Description

Technical Field

[0001] The invention relates to a dental medical device, in particular to a machine converter used in dental implant surgery. Background Art

[0002] Currently in the dental implant surgery process, after drilling a hole at the location where the crown is to be installed on the jawbone, a tap is needed to tap the hole. This is equivalent to setting a threaded hole on the jawbone, and the outer surface of the implant is provided with an external thread that matches the threaded hole. Finally, the jawbone can be installed through a threaded connection.

[0003] The existing operation method is to drill and tap the jawbone through a special dental implant machine. A motor is provided in the head of the implant machine, and a drill bit and a tap can be installed on the head. It is very convenient to use the implant machine for drilling operations. However, when tapping after drilling, due to the large size of the head and the small operating space in the oral cavity, it is difficult to determine the position of the tap and grasp the tapping depth. When using the implant machine to tap the hole, the operation is very inconvenient and the tapping efficiency is low. Summary of the invention

[0004] The purpose of the present invention is to provide a machine converter for dental implant surgery, which can facilitate the determination of the position of the tap and the tapping depth during tapping, thereby improving the tapping efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a machine converter for dental implant surgery, comprising an operating rod, a tap is provided at the end of the operating rod perpendicular to the operating rod, the tap is rotatably set on the operating rod, a fixing piece for fixing the tap on the operating rod is provided on the operating rod, an elastic indicator rod is provided on the side of the operating rod along the length direction of the operating rod, one end of the indicator rod is fixed on the end of the operating rod close to the tap, an indicator block is provided on the outer peripheral surface of the operating rod perpendicular to the operating rod and the indicator rod, the end of the indicator rod away from the tap is slidably set in the indicator block, and a torque mark is provided on the indicator block along the length direction of the indicator block.

[0006] By adopting the above technical solution: When in use, the fixing part can fix the tap on the operating rod, and the tap can be driven to rotate by turning the operating rod to tap the hole. Since the volume of the operating rod is much smaller than the volume of the head of the implanter, the position of the tap can be easily determined during tapping; the tap is fixed to the operating rod through the fixing part, which can facilitate the operation of the operating rod to retract and replace different taps during tapping, so as to achieve the tapping of holes of different diameters, thereby improving the adaptability of the converter. When the indicator rod is pulled, the torque applied to the tap during tapping can be known according to the torque mark on the indicator block, so that the tapping depth can be controlled to adapt to the tapping operation of different types of implants.

[0007] Preferably, a mounting hole is provided at the end of the operating rod perpendicular to the length direction of the operating rod, the fixing member comprises a mounting sleeve detachably fixed in the mounting hole, and the taper rod of the tap is clamped and fixed in the mounting sleeve.

[0008] By adopting the above technical solution: when installing the tap, first fix the installation sleeve to the tap, and then fix the installation sleeve to the installation hole. The installation sleeve can be used as an intermediate medium, and the tap and the operating rod can be fixed without changing the structure of the tap, which has strong versatility.

[0009] Preferably, the mounting sleeve includes a fixing hole that cooperates with the conical rod, the end of the conical rod is provided with an annular groove and a positioning surface, the fixing hole is provided with a convex step that fits with the positioning surface after the conical rod is inserted, and a clamp that is clamped into the annular groove, and the clamp is fixed to the mounting sleeve by a spring clip.

[0010] By adopting the above technical solution: when the conical rod is inserted into the fixing hole, the spring drives the chuck to be clamped into the annular groove, the annular groove cooperates with the chuck to limit the axial sliding of the conical rod in the fixing hole, and the positioning surface cooperates with the convex step to limit the axial rotation of the conical rod in the fixing hole, thereby realizing the fixation of the conical rod in the fixing hole.

[0011] Preferably, a plurality of arc grooves are arranged in a circular array around the outer surface of the mounting sleeve, and a positioning block cooperating with the arc groove and an elastic member driving the positioning block to slide toward the mounting sleeve are arranged on the inner wall of the mounting hole for radial sliding movement along the mounting hole.

[0012] By adopting the above technical solution: when the positioning block slides into the arc groove, since the setting direction of the arc groove is along the axial direction of the mounting hole, the positioning block and the arc groove cooperate to limit the rotation of the mounting sleeve in the mounting hole and the sliding of the mounting sleeve in the operating rod, thereby achieving the fixation of the mounting sleeve and the operating rod. When the operating rod needs to be rotated alone, the positioning block can be slid out of the arc groove, and the connection between the operating rod and the mounting sleeve can be released.

[0013] Preferably, the mounting sleeve is provided with an open groove for the clamp to extend into the fixing hole, the spring piece is arranged in an L shape, the spring piece is arranged around the corner of the mounting sleeve and one end is fixed to the end face of the mounting sleeve, and the clamp is fixed to the other end of the spring piece.

