[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of U.S. Provisional Patent Application No. 62 / 871,146, entitled "Traction Tower Trap and Finger Trap System," filed July 7, 2019, and U.S. Provisional Patent Application No. 62 / 930,115, entitled "Traction Tower Scale," filed November 4, 2019, and is related to PCT application PCT / US20 / 16170, entitled "Wrist Traction Tower," filed January 31, 2020, which are incorporated by reference in their entireties.

[0002] FIELD OF THEINVENTION The present invention relates to orthopedic surgical procedure positioning devices / systems, and more particularly to wrist traction tower trap and finger trap systems. [Background technology]

[0003] 2. Description of Related Art During arthroscopic surgery at the wrist, for example, surgeons use traction to create sufficient space in the wrist joint for proper and efficient use of the arthroscope and other related instruments. Conventional traction towers are commonly used to create such traction necessary for wrist arthroscopic surgery procedures, radiographic procedures, and other related medical procedures. Straps and finger traps are used in conjunction with traction towers to aid in positioning and distracting the patient's arm for orthopedic hand and wrist surgical procedures. The straps provide an atraumatic method of securing the patient's forearm and biceps to the traction tower. The finger traps maintain an atraumatic method of securing the patient's fingers. However, conventional traction tower straps and finger traps have limited ability to accommodate a wide variety of individual patient sizes and are difficult to tighten and release for each patient.

[0004] Therefore, there is a need for easily adjustable and removable tow tower straps and finger traps.

Summary of the Invention

[0006] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE PRESENT EMBODIMENTS OF THE PRESENT EMBODIMENT are directed to a wrist traction tower and associated traction tower scale. Wrist traction tower embodiments are directed to a system having multiple parts, one or more of which are configured, mounted, positioned, and / or structured to move (e.g., slide, telescope, pivot, twist, turn) relative to one or more of the other parts of the system. Such adjustability, maneuverability, and flexibility provide an improved and enhanced orthopedic medical procedure positioning system (compared to conventional devices / systems), which allows physicians to and its respective instruments can accommodate a wide range of patient arm lengths and sizes while providing ample space for performing surgery, x-rays and other related medical procedures. Elements of the tow tower system of embodiments can be made from aluminum, stainless steel, brass, and plastic (PEEK).

[0007] According to one aspect, the present invention is a towing tower assembly. The towing tower assembly may include a first tower having a first side and a second tower having a second side positioned adjacent to the first side, the second tower being movable in a first direction and a second direction relative to the first tower, and an elongated arm assembly attached to and extending from the tower assembly. A towing tower scale may also be part of an embodiment of the present invention.

[0008] The present invention takes into consideration that, in one preferred embodiment, when positioning the height of the upper tower and connected arm assembly relative to the lower tower, the wrist joint of an individual patient should be approximately one inch above the rotational joint (specified below). This allows a physician, for example, to x-ray the wrist while still attached to the traction tower. If metal is too close to the wrist joint, it may affect the x-ray image.

[0009] These and other aspects of the invention will be apparent from and elucidated with reference to the embodiment(s) described hereinafter. [Brief description of the drawings]

[0012] Aspects of the present invention and its specific features, advantages, and details are described more fully below with reference to non-limiting examples illustrated in the accompanying drawings. Descriptions of well-known structures are omitted so as not to unnecessarily obscure the details of the invention. It should be understood, however, that the detailed description and specific non-limiting examples, while illustrating aspects of the present invention, are given by way of illustration only and not by way of limitation. Various substitutions, modifications, additions, and / or arrangements within the spirit and / or scope of the underlying inventive concept will be apparent to those skilled in the art from this disclosure.

[0013] Referring now to the drawings, in which like reference numbers refer to like parts throughout, FIG. 1 shows an exploded perspective schematic of a towing tower 100, according to one embodiment. FIG. 2 and FIG. 3 show assembled perspective schematics of the towing tower 100 shown in FIG. 1, according to one embodiment. As shown, the towing tower 100 includes a base plate 1, a tower assembly, and an arm assembly. The tower assembly has mated parts of a lower tower 2 and an upper tower 3, showing that the upper tower 3 is movable relative to the lower tower 2 (as will be further discussed below). The lower tower 2 is removably securable (via any attachment means 15, including clips, keyed sliding and locking mechanisms, nuts and bolts, etc., as should be understood by those skilled in the art in conjunction with this disclosure) on the base plate 1. In addition, the lower tower 2 may include a peg 2-2 that is biased in a downward direction (protruding from the bottom surface of the lower tower 2) via a spring (not shown) located on the lower tower 2. The peg 2-2 is lifted by a sliding button 2-1 and fully positioned within the lower tower 2. Peg 2-2 can fit into holes (not shown) formed in base plate 1 and can rotate the lower tower (clockwise or counterclockwise) to assist in locking lower tower 2 to base plate 1. According to one embodiment, all other elements / components of towing tower 100 are movable relative to at least one other element / component of towing tower 100, but need not be movable.

