Description

Technical Field

[0001] The invention relates to the technical field of artificial tooth implants, in particular to an auxiliary device for inserting and removing a healing cap. Background Art

[0002] At present, artificial dental implants are divided into three steps. The first step is to implant the 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 gums. The gums will heal to the side walls of the healing cap and form a gingival healing surface; after the implant and the alveolar bone are tightly fitted, the third step is to remove the healing cap and install the restoration base and denture, thus completing the entire process of artificial dental implants.

[0003] The installation of the healing cap requires the use of a screwdriver and a wrench in the narrow space of the mouth. When inserting or removing the healing cap, if the operation is not careful, the screwdriver or the healing cap will fall deep into the mouth, and the patient who is lying in the dental implant position may easily inhale it, which may 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 the insertion and removal of a healing cap, which can allow a healing cap screwdriver to be stably installed on a twist wrench mechanism, and can limit the bottom of the healing cap during the insertion or removal of the healing cap to prevent the healing cap from falling from the end of the healing cap screwdriver, and can prevent the healing cap screwdriver or the healing cap from falling into the deep oral cavity and being accidentally inhaled by the implant recipient. It has good safety and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a healing cap insertion and removal auxiliary device, comprising a twisting wrench mechanism, the twisting wrench mechanism includes a wrench sleeve, the left end of the wrench sleeve is connected to a wrench ring, the wrench ring is provided with a limited through groove corresponding to the middle of the wrench sleeve, a limited column is inserted in the limited through groove, one end of the limit column located in the wrench ring is provided with a wedge-shaped limit end head, one end of the limit column located in the wrench sleeve is fixedly connected to a push disk, the inner side of the right end of the wrench sleeve is threadedly connected to an external threaded sleeve, the outer peripheral side of the right end of the external threaded sleeve is connected to an end ring, a reset compression spring is installed in the wrench sleeve, a healing cap screwdriver is installed in the wrench ring, and also includes: A twisting direction control mechanism, one end of which is connected to the middle portion of the right side of the push disk, and the other end of which is connected to the end ring; The torque limiting mechanism is installed at the right end of the wrench sleeve, and the torque limiting mechanism is connected to the torsion direction control mechanism; The screwdriver anti-drop mechanism is installed on the end of the wrench ring close to the wrench sleeve; The healing cap anti-drop mechanism is installed on the wrench ring.

[0006] One side of the wedge-shaped limiting end is provided with a clamping plane and the other side is provided with an inclined surface. The external threaded sleeve can be twisted with the help of the end ring, so as to facilitate the disassembly and assembly of the external threaded sleeve. The external threaded sleeve is pressed against the reset compression spring, and the reset compression spring pushes the limiting column to the left through the pushing plate, so that the wedge-shaped limiting end at the left end of the limiting column is inserted into the wrench ring and cooperates with the healing cap screwdriver. The healing cap screwdriver is installed in the wrench ring, the wedge-shaped limiting end is clamped with the healing cap screwdriver, and then the healing cap is installed on the M-shaped screwdriver head at the top of the healing cap screwdriver, and then the top screw of the healing cap is aligned with the screw hole of the implant in the alveolar bone, and the wrench is turned clockwise with the help of the wrench socket. The wrench ring drives the healing cap screwdriver and the healing cap to rotate clockwise for a certain angle through the clamping plane of the wedge-shaped limiting end, and the healing cap is screwed into the screw hole of the implant in the alveolar bone. Then, the wrench ring is rotated counterclockwise with the help of the wrench socket. The implant and the healing cap are threadedly connected, so there is a large friction force. Therefore, the healing cap and the healing cap screwdriver will not rotate counterclockwise with the wrench ring. At the same time, the inclined surface of the wedge-shaped limiting end allows the wedge-shaped limiting end to overcome the elastic force of the reset compression spring through the limiting column and the pushing disk and retract into the limiting groove. At this time, the healing cap screwdriver does not rotate with the wrench ring in the wrench ring, and the wrench socket is pulled back and forth to allow the healing cap screw to rotate. The knife rotates clockwise intermittently, so that the healing cap screwdriver drives the healing cap to rotate clockwise intermittently, and the insertion operation of the healing cap can be completed. With the help of the twisting direction control mechanism, the limit column and the wedge-shaped limit end are rotated 180 degrees, and the clamping plane and the inclined surface on the wedge-shaped limit end are swapped. At this time, the healing cap screwdriver and the healing cap can be driven to rotate counterclockwise by rotating the wrench ring counterclockwise through the wrench socket, thereby loosening the healing cap. By rotating the wrench ring clockwise with the help of the wrench socket, the healing cap screwdriver and the healing cap will not rotate. The healing cap can be taken out by reciprocating the wrench socket. The setting of the torque limiting mechanism can limit the insertion of the healing cap. The torque when the cap is turned on, if the torque exceeds the limit value of rotating the healing cap, the wedge-shaped limit end will retract into the limit slot, so that the clamping plane of the wedge-shaped limit end can no longer act on the healing cap screwdriver, and the clamping effect of the clamping plane of the wedge-shaped limit end on the healing cap screwdriver is stopped. At this point, it means that the healing cap has been installed in place. The setting of the screwdriver anti-offset mechanism avoids the use of the wrench socket and the wrench ring at a bad angle causing the healing cap screwdriver to separate from the wrench ring. The healing cap anti-offset mechanism limits the bottom of the healing cap to avoid the healing cap and the Pozidriv screwdriver head on the top of the healing cap screwdriver from separating, ensuring that the healing cap screwdriver or the healing cap will not fall off in the mouth.

