In vitro intelligent positioning device for long bone fractures and using method

Abstract

The invention relates to an in vitro intelligent positioning device for long bone fractures, comprising a positioning block, a guide column, a positioning column, a bone needle, a laser light, a photosensitive sensor, a positioning pin, a pressure sensor and a control circuit. At least two guide holes, at least one bone needle positioning hole and at least two limit holes, the positioning block is slidably connected with the guide column through the guide hole, the positioning block is connected to the bone needle through the bone needle positioning hole, and the positioning block passes through the limit The hole and the positioning column are connected to each other; the method of use includes four steps of initial positioning of the wound, strengthening the connection, inspection and care, and equipment removal. The present invention can effectively realize the effective strengthened positioning of the fractured part of the long bone, and at the same time, it can also greatly facilitate the continuous detection of the stress state and displacement state of the fractured part during the healing process, and the detection operation has high precision, and the detection result is readable. Easy to take.

Description

technical field [0001] The invention relates to an in vitro intelligent positioning device for long bone fractures and a use method thereof, belonging to the field of medical technology. Background technique [0002] At present, when positioning long bone spicules, it is often to use traditional internal or external splints and other equipment or tools to position and strengthen the fractured long bones, so as to facilitate fracture wound healing. For example, the patent document with application number 201110358415. A device for locating long bone fractures located outside the body was recorded, but in actual diagnosis and treatment activities, it was found that due to factors such as external force impact and human muscle tissue movement, it is very easy to cause the fracture wound to shift and dislocate during the healing of long bone fractures. In severe cases, it is even necessary to use the surgical light for treatment again, and it is easy to cause deformities in the ...

[0002] At present, when positioning long bone spicules, it is often to use traditional internal or external splints and other equipment or tools to position and strengthen the fractured long bones, so as to facilitate fracture wound healing. For example, the patent document with application number 201110358415.2 is A device for locating long bone fractures located outside the body was recorded, but in actual diagnosis and treatment activities, it was found that due to factors such as external force impact and movement of human muscle tissue, it is very easy to cause the fracture wound to shift and dislocate during the healing of long bone fractures. In severe cases, it is even necessary to use the surgical light for treatment again, and it is easy to cause deformities in the wound site after the long bone heals, which seriously affects the treatment effect of the long bone fracture and causes greater pain to the patient. However, these treatments currently used Neither the equipment nor the corresponding operation method can effectively detect the force and deviation of the long bone during the healing process, and at the same time, it is impossible to directly obtain accurate detection results, often requiring the use of X-ray machines and other equipment It can only be realized, the detection operation is difficult, the flexibility is poor, and there are also defects of poor precision, so that it cannot effectively meet the needs of actual use. Meet the needs of actual use
