Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an impacted wisdom tooth retractor. Background Technology

[0002] Impacted wisdom tooth extraction is a surgical procedure used to remove the outer shell of a wisdom tooth that cannot erupt normally or is partially erupted. The procedure requires cutting the gum and raising a flap to expose the surgical area. It usually requires the use of a power system (usually a high-speed turbine drill) to cut the tooth. During the cutting, a hook is used to pull the lingual gum of the wisdom tooth to raise the flap downward into the oral cavity to expose the surgical area and protect the surrounding important tissues such as the lingual nerve.

[0003] Existing retractors are usually quite large. When removing impacted mandibular wisdom teeth, the simultaneous presence of the power system and the retractor in the oral cavity restricts the field of vision and affects the surgeon's field of vision. At the same time, the buccal fat pad on the buccal side of impacted mandibular wisdom teeth is usually quite prominent in its anatomical structure. When removing impacted mandibular wisdom teeth, the cutting head of the power system can easily roll into the buccal fat pad tissue, causing additional trauma and leading to complications such as bleeding.

[0004] Therefore, there is a need for a retractor for impacted wisdom teeth that is smaller in size and offers better safety. Utility Model Content

[0005] This invention provides an impacted wisdom tooth retractor that can provide a larger surgical field and push aside the buccal fat pad, making the surgical process safer.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An impacted wisdom tooth retractor includes a handle portion, a first connecting portion, and a first working portion that are smoothly connected in sequence; the first working portion is L-shaped and forms a Z-shape with the first connecting portion; the bend of the first working portion is a spherical protrusion, and the end of the first working portion away from the handle portion has a shovel-shaped structure; the included angle at the connection between the first working portion and the first connecting portion and the subtended angle of the first working portion are both obtuse angles.

[0008] Furthermore, the impacted wisdom tooth puller also includes a second connecting part and a second working part connected to the other end of the handle part. The second connecting part has the same structure as the first connecting part, and the second working part has the same structure as the first working part.

[0009] Furthermore, the second working section is centrally symmetrical to the first working section.

[0010] Furthermore, the angle between the first working part and the first connecting part is 10-30° larger than the angle of the L-shaped first working part.

[0011] Furthermore, the angle between the first working part and the first connecting part is 120-150°, and the angle of the first working part is 110-130°.

[0012] Furthermore, the length of the shovel-shaped structure is 1-1.5cm and the width is 0.6-1.0cm; the diameter of the spherical protrusion is 0.8-1.2cm; the length of the two arms of the first working part is 1.5-2.5cm and the width is 0.2-0.5cm; the length of the first connecting part is 1.5-2.5cm and the width is 0.2-0.5cm; and the length of the handle part is 4-8cm and the width is 1-1.5cm.

[0013] Furthermore, the surface of the handle is provided with anti-slip texture.

[0014] Furthermore, the material of the impacted wisdom tooth puller is stainless steel.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The impacted wisdom tooth retractor of this utility model includes a handle part, a connecting part and a working part that are smoothly connected. By setting the first working part to be L-shaped and forming a Z-shape with the first connecting part, the retractor is in the optimal working position and the area of ​​the retractor can be effectively reduced, thereby exposing more surgical field. By setting the bend of the working part to be a spherical protrusion, the spherical protrusion can push away and effectively block the buccal fat pad during use, preventing the cutting head of the power system from rolling into the buccal fat pad tissue, thereby effectively avoiding additional trauma and bleeding complications and improving the safety of the surgery.

[0017] (2) The impacted wisdom tooth retractor of this utility model has a shovel-shaped structure at the end of the first working part away from the handle, which can better open and protect the gums and prevent damage to the gum tissue when the power system cuts the tooth. By setting the included angle at the connection between the first working part and the first connecting part and the opening angle of the first working part to be obtuse angles, the working distance of the retractor can be further extended, making the operation more convenient. It also makes the first working part, the first connecting part and the handle part more dispersed, which is conducive to exposing the surgical field. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 2 This is a schematic diagram of another structure of the impacted wisdom tooth puller of this utility model;

