Description

Technical Field

[0001] The present invention relates to the technical field of artificial dental implantation, and particularly to an auxiliary device for inserting and removing a healing cap. Background Art

[0002] At present, artificial dental implantation is divided into three steps. The first step is to implant an implant into the alveolar bone; the second step is to install a healing cap on the implant. The setting of the healing cap hinders the complete healing of the gum, and the gum will heal to the side wall of the healing cap and form a gum healing surface; after the implant is closely combined with the alveolar bone, the third step is to remove the healing cap and install a prosthetic abutment and a denture, thus completing the whole process of artificial dental implantation.

[0003] Among them, the installation of the healing cap requires the assistance of a screwdriver and a wrench, and the operation is carried out in the narrow space of the oral cavity. When inserting or removing the healing cap, if the operation is not careful, the screwdriver or the healing cap will fall into the deep part of the oral cavity, and it is easy for the dental implant wearer in the lying position to aspirate accidentally and cause danger. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an auxiliary device for inserting and removing a healing cap, which can stably install a healing cap screwdriver on a twisting wrench mechanism, and can limit the bottom of the healing cap during the process of inserting or removing the healing cap, avoiding the healing cap from falling off the end of the healing cap screwdriver, and being able to prevent the healing cap screwdriver or the healing cap from falling into the deep part of the oral cavity and being aspirated by the dental implant wearer, with good safety, and can effectively solve the problems in the background art.

[0005] To achieve the above object, the present invention provides the following technical solution: An auxiliary device for inserting and removing a healing cap, including a twisting wrench mechanism. The twisting wrench mechanism includes a wrench socket, and the left end of the wrench socket is connected with a wrench ring. A limiting through groove is opened at a position corresponding to the middle part of the wrench socket on the wrench ring. A limiting column is inserted in the limiting through groove. A wedge-shaped limiting end is arranged at one end of the limiting column located in the wrench ring. One end of the limiting column located in the wrench socket is fixedly connected with a pushing disk. The right end inner side of the wrench socket is threadedly connected with an external thread sleeve. The outer peripheral side of the right end of the external thread sleeve is connected with an end ring. A reset compression spring is installed in the wrench socket. A healing cap screwdriver is installed in the wrench ring. The device further includes:

[0006] A twisting direction control mechanism, with one end connected to the middle part of the right side of the pushing disk, and the other end of the twisting direction control mechanism connected to the end ring;

[0007] A torque limiting mechanism, installed at the right end of the wrench socket, and the torque limiting mechanism is connected with the twisting direction control mechanism;

[0008] A screwdriver anti-detachment mechanism, installed at one end of the wrench ring close to the wrench socket;

[0009] The healing cap anti - detachment mechanism is installed on the wrench socket ring.

[0010] One side of the wedge - shaped limit end is provided with a clamping plane and the other side is provided with an inclined plane. By means of the end ring, the external thread sleeve can be twisted, so as to facilitate the disassembly and assembly of the external thread sleeve. The external thread sleeve presses against the reset compression spring. The reset compression spring pushes the limit post to move leftward through the push plate, so that the wedge - shaped limit end at the left end of the limit post extends into the wrench socket ring and cooperates with the healing cap screwdriver to install the healing cap screwdriver in the wrench socket ring. The wedge - shaped limit end is clamped with the healing cap screwdriver. Then the healing cap is cooperatively installed on the cross - shaped screwdriver head at the top of the healing cap screwdriver. Then the screw at the top of the healing cap is aligned with the screw hole of the implant in the alveolar bone. By means of the wrench socket, the wrench socket ring is rotated clockwise. The wrench socket ring drives the healing cap screwdriver and the healing cap to rotate clockwise by a certain angle through the clamping plane of the wedge - shaped limit end. The healing cap is screwed into the screw hole of the implant in the alveolar bone. Then, by means of the wrench socket, the wrench socket ring is rotated counterclockwise. Since there is a large frictional force between the implant and the healing cap in the threaded connection, the healing cap and the healing cap screwdriver will not rotate counterclockwise along with the wrench socket ring. At the same time, the inclined plane of the wedge - shaped limit end enables the wedge - shaped limit end to retract into the limit through - groove by overcoming the elastic force of the reset compression spring through the limit post and the push plate. At this time, the healing cap screwdriver in the wrench socket ring does not rotate along with the wrench socket ring. By reciprocally moving the wrench socket, the healing cap screwdriver can be intermittently rotated clockwise, so that the healing cap screwdriver drives the healing cap to be intermittently rotated clockwise, and the placement operation of the healing cap can be completed. By means of the twisting direction control mechanism, the limit post and the wedge - shaped limit end are rotated by 180 degrees, and the positions of the clamping plane and the inclined plane on the wedge - shaped limit end are swapped. At this time, by rotating the wrench socket ring counterclockwise through the wrench socket, the healing cap screwdriver and the healing cap can be driven to rotate counterclockwise, so as to unscrew the healing cap. While by rotating the wrench socket ring clockwise through the wrench socket, the healing cap screwdriver and the healing cap will not rotate. By reciprocally moving the wrench socket, the healing cap can be taken out. The setting of the torque limiting mechanism can limit the torque when the healing cap is placed. If the torque exceeds the limit value for rotating the healing cap, the wedge - shaped limit end will retract into the limit through - groove, so that the clamping plane of the wedge - shaped limit end can no longer act on the healing cap screwdriver, and the clamping action of the clamping plane of the wedge - shaped limit end on the healing cap screwdriver is stopped. At this point, it indicates that the healing cap has been installed in place. The setting of the screwdriver anti - detachment mechanism prevents the healing cap screwdriver from detaching from the wrench socket ring due to the improper angle of using the wrench socket and the wrench socket ring. The healing cap anti - detachment mechanism limits the bottom of the healing cap to prevent the healing cap from detaching from the cross - shaped screwdriver head at the top of the healing cap screwdriver, ensuring that the healing cap screwdriver or the healing cap will not fall in the oral cavity.