[0007] Furthermore, the torsion direction control mechanism includes a control transverse axis, the middle part of the right side of the pushing plate is fixedly connected to the left end of the control transverse axis, the right end of the control transverse axis passes through the center of the external threaded sleeve and extends to the outside of the right end of the external threaded sleeve, a transverse groove is provided on the outside of the right end of the control transverse axis, the right end of the control transverse axis is slidably sleeved with a rotating control sleeve, the inner side of the rotating control sleeve is provided with a transverse sliding bar slidably connected to the transverse groove, the outer side of the right end of the rotating control sleeve is fixedly sleeved with a control swivel, the edge of the control swivel is threadedly connected with a transverse control bolt, the right end of the end ring is provided with two locking circular holes symmetrical about the center of the end ring, and the left end of the control bolt extends into one of the locking circular holes. The control horizontal axis can move left and right with the pushing plate and the limit column. The rotating control sleeve can slide left and right with the control horizontal axis through the horizontal sliding bar and the horizontal groove, driving the rotating control sleeve to rotate, thereby driving the control horizontal axis and the limit column to rotate. When the limit column and the wedge-shaped limit end need to be rotated 180 degrees to change the direction of the twisting force of the twist wrench mechanism, loosen the control bolt to let the control bolt leave the current locking circular hole, and then rotate the rotating control sleeve 180 degrees through the friction protrusion. The rotating control sleeve drives the control horizontal axis, the limit column and the wedge-shaped limit end to rotate 180 degrees through the horizontal sliding bar and the horizontal 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, so that the control horizontal axis, the limit column and the wedge-shaped limit end are stabilized. At this time, the replacement of the clamping plane and the inclined surface position of the wedge-shaped limit end is completed.

[0008] Furthermore, the torque limiting mechanism includes an arc long plate, and the upper and lower sides of the right end of the wrench sleeve are respectively fixedly connected to the left ends of the two arc long plates, the outer peripheral side of the right end of the control horizontal axis is slidably sleeved with a pull ring, and the right end face of the control horizontal axis is fixedly connected to the limited end cap, the upper and lower sides of the pull ring are respectively movably connected to the left ends of the two pulling rods through two movable shafts, and the right ends of the two pulling rods are respectively movably connected to the left end of the rotating rod through two movable shafts, the right end of the rotating rod is rotatably connected to the top of the pillar, and the bottom of the pillar is fixedly connected to the arc long plate on the lower side, the front and rear sides of the left end of the rotating rod are respectively fixedly connected to the left ends of the two mounting frames, and the right ends of the two mounting frames are fixedly connected to the left end of the end handle, and the pull ring is connected to the elastic resistance component, and the torque limiting adjustment component is installed on the elastic resistance component.

[0009] When in use, hold the end handle and turn it clockwise. The end handle can drive the rotating rod to rotate relative to the pillar through the mounting bracket, and the rotating rod pulls the pull ring to the right through the pulling rod. Due to the existence of the limiting end cap, the pull ring and the control horizontal axis will not be separated. When the pulling force of the pulling 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 horizontal axis to the right with the help of the limiting end cap. The control horizontal axis can pull the limiting column and the wedge-shaped limiting end to the right, and finally the wedge-shaped limiting end will be retracted into the limiting through groove. At this time, the clamping plane originally acting on the healing cap screwdriver will be separated from the healing cap screwdriver, and the healing cap screwdriver cannot be twisted by turning the wrench ring clockwise. The torque limiting adjustment component can change the resistance of the elastic resistance component. When the end handle is turned too hard, it cannot be turned. Continue to twist the healing cap screwdriver and the healing cap as a means of protection to avoid excessive torque on the healing cap screwdriver and the healing cap to damage the healing cap or the implant, and to avoid hurting the alveolar bone of the implant recipient. It should be noted that the torque limiting mechanism is mainly used in the final stage of the healing cap insertion process to limit the maximum torque applied. In the initial stage of the healing cap insertion, the wrench socket is generally turned instead of the end handle. This can avoid the friction between the pull ring and the control horizontal axis when the end handle is turned counterclockwise to affect the limit column and the wedge-shaped limit end head from smoothly retracting into the limit groove, and when the wrench socket and the wrench ring are turned counterclockwise, the limit column, the wedge-shaped limit end head and the control horizontal axis move to the right, and at this time the limit end cap also moves to the right, and the limit end cap has a movable space between the pull ring and the rotating rod.

