Description

Technical Field

[0001] This utility model relates to the field of dental implant medical device technology, specifically to a dental implant device with a microfluidic channel. Background Technology

[0002] Dental implant technology, as the mainstream solution for repairing missing or damaged teeth, has been widely used in clinical practice. Its core principle is to implant a biocompatible implant into the alveolar bone, form a stable mechanical support through the osseointegration process, and then connect the prosthesis through the abutment to achieve the replacement of the function of natural teeth. However, during the postoperative healing phase, the nutritional supply of the tissues surrounding the implant depends on natural blood circulation. In patients with poor osseointegration, insufficient local blood supply will prolong the healing period, making it difficult to prevent and treat peri-implantitis. Postoperative bacteria can easily proliferate at the implant-gingival interface, causing inflammation. Existing treatment methods have problems such as low drug concentration, short duration of action, and significant systemic side effects. Utility Model Content

[0003] The purpose of this invention is to provide an oral implantation device with a microfluidic channel to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an oral implantation device with a microfluidic channel, comprising an implantation base and a fixing component, wherein a threaded groove is provided on the outer side of the implantation base and a placement cavity is provided on the inner side of the implantation base; A fixing component is fixedly provided at the upper end of the implant base. The fixing component includes a fixing thread opened on the inner side of the top end of the implant base. A retention screw is fixedly provided at the top end of the implant base, and the bottom end of the retention screw is engaged with the fixing thread. A main channel is opened on the inner side of the retention screw. An implantation component is fixedly disposed at the top of the retention screw, and a microfluidic component is fixedly disposed on the inner side of the placement cavity.

[0005] Preferably, the retaining screw is arranged in an inverted conical shape.

[0006] Preferably, the implant component includes an implant crown fixedly disposed at the top of the retention screw, and a sealing gasket is fixedly disposed at the bottom end of the retention screw.

The outer side of the connecting pipe is provided with an external thread, and the internal thread and the external thread are engaged.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This oral implant device with microfluidic channels features a sealing gasket at the bottom of the retention screw that fits tightly against the outer side of the implant's fixing threads during installation. This effectively prevents saliva, food debris, and bacteria from entering the implant's placement cavity or microfluidic channel. Furthermore, the branch tubes can be adjusted according to the bone morphology around the implant to ensure precise alignment of the sustained-release micropores with the gingival interface requiring medication. During injection, the micropump actively controls the flow rate and dosage, allowing for precise adjustment of the drug release rhythm based on clinical needs. The circumferential arrangement of multiple branch tubes allows medication to cover the entire sidewall area of ​​the implant via different pathways. Combined with the circumferential distribution of the sustained-release micropores, this achieves comprehensive, seamless drug delivery to the tissues surrounding the implant. The hydrophilic modification of the micropore's inner wall allows the drug solution to penetrate the tissue more smoothly, preventing drug residue from clinging to the channel walls. Simultaneously, the porous polylactic acid-glycolic acid copolymer film is a biodegradable biomaterial that avoids long-term retention in the body causing foreign body irritation and prevents bacteria and tissue cells from invading the channel, reducing the risk of infection and blockage.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-3 The present invention provides a technical solution: an oral implantation device with microfluidic channel, including an implantation base 1 and a fixing component 2, wherein a threaded groove 11 is provided on the outer side of the implantation base 1 and a placement cavity 12 is provided on the inner side of the implantation base 1. A fixing component 2 is fixedly installed at the upper end of the implant base 1. The fixing component 2 includes a fixing thread 21 opened on the inner side of the top of the implant base 1. A retaining screw 22 is fixedly installed at the top of the implant base 1, and the bottom end of the retaining screw 22 is threaded with the fixing thread 21. A main channel 23 is opened on the inner side of the retaining screw 22.

[0016] Specifically, the threaded groove 11, fixing thread 21, and retention screw 22 of the implant base 1 form a double threaded fixation, which has stronger anti-rotation and anti-loosening capabilities, can better withstand the complex load during chewing, and makes the assembly or disassembly of the implant base 1 and retention screw 22 more convenient. It can be quickly positioned and installed during surgery. If the microfluidic channel needs to be maintained after surgery, it is not necessary to disassemble the entire implant. It can be operated by simply turning the retention screw 22, reducing the risk of secondary trauma.

[0017] exist Figures 1-2 In the middle: The top end of the retention screw 22 is fixedly provided with an implant component 3, which includes an implant crown 31 fixedly provided at the top end of the retention screw 22, and a sealing gasket 32 ​​is fixedly provided at the bottom end of the retention screw 22.

