Description

Line placing device for outlining body surface positioning of tumor radiotherapy patient

Technical Field

The utility model relates to a device for outlining the body surface positioning line of a tumor radiotherapy patient, belonging to the technical field of medical instruments.

Background

The tumor poses great threat to the health of people all over the world, at present, malignant tumor is the second leading cause of death all over the world, the increase of the incidence rate of Chinese cancer is accelerated, in the years of 2007 and 2017, the incidence rate of Chinese cancer is increased by more than 2 percent year by year and exceeds the level of most countries, along with the rapid development of mathematics and physics, with the help of intelligent programs and imaging technologies, the radiotherapy technology is advanced from two dimensions to three dimensions, and then to the current four-dimensional radiotherapy technology, the radiation dose distribution received by patients is also developed from integral uniform distribution to volume dose distribution, and further the dose is intensified, the current radiotherapy technology can accurately concentrate the rays to the tumor tissue and avoid the radiation to the surrounding normal tissues, so as to achieve the accurate treatment effect of killing tumor cells to the maximum extent and protecting the normal tissues, but the tumor cycle of many tumor patients is relatively long clinically, the whole treatment process of a patient needs to be physically irradiated for many times to finish a treatment plan, radiation side reaction is not neglected, in the treatment process, the body type of the patient is easy to change (the change such as emaciation and the like are easy to occur in the treatment process of a tumor patient), and respiratory motion can cause the phenomenon that the actual treatment body position and the planned body position are inconsistent, the placing line introduced into the body surface of the patient can well help a radiotherapy doctor to place the patient, so that body position errors are reduced, however, the pen which is clinically used for the placing line and the treatment line at present is thicker and is inconsistent with the line thickness projected to the human body by the positioning of a radiotherapy machine, errors can occur in the process of correcting the body position, and the placing line and the treatment line are manually drawn by the doctor, because the human tissue is softer, even if instruments such as a ruler and the like are introduced, slight deflection is difficult to occur in the drawing process, the complete straightness cannot be guaranteed, and the projection line of the radiotherapy machine is complete straightness, so that errors can occur when the body position is corrected, and the radiotherapy precision is influenced.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to overcome the existing defects, and provide a device for outlining the body surface positioning line of a tumor radiotherapy patient, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme: the waterproof template comprises a waterproof template, wherein a guide mechanism is arranged in the middle of the front surface of the waterproof template, and pasting mechanisms are uniformly arranged on four sides of the rear surface of the waterproof template.

Further, the size of the waterproof template is 100 x 100 mm.

Furthermore, the guide mechanism comprises a transverse swing line and a vertical swing line, and the transverse swing line and the vertical swing line are arranged in the middle of the front surface of the waterproof template in a crossed manner.

Furthermore, the transverse swing line and the vertical swing line are both hollow structures.

Furthermore, the length of the transverse swing line and the vertical swing line is 80mm, and the width of the transverse swing line and the vertical swing line is 1 mm.

Further, the pasting mechanism comprises a pasting layer and release paper, the pasting layer is uniformly arranged on four sides of the rear surface of the waterproof template, and the release paper is arranged on the rear surface of the pasting layer.

The utility model has the beneficial effects that:

1. the guiding mechanism who sets up is the fretwork type structure rather than the inside part that includes, horizontal pendulum position line and vertical pendulum position line, can make the pendulum position line thickness that draws match the laser line width of radiotherapy machine completely to can guarantee that the fixed pendulum position line that the doctor drawn is in straight state, so that it and laser line coincide completely, furthest reduces patient's pendulum position error, reduces the radiation side reaction, increases the radiotherapy precision.

2. The sticking mechanism and the parts included in the sticking mechanism prevent the prepreg from being adhered, the prepreg can be protected from being polluted, and the sticking layer is non-setting adhesive (non-toxic, harmless and not easy to be allergic) and is used for sticking skin, so that the sticking of the waterproof template and the part of a patient needing treatment is firmer.
