Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a double-edged knife for alveolar ridge mucosa. Background Technology
[0002] In the field of oral medicine, dental implant surgery is widely used in clinical practice as an important means of restoring missing teeth. During the dental implant surgery, the precise cutting and treatment of the alveolar ridge mucosa is crucial. By cutting the alveolar ridge to fully expose the alveolar bone, it is possible to ensure that the implant can be stably placed and achieve good osseointegration with the alveolar bone.
[0003] Currently, single-edged blades are commonly used in alveolar ridge mucosal surgery. However, when used in dental implant surgery, single-edged blades are difficult to use for precise cutting and are prone to repeated cutting. This is mainly because the alveolar ridge mucosa is located in a unique position, with narrow edentulous spaces and closely spaced surrounding teeth. The blade design of single-edged blades is relatively simple, and their flexibility is limited in this complex spatial environment, making it impossible to accurately reach the target area.
[0004] Moreover, the cutting efficiency of existing single-edged blades is still relatively low. In order to achieve the ideal cutting effect, it is often necessary to repeat the cutting action multiple times. However, repeated cutting not only prolongs the operation time and increases the patient's pain, but also causes unnecessary damage to the surrounding healthy tissues, leading to bleeding and other problems. This seriously affects the surgical field of vision and the accuracy of the operation, and thus affects the overall effect of dental implant surgery.
[0005] Based on this, the inventors of this application have developed a double-edged blade for alveolar ridge mucosa. When the blade cuts inside the mouth, it can simultaneously perform cutting and picking actions, eliminating the need to repeatedly cut both sides of the mucosa. This not only improves operational efficiency but also facilitates more precise and uniform cutting, effectively reducing damage to surrounding tissues. Utility Model Content
[0006] This invention provides a double-edged blade for alveolar ridge mucosa, which can solve the technical problems of limited flexibility and the need for repeated cutting when using existing single-edged cutting blades.
[0007] This application provides the following technical solution:
[0008] The alveolar crest mucosa double-edged scalpel includes a double-edged blade, which comprises a cutting section and a mounting section. The cutting section has a V-shaped structure, with the double edges located on both sides of the V-shape, and the included angle of the V-shape is 20-30°. The mounting section of the double-edged blade is provided with a stepped hole for mounting on a handle. The double-edged blade is also provided with a clamping section located in the area between the V-shaped structure of the double-edged blade and the stepped hole. The clamping section is used to cooperate with clamping pliers to achieve disassembly and assembly.
[0009] Beneficial effects:
[0010] 1. Highly efficient cutting and reduced repetitive operations: By designing the cutting blade with a V-shaped double-edged structure, both V-shaped edges can function simultaneously during intraoral cutting. During the cutting process, both cutting and lifting actions can be performed using the blades, allowing for simultaneous treatment of both sides of the mucosa in a single operation, eliminating the need for repeated adjustments and multiple cuts like with a single-edged blade. This significantly improves cutting efficiency, reduces surgical time, and lowers the risk of damage to surrounding tissues, thus promoting better postoperative recovery for the patient.
[0011] 2. Adaptable to narrow oral cavity structures, enhancing operational flexibility: By setting the V-shaped angle within the range of 20-30°, the blade head is relatively narrow. When the blade enters the oral cavity for cutting, the narrower head can more easily penetrate into the narrow alveolar crest area, avoiding excessive interference with surrounding teeth, gums, and other tissues. Compared to existing single-edged blades, it allows for more flexible movement and angle adjustment during use, making it easier for doctors to more accurately control the cutting position and direction, precisely reaching the target area.
[0012] 3. Protecting the cutting edge and extending tool life: Because the cutting tool of this application has a double edge, when clamped by clamping pliers, the cutting edge closest to the clamping pliers is prone to contact and collision with the pliers. However, with the clamping part, the clamping pliers will not directly contact the cutting edge of the tool. During the forceful operation of the clamping pliers, the force generated will be transmitted through the clamping part and will not act on the cutting edge. For example, when installing the tool, if the clamping pliers are directly clamped near the cutting edge, the cutting edge may rub and collide with the clamping pliers when force is applied, resulting in wear, nicks, and other damage to the cutting edge, thereby affecting the cutting performance and service life of the tool.
[0013] Furthermore, the included angle of the V-shape is 25°.
[0014] Beneficial effects: The 25° V-shaped angle gives the blade excellent adaptability to narrow spaces, making the blade head relatively small, which can easily pass through the gaps between teeth and other narrow areas to reach the surgical site smoothly; and compared with blades with too small an angle, the 25° angle ensures cutting force while preventing the cutting direction from being difficult to control due to the head being too sharp.
[0015] Furthermore, the length of the double-edged blade cutting section is 2.5cm, and the length of the mounting section is 2cm.
[0016] Beneficial effects: The 2.5cm cutting length has good versatility. For routine alveolar crest mucosal incision, this length is sufficient to cover the cutting range required for most surgeries, whether it is a small periodontal surgery or mucosal preparation before dental implant surgery. In addition, this length provides sufficient support for the cutting edge during cutting, preventing wobbling or deviation due to excessive cutting edge length. When the doctor applies cutting force, the cutting part can evenly distribute the force to the cutting edge, ensuring a smooth cutting action.
[0017] Furthermore, the clamping part is provided to protrude upward relative to the surface of the double-edged blade.
[0018] Beneficial effects: The upward protrusion of the clamping part provides a clearer and easier-to-reach point of force for the clamping pliers, so that less effort is needed to find a suitable clamping position during clamping, reducing the difficulty of operation and significantly shortening the clamping time; in addition, when the clamping pliers are clamped in the protruding position, a certain safe distance can be maintained between the cutting edge and the clamping pliers to avoid contact damage.
