Description

[Technical Field]

[0001] The present disclosure relates generally to drainage systems for use in medical procedures, particularly those in which lithotomy stirrups are employed. [Background technology]

[0002] During surgical procedures, more specifically urological or gynecological surgical procedures, clinicians may use fluids, such as sterile saline, to irrigate the surgical site. To ensure patient safety, it is necessary to collect such fluids and record the amount used during the procedure. If such fluids pool or collect on the floor, they can pose a hazard to clinicians and members of the surgical team. Often, such procedures are performed with the patient in a supine position, with the patient's legs elevated and away from the surgical site near the perineum. To ensure access to the surgical site, the patient's legs may be placed in lithotomy stirrups to optimize access to the surgical site. These stirrups are attached to the operating table by clamps attached to the distal ends of the table side rails.

[0003] Drainage bags, more specifically, urinary drainage bags, are known for collecting fluids during surgical procedures. Reusable flexible band systems exist that connect to reusable clamps mounted to the distal end of the side rails of an operating table. The reusable flexible bands allow for the attachment of disposable drainage bags to collect fluids during procedures. Other systems consist of disposable drainage bags attached to flexible bands, which are connected to the operating table by reusable rail-mounted clamps. These reusable clamps are attached to the distal end of the operating table side rails. Disposable drainage bag systems also exist in the art, which consist of disposable drainage bags attached to flexible bands, which are attached to disposable clamps that connect to the distal end of the operating table side rails. These disposable clamps fit only one size of operating table rail. An advantage of the completely disposable drainage bag systems described above is that the clamps do not need to be cleaned and sterilized after each procedure and then stored for eventual reuse.

[0004] However, the clamps of such systems, and all conventional clamps used in the current state of the art described in this application, occupy a portion of the distal end of the operating table rail. According to current technology, when disposable or reusable clamps of these systems are used with lithotomy stirrups, the clamp that attaches the stirrup must move proximally toward the patient's head because the disposable clamp is attached to the distal end of the operating table rail. Not attaching the lithotomy stirrup to the distal end of the operating table rail would prevent the locking joint, which is proximal to the stirrup, from being placed at the patient's hip joint, as recommended by all stirrup manufacturers.

[0005] If the locking joint proximal to the stirrup is not attached to the patient's hip joint, increased stress on the patient's hip can occur, which can lead to injury or potential post-procedure pain.

[0006] Instruments such as scopes, retractors, and forceps are often used multiple times during procedures, such as those requiring the patient to be placed in the lithotomy position using stirrups. These instruments can be secured to the side rails of the operating table by mounting clamps. Because the distal end of the operating table side rail is occupied by the clamps that secure the stirrups to the operating table, it can be difficult for clinicians to access other instruments if they are operating on the perineum. Summary of the Invention [Means for solving the problem]

[0007] The present disclosure is generally directed to disposable (i.e., they can be discarded after each use) surgical drainage bag systems. In some embodiments, such surgical drainage bag systems can include disposable flexible bands to which disposable clamps, disposable drainage bag drapes are attached, all of which can be discarded after use. This system allows a user to attach the system to a surgical table and then discard the system after each use.

[0008] As described in detail below, a surgical drainage bag system according to the present teachings allows for a stirrup mounting clamp to be positioned on the distal end of a side rail of a surgical table, thereby allowing for safe positioning of the patient. If a stirrup is not used, a surgical drainage bag system according to the present teachings allows for a disposable clamp to be attached onto the distal end of the surgical table rail to secure the disposable drainage bag system.

[0009] Operating table side rails to which accessories, including drainage bag systems, are attached come in a variety of sizes, including different widths and heights, including, but not limited to, US, EU, and UK operating table side rails. With current technology, both the reusable and disposable clamps of conventional drainage bag systems fit only one size of operating table rail. This means that facilities with various tables with multiple rail sizes must maintain multiple conventional types of drainage bag systems, each with a differently sized clamp. The present invention allows one disposable clamp to engage various rail sizes, meaning that hospitals with various tables with different rail sizes only need to procure one type of drainage bag system.

[0010] In many urological and gynecological procedures requiring fluid collection systems, other accessories, instruments, and surgical aids can be attached to the side rails present on most operating and procedure tables via table rail clamps. Lithotomy stirrups are used to elevate and hold the legs away from the surgical site; this is just one example of a commonly used surgical equipment accessory and / or surgical aid. Attaching a lithotomy stirrup to the table side rail via a table rail clamp improves clinician access to the surgical site. These lithotomy stirrups often use a gas-filled cylinder, which provides an upward force that reduces stress or strain on the clinician when elevating and positioning the patient's legs. The gas cylinder is typically attached to a distal attachment point on the stirrup support rod and to a proximal mounting lug on a mounting plate at approximately the same level on the table rail.

[0011] In some embodiments, a surgical drainage bag system according to the present teachings can include a flexible band and a disposable drainage bag drape, along with a disposable clamp (which can be attached to a surgical table side rail), all of which can be disposed of after each use, plus an accessory mounting mechanism that can secure the disposable drainage bag, flexible band, and clamp to equipment or accessories configured to be mounted on a procedure table, such as a procedure or operating table.

[0012] In many embodiments, disposable clamps allow for the accommodation of various sizes of operating table rails, eliminating the need to stock multiple drainage bag systems with differently sized clamps to accommodate these different rail sizes. Accessory mount mechanisms may be attached to specific surgical accessories or instruments used during a medical procedure to secure and use the disposable drainage bag system. Such accessory mounts for disposable drainage bag systems eliminate the need for a rail to mount the drainage bag system when certain surgical accessories are used, thus creating more space at the distal end of the operating table rail. This additional space at the distal end of the operating table rail allows the locking joint proximal to the lithotomy stirrup to be properly attached to the patient's hip joint, which in turn reduces the risk of stress on the patient's hip joint, which may lead to injury during the procedure and / or pain in the patient's lower back after the procedure.

