Medical shadowless lamp with variable lighting area and using method thereof

Abstract

The invention relates to a medical shadowless lamp with a variable lighting area and a using method thereof, and belongs to the field of medical instruments. The medical shadowless lamp comprises twosliding rods which are arranged in parallel, the ends of the two sliding rods are fixedly connected with an operating bed respectively, two sliding sleeves are arranged on each sliding rod, a left shelf and a right shelf are fixed to the sliding sleeves on the same side respectively, and a plurality of adjusting units are arranged below the left shelf and the right shelf respectively. The lightingarea can be adaptively adjusted according to the surgery position of a patient, the lighting effect is better, an operator does not need to operate with hands when adjusting lighting, hand pollutionis avoided, the two hands of the operator are supported by supports, operation under wrist suspension is not needed, hand shaking is avoided, and the surgery effect is guaranteed.

Description

technical field [0001] The invention relates to a medical shadowless lamp with a variable illumination area and a method for using the same, belonging to the field of medical devices. 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. The shadowless lamp is actually not "shadowless", it just lightens the umbra so that the umbra is not obvious. Shadows are formed when light hits an object. The shadowless lamp arranges the lamps with high luminous intensity in a circle on the lamp panel to synthesize a large-area light source. In this way, the light can be irradiated onto the operating table from different angles, whic...

Problems solved by technology

However, due to different operating postures or operating angles in clinical practice, the shadowless lamp needs to be moved and rotated accordingly. It is difficult to meet the psychological expectations of the chief surgeon if an assistant is used to operate it.

Surgical operations are usually carried out by hanging the wrist, but for many young doctors or doctors with poor physical conditions, due to lack of experience, nervousness, fatigue, or hypoglycemia, etc., the hands will shake, which is very unfavorable for the operation. even medical malpractice
