Abstract:
Objective To develop a laser positioning device for GE OEC850 and Wandong HMC-36 C-arm.Methods The device was composed of two cross-type laser tubes,timing circuit and power source.The optimal 30 cm projection point was determined with laser dual-crossed-line positioning method and considerations on the distance between the tube of GE OEC850 or Wandong HMC-36 C-arm and the image intensifier.Then the projection range was found around 30 cm to define the targeted area.Results The device eliminated the needs of multi times of projection due to improper positioning,decreased the exposure to medical personnel and patient during the operation,prolonged the service life of the tube and reduced the cost for hospital equipment.Conclusion The device behaves well in positioning and easy operation,and thus is worthy promoting clinically.
