Manual eschar grinding device

Abstract

The invention discloses a manual scab remover, which comprises a glove body, a plurality of grinding sheets are detachably arranged on the glove body, at least one grinding sheet is arranged on the thumb side of the glove body, and the outer surface of the grinding sheet is concave-convex Uneven grinding surface; through the setting of gloves, medical workers can feel the contact force with the patient's skin in real time, and flexibly adjust the force according to the wound surface, avoiding the contact of the knife or handle-shaped scab device in the prior art If the area is too large, the grinding force is difficult to control, and it is easy to cause excessive excision, sacrificing the local function of the patient's wound after healing, or it cannot be completely removed, and it is easy to sacrifice the interstitial ecological tissue due to secondary infection of the wound.

Description

technical field [0001] The invention relates to a manual scab remover. Background technique [0002] The treatment of burn wounds has always been the focus and difficulty of research and treatment in the field of burn surgery. The tissue after burn is divided into necrotic tissue, interecological tissue and normal tissue from superficial to deep. The necrotic tissue has lost its blood supply and begins to be invaded by bacteria within a few minutes. The bacterial content is as high as 10 within 6 hours after injury. 6 / cm 3 . Interstitial tissue refers to the tissue layer with damaged cells, strong inflammatory response, and obvious edema. It can have two outcomes: if it is invaded by bacteria from necrotic tissue, wound sepsis and secondary tissue necrosis will occur; If the wound is properly treated and deep tissue infection does not occur, the blood supply and cell repair will be gradually restored. Therefore, early and accurate removal of necrotic tissue in burn wou...

Problems solved by technology

[0004] The Chinese patent with the application number 201410567776.1 provides an adjustable electric negative pressure grinding scab machine, which has a displacement adjustment mechanism and a tool box. The movement and work of the tool can be realized through the control of the stepping motor of the displacement adjustment mechanism. It is convenient and quick to remove the necrotic scabs on the wound surface of burn patients, realize cooling and instant flushing of scabs and residual blood on the wound, and at the same time absorb the washed scabs and residual blood to ensure the cleanliness of the skin surface. However, in practice Clinically, there are many inconveniences: (1) High-speed rotating grinding can cause the temperature of the tissue surface to rise significantly, and capillary blood coagulation on the wound surface, aggravated blood flow disorders, resulting in secondary heat damage and deepening of the wound surface; (2) Tool contact If the area is too large and the grinding force is too large, it is easy to cause excessive excision on the sides of the nose, ears, and around the eyes, etc. Sacrifice the interstitial ecological tissue due to secondary infection of the wound surface; (3) Unable to sense the magnitude of the grinding force, which is easy to cause secondary damage to the wound
