Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a type of forceps for preventing slippage of dental implant screwdrivers. Background Technology

[0002] Tooth loss or missing teeth is a common oral disease. The results of the Fourth National Oral Health Epidemiological Survey show that the tooth loss rate in my country is 32.3% in the 35-44 age group, 66.2% in the 55-64 age group, and as high as 81.7% in the 65-74 age group. Tooth loss or missing teeth can affect a patient's chewing function, speech function, oral health, and aesthetics. Dental implant restoration has advantages such as good functional restoration and comfortable use, and has become an important means of treating tooth loss or missing teeth.

[0003] Dental implant surgery mainly consists of two stages: the first stage involves implanting the implant into the alveolar bone, and the second stage is dental implant restoration (crown restoration). In clinical procedures, patients are typically in a supine position with their mouths wide open. Furthermore, the implant restoration instruments used in dental implantation are small and varied, making them prone to slipping and falling into the patient's mouth. Without preventative measures, these instruments can be accidentally swallowed, posing a risk to clinical treatment. Among the many instruments easily swallowed, the implant screwdriver is of particular concern, as it is used in the second-stage implant surgery, during implant impression taking, and after implant placement.

[0004] Implant screwdrivers are used frequently and are small in size. Currently, implant screwdrivers used in dental clinics lack professional anti-slip instruments. When using them, dental implant surgeons have to manually rotate them. This can easily cause the implant screwdriver and its disassembly and installation parts, such as the healing cap, to fall into the patient's mouth, threatening the patient's life and health. At the same time, it can also cause great psychological stress to the surgeon.

[0005] Therefore, designing a forceps to prevent the dental implant screwdriver from slipping out and locking it in place, thus avoiding the screwdriver and its components such as the healing cap used for disassembly and installation from slipping out and falling into the patient's mouth and causing safety hazards, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The technical problem to be solved by this invention is: addressing the safety hazard of implant screwdrivers easily falling out during use and being swallowed. The purpose of this invention is to provide a forceps for preventing implant screwdrivers from slipping out, which can fix the implant screwdriver, not only providing convenience for dental implant surgeons, but also effectively avoiding the safety hazard caused by implant screwdrivers and healing caps falling into the patient's mouth.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A forceps for preventing the dental implant screwdriver from slipping includes a forceps handle and a pair of forceps arms extending from the forceps handle. The forceps arms are provided with forceps beaks that are adapted to the upper end of the healing cap, and an anti-slip mechanism is provided between the two forceps beaks to prevent the implant screwdriver from slipping.

[0009] Furthermore, the anti-slip mechanism includes a crossbar on a tweezer beak, and the crossbar has a groove adapted to the implantation screwdriver.

[0010] Furthermore, the anti-slip mechanism also includes a clearance slot on another tweezers beak, through which the crossbar passes when the two tweezers beaks are clamped.

[0011] Furthermore, the groove can be rectangular, circular, oblong, or elliptical.

[0012] Furthermore, the crossbar and the tweezers beak are perpendicular to each other.

[0013] Furthermore, a clamping guide positioning mechanism is provided between the pair of tweezer arms.

[0014] Furthermore, the clamping and guiding positioning mechanism includes a guide positioning rod on one tweezer arm and a guide positioning slot on the other tweezer arm that is adapted to the guide positioning rod; when the two tweezer arms are clamped, the guide positioning rod passes through the guide positioning slot.

[0015] Furthermore, the forceps beak is flat and integrated with the forceps gripping arm.

[0016] Furthermore, the forceps beak and the forceps arm form an angle of 45-75°.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention has a simple structure, a scientific and reasonable design, and is easy to use. By setting an anti-slip mechanism, it can effectively prevent the implant screwdriver from slipping out and falling into the oral cavity, thus avoiding the safety hazard caused by the patient accidentally swallowing the slipped implant screwdriver.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] Example 1.

[0029] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0030] This invention has a simple structure, a scientific and reasonable design, and is easy to use. By setting an anti-slip mechanism, it can effectively prevent the implant screwdriver from slipping out and falling into the oral cavity, thus avoiding the safety hazard caused by the patient accidentally swallowing the slipped implant screwdriver.

[0031] During use, the forceps 1 holds the upper end 11 of the healing cap. When the implant screwdriver 12 is disassembled or assembled on the upper end 11 of the healing cap, it is limited by the anti-slip mechanism to prevent the implant screwdriver and the healing cap from slipping and falling into the oral cavity, thereby effectively avoiding the safety hazard caused by the patient accidentally swallowing the slipped implant screwdriver.

[0032] Example 2.

[0033] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0034] The anti-slip mechanism includes a crossbar 4 on a tweezer beak 1, and the crossbar 4 has a groove 5 that is adapted to the planting screwdriver 12.

