A surgical system including a surgical instrument and a protection device is included. The surgical system includes a surgical instrument having an extension assembly releasably coupled thereto. The extension assembly includes a trocar member disposed within a distal end of the extension assembly and the trocar member includes an engagement feature defined in an outer surface thereof. The protection device is releasably coupled to the engagement feature of the trocar member, thereby providing a barrier adjacent a tip of the trocar member. A method of sterilizing a surgical instrument is also provided.

Covidien | Date: 2017-04-05

An implant for use as a hemostat comprising: a porous fibrous substrate having pores over at least a portion thereof; a first hydrogel precursor applied to a first portion of the porous substrate; and a second hydrogel precursor applied to a second portion of the porous substrate, the first portion of the porous substrate being spatially separated from the second portion of the porous substrate.


A surgical loading unit for use with a handle assembly includes an elongate outer frame, an end effector mounted to a distal end of the outer frame, a drive at least partially disposed within the outer frame and operatively coupled to the end effector, and being adapted for longitudinal movement through a plurality of sequential firing strokes to operate the end effector, and a rotatable counter mounted to the outer frame and adapted for rotational movement about the longitudinal axis. The rotatable counter has visual indicators for providing visual indicia corresponding to a number of firing strokes completed by the drive. A counter actuator is mounted to the drive and dimensioned to engage the rotatable counter to cause rotational movement of the rotatable counter through an arc segment of rotation during each firing stroke of the drive. A cam actuator is mounted to the drive and dimensioned to operatively engage the counter actuator to cause release of the counter actuator from the rotatable counter upon longitudinal movement of the drive through each successive return stroke.

The present disclosure is directed to an augmented surgical reality environment system and methods. The system includes an image capture device to capture an image of a surgical environment. At least one biometric sensor obtains biometric data from a patient. A controller includes a memory configured to store a plurality of anatomical images and a processor. The processor receives at least one of the captured image, the biometric data, or one or more anatomical images from the plurality of anatomical images and generates an augmented image from at least one of the captured image, the biometric data, or the one or more anatomical images. A display device displays the augmented image.


Patent
Covidien | Date: 2017-03-15

An electrosurgical pencil, comprising: a housing; an electrocautery blade having a proximal portion configured to removably couple to the housing, the electrocautery blade configured to electrically connect to an electrosurgical generator; a hub coupled to a distal portion of the housing and defining a lumen configured to receive at least a portion of the electrocautery blade therein; and a sheath coupled to the hub and defining a lumen configured to receive at least a portion of the electrocautery blade therein, the hub configured to rotate relative to the housing to move the sheath between a first position to cover the electrocautery blade and a second position to expose a distal portion of the electrocautery blade.


Patent
Covidien | Date: 2017-01-25

An anvil assembly suitable for trans-oral delivery includes an anvil head configured to receive a guide suture that is separable from the anvil assembly during a stapling procedure. An anvil delivery assembly includes the anvil assembly and a suture guide assembly secured to the anvil assembly.


Patent
Covidien | Date: 2017-02-08

A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.
