Tunable microwave ablation probe
10028787 · 2018-07-24 · ·

An electromagnetic surgical ablation probe having a tunable helical antenna element includes a coaxial feedline having an inner conductor coaxially disposed within a dielectric, and an outer conductor coaxially disposed around the dielectric. The inner conductor and dielectric extend distally beyond a distal end of the outer conductor. A helical antenna element is operably coupled to a distal end of the inner conductor. During use, the antenna may be tuned by changing at least one dimension of the helical antenna element. Embodiments are presented wherein a dimension of the helical antenna element is changed by state change of a shape memory alloy, by a change in temperature, by activation of a piston by fluidic pressure, by linear motion of a conical tip, and by a manual screw-type adjustment.

This disclosure includes needle holders and related methods. Some holders use or include an elongated handle having a proximal portion and a distal portion, a first jaw member coupled to the distal portion of the handle, a second jaw member pivotally coupled to the first jaw member, and a lever pivotally coupled to the handle and coupled to the second jaw member such that the lever can be actuated by a user's thumb to selectively open and close the jaw members. In some holders, the handle extends proximally beyond the lever such that the lever can be actuated by the user's thumb to selectively open and close the jaw members while the handle is grasped within the user's hand. In some holders, the handle is defined by an elongated housing defining an interior volume configured to receive at least a portion of the lever when the jaw members are closed.

Devices and methods for breaking and retaining surgical reduction tabs

Various devices and methods for breaking and retaining surgical reduction tabs are provided. In general, the devices and methods can allow a single surgical instrument to break a plurality of surgical reduction tabs off one or more surgical implants and retain the broken tabs within the instrument. In an exemplary embodiment, a surgical instrument can include an opening at a distal end thereof that is configured to receive a surgical reduction tab therein when the tab is connected to a surgical implant. A retention element at least partially disposed within the instrument can be configured to engage the tab received in the opening so as to hold the tab securely within the instrument. With the tab received in the opening and held by the retention element, the surgical instrument can be configured to be manipulated to break the tab off the surgical implant. The broken tab can be retained within the surgical instrument by being held therein by the retention element. The instrument can be repeatedly relocated and repeatedly break off surgical reduction tabs of one or more surgical implants, with each successive tab received in the opening displacing the immediately preceding broken tab from the retention element such that a chamber formed in the instrument can simultaneously hold a plurality of broken tabs within the instrument.

Axially reciprocating microsurgical instrument with radially compressed actuator handle
09592074 · 2017-03-14 · ·

A microsurgical instrument has a pair of operative surgical surfaces that are moved relative to each other in shearing or grasping procedures performed by the instrument. The instrument has a handle containing an elongate center rod with a ring mounted for reciprocating movement on the rod. A tube is secured to the ring and a shaft extends through the tube and is secured to the rod. The handle also includes a plurality of resilient arms that extend along the length of the rod and engage against a sliding surface of the ring on the rod. The plurality of actuator arms are alternatively manually compressed radially inwardly by the surgeon's hand and released by the surgeon's hand to allow the arms to flex radially inwardly and outwardly. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod and causes the tube and shaft to move axially relative to each other.
