Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a novel instrument for periodontal flap surgery. Background Technology

[0002] Periodontal flap surgery is a core surgical procedure in periodontology used to treat moderate to severe periodontitis. Its core objective is to create a flap of gingival soft tissue through a surgical incision, allowing for the thorough removal of tartar, plaque, and inflammatory granulation tissue from the root surface under direct vision. This is followed by alveolar bone reshaping or grafting to control disease progression and promote periodontal tissue regeneration. The success of this surgery directly depends on obtaining a clear, undisturbed surgical field and the efficiency and precision of the surgical instruments in performing key steps such as incision, dissection, debridement, and hemostasis.

[0003] Currently, during periodontal flap surgery, after the dentist cuts open the patient's gums with a scalpel, they use scaling instruments (such as Gracey scalers) to lift the patient's mucoperiosteal flap, facilitating the subsequent removal of periodontal lesions. The dentist also uses a cleaning device to flush the patient's periodontal tissues, ensuring a clean surgical environment. During this process, the patient's gums will bleed continuously due to compression, cutting, and impact. The patient's mouth will also produce a large amount of saliva and used cleaning solution. The continuous accumulation of cleaning solution, saliva, and blood can quickly flood the surgical environment and obstruct the surgical view. At this point, the dentist will use a suction device to remove the waste fluid (cleaning solution, saliva, and blood) from the patient's mouth, thereby ensuring a good surgical view.

[0004] However, this treatment method requires doctors to constantly change surgical instruments, which seriously affects the continuity of the operation, prolongs the operation time, and reduces the efficiency of the operation. Therefore, it is necessary to propose a new type of periodontal flap surgery instrument that can automatically clean and drain the periodontium while treating the patient's gums. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a novel instrument for periodontal flap surgery. Through the design of a rotating cylinder and flap knife, the patient's periodontium is simultaneously cleaned and drained while the gingiva is being treated. This eliminates the need for the doctor to change surgical instruments, effectively ensuring the continuity of the surgery and improving surgical efficiency.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A novel periodontal flap surgery instrument includes a holding cylinder, one end of which is rotatably fitted with a rotating cylinder, which stores a cleaning solution for cleaning the oral cavity; a flap knife is fixedly connected to the end of the rotating cylinder away from the holding cylinder; the side wall of the flap knife has several cleaning holes for spraying the cleaning solution, all of which are connected to the rotating cylinder; the end of the flap knife away from the rotating cylinder has several suction holes for aspirating waste liquid; the holding cylinder is provided with a delivery component for driving the rotating cylinder to deliver the cleaning solution to the cleaning holes and a suction component for driving the suction holes to aspirate waste liquid; the holding cylinder is also provided with an angle adjustment component for adjusting the angle of the flap knife; the delivery component and the suction component are located on both sides of the angle adjustment component, and the delivery component is also used to drive the angle adjustment component and the suction component to operate synchronously.

[0007] The technical principle of the above solution is as follows: During the surgery, the surgeon uses a flap-lifting blade to cut the patient's gums, creating a flap incision. The angle of the flap-lifting blade is then adjusted using an angle adjustment component, and the patient's mucoperiosteal flap is lifted through the incision. While the flap-lifting blade is being adjusted, a delivery component sprays cleaning fluid into the patient's periodontal tissue through the cleaning port. This cleaning fluid cleans the periodontal tissue, removing blood, saliva, and other debris. Simultaneously, a suction component aspirates blood, saliva, and cleaning fluid from the patient's mouth through a suction port, providing the surgeon with a clear surgical field. As the flap-lifting blade rotates, the cleaning and suction ports also rotate synchronously, further cleaning various areas of the patient's mouth and aspirating waste fluids.

[0008] The above approach has the following beneficial effects: 1. In existing technologies, surgeons need to frequently change multiple instruments such as dissectors, irrigators, and suction devices to complete flap surgery, which seriously affects the continuity of the operation, prolongs the operation time, and reduces the efficiency of the operation. Compared with existing technologies, this invention integrates four core functions—gingival incision, gingival flapping, periodontal irrigation, and waste fluid suction and angle adjustment—into one unit through the design of the flap knife and rotating cylinder. Surgeons do not need to frequently change surgical instruments during the operation, avoiding interruptions and time delays caused by instrument switching, making the surgical process more continuous and greatly improving the overall efficiency and smoothness of the operation.

