A eschar scraping structure is mounted in the device shell; the utility model relates to the technical field of metal smelting auxiliary equipment, the device ingeniously integrates a eschar loosening treatment structure and a eschar scraping structure, firstly, the eschar loosening treatment structure accurately acts on the surface of an anode carbon block main body, and stubborn attached eschar and dirt are carefully released and separated in a mild and efficient mode; the process enables the attached eschar structure to become fragile, the eschar structure can be conveniently removed from the anode carbon block main body subsequently, and then through intervention of the well-designed eschar scraping structure, the released eschar is thoroughly scraped with the minimum invasiveness and the maximum removing efficiency.

The application discloses a burn wound eschar grinder, which comprises an eschar grinder body, an eschar grinder head arranged in the eschar grinder body, an outer tube arranged on the eschar grinder body, a pus removing assembly arranged on the eschar grinder body, an eschar grinding mechanism arranged in the eschar grinder body and a sundry collecting assembly arranged on the outer tube. The eschar grinder can collect the eschar generated during the pus removing and eschar grinding. The eschar grinder is different from the prior art, and the pus under the eschar can be removed by the pus removing assembly and the eschar grinder head when a medical staff grinds the eschar of a patient. The eschar grinder head is connected with the eschar grinding mechanism by pulling the eschar grinding mechanism upward, and then the eschar grinder head is driven to rotate, so that the ground eschar is prevented from scattering around and further infecting the wound position.

The invention discloses a bipolar cutting blood coagulation surgical instrument and belongs to the field of medical instruments. The instrument comprises an upper shear blade, an upper electrocoagulation forceps piece, a lower shear blade, a lower electrocoagulation forceps piece and a fixing clamping piece which are integrally formed, only a cutting edge and a blood coagulation occlusal surface are conductive through an insulation structure design, and the rest parts are covered with an insulation coating. When in use, the bipolar loop reduces tissue damage, the operation time is shortened by synchronously cutting blood coagulation, and the risks of blood vessel electric damage, eschar and thrombus formation are avoided. The instrument can be sterilized at high temperature and high pressure, can be reused, and is economical and environment-friendly.

A non-enzymatic debridement agent that is less expensive, less cytotoxic, and more effective than enzymatic and sharp surgical debridement of eschar material. The non-enzymatic debridement agent is based on a formulation of detergent with a high critical micelle concentration and a denaturing agent along with an optional optimized buffer. The non-enzymatic wound debriding agent is able to dissolve eschar material in under one week. The buffer or ointment may contain an optimized pH, salt concentration, reducing agent, and other components that aid in the debridement of eschar material from chronic wounds and burn wounds. The non-enzymatic debridement agent can be formulated as an ointment, liquid rinse under pressure, and / or as a combination product with an advanced wound dressing that can act as a sink to remove the solubilized eschar material from the surface of the wound to assist in the debridment and proper healing of wounds.

The utility model discloses a special scab removal movable frame for burn nursing, and relates to the technical field of burn nursing scab removal, the special scab removal movable frame comprises a bottom plate, the upper surface of the bottom plate is rotatably provided with a rotating shaft, the outer wall of the top end of the rotating shaft is fixedly provided with a bearing assembly, and the bearing assembly comprises a bottom frame fixedly connected to the upper surface of a worm wheel. Firstly, a new sanitary pad film is flatly laid on the supporting plate and pressed downwards, when the supporting plate moves downwards, the rolling wheel is pressed, the pressing rod and the mounting plate are driven to rotate till the sanitary pad film is clamped by the buffering pad to complete fixing and limiting, and the supporting plate moves downwards to extrude the two sets of clamping rods to extend outwards and stretch the first spring; when the lower surface of the supporting plate makes contact with the bottom end of the inner wall of the bottom frame, the first spring rebounds and drives the clamping rod to be inserted into the rectangular clamping hole to fix the supporting plate, the clamping rod is pulled outwards to be separated from the rectangular clamping hole to relieve limiting of the supporting plate during dismantling, the supporting plate moves upwards and does not extrude the pressing rod any more, and the pressing rod rotates to reset through the torsional spring to relieve fixing of the corners of the sanitary pad film. Disassembly and assembly operation is convenient, consumed time is short, and operation difficulty is low.

The utility model relates to medical instrument technical field especially relates to a kind of multifunctional surgical electric knife, it includes processor, shell, electric knife blade, suction assembly and scab-removing component, the scab-removing component includes being set in shell and the scab-removing head with the opening for the electric knife blade to protrude one end, the scab-removing blade for scraping off eschar on electric knife blade is set in opening place, and the sliding mechanism for driving electric knife blade to slide in scab-removing head and then make the eschar on electric knife blade be scraped off by scab-removing blade is connected on electric knife blade, the suction port is arranged between the scab-removing head and shell, the suction assembly includes the suction pipe being set in shell and one end with suction port intercommunication and the suction tube other end intercommunication and for producing suction force suction device, the electric knife blade and suction device are electrically connected with processor.This surgical electric knife is various in function, overall volume is smaller and user operation is more convenient.

The application discloses application of L- kynurenine in preparation of a medicine for preventing and / or treating ultraviolet light induced skin photo-damage. The application proves that L- kynurenine has a significant anti-photo-damage effect by a UVA irradiation HaCaT cell model, can enhance mitochondrial function and promote mitochondrial biogenesis, thereby improving the antioxidant capacity of cells and reducing inflammatory reactions. The application also verifies that a hydrogel containing L- kynurenine can effectively repair mouse back skin damage caused by ultraviolet light through a UVA combined with UVB irradiation back depilation mouse model, improve the water content and antioxidant capacity of the skin, and reduce inflammatory reactions, edema, roughness, erythema or eschar and other phenomena. Therefore, the application provides a reference direction for development, utilization and popularization of L- kynurenine for preparing a medicine or a medical cosmetic product for repairing skin photo-damage.