[0014] 1-3, the lower tower 2 is L-shaped and configured to fit snugly into the upper tower 3 as shown. The tower assembly may include additional components and may include multiple shapes as long as the components fit together in a snug arrangement and the overall movement and locking functions remain similar or the same as described herein. The tower assembly components (here the lower tower 2 and the upper tower 3) can be secured / locked by a locking knob 4. The stem 4-1 of the locking knob 4 can be placed through a lateral opening located on each of the lower tower 2 and the upper tower 3, and the knob end can be rotated to secure each tower component (as should be understood by those skilled in the art in conjunction with a review of this disclosure). The opening of the upper tower 3 is configured to snugly fit, engage, and secure the stem of the locking knob 4 when the knob end is rotated in the appropriate direction (and disengage when the knob is rotated in the opposite direction to lock the upper tower 3). The openings 2-3 in the lower tower 2 extend up and down (partially shown in FIG. 9 ) to allow the upper tower 3 to move up and down relative to the lower tower 2, which can be relocked to the lower tower 2 by use of a locking knob 4 (described herein and to be understood by those skilled in the art in conjunction with a review of this disclosure). According to additional embodiments, the lower tower 2 may include different or additional elongated openings that allow relative movement of the upper tower 3 to the lower tower 2 diagonally, horizontally, or in other directions at an angle to the vertical direction B---B when assembled. According to an alternative embodiment, the types of openings may be reversed between the upper tower 3 and the lower tower 2. The upper tower 3 may also include openings or through-holes 14 (vertical or otherwise shaped) that can accommodate straps for holding the patient's forearm to the traction tower 100. The upper tower 3 also includes alignment pegs 3-3 configured to fit into corresponding elongated holes (top and bottom, not shown) in the lower tower 2. This alignment peg 3-3 acts in conjunction with the stem 4-1 to assist in aligning the upper tower 3 with respect to the lower tower 2 and prevent undesired movement / rotation of the upper tower 3 with respect to the lower tower 2 when the relative height of the upper tower 3 is adjusted with respect to the lower tower 2.

[0015] With continued reference to Figures 1-3, the revolute joint 5 connects the tower assembly to the arm assembly. The stem 13 of the revolute joint 5 is positioned and rotatable in the upper tower 3 (as shown, positioned through the top surface 3-1 of the upper tower 3, as discussed further below). The top surface 3-1 of the upper tower is configured to extend along a plane at an angle to the plane of the bottom surface 3-2 and / or the base plate 1A---A when assembled. Alternatively, the top surface 3-1 may extend along a plane parallel to the plane of the base plate 1A---A. A first end of the lower arm 6 includes a slotted base end 12 that is removably positioned, rotatable, and lockable within the head 5-1 of the revolute joint 5 (as discussed further below). The lower arm 6 extends from the slotted base end 12 and the elongated lower end 6-1 to a curved portion 11 of the lower arm 6 that extends to an elongated upper end 6-2 of the lower arm 6. The upper end 6-2 of the lower arm 6 extends at an angle to the axis of the elongated lower end 6-1 (which may be any angle including 45 degrees, substantially vertical, vertical). The elongated lower end 7-1 of the upper arm 7 fits within the elongated upper end 6-2 of the lower arm 6, which may be solid or not, but is formed as a tube, and is telescopically movable. A lever 8 is connected to the elongated upper end 6-2 of the lower arm 6. The lever 8 includes a protrusion or tooth on an end positioned within the elongated upper end 6-2 of the lower arm 6, which may be positioned and fitted between ridges 7-4 formed on at least one side of the elongated lower end 7-1 of the upper arm 7 (which faces the protrusion or tooth of the lever 8 when the elongated lower end 7-1 of the upper arm 7 is positioned within the elongated upper end 6-2 of the lower arm 6). When the lever 8 is actuated in a first direction that positions the protrusion or tooth between one of the pair of ridges 7-4, the upper arm 7 is fixed / clamped / locked relative to the lower arm 6. When the lever 8 is actuated in a second direction, the upper arm 7 is released from its fixed / clamped / locked position and is free to move relative to the lower arm 6 (e.g., further into or out of the lower arm 6).According to an alternative embodiment, upper arm 7 may be tubular in construction and lower arm 6 may (but need not be) solid / non-tubular and include ridges (essentially the opposite configuration shown in FIG. 1). Lever arm 8 may be any type of actuator including a linear slider, circular actuator, or switch, etc. (as should be understood by one of ordinary skill in the art in conjunction with review of this disclosure).

[0016] The elongated lower end 7-1 of the upper arm 7 extends from the lower arm to a curved portion 7-2 of the upper arm 7 which extends to an elongated upper end 7-3 of the upper arm 7. The upper end 7-3 of the upper arm 7 extends at an angle to an axis of the elongated lower end 7-1 (which can be any angle including 45 degrees, substantially perpendicular, vertical) and essentially the same distance as the elongated lower end 6-1 of the lower arm 6 (which can extend in a plane that is parallel or substantially parallel, but need not be). (As shown, the elongated lower end 6-1 of the lower arm 6 is oriented slightly more in a relatively downward direction and extends in a plane parallel or substantially parallel to the plane A----A, as compared to the elongated upper end 7-3 of the upper arm 7.) The elongated upper end 7-3 of the upper arm 7 includes a through hole 7-5 configured to assist in securing a towing tower scale thereto (embodiments of a towing tower scale and its attachment to a towing tower are discussed further below).

