Description

Medical shadowless lamp of low level hand touch operation exempts from

Technical Field

The invention relates to a low-position hand-touch-free operation medical shadowless lamp, and belongs to the field of medical appliances.

Background

Surgical shadowless lamps are used to illuminate the surgical site to optimally view small, low contrast objects at different depths in the incision and body cavity. Since the operator's head, hands and instruments may cause disturbing shadows to the surgical site, the surgical shadowless lamp should be designed to minimize shadows and minimize color distortion. The shadowless lamp is not actually "shadowless" and it merely reduces the ghost so that it is not obvious. The shadow is formed by illuminating the object. The shadowless lamp arranges the lamps with high luminous intensity on the lamp panel into a circle to form a large-area light source. Therefore, the light can be irradiated onto the operating table from different angles, so that the operating field of view is ensured to have enough brightness, and obvious shadow can not be generated, and the operating table is called as a shadowless lamp.

In clinical use, as the shadowless lamp is above the operator, the upper parts of the head and the trunk of the operator are positioned between the shadowless lamp and the patient, a certain shadow is inevitably generated, and in most cases, the shadow is generated by shielding the head, the shadow is larger as the head is close to the shadowless lamp, the shadow is smaller as the head is far from the shadowless lamp, but the corresponding light is scattered, so that the definition is poor. In the operation process, except surgical instruments, a doctor of a main knife is generally not allowed to touch other objects so as to ensure the non-toxic state of the two hands and avoid infection. However, in clinic, due to different operation postures or operation angles, the shadowless lamp needs to be correspondingly moved and rotated, and if an assistant operates the shadowless lamp, psychological expectation of a doctor of the main knife is difficult to achieve. In the operation, the wrist hanging operation is usually carried out, but for many young doctors or doctors with poor physical condition, the hand tremble can be caused due to insufficient experience, tension, fatigue, hypoglycemia and other reasons, the operation is very unfavorable, and even medical accidents can occur in serious cases.
