Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a set of gingival pusher clamps for assisting in oral mucosal flap elevation. Background Technology
[0002] Dental implant surgery has become a routine treatment for restoring missing or damaged teeth. During the surgery, in order to fully expose the alveolar bone in the surgical area and facilitate the implantation of the implant, it is usually necessary to perform a gingival flap, which involves cutting the gingival mucosa and peeling and flipping up the gingival soft tissue flap.
[0003] In areas with missing teeth, especially in the posterior region, the gingival flap lacks support after being raised. Due to its own elasticity, thickness, and infiltration by blood and tissue fluid, it often naturally rebounds or collapses into the bone surface, partially obscuring the surgical field. This makes it impossible for the surgeon to clearly visualize the alveolar ridge crest, the morphology of the bone defect, and important anatomical structures. To maintain a clear surgical field, current procedures typically require an assistant to continuously pull and push the gingival flap using a suction device or retractor. This approach has several inherent drawbacks: it requires an additional assistant to provide continuous support throughout the procedure; the assistant's manual pulling may cause wobbling, and the assistant's fatigue or movement can affect stable exposure of the surgical field. Furthermore, in some confined oral operating spaces, the assistant's hand or instruments may interfere with the surgeon's instruments, affecting the precision and smoothness of the procedure. Utility Model Content
[0004] The purpose of this invention is to provide a gingival retractor clamp kit to assist in oral mucosal flap elevation, thereby solving the technical problems in existing technologies where implantation of missing teeth requires multiple people and is unstable. The various technical effects of the preferred technical solutions provided by this invention are detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a set of gingival forceps for assisting oral mucosal flap elevation, including a clamping body and a clamping body. The clamping body is provided with a first protrusion and the clamping body is provided with a first through hole. The first protrusion is placed in the first through hole so that the clamping body drives the clamping body to open or close. The clamping body includes two clamping arms and an arc-shaped connecting part. Each clamping arm includes a first arc-shaped part and a baffle part connected together. The side of the two first arc-shaped parts that are close to each other is set as a first arc. The arc-shaped connecting part is disposed on the end face of the first arc-shaped part. The baffle part is disposed at one end of the first arc-shaped part. The extending direction of the first arc-shaped part is perpendicular to the extending direction of the baffle part. The baffle part is used to push open and maintain the gingival flap. The first through hole is disposed in the first arc-shaped part. The clamp body includes a fastener and two clamping parts. The fastener is located in the middle of the two clamping parts, so that the two clamping parts are hinged to form the clamp body. The first protrusion is located at the end of the clamping part.
[0006] Preferably, the baffle portion is configured as an arc shape along the height direction.
[0007] Preferably, the cross-sectional area of the baffle portion gradually decreases along the height direction, and the end face of the smaller cross-section of the baffle portion is rounded.
[0008] Preferably, the cross-sectional area at the middle position of the bow-shaped connector is smaller than the cross-sectional area at both ends of the bow-shaped connector.
[0009] Preferably, the outer side of the first arc-shaped portion is configured as a second arc, such that the cross-sectional area of the middle position of the first arc-shaped portion formed by the first arc and the second arc is greater than the cross-sectional area of the two ends of the first arc-shaped portion, and the first through hole is located at the middle position of the first arc-shaped portion.
[0010] Preferably, the clamping part further includes a spring, with both ends of the spring disposed on the two clamping parts and on the handle end of the clamping part.
[0011] Preferably, the clamping part includes a second arc-shaped part, a straight part, and a bent section connected in sequence. The bent section forms an angle with the straight part. A hinge part is provided at the middle position of the straight part. The fastener is installed on the hinge part. A first protrusion is provided at the end of the bent section. The second arc-shaped part forms the handle end. Preferably, the hinge portion includes a first cavity disposed on one of the straight portions and a second protrusion disposed on the other straight portion. The second protrusion is inserted into the first cavity, and the fastener passes through both the side wall of the first cavity and the second protrusion, so that the two straight portions are flush.
