Description

[0001] This application is a divisional application of an application with an application date of June 5, 2020, application number 202080049298.9 (international application number PCT / US2020 / 036376), and invention name “Traction tower collector and finger collector system”.

[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to and the benefit of U.S. Provisional Patent Application No. 62 / 871,146, filed on July 7, 2019, entitled “Traction Tower Trap and FingerTrap System,” and U.S. Provisional Patent Application No. 62 / 930,115, filed on November 4, 2019, entitled “Traction Tower Scale,” and is related to PCT Application PCT / US20 / 16170, filed on January 31, 2020, entitled “Wrist Traction Tower,” the entire contents of which are incorporated herein by reference. Background Art 1. Technical Field

[0004] The present invention relates to orthopedic medical procedure positioning devices / systems, and more particularly to a wrist traction tower catcher and finger catcher system.

[0005] 2. Related technologies

[0006] For example, during arthroscopic surgery of the wrist, the surgeon uses traction to create enough space in the wrist joint to properly and effectively use the arthroscope and other related instruments. Conventional traction towers are often used to create this traction required for arthroscopic wrist surgery, radiographic procedures, and other related medical procedures. Straps and finger catchers are used with traction towers to help position and transfer the patient's arm for orthopedic hand and wrist surgery. Straps provide a non-invasive method for securing the patient's forearm and biceps to the traction tower. The finger catcher retains a non-invasive method for securing the patient's fingers. However, conventional traction tower straps and finger catchers are limited in their ability to accommodate a variety of individual patient sizes and are difficult to tighten and release from each patient.

[0007] Therefore, there is a need for easily adjustable and releasable traction tower straps and finger catchers.

Summary of the invention

[0009] Embodiments of the present invention relate to a wrist traction tower and associated traction tower scales. Embodiments of the wrist traction tower relate to a system having multiple parts, one or more of which are configured, attached, positioned and / or structured to move (e.g., slide, telescope, rotate, 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) that can accommodate various lengths and sizes of patient arms while providing sufficient space for practitioners and their corresponding equipment to perform surgical operations, radiographic procedures, and other related medical procedures. Elements of the traction tower system of the embodiment can be made of aluminum, stainless steel, brass, and plastic (PEEK).

[0010] According to one aspect, the present invention is a traction tower assembly. The traction tower assembly may include a first tower having a first side surface and a second tower having a second side surface positioned adjacent to the first side surface, wherein the second tower is movable relative to the first tower in a first direction and in a second direction; and an elongated arm assembly attached to and extending from the tower assembly. A traction tower scale may also be part of an embodiment of the present invention.

[0011] Embodiments of the present invention contemplate that, in a preferred embodiment, when the height of the upper tower and connecting arm assembly is positioned relative to the lower tower, the wrist joint of an individual patient should be approximately 1 inch above the rotational joint (as identified below). This allows a medical practitioner to, for example, x-ray the wrist while keeping the wrist attached to the traction tower. If metal is too close to the wrist joint, it may affect the x-ray image.

[0012] These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Aspects of the present invention and certain features, advantages and details thereof are explained more fully below with reference to the non-limiting examples shown in the accompanying drawings. Descriptions of known structures are omitted so as not to unnecessarily obscure the present invention in detail. However, it should be understood that the detailed description and specific non-limiting examples, although indicating aspects of the present invention, are given only in an illustrative manner, rather than in a limiting manner. Various substitutions, modifications, additions and / or arrangements within the spirit and / or scope of the basic concepts of the present invention will be apparent to those skilled in the art in light of this disclosure.

[0062] Referring now to the drawings, wherein like reference numerals refer to like parts throughout, Figure 1 An exploded perspective schematic diagram of a traction tower 100 is shown according to one embodiment. Figure 2 and Figure 3 According to an implementation scheme Figure 11 is a perspective schematic diagram of an assembly of a traction tower 100. As shown, the traction tower 100 includes a base plate 1, a tower assembly, and an arm assembly. The tower assembly is shown as having multiple parts assembled together: a lower tower 2 and an upper tower 3, and wherein the upper tower 3 is movable relative to the lower tower 2 (as further discussed below). The lower tower 2 can be removably fixed to the base plate 1 (via any attachment device 15, including clips, keyed slides and locking mechanisms, nuts and bolts, etc., as should be understood by a person of ordinary skill in the art in conjunction with the present disclosure). In addition, the lower tower 2 can include a nail 2-2, which is biased in a downward (protruding from the bottom surface of the lower tower 2) direction via a spring (not shown) positioned in the lower tower 2. The nail 2-2 can be lifted by sliding the button 2-1 and is completely positioned in the lower tower 2. The nail 2-2 can be assembled into a hole formed in the base plate 1 (not shown), and then the lower tower can be rotated (counterclockwise or counterclockwise) to help lock the lower tower 2 to the base plate 1. According to one embodiment, all other elements / portions of the traction tower 100 may, but need not, be movable relative to at least one other element / portion of the traction tower 100 .

