Description

Technical Field

[0001] The present invention relates to the field of oral implant equipment, and more particularly to a bone powder filler for oral implant surgery. Background Art

[0002] Oral implant is a kind of oral prosthesis that uses artificial implants implanted in the jawbone to support the denture, which can reduce or eliminate the need for a base, making the patient feel more comfortable. Oral implant requires filling bone powder at the root of the tooth or on the severely atrophied alveolar bone to improve the stability of the denture implant and increase the chewing power of the teeth.

[0003] For patients with severe alveolar bone atrophy, the implant needs to be fixed on the alveolar bone. However, due to different patient conditions, the depth of the alveolar bone after atrophy in some patients is not enough, and there will be an exposed cavity around the implant. At this time, it is necessary to fill the prepared bone powder inside to ensure the stability of the implant after implantation. At present, bone powder is usually filled with a bone spoon and a bone rod. The bone spoon is used to support the bone powder, and the bone rod is used to push the bone powder in the bone spoon into the cavity.

[0004] The above operation of using the bone stick and the bone spoon together has the following defects in practical application:

[0005] 1. Since the bone stick and the bone spoon are both manually controlled, the medical staff must use both hands to operate them at the same time. At the same time, the amount of bone powder filled cannot be effectively controlled. The bone stick may shake too much, causing the bone powder to spill or even knock over the bone spoon, which places high demands on the operation of the medical staff.

[0006] 2. Bone powder filled in the natural state alone cannot effectively achieve dense filling between bone powders, resulting in insufficient tightness between the implant and the implant, which can easily affect the strength of the implant. Summary of the invention

[0007] In view of the problem in the prior art that the filling amount of bone powder and the density after filling cannot be more effectively controlled, the purpose of the present invention is to provide a bone powder filler for oral implant surgery.

[0008] To solve the above problems, the present invention adopts the following technical solutions:

[0017] In a natural state, the bottom of the transmission arm is in a state of resisting against the outer wall of the filling cylinder under the action of the torsion spring.

[0018] Optionally, a convex ball is fixed to the bottom of the bottom of the transmission arm, and a transmission rope is connected to the top;

[0019] A limiting bolt for limiting the position of the support seat is threadedly penetrated on the support ring.

[0020] Optionally, the transmission element includes a shell fixed to the top of the filling cylinder, a sliding plate slidably arranged on the inner wall of the shell, and a supporting spring arranged on the sliding plate and connected to the top wall of the shell;

[0021] Wherein, the bottom wall of the sliding plate is connected with a transmission rod, and one end of a plurality of the transmission rods extends to the outside of the shell and is commonly connected with a rotating ring.

[0022] Optionally, the bottom wall of the rotating ring is movably connected to a transmission ring for connecting the transmission rope;

[0023] The rotating ring is fixedly sleeved on the outer wall of the filling cylinder.

[0024] Optionally, the drive element comprises a drive rope disposed within the handle;

[0025] One end of the drive rope extends inside the shell and is fixed to the center of the sliding plate, and the other end is also connected to a toggle block, which is slidably assembled inside the handle. Toggling the toggle block can make it slide along the length direction of the handle to form a tensioning drive for the drive rope.

[0026] Optionally, the material control element comprises an upper material control plate installed in the material discharge port and a lower material control plate arranged close to the upper material control plate;

[0027] Wherein, a guide funnel is fixed on the outer side of the lower material control plate, an inclined rod is fixed on one side of the top of the guide funnel, a connecting slider is fixed on one end of the inclined rod, and the connecting slider is slidably arranged in the annular groove and fixed to the support seat;

[0028] The surfaces of the upper material control plate and the lower material control plate are both provided with corresponding material discharge grooves, and the vibrating extrusion element is rotated so that the inclined rod drives the lower material control plate to rotate relative to the upper material control plate.

[0029] Optionally, the auxiliary expansion element includes a support body and tooth support areas formed at both ends of the support body;

[0030] The support body is provided with a strip groove and an adjustment groove on one side relative to the filling cylinder;

[0031] There are a plurality of adjustment grooves which are distributed perpendicularly to the strip grooves. The plurality of adjustment grooves are arranged on the support body at equal intervals and are connected to the strip grooves.