[0017] As mentioned above, there are several structural features and configurations that allow the entire traction tower 100 to be properly sized for an individual patient. In addition, when the height of the upper tower 3 is adjusted (as described below with respect to Figures 4-5), the forearm strap location 14 moves with it, always relatively close to the patient's wrist (the closer to the wrist the strap has better control). If the straps were in one fixed location they would not work well with different patient sizes.

[0018] 4-5, close-up perspective schematic views of the lower portion of the traction tower 100 shown in FIG. 1 are provided, according to one embodiment. FIGS. 4-5 are provided to illustrate the movement of the upper tower 3 relative to the lower tower 2 to accommodate various individual patient forearm sizes, and the structural features that enable such movement. FIG. 4 illustrates the upper tower 3 in its relatively lowest position relative to the lower tower 2, and FIG. 5 illustrates the upper tower 3 in its relatively highest position relative to the lower tower 2.

[0019] 4, it is shown that the upper tower 3 fits snugly within the contour of the lower tower 2 at the upper tower 3's lowest point. As shown, the upper tower 3 and the lower tower 2 are held together by a locking knob 4 (discussed above). To aid in locking the upper tower 3 and the lower tower 2, an interlockable wave / sawtooth pattern 16 may also be provided on each of the laterally facing surfaces of the upper tower 3 and the lower tower 2. The wave / sawtooth pattern 16 may cover the entirety of each of the laterally facing surfaces of the upper tower 3 and the lower tower 2, or less than the entirety of each surface. As also mentioned above, the upward adjustment of the upper tower 3 is accomplished by (1) loosening the lock knob 4 and the connection between the upper tower 3 and the lower tower 2, (2) moving the knob 4 and the upper tower 3 in the elongated opening 2-1 (not shown) from the position shown in FIG. 4 upward to the position shown in FIG. 5, and then tightening the lock knob 4 and the upper tower 3 in the new position, and (3) the upward movement of several other elements, including the strap for the patient's arm (not shown), the positionable through opening 14, the rotating joint 5 and the arm assembly, relative to the lower tower 2 as a result of the movement of the upper tower 3 upward along the arrow C. The same actions can be performed to move the upper tower 3 in the opposite direction (i.e., starting with loosening the lock knob 4, moving the lock knob 4 and the upper tower 3, etc., in the opposite direction, etc.).

[0020] As mentioned above, the top surface 3-1 of the upper tower is configured to extend along a plane that is positioned at an angle relative to the plane of the base plate 1A---A when assembled (see FIG. 1). The revolute joint 5 attached to the top of the upper tower 3 includes a rotation axis A1 that extends at an angle relative to a straight up-down vertical axis - see FIG. 1B---B. By having the revolute joint 5 house a portion of the lower arm 6 and positioned at an angle with the angled rotation axis A1 (see FIG. 6 showing the rotation axis A1 created by angling the revolute joint 5 and its stem 13 positioned on the upper tower 3), rotation of the revolute joint 5 and the arm assembly (discussed further below) does not displace the point at which traction is produced (as should be understood by those skilled in the art in conjunction with a review of this disclosure). This means that the arm assembly can be moved without losing traction on the patient's arm or its position, as shown in FIGS. 7-8.

[0021] 7 and 8, there are shown top and perspective schematic views illustrating the range of rotation of the revolute joint 5 (and therefore the arm assembly) of the towing tower 100 about the axis of rotation A1. The rotation D (see, for example, FIG. 6) of the revolute joint 5 / arm assembly about the axis of rotation A1 can be incremental, locked / unlocked via slot / tooth embodiments, as discussed with respect to the additional rotation features (see those discussed with respect to FIGS. 18D-E), non-incremental when locked / unlocked via frictional engagement, or locked / unlocked via other known locking / unlocking mechanisms (as should be understood by those skilled in the art in conjunction with a review of this disclosure). The range of rotation is indicated by the shadowed (transparent) arm assembly structure 20 positioned around a start or zero position indicated by the solid arm assembly structure 30. The position of the screw (not shown) that holds the towing scale at 7-5 is consistent regardless of the rotation of the other parts of the arm assembly. As shown in FIG. 8, the majority of the arm assembly is offset from the patient's arm in use, regardless of the rotational position of the arm assembly, to create sufficient space for surgical instruments. In other words, this structural configuration and associated features allow the physician to move the arm assembly around the patient's hand without affecting the position or traction of the hand itself. The ability to rotate the arm assembly can be important if the physician needs more space around the outside of the wrist joint for medical instruments, as the physician can simply rotate the arm assembly behind the arm. Another use of this structural feature includes allowing the physician to manipulate the arm assembly while the wrist is in traction in order to put a c-arm (x-ray machine) in position to take an x-ray.

