Description

Technical Field

[0001] The present application relates to the field of oral implant tools, and in particular to a universal torque handle for dental implant surgery and a method for using the handle. Background Art

[0002] In the process of oral implant dentures, a variety of drills are required to install and fix the implants and abutments. For example, the implant needs to be tightened with a special screwdriver, and the abutment also needs to use a corresponding screwdriver to tighten the corresponding screws to ensure a tight connection between the abutment and the implant. An implant drill is also required to drill holes. This requires the preparation of multiple specifications of screwdrivers, dental drills and other drills for oral implants. In addition, the drills used in different hospitals are produced by different manufacturers, which makes it difficult for different handles to be used with different drills.

[0003] At the same time, a standard I-shaped structure is set at the end of each drill needle, and one side of the end of the drill needle I-shaped structure is an arc surface and the other side is a plane, so that the drill needle can be rotated in the handle to obtain axial fixation, for example, a minimally invasive dental implant set drill bit with announcement number CN204839798U. Since the drill needle generally has a small diameter, it is inevitable that it will break during use, which makes it difficult to remove the traditional drill needle from the handle after it breaks, making the handle unusable later.

[0004] In order to facilitate operation, the handle of each drill needs to be larger in size and takes up more space. In order to save placement space, some implant drills and handles are designed to be split. For example, an ASC angle screwdriver with announcement number CN217572683U has a handle and a head at both ends of the connecting rod. The head is fixed with a protruding connecting block, which is plugged into the connecting rod. A strong magnet is set on the connecting rod to fix the connecting block by magnetic attraction.

[0005] With respect to the above-mentioned related technologies, during the process of the connecting block being inserted into the connecting rod, since the connecting block can move in the radial direction of the drill needle relative to the connecting rod, it is difficult for the center lines of the cutter head and the connecting rod, that is, the drill needle and the handle, to be consistent. As a result, during the process of turning the handle, the drill needle does not rotate around its own center line, and after the strong magnet block is magnetically attracted to the connecting block, it will be difficult to achieve fine adjustments to the radial position between the drill needle and the handle, affecting the normal use of the drill needle. Summary of the invention

[0006] In order to meet the requirement of separate design of drill and handle while not easily affecting the normal use of the drill, the present application provides a universal torque handle for dental implant surgery and a method for using the handle.

[0007] The present application provides a universal torque handle for dental implant surgery that adopts the following technical solution.

[0008] A universal torque handle for dental implant surgery includes a handle body for holding, a plurality of elastic clips connected to the working end of the handle body, and a sleeve sleeved on all the clips. There is a spacing between two adjacent clips, and a cavity is formed between all the clips for one I-shaped end of a drill to extend into. The sleeve can reduce the space of the cavity so that the position of the drill is fixed.

[0009] By adopting the above technical solution, all the clips clamp the drill needle so that the clamped drill needle is difficult to rotate or move axially, and the axis of the drill needle and the center line of the handle body can be well consistent and not easily deviated. In addition, the present application can also be well adapted to drill needles of different specifications produced by different manufacturers, thereby improving the applicability to drill needles of various specifications. In addition, even if the drill needle breaks during use, the drill needle can be dropped from the handle body by simply moving all the clips away from the drill needle, so that the broken drill needle can be removed from the handle.

[0010] Optionally, the sleeve can be rotated so that the sleeve itself moves relative to the clip to force the space of the cavity to change.

[0011] By adopting the above technical solution, the drill bit can be clamped by the clamping piece by rotating the sleeve.

[0012] Optionally, the handle body is formed with a threaded section for threaded connection of the sleeve.

[0013] By adopting the above technical solution, the sleeve can be moved along the center line direction of the handle body by rotating the sleeve.

[0014] Optionally, the sleeve is rotatably connected to the handle body, the handle body includes a rod and an axial shift column slidably connected to the rod along the axis of rotation of the sleeve, one end of all the clips is connected to the axial shift column, and the sleeve is threadedly connected to the axial shift column so that the axial shift column only moves along the axis of the sleeve.

[0015] By adopting the above technical solution, when the sleeve is rotated, the sleeve will not move along its own axial direction, so that the sleeve is kept in a fixed axial position, forcing the clamp to clamp the drill bit.

[0016] Optionally, the handle body includes a rod portion to which the clips are fixedly connected and a handle connected to the rod portion for rotation around a center line surrounded by all the clips, the handle being used for gripping to obtain the rotational torque of the drill bit, the rod portion being fixedly connected to a slave end toothed disc, the slave end toothed disc being meshed with a main end toothed disc connected to the handle for sliding along the axis of rotation of the handle, an elastic member abutting against the side of the main end toothed disc facing away from the slave end toothed disc, the elastic member forcing the main end toothed disc to move toward the slave end toothed disc, so that the rod portion and the drill bit can remain stationary relative to the handle when the rotational torque provided by the handle exceeds a preset value.