[0009] 2. Through the design of the rotating cylinder, medical staff can initially adjust the rotation angle of the flap knife with their wrist, so that the angle of the flap knife is initially located at the patient's gums. Then, by adjusting the angle of the rotating cylinder, the rotation angle of the flap knife can be finely adjusted, so that the flap knife can be more accurately aligned with the target position, thereby performing more precise treatment and improving the treatment effect.

[0010] 3. In existing technologies, saliva, blood, and cleaning solutions are highly fluid, causing these waste fluids to distribute throughout the patient's oral cavity. This invention, through the design of the flap knife, allows for simultaneous cleaning of the patient's periodontal tissues and suction of waste fluids from the oral cavity while adjusting the flap knife's angle. This eliminates the need for manual adjustment of the instrument angle by medical personnel, effectively reducing the difficulty of oral cleaning and waste fluid removal, and improving the comprehensiveness of these processes. Furthermore, when the rotating cylinder drives the flap knife to rotate, the flap knife only rotates circumferentially without translation, thus preventing cutting during angle adjustment and ensuring the feasibility of angle adjustment.

[0011] Furthermore, the conveying assembly includes a conveying plate that slides laterally against the inner wall of the rotating cylinder. A key rod is fixedly connected to the side of the conveying plate away from the flapping blade. The key rod passes through the rotating cylinder near the holding cylinder and is keyed to it. A driving assembly for driving the key rod to slide laterally within the rotating cylinder is provided inside the holding cylinder. A first regulating assembly for controlling the flow direction of the cleaning fluid is provided inside the rotating cylinder.

[0012] Beneficial effects: This solution, through the design of the key rod, can effectively push the conveyor plate to slide laterally inside the rotating cylinder, thereby realizing the transfer of cleaning fluid.

[0013] Furthermore, the drive assembly includes a sector-shaped gear rotatably fitted inside the grip cylinder, a rack slidably fitted laterally inside the grip cylinder, the gear meshing with the rack, a rotating block rotatably fitted at the end of the rack near the key rod, the rotating block slidably fitted laterally with the inner sidewall of the grip cylinder, and the end of the rotating block away from the rack being fixedly connected to the key rod; a transmission assembly is provided outside the grip cylinder for driving the gear to reciprocate, thereby driving the rack to reciprocate.

[0014] Beneficial effects: This solution, through the design of gears, can effectively drive the rack to move, thereby driving the key rod to move laterally along the inside of the gripping cylinder to achieve transmission.

[0015] Furthermore, the transmission assembly includes a paddle that is fixedly connected to the top of the gear.

[0016] Beneficial effects: This solution, through the design of the paddle, allows doctors to control the rotation angle of the flap knife simply by moving the paddle, while simultaneously controlling the amount of cleaning fluid sprayed and the amount of waste fluid aspirated. It is simple to operate and low in cost.

[0017] Furthermore, the angle adjustment component includes a limiting block fixedly connected to the inner wall of the grip cylinder, and a spiral groove is opened on the surface of the rotating block to slide laterally with the limiting block.

[0018] Beneficial effects: Through the design of the limiting block and the spiral groove, when the key rod drives the rotating block to move laterally, the rotating block will also rotate under the limiting action of the limiting block, thereby adjusting the angle of the flapping blade.

[0019] Furthermore, the first control component includes a first check valve connected to the connection between the rotating cylinder and the cleaning hole, the first check valve being used to deliver the cleaning fluid in the rotating cylinder to the cleaning hole; the side wall of the rotating cylinder is also connected to a second check valve for replenishing the cleaning fluid.

[0020] Beneficial effects: The design of the first one-way valve in this solution can effectively ensure that the cleaning fluid can only be delivered from the rotating cylinder to the cleaning hole, and then used to clean the patient's periodontal tissues through the cleaning hole; the second one-way valve can be used to replenish the cleaning fluid into the rotating cylinder.

