A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

A surgical instrument unit includes a shaft having an end effector at the tip end, a hollow base, and a strain generating part that supports a root part of the shaft in the base. The strain generating part has a first-layer strain generating body and a second-layer strain generating body arranged in order in a long axis direction of the shaft, each of the first-layer strain generating body and the second-layer strain generating body including a multidirectional strain generating body supporting a root part of the shaft with a plurality of legs. The first strain generating body is inclined by a predetermined angle θ with respect to a plane orthogonal to a long axis of the shaft, and the second strain generating body is inclined by an angle−θ opposite to each leg of the first strain generating body with respect to the plane.

A treatment tool includes: a pair of grippers configured to grip living tissue, at least one of the pair of grippers being configured in an openable and closable manner; a transmission portion connected to the at least one of the pair of grippers, the transmission portion being configured to move forward and backward along a first direction to open and close the pair of grippers; an operating portion configured to receive user operation for gripping the living tissue; an elastic body configured to transmit, to the transmission portion, an operating force applied to the operating portion by the user operation while being compressively deformed in accordance with the operating force; and an adjustment mechanism configured to adjust an amount of compressive deformation of the elastic body when the user operation is performed on the operating portion, to thereby adjust a gripping force of the pair of grippers.

A handheld microsurgical robot according to an embodiment of the present disclosure includes a tool, and a driving mechanism configured to detachably fix the tool and operate the tool, wherein the driving mechanism includes a platform supporting the tool, a plurality of driving assemblies connected to the platform and configured to operate the platform; and a base configured to fix the plurality of driving assemblies, wherein each of the plurality of driving assemblies is capable of a linear motion with respect to the base and is capable of a rotational motion with respect to the base, wherein a position and an angle of the platform with respect to the base are controlled by the linear motion of each of the plurality of driving assemblies.

A surgical device includes an adapter assembly that selectively interconnects a loading unit and a device housing. The adapter assembly includes a drive converter assembly for interconnecting a rotatable drive shaft and an axially translatable drive member of the loading unit. The drive converter assembly converts and transmits a rotation of the rotatable drive shaft to an axial translation of the axially translatable drive member of the loading unit. The drive converter assembly includes a drive element, a drive nut, and a distal drive member. The drive element defines a longitudinal axis. The drive nut is disposed about the longitudinal axis, and the distal drive member is disposed along the longitudinal axis.

A surgical instrument is provided having an actuator mechanism with an integrated extension element. The surgical instrument comprises a handle assembly, an elongate shaft, and an end effector. The end effector comprises a jaw assembly having atraumatic pads to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to a movable handle of the handle assembly. The actuator can have an integrated extension element that allows the actuator to translate within the elongate shaft upon application of a relatively low force and translate and extend upon application of a relatively higher force to the actuator to limit the force applied by the jaw assembly. The actuator also utilizes forces stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue when the tissue volume decreases while in the jaws.

Methods for selectively attaching a shaft assembly to a handle of a surgical instrument and an arm of a surgical robot are disclosed.

The invention relates to a medical instrument having a hollow shaft, whose proximal end can be connected to an operating unit and having a tool tip arranged at the distal end of the shaft having a tool arranged at the distal end of the tool tip, wherein the tool has two jaw parts, which can be pivoted relative to one another and wherein the jaw parts are pivoted via actuating elements, which are mounted so as to be axially displaceable in the shaft and which can be actuated on the proximal side via the operating unit and wherein the tool tip can be pivoted via a joint mechanism relative to the longitudinal axis of the shaft.

In order to provide a medical instrument, which ensures a uniform transmission of tensile and compressive forces even via the pivot region to the tool tip, it is proposed according to the invention that the pivotable jaw parts are each coupled via an articulated drive element to the distal end of an actuating element mounted so as to be axially displaceable in the shaft such that the articulated drive element spans the region of the joint mechanism between the distal end of the shaft and the proximal end of the tool tip.
