Title: Cast removing tool

Description:
BACKGROUND OF THE INVENTION 
     1. Fields of the Invention 
     The present invention relates to a cast removing tool, and more particularly, to a cast removing tool with a cutting member to remove cast from patient&#39;s limb while protecting the patient from being hurt by the cutting member. 
     2. Descriptions of Related Art 
     When a bone injury happens such as a bone fracture, a cast is applied to the injury area to hold the bone once the bone is set so that the bone does not move. The cast has to be removed when the bone fracture problem is fixed. The conventional way to remove the cast is to carefully use a saw to cut the cast and then remove the cast from the patient&#39;s limb. The cutting process should be taken carefully to avoid hurting the patient. 
     The present invention is intended to provide a cast removing tool including a protection member to eliminate the drawbacks mentioned above. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a cast removing tool and comprises a handle having a battery received therein. A switch is connected to the outside of the handle and electrically connected to the battery. A link is connected to the front end of the handle and a motor is connected to the link. The motor has an output shaft which protrudes beyond the link. A cable is electrically connected between the motor and the battery. A cutting tool is connected to the output shaft of the motor so as to be driven by the motor. A protection member is connected to the handle and is a curved member. The protection member extends to be located beneath the cutting tool. 
     The advantage of the present invention is that the protection member is located between the cutting tool and the patient limb so that the cutting tool cannot touch the patient&#39;s limb. 
     The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIGS. 1 and 2 , the cast removing tool of the present invention comprises a handle  1 , a cutting tool  4  and a protection member  5 . The handle  1  has a battery  10  received therein. A switch  11  is connected to the outside of the handle  1  and electrically connected to the battery  10 . A link  2  is connected to the front end of the handle  1  and a motor  3  is connected to a bent portion of the link  2 . The motor  3  has an output shaft  30  which protrudes beyond the bent portion of the link  2 . A cable  31  is electrically connected between the motor  3  and the battery  10 . The cutting tool  4  is connected to the output shaft  30  of the motor  3 . In this embodiment, the cutting tool  4  is a disk saw. The protection member  5  is connected to the bottom of the handle  1  and is a curved member. The protection member  5  extends to be located beneath the cutting tool  4 . 
     As shown in  FIGS. 3 and 4 , when in use, the protection member  5  is inserted between the patient&#39;s limn “A” and the cast “B”, and the cutting tool  4  is activated by operating the switch  11  on the handle  1 . The handle  1  is pushed downward and the cutting tool  4  starts to cut the cast “B”. Because the protection member  5  is located between the patient&#39;s limn “A” and the cast “B”, so that the cutting tool  4  does not hurt the patient. The present invention has a simple structure and is easily to use. The patient is well protected by the protection member  5 . 
     While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
