Description

[Technical Field]

[0001] (Related Applications) This application claims priority to U.S. Application No. 62 / 543,893, filed August 10, 2017, entitled "Surgical Drape," and U.S. Application No. 62 / 671,320, filed May 14, 2018, entitled "Surgical Drape," the entire contents of which are incorporated herein by reference. [Background technology]

[0002] Surgical systems and devices are used in urological procedures on male patients. For example, in male urological procedures, a transrectal ultrasound (TRUS) probe may be inserted into the patient's rectum in conjunction with the insertion of a handpiece into the urethra. During surgical procedures, it is often necessary to cover or drape both the device and the patient to protect them from contamination with blood or other bodily fluids. While surgical drapes are commonly used to cover the patient's body, conventional drapes and systems for providing a sterile barrier and effective fluid management may not be ideal in at least some respects. For example, conventional drapes for male urological surgical procedures may have a simple, generally flat shape that may not be well suited for use with some surgical systems and transrectal probes, and thus may hinder the mobility of the TRUS probe or a mechanical arm coupled to the TRUS probe. Furthermore, conventional drapes may be opaque, preventing visibility of the surgical site while allowing freedom of movement of the TRUS probe. Also, conventional surgical drapes may allow for the accumulation of more surgical fluid than would be ideal in at least some instances. In some situations, the drape may sag due to the weight of the filled fluid bags attached to it. Additionally, removal of the drape may be more difficult than would be ideal, for example, after a urological procedure when surgical instruments (e.g., catheters) are still in place or catheter anchoring or tensioning devices are in place on the patient.

[0003] In light of the above, it would be desirable to provide a drape that allows for improved ease of use with surgical instruments while reducing interference or obstruction in the operation and movement of the imaging probe. Additionally, it would be desirable to provide a surgical drape that has improved fluid management capabilities and serves as a substantially transparent sterile barrier between the urethra and rectum during urological procedures.

[0107] In the following detailed description, reference is made to the accompanying drawings, which form a part of this specification. In the drawings, like symbols typically identify like components unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the scope of the subject matter presented herein. In general, it will be readily understood that aspects of the present disclosure as described herein and illustrated in the figures can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are expressly contemplated herein.

[0108] The methods and apparatus of the present disclosure are highly suitable for combination with many types of surgical instruments and robotic surgical devices, for example, as described in PCT Application No. PCT / US2013 / 028441, filed February 28, 2013, entitled "AUTOMATED IMAGE-GUIDED TISSUE RESECTION AND TREATMENT" [Attorney Docket No. 41502-705.601], the entire disclosure of which is incorporated herein by reference and is suitable for combination with embodiments disclosed herein.

[0109] As used herein, the terms proximal and distal in the context of the device refer to proximal and distal as referenced to the device outside the patient, and thus proximal can refer to components closer to the outside of the patient or operator, and distal can refer to components inside the patient or further from the operator.

[0110] As used herein, the terms proximal and distal in the context of anatomical locations are relative to the operator of the device, and thus proximal may refer to an anatomical location closer to the operator, and distal may refer to an anatomical location further from the operator.

[0111] As used herein, the terms distal and proximal refer to locations relative to the device, and may be as opposed to anatomical locations. For example, a distal location of the probe may correspond to a proximal location of the patient's elongated organ, such as the patient's penis, and a proximal location of the probe may correspond to a distal location of the patient's elongated organ.

[0112] Although specific reference is made to treating the prostate gland, the methods and systems disclosed herein can be used with many tissues. For example, the embodiments disclosed herein may be used in any urological, gynecological, or proctological procedure. The embodiments as disclosed herein may be used in any surgical procedure for treating any tissue cavity that includes proximal and distal openings that allow the tissue volume to fluidly communicate with other organs or parts of the body adjacent to the tissue volume. For example, although specific reference is made to advancing a hemostatic device through the urethra into the prostate gland and through the bladder neck into the bladder, a hemostatic device as described herein may be advanced into the cavity through any proximal opening of the tissue cavity and through any distal opening of the tissue cavity into another organ or body part adjacent to the tissue volume.

[0113] The surgical system protected by the drape can be associated with administering a hemostatic material or sealant to completely or partially fill any bleeding closed tissue volume. Such tissue volumes can include naturally occurring tissue spaces or gaps, such as aneurysms, fissures, or uterine postpartum bleeding. Such tissue volumes can form, for example, as a result of unnecessary tissue removal or unwanted growths, fluids, cells, or tissues. The surgical system, as utilized in surgical procedures, is well suited for treating closed tissue volumes remaining after tumor resection, endometrial ablation, polyp removal, cyst removal, and the like.

[0114] The surgical systems involved in the surgical procedure may be well suited for treating many types of closed tissue volumes, such as within the rectum, prostate, uterus, cervix, liver, kidney, intestine, pancreas, muscle, and the like.

[0115] The surgical system or at least a portion of the surgical system can be sterilized by conventional methods compatible with the device, such as steam, heat and pressure, chemicals, and the like.

[0116] 1A and 1B show perspective views of a patient 20 and a surgical system 10 partially covered by a sterile drape 100, according to some embodiments. The surgical drape 100 may be substantially flexible and impervious to liquids, such as bodily fluids. The surgical drape 100 may include a first portion 110 coupled to a second portion 130. The second portion may include a non-transparent or opaque portion, and the first portion may include an optically transmissive material, such as one or more of a visually transmissive material, a visually transmissive material, or a translucent material, thereby allowing at least a portion of light to pass through the material, allowing at least partial visualization therethrough. For example, a transparent or translucent material may allow a majority of light within the visible spectrum to pass through, allowing at least partial visualization therethrough. A translucent or semi-translucent material may allow only a portion of visible light or certain wavelengths of light to pass through, thereby resulting in some reduced visibility. The first portion 110 may be at least partially transparent to the visible light spectrum so that a user can see through it to view underlying objects.

[0117] As shown in FIGS. 1A and 1B , a surgical drape 100 may be sized and shaped to cover at least a portion of a surgical system 10. The surgical system 10 may include an imaging probe 12 for imaging tissue within a patient's body. The imaging probe 12 may include, for example, an ultrasound probe. The imaging probe may include a transrectal ultrasound (TRUS) or other imaging modality for providing real-time image guidance to a physician during a surgical procedure. The imaging probe 12 may be coupled to an articulating or mechanical arm 14 configured to support and / or actuate the imaging probe. For example, the imaging probe may be operably coupled to a distal portion of the mechanical arm, and a proximal portion may be coupled to a surgical table or stand. The mechanical arm may be configured to provide one or more degrees of freedom of movement to the imaging probe. For example, the mechanical arm can be used to move the imaging probe along a longitudinal axis toward a target tissue of a patient.

[0118] The surgical drape 100 may include a first portion 110 including a canopy portion 111. Some or all of the first portion 110 may include a visually transparent or translucent material. In some cases, a portion of the first portion 110 may be visually transparent or translucent, while another portion of the first portion may be opaque. The canopy portion 111 may preferably include a visually transparent or translucent material. The canopy portion 111 can be provided or disposed anywhere on the first portion 110, for example, at the center, edges, corners, top, bottom, and / or sides of the first portion. The canopy portion 111 can be integrally formed with or as part of the first portion 110. Alternatively, the canopy portion 111 may be provided as a separate piece from the first portion 110 such that the canopy portion can be fixedly or removably coupled to the first portion. In some cases, the first portion 110 may include a cutout or opening configured to couple to the canopy portion 111. For example, the cutout or opening in the first portion may be sized and shaped to match canopy portion 111, as described elsewhere herein.

[0119] The canopy portion 111 may be sized and shaped to substantially cover the proximal end of the imaging probe 10. In some embodiments, the canopy portion 111 may comprise a three-dimensional configuration that provides a workspace within which the imaging probe 10 can move in an unrestricted manner, e.g., with less physical obstruction or interference. The imaging probe may be an ultrasound imaging probe having a proximal portion 12-1 supported by an articulating or mechanical arm 14. The first portion 110 or the canopy portion 111 may be configured to at least partially cover the mechanical arm coupled to the ultrasound imaging probe and / or the proximal portion of the ultrasound imaging probe. The surgical drape 100 may also comprise a second portion 130 coupled to the first portion 110. The first portion 110 and the second portion 130 may be fixedly or removably coupled to each other. The second portion 130 may be sized and shaped to cover at least a portion of the patient's torso 22. As described above, the second portion 130 may be a non-transparent or opaque portion, although the invention is not limited thereto. In some cases, one or more portions of second portion 130 may be visually clear or translucent.

[0120] The surgical drape may cover at least a portion of the imaging probe's articulating or mechanical arm 14. In some cases, the entire imaging probe, including the articulating arm and the base from which it extends, may be covered by the surgical drape. In some situations, the entire imaging probe may be covered by the drape to create a sterile barrier and physically separate the imaging probe from the patient's surgical area.

