TL;DR: In this paper, a four-jawed combinational scissor-grasper surgical tool for use in laparoscopy is described. But this tool is not suitable for use with a human operator.
Abstract: Disclosed is a four-jawed combinational scissor-grasper surgical tool for use in laparoscopy. Cutting and grasping functionalities are respectively enabled via movement of a pair of such specially contoured jaw members sliding against or splaying apart from the other pair. Also disclosed are means for achieving selectable interlocking of jaw members and mechanical linkage for their actuation by human user.

TL;DR: In this paper, a surgical tool with an elongated shaft having a proximal end and distal end is described, where an effector body includes a plurality of motor interfaces for driving the plurality of effector mechanisms.
Abstract: A surgical tool having an elongated shaft having a proximal end and distal end. A surgical end effector is located about the distal end. The surgical end effector has a plurality of effector mechanisms comprising a plurality of degree of freedoms. An effector body is located at the proximal end. The effector body includes a plurality of motor interfaces for driving the plurality of effector mechanisms. A transmission is coupled to the effector body

TL;DR: An implant insertion system includes a shape memory implant movable between a first shape a second shape and an implant insertion device movable from an implant disengagement position to an implant engagement position as mentioned in this paper.
Abstract: An implant insertion system includes a shape memory implant movable between a first shape a second shape and an implant insertion device movable between an implant disengagement position and an implant engagement position. The implant insertion device receives the shape memory implant in its first shape while in its implant disengagement position. Movement of the implant insertion device from its implant disengagement position to its implant engagement position manipulates the shape memory implant from its first shape to its second shape. The implant insertion device maintains the shape memory implant in its second shape until delivery of the shape memory implant into tissue or bone.

TL;DR: In this article, a modular IOL system including a base and a lens, wherein the lens includes fixed and actuatable tabs for connection to the base, is presented, allowing for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or postoperatively.
Abstract: Modular IOL systems including a base and a lens, wherein the lens includes fixed and actuatable tabs for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or post-operatively. Drug delivery capabilities and/or sensing capabilities may be incorporated into the base. Injector devices may be used to facilitate placement of the base and the lens sequentially or simultaneously into the eye.

TL;DR: In this article, the authors describe a wrist-like instrument with three degrees of freedom for actuation of the end effector and a configurable set of arms which are capable of performing a first function in one mode and a second function in a second mode.
Abstract: The present invention is generally related to the art of surgical instruments for use in minimally invasive surgery and more specifically to robotic laparoscopic surgery. According to one aspect of the invention, this articulated instrument is capable of producing a wrist-like motion, i.e. the end effector generally has three degrees of freedom. Additionally, it also has another degree of freedom for actuation of the end effector. The end effector has a configurable set of arms which are capable of performing a first function in a first mode and a second function in a second mode. This end effector also has the capability to dynamically switch between two modes of different functions (e.g.: scissor and grasper). These actions of switching back and forth between the different modes (e.g.: scissor and grasper) can be described as extra actions. These extra actions are achieved without increasing the number of inputs.

TL;DR: In this paper, a locking tip cover (410) was used to lock the disposable tip assembly to a lock interface element (448B) of a tip interface (245) of the reusable instrument portion (204).
Abstract: A surgical instrument (203) includes a reusable instrument portion (204) and a disposable tip assembly (205). The disposable tip assembly (205) includes an end effector assembly (206) that in turn includes an end effector. The disposable tip assembly (205) also includes a locking tip cover (410) that locks the disposable tip assembly (205) to a lock interface element (448B) of a tip interface (245) of the reusable instrument portion (204). To facilitate mounting the disposable tip assembly (205) on the tip interface (245) of the reusable instrument portion (204), the disposable tip assembly (205) includes a first quick connect/disconnect element (409) and the tip interface (245) includes a second quick connect/disconnect element (447). The second quick connect/disconnect element (447) is coupled to a tendon (452). The tendon (452) is also coupled to an actuator assembly that provides forces that push and pull (push/pull) the tendon.
