Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a radiotherapy positioning ruler. Background Art

[0002] Radiotherapy is a treatment method that uses particle radiation to kill or inhibit the growth of cancer cells. Accurate patient positioning is crucial during radiotherapy. Radiotherapy techniques include stereotactic technology and image guidance technology, which use radiological images to guide treatment equipment to accurately irradiate patients. Radiotherapy positioning rulers are used as auxiliary tools to help medical staff accurately locate and adjust the patient's position to ensure the accuracy and safety of radiotherapy. However, in the existing technology, during the line drawing process, the marker pen and the hand drawing the line will block the laser cross line, making the laser cross line projection discontinuous. Under this condition, the drawn positioning mark line will be offset, affecting the positioning accuracy, and thus affecting the effect of radiotherapy. Utility Model Content

[0003] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0004] A radiotherapy positioning ruler comprises a plate body, characterized in that a plurality of groups of measuring grooves are provided on the surface of the plate body, and marking components are fixedly installed in the measuring grooves.

[0005] Furthermore, the marking assembly includes a pen holder and a pen tip, wherein the pen holder is fixedly mounted at the bottom of the measuring slot, and the pen tip is fixedly mounted inside the pen holder.

[0006] Furthermore, the measuring groove is opened in a cross shape on the plate body, and the measuring groove runs through the top and bottom of the plate body.

[0007] Furthermore, a plurality of scale bars are engraved beside the measuring groove, and digital marks are engraved beside the plurality of scale bars.

[0008] Furthermore, a plurality of the measuring grooves are configured with alignment grooves at ends away from the center of the plate body, and the alignment grooves are arranged at the center line of the measuring grooves.

[0009] Furthermore, the plate body is provided with arc transitions on all four sides.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The utility model provides a marking component at the bottom of the measuring slot, so that when the plate is moving, the marking component can be used to mark and draw lines on the patient's body, thereby solving the problem that the hand will block the laser cross line when drawing lines, causing the laser cross line to be discontinuously projected.

[0012] 2. The utility model provides a plurality of alignment grooves at the end of the measuring groove far from the center of the plate body, so that when the plate body is moved, the alignment process can be performed by observing the position where the laser shines on the plate body, thereby further improving the accuracy.

[0013] 3. The utility model adopts arc transition around the plate body, thereby avoiding the situation where the plate body is too sharp and causes scratches on the patient's body and causes injuries. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] The present application provides a radiotherapy positioning ruler, which is mainly used to solve the problem that during the line drawing process, the marking pen and the hand drawing the line will block the laser cross line, making the laser cross line projection discontinuous. Under this condition, the drawn positioning mark line will be offset, affecting the positioning accuracy, and further affecting the radiotherapy effect. The following technical solutions are provided. Figure 1-Figure 3 Make a detailed description:

[0020] A radiotherapy positioning ruler comprises a plate body 1, a plurality of measuring grooves 2 are provided on the surface of the plate body 1, a marking assembly 3 is fixedly installed in the measuring groove 2, the marking assembly 3 comprises a pen holder 301 and a pen tip 302, the pen holder 301 is fixedly installed in the bottom of the measuring groove 2, the pen tip 302 is fixedly installed in the pen holder 301, the measuring groove 2 is cross-shaped and provided on the plate body 1, the measuring groove 2 runs through the top and the bottom of the plate body 1, a plurality of scale bars 4 are engraved beside the measuring groove 2, a plurality of scale bars 4 are engraved beside each of the plurality of scale bars 4, an alignment groove 6 is constructed at the end portions away from the center of the plate body 1, the alignment groove 6 is provided at the center line position of the measuring groove 2, an arc transition is adopted around the plate body 1, in some embodiments, when the laser cross line is projected on the patient's body, the plate body 1 is first placed on the surface of the patient's body, the pen tip 302 is in contact with the patient's body, and then the alignment groove 6 is observed because the alignment groove 6 is provided in the measuring groove 2. Center position, align the alignment grooves 6 at both ends with the laser, and then slowly move the plate 1. Since the pen holder 301 is fixedly installed at the bottom of the measuring groove 2 and is located in the center, the pen tip 302 will draw a line on the patient's body surface.