[0121] As previously mentioned, the surgical drape may be compatible with surgical systems utilized in male urological surgical procedures or prostate surgery. In some embodiments, the surgical system may include a treatment probe 16 (e.g., shown in FIG. 1B ) and an imaging probe. The patient may be positioned on a patient support (e.g., an examination table or operating table) so that the treatment probe and imaging probe (e.g., an ultrasound probe) may be inserted into the patient. The patient may be positioned in one or more of a number of positions, such as prone, supine, upright, or inclined. In some embodiments, the patient may be positioned in a lithotomy position, e.g., stirrups may be used. The treatment probe and imaging probe may be inserted into the patient in one or more of a number of ways. In some embodiments, the imaging probe may be inserted into the patient's rectum and the treatment probe may be inserted into the patient's urethra, and the drape disclosed herein may provide a transparent sterile barrier between the urethra and the rectum. In some situations, the imaging probe is not sterilized and a sterile barrier may be provided to physically separate the imaging probe from the patient's surgical area.

[0122] In some cases, insertion of a treatment probe (e.g., a sealant delivery device, a tissue resection device) and / or delivery of a sealant to a cavity or tissue may be guided by an imaging probe. The imaging probe may be an ultrasonography probe. The imaging probe may be equipped with a transrectal ultrasound (TRUS) or other imaging modality to provide visual guidance. The TRUS may be used to guide actuation of the catheter during sealant delivery, for example, by retracting or advancing the catheter within the cavity by mechanical or manual means.

[0123] In some embodiments, the treatment probe may comprise a handpiece. In some cases, the treatment probe may be configured to image the target tissue. The treatment probe may comprise an elongated structure having a working channel sized and shaped to receive an endoscope and a delivery tube carrier. The carrier may be configured to direct and scan a light beam over the treatment area and determine the contours of the tissue to be removed. The carrier may also be configured to emit a fluid stream with a waveguide and scan the light pattern of the fluid stream with the waveguide. The treatment probe may be a urethral probe for volumetric tissue removal. For example, the treatment probe may direct a fluid stream radially outward for controlled ablation of tissue such as prostate and luminal tissue. Optionally, the fluid stream may be used to deliver light, electricity, heat, or other energy sources to assist in ablation and / or cauterize the tissue to be treated. Alternatively, the treatment probe may be any tool or robotic device capable of performing or assisting in urological surgery, with or without manual operation.

[0124] The imaging probe may include or be supported by an articulating or mechanical arm 14 extending from a base. The mechanical arm may be connected to the proximal end 12-1 of the elongated imaging probe 10. In some embodiments, the articulating or mechanical arm may include an actuator 117 for manipulating the imaging probe under user control. In some cases, the entire base or articulating arm, or at least a portion thereof, may be covered by a drape, and the proximal end of the imaging probe may be entirely covered by a canopy portion of the drape. For example, as shown in FIGS. 1A and 1B, the proximal end of a TRUS probe may be covered by a canopy portion of a first portion of a surgical drape, and the articulating arm may be covered by a non-canopy portion of the first portion.

[0125] An imaging probe, for example, the distal portion 12-2 of the imaging probe 10, can be inserted into a patient in one or more of many ways. The imaging probe can comprise an ultrasound probe. A proximal portion of the ultrasound probe can be mounted on an articulating or mechanical arm 14, and the distal portion 12-2 of the ultrasound probe can be inserted into the patient. During insertion, the articulating arm 14 can have a substantially unlocked configuration so that the imaging probe can be desirably rotated and translated to insert the distal portion 12-2 of the probe into the patient. When the imaging probe has been inserted into a desired location within the patient, the articulating or mechanical arm 14 can be locked. In some cases, the imaging probe and treatment probe can be inserted into the patient sequentially or concurrently. In the locked configuration of the imaging probe, the imaging probe and / or treatment probe can be oriented relative to one another in one or more of many ways, such as, for example, parallel, oblique, horizontal, oblique, or non-parallel. It may be useful to determine the orientation of the probe using a sensor, such as an angle sensor, to map the imaging probe's image data to the treatment probe's coordinate reference space. Mapping tissue image data to the treatment probe's coordinate reference space can enable precise targeting and treatment of tissue identified for treatment by an operator, such as a physician. Therefore, it is ideal for the imaging probe to be able to move unhindered and with little restriction while covered by surgical drapes.

[0126] In some embodiments, the treatment probe 16 may be coupled to the imaging probe to align the treatment probe with the treatment probe based on images from the imaging probe. Coupling can be achieved using a base that is common to the treatment probe and the imaging probe. The imaging probe can be coupled to the base using an articulating or mechanical arm 14 that can be used to adjust the alignment of the imaging probe when the treatment probe is locked in place. The articulating or mechanical arm 14 may comprise a lockable and movable probe under control of, for example, an imaging system or console and user interface. The articulating or mechanical arm 14 may be micro-actuable so that the proximal end 12-1 of the imaging probe 12 can be adjusted relative to the treatment probe with small movements, for example, on the order of one millimeter.

[0127] The movement of the imaging probe 12 or the proximal end 12-1 of the imaging probe can range from a few millimeters to a few centimeters. For example, the proximal end of the imaging probe may move within a space having dimensions (e.g., length, width, height, diameter, diagonal) of at least 10 cm, 20 cm, 30 cm, 40 cm, 50 cm, 60 cm, 70 cm, or 80 cm. The proximal end of the imaging probe may be configured to move freely with up to six degrees of freedom (e.g., three degrees of freedom in translation and three degrees of freedom in rotation).

[0128] 1A and 1B, canopy portion 111 provides a workspace or volume 114 for imaging probe 12 to move within with reduced restriction. Workspace 114 is useful for reducing physical interference between the imaging probe and the drape as the imaging probe moves. In some cases, the canopy portion may be configured to move with the proximal end of imaging probe 12 as a whole while the remainder of the drape remains supported in place. Additional details regarding the canopy portion are described later in this specification.

[0129] The surgical drape 100 may include an opening or fenestration 118 that allows access to the urethra by a treatment device or probe. The fenestration 118 may allow access to an organ that is isolated from the remainder of the patient's body that is covered by the drape. Alternatively, the fenestration 118 may allow access of surgical instruments through the drape. The opening or fenestration may be a through-hole formed in the surgical drape second portion 130 or the surgical drape first portion 110. The opening or fenestration may be located adjacent to the canopy portion 111 in some embodiments.

[0130] The surgical drape may be removable from the patient or surgical system. Removal of the drape can be accomplished by perforations 132, which can extend along the midline of the drape to the fenestration or at any angle thereto. This is useful for providing easy removal of the drape after a urological procedure while an instrument, such as a catheter, is still in place. In some embodiments, the perforations 132 need not extend along the midline of the drape but may be offset from the midline of the drape by a distance, e.g., approximately 5 cm, 10 cm, 20 cm, 30 cm, 40 cm, or 50 cm. In some cases, the perforations may include various other mechanisms, such as zippers, buttons, sliders, ripcords, and the like.

[0131] The surgical drape may further include a container portion 140 for receiving waste products generated during a surgical procedure. For example, in male urological procedures, it is common for a significant amount of fluid to be released from the urethra or other instruments. The container portion 140 may be a collection reservoir for bodily fluids and irrigation fluids that flow from the patient during examination and surgery. In some embodiments, the container portion 140 may include holes 142 that allow bodily fluids to exit therefrom. The container portion 140 may include a drainage area and / or a funnel that can direct bodily fluids and irrigation fluids to another container located below the container portion. Additionally, the container portion 140 may provide effective fluid management and may be compatible with a suction irrigation system. In some cases, the container may include an opening and be configured to receive and store waste products, including bodily fluids, surgical-related fluids, tissue, or debris, generated during a surgical procedure.

[0132] The surgical drape may include an attachment 150 to help position and support the container portion 140, especially when the container holds fluid that contributes additional weight to the container. The attachment may be a component of the surgical drape or the container portion. The attachment may be a stand-alone element that is releasably attached to the surgical drape or the container portion. The attachment is useful for supporting the container portion when the container holds fluid. For example, in the event of a malfunction in the suction and irrigation system, a significant amount of fluid may be deposited into the container, and the drape may sag downward due to the weight of the liquid in the container. The attachment 150 may include a tether or strap to support the container and prevent the drape from sagging. The tether or strap can be attached from the open side of the container portion to the patient's leg 24 or the operating table. For example, the strap or tether can be wrapped around the patient's leg 24 over the drape or affixed to the operating table. The tether can be connected to a bed rail, a surgical arm, or the surgeon. In some cases, the strap or tether may be attached to the physician's clothing / surgical gown or to a halter worn by the physician around his or her neck. In some cases, the attachment may include a U-ring device configured to attach to one side of a surgical table or the end of the surgical table. Thus, the attachment 150 can allow the weight of the container portion to be partially supported by the patient's legs or the surgical table. The patient's legs may be covered by the second portion 130 or the first portion 110 of the drape. The patient's legs may or may not be visible to the physician through the drape.

