AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The embodiment of the invention discloses a mammary gland flap dissociation device. The mammary gland flap dissociation device comprises a fixing rod, a handle, a first positioning adjusting mechanism, a pressing piece, a second positioning adjusting mechanism and a scalpel blade. Wherein the handle is connected to the fixing rod. The first positioning adjusting mechanism is arranged on the fixing rod. And the pressing sheet is arranged on the first positioning adjusting mechanism. And a positioning structure is arranged on the pressing sheet. And the second positioning adjusting mechanism is arranged on the fixing rod. And the scalpel blade is mounted on the second positioning and adjusting mechanism. In addition, the scalpel blade is located below the same side of the pressing piece. According to the mammary gland flap dissociation device, the thickness of the dissociated flap can be determined according to the actual situation, heat damage is avoided, the length of the scalpel can be adjusted, and the range of the flap needing to be dissociated can be reached.
