The invention discloses a
prone position frame warm-keeping mechanism for a
spine surgery and used for long time. The
prone position frame warm-keeping mechanism comprises a supporting base, a warm keeping
assembly and a temperature adjusting
assembly; a rotary button is rotated to be started, and based on the principle that the larger the current is, the higher the
heating effect is, when the resistance
value passing through a circuit is becoming higher, the current is smaller, an inner button can be matched to rotate to drive a connecting rod to rotate, and four resistors R1, R2, R3 and R4 are distributed in sequence; when the connecting rod rotates to the connecting
resistance wire between the R1 and the R2,
electricity enters from the inlet wire, passes through one
resistor that is R1and then is output from the outlet wire; when the connecting rod rotates to the connecting
resistance wire between the R2 and the R3, the
electricity enters from the inlet wire, passes through the tworesistors that are R1 and R2 and then is output from the outlet wire, and the current becomes lower, and the rest can be done in the same manner; and when the connecting rod rotates to the resistancewire between the R4 and a second limiting plate, the current is lowest, and therefore, the temperature of the heating wire can be adjusted, the temperature of the body part and the
abdomen of the patient attached to the
lying plate is mainly protected, and the body temperature of the patient is prevented from decreasing too much due to long-time operation.
