Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a nodule positioning device. Background Technology

[0002] Breast nodules are commonly seen in breast hyperplasia and breast neoplasia, including benign breast tumors (such as fibroadenomas and phyllodes tumors) and malignant breast tumors (breast cancer). A significant number of nodules fall between benign and malignant, requiring minimally invasive excision or biopsy of the breast mass under ultrasound guidance using a specialized rotary excision device, known as Mammotome breast surgery.

[0003] For example, Chinese utility model patent (CN211962224U) discloses a device for facilitating the location of breast nodules. It states: "The advantage of this utility model is that the device for facilitating the location of breast nodules, namely the adhesive film, can be directly applied to the patient's breast for routine X-ray fluoroscopy and MRI / CT scans. Because the hollow tube containing contrast agent in the contrast layer can visualize the nodules, it facilitates their location." It also states: "Currently, imaging examinations relying solely on quadrants and clock positions are not accurate enough. The breast lacks clearly defined anatomical structures for distinguishing locations. Without an ultrasound surgeon present during surgery, the breast surgeon needs to accompany the patient, manually locate the nodules, make a mark on the breast with a pen, and then draw a marker, which is inconvenient and inhumane."

[0004] In summary, existing technologies utilize a film applied to the patient's breast, followed by conventional X-ray fluoroscopy and MRI / CT scans to locate breast nodules. However, this method has the following technical problems: When applying the film, the position can only be adjusted by changing the relative position of the nipple and the opening. The nipple position may change due to different patient positions, affecting the accuracy of subsequent re-examinations and consequently the accuracy of identifying and locating new and old lumps. Therefore, this application proposes a nodule location device to solve the technical problems mentioned in the aforementioned patents, providing a new technical solution. Utility Model Content

[0005] Based on this, it is necessary to provide a nodule positioning device to address the aforementioned technical problems. By attaching the auxiliary mechanism to the patient's suprasternal notch and xiphoid process, it provides a longitudinal reference for subsequent adjustment of the patient's nipple position. By adjusting the patient's body position, the relative position of the patient's nipple is made closer during the first positioning and the second follow-up examination, thereby improving the consistency of the positioning patch being attached to the patient's breast during the first positioning and the second follow-up examination, and thus improving the accuracy of judging and locating new and old lumps.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As described in the background art, when the above-mentioned device is applied, the position of the film can only be adjusted by adjusting the relative position of the nipple and the through hole. However, the position of the nipple may change due to different patient positions, which will affect the accuracy of subsequent re-examination and thus affect the accuracy of the judgment and location of new and old masses.

[0029] To solve this technical problem, this utility model provides a nodule positioning device, which is applied to the positioning of breast nodules in non-obese patients.

[0030] For details, please refer to Figures 1-2 The nodule positioning device specifically includes:

[0031] Positioning sticker 1 and auxiliary mechanism 2, with a guiding mechanism 3 provided on the auxiliary mechanism 2;

[0032] The auxiliary mechanism 2 includes a connecting strip 4, a lower adhesive layer 5, and a first positioning component. The bottom of the connecting strip 4 is fixedly connected to the lower adhesive layer 5.

[0033] In this application, the positioning patch 1 has the same specific structure and working principle as the existing device for facilitating the positioning of breast nodules mentioned in the background art.

[0034] The nodule positioning device provided by this utility model provides a longitudinal reference for subsequent adjustment of the patient's nipple position by attaching the auxiliary mechanism 2 to the patient's suprasternal notch and xiphoid process. By adjusting the patient's body position, the relative position of the patient's nipple is made closer during the first positioning and the second follow-up examination, thereby improving the consistency of the positioning patch 1 being attached to the patient's breast during the first positioning and the second follow-up examination, and thus improving the accuracy of the judgment and positioning of new and old lumps.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figures 2-5 A nodule positioning device, comprising:

[0038] Positioning sticker 1 and auxiliary mechanism 2, with a guiding mechanism 3 provided on the auxiliary mechanism 2;

[0039] The auxiliary mechanism 2 includes a connecting strip 4, a lower adhesive layer 5, and a first positioning component. The lower adhesive layer 5 is fixedly connected to the bottom of the connecting strip 4. The auxiliary mechanism 2 provides support for adjusting the longitudinal position of the patient's nipple during the second follow-up examination. The connecting strip 4 should be long enough to accommodate patients of different body types and ensure that the distance between the suprasternal notch and the xiphoid process is less than the length of the connecting strip 4 for most body types.