[0021] Furthermore, the suction assembly includes a liquid storage tank fixedly connected inside the gripping cylinder; a piston rod is fixedly connected to the side of the rack near the liquid storage tank, and a piston plate is fixedly connected to the end of the piston rod away from the rack inside the liquid storage tank, with the piston plate slidingly engaging with the inner wall of the liquid storage tank; all suction holes are connected to the liquid storage tank, and a second regulating assembly for controlling the flow direction of waste liquid is provided inside the liquid storage tank.

[0022] Beneficial effects: This solution, through the design of the piston rod and piston plate, can drive the liquid storage tank to pump and discharge waste liquid by relying solely on the movement of the rack, effectively reducing the production cost of the device and ensuring the timeliness of waste liquid pumping and discharge.

[0023] Furthermore, the second control component includes a third check valve connected to the connection between the suction port and the storage tank, and a fourth check valve for discharging waste liquid is also connected to the side wall of the storage tank.

[0024] Beneficial effects: The design of the third one-way valve ensures that the waste liquid can only enter the storage tank through the suction hole and will not backflow, thus avoiding contamination of the patient's oral cavity; the design of the fourth one-way valve can effectively discharge the waste liquid from the device.

[0025] Furthermore, a spring is fixedly connected to the end of the key rod near the rotating block, and the end of the spring away from the rotating block is fixedly connected to the rotating cylinder.

[0026] Beneficial effects: Through the spring design, doctors only need to control the pressure applied to the paddle to control the rotation angle of the flap knife, the amount of cleaning fluid sprayed, and the amount of waste fluid aspirated. When the doctor reduces the pressure, the spring will automatically push the key lever and rack back, which in turn will drive the gear and paddle back, eliminating the need for the doctor to return the paddle to its original position and reducing the difficulty of operating the device.

[0027] Furthermore, several lights are fixedly connected to the rotating cylinder near the flap knife side, and control buttons for controlling the lights are embedded in the side wall of the gripping cylinder.

[0028] Beneficial effects: Doctors can activate the lights via control buttons to illuminate the surgical environment and optimize it.

[0029] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The following detailed description illustrates the specific implementation method: Implementation, for example Figure 1 and Figure 2 As shown, a novel periodontal flap surgery instrument includes a holding cylinder 1, with a rotating cylinder 2 rotatably connected to one end of the holding cylinder 1. The rotating cylinder 2 stores a cleaning solution for cleaning the oral cavity (in this embodiment, the liquid storage volume inside the rotating cylinder 2 is designed to be 3-5 mL to meet the cleaning needs of a single area during a single surgery); a flap-lifting blade 3 is welded to the end of the rotating cylinder 2 away from the holding cylinder 1; the side wall of the flap-lifting blade 3 has several cleaning holes 5 for spraying the cleaning solution (the diameter of the cleaning holes 5 is in the range of 0.4 mm; this design can ensure cleaning coverage while generating sufficient flushing force (approximately 0.5-1.0 N / cm²), effectively removing blood clots and plaque, without causing... (Causing damage to soft tissue), the cleaning holes 5 are all connected to the rotating cylinder 2; the flap knife 3 has several suction holes 4 for aspirating waste fluid at the end away from the rotating cylinder 2 (the diameter of the suction holes 4 is approximately 0.25 mm); the holding cylinder 1 is equipped with a delivery component for driving the rotating cylinder 2 to deliver cleaning fluid to the cleaning holes 5 and a suction component for driving the suction holes 4 to aspirate waste fluid; the holding cylinder 1 is also equipped with an angle adjustment component for adjusting the angle of the flap knife 3 (the flap knife 3 can be adjusted to 360° to meet the surgical needs of different angles); the delivery component and the suction component are located on both sides of the angle adjustment component, and the delivery component is also used to drive the angle adjustment component and the suction component to operate synchronously.

[0041] like Figure 3As shown, the conveying assembly includes a conveying plate 8 that slides laterally with the inner wall of the rotating cylinder 2. A key rod 9 is welded to the side of the conveying plate 8 away from the flapping blade 3. The key rod 9 passes through the rotating cylinder 2 near the holding cylinder 1 and is keyed to it. The holding cylinder 1 is provided with a driving assembly for driving the key rod 9 to slide laterally within the rotating cylinder 2.