[0035] Based on Example 1, this embodiment 2 provides a more preferred structure for the anti-slip mechanism. Specifically, the anti-slip mechanism includes a crossbar 4 mounted on a forceps beak 1, with a slot 5 on the crossbar 4 adapted to the implant screwdriver 12. The implant screwdriver 12 includes an implant screwdriver shaft 9 and an implant screwdriver handle 10. When disassembling or assembling the healing cap, the operator holds the implant screwdriver handle 10, allowing the implant screwdriver shaft 9 to pass through the slot 5 before disassembling or assembling the upper end 11 of the healing cap. The upper end 11 of the healing cap is held by the forceps beak 1 with moderate clamping force, preventing it from becoming too tight. This facilitates the disassembly or assembly of the upper end 11 of the healing cap with the implant screwdriver 12 while effectively preventing the healing cap from slipping out. Thus, even if the operator's hand slips, the implant screwdriver shaft 9 of the implant screwdriver 12, inserted into the slot 5, will not slip into the patient's mouth, effectively preventing the implant screwdriver and healing cap from slipping out and falling into the mouth, causing the patient to swallow them and creating a safety hazard.

[0036] Example 3.

[0037] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0038] The anti-slip mechanism includes a crossbar 4 on a tweezer beak 1, and the crossbar 4 has a groove 5 that is adapted to the planting screwdriver 12.

[0039] The anti-slip mechanism also includes a relief slot 6 on another tweezer 1, through which the crossbar 4 passes when the two tweezer 1 are clamped.

[0040] Based on Example 2, this embodiment 3 provides a more preferred structure for the anti-slip mechanism. Specifically, the anti-slip mechanism further includes a clearance slot 6 on another tweezer beak 1. When the two tweezer beaks 1 are clamped, the crossbar 4 passes through the clearance slot 6. During the disassembly or assembly of the healing cap, the operator holds the handle 10 of the implantation screwdriver, allowing the screwdriver shaft 9 to pass through the slot 5 before disassembling or assembling the upper end 11 of the healing cap. When clamping a healing cap with a narrower diameter, the crossbar 4 can extend out of the clearance slot 6. When clamping a healing cap with a slightly wider diameter, the crossbar 4 only points directly into or only enters the clearance slot 6, but does not extend out of the clearance slot 6. This ensures the flexibility of clamping and is applicable to the assembly and disassembly of healing caps of different sizes, effectively expanding the scope of application.

[0041] Example 4.

[0042] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0043] The anti-slip mechanism includes a crossbar 4 on a tweezer beak 1, and the crossbar 4 has a groove 5 that is adapted to the planting screwdriver 12.

[0044] The slot 5 is rectangular, circular, oblong, or elliptical.

[0045] Based on Example 2, this embodiment 4 provides a more preferred structure for the slot 5, specifically: the slot 5 is rectangular, circular, oblong, or elliptical. This allows for diverse and customized overall structures.

[0046] Example 5.

[0047] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0048] The anti-slip mechanism includes a crossbar 4 on a tweezer beak 1, and the crossbar 4 has a groove 5 that is adapted to the planting screwdriver 12.

[0049] The crossbar 4 and the tweezers beak 1 are perpendicular to each other.

[0050] Based on Example 2, this embodiment 5 presents a more preferred structure between the crossbar 4 and the forceps beak 1, specifically, the crossbar 4 and the forceps beak 1 are perpendicular to each other. The overall structure is simpler and more stable, while also facilitating the operator's observation of the implantation screwdriver 12 disassembling or assembling the upper end 11 of the healing cap.

[0051] Example 6.

[0052] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0053] A clamping guide positioning mechanism is provided between a pair of tweezer arms 2.

[0054] Based on Example 1, Example 6 provides a more preferred structure for the anti-slip forceps for dental implant screwdrivers. Specifically, a clamping guide positioning mechanism is provided between a pair of forceps arms 2. By setting the clamping guide positioning mechanism, the performance of the anti-slip forceps for dental implant screwdrivers can be made more stable, ensuring more stable clamping of the healing cap and anti-slip of the implant screwdriver 12.

[0055] Example 7.

[0056] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0057] A clamping guide positioning mechanism is provided between a pair of tweezer arms 2.

[0058] The clamping and guiding positioning mechanism includes a guide positioning rod 7 on one tweezer arm 2 and a guide positioning slot 8 on the other tweezer arm 2 that is adapted to the guide positioning rod 7; when the two tweezer arms 2 are clamped, the guide positioning rod 7 passes through the guide positioning slot 8.

