Description

Technical Field

[0001] The present invention relates to the technical field of oral dental implants, and particularly to an intra - maxillary sinus lifting device and a lifting method thereof, which are specifically used for oral dental implants. Background Art

[0002] At present, there are many tools and methods for intra - maxillary sinus lifting (i.e., alveolar ridge crest approach) at home and abroad. Ultimately, they can be divided into two categories: one is the impact - type intra - maxillary sinus lifting. In this surgical method, a cavity is first prepared and about 1 mm of bone mass at the sinus floor is reserved. Then, the bone mass at the maxillary sinus floor is knocked and lifted to achieve the purpose of lifting. The other is the non - impact - type intra - maxillary sinus lifting. In this surgical method, there is no need for knocking. Instead, through various tools and methods, either the maxillary sinus floor mucosa is directly lifted, or the maxillary sinus floor mucosa is first peeled off and then lifted to achieve the purpose of lifting.

[0003] Due to the need for knocking, the impact - type method is likely to cause discomfort to patients during and after the operation, and even cause complications such as otolithiasis. Although the non - impact - type method does not require knocking and is not likely to cause discomfort to patients, the lifting height that can be achieved by all current non - impact - type intra - maxillary sinus lifting tools and methods is relatively limited. For the situation where the remaining alveolar bone height in the posterior maxillary region is less than 3 mm or 4 mm, the current intra - maxillary sinus lifting methods are more likely to cause rupture of the maxillary sinus floor mucosa and still cannot achieve an ideal lifting effect. This is also the bottleneck and pain point of the current intra - maxillary sinus lifting surgery. Summary of the Invention

At this time, the liquid level rises as the rotary body rises, so as to lift the maxillary sinus floor mucosa by a height of 1-2 mm through hydraulic pressure;

[0032] S6. Rotate out the rotary mounting seat and the rotary lifter of the implant cavity, adjust the locking member to open the water passage, and drain the normal saline remaining in the rotary lifter;

[0033] S7. Select a rotary lifter with the initial height of the rotary body, assemble it with the rotary mounting seat and the stop ring, and then assemble the rotary mounting seat, the implant rotating device and the rotary connecting member; then start the implant rotating device, and use the implant rotating device to drive the rotary lifter to rotate into the implant cavity; when the top of the rotary body exceeds the edge of the maxillary sinus floor by 2 mm, the implant rotating device stops working, and the implant rotating device and the rotary connecting member are disassembled;

Clamp the lower end of the rotary mounting seat with the shaking forceps in cooperation, use the position near the edge of the maxillary sinus floor of the implant cavity as a fulcrum, and rotate slowly and obliquely 360° around the maxillary sinus floor to achieve the effect of lifting and peeling the maxillary sinus floor mucosa in all directions at the edge of the maxillary sinus floor; until the maxillary sinus floor mucosa is lifted to a height of 3 mm, remove the shaking forceps, and rotate out the rotary mounting seat and the rotary lifter of the implant cavity;

[0035] S9. Select a rotary lifter with the height of the rotary body being 5 mm, assemble it with the rotary mounting seat and the stop ring, and then assemble the rotary mounting seat, the implant rotating device and the rotary connecting member; then start the implant rotating device, and use the implant rotating device to drive the rotary lifter to rotate into the implant cavity; when the top of the rotary body exceeds the edge of the maxillary sinus floor by 3 mm, the implant rotating device stops working, and the implant rotating device and the rotary connecting member are disassembled;

[0040] Compared with the existing technology, the present invention has the following advantages:

[0041] The present invention combines a rotating mounting base, a rotating lifter, a water channel, a water outlet hole, and a locking member, and adopts a hydraulic lifting method. First, rotate the rotating mounting base to cause the rotating lifter to rotate, squeeze into the implant socket and approach the maxillary sinus floor that has been pre-penetrated through the sinus floor bone but not through the sinus floor mucosa. Then, when injecting liquid into the closed space between the maxillary sinus floor mucosa and the top of the rotating lifter, by adjusting the locking member, the liquid can be confined in the closed space without backflow. Then, rotate the rotating mounting base again to cause the rotating lifter to rotate, and the liquid rises as the height of the top of the lifter increases, thereby achieving a preliminary lifting effect. At this time, by adjusting the locking member again, the liquid between the lifter and the maxillary sinus floor mucosa is drained out, and the lifter is continuously rotated to raise its top to the height of the above hydraulic lifting. Finally, use a rocking forceps to clamp the rotating mounting base and perform a 360°, inclined, and slow rotation to achieve the effect of lifting and peeling the maxillary sinus floor mucosa in all directions at the edge of the maxillary sinus floor. At this time, the minute lift at each angle in 360° is finally accumulated to obtain a relatively large total lift height. Therefore, it can avoid the discomfort of patients caused by the impact lifting method for maxillary sinus internal lifting, and can also change the limitations of the non-impact lifting method for maxillary sinus internal lifting. Through an innovative hydraulic lifting method and the method of accumulating minute lift heights in all directions, the maxillary sinus floor mucosa is lifted to achieve a good lifting effect. Especially for the situation where the remaining alveolar bone height in the posterior maxillary tooth area is <3 mm or 4 mm, the ideal lifting effect can be achieved by using this tool and method, and it is safer and the operation method is simple.