[0063] Still refer to Figures 1 to 3 , the lower tower 2 is L-shaped and is configured to fit tightly with the upper tower 3, as shown. The tower assembly may include additional pieces and may include multiple shapes, as long as the pieces fit together in a tight arrangement and the overall movement and locking functionality is similar to or remains the same as described herein. The tower assembly components (here, the lower tower 2 and the upper tower 3) can be secured / locked together by a locking knob 4. The rod 4-1 of the locking knob 4 can be positioned to pass through a transverse hole located in each of the lower tower 2 and the upper tower 3, and the knob end can be rotated to secure each tower component together (as should be understood by those skilled in the art in conjunction with a review of this disclosure). The hole in the upper tower 3 is a hole (not shown) that is shaped to tightly fit, engage and secure the rod of the locking knob 4 when the knob end is rotated in the appropriate direction (and disengage and release from the hole in the upper tower when the knob is rotated in the opposite direction). The hole 2-3 in the lower tower 2 is elongated upward and downward (in Fig. 9100 ) to allow upward and downward movement of the upper tower 3 relative to the lower tower 2, wherein the upper tower 3 can be resecured to the lower tower 2 by using a locking knob 4 (as described herein, and as will be understood by one of ordinary skill in the art in conjunction with a review of this disclosure). According to an additional embodiment, the lower tower 2 may include different or additional elongated holes to allow relative movement of the upper tower 3 relative to the lower tower 2 in a diagonal direction, a horizontal direction, or other directions at an angle to the vertical direction B---B when assembled. According to an alternative embodiment, the types of holes may be reversed between the upper tower 3 and the lower tower 2. The upper tower 3 may also include a hole or through hole 14 (longitudinally shaped or otherwise) that may accommodate a strap to hold the patient's forearm to the traction tower 100. The upper tower 3 also includes an alignment pin 3-3 that is configured to fit into a corresponding elongated hole (upward and downward, not shown) in the lower tower 2. The alignment pin 3 - 3 acts in conjunction with the rod 4 - 1 to facilitate alignment of the upper tower 3 relative to the lower tower 2 and prevent unwanted movement / rotation of the upper tower 3 relative to the lower tower 2 when the relative height of the upper tower 3 is adjusted relative to the lower tower 2 .

[0064] Continue to refer Figures 1 to 3, the revolute joint 5 connects the tower assembly to the arm assembly. The rod 13 of the revolute joint 5 can be positioned and rotated in the upper tower 3 (as shown, positioned to pass through the top surface 3-1 of the upper tower 3, and as further discussed below). The top surface 3-1 of the upper tower is configured to extend along a plane that is angled with the bottom surface 3-2 and / or with the plane A---A of the bottom plate 1 when assembled. Alternatively, the top surface 3-1 can extend along a plane parallel to the plane A---A of the bottom plate 1. The first end of the lower arm 6 includes a slotted base end 12 that can be removably positioned, rotated and locked in the head 5-1 of the revolute joint 5 (as further discussed below). The lower arm 6 extends away from the slotted base end 12 and the elongated lower end 6-1 to a curved portion 11 of the lower arm 6, which extends to the elongated upper end 6-2 of the lower arm 6. The upper end 6-2 of the lower arm 6 extends at a certain angle (which can be substantially perpendicular to any angle perpendicular to vertical, including 45 degrees) to the axis of the elongated lower end 6-1. The elongated lower end 7-1 of the upper arm 7 may be, but need not be, solid, fitted within and telescopically movable within the elongated upper end 6-2 of the lower arm 6 formed as a tube. 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 located 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 (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, the at least one side faces the protrusion or tooth of the lever 8). When the lever 8 is actuated in a first direction, thereby positioning the protrusion or tooth between one of a pair of ridges 7-4, the upper arm 7 is fixed / secured / locked relative to the lower arm 6. When the lever 8 is actuated in the second direction, the upper arm 7 is released from its fixed / secured / locked position and is free to move relative to the lower arm 6 (e.g., further within or outside the lower arm 6). According to an alternative embodiment, the upper arm 7 may be tubular in structure, and the lower arm 6 may (but need not be) be solid / non-tubular and contain ridges (substantially similar to the lower arm 6). Figure 1 The lever arm 8 may be any type of actuator, including a linear slide, a circular actuator, a switch, etc. (as will be appreciated by one of ordinary skill in the art in conjunction with a review of this disclosure).

[0065] The elongated lower end 7-1 of the upper arm 7 extends away 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 is angled with respect to the axis of the elongated lower end 7-1 (which may be any angle substantially perpendicular to vertical, including 45 degrees) and extends in substantially the same direction as the elongated lower end 6-1 of the lower arm 6 (and may, but need not, extend in a plane parallel or substantially parallel thereto; as shown, the elongated lower end 6-1 of the lower arm 6 points slightly more in a relatively downward direction than the elongated upper end 7-3 of the upper arm 7, which is shown extending in a plane parallel or substantially parallel to plane A---A). The elongated upper end 7-3 of the upper arm 7 includes a through hole 7-5 configured to facilitate securing a traction tower scale (embodiments of a traction tower scale and its attachment to a traction tower are discussed further below) thereto.