[0013] In embodiments, the disposable drainage bag system may include a disposable drainage bag, a flexible band coupled to and supporting the disposable drainage bag, and a disposable clamp configured to receive a surgical table side rail or an accessory mount arm that may be similar in size to a surgical table side rail.

[0014] The disposable clamp may include a channel for receiving the operating table rail or accessory mount arm and a band-receiving slot on the other side of the disposable clamp, sized to receive a flexible band. In some embodiments, the band-receiving slot may include recesses and / or holes at predetermined locations within the band-receiving slot, which may be sized to receive detents, buttons, ridges, and protrusions that may be formed on the flexible band. In some embodiments, upper and lower ledges may be formed on the disposable clamp body. These ledges may each have stabilizer extensions formed thereon that are substantially rigid and substantially parallel to the lower and upper surfaces of the lower and upper ledges. As used herein, the term "substantially rigid" is defined as deflecting less than 0.10 inches (0.254 cm), and substantially parallel means not deviating more than 10 degrees from a reference plane. In some embodiments, the disposable clamps may be made of a plastic such as polyethylene, polyurethane, polycarbonate, polyethylene terephthalate, or acrylonitrile-butadiene-styrene (ABS).

[0015] In some embodiments, a disposable clamp for coupling a flexible band and a drainage bag to a surgical table side rail or accessory mount arm is disclosed. The disposable clamp may include a rail-receiving channel on one side to receive the surgical table side rail or accessory mount arm. In some embodiments, the rail-receiving channel may be formed by upper and lower ledges of the disposable clamp, while each ledge may have a lip formed on a distal edge of the upper and lower ledges of the disposable clamp. The clamp may have a body including a proximal side in some embodiments. In some embodiments, the proximal side of the clamp may have a notch cut or formed therein. The rail-receiving channel may be shaped and sized to fit over the surgical table rail or accessory mount arm.

[0016] In some embodiments, the upper ledge may have a chase cut into its underside to accommodate differently sized accessory rails, particularly rails that may have a narrower width or greater height than the rail-receiving channel of the disposable clamp. In other embodiments, the upper ledge chase may fit into at least one fin formed on the accessory mount arm, stabilizing the disposable clamp when so mounted. In some embodiments, the lower ledge may be formed to include a threaded hole that can receive a threaded knob that can enter and engage therethrough. In some embodiments, the threaded hole is offset from the center of the clamp body and aligned with the centerline of a chase formed on the underside of the upper ledge of the disposable clamp. In some embodiments, a threaded screw may be engaged through the threaded hole in the lower platform, allowing the operating table rail to be inserted into the upper ledge chase, thus engaging the operating table rail with the upper ledge chase. In some embodiments, the underside of the lip of the upper ledge is lower than a notch cut into the upper ledge of the proximal clamp face that forms one side of the rail-receiving channel. In other embodiments, a threaded screw can be engaged through a threaded hole in the lower platform to engage the clamp with the accessory mount arm. In other embodiments, the upper ledge can be formed to include a threaded hole that can receive a threaded knob that can be engaged therethrough. In some embodiments, the lower ledge can include a distal lip and can also include an extended stabilizer that protrudes from the lower ledge opposite the side of the band-receiving slot of the disposable clamp. In one embodiment, the upper ledge of the clamp can include a lip on its distal side and can also have an engagement surface that is lower than the notch in the proximal clamp wall and can have a stabilizer extension that protrudes from the ledge opposite the band-receiving slot of the disposable clamp.In such embodiments, a lip formed on the upper ledge may project distally and downwardly away from the top surface of the ledge to aid in engagement of an operating table rail or accessory mount arm. In some embodiments, a lip formed on the lower ledge may project distally and upwardly away from the bottom surface of the lower ledge to aid in engagement of an operating table rail or accessory mount arm. In some embodiments, the proximal side of the clamp body with the notch, the upper and lower ledges, the upper and lower edge lips, and the upper and lower stabilizer extensions of the ledges may form a monolithic body formed, for example, from plastic.

[0017] The proximal side of the clamp body with the notch, the underside of the upper ledge, the lip of the upper ledge including the engagement surface and the lower ledge with the lip, and the upper and lower stabilizer extensions of the ledge constitute a rail-receiving channel in which an operating table rail or accessory mount arm can be engaged. In some embodiments, the underside of the upper ledge may have a chase cut into it to accept a rail that is narrower and / or taller than the width of the rail-receiving channel. In other embodiments, the components of the operating table rail-receiving channel may include separate plastic or metal pieces or a combination of metal and plastic parts that can be assembled, for example, by press-fitting, welding, or gluing. In still other embodiments, the disposable clamp body, ledge, lip, and extended stabilizer may be formed of metal.

[0018] The disposable clamps may engage with the operating table rail or accessory mount arm using the clamp rail receiving channel. In some embodiments, the upper portion of the operating table rail is narrower and / or taller than the rail receiving channel and can fit into the upper ledge chase. In other embodiments, the upper chase can fit into a fin formed on the upper surface of the accessory mount arm. A threaded knob can then be inserted into and engaged with the threaded hole in the lower ledge such that the distal portion of the threaded knob in turn engages with the operating table rail or accessory mount arm, thus securing the disposable clamp in place. In other embodiments, the threaded knob can enter and engage through the threaded hole, forcing it against a rail that is narrower and / or taller than the rail engagement channel and engaging the upper ledge chase, thus securing the rail to the disposable clamp.

