Description
Technical field
The invention belongs to surgery Minimally Invasive Surgery instrument field, specifically, invent a kind of new microscopy endoscopic mirror system, can effectively improve current microscopy endoscopic mirror system exists the patient visual field to be subject to endoscope's tail end to stop and the shortcomings such as convenience with operation technique apparatus is poor make microscopy endoscopic mirror system can meet better the needs of clinical position.
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 are many shortcomings in endoscope system used at present, as the working column of MED system, its upper/lower terminal opening internal diameter size is the same, its surface is with ring for fixing, the above part of ring for fixing is oversize etc., thereby causes while applying current microscopy endoscopic mirror system, and the patient visual field is stopped obviously and the poor shortcoming of simple operation of operating theater instruments.
The existing MED endoscope system (hereinafter to be referred as MED system) of take below describes as example.MED system is comprised of MED working column, MED fixing stand for endoscope and endoscope.MED working column is circular hollow metal pipeline, and internal diameter of the pipeline internal diameter size not expansible and its upper end open and lower ending opening is the same, 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 that adheres 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.While carrying out operation technique in MED working column, outside Chu Yong endoscope, patient's operative region that often need detect by an unaided eye.So, 3 factors below affect the simple operation of operating theater instruments of MED system and the degree that the patient visual field stops: 1, the longitudinal axis angulation size of the operation technique apparatus such as rongeur and MED working column.Larger its simple operation of angulation is just higher, and the degree that the patient visual field is stopped is just less, 2, endoscope's tail end apart from the MED working column upper end open center of circle size of 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 just higher, and the patient visual field is stopped to degree is just less.3, the size of MED working column total length.Under the prerequisite that effectively working column length is identical, MED working column total length is less, and its simple operation is just higher, and the degree that the patient visual field is stopped is just 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, can limit the increase of operation technique apparatus and MED working column longitudinal axis angulation, also can limit levels Wei Shang endoscope's tail end and MED working column upper end open distance of center circle from increase, thereby reduce the convenience of operating theater instruments operation and hinder the observation of patient to operative region.Two, the ring for fixing on MED working column surface is too wide, and the above part of ring for fixing is long.Ring for fixing is too wide, can shutoff the lower opening of endoscope's slot in MED fixing stand for endoscope, hinder endoscope's plug to move down, cause endoscope's tail end in vertical direction to become large apart from the distance in the MED working column upper end open center of circle; The above part of ring for fixing is long, and making, the in the situation that of identical effective working column length, can increase the total length of MED working column.Three, endoscope inserts in MED working column.While performing the operation with MED working column, endoscope lens need be inserted in MED working column, limited because of the sectional area of MED working column itself, can reduce so effective operation technique space, 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, can increase the total length of MED working column; 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, thereby affects the simple operation of operating theater instruments and hinder the observation of patient to operative region.
