An assembly structured to introduce a trocar or other medical instrumentation into a body cavity through an entry site formed in the cavity wall. The introducer assembly includes a base formed of a semi-rigid, flexible and/or a semi-flexible material having an instrument receiving passage extending there through, and further including an exterior sealing surface extending between proximal and distal portions of the base. The sealing surface has a predetermined configuration which is shaped to conform to the shape of the entry site as the base passes into the entry site. A fluid restricting seal is thereby established between the exterior of the base and the peripheral tissue surrounding the entry site, particularly when the entry site is formed by an incision commonly utilized an open laparoscopic procedure.

Laparoscopic instruments and cannulas are provided for performing laparoscopic procedures entirely through the umbilicus. Generally S-shaped laparoscopic instruments placed through the C-shaped trocar sleeves or through the cannula and instrument holder unit provide markedly improved degrees of instruments' freedom during trans-umbilical laparoscopic procedures.

A laparoscopic surgical technique is provided for preparing a site for implantation of a fusion device or implant. In accordance with one embodiment of the technique, a laparoscope is provided having an outer sleeve with distraction fingers at one end to distract the disc space. The laparoscope includes a laparoscopic port at its opposite end through which instruments and implants are inserted. The laparoscope provides a sealed working channel to the disc space, through which the disc space is distracted, the vertebral endplates and surrounding disc is reamed, and the fusion device inserted. The laparoscope is alternately engaged within bilateral locations in the disc space for insertion of a pair of fusion implants. A switching sleeve extends through the laparoscope to protect the tissue at the surgical site as the laparoscope is moved between the bilateral fusion locations.

A surgical clip for a clip applier to ligate vessels. The clip contains two opposing legs connected in parallel by an apex to form a U-shape. Each leg has an outer surface with a half-round cross-sectional configuration for minimizing tissue damage by preventing clip scissoring during ligation. Each leg has an inner surface with a flat central surface, two concave grooves on opposing sides of the central surface, and two convex ridges on opposing sides of the each groove. As a vessel is ligated, vessel tissue moves into the concave grooves while remaining frictionally engaged by the compressive forces applied by the central surfaces and convex ridges of each leg so that the clip does not move on the vessel. The edges of the grooves and the edges of the ridges of each leg are rounded to prevent any cutting of the ligated vessel.

Various surgical instruments for laparoscopic procedures is provided, which are adapted and configured to aspirate and retract a hollow organ, such as a gallbladder. The surgical instruments can includes a needle body, an anchor that is deployable with respect to the needle body, which is adapted and configured for engaging and retracting the hollow organ. Moreover, an aperture can be provided in connection with the needle body, which is adapted and configured for permitting aspiration of contents of the hollow organ. The anchor can be held within, and deployable from, a lumen of the needle body, or held on, and deployable from, an outside surface of the needle body, for example.

This invention provides hermetically-sealed handle assembly with a rotating trigger for use with disposable components, such as surgical clip appliers. The rotating trigger reduces the gripping force necessary to fully control the internal actuator mechanism to operate a disposable surgical clip applier to fully ligate a vessel or other tissue. The hermetic seal on the handle assembly prevents any patient fluids and other bioburden from entering the internal structures. This reduces the possibility of cross-contamination and the costs of sterilization.

Surgical techniques and instruments are provided for performing surgical procedures in a disc space. The instrument includes a sleeve having a distal end and an opposite proximal end and a working channel extending therebetween. The working channel includes a first portion and an adjacent second portion configured to receive surgical instruments therethrough. A cap member is secured to the sleeve at the proximal end. The cap member has a sealable access port substantially aligned with a corresponding one of the first or second portions. The cap member is movable with respect to the sleeve to substantially align the access port with the other of the first and second portions while the working channel remains sealed. Various techniques using various surgical instruments in laparoscopic procedures are also disclosed.

Disclosed is a minimally invasive surgical instrument that may be used in hand-assisted laparoscopic surgeries. The device is a multifunctional surgical instrument that may be mounted directly on a surgeon's fingertip and inserted through an incision to allow the surgeon to manipulate tissue during a surgical procedure. Versions include marking elements that are actuated to expose marking flowable fluid (e.g., ink pad, marker tip, roller ball). Versions include those that actuate to open an ampoule containing a flowable material (e.g., adhesive) with continued actuation causing dispensing. In addition, two compounds that are mixed at the time of application are provided with a bifurcated ampoule version and a dual cylinder/plunger version.

An apparatus, method and system for the deployment of surgical mesh material, which are particularly suited for the use in the laparoscopic surgical repair of hernias. An inner actuator rod slides within a main shaft. Mesh deployment arms are connected to an end of the shaft, and a surgical mesh is mounted to and rolled around the deployment arms. An outer housing slides over the main shaft, the deployment arms, and conformed mesh. By sliding the main shaft in a first direction, the mesh is exposed and the actuator rod is retracted, which actively flexes the deployment arms, thereby unfurling the mesh. By sliding the main shaft in an opposite direction, the to tension on the deployment arms is relaxed, and the deployment arms disengage from the actuator rod allowing the deployment apparatus to be withdrawn from the mesh.

A laparoscopic device assembly provides a tubular diaphragm twist seal that responds to a slight rotation of an actuating ring in a first direction by coupling a motor spring power assisted rotation of a bottom circumference of the twist seal achieves a pneumatic seal in an adjustable access channel defined by the state of the twist seal for maintaining an insufflated body cavity for a hand assisted laparoscopic surgical procedure. A slight rotation of the actuating ring in an opposite second direction releases compression spring energy and energy in the twisted state of the twist seal so that an upper circumference of the twist seal is allowed to open the adjustable access channel.
