Yur-Ren Kuo, Chief of Surgery at the Kaohsiung Medical University Chung-Ho Memorial Hospital (KUMH), is concerned about oral cancer patients' chronic low self-esteem due to the fleshy masses left around their mouths after surgery, and even the symptoms of incessant salivation. The Tissue Resection Power-assist System has thus been developed in collaboration with the Metal Industries Research and Development Centre to improve the appearance of patients with incomplete mouth closure.

As an internationally renowned reconstructive plastic surgeon specialising in reconstructive head and neck cancer surgery, Dr. Kuo has often seen oral cancer patients reluctant to remove their masks because of the aesthetic impact of the fleshy masses around their mouths, so he decided to solve this problem. After years of research, Kuo tried to change the shape of the lips by developing an innovative ladder flap to allow patients to close their mouths.

When he saw an orthopaedic surgeon performing arthroscopic surgery with a rotary knife in the operating room, he was inspired to apply the rotary knife to flap liposuction, using this system in combination with new surgical techniques to successfully treat patients.

Dr. Kuo collaborated with the Metal Industries Research and Development Centre, one of Taiwan's strongest medical material centres, to develop and design a new step flap combined with a minimally invasive planer system for the reconstruction of lip and cheek deformities and incomplete mouth closure.

The product is named "KP kits" and can be used for arthroscopic surgery, removal of hypertrophic skin flaps, and even liposuction and body sculpting. Recently, Dr. Kuo and the Centre have applied for patents in many countries, and have already contracted with manufacturers to authorize production.
