Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a CyberKnife positioning gold label patch bag. Background Art

[0002] Gold label implantation is an important step in CyberKnife treatment of tumors of motor organs (such as lung cancer, liver cancer, pancreatic cancer, etc.). The implanted gold label, like a positioning device, follows the movement of the tumor and can accurately guide the CyberKnife beam to focus on the tumor tissue, thereby minimizing damage to surrounding normal tissues. For superficial tumors, the gold label attached to the body surface is used as a substitute for the tumor itself, making it visible under KV tracking images, thereby achieving the purpose of tracking the tumor.

[0003] The gold label needs to achieve sub-millimeter (mm) position accuracy, because ordinary adhesive tape cannot achieve this function. In the current gold label implantation process, medical staff usually use image guidance and a thin puncture needle to deliver the gold label to the predetermined target position. However, due to various factors, such as gold label displacement, the distance between adjacent gold labels is too close (less than 2.0 cm), or the angle difference between the three gold labels is too small (less than 15 degrees), the implanted gold label may not meet the requirements of radiotherapy tracking. These factors not only increase the complexity of the operation, but may also lead to complications and cause strong pain to the patient. Utility Model Content

[0004] The utility model aims to provide a CyberKnife positioning gold label patch bag, which implants the gold label into the skin patch, innovates the idea of ​​gold label positioning, saves the needle puncture link, and alleviates the pain of patients.

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] Please also refer to Figure 1 to Figure 2 The CyberKnife positioning gold label patch bag of the utility model embodiment will be described in detail below in conjunction with the accompanying drawings. The bracket can be used in conjunction with the lifting structure.

[0022] like Figure 1 As shown, the CyberKnife positioning gold mark patch bag comprises a base layer 1, one side of the base layer 1 is bonded to the patient's skin, and the other side is bonded to a base 2, a fixing block 3 is fixed to the upper end of the base 2, and a covering layer 4 is covered on the base 2, one end of the covering layer 4 is fixedly connected to the base layer 1, and the other end is detachably installed to cover the base 2 and the fixing block 3, a groove 8 is provided inside the fixing block 3 away from the base 2, and a gold mark is placed inside the groove 8.

[0023] In this embodiment, the size of the fixing block is 1*1 cm.

[0024] The gold mark is placed inside the groove 8 , and an elastic film 9 is fixed at the bottom of the groove 8 . After the gold mark is placed, the gold mark is located between the elastic film 9 and the covering layer 4 .

[0025] As an implementation mode, a through groove 5 is provided on the covering layer 4, and the through groove 5 is symmetrically arranged about the middle part of the covering layer 4. The two through grooves 5 are respectively located on both sides of the fixing block 3. An adhesive rubber ring is provided on the covering layer 4, and the adhesive rubber ring is adhesively connected to the fixing block 3. The position of the adhesive rubber ring corresponds to the position outside the groove 8 on the fixing block 3.

[0026] A lifting block 6 is fixed to the end of the covering layer 4 away from the base layer 1 , and the lifting block 6 is integrated with the covering layer 4 .

[0027] During specific use, the base layer 1 adheres to the skin, and the groove 8 inside the fixing block 3 is used to place the gold label. Considering that the gold label will move autonomously if it is placed directly in the groove 8, and it is not easy to remove the gold label because it is fixed by gluing above the gold label, in this solution, the gold label is placed in the groove 8 provided with an elastic membrane 9.

[0028] After the gold mark is placed in the groove 8, the covering layer 4 is covered on the upper end of the fixed block 3. Since the through grooves 5 are arranged on the covering layer 4, the positions of the two through grooves 5 will be placed on both sides of the fixed block 3 as the covering layer 4 covers them. Then, at this time, the adhesive rubber ring of the covering layer 4 is completely placed on the fixed block 3 and bonded and fixed to the fixed block 3. Since the tension of the elastic film 9 will squeeze the gold mark, a covering layer 4 is covered on the top of the gold mark at this time to clamp the gold mark between the elastic film 9 and the covering layer 4, thereby preventing the gold mark from moving autonomously.

[0029] After the positioning is completed, when the gold label needs to be removed, the covering layer 4 is lifted and opened by the lifting block 6 to take out the gold label.

[0030] A through hole is further provided inside the covering layer, the through hole is located in the middle of the adhesive rubber ring, the length and width of the through hole are 2-2.5mm and 0.15-0.25mm respectively, and the gold mark can leak out through the through hole when placed in the groove.

[0031] Meanwhile, the elastic film 9 is made of polyurethane elastic film; the base layer 1, the covering layer 4, the base 2 and the fixing block 3 are all made of medical grade polylactic acid or polyvinyl alcohol materials, wherein the side of the base layer is sticky and hot melt adhesive can be used.

[0032] When used, the CyberKnife positioning gold label patch bag is used to fix the gold label, which specifically includes the following steps:

[0033] ① Patient preparation: put the patient in an appropriate position, clean and disinfect the skin in the treatment area;

[0034] ② Use optical body surface imaging equipment to scan the patient's body surface to obtain clear three-dimensional body surface images;

[0035] ③ Import the three-dimensional body surface image into the analysis software and use the three-dimensional surface calculation technology to determine the best affixation position of the gold label;

[0036] ④ Paste the gold label patch bag at the determined position;

[0037] ⑤ Place the gold label in the groove inside the gold label patch bag, cover the gold label with a covering layer, and let the gold label leak out along the through hole on the covering layer. Start tracking the gold label through the radiotherapy treatment equipment to perform treatment.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