[0011] Further, the twisting direction control mechanism includes a control cross shaft. The middle part of the right side of the pushing disc is fixedly connected to the left end of the control cross shaft. The right end of the control cross shaft passes through the center of the external thread sleeve and extends to the outside of the right end of the external thread sleeve. A transverse groove is formed on the outer side of the right end of the control cross shaft. A rotating control sleeve is slidably sleeved on the outer side of the right end of the control cross shaft. A transverse sliding strip slidably connected to the transverse groove is arranged on the inner side of the rotating control sleeve. A control rotating ring is fixedly sleeved on the outer side of the right end of the rotating control sleeve. A transverse control bolt is threadedly connected to the edge of the control rotating ring. Two locking circular holes symmetrical about the center of the end ring are formed on the right end of the end ring. The left end of the control bolt extends into one of the locking circular holes. The control cross shaft can move left and right along with the pushing disc and the limiting post. The rotating control sleeve realizes left and right sliding with the control cross shaft through the transverse sliding strip and the transverse groove, drives the rotating control sleeve to rotate, and thus drives the control cross shaft and the limiting post to rotate. When it is necessary to rotate the limiting post and the wedge-shaped limiting end by 180 degrees to change the direction of the twisting force of the twisting wrench mechanism, loosen the control bolt to make the control bolt leave the current locking circular hole, and then rotate the rotating control sleeve by 180 degrees through the friction protrusion. The rotating control sleeve drives the control cross shaft, the limiting post and the wedge-shaped limiting end to rotate by 180 degrees through the transverse sliding strip and the transverse groove, and then tighten the control bolt. The control bolt extends into another locking circular hole to complete the locking of the rotating control sleeve, and makes the control cross shaft, the limiting post and the wedge-shaped limiting end stable. At this time, the replacement of the positions of the clamping plane and the inclined plane of the wedge-shaped limiting end is completed.

[0012] Further, the torque limiting mechanism includes an arc-shaped long plate. The left ends of two arc-shaped long plates are respectively fixedly connected to the upper and lower sides of the right end of the wrench socket. A pull ring is slidably sleeved on the outer peripheral side of the right end of the control cross shaft, and a limiting end cap is fixedly connected to the right end face of the control cross shaft. The upper and lower sides of the pull ring are respectively movably connected to the left ends of two pull rods through two movable shafts I. The right ends of the two pull rods are respectively movably connected to the left ends of a rotating rod through two movable shafts II. The right end of the rotating rod is rotatably connected to the top of a support column. The bottom of the support column is fixedly connected to the lower arc-shaped long plate. The front and rear sides of the left end of the rotating rod are respectively fixedly connected to the left ends of two mounting brackets. The right ends of the two mounting brackets are fixedly connected to the left end of the end handle. The pull ring is connected to an elastic resistance component, and a torque limiting adjustment component is installed on the elastic resistance component.

[0013] When in use, hold the end handle and turn it clockwise. The end handle can drive the rotating rod to rotate relative to the support column through the mounting bracket. The rotating rod pulls the pull ring to the right through the pull rod. Due to the existence of the limit end cap, the pull ring and the control cross shaft will not separate. When the pulling force of the pull rod on the pull ring is sufficient to overcome the resistance of the elastic resistance component and the reset compression spring, the pull ring pulls the control cross shaft to the right with the help of the limit end cap. The control cross shaft can pull the limit column and the wedge-shaped limit end head to the right, and finally the wedge-shaped limit end head will retract into the limit through groove. At this time, the clamping plane originally acting on the healing cap screwdriver will separate from the healing cap screwdriver, and turning the wrench sleeve clockwise cannot continue to twist the healing cap screwdriver. The torque limiting adjustment component can change the resistance of the elastic resistance component. When the force of turning the end handle is too large, it is impossible to continue to twist the healing cap screwdriver and the healing cap. As a protection measure, it can avoid excessive torque on the healing cap screwdriver and the healing cap from damaging the healing cap or the implant, and can also avoid hurting the alveolar bone of the dental implant patient. It should be noted that the use of the torque limiting mechanism is mainly in the final stage of the healing cap implantation process to limit the maximum torque applied. In the initial stage of the healing cap implantation, generally the wrench sleeve is turned instead of the end handle. This can avoid the friction between the pull ring and the control cross shaft when turning the end handle counterclockwise from affecting the smooth retraction of the limit column and the wedge-shaped limit end head into the limit through groove. And when the wrench sleeve and the wrench ring are turned counterclockwise, the limit column, the wedge-shaped limit end head and the control cross shaft move to the right. At this time, the limit end cap also moves to the right, and the limit end cap has a moving space between the pull ring and the rotating rod.

[0014] Further, the elastic resistance component includes a sliding plate. Two support seats are fixedly connected to the bottom of the upper arc-shaped long plate. Two horizontal sliding columns are respectively fixedly connected between the two support seats. The sliding plate is slidably connected with the two horizontal sliding columns, and the sliding plate is fixedly connected to the pull ring through two connecting rods. The right ends of the two horizontal sliding columns are respectively sleeved with torque limiting compression springs. The support seats are used for installing the horizontal sliding columns. The two torque limiting compression springs provide resistance to the rightward movement of the pull ring with the help of the sliding plate and the connecting rods.