[0012] The technical solution provided in this application document has the following beneficial effects: This utility model provides a set of gingival forceps for assisting oral mucosal flap elevation, including a clamping body and a clamping body. The clamping body is provided with a first protrusion and a first through hole. The first protrusion is placed in the first through hole so that the clamping body drives the clamping body to open or close. The clamping body includes two clamping arms and an elastic arc-shaped connecting part. The clamping arms include a first arc-shaped part and a baffle part connected together. The arc-shaped connecting part is located on the upper end surface of the first arc-shaped part, thereby combining the two clamping arms into one. The clamping body includes a fastener and two clamping parts. The fastener is located in the middle part of the two clamping parts, so that the two clamping parts are hinged to form the clamping body. The first protrusion is located at the end of the clamping part.
[0013] This is how it can be achieved. 1. Achieve self-stabilizing fixation: Without the need for an assistant to continuously manually pull on the mucosa of the edentulous area, it can stably clamp and fix itself to the distal adjacent tooth of the missing tooth using its own structure, thus freeing up the doctor's hands.
[0014] 2. Provides a continuous and clear surgical field: Once installed, it provides continuous, stable, and undisturbed surgical field exposure, ensuring that the surgeon has direct vision of the alveolar bone throughout the critical surgical procedure, including the alveolar crest, bone defect morphology, and important anatomical structures.
[0015] 3. Simple and quick operation: Utilizing the operating principle of rubber dam clips familiar to doctors, installation and removal can be completed quickly inside the mouth, significantly improving surgical efficiency.
[0016] 4. Adapts to oral anatomy: The specially designed baffle conforms to the physiological shape of the gums and alveolar bone, effectively and gently pushing apart the gingival flaps on both sides of the alveolar bone in the edentulous area, avoiding excessive traction that could damage the tissues.
[0017] 5. Reduce reliance on human resources: It fundamentally reduces the dependence on additional assistants, making it more feasible and easier for a single doctor to perform such surgeries. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] This specific embodiment provides a set of gingival forceps to assist in the flap elevation of the oral mucosa, in order to solve the technical problems in the prior art that require multiple people to cooperate and are unstable during dental implantation.
[0024] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.
[0025] Reference Figures 1-2 This utility model provides a set of gingival flap-adjusting forceps for assisting oral mucosal flap elevation, including a clamping body 1 and a clamping body 2. The clamping body 2 is provided with a first protrusion 24, and the clamping body 1 is provided with a first through hole 11. The first protrusion 24 is placed in the first through hole 11 so that the clamping body 2 drives the clamping body 1 to open or close. In this way, when people use it, the first protrusion 24 on the clamping body 2 is placed in the first through hole 11 on the clamping body 1, thereby facilitating the movement of the clamping body 2 and the clamping body 1.
[0026] The clamping body 1 includes two clamping arms 12 and an elastic arc-shaped connecting part 13. Each clamping arm 12 includes a first arc-shaped part 121 and a baffle part 122 connected to each other. The arc-shaped connecting part 13 is disposed on the upper end surface of the first arc-shaped part 121, thereby combining the two clamping arms 12 into one unit. The two first arc-shaped parts 121 form a clamping space. To facilitate clamping, the side of the two first arc-shaped parts 121 that is close to each other is set as a first arc 123 to increase the contact area between the first arc-shaped part 121 and the tooth. The baffle part 122 is disposed at one end of the first arc-shaped part 121. The extension direction of the first arc-shaped part 121 is perpendicular to the extension direction of the baffle part 122. That is, if the first arc-shaped part 121 extends laterally, the baffle part 122 extends vertically. The baffle part 122 is used to push open and maintain the gingival flap. A first through hole 11 is disposed on the first arc-shaped part 121.
[0027] The clamp body 2 includes a fastener 21 and two clamping parts 22. The fastener 21 is located in the middle of the two clamping parts 22, so that the two clamping parts 22 are hinged to form the clamp body. That is, one end of the clamp body is used to contact the clamping body 1, and the other end of the clamp body is used to hold the hand to form a handle. In order to facilitate clamping, a first protrusion 24 is provided at the end of the clamping part 22.
