Benefits of technology

The present invention provides a periosteal elevator with a tissue combing and pulling structure that can increase the stretchable length of subcutaneous fibrous tissue without causing swelling or infection. This is helpful for doing stress relaxation suture without forming cuts. Overall, this technology helps improve the efficiency and safety of the surgical procedure.

Problems solved by technology

After completing the above mentioned operations, the dentist needs to stitch the elevated subcutaneous fibrous tissues PA22a and PA22b. However, because of the bone powder PA4 added in the alveolar bone PA21 surrounding the implant PA3, the wound would be protruded in compared with the condition before the implant placement surgery such that it would be difficult for the dentist to stitch the subcutaneous fibrous tissues PA22a and PA22b without any treatment.
However, cutting the subcutaneous fibers may cause bleeding.

first embodiment

[0060]Please refer to FIG. 6 and FIG. 6A, wherein FIG. 6 is a perspective view showing the periosteal elevator having a tissue combing and pulling structure provided in accordance with the present invention from a different viewing angle, and FIG. 6A is an enlarged view showing the region B of FIG. 6.

[0061]As shown, the holder 111 is extended along a first extending direction D1, the connection part 112 is extended along a second extending direction D2, and the combing and pulling structure 13 is protruded along a protruding direction D3. In detail, the combing and pulling base 12 has a base outer edge part 122, the combing and pulling structure 13 is protruded from the base outer edge part 122 along the protruding direction D3 integrally. In the present embodiment, the base outer edge part 122 is a curved outer edge part. In addition, the combing and pulling base 12 has a base width W. Considering the size of the actual surgical wound, the base width W is ranged between 3 mm to 15 ...

second embodiment

[0072]Please refer to FIG. 10, which is a perspective view showing a periosteal elevator having a tissue combing and pulling structure provided in accordance with the present invention. As shown, the periosteal elevator having a tissue combing and pulling structure 1a comprises a bar 11a, a combing and pulling base 12a, a plurality of combing and pulling structure 13a (only one of them is labelled), an expanded combing and pulling base 14a, and a plurality of expanded combing and pulling structures 15a (only one of them is labelled).

[0073]The bar 11a has a holder 111a, a connection part 112a, and an expanded connection part 113a. The holder 111a is utilized for being held by the dentist. One end of the holder 111a is connected to the connection part 112a and the other end is connected to the expanded connection part 113a. The holder 111a can be made of slip-resistant materials such as rubber, to prevent the precision of the operation from being affected by the wet holder due to the ...

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.

Description

[0001]This application claims the benefit of Taiwan Patent Application Serial No. 107202064, filed Feb. 9, 2018, the subject matter of which is incorporated herein by reference.BACKGROUND OF INVENTION1. Field of the Invention[0002]The present invention is related to a periosteal elevator, and more particularly is related to a periosteal elevator having a tissue combing and pulling structure.2. Description of the Prior Art[0003]Attending with the progress of medical technology, people are more and more relying on medicine. The progress of medical technology also transforms some impossible treatment into possible, such as teeth shaping and full mouth dental implant.[0004]In 1955, Swedish orthopedic surgeon Dr. Per-Ingvar Branemark was conducting research regarding the healing of injured bone, and as a part of the research, Dr. Branemark discovered that titanium shows excellent biocompatibility to the bone and the soft tissue and can be firmly attached to the human body. Thus, Dr. Bran...
