AI Technical Summary
During the breast puncture process, the breasts tend to relax when lying flat, which leads to puncture offset or misalignment, and the shaking of the hand when the doctor holds the puncture needle affects the accuracy of the puncture.
A breast surgical puncture positioning device is designed, including a cover, a transmission mechanism and an inner liner. The transmission mechanism drives the position and angle adjustment of the mounting seat and puncture cylinder through components such as hexagonal rotating head, worm and worm gear; the inner liner squeezes and shapes the breasts through airbags and pressure sensors to stabilize the breast shape.
It effectively avoids shaking and spreading of the breast during the puncture process, reduces the risk of puncture offset and dislocation, improves puncture accuracy, and reduces the impact of doctor's hand shaking on puncture accuracy.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of puncture positioning devices, in particular to a breast surgery puncture positioning device. Background Art
[0002] Breast lumps are a common manifestation of breast disease in women. A clear diagnosis must be made before treatment is taken. The most common method is to puncture the lump to obtain a specimen for pathological diagnosis. Breast puncture can be done by fine needle puncture or coarse needle puncture. Fine needle puncture uses an ordinary syringe to puncture and absorb the lesion cells. Its advantages are less trauma and less pain. However, it is only for cytological examination and cannot be used for the diagnosis of breast cancer. Coarse needle puncture uses a thick-caliber needle for puncture, which can perform histological examination and can be used as a diagnostic standard for breast cancer, but it is more traumatic, more painful, and more expensive.
[0003] However, many patients currently lie flat during breast puncture, which makes their breasts relatively loose and deformed in a flat manner. Breasts with a flat deformation are prone to puncture deviation or dislocation during the puncture operation. In addition, when the doctor holds the puncture needle for puncture, the shaking of the hand will also affect the accuracy of the puncture, and the puncture needle cannot be effectively limited and fixed to avoid shaking and tilting of the puncture needle.
[0004] Therefore, the utility model provides a breast surgical puncture positioning device to solve the above problems. Utility Model Content

[0012] Beneficial Effects
[0013] The utility model provides a breast surgical puncture positioning device. Compared with the prior art, it has the following beneficial effects:
[0014] When using the device, the doctor first controls the air intake and exhaust device through the control panel to inject air into the airbag, and the airbag expands. The expanded airbag squeezes and shapes the patient's breast to avoid shaking and flattening of the breast. Under the induction of the pressure sensor, when the squeezing pressure value reaches the specified value, the air intake and exhaust device stops working to prevent excessive squeezing pressure on the patient's breast, causing discomfort to the patient. Then the doctor drives the transmission mechanism to operate by rotating the hexagonal rotating head, thereby driving the mounting seat to move inside the slide groove to adjust the position of the puncture tube, and then rotates the puncture tube to adjust the angle of the puncture tube. Finally, the doctor performs breast puncture surgery through the puncture tube, thereby reducing the impact of the shaking of the doctor's hand on the puncture accuracy when holding the puncture needle for puncture.

[0024] When using the device, the doctor can drive the rotating rod 4 to rotate by rotating the hexagonal rotating head 5, thereby driving the worm 6 to rotate. Because the worm 6 is meshed and connected with the worm wheel 8 fixedly installed on the first rotating shaft 7, it synchronously drives the first rotating shaft 7 to rotate, and then drives the mounting seat 13 to slide in the provided slide groove 11 through the connecting plate 9 and the connecting rod 14, so that the position of the puncture tube 16 can be adjusted. Then, because both sides of the second rotating shaft 15 are transitionally matched with the mounting seat 13, the doctor can adjust the angle of the puncture tube 16 by rotating the second rotating shaft 15, and then the doctor can use the puncture tube 16 to perform breast puncture surgery, thereby reducing the influence of the shaking of the doctor's hand on the puncture accuracy when holding the puncture needle for puncture.
[0025] Embodiment 2:
[0026] See also Figure 1-5This embodiment provides a technical solution based on the first embodiment: an inner liner 18 is installed on the inner wall of the cover body 1, and the inner liner 18 includes an airbag 19, a pressure sensor 21 and a sponge layer 20. The sponge layer 20 is wrapped around the outside of the airbag 19, and a pressure sensor 21 is arranged between the airbag 19 and the sponge layer 20.

The expanded airbag 19 squeezes and shapes the patient's breast to avoid shaking and flattening of the breast. Then, under the induction of the pressure sensor 21, when the squeezing pressure value reaches a specified value, the air intake and exhaust device stops working to prevent excessive squeezing pressure on the patient's breast, causing discomfort to the patient.