[0066] As discussed above, there are several structural features and configurations that allow the traction tower 100 to be designed as an overall size to fit an individual patient. In addition, as the height of the upper tower 3 is adjusted (as described below with respect to Figures 4 to 5 As described above), the forearm strap position 14 will move with it and always be relatively close to the patient's wrist (the closer to the wrist, the better the strap control). If the strap is located in a fixed position, it will not be suitable for different patient sizes.

[0067] Go to Figures 4 to 5 , providing according to one embodiment Figure 1 A close-up perspective schematic diagram of the lower portion of the traction tower 100 is shown. Figures 4 to 5 The diagram illustrates the movement of upper tower 3 relative to lower tower 2 to accommodate various individual patient forearm sizes, and the structural features that permit such movement. Figure 4 The upper tower 3 is shown to be at the lowest position relative to the lower tower 2, and Figure 5 It is shown that the upper tower 3 is in the highest position relative to the lower tower 2 .

[0068] refer to Figure 4 , the upper tower 3 is shown as fitting tightly within the outline of the lower tower 2 in the lowest position of the upper tower 3. As shown, the upper tower 3 and the lower tower 2 are held together by the locking knob 4 (as discussed above). An interlockable wave / sawtooth pattern 16 may also be provided on each corresponding lateral surface of the upper tower 3 and the lower tower 2 to help lock the upper tower 3 and the lower tower 2 together. The wave / sawtooth pattern 16 may cover the entirety of each corresponding lateral surface of the upper tower 3 and the lower tower 2, or a portion that is less than the entirety of each corresponding surface. In addition, as discussed above, upward adjustment of the upper tower 3 is achieved by: (1) loosening the locking knob 4 and the connection between the upper tower 3 and the lower tower 2; (2) removing the knob 4 from the elongated hole 2-1 (not shown) and the upper tower 3; Figure 4The position shown moves upward to Figure 5 and (3) as a result of the upper tower 3 moving in the upward direction along arrow C, many other elements of the arm assembly including positionable through-hole 14, swivel joint 5, and a strap for the patient's arm (not shown) move in the upward direction relative to lower tower 2. To move upper tower 3 in the opposite direction, the same actions may be performed (i.e., starting with loosening locking knob 4, moving locking knob 4 and upper tower 3 in the opposite direction, etc.).

[0069] As discussed above, the top surface 3-1 of the upper tower is configured to extend along a plane that is positioned at an angle to the plane A---A of the base plate 1 when assembled (see Figure 1 ). The rotary joint 5 being attached to the top portion of the upper tower 3 comprises a rotation axis A1 extending at an angle to the straight upward and downward vertical axis - see Figure 1 By positioning the rotary joint 5, which houses a portion of the lower arm 6, at an angle to the angled rotation axis A1 (see e.g. Figure 6 , which shows that by angling the rotary joint 5 located on the upper tower 3 with its rod 13 located within the upper tower), the rotation of the rotary joint 5 and the arm assembly (further described below) will not displace the point at which the traction force is generated (as will be understood by those of ordinary skill in the art in conjunction with a review of this disclosure). This means that the arm assembly can be as Figures 7 and 8 The patient's arm can be moved as shown without losing traction in the patient's arm or its position.

[0070] Go to Figure 7 and Figure 8 , the top view and the perspective view show the range of rotation of the rotary joint 5 (and therefore the arm assembly) of the traction tower 100 about the rotation axis A1. The rotation D of the rotary joint 5 / arm assembly about the rotation axis A1 (see, for example, Figure 6 ) can be incremented and locked / unlocked by a slotted / toothed implementation as shown and described with respect to the additional rotational functionality (see also with respect to FIG. 18D to FIG. 18E ), may be non-incremental when locked / unlocked by frictional engagement, or may be locked / unlocked by other known locking / unlocking mechanisms (as will be appreciated by one of ordinary skill in the art in conjunction with a review of this disclosure). The range of rotation is illustrated by the shaded (transparent) arm assembly structure 20, which is positioned about a starting or zero position illustrated by the solid arm assembly structure 30. The position of the screw (not shown) holding the traction scale at 7-5 remains consistent despite the rotation of the rest of the arm assembly. Figure 8As shown, regardless of the rotational position of the arm assembly, most of the arm assembly is offset from the patient's arm when in use, which creates sufficient space for surgical instruments. In other words, this structural configuration and related functions allow the practitioner 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 because if the practitioner needs more space for medical instruments around the outside of the wrist joint, the practitioner can just rotate the arm assembly to the back of the arm. Another use of this structural feature includes allowing the practitioner to manipulate the arm assembly so that the C-arm (x-ray machine) is in the appropriate position to take x-rays while the wrist maintains traction.