[0015] Furthermore, the torque limiting adjustment assembly includes a limit control plate and a butterfly bolt. The two sliding holes on the limit control plate are respectively slidably connected to the right ends of the two transverse sliding columns. The torque limiting compression spring is located between the slide plate and the limit control plate. A transverse butterfly bolt is threadedly connected to the middle part of the right support seat, and the left end of the butterfly bolt is pressed against the left side of the limit control plate. Twist the butterfly bolt clockwise, the butterfly bolt moves to the left relative to the support seat, thereby pushing the limit control plate to move to the left, and with the help of the limit control plate, the torque limiting compression spring can continue to be compressed, so that the torque limiting compression spring provides greater resistance to the rightward movement of the pull ring, and it is necessary to use greater force to pull the end handle to make the wedge-shaped limit end retract into the limit slot, and it will stop when a larger torque is applied to the healing cap. Conversely, twist the butterfly bolt counterclockwise, the butterfly bolt moves to the right relative to the support seat, and the limit control plate moves to the right along the cross sliding column. The resistance of the compressed torque limiting compression spring to the rightward movement of the pull ring becomes smaller, and the end handle can be pulled with less force to make the wedge-shaped limit end retract into the limit slot, and it will stop when a smaller torque is applied to the healing cap. Therefore, the butterfly bolt can be adjusted according to the torque requirement when the healing cap is installed in place.

[0016] Furthermore, the healing cap screwdriver includes a cylindrical tool holder, a torsion slot, a circular baffle, a boss and a screwdriver rod. The top of the cylindrical tool holder is fixedly connected with a circular baffle. The top center of the circular baffle is fixedly connected to the bottom end of the screwdriver rod through a boss. The outer peripheral side of the cylindrical tool holder is provided with a torsion slot in an annular array. The cylindrical tool holder is installed in the inner circular groove of the wrench ring. The provision of the circular baffle can prevent the cylindrical tool holder from falling downward after being installed in the wrench ring, and can prevent the healing cap screwdriver from detaching from the bottom of the wrench ring. The elastic force of the reset compression spring allows the wedge-shaped limiting end at the end of the limiting column to engage with the torsion slot. The wrench ring is rotated clockwise with the help of the wrench socket. The wrench ring can drive the cylindrical tool holder to rotate through the stable engagement of the clamping plane of the wedge-shaped limiting end with the torsion slot, thereby driving the screwdriver rod to rotate clockwise through the boss. A Pozidriv screwdriver is provided on the top of the screwdriver rod. The head of the Pozidriv screwdriver cooperates with the center of the end of the healing cap, so that the healing cap can be screwed into and installed on the implant in the alveolar bone. With the help of the wrench socket, the wrench ring is turned counterclockwise, and the inclined surface of the wedge-shaped limit end contacts the edge of the torsion slot. Due to the large friction at the connection between the implant and the healing cap, the inclined surface of the wedge-shaped limit end and the edge of the torsion slot slide against each other, allowing the wedge-shaped limit end to overcome the elastic force of the reset compression spring through the limit column and retract into the limit slot. During this process, the cylindrical tool holder does not rotate, and the insertion operation of the healing cap is completed by reciprocating the wrench socket.

[0017] Further, the screwdriver anti - detachment mechanism includes a pressure rod. One end of the wrench socket near the wrench sleeve is installed with a movable seat through a detachable installation component. The movable seat is movably connected to a movable block through a longitudinal rotating shaft. One end of the pressure rod is fixedly connected to the side of the movable block. A semi - circular groove is opened at the other end of the pressure rod. A torsion spring is installed on the longitudinal rotating shaft, and the two ends of the torsion spring are respectively connected to the movable seat and the movable block. The torsion force of the torsion spring makes the left end of the pressure rod move downward, so that the semi - circular groove on the pressure rod cooperates with the bottom end of the screwdriver rod in the healing cap screwdriver. Thus, the left end of the pressure rod presses down the boss in the healing cap screwdriver, preventing the healing cap screwdriver from detaching from the top of the wrench socket, ensuring the stable installation of the healing cap screwdriver in the wrench socket, and avoiding the detachment of the healing cap screwdriver from the wrench socket due to incorrect twisting angle causing the wedge - shaped limit end to disengage from the twisting slot, especially in the scenario where the cross - shaped screwdriver head of the healing cap screwdriver is used downward.

[0018] Further, the detachable installation component includes an installation groove. Two installation grooves are respectively opened on the upper and lower sides of the middle part of one end of the wrench socket near the wrench sleeve. A movable seat is installed in one of the installation grooves. A threaded hole is opened on the side of the wrench socket corresponding to the installation groove, and a fastening bolt is threadedly connected in the threaded hole. The fastening bolt abuts against the movable seat and is used to fix the movable seat in the installation groove. The movable seat can be installed in one of the two installation grooves according to needs, avoiding excessive space occupation when there are movable seats in both installation grooves.