Specific embodiments

[0051] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0052] As Figures 1 to 6 shown, a maxillary sinus internal lifting device for oral dental implants includes a rotary mounting base 1, a rotary elevator 2, a water channel 3, a water outlet hole 4, a locking part 5 and a swaying pliers 6. Among them, the lower end of the rotary elevator 2 is connected to the top end of the rotary mounting base 1; the water channel 3 is located inside the rotary mounting base 1 and the rotary elevator 2 and is arranged from the bottom end of the rotary mounting base 1 to the top end of the rotary elevator 2; the water outlet hole 4 is arranged at the top of the rotary elevator 2 and is communicated with the water channel 3; the locking part 5 is arranged on the rotary mounting base 1 and is used to open or lock and close the water channel 3;; the swaying pliers 6 cooperate with the rotary mounting base 1 to clamp the rotary mounting base.

[0053] The maxillary sinus internal lifting device for dental implants is combined with a rotating mounting base 1, a rotating lifter 2, a water passage 3, a water outlet hole 4 and a locking member 5. By using the hydraulic lifting method, first rotate the rotating mounting base 1 to make the rotating lifter 2 rotate, and extrude it into the dental implant socket 30 near the maxillary sinus floor where the sinus floor bone has been perforated in advance but the sinus floor mucosa has not been perforated. Then, when injecting liquid into the closed space between the maxillary sinus floor mucosa 40 and the top of the rotating lifter 2, the liquid can be confined in the closed space without backflow by adjusting the locking member 5. Then, rotate the rotating mounting base 1 again to make the rotating lifter 2 rotate, and the liquid (such as normal saline) rises as the top height of the rotating lifter 2 increases, so as to achieve a preliminary lifting effect. At this time, by adjusting the locking member 5, the liquid between the lifter 2 and the maxillary sinus floor mucosa is drained out, and the lifter 2 is continuously rotated to raise its top to the mucosa height of the above hydraulic lifting. Finally, use the shaking forceps 6 to clamp the rotating mounting base 1 and perform a 360°, inclined and slow rotation to achieve the effect of being lifted and peeled off in all directions at the edge of the maxillary sinus floor. At this time, the minute lift at each angle in 360° is finally accumulated to obtain a relatively large total lift height. Thus, it can avoid the discomfort of patients caused by the punching type maxillary sinus internal lifting method, and can also change the limitations of the non-punching type maxillary sinus internal lifting method. Through the innovative hydraulic lifting method and the method of accumulating the minute lift heights in all directions, the maxillary sinus floor mucosa 40 is lifted to achieve a good lifting effect. Especially for the situation where the height of the residual alveolar bone 20 in the posterior maxillary tooth area is less than 3 mm or 4 mm, the ideal lifting effect can be achieved by using this tool and method, and it is safer and the operation method is simple. Specifically, the water passage 3 includes a first water passage 31 and a second water passage 32. The first water passage 31 extends from the bottom end to the top end of the rotating mounting base 1; the second water passage 32 extends from the bottom end to the top end of the rotating lifter 2 and is connected to the first water passage 31; the rotating lifter 2 includes a lifting scale rod 21 and a rotating body 22. Among them, the lower end of the lifting scale rod 21 is connected to the rotating mounting base 1. A scale ruler 211 is provided on the outer peripheral side of the lifting scale rod 21 in the up and down direction, that is, the lower end of the scale ruler 211 is provided at the lower end of the outer peripheral side of the lifting scale rod 21, and the upper end of the scale ruler 211 extends along the upper end of the outer peripheral side of the lifting scale rod 21. The graduation value of this scale is 1 mm, which is convenient to clearly know the rising distance of the rotating lifter 2.The rotating body 22 is connected to the upper end of the lifting scale rod 21; the water outlet hole 4 is arranged on the top of the rotating body 22; the second water channel 32 includes an upper water channel 3213 and a lower water channel 3223; the lower water channel 3223 is arranged in the lifting scale rod 21; the lower end of the lower water channel 3223 is communicated with the upper end of the first water channel 31; the upper water channel 3213 is arranged in the rotating body 22 and is communicated with the upper end of the lower water channel 3223 and is communicated with the water outlet hole 4. By dividing the water channel 3 into the first water channel 31 and the second water channel 32, which are respectively arranged in the rotating mounting seat 1 and the rotating lifter 2, and for the rotating body 22 and the lifting scale rod 21, dividing the second water channel 32 into the upper water channel 3213 and the lower water channel 3223, it is convenient for the liquid to enter from the first water channel 31, pass through the lower water channel 3223 and the upper water channel 3213, and then flow out from the water outlet hole 4, and then combine with the locking member 5 to confine the liquid in the closed space without backflow, which helps to hydraulically lift and jack up the maxillary sinus floor mucosa 40 in the subsequent steps to achieve a good lifting effect.