[0133] FIG. 2 illustrates a first portion 110 of a surgical drape, according to some embodiments. The first portion 110 may comprise a single sheet of material, such as an extruded or coextruded material, or multiple sheets of material. In some embodiments, the first portion may comprise multiple sheets of the same material stacked together. In other embodiments, the first portion may comprise multiple sheets of different materials stacked or sandwiched together. The first portion 110 may comprise a visually transparent or translucent portion. The first portion may comprise, for example, a clear plastic or latex thin film. The first portion may or may not have a color. The first portion may be clear without a color. Alternatively, the first portion may have a color, such as blue, green, yellow, red, or any other color. The first portion may comprise a uniform color or a mixture of various different colors. The sheet of material used for the first portion may be constructed from readily available plastic films used in the medical field, such as vinyl (such as polyvinyl chloride), polyethylene, polypropylene, polycarbonate, polyester, silicone elastomer, acetate, etc.

[0134] The sheet of material used for first portion 110 may be a transparent or translucent material that allows a user to see through the portion during insertion or operation of the imaging probe. The sheet of material may be translucent, thereby allowing at least a portion of light to pass through the material. The sheet of material may be at least partially transmissive to the visible light spectrum so that a user can see through the portion to view underlying objects. The sheet of material may also allow visual visibility of non-sterile instruments inserted into a patient, such as an imaging probe.

[0135] The sheet of material used for the first portion 110 may be impervious to liquids. For example, the material may be hydrophobic to prevent moisture absorption by the drape. The sheet of material used for the first portion may possess a desired stiffness or flexibility so that an operator can move an articulating arm coupled to the imaging probe without tearing the first portion. The sheet of material used for the first portion may be configured to have a predetermined flexural stiffness or a range of flexural stiffness values. In another example, the sheet of material may have a tensile modulus in the range of 0.1 GPa to 5 GPa, where GPa refers to the tensile modulus in gigapascals, as will be understood by those skilled in the art. A material may be of a harder grade when the tensile modulus is greater. A material may be flexible or soft when the tensile modulus is small.

[0136] When selecting a sheet material for use in the first section, factors such as the sheet's softness, breathability, the sheet's conformance to the patient's body contours, patient comfort, or canopy stiffness can be evaluated in conjunction with the sheet's thickness. For example, a sheet made from a softer material may be provided having a greater thickness than a sheet made from a harder grade of material to provide a similar stiffening effect. The type of material and its thickness may be selected so that the canopy portion of the first section can be configured to collapse to less than its full volume when the canopy portion is covering the proximal portion of an imaging probe, e.g., an ultrasound probe. Additionally, the type of material and its thickness may be selected so that an operator can manipulate an articulating arm through the surgical drape without tearing any portion of the drape. In some embodiments, the canopy portion or first section of the drape may comprise a thin, flexible material having a thickness ranging from about 0.05 mm to about 3 mm, e.g., from about 0.25 mm to about 3 mm. Alternatively, the thickness of the first portion or canopy portion may be less than 0.25 mm or greater than 3 mm. For example, the thickness of the first portion, including the canopy portion, may comprise a thin, flexible material having a thickness in the range of about 0.05 mm to about 3 mm.

[0137] The first portion may comprise a canopy portion 111. The canopy portion 111 may have a shape and dimensions for covering at least the proximal end of the imaging probe, as described elsewhere herein. The canopy portion 111 may comprise a three-dimensional space 114 sized and shaped to cover the proximal portion of the imaging probe so that the imaging probe is allowed to move in an unrestricted manner within three-dimensional space. The space 114 provided by the canopy portion may be sufficient to accommodate movement of the imaging probe without the canopy portion or other portions of the drape interfering with the movement of the imaging probe. The space 114 provided by the canopy portion may be larger than the working space required by the imaging probe. The canopy portion can be adapted for imaging probes of different sizes and dimensions. For example, the space provided by the canopy portion may be at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, or more larger than the size or dimensions of the imaging probe. The space provided by the canopy portion may be defined by a volume, for example, 30-50 cm x 10-30 cm x 10-30 cm. The three-dimensional space may be approximately 750 cm. 3 ~Approx. 70,000cm 3 In some cases, the volume of the three-dimensional space may be 750 cm 3 may be less than or equal to 70,000 cm 3Alternatively, the space provided by the canopy portion may be defined by a volume of at least 40 cm x 45 cm x 25 cm, 45 cm x 45 cm x 30 cm, or 50 cm x 50 cm x 30 cm, or larger. The canopy portion may comprise a space having a volume greater than the volume occupied by the proximal portion of the ultrasound inspection probe. For example, the volume of the space provided by the canopy portion may be at least twice as large as the volume occupied by the proximal portion of the ultrasound inspection probe. The canopy portion may comprise any type of material, shape, and / or dimensions that allow the canopy portion to collapse to less than its full volume in a freestanding configuration such that the canopy portion may wrap around or cover the proximal portion of the ultrasound inspection probe. The canopy portion is described as being in a freestanding configuration when the canopy portion is not covering any underlying object and is allowed to collapse to a generally flattened shape under its own weight. It should be noted that the three-dimensional spatial volume of the canopy portion may be substantially reduced when the canopy portion is in the freestanding configuration (compared to when the canopy portion covers the imaging probe or a proximal portion thereof). In some cases, the three-dimensional spatial volume of the canopy portion may be reduced by 50%, 60%, 70%, 80%, 90%, or more than 90% when the canopy portion is in the freestanding configuration.

[0138] The canopy portion 111 may have any three-dimensional shape, such as a cube, sphere, cylinder, cone, hemisphere, rectangular prism, triangular prism, hexagonal prism, pyramid, self-supporting geodesic dome, and various other forms. In some cases, the canopy portion may have a rectangular or rectangular shape. The three-dimensional shape of the canopy portion may have any number of faces or edges where adjacent faces meet. For example, the three-dimensional shape may include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more faces. The three-dimensional shape of the canopy portion can be formed using any manufacturing or processing method known to those skilled in the art. For example, the canopy portion can be formed by a thermoforming process to form a sheet of plastic material into the desired three-dimensional geometric shape, or by joining multiple pieces of material together, such as using heat sealing.

[0139] In some cases, the first portion 110 may include a base portion 116 connected to the canopy portion. The base portion 116 may be an outer section of the first portion. The base portion may be a generally flat portion of the first portion and may be configured to wrap around at least a mechanical arm coupled to the ultrasound inspection probe or a proximal portion of the ultrasound inspection probe such that the canopy portion moves collectively with the mechanical arm and the proximal portion of the ultrasound inspection probe. The canopy portion 111 may include a separate sheet of material attachable to the base portion 116. The first portion may include a first sheet of material, and the canopy portion 111 may include a second sheet of material that may or may not be identical to the first sheet of material. The canopy portion 111 may be attached to the outer section or base portion 116 of the first portion 110. For example, the edge of the opening in the canopy portion may be sealed or sewn to the inner edge 124 of the outer section or base portion 116 of the first portion. The inner edge 124 may also be referred to as the inner cutout of the outer section of the first portion. The inner cutout 124 may have a shape and dimensions to fit the opening in the canopy portion. The canopy portion can be coupled to the outer section of the base portion in various ways. For example, the edge of the opening in the canopy portion may include a flange to seal the canopy portion to the inner cutout of the outer section of the base portion 116. The inner edge or inner cutout 124 of the outer section of the first portion or the base portion 116 may define an aperture 122 therein. The canopy portion may be attached to the outer section of the first portion or the first portion 116 to cover the aperture 122. Alternatively, the canopy portion may be integrally formed with the first portion. For example, the canopy portion may be formed from the same sheet of material as the first portion. The canopy portion may be visually transparent or translucent to allow viewing of the imaging probe and / or alignment of the probe to the patient's body.

[0140] First portion 110 may be coupled to second portion 130 and receptacle portion 140 of drape 100. Figure 3A provides a top plan view of drape 100 as seen from above the patient, and Figure 3B provides a perspective view of drape 100.

[0141] In some embodiments, the first portion 110 may include a fenestration 118 sized and shaped to receive a treatment probe inserted into the patient's urethra. Alternatively, the fenestration 118 may be formed in the second portion 130. In some cases, the fenestration 118 may be formed in the first portion 110 above the canopy portion 111. The first portion 110 may allow visualization of the ultrasound probe and maintain the sterility of the treatment probe when it is inserted into the patient's urethra. The fenestration 118 may be formed to have any shape, such as circular, rectangular, square, and various others. The fenestration 118 may have any dimension. For example, the fenestration may have a diameter or length within a range of approximately 1 cm to 20 cm.

