Auxiliary Positioning Device For Ultrasonic Apparatus

Abstract

An auxiliary positioning device for an ultrasonic apparatus is disclosed herein, which is installed on an ultrasonic probe. The auxiliary positioning device includes a fixing member, an adjusting member being flexible and coupled with the fixing member at one end thereof, a parallel light source coupled with the other end of the adjusting member and having a projection hole for passing a parallel light beam emitted from the parallel light source, and a cylindrical lens mounted on one end of the parallel light source in front of the projection hole, whereby the parallel light beam becomes a fanned light beam after it passes through the cylindrical lens. The auxiliary positioning device of the present invention can provide a high precise positioning for diagnosis and treatment.

1 . An auxiliary positioning device for an ultrasonic apparatus, which is installed on an ultrasonic probe, comprising:
 a fixing member;   an adjusting member coupled with the fixing member at one end thereof, in which the adjusting member is flexible;   a parallel light source coupled with the other end of the adjusting member and having a projection hole for passing a parallel light beam emitted from the parallel light source; and   a cylindrical lens mounted on one end of the parallel light source in front of the projection hole, whereby the parallel light beam becomes a fanned light beam after it passes through the cylindrical lens.   
   
   
       2 . The auxiliary positioning device as claimed in  claim 1 , wherein the parallel light source is a laser light source. 
   
   
       3 . The auxiliary positioning device as claimed in  claim 1 , wherein the fixing member is a fixing clamp. 
   
   
       4 . The auxiliary positioning device as claimed in  claim 1 , wherein the cylindrical lens is a circular cylindrical lens. 
   
   
       5 . The auxiliary positioning device as claimed in  claim 1 , wherein the cylindrical lens is a biconvex cylindrical lens. 
   
   
       6 . The auxiliary positioning device as claimed in  claim 1 , wherein the cylindrical lens is a convex-concave cylindrical lens. 
   
   
       7 . The auxiliary positioning device as claimed in  claim 1 , wherein the cylindrical lens is a plano-convex cylindrical lens. 
   
   
       8 . The auxiliary positioning device as claimed in  claim 1 , wherein the cylindrical lens is a plano-concave cylindrical lens. 
   
   
       9 . The auxiliary positioning device as claimed in  claim 1 , wherein the cylindrical lens is a biconcave cylindrical lens. 
   
   
       10 . The auxiliary positioning device as claimed in  claim 1 , wherein a battery pack is mounted between the fixing member and the adjusting member.
