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.

In various embodiments, a surgical end effector is disclosed. The surgical end effector comprises a staple cartridge comprising a proximal end and a distal end. The staple cartridge is configured to be used to staple tissue within an optimal tissue thickness range. An anvil is movably coupled relative to the staple cartridge. A tissue thickness sensing module is located adjacent to the distal end of the staple cartridge. The tissue thickness sensing module comprises a sensor and a controller. The sensor is configured to generate a tissue thickness signal indicative of a thickness of the tissue located between the anvil and the staple cartridge. The controller is in signal communication with the sensor. The controller comprises means for identifying a staple cartridge type. The staple cartridge type and the thickness measurement are used to determine if the thickness of the tissue is within the optimal tissue thickness range.

A surgical instrument, such as an endoscopic or laparoscopic instrument. The surgical instrument may comprise an end effector comprising at least one sensor. The surgical instrument may also comprise an electrically conductive shaft having a distal end connected to the end effector wherein the sensor is electrically insulated from the shaft. The surgical instrument may also comprise a handle connected to a proximate end of the shaft. The handle may comprise a control unit electrically coupled to the shaft such that the shaft radiates signals as an antenna from the control unit to the sensor and receives radiated signals from the sensor. Other components electrically coupled to the shaft may also radiate the signals.

Minimally invasive instrument for robotic surgery

Minimally invasive surgery (MIS) challenges the surgeon’s skills due to his separation from the operation area which can only be reached with long instruments. To overcome these drawbacks, minimally invasive robotic surgery (MIRS) plays an important role. This paper describes the development of actuated and sensorized instruments for minimally invasive robotic surgery which help to increase the surgeon’s immersion and dexterity.

Prototype of Instrument for Minimally Invasive Surgery with 6-Axis Force Sensing Capability

Research on surgical robotics demands systems for evaluating scientific approaches. Such systems can be divided into dedicated and versatile systems. Dedicated systems are designed for a single surgical task or technique, whereas versatile systems are designed to be expandable and useful in multiple surgical applications. Versatile systems are often based on industrial robots, though, and because of this, are hardly suitable for close contact with humans. To achieve a high degree of versatility the Miro robotic surgery platform (MRSP) consists of versatile components, dedicated front–ends towards surgery and configurable interfaces for the surgeon. This paper presents MiroSurge, a configuration of the MRSP that allows for bimanual endoscopic telesurgery with force feedback. While the components of the MiroSurge system are shown to fulfil the rigid design requirements for robotic telesurgery with force feedback, the system remains versatile, which is supposed to be a key issue for the further development and optimisation.

DLR MiroSurge: a versatile system for research in endoscopic telesurgery.

In minimally invasive surgery (MIS) the patient's skin forms a spatial barrier between the operation area and the surgeon. This prevents direct access to the operation site which causes a lack of dexterity and limits the sensation of tissue manipulation forces, therefore complicating MIS procedures significantly. A telepresence approach can overcome these limitations: Additional degrees of freedom (DoF) inside the patient provide full manipulability and force torque sensors at the distal end of the instrument allow precise measurement of interaction forces. Using a suitable man-machine interface and free cartesian motion kinaesthetic feedback can be achieved, thus providing a virtual open surgery environment to the surgeon. This article focuses on the development and first results of actuated and sensor integrated instruments as part of the DLR minimally invasive robotic surgery (MIRS) setup. The instruments as a front-end part of the MIRS setup form one base of a telepresence working environment and are crucial for semi-autonomous functions, e.g. motion compensation.

Robotic surgery systems are highly complex and expensive pieces of equipment. Demands for lower cost of care can be met if these systems are employable in a flexible manner for a large variety of procedures. To protect the initial investment the capabilities of a robotic system need to be expandable as new tasks arise.
