Description

Technical Field

[0001] This disclosure relates to the field of dental implant technology, and more particularly to a socket wrench and implant tool kit for locking composite abutments. Background Technology

[0002] The dental implant procedure involves the following steps: First, a composite abutment of the appropriate size is selected based on the perforation parameters. Then, the composite abutment is installed into the corresponding implant site using a screwdriver. At this point, to ensure stability between the composite abutment and the implant, a socket wrench is used to tighten the composite abutment. The socket wrench mainly consists of two parts: a sleeve that fits over the top of the composite abutment, and a wrench that fits over the sleeve. The combination of the sleeve and the wrench forms the aforementioned socket wrench.

[0003] Currently, in dental implant procedures, the conventional sleeve and wrench are all linear in structure. During tightening, the sleeve and the composite abutment are vertically aligned and coaxial, while the wrench is horizontal and vertically connected to the top of the sleeve. When the implant is located in the anterior part of the mouth, this sleeve-wrench structure allows for easy access to the operating area and provides sufficient space for tightening the composite abutment. However, when the implant is located in the posterior part of the mouth or in other special locations, this sleeve-wrench structure makes it difficult to access the operating area and operate within the confined space of the posterior part of the mouth. This makes tightening the composite abutment difficult, affecting the tightening effect. Furthermore, to adjust the wrench position and angle within the limited space, the operator often needs to maintain an unnatural hand posture for extended periods, which can easily lead to hand fatigue, increase the risk of operational errors, and prolong the operation time.

[0004] In addition, the socket wrench needs to be adjusted to fit different sizes and models of composite abutments, resulting in a large variety of instruments in the implantation tool kit, which is not conducive to instrument counting during and after the operation. Summary of the Invention

[0005] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, in the first aspect of this disclosure, a socket wrench for locking a composite base is provided, comprising a socket and a wrench;

[0007] The sleeve includes a cylindrical body, a manual grip, and a torque-applying part. The cylindrical body is detachably connected to the lower end of the manual grip, the torque-applying part is connected to the upper end of the manual grip, and the end of the cylindrical body away from the manual grip is configured as a connecting hole to fit onto the top of the composite base. The torque-applying part is configured as a polygonal connector for wrench connection.

[0008] The wrench includes a socket section and a gripping and force-applying section. The front end of the socket section is provided with a socket hole that matches the polygonal connector. The socket section and the gripping and force-applying section are connected at an obtuse angle.

[0009] In one feasible implementation, the manual grip portion is configured as a cylinder, the diameter of the manual grip portion is greater than or equal to the diameter of the polygonal connector, and multiple anti-slip grooves are evenly distributed on the circumferential sidewall of the manual grip portion.

[0010] In one possible implementation, the edge of the polygonal connector away from the manual grip is configured as a curved surface.

[0011] In one feasible implementation, a quick-change structure is provided between the lower end of the cylinder and the manual grip, wherein the quick-change structure is configured as a hexagonal magnetic slot or a spring bead positioning component.

[0012] In one feasible implementation, a plurality of lighting sources are provided on the end face of the manual grip portion connected to the cylinder body along the circumference of the manual grip portion, and the plurality of lighting sources are focused on the end of the cylinder body.

[0013] In one feasible implementation, the number of wrenches is set to two, namely a first wrench and a second wrench. The gripping and force-applying section of the first wrench is deflected to the right relative to the socket section to form an obtuse angle connection with the socket section, and the gripping and force-applying section of the second wrench is deflected to the left relative to the socket section to form an obtuse angle connection with the socket section. The first wrench and the second wrench are used selectively only.

[0014] In one feasible implementation, the middle and rear ends of the gripping force application section are fitted with a soft grip sleeve to increase grip friction.

[0015] A second aspect of this disclosure provides a planting tool kit including the aforementioned socket wrench for locking composite abutments.

[0016] Compared with the prior art, this disclosure has at least the following advantages: the cylinder body of this disclosure is detachably connected to the lower end of the manual grip, so as to facilitate the replacement of different models of cylinder bodies and thus increase the usability of this disclosure;

[0017] The wrench disclosed herein has an obtuse-angled connecting section and a gripping and force-applying section, thereby making the wrench a non-linear structure. When applying force, especially when the implant site is in the posterior part of the oral cavity or in a special position, the non-linear structure allows the sleeve wrench to easily reach the operating area and has sufficient operating space, thereby accurately and quickly locking the composite abutment, reducing the difficulty of operation and hand fatigue, improving surgical efficiency and quality, and providing stronger support for the smooth performance of dental implant surgery.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0029] Currently, after the composite abutment is installed in the corresponding implant site, a socket wrench is needed to lock the composite abutment in order to ensure the stability between the composite abutment and the implant. When the implant site is located in the posterior part of the oral cavity or in a special position, the existing socket wrench has a straight sleeve and wrench structure, which makes it difficult to conveniently reach the operating area in the posterior part of the oral cavity or in a special position and makes it difficult to operate in the narrow space of the posterior part of the oral cavity. Based on this, the present disclosure provides a socket wrench and tool box for locking composite abutments.