[0010] Furthermore, the elastic resistance assembly includes a slide plate, two support seats are fixedly connected to the bottom of the upper arc long plate, two cross-sliding columns are fixedly connected between the two support seats, the slide plate is slidably connected to the two cross-sliding columns, and the slide plate is fixedly connected to the pull ring through two connecting rods, and the right ends of the two cross-sliding columns are respectively sleeved with torsion limiting compression springs. The support seat is used to install the cross-sliding column, and the two torsion limiting compression springs provide resistance to the pull ring when it moves to the right with the help of the slide plate and the connecting rod.

[0011] 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.

[0012] 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.

[0013] Furthermore, the screwdriver anti-slip mechanism includes a pressure rod, and a movable seat is installed at one end of the spanner ring close to the spanner sleeve through a detachable installation component. The movable seat is movably connected to the movable block through a longitudinal rotation axis, and the side of the movable block is fixedly connected to one end of the pressure rod. A semicircular groove is provided at the other end of the pressure rod, and a torsion spring is installed on the longitudinal rotation axis. 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 allows the left end of the pressure rod to move downward, so that the semicircular groove on the pressure rod cooperates with the bottom end of the screwdriver rod in the healing cap screwdriver, thereby the left end of the pressure rod presses down the boss in the healing cap screwdriver to prevent the healing cap screwdriver from detaching from the top of the spanner ring, ensuring that the healing cap screwdriver is stably installed in the spanner ring, and preventing the wedge-shaped limit end from detaching from the twisting slot due to incorrect twisting angle, thereby causing the healing cap screwdriver to detach from the spanner ring, especially in the scenario where the Pozidriv screwdriver head of the healing cap screwdriver is used downward.

[0014] Furthermore, the detachable mounting assembly includes a mounting groove, and two mounting grooves are respectively provided on the upper and lower sides of the middle part of one end of the wrench ring close to the wrench sleeve, a movable seat is installed in one of the mounting grooves, and a threaded hole is provided on the side of the wrench ring corresponding to the position of the mounting groove, and a fastening bolt is threadedly connected in the threaded hole, and the fastening bolt presses the movable seat tightly, and the fastening bolt is used to fix the movable seat in the mounting groove, and the movable seat can be installed in one of the two mounting grooves as needed to avoid occupying too much space when there are movable seats in both mounting grooves.

[0015] Furthermore, the healing cap anti-detachment mechanism includes a healing cap arc limit rod, and two front and rear corresponding telescopic rods are detachably installed on one end of the wrench ring close to the wrench sleeve. The tops of the two telescopic rods are respectively fixedly connected to the two ends of the longitudinal support, and the longitudinal support is connected to the right ends of the two healing cap arc limit rods through opposing elastic components. The inner sides of the two healing cap arc limit rods are arranged corresponding to each other, and the inner sides of the two healing cap arc limit rods are respectively provided with arc limit grooves on the bottom edge of the healing cap. The mounting 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 ring as needed. The telescopic rod can be extended and retracted to allow the longitudinal support to correspond to the bottom edge of the healing cap. The opposing elastic components allow the two arc limit rods of the healing cap to approach each other. After the two arc limit rods of the healing caps are approached, they are on the same circle. The two arc limit grooves on the bottom edges of the healing caps correspond to the bottom edges of the healing caps. When the bottom center of the healing cap is installed on the Pozidriv screwdriver head of the healing cap screwdriver, the bottom edge of the healing cap is in the two arc limit grooves on the bottom edges of the healing cap, which can prevent the healing cap from falling off the Pozidriv screwdriver head. At the same time, there is a gap between the arc limit groove on the bottom edge of the healing cap and the bottom edge of the healing cap, which prevents the inner wall of the arc limit groove on the bottom edge of the healing cap and the bottom edge of the healing cap from having a large friction force with the bottom edge of the healing cap.

