This utility model relates to the field of surgical instrument technology, and in particular to a laparoscopic minimally invasive surgical forceps, comprising a long rod, one end of which is fixedly provided with a holding component, and the other end of which is provided with a clamping component connected to the holding component. A spreading component is sleeved on the outer wall of the long rod. The spreading component includes a sleeve sleeved on the long rod, one side of which is provided with a fixing ring fixed to the long rod.

The present invention relates to a robotic system (100) for laparoscope (6) manipulation during minimally invasive surgeries. The system comprises a movable base (1), a vertical column (3) with a curved configuration to shift the centre of mass for stability, and a SCARA system (4) that cooperates to align the Remote Center of Motion (RCM) (5).

This invention belongs to the field of medical robotic arm technology, and more particularly to a needle-holding robotic arm for minimally invasive surgery, comprising a handle, a protective shell, and a crank shell. The invention features an anti-tipping wheel located inside the crank shell near the shaft. The rim of this anti-tipping wheel presses firmly against the surface of the wire rope, effectively preventing the wire rope from slipping out of the groove in the reel during high-speed or large-angle transmission. This ensures that the gripper's movements are consistent with the surgeon's intentions, avoiding missed steps due to skipped threads or slack, thereby improving the safety and precision of the surgery. Simultaneously, the wire rope is driven by gear transmission inside the protective shell, and the pitch axis controls the pitch angle of the gripper. This allows the surgeon to control the opening and closing of the gripper and the pitch angle simultaneously or separately through a single finger gripping operation, enabling complex actions such as needle clamping, needle rotation, and suturing within confined human cavities. This significantly improves the instrument's operational flexibility and surgical efficiency.

A robotic system for minimally invasive surgery includes a robotic arm with robotic F / T sensors and surgical instruments attached thereto. The surgical instruments are positioned within a patient's body cavity via a cannula in which a cannula F / T sensor is integrated. The output of the cannula F / T sensor is subtracted from the output of the robotic F / T sensor (and vice versa) to eliminate the influence of force or torque between the cannula and the patient's skin, obtaining only the force or torque applied to the surgical instruments. To perform this subtraction, the reference frames of the two F / T sensors are first aligned. For example, the position of the surgical instrument tip can be measured or estimated, and the corrected force or torque can be similarly converted to the reference frame of the surgical instrument tip.
