Robotic surgical systems have been used in minimally invasive medical procedures. Some robotic surgical systems include a console supporting a robotic arm, and a robotic surgical instrument having at least one end effector (e.g., forceps or a grasping tool) mounted to the robotic arm via a wrist assembly. In some systems, cables extend from the console, through the robotic arm, and connect to the wrist assembly and/or end effector to provide mechanical power to the end effector for its operation and movement.
During a medical procedure, the end effector and the wrist assembly are inserted into a small incision (via a cannula) or a natural orifice of a patient to position the end effector at a work site within the body of the patient. In order to establish and maintain a sterile barrier between the patient, a surgical field, and/or the robotic surgical system, a drape may be used to enclose or sheath a portion of the robotic surgical system.
However, it is often the case that excess draping material may interfere with the medical procedure by interfering with a movement of the robotic arm or robotic surgical instrument and/or getting in the way of medical personnel.
Accordingly, a need exists for a way to contain excess draping material during a medical procedure.
The present disclosure relates to robotics surgical systems, and more specifically, to drape management assemblies for robotic assisted surgery.

Any suitable angle between the respective axes “Y,” “X1,” “X2,” and “X3” is contemplated. For example, the angle between axis “Y” of base portion 310 and axis “X1” of grasping portion 320 may be from about 60 to about 90 degrees, and the angle between axis “X1” of grasping portion 320 and axis “X2” of lip 320a may be from about 80 to about 120 degrees. In embodiments, the angle between axis “Y” of base portion 310 and axis “X1” of grasping portion 320 may be from about 65 to about 75 degrees (e.g., about 71 degrees), and the angle between axis “X1” of grasping portion 320 and axis “X2” of lip 320a may be from about 90 to about 110 degrees (e.g., about 105 degrees).
The base portion 310 and the grasping portion 320 of the clip 302, together with outer surfaces of instrument drive unit 150, may define a cavity or gap 330 therebetween, wherein the base portion 310 and the grasping portion 320 are arranged to retain a quantity of the surgical drape 30 in the cavity or gap 330 of the drape management assembly 300. As such, the drape management assembly 300 minimizes, reduces, or otherwise eliminates an excess quantity 30a (

The drape management assembly 300 may further include an insert 340 configured to selectively couple with the clip 302. The insert 340 may be used, e.g., to enhance the ability of the clip 302 to grip the surgical drape 30, and/or the excess quantity 30a of the surgical drape 30. The insert 340 of the drape management assembly 300 includes a top surface 340a and a bottom surface 340b. Insert 340 includes a plurality of protrusions 342a-342d extending therefrom configured to selectively engage the respective slots 325a-325d, of the clip 302.

In embodiments, the clip 302 of the drape management assembly 300 may be formed of a plastic, steel, stainless steel, sheet metal, or any other suitable material such that the clip 302 is capable of withstanding repeated movements or deflections from an approximated position to an unapproximated position without yielding or deforming. In some embodiments, the clip 302 is plated, e.g., through an electroplating process, with an electroless nickel, bright nickel, chrome, zinc, or the like. In other embodiments, the clip 302 of the drape management assembly 300 may be polished, electropolished, barrel-finished, deburred, or the like, e.g., to smooth out the edges of clip 302, for improved appearance or finish, and corrosion protection, or to inhibit cutting or tearing of surgical drape 30.
In embodiments, the insert 340 of the drape management assembly 300 may be formed of a flexible material configured to conform to the bottom surface 302b of the clip 302 while still being able to provide adequate grip to engage the surgical drape 30. For example, the insert 340 may be formed from silicone, natural rubber, nitrile, urethane, and the like. The insert 340 is more flexible than the clip 302 and may have a durometer of about shore A45 to about shore A55. In some embodiments, the insert 340 may have a durometer of about shore A50.

Clip 500 includes a base portion 510 configured for selective connection to the end portion 20a of the slide rail 20, and a grasping portion 520 extending from the base portion 510 for affixing or pinning the surgical drape 30 (
The base portion 510 of clip 500 defines a pair of apertures (not explicitly shown) therethrough dimensioned for receipt of a pair of fasteners 501, 503 for securing or fixing clip 500 to an outer surface 21 of slide rail 20. In other embodiments, a bottom surface (not explicitly shown) of base portion 510 may have adhesive for securing clip 500 to slide rail 20. When clip 500 is assembled to slide rail 20, clip 500 extends longitudinally along a longitudinal axis defined by slide rail 20, with grasping portion 520 oriented towards end portion 20a of slide rail 20.
Clip 500 may also have an insert 540, similar to insert 340 of
In use, grasping portion 520 may be moved outwardly relative to base portion 510 about elbow 550 to space grasping portion 520 from outer surface 21 of slide rail 20. With grasping portion 520 spaced from outer surface 21 of slide rail 20, excess drape 30 may be positioned within a cavity 530 cooperatively defined by clip 500 and outer surface 21 of slide rail 20. Upon the cavity 530 receiving excess drape 30, the grasping portion 520 is resiliently biased, via elbow 550, toward outer surface 21 of slide rail 20. As grasping portion 520 moves toward outer surface 21 of slide rail 20, insert 540 engages drape 30 to hold drape 30 against outer surface 21 of slide rail 20, thereby preventing excess drape 30 from exiting cavity 530. In accordance with the present disclosure, it is further contemplated that any clip provided herein may include features or the like, which enhance a gripping and retention of a surgical drape 30 against/to the robotic surgical system. Such features may include and are not limited to ribbing, nubs, coatings, over molding, surface texturing, appliques, and the like.
In embodiments, any clip and/or instrument drive unit 150 provided herein, may include one or more sensors configured to detect the presence of surgical drape 30 between the clip and instrument drive unit 150. The sensors may alert a clinician when surgical drape 30 is initially inserted between the clip and instrument drive unit 150, and/or removed from between the clip and instrument drive unit 150. Such sensors may include, for example, contact sensors, optical sensors, RFID sensors, Ferro-magnetic or magnetic tape sensors, strain gauges, or the like.
In some embodiments, any surface of any clip and/or instrument drive unit 150 provided herein may include an elastomeric material or coating (e.g., a rubberized tape and/or paint) to, for example, increase adhesion with surgical drape 30.
In certain embodiments, any clip provided herein may be a multi-tined clip having a substantially fork-like shape such that surgical drape 30 can, for example, be placed between the tines of the clip to prevent bunching of surgical drape 30, or for individual tines of the clip to deflect by varying amounts in order to accommodate various quantities of surgical drape 30 at various locations along a width of the clip.
It should be understood that the foregoing description is only illustrative of the present disclosure. Various alternatives and modifications can be devised by those skilled in the art without departing from the disclosure. Accordingly, the present disclosure is intended to embrace all such alternatives, modifications, and variances. The embodiments described with reference to the attached drawings are presented only to demonstrate certain examples of the disclosure. Other elements, steps, methods, and techniques that are insubstantially different from those described above and/or in the appended claims are also intended to be within the scope of the disclosure.
