A self-contained powered surgical stapling apparatus is provided which includes an elongate body, a fastener applying assembly including an anvil for forming a surgical fastener driven thereagainst, a motor assembly and power source for energizing the motor assembly disposed within the elongate body, and a pusher driven by the motor assembly for driving a surgical fastener toward the anvil to be formed thereby and fastened to body tissue. The apparatus is configured for utilization during conventional invasive surgical procedures as well as endoscopic or laparoscopic surgical procedures by providing a detachable extension shaft.

A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Surgical stapling instrument with an articulatable end effector

A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

A surgical instrument including a handle assembly, a first endoscopic portion, a motor, and a first end effector is disclosed. The first endoscopic portion is selectively connectable to a distal portion of the handle assembly and defines a longitudinal axis. The first endoscopic portion includes a housing adjacent its proximal portion and includes an actuation member. The motor is disposed in mechanical cooperation with the housing of the first endoscopic portion and is operatively connected to the actuation member for moving the actuation member substantially along the longitudinal axis. The first end effector is selectively connectable to a distal portion of the first endoscopic portion and is configured to perform a first stapling function.

The device comprises a rotationally driven surgical instrument incorporating a hand-held element having a mount rotatably installed therein for reception of interchangeable cutting and milling inserts, a driving motor for driving the mount receiving the tool inserts, a control unit for controlling the driving motor with means of setting the rotational speed and of preselecting the rotational speed range and direction of rotation as well as a digital indicator for displaying the rotational speed set up in each case. For the purpose of accessible storage of setting data, the control unit incorporates a non-volatile read-write memory for digital storage of rotational speeds, a code carrier as well as a coding/decoding arrangement.

In an apparatus for the insufflation of gas into a body cavity the dynamic pressure of the gas flow conducted to the body cavity and the static intra-abdominal pressure in the body cavity are detected with at least one measuring transducer. The electrical output signal of the measuring transducer detecting the pressure is converted by difference formation with a compensation signal, which substantially takes into account the resistance to flow of the instrument conducting the gas into the body cavity, into a difference signal corresponding to the static intra-abdominal pressure. With this signal a control circuit for the setting of the desired pressure value in the body cavity is controlled, in which respect the compensation signal in each case at the start of the insufflation is generated from the output signal of the relevant measuring transducer and is stored in a store and upon gas flow the stored compensation signal is fed to the one input and the output signal of the measuring transducer is fed to the other input of an operational amplifier for the formation of the difference signal, whilst the store at the input store is separated electrically from the measuring transducer by way of a switch.

Equipment is disclosed for the controlled insufflation of a fluid into a body cavity through a probe inserted thereinto, particularly for insufflating gas through the conduit of an endoscope partly inserted into the body cavity The equipment comprises a supply device for delivering the fluid and on which a selected nominal value for the pressure in the body cavity can be set and the relevant actual value of the body cavity pressure can be displayed by means of a measuring instrument The inlet side of a circulating pump, is connected by way of a filter to the body caviy During an operation the pump draws off fluid from the body cavity and circulates it back to the body cavity Part of the circuit on the delivery side of the pump and part of the circuit leading to the measuring instrument have a common portion leading to the body cavity When the pump is running, therefore, a retroactive dynamic pressure is applied to the measuring instrument The dynamic pressure is compensated for by a partial vacuum derived from the delivery flow of the pump

Equipment for the controlled insufflation of a fluid into a body cavity

An apparatus is disclosed for measuring the throughflow of a body liquid, in particular an apparatus for measuring the flow of urine in urological function diagnostics. The apparatus comprises a collecting funnel connected to a tube, which can be suspended in a WC bowl. In the tube are two axially spaced transducers one for continuously determining the electrical conductivity of fluid flowing through the tube from the funnel and the other for determining the specific electrical conductivity of the liquid. An electronic evaluation system determines the throughflow of the liquid upon the basis of the values determined by the transducers.
