When posterior approach was performed the operation, because lumbar vertebra has the physiological lordosis, prone position operation exposes often owed satisfied at lumbar vertebra.

Therefore the structure of operation table must be further improved, the requirement of operation could be adapted to better.

The purpose of this utility model is that a kind of use through the rear path surgical bed will be provided more, and it can overcome above-mentioned shortcoming.

The purpose of this utility model is to realize like this, breast backing plate thigh backing plate, the shank backing plate all uses bearing pin hinged, and elongated slot all is set on the backing plate, is convenient to align its angle of inclination and position, buttocks backing plate and sufficient backing plate all combine with bearing pin and connecting rod, each is connected with thigh, shank backing plate respectively, and the other end of breast backing plate is equipped with slide bolt and connecting rod, and is hinged with bearing pin, connecting rod is hinged with hook plate again, elastic cushion all is housed on each backing plate contacts with human body.

This structure adopts elongated slot and bearing pin hinged, aligns easyly, during operation, can adopt the appearance pad of squatting, and the appearance of lying on the back pad etc. can adapt with various surgical operations.

Fig. 2 is that general surgery bed cervical vertebra is through posterior approach surgery location sketch map.

Fig. 3 is the head cervical vertebra, and last thoracic vertebra is through posterior approach operation position sketch map.

Fig. 4 is the surgery location sketch map of lying on the back.

Now in conjunction with the accompanying drawings to using structure to be described in detail through the rear path surgical bed more.

By Fig. 1, breast backing plate (1) is mutually hinged with bearing pin (10) with thigh backing plate (2), thigh backing plate (2) flexibly connects by bearing pin (20) and shank backing plate (3) again, can rotate suitable angle, when making patient prostrate, can fully bend hip, go down on one's knees, make behind the waist protruding, help waist posterior approach surgical exposure, thigh backing plate (2) one ends have elongated slot (21), bearing pin (20) can move in elongated slot (21), aligns it and connects length, adapts to thigh length, buttocks backing plate (4) is hinged with connecting rod (5), connecting rod (5) one ends have elongated slot (22), and bearing pin (23) is contained in and utilizes the elongated slot (24) of elongated slot (22) and thigh backing plate (2) can align its relative distance in the elongated slot (22).

Foot backing plate (6) is a rectangular shaped, end has elongated slot (25) and connecting rod (7), right-hand member is hinged with bearing pin (26), the left end of connecting rod (7) connects in the elongated slot (30) of shank backing plate (3) one ends with bearing pin (31) again, utilize the structure of buttocks backing plate (4) and sufficient backing plate (6), patient can be adopted squat posture on operation table, make the cervical region can be protruding later on, surgical exposure be satisfied, and operating field is in the extreme higher position, it is just less to lose blood in the operation process, guarantee the stable of operation, be difficult for changing or gliding that (Fig. 3) partly body weight is born by buttocks backing plate (4) and shank backing plate (3), alleviate the chest burden, make breathing normally well-balanced.Breast backing plate (1) left end is connected with a slide bolt (16), its bearing pin (10) is contained in the elongated slot (11) of connecting rod (15), hook plate (8) bends to arc, one end and connecting rod (15) are hinged, there is volume cushion (14) hook plate (8) inboard, breast cushion (13) is housed on the breast backing plate (1), thigh backing plate (2) one sides are equipped with elastic cushion (28), cushion (29) is housed on the shank backing plate (3), cushion (27) is equipped with in foot backing plate (6) inboard, there is cushion (17) buttocks backing plate (4) inboard, and these cushions can be bonding or be fixed with velcro.
