Periosteal elevator with a tissue combing and pulling structure

Abstract

A periosteal elevator with a tissue combing and pulling structure comprising a bar, a combing and pulling base, and a plurality of combing and pulling structures is provided. The bar has a holder and a connection part, wherein the holder is utilized for being held by an operation executer, and the connection part is connected to the holder. The combing and pulling base is fixed to the connection part and has a base outer edge part. The combing and pulling structures are protruded opposite to the bar from the base outer edge part, for combing and pulling a subcutaneous fibrous tissue when the subcutaneous fibrous tissue is cut and elevated from an alveolar bone.

What is claimed is:

 a bar, having a holder and a connection part, wherein the holder is utilized for being held by an operation executer, and the connection part is connected to the holder;   a combing and pulling base, fixed to the connection part, and having a base outer edge part; and   a plurality of combing and pulling structures, protruded opposite to the bar from the base outer edge part, for combing and pulling a subcutaneous fibrous tissue when the subcutaneous fibrous tissue is cut and elevated from an alveolar bone.   
     
     
         2 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein the combing and pulling base is a spoon-shaped base. 
     
     
         3 . The periosteal elevator having a tissue combing and pulling structure of  claim 2 , wherein the combing and pulling base has a base trench. 
     
     
         4 . The periosteal elevator having a tissue combing and pulling structure of  claim 2 , wherein the base outer edge part is a curved outer edge part. 
     
     
         5 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein the combing and pulling base is a plate-shaped base. 
     
     
         6 . The periosteal elevator having a tissue combing and pulling structure of  claim 5 , wherein the base outer edge part comprises a straight outer edge part. 
     
     
         7 . The periosteal elevator having a tissue combing and pulling structure of  claim 5 , wherein each of the combing and pulling structures is extended along a protruding direction, the holder is extended along a first extending direction, and the protruding direction is substantially parallel to the first extending direction. 
     
     
         8 . The periosteal elevator having a tissue combing and pulling structure of  claim 5 , wherein each of the combing and pulling structures is extended along a protruding direction, the holder is extended along a first extending direction, an included angle is formed between the protruding direction and the first extending direction, and the included angle is ranged between 10 degrees to 90 degrees. 
     
     
         9 . The periosteal elevator having a tissue combing and pulling structure of  claim 6 , wherein the combing and pulling structures are linearly aligned at the base outer edge part. 
     
     
         10 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein the combing and pulling structures are equally spaced. 
     
     
         11 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein each of the combing and pulling structures is protruded from the base outer edge part by a protruding length, and the protruding length is ranged between 0.5 mm to 1.5 mm. 
     
     
         12 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein the holder is extended along a first extending direction, the connection part is extended along a second extending direction, and the first extending direction is substantially parallel to the second extending direction. 
     
     
         13 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein the holder is extended along a first extending direction, the connection part is extended along a second extending direction, and the first extending direction is substantially perpendicular to the second extending direction. 
     
     
         14 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein the connection part has an extending section and a bended section, the extending section is extended along a second extending direction, the bended section is extended along a bended direction, and the bended direction is substantially perpendicular to the second extending direction. 
     
     
         15 . The periosteal elevator having a tissue combing and pulling structure of  claim 14 , wherein the holder is extended along a first extending direction, and the first extending direction is substantially parallel to the second extending direction. 
     
     
         16 . The periosteal elevator having a tissue combing and pulling structure of  claim 1 , wherein the bar further comprises an expanded connection part, and the expanded connection part is connected to an end of the holder opposite to the connection part. 
     
     
         17 . The periosteal elevator having a tissue combing and pulling structure of  claim 16 , further comprising:
 an expanded combing and pulling base, fixed to the expanded connection part, and having an expanded base outer edge part; and   a plurality of expanded combing and pulling structures, protruded from the expanded base outer edge part, for combing and pulling the subcutaneous fibrous tissue.
