Description

Technical Field

[0001] The utility model relates to the technical field of breast puncture, in particular to a positioning device for breast puncture. Background Art

[0002] Breast puncture is a common medical technology used to diagnose and treat breast-related diseases, such as breast lumps, breast cysts, etc. In order to perform breast puncture accurately, positioning devices are widely used to assist doctors in accurately positioning and guiding the puncture operation. The positioning device is usually composed of imaging technology, navigation system and injection components. Imaging technology mainly includes ultrasound imaging, magnetic resonance imaging and mammography. The injection component is another important component of the positioning device, which includes a puncture needle and a guide needle. The puncture needle is the actual tool for puncture. It is guided by the guide needle to position it at the puncture target. The injection component is usually designed to be reusable, which is convenient for doctors to perform multiple punctures.

[0046] In the utility model, the working steps of the device are as follows:

[0047] First, the placement bin 6 is rotated and taken out from under the cover plate 5, and then the medical gauze is placed in the placement bin 6, and then the placement bin 6 is fixed to the placement bin 6 by rotating it clockwise;

[0048] During the operation, the puncture needle 12 is engaged with the top of the connecting column 3 through the fixed structure 2, so that the puncture needle 12 passes through the device housing 1 and extends into the guide needle 7. The guide needle 7 is first inserted into the position where puncture is required in the patient's body, and then the connecting column 3 in the device housing 1 is pressed downward, so that the moving block 8 drives the puncture needle 12 to move downward, and the moving block 8 is downwardly sleeved on the outer surface of the circular rod 10. The sliders 9 on both sides of the moving block 8 slide downward in the slide groove, and then the moving block 8 moves downward and the reset spring 11 is forced to retract. At this time, the puncture needle 12 passes through the guide needle 7 and enters the patient's body for sampling. After the sampling is completed, the pressing of the connecting column 3 is stopped, and the reset spring 11 rebounds, so that the moving block 8 and the connecting column 3 drive the puncture needle 12 to move upward, and finally the fixed structure 2 drives the puncture needle 12 to be taken out;

[0049] When the guide needle 7 penetrates into the patient's body, the device shell 1 moves downward, causing the multiple groups of springs 4 to retract under force, driving the cover plate 5 and the placement chamber 6 to move upward. At this time, the placement chamber 6 and the medical gauze are located on the surface of the patient. For the absorption of blood on the patient's surface, after the operation, the placement chamber 6 can be taken out counterclockwise to take out the used mobile gauze, and the cover plate 5 and the placement chamber 6 can be disinfected and reused.
