The present invention relates to a device for navigating a medical instrument relative to a patient anatomy, a method for navigating a medical instrument relative to a patient anatomy, and a program element which, when executed by a computer, executes this method. The device comprises a position determination unit, a computing unit and a navigation display. The position determination unit comprises a sensor module configured to acquire current 3D data of the patient anatomy. The position determination unit further comprises a position sensor which is configured to acquire current movement data of the medical instrument. The computing unit is configured to match the current 3D data of the patient anatomy and the current movement data of the medical instrument with preoperative image data of the patient anatomy and, on this basis, to calculate navigation information for the medical instrument. The navigation display is configured to show the calculated navigation information.

An apparatus for use in placing an implant into a patient is disclosed. The apparatus features an outer assembly having an outer shaft with an expandable driving member at its distal end and an inner canulated shaft that fits within and cooperates with the outer shaft to affect the driving member. The inner shaft includes an actuation knob attached to the proximal end of the inner shaft. A locking or driving thread is included on the outer surface of the inner shaft, proximal to the adjustment knob. The outer shaft includes a housing with the threaded interior such that when the inner shaft is mounted within the outer shaft, the driving thread operates with the threaded interior of the housing to allow for the inner shaft to be advanced along the inside of the outer shaft as the knob is turned. The tip of the inner shaft interacts with the interior of the driving member to expand the driving member.

A surgical navigation system includes a first tracking unit, a second tracking unit and a processing unit. The first tracking unit captures a first infrared image of a position identification unit that includes a reference target fixed on a patient and an instrument target disposed on a surgical instrument. The second tracking unit captures a second infrared image of the position identification unit. The processing unit performs image recognition on the first and second infrared images with respect to the position identification unit, and uses, based on a result of the image recognition, a pathological image and one of the first and second infrared images to generate an augmented reality image. When both the first and second images have both the reference target and the instrument target, one of the first image and the second image with a higher accuracy is used to generate the augmented reality image.

An alignment device includes an elongate rod, a sealing hub coupled to a proximal end of the elongate rod and configured to form a fluid-tight seal within a portion of a percutaneous-access device, and an alignment structure coupled to the sealing hub and having a form configured to engage with a component of an instrument manipulator assembly of a robotic system.

An adapter apparatus for a cable saw or similar cutting implement includes a hub adapter that may detachably engage a mounting hub of a power tool. A pair of lateral arms extend outward on opposing sides of the hub adapter to a connection interface of the cable saw. The connection interface engages opposing wire ends of the cable saw and provides for a cutting operation in response to an oscillating motion of the power tool.

A surgical device includes an adapter assembly that selectively interconnects a loading unit and a device housing. The adapter assembly includes a drive converter assembly for interconnecting a rotatable drive shaft and an axially translatable drive member of the loading unit. The drive converter assembly converts and transmits a rotation of the rotatable drive shaft to an axial translation of the axially translatable drive member of the loading unit. The drive converter assembly includes a drive element, a drive nut, and a distal drive member. The drive element defines a longitudinal axis. The drive nut is disposed about the longitudinal axis, and the distal drive member is disposed along the longitudinal axis.

A surgical stapling device includes an elongate body, a tool assembly pivotably coupled to the elongate body for articulation, and a drive assembly. The drive assembly is movable in relation to the tool assembly to eject staples from the tool assembly and cut tissue clamped between jaws of the tool assembly. The drive assembly includes a working end that is coupled to a flexible drive beam. The flexible drive beam includes a metallic core member and outer laminates secured to opposite sides of the core member. The outer laminates are formed of a material having a lower coefficient of friction than the core member to minimize firing forces of the surgical stapling device.

A face mask (90) comprises an instrument shielding apparatus (91) which comprises an instrument shielding device (92) which is connected to the face mask (90) by an adapter (89). The adapter (89) comprises an instrument accommodating housing (15) through which an instrument bore (25) extends therethrough. The instrument accommodating housing (15) terminates at one end in a first main port (20) engageable with an instrument port (7) of the face mask (90), and in the other end in a second main port (23). The instrument shielding device (92) comprises a shielding sleeve (95) a first end (96) of which is secured by a coupling ring (98) to the second main port (23) of the adapter (89), and a second end (97) of which is secured in a storage chamber (94) of a sleeve storing housing (93) of the instrument shielding device (92). The sleeve storing housing (93) is sealably engageable with a proximal end (58) of an endoscope (10), and the shielding sleeve extends from a collapsed stored state in the storage chamber (94) to the adapter (89) for shielding the endoscope (10).

A reusable surgical device includes a housing or body that supports one or more thermal energy storage members that retain or store heat during a cleaning and sterilization process. The stored heat functions to evaporate water that remains within the body or housing of the surgical device after the cleaning and sterilization process is completed to minimize any likelihood of infection of a patient or damage to electronics within the surgical device that may result or occur due to the presence of the water within the surgical device.

Disclosed herein are rasp adapters, rasp systems, and method of use thereof. The rasp adapter can include a body and a retention element. The body can define a body cavity, a handle opening, and a trunnion bore. The retention element can be located within the body cavity and can include a knuckle and a heal. The knuckle can be located proximate to and movable into and out of the trunnion bore. The heal can be located proximate the handle opening. Movement of the retention element due to a force applied to the heal can cause movement of the retention element and movement of the knuckle into the trunnion bore.