[0022] Referring to FIG. 9, an enlarged partial cross-sectional perspective view of the lower portion of the traction tower 100 is shown, according to one embodiment. The interface between the slotted base end 12 of the elongated lower end 6-1 of the lower arm 6 and the revolute joint 5 is shown. In particular, the slot / teeth formed on the slotted base end 12 allow incremental rotation of the arm assembly about the second axis of rotation E---E, as shown in FIGS. 10 and 11. The primary purpose of the rotation of the elongated lower end 6-1 of the lower arm 6 about the second axis of rotation E---E is to allow the physician to control the angle of the patient's wrist during use by keeping the patient's forearm vertical and pulling traction to the hand at an angle (or perpendicular) from the elongated axis positioned through the patient's forearm, as should be understood by those skilled in the art in conjunction with a review of this disclosure. To allow rotation of the arm assembly about the second axis of rotation E--E, button 5-2 may be pressed (a force acting against button 5-2 opposite the spring bias) to overcome the biasing force applied by a spring (not shown) downwards towards button 5-2 relative to button housing 5-3 and remove locking teeth 5-4 located between two respective slots / teeth of slotted base end 12. When a desired position of the arm assembly is reached, the force applied by the user against button 5-2 may be removed and the arm assembly may be locked in the desired position via the interlocking mechanism described (the biasing force applied by the spring presses locking teeth 5-4 between another two slots / teeth of slotted base end 12).

[0023] 10-11, there are shown perspective schematic diagrams illustrating the range of rotation of the elongated lower end 6-1 (and therefore the arm assembly) of the lower arm 6 of the towing tower 100 about the axis of rotation E---E. The rotation F of the elongated lower end 6-1 of the lower arm 6 about the axis of rotation E---E may be incremental and locked / unlocked via a slot / tooth embodiment as shown and described with respect to FIG. 9, or may be non-incremental when locked / unlocked via frictional engagement or locked / unlocked via other known locking / unlocking mechanisms (as should be understood by those skilled in the art in conjunction with a review of this disclosure). An example of the range of rotation for the control of the wrist angle is shown by the shadow (transparent) arm assembly structure 20 positioned around a start or zero position indicated by the solid arm assembly structure 30.

[0024] Referring to FIG. 12, a perspective schematic diagram of a towing tower 100 with the lever 8 and ridge 7-4 engagement structure and resulting functionality according to one embodiment is shown in a partially transparent view. Briefly, a height adjustment mechanism is formed between the upper arm 7 and the lower arm 6. This interface between the upper arm 7 and the lower arm 6 allows for separate adjustment points to accommodate a wide variety of individual patient arm sizes. The adjustment mechanism illustrated in FIG. 12 includes a latch mechanism for quick height adjustment by actuating the lever 8 to position end 8-1 within a selected / specific notch formed in the upper arm 7 at 7-4.

[0025] 13-14B show a towing tower scale 200 according to one embodiment. Referring to FIG. 13, a perspective view of the towing tower 100 is shown along with the towing tower scale 200. The towing tower 200 includes a tubular body 211 attached to a distal end of the upper end 7-3 of the upper arm 7, including, but not limited to, via welding, screws, nuts and bolts, or other known attachment means, which should be understood by one of ordinary skill in the art in conjunction with a review of this disclosure. The tubular body 211 includes a knob 209 and is configured to be attached to a spring (not shown) positioned thereafter through the top of the tubular body 211. A rod / screw 213 attached to the lower end of the spring is positioned partially within the tubular body 211 and a portion of it protrudes outside the lower end of the tubular body 211. The lower end of the rod / screw 213 includes a hole that receives the clip 207 therethrough. The other end of the clip 207 is attached to a hole formed in or on the rack 203. The rack is shown with two finger traps 201 (although it may include one or more) for immobilizing the patient's fingers and applying traction.

[0026] 14A-B show perspective schematic diagrams of a towing tower scale 200 according to one embodiment. The rack 203 (to which the finger trap 201 is attached) is directly connected to the knob 209 through a rod / screw 213 (which can be any type of connecting element capable of performing the functions of the rod / screw 213 described herein, not necessarily a rod or a screw). In a pre-use "rest state" (not attached to, or at least not receiving force from, a patient's finger), the knob 209 is biased upwards (see arrow A) by a spring located within the tubular body (which can be any type of spring, including a coil spring with a known biasing force, as should be understood by those skilled in the art in conjunction with a review of this disclosure). A force is applied downwards (see arrow B) to the spring by the weight of the patient's hand / arm (from the finger trap, to the rod / screw 213, to the spring, and to the knob 209), which pulls the knob 209 (including its stem) further downwards into the tubular body 211 of the scale. The stem of knob 209 may include a visual indicator (e.g., a line or other marking) that may be used to indicate the estimated amount of traction used. This may be done by displaying where the visual indicator is in display window 211-2, and its location may be aligned with a groove indicating traction amount number 211-1. The traction force is in pounds. However, preferred embodiments use the traction amount number as a relative reference traction number (e.g., the relative amount of traction applied to the patient's arm / wrist) rather than as a specific measurement device.

