A surgical retractor is disclosed herein. In some embodiments, a surgical retractor includes a body extending from a proximal end to a distal end and having a first portion coupled to a second portion via a hinged connection, wherein the first and second portions are configured to rotate about a body axis; a first radiolucent tip coupled to a distal portion of the first portion; a second radiolucent tip coupled to a distal portion of the second portion; a holder coupled to one of the first or second portions; and a deformable member extending through the holder, wherein the deformable member is configured to be deformed to facilitate fixation of the surgical retractor at a desired location.

Apparatus for securing a first bone fragment to a second bone fragment, said apparatus comprising: a fusion device, said fusion device comprising: a shaft having a first end and a second end; a first bone-engaging feature formed on said shaft at a first location, said first bone-engaging feature comprising at least one barb which, in its unbiased condition, flares outwardly from the longitudinal axis of said shaft and which is capable of being elastically constrained to a position substantially parallel to the longitudinal axis of said shaft, such that said first end of said shaft may be advanced into a hole in the first bone fragment when said at least one barb is elastically constrained to a position substantially parallel to the longitudinal axis of said shaft but is prevented from being withdrawn from the hole in the first bone fragment when said at least one barb is in its unbiased condition; and a second bone-engaging feature formed on said shaft at a second location, said second bone-engaging feature comprising at least one barb which, in its unbiased condition, flares outwardly from the longitudinal axis of said shaft and which is capable of being elastically constrained to a position substantially parallel to the longitudinal axis of said shaft, such that said second end of said shaft may be advanced into a hole in the second bone fragment when said at least one barb is elastically constrained to a position substantially parallel to the longitudinal axis of said shaft, but is prevented from being withdrawn from the hole in the second bone fragment when said at least one barb is in its unbiased condition.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

The invention relates to a recalibration device (1) used during the acquisition of images of an anatomical area of a patient during robot-assisted surgery, including a body (3) made of radxoliacent material, which comprises fiducial markers (9) made of radiopaque material, said body (3) having a bearing surface (7) intended to be manually placed on a surface of said anatomical area of the patient. According to the invention, said fiducial markers (9) are arranged in a specific geometrical pattern enabling a certain detection of the positioning and orientation of the recalibration device (1) in a three-dimensional digital model built from the images derived from the acquisition of the anatomical area.

An assembly for fastening tissue is disclosed. The assembly may comprise a first jaw comprising a cartridge, wherein the cartridge comprises a plurality of fasteners. The plurality of fasteners comprises a first fastener comprising a first height and a second fastener comprising a second height, wherein the second height is different than the first height. The assembly further comprises a second jaw, wherein at least one of the first jaw and the second jaw is movable relative to the other. The second jaw comprises a plurality of fastener-engaging portions. The plurality of fastener-engaging portions comprises a first fastener-engaging portion and a second fastener-engaging portion. The assembly further comprises a compressible layer intermediate the first jaw and the second jaw.

A surgical instrument includes a gripping assembly, a shaft assembly, an end effector, and a pivoting member. The gripping assembly defines a first opening for receiving a finger or a thumb of a user. The gripping assembly includes a first deformable feature that is configured to be moved in order to increase or decrease a cross-sectional area of the first opening. The shaft assembly extends distally from the gripping assembly. The end effector is positioned at a distal end of the shaft assembly and includes a first member. The pivoting member is pivotably coupled with the shaft assembly. The pivoting member is pivotable with respect to the first member of the end effector between an open position and a closed position to thereby clamp tissue between the first member and the pivoting member.

A retractor having a housing having a handle portion at a first end and a blade portion at a second, opposite end. The retractor includes a light system having an organic light source for illuminating the blade portion. The light system is positioned within the housing such that it is fully encased by said housing. A pair of polarized light panels are attached to the blade portion for varying direction of light from the blade portion.

This disclosure is directed to surgical fixation devices (e.g., staples, screws, etc.) which are able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The surgical fixations devices are manufactured from a shape memory material (e.g., a material capable of exhibiting superelasticity and/or a temperature-induced shape change).

An improved implant inserter, and method of using same, with an elongated, substantially rigid shaft having a proximal surface which is capable of receiving a driving force, and a substantially rigid tip portion having a distal end and a proximal end. At least the distal end of the tip portion is capable of being placed within an implant such as a suture anchor. The inserter further includes a compliant region disposed between the tip portion and the shaft which requires less lateral force to bend than the tip portion, at least when the tip portion has been placed within the implant.

The present disclosure relates to methods and devices for surgically manipulating tissue. In general, the methods and devices can include an elongate retractor shaft having a distal retractor tip that is configured to manipulate tissue, for example the tip can be configured to separate muscle and nerve fibers surrounding a vertebra. The elongate retractor shaft can include an illumination source such that at least a portion of the surgical field is illuminated by the device when the device is used in the body. A sensor can also or alternatively be included on the elongate retractor shaft, for example on the blunt retraction tip, such that the sensor can monitor physiological parameters of the tissue in or adjacent to the surgical field.
