Embodiment 1

[0021] Such as figure 1 As shown, a multifunctional dermatome for burn plastic surgery includes a handle 1 and a cutting knife 2, and is characterized in that a mounting groove 3 is provided through the handle 1, and a temperature difference sheet 4 is installed in the installation groove 3, and a temperature difference sheet 4 The two sides of the handle are the high-temperature surface and the low-temperature surface respectively, and the high-temperature surface and the low-temperature surface of the temperature difference sheet 4 are attached with a temperature-conducting plate 5, and the handle 1 is installed with an electric storage sheet 6, and the electric storage sheet 6 is electrically connected with the temperature difference sheet 4, LED lamp beads 7 are installed on the sidewalls on both sides of the cutter 2, and the LED lamp beads 7 are electrically connected to the storage sheet 6, and a transparent waterproof cover is installed on the surface of the LED lamp be...

Embodiment 2

[0026] Such as figure 2 As shown, the difference between the present embodiment and the first embodiment is that: the side wall of the handle 1 is provided with a flow blocking block 11 , which is arranged in the shape of a hemispherical protrusion and is located directly below the through hole 10 .

[0027] In this embodiment, when the disinfectant flows out from the through hole 10, the disinfectant flows downwards along the surface of the handle 1 under the action of gravity and contacts the choke block 11. According to the Karman vortex effect, the sterilant bypasses the choke block 11, and periodically shed dicolumn vortices with opposite rotation directions and regular arrangement on both sides of the choke block 11, which prolongs the time for the disinfectant to stay on the surface of the handle 1, and the disinfection is more thorough and the disinfection area is larger.

Abstract

The invention belongs to the field of orthopaedic surgical instruments, and particularly relates to a multifunctional dermatome for burn and orthopaedic surgery, which comprises a handle and a cutter, a mounting groove is formed in the handle in a penetrating manner, a temperature difference piece is mounted in the mounting groove, and two surfaces of the temperature difference piece are respectively a high-temperature surface and a low-temperature surface; temperature guide plates are attached to the high-temperature face and the low-temperature face of the temperature difference piece, an electric power storage piece is installed in the handle and electrically connected with the temperature difference piece, LED lamp beads are installed on the side walls of the two sides of the cutter and electrically connected with the electric power storage piece, and a disinfection cavity is formed in the handle. A plurality of protruding air bags are arranged on the side wall of the disinfection cavity at equal intervals, and the protruding air bags are filled with heat expansion and cold contraction media. The temperature difference piece supplies power to the LED lamp beads, the working area is illuminated, the influence of the hand on light shielding is reduced, it is guaranteed that an operation is conducted safely and effectively, disinfectant is sucked through the disinfection cavity and squeezed out in the using process, and the surfaces of the handle and the cutter are disinfected.

Description

technical field [0001] The invention belongs to the field of plastic surgery instruments, and in particular relates to a multifunctional dermatome for burn plastic surgery. Background technique [0002] The dermatome is a commonly used instrument in the burn plastic surgery process. It is mainly used in the cutting of blade thickness skin slices, the scab removal and debridement of deep burn wounds and granulation wounds. When the existing dermatome is in use, due to the operation process, The doctor holds a dermatome to remove the skin from the burn wound of the patient. The light is easily blocked by the hand and the blade, resulting in insufficient light in the working area. It is very troublesome to frequently adjust the irradiation angle of the surgical light, and the dermatome is exposed during work. In the air, it is easy to adhere to bacteria and dust, and it is easy to cause the problem of infection of the patient's burn wound during the skin removal process. [00...
