Ergonomic support units for use with medical instruments, such as surgical forceps. In various implementations the support units may include wings, rings, winged rings, or other support structures. An ergonomic instrument including a first support unit shaped to support at least one finger of a user and a second support unit shaped to support a thumb of a user, wherein the first support unit and second support unit are configured to reduce effort required to manipulate the ergonomic instrument.

Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a shaft having a distal end, a proximal end and a longitudinal axis extending between the distal end and the proximal end, wherein the shaft comprises a flexible portion and an articulating portion, wherein the flexible portion extends distally from the handle assembly and the articulating portion extends distally from the flexible portion, and further wherein the articulating portion is configured to articulate relative to the flexible portion; a handle assembly attached to the proximal end of the shaft; and an end effector attached to the distal end of the shaft; wherein a plurality of articulation cables extends from the handle assembly to the articulating portion, such that when tension is applied to at least one of the plurality of articulation cables, the articulating portion bends relative to the flexible portion of the shaft; wherein the plurality of articulation cables are mounted to the handle assembly such that moving the handle assembly to angle the handle assembly relative to the longitudinal axis of the shaft applies tension to at least one of the plurality of articulation cables, whereby to articulate the articulating portion of the shaft relative to the flexible portion of the shaft.

A mechanically ungrounded master control device comprises a rigid chassis for engagement with one or more fingers of a user's hand and at least one pivotable finger engagement device for controlling movement of a tool end effector. The control device also includes at least one sensor for detecting a position and orientation of the rigid chassis in a surgical environment and a switch coupled to the rigid chassis and manipulatable by a finger of the user's hand while another finger of the user's hand is engaged with the at least one pivotable finger engagement device.

The present disclosure provides flexible medical scissors, including a main body, a lifting mechanism, an adjusting mechanism, a flexible sleeve, and a shearing mechanism. The flexible medical scissors provide the lifting mechanism at a top of a handle, the finger sleeve in the lifting mechanism sleeves a ring finger of a user, when using, the finger sleeve is pulled to enable the pull rope to pull the rotating shaft, and the rotating shaft drives the movable cutter to rotate, so that a shearing function is realized. The adjusting mechanism is disposed at a bottom of the handle, three groups of sliding grooves are formed in the adjusting mechanism, and sliding columns are respectively disposed in the sliding grooves.

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.

A single-patient-use disposable tool comprises a molded, single-piece body with a curved upper surface having a predetermined bend radius for bending a needle slidably disposed in a sheath. A distal end of the curved surface has a slot for insertion of a tip of a needle, while the proximal end of the curved surface has a guide member for slidably receiving the sheath. Two finger loops or similar ergonomic features allow the user to rotate the bending tool relative to the sheath to bend the needle about the predetermined bend radius. After completing the bend, the tool is removed from the needle and disposed of.

The present disclosure provides a bioresorbable foam closure device for trans-nasally closing an opening in a base of a skull. The closure device comprises a phase-separated polymer having a porosity of greater than 80%. The device includes a stem portion having a proximal end and a distal end, and a head portion at the distal end of the stem portion. The closure device is deformed from a free shape to a constricted shape, inserted through a nasal cavity and into the opening, and released to at least partially revert back to the free shape such that the stem portion fills the opening and the head portion abuts cranium and dura to secure the closure device in position and seal the opening.

Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system may include one or more markers implantable within or around the target tissue region, and a probe for transmitting and receiving electromagnetic signals to detect the one or more markers. During use, the marker(s) are into a target tissue region, and the probe is placed against the patient's skin to detect and localize the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the localization information from the probe.

Disclosed is a suture delivery device for endoscopically passing a suture into biological tissue. The device can include two hypodermic needles that can be manipulated via controls on a handle of the device in order to pass a suture from one needle to the other. For example, the device can include a first needle coupled to at least one loop member that, when deployed from the first needle, provides a target through which a second needle of the device can deliver the suture. Once the second needle intersects the loop member, the user can advance a length of suture out through a distal end of the second needle. The loop member can then be retracted into the first needle, thereby grabbing and securing the suture in the process.

Disclosed herein are systems and methods for insertion tools for implanting electrode leads. In one embodiment, an insertion tool comprises a shaft having an outer cannula and an inner cannula. An actuator may be configured to transition the insertion tool between at least three configurations. In a first configuration, the inner cannula and the outer cannula are configured to receive the lead in the shaft. In a second configuration, the inner cannula and the outer cannula are configured to secure the lead in the shaft. In a third configuration, the inner cannula and the outer cannula are configured to cause the lead to separate from the insertion tool and implant in adjacent tissue.
