The invention belongs to the technical field of medical apparatuses and instruments and provides a nerve-blocking puncture catheter needle with an adjustable puncture head. The catheter needle mainly consists of a puncture catheter and a puncture needle core. During operation, the puncture needle core is sleeved by the puncture catheter, and the sharp end of the puncture needle core extends out of a port of the puncture catheter and has sharpness. Under the ultrasonic guidance, the sharp end of the puncture needle core can return to the puncture catheter through adjustment and control when the catheter is close to the target nerve, and the catheter needle loses the sharpness but still has toughness and can continue to penetrate the fascia tissue to be close to the nerve till the catheter needle touches the nerve. Due to the fact that a needle point returns back to the catheter and loses the sharpness, the nerve is not hurt, the catheter needle reaches a target position, the puncture needle core can be directly removed, and the puncture catheter is indwelt around the nerve for future anesthesia medicine application or anesthesia analgesia treatment and other applications.

A manufacturing method of a spectacle lens improving a manufacturing yield and a production efficiency is provided. The manufacturing method of the spectacle lens in which necessary information for a frame machining of a spectacle lens (progressive-power lens 20) including spectacle rim related information is obtained, and both surfaces of a convex surface and a concave surface are edge / polish machined from a spectacle lens blanks. When the convex surface or the concave surface is polish machined, and thereafter, the next surface is machined, the spectacle rim related information and layout information of the edge machining are obtained, and first provisional reference position marks 1 to 3 and second provisional reference position marks 4 to 6 guiding a geometrical horizontal reference and a geometrical perpendicular reference of the lens are inscribed at positions outside of an edge shape 111 as identification marks for the machined surface being polished as a provisional reference marking process, an optical layout is performed for the surface to be machined next based on these provisional reference position marks to perform a lens block to a lens machining tool.

The invention discloses a universal cellphone lens, and the lens comprises an objective lens assembly, a sleeve, a prims assembly, a housing assembly, an adjustment groove, and an ocular lens assembly. The sleeve comprises a first sleeve and a second sleeve, which are hinged to the outside of the housing assembly. The objective lens assembly and the ocular lens assembly are installed in the housing assembly, and the prism assembly is installed in the housing assembly. Moreover, the prism assembly is located between the objective lens assembly and the ocular lens assembly. The adjustment groove is disposed outside the housing assembly, and the interior of the first sleeve and the interior of the second sleeve are respectively provided with a sleeve trench, wherein the sleeve trenches cooperate with the adjustment groove for use. The ocular lens assembly is provided with a staple bolt. The objective lens assembly and the ocular lens assembly are enabled to move back and forth through the rotating of the first and second sleeves, and the distance between the ocular lens assembly and a cellphone lens can be changed, so as to adapt to cellphones with different brands. The lens is good in universality, and can be used for many cellphones, and there is no need of a dedicated lens even if a cellphone is replaced in future.

The invention discloses an image capture device, and relates to the technical field of images. The image capture device comprises a base, and a driving mechanism is arranged at the back of the base; and the output end of the driving mechanism is fixedly connected with a rotating shaft through a coupling, and the end, far away from the driving mechanism, of the rotating shaft penetrates through thebase, and is fixedly connected with a rotating table. According to the image capture device, through improvement of a camera device and a detection device, as well as cooperative application of the driving mechanism and the rotating shaft, the horizontal state of a camera body is regulated by adopting electric signals directly, and the situation that the camera body is in the non-horizontal stateand consequently the level degree of shot images is not high is avoided; the difficulty in camera operation is reduced, and meanwhile the definition of the camera and the protection degree of a camera lens can be properly regulated according to the actual conditions (the higher the protection degree of the camera lens is, the poorer the light rays of the camera lens is, and consequently the lowerthe definition of the camera shooting is.).

The invention relates to a full-automatic nail polishing machine which comprises a vibration disc feeder, a horizontal nail polishing machine tool body and a vertical nail polishing machine tool body, wherein a front panel is arranged on the vertical nail polishing machine tool body; an automatic nail arranging distributor, a transmission screw rod and a transmission motor are fixed on the front panel; the automatic nail arranging distributor is connected with a discharging port of the vibration disc feeder; a discharging port of the automatic nail arranging distributor is propped against the outer thread at one end of the transmission screw rod; a discharging port is formed in the other end of the transmission screw rod; a grinding wheel and a grinding wheel transmission motor are fixed on the horizontal nail polishing machine tool body; a polishing port is formed in the vertical nail polishing machine tool body and below the transmission screw rod; the polishing surface of the grinding wheel extends into the polishing port. The full-automatic nail polishing machine is convenient to operate, and during the operation, the nails to be polished are put in the vibration disc feeder and then starting is carried out on the polishing machine, so that the labor intensity of manual emptying and polishing is decreased, the polishing efficiency is improved, the harm from the dust to the operators is avoided, the approximately same length and shape of the polished nails are realized, and the polishing quality is improved.

A photosensitive assembly, comprising a filter film and a light sensing circuit, wherein the light sensing circuit receives an optical signal that penetrates through the filter film; the filter film comprises a liquid crystal structure, wherein the liquid crystal structure comprises liquid crystal, the liquid crystal constitutes a light portion and a light shielding portion of the filter film according to different liquid crystal deflection angles, and a light transmitting portion is spaced apart from the light shielding portion. In the present invention, by using liquid crystal as a material of the light shielding portion of the filter film, the rotation angle of liquid crystal can be changed according to requirements, an all-phase image can be obtained, and the captured range is larger. Moreover, the shape of the light shielding portion can be adjusted according to requirements, and the sharpness of an obtained picture can be adjusted, and an image can be acquired more flexibly.
