Abstract
Description
Technical Field
[0001] This utility model relates to a medical device, specifically an L-shaped breast retractor. Background Technology
[0002] With the development of the cosmetic surgery industry, breast augmentation surgery has also continued to evolve. There are three types of breast augmentation surgery: injection breast augmentation, implant breast augmentation, and autologous fat breast augmentation. Both implant breast augmentation and autologous fat breast augmentation require an incision to be made in a well-designed, concealed area of the breast with a scalpel. In subsequent surgeries, retractors are used to widen the incision and separate the skin and subcutaneous tissue to create a good surgical cavity.
[0003] Currently, for aesthetic reasons, incisions are generally made as small as possible. However, breast retractors have a simple structure, insufficient gripping force, and often fail to hold the breast, resulting in slippage. Moreover, the dissection effect is poor, which often requires the use of multiple instruments such as dissectors during surgery. Since the dissection range in the hidden area under the breast is limited, it is not possible to accommodate multiple instruments at the same time, thus affecting the good exposure of the surgical field. Utility Model Content
[0004] The purpose of this invention is to provide an L-shaped breast retractor. This invention has the advantages of good peeling effect, easy retraction, and convenient operation.
[0005] The technical solution of this utility model is: an L-shaped breast retractor, including a handle and a retractor body. The retractor body includes a first retractor part, a second retractor part and a third retractor part connected in sequence. The first retractor part is flat. The first retractor part and the second retractor part are connected at an angle θ less than 90°. The third retractor part is provided with a wavy hook head.
[0006] In the aforementioned L-shaped breast retractor, the hook head is provided with a sliding groove, and a hook head adjustment device is installed on the sliding groove. The hook head adjustment device includes a first unfolding hook head and a second unfolding hook head. The first unfolding hook head and the second unfolding hook head are respectively provided with a first sliding groove and a second sliding groove. Both the first sliding groove and the second sliding groove are provided with elastic buckles that can be slidably connected.
[0007] In the aforementioned L-shaped breast retractor, the length of the first retractor portion is shorter than that of the second retractor portion, which provides the retractor with better operating space and field of vision, and at the same time allows the force on the handle to be applied more effectively to the hook head.
[0008] In the aforementioned L-shaped breast retractor, a cold light source fiber optic conduit is provided on the outer side of the retractor body. The cold light source fiber optic conduit passes through the handle and connects to the fiber optic connector for easy operation.
[0009] In the aforementioned L-shaped breast retractor, the cold light source fiber optic conduit is also provided with a suction tube on the outside. The connector of the suction tube is set at an angle to the fiber optic connector, which facilitates blood and water suction while peeling, and can be rinsed when necessary.
[0010] Compared with the prior art, this utility model, by setting a wavy hook head, can better pull apart and peel off breast tissue, and is less prone to slipping; at the same time, a hook head adjustment device is provided on the hook head to further increase the effective area of the hook head, making the pulling force greater, easier to pull apart and easier to peel off.
[0011] Furthermore, a cold light source fiber optic conduit and a suction tube are installed on the retractor body to integrate the instruments, making it easier for doctors to operate and ensuring a better surgical field of vision. Attached Figure Description

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings, but it should not be construed as a basis for limiting this utility model.
[0017] Example. An L-shaped breast retractor, such as... Figures 1-3 As shown, it includes a handle 1 and a hook body 2. The hook body 2 includes a first hook part 21, a second hook part 22 and a third hook part 23 connected in sequence. The first hook part 21 is flat. The first hook part 21 and the second hook part 22 are connected at an angle θ, where 80°≤θ<90°. The length of the first hook part 21 is less than that of the second hook part 22.
[0018] The third hook part 23 is provided with a wavy hook head 3, the hook head 3 is provided with a sliding groove 30, and a hook head adjustment device 4 is installed on the sliding groove 30. The hook head adjustment device 4 includes a first unfolding hook head 41 and a second unfolding hook head 42. The first unfolding hook head 41 is provided with a first sliding groove 411, which is installed overlappingly with the sliding groove 30 and is slidably connected by two elastic buckles 43. The second unfolding hook head 42 is provided with a second sliding groove 421, which is installed overlappingly with the sliding groove 30 and is slidably connected by two elastic buckles 43.
[0019] The hook body 2 is provided with a cold light source fiber optic conduit 50 on its outer side, and the cold light source fiber optic conduit 50 passes through the handle 1 and connects to the fiber optic connector 51.
[0020] The cold light source fiber optic conduit 50 is also provided with a coaxial flushing tube 6 on its outer side. The flushing tube 6 is provided with a flushing connector 61 at one end near the fiber optic connector 51. The flushing connector 61 is set at an angle offset from the fiber optic connector 51. The flushing tube 6 is shorter than the cold light source fiber optic conduit 50.
[0021] During the surgery, an incision is first made in the pre-designed concealed area of the breast using a scalpel. The third retractor portion 23 of the retractor is used to widen the incision. Next, the elastic buckle 43 of the retractor is pressed tightly within the incision edge, and the hook head adjustment device 4 is opened. The locking elastic buckle 43 is then released, widening and enlarging the third retractor portion 23, allowing for retraction and dissection actions and providing good exposure of the surgical field. A cold light source fiber optic catheter is also installed to facilitate endoscopic operations. Blood or fluid can be promptly aspirated if present, or flushed with water through a suction tube and aspirated if the surgical field is blurred, making the procedure very convenient. After the surgery, the elastic buckle 43 of the retractor is pressed tightly within the incision edge, the hook head adjustment device 4 is closed, the retractor is removed, and the incision is sutured.
