Described is a surgical device to retain and move an organ during surgical operations, which makes it possible to easily prepare the system for holding the organ and avoids the need both for a dedicated access trocar for exclusive use and the insertion of an operating member connected irreversibly to the surgical device. The surgical device minimises the risk of tearing and/or bleeding of the organ following the actions applied on the same organ during the surgical operation.

A surgical tool and related methods are provided for removal of a bone sliver from a resected joint. The tool can include a housing including an upper end, a lower end, and a channel extending from the upper end to the lower end. A paddle member extends from the lower end of the housing. The paddle member includes a paddle shaft and a paddle head. The surgical tool further includes an insertion member that has a handle end, an extension that extends from the handle end, and a cutting tip. The extension is translatable within the channel such that the handle end and the cutting tip can move relative to the housing between a retracted position and an advanced position.

A handle assembly for actuating an end effector includes a feedback mechanism for providing an audible and/or tactical response to indicate to the user that the handle assembly is fully actuated. The feedback mechanism may include a hammer member configured to strike a surface of the handle assembly to create the audible and/or tactical response.

A method of facilitating access to a neonate through a caesarean incision in the woman's abdomen by opening the incision, includes providing a supporting ring dimensioned to allow delivery of a neonate through the ring and comprising a non-adjustable pelvic-region retractor and handle fixed to the supporting ring and articulating the supporting ring to insert the non-adjustable pelvic-region retractor into the incision to cover and hold back the woman's bladder with the supporting ring disposed over the woman's abdomen. A first adjustable saddle-shaped retractor is then inserted into the incision to cup a first section of abdominal tissue on an abdominal side of the incision, before attaching the first adjustable saddle-shaped retractor to the supporting ring while it is cupping the first section of abdominal tissue at a first position spaced apart from the non-adjustable pelvic-region retractor to anchor the supporting ring to the woman and partially open the incision.

An apparatus for removing a hook embedded within a tissue is presented. The hook has a barb extending from a point section of the hook. The apparatus includes a clamping device configured to secure the hook. A probe is coupled to the clamping device. The probe has a tip portion configured to fit within a space between the barb and the point section of the hook to allow the hook to be removed from the tissue.

A hand grip apparatus for receiving operator input includes a body having a proximal end and a distal interface end for coupling to an input apparatus. A first control lever is attached to the body and extends away from the proximal end and terminates in a finger grip for receiving one of the operator's fingers. A second control lever is attached to the body and extends away from the proximal end terminating in a thumb grip for receiving the operator's thumb. Movement of at least one of the control levers is operable to produce a first control signal representing the movement. An input control is included on the body between the grip ends and has an actuator surface angled towards the finger grip end and configured to produce a second control signal in response to actuation by one of the operator's fingers.

A knob assembly and a circular stapler are provided. The knob assembly includes a knob driver, a knob body, a first cooperating component and a second cooperating component. In a blocking state, the first cooperating component is linked with the second cooperating component; while in an unblocking state, the first cooperating component is not fixedly linked with the second cooperating component. One of the first cooperating component and the second cooperating component is provided at the knob driver and the other one is provided at the knob body. When the knob driver is rotated, if a rotating resistance to the knob body reaches a preset resistance value, the knob assembly cannot transmit larger torque, therefore the knob assembly is in a failure mode, the position of the anvil assembly relative to the cartridge remains unchanged, and the tissues will not be excessively compressed.

Handheld gas spray systems for mixing and dispensing multi-component compositions.

A disposable surgical instrument includes an instrument grip forming a receiving housing. A separate handle is mounted in the instrument grip in the manner of a rocker. A shaft tool includes a shaft having at least two relatively axially movable bar or rod components and an instrument head having patient engagement elements which can be actuated by the bar or rod components, of which one bar or rod component is fixed at the proximal end thereof to the instrument grip and the other bar or rod component has an articulation point on which the handle is directly articulated in such way that a manually actuated rocker movement of the handle about the articulation point on the handle side is transformed directly into an axial movement of the other bar or rod component on the articulation point on the shaft side.

A surgical instrument includes a gripping assembly, a shaft assembly, an end effector, and a pivoting member. The gripping assembly defines a first opening for receiving a finger or a thumb of a user. The gripping assembly includes a first deformable feature that is configured to be moved in order to increase or decrease a cross-sectional area of the first opening. The shaft assembly extends distally from the gripping assembly. The end effector is positioned at a distal end of the shaft assembly and includes a first member. The pivoting member is pivotably coupled with the shaft assembly. The pivoting member is pivotable with respect to the first member of the end effector between an open position and a closed position to thereby clamp tissue between the first member and the pivoting member.
