An electromechanical surgical device includes a motor system configured to drive drive-shafts and a steering cable arrangement. A control system may be provided for controlling the motor system. A remote control unit may also be provided for controlling the motor system via the control system. Optical or Hall-effect devices, may be provided for determining the position of the elements of the surgical instrument based on the detected rotation of the drive-shafts. A memory unit stores a plurality of operating programs or algorithms, each corresponding to a type of surgical instrument attachable to the electro-mechanical surgical device. The control system reads or selects from the plurality of operating programs or algorithms, the operating program or algorithm corresponding to the type of surgical instrument attached to the electromechanical surgical device.

Electro-mechanical surgical device

A neuromonitoring needle electrode placement gun which includes a housing, at least a first needle electrode and housing assembly, an elongated channel dimensioned and configured for accommodating axial movement of the at least a first needle electrode and housing assembly within the channel and for directing movement of the at least a first needle electrode and housing assembly and a pusher dimensioned and configured for engaging the at least a first needle electrode and housing assembly and for axially displacing the at least a first needle electrode and housing assembly.

Method for placement of neuromonitoring needles

A surgical device including a first jaw and a second jaw is presented. The surgical device also includes a biasing element that biases the distal end of the first jaw towards the distal end of the second jaw. The device also includes a first driver disposed in the second jaw and coupled to the first jaw. The first driver is configured to cause separation of the first jaw and the second jaw. The device further includes at least one of a cutting element and a stapling element disposed within the second jaw, preferably a blade rotatably mounted on a wedge. A second driver is configured to move the cutting element and/or the stapling element proximally from a distal end toward the proximal end of the second jaw to at least one of cut and staple a section of tissue disposed between the first and second jaws.

Surgical device

Neuromonitoring needle-cartridge gun system

A surgical device is described. The surgical device may comprise a rotatable cutter configured to cut tissue for insertion of a cannula, and a first driver configured to be driven by a motor arrangement and to rotate the cutter. The surgical device may further include, for example, the cannula, at least one of the rotatable cutter and the first driver being disposed in a bore of the cannula. In one embodiment, the rotatable cutter may include an auger having a cutting thread. In another embodiment, the rotatable cutter may include a disk-shaped blade.

Trocar device

Coupling assemblies are provided for maintaining a secure connection between surgical devices utilizing a shaft-and-pinion configuration and powered drive shafts. The coupling assemblies include a clip to be disposed without or within a pinion for receiving and securing a drive shaft member. The coupling assemblies are designed to maximize restriction of movement between the drive shaft and clip, but avoid impeding the rotational motion of a pinion.

A surgical device includes a first jaw and a second jaw disposed in opposed correspondence with the first jaw. The second jaw is mechanically coupled to the first jaw at a proximal end opposite a distal end. A cutting element is disposed within the second jaw, and a first driver is configured to move the cutting element proximally from the distal end toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws.

A flexible shaft includes a flexible, elongated outer sheath, at least one drive shaft disposed within the outer sheath and a moisture sensor disposed within the outer sheath configured to detect moisture within the outer sheath. Another flexible shaft includes a flexible, elongated outer sheath, at least one flexible drive shaft disposed within the outer sheath and a coupling connected to a distal end of the outer sheath configured to couple to a surgical attachment. A sleeve includes an elongated shaft configured to receive a flexible shaft therein and a securing arrangement configured to selectively and variably retain the elongated shaft in any one of a number of longitudinal positions along the flexible shaft. A surgical system includes an electro-mechanical driver, an elongated, flexible sheath, at least one drive shaft disposed within the flexible sheath, a surgical attachment coupled to the at least one drive shaft, the electro-mechanical driver configured to drive the surgical attachment, a shape-retaining sleeve, at least a portion of the flexible sleeve being disposed in the shape-retaining sleeve, the shape-retaining sleeve configured to maintain the at least portion of the flexible sheath in a predetermined shape, and an arrangement variably securing the shape-retaining member to the flexible sheath in any one of a number of longitudinal positions along the flexible sheath.

Couplings for interconnecting components of an electro-mechanical surgical device

A surgical device includes a first jaw and a second jaw in opposed correspondence with the first jaw. A first driver is configured to cause relative movement of the first jaw and the second jaw in a plane. The first driver is configured to engage a drive shaft rotatable about a rotation axis arranged in non-parallel, e.g., perpendicular, correspondence to the plane. The device may also include a surgical member, e.g., a cutting and stapling element, disposed within the first jaw. A second driver is configured to cause relative movement of the surgical member in a direction parallel to the plane. The second driver is configured to engage a drive shaft rotatable about a rotation axis arranged in non-parallel correspondence to the plane.

A surgical device includes a first jaw and a second jaw disposed in opposed correspondence with the first jaw. The second jaw is mechanically coupled to the first jaw at a proximal end opposite a distal end. A cutting element is disposed within the second jaw, and a first driver is configured to move the cutting element proximally from the distal end toward the proximal end of the second jaw to cut a section of tissue disposed between the first and second jaws. The device may also include a stapling element disposed within the second jaw. The cutting element and the stapling element may be contiguous so as to define a cutting and stapling element, such as a wedge having a blade disposed thereon.