[0019] In some embodiments, a flexible band receiving slot may be formed on the side of the disposable clamp opposite the rail receiving channel. The flexible band receiving slot may have at least one recess in one embodiment. The at least one recess may have a variety of shapes, including, but not limited to, linear, square, cubic, round, oval, hexagonal, circular, or elliptical, or may be formed in other shapes. In other embodiments, the clamp rail channel may have at least one through-hole. The at least one through-hole may have a variety of shapes, including, but not limited to, linear, square, cubic, round / circular, oval, oval, or hexagonal. In other embodiments, the band receiving slot may have at least two recesses therein, each of which may be the same or different shapes or sizes, including, but not limited to, the following shapes: linear, square, cubic, round / circular, oval, oval, or hexagonal. In other embodiments, the disposable clamp band receiving slot may have at least two through-holes. The at least two through holes may have a variety of shapes, including but not limited to: rectilinear, square, cubic, round / circular, elliptical, oval, or hexagonal.

[0020] In some embodiments, a band-receiving slot may be formed on the clamp side opposite the rail-receiving channel. The band-receiving slot may have at least one recess in one embodiment. The at least one recess may be formed to receive a sawtooth or barbed ridge or protrusion, or other polygonal shape. In other embodiments, the clamp rail channel may have at least one through-hole or recess. The at least one through-hole or recess may be formed to receive a sawtooth or barbed ridge or other polygonal shape. In other embodiments, the clamp band slot may have at least two recesses or through-holes therein, each of which may be the same or different shapes or sizes in any combination capable of receiving a barbed or sawtooth ridge or other polygonal shape. In other embodiments, the at least one through-hole or recess may be formed to receive various shapes, including, but not limited to, a barbed or sawtooth ridge.

[0021] In some embodiments, a band receiving slot may be formed on the clamp side opposite the rail receiving channel. In some embodiments, the band receiving slot may have at least one recess and at least one through-hole. The at least one recess and the at least one through-hole may be formed to receive ridges that are serrated or barbed protrusions, or other shapes and combinations of shapes. The clamp band slot may have at least one recess and at least one through-hole therein, and each of the at least one through-hole or the at least one recess may be the same or different shapes or sizes in any combination that can receive barbed or serrated ridges or shapes in any combination.

[0022] In some embodiments, a surgical drainage bag system may include a disposable drainage drape bag, a flexible band, a disposable clamp, and an accessory mounting mechanism. In some embodiments, the accessory mounting mechanism may be secured to an accessory or other device used in a surgical procedure, particularly a lithotomy stirrup, configured to attach to a procedure or operating table. In one embodiment, the accessory mounting mechanism is disposable after use. In other embodiments, the accessory mounting mechanism may be semi-permanently attached to an accessory or other device configured to attach to a procedure or operating table, particularly a lithotomy stirrup. In one embodiment, the accessory mounting mechanism may be formed or molded from a plastic component. In other embodiments, it may be formed or fabricated from a metal. In yet other embodiments, it may be fabricated or formed from a combination of plastic and metal components. It is contemplated that in some embodiments, the accessory mounting mechanism may be formed as a monolithic component of either plastic or metal. In other embodiments, it may be made from two or more separate pieces of plastic or metal, which may be press-fit using indentations and mating ridges or protrusions, or held together by other mechanical means such as a mounting rod. In some embodiments, the accessory mount mechanism may include a monolithic accessory mount clamp made of plastic or metal and having at least two holes formed in its structure, at least one of the holes being threaded, a separate spacer made of plastic or metal with a through hole, and a mounting rod threaded on one end and having a flat head on the opposite end.

[0023] The accessory mount mechanism, in some embodiments, may include a horseshoe- or "U"-shaped accessory mount clamp with holes formed in two of its arms, a spacer with a through-hole, and a mounting rod with a threaded end and a flat head on the opposite end. In some embodiments, the spacer is "T"-shaped, while in other embodiments, the spacer is formed as a straight block. In still other embodiments, it may be round or semicircular in shape. The accessory mount clamp is shaped and sized to fit snugly and closely around the outer periphery of the stirrup gas cylinder mounting lug of the lithotomy stirrup when the spacer is attached to the accessory clamp. The proximal mounting lug for the gas cylinder varies in size for various stirrup manufacturers. In some embodiments, different sizes of accessory mount clamps and spacers are available to fit snugly and closely around the outer periphery of the various sizes of gas cylinder gas mounting lugs for each stirrup manufacturer.

[0024] In some embodiments, the accessory mount clamp can include an upper arm, a lower arm, and a semicircular portion. The upper arm, lower arm, and semicircular portion of the accessory mount clamp are designed to fit closely and snugly against the outer surface of the stirrup gas cylinder mount lug. In some embodiments, the upper arm, lower arm, and semicircular portion of the accessory mount clamp are formed or molded as a monolithic piece from plastic or formed or fabricated from metal. In still other embodiments, the portions are plastic or metal and press-fit or glued together using indentations with slots that accept barbed or serrated protrusions or ridges. In one embodiment, the upper arm is formed with a threaded hole capable of accepting a threaded rod, while the lower arm is formed with a hole that faces the corresponding hole in the upper arm. In other embodiments, the lower arm has a threaded hole and the upper arm has a non-threaded hole directly opposite the hole in the upper arm. In some embodiments, a mount arm is formed, centered on the distal edge of the semicircular portion, and projects outward from the portion at a substantially right angle. The term substantially right angle is defined as 90 degrees plus or minus 5 degrees. The mount arm is the size of an operating table rail. In some embodiments, a fin sized to fit over the upper ledge chase of a disposable clamp is formed on the upper surface of the accessory mount arm. A spacer, formed or molded from plastic or metal, is approximately equal in length to twice the inner diameter of the semicircular portion of the accessory mount clamp in some embodiments and is fabricated or formed from plastic or metal. In some embodiments, the spacer has a through hole extending from its top to its bottom. The spacer fits over a portion of the surface of the stirrup gas spring mount lug and through holes formed in the spacer that align with holes formed in the upper and lower arms of the accessory mount clamp.In one embodiment, a mounting rod (machined or formed from metal, plastic, or a suitable material) with one threaded end and a flat head on the opposite end is threaded through the lower arm of the accessory mount clamp and into the through-hole in the spacer. The threaded end of the rod, in one embodiment, is designed to fit and engage with a threaded hole in the upper arm of the accessory mount clamp.