[0142] In some cases, the fenestration 118 may include a reinforcing element 120 attached to the periphery of the fenestration to provide reinforcement for the insertion of an instrument or male genitalia. The reinforcing element 120 may include a septum surrounding or partially surrounding the fenestration. The reinforcing element may include a material that possesses flexibility and rigidity similar to, or may be softer or more rigid than, the material used for the fenestration / transparency. The reinforcing element may include an opaque, translucent, or transparent material, which may provide visual contrast to enhance identification of the fenestration. The reinforcing element may be flexible or elastic and may include a material that possesses sufficient rigidity to prevent instruments, such as a treatment probe, from penetrating or tearing the drape. In some cases, the reinforcing element may include elastic gathers that tighten around the organ to maintain the integrity of the sterile field. Alternatively, the reinforcing element may include an adjustable closure for tightening around the organ to maintain the integrity of the sterile field. Additionally or optionally, the reinforcing element may include an adhesive material for gathering and attaching the drape around the organ to maintain the integrity of the sterile field.

[0143] The surgical drape may include a reservoir portion 140 for managing fluids generated during a surgical procedure. The reservoir portion 140 may comprise a sheet of material that is impermeable to liquids. The reservoir portion 140 may be removable or releasably attached to another portion of the drape. For example, the reservoir portion may be a liquid pouch that may be attached to the lower portion of the drape below the canopy portion. The liquid pouch may be attached to the drape via any suitable means, such as, for example, a strip, ribbon, button, self-adhesive strip, or tab. Alternatively, the reservoir portion 140 may be integrally formed with the first portion. In some embodiments, the reservoir portion 140 and the first portion of the drape may be formed from the same sheet of material. In some cases, the reservoir portion 140 may include a seamed edge 146 such that a sheet of material in a triangular shape may be folded and seamed at the seamed edge to form the pouch. Alternatively, the reservoir portion 140 may not be seamed and formed. As illustrated in FIG. 3A, a reservoir portion 140 may be positioned below the canopy portion 110 to receive downwardly flowing fluid.

[0144] The container portion 140 may comprise any shape that assists in collecting and / or directing fluid to flow toward the exit port. In some embodiments, the container portion may comprise a generally conical funnel shape to allow fluid to drain into the exit port. In another example, the container portion may comprise a generally rectangular form with an angled or sloped bottom to allow fluid to drain into the exit port.

[0145] The container portion 140 may include a drainage area and / or a funnel for directing bodily fluids and irrigation fluids to another container or a suction system (not shown). For example, the container portion may include a screen 148 attached to the inside of the lower portion of the container portion, allowing bodily fluids to pass through. The screen 148 may include a mesh with pores to prevent blockage of the exit port 144. The pore size may vary, for example, from 1 mm to 20 mm. In some cases, waste is passed through the screen, and the screen is configured to collect tissue or debris generated during the surgical procedure. In some cases, the debris or tissue collected by the screen may be used for further diagnosis or analysis. In some cases, if the container portion protrudes, the screen may come together to allow airflow to the exit port. In some cases, the screen 148 may be removable from the container portion, sealed, and used as a storage container for containing collected samples. In some cases, the screen 148 may have sides made from a material that is impervious to liquids to eliminate droplets during storage or transport. In some cases, the screen may have a closure (such as a zipper, ziplock, adhesive seal, drawstring, clip, elastic or conformable wire, etc.) to secure the collected sample for storage or transport. In some cases, the screen 148 may include a transparent portion that is compatible with imaging modalities for tissue analysis.

[0146] The container portion can provide effective fluid management and can be compatible with a suction irrigation system. In some embodiments, a suction irrigation system can be provided, and the container portion can include an exit port 144 at the bottom of the container configured to connect to the suction irrigation system. For example, the container portion can include an exit port with a sealing flange at the bottom of the container portion for connection to a suction irrigation system (not shown).

[0147] The container portion 140 may include an attachment 150 for supporting the container when it holds fluid. The attachment 150 may be used to attach the opening of the container portion to the upper portion of the non-transparent portion of the drape to support the fluid-holding container. The attachment 150 may include a strap or tether to prevent the drape from sagging. For example, the strap or tether may be used to attach the open side of the container portion to the patient's leg or the operating table. For example, as shown in FIG. 3C, the strap or tether 150 may be wrapped around the patient's leg 24 over the drape. The strap or tether may also be attached to the patient using adhesive tape provided on the end of the strap or tether 150. Alternatively, the strap or tether can be attached to the operating table, a structure mounted on the operating table, or the drape. The strap or tether can be rolled up or folded prior to use (as shown in FIG. 3A). For example, the strap or tether may be folded and secured with adhesive tape 152 prior to use. The strap or tether 150 may have a length of at least 50 cm, 100 cm, 120 cm, 130 cm, 140 cm, 150 cm, 160 cm, 170 cm, 180 cm, 200 cm, or 250 cm. Any number or type of attachment can be used to hold the container portions in place. While the illustrated invention shows two tethers attached to either side of the container opening, any number of tethers (e.g., two or more) or any form of attachment (e.g., adhesive, tethering mechanism, Velcro®, etc.) may be used to support the container portions.

[0148] The surgical drape 100 may include a second portion 130 coupled to the first portion 110. The second portion may be an opaque or non-transparent portion. The non-transparent portion may comprise a standard medical non-woven disposable material or may be more opaque to provide privacy for the patient. The non-transparent portion may comprise a material that is impervious to liquids. The non-transparent portion may be sized and shaped to cover the patient's torso 22. The non-transparent portion may be sized and shaped to substantially cover at least a portion of the patient's body and the surgical system. For example, the non-transparent portion may cover a portion of the imaging probe. In some embodiments, the non-transparent portion may further include features, such as slits 136 as shown in FIG. 3A, to provide flexibility. The non-transparent portion may comprise any shape, such as a rectangle, a triangle, a square, or any other irregular shape.

[0149] The first portion 110 and the second portion 130 may be removably coupled to one another. Alternatively, the first portion 110 and the second portion 130 may be formed together as a unitary piece. The first portion 110 and the second portion 130 may be sewn together as a unitary piece. In some embodiments, as illustrated in FIG. 3A , the first portion may be coupled to a cutout 134 in the second portion. The cutout may allow a surgical system or imaging probe to be more easily viewed by an operator through the first portion.

[0150] The second portion 130 may be configured to cover or wrap around the patient's legs 24. The non-transparent portion may be wrapped around the patient's legs as leggings, such that tethers or straps for holding the container portion (as shown in FIG. 3C) can be affixed to the legs by wrapping them over the leggings. The second portion 130 may or may not extend all the way to the floor.

[0151] The surgical drape 100 may include a separable line or perforation 132 along the midline of the surgical drape or at any angle relative to the midline of the surgical drape. The perforation 132 may extend from the edge of the non-transparent portion to the fenestration. Alternatively, the perforation may not extend to the fenestration. The perforations may aid in the removal of the drape after a urological procedure when an instrument, such as a catheter, is still in place. The perforations may also allow for easy separation of adjacent surfaces of the surgical drape. In some embodiments, the perforations may include a section 132-1 located on the first portion 110 of the drape and a second section 132-2 located on the second portion 130 of the drape. In some embodiments, the perforations need not be located along the midline or centerline of the surgical drape. The perforations can be positioned anywhere on the drape in a configuration that allows the drape to be split from one side through the fenestration without interference with an instrument placed through the fenestration. In some cases, tape 133 may be used to reinforce the perforated area. The tape 133 may serve to provide a sealed barrier. The tape 133 may be applied to one or both sides of the area where the perforation will be formed. The tape 133 may be placed above and / or below the perforation, and the tape may be impervious to fluids. For example, the tape may include a first layer of tape above the perforation and a second layer of tape below the perforation, such that the perforation is sandwiched between the first and second tape layers. In cases where other mechanisms, such as zippers, buttons, or sliders, are used, tape may also be applied to provide a seal. In some cases, the perforations include a sliding dovetail mechanism that releasably opens and closes the perforation.

[0152] The surgical drape 100 can be folded into a compact package. The folded drape may be secured within an outer wrap or by adhesive tabs. The outer wrap or adhesive tabs may be removed when the package is unfolded.