[0016] Furthermore, the opposing elastic component includes a sliding control rod, and two longitudinal sliding grooves are provided on the side of the longitudinal support, and two longitudinal columns are fixedly connected in the two longitudinal sliding grooves respectively. The ends of the two longitudinal columns close to each other are slidingly connected to the sliding holes on the two sliding control rods respectively, and the two sliding control rods are slidingly connected to the two corresponding longitudinal sliding grooves respectively. The left ends of the two sliding control rods are fixedly connected to the right ends of the two healing cap arc limit rods respectively, and the ends of the two longitudinal columns far away from each other are respectively sleeved with limiting compression springs. The right ends of the two sliding control rods extend to the outside of the right ends of the two longitudinal sliding grooves respectively, which is convenient for controlling the use of the two sliding control rods. The elastic force of the two limit compression springs pushes the two sliding control rods closer to each other, thereby allowing the two healing cap arc limit rods to approach each other. When the two healing cap arc limit rods are closest to each other, they are on the same circle. When the two healing cap arc limit rods need to leave the bottom edge of the healing cap, the two sliding control rods overcome the elastic force of the two limit compression springs and separate, thereby allowing the two healing cap arc limit rods to separate, and then the telescopic rod is shortened, and the bottom edge of the healing cap can leave the two healing cap bottom edge arc limit grooves.

[0017] Compared with the prior art, the beneficial effects of the insertion and removal auxiliary device of the healing cap are: 1. The torsion force of the torsion spring allows the left end of the pressure rod to move downward, so that the semicircular groove on the pressure rod cooperates with the bottom end of the screwdriver rod in the healing cap screwdriver. The left end of the pressure rod presses down on the boss in the healing cap screwdriver to prevent the healing cap screwdriver from detaching from the top of the wrench ring, ensuring that the healing cap screwdriver is stably installed in the wrench ring, and preventing the wedge-shaped limit end from detaching from the twisting slot due to incorrect twisting angle, causing the healing cap screwdriver to detach from the wrench ring.

[0018] 2. The opposing elastic components allow the two arc limit rods of the healing caps to approach each other. After the two arc limit rods of the healing caps are approached, they are on the same circle. The two arc limit grooves on the bottom edges of the healing caps correspond to the bottom edges of the healing caps. When the bottom center of the healing cap is installed on the Pozidriv screwdriver head of the healing cap screwdriver, the bottom edge of the healing cap is in the two arc limit grooves on the bottom edges of the healing caps, which can prevent the healing cap from falling off the Pozidriv screwdriver head.

[0019] 3. The healing cap screwdriver can be stably mounted on the twist wrench mechanism, and the bottom of the healing cap can be limited during the insertion or removal of the healing cap to prevent the healing cap from falling from the end of the healing cap screwdriver. The healing cap screwdriver or the healing cap can be prevented from falling into the deep oral cavity and being accidentally inhaled by the implant recipient, which has good safety.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For example, see Figures 1 to 11The present embodiment provides a technical solution: a healing cap insertion and removal auxiliary device, including a twisting spanner mechanism 1, the twisting spanner mechanism 1 includes a spanner sleeve 11, a spanner ring 12, a limiting column 13, a pushing plate 14, a reset compression spring 15, an external threaded sleeve 16, an end ring 17 and a wedge-shaped limiting end 18, the left end of the spanner sleeve 11 is integrally connected with the spanner ring 12, the spanner ring 12 is provided with a limiting through groove corresponding to the middle of the spanner sleeve 11, the limiting column 13 is inserted in the limiting through groove, and the limiting column 13 is located in the spanner ring 12 A wedge-shaped limiting end 18 is provided at one end, and a pushing disk 14 is fixedly connected to one end of the limiting column 13 located in the spanner sleeve 11. An external threaded sleeve 16 is threadedly connected to the inner side of the right end of the spanner sleeve 11, and an end ring 17 is integrally formed and connected to the outer peripheral side of the right end of the external threaded sleeve 16. A reset compression spring 15 is installed in the spanner sleeve 11, and the two ends of the reset compression spring 15 are respectively pressed against the end of the pushing disk 14 and the end of the external threaded sleeve 16. A healing cap screwdriver 4 is installed in the spanner ring 12, and a clamping plane is provided on one side of the wedge-shaped limiting end 18 and an inclined surface is provided on the other side; The healing cap screwdriver 4 includes a cylindrical tool seat 41, a twisting slot 42, a circular baffle 43, a boss 44 and a screwdriver rod 45. The top of the cylindrical tool seat 41 is fixedly connected to the circular baffle 43. The diameter of the cylindrical tool seat 41 is the same as the diameter of the inner circular groove of the wrench ring 12, and the diameter of the circular baffle 43 is larger than the diameter of the cylindrical tool seat 41. The top center of the circular baffle 43 is fixedly connected to the bottom end of the screwdriver rod 45 through the boss 44. The twisting slot 42 is provided in an annular array on the outer peripheral side of the cylindrical tool seat 41. The cylindrical tool holder 41 is installed in the circular groove inside the spanner ring 12. The circular baffle plate 43 can prevent the cylindrical tool holder 41 from falling down after being installed in the spanner ring 12, and can prevent the healing cap screwdriver 4 from detaching from the bottom of the spanner ring 12. The elastic force of the reset compression spring 15 allows the wedge-shaped limiting end 18 at the end of the limiting column 13 to be clamped with the torsion clamping groove 42. With the help of the spanner sleeve 11, the spanner ring 12 is rotated clockwise. The spanner ring 12 can drive the cylindrical tool holder 41 to rotate through the stable clamping plane of the wedge-shaped limiting end 18 and the torsion clamping groove 42, thereby driving the screwdriver rod 45 to rotate clockwise through the boss 44. The top of the screwdriver rod 45 is provided with The Pozidriv screwdriver head cooperates with the center of the end of the healing cap 7, so that the healing cap 7 can be screwed into and installed on the implant in the alveolar bone. With the help of the wrench sleeve 11, the wrench ring 12 is rotated counterclockwise, and the inclined surface of the wedge-shaped limit end 18 contacts the edge of the torsion groove 42. Due to the large friction at the connection between the implant and the healing cap 7, the inclined surface of the wedge-shaped limit end 18 and the edge of the torsion groove 42 slide against each other, allowing the wedge-shaped limit end 18 to overcome the elastic force of the reset compression spring 15 through the limit column 13 and retract into the limit groove. During this process, the cylindrical tool holder 41 does not rotate, and the reciprocating movement of the wrench sleeve 11 completes the insertion operation of the healing cap 7.

