Description

Technical Field

[0001] The present application relates to the field of oral medical devices, and in particular to a rotary flap forceps used in oral implantology. Background Art

[0002] During oral implant surgery, after an implant is placed in an edentulous area and a healing abutment is installed on the implant, there is usually a gap between the healing abutment and the adjacent tooth bone surface due to a lack of soft tissue to close the wound. Therefore, doctors usually use forceps and a scalpel to cut a piece of soft tissue from the surrounding soft tissue (also known as a rotation flap) to fill the gap between the healing abutment and the bone surface. This can reconstruct the gingival papilla and increase the width of the attached gingiva around the implant.

[0003] At present, when cutting a rotational flap from soft tissue, doctors mostly rely on their clinical operation experience to cut a rotational flap that matches the size and shape of the gap between the healing abutment and the bone surface. However, due to the limited local operating space, the rotational flap cut based on clinical operation experience may be too large or too small. In addition, due to the different shapes of the gap, the requirements for the shape of the rotational flap that needs to be filled in the gap are also different. Therefore, the rotational flap cut by the doctor based on experience cannot completely fit the gap between the healing abutment and the bone surface, affecting the healing effect of the soft tissue around the implant.

DETAILED DESCRIPTION

[0052] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific implementations disclosed below.

[0053] The present application provides a rotary flap forceps for oral implantology, which is combined with the following Figure 1-12d The usage scenarios and structure of the rotary flap forceps for oral implantology provided in this application are described in detail.

[0054] First, let me briefly introduce the process of dental implants. Before the implant surgery, the doctor will conduct a comprehensive examination of the patient's mouth to assess the amount of alveolar bone in the toothless position. Under local anesthesia, the doctor will cut the gum tissue to expose the alveolar bone, use specialized surgical instruments, such as a drill, prepare a cavity in the alveolar bone, implant the implant in the cavity, and install a healing abutment at the same time. Implants are usually made of titanium alloy or other biocompatible materials. The schematic diagram after implantation can be found in Figure 1 and Figure 2 , Figure 1 This is a cross-sectional schematic diagram of implanting an implant in the alveolar bone provided by the present application, such as Figure 1 As shown, the implant 10 is implanted in the alveolar bone. Figure 2 This is a cross-sectional schematic diagram of the implant after the healing abutment is installed, as provided in this application. Figure 2As shown, the healing abutment 20 is installed above the implant 10. After the implant is placed, it takes some time for bone integration. When the implant is completely integrated with the alveolar bone, an artificial crown is made. The artificial crown is designed and made according to the patient's occlusal and aesthetic requirements. After the artificial crown is made, it is fixed on the implant 10 to restore the occlusal function and appearance. Figure 3 , Figure 3 This is a cross-sectional schematic diagram of an artificial crown fixed on an implant provided by the present application, such as Figure 3 As shown, the artificial crown 30 is mounted on the implant 10 .

[0055] The above is a general description of the dental implant process. However, after the implant is placed in the edentulous area and the healing abutment is installed on the implant, there is usually a certain gap between the healing abutment and the adjacent tooth bone surface due to the lack of sufficient soft tissue to close the wound. Therefore, doctors usually use tweezers and a scalpel to cut a portion of soft tissue (also known as a rotation flap) from the surrounding labial or lingual soft tissue to fill the gap between the healing abutment and the bone surface. Currently, when cutting a rotation flap from the soft tissue, doctors mostly rely on experience to cut a rotation flap that matches the size and shape of the gap between the healing abutment and the bone surface. However, the rotation flap cut based on experience may be too large or too small. In addition, due to the different shapes of the gap, the requirements for the shape of the rotation flap that needs to be filled in the gap are also different. Therefore, the rotation flap cut by the doctor based on experience cannot completely fit the gap between the healing abutment and the bone surface, affecting the sealing effect of the soft tissue around the implant, increasing the risk of postoperative infection and the prognosis of the implant.