[0025] In some embodiments, a spacer rod (machined or formed from metal) with one threaded end and a flat head on the opposite end is threaded through a hole in the upper arm of the accessory mount clamp and into the through-hole of the spacer. The threaded end of the rod enters and engages a threaded hole in the lower arm of the accessory mount clamp, thereby securing the accessory mount clamp to the surface of the stirrup gas cylinder mount lug. In some embodiments, the spacer is rectangular in shape. In other embodiments, it is "T" shaped with a flange. In some embodiments, the "T" flange has a side with a semicircular notch, while in other embodiments, the "T" flange has a linear notch. In other embodiments, the spacer is circular, oval, or semicircular, and may have flanges of various shapes, including, but not limited to, square, circular, or hexagonal. The spacer is secured to the upper and lower arms of the accessory mount clamp by the threaded rod and fits snugly against the surface of the stirrup gas cylinder mount lug.

[0026] In one embodiment, it is contemplated that the mount arm, which includes a fin on its upper surface that protrudes distally from the semicircular portion of the accessory mount clamp, is formed or molded as part of the monolithic plastic or metal structure of the accessory mount clamp. In other embodiments, the mount arm and fin may be formed from a separate piece of plastic or metal and connected to the accessory mount clamp by means of a press-fit connection or adhesive / welding or any combination thereof. In some embodiments, the mount arm can be sized to match the size of the operating table rail.

[0027] In some embodiments, the accessory mount clamp may be attached to the stirrup gas cylinder mount lug by fitting the upper arm, lower arm, and semicircular portion of the accessory mount clamp around the surface(s) of the stirrup gas cylinder mount lug. A mounting rod can be threaded through the upper arm of the accessory mount clamp and into the through-hole of the spacer, engaging the threaded hole in the lower arm of the accessory mount clamp, thus securing the spacer to the accessory mount clamp, which in turn secures the accessory mount clamp to the stirrup gas cylinder mount lug. The side of the disposable clamp with the rail-receiving channel can slide onto the fin-equipped mount arm of the accessory mount clamp, and the upper ledge chase fits around the mount arm fin. The upper and lower stabilizer extension arms of the disposable rail clamp and the fit of the mount arm fin to the upper ledge chase help stabilize the disposable clamp against any twisting forces. In some embodiments, the threaded knob of the disposable clamp can be engaged with the threaded hole in the lower ledge of the disposable clamp to secure it to the mount arm of the accessory mount clamp. The flexible band with the attached drainage bag drape can then be secured to the disposable clamp.

[0028] The accessory mount mechanism, in some embodiments, may include a horseshoe- or "u"-shaped accessory mount clamp with upper, lower, and curved arms with holes formed in the upper and lower arms, a spacer with a through-hole, and a mounting rod with a threaded end and a flat head on the opposite end. In some embodiments, the spacer is "t"-shaped, while in other embodiments, the spacer is shaped as a block. In still other embodiments, it may be round or semicircular in shape. In some embodiments, the spacer may have a straight or circular flange, and the flange may have a semicircular or straight notch. The accessory mount clamp is sized to fit snugly and closely around the surface(s) of a protrusion or extension of a surgical accessory or surgical instrument, and in some embodiments, such extension has a diameter of about 0.25 to about 4 inches (about 0.635 to about 10.16 cm) (for circular protrusions) or a longest cross-sectional width (for straight protrusions) of about 0.25 to about 4 inches (about 0.635 to about 10.16 cm), and the protrusion extends from the surface of the instrument or accessory for a length of 1 / 2 inch to 8 inches (about 1.27 to about 20.32 cm). In some embodiments, when attached to the mounting accessory clamp, the spacer fits snugly around the proximal surface of a surgical accessory or instrument protrusion having a diameter between 0.25 and 4 inches (0.635 and 10.16 cm) or a cross-sectional width between about 0.25 and about 4 inches (0.635 and 10.16 cm) and extending outward from the surface of the accessory or instrument for a length of up to 8 inches (20.32 cm).

