Abstract:
An endoscopic surgical instrument, comprising:a handle extended by an elongated tubular part, itself connected by a multidirectional joint to a terminal or distal part that carries a tool, a control means being provided in the area of said handle to control articulation of the terminal part through a mechanical wire or cable transmission, having a front end and a back end, passing inside the tubular part, also traversed by a central cable controlling tool, wherein the control means, located in the front part of the handle, comprises a spherical crown having a center and an axis, the spherical crown being orientable in all directions inside a cone relative to its center and being rotatable about its axis and is linked at an angle to a control part controlling the wire or cable transmission, and the proximal ends of the wire or cable transmission are attached to said control part, a transmission means to transmit the rotation of the spherical crown about its axis to an internal element rotatably mounted about the axis of the elongated tubular part, and rotation of this element is transmitted through said joint to the terminal part in order to orient the terminal part around its own lengthwise axis, and a locking means for non-permanent locking said joint at any angle.
