An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

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.

Surgical access stabilization devices, systems, and methods are disclosed herein. For example, the devices, systems, and methods disclosed herein can be used during a surgical procedure to selectively establish, stabilize, and maintain a desired trajectory and/or positioning of a surgical access device. An exemplary surgical access stabilization device can include a pad with an adhesive distal facing surface to adhere to an anchor surface, a surgical access device coupled to the pad, and a locking mechanism to selectively lock a position of the surgical access device relative to the pad. In one embodiment, the anchor surface can be the skin of a patient. An exemplary surgical access device stabilization method can include making an incision in a patient at a surgical site, inserting a surgical access device through the incision, adhering a pad to an anchor surface, e.g., the skin of the patient, coupling the surgical access device to the pad, and selectively locking a position of the surgical access device relative to the pad. Other exemplary devices, systems, and methods are also provided.

A flexible puncture needle device includes a puncture needle (10). The puncture needle (10) includes an outer tube (11) and a central tube (13). The outer tube (11) includes a puncture needle head (111) and a plurality of segments (112). The puncture needle head (111) includes a needle tip at front end and a pair of notches (1122) or a pair of protrusions (1121) at rear end, and a pair of protrusions (1121) and a pair of notches (1122) are formed at two ends of the segment (112), respectively. A pair of protrusions (1121) or a pair of notches (1122) at an end of the segment (112) are engaged with a pair of notches (1122) or a pair of protrusions (1121) at rear end of the puncture needle head (111) to form a needle head joint. Two adjacent segments (112) are engaged via the notches (1122) and the protrusions (1121) to form a joint, and the needle head joint and a plurality of joints are sequentially engaged with each other from head to tail to form an outer tube (11) with the puncture needle head (111) at tip end and a tube body capable of axially bending. Central tube (13) is inserted into the outer tube (11) from another end of the outer tube (11) away from the puncture needle head (111) to form a central tube vacant portion (114) and central tube insertion portion (115) of the outer tube (11). The central tube vacant portion (114) is capable of bending, and during the forward or backward movement of the central tube (13) in the outer tube (11) along an axis of the outer tube (11). A bendable angle of the central tube vacant portion (114) changes as a length of the central tube vacant portion (114) changes.

A surgical access device assembly includes a cannula hub and a cannula tube. The cannula tube extends distally from the cannula hub along a longitudinal axis. The cannula tube defines a working channel. The cannula tube includes a tissue engagement feature and a balancing feature. The balancing feature is configured to promote lateral stability of the cannula tube and the cannula hub relative to the body cavity wall of the patient. The balancing feature includes a proximal portion of the cannula tube having a first wall thickness. The balancing feature also includes a distal portion of the cannula tube having a second wall thickness that is greater than the first wall thickness. At least a portion of the proximal portion is proximal relative to the tissue engagement feature. At least a portion of the distal portion is distal relative to the tissue engagement feature.

A gyroscopic stabilizer configured to stabilize a surgical instrument relative to a patient includes a frame having a central axis and a hub configured to releasably couple with the surgical instrument. A first gyroscope assembly is coupled with a first frame portion and a second gyroscope assembly is coupled with a second frame portion. Each gyroscope assembly includes a gimbal pivotably coupled with the respective frame portion about a precession axis, a motor, and a rotor rotatably coupled with the motor about a spin axis perpendicular to the respective precession axis. Each gyroscope assembly is operable generate a torque in a torque plane that contains the respective spin axis and the respective precession axis. The torques are configured to resist rotation of the gyroscopic stabilizer relative to the patient about respective device axes that are perpendicular to the central axis and to one another.

A method and device for placing and/or retaining medical devices on an animal or subject is provided that may include an anchoring device having a body with a channel or aperture through which a medical device may pass and be reversibly retained at given degrees of insertion, a retaining mechanism for controlling the release or retention of the medical device in the channel or aperture, and an attachment feature for attaching the anchoring device to an animal or subject (e.g. onto the skin of a human). The anchoring device may be attached to a subject, such as over the site of an incision or other point of access to the interior of the subject, and a medical device may be inserted into the interior via the channel or aperture in the body of the anchoring device and retained by action of the retention mechanism.

An integrated sheath assembly for inserting a medical device such as a percutaneous pump into a vessel can include a first sheath having a first lumen defining a first opening between proximal and distal ends of the first sheath for passage of a portion of the pump and a second sheath having a second lumen defining a second opening between proximal and distal ends of the second sheath. The second lumen is expandable to allow passage of the first sheath containing the portion of the pump. The first sheath fills a space between the second sheath and the portion of the percutaneous pump when the first sheath containing the percutaneous pump is inserted into the second lumen. The first sheath has a first hub, and the second sheath has a second hub. In some embodiments, a single sheath and a movable connector can be integrated on the medical device.

Adjustable-length surgical access devices are disclosed herein, which can advantageously allow an overall length of the access device to be quickly and easily changed by the user. The access devices herein can reduce or eliminate the need to maintain an inventory of many different length access devices. In some embodiments, the length of the access device can be adjusted while the access device is inserted into the patient. This can reduce or eliminate the need to swap in and out several different access devices before arriving at an optimal length access device. This can also reduce or eliminate the need to change the access device that is inserted into a patient as the depth at which a surgical step is performed changes over the course of a procedure. Rather, the length of the access device can be adjusted in situ and on-the-fly as needed or desired to accommodate different surgical depths.