[0071] Go to Fig. 9 , shows a close-up partial cutaway perspective view of the lower portion of the traction tower 100 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 rotary joint 5 is shown. In particular, as Fig.10 and Fig.11 As shown, the slots / teeth formed on the slotted base end 12 allow incremental rotation of the arm assembly about the second rotation axis E---E. The primary purpose of the elongated lower end 6-1 of the lower arm 6 rotating about the second rotation axis E---E is to allow the practitioner to control the angle of the patient's wrist during use by holding the patient's forearm vertical and pulling the hand at an angle (or vertical) to the elongated axis positioned through the patient's forearm, as will be understood by one of ordinary skill in the art in conjunction with a review of this disclosure. To enable the arm assembly to rotate about the second rotation axis E---E, the button 5-2 can be pushed (the force applied to the button 5-2 is opposite to the spring biasing force) to overcome the biasing force of the spring (not shown) applied upwardly to the button housing 5-3 in the direction of the button 5-2, thereby removing the locking tooth 5-4 from the position positioned between the two corresponding slots / teeth of the slotted base end 12. When the desired position of the arm assembly is reached, the user's force on button 5-2 can be removed and the arm assembly can be locked in the desired position by the described interlocking mechanism (the biasing force applied by the spring pushes the locking tooth 5-4 between the other two slots / teeth of the slotted base end 12).

[0072] Go to Fig.10 and Fig.11 , a perspective schematic diagram shows the range of rotation of the elongated lower end 6-1 of the lower arm 6 (and therefore the arm assembly) of the traction tower 100 about the rotation axis E---E. The rotation F of the elongated lower end 6-1 of the lower arm 6 about the rotation axis E---E can be incremented and locked / unlocked by a slotted / toothed embodiment, as described with respect to Fig. 9As shown and described, it may be non-incremental when locked / unlocked by frictional engagement, or may be locked / unlocked by other known locking / unlocking mechanisms (as will be understood by one of ordinary skill in the art in conjunction with a review of this disclosure). An example of a range of rotation for wrist angle control is shown by the shadow (transparent) arm assembly structure 20 positioned about a starting position or zero position shown by the solid arm assembly structure 30.

[0073] refer to Fig.12 , a perspective schematic diagram of a traction tower 100 having a lever 8 and ridge 7-4 engagement structure and resulting functionality according to one embodiment is shown in a partially transparent view. In short, 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 another adjustment point to respond to a wide variety of individual patient arm sizes. Fig.12 The adjustment mechanism shown in comprises a ratchet mechanism for quickly adjusting the height via actuating the lever 8 to the position end 8-1 within a selected / specific notch formed in the upper arm 7 at 7-4.

[0074] Figures 13 to 14B A traction tower scale 200 is shown according to one embodiment. Fig.13 , a perspective photographic representation of a traction tower 100 and a traction tower scale 200 is shown. The traction tower 200 includes, but is not limited to, a tubular body 211 that is attached to the distal end of the upper end 7-3 of the upper arm 7 of the traction tower 100 (via welding, screws, nuts and bolts, or other known attachment means as should be understood by those skilled in the art in conjunction with a review of this disclosure). The body 211 is configured to contain a knob 209, which is followed by a spring (not shown) positioned through a top portion of the body 211 and attached to the spring. Attached to the bottom end of the spring is a rod / screw 213 that is partially positioned within the body 211 and a portion of which protrudes outside the bottom end of the body 211. The bottom end of the rod / screw 213 includes a hole through which a clip 207 is received. The other end of the clip 207 is attached to a hole formed in or on the rack 203. The rack is shown as having two finger catches 201 attached thereto (but may include one or more than two) for securing the patient's fingers and applying traction.

[0075] Go to FIG. 14A to FIG. 14B, shows a perspective schematic diagram of a traction tower scale 200 according to one embodiment. The rack 203 (to which the finger catcher 201 is attached) is directly connected to the knob 209 by a rod / screw 213 (the rod / screw can be any type of connecting element that can perform the function of the rod / screw 213 described herein, and is not necessarily a rod or a screw). In the "resting" pre-use state (not attached to the patient's finger, or at least not receiving force from the patient's finger), the knob 209 is biased in an upward direction (see arrow A) by a spring located within the body (the spring can be any type of spring, including a helical spring with a known biasing force, as will be understood by one of ordinary skill in the art in conjunction with a review of this disclosure). When a force is applied to the spring in a downward direction (see arrow B) by the weight of the patient's hand / arm (from the finger catcher to the rod / screw 213, to the spring, and to the knob 209), the knob 209 (including its rod) will be pulled further into the body 211 of the scale in a downward direction. The stem of the knob 209 may include a visual indicator (e.g., a line or other marking) that can be used to indicate an estimated amount of traction being used. This can be done by observing where the visual indicator is located in the viewing window 211-2, and the position can match the groove indicating the traction amount number 211-1. The traction measurement unit is pounds. However, the preferred embodiment uses 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.