[0056] Based on this, the present application provides a rotary flap tweezers used in oral implantology, which includes: a tweezers body; the tweezers body includes a first tweezers arm and a second tweezers arm, the first tweezers arm includes a first arm body and a first clamping part, the second tweezers arm includes a second arm body and a second clamping part, the first clamping part and the second clamping part are used to clamp the soft tissue on the buccal or lingual side of the oral cavity; the first clamping part and the second clamping part are both arc-shaped, and the shape of the rotary flap cut from the soft tissue is controlled by the arc-shaped first clamping part and the second clamping part, and the size of the rotary flap is controlled by the hollow structure of the first clamping part and the second clamping part. Therefore, the rotary flap tweezers can effectively control the shape and size of the rotary flap, so that the rotary flap can better fit the gap between the healing base and the bone surface.

[0057] The following combination Figure 4 The specific structure and usage of the rotary flap forceps used in oral implantology are introduced in detail.

[0058] See Figure 4 , Figure 4 Schematic diagram of the structure of the rotary flap forceps for oral implantology provided by the present application. The rotary flap forceps for oral implantology include a forceps body 40, the forceps body 40 including a first forceps arm 401 and a second forceps arm 402, the first forceps arm 401 including a first arm body 4011 and a first clamping portion 4012, the second forceps arm 402 including a second arm body 4021 and a second clamping portion 4022, the first clamping portion 4012 and the second clamping portion 4022 being used to clamp soft tissue on the buccal or lingual side of the oral cavity.

[0059] It should be noted that because the keratinized gingiva on the buccal or lingual side is too thick and the healing abutment cannot be exposed, during the implant surgery, after the implant is placed and the healing abutment is installed, part of the keratinized gingiva on the buccal or lingual side is usually rotated to fill the gap adjacent to the tooth and the implant. This can reconstruct the gingival papilla and increase the width of the attached gingiva around the implant, solving the problem of gingival recession caused by tooth loss, especially the atrophy of the gingival papilla.

[0060] In the present application, the first clamping portion 4012 and the second clamping portion 4022 are both arc-shaped, and the shape of the rotation flap can be controlled by the arc-shaped first clamping portion 4012 and the second clamping portion 4022. The first clamping portion 4012 and the second clamping portion 4022 both have a hollow structure, and the size of the rotation flap can be controlled by the hollow structure. In practical applications, the width of the rotation flap is usually controlled by the hollow structure. The rotation flap is a rotatable soft tissue cut from the soft tissue on the buccal or lingual side of the oral cavity after the first clamping portion and the second clamping portion clamp the soft tissue, according to the arc-shaped edge of the first clamping portion, the arc-shaped edge of the second clamping portion, and the hollow structure. The rotation flap is used to cover the gap between the healing abutment and the bone surface, and the healing abutment is installed on the oral implant.

[0061] The first clamping part 4012 includes: a first clamping arm 4012-1 and a second clamping arm 4012-2, and the first clamping arm 4012-1 and the second clamping arm 4012-2 are separated by the hollow structure of the first clamping part 4012; the second clamping part 4022 includes: a third clamping arm 4022-1 and a fourth clamping arm 4022-2, and the third clamping arm 4022-1 and the fourth clamping arm 4022-2 are separated by the hollow structure of the second clamping part 4022.

[0062] In a specific implementation, the first clamping portion 4012 and the second clamping portion 4022 are both arc-shaped, and correspondingly, the first clamping arm 4012-1, the second clamping arm 4012-2, the third clamping arm 4022-1, and the fourth clamping arm 4022-2 are also arc-shaped. When cutting a rotation flap from soft tissue, the doctor can cut along the arc-shaped edge of the first clamping portion 4012, the arc-shaped edge of the second clamping portion 4022, and the hollow structure according to the size and shape of the rotation flap as needed, or along the arc-shaped edge of the first clamping arm 4012-1, the arc-shaped edge of the second clamping arm 4012-2, the arc-shaped edge of the third clamping arm 4022-1, and the arc-shaped edge of the fourth clamping arm 4022-2, thereby cutting a rotation flap with a certain curvature, which can better fit the gap between the healing abutment and the bone surface. At the same time, cutting the soft tissue in this way can also retain keratinized gingiva of appropriate thickness on the buccal or lingual side, solving the problem that the rotation flap cut by the doctor based on experience is too wide or too narrow, resulting in too little or too thick keratinized gingiva on the remaining buccal or lingual side.

