Embodiment 1
[0036] Such as Figure 1-6 As shown, a device for minimally invasive resection of breast nodules includes an outer sleeve 2 and an inner sleeve sleeved inside it. An annular space is formed between the outer sleeve 2 and the inner sleeve, and the contraction in the annular space An expansion device is provided, and the expansion device can move along the axial direction of the outer sleeve and extend out of the outer sleeve. The expansion device includes a plurality of elastic ribs arranged inside the outer sleeve, and the circumference of the plurality of elastic ribs is evenly distributed, and each elastic rib Arranged along the axial direction of the outer casing, multiple umbrella ribs are connected through the diaphragm 4 and form a ring-shaped closed structure. When the end of the expansion device moves to the outside of the outer casing, the end of the expansion device expands and forms a trumpet-shaped structure for The lumen adjacent to the breast nodule is dilated. ...
Embodiment 2
[0046] The difference between this embodiment and embodiment 1 is that the inner casing is canceled, and the connection mode of the ribs is changed at the same time. The working principle is the same, as follows:
[0047] Such as Figure 7 As shown, a device for minimally invasive resection of breast nodules includes an outer sleeve with an open upper end, and a plurality of elastic ribs arranged inside, and the lower ends and middle parts of the plurality of elastic ribs are provided with fixing rings 12 , two fixing rings are sleeved in the outer casing, the fixing ring 12 at the lower end positions the positions of multiple elastic ribs, and the fixing ring is connected to the control slider 1 at the same time, and the upper fixing ring is located at the upper end of the guide section of the elastic ribs , the upper fixing ring is used to apply deformation force to the deformation section of the elastic rib, and the other end of the outer casing is provided with a plurality...
