intraoperative limb traction device

Abstract

The invention discloses an intranperative limb traction device which comprises a support plate I and a spool, wherein the spool comprises a cylindrical tube and protecting plates which are fixed on two sides of the cylindrical tube; an inflation sleeve is arranged on a side part of the support plate I; a connector is fixed at the end part of the inflation sleeve; a pull rope is arranged at a side part of the connector; a pulley for guiding the pull rope is mounted on the support plate I; a tightening mechanism is arranged at the side part of the pulley. The intranperative limb traction device is smart in structural design and worthy of popularization and application as the tightening mechanism can be adopted to tighten or release the pull rope fixed on the inflation sleeve.

Description

technical field [0001] The invention relates to a medical device, in particular to an intraoperative limb traction device used for traction of limbs during operation. Background technique [0002] Traction technique uses the principle of action force and reaction force to resist the tension or retraction of soft tissue and restore the dislocated area to its original position. [0003] The current way to reset the pelvic dislocation area is that the doctor opens the human pelvis during the operation to expose the pelvis, and then the doctor manually pulls the limbs to drive the hip bone in the pelvis to move down, and manually presses the hip bone into the sacrum where it is reset to the sacrum. Joints, but the tension of the artificial traction limbs is uneven. Either the tension is too large and the hip bone moves down too much, or the tension is too small and the hip bone does not move down enough. It is difficult to ensure that the hip bone moves down just right. At the ...

[0003] The current way to reset the pelvic dislocation area is that the doctor opens the human pelvis during the operation to expose the pelvis, and then the doctor manually pulls the limbs to drive the hip bone in the pelvis to move down, and manually presses the hip bone into the sacrum where it is reset to the sacrum. Joints, but the tension of the artificial traction limbs is uneven. Either the tension is too large and the hip bone moves down too much, or the tension is too small and the hip bone does not move down enough. It is difficult to ensure that the hip bone moves down just right. At the quasi-sacral joint, it takes a long time to adjust, which increases the operation time and increases the pain of the patient