[0063] The first clamping portion 4012 and the second clamping portion 4022 are provided with a sliding structure 4012-3, which is used to adjust the arc dimensions of the first clamping portion 4012 and the second clamping portion 4022 so that the rotation flap cut from the soft tissue according to the arcuate edges of the first clamping portion 4012, the arcuate edges of the second clamping portion 4022, and the hollow structure can cover the gap between the healing abutment and the bone surface. The first clamping portion 4012 and the second clamping portion 4022 are provided with a sliding structure 4012-3, which includes: the first clamping arm 4012-1, the second clamping arm 4012-2, the third clamping arm 4022-1, and the fourth clamping arm 4022-2.

[0064] In actual application, depending on the position of the missing tooth, the size of the implant that needs to be implanted and the corresponding healing abutment are also different. Correspondingly, after the implant is implanted and the healing abutment is installed, the size of the gap between the healing abutment and the bone surface is also different, and thus the size and shape of the soft tissue that needs to be filled are also different. Based on this, the present application provides a sliding structure 4012-3 on the first clamping part 4012 and the second clamping part 4022 to adjust the arc size of the first clamping part 4012 and the second clamping part 4022, so that the rotating flap cut from the soft tissue according to the arc edge of the first clamping part 4012, the arc edge of the second clamping part 4022 and the hollow structure can better cover the gap between the healing abutment and the bone surface. It should be noted that the reason why the shape of the first clamping part 4012 and the second clamping part 4022 is set to be arc-shaped is to control the shape of the rotating flap to be half-moon-shaped. Generally, according to the diameter of the healing base, in order to ensure that the shape of the rotational flap cut using the rotational flap forceps exactly matches the shape of the healing base, the sliding structure 4012-3 can adjust the arc size of the first clamping part 4012 and the second clamping part 4022 to 3mm, 5mm, 7mm, and the width of the cut rotational flap is usually 2mm, 3mm, 5mm.

[0065] Of course, in the present application, since the first clamping part 4012 includes the first clamping arm 4012-1 and the second clamping arm 4012-2, and the second clamping part 4022 includes the third clamping arm 4022-1 and the fourth clamping arm 4022-2, the first clamping arm 4012-1, the second clamping arm 4012-2, the third clamping arm 4022-1 and the fourth clamping arm 4022-2 are all provided with a sliding structure 4012-3. The present application takes the sliding structure provided on the first clamping arm 4012-1 as an example for introduction. The sliding structures provided on the second clamping arm 4012-2, the third clamping arm 4022-1 and the fourth clamping arm 4022-2 are similar to the sliding structure on the first clamping arm 4012-1 and will not be elaborated here.

[0066] The sliding structure 4012-3 includes a first sliding plate 4012-31 and a second sliding plate 4012-32. The first sliding plate 4012-31 is provided with a sliding rail 4012-311, and the second sliding plate 4012-32 is provided with a sliding groove 4012-321 that matches the sliding rail. Figure 5 , Figure 5This is a partially enlarged view of the first clamping arm of the rotary flap forceps for oral implantology provided by this application. The sliding structure 4012-3 divides the first clamping arm 4012-1 into a front clamping arm 4012-11 and a rear clamping arm 4012-12. The first slide 4012-31 is connected to the front clamping arm 4012-11, and the second slide 4012-32 is connected to the rear clamping arm 4012-12. The first slide 4012-31 is provided with a plurality of positioning protrusions 4012-312, and the second slide is provided with positioning holes 4012-322 that match the positioning protrusions 4012-312. Figure 6 and Figure 7 , Figure 6 is a structural diagram of the first sliding piece in the sliding structure provided by this application, Figure 7 Schematic diagram of the structure of the second slide in the sliding structure provided in the present application. When the sliding structure 4012-3 adjusts the arc size of the first clamping arm 4012-1, the first slide 4012-31 and the second slide 4012-32 are slid so that the positioning protrusion 4012-312 on the first slide 4012-31 matches the positioning hole 4012-322 on the second slide 4012-32 according to the arc size requirement.

