[0029] Although the concept of the present invention is susceptible to various modifications and alternative forms, specific exemplary embodiments thereof have been shown in the drawings by way of example and will be described in detail herein. However, it should be understood that it is not intended to limit the concept of the present invention to the specific form disclosed, but on the contrary, the purpose is to cover all modifications, equivalents and substitutes within the spirit and scope of the present invention as defined by the appended claims.

[0030] refer to Figure 1 , the support device 10 includes, for example, an operating table 12 and a limb support unit 14 embodied as a hip traction device. The limb support unit 14 is connected to the foot end 16 of the operating table 12. In the example of use, the limb support unit 14 supports the patient's legs, and the operating table 12 supports the patient's upper body. The limb support unit 14 can be used to apply tension to the patient's legs during surgery. This is also called placing the patient's legs in traction. In hip replacement surgery, it may be necessary to reposition the legs of the patient who is replacing the hip joint during surgery in order to provide better access for the surgeon while keeping the patient's legs in traction. The limb support unit 14 according to the present invention provides the ability to reposition the patient's legs while keeping the legs in traction. The limb support unit 14 is also constructed to apply enough force to the patient's legs during hip traction to pull the hip joint out of the acetabulum (i.e., pull the femoral head out of the acetabulum).

[0031] In the illustrated example, the limb support unit 14 includes an anti-traction unit 18, such as a padded perineum post, and leg supports 22, which each support a boot housing 58. The anti-traction unit 18 is coupled to a fixed position at the foot end 16 of the operating table 12. The leg supports 22 are coupled to the anti-traction unit 18 in a spaced relationship. Figure 1As shown, the movable leg support 50 moves relative to the counter-traction unit 18. The movable leg support 50 includes a joint mount 24, a multi-axial joint 26, and a beam 28. The joint mount 24 is connected to a fixed position of the counter-traction unit 18, while the limb support unit 14 supports a portion of the patient. The multi-axial joint 26 is configured to interconnect the beam 28 with the joint mount 24 so that the beam 28 moves relative to the joint mount 24. The beam 28 is connected to the multi-axial joint 26 and is configured to extend away from the multi-axial joint 26 to support the patient's leg in traction during surgery involving hip traction. The fixed leg support 52 is fixed and supported by the auxiliary rails located on the side of the operating table 12 and the limb support unit 14 to which the counter-traction unit 18 and the multi-axial joint 26 are also connected. The fixed leg support 52 can be separated from the limb support unit 14 and the operating table auxiliary rails; however, when used in surgery, the fixed leg support 52 is fixed.

The instep pad 102 includes a leg engaging portion 132, which is positioned above the leg wrap 130 and is configured to secure the patient's foot within the surgical boot device 100, as described below.

[0035] Reference now Figure 3 , the boot shell 58 includes an inner side 136 and an opposite outer side 138. For reference, the inner side 136 is positioned near the midline of the patient. That is, relative to the hip tractor 10, the inner side 136 is positioned near the centerline of the hip tractor 10. The outer side 138 is positioned away from the midline of the patient. Relative to the hip tractor 10, the outer side 138 is positioned away from the centerline of the hip tractor 10. In some embodiments, the surgical boot device 100 is symmetrical about the centerline between the inner side 136 and the outer side 138. Four strips 140 are connected to the boot shell 58 and extend from the boot shell 58. The four strips 140 include a first inner side strip 142, a first outer side strip 144, a second inner side strip 146 and a second outer side strip 148.

[0036] The proximal end 150 of the first medial strap 142 is attached to the calf portion 106 of the boot shell 58 on the medial side 136. The proximal end 152 of the first lateral strap 144 is also attached to the calf portion 106 of the boot shell 58 on the lateral side 138. Figures 6 to 8 , the boot shell 58 includes a plurality of pivot points 156. The proximal end 150 of the first inner strap 142 and the proximal end 152 of the first outer strap 144 are pinned to respective pivot points 156 to allow the first inner strap 142 and the first outer strap 144 to rotate about respective pivot axes relative to the boot shell 58. The first inner strap 142 and the first outer strap 144 are each embodied as a ladder strap that includes a plurality of ridges 154 to enable the straps to be engaged by a snap ratchet, as described below. In some embodiments, other types of straps are used in place of the ladder straps 142, 144, 146, 148. In the illustrative embodiment, the first inner strap 142 and the first outer strap 144 have substantially equal lengths. It should be understood that in other embodiments, the first inner strap 142 and the first outer strap 144 may have different lengths.

