Description

Technical Field

[0001] This invention relates to the field of dental medical equipment technology, and in particular to a drill bit handle for anchoring titanium screws. Background Technology

[0002] In dental implant and orthodontic anchorage surgery, dentists use specialized drills to implant anchorage titanium screws through puncture holes in the jawbone. Currently, clinically commonly used drill handles are mainly classified into three types based on their drive mechanism: manual, electric, and a combination of manual and electric. Regardless of the type, all drills require an internal locking mechanism to lock and fix the drill rod.

[0003] The locking structures of existing drill bit handles are generally quite complex, often employing methods such as threaded tightening or multi-stage snap-locking. While these structures can achieve locking, they often require multiple steps, making drill bit assembly and disassembly difficult. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a drill bit handle for supporting titanium nails, which facilitates the assembly and disassembly of drill bits.

[0005] The objective of this invention is achieved by the following technical solution: a drill bit handle for supporting titanium nails, comprising: an installation tube and a clamping assembly;

[0006] The mounting tube has a first receiving cavity that extends through the end of the mounting tube to the external environment; the mounting tube is provided with a drill bit positioning part located in the first receiving cavity, which is used to support the drill bit; the inner wall of the mounting tube is provided with a ventilation channel that extends along the axial direction of the mounting tube.

[0007] The clamping assembly includes a motor, an impeller, and a clamping airbag; the motor is mounted on the mounting tube and supported by the mounting tube; the impeller is sleeved on the drive shaft of the motor and rotates with the drive shaft, and the outer edge of the impeller is connected to the air inlet of the ventilation channel; the clamping airbag is installed in the first accommodating cavity, and the air inlet of the clamping airbag is connected to the air outlet of the ventilation channel, and the clamping airbag is used to clamp or release the drill bit.

[0008] Furthermore, the drill bit handle for supporting titanium nails also includes a sleeve and a limiting slider; the sleeve is sleeved around the drive shaft of the motor and rotates with the motor, and the sleeve is located within the enclosing space of the drill bit positioning part; the sleeve has a second accommodating cavity, and the second accommodating cavity and the enclosing space of the drill bit positioning part are sequentially connected along the axial direction of the mounting tube to jointly form a switching space; the limiting slider is disposed in the switching space, and one end of the limiting slider is connected to the drill bit, so that when the drill bit is pulled by hand, the limiting slider can be driven to rotate or move up and down in the switching space, so that the limiting slider is supported by the drill bit positioning part or the sleeve.

[0009] Furthermore, the sleeve is provided with a first limiting protrusion, which extends from the inner wall of the sleeve toward the axis of the sleeve; the two ends of the limiting slider are respectively provided with a second limiting protrusion and a third limiting protrusion; the second limiting protrusion can abut against the first limiting protrusion so that the limiting slider is supported by the drill bit positioning part; the third limiting protrusion can abut against the first limiting protrusion so that the limiting slider is supported by the sleeve.

[0010] Furthermore, the first limiting protrusion is provided in multiples, and the multiple first limiting protrusions are distributed at intervals around the axis of the sleeve; the second limiting protrusion and the third limiting protrusion are both provided in multiples, and the multiple second limiting protrusions and the multiple third limiting protrusions are respectively distributed at intervals around the axis of the limiting slider.

[0011] Furthermore, one of the sleeve and the limiting slider is provided with an eccentric hole, and the other is provided with an eccentric post, the eccentric post cooperating with the eccentric hole.

[0012] Furthermore, there are multiple eccentric holes, which are distributed at intervals around the axis of the mounting tube; there are multiple eccentric pillars, which are distributed at intervals around the axis of the mounting tube; and one of the eccentric pillars mates with one of the eccentric holes.

[0013] Furthermore, the limiting slider is provided with a magnetic attraction part, which magnetically engages with the drill bit.

[0014] Furthermore, a drill bit handle for supporting titanium nails also includes a collar, which is sleeved on the outside of the clamping airbag and rotatably engages with the inner wall of the mounting tube.

[0015] Furthermore, the collar is linked to the impeller to rotate with the impeller.

[0016] Furthermore, the clamping airbag has a fiber woven mesh structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The mounting tube has a ventilation channel on its inner wall, extending axially along the mounting tube. Preferably, the inlet and outlet of the ventilation channel are annular grooves, and the ventilation channel has multiple ventilation branches, each with its two ends connected to the inlet and outlet respectively. The ventilation channel establishes a path for airflow conduction, which is fundamental for the clamping assembly to hold the drill bit. It should be noted that the ventilation channel is bidirectional and can be used as an exhaust pipe when the clamping assembly is not in operation.