[0017] By adopting the above technical solution, when the torque value of the drill needle is too large, the elastic part is compressed, so that the main end gear disc will no longer drive the slave end gear disc to rotate when it rotates, and the drill needle will not continue to rotate along with the rotation of the grip when the torque value is too large, so as to limit the maximum rotational torque of the drill needle and reduce the possibility of damage to the drill needle or the physiological structure of the surgical area.

[0018] Optionally, the handle is rotatably connected to one end away from the rod, and the adjusting knob is coaxially fixedly connected to an adjusting screw. The adjusting screw is threadedly connected to a pressure regulating block that only moves along the rotation axis of the handle. The pressure regulating block abuts against the end of the elastic member away from the main end gear disk, so that the maximum rotational torque that the rod and the drill bit can rotate synchronously with the handle can be adjusted accordingly.

[0019] By adopting the above technical solution, the maximum rotational torque at which the drill bit can rotate is adjusted and changed to better meet the needs of different occasions.

[0020] Optionally, the pressure regulating block is fixedly connected with a push rod that can abut against the main end toothed disc, so that when the push rod abuts against the main end toothed disc, the rod part and the drill needle can always rotate along with the handle.

[0021] By adopting the above technical solution, when the abutment rod abuts against the main end gear disc, the maximum rotational torque of the drill bit is not limited, so as to be suitable for some occasions that require the drill bit to rotate with a larger torque value.

[0022] Optionally, the handle body is provided with a rod cavity at one end of the clip for one end of the drill needle to enter, and a flat veneer block that can fit the I-shaped structure of the end of the drill needle is fixedly connected in the rod cavity to reduce the possibility of breakage and damage at one end of the I-shaped structure of the drill needle.

[0023] By adopting the above technical solution, when the present application is used in combination with an existing traditional drill bit, since the veneer block can fit the plane of the I-shaped end of the drill bit, the thinner diameter part of the I-shaped end of the drill bit is not easy to break.

[0024] The present application also provides a method for using a handle using the following technical solution.

[0025] A method for using a handle is applied to the above-mentioned universal torque handle for dental implant surgery, and specifically includes the following steps.

[0026] Step 1: Place the drill needle into the cavity and insert it into the rod cavity; Step 2: Rotate the drill needle until the surface of the drill needle fits the veneer block and continue to insert it; Step 3: Rotate the sleeve so that all the clips are in close contact with the drill needle; Step 4: Turn the adjustment knob to the appropriate position and start using the handle.

[0027] By adopting the above technical solution, drill bits of different specifications can be connected and fixed to the handle more conveniently and stably.

[0028] In summary, the present application includes at least the following beneficial effects.

[0029] By rotating the sleeve, the ends of all the clips can clamp the drill bit, so that the clamped drill bit is difficult to rotate or move axially, and the axis of the drill bit and the center line of the handle body can be well consistent and less prone to deviation. In addition, the present application can also better adapt to drill bits of different specifications produced by different manufacturers, thereby improving the applicability to drill bits of various specifications.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application embodiment discloses a universal torque handle for dental implant surgery, referring to Figure 1 , including a handle body 1 for the doctor to hold by hand, a circle of clips 3 are evenly fixedly connected to one end surface of the handle body 1, and the clips 3 are evenly arranged around the center line of the handle body 1. The drill needle needed in the implantation process is placed in the circle of clips 3 and inserted into the handle body 1. There is a sleeve 4 at one end of the clip 3 of the handle body 1, and the sleeve 4 rotates around the center line of all the clips 3 so that all the clips 3 can clamp the drill needle.

[0034] Reference Figure 1The handle body 1 includes a rod 2 and a grip 35. The grip 35 is installed on the same center line as the rod 2 at one end away from the clip 3. A threaded section 41 is formed on the surface of the rod 2 around its own center line. The threaded section 41 is threadedly connected to the inner wall of the sleeve 4 so that the sleeve 4 can move along the center line of the rod 2 during the rotation of the sleeve 4.

[0035] Reference Figure 2 In other implementations of the present embodiment, the sleeve 4 is coaxially rotatably connected to the end face of the rod 2, and the handle body 1 further comprises an axis shifting column 42 coaxially threadedly connected to the inner wall of the sleeve 4, the axis shifting column 42 is inserted along the axis of the rod 2 and slidably connected to the rod 2, and all the clips 3 are fixedly connected to the end face of the rod 2, so that in the process of rotating the sleeve 4, the axis shifting column 42 together with all the clips 3 move along the axis direction of the rod 2, so that the clips 3 can clamp or release the drill needle. At the same time, in order to prevent the axis shifting column 42 from being easily rotated synchronously when the sleeve 4 rotates, thereby affecting the movement of the axis shifting column 42 along the axis direction of the rod 2, the portion of the axis shifting column 42 inserted into the rod 2 can be provided with a non-circular cross section such as an elliptical or rectangular shape, and a protrusion can also be provided at one end of the axis shifting column 42 inserted into the rod 2 or inside the rod 2, so as to achieve stable movement of the axis shifting column 42.