[0042] like Figure 4 and Figure 5 As shown, the drive assembly includes a fan-shaped gear 14 rotatably engaged within the grip cylinder 1, a rack 13 laterally slidably engaged within the grip cylinder 1, the gear 14 meshing with the rack 13, a rotating block 10 rotatably engaged at the end of the rack 13 near the key rod 9, the rotating block 10 laterally slidably engaged with the inner sidewall of the grip cylinder 1, and the end of the rotating block 10 away from the rack 13 welded to the key rod 9; a transmission assembly is provided outside the grip cylinder 1 for driving the gear 14 to reciprocate, thereby driving the rack 13 to reciprocate; the transmission assembly includes a paddle 22 bolted to the top of the gear 14.

[0043] The rotating cylinder 2 is equipped with a first regulating component for controlling the flow direction of the cleaning fluid; the first regulating component includes a first one-way valve 6 connected to the connection between the rotating cylinder 2 and the cleaning hole 5, and the flow direction of the first one-way valve 6 is from the rotating cylinder 2 to the cleaning hole 5; the side wall of the rotating cylinder 2 is also connected to a second one-way valve 7 for replenishing the cleaning fluid.

[0044] The angle adjustment assembly includes a limiting block 12 welded to the inner wall of the gripping cylinder 1, and a spiral groove on the surface of the rotating block 10 that slides laterally with the limiting block 12.

[0045] Specifically, such as Figure 3 As shown, in the initial state, the paddle 22 is located on the far left.

[0046] At the start of the surgery, the doctor holds the gripping cylinder 1 with their thumb positioned at the lever 22, initially moving the flap knife 3 to the target area. The doctor rotates their wrist to maintain a comfortable position, then flicks the lever 22 to the right. This causes the lever 22 to rotate the gear 14 clockwise, which in turn causes the rack 13 to slide to the left. The rack 13 then pushes the rotating block 10 to the left. Due to the lateral sliding engagement between the limiting block 12 and the spiral groove, the rotating block 10 rotates under the limiting action of the limiting block 12, thereby rotating the key lever 9. Since the key lever 9 is keyed to the rotating cylinder 2, the rotating cylinder 2 and the flap knife 3 rotate synchronously with the key lever 9, precisely adjusting the angle of the flap knife 3 so that its blade is aligned with the target area. The doctor can then begin cutting the patient's gums.

[0047] During the adjustment of the flap knife 3 angle, the rotating block 10 will also push the key rod 9 to move to the left, thereby pushing the delivery plate 8 to move to the left along the inner wall of the rotating cylinder 2, and then discharging the cleaning fluid in the rotating cylinder 2 through the first one-way valve 6 and the cleaning hole 5, thereby cleaning the patient's periodontal tissues (the maximum stroke of the delivery plate 8 can push about 1.0-1.5mL of cleaning fluid out in one stroke. This discharge volume has been optimized to achieve effective rinsing while avoiding excessive accumulation of liquid in the oral cavity).

[0048] When the doctor moves the lever 22 to the left, the rack 13 moves to the right, and the rotating block 10, the key rod 9, and the delivery plate 8 also move to the right. This replenishes the cleaning fluid into the rotating cylinder 2 through the second one-way valve 7 (in this embodiment, the second one-way valve 7 is connected to a container for storing the cleaning fluid). At the same time, the rotating block 10 rotates in the opposite direction, which in turn drives the key rod 9, the rotating cylinder 2, and the flap knife 3 to rotate again and return to their original positions.

[0049] The suction assembly includes a liquid storage tank 17 (with an effective volume of 15-20 mL) welded inside the gripping cylinder 1; a piston rod 15 is bolted to the side of the rack 13 near the liquid storage tank 17, and the end of the piston rod 15 away from the rack 13 extends into the liquid storage tank 17 and is bolted to a piston plate 16, which slides laterally with the inner wall of the liquid storage tank 17; the suction holes 4 are all connected to the liquid storage tank 17.

