Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a breast nodule positioning auxiliary device. Background Art

[0002] In recent years, the incidence of breast cancer has been increasing. The most common clinical manifestation of breast cancer is breast lumps, also known as breast nodules. Usually, after the breast lumps are found, they need to be surgically removed and biopsied. At present, the removal of breast lumps mainly uses the Mammotome device for minimally invasive removal. When the Mammotome device is used for breast lumps removal, it is generally performed under ultrasound guidance. During the operation, the breast lump is first located using the "T-shaped positioning method" using ultrasound equipment, and then marked on the patient's body surface. Then, under ultrasound guidance, the breast lump is removed through the Mammotome device. The removed breast lump will be biopsied after the operation to check whether the breast lump is malignant. If it is malignant, further treatment is required. The marks on the patient's body surface after the operation will disappear over time and due to the patient's bathing and other behaviors. At the same time, since the hospital does not have clear marking data on the location of the breast lump, it is difficult for patients to determine whether it is a surgical residue or a new lump if they find a breast lump after the operation, which is easy to cause medical disputes.

[0003] Chinese patent CN209032673U discloses a breast lump locator, which has the following beneficial effects: the device has a novel structure, ingenious design, and is easy to use, and is convenient for accurately determining the actual location of the patient's body part, thereby facilitating further treatment. Five detailed embodiments are given, and if a patient finds a breast lump after surgery, it can be easily determined whether it is a surgical residue or a new lump, thereby reducing the possibility of causing medical disputes.

[0004] However, based on clinical use and hospital feedback, we know that the device mainly locates tumor nodules through a protractor, a reinforcement beam, a support mechanism, a turntable, an operating port, a ruler and an auxiliary measuring machine. However, due to the circular structure of the protractor and turntable, there is a lack of a clear "base point" as the positioning reference of the device in the secondary review and positioning. Although the positioning of tumor nodules can be roughly confirmed during use, because the nodules regenerated in the early stage or after surgery are very small, this can still easily lead to misjudgment of new and old tumors and positioning deviations. The effectiveness and practicality of use need to be further improved. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] Therefore, the purpose of the utility model is to provide a breast nodule positioning auxiliary device to solve the problem that the breast nodule locator in the prior art proposed in the above-mentioned background technology lacks a clear "base point" as the positioning reference of the device in the secondary review and positioning. Although the positioning of the lump nodule can be roughly confirmed during use, because the nodules regenerated in the early stage or after surgery are very small, it is still easy to cause misjudgment of new and old lumps and positioning deviation.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a breast nodule positioning auxiliary device, which includes a positioning base ring, a bottom circle of the positioning base ring is provided with a plurality of support components that can be positioned on the body, an annular protractor is slidably installed along a radial circle on the upper end of the positioning base ring, a radial circle on the inner side of the annular protractor has a slide groove 1, the inner side of the annular protractor has a scale along its diameter direction and the two ends slide on the inner side of the slide groove 1 through sliders, a first positioning sleeve is fixed to the middle part of the scale and is coaxial with the annular protractor, a positioning ruler is horizontally fixedly connected to one side of the outer wall of the annular protractor, a slide groove 2 is provided on one side of the positioning ruler along its length direction, and a second positioning sleeve is provided on one side of the positioning ruler and slides on the inner side of the slide groove 2 through a slider.

[0008] As a preferred solution of the breast nodule positioning auxiliary device described in the utility model, a supporting component is also provided at the bottom of the outer end of the positioning ruler.

[0009] As a preferred solution of a breast nodule positioning auxiliary device described in the utility model, the support assembly includes a support leg fixed to the bottom of the positioning base ring or the bottom of the positioning ruler, a universal damping shaft arranged at the bottom of the support leg, and a suction cup located at the bottom of the universal damping shaft.

[0010] As a preferred solution of the breast nodule positioning auxiliary device described in the utility model, an upper portion of one end of the scale also has an arrow mark pointing to the annular protractor.

[0011] As a preferred solution of the breast nodule positioning auxiliary device described in the utility model, a connecting seat that can be snapped and plugged with the positioning ruler is fixed on one side of the outer wall of the annular protractor.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when using the breast nodule positioning auxiliary device, the positioning base ring and the annular protractor are positioned above the patient's breast through multiple support components, so that the first positioning sleeve is centered with or in contact with the patient's nipple, and then the annular protractor and the positioning ruler are rotated, and the relative position of the second positioning sleeve is slid and adjusted until the second positioning sleeve is centered in contact with the other nipple, and then the positioning ruler is stabilized by the support component. In this way, the initial position and angle of the annular protractor can be determined after positioning the two points in a straight line, and then the scale is rotated and reaches the patient's part, and the actual position of the patient's nodule is determined by the fine readings on the scale, so as to facilitate further treatment; if a nodule or mass is found in the patient after surgery, the rotation angle and specific position of the annular protractor are determined by the specific positioning of the two points in a straight line, thereby greatly reducing the possibility of secondary positioning deviation and misjudgment, and then it is easy to judge whether it is a surgical residue or a new mass, reducing the possibility of causing medical disputes, and the use and operation are more convenient and reasonable.
