A vein harvesting device is disclosed. The vein harvesting device includes a handle assembly, at least one elongated portion, first and second end effectors, and a tip. Each end effector is disposed adjacent a distal portion of the at least one elongated portion. Each end effector includes a first jaw member and a second jaw member, and at least one jaw member is movable toward the other jaw member. The tip is disposed in mechanical cooperation with the elongated portion. A distal end of the tip extends distally beyond a distal-most end of the first end effector. The first end effector is movable independently of the tip, and the second end effector is movable independently of the tip.

A hemostasis pressure device is disclosed. In one embodiment, the hemostasis pressure device includes a reusable component and a disposable cuff. The disposable cuff includes a pre-inflated pad configured to be placed at an access site on a patient. A knob secured to the reusable component is configured to control the pressure applied to the pre-inflated pad, providing incremental, fine-tuned control of pressure applied to the access site to achieve patent hemostasis.

Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.

A retractor/protector suitable for use in a surgical incision or a natural orifice comprises a longitudinal axis defining an instrument access channel extending from a proximal end to a distal end; a flexible outer ring; an inner ring; a flexible sheath extending between the outer ring and the inner ring; and at least one rigid segment adapted to attach to the flexible outer ring to thereby increase the rigidity of the outer ring. Embodiments of the retractor/protector are described that have interlocking and non-interlocking rigid segments. Embodiments are also described that have bases that insert into or under the flexible outer ring in addition to or in lieu of rigid segments to increase rigidity and/or provide support for a detachable cap.

A surgical clip application device for applying and crimping surgical clips to ligate a vessel.

A semi transparent nitrile glove comprising nitrile latex, caustic alkali, accelerators, vulcanizing agents, stabilizer and antifoaming agent, wherein the nitrile latex is any one selected from either acrylonitrile butadiene copolymer or carboxylated acrylonitrile butadiene copolymer, wherein the caustic alkali is a combination of either potassium hydroxide and ammonia or sodium hydroxide and ammonia, wherein the accelerators are chemical compounds of dithiocarbamates, wherein the vulcanizing agents are selected from both ionic and covalent vulcanizing agents, wherein the stabilizer is any one of either sodium dodecylbenzene sulfonate or sodium dodecyl sulfate and wherein the antifoaming agent is any one from a group consisting of silicone based antifoam, non-silicone based antifoam, oil based antifoam and water based antifoam wherein the semi transparent glove is without pigment and without titanium dioxide.

Systems, devices and methods to improve safety and efficiency in an operating room comprise providing a suture package that holds new suture needles and needle receptacles for storing used needles. The devices can be safely worn for the surgeon to self-dispense new suture needles in the near surgical field and to secure the used needles into a needle trap or a needle retainer located on his extremity, on his operative instruments or on the surgical drapes. The device may provide automated and/or simplified needle counting both during use and after removal from the surgical field. The device may be configured for ergonomic and efficient use so as to minimize the actions and motions of the surgeon to dispense and secure the needle.

A ligation clip cartridge includes a housing and one or more retaining members. The housing defines a plurality of clip recesses that receive ligation clips. The retaining members are positioned on the housing to engage the clips within the housing in an unbiased state to minimize damage to the clip material caused by strain on the clip.

The invention provides a bone cement mixing assembly including a mixer, a syringe barrel and a movable plug cover. The mixer includes a stirring rod and a stirring barrel. The stirring rod has holding end, a rod body and a stirring end. The stirring barrel has a barrel cover, a first barrel open, a first barrel body, a first barrel bottom, and a stirring space located in the first barrel body. The syringe barrel has a second barrel open, a second barrel body, a second barrel bottom, and an injection space located in the second barrel body. In this way, the complete-stirred bone cement in the stirring barrel can be directly collected and pushed into the syringe barrel through the movement of the movable plug cover to achieve the effect of completing the preparation of the bone cement quickly and efficiently.

In certain embodiments, the systems, apparatus, and methods disclosed herein relate to robotic surgical systems with built-in navigation capability for patient position tracking and surgical instrument guidance during a surgical procedure, without the need for a separate navigation system. Robotic based navigation of surgical instruments during surgical procedures allows for easy registration and operative volume identification and tracking. The systems, apparatus, and methods herein allow re-registration, model updates, and operative volumes to be performed intra-operatively with minimal disruption to the surgical workflow. In certain embodiments, navigational assistance can be provided to a surgeon by displaying a surgical instrument’s position relative to a patient’s anatomy. Additionally, by revising pre-operatively defined data such as operative volumes, patient-robot orientation relationships, and anatomical models of the patient, a higher degree of precision and lower risk of complications and serious medical error can be achieved.