[0028] Specifically, during the flap elevation stage of dental implant surgery, the dentist uses standard instruments to cut and elevate the buccal and lingual / palatal gingival flaps of the edentulous area. Holding the handle of the clamp body 2 inwards, the clamping end of the clamp body 1 is opened. The first protrusion 24 on the clamp body 2 is placed within the first through-hole 11. By opening or closing the opening of the clamping end of the clamp body 2, the clamping space of the clamp body 1 is increased or decreased, thus allowing for the clamping of teeth of different sizes. When the clamp body 1 is clamped, the arched connecting part 13 deforms, accumulating elasticity, so that the first arc-shaped part 121 firmly clamps the cervical region of the distal adjacent tooth of the edentulous tooth. The arched connecting part 13 spans the occlusal surface of the distal adjacent tooth, and the two baffle parts 122 naturally extend to both sides of the alveolar ridge crest of the edentulous area, gently pushing open and maintaining the position of the gingival flap, providing clear surgical field exposure. After the surgery, the clamp body 1 is removed using the clamp body 2 again, allowing for easy disassembly of the device.
[0029] In this way, by using adjacent teeth as fulcrums, it can be stably fixed in the oral cavity without the need for continuous manual traction by an assistant, completely freeing the doctor's hands and making it possible for a single doctor to efficiently complete the implant surgery; the clamping body 1 can provide a clear and consistent surgical field throughout the entire operation, avoiding changes in the field of vision caused by fatigue or movement due to manual traction, greatly improving the accuracy and safety of the surgical operation; at the same time, it eliminates the communication and coordination process with the assistant, reducing the possibility of repeated operations due to unclear surgical field, thereby significantly shortening the operation time and improving the overall surgical efficiency.
[0030] In addition, this device is an improvement on the rubber dam clamp structure that dentists are very familiar with. Doctors can easily install and remove it using the matching clamps, making the learning cost extremely low and the learning speed quick.
[0031] The design has been further optimized. The baffle portion 122 is curved along its height, which better separates the gingival flaps and is more ergonomic. Specifically, the baffle portion 122 conforms to the physiological morphology of the gums and alveolar bone, effectively and gently pushing apart the gingival flaps on both sides, avoiding damage to the tissues. The baffle portion 122 has a length of 3-10 mm, a height of 2-4 mm, and a thickness of 0.5-1 mm. Figure 1 As shown, the length direction of the baffle portion 122 is the length direction of the entire clamping body 1, the thickness direction is the left-right direction of the baffle portion 122, and the height direction is the up-down direction of the clamping body 1.
[0032] To further optimize the design and reduce harm to patients, the cross-sectional area of the baffle portion 122 gradually decreases along the height direction, and the end face of the smaller cross-section of the baffle portion 122 is rounded. The thickness of the baffle portion 122 at the position with the smallest cross-section is 0.3-0.5 mm.
[0033] Specifically, to adapt to the anatomical morphology of different tooth positions, the device of this utility model is designed in three models, respectively applicable to the molar region, premolar region, and anterior region. The main differences between these models lie in the dimensions of the clamping body, the curvature of the arched connecting part 13, and the length and height of the baffle part 122, to match the average neck width, crown height, and alveolar ridge morphology of the teeth in each region. According to human permanent tooth anatomy data, the neck width of teeth in the molar region is approximately 7-10 mm, in the premolar region approximately 5-8 mm, and in the anterior region approximately 3-6 mm; the crown height is approximately 4-7 mm in the molar region, 5-8 mm in the premolar region, and 8-12 mm in the anterior region. The specific design is as follows: (1) Molar region model: Applicable to the molar region (such as the first and second molars). The maximum opening distance of the first arc-shaped part 121 under external force is 12-15 mm, and the opening distance of the first arc-shaped part 121 under normal conditions is 7-10 mm, so as to firmly fix it to the wider neck of the molar. The arc radius of the arc-shaped connecting part 13 is 6-9 mm, so as to span the occlusal surface of the molar. The length of the baffle part 122 is 7-10 mm, the height is 3-4 mm, the thickness at the thickest part of the end is 1 mm, and it gradually narrows along the gingival direction to a thickness of 0.5 mm at the end. This design takes into account the characteristics of the wider alveolar ridge and thicker gingival flap in the molar region, providing a larger opening area, ensuring stable exposure of a larger surgical field, and reducing pressure on surrounding tissues.