[0019] 2. The clamping airbag is installed within the first accommodating cavity, with its vent connected to the outlet of the ventilation channel. The clamping airbag is used to grip or release the drill bit. The clamping airbag is annular, with a central clearance hole for the drill bit to pass through. Preferably, the clamping airbag is installed below the impeller, closer to the end of the mounting tube. Airflow exits from the impeller's axial side, passes the outer edge of the impeller, enters the ventilation channel through the inlet, and finally exits through the outlet of the ventilation channel, entering the air chamber of the clamping airbag through its vent. Upon influx of gas, the clamping airbag expands radially, gripping the drill bit at its center, restricting its axial movement, and locking it to the mounting tube. Compared to complex locking structures, this design is simple and easy to manufacture and assemble.

[0020] 3. This design eliminates the need for threaded connections or multi-stage snap-fit ​​mechanisms to lock the drill bit. During installation, insert the drill bit into the first receiving cavity from the end of the mounting tube until it is supported by the drill bit positioning part. Then, turn on the motor, and the impeller rotates to inflate the clamping airbag, causing the clamping airbag to expand radially and clamp the drill bit. After turning off the motor, the airbag deflates and releases the drill bit, which can be directly removed from the mounting tube under gravity, making disassembly and assembly very convenient.

[0021] 4. As long as the motor keeps running, the impeller can continuously supply airflow to the clamping airbag, so that the clamping airbag can continuously clamp the drill bit even when the air inlet of the clamping airbag and the air outlet of the air supply channel do not need to be strictly sealed.

[0030] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a drill bit handle for supporting titanium nails, comprising: a mounting tube 1 and a clamping assembly 2;

[0031] The mounting tube 1 has a first receiving cavity 11, which extends through the end of the mounting tube 1 to the external environment; the mounting tube 1 is provided with a drill bit positioning part 12, which is located inside the first receiving cavity 11 and is used to support the drill bit; the inner wall of the mounting tube 1 is provided with a ventilation channel 13, which extends along the axial direction of the mounting tube 1;

[0032] The mounting tube 1 serves as the gripping part of the drill bit handle. To facilitate hand gripping, the mounting tube 1 can be machined to conform to the curvature of the human hand, and anti-slip textures or a rubber sleeve can be machined on its outer wall for stable gripping by the doctor over extended periods. For ease of installation of internal components, the mounting tube 1 can be machined into two interlocking arc-shaped tubes. The mounting tube 1 has a first receiving cavity 11, which accommodates other components. The first receiving cavity 11 can be machined into an irregular shape to accommodate components with different appearances. The first receiving cavity 11 extends through the end of the mounting tube 1 to connect with the external environment, allowing the drill bit to be smoothly inserted into the first receiving cavity 11 from the end of the mounting tube 1. The drill bit positioning part 12 is located within the first accommodating cavity 11. The drill bit positioning part 12 supports the drill bit and is part of the mounting tube 1. In one embodiment, the drill bit can be inserted into the positioning hole of the drill bit positioning part 12. To prevent the drill bit from falling out of the first accommodating cavity 11 under gravity, the end of the mounting tube 1 needs to be placed upwards. The main function of the drill bit positioning part 12 is to initially position the drill bit and prevent it from swinging within the first accommodating cavity 11, rather than directly locking the drill bit. A ventilation channel 13 is provided on the inner wall of the mounting tube 1, extending axially along the mounting tube 1. Preferably, the inlet and outlet of the ventilation channel 13 are annular grooves, and the ventilation channel 13 has multiple ventilation branches, with each branch connected to the inlet and outlet respectively. The ventilation channel 13 establishes a path for airflow conduction, which is the basis for the clamping assembly 2 to clamp the drill bit.

[0033] The clamping assembly 2 includes a motor 21, an impeller 22, and a clamping airbag 23. The motor 21 is mounted on the mounting tube 1 and supported by the mounting tube 1. The impeller 22 is sleeved on the drive shaft of the motor 21 and rotates with the drive shaft. The outer edge of the impeller 22 is connected to the air inlet of the ventilation channel 13. The clamping airbag 23 is installed in the first accommodating cavity 11. The air outlet of the clamping airbag 23 is connected to the air outlet of the ventilation channel 13. The clamping airbag 23 is used to clamp or release the drill bit.

