Abstract

The invention relates to an operating lamp as well as a surgery field facula adjusting device and method of the operating lamp. The operating lamp comprises a lamp holder, multiple lighting units and the surgery field facula adjusting device, wherein the multiple lighting units are fixed on the lamp holder, the surgery field facula adjusting device comprises a facula adjusting control unit, a facula adjusting signal input unit and a drive unit; the facula adjusting signal input unit receives a facula adjusting signal input by an operator, and the facula adjusting control unit is used for converting the facula adjusting signal into a brightness control signal corresponding to each lighting unit; and the drive unit outputs a driving signal corresponding to the brightness control signal so as to drive the corresponding lighting unit. The operating lamp provided by the invention is adopted to realize the adjustment on the size, shape and the like of the surgery field facula through controlling the brightness of lighting units, thus doctors can conveniently adjust a surgery field required facula according to the operation condition.

Description

Technical field [0001] The invention relates to a surgical lamp and a device and method for adjusting the spot of an operation field, in particular to a surgical lamp that can adjust the spot according to a surgical incision, and a device and method for adjusting the spot of the operation field. Background technique [0002] Surgical lights (also called shadowless lights) are essential lighting elements in operating rooms. At present, the general operation lamp is composed of one or more lamp caps, each lamp cap contains multiple light-emitting elements and light-concentrating elements, and usually forms a fixed circular spot in the surgical field area to illuminate the surgical incision. Normally, in most types of surgery, the surgical incision is long or oval, and surgical instruments such as retractors and hemostatic forceps need to be placed around the surgical incision, especially on both sides of the incision. If the fixed spot is too small , You need multiple surgical lig...