[0067] It should be noted that since the sliding structure 4012-3 is arranged on the arc-shaped first clamping part 4012 and the second clamping part 4022, the shapes of the first slide 4012-31 and the second slide 4012-32 are also arc-shaped. After an arc-shaped slide rail 4012-311 is provided on the first slide 4012-31 and an arc-shaped slide groove 4012-321 is provided on the second slide 4012-32, the arc size can be adjusted by sliding cooperation between the slide rail 4012-311 and the slide groove 4012-321, so that rotating petals of different sizes and shapes can be cut according to actual needs.

[0068] In specific implementation, the present application further provides a blade slot 4013 on the inner side surface of the first clamping arm 4012-1 facing the upper surface of the hollow structure, the inner side surface of the lower surface of the first clamping arm 4012-1, and the inner side surface of the lower surface of the second clamping arm 4012-2 facing the hollow structure, see Figure 8a and Figure 8b , Figure 8a This is a schematic diagram of the installation position of the blade slot provided in this application. Figure 8bSchematic diagram of a cross section of the blade slot provided in this application. The blade slot 4013 is used to accommodate a blade 4014. The tough portion of the blade 4014 faces the inner side of the first clamping arm 4012-1 and the second clamping arm 4012-2. The blade 4014 is used to cut soft tissue and can specifically be a tough cutting blade. The bottom end of the blade 4014 is provided with a blade base 4015 that matches the blade slot 4013. The blade base 4015 is slidably connected to the blade slot 4013. See Figure 8c and Figure 8d , Figure 8c is a schematic diagram of a cross section of a blade provided in this application, Figure 8d This is a cross-sectional schematic diagram of the blade provided in this application installed in the blade slot.

[0069] It should be noted that, in order to realize automatic cutting of the rotating flap, the embodiment of the present application is described as follows: the outer side surface of the first arm body 4011 faces the buccal side, and the inner side surface faces the lingual side. A blade slot 4013 is provided on the inner side surface of the upper surface of the first clamping arm 4012-1 facing the hollow structure, the inner side surface of the lower surface of the first clamping arm 4012-1, and the inner side surface of the lower surface of the second clamping arm 4012-2 facing the hollow structure (the position of the blade slot is Figure 8a At the thickened center line, the opening of the blade slot faces the tongue side, i.e. Figure 8a In the figure, the blade 4014 is installed in the blade slot 4013 when soft tissue needs to be cut. The length of the blade 4014 can be 2 mm and the width of the blade can be 3 mm. In specific use, the blade 4014 can be placed at a designated position according to the width of the rotary flap to be cut. For example, if a rotary flap with a width of 2 mm needs to be cut, the blade 4014 is installed in the blade slot 4013 on the inner side of the lower surface of the second clamping arm 4012-2 facing the hollow structure; if a rotary flap with a width of 3 mm needs to be cut, the blade 4014 is installed in the blade slot 4013 on the inner side of the upper surface of the first clamping arm 4012-1 facing the hollow structure; if a rotary flap with a width of 5 mm needs to be cut, the blade 4014 is installed in the blade slot 4013 on the inner side of the lower surface of the first clamping arm 4012-1, so that rotary flaps with widths of 2 mm, 3 mm, and 5 mm can be automatically cut.

[0070] The blade slot 4013 is also provided with a baffle 4018, which is slidably connected to the blade slot 4013. The inner side of the first arm 4011 is provided with a plurality of control keys 4016, which are used to control the position of the baffle 4018 so that the baffle 4018 limits the blade 4014 to a preset position. The outer side of the first arm 4011 is provided with a start cutting button 4017, which is connected to a drive structure (not shown in the figure) that is connected to the blade base 4015. When the start cutting button 4017 is activated, the blade 4014 is driven by the drive structure to slide along the blade slot 4013 to automatically cut soft tissue. Figure 8e and Figure 8f , Figure 8e This is a schematic diagram of the control keys on the inner side of the first arm provided in this application. Figure 8f This is a schematic diagram of the cutting start button on the outer side of the first arm provided in this application.

