Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a fixing device used in minimally invasive excision of breast lumps. Background Art

[0002] Minimally invasive excision of breast lumps is a minimally invasive surgery used to treat breast lumps. This surgery uses ultrasound imaging to accurately locate the lump, and then uses a special instrument to remove the lump to ensure the accuracy and completeness of the removal. During the operation, the ultrasound is used to locate the location of the lump while using a minimally invasive excision knife to remove the lump. In order to better remove the lump in the breast, the position of the breast needs to be fixed for subsequent operations.

[0003] In this operation, due to the different shapes of breasts of each patient, for example, some patients have sagging or obvious outward expansion of breasts, and the mass happens to be located in the lower or outer quadrant. When a single person performs minimally invasive excision surgery, it is relatively difficult to locate the position of the mass and the operation is inconvenient. Generally, another person is needed to help fix the breast to facilitate the operation. Considering the limited medical resources of the hospital, coordinating two surgeons to perform the operation will be more time-consuming overall, and there may also be coordination problems that make the operation inconvenient. Summary of the invention

[0004] The present invention provides a fixation device for minimally invasive excision of breast lumps, which can facilitate single-person surgery and fix breasts of different shapes, making the entire surgical process simpler and reducing the complexity of coordination and communication during double-person surgery.