[0076] Figures 15 to 26 A traction tower 100' is shown in conjunction with an alternative embodiment. This alternative embodiment of the traction tower 100' is similar in many respects to the above-described traction tower 100'. Figures 1 to 12 The following description of the elements / components of the traction tower 100' is therefore primarily limited to alternative / different aspects (such as the upper tower 3' and the swivel joint 5'). If a structural element and its resulting (single or common) function is not discussed, but has been illustrated and / or discussed above, the structure and associated functionality are the same as described above with respect to Figures 1 to 12 The same discussion applies to this section (similarly, regarding Figures 13 to 14B The discussion of the traction tower scale 200 provided in is equally applicable below with respect to the traction tower 200 shown as part of the traction tower 100').

[0077] Go to Fig.15 , shows an exploded perspective schematic diagram of a traction tower 100 ′ according to an alternative embodiment. Fig.15 Similar to Figure 1 , in addition to adding traction tower 200 (about Figures 13 to 14B described) and the alternative embodiments of the upper tower 3' and the rotary joint 5'. Fig.16 and Fig.17According to an alternative embodiment Fig.15 The traction tower 100' is shown in a perspective view of an assembly, and is similar to Figure 2 and Figure 3 .

[0078] Fig.18A is a close-up, partially cut-away perspective view of the lower portion of a traction tower 100' according to an alternative embodiment. Figure 1 As discussed, the upper tower 3' includes an alignment pin 3-3 configured to fit into a corresponding elongated hole / slot 2-3 in the lower tower 2. The alignment pin 3-3 helps the user to easily position the upper tower 3' on the lower tower 2 before installing the tower locking knob 4. It is also ensured that the upper tower 3' remains vertical in the event / time when the user adjusts the height of the upper tower 3' because there are two pins / rods in the slot 2-3 of the lower tower (the pin 3-3 from the upper tower 3' and the rod / stem 4-1 from the tower locking knob 4). In this way, if the height of the upper tower 3' is adjusted after the complete tower is assembled, there is no risk that the entire upper portion (arm assembly) of the tower 100' will rotate downward and turn when the tower locking knob 4 is loosened. In this embodiment, height adjustment can be completed with the tower locking knob 4 loosened and not completely removed from the lower tower / upper tower.

[0079] Go to FIG. 18B to FIG. 18C , showing a close-up transparent perspective view and a close-up stereoscopic view, respectively, of the lower portion of a traction tower 100' according to an alternative embodiment. The lower tower 2 includes a sliding button 2-1 attached to a locking pin 2-2. A spring 2-4 biases the sliding button 2-1 and the pin 2-2 in a downward direction, which can be overcome by a user sliding the button 2-1 to move the pin 2-2 upward within the body of the lower tower 2. The purpose of the pin 2-2 and the attachment means 15 (here a key locking feature) is to lock the lower tower 2 into the base plate 1 when it is installed and to ensure that it does not move until the tower 100' is ready for removal. It also allows the user to quickly assemble and passively lock the tower 100' in place when assembling it (because the peg 2-2 is spring biased to the downward position, the slider button 2-1 does not have to be actuated when assembling - the lower tower 2 can just be pushed flush to the base 1 and twisted so that the peg 2-2 drops into the base hole 1 when in the right rotated position. The key locking feature 15 is located on the base key hole 1-1 and also helps to lock the lower tower 2 to the base 1 after the twisting action.

[0080] Go to Fig.18D, shows a close-up, partially cut-away perspective view of the lower portion of a traction tower 100' according to an alternative embodiment. The slider button 5-7 is shown connected to a locking pin 5-8, which is biased upward into a hole 5-10 formed in the body of the rotational joint 5 via a spring 5-6. In order to release the joint and freely rotate the joint about the rotational axis A1, the user can push the slider button 5-7 in a downward direction to remove the locking pin from the hole 5-10 until the desired rotational position is reached. The button can then be released and the spring 5-6 can move the locking pin 5-8 into another hole 5-10 (see Fig.18E ).

[0081] Go to Fig.19 and Fig. 20 , according to an alternative embodiment Fig.15 A close-up perspective schematic diagram of the lower portion of the traction tower 100' is shown. Fig.19 and Fig. 20 Similar to Figures 4 to 5 , except for the structural differences noted herein and above regarding the discussion of the swivel joint 5' and upper tower 3'. However, the same movement of the upper tower 3 relative to the lower tower 2 and the structural features that allow such movement to accommodate a variety of individual patient forearm sizes are present in the upper tower 3'. Fig.19 The upper tower 3' is shown to be in the lowest position relative to the lower tower 2, and Fig. 20 The upper tower 3' is shown in a relatively uppermost position relative to the lower tower 2. The holes shown other than hole 14 show where metal has been removed for weight saving and thermal management purposes.

