A glove body for wearing during an implementation of closed fracture reduction is provided, piezoelectric thin film sensors capable of detecting pressures during the implementation of closed fracture reduction are arranged on the glove body, a data collection module is configured to collect a pressure signal detected by each piezoelectric thin film sensor, and a wireless transmission module is configured to transmit the pressure signal to a processing apparatus, so that force applied points and force applied parameters when the diaplasis is performed can be accurately acquired, which is convenient for subsequent case guidance, robot-arm implementation, medical course, etc.
In the embodiments of the present disclosure, as shown in
Optionally, the glove body 10 may be made of silicone or a flexible cloth. The pressure sensor 11 may be enclosed in an interior of the glove body 10 or on an inner surface of the glove body 10, and may sense a pressure applied at a corresponding position during the implementation of closed fracture reduction and convert a pressure value into an electrical signal.
Each pressure sensor 11 on the glove body 10 corresponds to one force applied point, and the pressure sensors 11 at different positions detect pressure signals at corresponding positions respectively.
In the embodiments of the present disclosure, optionally, the pressure sensor 11 is any one of a capacitive pressure sensor, a piezoresistive pressure sensor and a piezoelectric thin film sensor, preferably the piezoelectric thin film sensor, and may accurately detect and acquire the pressure signal at each position point. The larger the number of the pressure sensors 11 arranged on the glove body 10, pressure signals at more force points may be acquired, and the more accurate an analysis of the force applied parameters in a process of closed fracture reduction.
In the embodiments of the present disclosure, in order to accurately detect the force applied parameters in the process of closed fracture reduction and avoid an over-complicated data processing, the positions, provided with the pressure sensors 11, on the glove body 10 include a position corresponding to a first position on the palm used to fix the force applied part and a position corresponding to a second position on the palm used to perform traction and diaplasis on the force applied part when the diaplasis is performed by using the glove body.

A second process is a diaplasis process. In the process, five fingers, a thenar position, a lateral position at a first joint of an index finger close to a thumb, a lateral position at a second joint of the index finger close to the thumb, a position at the first joint of the index finger on a palmar surface and a position at the second joint of the index finger on the palmar surface of each of the doctor's two hands are all required to be participated in an alignment process of two sides of fracture ends in a cooperation manner.
