Distal radius fracture reduction and force measurement device

Abstract

The invention discloses a distal radius fracture reduction and force measurement device. The device comprises a forearm and elbow joint supporting system, a biplanar arc-shaped guide rail system, an upper arm fixing system, a thumb traction system and a palm traction system, wherein the biplanar arc-shaped guide rail system and the upper arm fixing system are arranged on the forearm and elbow joint supporting system, and the thumb traction system and the palm traction system are arranged on the biplanar arc-shaped guide rail system. According to the device, all key assemblies can allow X rays to transmit, and therefore a doctor can conveniently monitor and judge the reduction effect during an operation; after a satisfactory fracture reduction effect is achieved, the device can be locked to keep the reduction state, and reduction losing possibly occurring in the plaster immobilization process is avoided; most importantly, the device can measure some biomechanical key parameters in the reduction process in real time, and a theoretical basis and a possible way are provided for normalized, quantified and precise operation of fracture reduction.

Description

technical field [0001] The invention belongs to the fields of surgical non-invasive medical engineering technology, medical robots and new scientific instruments for medical research, and relates to a force measuring device for the reduction of distal radius fractures. Background technique [0002] Distal radius fractures are very common clinically. At present, the phenomenon of excessive medical treatment for distal radius fractures is becoming more and more serious clinically. The traditional manipulative reduction technique has a definite curative effect, and its cost-effectiveness ratio is extremely high compared with surgical treatment. However, there is a lack of clinical basic research on the biomechanical measurement and analysis of manipulative reduction at home and abroad, which has led to the long-term stagnation of this technique in the empirical operation stage and cannot be achieved. The formation of standardized operating specifications has resulted in uneven ...
