Detailed Description
The invention will be further described with reference to the drawings and examples.
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
Embodiments of the invention and features of the embodiments may be combined with each other without conflict.
Example 1:
The OCT technology adopted by the invention particularly refers to an optical coherence tomography technology, is a newly developed non-invasive high-resolution optical imaging technology, has been widely applied in the field of medical imaging, can acquire tomographic images of tissue structures in real time, has the advantages of high resolution, high contrast and the like, and can be used for observing microstructure and lesion change of biological tissues.
As shown in fig. 1, the laboratory has verified that OCT has the ability to differentiate bone tissue, ligaments, muscle tissue, and that its clinical application in dentistry is also rapidly developing, especially in caries and restorative dentistry, the main goal of oral care is to preserve as much healthy tooth structure as possible, and therefore early non-invasive or minimally invasive treatment protocols are becoming more and more important, which place higher demands on diagnostic tools.
Taking bone grinding and drilling as an example in the implementation manner, some challenges still face applying OCT technology to bone grinding and drilling operations: the traditional OCT system has large volume and is difficult to integrate into a surgical tool, and the OCT system and the surgical tool are designed to realize effective coupling and integration; the abrasive drilling power system in the operation has a great deal of vibration and interference, which can influence the stability and accuracy of OCT imaging; most of grinding bits are disposable operation tools, so that the manufacturing cost is too high and the popularization is difficult.
In order to solve the problem of insufficient visualization of the traditional surgical bone grinding tool in the surgical operation and overcome the technical problem of applying the OCT technology to the surgical operation, the invention provides a grinding device which can realize real-time high-resolution imaging navigation, provide more accurate, safe and efficient orthopedic surgical operation for a surgeon, and can more accurately position the grinding depth of the surgical grinding tool in the surgical operation process by guiding the optical imaging technology, thereby improving the surgical success rate and the rehabilitation effect of patients.
As shown in fig. 2, the grinding device includes: the rotary part 1 and the handheld part 2, the tip of rotary part 1 is for grinding the ball head that bores, it has the cavity to open in the rotary part 1, grind and bore the ball head go up open with the light through-hole 8 of cavity intercommunication, can form focus facula 9 on external tissue through light through-hole 8, be equipped with adjusting screw 10 in the cavity for the angle of adjustment plane mirror.
The handheld component 2 is connected with a driving mechanism for driving the rotating component 1 to rotate, the handheld component 2 is connected with a capillary tube extending into the cavity, an optical fiber is arranged in the capillary tube and connected with the ball lens 6, and a plane reflecting mirror 7 matched with the optical through hole 8 and the ball lens 6 is arranged in the cavity.
Conventional optical fiber-based OCT is used in the field of endoscopes, and the scanning power sources are divided into two types: the miniature motor is arranged in the tail end of the endoscopic needle, and the optical fiber slip ring at the near end rotates to drive the torque spring so that the endoscope at the far end is enabled. The invention has no built-in micro motor at the tail end, because the built-in micro motor also solves the problem of independent power supply, the power supply wire can cause larger shielding to imaging, and the micro motor has high price, so the design cost of the invention is greatly reduced.
In the implementation mode, the optical fiber comprises a single-mode optical fiber 4 and a coreless optical fiber 5, the single-mode optical fiber 4 is arranged in a capillary, the single-mode optical fiber 4 is connected with the coreless optical fiber 5, and the coreless optical fiber 5 is connected with a ball lens 6; the invention is based on the method of the optic fibre, but can realize the rotary scanning without using the optic fibre slip ring, the price of a optic fibre slip ring is more than about two ten thousand yuan, the price of a direct-current motor 11 and driver 26 which drive the optic fibre slip ring to rotate is more than about 1 ten thousand yuan, therefore, the invention can save the cost of this part compared with existing scheme; the light transmission efficiency of the optical fiber slip ring is about 50% -70%, so that the optical power of the sample arm is improved, and the higher signal-to-noise ratio of the system is ensured.
In this implementation manner, optionally, the driving mechanism includes a dc motor 11, a synchronizing wheel 13 and a speed reducer 12, where the dc motor 11 is fixed in the handheld component 2, an output end of the dc motor 11 is connected with the synchronizing wheel 13, and the synchronizing wheel 13 is connected with the rotating component 1 through the speed reducer 12.

It will be appreciated that in other implementations, other rotary drive mechanisms may be employed for the drive mechanism; for example, a brushless motor fixed in the hand-held member 2 may be employed, the output end of which is connected to the rotary member 1; or a stepping motor with a hollow shaft can be adopted, and the output end of the stepping motor with the hollow shaft is directly connected with the rotating component 1; or the driving mechanism can adopt a gear transmission mechanism or a chain transmission mechanism for driving the rotating component 1 to rotate; those skilled in the art may choose according to specific working conditions, and will not be described here again.
In this implementation, the light through hole 8 is formed at the side of the grinding ball head, and optionally, the direction of the light through hole 8 is perpendicular to the light emitting direction of the ball lens 6, that is, plane reflection will reflect light perpendicularly.
It will be appreciated that, in other implementations, the direction of the light through hole 8 may not be perpendicular to the light emitting direction of the ball lens 6, as shown in fig. 3, so long as the light path between the light through hole 8 and the ball lens 6 can be constructed by the plane mirror 7, which is not described in detail herein.

The traditional rotary scanning based on the ball lens 6 often needs to be polished into the ball lens 6, so that lateral light is emitted, a certain failure proportion exists in the polishing manufacturing process, raw materials such as optical fibers and the like are wasted, and the rejection rate is high and the cost is wasted; at the same time, the hemispherical lens 6 needs to accurately calibrate the light beam, the light hole is drilled by aiming at the surgical mill, the process needs to be completed in a limited space, and the calibration difficulty is extremely high.
In the implementation mode, the adopted mode of the ball lens 6 and the plane mirror 21 is that the plane mirror 21 with the millimeter-sized size is far larger than the polished surface with the micrometer-sized size in size, and the debugging difficulty is greatly reduced.
The plane mirror 21 and the grinding and drilling optical port of the implementation mode adopt an integrated design (namely a fixed integrated design and participate in rotation together), the optical fiber ball lens 6 does not participate in rotation, vibration of the plane mirror 21 and grinding and drilling are the same in vibration source, a homologous rotation mechanical signal separation strategy can be utilized to sequentially separate the vibration sources in the mixed signal, and imaging quality reduction caused by vibration interference can be effectively reduced.
In this implementation manner, the outer surface of the grinding and drilling ball head is provided with a plurality of protrusions, the protrusion structure of the protrusions is the same as that of the grinding and drilling ball head in the existing scheme, no further limitation is made here, and the grinding and drilling ball head is realized by directly adopting the existing scheme by a person skilled in the art, so that the details are not repeated here.
