Description

Medical high-resolution optical imaging probe

Technical Field

The utility model relates to a medical treatment optical imaging probe field especially relates to a medical treatment is with high resolution optical imaging probe.

Background

In clinical medicine, in order to make an accurate diagnosis of a lesion site, it is often necessary to take out a part of a lesion tissue from a patient body by means of cutting, clamping, or puncturing, and the like, to perform procedures such as fixing, embedding, sectioning, staining, and the like, to prepare a section, and to make a pathological diagnosis by observing under a microscope. This type of examination is called biopsy. Biopsy provides important basis for the diagnosis, treatment and prognosis judgment of clinicians. However, biopsy is an invasive examination method, cannot be used as a conventional screening means, and has a complicated process and a long result time. In addition, biopsy has a certain miss rate due to the limited location available for sampling. In recent years, advanced optical image detection means such as Optical Coherence Tomography (OCT) and confocal imaging have been rapidly developed, and resolution close to that of pathological examination has been obtained. The optical imaging detection method does not need to cut or specially process a tissue sample, and can noninvasively acquire a high-resolution image of in-vivo tissue in real time, so that a doctor is helped to quickly and accurately acquire a diagnosis basis, unnecessary biopsy is reduced, or the biopsy accuracy is improved, and the optical imaging detection method has great clinical application value.

The existing patent probe has micron-sized high resolution, and cell-level imaging is obtained in living tissues for the first time. The probe can be applied to gynecological examination, and can also be applied to examination of all body epidermal or mucosal tissues, such as skin, oral cavity and the like, which can be touched by the probe. In practice, in order to avoid possible cross infection among patients, the protection method commonly used at present is to cover a thin disposable transparent latex protective sleeve outside the probe for isolation, and the thin disposable transparent latex protective sleeve is replaced once every patient is done. However, there are certain problems: the presence of a protective sheath can affect the quality of the image,

there are problems with the use of such a protective sheath: firstly, in order to not influence the imaging quality too much, the protective sleeve is very thin and has certain damage risk; secondly, even if the protective sleeve is thin, the latex material is difficult to be completely transparent, and still has some influence on the imaging quality, which shows that the transverse resolution is obviously reduced, and the reduction degree is directly related to the thickness of the protective sleeve; thirdly, two reflecting surfaces are added to the protective sleeve, each added reflecting surface can introduce some stray light (noise), although the stray light introduced by the reflecting surfaces can be reduced by smearing a coupling agent, the stray light cannot be completely eliminated, in addition, the probe and the protective sleeve are difficult to ensure to be completely contacted well in actual use, and still a larger chance of seeing bright stray light reflection influences the observation of sample tissues. In order to solve the problem, the patent of conveniently disassembling the probe tube and the probe seat is provided, so that the probe tube and the probe seat are convenient to clean and replace, cross infection among patients during examination is avoided, and the problem of reducing imaging quality by using an additional probe sleeve is avoided.

when the fixing is needed, the push button is pulled by hand to move towards the probe seat, the connecting rod and the sliding block are driven to simultaneously move towards the probe seat, and the buffer spring is extruded, so that the sliding block is completely positioned in the first channel; move the locating piece towards the spacing groove of No. two connection pads, the spacing block shape of three locating piece both sides is different, so can only match with the spacing groove that corresponds, after the matching is accomplished, the locating piece passes in the spacing groove removes circular channel, later rotate the probe pipe, drive the locating piece and keep away from the one end movement of spacing groove towards the arc logical groove, after removing the tip, loosen and promote the knob, under buffer spring's elasticity, slider and locating piece plug-in connection realize the fixed of No. two connection pads of locating piece. Because the narrower part in locating piece center matches with the logical groove size of arc, so after the location is accomplished, the locating piece can not the lateral sliding, because the fixed of slider for the locating piece can not slide in circular channel, improves the stability of location. The disassembly is needed to be carried out in the reverse direction.

Because the limiting blocks on two sides of the three positioning blocks are different in shape, the angle between the second connecting disc and the probe tube when the second connecting disc and the probe tube are replaced each time is certain, and subsequent observation cannot be influenced. And the installation is dismantled simply, can not improve the formation of image degree of difficulty.