[0021] Wherein: 1-handle part, 2-first connecting part, 3-first working part, 4-shovel-shaped structure, 5-spherical protrusion, 6-anti-slip texture, 7-second connecting part, 8-second working part. Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1 As shown, the present invention provides an impacted wisdom tooth puller, comprising a handle portion 1, a first connecting portion 2, and a first working portion 3 connected in sequence; the first working portion 3 is L-shaped and forms a Z-shape with the first connecting portion 2; the bend of the first working portion 3 is a spherical protrusion 5, and the end of the first working portion 3 away from the handle portion 1 is a shovel-shaped structure 4; the included angle at the connection between the first working portion 3 and the first connecting portion 2, as well as the opening angle of the first working portion 3 (the opening angle of the two arms of the L-shaped first working portion 3), are both obtuse angles. By designing the first working part 3 as an L-shape and forming a Z-shape with the first connecting part 2, the first working part 3 extends outward as much as possible, thereby extending the working distance to place the hook in the optimal working position and effectively reducing the hook area, thus exposing more surgical field. By designing the bend of the first working part 3 as a spherical protrusion 5, during use, this spherical protrusion 5 can push aside the buccal fat pad. Furthermore, because the spherical protrusion 5 has a larger diameter—that is, a wider width relative to the two arms of the L-shaped first working part 3—it can further block the buccal fat pad, preventing the power system cutting head from entraining the buccal fat pad tissue, thereby effectively avoiding additional trauma and bleeding complications and improving surgical safety. By designing the end of the first working part 3 away from the handle part 1 as a shovel-shaped structure 4, which has a certain width and a certain curvature, it can better open and protect the gingiva, preventing damage to the gingival tissue when the power system cuts the tooth. By setting the angle between the first working part 3 and the first connecting part 2 and the angle of the first working part 3 to be obtuse, the working distance of the hook can be further extended, making the operation more convenient. It also makes the first working part 3, the first connecting part 2 and the handle part 1 more dispersed, which is conducive to exposing the surgical field of vision.

[0024] Specifically, such as Figure 2 As shown, the impacted wisdom tooth retractor also includes a second connecting part 7 and a second working part 8 connected to the other end of the handle part 1. The second connecting part 7 has the same structure as the first connecting part 2, and the second working part 8 has the same structure as the first working part 3. By providing a second working part 8 with the same structure at the other end of the handle part 1, the retractor can be used with both ends, thus accommodating both left and right wisdom tooth extractions.

[0025] Specifically, the second working section 8 is centrally symmetrical to the first working section 3. At this time, the bending direction of the second working section 8 is opposite to that of the first working section 3, and the arc direction at both ends is also opposite. This is more in line with human usage habits and makes the operation more convenient when extracting the left and right wisdom teeth.

[0026] Specifically, the angle between the first working part 3 and the first connecting part 2 is 10-30° larger than the angle of the first working part 3. By setting the angle between the first working part 3 and the first connecting part 2 to be larger than its own angle, the working arm between the shovel-shaped structure 4 and the spherical protrusion 5 of the first working part 3 is not parallel to the first connecting part 2, but moves closer to the first connecting part 2. This makes it easier to bring the centers of the handle part 1, the first connecting part 2 and the first working part 3 closer together, making it more convenient to hold the handle part 1 and apply force, and facilitating more accurate control of the applied force.

[0027] Specifically, the angle between the first working part 3 and the first connecting part 2 is 120-150°, and the opening angle of the first working part is 110-130°. Preferably, the angle between the first working part 3 and the first connecting part 2 is 140°, and the opening angle of the first working part 3 is 120°. At this angle, the working volume of the retractor is kept relatively small, thereby exposing more surgical field of view, while also making the operation more flexible and convenient.

[0028] Specifically, the length of the shovel-shaped structure 4 is 1-1.5 cm, and the width is 0.6-1.0 cm; the diameter of the spherical protrusion 5 is 0.8-1.2 cm; the length of the two arms of the first working part 3 is 1.5-2.5 cm, and the width is 0.2-0.5 cm; the length of the first connecting part 2 is 1.5-2.5 cm, and the width is 0.2-0.5 cm; the length of the handle part 1 is 4-8 cm, and the width is 1-1.5 cm. Preferably, the length of the shovel-shaped structure 4 is 1.2 cm, and the width is 1 cm; the diameter of the spherical protrusion 5 is 1 cm; the length of the two arms of the first working part 2 is 2 cm, and the width is 0.3 cm; the length of the first connecting part 2 is 2 cm, and the width is 0.3 cm; the length of the handle part 1 is 5 cm, and the width is 1.5 cm. With these dimensions, the hook adapts well to the human oral cavity, avoiding the problems of an overly small hook causing inconvenience or ineffective protection of the gums and buccal fat pad, as well as an overly large hook affecting the surgical field of vision.

[0029] Specifically, the surface of the handle portion 1 is provided with anti-slip texture 6. By providing anti-slip texture 6, the stability of operation is improved, thereby improving the safety of the surgery.

[0030] Specifically, the retractor for impacted wisdom teeth is made of stainless steel. Using stainless steel makes sterilization of the retractor easier; it also prevents damage to the retractor from the power system, increasing its lifespan; and it more effectively protects the gums and buccal fat pad, improving the safety of the procedure.

[0031] The working principle of this impacted wisdom tooth retractor is as follows: During use, the dentist holds the handle 1, inserts the working part into the patient's mouth, and uses the spade-shaped structure 4 of the working part to pull the lingual gum of the wisdom tooth, causing it to flip into a flap towards the inside of the mouth. At this time, the spherical protrusion 5 pushes aside and blocks the buccal fat pad. Then, the power system is used to cut the wisdom tooth to begin the surgery. After the surgery is completed, the power system is turned off, the retractor is removed, disinfected, and stored for future use.

[0032] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the nature and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.
