[0003] When the surgical shadowless lamp is used in the operating room, it is necessary to rotate the joint parts. However, the shadowless lamps that are commonly used in the market today use a wire-to-insert structure, and the structure has dead ends. The wire is twisted, so the surgical shadowless lamp cannot rotate without limit

Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0031] Such as Figure 1-4 As shown, a conduction structure for a surgical shadowless lamp is connected between the lamp arm of the surgical shadowless lamp and the surgical shadowless lamp, and includes an upper conduction structure 100 and a lower conduction structure 200 that can rotate relative to 360°. The lower conduction structure The top of the 200 is inserted into the bottom of the upper conduction structure 100 , and the axes of the upper conduction struc...

The invention discloses an electrical conduction structure for an operating shadowless lamp. The electrical conduction structure is connected between a lamp arm of the operating shadowless lamp and the operating shadowless lamp, and comprises an upper electrical conduction structure and a lower electrical conduction structure, which can rotate 360 degrees relative to each other, wherein the top of the lower electrical conduction structure is inserted into the bottom of the upper electrical conduction structure; the axle centers of the upper and lower electrical conduction structures are collinear; the upper electrical conduction structure comprises a first bakelite part, a first negative electrical conductor core and a first positive electrical conductor core, and the axle centers of the first bakelite part, the first negative electrical conductor core and the first positive electrical conductor core are collinear; a groove is formed in the lower surface of the first bakelite part, a first positive through hole is formed in the axle center of the first bakelite part, and a first negative through hole is arranged in parallel with the axis. The electrical conduction structure has the beneficial effects that the shortcoming of dead angles during the use of the operating shadowless lamp with an electric wire inter-plugging structure in a hospital is overcome; the electrical conduction structure is arranged between rotating parts of the operating shadowless lamp, so that the operating shadowless lamp can limitlessly rotate 360 degrees; the electrical conduction structure is reasonable in design and compact in structure.
Description
technical field [0001] The invention relates to a conduction structure, in particular to a conduction structure of a surgical shadowless lamp. Background technique [0002] Surgical shadowless lights are used to illuminate surgical sites to best observe small, low-contrast objects at different depths in incisions and body cavities. Since the operator's head, hands and instruments may cause interference shadows on the surgical site, the surgical shadowless lamp should be designed to eliminate shadows as much as possible and minimize color distortion. [0003] When the surgical shadowless lamp is used in the operating room, it is necessary to rotate the joint parts. However, the shadowless lamps that are commonly used in the market today use a wire-to-insert structure, and the structure has dead ends. The wire is twisted, so the surgical shadowless lamp cannot rotate without limit. Contents of the invention [0004] In order to solve the above problems, the present inventi...
