Background technology
Microendoscopic minimally invasive spinal surgery operation technique, microscopy endoscopic mirror system used mainly contains: MED
[1,2]and METRx
[3,4]endoscope system etc.But, there is many shortcomings in endoscope system used at present, as the working column of MED system, its upper/lower terminal opening inside diameter size is the same, its surface is with ring for fixing, ring for fixing is oversize etc. with upper part, thus during the microscopy endoscopic mirror system causing application current, and the patient visual field is by the shortcoming such as stopping obviously and the simple operation of operating theater instruments is poor.
Be described for existing MED endoscope system (hereinafter referred to as MED system) below.MED system is made up of MED working column, MED fixing stand for endoscope and endoscope.MED working column is circular hollow metallic conduit, and internal diameter of the pipeline is not expansible and its upper end open is the same with the internal diameter size of lower ending opening, and conventional internal diameter is 18mm.There is a ring for fixing on MED working column surface, MED working column is divided into top and bottom two parts, because ring for fixing and the fixed handle adhered on it can not enter in operative incision, therefore, the length of MED working column end portion is effective working column length, and upper part is only used for fixing MED fixing stand for endoscope.When carrying out operation technique in MED working column, except with except endoscope, patient often need detect by an unaided eye operative region.So, 3 factors affect the degree that the simple operation of the operating theater instruments of MED system and the patient visual field stop below: 1, the longitudinal axis angulation size of the operation technique apparatus such as rongeur and MED working column.Angulation its simple operation larger is higher, and the degree stopped the patient visual field is less, and 2, the size of endoscope tail end distance MED working column upper end open center of circle distance in the horizontal and vertical directions.In horizontal direction, distance is larger, and the distance in vertical direction is less, and its simple operation is higher, stops that degree is less to the patient visual field.3, the size of MED working column total length.Under the prerequisite that effective working column length is identical, MED working column total length is less, then its simple operation is higher, and the degree stopped the patient visual field is less.
According to above-mentioned 3 influence factors, there is following shortcoming in MED system: one, the internal diameter of its upper end open of MED working column is too small.Upper end open internal diameter is too small, the increase of operation technique apparatus and MED working column longitudinal axis angulation can be limited, also can limit levels Wei Shang endoscope tail end and MED working column upper end open distance of center circle from increase, thus reduce the convenience of surgical instrument operation and hinder patient to the observation of operative region.Two, the ring for fixing on MED working column surface is too wide, and ring for fixing is long with upper part.Ring for fixing is too wide, and the lower opening of the endoscope's slot in meeting shutoff MED fixing stand for endoscope, hinders endoscope's plug to move down, and causes endoscope's tail end in vertical direction large apart from the distance change in the MED working column upper end open center of circle; Ring for fixing is long with upper part, and making, when identical effective working column length, can increase the total length of MED working column.Three, endoscope inserts in MED working column.When performing the operation with MED working column, endoscope lens need be inserted in MED working column, because the sectional area of MED working column itself is limited, can reduce effective operation technique space like this, also can hinder the observation to surgical field of view.Four, MED fixing stand for endoscope is too high.Current MED fixing stand for endoscope side is seen L-shaped, its vertical portion branch increases the height of MED fixing stand for endoscope, cause MED working column upper part long, under the prerequisite of the effective working column of equal length, the total length of MED working column can be increased; Also can cause in vertical direction, endoscope's tail end becomes large apart from the distance in the MED working column upper end open center of circle simultaneously, thus affects the simple operation of operating theater instruments and hinder patient to the observation of operative region.