[0034] As a preferred installation method, the motor 21 is installed in the dedicated motor installation space of the first accommodating cavity 11, or the motor 21 can be installed on the outer wall of the mounting tube 1. The impeller 22 is sleeved around the drive shaft of the motor 21 and rotates with the drive shaft. The outer edge of the impeller 22 connects to the air inlet of the ventilation channel 13. It can be understood that after the motor 21 starts, the impeller 22 rotates together with the drive shaft of the motor 21, and the impeller 22 throws airflow from the axial side of the impeller 22 to the outer edge side of the impeller 22. The airflow passes through the outer edge side of the impeller 22 and enters the ventilation channel 13 through the air inlet. An external air pump can be used to circumvent airflow into the first accommodating cavity 11 to ensure that the impeller 22 can continuously supply airflow to the air inlet of the ventilation channel 13. As a preferred design, the outer edge of the impeller 22 is rotatably fitted with the air inlet (e.g., an annular groove) of the ventilation channel 13 so that the impeller 22 can circumferentially supply airflow to the ventilation channel 13. The clamping airbag 23 is installed within the first accommodating cavity 11, and its vent is connected to the outlet of the ventilation channel 13. The clamping airbag 23 is used to grip or release the drill bit. The clamping airbag 23 is an annular airbag with a central clearance hole for the drill bit to pass through. Preferably, the clamping airbag 23 is installed below the impeller 22, closer to the end of the mounting tube 1. Airflow exits from the axial side of the impeller 22, passes through the outer edge of the impeller 22, enters the ventilation channel 13 through the inlet, and finally exits from the outlet of the ventilation channel 13 through the vent of the clamping airbag 23 into its air chamber. After being filled with gas, the clamping airbag 23 expands radially, gripping the drill bit at its center, restricting its axial movement, and locking it to the mounting tube 1. Compared to complex locking structures, this design is simple and easy to manufacture and assemble. It is understandable that this design does not require locking the drill bit through threaded engagement or multi-stage snap-fit. It should be noted that, as a preferred solution, the ventilation channel 13 is a bidirectional channel, which can be used as an exhaust pipe when the clamping assembly 2 is not in operation. If the ventilation channel 13 is a unidirectional channel (e.g., a Venturi tube type channel, or a ventilation channel 13 covered with a microporous membrane), airflow is only allowed from the inlet to the outlet of the ventilation channel 13. This means that reverse exhaust is inefficient, requiring an additional unidirectional exhaust pipe to connect the unidirectional intake channel, clamping airbag 23, and unidirectional exhaust channel sequentially. Furthermore, the flow cross-sectional area of ​​the unidirectional exhaust channel must be smaller than that of the unidirectional intake channel. It is understandable that while a unidirectional ventilation channel 13 can still achieve normal exhaust from the clamping assembly 2, it requires an additional exhaust pipe, which not only complicates the internal structure of the first accommodating cavity 11 but also increases costs.

[0035] The working principle of this invention is as follows: During installation, the drill bit is inserted into the first receiving cavity 11 from the end of the mounting tube 1 until it is supported by the drill bit positioning part 12. Then, the motor 21 is turned on, and the impeller 22 rotates to inflate the clamping airbag 23, causing the clamping airbag 23 to expand radially and clamp the drill bit. After the motor 21 is turned off, the airbag deflates and releases the drill bit, which can be directly removed from the mounting tube 1 under the action of gravity, making disassembly and assembly very convenient. In addition, as long as the motor 21 is working, the impeller 22 can continuously supply airflow to the clamping airbag 23, so that the clamping airbag 23 can continuously clamp the drill bit even when the air inlet of the clamping airbag 23 and the air outlet of the air supply channel do not need to be strictly sealed.