[0034] (2) Premolar region model: Applicable to the premolar region, the first arc-shaped part 121 has a maximum opening distance of 10-12 mm under external force, and a normal opening distance of 5-8 mm, suitable for the neck of medium-sized premolars. The arc radius of the arc-shaped connecting part 13 is 7-10 mm. The baffle part 122 has a length of 5-8 mm, a height of 2-4 mm, and a thickness of 1 mm at the thickest point at the end, gradually narrowing to a thickness of 0.5 mm at the end along the gingival direction. This model balances stability and precision, adapts to the anatomical structure of the medium-width alveolar ridge in the premolar region, and avoids tissue damage caused by excessive pushing.
[0035] (3) Anterior tooth region model: Applicable to the anterior tooth region (such as incisors and canines). The maximum opening distance of the first arc-shaped part 121 under external force is 8-10 mm, and the opening distance of the first arc-shaped part 121 under normal conditions is 3-6 mm to accommodate the narrow anterior tooth neck. The radius of the arc of the arc-shaped connecting part 13 is 10-14 mm, the length of the baffle part 122 is 3-5 mm, the height is 2-3 mm, the thickness at the thickest point of the end is 0.5 mm, and it gradually narrows along the gingival direction to a thickness of 0.3 mm at the end. This miniaturized design emphasizes precision and gentle thrust, matching the shape of the thinner gingival flap and narrower alveolar ridge in the anterior tooth region, ensuring surgical accuracy and minimizing interference with the aesthetic area.
[0036] These models can be selected according to clinical needs, all of which maintain a one-piece molding and tissue-friendly design to ensure effective exposure of the surgical field in different tooth positions, reduce reliance on assistants, and improve surgical efficiency.
[0037] To further optimize the design, in order to facilitate the deformation of the bow-shaped connecting part 13, the cross-sectional area of the middle position of the bow-shaped connecting part 13 is smaller than the cross-sectional area of the two ends of the bow-shaped connecting part 13, while the cross-sectional area of the two ends of the bow-shaped connecting part 13 is larger, so as to facilitate the connection between the bow-shaped connecting part 13 and the first arc-shaped part 121 and ensure the connection strength between the first arc-shaped part 121 and the bow-shaped connecting part 13.
[0038] To further optimize the design and reduce the harm to the patient caused by the outer side of the first arc-shaped portion 121, the outer side of the first arc-shaped portion 121 is set as a second arc 124. The bending radius of the second arc 124 is smaller than that of the first arc 123, so that the first arc 123 and the second arc 124 form a crescent shape. This makes the cross-sectional area of the middle position of the first arc-shaped portion 121 larger than the cross-sectional area of the two ends of the first arc-shaped portion 121. The first through hole 11 is set at the middle position of the first arc-shaped portion 121 to ensure the overall strength of the clamping body 1.
[0039] To further optimize the design, in order to facilitate the automatic retraction of the clamping part 22, the clamping part 22 also includes a spring 23. The two ends of the spring 23 are fixed on the two clamping parts 22 and are set at the handle end of the clamping part 22, so that the handle end of the clamping part 22 can be automatically retracted.
[0040] In a further optimized design, the clamping part 22 includes a second arc-shaped part 221, a straight part 222, and a bent section 223 connected in sequence. The length direction of the bent section 223 forms an angle with the length direction of the straight part 222, such as... Figure 2As shown, the bent section 223 bends downward to form an angle with the straight section 222. To facilitate hinge connection, a hinge section 224 is provided at the middle position of the straight section 222. The fastener 21 is installed on the hinge section 224, which facilitates the hinge connection of the two clamping sections 22. The first protrusion 24 is provided at the end of the bent section 223, and the second arc-shaped section 221 forms a handle end. To further optimize the design, in order to make the ends of the clamping parts 22 flush with each other, the hinge part 224 includes a first cavity provided on one straight part 222 and a second protrusion provided on another straight part 222. The second protrusion is inserted into the first cavity, and the fastener 21 passes through the side wall of the first cavity and the second protrusion at the same time, so that the two straight parts 222 are flush with each other, ensuring that the first protrusions 24 on the two clamping parts 22 can be placed in the first through hole at the same time.
