The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Referring to fig. 1 to 3, an embodiment of the present invention provides a removal tool 10 and a removal assembly 100 comprising a wrench 20, a holder 30 and the removal tool 10, adapted to remove an abutment 200 of a dental implant system from an implant 300 of the dental implant system.
Specifically, referring to fig. 1 and 2, the extraction tool 10 includes a support rod 11 and a sleeve 12.
The support rod 11 is a one-piece member, and has a substantially long straight rod structure with a central axis V1, and the central axis V1 defines the vertical direction, and the support rod 11 includes a vertically extending long screw 111 and a wrench engaging portion 112 connected to the upper end of the screw 111.
Wherein the outer wall of the screw 111 has an external thread; the wrench mating portion 112, as the name implies, can be mated with the wrench 20 to form an area of the support rod 11 that receives external torque, such as from the wrench 20.
The sleeve 12 is also an integrally formed member having a generally cylindrical configuration with a central axis V2. The sleeve 12 includes a grip portion 122, an internal thread formed on an inner wall thereof, and an elastic portion 121 at a lower end thereof.
The holding portion 122, as the name implies, can cooperate with the holder 30 to form a region where the sleeve 12 receives an external holding force from the holder 30; the elastic member 121 has an elastic deformation capability in the free form, and can recover its free form due to the loss of the external force in the deformed form.
The support rod 11 and the sleeve 12 have an exploded state as shown in fig. 2 and an assembled state as shown in fig. 1.
In the disassembled state, the support rod 11 and the sleeve 12 are separated from each other without being engaged, and the elastic portion 121 is elastically deformed radially inward by an external force from its free form toward the central axis V2 of the sleeve 12.
In the assembled state, the sleeve 12 is sleeved outside the screw 11, and at this time, the central axis V2 of the sleeve 12 and the central axis V1 of the screw 11 are both coincident and located on the central axis V of the extraction tool 10; in the assembled state, the lower end 1110 of the screw 111 extends out of the lower side of the socket 12, and the wrench engaging portion 112 is exposed above the socket 12, so that the screw 111 can rotate around the central axis V relative to the socket 12 by the wrench engaging portion 112, and the external thread and the internal thread are engaged with each other, so that the screw 111 can move downward along the central axis V while rotating relative to the socket, and the lower end 1110 of the screw 111 is further away from the socket 12 downward.
The tool 10 is further described in connection with fig. 3 through a process of use.
In the operation in which the abutment 200 is removed from the implant 300:
first, the sleeve 12 and the support rod 11 are maintained in the disassembled state, in this case, the holder 30 or other auxiliary tool is used to insert the lower end of the sleeve 12 into the cavity of the abutment 200 from the top to the bottom, and during the insertion process, the elastic part 121 is pressed by the wall surface of the cavity of the abutment 200 and is forced to be elastically deformed radially inward from its free form toward the central axis V2 of the sleeve 12;
when the elastic part 121 loses the pressing force from the inner cavity wall surface of the base 200 along with the downward movement of the elastic part 121, the elastic part 121 can recover at least partial deformation and be clamped below the lower end surface of the base 200;
then, the supporting rod 11 is inserted into the sleeve 12 from top to bottom, the holder 30 is coupled to the holding portion 122 to fix the sleeve 12, the holding portion 122 prevents the sleeve 12 from rotating around the central axis V, meanwhile, the wrench 20 is coupled to the wrench coupling portion 112, and the wrench coupling portion 112 drives the supporting rod 11 to rotate around the central axis V, and as the supporting rod 11 rotates, the external thread and the internal thread are screwed together to make the screw 111 move downward along the central axis V relative to the sleeve 12; after the lower end 1110 of the screw 111 abuts against the implant 300, the support rod 11 continues to rotate, so as to generate an upward reaction force, and drive the sleeve 12 to lift the abutment 200 upward through the elastic part 121, thereby separating the abutment 200 from the implant 300.
As can be seen from the above description, in the embodiment, the elastic part 121 is arranged, and the sleeve 12 is in threaded fit with the support rod 11, so that the support rod 11 is pressed against the implant 300 downward, and the sleeve 12 lifts the abutment 200 upward, so that the lifting force on the abutment 200 is limited between the abutment 200 and the implant 300, the lifting force between the implant 300 and the human tissue is not caused to damage the connection strength between the implant 300 and the human tissue, and the implant 300 is not required to shake as in the prior art to be damaged, thereby avoiding the injury to the patient; moreover, after the abutment 200 is removed, the elastic part 121 can fix the abutment 200 from the lower end surface of the abutment 200, so as to prevent broken fragments of the abutment 200 from falling down, and avoid medical accidents caused by the abutment 200 falling into the oral cavity of a patient; in addition, when the elastic part 121 is inserted into the cavity of the abutment 200, the elastic part 121 is deformed again, so that a remarkable sound prompt and a positioning feeling are generated, and a doctor can accurately grasp the operation success rate of the operation.
Further, the elastic portion 121 includes a resilient piece 1211 extending downward and a boss 1212 located at a lower end of the resilient piece 1211, wherein the boss 1212 protrudes outward from the resilient piece 1211. Thereby, in the process of inserting the lower end portion of the sleeve 12 into the cavity of the abutment 200, the boss 1212 receives a pressing force from the wall surface of the cavity of the abutment 200, and the elastic portion 121 is elastically deformed inward; when the boss 1212 moves to the lower side of the base 200, the boss 1212 is no longer pressed by the inner cavity wall surface of the base 200, the elastic portion 121 can recover at least part of the deformation, and the boss 1212 is clamped under the lower end surface of the base 200.