[0059] Based on Embodiment 6, Embodiment 7 provides a more preferred structure for the clamping and guiding positioning mechanism. Specifically, the clamping and guiding positioning mechanism includes a guiding positioning rod 7 on one clamping arm 2 and a guiding positioning slot 8 on the other clamping arm 2 that is adapted to the guiding positioning rod 7. When the two clamping arms 2 are clamped, the guiding positioning rod 7 passes through the guiding positioning slot 8. With this configuration, when disassembling or assembling the healing cap, the operator holds the handle 10 of the implantation screwdriver, allowing the screwdriver handle 9 to pass through the slot 5 before disassembling or assembling the upper end 11 of the healing cap. When the two clamping arms 2 close to clamp the upper end 11 of the healing cap, the guiding positioning rod 7 enters the guiding positioning slot 8, and the crossbar 4 enters the slot 5 (the crossbar 4 can only enter the slot 5 when the diameter of the healing cap is small; the crossbar 4 does not need to enter the slot 5 when the diameter of the healing cap is large). This ensures the stability of the overall operation and prevents the clamping arms 2 from being subjected to eccentric load, which could cause the tweezers beak 1 to be misaligned and the healing cap to slip off.

[0060] Example 8.

[0061] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0062] The forceps beak 1 is flat and is integrated with the forceps arm 2.

[0063] Based on Example 1, this embodiment 8 provides a more preferred structure for the forceps beak 1, specifically: the forceps beak 1 is flat and integrated with the forceps arm 2. The flat forceps beak 1 makes it easier to hold the healing cap, and the integrated structure with the forceps arm 2 makes the overall structure more stable, ensuring operational stability.

[0064] This invention has a simple structure, a scientific and reasonable design, and is easy to use. By setting an anti-slip mechanism, it can effectively prevent the implant screwdriver from slipping out and falling into the oral cavity, thus avoiding the safety hazard caused by the patient accidentally swallowing the slipped implant screwdriver.

[0065] Example 9.

[0066] like Figure 1-6 As shown, the present invention provides a forceps for preventing the implant screwdriver from slipping, including a forceps handle 3 and a pair of forceps arms 2 extending from the forceps handle 3. The forceps arms 2 are provided with forceps beaks 1 that are adapted to the upper end 11 of the healing cap, and an anti-slip mechanism for preventing the implant screwdriver 12 from slipping is provided between the two forceps beaks 1.

[0067] The forceps beak 1 and the forceps gripping arm 2 form an angle of 45-75°.

[0068] Based on Example 1, this embodiment 9 provides a more preferred structure between the forceps beak 1 and the forceps arm 2, specifically: the forceps beak 1 and the forceps arm 2 form an angle of 45-75°. This design makes it easier for the forceps beak 1 to hold healing caps, etc.

[0069] This invention features a simple structure, a scientifically sound design, and ease of use. By incorporating an anti-slip mechanism, it effectively prevents the implant screwdriver from slipping out and falling into the oral cavity, thus avoiding the safety hazard of patients accidentally swallowing a dislodged screwdriver.

[0070] The long rectangular opening slot on the crossbar in the middle section of the forceps' beak in this invention can fix the implant screwdriver, preventing it from falling out. The opening slot also provides sufficient space for the implant screwdriver, allowing it to be rotated to install and remove the healing cap without obstruction. Simultaneously, both ends of the forceps' beak can grip the upper end of the healing cap, facilitating contact between the implant screwdriver and the healing cap. This allows for convenient installation and removal of the healing cap using the implant screwdriver while it is being fixed in place. This forceps facilitates operation for dental implant surgeons and ensures patient safety.

[0071] The crossbar and its corresponding groove at the beak of the tweezers of this invention, and the crossbar and its corresponding groove at the clamping arm of the tweezers, allow the crossbar to pass through, enabling the clamping of healing caps of different diameters, ensuring the flexibility of clamping, and also expanding the application range of the tweezers.

[0072] The beak of the forceps in this invention is at a certain angle to the forceps arm, making it convenient for dental implant surgeons to use the forceps to operate in the relatively confined space of a patient's mouth. 。

[0073] The long rectangular opening groove on the middle section of the crossbar of the beak of the forceps of this invention can fix the shank of the implant screwdriver and prevent it from slipping out. At the same time, the beak of the forceps is slightly flattened, which can hold the upper end of the healing cap, which is conducive to the contact between the implant screwdriver and the healing cap. This makes it convenient to use the implant screwdriver to install and remove the healing cap while fixing the oral implant screwdriver.

[0074] The crossbar in the middle section of the beak of the tweezers of this invention and its corresponding groove, as well as the crossbar on the inner side of the middle section of the clamping arm and its corresponding groove, can achieve flexible clamping of healing caps of different diameters.

[0075] The beak and clamping arms of the forceps in this invention are at a certain angle, which makes it convenient for dental implant surgeons to operate in the relatively small space of a patient's mouth.