[0019] Further, the healing cap anti - detachment mechanism includes a healing cap arc limiting rod. Two front - and - rear corresponding telescopic rods are detachably installed at one end of the wrench socket near the wrench sleeve. The two ends of a longitudinal support are respectively fixedly connected to the tops of the two telescopic rods. The longitudinal support is connected to the right ends of the two healing cap arc limiting rods through an opposing elastic component. The inner sides of the two healing cap arc limiting rods are arranged corresponding to each other, and healing cap bottom - edge arc limiting grooves are respectively opened on the inner sides of the two healing cap arc limiting rods. The installation groove is located between the two telescopic rods. The telescopic rods and the longitudinal support can be installed on the upper or lower side of the wrench socket according to needs. The telescopic rods can make the longitudinal support correspond to the bottom edge of the healing cap. The opposing elastic component makes the two healing cap arc limiting rods approach each other. After the two healing cap arc limiting rods approach each other, they are on the same circle. The two healing cap bottom - edge arc limiting grooves correspond to the bottom edge of the healing cap. When the center of the bottom of the healing cap is installed on the cross - shaped screwdriver head of the healing cap screwdriver, the bottom edge of the healing cap is located in the two healing cap bottom - edge arc limiting grooves, which can prevent the healing cap from falling off the cross - shaped screwdriver head. At the same time, there is a gap between the healing cap bottom - edge arc limiting groove and the bottom edge of the healing cap, avoiding a large frictional force between the inner wall of the healing cap bottom - edge arc limiting groove and the bottom edge of the healing cap.

[0020] Furthermore, the opposing elastic component includes a sliding control rod. Two longitudinal sliding grooves are formed on the side surface of the longitudinal support. Two longitudinal columns are fixedly connected to the two longitudinal sliding grooves respectively. One ends of the two longitudinal columns close to each other are slidably connected to the sliding holes on the two sliding control rods respectively. And the two sliding control rods are respectively slidably connected to the two corresponding longitudinal sliding grooves. The left ends of the two sliding control rods are respectively fixedly connected to the right ends of the two healing cap arc limiting rods. One ends of the two longitudinal columns away from each other are respectively sleeved with limiting compression springs. The right ends of the two sliding control rods respectively extend to the outer sides of the right ends of the two longitudinal sliding grooves, which is convenient for controlling the use of the two sliding control rods. The elastic force of the two limiting compression springs pushes the two sliding control rods to approach each other, so that the two healing cap arc limiting rods approach each other. When the distance between the two healing cap arc limiting rods is the closest, they are on the same circle. When it is necessary to let the two healing cap arc limiting rods leave the bottom edge of the healing cap, the two sliding control rods are separated against the elastic force of the two limiting compression springs, so that the two healing cap arc limiting rods are separated. Then the telescopic rod is shortened, and the bottom edge of the healing cap can leave from the two healing cap bottom edge arc limiting grooves.

[0021] Compared with the prior art, the beneficial effects of the auxiliary device for inserting and removing the healing cap of the present invention are as follows:

[0022] 1. The torsion of the torsion spring makes the left end of the pressure rod move downward, so that the semi-circular groove on the pressure rod cooperates with the bottom end of the screwdriver rod in the healing cap screwdriver. Thus, the left end of the pressure rod presses down the boss in the healing cap screwdriver, preventing the healing cap screwdriver from detaching from the top of the wrench socket ring, ensuring that the healing cap screwdriver is stably installed in the wrench socket ring, and avoiding the wedge-shaped limiting end from disengaging from the twisting groove due to incorrect twisting angle, so as to prevent the healing cap screwdriver from detaching from the wrench socket ring.

[0023] 2. The opposing elastic component makes the two healing cap arc limiting rods approach each other. After the two healing cap arc limiting rods approach each other, they are on the same circle. The two healing cap bottom edge arc limiting grooves correspond to the bottom edge of the healing cap. When the center of the bottom of the healing cap is installed on the cross-shaped screwdriver head of the healing cap screwdriver, the bottom edge of the healing cap is in the two healing cap bottom edge arc limiting grooves, which can prevent the healing cap from falling off the cross-shaped screwdriver head.

[0024] 3. It can stably install the healing cap screwdriver on the twisting wrench mechanism, and can limit the bottom of the healing cap during the process of inserting or removing the healing cap, preventing the healing cap from falling off the end of the healing cap screwdriver, and avoiding the healing cap screwdriver or the healing cap from falling into the deep part of the oral cavity and being accidentally aspirated by the dental implant patient, with good safety.

Detailed implementation mode

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Example 1, please refer to Figures 1 to 11, this embodiment provides a technical solution: an auxiliary device for inserting and removing a healing cap, including a twisting wrench mechanism 1. The twisting wrench mechanism 1 includes a wrench socket 11, a wrench ring 12, a limiting post 13, a pushing disk 14, a reset compression spring 15, an external thread sleeve 16, an end ring 17 and a wedge-shaped limiting end 18. The left end of the wrench socket 11 is integrally connected with the wrench ring 12. The wrench ring 12 is provided with a limiting through groove at a position corresponding to the middle of the wrench socket 11. The limiting post 13 is inserted into the limiting through groove. One end of the limiting post 13 located inside the wrench ring 12 is provided with a wedge-shaped limiting end 18. One end of the limiting post 13 located inside the wrench socket 11 is fixedly connected with the pushing disk 14. The inner side of the right end of the wrench socket 11 is threadedly connected with the external thread sleeve 16. The outer peripheral side of the right end of the external thread sleeve 16 is integrally connected with the end ring 17. A reset compression spring 15 is installed inside the wrench socket 11. The two ends of the reset compression spring 15 respectively abut against the pushing disk 14 and the end of the external thread sleeve 16. A healing cap screwdriver 4 is installed inside the wrench ring 12. One side of the wedge-shaped limiting end 18 is provided with a clamping plane and the other side is provided with an inclined plane;

