Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a PET-CT imaging positioning device. Background Art

[0002] PET-CT integrates PET and CT. PET provides detailed molecular information on the function and metabolism of lesions, while CT provides precise anatomical localization of lesions. A single scan can produce full-body cross-sectional images from all angles. Its sensitivity, accuracy, specificity, and precise positioning provide a clear overview of the entire body, enabling early detection of lesions and diagnosis of diseases. PET-CT, a fusion of the highest-end PET scanners and advanced spiral CT equipment, is primarily used clinically for the early detection and diagnosis of major diseases in areas such as tumors, brain, and heart disease.

[0003] When using existing technology for PET-CT examination, there is no precise positioning mark on the patient's body. Medical staff cannot accurately restore the position and size information of the patient's body. Before puncture, they cannot accurately determine the location of the puncture point, the direction of needle insertion and the depth, which can easily cause deviations in subsequent puncture biopsy. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A PET-CT imaging positioning device, used for PET-CT detection, includes a carrier layer, a top surface of which is provided with a plurality of longitudinal positioning lines and a transverse positioning line, and a plurality of positioning holes are provided at the intersections of the longitudinal positioning lines and the transverse positioning lines;

[0007] A plurality of positioning balls are installed in the plurality of positioning holes, and the plurality of positioning balls are evenly arranged along the longitudinal positioning line and the transverse positioning line. An accommodating cavity is provided inside the positioning balls, and an oily substance for absorbing radiation is provided in the accommodating cavity.

[0008] Based on the above technical solution, its use principle and the technical effects produced are as follows:

[0009] When auxiliary positioning is needed, first tear off the protective film, and use the adhesive layer to stick the supporting layer and the positioning ball to the patient's scanning part. Since there is a accommodating cavity inside the positioning ball, cod liver oil is set in the accommodating cavity. The cod liver oil can absorb radiation, so it can produce multiple evenly arranged point artifacts, specifically white bright spots. By using the unit length between adjacent white bright spots, a certain part of the patient can be accurately measured, which is convenient for subsequent puncture positioning.

[0010] In a preferred example, the present invention can be further configured as follows: the bearing layer is made of non-woven fabric, a viscose layer is provided below the bearing layer, and the positioning balls are arranged through the viscose layer.

[0011] In a preferred example, the present invention can be further configured as follows: the positioning ball is fixed in the positioning hole by medical glue, and the material of the positioning ball is set to be plastic.

[0012] In a preferred example, the present invention can be further configured as follows: the positioning ball is shaped as a sphere, and the diameter of the positioning ball is 4-5 mm.

[0013] In a preferred example, the present invention can be further configured as follows: the positioning ball is shaped as an ellipsoid, and the long diameter of the positioning ball is 4-5 mm, and the short diameter is 2-4 mm.

[0014] In a preferred example, the present invention can be further configured as follows: the adhesive layer is made of medical adhesive, a protective film is provided on the outer surface of the adhesive layer, and the positioning ball is arranged through the protective film.

[0016] In a preferred example, the present invention can be further configured as follows: adjacent longitudinal positioning lines or adjacent transverse positioning lines are spaced at least one unit length apart.

[0017] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0018] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0019] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0020] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting when repairing or replacing, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to the quality of workmanship, technical inspection and remedial measures (such as calibration, polishing, etc.);

[0021] An active connection is a connection in which parts or components are fixed so that they can move relative to each other.

[0022] The above technical solution of the present utility model has the following beneficial technical effects:

[0023] In the present invention, through the mutual cooperation of the supporting layer, positioning ball, accommodating cavity, oily substance and other structures, a plurality of evenly arranged point-like artifacts can be generated, specifically white bright spots. By using the unit length between adjacent white bright spots, a certain part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.

[0029] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other in the absence of conflict.

[0030] Example 1:

[0031] According to the concept of this application, Figures 1 to 2 The following describes an embodiment of a PET-CT imaging positioning device for PET-CT examinations. Specifically, the PET-CT imaging positioning device is constructed as an integrated structure, comprising four components: a carrier layer 1, a positioning ball 5, an adhesive layer 6, and a protective film 7. The coordination of the carrier layer 1, positioning ball 5, accommodating cavity 9, and oily substance 10 produces multiple evenly spaced point artifacts, specifically white bright spots. Using the unit length between adjacent white bright spots, a specific part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.

[0032] Combine Figure 1-2As shown, the present invention provides a PET-CT imaging positioning device, which is applied to PET-CT detection, comprising a carrier layer 1, wherein a top surface of the carrier layer 1 is provided with a plurality of longitudinal positioning lines 2 and a transverse positioning line 3, and a plurality of positioning holes 4 are provided at the intersections of the longitudinal positioning lines 2 and the transverse positioning lines 3;

[0033] A plurality of positioning balls 5 are installed in the plurality of positioning holes 4, and the plurality of positioning balls 5 are evenly arranged along the longitudinal positioning line 2 and the transverse positioning line 3. An accommodating cavity 9 is provided inside the positioning ball 5, and an oily substance 10 for absorbing radiation is provided in the accommodating cavity 9.

[0034] According to the technical solution of this embodiment, the supporting layer 1 is made of non-woven fabric, a viscose layer 6 is arranged under the supporting layer 1, and the positioning ball 5 is arranged through the viscose layer 6. The supporting layer 1 can provide support for the positioning ball 5, and the viscose layer 6 can be used to facilitate the adhesion of the device to the part of the patient to be tested.

