AI Technical Summary
In current breast cancer surgeries, high-frequency electrosurgical units and ordinary scalpels are unable to effectively preserve the uniformity of skin flap thickness, leading to thermal damage or destruction of the vascular network. Furthermore, the scalpel length under laparoscopy is insufficient, making it difficult to achieve distant flap mobilization.
A breast flap freeing device was designed, including a fixing rod, a handle, a positioning and adjustment mechanism, and an adjustable-length scalpel. By adjusting the position of the pressure plate and the scalpel blade, the uniformity of the flap thickness is ensured and thermal damage is avoided, adapting to different surgical needs.
It allows for adjustment of flap thickness based on actual conditions to avoid thermal damage, and the scalpel can be adjusted in length to meet the needs of flap dissection in different ranges.

[0026] This invention discloses a breast flap freeing device.
[0027] like Figure 1 , Figure 2 As shown, the breast flap freeing device includes a fixing rod 100, a handle 200, a first positioning adjustment mechanism 300, a pressure plate 400, a second positioning adjustment mechanism 500, and a scalpel blade 600.
[0028] The handle 200 is connected to the fixed rod 100.
[0029] The first positioning adjustment mechanism 300 is mounted on the fixed rod 100.
[0030] For example, such as Figure 1 , Figure 2As shown, the first positioning and adjusting mechanism 300 includes an upper and lower movable sleeve 310, a telescopic frame 320, and an extension fixing plate 330. One end of the telescopic frame 320 is connected to the upper and lower movable sleeve 310. The other end of the telescopic frame 320 is connected to the extension fixing plate 330. The upper and lower movable sleeve 310 is movably fitted onto the fixed rod 100. The upper and lower movable sleeve 310 is fixed to the fixed rod 100 by a first threaded locking member 340.
[0031] Specifically, the fixed rod 100 has a second strip-shaped mounting hole 110 and a third strip-shaped mounting hole 120 that are perpendicular to each other. The upper and lower movable sleeves 310 have a first through hole 311 and a first threaded hole 312 that are perpendicular to each other. In the connected state, the telescopic frame 320 passes through the second strip-shaped mounting hole 110 and the first through hole 311 and is connected to the upper and lower movable sleeves 310. The first threaded locking member 340 passes through the first threaded hole 312 and is inserted into the third strip-shaped mounting hole 120 to lock the telescopic frame 320 and the upper and lower movable sleeves 310 onto the fixed rod 100. As a preferred embodiment, the first threaded locking member 340 can lock a bolt, such as a wing bolt, to facilitate tightening and loosening operations.
[0032] Furthermore, in the connected state, the telescopic frame 320 passes through the second strip-shaped mounting hole 110 and the first through hole 311, and is horizontally movable to the upper and lower movable sleeves 310 to provide additional telescopic length.
[0033] The tablet press 400 is located in the first positioning adjustment mechanism 300. Furthermore, a positioning structure 410 is provided on the tablet press 400.
[0034] Specifically, a first strip-shaped mounting hole 331 is provided on the extension fixing plate 330. A threaded connecting post is provided on one side of the pressure plate 400. In the connected state, the threaded connecting post passes through the first strip-shaped mounting hole 331 and connects to the locking nut 420. As a preferred embodiment, the locking nut 420 can be a wing nut for easy tightening and loosening. A countersunk hole 332 is provided on the extension fixing plate 330. A connecting hole is provided on the telescopic frame 320. A countersunk screw or countersunk bolt passes through the countersunk hole 332 and connects to the connecting hole to fix the extension fixing plate 330 to the telescopic frame 320. By adopting the above connection method, the space between the pressure plate 400 and the scalpel is unobstructed.
[0035] For example, the positioning structure 410 can be an arc-shaped structure formed on the compression tablet 400. On the one hand, the positioning structure 410 can play a certain positioning role; on the other hand, by setting the positioning structure 410, the nipple can pass through during freeing, thereby preventing uneven skin flap thickness caused by the nipple blocking during freeing.
[0036] The second positioning adjusting mechanism 500 is arranged on the fixed rod 100.
[0037] The second positioning adjusting mechanism 500 includes a surgical knife handle 510 and a second through hole 130 arranged on the fixed rod 100. One end of the surgical knife handle 510 is movably threaded in the second through hole 130. The other end of the surgical knife handle 510 is connected with the surgical knife blade 600. A second threaded hole 140 perpendicular to the second through hole 130 is arranged on the fixed rod 100. A second threaded locking piece 520 is threaded through the second threaded hole 140 to lock the surgical knife handle 510 on the fixed rod 100. The second threaded locking piece 520 can be a locking bolt, such as a butterfly bolt, to facilitate tightening and loosening operations.
[0038] The surgical knife blade 600 is mounted on the second positioning adjusting mechanism 500. The surgical knife blade 600 is located on the same side below the pressing piece 400.
[0039] The use process of the breast flap releasing device is as follows:
[0040] The positioning structure 410 on the pressing piece 400 is positioned at the nipple position. The horizontal position is adjusted by the threaded connecting column arranged on the pressing piece 400 at the position of the first bar-shaped mounting hole 331. The up-down position of the telescopic frame body 320 and the extension fixed piece 330 is adjusted by the up-down movable sleeve 310 in the first positioning adjusting mechanism 300, so as to adjust the up-down position of the pressing piece 400. The distance between the pressing piece 400 and the surgical knife blade 600 is adjusted, so as to adjust the thickness of the flap releasing.
[0041] The left-right position of the surgical knife handle 510 in the second positioning adjusting mechanism 500 is adjusted, so as to adjust the left-right position of the surgical knife blade 600, thereby adjusting the size of the flap releasing.
[0042] In summary, the breast flap releasing device can determine the thickness of the released flap according to the actual situation, without thermal damage, and the surgical knife can be adjusted in length, so as to reach the range of the flap to be released.
[0043] It should be noted that all the features disclosed in the specification, or all the steps of the disclosed methods or processes, can be combined in any manner, except for mutually exclusive features and / or steps.
[0044] In addition, the above specific embodiments are exemplary, and those skilled in the art can think of various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed range of the present application and fall within the protection scope of the present application.