[0040] The first positioning component includes a scale layer 6. The scale layer 6 is fixedly connected to the top of the lower adhesive layer 5, and the upper adhesive layer 7 is fixedly connected to the top of the scale layer 6. It is worth mentioning that when the auxiliary mechanism 2 is not in use, protective films should be pasted on the sides of the lower adhesive layer 5 and the upper adhesive layer 7 that are far apart from each other to prevent dust and other impurities from adhering to the lower adhesive layer 5 and the upper adhesive layer 7, which would reduce their adhesive ability. In addition, the lower adhesive layer 5 and the upper adhesive layer 7 are both made of transparent material, and the connecting strip 4 and the scale layer 6 are made of soft material to ensure that they can better conform to the patient's body curves when applied to the patient.

[0041] The guiding mechanism 3 includes a movable shell 8, a rubber pad 9, a second positioning component, and a third positioning component. The movable shell 8 is movably attached to the top of the upper adhesive layer 7. The inner wall of the movable shell 8 is fixedly connected to the rubber pad 9. The rubber pad 9 can provide friction for the position of the movable column 10, so that the lifted movable column 10 can be kept in the current position under the action of friction between the movable column 10 and the rubber pad 9, and can also prevent the movable column 10 from easily rotating relative to the rubber pad 9.

[0042] The second positioning component includes a movable column 10, which is slidably connected to the inner wall of the rubber pad 9. The outer wall of the movable column 10 is provided with a first scale 11, which provides a reference for the height of the patient's nipple during the second re-examination.

[0043] The third positioning component includes an I-shaped plate 12. The top of the movable column 10 is fixedly connected to the I-shaped plate 12. The outer wall of the I-shaped plate 12 is fixedly connected to a soft band 13. The outer wall of the soft band 13 is provided with a second scale 14, which provides a reference for the transverse position of the patient's nipple during the second re-examination.

[0044] Both the lower adhesive layer 5 and the upper adhesive layer 7 are made of acrylic adhesive.

[0045] With the above structural design, during the initial positioning of the device, the auxiliary mechanism 2 is removed. Medical personnel determine the patient's suprasternal notch and xiphoid process by observation or touch. Then, the protective film on the lower adhesive layer 5 is peeled off, and the initial scale on the scale layer 6 is aligned with the patient's suprasternal notch. The lower adhesive layer 5 is then adhered to the patient's skin, ensuring the patient's xiphoid process is below the lower adhesive layer 5. Next, the protective film on the upper adhesive layer 7 is peeled off, and the movable shell 8 is adhered to the upper adhesive layer 7 according to the position of the patient's nipple. The position of the movable shell 8 corresponding to the scale layer 6 is recorded. Then, the movable column 10 is pulled upwards to the appropriate position according to the nipple height. Based on the lateral position from the nipple, the soft band 13 is unfolded at an appropriate distance. During this process, the movable column 10 can be rotated in the horizontal plane so that the bottom edge of the soft band 13 is aligned with the patient's nipple. The nipple is brought into contact with the breast, and the corresponding scales on the first scale 11 and the second scale 14 are recorded. Then, the positioning sticker 1 is attached to the patient's breast with the nipple as the reference point. The auxiliary mechanism 2 and the guiding mechanism 3 can then be removed to perform the positioning test. When the patient is examined a second time, the new auxiliary mechanism 2 is attached to the same position on the patient's body. According to the position of the movable shell 8 relative to the scale layer 6 during the first positioning, the movable shell 8 is attached to the upper adhesive layer 7. Then, according to the recorded scales of the first scale 11 and the second scale 14, the positions of the movable column 10 and the soft band 13 are adjusted. The patient's body position is then adjusted so that the patient's nipple is as close as possible to the position relative to the patient's sternum during the first positioning. Then, the positioning sticker 1 is attached to the patient's breast again with the nipple as the reference point.
