[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1 and Figure 2 As shown, the present invention provides an implant detector. The implant detector of this embodiment includes a sensor module 10, a connecting tube 20 and a handle 30. The sensor module 10 includes a probe 11 for detecting the location of the implant, and the probe 11 is provided with a through hole 111 for placing a periodontal probe. One end of the connecting tube 20 is detachably connected to the probe 11, and the other end of the connecting tube 20 is detachably connected to the handle 30. At least a portion of the connecting tube 20 can be bent to drive the probe 11 to change its angle.

[0030] In the above technical solution, a bendable connecting tube 20 is provided, and the sensor module 10 and the handle 30 are connected through the connecting tube 20, so that the angle of the probe 11 can be changed. In this way, the implant position can be detected between the maxillary and mandibular parts according to actual conditions, thereby simplifying the doctor's clinical operation.

[0031] Specifically, the implant can be contacted by a periodontal probe disposed in the through hole 111 to accurately detect the implant position under the gingival tissue.

[0032] In addition, since both ends of the connecting tube 20 are detachably connected to the probe 11 and the handle 30 respectively, subsequent maintenance and cleaning and sterilization are convenient.

[0033] In the embodiment of the present invention, the connecting pipe 20 is rotatably disposed relative to the handle 30 along a predetermined axis.

[0034] In the above technical solution, the connecting tube 20 is rotatably arranged relative to the handle 30 along a predetermined axis, thereby driving the probe 11 to rotate, thereby changing the direction of the probe 11, making it easier to find the position of the implant in the alveolar bone, and greatly simplifying the doctor's clinical operation.

[0035] like Figure 4 As shown, in an embodiment of the present invention, the probe 11 includes a coil 115, and the sensor module 10 also includes an oscillation circuit connected to the coil 115. The oscillation circuit generates a current of a constant frequency and transmits the generated alternating current to the coil 115. When a current of a certain frequency is transmitted to the coil 115, a magnetic field is generated around the coil 115. When the coil 115 that generates the magnetic field approaches the object to be detected, the current flows in the object to be detected and forms a reverse magnetic field that interferes with the magnetic field of the coil 115, which causes the magnetic field of the coil 115 to weaken, thereby causing the voltage to change. In this way, the position of the implant can be accurately determined by the induced electromotive force generated at both ends of the coil 115. The above-mentioned technology for detecting the position of the implant using the metal detection principle is a prior art and will not be repeated here.

[0036] like Figure 2 , Figure 5 and Figure 7 As shown, in an embodiment of the present invention, a mounting pipe section 40 is provided at one end of the handle 30, and the mounting pipe section 40 has a mounting hole 41. A boss 21 is provided at the end of the connecting tube 20 away from the probe 11, and a mounting groove 22 is provided on the outer wall surface of the boss 21. The implant detector also includes a first elastic member 221 located in the mounting groove 22, and the boss 21 is interference fit with the handle 30 through the first elastic member 221. The first elastic member 221 has a telescopic property so that the connecting tube 20 can rotate.

[0037] In the above technical solution, since the first elastic member 221 has telescopic properties, under the action of external force, the first elastic member 221 can drive the connecting tube 20 to rotate around the axis, thereby driving the probe 11 to change direction, facilitating the subsequent accurate detection of the specific position of the implant; further, since the first elastic member 221 and the mounting hole 41 are interference fit, by controlling the interference amount, a sealed connection between the mounting tube section 40 and the connecting tube 20 can be achieved, thereby preventing blood and water from entering the inside of the connecting tube 20 during surgery.

[0038] like Figure 5 As shown, in the embodiment of the present invention, the boss 21 has a first through hole connected to the interior of the connecting tube 20. The boss 21 includes a first shaft segment, a second shaft segment and a third shaft segment connected in sequence, the first shaft segment is connected to the connecting tube 20, and the mounting groove 22 is opened on the outer periphery of the third shaft segment.

[0039] In the above technical solution, a mounting groove 22 is provided on the outer periphery of the third axis segment of the boss 21, and the boss 21 cooperates with the handle 30 through a first elastic member 221 arranged on the mounting groove 22, and the third axis segment plays a limiting role; the second axis segment has a larger diameter and a larger space inside for convenient wire installation; the first axis segment is set to a smaller diameter, so that the overall weight of the implant detector is lighter and easier to operate.

[0040] Preferably, the mounting groove 22 is an annular groove. Preferably, the first elastic member 221 is an O-ring. In this way, an interference fit between the boss 21 and the handle 30 can be achieved in the entire circumference; further, sealing can also be achieved.

[0041] In the embodiment of the present invention, the probe 11 is rotatably arranged relative to the connecting tube 20. In this way, the direction of the probe 11 can be further changed, and various complex situations such as detecting the loss of upper and lower jaws, single teeth, multiple teeth, anterior teeth, and posterior teeth can be handled, so as to facilitate and accurately detect the position of the implant in the oral cavity.

[0042] like Figure 2 and Figure 3 As shown, in an embodiment of the present invention, a slot 112 is provided at one end of the probe 11, and the implant detector also includes a second elastic member 113, which is located in the slot 112. The second elastic member 113 is interference fit with the tube mouth at one end of the connecting tube 20, thereby sealing and connecting the probe 11 and the connecting tube 20, and the second elastic member 113 has a telescopic property, and under the action of external force, the probe 11 can rotate relative to the connecting tube 20.