[0039] The healing cap screwdriver 4 includes a cylindrical tool holder 41, a twisting slot 42, a circular retaining disk 43, a boss 44 and a screwdriver rod 45. The top of the cylindrical tool holder 41 is fixedly connected with the circular retaining disk 43. The diameter of the cylindrical tool holder 41 is the same as the diameter of the inner circular groove of the wrench ring 12, and the diameter of the circular retaining disk 43 is larger than the diameter of the cylindrical tool holder 41. The center of the top of the circular retaining disk 43 is fixedly connected with the bottom end of the screwdriver rod 45 through the boss 44. The outer peripheral side of the cylindrical tool holder 41 is annularly and arrayedly provided with twisting slots 42. The cylindrical tool holder 41 is installed in the inner circular groove of the wrench ring 12. The setting of the circular retaining disk 43 can prevent the cylindrical tool holder 41 from falling downward when installed in the wrench ring 12 and prevent the healing cap screwdriver 4 from detaching from the bottom of the wrench ring 12. The elastic force of the reset compression spring 15 causes the wedge-shaped limiting end 18 at the end of the limiting post 13 to be clamped with the twisting slot 42. By rotating the wrench ring 12 clockwise with the wrench socket 11, the stable clamping of the wrench ring 12 through the clamping plane of the wedge-shaped limiting end 18 and the twisting slot 42 can drive the cylindrical tool holder 41 to rotate, thereby driving the screwdriver rod 45 to rotate clockwise through the boss 44. A cross-shaped screwdriver head is provided at the top of the screwdriver rod 45. The cross-shaped screwdriver head cooperates with the center of the end of the healing cap 7, so that the healing cap 7 can be screwed and installed onto the implant in the alveolar bone. By rotating the wrench ring 12 counterclockwise with the wrench socket 11, the inclined plane of the wedge-shaped limiting end 18 contacts the edge of the twisting slot 42. Due to the large friction force at the connection between the implant and the healing cap 7, the inclined plane of the wedge-shaped limiting end 18 and the edge of the twisting slot 42 slide relative to each other, causing the wedge-shaped limiting end 18 to retract into the limiting through groove through the limiting post 13 against the elastic force of the reset compression spring 15. During this process, the cylindrical tool holder 41 does not rotate. Repeatedly pulling the wrench socket 11 completes the insertion operation of the healing cap 7.

[0040] It also includes a twisting direction control mechanism 2, a torque limiting mechanism 3, a screwdriver anti - detachment mechanism 5, and a healing cap anti - detachment mechanism 6;

[0041] One end of the twisting direction control mechanism 2 is connected to the middle of the right side of the push disk 14, and the other end of the twisting direction control mechanism 2 is connected to the end ring 17;

[0042] The torque limiting mechanism 3 is installed at the right end of the wrench socket 11, and the torque limiting mechanism 3 is connected to the twisting direction control mechanism 2;

[0043] The screwdriver anti - detachment mechanism 5 is installed at one end of the wrench ring 12 close to the wrench socket 11;

[0044] The screwdriver anti - detachment mechanism 5 includes a detachable installation component, a movable seat 53, a longitudinal rotating shaft 54, a movable block 55, a torsion spring 56, a pressure rod 57, and a semi - circular groove 58. One end of the wrench ring 12 close to the wrench socket 11 is installed with a movable seat 53 through the detachable installation component. The movable seat 53 is movably connected to the movable block 55 through the longitudinal rotating shaft 54. One end of the side of the movable block 55 is fixedly connected to one end of the pressure rod 57. The other end of the pressure rod 57 is provided with a semi - circular groove 58. A torsion spring 56 is installed on the longitudinal rotating shaft 54, and the two ends of the torsion spring 56 are respectively connected to the movable seat 53 and the movable block 55. The torsion of the torsion spring 56 makes the left end of the pressure rod 57 move downward, so that the semi - circular groove 58 on the pressure rod 57 cooperates with the bottom end of the screwdriver rod 45 in the healing cap screwdriver 4. Thus, the left end of the pressure rod 57 presses down the boss 44 in the healing cap screwdriver 4, preventing the healing cap screwdriver 4 from detaching from the top of the wrench ring 12, ensuring that the healing cap screwdriver 4 is stably installed in the wrench ring 12, and avoiding the wedge - shaped limiting end 18 from detaching from the twisting slot 42 due to incorrect twisting angle, resulting in the detachment of the healing cap screwdriver 4 from the wrench ring 12, especially in the scenario where the cross - shaped screwdriver head of the healing cap screwdriver 4 is used downward.

[0045] The detachable installation component includes an installation groove 51 and a fastening bolt 52. Two installation grooves 51 are respectively opened on the upper and lower sides of the middle part of one end of the wrench ring 12 close to the wrench socket 11. A movable seat 53 is installed in one of the installation grooves 51. A threaded hole is opened on the side surface of the wrench ring 12 corresponding to the installation groove 51, and a fastening bolt 52 is threadedly connected in the threaded hole. The fastening bolt 52 abuts against the movable seat 53. The fastening bolt 52 is used to fix the movable seat 53 in the installation groove 51. The movable seat 53 can be installed in one of the two installation grooves 51 according to needs, avoiding excessive space occupation when there are movable seats 53 in both installation grooves 51.

[0046] The healing cap anti - detachment mechanism 6 is installed on the wrench ring 12.