[0027] FIGS. 15-26 collectively illustrate a towing tower 100′ according to an alternative embodiment. This alternative embodiment of the towing tower 100′ is similar in many respects (including structurally and functionally) to the towing tower 100 described above with respect to FIGS. 1-12. Accordingly, the following description of the elements / components of the towing tower 100′ is primarily limited to the alternative / different aspects (such as the upper tower 3′ and the revolute 5′). Where structural elements and their resulting (single or collective) functionality are not described, and / or described above, the structure and associated functionality are the same as described above with respect to FIGS. 1-12 and apply in this section (similarly, the discussion regarding the towing tower scale 200 provided in FIGS. 13-14B applies hereinafter to the towing tower 200 shown as part of the towing tower 100′). applies to.

[0028] Referring now to Fig. 15, there is shown an exploded perspective schematic view of a towing tower 100 according to an alternative embodiment. Fig. 15 is similar to Fig. 1, except for the addition of a towing tower 200 (described with respect to Figs. 13-14B) and an alternative embodiment of an upper tower 3' and a revolute joint 5'. Figs. 16 and 17 are assembled perspective schematic views of the towing tower 100 shown in Fig. 15, according to an alternative embodiment, similar to Figs. 2-3, respectively.

[0029] FIG. 18A is an enlarged partial cross-sectional perspective view of the lower part of the towing tower 100 according to an alternative embodiment. As previously described with respect to FIG. 1, the upper tower 3' includes an alignment peg 3-3 configured to fit into a corresponding elongated hole / slot 2-3 in the lower tower 2. The alignment peg 3-3 helps the user to easily position the upper tower 3' on the lower tower 2 before installing the tower lock knob 4. The upper tower 3' also ensures that it remains vertical if / when the user adjusts the height of the upper tower 3' because there are two pins / stems in the slot 2-3 of the lower tower (the pin 3-3 from the upper tower 3' and the threaded rod / stem 4-1 from the tower lock knob 4). In this way, if the height of the upper tower 3' is adjusted after the entire tower is assembled, there is no risk of the entire upper part of the tower 100' (the arm assembly) rotating and swinging down when the tower lock knob 4 is loosened. In this embodiment, height adjustment can be achieved by loosening the tower lock knob 4 without completely removing it from the lower tower / upper tower.

[0030] 18B-18C, there are shown an enlarged perspective view and a solid line view, respectively, of the lower portion of the towing tower 100' according to an alternative embodiment. The lower tower 2 includes a sliding button 2-1 attached to a locking peg 2-2. A spring 2-4 biases the sliding button 2-1 and the peg 2-2 in a downward direction, which can be overcome by the user sliding button 2-1 moving the peg 2-2 upward within the tubular body of the lower tower 2. The purpose of the peg 2-2 and the attachment means 15 (here a key lock mechanism) is to ensure that the lower tower 2 locks to the base plate 1 when it is attached and does not move until the tower 100' is ready to be disassembled. Also, when assembling the tower 100', the user can quickly assemble and passively lock the tower (since the peg 2-2 is spring-loaded in the downward position, the sliding button 2-1 does not need to be activated during assembly, and the lower tower 2 is simply pushed into the base 1 and, when twisted, will fall into the base hole 1 when the peg 2-2 is in the right-turned position). The key-lock mechanism 15 is simultaneously placed on the base keyhole 1-1 to assist in locking the lower tower 2 to the base 1 after the twisting action.

[0031] Referring to FIG. 18D, an enlarged partial cross-sectional perspective view of the lower part of the towing tower 100 is shown according to an alternative embodiment. The sliding button 5-7 is shown connected to a locking peg 5-8 that is biased upwards into a hole 5-10 formed in the tubular body of the revolute joint 5 via a spring 5-6. To release the revolute joint about the rotation axis A1 and allow it to rotate freely, the user can press the sliding button 5-7 downwards and remove the locking peg from the hole 5-10 until the desired rotation position is reached. The button can then be released and the spring 5-6 can move the locking peg 5-8 to another hole 5-10 (see FIG. 18E).

[0032] 19-20, enlarged perspective schematic views of the lower portion of the towing tower 100 shown in FIG. 15 are provided in accordance with an alternative embodiment. FIGS. 19-20 are similar to FIGS. 4-5, except for the structural differences discussed herein and above with respect to the rotational joint 5' and upper tower 3'. However, the upper tower 3' is provided with structural features that allow for movement of the upper tower 3 relative to the lower tower 2 to accommodate various individual patient forearm sizes, and such movement. FIG. 19 shows the upper tower 3' in its relatively lowest position relative to the lower tower 2. 20 shows the upper tower 3' at its relatively highest position relative to the lower tower 2. The apertures shown, other than aperture 14, indicate where metal has been removed for weight reduction and thermal management purposes.