[0029] In other embodiments, there may be a mounting lug or protrusion formed on the operating table accessory rail clamp used to attach the accessory to the operating table. The rail clamp mounting lug may be sized so that the accessory mount clamp can fit snugly and closely around the outer periphery of the lug. In some embodiments, the accessory mount clamp may be attached to the rail clamp mounting lug of the operating table rail accessory clamp by fitting the upper arm, lower arm, and semicircular portion of the accessory mount clamp around the surface(s) of the stirrup gas cylinder mounting lug. A mounting rod may be threaded through the upper arm of the accessory mount clamp and into the through-hole of the spacer, engaging the threaded hole in the lower arm of the accessory mount clamp, thus securing the spacer to the accessory mount clamp, which in turn secures the accessory mount clamp to the operating table rail clamp mounting lug. The side of the disposable clamp with the rail-receiving channel can slide onto the fin-equipped mounting arm of the accessory mount clamp, and the upper ledge chase fits around the mounting arm fin. The upper and lower stabilizer extension arms of the disposable rail clamp and the engagement of the mounting arm fins with the upper ledge chase help stabilize the disposable clamp against any twisting forces. In some embodiments, a threaded knob on the disposable clamp can be engaged with a threaded hole in the lower ledge of the disposable clamp to secure it to the mounting arm of the accessory mounting clamp. A flexible band with an attached drainage bag drape can then be secured to the disposable clamp.

[0030] In some embodiments, the operating table rail clamp may have a mounting arm with fins formed on its distal end. The side of the disposable clamp with the rail-receiving channel can slide onto the finned mounting arm of the accessory mounting arm, and the upper ledge chase fits around the mounting arm fins. The upper and lower stabilizer extension arms of the disposable rail clamp and the fit of the mounting arm fins to the upper ledge chase help stabilize the disposable clamp against any twisting forces. In some embodiments, a threaded knob on the disposable clamp can engage a threaded hole in the lower ledge of the disposable clamp, securing it to the mounting arm of the accessory mounting clamp. A flexible band with an attached drainage bag drape can then be secured to the disposable clamp.

[0031] In some embodiments, the operating table accessory rail clamp may have a mount arm with fins formed within the distally protruding mount arm. In other embodiments, the finned mount arm may be attached to the operating table accessory rail clamp via a mechanical attachment. The side of the disposable clamp with the rail-receiving channel can slide onto the finned mount arm of the accessory mount arm, and the upper ledge chase fits around the mount arm fins. The upper and lower stabilizer extension arms of the disposable rail clamp and the fit of the mount arm fins to the upper ledge chase help stabilize the disposable clamp against any twisting forces. In some embodiments, the threaded knob of the disposable clamp can engage a threaded hole in the lower ledge of the disposable clamp to secure it to the mount arm of the accessory mount clamp. A flexible band with an attached drainage bag drape can then be secured to the disposable clamp.

[0032] The flexible band may be formed from commonly available plastic or other suitable materials. In one embodiment, the flexible band may have at least one protrusion formed on each of its ends. The at least one protrusion may have at least one protrusion or ridge, which may be formed in different shapes. In some embodiments, the at least one ridge or ridge on the protrusion may be, but is not limited to, the following shapes: linear, square, cubic, round, oval, elliptical, hexagonal, or circular, in any combination, and sized to fit into at least one recess in the flexible band receiving slot. In other embodiments, the shape of the at least one ridge or ridge on the at least one protrusion may be sawtooth or barbed, in any combination, and sized to fit into at least one recess in the flexible band receiving slot. In some embodiments, the flexible band may have at least one notch cut into its end, forming at least one protrusion with at least one ridge on the protrusion of the flexible band.

[0033] The flexible band may be formed from commonly available plastic or other suitable materials. In some embodiments, the flexible band may have at least two protrusions formed on each end thereof. Each of the at least two protrusions may have at least one protrusion or ridge, which may be formed in a different shape. In some embodiments, the at least one ridge or ridge formed on the at least two protrusions may be, but is not limited to, the following shapes: linear, square, cubic, round, oval, elliptical, hexagonal, or circular, in any combination, and sized to fit into at least two recesses in the flexible band receiving slot. In other embodiments, the shape of at least one ridge or ridge on the at least two protrusions may be sawtooth or barbed, in any combination, and sized to fit into at least two recesses in the flexible band receiving slot. In some embodiments, the flexible band may have at least one notch cut into its end, forming at least two protrusions with at least one ridge on at least two protrusions of the flexible band.

[0034] In some embodiments, the distance between at least one ridge on a different projection of the flexible band is slightly greater than the height of the disposable band receiving slot formed in the side of the disposable clamp. As used herein, the term "slightly greater" is defined as being greater by about 0.1 to about 0.15 inches (about 0.254 to about 0.381 cm). When the flexible band is inserted into the disposable band receiving slot, the at least two projections are depressed by the force applied to the at least two projections as they engage with the band receiving slot. When the end of the flexible band is slid into the receiving band slot, the at least two ridges engage with at least two recesses or through-holes in the flexible band receiving slot, thereby connecting the flexible band to the disposable clamp.

[0035] In one embodiment, the flexible band may be formed from commonly available plastic or other suitable material. At least one notch may be cut into the end of the flexible band, forming at least two protrusions. Each of the at least two protrusions, in one embodiment, may have at least one protrusion or ridge formed thereon. The at least one protrusion or ridge on each of the at least two protrusions may be of a different shape, forming at least two protrusions at each end of the flexible band. In another embodiment, the shape of the at least one ridge or ridge on each of the at least two protrusions may be serrated or barbed or any suitable shape, sized to fit into at least two through-holes or recesses in the clamp band slot. In another embodiment, two notches are cut into the end of the disposable band to form upper, middle, and lower protrusions, each of the at least two protrusions having at least one ridge. At least one ridge on each of the intermediate and top projections is, in some embodiments, sized to engage with at least two recesses or at least two through-holes in a band-receiving slot formed in the side of the disposable clamp body.