[0023] It also includes a twisting direction control mechanism 2, a torque limiting mechanism 3, a screwdriver anti-slip mechanism 5 and a healing cap anti-slip mechanism 6; One end of the twisting direction control mechanism 2 is connected to the middle of the right side of the push plate 14, and the other end of the twisting direction control mechanism 2 is connected to the end ring 17; The torque limiting mechanism 3 is installed at the right end of the wrench sleeve 11, and the torque limiting mechanism 3 is connected to the twisting direction control mechanism 2; The screwdriver anti-drop mechanism 5 is installed at one end of the wrench ring 12 close to the wrench sleeve 11; The screwdriver anti-slip mechanism 5 includes a detachable mounting assembly, a movable seat 53, a longitudinal rotation axis 54, a movable block 55, a torsion spring 56, a pressure rod 57 and a semicircular groove 58. The movable seat 53 is installed at one end of the wrench ring 12 close to the wrench socket 11 through a detachable mounting assembly. The movable seat 53 is movably connected to the movable block 55 through the longitudinal rotation axis 54. 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 semicircular groove 58. A torsion spring 56 is installed on the longitudinal rotation axis 54. The two ends of the torsion spring 56 are respectively connected to the movable seat 53 and the movable block 55. The torsion force of the torsion spring 56 allows the left end of the pressure rod 57 to move downward, so that the semicircular groove 58 on the pressure rod 57 cooperates with the bottom end of the screwdriver rod 45 in the healing cap screwdriver 4. The left end of the pressure rod 57 presses down on the boss 44 in the healing cap screwdriver 4 to prevent 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 preventing the wedge-shaped limit end 18 from detaching from the twisting slot 42 due to an incorrect twisting angle, thereby causing the healing cap screwdriver 4 to detach from the wrench ring 12, especially in the scenario where the Pozidriv screwdriver head of the healing cap screwdriver 4 is used downward.

[0024] The detachable mounting assembly includes a mounting groove 51 and a fastening bolt 52. Two mounting grooves 51 are respectively provided on the upper and lower sides of the middle part of one end of the wrench ring 12 close to the wrench sleeve 11.

The fastening bolt 52 is used to fix the movable seat 53 in the mounting groove 51. The movable seat 53 can be installed in one of the two mounting grooves 51 as needed to avoid occupying too much space when there are movable seats 53 in both mounting grooves 51.

[0025] The healing cap anti-drop mechanism 6 is installed on the wrench ring 12 .