[0037] The proximal end 160 of the second medial strap 146 is attached to the engagement area 112 of the boot shell 58 on the medial side 136. The proximal end 162 of the second lateral strap 148 is also attached to the engagement area 112 of the boot shell 58 on the lateral side 138. Figures 6 to 8 , the proximal end 160 of the second inner strap 146 and the proximal end 162 of the second outer strap 148 are pinned to respective pivot points 156 to allow the second inner strap 146 and the second outer strap 148 to rotate about respective pivot axes relative to the boot shell 58. The second inner strap 146 and the second outer strap 148 are each embodied as a ladder-like strap that includes a plurality of ridges 154 to enable the straps to be engaged by a snap ratchet, as described below. In some embodiments, other straps are contemplated. In the illustrative embodiment, the second inner strap 146 and the second outer strap 148 have substantially equal lengths. It should be understood that in other embodiments, the second inner strap 146 and the second outer strap 148 may have different lengths. In some embodiments, the first inner strap 142, the second inner strap 146, the first outer strap 144, and the second outer strap 148 have substantially equal lengths.

[0038] When it is stated herein that the strips 142, 144, 146, 148 have "substantially" equal lengths, it is intended to encompass lengths that are within + / - 10% of each other. For example, if the length of a strip is 10 inches, a strip that is 9 inches to 11 inches in length is considered to have a length that is substantially equal to the 10 inch strip. That is, 10% of 10 inches is 1 inch. This is merely an arbitrary example and is not intended to imply that any of the strips 142, 144, 146, 148 is 10 inches long, but it is not intended to exclude such a possibility.

[0039] The leg engaging portion 132 of the instep pad 102 is generally hourglass-shaped. Four buckles 170 are provided on the leg engaging portion 132 of the instep pad 102 to connect with corresponding straps 140. The buckles 170 are operable to secure the instep pad 102 against the patient's leg when the patient's leg is positioned within the boot shell 58. The buckles 170 are movable to a released state to allow the instep pad 102 to be completely separated from the four straps 140.

[0040] The first inner buckle 172 is configured to be attached to the first inner strap 142. The first outer buckle 174 is configured to be attached to the first outer strap 144. The first inner buckle 172 and the first outer buckle 174 are respectively embodied as ratchet buckles, and the corresponding first inner ladder strap 142 and the first outer ladder strap 144 are ratcheted by the ratchet buckles. The second inner buckle 176 is configured to be attached to the second inner strap 146. The second outer buckle 178 is configured to be attached to the second outer strap 148. The second inner buckle 176 and the second outer buckle 178 are respectively embodied as ratchet buckles, and the corresponding second inner ladder strap 146 and the second outer ladder strap 148 are ratcheted by the ratchet buckles.

[0041] The first patch 180 is coupled to the leg engaging portion 132 to define a first pocket 182 (eg, Figure 2 172 and the first lateral buckle 174. The first pocket 182 includes an open inner side 184 and an open outer side 186. The distal end 190 of the first inner strap 142 can be inserted into the first pocket 182 through the open inner side 184 of the first pocket 182 to keep the distal end 190 of the first inner strap 142 against the instep pad 102 during surgery. The distal end 192 of the first lateral strap 144 can be inserted into the first pocket 182 through the open outer side 186 of the first pocket 182 to keep the distal end 192 of the first lateral strap 144 against the instep pad 102 during surgery.

[0042] The second patch 200 is coupled to the leg engaging portion 132 to define a second pocket 202 (eg, Figure 2 The second pocket 202 is located between the second inner buckle 176 and the second outer buckle 178.

The distal end 210 of the second inner strap 146 (as shown) Figure 4 The second pocket 202 may be inserted into the second pocket 202 through the open medial side 204 thereof to hold the distal end 210 of the second medial strap 146 against the instep pad 102 during surgery. The distal end 212 of the second lateral strap 148 may be inserted into the second pocket 202 through the open lateral side 206 thereof to hold the distal end 212 of the second lateral strap 148 against the instep pad 102 during surgery.

[0043] refer to Figure 5 and Figure 6 , the boot shell 58 includes a heel receiving opening 220. The heel receiving opening 220 extends completely through the boot shell 58. The heel receiving opening 220 is located between the sole portion 104 and the calf portion 106 of the boot shell 58. That is, the heel receiving opening 220 extends partially through the sole portion 104 of the boot shell 58 and partially through the calf portion 106 of the boot shell 58. The heel receiving opening 220 is configured to receive the patient's heel. Therefore, when the patient's foot is positioned in the boot shell 58, the patient's heel is positioned within the heel receiving opening 220.