[0036] The maximum distance between the at least one ridge on the upper projection and the at least one ridge on the lower projection is slightly greater than the height of the band receiving slot. Slightly greater is defined as about 0.01 to about 0.15 inches (about 0.0254 to about 0.381 cm) greater. When the flexible band is engaged with the disposable band receiving slot, the at least two ridges are depressed as they are engaged with the band receiving slot. When the end of the flexible band is slid into the band receiving slot, the at least one ridge engages with the at least two recesses or at least two through-holes in the flexible band receiving slot, thereby connecting the flexible band to the disposable clamp.

[0037] In some embodiments, the disposable clamp can be molded or formed as a monolithic component from plastic, metal, or both. In other embodiments, the clamp can be assembled from separate pieces that are press-fit together using barbed or serrated recesses and protrusions. Such separate pieces could also be glued or welded together.

[0038] The drainage bag drape can be made from a flexible, waterproof polymer and, in some embodiments, can be circular or semicircular in shape. In some embodiments, the drainage bag drape is transparent, with its upper portion attached to a flexible band that can be attached to a disposable clamp. The disposable clamp can be attached to the operating table rail or to the mounting arm of an accessory mounting clamp. The drainage bag drape is "V" shaped, with a larger top than the bottom, and the bottom terminates in a hole through which a threaded tube can be attached. In some embodiments, the threaded tube can be attached to a hole in the bottom of the drape by mechanical or adhesive means. The threaded tube can be attached to another threaded tube that is connected to a fluid collection system that stores fluid. In some embodiments, the drape has a filter between the top and bottom of the drape. The filter can be in the form of a mesh, which can be made, for example, from cross-woven yarns of a flexible polymer material.

[0039] In a related aspect, a drainage bag system configured to be coupled to a medical procedure table is disclosed, including a drainage bag, a band that attaches to and supports the drainage bag, the band having at least one ridge on at least one end thereof, and at least one mounting clamp that includes a receiving slot configured to receive the at least one ridge on the band. The clamp has a receiving channel configured to receive a procedure table accessory rail or its accessory mount arm. The clamp has a threaded member configured to secure the clamp to the procedure table accessory or accessory mount arm.

DETAILED DESCRIPTION OF THE INVENTION

[0080] The present disclosure generally relates to a drainage bag system configured to couple to a surgical table. Various terms are used herein in accordance with their ordinary meaning in the art. As used herein, the term "about" is intended to indicate up to a 10% variation for a numerical value. As used herein, the term "surgical table" generally refers to a medical table used when performing a medical procedure on a patient, such as a urological or gynecological procedure.

[0081] The phrase "semi-rigid component" is defined as a member or component that is formed or constructed such that when a force is applied to its center, the elongation (change in length) of the unloaded length of the member is greater than 0% and less than 0.10% before failure.

[0082] The phrase "flexible component" is defined as a component or member that is formed or constructed such that when a force is applied to its center, the elongation of the unloaded length of the member is 0.10% or greater.

[0083] Figures 1A and 1B show stirrups mounted on an operating table using a conventional system, with and without a drainage bag system. The stirrup 02A in Figure 1A is attached to the operating table 11A by a rail clamp 07A. The patient's leg 01A is held in place by a stirrup boot 03A, which is supported by a stirrup gas cylinder 04A attached to the stirrup at a distal stirrup attachment point on 14A and a proximal stirrup gas cylinder mounting lug 05A attached to a stirrup bracket 00A. As shown in Figure 1A, a disposable clamp 12A holds a flexible band 13A to which a drainage bag 14A is attached. The attachment point of the disposable clamp 12A on the operating table rail 10A allows the table clamp 07A and the attachment point of the stirrup 02A to be moved proximally down the operating table rail 10A, toward the patient's head, a distance equal to "x." The center of rotation of the proximal stirrup locking joint 09A in FIG. 1A is offset from the center of rotation of the patient's hip 08A. This offset is caused by the attachment of a disposable rail clamp 12A on the distal end of the operating table rail 10A at a distance "x." FIG. 1B illustrates a stirrup installation without the use of a current technology disposable drainage bag system. In FIG. 1B, the rotation points of the patient's hip 08B and the proximal stirrup locking joint 09B are coextensive in the horizontal plane and are therefore aligned by properly positioning the rail clamp 07B on the distal end of the operating table rail 10B of the operating table 11B. The patient's leg 01B is held within the stirrup boot 03B of the stirrup 02B and supported by the stirrup gas cylinder 04B at the distal stirrup attachment point 14B and the proximal stirrup gas spring mount lug 05B attached to the stirrup mount bracket 00B.

[0084] 2A and 2B schematically illustrate a disposable drainage bag system 110 according to one embodiment of the present teachings attached to a side rail 106 of an operating table 107. The drainage bag system 110 includes a flexible band 105 to which a drainage bag 101 having a mesh filter 104 is attached, and first and second disposable clamps 100A and 100B shown attached to the distal end of the operating table side rail 106. Attached to the drainage bag 101 is a drainage tube 103 and a fluid storage system 102. The drainage bag drape 110 is supported and held open by the flexible band 105 during surgery. The flexible band 105 is coupled to the disposable clamps 100A and 100B, which can then be attached to the distal end of the side rail 106 of the operating table 107. A threaded tube 103 attached to the fluid reservoir 102 engages and attaches to the flap 111 to allow fluid to flow from the drainage bag 101 to the fluid storage system 102 .

[0085] The illustrated drainage bag 101 is constructed from a flexible sheet of thin, translucent plastic material and has flaps 111 attached thereto. In this embodiment, the drainage bag 101 is substantially V-shaped with a mesh filter 104 constructed from thin, flexible strips of polymeric material laid in an alternating or crisscross pattern, and the drainage bag 101 includes flaps 111 attached to holes 101 a (not shown) in its bottom to allow fluid to exit the system and enter the reservoir 102. The mesh filter 104 collects waste products that may be by-products of the surgical procedure and, if not captured within the mesh filter, could prevent fluid from collecting within the fluid reservoir 102 by clogging the threaded tube 111. In other embodiments, there is no mesh filter.