[0036] Reference Figure 2 , the closer the clips 3 are to one end of the rod 2, the thicker they are, so that the connection between the clips 3 and the rod 2 is not easily damaged. In addition, the closer the two clips 3 are to the two ends of the rod 2, the larger the distance between them. The movement of the sleeve 4 in the direction close to the rod 2 can force all the clips 3 to move away from one end of the rod 2, so that when the sleeve 4 is close to the rod 2, the clips 3 can be forced to clamp the drill needle. In addition, the inner diameter of the inner wall of the sleeve 4 can be smaller at a position farther away from the rod 2, so that the movement of the sleeve 4 can more effectively adjust the clamping force of the clips 3 on the drill needle.

[0037] In other implementations of this embodiment, the closer each pair of two clips 3 are to the ends of the rod 2, the smaller the distance between them is. The sleeve 4 moves in a direction away from the rod 2 to force all the clips 3 to move closer to one end away from the rod 2, so that when the sleeve 4 is away from the rod 2, the clips 3 can be forced to clamp the drill needle. In addition, in this embodiment, one end of the clip 3 away from the rod 2 can form a convex block protruding toward one side of the drill needle, so that the end of the clip 3 away from the rod 2 can be better bent to press the drill needle.

[0038] Reference Figure 3A rod cavity 36 is coaxially opened at the center of one end of the rod 2 where the clip 3 is provided, and a veneer block 37 is fixedly connected to the rod cavity 36. After one end of the I-shaped structure of the drill needle is inserted into the rod cavity 36 and the drill needle is rotated to a predetermined angle, the drill needle can move a short distance along the axial direction of the rod 2, so that the plane of one end of the I-shaped structure of the drill needle can fit into the plane of the veneer block 37. On the one hand, the drill needle is limited to rotate arbitrarily after installation is completed, and on the other hand, the smaller diameter part of the I-shaped structure of the traditional drill needle is fit into a larger area with the plane of the veneer block 37, thereby reducing the possibility of breakage at the smaller diameter part of the I-shaped structure of the drill needle.

[0039] Reference Figure 4 The handle 35 is connected to the rod 2 by rotating around its own center line. A slave-end toothed disc 45 is fixedly connected to the rod 2 at one end facing the handle 35 and the same center line. A master-end toothed disc 46 is slidably connected to the handle 35 along its own center line. The master-end toothed disc 46 engages with the slave-end toothed disc 45. An elastic member 47 is installed in the handle 35, which can force the main-end toothed disc 46 to move toward the slave-end toothed disc 45. The elastic member 47 can be a compression spring. The end of the elastic member 47 away from the main-end toothed disc 46 is abutted against a pressure regulating block 49. The pressure regulating block 49 is slidably connected to the inside of the handle 35 along the center line direction of the rod 2. An adjusting knob 48 is rotatably connected to the same center line at the end of the handle 35 away from the rod 2. The adjusting knob 48 is coaxially fixedly connected to an adjusting screw 34 threadedly connected to the pressure regulating block 49, so that the pressure regulating block 49 can be driven to move along the center line direction of the handle 35 during the rotation of the adjusting knob 48, so as to adjust the pressure applied to the main-end toothed disc 46 by the elastic member 47, so that the maximum rotational torque that drives the drill bit and the rod 2 to rotate synchronously with the handle 35 during the use of the drill bit can be adjusted. A guide block 31 is fixedly connected to the periphery of the pressure regulating block 49 , a guide groove 32 is opened inside the handle 35 along its own center line direction, and the guide block 31 is slidably connected to the guide groove 32 so that the pressure regulating block 49 can move stably along with the rotation of the adjusting knob 48 .

[0040] Reference Figure 4 A push rod 33 is fixedly connected to the pressure regulating block 49 on the side facing the elastic member 47. The push rod 33 can abut against the main end toothed disc 46. When the push rod 33 abuts against the main end toothed disc 46, the main end toothed disc 46 is not easy to move along the center line direction of the handle 35. In this way, during the rotation of the handle 35, the maximum rotational torque of the drill needle and the rod part 2 rotating together with the handle 35 is not restricted.

[0041] The implementation principle of a universal torque handle for dental implant surgery in an embodiment of the present application is as follows: insert the drill needle into the center of a circle of clips 3, rotate the drill needle at a certain angle so that the drill needle can be inserted a short distance further, so that the plane of one end of the I-shaped structure of the drill needle can fit into the plane of the veneer block 37, and then rotate the sleeve 4 so that the sleeve 4 can force all the clips 3 away from the end of the rod 2 to get closer to clamp the drill needle, thereby completing the fixation between the drill needle and the handle.

[0042] The embodiment of the present application also discloses a method for using a handle, which specifically includes the following steps.

[0043] Step 1, placing the drill needle into the cavity 43 and inserting it into the rod cavity 36; Step 2, rotating the drill needle until the surface of the drill needle can fit into the veneer block 37 and continue to extend it; Step 3, rotating the sleeve 4 so that all the clips 3 are in close contact with the drill needle; Step 4: After turning the adjustment knob 48 to a suitable position, start using the handle.

[0044] The implementation principle of a method for using a handle in an embodiment of the present application is that drill bits of different specifications can be conveniently and stably connected and fixed to the handle.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