[0071] It should be noted that in order to achieve automatic cutting, a start cutting button 4017 is set on the outer side of the first arm 4011. The start cutting button 4017 is connected to a driving structure (not shown in the figure), and the driving structure is connected to the blade base 4015. When soft tissue needs to be cut, the doctor can start the cutting button 4017. When the start cutting button 4017 is triggered, the blade 4014 slides along the blade slot 4013 under the drive of the driving structure, thereby achieving automatic cutting of soft tissue.

[0072] In order to enable the blade 4014 to cut rotating petals of lengths of 3mm, 5mm, and 7mm, a baffle 4018 is further provided in the blade slot 4013. The baffle 4018 is slidably connected to the blade slot 4013. Due to the different lengths of the rotating petals to be cut, the embodiment of the present application also sets different gears for the baffle 4018, and the baffle 4018 is set to different gears via a control key 4016. In specific implementation, a plurality of control keys 4016 are provided on the inner side of the first arm 4011. The control keys 4016 are used to control the position of the baffle 4018 so that the baffle 4018 limits the blade 4014 to a preset position. Figure 9a 、 Figure 9b and Figure 9c , Figure 9a The schematic diagram of the control key provided in this application controlling the baffle to slide to the first preset position, Figure 9b The schematic diagram of the control key provided in this application controlling the baffle to slide to the second preset position, Figure 9c The present application provides a schematic diagram of a control key controlling the baffle to slide to a third preset position. For example, when a rotating flap with a length of 3 mm needs to be cut, the trigger Figure 9aWhen the rotary flap with a length of 5 mm needs to be cut, the control key 4016 at the position shown in FIG is triggered. Figure 9b When the rotary flap with a length of 7 mm needs to be cut, the control key 4016 at the position shown in FIG is triggered. Figure 9c The control key 4016 is located at the position shown in the figure, so that the baffle 4018 can be used to position the rotating flap with a length of 3mm, 5mm, and 7mm, and then the cutting button 4017 is triggered to start, thereby realizing automatic cutting of soft tissue.

[0073] It should be noted that the embodiment of the present application is described by taking the outer side of the first arm 4011 facing the buccal side and the inner side facing the lingual side as an example. In actual application, when the outer side of the second arm 4021 faces the buccal side and the inner side faces the lingual side, the blade slot 4013 needs to be set on the inner side of the upper surface of the third clamping arm 4022-1 facing the hollow structure, the inner side of the lower surface of the third clamping arm 4022-1, and the inner side of the lower surface of the fourth clamping arm 4022-2 facing the hollow structure. Correspondingly, the settings of the blade 4014, the baffle 4018, the control key 4016, and the start cutting button 4017 are set in accordance with the methods in the above embodiments and will not be described in detail here. In addition, the specific method of sliding connection between the components in the above process is not specifically limited. For example, a slide rail can be set on one of the components, and a slide groove matching the slide rail can be set on the other corresponding component. As long as the method can achieve sliding connection between the components, it is within the scope of protection of this application.

[0074] In a specific implementation, the arc dimensions of the first clamping portion 4012 and the second clamping portion 4022 are determined based on the diameter of the upper surface of the healing abutment 20. Once the healing abutment 20 covering the implant 10 is determined, the arc dimensions of the required rotational flap are essentially determined. The arc dimensions can then be adjusted based on actual needs by adjusting the sliding structure, thereby cutting a rotational flap along the arc edge to match the diameter of the healing abutment. In actual applications, the diameters and heights of different healing abutments are also different. For example, the diameter of a healing abutment can be 3.3mm, 3.6mm, 4.8mm, 5.5mm, 7.2mm, etc. The corresponding height of a healing abutment with a diameter of 3.3mm is generally 3.5mm and 5mm; the corresponding height of a healing abutment with a diameter of 3.6mm is generally 2mm, 3.5mm, and 5mm; the corresponding height of a healing abutment with a diameter of 4.8mm is generally 2mm, 3.5mm, and 5mm; the corresponding height of a healing abutment with a diameter of 5.5mm is generally 2mm, 4mm, 6mm, and 7mm; the corresponding height of a healing abutment with a diameter of 7.2mm is generally 2mm, 4mm, and 6mm. During specific use, the doctor can choose the appropriate implant according to the position of the missing tooth. After determining the implant, the appropriate type of healing abutment can be selected according to the size of the implant.