[0032] Optionally, the connecting member includes a connecting column, a universal ball fixedly connected to the end of the connecting column, and a ball seat movably wrapped around the surface of the universal ball;

[0033] Wherein, the connecting column is fixedly connected to the housing, and the ball seat is slidably arranged in the adjustment groove;

[0034] An anti-skid protrusion is fixed on the ball seat, and a matching groove matching with the anti-skid protrusion is arranged in the adjustment groove.

[0035] Optionally, a feeding pipe is also connected to the surface of the filling cylinder.

[0036] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0037] In the above scheme, by setting the vibrating extrusion element on one side of the filling cylinder, the bone powder can be manually knocked to orderly fall into the filling cylinder during the bone powder filling, thus avoiding the situation that the bone powder is difficult to control or even spilled;

[0038] In combination with the setting of auxiliary structural elements, the patient's oral cavity and the device can be effectively supported synchronously, which not only avoids the influence of the upper and lower gums on the bone powder filling, but also forms a support for the filling tube, so that the filling can be performed with one hand, and the stability during the filling process is further guaranteed.

[0039] By adjusting the vibrating extrusion element to form an extrusion state, the convex ball on the transmission arm can be manually controlled to form a resistance and slapping on the patient's implanted gums, which can not only promote the dense filling of the bone powder and the gap by vibrating the gums, but also squeeze the bone powder above to promote the compaction of the internal bone powder. At this time, in conjunction with the role of the auxiliary support element, it can also form support for the filling cylinder, thereby achieving effective leverage on the transmission arm to meet the resistance of the convex ball bone powder.

[0040] By means of the material control element, when the vibrating extrusion element beats the filling cylinder to promote material discharge, the lower material control plate is acted on by the inclined rod to maintain a state of conduction with the upper material control plate to perform material discharge and filling. When the vibrating extrusion element is used to squeeze or resist the gums, the vibrating extrusion element will act on the lower material control plate synchronously through the inclined rod during the position change process, so that the lower material control plate and the upper material control plate form a staggered state, thereby achieving the blocking of bone powder, thereby facilitating the actual filling operation.

[0041] At the same time, when the vibrating extrusion element is beating to promote the discharge of bone powder, the angle of the transmission arm can be adjusted slightly, so that it can drive the staggered angle of the lower control plate and the upper control plate relative to the discharge chute through the action of the inclined rod, which is used to further control the amount of bone powder discharged, satisfying the practical adjustment in actual application conditions.

[0074] like Figures 1 to 13 As shown, an embodiment of the present invention provides a bone powder filler for oral implant surgery, including a filling tube 1 and a handle 2 connected to the end of the filling tube 1; a conical feeding portion 11 is extended outward from the bottom wall of the filling tube 1, and a vibrating extrusion element 3 is fixed between the conical feeding portion 11 and the filling tube 1, wherein a transmission element 4 connected to the vibrating extrusion element 3 is sleeved above the conical feeding portion 11, and a driving element 5 is also connected to the transmission element 4, and the driving element 5 can drive the vibrating extrusion element 3 to vibrate or extrude the transmission element 4 under the action of the driving element 5, and a feeding pipe 14 is also connected to the surface of the filling tube 1, and bone powder inside the filling tube 1 can be added through the feeding pipe 14.

[0075] It also includes an auxiliary expansion element 6 , which is arranged on the outside of the filling cylinder 1 and assembled through a connecting piece 61 .

[0076] The bottom wall of the filling cylinder 1 has a discharge port 12, and the discharge port 12 is connected to a storage chamber 13 in the filling cylinder 1, wherein a material control element 7 is installed at the position of the discharge port 12, and the vibration extrusion element 3 is connected to the material control element 7 for vibration discharge or extrusion sealing of bone powder.

[0077] The vibration extrusion element 3 includes a support ring 31 fixed on the filling tube 1 , an annular groove 38 opened on the outer side of the support ring 31 , a support seat 32 slidably arranged in the annular groove 38 , and a transmission arm 33 movably arranged on the inner side of the support seat 32 .