[0153] 4A-4C illustrate a method of using the surgical drape 100 with a patient 20 and a surgical system. As shown in steps A and B, the surgical drape 100 may be unfolded toward the patient's head, and the drape fenestration 118 may be positioned over the patient's surgical area. Next, a second portion 130 of the drape may be applied over the patient's legs 24 as leggings. The second portion 130 may be wrapped around and covering the patient's legs 24, as shown in step C. The second portion 130 may also cover the patient's torso 22. Proceeding to step D, a first portion of the drape 110 may be unfolded to substantially cover an imaging probe (not shown) of the surgical system, and the receptacle portion 140 may be positioned in position below the surgical area. The first portion of the drape 110 provides less physical interference or obstruction to the movement of the imaging probe. The visual transparency of the first portion of the drape 100 also allows the underlying site or tool to be viewed. The container portion 140 includes an attachment, such as a strap or tether 150, for attaching the container portion to a patient's leg or a surgical table, as described elsewhere herein. The strap helps to hold the container portion on a more stable support. As shown in step E, the tether or strap 150 may include an adhesive tab to keep the tether or strap folded and compacted when not in use. When in use, the tether or strap may be extended and wrapped around the leggings of the surgical drape. When not in use, the tether or strap 150 may be secured in place by placing adhesive tape over the top of the strap or tether, as shown in step F. In some cases, the container portion may be configured to connect an exit port of the container portion to a suction irrigation system to remove fluid from the container portion. The surgical drape 100 can be easily removed by separating along the perforations once the surgical process is completed.

[0154] 4A-4C illustrate methods of using surgical drapes according to some embodiments, those skilled in the art will recognize many adaptations and variations, for example, some of the steps can be omitted, some of the steps can be repeated, and the steps can be performed in any suitable order.

[0155] FIG. 5 illustrates a surgical drape including one or more frame structures 160, which can be combined with any embodiment disclosed herein. The frame structure can be adapted to structurally maintain one or more configurations of the surgical drape. For example, the canopy portion 111 may include one or more frame structures 160 to maintain or provide the workspace / volume 114. The frame structure may be positioned in any location or on one or more portions of the drape. In some cases, the frame structure 160 may extend in an arcuate manner along the sidewall of the canopy portion 111, as shown in FIG. 5, for example. In some embodiments, the frame structure may include a liner 161 along the opening of the container portion 140. The frame structure can be made from any suitable material, such as metal, steel, plastic, fiberglass, and the like. In some cases, the frame structure can be folded and unfolded / deployed to support a variety of different configurations. The frame structure may include or utilize spring steel or any other type of resilient structure. In another example, the framework may include or utilize flexible stiffening elements integrated into the drape material. In some embodiments, at least one of the first portion 110 or the second portion 130 of the surgical drape 100 may be operably coupled to an actuation element (not shown). The actuation element can be configured to deploy one or more sections of the surgical drape from a compact configuration to an extended configuration. The compact configuration may have a generally two-dimensional shape / profile, and the extended configuration may have a generally three-dimensional shape / profile. The surgical drape may be in the compact configuration when the drape is not in use. The surgical drape can be deployed to the extended configuration prior to or during use of the drape for a surgical procedure on a patient. The extended configuration may correspond to a usable state / position for the drape. The actuation element may be integrated into or included with the surgical drape. In addition to deployment, the actuation element can also provide structural reinforcement to one or more sections of the surgical drape (e.g., canopy portion 111) in the extended configuration. Thus, the actuation element may comprise one or more stiffening elements.In some embodiments, the frame structure 160 shown in FIG. 5 may be or form part of an actuating element.

[0156] The actuating element may comprise a stored energy device. The actuating element may include one or more spring elements. Non-limiting examples of spring elements may include various suitable spring types, such as nested compression springs, buckling posts, conical springs, variable pitch springs, snap rings, double torsion springs, wire forms, limited-travel extension springs, braided wire springs, etc. Additionally, the actuating element (e.g., spring element) can be made from any of several metals (e.g., spring steel), plastics, or composite materials. In some cases, the actuating element may include a fiberglass or plastic stiffener, which also serves as a stiffening element as described elsewhere herein.

[0157] In some cases, the one or more spring elements may include a deployment spring positioned to deploy one or more sections of the surgical drape from a compact configuration to an extended configuration. Similarly, the one or more spring elements may include a retraction spring positioned to retract one or more sections of the surgical drape from an extended configuration back to the compact configuration. In some cases, a monolithic spring can be configured to provide dual functionality, e.g., (1) to deploy one or more sections of the surgical drape and (2) to retract it. For example, the monolithic spring can be configured to transform between two or more states (fully compressed, partially extended, fully extended, etc.).

[0158] In any of the embodiments disclosed herein, the actuating element may include a magnet, an electromagnet, a pneumatic actuator, a hydraulic actuator, a motor (e.g., a brushless motor, a direct current (DC) brush motor, a rotary motor, a servo motor, a direct drive rotary motor, a DC torque motor, a linear solenoid stepper motor, an ultrasonic motor, a geared motor, a reduction motor, or a piggyback motor combination), a gear, a cam, a linear drive, a belt, a pulley, a conveyor, and the like.

[0165] The vessel portion 140 (hereafter referred to as the vessel) may comprise a funnel shape to allow fluid to drain into the exit port 144. The vessel 140 may comprise a generally conical funnel shape 156, for example, as shown in FIG. 7. Alternatively, the vessel 140 may comprise a generally rectangular funnel shape 158, for example, as shown in FIG. 8. In some embodiments, the vessel 140 may comprise an angled or sloped (147) bottom portion, for example, as shown in FIG. 8. The angle or slope can be designed to enhance fluid flow toward the exit port 144.

[0166] In some embodiments, the container may include a structure for supporting one or more features of the container. Figures 9A and 9B illustrate a container having a generally rectangular funnel shape with an angled or sloping bottom, according to some embodiments.

[0167] The support structure can include an interleaved structure, such as vertical pleats 143 as shown in FIG. 9A or horizontal pleats 145 as shown in FIG. 9B. The vertical pleats 143 can act as or function as stiffeners to prevent the container 140 from collapsing and changing its shape / form when under load. Additionally or optionally, the vertical pleats 143 can be configured to allow airflow to expel displaced fluid when fluid is being extracted or drained from the container 140. Referring to FIG. 9B, the horizontal pleats 145 can enable the container 140 to collapse in a telescopic manner or to a compact configuration. The container may be collapsible into a generally planar configuration and extendable into a generally three-dimensional configuration using the horizontal pleats 145. The container 140 may include one or more flexible, semi-rigid, or rigid materials. The container 140 can be designed to achieve various desired properties, such as strength, rigidity, resilience, compliance, and durability. Non-limiting examples of materials may include fabrics, silicones, polyurethanes, silicone-polyurethane copolymers, polymer rubbers, polyolefin rubbers, hydrogels, semi-rigid and rigid materials, elastomers, rubbers, thermoplastic elastomers, thermoset elastomers, elastomer composites, rigid polymers including polyphenylene, polyamides, polyimides, polyetherimides, polyethylene, epoxies, partially absorbent materials, and the like.

[0168] In any of the embodiments disclosed herein, the container 140 can be configured to serve as a packaging enclosure for storing the surgical drape 100, or a portion thereof. The packaging enclosure can be used to store the surgical drape, or a portion thereof, when the surgical drape is in its original state prior to use. Additionally, or alternatively, the packaging enclosure can be used to store the surgical drape, or a portion thereof, for subsequent processing after the surgical drape has been used. FIGS. 10A-10D illustrate an embodiment in which the container 140 can be used as a packaging enclosure 170 for storing the surgical drape 100. Referring to FIG. 10A, the drape 100 can be coupled to the container 140 or can extend outside the container. Prior to storing the drape, the drape can be stretched to a generally planar configuration 172. The drape may then be folded in the manner shown in FIG. 10B by folding opposing ends 174-1 and 174-2 of the drape inwardly about longitudinal axis 175. The drape may then be further compacted by folding end 176 inwardly about transverse axis 177, as shown in FIG. 10C. Finally, the drape may be folded and packed into a container for storage, as shown in FIG. 10D. The drape may be stored in the container when new (i.e., prior to use of the drape) and may be shipped in the container. Additionally, or optionally, the drape may be stored in the container after the drape has been used (e.g., in a surgical procedure) for subsequent processing or transportation to a processing facility. In some embodiments, the container may include a lid (not shown) for covering the drape stored in the container.

[0169] In any of the embodiments disclosed herein, the container 140 can be coupled to and supported by a user, e.g., carried by the user 26, as shown in FIG. 11 . The user may be, for example, a surgeon, and the container can be coupled to the user in many ways, e.g., using a strap or tether, such that the user at least partially supports the container. In the example of FIG. 11 , the container can be coupled to a halter 180 configured to be worn on or around the user's neck 28, and the container can be supported by the halter around the user's neck when in use, for example. In some cases (not shown), the container can be coupled to a belt configured to be worn around the user's waist. In some embodiments, the container can be releasably attached to the user's surgical gown using one or more quick-release couplings 154. The use of quick-release couplings can help improve operating room efficiency, for example, by facilitating container portability and exchange of used / new containers within the operating room. Examples of quick-release couplings may include mechanical couplings, snap fits, adhesives, tape, fasteners, magnets, and the like. The container may be releasably coupled to any portion of the user's surgical attire in a manner that aids in waste disposal and does not impede the user's movement during the surgical procedure.

