223; a first chest strap 221 is arranged on the second side of the side plate 211; the top surfaces of the side plates of the two first connecting pieces are respectively provided with a second chest strap 222 and a third chest strap 223; the second chest strap 222 and the third chest strap 223 are adjustably connected.