[0030] The sleeve of this invention is detachably connected to the lower end of the manual grip, facilitating the replacement of different sleeve models and thus increasing the adaptability of this invention. The wrench of this invention has an obtuse-angled socket section and a gripping force application section, allowing the socket wrench to easily reach the operating area and operate within the confined space of the posterior oral cavity. This enables precise and rapid tightening of the composite abutment, reducing operational difficulty and hand fatigue, improving surgical efficiency and quality, and providing stronger support for the successful implementation of dental implant surgery.

[0031] The following is a detailed description of the socket wrench used for locking composite bases through specific embodiments:

[0032] Reference Figures 1 to 5 As shown, a socket wrench for locking a composite base is provided in the first aspect of this disclosure, comprising a socket 10 and a wrench 20, wherein the socket 10 includes a body 101, a manual grip portion 102, and a torque applying portion 103, the body 101 being detachably connected to the lower end of the manual grip portion 102, the torque applying portion 103 being connected to the upper end of the manual grip portion 102, and the body 101 being located away from the manual grip portion 102. One end is configured as a connecting sleeve 1011 to fit onto the top of the composite base (not shown), while the torque applying part 103 is configured as a polygonal connector 1031 for the wrench 20 to be fitted. The wrench 20 includes a fitting section 201 and a gripping force applying section 202. The front end of the fitting section 201 is provided with a fitting hole 2011 that matches the polygonal connector 1031. The fitting section 201 and the gripping force applying section 202 form an obtuse angle connection. It should be noted that the top of the composite base mentioned in this disclosure is configured as an external hexagonal head, which is fitted onto the connecting sleeve 1011.

[0033] The cylinder 101 of this disclosure is detachably connected to the lower end of the manual grip 102 to facilitate the replacement of different models of cylinder 101, thereby increasing the applicability of this disclosure. When the cylinder 101 is connected to the manual grip 102, the central axes of the cylinder 101, the manual grip 102, and the torque application part 103 overlap, ensuring the precision of tightening the composite base and its auxiliary components. Furthermore, the wrench 200 has been structurally optimized and improved, constructed with a socket section 201 and a gripping and applying section 202 featuring an obtuse angle connection, thereby facilitating quick and precise tightening of the composite base in the posterior part of the oral cavity or other special locations.

[0034] Specifically, to accommodate the use of this disclosure during the locking process, the detachable connection between the cylindrical body 101 and the lower end of the manual grip 102 avoids the use of mating threaded connections. Instead, it utilizes snap-fit ​​fixing, magnetic fixing, or other methods to ensure that the connection does not loosen during circumferential rotation during locking. Furthermore, the manual grip 102 of this disclosure can be configured as a cube, a symmetrical trapezoid, a cylinder, etc., to ensure that the circumferentially distributed force is uniform during tightening.

[0035] In some embodiments, the manual grip portion 102 is configured as a cylinder, and the diameter of the manual grip portion 102 is greater than or equal to the diameter of the polygonal connector 1031.

[0036] In this embodiment, the cylindrical manual grip portion 102, with a diameter greater than or equal to that of the polygonal connector 1031, provides a more stable grip base to ensure uniform grip force distribution. In terms of force transmission, the larger-than-equal diameter of the manual grip portion 102 allows the operator to achieve the connection with less grip force. Furthermore, the stepped structure formed by the diameter difference facilitates rapid positioning within narrow oral cavity spaces while avoiding interference between instrument components.

[0037] In some embodiments, a plurality of anti-slip grooves 1021 are evenly distributed on the circumferential sidewall of the manual grip portion 102, and the anti-slip grooves 1021 form an arc-shaped groove structure.

[0038] In this embodiment, the evenly distributed anti-slip grooves 1021 form a multi-directional friction texture, significantly increasing the coefficient of friction on the grip surface and effectively preventing instrument slippage during surgery due to hand sweat or blood. The arc-shaped groove structure design avoids dead corners where dirt accumulates, facilitating thorough disinfection and cleaning of instruments post-operatively and reducing the risk of cross-infection. In terms of equipment use, the arc-shaped groove structure can disperse stress concentration, prevent cracks from appearing at the root of the anti-slip grooves, and extend the service life of the instruments.

[0039] In some embodiments, the edge of the polygonal connector 1031 away from the manual grip portion 102 is configured as an arc surface.