[0170] In any of the embodiments disclosed herein, the container 140 may include one or more flexible stiffening elements to maintain the structural form of the container. At least one of the first portion 110 or the second portion 130 may include one or more frameworks to support the configuration of at least the first portion or the second portion. Flexible stiffening elements may be used as frameworks. For example, as shown in FIG. 12 , stiffening elements 190 may be provided as rib liners extending across various portions of the surgical drape 100 and the container 140. Structural reinforcement may be advantageous for extending the life of the container and surgical drape for multiple uses / patient encounters. Structural reinforcement may also be advantageous for multiple uses / patient encounters, such as for fluid management during long surgical procedures involving significant fluid management.

[0171] In some cases, the container 140 may include structures for fluid flow management. The container 140 may include an integrated perforated tubing matrix 200 to maintain fluid flow and air displacement, as shown in FIG. 13, for example. The perforated tubing matrix 200 may be connected to drain / suction ports located at the holes 142 or exit ports 144 of the container 140. The perforated tubing matrix may include one or more tubes 202 that serve as fluid paths or channels. Fluid paths or channels may be provided adjacent to the exit ports 144 to provide unblocking caused by the escape drape. The tubes may be interconnected or may cross each other. Each tube 202 may include multiple perforations 204. The perforations may be provided in a manner that supports air displacement from the tubes and prevents blockage within the matrix. The fluid channels may extend any length along multiple surfaces of the drape 100 beneath the filter screen. For example, multiple fluid channels may extend from about 5 cm to about 40 cm above the walls of the container 140 and below the screen 148. The container can be designed to ensure sufficient suction of fluid from the container by (1) providing an unblockable passageway for suction to act on the fluid or (2) providing a mechanism to prevent material from folding over the vacuum port and blocking it. In some alternative embodiments, the container may include a rolled-up tube-like area 210, as shown, for example, in FIG. 14. The rolled-up tube-like area 210 may be formed from rolled-up drape material and may be connected to an evacuation / suction port to maintain fluid flow and air displacement, similar to the embodiment of FIG. 13.

[0172] In some cases, the container 140 may include a flap to prevent splashing to a user (e.g., a physician). FIG. 15 shows an example of a container 140 including a flap 220. In some cases, the flap may be deployable. The container may be configured with an inner sterile portion and an outer non-sterile portion to protect the physician from splashing. The flap may include a non-sterile portion that extends outside the surgical drape. In some cases, the flap 220 may have a self-supporting semi-cylindrical form. In some cases, one or more stiffening elements 190 can be used to support the structural configuration of the container and / or the flap. In some embodiments, one or more of the stiffening elements 190 may be adjustable in position to prevent splashing to the physician, for example, by raising the flap higher.

[0173] The stiffening elements 190 can extend transversely to one another. For example, the stiffening elements 190 may extend circumferentially and longitudinally along the container 140. The stiffening elements may comprise a bendable material, such as, for example, a thin wire or any stiffening structure or element as described herein.

[0174] In some cases, the container 140 may include one or more ports 230 for receiving fluid from an irrigation or suction pump or from a drain line above or below the screen 148. Figure 16 shows an example of a port 230, according to some embodiments. The port may include an opening, aperture, fenestration, connecting feature, sealing flange, and the like.

[0175] In some embodiments, the container 140 may include one or more extruded portions extending therefrom. One or more of the extruded portions may have a "tent" shape. Referring to FIG. 17 , the extruded portions may help define an inner sterile surface 242 and an outer non-sterile surface 244. The outer non-sterile surface 244 may provide a workspace for placement of a support structure comprising a surgical arm (e.g., articulating arm 14). The outer non-sterile surface allows an ungloved hand to access the sterile space defined within the inner sterile surface 242 for manipulation of the transrectal device.

[0176] In some embodiments, the container may include a removable screen 148, as shown in FIG. 18 , for example. The screen may be removably coupled to the interior lower portion of the container 140. The screen may be removed (252) from the container and folded (254) and sealed (256) for collection and transport of tissue or solid samples (for subsequent analysis or processing). The screen may include holes sized and shaped to allow capture of clots or intact tissue. The screen may include a material that is impermeable to fluids provided along the edges or sides of the screen. In some cases, the screen may include a closure element to secure the sample for storage or transport (allowing the screen to be sealed (256)). The closure element may include a zipper, Ziploc®, adhesive seal, drawstring, clip, or elastic or conformable wire. In some cases, the screen may include a light-transmitting region compatible with imaging modalities for tissue analysis. The screen may be removable from the container along an edge or side of the screen to allow visualization through the translucent region. In some cases, the screen may include an area 258 for displaying information about the patient. Area 258 may be configured to receive preprinted labeling thereon containing information about the patient. Additionally, or optionally, area 258 may be configured to allow a user to write thereon. In some cases, area 258 may include multiple subareas for displaying preprinted information or clinician notes.

[0177] 19, the screen can be configured to fold with the collapse of the container 240. The folding of the screen can be configured to allow air flow to the exhaust / suction port. The screen can be configured to fold in an interleaved manner.

[0178] 20, canopy portion 111 may be designed to conduct fluid to flow downward (260) toward container 140 when the canopy portion is in the inverted configuration. The inverted configuration can prevent fluid from building up or pooling on canopy portion 111 instead of flowing into container 140. The inverted configuration may include one or more sloped surfaces that assist in fluid flowing downward toward the container. Canopy portion 111 may be shaped and / or sized so that the canopy portion does not sag and collects fluid under the weight of the fluid (262).

[0179] In some embodiments, the surgical drape 100 may include one or more indicia as described herein. The indicia may include instructions for using the drape and information regarding one or more of the following: (a) the location of one or more access port holes, (b) the location of one or more perforations, (c) the location of one or more attachment points, (d) the area from which a section of the drape may be removed, (e) placement of the drape on the patient, (f) the location of the drape relative to the operating table, (g) attachment of the drape to the operating table, (h) the location of the drape relative to one or more support structures proximal to the operating table, or (i) attachment of the drape to one or more support structures.

[0180] In some embodiments, surgical drape 100 may include excess material in at least first portion 110 or second portion 130 to allow the non-sterile hands of a user (e.g., a physician) from a non-sterile workspace outside the drape to access and manipulate probe 10 or surgical arm 14 carrying a transrectal device without contaminating the sterile field directly beneath the drape. Canopy portion 111 can be configured to allow a user to manipulate surgical arm 14 supporting a transrectal device.

[0181] FIG. 21 illustrates a surgical drape 100 with one or more markings. The markings may include, for example, a first marking 550, a second marking 552, and a third marking 554. Additional or fewer markings may be provided on the drape 100. The markings may include any of the markings described herein. The markings may be affixed to the drape to identify features of interest on the drape, such as access port holes, perforations, attachment points, areas of the drape that can be removed in sections, placement of the drape on the patient, location of the drape relative to the patient and operating table, location of the drape relative to a support structure, and attachment of the drape to a support structure. One or more markings may include instructions for use of the drape 100, which can be attached to the drape or provided separately. The instructions can be affixed to the drape on the sterile side of the drape to maintain sterility while the one or more instructions are being viewed by a user. The one or more instructions may include an arrow or other indicia to identify a portion of the drape that may be of interest to the user. For example, an arrow or circle may identify an opening on the drape through which the patient's penis is passed from the non-sterile side to the sterile side of the drape. One or more perforations may be identified using indicia associated with the markings to identify the perforations.

[0182] 22A illustrates a method 300 for thermoforming a cover 100 as described herein using a mold 310 and a sheet material 320. The mold may include a receptacle-forming portion 312 with a curved surface, such as a concave surface, for contacting the sheet material 320 to define the receptacle portion 140 of the drape 100. The mold may include a canopy-forming portion 314 with a curved surface, such as a convex surface, for contacting the sheet material 320. The canopy-forming portion may include an inverted portion with an opposite curvature to facilitate drainage as described herein, e.g., an inverted portion adjacent to, near, or within a protrusion of the canopy-forming portion 314. The mold may include a torso-forming portion 316 to define the torso portion of the drape. The mold may include additional structure to accommodate a patient positioned in stirrups for a urological procedure as described herein, e.g., structure to accommodate a patient's bent legs.

[0183] 22B shows the surgical drape 100 being thermoformed over a mold 310 to define a three-dimensional shape profile of the thermoformed surgical drape 330. The thermoformed surgical drape 330 may comprise any of the structures of the surgical drape 100 as described herein. For example, the thermoformed drape 330 may comprise a canopy portion 140 as described herein, a first portion 110 comprising a canopy portion as described herein, and a second portion 130 comprising a torso portion as described herein.