[0018] Specifically, the sealing gasket 32 ​​at the bottom of the retaining screw 22 can fit tightly against the outer side of the fixing thread 21 of the implant base 1, effectively preventing saliva, food residue, and bacteria in the oral cavity from entering the placement cavity 12 or microfluidic channel of the implant base 1, and also preventing accidental leakage of drug growth factors in the channel, ensuring that the drug acts on the target area.

[0019] exist Figures 1-6 In the middle: a microfluidic component 4 is fixedly installed on the inner side of the placement cavity 12. The microfluidic component 4 includes a placement groove 41 opened on the inner side of the bottom end of the fixing screw 22. A micro pump 42 is fixedly installed on the inner side of the placement groove 41. The bottom end of the micro pump 42 is circumferentially connected to multiple sets of branch tubes 43. Multiple sets of slow-release micropores 44 are circumferentially opened on the side of the implantation base 1. The inner wall of the slow-release micropores 44 is hydrophilically modified and a porous polylactic acid-glycolic acid copolymer film is provided.

[0020] Specifically, the micropump 42 can actively control the flow rate and dosage, and can precisely adjust the drug release rhythm according to clinical needs, avoiding the problems of burst release waste or insufficient dosage. The multiple branch tubes 43 are arranged in a circumferential pattern, which allows the drug to cover the entire side wall area of ​​the implant root 1 through different paths. Combined with the circumferential distribution of the sustained-release micropores 44, the drug can be delivered to the tissue around the implant in an all-round and dead-angle manner. Moreover, the hydrophilic modification of the inner wall of the sustained-release micropores 44 allows the drug solution to penetrate into the tissue more smoothly, avoiding drug residues on the channel wall. At the same time, the porous polylactic acid-glycolic acid copolymer film is a biodegradable biomaterial, which will not remain in the body for a long time and cause foreign body irritation, and can also block bacteria and tissue cells from invading the channel in reverse, reducing the risk of infection and blockage.

[0021] exist Figures 5-6 In the middle: An adjusting component 5 is fixedly installed on the inner side of the branch pipe 43. The adjusting component 5 includes a connecting pipe 51 fixedly installed at the top of the branch pipe 43. The inner side of the connecting pipe 51 is provided with an internal thread 52. The bottom end of the branch pipe 43 is fixedly installed with a connecting pipe 53. The outer side of the connecting pipe 53 is provided with an external thread 54, and the internal thread 52 and the external thread 54 are threadedly engaged.

[0022] Specifically, the meshing design of the internal thread 52 and the external thread 54 allows the connecting tube 53 to rotate and extend relative to the opposing tube 51. It can adjust the end direction of the branch tube 43 according to the bone tissue morphology around the implanted root base 1, ensuring that the sustained-release micropore 44 is precisely aligned with the gingival interface where the medication is needed. Patients can periodically inject saline through the main channel 23 to flush the branch tube 43 with fluid pressure, preventing impurities from clogging it. If a branch tube 43 becomes blocked, the damaged section can be quickly disassembled by rotating the connecting tube 53 and replaced with a new branch tube 43 without disassembling the entire microfluidic component 4 or the implanted root base 1, significantly reducing maintenance trauma and costs. Furthermore, the tight meshing of the internal thread 52 and the external thread 54 ensures the sealing of the branch tube 43 connection, preventing medication leakage or the intrusion of oral contaminants. At the same time, the threaded connection has strong mechanical stability, can withstand slight vibrations during chewing, and is not easily loosened.

[0023] When performing the installation, medical staff can first install the implant base 1 in the patient's oral cavity. The retention screw 22 is inverted conical with a larger diameter at the top and a smaller diameter at the bottom, forming a wedge-shaped fit with the connection interface of the implant base 1. Then, the implant crown 31 can be installed on the upper end of the retention screw 22 by thread engagement. The sealing gasket 32 ​​and the conical surface can form a double seal. Medical staff can adjust the end of the branch tube 43 according to the bone tissue morphology around the implant base 1 to ensure that the slow-release micropore 44 is accurately aligned with the gingival interface that requires medication. When medical staff need to inject medication into the patient's gingival interface, the implanted crown 31 can be removed by means of threaded connection. At the same time, the external medication device can be connected to the micro pump 42 inside the retention screw 22 through the main channel 23. The micro pump 42 can actively control the flow rate and dosage. Through the circumferential layout of multiple branch tubes 43, the medication can cover the entire side wall area of ​​the implanted root 1 through different paths.

[0024] Electrical equipment (including but not limited to micro pumps) is safely powered by an external power source and controlled by a control box. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
