Description

Be applied to skin flap ware of getting in oral cavity

Technical Field

The invention relates to the technical field of oral instruments, in particular to a skin flap taking device applied to an oral cavity.

Background

Gingival recession is one of the common diseases faced by oral clinic at present. Traumatic factors such as tooth brushing, dental floss, orthodontics, occlusion, repair and the like, combined with bacterial or viral infection are the main causes of gum recession clinically. Gingival retraction leads to root exposure, sensitive cooling and heating, and insufficient attached gingiva for implantation or/and repair, further affecting the health of the prosthesis or implant.

One type of surgery currently used clinically to address gingival retraction is referred to collectively as a gingival membrane surgery. The method mainly comprises the following steps: free gingival flap surgery, connective tissue flap surgery, lateral transposition flap surgery, coronal replacement flap surgery, frenulum revision surgery, and crown lengthening surgery. Wherein both free gingival flap surgery and connective tissue flap surgery require corresponding tissue to be obtained from the jaw. Due to the complexity and uncertainty of the flap-extraction technique during surgery, it is still currently performed by more annually funded periodontal specialists. Firstly, the maxilla jaw has the largest valve-taking risk of the maxilla aorta palatine, and runs in the deep part of the junction of the soft palate and the hard palate corresponding to the far and middle adjacent surfaces of the second molar of the maxilla. Before the valve-taking operation, the position of the superior palatine artery on the bone surface is required to be positioned; second, palatal tissue is the most commonly used source of tissue procurement in the clinic. The thickness of the connective tissue graft used for root surface coverage varies depending on the clinical situation and generally varies from 1mm to 2 mm. The clinical utility model 15 requires the surgeon to have precise technique to obtain a free gingival flap or sub-epithelial connective tissue flap of uniform thickness. It is common in clinical practice that it is difficult to obtain a sufficient thickness of connective tissue because the gingival flap taken contains too much fat and glandular tissue; third, clinically available gingival or connective tissue grafts are typically cut with a blade, but due to individual anatomical differences, the height of the palatal fornix varies greatly, and the fixed handle does not accommodate better anatomical changes.

Disclosure of Invention

The invention aims to provide a skin flap remover applied to an oral cavity to solve the problems in the prior art.

The technical problem solved by the invention can be realized by adopting the following technical scheme:

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

Referring to fig. 1 to 3, the skin flap remover applied to the oral cavity comprises a handheld portion 1, a Z-shaped adjusting neck 2 attached to the fornix of the human palate in a high-rise manner, a swivel 3 and a blade 4, wherein one end of the handheld portion 1 and one end of the adjusting neck 2 are of an integral structure, the other end of the adjusting neck 2 is connected with the swivel 3, the swivel 3 comprises an internal rotating shaft 31, a swivel base 32 and a blade support 33, the blade support 33 is of a U-shaped structure, the swivel base 32 is arranged at one end of the blade support 33, the swivel base 32 and the blade support 33 are of an integral structure, the internal rotating shaft 31 is fixedly arranged inside the adjusting neck 2 through a first bolt 51, and the blade 4 is fixed at an opening at the end of the blade support 33.

Adjust between neck 2 and the inside pivot 31 direct contact not, be equipped with the annular space of being convenient for adjust between neck 2 and the inside pivot 31, and first bolt 51 wears to establish to the fixed inside pivot 31 of the inside of adjusting neck 2 through the side of adjusting neck 2.

The length specification of the cutting part of blade 4 suits with patient's oral cavity jaw, blade 4 is the cambered surface structure to the inboard crooked of blade support 33, and the front of blade 4 is rectangle loop configuration, and the side is arc mechanism, and it has and the middle fretwork of blade 4, and the downside of middle fretwork department is located to the cutting part of blade 4, and the cutting part of blade 4 up. The cutting part of the skin flap remover can be divided into three specifications, namely 5mm, 10mm and 15 mm.

The width of the blade 4 is adapted to the thickness of the jaw mucous epithelium and fibrous layer, and the width of the blade 4 can adopt several specifications, namely 0.5mm, 1mm, 1.5mm and 2 mm.

First round holes 41 are symmetrically formed in two sides of an opening in the end portion of the blade support 33, second round holes 42 are symmetrically formed in the left side and the right side of a middle hollow portion of the blade, the blade 4 is connected with the blade support 33 through second bolts 52, and the second bolts 52 penetrate through the first round holes 41 and the second round holes 42 in sequence to be fixedly connected.

The handheld portion 1 is of a cylindrical structure, and a wave-shaped structure matched with a hand shape is arranged on the side face of the handheld portion 1.

And third bolts 53 for controlling the vertical adjustment of the rotor 3 are arranged on two outer sides of the blade support 33.

The palatine fornix consists of maxilla, palatine and pterygoid process, and has great palatine foramen, nasal palatine foramen and other important anatomical structures inside. The palatine macropore is 0.5 cm in front of the posterior edge of the hard palate, and is a bone pore which is formed in the left and right borders of the palatine suture to the lateral midline 1/3 of the lateral edge of the second molar, and the anterior palatine nerve vessel is forwards distributed on the periosteum of the back of the cuspid and the gum on the palatine side through the pore. The most important anatomical structures avoided by free gum tissue are clinically taken. According to literature and domestic textbooks, the distribution rate of palatine macropores in the mesial, palatal and distal third molar teeth was 17.22%, 64.59% and 18.18%, respectively. The distance from the palatine foramen and women to the crest of the alveolar ridge (GPF-AC) is (14.02 + -2.69) mm and (12.29 + -2.41) mm. Therefore, the invention designs an intraoral valve extractor.

Free gum transplantation and subepithelial connective tissue transplantation are currently the most effective solutions to address gum recession. The main purpose of the free gingival flap operation is to increase the width of attached gingiva to achieve better plaque control and effectively reduce infection around the prosthesis. Generally comprises 1) preparation of a transplanted area 2) tissue valve taking from an area 3) transplantation of the tissue valve and suturing 4) protection of an operation area and other operation steps. Wherein the critical step is to select tissue flap, select maxillary premolars to palatosilated gingiva of the first molar. Tin foil can be used for cutting the size and the shape of the implanted area as a template for marking the supplied area, and a traditional No. 15 blade is generally used for making a shallow cut, and the gingival tissue is cut off and cut sharply. The thickness of the cut gum tissue is preferably 1.0-1.5 mm, including the keratinized epithelium and a little connective tissue below the keratinized epithelium. The free gum tissue should not be too thick, otherwise the free gum tissue is affected to be tightly attached to the implanted area, which is not beneficial to providing nutrition and easily causes too deep wound surface. In addition, the invention can be applied to the electric flap extractor of the oral cavity, and is more convenient to be applied to clinic; the skin flap taking device can be applied to jaw flap taking alone, and can be used in oral cavities such as a back cushion for tooth grinding and the like; according to the latest literature support, the variety of blades can be further refined.

The invention can adopt the electric flap extractor according to the development of practice and science and technology, and is more convenient to be applied to clinic; in addition, the invention can be applied to the jaw flap taking, and can be used in oral cavities such as a back cushion for tooth grinding and the like.
