Description

Technical Field

[0001] The present invention relates to the technical field of oral implantology, and more specifically, it relates to a positioning device for edentulous oral implantology. Background Art

[0002] Dental implantation refers to a tooth defect repair method that uses the lower structure implanted in bone tissue to support and retain the upper dental prosthesis, including two parts: the lower supporting implant and the upper dental prosthesis, mainly for the treatment of tooth defects and losses.

[0003] A Chinese invention patent with publication number CN115153926A discloses a positioning device for edentulous oral implantology. This positioning device for edentulous oral implantology includes a support and limit structure. One side of the support and limit structure is equipped with a position adjustment structure, and a positioning plate for implant positioning is fixedly installed on one side inside the position adjustment structure. An angle adjustment structure for adjusting the angle between the position adjustment structure and the positioning plate is installed on one side of the position adjustment structure, and a moving structure for adjusting the position of the positioning structure is provided on one side of the angle adjustment structure.

[0004] Although this positioning device for edentulous oral implantology is provided with a support and limit structure, it is convenient to support and open the patient's oral cavity, thereby facilitating the relative fixation of the patient's dental bed, avoiding the deviation of the positioning structure caused by the movement of the dental bed. At the same time, in combination with the use of structures such as the position adjustment structure and the positioning plate, it is convenient to perform all-round movement adjustment according to the implant position, thereby meeting the needs of edentulous oral implantology and improving the use value of the positioning device.

[0005] However, the support and limit structure in this type includes a fixed cylinder, and a piston is movably arranged inside the fixed cylinder. A moving rod is fixedly connected to the top of the piston, and a protective sleeve head is sleeved on the top end of the moving rod. An extrusion plate is fixedly connected to the outer wall of the fixed cylinder, and a clamping strip is fixedly connected to one side of the extrusion plate. A limiting strip is arranged outside the clamping strip, and a connecting pipe is fixedly connected to one side inner wall of the fixed cylinder. An extrusion airbag is fixedly installed at one end of the connecting pipe. When supporting the patient's oral cavity, the patient's oral cavity is supported by moving the moving rod upward. Therefore, the support and limit structure is located between the maxilla and mandible of the patient's oral cavity. And because the area of the patient's open oral cavity is limited, it causes medical staff to avoid the support and limit structure when performing oral implantation on the patient, thus affecting the surgical operation of medical staff. At the same time, when flushing the implantation site of the patient, medical staff need to hold the flushing pipe to flush the implantation site of the patient's oral cavity. And during the flushing process, if the flushing fluid in the patient's oral cavity is not pumped out in time, it will cause the flushing fluid to flow from the patient's oral cavity to the pharyngeal part, thus stimulating the patient's swallowing function and causing the patient to swallow part of the flushing fluid into the abdomen, which not only affects the patient's physical health but also brings inconvenience to medical staff.

[0039] Refer to Figures 1 to 8 .

[0040] This embodiment further illustrates a positioning device for edentulous oral implant proposed by the present invention.

[0041] A positioning device for edentulous oral implant includes a support frame 1, a support rod 2 is slidably connected to the upper surface of the support frame 1, and also includes an upper positioning plate 3 and a lower positioning plate 4.

[0042] Both the upper positioning plate 3 and the lower positioning plate 4 are arc-shaped, and the ends of the upper positioning plate 3 and the lower positioning plate 4 are rotatably connected. Operation holes 5 are provided on both the upper positioning plate 3 and the lower positioning plate 4. Medical staff can implant the implant into the patient's oral cavity through the operation holes 5, so as to facilitate determining the implant position in the patient's oral cavity.

[0043] A control rope 6 is rotatably connected to the side wall of the upper positioning plate 3. One end of the control rope 6 is fixedly connected to the upper end of the support rod 2. The upper positioning plate 3 is installed on the upper gum of the patient, and the lower positioning plate 4 is installed on the lower gum of the patient. When the support rod 2 moves, the upper positioning plate 3 is pulled upward, so as to facilitate opening the patient's oral cavity, and thus facilitate the medical staff to implant the implant into the patient's oral cavity.

