The present invention provides a chest tube introducer which can be inserted without a need of surgical procedures. The chest tube introducer comprises a series of compartmentalized leakproof sealing devices, which is configured for safe introduction of the chest tube introducer minimizing a risk of pneumothorax.

A method of using a surgical modular robotic assembly including an interchangeable motor pack, a hand-held surgical instrument, and a robotic surgical instrument is disclosed. The method includes releasably attaching an interface portion of the interchangeable motor pack to the hand-held surgical instrument, causing the interchangeable motor pack to drive a first surgical tool of the hand-held surgical instrument, stopping the interchangeable motor pack from driving the first surgical tool, disconnecting the interface portion from the hand-held surgical instrument, and releasably attaching the interface portion of the interchangeable motor pack to the robotic surgical instrument.

Meniscal repair devices, systems, and methods are provided.

A percutaneous access device for use in minimally invasive surgery includes an elongated body having a proximal portion and an opposing distal portion. The proximal portion has a proximal bore extending therethrough and the distal portion has a distal bore extending therethrough. The distal portion of the body is hingedly connected to the proximal portion in a first percutaneous access position and a second anchoring position. In the first percutaneous access position the distal and proximal bores are linearly aligned when a surgical instrument is inserted into both the proximal and distal bores. In the second anchoring position the distal bore is angularly displaced from the proximal bore when the surgical instrument is removed from the distal bore.

Surface features for device retention are disclosed herein, e.g., for retaining an access port within a patient during a surgical procedure. The surface features can prevent ejection of the access port from a body of a patient. The surface features can be positioned along the access port and configured to glide along body tissues with minimal friction so as not to hinder travel of the access port in an insertion direction. After insertion of the access port, the surface features can engage with surrounding tissue to increase friction therebetween and to prevent ejection of the access port from the patient. Deployment of the surface features can occur due to friction with the surrounding tissue and/or via activation of the surface features to protrude from the access port. The surface features can include teeth, hooks, scales, fins, bristles, braids, and/or threads for engaging tissue. The surface features can be disengaged from the tissue to enable withdrawal of the access port without damaging the surrounding tissue.

A tethered cannula having at least two curved sections for implantation into an eye and a method for implanting the cannula in the eye. The cannula can withstand ever present and changing rotational forces from eye movement and mechanical forces from the movement of the subject. The cannula can be connected to implantable or tetherable devices that are too large, heavy, or obstructive to attach directly to the eye, such as an intraocular pressure sensor or infusion pump.

A trocar adapted for insertion through a fascia layer of an abdominal wall, comprising a proximal end configured for handling by a user; a distal end configured for insertion into tissue; and a shaft extending in between the proximal end and distal end, wherein the shaft comprises a narrow portion proximal to the distal end, the narrow portion defining at least one recess shaped and sized to receive fascia tissue, the recess ending, at a distal end, with a generally proximally facing surface of the shaft configured directly below the narrow portion, the proximally facing surface and the narrow portion shaped and sized to stabilize the trocar in the abdominal wall by the fascia. In some embodiments, a trocar and external cannula assembly are provided. In some embodiments, the trocar and/or trocar and external cannula assembly are configured for deployment of one or more anchors and/or sutures in the tissue.