[0044] The elastic pad 230 is positioned in the calf portion 106 of the boot shell 58. In some embodiments, the elastic pad 230 is made of silicone rubber. It should be understood that other suitable materials can be used to form the elastic pad 230. In some embodiments, the elastic pad 230 is molded. For example, the elastic pad 230 can be molded to a specific patient's heel. The elastic pad 230 includes a main body portion 232, which is configured to engage the heel area of ​​the patient's foot. The main body portion 232 includes an end region 234 having a U-shaped end edge 236. The U-shaped end edge 236 includes a notch 238, which is configured to receive the calcaneus of the patient's foot. The notch 238 is tapered from the main body portion 232 to the U-shaped end edge 236.

[0045] Reference now Figure 7 and Figure 8 The heel receiving opening 220 is partially defined by a U-shaped edge 222 of the calf portion 106 of the boot shell 58. Figure 6As shown in FIG. 5 , the heel receiving opening 220 is also defined in part by a linear edge 224 of the sole portion 104 of the boot shell 58. The heel receiving opening 220 extends between the U-shaped edge 222 and the linear edge 224.

[0046] The end region 234 of the resilient pad 230 extends into the heel receiving opening 220. The resilient pad 230 includes a U-shaped lip 250 extending along the U-shaped end edge 236 and having a groove 252. In some embodiments, the U-shaped lip 250 is integrally formed with the main body portion 232 of the resilient pad 230. Fig. 9 As shown, the groove 252 is configured to receive the U-shaped edge 222 of the calf portion 106 to attach the resilient pad 230 to the boot shell 58. Fig. 9 The patient's feet are shown without Figure 2 The leg wrap 130 is shown. Fig. 9 The illustrations of the midfoot and calf are intended to include the leg wrap portion 130, but the leg wrap portion 130 may optionally be omitted.

[0047] The calf portion 106 of the boot shell 58 also includes a plug receiving opening 240 spaced apart from the heel receiving opening 220. Figure 8 As shown, the heel receiving opening 220 and the plug receiving opening 240 are both centered about the longitudinal axis 114 of the calf portion 106 of the boot shell 58. The plug receiving opening 240 includes a triangular opening defined by an opening edge 242 having rounded corners 244. It should be understood that in other embodiments, the plug receiving opening 240 may have other shapes.

[0048] The plug 260 extends from the main body portion 232 of the resilient pad 230. In some embodiments, the plug 260 of the resilient pad 230 is formed integrally with the main body portion 232 of the resilient pad 230. In other embodiments, the plug 260 may be formed separately from the main body portion 232 of the resilient pad 230. The peripheral wall 262 of the plug 260 is generally triangular in shape with rounded corners 264. It should be understood that in other embodiments, the plug 260 may have other shapes. The size and shape of the plug 260 are generally adapted for the plug receiving opening 240. The plug 260 is configured to be press-fitted into the plug receiving opening 240 of the boot housing 58 to attach the resilient pad 230 to the boot housing 58. As shown in FIG. Fig. 9 As shown, the peripheral wall 262 includes a recess 266 configured to receive the opening edge 242 of the plug receiving opening 240 of the calf portion 106 to attach the resilient pad 230 to the boot shell 58 .

[0049] During use of the surgical boot device 100, the traction force pulls the calcaneus of the patient's foot into contact with the elastic pad 230 to prevent the heel from lifting. It should be noted that in the presence of the leg wrap 130 on the patient's foot, the calcaneus does not directly contact the elastic pad 230. Instead, the leg wrap 130 is positioned between the calcaneus and the elastic pad 230. In some embodiments, the elastic pad 230 comfortably grips the top of the patient's calcaneus to form a firm support while reducing the risk of pressure injuries. In some embodiments, the leg engaging portion 132 of the instep pad 102 conforms to the top of the patient's ankle and lower tibia. The leg engaging portion 132 of the instep pad 102 has a ratchet buckle 170 at the top and bottom of the pad 102 on the outside and inside of the patient's leg to keep the pad 102 on the center of the patient's leg / foot and generate symmetrical pressure to pull the heel back into the boot shell 58. This pressure forces the heel to be gripped by the elastic pad 230.
