Eschar grinding surgical instrument capable of sensing and displaying application force in real time

Abstract

The invention discloses an eschar grinding surgical instrument capable of sensing and displaying application force in real time. The eschar grinding surgical instrument comprises a glove body detachably provided with a plurality of grinding patches. At least one grinding patch is arranged on the thumb side of the glove body, the outer surfaces of the grinding patches are rugged grinding surfaces, an interlayer is arranged on the palm side of the glove body, a pressure sensor used for sensing the application force of a hand is arranged in the interlayer, and data collected by the pressure sensor is transmitted to a signal receiver to be displayed. By arranging the glove body, medical staff can sense the contact force with the skin of a patient in real time and adjust the strength flexibly according to the condition of a wound, and thus the situations that in the prior art, the contact area of a cutter or an eschar grinding instrument in a handle shape is too large, the grinding force is not easy to master, excessive removing is likely to occur, the local function achieved after healing of the wound of the patient is sacrificed, or thorough removing cannot be achieved, and anabiotic tissue is likely to be sacrificed due to secondary infection of the wound are avoided.

Description

technical field [0001] The invention relates to an eschar surgical device which senses applied force and displays it in real time. 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. Therefor...

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; (3) Cannot perceive and display the grinding force, which is easy to cause secondary damage to the wound