[0054] Preferably, the rotating body 22 includes a rotating spherical body 221 and a rotating cylinder 222; the rotating cylinder 222 is located between the lower end of the rotating spherical body and the upper end of the lifting scale rod 21; the water outlet hole 4 is arranged on the rotating spherical body 221; the upper water channel 3213 is located in the rotating cylinder 222. By forming the rotating body 22 by arranging the rotating spherical body 221 on the rotating cylinder 222, the top of the rotating body 22 is smooth and blunt, reducing the pressure on the maxillary sinus floor mucosa 40 and not easily piercing the maxillary sinus floor mucosa 40.

[0055] And the lifting scale rod 21 is a cylindrical rod; the diameter of the rotating cylinder 222 is larger than the diameter of the lifting scale rod 21. By setting the diameter relationship between the lifting scale rod 21 and the rotating cylinder 222 like this, when the rotating body 22 is stuck at the maxillary sinus floor edge near the maxillary sinus side of the implant cavity 30, it can rotate stably and slowly within a controllable range of 360° inclination with the maxillary sinus floor edge as the center in the implant cavity 30, achieving the effect of jacking up and peeling the maxillary sinus floor mucosa 40 in all directions at the maxillary sinus floor edge, so that the rotating body 22 accumulates the tiny lifting heights in all directions to obtain a relatively large total lifting height, reducing the mucosal tension when directly jacking up the same total lifting height from the center of the sinus floor mucosa and reducing the penetration rate of the mucosa to achieve a better lifting effect.

[0056] Preferably, a spiral thread 2221 extending in the up-and-down direction of the rotating cylinder 222 is provided on the outer peripheral side of the rotating cylinder 222. By providing the spiral thread 2221 on the outer peripheral side of the rotating cylinder 222, the rotating body 22 is guided to smoothly rotate into the implant socket 30, which is more conducive to the rotating body 22 squeezing the implant socket 30 to form a closed space, and then realizing the hydraulic lifting of the maxillary sinus floor mucosa 40.

[0057] In this specific embodiment, the rotary mounting seat 1 includes a swaying base 11, a clamping groove portion 12 and a swaying connecting portion 13; the clamping groove portion 12 is connected between the swaying base 11 and the swaying connecting portion 13; the rotary lifter 2 is connected to the top end of the swaying connecting portion 13; specifically, an insertion groove matching with the lower end of the rotary lifter 2 is provided on the swaying connecting portion 13, and the lower end of the rotary lifter 2 is fittingly inserted into the insertion groove. The first water passage 31 is arranged from the bottom end of the swaying base 11 to the top end of the swaying connecting portion 13 and is communicated with the second water passage 32.

[0058] The locking member 5 is a screwing bolt; the rotary mounting seat 1 has a locking screw hole 112 matching with the screwing bolt and passing through the water passage 3; specifically, the locking screw hole 112 is provided at the upper end of the swaying base 11; the screwing bolt is fittingly screwed into or out of the locking screw hole 112 to open or lock the water passage 3. Specifically, the diameter of the screwing bolt is larger than the diameter of the water passage 3, which helps to open or lock the water passage 3. By screwing the screwing bolt into or out of the locking screw hole 112, it helps to open or lock the water passage 3, and further helps to realize the hydraulic lifting of the maxillary sinus floor mucosa 40.