[0026] The healing cap anti-detachment mechanism 6 includes a telescopic rod 64, a longitudinal support 65, a healing cap arc limiting rod 610, an arc limiting groove 611 at the bottom edge of the healing cap and a corresponding elastic component. The end of the wrench ring 12 close to the wrench sleeve 11 is detachably installed with two front and rear corresponding telescopic rods 64. The tops of the two telescopic rods 64 are respectively fixedly connected to the two ends of the longitudinal support 65. The longitudinal support 65 is connected to the right ends of the two healing cap arc limiting rods 610 through the corresponding elastic component. The inner sides of the two healing cap arc limiting rods 610 are arranged corresponding to each other, and the inner sides of the two healing cap arc limiting rods 610 are respectively provided with arc limiting grooves 611 at the bottom edge of the healing cap.

[0027] The healing cap anti-detachment mechanism 6 also includes a vertical through hole 61, a mounting bolt 62, and a mounting column 63. The wrench ring 12 is provided with two vertical through holes 61 on the front and rear sides of one end close to the wrench sleeve 11, and two mounting columns 63 are respectively inserted in the two vertical through holes 61. A locking screw hole is provided on the side of the wrench ring 12 corresponding to the middle of the vertical through hole 61. The locking screw hole is threadedly connected with a mounting bolt 62. The mounting bolt 62 is pressed 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 ring 12.

[0028] The mounting groove 51 is located between the two telescopic rods 64. The telescopic rods 64 and the longitudinal support 65 can be installed on the upper or lower side of the wrench ring 12 as needed. The telescopic rod 64 can be extended and retracted to allow the longitudinal support 65 to correspond to the bottom edge of the healing cap 7. The opposing elastic components allow the two healing cap arc limit rods 610 to approach each other. After the two healing cap arc limit rods 610 are approached, they are on the same circle. The two healing cap bottom edge arc limit grooves 611 correspond to the bottom edge of the healing cap 7. When the bottom center of the healing cap 7 is installed on the Pozidriv head of the healing cap screwdriver 4, the bottom edge of the healing cap 7 is in the two healing cap bottom edge arc limit grooves 611, which can prevent the healing cap 7 from falling off the Pozidriv head. At the same time, there is a gap between the healing cap bottom edge arc limit groove 611 and the bottom edge of the healing cap 7, which prevents the inner wall of the healing cap bottom edge arc limit groove 611 from having a large friction with the bottom edge of the healing cap 7.

[0029] The opposing elastic components include a longitudinal sliding groove 66, a longitudinal column 67, a limit compression spring 68 and a sliding control rod 69. Two longitudinal sliding grooves 66 are opened on the side 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 that are close to each other are slidingly connected to the sliding holes on the two sliding control rods 69 respectively, and the two sliding control rods 69 are slidingly connected to the two corresponding longitudinal sliding grooves 66 respectively. The left ends of the two sliding control rods 69 are fixedly connected to the right ends of the two healing cap arc limit rods 610 respectively, and the ends of the two longitudinal columns 67 that are away from each other are respectively sleeved with limit compression springs 68. The right ends of the two sliding control rods 69 extend to the outer sides of the right ends of the two longitudinal sliding grooves 66 respectively, which is convenient for controlling the use of the two sliding control rods 69. The elastic force of the two limit compression springs 68 pushes the two sliding control rods 69 to approach each other, so that the two healing cap arc limit rods 610 are close to each other. When the two healing cap arc limit rods 610 are at the closest distance, they are on the same circle. When the two healing cap arc limit rods 610 need to leave the bottom edge of the healing cap 7, the two sliding control rods 69 overcome the elastic force of the two limit compression springs 68 to separate, so that the two healing cap arc limit rods 610 are separated, and then the telescopic rod 64 is shortened, and the bottom edge of the healing cap 7 can leave the two healing cap bottom edge arc limit grooves 611.