[0184] The thermoformed drape 330 may include one or more stiffening structures as described herein, for example, a stiffening structure sandwiched between multiple layers of thermoformed sheet material. The stiffening structure can be placed on a first thermoformed layer of the drape, and a second layer can be placed over the stiffening structure to sandwich the stiffening structure between the layers, and the layers can be bonded together as part of the thermoforming process. Alternatively, or in combination, an actuator can be sandwiched between the thermoformed layers of the drape to automatically expand and extend the drape from a compact packaged configuration for sterile storage to an expanded and extended configuration for use on a patient. The sheet material may include any biocompatible barrier material that is impermeable to bodily fluids and can be thermoformed on a mold, as would be understood by one of ordinary skill in the art.

[0185] The method 300 for thermoforming the drape 100 may include one or more steps, such as: 1) receiving a sheet material for thermoforming a mold; 2) fabricating a mold with a three-dimensional shape profile; placing the sheet material on the mold; thermoforming the sheet material to the shape of the mold; placing appropriate structures, e.g., stiffening structures, on the thermoformed sheet of material in the appropriate locations and orientations; thermoforming the second sheet of material on the mold to join the first sheet to the second sheet with the stiffening structures therebetween; removing the thermoformed surgical drape 330 from the mold 310; placing the thermoformed surgical drape in a package or wrapping the thermoformed drape in a package portion of the drape in a compact storage configuration; and sterilizing the thermoformed drape.

[0186] Although a method 300 for thermoforming a surgical drape is described herein according to certain embodiments, those skilled in the art will recognize many variations and adaptations. For example, some of the steps may be eliminated or repeated, and steps may be performed in a different order.

[0187] 23A illustrates a user manipulating a transrectal device through the canopy portion 111 of the surgical drape 100 and the corresponding first position 351 of an engagement portion 352 of a proximal portion 350 of a transrectal device comprising a probe 10 as described herein. The engagement portion of the transrectal device may comprise a portion of an actuator 117 as described herein, such as a knob of the actuator. The knob may include a portion of the actuator 117 and may comprise the engagement portion 352 of the transrectal device. The engagement portion 354 of the canopy portion 111 is positioned between the engagement portion 352 of the proximal portion 350 of the transrectal device and an engagement portion 355 of a user's hand, such as the user's finger or thumb. The engagement portion 355 of the user's hand is coupled to the canopy engagement portion 354, and the drape canopy engagement portion 354 is positioned between the engagement portion 355 of the user's hand and the engagement portion 352 of the proximal portion 350 of the transrectal device. The bond allows the canopy to be moved manually such that the proximal portion of the transrectal device feels free to move in the user's hand and the canopy portion has low resistance to movement so that the proximal portion of the transrectal device is positioned within the canopy.

[0188] 23B shows a user manipulating the proximal portion 350 of the transrectal device of FIG. 23A and a corresponding second position of the proximal portion of the transrectal device. The engagement portion 352 of the proximal portion of the transrectal device has been moved to a second position 353 with an engagement portion 355 of the user's hand and an engagement portion 354 of the canopy portion 111. In the second position 353, the canopy has been moved from the first position 351 to the second position 353 with a substantially imperceptible force. The movement of the canopy typically provides resistance to movement less than the amount of force required to move the proximal portion 350 of the transrectal device. The amount of force to move the engaged canopy portion can be less than one-tenth (1 / 10), for example, less than one-hundredth (1 / 100) of the amount of force used to move the engagement portion 352 of the proximal portion of the transrectal device.

[0189] 23C shows the return of the canopy portion engaging portion 354 toward the engaging portion's first position 351 as shown in FIG. 23A. This return of the canopy portion engaging portion allows the user to release the proximal portion of the transrectal device and engage the proximal portion of the transrectal device at a new location 356, allowing the user to again move the proximal portion of the transrectal device while encountering a substantially imperceptible amount of resistance from the canopy portion engaging portion as described herein. The amount of return can be a distance in the range of about 1 mm to about 100 mm, for example, in the range of about 1 mm to about 25 mm.

[0190] The proximal portion 350 of the transrectal device may comprise any proximal portion of a transrectal device as described herein. In some embodiments, the proximal portion of the transrectal device comprises a knob of the transrectal device coupled to the probe to enable movement of the probe of the transrectal device. For example, the probe of the transrectal device can be mounted on a carriage coupled to the knob such that the probe can be advanced distally and retracted proximally with rotation of the knob. In some embodiments, the transrectal device comprises an ultrasound imaging probe as described in PCT Application No. PCT / US2013 / 028441, filed February 28, 2013, entitled "AUTOMATED IMAGE-GUIDED TISSUE RESECTION AND TREATMENT," published as WO / 2013 / 130895 (the entire disclosure of which is incorporated herein by reference). A transrectal ultrasound image can be shown on a display visible to the user such that the transrectal ultrasound probe can be adjusted through the canopy portion by return of the engaged canopy portion as described herein. The transrectal device may include an input / output ("I / O") device as described herein to enable computer control of the position of the transrectal device, and the engagement portion of the canopy can be returned as described herein to facilitate movement of the engagement portion of a user's hand and interaction with the I / O device.

[0191] The substantially imperceptible resistance to force provided by canopy portion 111 as engagement portion 354 moves from first position 351 to second position 353 stores potential energy in the canopy portion, and in some embodiments, additional portions of drape 100. This potential energy is at least partially released when engagement portion 354 of canopy 111 is released by the user's hand and engagement portion 354 moves from second position 353 back toward first position 351.

[0192] FIG. 24A shows the total volume of canopy portion 111 in the extended configuration. In the extended configuration, the canopy sheet is stretched to substantially eliminate flexures and folds. While this can be achieved in many ways, in some embodiments, the lower periphery of canopy portion 111 is supported and the canopy is inflated with a gas, such as air, to extend the canopy into the extended configuration and determine the canopy volume. Canopy portion 111 may have a length L, a width W, and a height H, for embodiments in which the canopy comprises a rectangular protruding portion. Each of these dimensions may be defined by the distance between corresponding corners of the canopy portion. The total volume of the canopy portion corresponds to the length, width, and height and may be calculated using known formulas. In some embodiments, the protruding canopy may have one or more generally straight sides, for example, a partially trapezoidal shape. In some embodiments, the canopy portion comprises a curved surface sized and shaped to receive at least a proximal portion of the transrectal device. The curved surface when extended substantially without flexing or folding defines the volume of the canopy portion. Canopy portion 111 may, for example, comprise a combination of generally flat and curved surfaces. In some embodiments, the lower perimeter of the canopy portion is supported and the canopy portion is inflated with gas, extending the canopy portion to a fully extended configuration to determine the total volume. The amount of gas, such as air, within a fully expanded canopy portion can be measured by contracting the canopy portion to a fully contracted, compact configuration and measuring the amount of gas released. The amount of gas released may be measured by any number of methods known to those skilled in the art.

[0193] FIG. 24B illustrates the reduced volume of the canopy portion 111 of FIG. 24A in a partially collapsed, freestanding configuration. The height H is reduced in the freestanding configuration, and the barrier sheet material may include folds, e.g., to reduce the height H by at least about 10%. The length L and width W, defined by the distance between the corners of the canopy, may also be similarly reduced, e.g., by at least 10%. In some embodiments, the volume of the canopy decreases by an amount in the range of about 10% to 90% between the fully extended configuration and the partially collapsed, freestanding configuration. The canopy may include at least some weight such that the volume of the canopy is reduced in the partially collapsed, freestanding configuration compared to the volume of the canopy in the fully extended, extended configuration. The weight and stiffness of the canopy's barrier material can be configured to provide for partial collapse of the canopy. A heavier (e.g., thicker) and less stiff barrier material will collapse more than a lighter (e.g., thinner) barrier material with similar stiffness. A stiffer barrier material may collapse less.

[0194] The canopy's lower perimeter is supported, and the volume of the partially collapsed canopy can be determined, for example, based on the amount of gas released when the canopy is compressed from a free-standing, partially collapsed configuration to a fully collapsed configuration. In some embodiments, the canopy barrier material prevents air from flowing out of the canopy. If present, the canopy seal may comprise an airtight seal to maintain a sterile field above the canopy. The canopy's 111 barrier material may have a Young's modulus, thickness, and density configured to provide for partial collapse of the canopy in a free-standing configuration as described herein.

[0195] The amount of recoil of the canopy portion as described herein can be related to the Young's modulus, thickness, density of the barrier material, and the volume of the total volume of the canopy portion, which is related to the amount of movement of the proximal portion of the transrectal device.

[0206] In some embodiments, the surgical drape is in a compact configuration when the surgical drape is not in use prior to deployment, and is deployed to an extended configuration prior to or during use of the surgical drape for a surgical procedure on a patient.

