[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A double-jointed S-shaped sponge forceps for thoracoscopic surgery includes a forceps body, with a handle and a forceps head at each end. The forceps head has two clamping plates, one end of which is integrally formed with the forceps head, and the connection between the two is smoothly transitioned by a rounded corner. The other end of the clamping plate is arc-shaped. The forceps head includes a fixed jaw and a movable jaw that match each other. One end of the fixed jaw is fixedly connected to the forceps body, and one end of the movable jaw is hinged to the forceps body. The handle is connected to the movable jaw through the forceps body. The two clamping plates are symmetrical and respectively located at the other ends of the fixed and movable jaws.

[0008] The surgeon can control the opening and closing of the fixed and movable jaws via the handle, and clamp or release tissue using two clamping plates. The smooth, rounded transition at the connection between the clamping plates and the jaws, along with the rounded ends of the clamping plates, allows the jaws to smoothly penetrate the wound to clamp blood vessels. This prevents accidental injury to nearby blood vessels and tissues during insertion, effectively protecting surrounding blood vessels and tissues and improving surgical safety.

[0009] Preferably, the forceps body includes a handle rod and a jaw rod that are fitted together. The handle includes a fixed handle and a movable handle. The fixed handle is fixed to one end of the handle rod, and one end of the movable jaw is mounted on and hinged to the other end of the handle rod. The movable handle is mounted on and hinged to one end of the jaw rod, and one end of the fixed jaw is fixed to the other end of the jaw rod and fits into the movable jaw. A transmission structure is provided between the movable handle and the movable jaw. During surgery, the surgeon holds the fixed handle and the movable handle, and controls the rotation of the movable handle by moving their fingers. Under the transmission structure, the movable jaw rotates synchronously, thus achieving the opening and closing of the forceps head. Operation is simple and control is convenient.

The pin four is placed in the pin sliding groove two and the two are movably connected. When the pliers open, the movable handle is controlled by the fingers to open outwards, causing it to swing outwards relative to the handle rod around pin one. Simultaneously, pin two slides within pin groove one for a limiting position, pushing the jaw rod forward relative to the handle rod. This, in turn, causes the movable jaws to rotate relative to pin three, while pin four slides within pin groove two for a limiting position, thus achieving the opening action of the pliers. When the pliers close, the movable handle is controlled by the fingers to close inwards, causing it to swing inwards relative to the handle rod around pin one. Simultaneously, pin two slides within pin groove one for a limiting position, pushing the jaw rod backwards relative to the handle rod. This, in turn, causes the movable jaws to rotate relative to pin three, while pin four slides within pin groove two for a limiting position, thus achieving the closing action of the pliers. The operation is simple and convenient.

[0011] Preferably, the shape of the handle lever and the shape of the jaw lever are matched. Both the handle lever and the jaw lever are composed of line segment one, line segment two, and line segment three.