[0033] Referring to Figure 21, a perspective schematic view of the lower portion of the towing tower 100 shown in Figure 15 is provided according to an alternative embodiment. Similar to Figure 6, Figure 21 shows a rotation axis A1 formed by aligning a revolute joint 5' located on the upper tower 3' with its stem 13 located therein.

[0034] 22-23, perspective and top schematic views are provided showing the range of rotation of the revolute joint 5 (and therefore the arm assembly) of the towing tower 100 about the axis of rotation A1. FIGS. 22-23 are similar to FIGS. 22-23, respectively.

[0035] Referring to Figure 24, an enlarged partial cross-sectional perspective view of the lower portion of the towing tower 100' is shown, according to one embodiment. Figure 24 is similar to Figure 9, and the elements function in a similar manner, albeit with some structural differences with respect to the revolute joint 5' and upper tower 3' discussed above.

[0036] 25, which is a perspective schematic diagram showing the range of rotation of the elongated lower end 6-1 of the lower arm 6 (and thus the arm assembly) of the towing tower 100 about the axis of rotation E---E. FIG. 25 is similar to FIGS. 10 and 11.

[0037] 26, a perspective schematic diagram of a towing tower 100' is shown in partial transparent view with a height adjustment mechanism including the lever 8 and ridge 7-4 engagement structure and resulting functionality according to an alternative embodiment. FIG. 26 is similar to FIG.

[0038] Referring to Figure 27, a perspective view of a towing tower 100' is shown according to an alternative embodiment. Figure 27 shows the placement of a patient's arms relative to the towing tower assembly 100'.

[0039] 28A-28B, top view photographs of a strap 300 according to two embodiments are shown. The strap 300 is designed for quick connection to the towing tower 100 and easy adjustment of the length of the strap 300 to accommodate various patient sizes. Although the strap 300 can be used to secure the patient's arm in any position, the embodiment of the strap 300 in FIGS. 28A-28B is preferably placed around the patient's biceps. The strap 300 in FIGS. 28A-28B includes a length of material 302 that wraps around the patient's arm (e.g., biceps). The length of material 302 can be constructed from any inflexible material, such as, for example, polyester. The length of material 302 should be inflexible to prevent stretching and relaxation around the patient's arm. The length of material 302 should also be constructed from a material that is non-irritating to the skin while having sufficient friction to allow the length of material 302 to lock in use and slide along itself upon release.

[0040] 28A-B, the length of material 302 includes a pad 304 for patient comfort and safety. The pad 304 is attached to at least a portion of the length of material 302. In the embodiment of FIG. 28A, the pad 304 has a width substantially similar to the width of the length of material 302 such that the pad 304 does not extend beyond the boundaries of the length of material 302. In FIG. 28A, the pad 304 is attached to the length of material 302 with an adhesive or a connector, such as a hook and loop connector, such that the pad 304 can be easily replaced.

[0041] In the embodiment shown in FIG. 28B, the pad 304 extends around at least a portion of the length of material 302. The strap 300 in FIG. 28B is preferably a biceps strap used to hold the patient's biceps to the base plate 1 of the traction tower 100 (hereinafter, the base plate, traction tower, and their components can be any of the previously described embodiments). In FIG. 28B, the pad 304 is cylindrical or tubular. In one embodiment, the pad 304 is a 2-inch wide webbing with foam padding to distribute force to the patient's biceps. The pad 304 may be fixed around the length of material 302 or may be removable (e.g., via adhesive or a seam along the length of the pad 304 that can be attached with a connector). A cylindrical or tubular pad 304 extending around at least a portion of the length of material 302 allows the pad 304 to move or roll slightly along the patient's arm. The ability of the pad 304 to move or roll allows for movement of the patient's arm while maintaining the comfort of the pad 304.

[0042] 28A-28B, the length of material 302 includes one or more adjustment mechanisms 306. The purpose of the adjustment mechanisms 306 is to tighten the strap 300 (i.e., adjust the length of the strap 300) and secure arms of various sizes to the base plate 1 of the towing tower 100. As shown in the illustrated embodiment, the adjustment mechanisms 306 are buckles. Specifically, the length of material 302 in FIGS. 28A-28B has two buckles 306, one on each side of the pad 304.

[0043] In Figs. 28A-B, the length of material 302 is shown woven through the buckle 306, which is substantially equidistant from the pad 304. Further, in Figs. 28A-B, a first end 308 of the length of material 302 extends from the first buckle 306 toward the pad 304, and a second end 310 of the length of material 302 extends from the second buckle 306 toward the pad 304. In use, as shown in Figs. 29A-B, an opening 312 having a first diameter is formed between the base plate 1 of the traction tower 100 and the length of material 302. To secure the patient's forearm to the traction tower, the patient's arm is inserted through the opening 312. The opening 312 is then reduced to a second diameter by pulling the first end 308 and the second end 310 of the length of material 302 through the buckle 306.

