A tool for installing and/or removing a protective cover of an instrument includes a body portion having an open end and a closed end. The open end defines an interior passage that extends into the body portion along a longitudinal axis of the body portion toward the closed end of the body portion. The interior passage is configured to receive at least a portion of the protective cover in the interior passage. One or more members are connected to the body portion, and each of the one or more members includes a free end movable relative to the body portion. Systems and methods relate to tools for installing and/or removing protective covers of instruments.

Removable catheter cap, and applications thereof, for delivering medical tubes in bodily passages. Removable catheter cap covers flexible medical tube (e.g., catheter) distal tip during delivery in a body lumen. Catheter cap includes: cap body removably connectable to, for capping, catheter distal tip, and transformable into a predefined constituent part freely passable through catheter lumen; and cap releasing member extending through catheter proximal end when catheter cap is connected to the catheter, and manipulatable for transforming cap body into constituent part or/and for withdrawing constituent part from catheter distal tip through catheter lumen. Exemplary applications are: provision of a catheter assembly including a catheter and the removable catheter cap connected thereto; a medical kit including one or more catheters and one or more correspondingly configured removable catheter caps; and a method for delivering a catheter in a blood vessel of a subject, for example, via an over-the-wire technique.

A retractor mounting assembly including an end-effector having a body extending between first and second faces. The first face is configured for attachment to an interface plate on the robotic arm of a surgical robot. The second face defines an arm mount. An arm extending between first and second ends with the first end configured for attachment to the end-effector arm mount and the second end providing a retractor mount configured for supportive attachment of a retractor.

A tissue dissector includes a handle assembly including an actuator, a head portion including a blade member defining an aperture configured to receive tissue therethrough, and a lighting assembly configured to provide lighting to the aperture of the blade member. The blade member is operatively coupled with the actuator for rotation about the aperture.

A handle assembly of a hand-held surgical instrument includes a motor and an actuation trigger. Clamping and/or stapling tissue may be carried out by actuation of the trigger. The motor may be activated to assist the manual actuation of the trigger. The handle assembly may include distinct gears for effecting discrete functions of an attached end effector.

A surgical instrument for applying fasteners includes a drive motor, a replaceable loading unit having an end-effector assembly, and an adapter configured to releaseably couple a replaceable loading unit to the drive motor. The adapter includes a strain gauge having a drive circuit coupled thereto. The strain gauge and the drive circuit are configured to directly measure a driving force in the adapter.

A surgical device including a handle assembly, an elongated portion, an end effector, a drive shaft, and a wick is disclosed. The wick is disposed within an outer sleeve of the elongated portion and is made from a fibrous material. The wick is configured to transfer moisture from a first portion of the wick to a second portion of the wick.

A reamer head assembly comprising: a base member supporting a reaming member, the reaming member comprising a reaming member configured to ream bone; wherein the reaming head assembly comprises a plurality of recesses arranged about the reaming surface, the plurality of recesses configured to allow manual gripping of the reaming head assembly.

An instrument and method for placement of vascular grafts. Embodiments of the instrument comprise an elongated shaft, a clamp and a tip. The shaft includes a distal end portion, a proximal end portion, and optionally a handle at the proximal end portion. The clamp and/or the shaft are configured to removably couple the clamp to the distal end portion of the shaft. The tip and/or the instrument are configured to removably couple the tip to the instrument. In embodiments the tip covers the clamp.

A biopsy device includes a cannula and a specimen collector. The cannula has a proximal end and a longitudinal axis. The specimen collector contains the proximal end of the cannula. The specimen collector has a removable sample receiving cartridge that is removable along the longitudinal axis of the cannula to expose the proximal end of the cannula.