[0035] PET-CT integrates PET and CT. PET provides detailed molecular information such as the function and metabolism of lesions, while CT provides precise anatomical positioning of lesions. A single imaging scan can obtain tomographic images of the entire body from all directions. It is sensitive, accurate, specific, and has precise positioning. It allows users to understand the overall condition of the body at a glance, achieving the purpose of early detection of lesions and diagnosis of diseases.

[0036] PET-CT provides much more predictive and therapeutic information than PET and CT alone, and it goes beyond the existing scope of PET and CT alone. It can perform all the functions of ultra-high-end CT and the functions of PET - a whole-body CT scan can be completed in 20 minutes, which is more than 60% more efficient than simple PET. It can also provide more accurate and faster functional images of myocardial and cerebral blood perfusion than CT. PET-CT fusion images can well describe the effect of the disease on biochemical processes, distinguish between physiological and pathological uptake, detect early signs of the disease before anatomical evidence is obtained, and even detect subclinical tumors smaller than 2mm. It provides the best treatment plan and screening of the most effective therapeutic drugs for the correct clinical determination of the planned target area for radiotherapy (combination of clinical target area and biological target area), detection of drug and radiotherapy effects during treatment, and anatomical positioning plus functional imaging for the lesion site.

[0037] According to the technical solution of this embodiment, the material of the positioning ball 5 is set to plastic, and the oily substance 10 is set to cod liver oil. When performing PET-CT detection, since a accommodating cavity 9 is opened inside the positioning ball 5, and cod liver oil is set in the accommodating cavity 9, the cod liver oil can absorb radiation, thereby generating multiple evenly arranged point artifacts, specifically white bright spots. By using the unit length between adjacent white bright spots, a certain part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.

[0038] According to the technical solution of this embodiment, the shape of the positioning ball 5 is set to be spherical, and the diameter of the positioning ball 5 is 4-5 mm.

[0039] According to the technical solution of this embodiment, the adhesive layer 6 is made of medical glue 8, and a protective film 7 is provided on the outer surface of the adhesive layer 6. The protective film 7 is made of a thin film material. The positioning ball 5 is arranged through the protective film 7, and the protective film 7 is used to protect the adhesive layer 6.

[0040] There is at least one unit length between adjacent longitudinal positioning lines 2 or adjacent transverse positioning lines 3. This embodiment does not limit this. The unit length between the longitudinal positioning lines 2 or the transverse positioning lines 3 can be adjusted according to actual needs. The unit length is also not limited here and can be selected according to actual needs. For example, one unit length is 1CM.

[0041] It should be noted that the size of the PET-CT imaging positioning device is not limited here and can be cut according to specific parts.

[0042] Specifically, when auxiliary positioning is needed, first tear off the protective film 7, and use the adhesive layer 6 to stick the supporting layer 1 and the positioning ball 5 to the scanning part of the patient. Since the positioning ball 5 has a receiving cavity 9 inside, cod liver oil is provided in the receiving cavity 9. The cod liver oil can absorb radiation, so it can produce multiple evenly arranged point artifacts, specifically white bright spots. By using the unit length between adjacent white bright spots, a certain part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.

[0043] The following further describes a PET-CT imaging positioning device provided by the present invention in conjunction with the accompanying drawings and implementation examples.

[0044] A PET-CT imaging positioning device, used for PET-CT detection, comprises a carrier layer 1, a top surface of which is provided with a plurality of longitudinal positioning lines 2 and a transverse positioning line 3, and a plurality of positioning holes 4 are provided at the intersections of the longitudinal positioning lines 2 and the transverse positioning lines 3;

[0045] A plurality of positioning balls 5 are installed in the plurality of positioning holes 4, and the plurality of positioning balls 5 are evenly arranged along the longitudinal positioning line 2 and the transverse positioning line 3. An accommodating cavity 9 is provided inside the positioning ball 5, and an oily substance 10 for absorbing radiation is provided in the accommodating cavity 9.

[0046] Example 2:

[0047] Combine Figure 3 As shown, the fundamental difference between Example 2 and Example 1 is that the shape of the positioning ball 5 is set to be an ellipsoidal sphere, and the long diameter of the positioning ball 5 is 4-5mm, and the short diameter is 2-4mm. The ellipsoidal positioning ball 5 is easier to fix in the positioning hole 4 than the spherical one.

[0048] Example 3:

[0049] The fundamental difference between Example 3 and Example 1 is that the positioning ball 5 is fixed to the outside of the supporting layer 1 by medical glue 8 and does not penetrate the supporting layer 1, and the positioning ball 5 is located at the intersection of the longitudinal positioning line 2 and the horizontal positioning line 3. Compared with Example 1, this embodiment can save production processes and improve production efficiency during the production process.

[0050] The working principle and usage process of the present invention are as follows: when auxiliary positioning is required, the protective film 7 is first torn off, and the supporting layer 1 and the positioning ball 5 are pasted to the scanning part of the patient using the adhesive layer 6. Since a receiving cavity 9 is provided inside the positioning ball 5, cod liver oil is provided in the receiving cavity 9. The cod liver oil can absorb radiation, and thus can produce multiple evenly distributed point-shaped artifacts, specifically white bright spots. By using the unit length between adjacent white bright spots, a certain part of the patient can be accurately measured, thereby facilitating subsequent puncture positioning.
