Provided is an instrument for surgery and, more specifically, to an instrument for surgery which can be manually operated in order to be used for laparoscopic surgery or various types of surgery.

An adapter assembly, for connecting a surgical reload to an electromechanical handle assembly, includes an outer tube; a trocar assembly releasably securable within a distal end of the outer tube, the trocar assembly including a trocar housing defining a pair of openings therein, wherein the pair of openings are in opposed radially extending relation to one another; and a trocar assembly release mechanism configured to releasably secure the trocar assembly within the outer tube. The release mechanism includes a pair of pins slidably supported within the outer tube, wherein each pin is selectively receivable within a respective opening of the pair of openings formed in the trocar housing; a release button supported in the outer tube and movable between an extended condition and a depressed condition; and a spring clip slidably supported in the outer tube, the spring clip interconnecting the release button and the pair of pins.

The release mechanism includes a release button supported in the outer tube and movable between an extended condition and a depressed condition; a spring clip slidably supported in the outer tube and connected to the release button; and a pair of lock cam pins supported within the outer tube, wherein each lock cam pin is secured to a respective leg of the spring clip, and wherein each lock cam pin is selectively receivable within a respective opening of the pair of openings formed in the trocar housing. The spring clip includes a backspan connected to the release button; and a pair of legs extending from the backspan.

An image-guided pharyngolaryngeal forceps assembly includes a pair of pharyngolaryngeal forceps and an image-guided device. The image-guided device is fixed on a body of the pair of pharyngolaryngeal forceps, is slender and flexible, and has a tube body, a camera module and a signal transmitter. The tube body is mounted along the body of the pharyngolaryngeal forceps. The camera module is connected to an end of the tube body near a jaw assembly of the pair of pharyngolaryngeal forceps, and has a lens and multiple LEDs. The signal transmitter, such as a connector or a wireless signal transmitter, is connected to an end of the tube body near a handle of the pair of pharyngolaryngeal forceps, and can transmit signals to an external device. The image-guided pharyngolaryngeal forceps assembly can capture and transmit real time images to an external device and can provide illumination during a pharyngolaryngeal surgery.

A robotic system includes a master device and a slave manipulator configured to support an instrument. The instrument includes an instrument shaft having a proximal end and a distal end, and an end effector coupled to the distal end. The instrument shaft is optionally configured to be inserted into an inserted position through a port so as to provide the end effector with access to a site. A control system is operably coupled to the master device and to the slave manipulator. In response to input at the master device, the control system controls the slave manipulator to move the instrument based on modeling the end effector as being positioned along a line coincident with a longitudinal axis of the distal end of the instrument shaft. The line does not intersect the port when the instrument shaft is in the inserted position through the port. Methods relate to robotic systems.

A surgical device capable of interconnecting to an external motorized hand pieces, bending a distal end segment, rotating a window element positioned distal to the distal end segment and rotating independently of it, and actuating a cutting element positioned within the outer window element and rotating independently of it.

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 can comprise a jaw assembly having atraumatic pads positioned thereon to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to movement of 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 is also able to utilize force stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue in scenarios where the tissue volume decreases while in the jaws.

A surgical tool can include a main unit and a first rigid sheath. The main unit includes an inner tube that is received within an outer tube. The first rigid sheath removably receives the main unit and connects to the main unit via a coupling between a first connector portion of the main unit and a second connector portion of the rigid sheath. The first rigid sheath can be completely removed from the main unit when the first connector portion is decoupled from the second connector portion. A different rigid sheath having a different shape from the shape of the first rigid sheath can then be removably attached to the main unit instead of the first rigid sheath. A surgical tool kit includes a plurality of rigid sheaths having different shapes and having the ability to be removably attached to the main unit.

A shaft for a micro-invasive surgical instrument includes a shaft tube with a proximal end portion and a distal end portion, a coupling device for detachable mechanical coupling of the shaft with a tool, and a rotation bearing, which mechanically connects the coupling device with the distal end portion of the shaft tube. The rotation bearing is configured in order to allow rotation of the coupling device with respect to the shaft tube about the longitudinal axis of the shaft on the distal end portion of the shaft.

A surgical tool including a housing having a proximal end and a distal end, a yoke disposed within the housing between the proximal end and the distal end, a handle pivotally coupled to the housing, and a pivot assembly coupling the yoke to the housing. The pivot assembly includes a first link having a first end and a second end. The first end of the first link is rotatably coupled to the housing and the second end of the first link rotatably coupled to a second link at a first end of the second link. The second link has a second end rotatably coupled to the yoke. The handle is coupled to the pivot assembly such that movement of the handle causes movement of the yoke.
