Multi-body-position neurosurgery operating table

Technical Field

The invention relates to the field of operating tables, in particular to a multi-body-position neurosurgery operating table.

Background

Neurosurgery is a discipline for treating diseases of brain, spinal cord and peripheral nervous system by using a surgical method and taking an operation as a main treatment means, is a discipline of high, essence and pointedness in the current medical field, and is generally recognized as the field with the highest medical position; the operations of tumor, blood vessel, disc discectomy and the like in neurosurgery are microsurgery operations performed under a large-scale operation microscope, the operations are extremely fine, complex, dangerous and time-consuming, not only medical staff are required to have better technique and physical strength, but also great challenges are brought to patients; in the operation process, patients are in an anesthesia state, and in the anesthesia state, the patients are in a passive lying position, but a large neurosurgery operation usually needs several hours or even more than ten hours, so that the patients need to face a very troublesome problem, namely pressure injury.

Pressure injury is localized damage to the skin or underlying tissues, usually occurring in the bony prominences or in areas of prolonged compression, and can be manifested by local tissue damage but complete or open ulceration of the epidermis, with pain, and most of the pressure injuries suffered by patients during surgery exhibit symptoms of injury 1-3 days after surgery; during the operation, the pressure injury is positively correlated with the operation time, the patient can have irreversible injury after keeping an operation position for more than 2 hours, the occurrence rate of the pressure injury is increased by 33 percent every 30 minutes, and the pressure injury can be inevitably generated after the pressure injury lasts for 4 hours; under the prior art condition, for the prevention patient pressure nature damage appears, need adopt multiple silica gel cushion to carry out static bedding to patient different positions, cushion kind quantity is tens of even, not only complex operation, and the pressure nature damage of different degrees can appear equally in cushion pressure cushion for a long time, consequently, research and development one kind is applied to the neurosurgery and can avoid the patient to appear pressure nature damage's operation table has obvious meaning.

the head fixing mechanism is arranged at the front end of the bedstead and forms a moving pair, the outer side of the headrest is coated with a soft silica gel surface and is arranged at the middle position of the upper side of the sliding table, the right side of the left splint is of a cambered surface structure coated with the soft silica gel, the right splint and the left splint are in a bilaterally symmetrical structure, the left splint and the right splint are arranged at two sides of the headrest and form a moving pair with the sliding table, and the hand wheel can control the movement of the left splint and the right splint so as to fix and release the head of a patient;

the supporting unit is characterized in that the outer side of a square body is of a square structure, a stepped square hole is formed in the supporting unit, a motor is fixedly installed in the square body, an internal thread is arranged in an output shaft of the motor, an ejector rod is installed in the square body and forms a moving pair, a threaded rod at the lower end of the ejector rod and the internal thread of the output shaft of the motor are matched to form a thread pair, a top cap is installed at the upper end of the ejector rod, a pressure sensor is arranged between the ejector rod and the top cap, a swinging plate is rotatably connected with the top cap through a cross shaft, four silica gel pads are fixedly connected to the upper side of the swinging plate, and a spring is installed between the swinging plate and the top cap.

2. The multi-posture neurosurgical operating bed according to claim 1, wherein: the upset action of left part body brace table, the brace table of the right part body and the sideslip action of sideslip brace table all can be controlled by the host computer according to the operation needs, and the support element array in each support zone can be carried out intelligent regulation by the host computer.

3. The multi-posture neurosurgical operating bed according to claim 1, wherein: five elastic-adjustable binding belts are arranged on the operating bed and are respectively used for fixing the chest, the left arm, the right arm, the thigh and the shank of the patient.

4. The multi-posture neurosurgical operating bed according to claim 1, wherein: the spring penetrates through a round hole in the center of the cross shaft and is arranged between the swinging plate and the top cap, so that the swinging plate can be always kept in a horizontal state in a natural state.

5. The multi-posture neurosurgical operating bed according to claim 1, wherein: the swinging plate, the cross shaft and the top cap form a Hooke hinge structure with two rotational degrees of freedom, and the silica gel pad on the upper side of the swinging plate can be turned over according to the contact angle with the body of a patient, so that the contact area with the patient is increased, and the pressure per unit area is reduced.

6. The multi-posture neurosurgical operating bed according to claim 1, wherein: the pressure sensor can monitor the supporting force of the silica gel pad on the body of the patient in real time, and the motor can drive the ejector rod to move up and down through the thread pair after rotation, so that the supporting force of the corresponding silica gel pad on the patient can be adjusted.

7. The multi-posture neurosurgical operating bed according to claim 1, wherein: each supporting area on the operating bed forms a relatively independent supporting system, and the mandrils which provide support for the patient in the same supporting area can move up and down to ensure that the supporting force of each mandrils is nearly the same, thereby avoiding the occurrence of the condition of overlarge local pressure.

8. The multi-posture neurosurgical operating bed according to claim 1, wherein: when the upper computer detects that the time for the patient to keep the same body position exceeds one hour, the support arrays in the support areas can actively relieve the pressure of the patient.