[0014] By adopting the above technical solution: after installation, the spring clip can cover a corner of the installation sleeve, one end of the spring clip is fixed on the end face of the installation sleeve, and the other end extends to the opening groove. The structure is reasonably distributed and occupies little space. The spring clip and the installation sleeve are integrated to ensure the connection strength between the spring clip and the installation sleeve.

[0015] Preferably, a stepped hole communicating with the mounting hole is provided in the operating rod along the length direction of the operating rod, a pull rod connected to the positioning block is slidably provided in the stepped hole, the elastic member is a spring, the spring is arranged in the stepped hole and sleeved on the pull rod, an end cap is threadedly connected to the end of the operating rod, one end of the pull rod away from the positioning block passes through the end cap and then extends out of the operating rod, one end of the spring is fixed to the pull rod, and the other end abuts against the end cap.

[0016] By adopting the above technical solution, the sliding of the positioning block can be realized by pulling the operating rod, and the operation is very convenient. During normal use, the positioning block is always located in the arc groove under the drive of the elastic member, so that the mounting sleeve can always remain fixed with the operating rod.

[0017] Preferably, one end of the indicator block is sleeved outside the operating rod and has an interference fit with the operating rod, and a through groove for the indicator rod to slide is provided in the indicator block along the length direction of the indicator block.

[0018] By adopting the above technical solution: during installation, the indicating block can be adjusted to a suitable position and then tightly sleeved onto the outside of the operating rod. The installation of the indicating block is very convenient, and the through groove can limit the indicating rod to realize the sliding of the indicating rod and the indicating block.

[0019] Preferably, the end of the operating rod protrudes outward to form a convex block, the convex block is provided with a countersunk hole for the indicator rod to be inserted, and the convex block is provided with a pin rod which is perpendicular to the countersunk hole and has an interference fit to fix the indicator rod in the countersunk hole.

[0020] By adopting the above technical solution: when the indicator rod is inserted into the protrusion, the pin rod can fix the indicator rod and fix the indicator rod in the protrusion. The pin rod is detachable, so when replacing the indicator rod, you only need to remove the pin rod, which is very convenient for maintenance.

[0021] Preferably, a conical rod head is provided at one end of the indicating rod away from the mounting hole.

[0022] By adopting the above technical solution: Since the diameter of the indicator rod is small, in order to avoid the end of the indicator rod from piercing the operator, a conical head is provided at the end of the indicator rod away from the mounting hole.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. Since the operating lever takes up little space, it is highly maneuverable;

[0025] 2. The tapping torque can be controlled at any time during tapping, which is very practical;

[0026] 3. Since the tap is fixed on the operating rod through a mounting sleeve, different types of taps can be replaced, which has strong versatility. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0035] A mechanical converter for dental implant surgery, referring to Figure 1 , including an operating rod 1, the end of which is provided with a fixing piece for fixing a tap 2 perpendicular to the operating rod 1. When in use, the tap 2 can be driven to rotate by rotating the operating rod 1 to achieve tapping operation. Since the volume of the operating rod 1 is much smaller than the volume of the head of the planter, the position of the tap 2 can be easily determined during tapping; the tap 2 is fixed to the operating rod 1 by a fixing piece, and different taps 2 can be replaced to achieve tapping of holes of different diameters, thereby improving the adaptability of the converter. Since the diameter of the indicator rod 3 is relatively small, in order to prevent the end of the indicator rod 3 from stabbing the operator, a conical head 31 is provided at the end of the indicator rod 3 away from the mounting hole 12.

[0036] Reference Figure 1In order to facilitate the control of the tapping process, an elastic indicating rod 3 is provided along the side of the operating rod 1 along the length direction of the operating rod 1. In a normal state, the indicating rod 3 is parallel to the operating rod 1. The elastic indicating rod 3 is made of an elastic metal rod. One end of the indicating rod 3 is fixed on the end of the operating rod 1 close to the tap 2, and the other end is slidably arranged in the indicating block 4. One end of the indicating block 4 is fixed on the outer circumferential surface of the operating rod 1. The indicating block 4 is arranged perpendicular to the operating rod 1 and the indicating rod 3. The indicating block 4 and the indicating rod 3 are located in the same plane. A through groove 41 is provided on the indicating block 4 to match the indicating rod 3. The thickness of the through groove 41 is equal to the diameter of the indicating rod 3. The through groove 41 is arranged along the length direction of the indicating block 4. The through direction of the through groove 41 is horizontal. By setting the through groove 41, the end of the indicating rod 3 away from the tap 2 is slidably arranged in the indicating rod 3. The sliding plane of the operating rod 1 is perpendicular to the tap 2. A torque mark 42 is provided on the indicating block 4 along the length direction of the indicating block 4. When the indicator rod 3 is pulled, the torque applied to the tap 2 during tapping can be known according to the torque mark 42 on the indicator block 4, so that the tapping depth can be controlled and the tapping operation of different types of implants can be adapted.

