Description

Technical Field

[0001] The invention relates to the technical field of medical ultrasound, in particular to a breast puncture device under ultrasound guidance. Background Art

[0002] Breast lumps are common signs of breast disease. Women's breasts are inherently uneven, and the lumps that many women find themselves are just normal breast protrusions. Before menstruation, these lumps will become more obvious and easier to touch. Most of the breast lumps found clinically are benign lesions, such as breast adenosis, breast fibroadenoma, breast cysts, intraductal papilloma, breast duct ectasia, and breast tuberculosis. Breast adenosis is also known as breast hyperplasia. In terms of the characteristics of the lumps, breast adenosis often finds multiple nodules of varying sizes and unclear boundaries on both breasts at the same time or successively, which can be pushed. Breast fibroadenoma is mostly single, with clear boundaries, neat edges, smooth surface, and can be moved. Breast puncture needle biopsy is to use a thick or thin puncture needle to pierce the breast lump to obtain biopsy tissue or cell examination. Ultrasound-guided puncture therapy is a medical method that uses ultrasound technology.

[0003] During breast puncture, the patient's breast needs to be fixed first, but the size of each person's breast is different. Currently, an ultrasound-guided breast puncture device on the market does not have a good fixation effect on breasts of different sizes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention pushes the equipment box in front of the bed, drives the rotating long axis to rotate with a driving motor, and converts the rotating mounting plate from a vertical state to a horizontal state, so that the rotating mounting plate is laid horizontally when in use and is placed vertically for storage when not in use, thereby avoiding the device from occupying a large space when not in use and facilitating movement.

[0016] 2. In the present invention, the function of the lateral displacement structure is to drive the puncture positioning component to move horizontally, specifically as follows: the driving motor three drives the lateral threaded rod to rotate, and under the threaded transmission action of the lateral threaded rod and the push-pull strip connecting plate, the push-pull strip connecting plate drives the push-pull strip to move vertically, so that the rotating mounting plate can move left and right, mainly to drive the positioning body to move, so that the positioning body can be changed between the left breast and the right breast, so that the device can position and adsorb any breast on a single side, and the servo drives a vertical axis to rotate, and under the transmission action of the belt transmission member one, the two vertical axes can rotate. At this time, under the rotation action of the belt transmission member one, the positioning device is fine-tuned horizontally at the top of the rotating mounting plate, so that the positioning body has a two-stage moving structure when it moves horizontally, that is, the overall space occupied by the device is reduced when it is unfolded and it will not be too large, avoiding the influence of volume problems on related operations, and the flexibility is greater.

[0017] 3. In the present invention, the extension of the electric telescopic rod drives the lateral displacement structure to move upward, so that the height of the positioning body can be adjusted. The distance between the positioning body and the breast can be adjusted according to the different fatness and size of the patient and the size of the breast. It is not only suitable for different patients, but also ensures the effect of breast positioning. The second driving motor drives a gear shaft to rotate. Under the transmission action of the second belt transmission member, the two gear shafts rotate simultaneously. The sliding bottom plate is driven by the transmission belt connecting block to move forward and backward, and the position of the positioning body is adjusted forward and backward. It is more accurate than achieving the front and rear position adjustment of the positioning body by pushing the equipment box.

[0018] 4. The present invention completely covers the areola by the suction cup, and then the vacuum pump generates negative pressure to evacuate air. The suction force is transmitted to the inside of the hollow vertical tube through the connecting tube and the suction tube in turn. The negative pressure inside the hollow vertical tube and the suction cup makes the areola of the breast completely fit with the inner wall of the suction cup, so that the breast can be adsorbed and positioned from the areola. The shielding range of the breast is small, which is more conducive to the doctor's puncture operation. Then, the rotating knob can drive the vertical threaded rod to rotate. Under the vertical transmission action of the vertical threaded rod and the welding plate, the spacing between the movable mounting block and the welding plate is adjusted, that is, the breast is stretched up and down as a whole to avoid sagging of the breast affecting the positioning, and the threaded control can be stopped at any time, with strong controllability and more flexibility.