[0047] The anti - detachment mechanism 6 of the healing cap includes a telescopic rod 64, a longitudinal support 65, a circular - arc limiting rod 610 of the healing cap, a circular - arc limiting groove 611 at the bottom edge of the healing cap, and an opposing elastic component. At one end of the wrench sleeve 12 close to the wrench barrel 11, two telescopically corresponding rod 64 are detachably installed. The tops of the two telescopic rods 64 are respectively fixedly connected to both ends of the longitudinal support 65. The longitudinal support 65 is connected to the right ends of the two circular - arc limiting rods 610 of the healing cap through the opposing elastic component. The inner sides of the two circular - arc limiting rods 610 of the healing cap are arranged corresponding to each other, and circular - arc limiting grooves 611 at the bottom edge of the healing cap are respectively formed on the inner sides of the two circular - arc limiting rods 610 of the healing cap.

[0048] The anti - detachment mechanism 6 of the healing cap further includes a vertical through - hole 61, a mounting bolt 62, and a mounting column 63. On the front and rear sides of one end of the wrench sleeve 12 close to the wrench barrel 11, two vertical through - holes 61 are respectively formed. Two mounting columns 63 are respectively inserted into the two vertical through - holes 61. At a position corresponding to the middle of the vertical through - hole 61 on the side surface of the wrench sleeve 12, a locking screw hole is formed. A mounting bolt 62 is threadedly connected to the locking screw hole. The mounting bolt 62 abuts against the mounting column 63 in the vertical through - hole 61. The ends of the two mounting columns 63 are respectively fixedly connected to the bottom ends of the telescopic rods 64, thereby realizing the detachable connection between the two telescopic rods 64 and the wrench sleeve 12.

[0049] The installation groove 51 is located between the two telescopic rods 64. The telescopic rod 64 and the longitudinal support 65 can be installed on the upper side or the lower side of the wrench sleeve 12 as required. The telescopic movement of the telescopic rod 64 can make the longitudinal support 65 correspond to the bottom edge of the healing cap 7. The opposing elastic component makes the two circular - arc limiting rods 610 of the healing cap approach each other. After the two circular - arc limiting rods 610 of the healing cap approach each other, they are on the same circle. The two circular - arc limiting grooves 611 at the bottom edge of the healing cap correspond to the bottom edge of the healing cap 7. When the center of the bottom of the healing cap 7 is installed on the cross - shaped screwdriver head of the healing cap screwdriver 4, the bottom edge of the healing cap 7 is located in the two circular - arc limiting grooves 611 at the bottom edge of the healing cap, which can prevent the healing cap 7 from falling off the cross - shaped screwdriver head. At the same time, there is a gap between the circular - arc limiting groove 611 at the bottom edge of the healing cap and the bottom edge of the healing cap 7, avoiding a large frictional force between the inner wall of the circular - arc limiting groove 611 at the bottom edge of the healing cap and the bottom edge of the healing cap 7.

[0050] The opposing elastic component includes longitudinal sliding grooves 66, longitudinal columns 67, limiting compression springs 68 and sliding control rods 69. Two longitudinal sliding grooves 66 are provided on the side surface of the longitudinal support 65. Two longitudinal columns 67 are fixedly connected in the two longitudinal sliding grooves 66 respectively. The ends of the two longitudinal columns 67 close to each other are respectively slidably connected to the sliding holes on the two sliding control rods 69, and the two sliding control rods 69 are respectively slidably connected to the two corresponding longitudinal sliding grooves 66. The left ends of the two sliding control rods 69 are respectively fixedly connected to the right ends of the two healing cap arc limiting rods 610. The ends of the two longitudinal columns 67 away from each other are respectively sleeved with limiting compression springs 68. The right ends of the two sliding control rods 69 respectively extend to the outer sides of the right ends of the two longitudinal sliding grooves 66, which is convenient for controlling the use of the two sliding control rods 69. The elastic forces of the two limiting compression springs 68 push the two sliding control rods 69 to approach each other, so that the two healing cap arc limiting rods 610 approach each other. When the distance between the two healing cap arc limiting rods 610 is the closest, they are on the same circle. When it is necessary to make the two healing cap arc limiting rods 610 leave the bottom edge of the healing cap 7, the two sliding control rods 69 are separated against the elastic forces of the two limiting compression springs 68, so that the two healing cap arc limiting rods 610 are separated. Then the telescopic rod 64 is shortened, and the bottom edge of the healing cap 7 can leave from the two healing cap bottom edge arc limiting grooves 611.