[0086] A number of different polymeric materials may be employed to construct the drainage bag, some examples of which include, but are not limited to, high density polyethylene, low density polyethylene polypropylene, medium density polyethylene, or degradable olefin materials.

[0087] As shown in FIG. 2B, the flexible band 105 has two notches 116 cut into its end to form upper and lower protrusions 115. The upper and lower protrusions 115 have two ridges 113 formed thereon. In this embodiment, the disposable drainage bag 101 has a sleeve 112 into which the flexible band 105 with protrusions 115 and their associated serrated distal ridges 113 can be inserted. It is understood that the serrated ridges are merely exemplary. In other embodiments, the ridges may be circular, serrated or barbed, straight buttons, hooks, pegs, or other shapes. The sleeve 112 of the disposable drainage bag 101 fits around the flexible band 105, connecting the disposable drainage bag 101 to the flexible band 105. The flexible band 105 supports the disposable drainage bag 101 and holds it open, as shown in FIG. 2A.

[0088] The flexible band 105 is horizontally flexible and vertically semi-rigid. The horizontal flexibility of the flexible band 105 allows it to bend in response to a clinician's movement relative to or contact with the band, allowing the clinician access to the operating table 107 without obstructing the disposable drainage bag system 110. In this embodiment, the disposable flexible band 105 is made from a flexible plastic, but in other embodiments, it can be made from other suitable materials. The disposable clamps 100A and 100B are substantially equivalent mirror images of each other. As described in more detail below, the disposable clamps 100A and 100B can be attached to the distal end of an operating table rail 106 of the operating table 107.

[0089] 2C shows detailed aspects of an embodiment of the above-described flexible band 105 (referred to herein for ease of description of the various components as flexible band 213), disposable drainage bag 101 (referred to in this example as disposable drainage bag 214), disposable clamp 200 (which may correspond to one of disposable clamps 100A / 100B), and accessory mount clamp 215. In the embodiment shown in FIG. 2C, disposable clamp 200 has upper ledge 205 with upper ledge chase 231 and extended stabilizer 202. Additionally, disposable clamp 200 has both an outer surface (not shown) and an inner surface 209 that forms rail-receiving channel 208.

[0090] In this embodiment, the lower surface 205a of the upper ledge 205, together with the upper ledge chase 231 and the stabilizer extension 203, form the upper surface of the rail-receiving channel 208, and the lower ledge 206, together with the stabilizer extension 203, form the lower surface of the rail-receiving channel 208. In some embodiments, a lip 210 extends downwardly from the upper ledge 205 and forms one proximal surface of the rail-receiving channel 208, while a lip 211 extends from the lower ledge 206 and forms another proximal surface of the rail-receiving channel 208. A distal surface 209 forms the proximal surface of the rail-receiving channel 208. In this embodiment, the threaded knob 201 engages and fits into a threaded hole (not shown) in the lower ledge 206. In other embodiments, the threaded hole can be formed in the upper ledge 205. Instead of the threaded knob 201, a bolt or any other suitable fastener such as a cotter pin, a threaded pin with lugs, etc. may also be used.

[0091] In the embodiment shown in FIG. 2C , when the operating table rail (not shown) or mount arm 218 of accessory mount clamp 215 with fins 230 is engaged within the operating table rail-receiving channel 208 of disposable clamp 200, threaded knob 201 can enter and engage through a threaded hole (not shown) in lower ledge 206. Engagement of threaded knob 201 into the threaded hole (not shown) secures the disposable clamp to the operating table rail (not shown) or accessory mount arm 218 via its fins 230. More specifically, this view shows that fin 230 fits into upper ledge chase 231 as the threaded knob enters and engages through the threaded hole in lower ledge 206 (not shown). After the surgical procedure is completed, threaded knob 201 can be disengaged from the hole in lower ledge 206 to disengage and remove disposable clamp 200 from mount arm 218 with fins 230 (or operating table rail).

[0092] In this embodiment, when the operating table rail (not shown) or mounting arm 218 with fins 230 is engaged within the rail-receiving channel 208 of the disposable clamp with upper ledge chase 231 and stabilizer extensions 202 and 203, the disposable clamp 204 is protected from any twisting or rotational forces that may be encountered. In this embodiment, the disposable clamp 200 has a flexible band-receiving slot 207 formed in one of its sides. The band-receiving slot 208 has two through-holes formed therein, one above the band-receiving slot 207 (shown) and one below it (not shown).

[0093] However, in other embodiments, band-receiving slot 207 may have more than two through-holes formed therein, or in still other embodiments, only one through-hole. It should also be understood that while through-holes are shown in this embodiment, band-receiving slot 207 may have recesses formed therein in other embodiments. In this embodiment, through-hole 204 in band-receiving slot 207 is shown as straight, but it should be understood that through-hole 204 may have a different shape than that shown in FIG. 2C . Alternatively, as noted above, rather than one or more through-holes, band-receiving slot 207 may have recesses formed therein in other embodiments.