[0036] like Figures 1 to 3As shown, preferably, the drill bit handle for supporting titanium nails further includes a sleeve 3 and a limiting slider 4; the sleeve 3 is sleeved on the drive shaft of the motor 21 and rotates with the motor 21, the sleeve 3 is located within the enclosing space of the drill bit positioning part 12; the sleeve 3 has a second accommodating cavity 31, the second accommodating cavity 31 and the enclosing space of the drill bit positioning part 12 are sequentially connected along the axial direction of the mounting tube 1 to jointly form a switching space 5; the limiting slider 4 is disposed in the switching space 5, one end of the limiting slider 4 is connected to the drill bit, so that when the drill bit is pulled by hand, the limiting slider 4 can be driven to rotate or move up and down in the switching space 5, so that the limiting slider 4 is supported by the drill bit positioning part 12 or the sleeve 3. As a preferred design, the sleeve 3 is threaded onto the drive shaft of the motor 21, rotating along with it when the motor 21 is driven. The impeller 22 can be sleeved on the sleeve 3 or spaced apart from the sleeve 3 along the axial direction of the mounting tube 1. At least a portion of the sleeve 3 falls into the enclosing space of the drill bit positioning part 12, thus creating a basis for the formation of the switching space 5. A second receiving cavity 31 is provided at the bottom of the sleeve 3, which is connected to the external environment. After the sleeve 3 is sleeved onto the drive shaft of the motor 21, the second receiving cavity 31 is connected to part of the enclosing space of the drill bit positioning part 12, thus forming the switching space 5. Since the sleeve 3 rotates while the drill bit positioning part 12 remains stationary when the motor 21 is working, this creates a basis for switching between manual and electric modes of the drill bit. A limiting slider 4 is installed in this limiting space. As a preferred design, the limiting slider 4 has a limiting hole at its bottom, into which the drill bit is inserted. When the drill bit head is rotated or pushed by hand, the limiting slider 4 can move up and down or rotate within the switching space 5. This allows the limiting slider 4 to be supported by the sleeve 3 or the drill bit positioning part 12. When the limiting slider 4 is supported by the drill bit positioning part 12, the drill bit handle is in manual operation mode; when the limiting slider 4 is supported by the sleeve 3, the drill bit handle is in electric operation mode. In other words, the drill bit handle has both manual and electric operation functions, eliminating the need for frequent handle switching during surgery and facilitating smoother procedures. It should be noted that the limiting slider 4 can rotate within the switching space 5 primarily to avoid the limiting structure of the limiting sleeve 3.

[0037] like Figures 2 to 4As shown, preferably, the sleeve 3 is provided with a first limiting protrusion 32, which extends from the inner wall of the sleeve 3 toward the axis of the sleeve 3; the two ends of the limiting slider 4 are respectively provided with a second limiting protrusion 41 and a third limiting protrusion 42; the second limiting protrusion 41 can abut against the first limiting protrusion 32 so that the limiting slider 4 is supported by the drill bit positioning part 12; the third limiting protrusion 42 can abut against the first limiting protrusion 32 so that the limiting slider 4 is supported by the sleeve 3. For ease of explanation, the second limiting protrusion 41 is located at the end of the limiting slider 4 furthest from the drill bit (near the top), and the third limiting protrusion 42 is located at the end of the limiting slider 4 closest to the drill bit (near the bottom). When the limiting slider 4 is supported by the drill bit positioning part 12 (i.e., in manual mode), the bottom surface of the first limiting protrusion 32 abuts against the top surface of the second limiting protrusion 41, thereby limiting the limiting slider 4 from moving upwards during vibration or when tightening the screw, ensuring it is always stably supported by the drill bit positioning part 12. When the limiting slider 4 is supported by the sleeve 3 (i.e., in electric mode), the bottom surface of the third limiting protrusion 42 abuts against the top surface of the first limiting protrusion 32, thereby preventing the limiting slider 4 from falling under gravity, ensuring the limiting slider 4 is always supported by the sleeve 3. Therefore, through the coordinated operation of the first limiting protrusion 32, the second limiting protrusion 41, and the third limiting protrusion 42, the drill bit handle can be guaranteed to work normally in both manual and electric modes.

[0038] The switching method of the limiting module is as follows: If the limiting module is initially supported by the drill bit positioning part 12, then the second limiting protrusion 41 cooperates with the first limiting protrusion 32. The drill bit needs to be manually rotated first to prevent the second limiting protrusion 41 from interfering with the first limiting protrusion 32. Then, the drill bit is pushed, which smoothly moves the limiting slider 4 into the second receiving cavity 31. Then, the drill bit is rotated again so that the bottom surface of the third limiting protrusion 42 abuts against the top surface of the first limiting protrusion 32. At this time, the limiting slider 4 can be stably supported by the sleeve 3, completing the switch from manual mode to electric mode. Conversely, the same principle applies to the switch from electric mode to manual mode.