[0040] In this embodiment, the end edge of the polygonal connector 1031 is designed as a rounded surface. The rounded edge prevents sharp edges from scratching the soft tissues of the oral cavity, and the rounded transition structure effectively disperses contact stress during operation, avoiding local stress concentration caused by right-angled edges, and significantly improving the fatigue resistance of the polygonal connector 1031. Specifically, the polygonal connector 1031 in various embodiments of this disclosure serves as a key component used in conjunction with the wrench 20. The specific shape of the polygonal connector 1031 can be triangular, square, or hexagonal. The polygonal connector 1031 matches the socket hole 2011 of the socket section 201 to ensure accurate torque transmission. The hexagonal connector is more versatile, while the square connector has better anti-slip properties. This disclosure specifically selects a square connector.

[0041] In some embodiments, a quick-change structure is provided between the lower end of the cylinder 101 and the manual grip 102, and the quick-change structure is configured as a hexagonal magnetic slot or a spring bead positioning component.

[0042] In this embodiment, a quick-change structure design using a hexagonal magnetic slot or a spring bead positioning component can be adopted between the lower end of the cylinder 101 and the manual grip 102. The hexagonal structure provides six evenly distributed contact surfaces, ensuring minimal coaxiality error between the cylinder 101 and the manual grip 102, preventing torque transmission misalignment. The hexagonal magnetic slot contains a built-in neodymium magnet that instantly attracts the cylinder 101, reducing operation time and preventing accidental dislodgement during surgery. The standardized hexagonal interface is compatible with a wide range of implantation system cylinders 101. The spring bead positioning component offers the advantage of dual locking: the spring bead embeds into the groove of the cylinder 101 to form a mechanical interlock, and combined with magnetic adsorption, it can withstand greater torque without loosening. During replacement, the spring bead makes a clicking sound indicating proper installation, reducing the rate of operational errors. Both structures allow for one-handed replacement, significantly shortening surgical time, and the snap-fit ​​method avoids the risk of cross-infection associated with traditional threaded connections. It should be noted that the quick-change structure design of the hexagonal magnetic slot or spring ball positioning component is not shown in the specific drawings, but the scope of protection of the claims disclosed herein can be determined and expanded as much as possible through the above description.

[0043] In some embodiments, a plurality of illumination sources 1022 are circumferentially arranged on the lower end face of the manual grip 102 connected to the cylinder 101, and the plurality of illumination sources 1022 are focused on the end of the cylinder 101. The circumferentially distributed plurality of LED light sources form a ring light band, and the cross-focusing eliminates shadows in the surgical area to achieve multi-angle shadowless illumination, significantly improving the clarity of the field of vision. The focusing design concentrates the light spot on the operating surface at the end of the cylinder 101, avoiding the interference of scattered light with the surrounding area. The power supply can be a micro battery or the like, and the specific circuit layout is a conventional setting of the prior art, which will not be described in detail here.

[0044] In some embodiments, the number of wrenches 20 is two, namely a first wrench 20A and a second wrench 20B, such as... Figure 3 As shown, the gripping and force-applying section 202 of the first wrench 20A is offset to the right relative to the socket section 201 to form an obtuse angle connection with the socket section 201; as Figure 4 The gripping and applying force section 202 of the second wrench 20B shown is deflected to the left relative to the socket section 201 to form an obtuse angle connection with the socket section 201. In actual use, the first wrench 20A and the second wrench 20B are used individually. The obtuse angle α described in this disclosure can be controlled within the range of 145 degrees or greater to 155 degrees or less. In this embodiment, 150 degrees is particularly preferred, as this angle value is the most labor-saving and easy to operate when tightening.

[0045] In this embodiment, a socket wrench set includes two wrenches 20. During actual tightening, one of the two wrenches 20 is selected for operation. Selecting only the selected wrench 20 for tightening allows for a suitable range of motion at the corresponding planting position, facilitating quick and convenient tightening operations and saving effort.

[0046] In some embodiments, the middle and rear ends of the gripping force application section 202 are fitted with a soft grip sleeve 2021 to increase grip friction.

[0047] In this embodiment, compared to the rigid gripping force application section 202, the soft grip sleeve 2021 is softer in texture, which protects the hand from force application and increases the comfort when gripping. At the same time, it can appropriately increase the grip friction and prevent the device from slipping off due to hand sweat or blood during the locking process.

[0048] A second aspect of this disclosure provides an implantation tool kit, including the socket wrench for locking composite abutments provided in the first aspect of this disclosure. Specifically, the implantation tool kit may also include a tray, a cavity depth measuring device, a fixing clamp, a positioning drill, a side-cutting drill, a twist drill, a tapered drill, a cortical bone drill, a screwdriver, etc.