[0207] 26 shows an opening sized to receive a surgical urology probe and perforations 132 extending in a first direction corresponding to the inferior and superior directions of the patient and perforations 450 extending in a second direction transverse to the first direction to allow surgical drapes to be removed around a base 457 of the tensioning device coupled to the patient using a catheter extending along the patient's urethra. An example of the base and tensioning device is disclosed in US Pat. No. 6,932,499, filed March 17, 2017, entitled "MINIMALLY INVASIVE METHODS and systems for hemostasis in a bleeding closed tissue volume," and published as WO / 2017 / 161331 (the entire disclosure of which is incorporated herein by reference). The base may comprise a maximum dimension 454 across the base. The perforations 450 extending in the second direction may extend a distance 452 greater than the maximum dimension 454 across the base to facilitate removal of the surgical drape when the base and tensioning device are coupled to a patient. The maximum dimension across the base may be in the range of about 2.5 cm to about 30 cm, e.g., in the range of about 3 cm to about 20 cm. The distance 452 may comprise a distance in the range of about 2.5 cm to about 60 cm, e.g., in the range of about 3 cm to about 40 cm.

[0208] Although perforations are referenced, the surgical drape can be configured in many ways similar to perforations 132 and 450. In some embodiments, the second portion comprising the torso portion includes a weakened material extending along an inferior-superior direction of the patient, e.g., in a direction corresponding to a direction along the midline. The second portion can be configured to aid in removal of the surgical drape by allowing the second portion to separate along the weakened material. In some embodiments, the weakened material includes one or more of perforations, thinned material relative to adjacent non-weakened material, thermally or chemically weakened material, or stressed material along the midline or at any angle or offset relative to the midline to generally extend along the patient's generally inferior or superior lateral side. In some embodiments, a second weakened material extends in a second direction transverse to the midline to facilitate removal of the surgical drape around the base of a traction device coupled to the patient using a catheter extending along the patient's urethra. The second weakened material extending in the second direction may be weakened in the same way as the weakened material extending in the first direction, and may, for example, comprise perforations extending in the second direction.

[0209] In some embodiments, the perforations allow for insertion or access of a catheter inserted into the patient's urethra. The catheter may comprise, for example, a suprapubic catheter for draining urine from the patient's bladder.

[0210] FIG. 27 shows the receptacle portion 140 of the surgical drape 100 with a porous structure, such as a screen 148, upstream of the suction port 462. The porous structure located upstream of the suction port 462 may comprise any porous structure as described herein, such as one or more of a tube with holes on the outer wall, a screen, a mesh, a fabric, a grid, a plurality of openings formed in a sheet of material, an open-cell foam, a sponge, a screen, a perforated tubing matrix, a fabric, a sintered material, or particles held together to define a channel. The mesh may comprise, for example, a fine mesh. The porous structure, such as the screen 148, located upstream of the suction port can be coupled to the inner wall of the receptacle portion 140 to direct fluid entering the receptacle portion 140 through the porous structure. The suction port can be connected to a source of suction, such as a surgical suction pump, and a tube can be coupled to the suction port and the source of suction. The porous structure, such as the screen 148, can filter out particles comprising blood clots and ablated tissue to prevent blockage of the suction port 462. In some embodiments, the porous structure comprises channels having a maximum cross-sectional size that is equal to or less than the minimum inner cross-sectional size (e.g., minimum diameter) of the suction port 462 to ensure passage of clots or tissue passed by the porous structure through the suction port. The porous structure may comprise a surface area for receiving surgical fluids, clots, and tissue.

[0211] The container portion 140 may include a fluid inlet 460 for receiving flowable material from a surgical procedure, such as surgical fluid comprising tissue and clots from an ablation procedure. The ablation may comprise a water jet ablation procedure performed using an ablation probe such as that described in PCT Application No. PCT / US2013 / 028441, filed February 28, 2013, and entitled "AUTOMATED IMAGE-GUIDED TISSUE RESECTION AND TREATMENT" (previously incorporated by reference). Fluid from the surgical probe can be coupled to the inlet with a tube so that the ablated prostate tissue material can be collected on the porous structure and used for subsequent analysis.

[0212] In some embodiments, the receiving surface area of ​​the porous structure comprises a surface area greater than the minimum inner cross-sectional size of the suction port to provide additional channels in the porous structure for the passage of surgical fluids when solid matter, such as blood clots and tissue, is deposited on the porous structure.

[0213] The porous structure may include channels extending through its thickness that are sized and shaped to collect tissue from the surgical procedure for subsequent analysis. The channels can be sized to an appropriate size for prostate cells or less, e.g., about 5 microns (μm) or less. The channels of the porous structure may have a maximum cross-sectional size, e.g., in the range of about 0.1 microns to about 5 microns, to capture individual prostate cells. Alternatively, the channels of the porous structure may have a larger cross-sectional size, e.g., in the range of about 5 μm to about 1 mm, to capture prostate tissue, including cells and clots, received from the inlet 460.

[0214] In some embodiments, the porous structure 148 and suction port 462 are configured to allow a quantity of fluid 464 to accumulate within the container. The porous structure can reduce the amount of fluid that accumulates within the container portion 140 compared to fluid accumulation without the porous structure. The surface area and size of the channels in the porous structure can be configured to reduce the amount of fluid that accumulates between the porous structure and the opening to the suction port on the inside of the container when the suction port is coupled to a suction source. The amount of fluid that accumulates using the porous structure on the lower end of the container is approximately 0.05 cm. 3 ~about 500cm 3 Within the range of, for example, about 0.05 cm 3 ~Approx. 100cm 3 In some embodiments, the porous structure can be separated from the suction port by a gap extending therebetween, and the amount of fluid that accumulates between the porous structure and the opening to the suction port can be in the range of, for example, about 0.05 cm. 3 ~Approx. 100cm 3 may be in a similar range.

[0215] 28 shows a container 510 with a viewing window 514 sized to receive a porous structure, such as screen 148, on which a substance from a patient is supported. The viewing window may include an optically transparent material configured to allow viewing of the substance from the patient using, for example, a high-resolution microscope. The container 510 may comprise a sealed container that can be sealed with the porous structure and the patient's substance placed thereon. The container may include a barrier material configured to prevent release of the substance from the patient.

[0216] FIG. 29 shows an image of a surgical drape 100 used to perform experimental testing. The inventors performed several experiments to determine advantageous structures, elements, and portions of a drape as described herein, as well as other elements. The surgical drape shown in FIG. 29 includes many of the elements and structures shown and described above with reference to FIG. 1B. This testing was used to determine the appropriate shape and structure and material properties of the drape to provide the beneficial functions and structures as described herein, such as fluid management, stiffening structure and dimensions of the canopy and container, canopy return, and dimensions and material properties of the porous structure, as described herein.

[0217] Those skilled in the art will understand in light of this disclosure that a surgical drape comprises a sterile side generally facing away from the patient and a non-sterile side generally facing toward the patient to provide a sterile barrier between the patient and the sterile side of the drape when placed on the patient. Alternatively, or in combination, the surgical drape may be configured to cover the patient's feet or legs, e.g., a second portion comprising a torso portion as described herein may extend to cover one or more of the patient's feet or legs.

[0218] In some embodiments, the drape user places the handpiece and / or resectoscope on top of the drape over the patient's stomach, and the drape may include fasteners, such as straps or Velcro® or tethers or tape sections, configured to allow the user to place the handpiece away from or on the patient's stomach. Alternatively, or in combination, the patient drape may include an adhesive material for adhering and bonding to the handpiece and / or resectoscope to limit movement of surgical instruments. The adhesive can be covered with a peel or other material so that the adhesive material is not exposed until the peel is removed from the adhesive surface by a user, such as a physician or nursing assistant. Securing the handpiece and / or resectoscope on the drape over the stomach can prevent the instrument from slipping into a fluid container such as those described herein, which would not be ideal because the container may contain fluids and / or packets / gauze from earlier stages of the surgical procedure.

[0219] In some embodiments, the surgical drape includes fasteners, such as one or more sections of tape or Velcro®, on one or more sides of the patient's leg for wire and cable and tubing management, which can be used to bind them together.

[0220] In some embodiments, a surgical drape as described herein comprises a packaging enclosure for storing the surgical drape, or a portion thereof, when the surgical drape has an initial compact configuration prior to expansion to an extended configuration, e.g., in its original state prior to use. The packaging portion comprises an extended portion of the surgical drape configured to cover the drape in the compact configuration, e.g., a lower non-sterile side of the portion of the drape may be folded to expose the non-sterile external environment. An inner sterile side of the folded portion of the drape corresponding to the upper sterile side of the drape can be folded into the remainder of the drape when the drape has the compact configuration prior to expansion to an extended configuration as described herein.

[0221] Although alternatives are referenced in this disclosure, one skilled in the art will recognize that these alternatives may be combined in accordance with the teachings of this disclosure.

[0222] While preferred embodiments of the present invention have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention.