[0019] Furthermore, the surface of the clamping part is provided with an arc-shaped groove for limiting positioning.
[0020] Beneficial effects: The arc groove can fit tightly with the jaws of the clamping pliers, greatly improving the stability during clamping and further ensuring the safe operation of the double-edged blade during installation and removal, avoiding damage to the instrument or accidental injury to the operator due to accidental detachment.
[0021] Furthermore, the surface of the clamping part is provided with anti-slip texture.
[0022] Beneficial effect: It helps to increase the friction between the clamping force and the holding part.
[0023] Furthermore, it also includes a handle, with a mounting block at the front end of the handle, which is used to connect with the stepped hole on the double-edged blade.
[0024] Furthermore, the front end of the mounting block has a U-shaped structure, which is used to fit and connect with one end of the clamping part.
[0025] Beneficial effects: When the double-edged blade is installed on the handle, the front end of the mounting block fits perfectly into the clamping part. This makes it easier for doctors to identify that the blade is installed correctly, and the fit between the two parts further enhances the stability of the connection. Attached Figure Description

[0030] The following detailed description illustrates the specific implementation method:
[0031] The markings in the accompanying drawings include: double-edged blade 1, cutting part 11, mounting part 12, stepped hole 121, clamping part 2, handle 3, mounting block 31, U-shaped structure 311, and clamping pliers 4.
[0032] Example 1
[0033] Double-edged scalpel on alveolar crest mucosa, such as Figure 1 As shown, it includes a double-edged blade 1, which includes a cutting part 11 and a mounting part 12. The cutting part 11 has a V-shaped structure, with the double blades located on both sides of the V-shape. The included angle of the V-shape can be set to 20°, 22°, 25°, 28° or 30°, and in this embodiment, it is preferably 25°.
[0034] Specifically, the length of the cutting part 11 of the double-edged blade 1 is 2.5cm, and the length of the mounting part 12 is 2cm. The length of the cutting part 11 has good versatility. For routine alveolar crest mucosal incision, this length is sufficient to cover the cutting range required for most surgeries, whether it is a small periodontal surgery or mucosal treatment before dental implant surgery.
[0035] The mounting portion 12 of the double-edged blade 1 is provided with a stepped hole 121 for mounting on the handle 3; such as Figure 2 As shown, a mounting block 31 is provided at the front end of the handle 3, which is used to connect with the stepped hole 121 on the double-edged blade 1. Specifically, this embodiment does not improve the installation method of the handle 3 and the blade. Figure 2 The diagram shows the installation of an existing single-edged blade and handle 3. During installation, clamping pliers 4 are used to hold the blade.
[0036] like Figure 3As shown, in this embodiment, the double-edged blade 1 is also provided with a clamping part 2. The clamping part 2 is located in the area between the V-shaped structure and the stepped hole 121 of the double-edged blade 1. The clamping part 2 is used to cooperate with the clamping pliers 4 to achieve assembly and disassembly. Specifically, anti-slip textures can be provided on the surface of the clamping part 2 or the clamping part 2 can be roughened to increase the friction between the clamping pliers 4 and the clamping part 2. In use, this facilitates the operator to quickly locate and find the clamping point, and also improves clamping stability, preventing the clamping pliers 4 from shifting with the blade during installation, thus avoiding collision damage to the cutting edge near the clamping pliers 4.
[0037] This application designs the cutting blade with a V-shaped double-edged structure. During intraoral cutting, both V-shaped edges function simultaneously. The blades can be used for both cutting and lifting motions, allowing for simultaneous treatment of both sides of the mucosa in a single operation. Unlike single-edged blades, this eliminates the need for repeated adjustments and multiple cuts, and a single blade can be used throughout the procedure, improving efficiency and reducing costs. Furthermore, the double-edged blade design allows for more uniform and precise cutting, minimizing damage to surrounding tissues. Compared to existing single-edged blades, it allows for more flexible movement and angle adjustment, enabling surgeons to more accurately control the cutting position and direction, precisely targeting the desired area and increasing surgical success rates.
[0038] Example 2
[0039] The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, the clamping part 2 is provided to protrude upward relative to the surface of the double-edged blade 1; and the front end of the mounting block 31 is provided to be a U-shaped structure 311, which is used to fit and connect with one end of the protruding clamping part 2.
[0040] In this embodiment, the clamping part 2 protrudes upward, which can provide a clearer and easier-to-reach force point for the clamping pliers 4. When the clamping pliers 4 is clamped at the protruding position, a certain safe distance can be maintained between the cutting edge and the clamping pliers 4 to avoid contact damage.
[0041] The front end of the mounting block 31 is set as a U-shaped structure 311. When the double-edged blade 1 is installed on the handle 3, the U-shaped structure 311 at the front end of the mounting block 31 fits into the clamping part 2. On the one hand, it is easy for doctors to identify that it has been installed in place. On the other hand, the two parts fit together, which helps to further enhance the stability of the connection.
[0042] Example 3
[0043] The difference between this embodiment and embodiment two is that the surface of the clamping part 2 is provided with an arc-shaped groove for limiting the position (not shown in the figure); the arc-shaped groove can be closely matched with the jaws of the clamping pliers 4, thereby greatly improving the stability during the clamping process, further ensuring the safe operation of the double-edged blade 1 during the installation and disassembly process, and avoiding the problem of damage to the instrument or accidental injury to the operator due to accidental detachment.