[0051] During use, the external thread sleeve 16 can be twisted with the help of the end ring 17, so as to facilitate the disassembly and assembly of the external thread sleeve 16. The external thread sleeve 16 presses against the reset compression spring 15, and the reset compression spring 15 pushes the limit post 13 to move leftward through the push plate 14, so that the wedge-shaped limit end 18 at the left end of the limit post 13 extends into the wrench sleeve 12 and cooperates with the healing cap screwdriver 4 to install the healing cap screwdriver 4 in the wrench sleeve 12. The wedge-shaped limit end 18 is clamped with the healing cap screwdriver 4. Then, the healing cap 7 is cooperatively installed on the cross-shaped screwdriver head at the top of the healing cap screwdriver 4. Then, the screw at the top of the healing cap 7 is aligned with the screw hole of the implant in the alveolar bone. By rotating the wrench sleeve 11 clockwise, the wrench sleeve 12 drives the healing cap screwdriver 4 and the healing cap 7 to rotate clockwise by a certain angle through the clamping plane of the wedge-shaped limit end 18, and the healing cap 7 is screwed into the screw hole of the implant in the alveolar bone. Then, by rotating the wrench sleeve 11 counterclockwise, since there is a large frictional force in the threaded connection between the implant and the healing cap 7, the healing cap 7 and the healing cap screwdriver 4 will not rotate counterclockwise with the wrench sleeve 12. At the same time, the inclined surface of the wedge-shaped limit end 18 enables the wedge-shaped limit end 18 to retract into the limit through groove by overcoming the elastic force of the reset compression spring 15 through the limit post 13 and the push plate 14. At this time, the healing cap screwdriver 4 does not rotate with the wrench sleeve 12 in the wrench sleeve 12. By reciprocally moving the wrench sleeve 11, the healing cap screwdriver 4 can be intermittently rotated clockwise, so that the healing cap screwdriver 4 drives the healing cap 7 to be intermittently rotated clockwise, and the insertion operation of the healing cap 7 can be completed. By rotating the limit post 13 and the wedge-shaped limit end 18 by 180 degrees with the help of the twisting direction control mechanism 2, the positions of the clamping plane and the inclined surface on the wedge-shaped limit end 18 are exchanged. At this time, by rotating the wrench sleeve 11 counterclockwise, the healing cap screwdriver 4 and the healing cap 7 can be driven to rotate counterclockwise, so as to unscrew the healing cap 7. By rotating the wrench sleeve 11 clockwise, the healing cap screwdriver 4 and the healing cap 7 will not rotate. By reciprocally moving the wrench sleeve 11, the healing cap 7 can be taken out. The setting of the torque limiting mechanism 3 can limit the torque when the healing cap 7 is inserted. If the torque exceeds the limit value for rotating the healing cap 7, the wedge-shaped limit end 18 will retract into the limit through groove, so that the clamping plane of the wedge-shaped limit end 18 can no longer act on the healing cap screwdriver 4, and the clamping action of the clamping plane of the wedge-shaped limit end 18 on the healing cap screwdriver 4 is stopped. At this point, it indicates that the healing cap 7 has been installed in place. The setting of the screwdriver anti-detachment mechanism 5 prevents the healing cap screwdriver 4 from detaching from the wrench sleeve 12 due to the improper angle of using the wrench sleeve 11 and the wrench sleeve 12. The healing cap anti-detachment mechanism 6 limits the bottom of the healing cap to prevent the healing cap from detaching from the cross-shaped screwdriver head at the top of the healing cap screwdriver 4, ensuring that the healing cap screwdriver 4 or the healing cap will not fall in the oral cavity.

[0052] Example 2, please refer to Figures 1 to 11, this embodiment provides a technical solution: an auxiliary device for inserting and removing a healing cap. This embodiment is a further explanatory description of Embodiment 1;

[0053] The twisting direction control mechanism 2 includes a control cross shaft 21, a transverse groove 22, a rotation control sleeve 23, a transverse sliding bar 24, a control rotating ring 25, a friction protrusion 26, a control bolt 27, and a locking round hole 28. The left end of the control cross shaft 21 is fixedly connected to the middle of the right side of the push disk 14. The right end of the control cross shaft 21 passes through the center of the external thread sleeve 16 and extends to the outside of the right end of the external thread sleeve 16. A transverse groove 22 is provided on the outside of the right end of the control cross shaft 21. A rotation control sleeve 23 is slidably sleeved on the right end of the control cross shaft 21. A transverse sliding bar 24 slidably connected to the transverse groove 22 is arranged on the inner side of the rotation control sleeve 23. A control rotating ring 25 is fixedly sleeved on the outside of the right end of the rotation control sleeve 23. The control rotating ring 25 is located on the right side of the end ring 17. Friction protrusions 26 are arranged in a circumferential array on the outer peripheral side of the control rotating ring 25. A transverse control bolt 27 is threadedly connected to the edge of the control rotating ring 25. Two locking round holes 28 symmetric about the center of the end ring 17 are provided at the right end of the end ring 17. The left end of the control bolt 27 extends into one of the locking round holes 28. The control cross shaft 21 can move left and right along with the push disk 14 and the limit post 13. The rotation control sleeve 23 realizes left and right sliding with the control cross shaft 21 through the transverse sliding bar 24 and the transverse groove 22. The rotation control sleeve 23 can be driven to rotate by means of the friction protrusions 26, so as to drive the control cross shaft 21 and the limit post 13 to rotate. When it is necessary to rotate the limit post 13 and the wedge-shaped limit end 18 by 180 degrees to change the direction of the twisting force of the twisting wrench mechanism 1, loosen the control bolt 27 to make the control bolt 27 leave the current locking round hole 28, and then rotate the rotation control sleeve 23 by 180 degrees through the friction protrusions 26. The rotation control sleeve 23 drives the control cross shaft 21, the limit post 13, and the wedge-shaped limit end 18 to rotate by 180 degrees through the transverse sliding bar 24 and the transverse groove 22. Then tighten the control bolt 27, and the control bolt 27 extends into the other locking round hole 28 to complete the locking of the rotation control sleeve 23, so that the control cross shaft 21, the limit post 13, and the wedge-shaped limit end 18 are stabilized. At this time, the swapping of the clamping plane and the inclined plane positions of the wedge-shaped limit end 18 is completed.