[0078] like Figure 6As shown, the two sides of the transmission arm 33 extend outward with a pivot 34 movably connected to the support seat 32, and a torsion spring 35 is sleeved on the pivot 34. The two ends of the torsion spring 35 are respectively connected to the corresponding support seat 32 and the transmission arm 33. In the natural state, the bottom of the transmission arm 33 is in a state of resistance toward the outer wall of the filling cylinder 1 due to the action of the torsion spring 35. A convex ball 330 is fixed to the bottom of the bottom of the transmission arm 33, and a transmission rope 36 is connected to the top.

[0079] The torsion spring 35 shown in this embodiment gives the transmission arm 33 a resistance state of Figure 1 , Figure 2 , Figure 3 In the state shown, one end of the transmission arm 33 having the convex ball 330 is in contact with the outer wall of the filling cylinder 1 , and the other end is away from the outer wall of the filling cylinder 1 .

[0080] A limiting bolt 37 is threadedly provided on the support ring 31 for limiting the support seat 32. The support seat 32 can slide inside the annular groove 38 to adjust the position of the transmission arm 33 and the corresponding convex ball 330 thereon. By rotating the limiting bolt 37, one end of the limiting bolt 37 can abut against the surface of the support seat 32 to limit the support seat 32. Fig.12 As shown, if the support seat 32 needs to be adjusted to different angles, a bolt hole for the limit bolt 37 to pass through can be formed above the support ring 31 accordingly. The more bolt holes are opened, the more adjustable angles of the support seat 32 can be (only some bolt holes are shown in this embodiment).

[0081] After the transmission rope 36 on the transmission arm 33 is pulled by the transmission element 4, the contracted transmission rope 36 will pull the top end of the transmission arm 33 toward the filling cylinder 1, while the other end and the convex ball 330 thereon will move away from the filling cylinder 1. When the transmission rope 36 is pulled, the transmission arm 33 is swung back to its original position due to the force of the torsion spring 35.

[0082] After the transmission arm 33 is swung back to its original position, the convex ball 330 at the bottom will hit the outer wall of the filling tube 1. By continuously repeating the above steps, the outer wall of the filling tube 1 can be hit back and forth. The filling tube 1 hit will promote the discharge of bone powder therein, so that it can be filled in the gap around the implant during oral implant surgery. The amount of bone powder discharged can be roughly controlled by controlling the frequency of the hitting. The handle 2 can be held in one hand for single-handed operation, which effectively facilitates actual use. At the same time, the filling tube 1 can protect unused bone powder and prevent it from being scattered.

[0083] The above-mentioned bone powder will be concentratedly stored inside the filling cylinder 1 before filling. Since the bone powders have corresponding adhesion (refer to flour), the bone powder inside the filling cylinder 1 will not be directly discharged continuously through the conical discharge part 11, but needs to be struck and vibrated to promote its orderly discharge for filling and use, so that the operator can better grasp the amount of bone powder filling during the planting process.

[0084] The transmission element 4 includes a shell 41 fixed to the top of the filling tube 1 , a sliding plate 42 slidably arranged on the inner wall of the shell 41 , and a supporting spring 43 arranged on the sliding plate 42 and connected to the top wall of the shell 41 .

[0085] Among them, the bottom wall of the sliding plate 42 is connected to a transmission rod 44, and one end of multiple transmission rods 44 extends to the outside of the shell 41 and is commonly connected to a rotating ring 45. Under the natural state, after being acted upon by the support spring 43, the sliding plate 42 will resist the bottom wall of the shell 41.

[0086] The bottom wall of the rotating ring 45 is movably connected with a transmission ring 46 for connecting the transmission rope 36. The rotating ring 45 is fixedly sleeved on the outer wall of the filling cylinder 1. The transmission ring 46 can rotate on the surface of the rotating ring 45 to adjust the angle of the transmission arm 33 connected thereto.

