DETAILED DESCRIPTION

[0017] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0019] It should be noted that in actual clinical surgery, such as knee replacement surgery for orthopedic patients, the lower limbs need to be fully disinfected twice before surgery. At present, there are some limb lifting devices that can lift the lower limbs of surgical patients. However, their lifting mechanisms are complex, occupy a lot of surgical space, and are not flexible enough in actual use. In addition, the support pad for lifting the patient's legs has a large contact surface with the surgical patient. During the actual disinfection process, medical staff need to lift it to cooperate with the disinfection, which is very inconvenient in actual use. For this reason, such patients urgently need a more In order to provide a more flexible and practical limb lifter, the present invention provides a limb lifter for skin disinfection in limb surgery, comprising: a frame 10; a support beam 20, which is horizontally arranged and installed on the frame 10; a height adjustment mechanism for adjusting the height of the support beam 20; a support rope 30, both ends of which are installed on the support beam 20 and are equipped to be able to clamp the patient's lower limbs; and a disinfection liquid storage chamber, which is arranged along the extension direction of the support rope 30 and can soak the surface of the support rope 30 with disinfectant.

[0020] In one embodiment, see Figure 1 and Figure 2 The support beam 20 and the frame 10 can be made of metal or engineering plastics to provide greater support stability and avoid being too heavy and inconvenient to move. The frame 10 is movable. During surgery, the limb lifter is transferred to the bed position in the operating room, and the patient's legs are placed on the support rope 30. The height of the support beam 20 is adjusted through the height adjustment mechanism, so that the patient's lower limbs can be raised.

[0021] In one embodiment, see Figure 4 and Figure 6 The supporting rope 30 can be supported by a flexible material to avoid mechanical damage to the patient's lower limb skin as much as possible.

[0022] In one embodiment, disinfectant can be injected into the disinfectant storage chamber through a needle, so that the disinfectant is soaked on the surface of the support rope 30, so that the disinfectant is always present between the patient's lower limbs and the support rope 30.

[0023] In one embodiment, in order to further improve the flexibility of use of the limb lifter, a width adjustment mechanism is further included, and the width adjustment mechanism is configured to be able to adjust the length of the supporting beam 20 .

[0024] In one embodiment, the limb lifter is placed at the head of the operating table, and the supporting beam 20 is placed horizontally above the operating table. The width of the limb lifter can be adjusted according to actual usage requirements to adapt to different models of operating tables.

[0025] Preferably, the supporting rope 30 is in the shape of a parabola with its opening facing upward as a whole, and the distance between the two ends of the supporting rope 30 is adjustable.

[0026] In one embodiment, see Figure 6 The support rope 30 is made of soft silicone material. When the patient's lower limbs are placed on the support rope 30, the support rope 30 presents a parabolic shape with the opening facing upward, and the spacing between the two ends of the support rope 30 is adjustable, so that the upper end opening of the support rope 30 is as large as possible to reduce the contact area between the support rope 30 and the lower limbs as much as possible.

[0027] In one embodiment, see Figure 6 and Figure 7 To ensure that the disinfectant is evenly soaked on the surface of the support rope 30, the support rope 30 is a medium-hole flexible tube, the lumen of the support rope 30 constitutes the disinfectant storage chamber, and the support rope 30 is covered with an infiltrated flexible pad 31, which is connected to the infiltrated flexible pad 31.

[0028] In one embodiment, the impregnated flexible pad 31 may be a highly elastic sponge or a medical veil, which has the function of storing liquid and can absorb the disinfectant in the lumen of the supporting sling 30 onto the impregnated flexible pad 31, so that when the patient's lower limbs are placed on the impregnated flexible pad 31, they can be effectively disinfected. Moreover, the impregnated flexible pad 31 can avoid mechanical damage to the skin of the patient's lower limbs on the one hand, and can also effectively increase the friction with the patient's lower limbs on the other hand, so as to effectively lift the patient's lower limbs.

[0029] In one specific embodiment, see Figure 7 The support rope 30 is also provided with an injection hose 32, and the injection hose 32 is arranged along the extension direction of the support rope 30. A first through hole 321 is provided on the tube wall of the injection hose 32, and the first through hole 321 is connected to the second through hole 33 provided on the support rope 30. The second through holes 33 are arranged at intervals along the length direction of the support rope 30, and the opening of the second through hole 33 also points to the infiltrated flexible pad 31.

