Description

Technical Field

[0001] This utility model specifically relates to an auxiliary device for burn plastic surgery skin grafting. Background Technology

[0002] When the skin suffers extensive full-thickness skin loss, skin grafting is a feasible and effective surgical treatment method, and its application is extremely important in burn patients.

[0003] During burn reconstructive surgery and skin grafting, the limb requiring skin grafting needs to be lifted by additional medical staff to facilitate the procedure. Manually lifting the patient's limb for extended periods can be labor-intensive for medical personnel. Therefore, specialized auxiliary equipment is now used to suspend the patient's limb.

[0004] For example, Chinese utility model patent with publication number CN220158676U provides an auxiliary device for skin grafting in burn and plastic surgery. When using the device, it is fixed to the edge of the operating table. The patient's limb is passed through the cavity between the second fixation plate and the first fixation plate and placed on the second fixation plate. The patient's limb is then slightly lifted, and the first knob is turned. The first knob drives the first threaded rod to rotate. The rotation of the first threaded rod drives the second fixation plate to move closer to the first fixation plate, so that the first fixation plate and the second fixation plate close together to fix the patient's limb. The patient's limb is then lifted again.

[0005] However, existing auxiliary devices have been found to have certain shortcomings in use. The traditional limb slings used in burn plastic surgery and skin grafting are cumbersome to fix the limb, which leads to a decrease in fixation efficiency and is prone to causing secondary damage to the burn site during the fixation process. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model proposes an auxiliary device for burn plastic surgery skin grafting, which solves the technical problems mentioned in the background art, such as the cumbersome fixation of limbs by traditional limb slings used in burn plastic surgery skin grafting, resulting in reduced fixation efficiency and the risk of secondary damage to the burn site during fixation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for burn plastic surgery skin grafting, comprising:

[0008] A base, on which a housing is horizontally slidably mounted;

[0009] There are two sets of clamping plates arranged opposite each other, and both sets of clamping plates are hinged to the housing. Each end of the two sets of clamping plates is provided with a support rod. When the two sets of clamping plates are closed, multiple sets of support rods are arranged in an alternating manner.

[0010] A mounting rod, which can be raised and lowered, is inserted through the bottom of the housing, and a pressure plate is provided at the bottom of the mounting rod; and

[0011] An opening and closing mechanism is provided on the mounting rod and connected to the two sets of clamps to convert the sliding of the mounting rod into driving the clamps to rotate and open, and to selectively lock or unlock the position of the clamps.

[0012] Furthermore, a support rod is provided on the base, and an installation ring is provided on the housing. The installation ring is slidably sleeved on the support rod, and a set screw is screwed onto the installation ring. The end of the set screw abuts against the support rod.

[0013] Furthermore, a winding device is provided at the bottom of the mounting ring, and a retractable pull rope is provided inside the winding device, which is fixedly connected to the housing.

[0014] Furthermore, the opening and closing mechanism includes:

[0015] A connecting bracket is mounted on the mounting rod and located within the housing;

[0016] A drive assembly, disposed on the connecting frame and connected to the two sets of clamping plates, converts the sliding of the mounting rod into driving the two sets of clamping plates to rotate and open / close; and

[0017] A locking component, disposed on the connecting frame and connected to the housing, is provided to selectively lock or unlock the position of the connecting frame.

[0018] Furthermore, the driving component includes:

[0019] Two sets of straight racks are provided, arranged opposite to each other at both ends of the connecting frame; and

[0020] A gear is disposed at the hinge between the clamping plate and the housing and meshes with one of the sets of the spur racks.

[0021] Furthermore, the locking component includes:

[0022] Wedge-shaped blocks are disposed on the connecting frame;

[0023] A ratchet rack is slidably disposed within the housing and engages with the wedge block;

[0024] A first elastic element is disposed between the ratchet rack and the housing; and

[0025] A control lever is mounted on the ratchet rack and slides through the housing and extends outward. A button is provided at one end of the control lever located outside the housing.

[0026] Furthermore, a second elastic element is provided between the connecting frame and the top of the housing.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] This device suspends the limb awaiting skin grafting. Initially, both sets of splints are open, with the pressure plate at its lowest point furthest from the housing. During use, the device or the patient's limb can be moved to bring the pressure plate closer to the limb. Pressing down on the housing causes the mounting rod to slide upwards within it. As the mounting rod slides, the opening and closing mechanism drives the two sets of splints to rotate and close, locking their positions. This allows the splints to quickly clamp the patient's limb until the multiple support rods at the bottom of the two sets of splints are staggered, thus quickly suspending the limb for subsequent skin grafting surgery. The entire limb fixation process is convenient and quick, and avoids direct contact with the burn area, effectively preventing secondary damage to the patient's wound. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0040] Example:

[0041] like Figure 1 As shown, this utility model provides an auxiliary device for burn plastic surgery skin grafting, including a base 101, a housing 201 horizontally slidably mounted on the base 101, a support rod 102 mounted on the base 101, and a mounting ring 103 mounted on the housing 201. The mounting ring 103 is slidably sleeved on the support rod 102, and a set screw 104 is screwed onto the mounting ring 103, with the end of the set screw 104 abutting against the support rod 102. A winding device 105 is provided at the bottom of the mounting ring 103, and a retractable pull rope 106 is provided inside the winding device 105, which is fixedly connected to the housing 201.

