DETAILED DESCRIPTION

[0021] In order to make the ordinary skilled in the art more clearly understand, the following combining with the drawings and examples to make further description of the utility model.

[0022] As Figures 1-4 , the utility model discloses a kind of visual lamina drill in single-channel double medium endoscopic surgery, including main body 1, channel pipe 2, mirror frame 3 and endoscope 4, the main body includes drill rod 11, handle 12 and positioning needle 13, drill rod is made of stainless steel upper section thin, lower section thick cylinder, drill rod lower section lower part is twist drill bit 111;Drill rod upper end is connected with handle, drill rod and handle are longitudinally provided through hole;Positioning needle is made of stainless steel, can be longitudinally through handle and drill rod;The channel pipe is provided with drill rod hole 21, detection hole 22 and fixed column 23, drill rod lower section is placed in drill rod hole;The mirror frame includes probe pipe 31, limit groove 32, fixed buckle 33 and water guide pipe 34, wherein probe pipe is placed in detection hole, and fixed buckle is installed on fixed column;The endoscope includes detection pipe 41, light mirror 42, signal hole 43 and positioning sheet 44, and is installed on mirror frame.

[0023] The utility model discloses a kind of visual lamina drill in single-channel double medium endoscopic surgery, using, by following steps implementation when using:

[0024] (I) preliminary positioning. Channel pipe 2 is opened by gradually expanding pipe and is fixed on the target point position on lamina through the muscle of lamina surface soft tissue and so on and is fixed on the target point position on lamina;

[0025] (II) accurate positioning. The lower end of drill rod 11 of main body 1 is placed on target through the drill rod hole 21 of channel pipe 2, handle 12 is sleeved on the top end of drill rod, positioning needle 13 is passed through the through hole of connecting rod 122 and drill rod, tip is to the target point position on lamina, using X-ray mirror observation guide, make the lower end tip of probe needle align the center point of the cutting part, using medical hammer slowly knock the upper end of positioning needle, make the lower end tip gradually pierce in the depth of the cutting part;This step is observed through X-ray mirror and the scale change of upper section of positioning needle, guarantee that the tip of positioning needle is accurately positioned;

[0026] (Three) blind drilling. Move the limiting card 113 on the drill rod to the scale line 112 area, the distance between the lower edge of the limiting card and the upper edge of the positioning cylinder is the cutting depth of the blind drilling, tighten the limiting card screw, and fix the limiting card on the drill rod to ensure that the blind drilling depth will not increase; at this time, the operator rotates the hand holding part 121 of the handle 12 to drive the twist drill 111 of the drill rod to rotate and cut the lamina until the limiting card touches the positioning cylinder, thus completing a blind drilling, and if further drilling of bone tissue is needed, the cycle can be used to reach the required depth;

[0027] (Four) install the spinal endoscope.