[0037] Reference Figure 1 In order to facilitate the installation of the indicator block 4, one end of the indicator block 4 is sleeved on the end of the operating rod 1 away from the tap 2, and the indicator block 4 and the operating tube are interference fit. When installing, the indicator block 4 is adjusted to a good position and then tightly sleeved on the outside of the operating rod 1.

[0038] Reference Figure 2 as well as Figure 3 A mounting hole 12 is provided at one end of the operating rod 1 for mounting the tap 2. The mounting hole 12 is arranged perpendicular to the length direction of the operating rod 1. In order to reduce the diameter of the operating rod 1 while ensuring the diameter of the mounting hole 12, a protrusion 11 is formed at both ends of the mounting hole 12 and extends outward. The protrusion 11 can increase the width of the end of the operating rod 1 and facilitate the drilling of the mounting hole 12. In addition, a countersunk hole 111 is provided on the protrusion 11 to match the indicator rod 3. The end of the indicator rod 3 is inserted into the protrusion 11. A pin 112 is provided on the protrusion 11 perpendicular to the countersunk hole 111 and is interference-fitted to fix the indicator rod 3 in the countersunk hole 111.

[0039] Reference Figure 4 as well as Figure 5The fixing part includes a mounting sleeve 5 which is detachably fixed in the mounting hole 12. The mounting sleeve 5 is cylindrical in shape. The tapered rod 6 of the tap 2 is fixed in the mounting sleeve 5 by clamping. When the tap 2 is to be replaced, the mounting sleeve 5 is removed from the mounting rod, and then the tapered rod 6 is removed from the mounting sleeve 5. When installing the tap 2, the mounting sleeve 5 is first fixed to the tap 2, and then the mounting sleeve 5 is fixed to the mounting hole 12. The mounting sleeve 5 can be used as an intermediate medium, and the tap 2 and the operating rod 1 can be fixed without changing the structure of the tap 2, and the versatility is strong.

[0040] Reference Figure 4 as well as Figure 5 A fixing hole 53 cooperating with the cone rod 6 is provided on the end surface of the installation sleeve 5. The length of the fixing hole 53 is less than the length of the installation sleeve 5. An annular groove 61 and a positioning surface 62 are provided at one end of the cone rod 6 away from the tap 2. The positioning surface 62 is provided on the outer circumference of the cone rod 6. A convex step 531 that fits with the positioning surface 62 after the cone rod 6 is inserted and a clamping head 541 that is clamped into the annular groove 61 are provided in the fixing hole 53. When the cone rod 6 is inserted into the fixing hole 53, the annular groove 61 cooperates with the clamping head 541 to limit the axial sliding of the cone rod 6 in the fixing hole 53. The positioning surface 62 cooperates with the convex step 531 to limit the axial rotation of the cone rod 6 in the fixing hole 53, thereby achieving the fixing of the cone rod 6 in the fixing hole 53. The clamping head 541 is fixed to the installation sleeve 5 by the spring 54, so that the position of the clamping head 541 can be moved. When the cone rod 6 is to be disassembled, the clamping head 541 is taken out from the annular groove 61 to move the cone rod 6 out of the fixing hole 53.

[0041] Reference Figure 4 as well as Figure 5 An opening groove 55 is provided on the outer peripheral surface of the installation sleeve 5 away from the fixing hole 53 for the clamp head 541 to extend into the fixing hole 53. The spring piece 54 is arranged in an L shape. The corner of the spring piece 54 is arranged corresponding to the corner of the installation sleeve 5. The spring piece 54 is arranged around the corner of the installation sleeve 5. After installation, the spring piece 54 can cover a corner of the installation sleeve 5. One end of the spring piece 54 is fixed on the end surface of the installation sleeve 5, and the other end extends to the opening groove 55. The clamp head 541 is fixed on the other end of the spring piece 54 to realize the connection between the clamp head 541 and the installation sleeve 5. The spring piece 54 is arranged integrally with the installation sleeve 5, so that the connection strength between the spring piece 54 and the installation sleeve 5 can be guaranteed.