[0082] refer to Fig.21 , according to an alternative embodiment Fig.15 A perspective view of a traction tower 100' is shown. Figure 6 , Fig.21 The axis of rotation A1 formed by angling the rotary joint 5' on the upper tower 3' and its rod 13 located in the upper tower is shown.

[0083] Go to Fig. 22 and Fig.23 , a perspective schematic diagram and a top schematic diagram are provided showing the rotation range of the rotary joint 5 (and therefore the arm assembly) of the traction tower 100 ′ about the rotation axis A1 . Fig. 22 and Fig.23 Similar to Fig. 22 and Fig.23 .

[0084] refer to Fig.24 , shows a close-up partial cut-away perspective view of a lower portion of a traction tower 100 ′ according to one embodiment. Fig.24 Similar to Fig. 9 , and the elements function in a similar manner, even though there are some structural differences with respect to the swivel joint 5 ′ and upper tower 3 ′ discussed above.

[0085] refer to Fig.25 , a perspective schematic diagram shows the range of rotation of the elongated lower end portion 6 - 1 of the lower arm 6 (and therefore the arm assembly) of the traction tower 100 about the rotation axis E—E. Fig.25 Similar to Fig.10 and Fig.11 .

[0086] Go to Fig.26 , a perspective schematic diagram of a traction tower 100 ′ having a height adjustment mechanism including a lever 8 and ridge 7 - 4 engagement structure and the resulting functionality according to an alternative embodiment is shown in a partially transparent view. Fig.26 Similar to Fig.12 .

[0087] Go to Fig. 27 , shows a perspective photographic representation of a traction tower 100 ′ according to an alternative embodiment. Fig. 27 The placement of the patient's arm relative to the traction tower assembly 100' is shown.

[0088] Reference now Fig.28A and Fig.28B , a top view photographic representation of the strap 300 according to two embodiments is shown. The strap 300 is designed to be quickly connected to the traction tower 100 and to easily adjust the length of the strap 300 to accommodate a variety of patient sizes. Although the strap 300 can be used to secure the patient's arm in any position, FIG. 28A to FIG. 28B The embodiment of the strap 300 in is preferably placed around the patient's biceps. FIG. 28A to FIG. 28B The strap 300 in FIG. 1 includes a length of material 302 for wrapping around a patient's arm (e.g., bicep). For example, the length of material 302 may be constructed of any non-flexible material, such as polyester. The length of material 302 must be non-flexible in order to prevent stretching and loosening around the patient's arm. The length of material 302 should also be constructed of a material that is non-irritating to the skin while having sufficient friction to allow the length of material 302 to lock when in use and slide along itself when released.

[0089] Still reference FIG. 28A to FIG. 28B , for patient comfort and safety, a length of material 302 includes a pad 304. Pad 304 is attached to at least a portion of the length of material 302. Fig.28A In the embodiment of FIG. 5 , the width of the pad 304 is 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. Fig.28AIn one embodiment, the pad 304 is attached to a length of material 302 with an adhesive or with a connector (such as a hook and loop connector) to allow the pad 304 to be easily replaced.

[0090] exist Fig.28B In the embodiment shown in FIG. 3 , pad 304 extends around at least a portion of a length of material 302 . Fig.28B The strap 300 in the embodiment is preferably a biceps strap, which is used to hold the patient's biceps on the bottom plate 1 of the traction tower 100 (hereinafter, the bottom plate, the traction tower and its components may be any of the aforementioned embodiments). Fig.28B 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 a length of material 302, or it may be removable (e.g., via a seam along a length of pad 304, which may be attached with an adhesive or connector). The 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 movement of the patient's arm while maintaining the comfort of the pad 304.

[0091] refer to Fig.28A and Fig.28B In both cases, the length of material 302 includes one or more adjustment mechanisms 306. The purpose of the adjustment mechanism 306 is to tighten the strap 300 (i.e., adjust the length of strap 300) and secure arms of various sizes to the floor 1 of the traction tower 100. In the depicted embodiment, the adjustment mechanism 306 is a buckle. Specifically, FIG. 28A to FIG. 28B A length of material 302 in FIG. 3 has two buckles 306 , one on each side of pad 304 .

[0092] exist FIG. 28A to FIG. 28B , a length of material 302 is shown woven through a buckle 306, and the buckle 306 is substantially equidistant from the pad 304. FIG. 28A to FIG. 28B As shown in FIG. 3 , a first end 308 of a length of material 302 extends from a first buckle 306 toward a pad 304, and a second end 310 of a length of material 302 extends from a second buckle 306 toward a pad 304. FIG. 29A to FIG. 29B As shown in FIG. 1 , in use, an opening 312 having a first diameter is created between the base plate 1 of the traction tower 100 and a 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 tensioning the first end 308 and the second end 310 of the length of material 302 through the buckle 306.