[0039] like Figures 2 to 4As shown, preferably, multiple first limiting protrusions 32 are provided, and the multiple first limiting protrusions 32 are distributed at intervals around the axis of the sleeve 3; multiple second limiting protrusions 41 and multiple third limiting protrusions 42 are provided, and the multiple second limiting protrusions 41 and multiple third limiting protrusions 42 are distributed at intervals around the axis of the limiting slider 4. It can be understood that, as a preferred design, the first limiting protrusions 32 are evenly distributed at intervals around the axis of the sleeve 3; the multiple second limiting protrusions 41 and multiple third limiting protrusions 42 are evenly distributed at intervals around the axis of the limiting slider 4; the second limiting protrusions 41 and the third limiting protrusions 42 correspond one-to-one in the vertical direction, so that the lifting and lowering movement of the limiting slider 4 can be smoothly completed with only one rotation action. The purpose of setting multiple first limiting protrusions 32, second limiting protrusions 41 and third limiting protrusions 42 is to enable the limiting slider 4 to be restricted in the circumferential direction, so that the limiting slider 4 is more stably supported by the drill bit positioning part 12 or the sleeve 3, thereby ensuring the working stability of the drill bit handle in manual or electric mode.

[0040] like Figures 2 to 4 As shown, preferably, one of the sleeve 3 and the limiting slider 4 is provided with an eccentric hole 6, and the other is provided with an eccentric post 7, the eccentric post 7 cooperating with the eccentric hole 6. When the limiting slider 4 switches to electric mode, the eccentric hole 6 and the eccentric post 7 cooperate to prevent slippage between the limiting slider 4 and the sleeve 3, ensuring that the limiting slider 4 can rotate with the sleeve 3, thereby improving the working stability in electric mode.

[0041] like Figures 2 to 4 As shown, preferably, there are multiple eccentric holes 6, which are distributed at intervals around the axis of the mounting tube 1; there are multiple eccentric pillars 7, which are distributed at intervals around the axis of the mounting tube 1; one of the eccentric pillars 7 mates with one of the eccentric holes 6. When the limiting slider 4 switches to electric mode, the eccentric pillars 7 are inserted into the eccentric holes 6 one by one, thereby preventing slippage between the limiting slider 4 and the sleeve 3, ensuring that the limiting slider 4 can rotate with the sleeve 3, and thus improving the working stability in electric mode.

[0042] like Figures 2 to 4 As shown, preferably, the limiting slider 4 is provided with a magnetic suction part 43, which magnetically engages with the drill bit. The magnetic suction part 43 can be the magnetic end face of the limiting hole (e.g., a neodymium iron boron permanent magnet surface). When the drill bit is inserted into the limiting hole, the end face of the drill bit and the magnetic end face magnetically engage, so that even when the end of the mounting tube 1 is placed downwards, the drill bit will not detach from the mounting tube 1 under the action of gravity, thus improving the assembly stability of the drill bit.

[0043] like Figures 2 to 3As shown, preferably, a drill bit handle for supporting titanium nails further includes a collar 8, which is sleeved on the clamping airbag 23 and rotatably engages with the inner wall of the mounting tube 1. In electric mode, the clamping airbag 23 rotates along with the drill bit because it clamps the drill bit. The collar 8, sandwiched between the clamping airbag 23 and the inner wall of the mounting tube 1, serves to buffer and protect the clamping airbag 23, preventing it from being scratched by rotational friction and ensuring the stability of the clamping state. Furthermore, the collar 8 is a wear part and is easy to replace.

[0044] like Figures 2 to 3 As shown, preferably, the collar 8 is linked to the impeller 22 to rotate with the impeller 22. It can be understood that before the clamping airbag 23 clamps the drill bit, the collar 8 can inflate the clamping airbag 23 while it is rotating. Once the clamping airbag 23 clamps the drill bit, even if the limiting slider 4 is supported by the drill bit positioning part 12 (which should be in manual mode), the clamping airbag 23 can still drive the drill bit to rotate. That is, the drill bit is in a long-term electric mode, which is especially suitable for surgical scenarios that require a constant electric mode. To switch to manual mode, simply turn off the motor 21. It should be noted that the clamping airbag 23 needs to have a sealing structure in manual mode to prevent the clamping airbag 23 from leaking air and causing the clamping state to fail when the impeller 22 stops supplying airflow to the clamping airbag 23.

[0045] like Figures 2 to 3 As shown, preferably, the clamping airbag 23 has a fiber woven mesh structure. The fiber woven structure can directionally constrain the deformation of the airbag wall, causing it to expand mainly radially during inflation, thereby more quickly and centrally converting the inflation pressure into a clamping force on the drill bit's circumference. This design can minimize the axial extension of the airbag, shorten the clamping time, and improve clamping efficiency.
