Surgical stapling instrument having load sensing control circuitry

A surgical instrument for being endoscopically or laparoscopically inserted into a surgical site for simultaneous stapling and severing of tissue includes load sensing pressure transducers strategically placed for closed loop control and monitoring. Load sensing within a staple applying assembly (end effector) may provide feedback for preventing firing with insufficient or too much tissue, or to sense appropriate presence buttress material, to deploy buttress material after firing is sensed.

Apparatus and method for performing a bypass procedure in a digestive system

Surgical instrumentation and methods for performing a bypass procedure in a digestive system incorporate laparoscopic techniques to minimize surgical trauma to the patient. The instrumentation includes an outer guide member dimensioned for insertion and passage through an esophagus of a patient and defining an opening therein extending at least along a portion of the length of the outer guide member, an elongate anvil delivery member at least partially disposed within the opening of the outer guide member and being adapted for longitudinal movement within the outer guide member between an initial position and an actuated position and an anvil operatively engageable with the delivery member. The anvil includes an anvil rod defining a longitudinal axis and an anvil head connected to the anvil rod. The anvil head is at least partially disposed within the opening of the outer guide member when in the initial position of the delivery member and is fully exposed from the distal end of the outer guide member upon movement of the delivery member to the actuated position.

Disposable loading units for a surgical cutting and stapling instrument

In various embodiments, a disposable loading unit for a surgical stapling instrument can include an anvil, a staple cartridge, a staple cartridge channel for operably supporting the staple cartridge, and a connector for removably attaching the disposable loading unit to the surgical instrument. In at least one embodiment, a first staple cartridge can be replaced with another staple cartridge after the first staple cartridge has been at least partially expended. In various embodiments, a staple cartridge can include a staple driver for deploying staples from the staple cartridge and a cutting member for incising tissue, wherein a new staple driver and a new cutting member can be provided with each new staple cartridge. The anvil can be removably attachable to the disposable loading unit such that a new anvil can be utilized with a new staple cartridge.

Electrosurgical instrument and method of use

InactiveUS7112201B2Reduce conductancePrevent any substantial dehydrationSurgical instruments for heatingCoatingsMicron scaleElastomer
An electrosurgical medical device and method for creating thermal welds in engaged tissue. In one embodiment, at least one jaw of the instrument defines a tissue engagement plane carrying a conductive-resistive matrix of a conductively-doped non-conductive elastomer. The engagement surface portions thus can be described as a positive temperature coefficient material that has a unique selected decreased electrical conductance at each selected increased temperature thereof over a targeted treatment range. The conductive-resistive matrix can be engineered to bracket a targeted thermal treatment range, for example about 60° C. to 80° C., at which tissue welding can be accomplished. In one mode of operation, the engagement plane will automatically modulate and spatially localize ohmic heating within the engaged tissue from Rf energy application—across micron-scale portions of the engagement surface. In another mode of operation, a conductive-resistive matrix can induce a “wave” of Rf energy density to sweep across the tissue to thereby weld tissue.

Surgical instruments

A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can further include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can be set such that the sheath can act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath in order to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.

Articulated surgical instrument for performing minimally invasive surgery with enhanced dexterity and sensitivity

An articulated surgical instrument for enhancing the performance of minimally invasive surgical procedures. The instrument has a high degree of dexterity, low friction, low inertia and good force reflection. A unique cable and pulley drive system operates to reduce friction and enhance force reflection. A unique wrist mechanism operates to enhance surgical dexterity compared to standard laparoscopic instruments. The system is optimized to reduce the number of actuators required and thus produce a fully functional articulated surgical instrument of minimum size.

Minimally invasive apparatus for implanting a sacral stimulation lead

Methods and apparatus for implanting a stimulation lead in a patient's sacrum to deliver neurostimulation therapy that can reduce patient surgical complications, reduce patient recovery time, and reduce healthcare costs. A surgical instrumentation kit for minimally invasive implantation of a sacral stimulation lead through a foramen of the sacrum in a patient to electrically stimulate a sacral nerve comprises a needle and a dilator and optionally includes a guide wire. The needle is adapted to be inserted posterior to the sacrum through an entry point and guided into a foramen along an insertion path to a desired location. In one variation, a guide wire is inserted through a needle lumen, and the needle is withdrawn. The insertion path is dilated with a dilator inserted over the needle or over the guide wire to a diameter sufficient for inserting a stimulation lead, and the needle or guide wire is removed from the insertion path. The dilator optionally includes a dilator body and a dilator sheath fitted over the dilator body. The stimulation lead is inserted to the desired location through the dilator body lumen or the dilator sheath lumen after removal of the dilator body, and the dilator sheath or body is removed from the insertion path. If the clinician desires to separately anchor the stimulation lead, an incision is created through the entry point from an epidermis to a fascia layer, and the stimulation lead is anchored to the fascia layer. The stimulation lead can be connected to the neurostimulator to delivery therapies to treat pelvic floor disorders such as urinary control disorders, fecal control disorders, sexual dysfunction, and pelvic pain.

Conical laparoscopic apparatus for minimally invasive surgery

A single body port or body flange access device having an oval shape and associated stabilizer anchor for performing laparoscopic surgery is disclosed. The device is slipped into the body anchor stabilizer first so that the anchor stabilizer lifts up fat and peritoneum inside the body thereby keeping the operating area clear and acting to hold the body flange in place. The device further has a plurality of crisscrossing conduits assuming the shape of a cone through which surgical instruments may be inserted. The instruments are manipulated so that triangulation is obtained using one patient body flange while standard surgical procedures are performed on the patient. Due the oval shape of the device, the device minimally rotates while instruments are manipulated.