[0044] A pull rope 7 is fixedly connected to the side wall of the lower positioning plate 4. One end of the pull rope 7 is arranged at the end of the support frame 1.

[0045] A water blocking sheet 8 is fixedly connected between the upper positioning plate 3 and the lower positioning plate 4. The upper end and the lower end of the water blocking sheet 8 are respectively fixedly connected to the inner arc walls of the upper positioning plate 3 and the lower positioning plate 4. The water blocking sheet 8 is made of medical rubber material, which is convenient for the stretching and contraction of the water blocking sheet 8. When the medical staff flushes the part of the patient where the implant is planted, the water blocking sheet 8 can prevent the flushing liquid from entering the patient's oral cavity, so as to prevent the patient from having a swallowing reaction due to too much flushing liquid in the oral cavity.

[0046] At least two recovery holes 9 are formed in the circumferential wall of the operation hole 5 on the lower positioning plate 4, and an arc-shaped recovery cavity 10 is formed in the lower positioning plate 4. The recovery holes 9 are communicated with the arc-shaped recovery cavity 10. The recovery holes 9 can facilitate the flushing liquid to flow into the arc-shaped recovery cavity 10, so as to facilitate the collection and discharge of the flushing liquid.

[0047] A collection box 11 is fixedly connected to the side wall of the support frame 1. A suction pump 12 is fixedly connected to the bottom of the collection box 11. The inlet end of the suction pump 12 is fixedly connected to a connecting pipe 13. A liquid suction pipe 14 is fixedly connected to the side wall of the connecting pipe 13. The end of the liquid suction pipe 14 is communicated with the arc-shaped recovery cavity 10. The suction pump 12 is convenient for pumping out the liquid collected in the arc-shaped recovery cavity 10, so as to facilitate the discharge of the liquid collected in the arc-shaped recovery cavity 10. The upper end of the liquid suction pipe 14 is fixedly connected to a liquid extraction pipe 28. The lower end of the liquid extraction pipe 28 is close to the bottom of the arc-shaped recovery cavity 10, which is convenient for pumping out the liquid in the arc-shaped recovery cavity 10 through the liquid extraction pipe 28, so as to facilitate the discharge of the waste liquid in the arc-shaped recovery cavity 10.

[0048] The upper surface of the support frame 1 is provided with a strip-shaped groove 15. A fixing block 16 is fixedly connected to the side wall of the strip-shaped groove 15. A lead screw 17 is rotatably connected to the side wall of the fixing block 16. One end of the lead screw 17 is rotatably connected to the side wall of the strip-shaped groove 15. The lower end of the support rod 2 is threadedly connected to the lead screw 17, and the lower end of the support rod 2 is slidably connected in the strip-shaped groove 15. A sliding block is fixedly connected to the lower end of the support rod 2. A nut is fixedly connected to the sliding block. The nut is threadedly connected to the lead screw 17, and the sliding block is slidably connected in the strip-shaped groove 15, which is convenient for driving the support rod 2 to move horizontally through the thread on the lead screw 17. The cooperation between the strip-shaped groove 15 and the sliding block can effectively prevent the support rod 2 from rotating along with the rotation of the lead screw 17.

[0049] The end of the support frame 1 is fixedly connected with a servo motor 18. The output shaft of the servo motor 18 penetrates through the side wall of the support frame 1 and is fixedly connected to the end of the lead screw 17. The servo motor 18 can drive the lead screw 17 to rotate forward and backward, so as to facilitate the lead screw 17 to drive the support rod 2 to move back and forth.

[0050] A winding wheel 19 is rotatably connected to the side wall of the fixing block 16 far away from the lead screw 17. The rotating shaft on the winding wheel 19 passes through the fixing block 16 and is fixedly connected to the end of the lead screw 17. The lower end of the pull rope 7 is fixedly connected to the winding wheel 19. When the lead screw 17 drives the support rod 2 to move away from the fixing block 16, at this time, the winding wheel 19 winds the pull rope 7, so that the bending parts of the upper positioning plate 3 and the lower positioning plate 4 move in the opposite direction, so as to open the patient's oral cavity through the upper positioning plate 3 and the lower positioning plate 4.