[0030] When in use, the external threaded sleeve 16 can be twisted with the help of the end ring 17, so as to facilitate the disassembly and assembly of the external threaded sleeve 16, and the external threaded sleeve 16 is pressed against the reset compression spring 15, and the reset compression spring 15 pushes the limit column 13 to move left through the push plate 14, so that the wedge-shaped limit end 18 at the left end of the limit column 13 is extended into the wrench ring 12 and cooperates with the healing cap screwdriver 4, and the healing cap screwdriver 4 is installed in the wrench ring 12, the wedge-shaped limit end 18 is clamped with the healing cap screwdriver 4, and then the healing cap 7 is installed on the M-shaped screwdriver head at the top of the healing cap screwdriver 4, and then the top screw of the healing cap 7 is aligned with the screw hole of the implant in the alveolar bone, and the wrench ring 12 is turned clockwise with the help of the wrench sleeve 11, and the wrench ring 12 is passed. The clamping plane of the wedge-shaped limiting end 18 drives the healing cap screwdriver 4 and the healing cap 7 to rotate clockwise by a certain angle, and the healing cap 7 is screwed into the screw hole of the implant in the alveolar bone. Then, the wrench sleeve 11 is used to rotate the wrench ring 12 counterclockwise. The implant and the healing cap 7 are threadedly connected, so there is a large friction force. Therefore, the healing cap 7 and the healing cap screwdriver 4 will not rotate counterclockwise with the wrench ring 12. At the same time, the inclined surface of the wedge-shaped limiting end 18 allows the wedge-shaped limiting end 18 to overcome the elastic force of the reset compression spring 15 through the limiting column 13 and the pushing plate 14 and retract into the limiting groove. At this time, the healing cap screwdriver 4 does not rotate with the wrench ring 12 in the wrench ring 12. The wrench sleeve 11 is pulled back and forth to allow the healing cap screwdriver 4 to rotate counterclockwise. 4 is intermittently rotated clockwise, so that the healing cap screwdriver 4 drives the healing cap 7 to rotate intermittently clockwise, and the insertion operation of the healing cap 7 can be completed. With the help of the twisting direction control mechanism 2, the limiting column 13 and the wedge-shaped limiting end 18 are rotated 180 degrees, and the clamping plane and the inclined surface position on the wedge-shaped limiting end 18 are exchanged. At this time, the healing cap screwdriver 4 and the healing cap 7 can be driven to rotate counterclockwise by rotating the wrench ring 12 counterclockwise through the wrench sleeve 11, thereby loosening the healing cap 7, and the healing cap screwdriver 4 and the healing cap 7 will not rotate by rotating the wrench ring 12 clockwise with the help of the wrench sleeve 11. The healing cap 7 can be taken out by reciprocating the wrench sleeve 11. The setting of the torque limiting mechanism 3 can limit the insertion The torque of the healing cap 7, if the torque exceeds the limit value of the rotating healing cap 7, the wedge-shaped limit end 18 will retract into the limit 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 effect of the clamping plane of the wedge-shaped limit end 18 on the healing cap screwdriver 4 is stopped. At this point, it means that the healing cap 7 has been installed in place, and the setting of the screwdriver anti-detachment mechanism 5 avoids the use of the wrench sleeve 11 and the wrench ring 12 at a bad angle, which causes the healing cap screwdriver 4 to separate from the wrench ring 12. The healing cap anti-detachment mechanism 6 limits the bottom of the healing cap to prevent the healing cap from separating from the M-shaped screwdriver head on the top of the healing cap screwdriver 4, thereby ensuring that the healing cap screwdriver 4 or the healing cap will not fall off in the mouth.

[0031] For example 2, please refer to Figures 1 to 11, This embodiment provides a technical solution: a healing cap insertion and removal auxiliary device, this embodiment is a further explanation of the first embodiment; The twisting direction control mechanism 2 includes a control transverse axis 21, a transverse groove 22, a rotation control sleeve 23, a transverse slide bar 24, a control swivel 25, a friction protrusion 26, a control bolt 27 and a locking circular hole 28. The middle part of the right side of the push plate 14 is fixedly connected to the left end of the control transverse axis 21. The right end of the control transverse axis 21 passes through the center of the external threaded sleeve 16 and extends to the outside of the right end of the external threaded sleeve 16. A transverse groove 22 is provided on the outside of the right end of the control transverse axis 21. The right end of the control transverse axis 21 is slidably sleeved with the rotation control sleeve 23. The inner side of the dynamic control sleeve 23 is provided with a horizontal slide bar 24 which is slidably connected to the horizontal groove 22. The right end of the rotating control sleeve 23 is fixedly sleeved with a control swivel 25 on the outer side. The control swivel 25 is located on the right side of the end ring 17. The outer peripheral side of the control swivel 25 is provided with a friction protrusion 26 in an annular array. The edge of the control swivel 25 is threadedly connected with a transverse control bolt 27. The right end of the end ring 17 is provided with two locking circular holes 28 which are symmetrical about the center of the end ring 17, and the left end of the control bolt 27 extends into one of the locking circular holes 28. The control transverse axis 21 can move left and right along with the push plate 14 and the limit column 13. The rotation control sleeve 23 can slide left and right with the control transverse axis 21 through the horizontal slide bar 24 and the horizontal groove 22. The rotation control sleeve 23 can be driven to rotate by means of the friction protrusion 26, thereby driving the control transverse axis 21 and the limit column 13 to rotate. When the limit column 13 and the wedge-shaped limit end 18 need to be rotated 180 degrees to change the direction of the twisting force of the twisting wrench mechanism 1, the control bolt 27 is loosened to make the control bolt 27 leave the current locking circular hole 28, and then Then, the rotation control sleeve 23 is rotated 180 degrees through the friction protrusion 26, and the rotation control sleeve 23 drives the control horizontal axis 21, the limit column 13 and the wedge-shaped limit end 18 to rotate 180 degrees through the horizontal slide bar 24 and the horizontal groove 22, and then the control bolt 27 is tightened, and the control bolt 27 extends into another locking circular hole 28 to complete the locking of the rotation control sleeve 23, so that the control horizontal axis 21, the limit column 13 and the wedge-shaped limit end 18 are stabilized. At this time, the replacement of the position of the clamping plane and the inclined surface of the wedge-shaped limit end 18 is completed.