[0075] In the present application, the distance between the two arcuate edges of the first clamping arm 4012-1 can be 2 mm, the distance between the two arcuate edges of the second clamping arm 4012-2 can be 2 mm, and the distance of the hollow structure between the first clamping arm 4012-1 and the second clamping arm 4012-2 can be 1 mm; the distance between the two arcuate edges of the third clamping arm 4022-1 can be 2 mm, the distance between the two arcuate edges of the fourth clamping arm 4022-2 can be 2 mm, and the distance of the hollow structure between the third clamping arm 4022-1 and the fourth clamping arm 4022-2 can be 1 mm.

[0076] In specific implementation, since the distance between the two arc-shaped edges of the first clamping arm 4012-1 and the second clamping arm 4012-2 can be 2 mm, and the distance between the hollow structure of the first clamping arm 4012-1 and the second clamping arm 4012-2 can be 1 mm, when the doctor cuts the rotating flap along the arc-shaped edge, he can cut a rotating flap with a width of 2 mm, 3 mm, or 5 mm according to actual needs.

[0077] It should be noted that since there is a hollow structure between the first clamping arm 4012-1 and the second clamping arm 4012-2, and there is a hollow structure between the third clamping arm 4022-1 and the fourth clamping arm 4022-2, the tweezers can also be used as suturing tweezers. When in use, the suture needle can be inserted into and through the tissue through the hollow structure, and then the operation can be performed according to the suturing technique.

[0078] See Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the tooth structure of the rotary flap forceps for oral implantology provided in this application. Figure 11 It is a partial enlarged schematic diagram of the tooth structure of the rotary flap forceps for oral implantology provided by the present application. The inner ends of the first clamping part 4012 and the second clamping part 4022 are respectively provided with tooth structures 4012-4, wherein, if the number of tooth structures provided at the inner end of the first clamping arm 4012-1 in the first clamping part 4012 is 1, correspondingly, the number of tooth structures provided at the inner end of the third clamping arm 4022-1 in the second clamping part 4022 opposite to the first clamping arm 4012-1 is 2; if the number of tooth structures provided at the inner end of the first clamping arm 4012-1 in the first clamping part 4012 is 2, correspondingly, the number of teeth provided at the inner end of the third clamping arm 4022-1 in the second clamping part 4022 opposite to the first clamping arm 4012-1 is 1.

[0079] In a specific implementation, a tooth-like structure 4012-4 can also be provided at the inner ends of the first clamping portion 4012 and the second clamping portion 4022, specifically at the inner ends of the first clamping arm 4012-1, the second clamping arm 4012-2, the third clamping arm 4022-1, and the fourth clamping arm 4022-2. By providing tooth-like structures at the ends, soft tissue can be clamped more stably. It should be noted that in order to prevent the cut rotation flap from slipping during cutting or transfer, the number of tooth-like structures at the end of the clamping arm can be set to 1, and the number of tooth-like structures at the end of the other clamping arm opposite to the clamping arm can be set to 2. For example, the first clamping arm 4012-1 and the third clamping arm 4022-1 are arranged opposite each other, and the number of tooth structures provided on the inner end of the first clamping arm 4012-1 can be 1, and the number of tooth structures provided on the inner end of the third clamping arm 4012-3 can be 2. Of course, the number of tooth structures provided on the inner end of the first clamping arm 4012-1 can also be 2, and the number of tooth structures provided on the inner end of the third clamping arm 4012-3 can be 1. By providing tooth structures, and providing different numbers of tooth structures on the opposing clamping arms, the two can be meshed more tightly, thereby more stably clamping soft tissue.