[0054] Embodiment 3, please refer to Figures 1 to 11 , this embodiment provides a technical solution: an auxiliary device for inserting and removing a healing cap. This embodiment is a further explanatory description of Embodiment 2;

[0055] The torque limiting mechanism 3 includes an arc-shaped long plate 31, a limiting end cap 32, a pull ring 33, a first movable shaft 35, a pull rod 36, a second movable shaft 37, a support column 38, a rotating rod 39, a mounting bracket 310, an end handle 311, an elastic resistance assembly, and a torque limiting adjustment assembly. The upper and lower sides of the right end of the wrench socket 11 are respectively fixedly connected to the left ends of two arc-shaped long plates 31. A pull ring 33 is slidably sleeved on the outer peripheral side of the right end of the control cross shaft 21, and a limiting end cap 32 is fixedly connected to the right end face of the control cross shaft 21. The upper and lower sides of the pull ring 33 are respectively movably connected to the left ends of two pull rods 36 through two first movable shafts 35. The right ends of the two pull rods 36 are respectively movably connected to the left end of the rotating rod 39 through two second movable shafts 37. The right end of the rotating rod 39 is rotatably connected to the top of the support column 38. The bottom of the support column 38 is fixedly connected to the lower arc-shaped long plate 31. The front and rear sides of the left end of the rotating rod 39 are respectively fixedly connected to the left ends of two mounting brackets 310. The right ends of the two mounting brackets 310 are both fixedly connected to the left end of the end handle 311. The pull ring 33 is connected to the elastic resistance assembly, and a torque limiting adjustment assembly is installed on the elastic resistance assembly.

[0056] During use, hold the end handle 311 and then rotate it clockwise. The end handle 311 can drive the rotating rod 39 to rotate relative to the support column 38 through the mounting bracket 310. The rotating rod 39 pulls the pull ring 33 to the right through the pull rod 36. Due to the existence of the limiting end cap 32, the pull ring 33 and the control cross shaft 21 will not separate. When the pulling force of the pull rod 36 on the pull ring 33 is sufficient to overcome the resistance of the elastic resistance assembly and the return compression spring 15, the pull ring 33 pulls the control cross shaft 21 to the right with the help of the limiting end cap 32. The control cross shaft 21 can pull the limiting column 13 and the wedge-shaped limiting end 18 to the right, and finally the wedge-shaped limiting end 18 will retract into the limiting through groove. At this time, the clamping plane originally acting on the healing cap screwdriver 4 will separate from the healing cap screwdriver 4, and the wrench socket 12 cannot continue to twist the healing cap screwdriver 4 when rotated clockwise. The torque limiting adjustment assembly can change the resistance of the elastic resistance assembly. When the force of pulling the end handle 311 is too large, the healing cap screwdriver 4 and the healing cap 7 cannot be twisted continuously. As a protection measure, it can avoid excessive torque on the healing cap screwdriver 4 and the healing cap 7 from damaging the healing cap 7 or the implant, and can also avoid harming the alveolar bone of the dental implant patient. It should be noted that the torque limiting mechanism 3 is mainly used in the final stage of the implantation process of the healing cap 7 to limit the maximum applied torque. In the initial stage of the implantation of the healing cap 7, generally the wrench socket 11 is pulled instead of the end handle 311. This can avoid the friction between the pull ring 33 and the control cross shaft 21 when the end handle 311 is pulled counterclockwise from affecting the smooth retraction of the limiting column 13 and the wedge-shaped limiting end 18 into the limiting through groove. When the wrench socket 11 and the wrench ring 12 are rotated counterclockwise, the limiting column 13, the wedge-shaped limiting end 18, and the control cross shaft 21 move to the right. At this time, the limiting end cap 32 also moves to the right accordingly, and the limiting end cap 32 has a moving space between the pull ring 33 and the rotating rod 39.

[0057] The elastic resistance assembly includes a connecting rod 34, a slide plate 312, a support seat 313, a horizontal sliding column 314 and a torsion limiting compression spring 315. The bottom of the upper arc long plate 31 is fixedly connected to two supporting seats 313, and two horizontal sliding columns 314 are respectively fixedly connected between the two supporting seats 313. The slide plate 312 is slidably connected to the two horizontal sliding columns 314, and the slide plate 312 is fixedly connected to the pull ring 33 through two connecting rods 34. The right ends of the two horizontal sliding columns 314 are respectively sleeved with a torsion limiting compression spring 315. The support seat 313 is used to install the horizontal sliding column 314, and the two torsion limiting compression springs 315 provide resistance to the pull ring 33 when it moves to the right with the help of the slide plate 312 and the connecting rod 34.

[0058] The torque limiting adjustment assembly includes a limit control plate 316 and a butterfly bolt 317. The two sliding holes on the limit control plate 316 are respectively slidably connected to the right ends of the two horizontal sliding columns 314. The torque limiting compression spring 315 is located between the slide plate 312 and the limit control plate 316. The middle part of the right support seat 313 is threadedly connected with a horizontal butterfly bolt 317, and the left end of the butterfly bolt 317 is pressed against the left side of the limit control plate 316. The butterfly bolt 317 is twisted clockwise, and the butterfly bolt 317 moves to the left relative to the support seat 313, thereby pushing the limit control plate 316 to move to the left. With the help of the limit control plate 316, the torque limiting compression spring 315 can be continuously compressed, so that the torque limiting compression spring 315 provides greater resistance to the rightward movement of the pull ring 33. It takes a greater force to pull the end handle 311 to make the wedge-shaped limit end head 18 retract into the limit through groove, and a larger torque is applied to the healing cap 7 to stop. Then, by twisting the butterfly bolt 317 counterclockwise, the butterfly bolt 317 moves to the right relative to the support seat 313, and the limit control plate 316 moves to the right along the cross sliding column 314. The resistance of the compression torque limiting compression spring 315 to the rightward movement of the pull ring 33 becomes smaller, and the end handle 311 can be turned with less force to allow the wedge-shaped limit end 18 to retract into the limit through groove, and the healing cap 7 will stop when a small torque is applied. Therefore, the butterfly bolt 317 can be adjusted according to the torque requirement when the healing cap 7 is installed in place.