[0044] As shown in FIGS. 29A-B, the first and second buckles 306 slide into slots 424, 426 in the base plate 1 and can move toward the center 428 of the base plate 1 to accommodate the size of the patient's arm. In the illustrated embodiment, the slots 424, 426 are on opposing sides of the base plate 1. In FIGS. 29A-B, the slots 424, 426 are aligned so that the central axes of the slots 424, 426 are the same. The advantage of this connection is that the sliding of the buckle 306 in the base plate 1 acts as an additional adjustment mechanism. In particular, as the buckle 306 of the strap 300 moves closer to the patient's biceps, the length of the strap 300 is put under more tension, making the strap 300 more effective at minimizing the opening 312 and limiting movement. If the strap 300 is a biceps strap, it is intended to limit vertical movement of the biceps due to traction applied to the wrist, as well as side-to-side movement that occurs as the surgeon applies force to the wrist during the procedure. The strap 300 in Figures 29A-29B is a forearm strap, much like the bicep strap 300 in Figures 28A-28B. In one embodiment, the forearm strap 300 (Figures 29A-29B) comprises a 2 inch wide webbing that holds the patient's forearm and two plastic buckles 306 that connect to the upper tower component 3 of the traction tower 100 and allow the length of the strap 300 to be adjusted.

[0045] One major advantage of this forearm strap 300 illustrated in Figures 29A-29B is that it connects to the upper tower component 3 of the traction tower 100. The upper tower 3 of the traction tower 100 can be positioned higher or lower based on the patient's anatomy so that the forearm strap 300 is always positioned close to the patient's wrist. The closer the strap 300 is to the lateral forces applied by the surgeon during the procedure, the more effective it will be in preventing side-to-side wrist movement.

[0046] 30A-30C, there are shown schematic front, side and back views of a buckle 306, according to one embodiment. The buckle 306 shown in FIGS. 30A-30C is easily adjustable and has strong locking strength. In the side view shown in FIG. 30B, the buckle 306 has a rounded profile. In other words, the top surface 314 (FIG. 30A) and bottom surface 316 (FIG. 30C) of the buckle 306 are curved to allow the buckle 306 to be comfortably positioned against the patient's arm and to accommodate different arm sizes.

[0047] 30A-30B, the buckle 306 has a rounded top 318 connected to a rectangular adjustability section 320. The adjustability section 320 is connected to a substantially rectangular base 322 having one or more connectors 323 extending therefrom. A side view of the buckle 306 shows that the side profile of the buckle 306 is rounded from the top 318 to the base 322. In FIG. 30C, the bottom surface 316 of the buckle 306 has a ridge 324 that extends around the perimeter of the top 318. The ridge 324 is designed to act as an ergonomic thumb ridge to improve a user's grip on the buckle 306 and facilitate the release of the strap 300 around the patient's arm. The improved grip is particularly beneficial when a user is manipulating the strap 300 with wet gloves.

[0048] As shown in FIG 30C, the bottom surface 316 of the buckle 306 has one or more flanges 326 extending from a base 322. In the embodiment shown in FIG 30C, there are two substantially parallel flanges 326 extending from the base 322. The flanges 326 are triangular in shape, as shown in the side profile of the buckle 306 in FIG 30B. The flanges 326 guide the buckle 306 as the user slides the buckle 306 within the base plate 1 of the towing tower 100. The flanges 326 add rigidity to the base 322, where most of the force on the buckle 306 is applied.

[0049] 30A and 30C, the adjustability section 320 of the buckle 306 includes teeth 328. The teeth 328 extend across the adjustability section 320 and increase the strength of the buckle 306 when tightened. The teeth 328 enhance the grip on the length of material 302 and resist slipping when tightened.

[0050] Returning to FIG. 30B, the overall profile of the buckle 306 is thin. This also allows the buckle 306 to encompass the bottom of the bicep. The buckle 306 has an interference angle that extends along the outer edge 330 of the projection 332 that extends across the adjustability section 320. The interference angle of the buckle 306 of FIG. 30B is steep, within the range of 0-45 degrees. The steep interference angle provides high friction with the length of material 302 during use and easy release when the first end 308 or second end 310 of the length of material 302 is pulled away from the patient's arm.

[0051] 31A-31B, there are shown front and perspective schematic views of a forearm buckle mount 334, according to one embodiment. The forearm buckle mount 334 is attached to the buckle 306 and is used to secure the patient's forearm to the towing tower 100. The forearm buckle mount 334 comprises a rectangular post-like section 336 with one or more posts 338 extending across it. In the illustrated embodiment, the post-like section 336 has The forearm buckle mount 334 has at least two spaced posts 338 extending therefrom. The forearm buckle mount 334 includes an outer flange 340 connected to the post sections 336. The outer flange 340 includes a slot 342. The slot 342 extends along an axis perpendicular to the axis extending through each post 338. The slot 342 is asymmetrical to allow only correct insertion orientation while preventing incorrect insertion orientation. The forearm buckle mount 334 promotes free, low friction rotation of the length of material 302. On a side of the forearm buckle mount 334 opposite the outer flange 340, the forearm buckle mount 334 includes a buckle interface 344 for rotatably mounting to the connector 323 of the buckle 306.

