Embodiment two
Be different from the soft endoscope 1 among the embodiment one, present embodiment two provides the adjustable endoscope of a kind of soft or hard 2, as shown in Figure 4.Figure 5 shows that along the cutaway view of B-B straight line among Fig. 4.
In conjunction with Fig. 4 and shown in Figure 5, the endoscope 2 that this soft or hard is adjustable comprises: the body 20 with instrument channel pipe 11, illumination channel pipe 12, intake tunnel pipe 13, drawing silk passage 14 and backwater channel pipe 17.
Backwater channel pipe 17 is used for waste water discharges, and it comprises two ends, and wherein the camera lens of the adjustable endoscope 2 of an end and soft or hard is concordant or slightly be shorter than camera lens (i.e. assurance does not affect the camera lens visual field), this end is used for entering human body, also claim the inner, the other end relative with this inner is the outer end, is used for placing outside the human body.
Body 20 has the inner that is suitable for placing in the human body, with the outer end that is suitable for outside the human body.Except body 20, as shown in Figure 6, this soft or hard is adjustable, and endoscope 2 also comprises: the drawing silk 18 that is suitable for placing described drawing silk passage 14, one end of this drawing silk 18 and the inner of body 20 are fixed, namely relative with the position of camera lens fixing, thereby this end also claims stiff end, and the other end relative with this end is free end; Particularly, this drawing silk 18 comprises at least two one metal wires 181,182 and be nested in a plurality of mobiles 183 on the tinsel 182.
Below then introduce this endoscope 2 and realize the adjustable principle of soft or hard:
As shown in Figure 6, under the normal condition, a plurality of mobiles 183 disperse to be nested on the tinsel 182.In other words, a plurality of mobiles 183 for example are spheroid, are not fixedly connected with tinsel 182, can be along the spacing between the tinsel 182 slip change adjacent activities bodies 183.
Among the embodiment, the tube wall close contact of a plurality of mobiles 183 and drawing silk passage 14 is not with the tension of tinsel 182, loosen and change the position of its relative drawing silk passage 14.The tube wall of this drawing silk passage 14 has elasticity, but is pulled fold in the situation at tinsel 182, loosens in the situation and can unfold.
When endoscope 2 need enter human body, this drawing silk 18 needed so that endoscope 2 becomes rigid endoscope.Particularly, as shown in Figure 7, after tinsel 182 is pulled from free end, because the existence of stiff end, these a plurality of mobiles 183 are pressed together body 20, at least its head (being used for entering human body parts) hardening is so that this endoscope 2 is become rigid endoscope.
After entering human body, as shown in Figure 8, loosen this tinsel 182, be not close contact between the piecemeal activity body 183, drawing silk 18 is so that endoscope 2 becomes soft endoscope.Because camera lens is relative fixing with body 20 inner end positions, and the stiff end of the inner of body 20 and drawing silk 18 is fixed, at this moment, during from free end tractive tinsel 181, camera lens can rotate in the certain angle scope.
Be understandable that, adjustable for the soft or hard that realizes endoscope, be nested in a plurality of spheroids 183 on the tinsel 182 except sphere, can also be for any other shape, for example square, regular shape not even.
Can find out that the endoscope that above-mentioned soft or hard is adjustable can avoid the setting of sheath pipe with respect to the soft endoscope 1 of embodiment one, in other words, can increase the diameter of apparatus channel 11, satisfy the operation demand of different department.Among the embodiment, the diameter range of this instrument channel pipe 11 is 1-2mm.