[0080] In the present application, a clamping segment scale (not shown in the figure) starting from the end of the first clamping portion 4012 and the second clamping portion 4022 is provided on the outer side surface of the first clamping portion 4012 and the second clamping portion 4022. The clamping segment scale identifies the arc size. By setting this scale, it is convenient for the doctor to refer to the cutting size when cutting soft tissue. A rib (not shown in the figure) for marking the starting incision position of the soft tissue is provided on the outer side surface of the first clamping portion and the second clamping portion. The rib is used to mark the starting point of cutting the soft tissue. When used, the doctor can start cutting along the arc edge from the clamping segment scale and cut the adapted rotation flap size according to actual needs and the clamping segment scale.

[0081] The following combination Figure 12a-12d This article describes how to use rotary flap forceps to cut a rotational flap and how to fill the gap between the tooth and the healing abutment with the rotational flap.

[0082] See Figure 12a , Figure 12a This application provides a top view of the implant after the healing abutment is installed on the implant. After the implant is placed in the edentulous area and the healing abutment is installed on the implant, there is a certain gap between the healing abutment and the adjacent tooth bone surface due to the lack of sufficient soft tissue. Figure 12b , Figure 12b This is a schematic diagram of using rotary flap forceps and a scalpel to cut a rotary flap from soft tissue as provided by the present application. According to the diameter of the healing base and the size and shape of the gap between the healing base and the tooth, the arc size of the rotary flap forceps is adjusted by the sliding structure, and the rotary flap forceps and the scalpel are used to cut a rotary flap that matches the size and shape of the gap from the surrounding soft tissue. During the specific cutting, the first clamping part and the second clamping part of the rotary flap forceps are placed on the soft tissue to be cut. One way can be to use a scalpel to cut along the arc edge of the first clamping part, the arc edge of the second clamping part and the hollow structure to cut a rotary flap of a preset size. For example, a rotary flap of 2mm, 3mm, or 5mm can be cut. Another way can be to use the rotary flap forceps provided by the present application that can realize the automatic cutting function, and to trigger the start cutting button 4017 to realize automatic cutting of soft tissue. It should be noted that, taking the example of cutting a rotary flap with a width of 3mm and a length of 3mm, Figure 12b In the embodiment, the blade slot 4013 can be specifically provided on the inner side of the upper surface of the first clamping arm 4012-1 facing the hollow structure, and the blade 4014 faces the tongue side (vertically inward from the paper); by triggering Figure 9aThe control key 4016 is positioned as shown in the figure to fix the baffle 4018 at the first preset position. Then, the start cutting button 4017 is triggered, and the blade 4014 slides from the end (right end) of the first clamping arm 4012-1 to the left, thereby automatically cutting a rotating flap with a width of 3 mm and a length of 3 mm.

[0083] See Figure 12c , Figure 12c This is a schematic diagram of a rotation flap cut from soft tissue provided in this application. After the rotation flap is cut, it is grasped with a rotation flap forceps and rotated to fill the gap between the healing abutment and the tooth. Figure 12d , Figure 12d This is a schematic diagram provided in the present application of using rotary flap forceps to fill the gap between the tooth and the healing base with a rotary flap. The rotary flap forceps can be used to cut a rotary flap that matches the size and shape of the gap, so that the rotary flap can better cover the gap between the healing base and the tooth bone surface.

[0084] The above is an overall introduction to the rotary flap forceps for oral implantology provided by the present application. The rotary flap forceps for oral implantology provided by the present application can control the shape of the rotary flap cut from the soft tissue through the arc-shaped first clamping part and the second clamping part, and control the size of the rotary flap through the hollow structure of the first clamping part and the second clamping part. Therefore, the rotary flap forceps can effectively control the shape and size of the rotary flap, so that the rotary flap can better fit the gap between the healing base and the bone surface.

Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims of the present application.