[0052] 32-34, the buckle 306 and forearm buckle mount 334 are shown attached to the towing tower 100. As shown in FIG. 32, an outer flange 340 of the forearm buckle mount 334 extends from a first side 430 of the towing tower 100 and a buckle interface 344 of the forearm buckle mount 334 extends from an opposing second side 432 of the towing tower 100. As shown in a top view in FIG. 33, the buckle 306 is rotatable about the buckle interface 344 of the forearm buckle mount 334 relative to the second side 432 of the towing tower 100. The buckle interface 344 has an audible snap and haptic feedback that indicates that the connector 323 of the buckle 306 is attached to the forearm buckle mount 334. FIG. 35 shows the towing tower 100 with the strap 300 attached. The buckle 306 stays in place within the buckle interface 344 during use and simply releases when the user is done using the buckle 306. The same buckle 306 is used as the fully rotatable bicep strap 300.

[0053] 36, a top schematic view of a finger trap 400 is shown, according to one embodiment. The finger trap 400 has a length of flexible material 402 having a first end 404 and a second end 406. In one embodiment, the length of flexible material 402 is constructed from a mesh or braided material. For example, the length of flexible material 402 may be a double layer mesh material. The length of flexible material 402 is closed at the first end 404 and open at the second end 406. In the illustrated embodiment, the length of flexible material 402 is tapered or funneled with a reduced diameter at the first end 404 and an increased diameter toward the second end 406. The length of flexible material 402 is tubular, rounded, and has an interior volume 408 to facilitate finger insertion. In one embodiment, the length of flexible material 402 is approximately 6 inches long to accommodate fingers of various sizes.

[0054] 36, a fastener 410 is attached at or near the second end 406 of the finger trap 400. In the illustrated embodiment, the fastener 410 is a hook and loop fastener 410. The fastener 410 is woven through the length of flexible material 402 at at least one location. Specifically, as shown in FIG. 36, the fastener 410 extends through the length of flexible material 402 into the interior volume 408 and again outwardly through the length of flexible material 402. The fastener 410 is used to adjust the diameter of the interior volume 408 of the length of flexible material 402 at or near the second end 406. This allows for quick and easy adjustment of the finger trap 400. When the fastener 410 is locked, the fastener 410 resists shear forces from the patient's finger being pulled out.

[0055] 36, the finger trap 400 includes a tensioning mechanism 412 extending therefrom. The tensioning mechanism increases or decreases the tension in the finger trap 400. In the illustrated embodiment, the tensioning mechanism 412 is a crimped ball chain. The crimped ball chain is wrapped around the length of flexible material 402 at or near the first end 404. The rack 203 includes a collar 414 extending therefrom. The collar 414 has a ball chain 416 extending therefrom. The ball chain 416 is a chain made up of a series of spaced apart beads 418. The ball chain 416 terminates in a hook 420 for attachment to the towing tower 100. The towing tower 100 applies tension against the hook 420 and a user can increase and decrease the tension by displacing the ball chain 416 on the rack 203 with the desired tension.

[0056] 37 is a perspective view of a finger trap 400 attached to a tow tower 100, according to one embodiment. In the embodiment shown in FIG. 37, the finger trap 400 features a releasable cable tie 422 that allows a surgeon to tighten or loosen the finger trap 400 on a patient's finger. The finger traps 400 incorporate an adjustable cable tie 422, making these finger traps one-size-fits-all. Instead of relying on a number of different finger trap sizes to precisely size a particular length of flexible material 402 to a patient's finger, the cable tie 422 can be tightened to begin holding the finger with the particular length of flexible material 402.

[0057] Another advantage of the finger trap 400 shown in FIG. 37 is that the cable tie 422 can be loosened (non-destructively) if the finger trap 400 needs to be removed and placed on another finger or thumb. A finger trap that traditionally works on a patient's index or ring finger is unlikely to work on the thumb or little finger. This can lead to a scenario where the surgeon must use an oversized finger trap to at least ensure a good fit on all of the patient's fingers. This requires the surgeon to compensate for the larger size by taping and securing the finger trap to the smaller finger. Additionally, the surgeon will have to adjust the traction settings from the traction tower 100 more frequently as the finger trap will slip out (due to being too large) resulting in a loss of traction.

[0058] An additional advantage to the finger trap 400 configuration shown in Fig. 37 is that the adjustable cable tie 422 does not directly contact the patient's finger. The cable tie 422 penetrates only a single layer (e.g., doubled over a braided hose) of the length of flexible material 402. This ensures that when traction is applied, the length of flexible material 402 engages the entire circumference of the finger, instead of where the cable tie 422 tightens, so that it acts to distribute the traction force across the finger.
