An apparatus for attaching a cannula to a robotic surgical system, the apparatus comprising: a clamp assembly configured to attach a cannula to a robotic surgical system, the clamp assembly comprising an actuator coupled to a clamp to transition the clamp between an open position configured to receive the cannula and a closed position to attach the cannula to the robotic surgical system; and a lock out assembly coupled to the clamp assembly to control the transition of the clamp, the lock out assembly having a hook that is dimensioned to engage a bearing coupled to the actuator when the clamp is in the open position and disengage the bearing to allow the clamp to automatically transition to the closed position.

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.

Some embodiments of a medical device anchor system include an anchor sleeve that receives a catheter (or other medical instrument) though a working channel of the anchor sleeve. The anchor sleeve may include a first actuator that controls the extension of one or more subcutaneous tines into the subcutaneous region under the skin. The anchor sleeve can also include a second actuator that can cause the anchor sleeve to lock onto an outer portion of the catheter (or other medical instrument) arrange in the working channel.

The various inventions relate to robotic surgical devices, consoles for operating such surgical devices, operating theaters in which the various devices can be used, insertion systems for inserting and using the surgical devices, and related methods.

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.

A medical device assembly may include a stylet having a distal stylet body and a proximal stylet hub, a cannula having a distal cannula body and a proximal cannula hub, and a lock for securing the stylet to the cannula, wherein the lock includes at least one abutment on at least one of the stylet hub and the cannula hub for restricting relative movement between the stylet hub and the cannula hub.

An aiming arm system comprises an aiming arm and a guide sleeve. The aiming arm has 1) a body and a guide hole that extends through the body along a hole axis, and 2) a retention element supported relative to the body. The aiming arm is configured to be positioned such that the hole axis is aligned with a target location of an anatomical implant. The guide sleeve extends along a linear direction, and is sized to be inserted through the guide hole in the linear direction. Relative rotation between the guide sleeve and the retention element transitions the aiming arm system between an unlocked configuration whereby the guide sleeve is insertable through the guide hole, and a locked configuration whereby the retention element applies a retention force to the guide sleeve that substantially prevents the guide sleeve from moving further along the linear direction.

A puncture needle includes: an outer needle including a lumen extending in an axial direction; an outer needle hub joined to a proximal end portion of the outer needle; an inner needle located in the lumen of the outer needle; a switching mechanism configured to switch between a first state in which a needle tip of the puncture needle is sharp and a second state in which the needle tip of the puncture needle is blunt by displacing the inner needle in the axial direction; and a lock mechanism that maintains a position of the inner needle.

A medical instrument includes a handle, a trocar in communication with the handle, and a cannula in communication with the trocar and the handle. The cannula is engaged (locked) with the handle when linearly displaced proximally towards the handle and, the cannula is disengaged (unlocked) from the handle when linearly displaced distally away from the handle. The cannula is linearly reciprocated, between the locked position and the unlocked position, along a linear travel path defined parallel to a longitudinal axis of the trocar such that the cannula is prohibited and permitted to articulate about the longitudinal axis of the trocar, and relative to the handle, respectively. Advantageously, the cannula is locked and unlocked from the trocar by without requiring an external force exerted generally transverse to trocar and/or cannula, thereby permitting a user to lock/unlock the cannula, relative to the trocar, with one hand.

Surgical access port stabilization systems and methods are described herein. Such systems and methods can be employed to provide ipsilateral stabilization of a surgical access port, e.g., during spinal surgeries. In one embodiment, a surgical system can include an access port configured for percutaneous insertion into a patient to define a channel to a surgical site and an anchor configured for insertion into the patient's bone. Further, the access port can be coupled to the anchor such that a longitudinal axis of the access port and a longitudinal axis of the anchor are non-coaxial. With such a system, a surgeon or other user can access a surgical site through the access port without the need for external or other stabilization of the access port, but can instead position the access port relative to an anchor already placed in the patient's body.
