A high-speed rotary escharectomy device for deep second-degree burns

Abstract

The invention discloses a deep-second-degree burn wound high-speed rotating eschar excision device, which comprises a cutter head, wherein the cutter head is connected with a rotating power source through a transmission mechanism; a vibration mechanism is arranged in the middle of the transmission mechanism; the cutter head comprises a cutter frame; and a plurality of cutters used for eschar excision are arranged on the cutter frame. The deep-second-degree burn wound high-speed rotating eschar excision device has the beneficial effects that a cutter adopts a bent wedge-shaped structure and is provided with an elastic element, so that the telescopic flexibility of the cutting is realized; the change of an eschar excision load in a certain range can be borne; the stress condition is improved; when the preset load upper limit is exceeded, the automatic retraction is realized; the occurrence of medical accidents due to excessive excision on the burn wound part is avoided; by arranging a negative pressure adsorption tube, the collection of cut eschar fragments is realized; cut eschar fragments are prevented from falling into the device or other space positions; and the use neatness of the device is ensured. The whole device has the advantages that the structure is compact; the medical effect is good; the anti-contamination capability is high; and the portability is realized.

Description

technical field [0001] The invention relates to a high-speed rotary escharectomy device for deep second-degree burns, belonging to the field of precision medical instruments. Background technique [0002] A deep second-degree burn develops a scab over the surface of the skin over time. For the treatment of deep second-degree burns after scabs, medical instruments are generally used to remove the scabs, improve the skin surface, and then perform skin grafting, so that the burns can be effectively treated. [0003] At present, among the medical devices for treating deep second-degree burns and scab removal at home and abroad, scrubbing devices and medical technology are widely used, but the temperature generated during the scrubbing process is relatively high, and the debris formed is difficult to handle, which increases the difficulty of the operation. And seriously restricted the recovery of burn patients. At the same time, the escharectomy device and its application techno...

Problems solved by technology

[0003] At present, among the medical devices for treating deep second-degree burns and scab removal at home and abroad, scrubbing devices and medical technology are widely used, but the temperature generated during the scrubbing process is relatively high, and the debris formed is difficult to handle, which increases the difficulty of the operation. And seriously restricted the recovery of burn patients. At the same time, the escharectomy device and its application technology are relatively less developed, and the escharectomy does not have the eschar-dissolving process of deep second-degree burn wounds, which can reduce the pain of patients and significantly reduce the impact on patients. Possibility of wound infection and systemic infection in deep second degree burns necessitates research on rotary escharectomy devices for deep second degree burns