[0051] Both the top of the collection box 11 and the upper end of the support rod 2 are fixedly connected with a flushing liquid loading box 20. A delivery pump 21 is fixedly connected to the bottom of the flushing liquid loading box 20. The output end of the delivery pump 21 is fixedly connected with a delivery pipeline 22. The end of the delivery pipeline 22 is matched with the operation hole 5.

[0052] Flushing liquid containing chambers 23 are respectively arranged in the upper positioning plate 3 and the lower positioning plate 4. The delivery pipeline 22 is communicated with the flushing liquid containing chamber 23. Both the delivery pipeline 22 and the liquid suction pipeline 14 are telescopic hoses, which is convenient for the delivery pipeline 22 and the liquid suction pipeline 14 to stretch or contract as the position of the support rod 2 moves.

[0053] At least two flushing holes 24 are arranged on the side wall of the operation hole 5. The flushing holes 24 are communicated with the flushing liquid containing chamber 23. The flushing holes 24 on the lower positioning plate 4 are located above the recovery hole 9, and the flushing liquid containing chamber 23 on the lower positioning plate 4 is located above the arc-shaped recovery cavity 10. The aperture value of the flushing holes 24 is smaller than the aperture value of the recovery hole 9, which is convenient for recycling the liquid accumulated in the patient's oral cavity.

[0054] A tongue pressing plate 25 is fixedly connected to the side wall of the water baffle 8. The tongue pressing plate 25 is close to the lower positioning plate 4. One end of the tongue pressing plate 25 away from the water baffle 8 is provided with a saliva absorption cotton 26. The saliva absorption cotton 26 absorbs the saliva in the patient's oral cavity, avoiding excessive saliva secreted in the patient's oral cavity and stimulating the patient to have a swallowing phenomenon, so as to reduce the number of times the patient swallows.

[0055] The tongue pressing plate 25 includes a connecting plate 27 and a mounting plate 29. The connecting plate 27 is fixedly connected to the lower end of the water baffle 8, and the mounting plate 29 is fixedly connected to the end of the connecting plate 27.

[0056] An installation groove 30 is formed in the side wall of the mounting plate 29. One end of the saliva absorption cotton 26 is located in the installation groove 30, and the other end of the saliva absorption cotton 26 is located outside the installation groove 30. A notch is formed at the top of the installation groove 30, and a fixing plate 31 is fixedly connected to the side wall of the notch by screws.

[0057] Saliva collection chambers 32 are formed in both the connecting plate 27 and the mounting plate 29. The two saliva collection chambers 32 are communicated with each other. A circular through hole 33 is formed at the bottom of the installation groove 30. A protruding portion 34 is arranged on the lower surface of the saliva absorption cotton 26. The protruding portion 34 is located in the circular through hole 33. When the saliva absorbed on the saliva absorption cotton 26 reaches the saturation state, the saliva on the saliva absorption cotton 26 drips downward through the protruding portion 34 into the saliva collection chamber 32, thus realizing the collection and discharge of saliva.

[0058] A discharge pipe 35 is fixedly connected to the connecting plate 27. The lower end of the discharge pipe 35 penetrates through the water baffle 8 and is communicated with the arc-shaped recovery cavity 10.

[0059] Arc-shaped clamping grooves 36 are formed on the upper surface of the upper positioning plate 3 and the lower surface of the lower positioning plate 4.