Preferably, in the free form of the elastic portion 121, the upper end surface of the boss 1212 is a plane perpendicular to the central axis V2 of the sleeve 12, or may be an inclined surface inclined downward from the outside to the inside. Thus, the abutment firmness of the boss 1212 against the abutment 300 can be ensured, and the abutment 300 is prevented from being accidentally disengaged when being lifted upwards.
Further preferably, the sleeve 12 has at least two elastic parts 121, and at least two elastic parts 121 are arranged at intervals, for example, in the example of the drawings, a gap 1210 is formed between two adjacent elastic parts 121; in addition, at least two of the elastic portions 121 are evenly distributed around the central axis V2 of the sleeve 12.
In the present embodiment, the sleeve 12 has four elastic portions 121, and the four elastic portions 121 are equally divided around one circumference of the central axis V2.
Further, in the assembled state, the inner side wall of the elastic part 121 contacts the outer wall of the screw 111, so that the elastic part 121 is prevented from being elastically deformed radially inward under the abutting of the screw 111, so that the boss 1212 of the elastic part 121 can be firmly clamped at the lower end surface of the abutment 300, and the boss 1212 and the abutment 300 are prevented from being accidentally disengaged due to the inward deformation of the elastic part 121 when the abutment 300 is pulled upward.
In the present embodiment, the inner sidewalls of the four elastic parts 121 substantially enclose a cylindrical cavity, and the cylindrical cavity takes the central axis V2 as an axis.
The screw 111 includes an upper rod portion 1111, a middle rod portion 1112 and a lower rod portion 1113 which are sequentially arranged from top to bottom, and the upper rod portion 1111, the middle rod portion 1112 and the lower rod portion 1113 are respectively cylindrical with an upper diameter and a lower diameter, and the diameters of the three are sequentially reduced.
In this embodiment, in the assembled state, the four elastic parts 121 are wrapped around the outside of the lower rod part 1113, and at this time, all of the four elastic parts 121 are in a free form without elastic deformation, and the inner side walls of the four elastic parts 121 just contact the outer wall of the lower rod part 1113, so that the lower rod part 1113 can prevent the elastic parts 121 from elastically deforming inward toward the central axis V2 of the sleeve 12.
The external thread may be formed on the outer wall of any one of the upper rod portion 1111, the middle rod portion 1112 and the lower rod portion 1113, or may be formed on the outer wall of two or even three of them. The position of the internal thread on the inner wall of the sleeve 12 can be matched with the external thread.
Further, the outer wall of the holding portion 122 is polygonal, such as oval, quadrilateral, hexagonal, octagonal, and the like, and correspondingly, the holder 30 may be an open wrench or other holding tools available in the art, so as to fix the sleeve 12 in the circumferential direction of the central shaft V2 by engaging with the holding portion 122, thereby preventing the sleeve 12 from rotating synchronously and in the same direction with the supporting rod 11.
Preferably, the sleeve 12 further includes a retaining boss 123 connected to the upper end of the holding portion 122, and in detail, the lower end of the outer wall of the retaining boss 123 is connected to the upper end of the outer wall of the holding portion 122 inwards, so that when the holder 30 is fitted to the holding portion 122, the holder 30 can be abutted under the retaining boss 123, thereby preventing the sleeve 12 from falling off the holder 30 accidentally during the operation, and further preventing the occurrence of medical accidents.
Further, the outer wall of the wrench mating portion 112 is also polygonal, such as oval, quadrilateral, hexagonal, octagonal, and so on, and correspondingly, the wrench 20 may be a ratchet wrench or other suitable wrench in the art adapted to the wrench mating portion 112, so as to drive the support rod 11 to rotate around the central axis V1 by applying a torque force through the wrench mating portion 112.
Further preferably, the removing tool further includes an O-ring 13, and the O-ring 13 is embedded in an annular groove 1120 of an outer wall of the wrench mating part 112, wherein the annular groove 1120 is located at an axial middle portion of the wrench mating part 112. Thereby, the support rod 11 can be clamped in the wrench 20 by the deformation of the O-ring 13.
To sum up, compare with prior art, the beneficial effect of this embodiment lies in: when the support rod 11 supports the implant 300 downwards, the sleeve 12 lifts the base 200 upwards by using the reaction force generated by screwing the threads, the lifting force is limited between the base 200 and the implant 300, the connection strength between the implant 300 and the human tissue is not damaged by the lifting force between the implant 300 and the human tissue, and the implant 300 is not damaged by shaking as in the prior art, so that the injury to the patient is avoided; moreover, after the abutment 200 is removed, the elastic part 121 can fix the abutment 200 from the lower end surface of the abutment 200, so as to prevent broken fragments of the abutment 200 from falling down, and avoid medical accidents caused by the abutment 200 falling into the oral cavity of a patient; in addition, the elastic part 121 generates obvious sound prompt and positioning sense during the process of inserting into the cavity of the base 200, so that the doctor can accurately grasp the operation success rate of the operation.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
