Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a flap separation device for non-inflatable endoscopic breast surgery. Background Art

[0002] Endoscopic breast surgery is an important development direction in modern breast surgery. The incision is usually designed in hidden parts such as the armpit. Through endoscopic instruments, a cavity is gradually established to reach the lesion site, and finally surgical operations such as tumor or gland resection are completed. The breast is composed of skin, adipose connective tissue, and glands from shallow to deep. The skin flap is a structure that needs to be preserved during the operation and is composed of skin and part of the adipose connective tissue; since the breast is a solid organ without natural cavities, establishing a cavity and an operating space during the operation is the key to the success of the surgery. Separating the skin flap is the key point and difficulty in establishing a cavity in endoscopic breast surgery, and it is also one of the important steps in breast surgery to remove the lesion; according to the different methods of establishing a cavity in endoscopic breast surgery, it can be divided into the inflation method and the non-inflation method. The inflation method injects carbon dioxide at an appropriate pressure to maintain the operating space and provide partial tension to the separation surface; the non-inflation method mainly places a retractor to support the operating space and generate tension.

[0003] Currently, in endoscopic breast surgery, there are high requirements for the thickness and uniformity of the skin flap. During endoscopic breast surgery, it can only be judged through the picture inside the incision on the display screen. The separation surface of the skin flap is in the adipose connective tissue, without a clear dividing line, and there is a lack of distance reference between the inside and outside of the skin flap, which largely depends on the experience of the surgeon; in addition, the retractor cannot provide a backward pulling force for the skin flap, and the skin flap is prone to forward sliding during operation, resulting in displacement of the separation surface; if the skin flap is too thin, complications such as skin burns, ischemic necrosis, and secondary infections are likely to occur, and if the skin flap is too thick, there are risks such as tumor residue and recurrence, making it difficult to separate the skin flap; continuously pulling the skin flap during the operation is laborious, and the separated tissue inside the incision is likely to block the field of view. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides the following technical solutions: A flap separation device for non-inflatable endoscopic breast surgery, comprising a support assembly and a separation assembly.

The pull screw rod is threadedly connected through the thread grooves provided on the semi-circular grooves. A clamping plate is slidably arranged on one slider, and a clamping groove is provided on the other slider.
