Abstract
The utility model relates to a cervical vertebra rear operation head support which adopts the structure that a U-shaped connection support rod connected with an operation table, a horizontal sliding connection rod and a skull traction rod are connected by two adjustment fastening bolts, wherein a head panel is welded on a lifting sliding rod connected with the horizontal sliding connection rod by two sliding fastening sleeve barrels, the adjustment fastening bolts are welded between the two sliding fastening sleeve barrels and fastening slots are respectively engraved on one side of the lifting sliding rod and one side of the horizontal sliding rod. The panel can be adjusted forwards, backwards, upwards and downwards and the tilt angle of the panel can also be adjusted so as to enable the cervical vertebra to be fully flexed and stretched. The utility model has the advantages of clear visual field at the time of operation and easy operation, and can furthest reduce damage to spinal cords and nerves.
Description
Medical apparatus and instruments is used in cervical posterior approach especially.
At present, existing technology is that the used headstock of cervical posterior approach is the general anesthesia headstock, this headstock can not before and after and adjust downwards and move, only can adjust upward, in the operation process, before and after can not reaching downwards, adjust, thereby can not make abundant flexing of incidence and full extension according to patient's neck length, surgical field of view is little, lamina of cervical vertebra is difficult for opening, easily Spinal Cord, nerve.Though have the neurosurgery headstock to use when cervical posterior approach, this headstock costs an arm and a leg, complicated operation, not that to aim at cervical operation used, be mainly used in craniocerebral operations, for this reason, need the new headstock of design.
For solving the shortcoming and defect of above-mentioned existence, need a kind of cervical posterior approach headstock that can reach the front and back adjustment up and down of design, make cervical vertebra fully flexing and stretching, extension, be convenient to operation technique, reduce the chance of spinal cord and nerve injury.
Art designs scheme of the present utility model is connected " U " shape and connects support bar with operation table, horizontal slip connecting rod and skull traction bar connect by two adjustment fastening bolts, the head panel is welded on the lifting sliding bar, lifting sliding bar and horizontal slip connecting rod are connected, are welded with the adjustment fastening bolt between two fastening sleeves of slip by two fastening sleeves that slide, and a side of lifting sliding bar and horizontal slide rod is carved with binding groove.
Design of the present utility model can before and after and adjust panel up and down, and can adjust the panel inclination angle, so that abundant flexing of cervical vertebra and stretching, extension, panel and patient's forehead and cheekbone portion are combined closely, operation seasonal disease department of human head and neck is stable, surgical field of view is clear, lamina of cervical vertebra overlapping expansible, be easy to operation technique, damage chance, the facial field of load of while that can reduce spinal cord and nerve to greatest extent are big, reduced the chance of facial pressure ulcer, the patient that skull traction is arranged, can be connected with the traction hammer by skull traction bar top sheave, and can adjust lead.

Embodiment
The concrete structure of this utility model in conjunction with the accompanying drawings 1 with accompanying drawing 2 auspicious state as follows: " U " shape is connected support bar 1 inserts on the plate jack of operation table, horizontal slip connecting rod 7 is connected support bar 1 connection by adjusting fastening bolt 2 with " U " shape, skull traction bar and pulley 9 are connected with horizontal slip connecting rod 7 by adjusting fastening bolt 8, panel 3 is welded on the lifting sliding bar 4, slide fastening sleeve 5 and the fastening sleeve 6 of horizontal slip of lifting is connected by adjusting fastening bolt 10, lifting sliding bar 4 is inserted in lifting and slides on the fastening sleeve 5, the fastening sleeve 6 of horizontal slip is enclosed within on the horizontal slip connecting rod 7, patient is prostrate on operation table, and forehead and cheekbone are deployed on panel 3.
The embodiment specific implementation process is following, patient is prostrate fits perfectly on panel 3 in forehead on the operation table and cheekbone portion, by adjusting the fastening sleeve 6 of horizontal slip panel 3 is moved forward and backward, so that cervical vertebra is fully stretched; Panel 3 is moved up and down so that make the abundant flexing of cervical vertebra by adjusting the lifting fastening sleeve 5 that slides; By adjusting the gradient that fastening bolt 10 is regulated panel 3, forehead and cheekbone portion and panel 3 can reach combines closely again.When need changing the position of panel 3 in the operation process also scalable adjust fastening bolt 2 and make panel 3 slight slopes, reach suitable angle.When in the art skull traction being arranged, draught line is connected with the traction hammer by the pulley 9 on the skull traction bar, can adjust the angle that fastening bolt 8 changes skull traction bar 9 by regulating, and reaches ideal lead, as when not having traction, can remove skull traction bars 9 by adjusting fastening bolt 8.