[0032] For example 3, please refer to Figures 1 to 11 , This embodiment provides a technical solution: a healing cap insertion and removal auxiliary device, this embodiment is a further explanation of the second embodiment; The torque limiting mechanism 3 includes an arc long plate 31, a limiting end cap 32, a pull ring 33, a movable shaft 1 35, a pulling rod 36, a movable shaft 2 37, a support 38, a rotating rod 39, a mounting frame 310, an end handle 311, an elastic resistance component and a torque limiting adjustment component. The upper and lower sides of the right end of the wrench sleeve 11 are respectively fixedly connected to the left ends of the two arc long plates 31, and the outer peripheral side of the right end of the control horizontal axis 21 is slidably sleeved with a pull ring 33, and the right end face of the control horizontal axis 21 is fixedly connected to the limiting end cap 32, and the upper and lower sides of the pull ring 33 are respectively connected by two movable Axis one 35 is movably connected to the left ends of the two pulling rods 36, and the right ends of the two pulling rods 36 are movably connected to the left ends of the rotating rod 39 through two movable shafts two 37 respectively. The right end of the rotating rod 39 is rotatably connected to the top of the pillar 38, and the bottom of the pillar 38 is fixedly connected to the arc long plate 31 on the lower side. The front and rear sides of the left end of the rotating rod 39 are respectively fixedly connected to the left ends of the two mounting frames 310, and the right ends of the two mounting frames 310 are fixedly connected to the left end of the end handle 311. The pull ring 33 is connected to the elastic resistance component, and the torque limiting adjustment component is installed on the elastic resistance component.

[0033] When in use, hold the end handle 311 and rotate it clockwise. The end handle 311 can drive the rotating rod 39 to rotate relative to the pillar 38 through the mounting bracket 310. The rotating rod 39 pulls the pull ring 33 to the right through the pulling rod 36. Due to the existence of the limiting end cap 32, the pull ring 33 and the control horizontal axis 21 will not be separated. When the pulling force of the pulling rod 36 on the pull ring 33 is sufficient to overcome the resistance of the elastic resistance component and the reset compression spring 15, the pull ring 33 pulls the control horizontal axis 21 to the right with the help of the limiting end cap 32. The control horizontal axis 21 can pull the limiting column 13 and the wedge-shaped limiting end head 18 to the right, and finally the wedge-shaped limiting end head 18 will be retracted into the limiting through groove. At this time, the clamping plane originally acting on the healing cap screwdriver 4 will be separated from the healing cap screwdriver 4, and the healing cap screwdriver 4 cannot be twisted any further by turning the wrench ring 12 clockwise. The torque limiting adjustment component can change the resistance of the elastic resistance component. If the torque is too large, the healing cap screwdriver 4 and the healing cap 7 cannot be twisted further. As a protective measure, the healing cap screwdriver 4 and the healing cap 7 are prevented from being damaged by excessive torque, and the healing cap 7 or the implant is also prevented from being damaged. The alveolar bone of the implant recipient can also be avoided. It should be noted that the torque limiting mechanism 3 is mainly used in the final stage of the insertion process of the healing cap 7 to limit the maximum torque applied. In the initial stage of the insertion of the healing cap 7, the wrench sleeve 11 is generally turned instead of the end handle 311. This can avoid the friction between the pull ring 33 and the control horizontal axis 21 when the end handle 311 is turned counterclockwise, which affects the smooth retraction of the limit column 13 and the wedge-shaped limit end 18 into the limit groove. When the wrench sleeve 11 and the wrench ring 12 are turned counterclockwise, the limit column 13, the wedge-shaped limit end 18 and the control horizontal axis 21 move to the right. At this time, the limit end cap 32 also moves to the right, and the limit end cap 32 has a movable space between the pull ring 33 and the rotating rod 39.

[0034] 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.

[0035] 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.