[0060] Working principle: When a patient undergoes edentulous oral implantation, the support frame 1 is placed on the patient's head, such that the support rods 2 are located on both sides of the patient's head, and the position of the winding wheel 19 is close to the patient's shoulders. The support frame 1 can be fixed to the operating bed on which the patient lies by means of existing technical means such as screws, thereby fixing the support frame 1 and preventing the position of the support frame 1 from shifting during use. Then, the upper positioning plate 3 and the lower positioning plate 4 are clamped on the upper and lower gums of the patient through the arc-shaped card slots 36. At the same time, the tongue depressor 25 is located above the patient's tongue, such that the lower surface of the tongue depressor 25 contacts the patient's tongue surface. Then, the servo motor 18 is started, and the output shaft of the servo motor 18 drives the lead screw 17 to rotate. During the rotation of the lead screw 17, the support rods 2 are driven to move away from the winding wheel 19. During the process of the support rods 2 moving away from the winding wheel 19, the upper positioning plate 3 is pulled away from the lower positioning plate 4 through the control rope 6. At the same time, during the rotation of the lead screw 17, the winding wheel 19 is driven to rotate, and during the rotation of the winding wheel 19, the pulling rope 7 is wound up, thereby pulling the lower positioning plate 4 downward through the pulling rope 7, so that the bent portion of the lower positioning plate 4 moves away from the upper positioning plate 3, thus realizing the opening of the patient's oral cavity, facilitating the medical staff to implant the implant into the patient's oral cavity.

[0061] When the medical staff implants the implant into the oral cavity, the medical staff can implant the implant at the patient's jawbone through the operation hole 5. During the process of implanting the implant, when bleeding occurs at the patient's wound site, the blood flows into the arc-shaped recovery cavity 10 through the recovery hole 9. At this time, the suction pump 12 is started, and the suction pump 12 pumps out the blood through the connecting pipe 13. When it is necessary to flush the patient's wound site, the delivery pump 21 is opened at this time. The delivery pump 21 delivers the flushing liquid loaded in the flushing liquid loading box 20 to the flushing liquid accommodation chamber 23 and sprays it out through the flushing holes 24, such that the flushing liquid is sprayed on the patient's wound, thereby realizing the flushing of the patient's wound site. The flushing liquid after flushing flows into the arc-shaped recovery cavity 10 through the recovery hole 9, thus facilitating the pumping out of the flushing liquid after flushing through the suction pump 12, avoiding the medical staff from holding the suction pipe to pump out the cleaning liquid in the patient's oral cavity. At the same time, through the blocking of the water blocking piece 8, it can effectively prevent the flushing liquid from flowing into the patient's oral cavity and flowing into the esophagus or trachea through the patient's pharynx, and at the same time avoid the patient swallowing the flushing liquid into the abdomen, ensuring the health of the patient, and also bringing convenience to the medical staff and the patient.

[0062] During the oral process, the patient's mouth is open. In the case of the patient's long-term opening, saliva will be secreted in the oral cavity. When there is saliva secreted in the patient's oral cavity, the saliva absorption cotton 26 absorbs the saliva secreted in the patient's mouth. When the saliva absorbed by the saliva absorption cotton 26 reaches the saturation state, the saliva on the saliva absorption cotton 26 drips downward through the protruding part 34 into the saliva collection chamber 32, so as to collect the excessive saliva in the patient's oral cavity. The collected saliva flows into the arc-shaped recovery cavity 10 through the discharge pipe 35, so as to facilitate pumping out the excessive saliva in the patient's oral cavity through the suction pump 12, thus avoiding frequent swallowing reactions due to excessive saliva secretion in the patient's oral cavity, and reducing the number of swallows of the patient during oral implantation. A discharge pipe is connected to the side wall of the collection box 11, and the end of the discharge pipe passes through the side wall of the collection box 11 and extends to the outside of the collection box 11, which is convenient for discharging the excessive waste liquid in the collection box 11.

[0063] Since the implantation positions of the implants are different for different patients, the operation hole 5 can be designed as an arc-shaped through hole, which is convenient for medical staff to implant the implant in different parts of the patient's oral cavity according to needs. Moreover, the materials of the upper positioning plate 3, the lower positioning plate 4, the tongue depressor 25 and the water baffle 8 are all medical high-temperature resistant materials, which is convenient for high-temperature sterilization treatment of the upper positioning plate 3, the lower positioning plate 4, the tongue depressor 25 and the water baffle 8, ensuring the cleanliness and hygiene of the upper positioning plate 3, the lower positioning plate 4 and the tongue depressor 25.

[0064] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