[0019] 5. In the present invention, the cover plate is threadedly connected to the hollow externally threaded barrel through a threaded hole opened on the top thereof, that is, the hollow externally threaded barrel can be rotated by the convex rod, and the probe can be driven to move downward, so that the probe part of the probe is completely fitted with the breast, thereby ensuring the effect of ultrasonic detection. At the same time, the probe is fixed by fixing bolts between the fixing connecting plate and the circular ring block, and the threaded installation is convenient for subsequent disassembly and replacement, and maintenance is more convenient.

[0039] The working principle of the present invention is:

[0040] When in use, the equipment box 1 is pushed in front of the bed, and the driving motor 4 drives the rotating long axis 7 to rotate, so that the rotating mounting plate 8 is converted from a vertical state to a horizontal state, so that the rotating mounting plate 8 is horizontally placed when in use and vertically placed when not in use, so as to avoid the device occupying a large space when not in use and facilitate movement;

[0041] The function of the lateral displacement structure 33 is to drive the puncture positioning assembly 3 to move horizontally. Specifically, the driving motor 3 51 drives the lateral threaded rod 47 to rotate. Under the threaded transmission action of the lateral threaded rod 47 and the push-pull strip connecting plate 49, the push-pull strip connecting plate 49 drives the push-pull strip 48 to move vertically, so that the rotating mounting plate 8 can move left and right, mainly to drive the positioning body 18 to move, so that the positioning body 18 can be changed between the left breast and the right breast, so that the device can position and adsorb any breast on a single side, and the servo drives a vertical axis 11 to rotate. Under the transmission action of the belt transmission member 10, the two vertical axes 11 can rotate. At this time, under the rotation action of the belt transmission member 10, the positioning device 12 is fine-tuned on the top of the rotating mounting plate 8 for horizontal movement, so that the positioning body 18 has a two-stage moving structure when it moves horizontally, that is, the overall occupied space of the device is reduced when it is unfolded, and the related operations are not affected by the volume problem, and the flexibility is greater;

[0042] The extension of the electric telescopic rod 40 drives the lateral displacement structure 33 to move upward, so that the height of the positioning body 18 can be adjusted. The distance between the positioning body 18 and the breast can be adjusted according to the different fatness and size of the patient and the size of the breast. It is not only suitable for different patients, but also ensures the effect of breast positioning. The driving motor 45 drives a gear shaft 44 to rotate. Under the transmission action of the belt transmission member 43, the two gear shafts 44 rotate at the same time. The sliding bottom plate 39 is driven by the transmission belt connecting block 42 to move forward and backward. The position of the positioning body 18 is adjusted forward and backward, which is more accurate than the front and rear position adjustment of the positioning body 18 by pushing the equipment box 1.

[0043] The suction cup 22 completely covers the areola, and then the vacuum pump 15 generates negative pressure to evacuate air. The suction force is transmitted to the inside of the hollow vertical cylinder 23 through the connecting tube 16 and the suction tube 17 in turn. The negative pressure inside the hollow vertical cylinder 23 and the suction cup 22 makes the areola of the breast completely fit with the inner wall of the suction cup 22, so that the breast can be adsorbed and positioned from the areola. The covering range of the breast is small, which is more conducive to the doctor's puncture operation. Then, the rotating knob 21 can drive the vertical threaded rod 20 to rotate. Under the vertical transmission action of the vertical threaded rod 20 and the welding plate 14, the spacing between the movable mounting block 13 and the welding plate 14 is adjusted, that is, the breast is stretched up and down as a whole to avoid sagging of the breast affecting the positioning, and the threaded control can be stopped at any time, with strong controllability and more flexibility.

[0044] The cover plate 24 is threadedly connected to the hollow externally threaded tube 25 through a threaded hole opened on its top, that is, the hollow externally threaded tube 25 can be rotated by the protruding rod 26, and the probe 27 can be driven to move downward, so that the probe part of the probe 27 is completely in contact with the breast, thereby ensuring the effect of ultrasonic detection. At the same time, the probe 27 is fixed by a fixing bolt 29 between the fixing connecting plate 28 and the circular ring block 32, and the threaded installation is convenient for subsequent disassembly and replacement, and maintenance is more convenient.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