[0050] The storage tank 17 is equipped with a second control component for controlling the flow direction of waste liquid; the second control component includes a third one-way valve 18 connected to the suction hole 4 and the storage tank 17, and a fourth one-way valve 19 for discharging waste liquid is also connected to the side wall of the storage tank 17.

[0051] Specifically, during the adjustment of the flap knife 3 angle, when the rack 13 moves to the left, it will also pull the piston rod 15 to the left. The piston rod 15 will then pull the piston plate 16 to the left along the reservoir 17, thereby drawing the waste fluid in the patient's oral cavity into the reservoir 17 through the suction hole 4 and the third one-way valve 18. (The single suction stroke of the piston plate 16 can generate a negative pressure of about -10 to -20 kPa. This negative pressure range can effectively remove liquid and small debris, while significantly reducing the risk of clamping or damaging fragile gingival tissue. Its single suction volume is about 1.0-1.5 mL, which matches the single cleaning discharge volume.)

[0052] When the doctor moves the lever 22 to the left, the rack 13 will push the piston rod 15 and piston plate 16 to the right, thereby discharging the waste liquid in the reservoir 17 to the outside of the device through the fourth one-way valve 19.

[0053] A spring 11 is screwed to one end of the key rod 9 near the rotating block 10, and the other end of the spring 11 away from the rotating block 10 is screwed to the rotating cylinder 2.

[0054] Specifically, when the doctor presses the paddle 22 to the right, the spring 11 will compress, generating a reaction force that makes the paddle 22 fit with the doctor's thumb. When the doctor reduces the pressure, the spring 11 will automatically push the key lever 9 and the rack 13 to rebound, which in turn drives the gear 14 and the paddle 22 to rebound. The doctor does not need to manually move the paddle 22 back to its original position, which reduces the difficulty of operating the device and improves the convenience of operation.

[0055] like Figure 2 and Figure 6 As shown, several lighting lamps 20 are fixedly bonded to the side of the rotating cylinder 2 near the flap knife 3, and a control button 21 for controlling the opening and closing of the lighting lamps 20 is embedded in the side wall of the holding cylinder 1.

[0056] Specifically, doctors can activate the lighting 20 via control button 21 to illuminate the surgical environment and optimize it.

[0057] In existing technologies, surgeons need to frequently change multiple instruments such as dissectors, irrigators, and suction devices to complete flap surgery, which severely affects the continuity of the operation, prolongs the operation time, and reduces the efficiency of the operation. Compared with existing technologies, this embodiment integrates the four core functions of gingival incision, gingival flapping, periodontal irrigation, and waste fluid suction and angle adjustment into one unit through the design of the flap knife 3 and the rotating cylinder 2. Surgeons do not need to frequently change surgical instruments during the operation, avoiding operation interruptions and time delays caused by instrument switching, making the operation process more continuous and greatly improving the overall efficiency and smoothness of the operation.

[0058] In this embodiment, the design of the rotating cylinder 2 allows medical staff to initially adjust the rotation angle of the flap knife 3 using their wrist, so that the angle of the flap knife 3 is initially located at the patient's gums. Then, by adjusting the angle of the rotating cylinder 2, the rotation angle of the flap knife 3 can be finely adjusted, so that the flap knife 3 can be more accurately aligned with the target position, thereby performing more precise treatment and improving the treatment effect.

[0059] In existing technologies, saliva, blood, and cleaning solutions are highly fluid, causing these waste fluids to distribute throughout the patient's oral cavity. This embodiment, through the design of the flap knife 3, allows for simultaneous cleaning of the patient's periodontal tissues and suction of waste fluids from the oral cavity while adjusting the angle of the flap knife 3. This eliminates the need for medical personnel to manually adjust the instrument angle, effectively reducing the difficulty of oral cleaning and waste fluid removal, and improving the comprehensiveness of these processes. When the rotating cylinder 2 drives the flap knife 3 to rotate, the flap knife 3 only undergoes circumferential rotation without translation, thus preventing cutting during angle adjustment and ensuring the feasibility of angle adjustment.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
