Medical packaging is provided for enclosing a single-use medical device with multiple frangible operating lines and corresponding frangible connections to define a removable first end which reveals at the time of use an operative part forming the key part that is to come into contact with the patient. The remaining part of the device including the controlling part is retained in the rest of the packaging but can be used to control the device without hindrance. Each of the multiple frangible operating lines indicating on the packaging the difference between the key part that forms the operating part of the device for one of a plurality of predefined medical procedures wherein the identification of the frangible operating lines immediately educates and instructs the user in the correct usage in a sterile and clean manner.

Provided is a surgical dissector instrument including a pair of arms pivotably connected intermediate their ends, with each arm having a handle at one end, and a tooth formation at the other, wherein the tooth formations are mutually opposable and asymmetrical in profile.

Medical devices are disclosed. For example, a medical device includes an elongated member. The medical device includes a hole forming surface along a portion of the elongated member. The medical device includes an open cell element in physical communication with the elongated member. The open cell element is configured to house at least a first portion of a biocompatible substance.

A posterior spinal fusion system may include a plurality of cannulas that mate with cages polyaxially coupled to pedicle screws. The cannulas maintain access to the pedicle screws to facilitate percutaneous insertion of a fusion rod into engagement with the cages. Each cannula has a pair of blades that may be held together by an abutment member that at least partially encircles the blades. Each abutment member abuts the skin to define a variable subcutaneous length of the corresponding cannula. Each abutment members is also lockably removable from the corresponding blades to enable the blades to pivot with respect to the connecting element to a position in which they can be withdrawn from the connecting element. The blades of each cannula are spaced apart to provide first and second slots of each cannula, through which the fusion rod can be percutaneously inserted.

A deployable and flexible tooltip camera is provided for integration within a shaft of an endoscopic tool. The tooltip camera includes a camera mounted to a distal tip of a curved tube which is capable of rotational and translational movement to provide a wide field of view of a tooltip of the endoscopic tool during an endoscopic procedure. The tube retains its curved shape when in use to provide a unique perspective view of the tooltip, but can then be withdrawn into a shaft of the endoscopic tool such that the entire tooltip camera and tube are retained within the shaft of the endoscopic tool and can pass through a cannula. The curved tube may be formed of a super-elastic memory alloy like Nitinol and pre-shaped into an s-curve using a two-step heat treatment process to attain the necessary curvature, and further laser-patterned with holes to attain the necessary flexibility.

Various exemplary methods, systems, and devices for initializing a surgical tool are provided. In general, a surgical tool can include an end effector, an elongate shaft, and a wrist that couples the end effector to a distal end of the shaft. The wrist can be configured to facilitate movement of the end effector relative to the shaft. The surgical tool can include multiple flexible members configured to move, either individually or as a group including any plural number of the flexible members, to cause the movement of the end effector relative to the shaft by pivoting at the wrist. The movement of the end effector can include movement between an unarticulated position and an articulated position. The surgical tool can also include one or more homing members configured to be selectively actuated to force the end effector into the unarticulated position.

An apparatus comprises a first jaw, a second jaw, a first handle, and a second handle. The second jaw is pivotally coupled with the first jaw. The first jaw and the second jaw are configured to grasp tissue. The jaws provide offset electrode surfaces that are operable to deliver bipolar RF energy to tissue grasped between the jaws. The apparatus is further operable to sever tissue. A lockout feature selectively prevents tissue severing, based on an energization state of the jaws.

A rotatable jaw device for use with an endoscope and method of using a rotatable jaw device. The device includes a fork, and two jaws pivotally mounted to the fork. The jaws are movable between a predetermined closed position and a predetermined open position. At least one jaw has at least one protrusion on a surface of the jaw. The at least one protrusion prohibits movement of the two jaws in the opening direction beyond the predetermined open position. One jaw may have an elongated center void defined by twin jaw extensions, and the other jaw may rotate within the elongated center void when the two jaws move toward the predetermined closed position.
