Abstract

The utility model discloses a traction table. A frame body is composed of two slide rails; a movable universal traction frame, an X-ray negative frame and a forearm fixing frame are respectively arranged on the frame body in parallel through a base with through holes. Moreover, regulators for fluted discs are installed on the three frames. A shaft sleeve base is arranged on the universal traction frame. A screw rod shaft with a crank penetrates through a shaft sleeve tube in an inner hole of the shaft sleeve base to be in threaded connection with a traction shaft. The crank is rotated, so that the traction shaft and the traction frame above the traction shaft are driven by a screw rod shaft to do axial movement. The axial force which is produced by the traction shaft and the traction frame carries out traction reduction to arms which are fixed on the tray of the traction frame and the forearm fixing frame. The regulator for the fluted discs can arbitrarily change the traction direction. The utility model is suitable for traction reduction for forearm fracture under various conditions. The utility model has the advantage of simple operation. The traction table can raise the quality of traction reduction operations.

Description

A kind of traction table

This utility model relates to medical apparatus and instruments, relates to a kind of traction table specifically.

Traction table is used in bone surgery in a large number as the isolated plant of treatment fracture, and the distal forearm fracture is in treatment, no matter be manual reduction or operative reduction, usually need traction table to reset, traditional traction table is a suspension, patient's arm is bent 90 ° at elbow during use, makes upper arm become level, and finger links to each other with fixing spring according to fingerstall, pass pulley at the upper arm ancon by steel wire and suspend a weight in midair, produce a horizontal axis pulling force, horizontal pull is opposite with the spring force action direction, and combined effect is on the forearm axis that becomes horizontal positioned, fracture end is formed reverse traction, play reset response, but this suspension traction table is being deposited following shortcoming, promptly can only keep axial traction, can not change lead and angle, and because the power that suspention produces is elastic force, so its retentivity is relatively poor, influence operation technique, the spring and the structure of steel wire that have the suspension traction table to adopt again make that the traction table volume is big, are unfavorable for operation technique.