[0094] In this embodiment, the disposable flexible band 213 is attached to the sleeve 228 of the disposable drainage bag 214, as shown in FIG. 2C. The flexible band 213 has notches 230 cut into its end to form insertion projections 229 with serrated ridges 212. In this embodiment, the maximum distance "Z" between the serrated ridges 212 is slightly greater than the height of the band-receiving slot 207. As used herein, the phrase "slightly greater" is defined as 0.01 inches to 0.15 inches (0.0254 cm to 0.381 cm) greater. The band 213 may also include one or more tabs configured to fit into a slot (or slots) formed in the back of the disposable clamp 200 to secure the band 213 to the disposable clamp 200. When the ends of flexible band 203 are engaged within band receiving slots 207, ridges 212 are slightly depressed to release tension on them as they engage through-holes 204, engaging ridges 212 within holes 204 and connecting flexible band 213 to disposable clamp 200. In other embodiments, through-holes 204 may be recesses sized to receive ridges 212.

[0095] 2C includes an accessory mount clamp 215 having an upper arm 216 with a hole 220, a lower arm 217 with a threaded hole 221, a semicircular portion 219 having a mount arm 218 with fins 230, and a spacer 223 with a through-hole 224. A connecting rod 225 includes a threaded end 227 with a flat head on end 226. The connecting rod 225 is pressed into the hole 220 formed in the upper arm 216, passes through the hole 222 in the spacer 223, and exits the hole 224 to engage with the threaded hole 221 in the lower arm 217, thereby securing the spacer 223 to the accessory mount clamp 215. In this embodiment, the accessory mount clamp 215 is formed as a monolithic structure from plastic or metal, although it is understood that each of the components can be assembled by gluing, press-fitting, or welding these parts together in any combination. While the spacer 223 in this embodiment is shown as a linear block, in other embodiments it may be a square, circular, semicircular, or "T" shaped monolith. The rail-receiving channel 208 with the extended stabilizers 202 and 203 of the disposable clamp 200 can engage with the mount arm 218, while the mount arm fin 230 can engage with the upper ledge chase 231 of the accessory mount clamp 215.

[0096] 3 shows another perspective view of an embodiment of a flexible band 313, a disposable drainage bag 321, a disposable clamp 300, an accessory mount clamp 316, a spacer 322, and a rod 326. The flexible band 313 is engaged with a sleeve 320 of the drainage bag 321. In this embodiment, the disposable clamp 300 has an upper ledge 305. The upper ledge 305 and the extended stabilizer 302, together with the proximal surface of the clamp wall 309, form the distal surface of the rail-receiving channel 308. In this embodiment, an upper ledge chase 334 is formed on the underside of the upper ledge 305.

[0097] Stabilizer extension 302 of upper ledge 305 forms the upper surface of rail-receiving channel 308, while lower ledge 331 with stabilizer extension 303 forms the lower surface of rail-receiving channel 308. In some embodiments, threaded knob 301 engages and fits into a threaded hole (not shown) in lower ledge 331. When engaged in rail-receiving channel 308, threaded knob 301 engages accessory mount arm 318 via fins 315 in rail-receiving channel 308. In this embodiment, flexible band 313 has two notches 333 cut into its end to form upper and lower protrusions 330 with ridges 312. The maximum distance between ridges 312, referred to as "Z," is slightly greater than the height of flexible band-receiving slots 307 in disposable clamp 300. As noted above, the phrase "slightly larger" as used herein is intended to indicate approximately 0.01 inches to approximately 0.15 inches (approximately 0.0254 cm to approximately 0.381 cm) larger. When the end of flexible band 313 is engaged with band receiving slot 307 of disposable clamp 300, ridge 312 is pressed down slightly, creating tension due to the engagement of ridge 312 with hole 304 in band receiving slot 307, securing disposable clamp 300 to flexible band 313.

[0098] FIG. 3 illustrates an embodiment of an accessory mount clamp 331 including an upper arm 316 with a hole 320, a lower arm 317 with a threaded hole 321, a semicircular portion 319 with a mounting arm 318 with fins 315, and a spacer 322 with a through-hole 323. In this embodiment, the spacer 322 with a flange 324 is shown as a "T"-shaped piece, but it is understood that the spacer 322 may be square, linear, spherical, hemispherical, or any other suitable shape. A connecting rod 326 includes a threaded end 325 with a flat head on end 327. The connecting rod 326 is pressed into the hole 320 in the upper arm 316, threads through the through-hole 323 in the flange 324 of the spacer 322, and exits the hole to engage the threaded hole 221 in the lower arm 217, thereby engaging the spacer 322 with the accessory mount clamp 331.

[0099] In this embodiment, the "u" shaped portion of accessory mount clamp 331 is formed as a monolithic structure from plastic and / or metal, although in some embodiments mount clamp 331 can be formed as separate components that are assembled together, for example, by gluing, press fitting, or welding. Rail-receiving channel 308 with extended stabilizers 302 and 303 and upper ledge chase 334 of disposable clamp 300 can engage mount arm 318 of accessory mount clamp 331.

[0100] FIG. 4 shows an embodiment of a flexible band 400 engaged within a disposable clamp 401 and attached to a sleeve 412 of a disposable drainage bag 411, which is then connected to an accessory mount clamp 413. In this embodiment, the flexible band 400 is fully engaged within a flexible band receiving slot 415. The flexible band has notches 420 cut into its ends to form upper and lower protrusions 421. Ridges 414 are formed on the protrusions 421. The distance "Z" between the ridges 414 is slightly greater than the height of the band receiving slot 415 of the disposable clamp 418. As noted above, the phrase "slightly greater" as used herein indicates approximately 0.10 to 0.15 inches (approximately 0.254 to 0.381 cm) greater.

[0101] When the end of flexible band 400 engages band-receiving slot 415, ridge 414 is pressed down slightly, creating tension so that ridge 414 engages through-hole 414, thus securing flexible band 411 to disposable clamp 418.