[0042] In use, the base 101 can be fixed to the surgical area, and the position of the mounting ring 103 on the support rod 102 can be adjusted according to the location of the burn. After adjustment, the position of the mounting ring 103 is fixed by the set screw 104. Alternatively, the pull rope 106 can be loosened by the take-up device 105, and the housing 201 can be moved closer to the patient's limb to facilitate limb lifting. Furthermore, in some preferred embodiments, two or more sets of housings 201 can be used for more stable limb fixation.

[0043] like Figure 2 As shown, in this embodiment, two sets of oppositely arranged clamping plates 202 are hinged on the housing 201. Each end of the two sets of clamping plates 202 is provided with a support rod 203. When the two sets of clamping plates 202 are closed, multiple sets of support rods 203 are arranged in an alternating manner. An installation rod 301 is provided through the bottom of the housing 201 in a height-adjustable manner. A pressure plate 302 is provided at the bottom of the installation rod 301.

[0044] After the housing 201 is moved onto the patient's limb, the pressure plate 302 comes into contact with the patient's limb, and the two sets of clamps 202 are controlled to close so that the two sets of clamps 202 and the pressure plate 302 form a cavity to accommodate the patient's limb. The arrangement of multiple sets of support rods 203 can stably support the patient's limb. The staggered arrangement of multiple sets of support rods 203 can effectively prevent the patient's limb from falling off the two sets of clamps 202.

[0045] like Figures 2 to 4 As shown, in this embodiment, the mounting rod 301 is provided with an opening and closing mechanism connected to two sets of clamping plates 202. This mechanism converts the sliding of the mounting rod 301 into driving the clamping plates 202 to rotate and open, and can selectively lock or unlock the position of the clamping plates 202. The opening and closing mechanism includes a connecting frame 303 mounted on the mounting rod 301 and located within the housing 201. The connecting frame 303 is provided with a drive assembly connected to the two sets of clamping plates 202. This drive assembly converts the sliding of the mounting rod 301 into driving the two sets of clamping plates 202 to rotate and open. The drive assembly includes two sets of spur racks 305 arranged opposite to each other at both ends of the connecting frame 303. A gear 204 is provided at the hinge point between the clamping plate 202 and the housing 201, and the gear 204 meshes with one set of spur racks 305.

[0046] After the pressure plate 302 comes into contact with the patient's limb, the housing 201 is pressed down to push the mounting rod 301 upward within the housing 201, thereby causing the two sets of racks 305 to move upward. During the movement, the two sets of racks 305 can drive the two sets of clamping plates 202 to rotate and close by meshing with the gear 204 until the two sets of clamping plates 202 clamp the patient's limb. The pressure plate 302 is used to fix the patient's limb. Then, the pull rope 106 is retracted by the reeling device 105 to lift the patient's limb to a suitable position.

[0047] like Figures 2 to 4 As shown, in this embodiment, the opening and closing mechanism further includes a locking component. The locking component is disposed on the connecting frame 303 and connected to the housing 201, so as to selectively lock or unlock the position of the connecting frame 303. The locking component includes a wedge block 304 disposed on the connecting frame 303, a ratchet rack 401 slidably disposed inside the housing 201, the ratchet rack 401 engaging with the wedge block 304, a first elastic element 402 disposed between the ratchet rack 401 and the housing 201, a control rod 403 disposed on the ratchet rack 401, the control rod 403 slidably passing through the housing 201 and extending outward, and a button plate 404 disposed at the end of the control rod 403 located outside the housing 201.

[0048] During the process of rotating and closing the two sets of clamps 202 controlled by the movement of the pressure plate 302, the wedge block 304 moves on the ratchet rack 401. The first elastic element 402 locks the position of the wedge block 304 and the connecting frame 303 in place by the ratchet rack 401, effectively preventing the two sets of clamps 202 from opening and thus effectively fixing the patient's limb. After the surgery, pressing the pressure plate 404 causes the ratchet rack 401 to slide away from the wedge block 304, releasing the fixing of the connecting frame 303, allowing the device to be quickly removed. Furthermore, a second elastic element 205 is provided between the connecting frame 303 and the top of the housing 201. The arrangement of the second elastic element 205 allows the two sets of clamps 202 to open automatically, eliminating the need for staff to open the clamps 202 and further improving the convenience of using the device.

[0049] The specific usage and beneficial effects of this utility model are as follows:

[0050] This device suspends the limb to be grafted for plastic surgery. Initially, both sets of splints 202 are open, with the pressure plate 302 located at its lowest point away from the housing 201. During use, the device or the patient's limb can be moved to bring the pressure plate 302 closer to the limb and into contact. Then, the housing 201 is pressed down, causing the mounting rod 301 to slide upwards within it. During this sliding motion, the mounting rod 301 drives the two sets of splints 202 to rotate and close via an opening and closing mechanism, locking their positions. This allows the splints 202 to quickly clamp the patient's limb until the multiple support rods 203 at the bottom of the splints 202 are staggered, quickly suspending the limb for subsequent skin grafting surgery. The entire limb fixation process is convenient and quick, and avoids direct contact with the burn area, effectively preventing secondary damage to the patient's wound.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
