The invention is an ergonomic laparoscopic instrument which provides a better comfort to the operator during long stretches of usage. The device consists of a uniquely shaped handle with finger and palm grippers and buttons to perform specific functions using the shaft and the head attached to it. The grips are specially designed to fix the device in the palm of the surgeon comfortably and allow them to relax or do stretching of fingers without putting the device down. The handle consists of a series of buttons and rotating knobs for manipulating the shaft and the head that is attached at its end. The head attached can also be locked at any angle using a mechanism provided inside the handle. The button operated gripper function improves comfort and reduces the stress on the upper extremities.

Though laparoscopic surgery came as a boon to mankind due to various benefits attached to it, the surgeons who do the surgery have to deal with a lot of bodily stress and discomfort while doing the surgery. The surgery requires making small incisions in the body which are used to see the internal organs through camera feedback on a big video output device. So, the surgeon has to continuously look into the video output device to perform the operation, causing pain in the upper extremities. The devices that are used for surgeries are also not ergonomically designed, causing numbness and pain in the hand and upper extremities. Thus, there is a need for an ergonomically designed laparoscopic surgery equipment that relieves the physical stress on the operating surgeons.
- Ergonomic instrument design: the design puts less stress on the hands and upper extremities, decreasing numbness and cramps during long hours of surgeries
- Specially designed grip: the handle of the instruments grips the palms of the surgeon, which allows them to stretch their fingers without the device falling off
- Ease of usability: the instruments has relevant color coding assigned to different instruments, segregated based on their different functions
The patent describes a fully designed laparoscopic instrument with finger and palm grippers, multiple control knobs, and a shaft assembly allowing complex movements of the surgical head. The internal mechanical linkages are defined with gears, shafts, and buttons. There is mention of physical configurations like a C-shaped palm gripper and elastic finger jaws, implying a physical prototype was developed for functional testing and ergonomic fit, though no clinical testing is explicitly mentioned.
The technology presents an advanced ergonomic laparoscopic surgical instrument designed to reduce surgeon discomfort during operations. It addresses key problems with conventional tools by improving handle grip, function placement, and reducing strain on hand nerves. The invention is fully conceptualized and mechanically described.

Decreasing the stress on surgeons during laparoscopic surgery makes the surgery more efficient, decreases risk of infection and mistakes and makes the surgery safer
This invention is applicable in domains involving laparoscopic and minimally invasive surgeries. It can be used by surgeons in hospitals and surgical centers to perform abdominal and pelvic operations more comfortably. The ergonomic design reduces surgeon fatigue, enabling better focus and performance during long and complex procedures.
