Laparoscopic instruments are specialized tools used in laparoscopic surgery, comprising a series of precisely manufactured devices such as cameras, clamps, scissors, staplers, and others. These instruments are inserted into the abdominal cavity through a laparoscope, allowing surgeons to manipulate surgical operations via control handles while observing the surgical area through the camera, enabling endoscopic visual procedures. The most commonly used instruments include: dissecting forceps, atraumatic grasping forceps, toothed forceps, double-action scissors, needle holders, clip appliers, suction devices, and others. The basic structure of laparoscopic instruments mainly consists of the following parts: a functional metal tip at the head, a body insulated with non-conductive material in the middle, a rotating joint at the rear, and a handle at the tail for gripping. Above the handle, there is also a metal connector for attaching electrical or other energy-based devices.
The working principle of laparoscopic instruments is primarily based on the laparoscopic system. The laparoscopic system consists of visualization instruments and operational instruments. Visualization instruments transmit images of the surgical area to a display screen via a camera and imaging system, enabling surgeons to clearly observe the surgical field. Operational instruments, on the other hand, allow for the movement of surgical tools, such as the opening and closing of clamps or the cutting action of scissors, through the manipulation of control handles.
Laparoscopic instruments exhibit the following characteristics:
Minimally Invasive: Compared to traditional open surgery, laparoscopic surgery involves performing operations through small incisions or puncture ports, thereby reducing postoperative pain, recovery time, and the risk of complications.
Visual Advantage: Visualization instruments provide high-definition images, allowing surgeons to clearly observe the surgical area and perform operations with precision.
Flexibility: Laparoscopic instruments are ingeniously designed for flexible operation, enabling the completion of complex procedures within localized confined spaces.
Reduced Incisions: The specialized design of laparoscopic instruments requires only a few small incisions during surgery, minimizing trauma and postoperative scarring compared to the large incisions of traditional surgery.
Reduced Bleeding: Laparoscopic instruments offer effective hemostatic capabilities, minimizing blood loss during surgery.