[0042] Reference Figure 5 as well as Figure 6In order to facilitate the detachable fixation of the mounting sleeve 5 and the operating rod 1, an arc groove 52 is provided on the outer circumferential surface of the mounting sleeve 5. The cross section of the arc groove 52 in the axial direction is arched. There are a plurality of arc grooves 52, which are arranged in a circular array on the outer circumferential surface of the mounting sleeve 5. A positioning block 7 cooperating with the arc groove 52 is provided on the inner wall of the mounting hole 12 to slide radially along the mounting hole 12. In order to facilitate the control of the positioning block 7, in this embodiment, the sliding direction of the positioning block 7 is along the length direction of the operating rod 1. When the positioning block 7 slides into the arc groove 52, since the setting direction of the arc groove 52 is along the axial direction of the mounting hole 12, the positioning block 7 cooperates with the arc groove 52 to limit the rotation of the mounting sleeve 5 in the mounting hole 12 and the sliding of the mounting sleeve 5 in the operating rod 1, so as to achieve the fixation of the mounting sleeve 5 and the operating rod 1. When the mounting sleeve 5 is to be removed, the positioning block 7 is moved out of the arc groove 52, and the mounting sleeve 5 can be taken out of the mounting hole 12.

[0043] Reference Figure 5 as well as Figure 6 In order to improve the fixing effect between the installation sleeve 5 and the operating rod 1, a circle of flange 51 extends outward from the end of the installation sleeve 5. The flange 51 is set at the end close to the tap 2. The flange 51 fits the side of the protrusion 11 on the operating rod 1, which can play an auxiliary limiting role. At the same time, when tapping, the flange 51 is located below the operating rod 1. When resetting the operating rod 1, the operating rod 1 can only be allowed to retreat. At this time, the positioning block 7 needs to be moved out of the arc groove 52. After the positioning block 7 is moved out of the arc groove 52, the flange 51 can support the operating rod 1 to prevent the operating rod 1 from separating from the installation sleeve 5. In addition, in order not to affect the insertion of the installation sleeve 5 into the installation hole 12, the outer diameter of one end of the installation sleeve 5 with the arc groove 52 matches the inner diameter of the installation hole 12, and the diameter of the other end (the end with the spring 54) is smaller than the inner diameter of the installation hole 12.

[0044] Reference Figure 5 as well as Figure 6In order to ensure that the positioning block 7 can be stably fixed in the arc groove 52, an elastic member driving the positioning block 7 to slide toward the mounting sleeve 5 is provided in the operating rod 1. A recessed groove for the positioning block 7 to slide is provided on the inner wall of the mounting hole 12, and a stepped hole 13 communicating with the recessed groove is provided in the operating rod 1 along the length direction of the operating rod 1, and both ends of the stepped hole 13 extend out of the operating rod 1. The diameter of the end of the stepped hole 13 close to the mounting hole 12 is smaller than the diameter of the end away from the mounting hole 12, and a pull rod 71 is slidably provided in the fine hole of the stepped hole 13, and the end of the pull rod 71 extends into the recessed groove and connects with the positioning block 7. The elastic member is a spring 8, which is arranged in the coarse hole of the stepped hole 13, and the spring 8 is sleeved on the pull rod 71, and a convex ring 711 is provided on the pull rod 71 to abut against one end of the spring 8, and an end cover 9 is threadedly connected to the end of the operating rod 1 away from the mounting hole 12, and the other end of the spring 8 abuts against the end cover 9. Under normal conditions, the spring 8 is always in a compressed state. The end of the pull rod 71 away from the positioning block 7 passes through the end cover 9 and extends out of the operating rod 1 to facilitate manual pulling of the pull rod 71, thereby driving the positioning block 7 to move out of the arc groove 52. Under normal conditions, the elastic force of the spring 8 drives the pull rod 71 and the positioning block 7 to slide toward the arc groove 52, thereby realizing the connection between the positioning block 7 and the arc groove 52, and then realizing the fixation of the mounting sleeve 5 and the mounting hole 12.

[0045] Specific implementation process: when tapping is desired on the hole drilled on the jawbone, the tap 2 is inserted into the fixing hole 53 from the end of the fixing hole 53, the positioning surface 62 of the tap 2 is fitted with the convex step 531 in the fixing hole 53, the clamping head 541 is clamped into the annular groove 61 on the tap 2, and the tap 2 and the mounting sleeve 5 are fixed, and then the mounting sleeve 5 is inserted into the mounting hole 12, and the positioning block 7 is located in the arc groove 52, so that the mounting sleeve 5 and the operating rod 1 are fixed;

[0046] When tapping, the operator manually rotates the operating rod 1 to tap the hole. When the operating rod 1 is to be reset, the pull rod 71 is slid to move the positioning block 7 out of the arc groove 52. At this time, only the operating rod 1 is rotated, and the mounting sleeve 5 and the tap 2 are fixed on the jaw. Repeat the operation until the tapping is completed. When tapping, the indicator rod 3 can be toggled to determine the torque currently applied to the tap 2, the force during tapping, and the tapping depth.

[0047] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
