Description
Technical Field
The invention particularly relates to the technical field of medical equipment, in particular to an operating table and a backboard radian adjusting method.
Background
The operating bed is one of the basic equipment of the operating room and plays an important role in the surgical equipment. Along with the development of surgical operation technology and the improvement of machining capability and design and manufacturing level, multi-functionalization and specialization are an important direction of the development of an operation table. In the past, medical staff understand the position of an eye surgery to achieve a supine position with the head and the face in a horizontal position. Therefore, the used operation bed can meet the requirement as long as the operation bed is provided with the height adjustment of the headrest and the height adjustment of the bed body. So the multifunctional surgical bed commonly used in surgery has been commonly used in ophthalmology. However, it was found that the height adjustment range of the surgical bed did not meet the requirements of the ophthalmic surgery, the planar headrest, which was as wide as the bed body, did not fix the head of the patient well, and the operator had difficulty stretching his legs while sitting on the surgery, which affected the operation. Thus, an ophthalmic operation table with a simple design of a horizontal linear type operation table and a pillow holder has been developed.
With the continuous improvement of the requirements of people on the quality of life and the rapid development of the ophthalmic clinical medical technology, the surgical indications are continuously increased, and the therapeutic quantity of the ophthalmic surgery is improved year by year. Ophthalmic surgery is evolving towards more minimally invasive surgery, and surgeons have higher demands on the handling fineness and stability. On the other hand, ophthalmic surgery is peculiar in that, except for children and adults who cannot cooperate with the surgery, local anesthesia is the first choice for the internal eye surgery and most of the external eye surgery, so local anesthesia is the main anesthesia mode of ophthalmic surgery, and most patients cooperate with the surgery quietly in a conscious state. Simple operations under ocular surface anesthesia such as cataract and the like need to be matched with the fixation of the operation eyes in the operation of patients.
The ophthalmic surgery time is relatively short, the continuous table surgery is more, the surgery turnover is quick, and most of surgical patients adopt wheelchairs for transportation. The elderly patients with hearing and vision disorder often have slow movement, and are difficult to get on and off the operating bed, and easily cause injuries such as falling down and falling down. In high-flow continuous operation, the operation physical power consumption of helping a patient to go on an operation table before an operation, arranging a body position and helping the patient to go off the operation table after the operation is finished is large. In addition, senile kyphosis deformities of varying degrees are common in clinic. Patients with such back bulges are difficult to lie on their backs on a horizontally linear operating table. Clinically, various materials such as self-made gaskets, body position gaskets and the like are used for local filling and heightening, so that the time for placing the body position is increased, the stability of the arranged supine position is poor, the head position is difficult to fix stably, difficulties and risks are brought to operation, and falling down of the bed is prevented. In addition, the pressure at the bone protruding part of the patient is high, so that the head position is forced to be kept horizontal, and the risk of cervical vertebra overstretching damage exists. The foreign patient operation adopts the head-foot high position or the inclined operation microscope eyepiece angle to perform the operation, thereby increasing the operation risk. Patients with severe spinal deformity often cannot perform surgery because of the positioned body position, too high head position, and out of the focusing range of the microscope.