[0093] like FIG. 29A to FIG. 29B As shown in , the first and second buckles 306 slide into the slots 424, 426 of the base plate 1 and can be moved toward the center 428 of the base plate 1 to accommodate the patient's arm size. In the depicted embodiment, the slots 424, 426 are located on opposite sides of the base plate 1. FIG. 29A to FIG. 29B 4, 426 are aligned such that the central axes of the slots 424, 426 are the same. The benefit of this connection is that the sliding buckle 306 within the base plate 1 acts as an additional adjustment mechanism. In particular, as the buckle 306 of the strap 300 is moved closer to the patient's biceps, a certain length of the strap 300 can be further tensioned, thereby minimizing the opening 312 and allowing the strap 300 to more effectively limit movement. When the strap 300 is a biceps strap, it is intended to limit the vertical movement of the biceps due to the traction applied to the wrist and the lateral movement caused when the surgeon applies force to the wrist during surgery. FIG. 29A to FIG. 29B The strap 300 in FIG. 1 is a forearm strap, which is FIG. 28A to FIG. 28B In one embodiment, the forearm strap 300 ( FIG. 29A to FIG. 29B ) includes a 2 inch wide webbing for holding the patient's forearm and two plastic buckles 306 that allow it to be connected to the upper tower part 3 of the traction tower 100 and adjust a certain length of the strap 300.

[0094] FIG. 29A to FIG. 29B One major benefit of the forearm strap 300 shown in FIG. 1 is that it is connected to the upper tower component 3 of the traction tower 100. Since the upper tower 3 of the traction tower 100 can be positioned higher or lower based on the patient's anatomy, the forearm strap 300 will always be positioned close to the patient's wrist. The closer the strap 300 is to the lateral forces applied by the surgeon during surgery, the more effective it is in preventing lateral movement of the wrist.

[0095] refer to FIG. 30A to FIG. 30C , which shows schematic front, side and rear views of a buckle 306 according to one embodiment. FIG. 30A to FIG. 30C The buckle 306 shown in FIG. 1 is easy to adjust and has a high locking strength. Fig. 30B In the side view shown in FIG. 3 , buckle 306 has a circular profile. In other words, top surface 314 ( Fig. 30A ) and bottom surface 316 ( Fig. 30C ) is curved so that the buckle 306 fits comfortably against the patient's arm and accommodates arms of different sizes well.

[0096] refer to Fig. 30A and Fig. 30B, buckle 306 has a rounded top portion 318 connected to a rectangular adjustable section 320. Adjustable section 320 is connected to a generally rectangular base portion 322 with one or more connectors 323 extending therefrom. A side view of buckle 306 shows that the side profile of buckle 306 is rounded from top portion 318 to base portion 322. Fig. 30C 3, the bottom surface 316 of the buckle 306 has a ridge 324 extending around the perimeter of the top portion 318. The ridge 324 is designed to act as an ergonomic thumb ridge to allow the user to increase the grip of the buckle 306 to easily release the strap 300 around the patient's arm. The increased grip is particularly beneficial when the user manipulates the strap 300 with wet gloves.

[0097] like Fig. 30C As shown in FIG, the bottom surface 316 of the buckle 306 has one or more flanges 326 extending from the base portion 322. Fig. 30C In the embodiment shown in FIG, there are two generally parallel flanges 326 extending from the base portion 322. Fig. 30B As shown in the side profile of the buckle 306 in FIG. 1 , the flange 326 is triangular. When the user slides the buckle 306 into the floor 1 of the traction tower 100, the flange 326 guides the buckle 306. The flange 326 adds rigidity to the base portion 322 of the buckle 306 that bears most of the force.

[0098] refer to Fig. 30A and Fig. 30C , the adjustable section 320 of the buckle 306 includes teeth 328. The teeth 328 extend across the adjustable section 320 to increase the strength of the buckle 306 when tightened. The teeth 328 provide an increased grip on a length of material 302 and prevent slippage when tightened.

[0099] Back to Fig. 30B , the overall profile of the buckle 306 is thin. This allows the buckle 306 to also cover the bottom of the bicep. The buckle 306 has an interference angle that extends along the outer edge 330 of the prong 332 that extends across the adjustable section 320. Fig. 30B The interference angle in the buckle 306 is steep, ranging from 0 to 45 degrees. The steep interference angle provides high friction between the length of material 302 when in use and easy release when the first end 308 or the second end 310 of the length of material 302 is pulled down away from the patient's arm.

[0100] Reference now Fig.31A and Fig.31B, shows a front and perspective schematic view 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 traction tower 100. The forearm buckle mount 334 includes a rectangular cylindrical section 336 with one or more columns 338 extending across it. In the depicted embodiment, the cylindrical section 336 has at least two spaced apart columns 338 extending across it. The forearm buckle mount 334 includes an outer flange 340 connected to the cylindrical section 336. The outer flange 340 includes a slot 342. The slot 342 extends along an axis perpendicular to the axis extending through each column 338. The slot 342 is asymmetric to allow only the correct insertion orientation while preventing incorrect insertion orientation. The forearm buckle mount 334 promotes free, low-friction rotation of a 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 attaching to the connector 323 of the buckle 306 .

