Description
Technical Field
The invention relates to a medical shadowless lamp with a variable illumination area and a using method thereof, belonging to the field of medical instruments.
Background
Surgical shadowless lamps are used to illuminate the surgical site for optimal viewing of small, low contrast objects at various depths in the incision and body cavity. Because the head, hands and instruments of the operator can cause interference shadows to the surgical site, the surgical shadowless lamp should be designed to eliminate the shadows as much as possible and minimize color distortion. The shadowless lamp cannot be 'shadowless', and only reduces the shadow so that the shadow is not obvious. The shadow is formed by the light irradiating the object. The shadowless lamp arranges the lamps with high luminous intensity into a circle on the lamp panel to form a large-area light source. Thus, the light can be irradiated on the operating table from different angles, the operation field is ensured to have enough brightness, and meanwhile, the obvious shadow is not generated, so the shadowless lamp is called as a shadowless lamp.
In clinical use, as the shadowless lamp is arranged above the operator, the head and the upper part of the trunk of the operator are positioned between the shadowless lamp and the patient, certain shadow is inevitably generated, and in most cases, the shadow is generated by the shielding of the head, the closer the head to the shadowless lamp is, the larger the shadow is, the farther the head is from the shadowless lamp is, the smaller the shadow is, but the corresponding light rays are scattered, and the definition is poor. Except for surgical instruments, the doctor usually does not allow other objects to be touched in the operation process, so that the nontoxic state of the hands is guaranteed, and infection is avoided. However, in clinical practice, the shadowless lamp needs to be moved and rotated correspondingly due to different operation postures or operation angles, and it is difficult for an assistant to achieve the psychological expectation of a main doctor if the assistant is used for operation. The operation is usually performed by wrist-hanging, but many young doctors or doctors with poor physical condition can shake hands due to lack of experience, tension, fatigue, hypoglycemia and the like, which is very unfavorable for the operation, and even medical accidents can happen in serious cases.
Disclosure of Invention
According to the defects in the prior art, the technical problems to be solved by the invention are as follows: the medical shadowless lamp with the variable illumination area and the use method of the medical shadowless lamp have the advantages that the illumination area can be adjusted adaptively according to the operation position of a patient, the illumination effect is better, operation personnel do not need to operate with hands when adjusting illumination, the pollution of the hands is avoided, the hands of an operator are supported by supports, the operation of wrist suspension is not needed, the occurrence of hand shaking is avoided, and the operation effect is guaranteed.
The medical shadowless lamp with the variable illumination area comprises two sliding rods which are arranged in parallel, the end parts of the two sliding rods are respectively and fixedly connected with an operating bed, the sliding rods are respectively provided with two sliding sleeves, a left shelf and a right shelf are respectively fixed on the sliding sleeves on the same side, and a plurality of adjusting units are respectively arranged below the left shelf and the right shelf;