[0043] In the above technical solution, a sealed connection is achieved through the interference fit between the probe 11 and the connecting tube 20, thereby preventing blood or other dirt generated during the detection process from entering the interior of the connecting tube 20 through the probe 11, which is convenient for subsequent maintenance and cleaning and sterilization; in addition, since the second elastic member 113 has telescopic properties, under the action of external force, the second elastic member 113 can drive the probe 11 to rotate around the axis, thereby realizing the free rotation of the probe 11 in any direction and at any angle to cope with the detection of various complex situations.

[0044] Preferably, the second elastic member 113 is an O-ring.

[0045] In the embodiments not replaced in the drawings, it can also be arranged according to actual conditions that only the connecting tube 20 is rotatable relative to the handle 30 , or only the probe 11 is rotatable relative to the connecting tube 20 .

[0046] like Figure 3 and Figure 5 As shown, in an embodiment of the present invention, the implant detector also includes a shoulder 114 located on the outer periphery of the probe 11, a connecting head 23 is provided at one end of the connecting tube 20, the outer diameter of the shoulder 114 is larger than the outer diameter of the connecting head 23, and the end face of the shoulder 114 matches the end face of the connecting head 23.

[0047] Through the above-mentioned arrangement, the connecting tube 20 and the probe 11 can achieve axial positioning to avoid relative displacement during operation; since the outer diameter of the shoulder 114 is larger than the outer diameter of the connector 23, the blood generated during the detection process flows out along the outer edge of the shoulder 114, effectively preventing the blood from entering the connecting tube 20 along the probe 11.

[0048] In the embodiment of the present invention, the connecting tube 20 is made of a metal hose, such as medical grade materials such as 304 and 316 stainless steel, which has good flexibility, tensile strength, corrosion resistance, and wear resistance, so that the probe can be bent in any direction and at any angle, and can cope with various complex situations such as detecting the loss of upper and lower teeth, single teeth, multiple teeth, anterior teeth, and posterior teeth.

[0049] like Figure 1 and Figure 6 As shown, in an embodiment of the present invention, the implant detector also includes a connecting sleeve 50 for connecting the handle 30 and the connecting tube 20. The connecting sleeve 50 is arranged on the outer periphery of the mounting pipe section 40. The inner wall surface of the connecting sleeve 50 is provided with an internal thread, and the outer wall surface of the mounting pipe section 40 is provided with an external thread matching the internal thread to connect the mounting pipe section 40 and the connecting sleeve 50.

[0050] In the above technical solution, the way in which the external threads on the outer wall surface of the installation pipe section 40 cooperate with the internal threads on the inner wall surface of the connecting sleeve 50 is simple and easy to operate.

[0051] like Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a step hole 51 is provided on the inner wall surface of the connecting sleeve 50, and the step hole 51 includes a first hole section 511 and a second hole section 512 connected to each other, and a second step surface 52 is formed between the first hole section 511 and the second hole section 512, and a first step surface 211 is provided on the boss 21, and the first step surface 211 abuts against the second step surface 52.

[0052] Through the above arrangement, the second step surface 52 abuts against the first step surface 211 , which can limit the axial displacement of the boss 21 , thereby limiting the axial displacement of the connecting pipe 20 and axially positioning the connecting pipe 20 .

[0053] like Figure 4 and Figure 7 As shown, in the embodiment of the present invention, the probe 11 includes a coil 115, and the implant detector further includes a control unit 31, a power supply 32, and a prompt device 33. The control unit 31 is located in the handle 30; the power supply 32 is located in the handle 30; the prompt device 33 is arranged on the handle 30, the prompt device 33 is connected to the control unit 31, the power supply 32 is electrically connected to the coil 115, and the control unit 31 controls the prompt device 33 to feedback the detection result according to the signal transmitted by the coil 115.

[0054] Through the above arrangement, the power supply 32 generates current and transmits it to the coil 115. Induced electromotive force is generated at both ends of the coil 115. The voltage signal is amplified and processed and transmitted to the control unit 31 located in the handle 30. The control unit 31 converts the transmission signal into different output signals and outputs prompts through the prompt device 33 to prompt the doctor of the position of the implant under the gums.

[0055] It should be noted that when the detector is working, when the probe 11 contacts the implant, the voltage in the coil 115 will change and be transmitted to the control unit 31. The control unit 31 outputs a corresponding signal to the prompt device 33 based on the received voltage signal, and the prompt device 33 sends a corresponding prompt information (for example, sound information or light information) based on the signal.

[0056] In an embodiment of the present invention, the prompt device 33 includes a light emitting member or a sound generator. In the above configuration, when the prompt device emits a sound or the display light turns on, it prompts the doctor that the position of the implant has been detected.

[0057] Of course, in other embodiments, the prompting device 33 also emits light information of different frequencies or colors, or emits sound information of different frequencies according to the input position information, so as to prompt the doctor of the position of the implant under the gums.

[0058] like Figure 7As shown, in an embodiment of the present invention, the implant detector further includes a wire 60 , a wire hole 34 for the wire 60 to pass through is provided on the handle 30 , and the power source 32 is connected to the control unit 31 via the wire 60 .

[0059] Through the above arrangement, the power supply 32 is connected to the control unit 31 via the wire 60, and the control unit 31 can realize the conversion and processing of the sensor signal.

[0060] Specifically, when the prompt device 33 is a light-emitting element, at least a portion of the prompt device 33 is located on the outer wall surface of the handle 30, so that the operator can check the detection result conveniently (for example, the light-emitting element lights up to indicate that the implant is detected).

[0061] In an alternative embodiment not shown in the drawings, when the prompt device 33 is a sound generator, the prompt device 33 can be located inside the handle 30 or outside the handle 30 .

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