[0059] Wherein, the maxillary sinus internal lifting device for dental implants further includes a stop ring 8, a planting rotating device 9 and a rotating connecting member 10; the stop ring 8 is sleeved on the rotary lifter 2 and is fittingly clamped on the upper end of the rotary mounting seat 1; that is, the stop ring 8 is specifically clamped on the swaying connecting portion 13 to play a good limiting role; a clamping groove 111 matching with the upper end of the rotating connecting member 10 and detachably connected and communicated with the water passage 3 is provided at the bottom end of the rotary mounting seat 1; the lower end of the rotating connecting member 10 is connected to the planting rotating device 9. Before hydraulic lifting, first install and clamp the stop ring 8 on the swaying connecting portion 13, then fit and connect the upper end of the rotating connecting member 10 with the clamping groove 111, and the lower end of the rotating connecting member 10 is detachably connected to the planting rotating device 9. The planting rotating device 9 is used to drive the rotating connecting member 10 to rotate, and then drive the rotary mounting seat 1 and the rotary lifter 2 to rotate synchronously, which is convenient for the rotary lifter 2 to lift towards the maxillary sinus floor mucosa 40 in the implant socket 30, and further helps to realize the hydraulic lifting of the maxillary sinus floor mucosa 40 in the subsequent steps.

[0060] In this specific embodiment, the maxillary sinus internal lifting device for dental implants further includes a water injection pipe 7 which is sleeved in cooperation with the lower end of the rotary mounting base 1 and is communicated with the lower end of the water channel 3. By arranging the water injection pipe 7 to be sleeved in cooperation with the lower end of the rotary mounting base 1, specifically in cooperation with the shaking base 11, the connection between the water injection pipe 7 and the water channel 3 is completed. Liquid, such as physiological saline, is passed through the water injection pipe 7 into the water channel 3, so that the liquid is injected into the closed space between the maxillary sinus floor mucosa 40 and the top of the rotary lifter 2. Then, by adjusting the locking member 5, the liquid is confined in the closed space without backflow. Then, the rotary mounting base 1 is rotated so that the rotary lifter 2 is slowly screwed in until its top is flush with the edge of the maxillary sinus floor. At this time, the liquid (such as physiological saline) rises as the top height of the rotary lifter 2 rises, thereby lifting the maxillary sinus floor mucosa 40. This can avoid the discomfort of the patient caused by the punching type maxillary sinus internal lifting method and can also change the limitations of the non-punching type maxillary sinus internal lifting method. Through innovative hydraulic lifting and accumulating the tiny lifting heights in each direction, a good lifting effect can be achieved.

[0061] In order to achieve the effect of jacking up and peeling the maxillary sinus floor mucosa 40 in all directions at the edge of the maxillary sinus floor safely and effectively, the rocking forceps 6 includes a left half forceps 61 and a right half forceps 62 hinged to the left half forceps 61; the left half forceps 61 has a left clamping part 611; the right half forceps 62 has a right clamping part 621; the upper ends of the left clamping part 611 and the right clamping part 621 respectively have a left clamping beak 6111 and a right clamping beak 6211; when the left half forceps 61 and the right half forceps 62 are closed, the left clamping part 611 and the right clamping part 621 cooperate to clamp the rocking base 11, and the left clamping beak 6111 and the right clamping beak 6211 are clamped into the clamping groove part 12. By closing the left half forceps 61 and the right half forceps 62, the left clamping part 611 and the right clamping part 621 cooperate to clamp the rocking base 11 and the left clamping beak 6111 and the right clamping beak 6211 are clamped into the clamping groove part 12, clamping and fixing the rotary mounting seat 1 on the rocking forceps 6, with a simple structure and stable connection. When the rotating body 22 rises to the height of the maxillary sinus floor mucosa reached by hydraulic lifting and is stuck at the cortical bone at the edge of the maxillary sinus floor near the maxillary sinus side of the implant socket 30, with the edge of the maxillary sinus floor as the fulcrum and the maxillary sinus floor as the center, the rocking forceps 6 is rocked steadily and slowly in a 360° tilt within a controllable range, so that the rotary mounting seat 1 and the rotary lifter 2 rotate in a 360° tilt within a controllable range, achieving the effect of jacking up and peeling the maxillary sinus floor mucosa 40 in all directions at the edge of the maxillary sinus floor, so that the rotating body 22 accumulates the tiny lifting heights in all directions to obtain a relatively large total lifting height, reducing the mucosal tension when directly jacking up the same total lifting height from the center of the maxillary sinus floor mucosa 40, reducing the penetration rate of the maxillary sinus floor mucosa 40, and achieving a better lifting effect.