[0087] like Fig.10 As shown, after the initial filling of the gap around the implant in the oral implant surgery, it is necessary to promote further tightness of the bone powder after filling, so it is necessary to adjust the position of the vibrating extrusion element 3 to form an extrusion state, and the specific steps are as follows:

[0088] The limiting bolt 37 is taken out, and then the inclined rod 74 is rotated inside the annular groove 38. After the transmission arm 33 is rotated 180 degrees, the adjusted support seat 32 is limited and fixed by the limiting bolt 37. At this time, the handle 2 and the structure thereon can be tilted with the help of the supporting effect of the auxiliary support element 6. The tilted convex ball 330 is located above the implant. Then, after the transmission rope 36 is pulled by the transmission element 4, the transmission arm 33 will drive the convex ball 330 thereon to swing toward the implant. The convex ball 330 hits the implant and its surroundings, thereby generating vibration with the implant. The vibration promotes the compactness of the bone powder after filling. If the bone powder protrudes from the surface of the implant, it can also be directly accumulated on the surface of the bone powder through the convex ball 330. After the bone powder is squeezed, it can produce synchronous squeezing of the bone powder below it, thereby further promoting the compactness of the filled bone powder, which is conducive to the subsequent more stable use of the implant.

[0089] The driving element 5 includes a driving rope 51 arranged in the handle 2 .

[0090] One end of the driving rope 51 extends into the shell 41 and is fixed to the center of the sliding plate 42, and the other end is also connected to a toggle block 52, which is slidably assembled inside the handle 2. Toggling the toggle block 52 can make it slide along the length direction of the handle 2 to form a tensioning drive for the driving rope 51.

[0091] like Figure 1 and Figure 2 As shown, when the vibration extrusion element 3 vibrates and fills the bone powder, and as Fig.10 As shown, when the vibration extrusion element 3 is adjusted to perform extrusion to promote the densification of the bone powder, the specific steps of driving the transmission rope 36 through the transmission element 4 and the driving element 5 are as follows:

[0092] The fingers hold the handle 2, and the thumb pushes the toggle block 52 to slide along the end of the handle 2. When the toggle block 52 slides, it will drive the driving rope 51 on it to move synchronously. The driving rope 51 will overcome the force of the supporting spring 43 to make the sliding plate 42 slide upward. When the sliding plate 42 slides, the rotating ring 45 and the transmission ring 46 are pulled up through multiple transmission rods 44 to form a pulling effect on the driving rope 51. The driving rope 51 under the tension will drive the transmission arm 33 to deflect, so as to achieve the impact or collision of the convex ball 330.

[0093] The material control element 7 includes an upper material control plate 71 installed in the discharge port 12 and a lower material control plate 72 arranged close to the upper material control plate 71, wherein a guide funnel 73 is fixed to the outer side of the lower material control plate 72, an inclined rod 74 is fixed to one side of the top of the guide funnel 73, and a connecting slider 75 is fixed to one end of the inclined rod 74. The connecting slider 75 is slidably arranged in the annular groove 38 and fixed to the support seat 32.

[0094] The surfaces of the upper material control tray 71 and the lower material control tray 72 are both provided with corresponding material discharge grooves 76 , and the vibrating extrusion element 3 is rotated so that the inclined rod 74 drives the lower material control tray 72 to rotate relative to the upper material control tray 71 .

[0095] like Figure 1 and Figure 2 As shown, when the vibrating extrusion element 3 vibrates and fills the bone powder, the discharge grooves 76 on the upper control plate 71 and the lower control plate 72 are in a corresponding state. The bone powder inside the filling tube 1 can be discharged into the gap around the external implant through the upper and lower corresponding discharge grooves 76 for filling. If it is necessary to further adjust the amount of bone powder discharged each time after being hit, the limit bolt 37 is removed, and the position of the connecting slider 75 sliding inside the annular groove 38 is adjusted. When the connecting slider 75 slides, the inclined rod 74 thereon will drive the lower control plate 72 to rotate relative to the upper control plate 71. The lower control plate 72 in the rotating state and the discharge grooves 76 on the upper control plate 71 corresponding to the upper side are in a staggered state (such as Fig.13As shown in the figure), by adjusting the different staggered gaps, the amount of bone powder discharged after beating can be adjusted.

[0096] like Fig.10 As shown, when the vibration extrusion element 3 is adjusted to extrude and promote the densification of bone powder, at this time, since the connecting slider 75 is slid and adjusted one hundred and eighty degrees, the discharge groove 76 on the lower control plate 72 after sliding is not in a corresponding state with the discharge groove 76 on the upper control plate 71, thereby forming a blocking effect on the discharge groove 76, so that the bone powder inside the filling tube 1 cannot be discharged, so as to meet the extrusion and vibration of the vibration extrusion element 3 on the bone powder after filling in the gap around the implant in oral surgery.