[0030] In one embodiment, see Figure 7The injection hose 32 is a flexible silicone tube, and the disinfectant can be injected through the injection hose 32 by a syringe, and the disinfectant enters the tube cavity of the support rope 30 through the first through hole 321 and the second through hole 33, and multiple groups of second through holes 33 are arranged, and the multiple groups of second through holes 33 are arranged in the middle position of the support rope 30 as much as possible. When the patient's lower limbs are placed on the support rope 30, the support rope 30 is deformed by squeezing, so that the disinfectant in the support rope 30 is squeezed through the second through hole 33 to the infiltration flexible pad 31, so that the surface of the infiltration flexible pad 31 is infiltrated with disinfectant, so as to implement disinfection of the contact position of the patient's lower limbs.

[0031] In one specific embodiment, see Figure 4 In order to facilitate the fixation of the two ends of the support rope 30, the two ends of the support rope 30 are respectively provided with a lifting ring 34, and the support beam 20 is provided with a hook 21, and the lifting ring 34 is hung on the hook 21.

[0032] In a specific embodiment, the supporting beam 20 is tubular, the hook 21 is installed on a slider, a pulley 22 is provided on the slider, the pulley 22 is located in the supporting beam 20 and rolls along the length direction, a plurality of groups of limiting holes 23 are provided in the length direction of the supporting beam 20, and a limiting pin 24 is provided in the limiting hole 23, and the limiting pin 24 is used to implement sliding limitation of the pulley 22.

[0033] In one embodiment, see Figure 5 By inserting the limit pin 24 into the limit hole 23, the limit pin 24 is abutted against the pulley 22 to prevent the pulley 22 from rolling in the supporting beam 20, and the two ends of the supporting rope 30 are at the maximum distance as much as possible to increase the opening of the parabola of the supporting rope 30 and reduce the contact area between the supporting rope 30 and the patient's lower limbs.

[0034] Furthermore, in order to adjust the length of the supporting crossbeam 20 so as to flexibly adjust the width of the entire limb lifter, the supporting crossbeam 20 is composed of two unit supporting tubes, and the tube mouths of the unit supporting tubes are inserted into the tube mouths of the adjusting middle tube 25. The insertion and removal positions of the unit supporting tubes in the adjusting middle tube 25 are adjustable, and the adjusting middle tube 25 constitutes the width adjustment mechanism.

[0035] In one embodiment, see Figure 1 and Figure 2 The unit support tube and the adjustment middle tube 25 can be plug-in compatible without locking, so as to facilitate the adjustment of the limb lifter width.

[0036] In one specific embodiment, see Figure 8The frame 10 includes a mobile base 11; a column 12, and the lower end of the column 12 is installed on the mobile base 11; the height adjustment mechanism is used to adjust the length of the column 12, and the supporting beam 20 is installed at the upper end of the column 12.

[0037] In one embodiment, two groups of mobile bases 11 and columns 12 are arranged at both ends of the supporting beam 20 so that the limb lifter forms a stable supporting structure, and each mobile base 11 is provided with at least two groups of universal wheels for easy movement. When moved to a suitable position, a lock is provided on the universal wheel to lock the rotation of the universal wheel and fix the entire limb lifter.

[0038] In one specific embodiment, see Figure 8 In order to adjust the height of the column 12, the column 12 includes an upper column 121 and a lower column 122.

The height adjustment mechanism includes an adjustment rack 1221 arranged on the lower column 122, and the adjustment rack 1221 extends into the upper column 121. The adjustment rack 1221 and the adjustment gear 1211 are concentrically arranged with the adjustment gear 1211 and the adjustment worm wheel 1212, and the adjustment worm wheel 1212 cooperates with the adjustment worm 1213. The adjustment worm 1213 is rotatably arranged on the upper column 121 and has a crank 1214 at one end.

[0039] In one embodiment, see Figure 8 By turning the crank 1214, the adjusting worm 1213 is rotated, thereby driving the adjusting worm wheel 1212 to rotate, so as to implement the rotation of the adjusting gear 1211, and then the adjusting rack 1221 can be driven to move up and down, so as to implement the adjustment of the height of the upper column 121 extending out of the lower column 122.
