A surgical instrument access port assembly and method of use, the surgical instrument access port a surgical instrument has a needle lumen and a surgical access port. The needle lumen extends in a longitudinal direction and includes a needle tip at a distal end, and a body portion at a proximal end, the body portion having at least one recess or finger. The surgical access port has a cannula defining a hollow cannula shaft, and a tapered hub attached to a proximal end of the cannula. The tapered hub includes at least one inner ring configured to abut against the at least one recess or finger while the surgical instrument is inserted into the cannula of the surgical access port.

Exchanger surgical access port and methods of use

A surgical device may include a disposable needle assembly, a reusable handle assembly, and a retractable slide. The handle assembly may include a ratchet mechanism, a locking mechanism, an arming mechanism, and a cage. A method for inserting and releasing the disposable needle assembly from the reusable handle assembly is also disclosed herein.

Needlescopic instrument with reusable handle and detachable needle assembly

A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter of 3.0 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow needle. The coaxial surgical instrument includes end effectors at the end of the shaft which are biased to an open position such that when the end effectors of the surgical instrument extended out of the needle they open, and they are closed by relative movement of the needle over them. The assembly preferably includes a first fixing element which is used to fix the relative location of the surgical instrument and the needle. The assembly also preferably includes a second fixing element which moves relative to the needle and is located on the outside thereof and which is used to fix the relative location of the needle to the patient.

Minimally invasive surgical assembly and methods

A surgical access port assembly including a cannula having a diameter of less than about 3 mm and a tapered hub, capable of attachment to a laparoscopic surgical instrument, connected to the proximal end of the cannula.

Exchanger surgical access port assembly and methods of use

A needlescopic scissors end effector assembly includes a pair of jaws or blades pivotable to perform a cutting or shearing operation. The scissors end effector assembly includes a cannula having a diameter between about 1 mm to 5 mm and a needle tip configured for percutaneous operation. The pair of jaws or blades includes cam profile surfaces to interact with an opening defined with the needle tip to actuate opening and closing of the pair of jaws or blades and to prevent backlash effect during the opening and closing of the pair of jaws or blades.

Needlescopic scissor end effector and methods of use

A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter, a longitudinal axis, and a sharp distal end. An insulating member extends through the hollow needle and is movable relative to the hollow needle. An elongated member extends through the insulating member and is movable relative to both the insulating member and the hollow needle. A resilient wire projects from the elongated member and is retractable within and extendable outside of the insulating member and the hollow needle. The insulating member, elongated member, and resilient wire are movable relative to the needle using first and second moving means whereby the surgical assembly assumes various configurations having different operational functions.

Minimally invasive surgical needle and cauterizing assembly and methods

A surgical device including a disposable needle assembly, a reusable handle assembly and a retractable slide. A method for inserting and releasing a disposable needle assembly from a reusable handle assembly is included. The handle assembly includes a ratchet mechanism, locking mechanism, arming mechanism and a cage.

A surgical device includes an elongated needle body defining an interior lumen extending longitudinally therethrough, having a sharpened distal tip portion. The device further includes an assembly operatively associated with the interior lumen of the needle body. The assembly includes a shaft having an outer surface profile corresponding to an inner surface of the interior lumen of the needle body and a pair of arms extending distally from the shaft. The pair of arms are biased radially outward from the longitudinal axis of the shaft, and each of the pair of arms having a blunt front surface, wherein one of the arms is in a fixed axial alignment with the sharpened distal tip portion of the needle body such that the arms act as an obturator relative to the sharpened distal tip portion of the needle body to guard the needle body from causing accidental needle tip trauma.