[0101] Go to Figure 32 to Figure 34 , buckle 306 and forearm buckle mount 334 are shown attached to traction tower 100. Fig.32 As shown in FIG. 1 , the outer flange 340 of the forearm buckle mount 334 extends from a first side 430 of the traction tower 100, and the buckle interface 344 of the forearm buckle mount 334 extends from an opposite second side 432 of the traction tower 100. Fig.33 , the buckle 306 can rotate about the buckle interface 344 of the forearm buckle mount 334 relative to the second side 432 of the traction tower 100. The buckle interface 344 has an audible click and tactile feedback to indicate that the connector 323 of the buckle 306 has been attached to the forearm buckle mount 334. Fig.35 The traction tower 100 is shown with the strap 300 attached. The buckle 306 is held in place within the buckle interface 344 during use and easily snaps out when the user is finished using the buckle 306. The same buckle 306 is used as a bicep strap 300 with full rotational usability.

[0102] Now go to Fig.36, a schematic top view of a finger catcher 400 according to one embodiment is shown. The finger catcher 400 has a length of flexible material 402 with a first end 404 and a second end 406. In one embodiment, the length of flexible material 402 is composed of a mesh or woven material. For example, the length of flexible material 402 can be a double layer of mesh material. The length of flexible material 402 is closed at the first end 404 and open at the second end 406. In the depicted embodiment, the length of flexible material 402 is tapered or funnel-shaped, 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 and rounded, and has an internal volume 408 to facilitate finger insertion. In one embodiment, the length of the length of flexible material 402 is approximately six inches in length to accommodate fingers of various sizes.

[0103] Still refer to Fig.36 , a fastener 410 is attached at or near the second end 406 of the finger catcher 400. In the depicted embodiment, the fastener 410 is a hook and loop fastener 410. The fastener 410 is woven through a length of flexible material 402 at at least one location. Specifically, as Fig.36 , the fastener 410 extends through the length of flexible material 402 into the interior volume 408 and backs out 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. With the fastener 410 locked, the fastener 410 resists shear forces from the patient's finger being pulled out.

[0104] Also like Fig.36 As shown in , the finger catcher 400 includes a tensioning mechanism 412 extending therefrom. The tensioning mechanism increases or decreases the tension on the finger catcher 400. In the depicted embodiment, the tensioning mechanism 412 is a curled ball chain. The curled ball chain includes a collar 414 extending around a length of flexible material 402 at or near a first end 404. The collar 414 has a ball chain 416 extending therefrom. The ball chain 416 is a chain consisting of a series of spaced apart beads 418. The ball chain 416 terminates in a hook 420 for attachment to the traction tower 100. The traction tower 100 tensions the hook 420, and the user can increase and decrease the tension by replacing the ball chain 416 in the rack 203 with the desired tension.

[0105] Now go to Fig.37 , shows a perspective photographic representation of a finger catcher 400 attached to a traction tower 100 according to one embodiment. Fig.37In the embodiment shown in FIG, the finger trap 400 has a releasable cable tie 422 that allows the surgeon to tighten and loosen the finger trap 400 on the patient's finger. The finger trap 400 includes an adjustable cable tie 422 to make these finger traps a universal size. Instead of relying on a certain length of flexible material 402 to fit tightly to the patient's finger (requiring several different finger trap sizes), the cable tie 422 can be tightened to activate a certain length of flexible material 402 that holds the finger.

[0106] Fig.37 Another advantage of the finger catcher 400 shown in FIG. 1 is that the cable tie 422 can be released (non-destructively) if the finger catcher 400 needs to be removed and placed on another finger or thumb. Traditionally, a finger catcher that works on a patient's index or ring finger is unlikely to work on a thumb or pinky finger. This can lead to a situation where the surgeon has to use oversized finger catchers to ensure that they at least fit all of the patient's fingers. This requires the surgeon to compensate for the large size by sticking the finger catcher on a smaller finger to try to secure it. Additionally, the surgeon has to adjust the traction setting from the traction tower 100 more frequently because the finger catcher can slip (due to being oversized), resulting in a loss of traction.

[0107] Fig.37 Another benefit of the configuration of the finger catcher 400 shown in FIG. 4 is that the adjustable cable tie 422 never directly contacts the patient's finger. The cable tie 422 only pierces a single layer of the length of flexible material 402 (e.g., doubled over a braided hose). This ensures that the length of flexible material 402 engages the entire circumference of the finger so that when traction is applied, the length of flexible material 402 performs the function of distributing the traction over the entire finger rather than just at the location where the cable tie 422 is tightened.