[0097] The auxiliary expansion element 6 includes a support body 62 and tooth support areas 63 formed at two ends of the support body 62 .

[0098] The support body 62 is provided with a strip groove 64 and an adjustment groove 65 on one side opposite to the filling tube 1 .

[0099] There are a plurality of adjustment grooves 65 , which are distributed perpendicular to the strip grooves 64 . The plurality of adjustment grooves 65 are arranged on the support body 62 at equal intervals and communicate with the strip grooves 64 .

[0100] The connecting member 61 includes a connecting column 610, a universal ball 611 fixedly connected to the end of the connecting column 610, and a ball seat 612 movably wrapped around the surface of the universal ball 611, wherein the connecting column 610 is fixedly connected to the shell 41, and the ball seat 612 is slidably arranged in the adjustment groove 65.

[0101] An anti-skid protrusion 613 is fixed on the ball seat 612 , and a matching groove 614 matching with the anti-skid protrusion 613 is provided in the adjustment groove 65 .

[0102] like Fig. 9 As shown, before performing an oral implant surgery on a patient, the support body 62 can be placed in the patient's mouth first, and support for the upper and lower gums can be formed through the upper and lower tooth support areas 63. Then, its position is adjusted so that the conical discharge portion 11 on the filling tube 1 is located above the implant to be implanted. The support body 62 can be used to support the oral cavity, so that the patient's mouth can be in an open state, which is convenient for filling the bone powder in the space around the implant on the patient's lower gum.

[0103] Since the vibrating extrusion element 3 is movably connected to the support body 62 through the connecting piece 61, in the actual application process of discharging and filling the bone powder by beating and vibration, the operator can adjust the angle of the filling tube 1 during discharging within a certain range through the handle 2 to expand the range of operation without frequent position adjustment. At the same time, the connecting piece 61 can be used with the help of a certain supporting force to assist the operator's one-handed operation, making the movement more stable during the filling process.

[0104] While adjusting the vibration extrusion element 3 to form Fig.10 As shown in the figure, when the implant after filling is vibrated to promote the densification and extrusion of bone powder, the angle of the handle 2 can be adjusted in cooperation with the function of the universal ball 611, so that the handle 2, the filling cylinder 1 and the transmission arm 33 thereon can swing at a certain angle together, and then the convex ball 330 can be adjusted to the corresponding position on the implant with the support and connection function of the connecting column 610, for example, by sliding the toggle block 52 to make Fig.10 When the transmission arm 33 is opened, the convex ball 330 will hit the gums around the implant, causing vibration around the implant and promoting the compaction of the bone powder after filling inside. At the same time, the convex ball 330 can also be directly flipped to make it contact with the surface of the bone powder, thereby achieving resistance to the bone powder and squeezing the filled bone powder. The angle of the handle 2 in this state can be adjusted accordingly according to the actual application.

[0105] By using a plurality of adjustment grooves 65 in conjunction with a single strip groove 64, the ball seat 612 can slide on the strip groove 64 to a suitable height and then slide horizontally into the corresponding adjustment groove 65. By engaging the anti-slip protrusion 613 and the matching groove 614, the filling height of the filling tube 1 can be adjusted and the stability of the ball seat 612 and the adjustment groove 65 after adjustment can be ensured.

[0106] The workflow of the technical solution of the present invention is as follows:

[0107] The auxiliary expansion element 6 is placed between the patient's upper and lower gums for expansion. After the filling tube 1 is adjusted to a suitable position, the driving element 5 drives the transmission element 4 so that the vibration extrusion element 3 thereon strikes the filling tube 1 for intermittent material feeding and filling. The vibrating extrusion element 3 can also be rotated slightly to adjust the material feeding amount of the feeding trough 76. After the initial filling is completed, the vibrating extrusion element 3 can be adjusted to be in an extrusion state. Then, the driving element 5 controls the convex ball 330 to form a patting around the implant to promote the compaction of the bone powders. The convex ball 330 can also be controlled to cooperate with the action of the handle 2 to form a direct extrusion of the bone powder to further achieve the compaction of the bone powder after filling around the implant.
