DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be combined with the drawings and examples, and the utility model will be further described in detail. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0031] When the puncture needle is punctured into the lesion, the gold standard needs to be loaded into the puncture needle, and then the gold standard is pushed into the body by the push rod for positioning. In order to be convenient to hold, a thicker handle is arranged at the rear end of the puncture needle, and the connection between the handle and the puncture needle presents a tapered transition, the inner diameter of the upper part is larger, and the inner diameter of the lower part is smaller, which are uniformly transitioned. Since the gold standard is very small, generally with a diameter of 0.8 mm and a length of 4.5 mm, in the process of entering the puncture needle through the handle, the gold standard is easy to be stuck in the transition between the handle and the puncture needle once it rotates, and needs to be repeatedly adjusted to be successfully loaded, which is time-consuming and laborious.

[0032] In order to solve the above problems, the utility model provides a kind of gold standard loader for radiotherapy positioning, as shown in the figure, including handheld base 1, and handheld base 1 upper part is provided with loading device 2 and positioning device 3, and lower part is provided with guide nozzle 4. Figure 1 As shown in the figure, loading device 2 includes loading body 21 and cover 22. As shown in the figure, the cross section of loading body 21 is regular hexagon, and handheld base 1 is provided with rotary shaft 23, and is specifically arranged on the side of the top surface of handheld base 1, and is arranged vertically to the top surface. Loading body 21 is installed on rotary shaft 23 and can rotate along rotary shaft 23. As shown in the figure,

[0033] Figure 1 Figure 2 Figure 3 ​​​As shown, the loading body 21 is provided with a receiving cavity 24, which extends through the height of the loading body 21. The diameter of the receiving cavity 24 is slightly larger than the diameter of the gold mark. Generally, the loading body 21 is provided with three receiving cavities 24, evenly distributed along the circumference of the loading body 21. The cover 22 is provided on the upper side of the loading body 21 and is fixedly connected to the rotating shaft 23. The cover 22 is provided with a through hole 25, which is arranged directly opposite the guide nozzle 4.

[0034] like Figure 3 As shown, the positioning device 3 is provided on one side of the loading device 2 and is fixedly connected to the handheld base 1. The positioning device 3 is provided with a blind hole 31 perpendicular to the side of the loading body 21. A fixing post 32 is provided in the blind hole 31, and a spring 33 is provided between the fixing post 32 and the blind hole 31. Since the blind hole 31 is provided directly opposite the side of the loading body 21 and the fixing post 32 is cylindrical, when the fixing post 32 is directly opposite the side of the loading body 21, the fixing post 32 and the loading body 21 can be relatively fixed due to the action of the spring 33. When the loading body 21 is rotated with force, the spring 33 is compressed, as shown in FIG. Figure 6 As shown, until the fixing post 32 faces the next side surface of the loading body 21, the fixing post 32 and the loading body 21 can be relatively fixed again.

[0035] When the positioning device 3 is positioned relative to a side surface of the loading body 21, the accommodating cavity 24 is positioned directly opposite the through-hole 25 and the guide nozzle 1. When the blind hole 31 is positioned directly opposite the centerline of the side surface of the loading body 21, the accommodating cavity 24 is also positioned directly opposite the centerline of the side surface of the loading body 21. When the accommodating cavity 24 is positioned directly opposite the through-hole 25 and the guide nozzle 4, the three interconnect, forming a passage for the gold mark 6 and the push rod 7.

[0036] Before the operation, the entire device is disinfected and then loaded with the gold label. The loading body 21 is rotated so that the accommodating cavity 24 is facing the through hole 25 on the cover 22, and then the gold label 6 is placed into the accommodating cavity 24 along the through hole 25. At this time, the loading body 21 is rotated so that the accommodating cavity 24 is not facing the through hole 25 and the guide nozzle 4, ensuring that the gold label 6 is kept in the accommodating cavity 24. When there are three accommodating cavities, the operation is the same. Figure 2 As shown, it is a schematic diagram of the gold label storage state, body 3 is Figure 2 The cross-sectional view shows that the accommodating cavity 24 is not aligned with the through hole 25 and the guide nozzle 4. Then insert the guide nozzle 4 into the handle of the puncture needle 5 and set it opposite to the puncture needle 5. Figure 8 As shown, after setting up, puncture can be performed. After puncture is in place, rotate the loading body 21, and when the side corresponding to the accommodating cavity 24 is rotated to face the fixing device, the fixing device 3 and the accommodating cavity 24 are relatively fixed, and the through hole 25, the accommodating cavity 24 and the guide nozzle 4 are facing each other and interpenetrating, as shown in FIG. Figure 4 The figure shows the state where the gold mark 6 is aligned and can be pushed out.Figure 5 For Figure 4 The cross-sectional view. At this time, the gold mark can be smoothly pushed to the desired location by the push rod along the through hole 25, such as Figure 7 As shown, the operation is convenient and saves time and effort.

[0037] The radiotherapy positioning gold mark loader can cooperate with the implantation of gold marks during the puncture process, and has the advantages of simple structure, convenient and smooth operation, time and labor saving, and avoidance of the situation that the gold mark is stuck in the puncture needle.

[0038] Further, as shown in Figure 1 , a gap is provided between the cover 22 and the loading body 21, which is about 1mm. This design is mainly to make the loading body 21 rotate smoothly and not jam.

[0039] Further, as shown in Figure 1 , the tip of the guide nozzle 4 is conical. The tip of the guide nozzle 4 is conical, mainly to match the structure of the handle of the puncture needle 5 and the connection between the puncture needle. This design can make the gold mark loader more stable when installed at the handle of the puncture needle 5, and facilitate the subsequent pushing of the gold mark into the body.

[0040] Further, as shown in Figure 1 , 2 and 3, the side of the loading body 21 is arc-shaped. The arc-shaped design makes the loading body 21 rotate smoothly and saves effort.

[0041] Further, as shown in Figure 2 and 4 , a recess is provided in the middle of the hand-held base 1, and a plurality of vertical raised lines are provided in the recess. The recess is provided for easy gripping, and the vertical raised lines are designed to prevent slipping when holding.

[0042] Further, the upper opening of the accommodating cavity 24 is trumpet-shaped, and the diameter of the upper opening of the accommodating cavity 24 is greater than that of the lower opening of the through hole 25. The upper opening of the guide nozzle 4 is also trumpet-shaped, and the diameter of the upper opening of the guide nozzle 4 is greater than that of the lower opening of the accommodating cavity 24. When the through hole 25, the accommodating cavity 24 and the guide nozzle 4 are opposite, the gold mark 6 can be pushed into the body by the push rod 7. Since the gold mark 6 is small, it is easy to jam at the connection between the two components, and the above design avoids this situation and ensures smoothness during the gold mark pushing process.

[0043] Further, as shown in Figure 3 , the upper opening of the through hole 25 is also trumpet-shaped, which facilitates the loading of the gold mark 6.

[0044] It should be understood that modifications or variations can be made according to the above description by those of ordinary skill in the art, and all such modifications and variations are intended to be within the scope of the present application as defined by the claims appended hereto.
