In recent years, laparoscopic surgery has become increasingly popular due to its minimally invasive nature. In such procedures, the usability and functionality of forceps are critical for surgical success. However, conventional methods require frequent replacement of different forceps during a single operation, increasing the burden on surgeons and affecting overall efficiency. This study aims to develop improved multi-functional laparoscopic forceps with an integrated switching mechanism. We identified the limitations of existing rotary and slide-type switching systems, such as oversized structures, unstable operation, and unreliable force transmission. To address these issues, we proposed a novel mechanism that enables manual selection of forceps through a sliding interface, followed by rotational fixation that simultaneously connects the transmission axis. This design reduces the outer diameter of the device from 40 mm to 9 mm and extends the stroke from 21 mm to 180 mm. Additionally, a newly developed locking mechanism ensures stable power transmission and operational accuracy. The proposed design contributes to the integration and miniaturization of surgical tools，reducing the physical burden on surgeons and improving the overall efficiency of laparoscopic procedures.
