As a kind of embodiment of the present utility model, described fibrescope sleeve is fixed on handle.
Compared with prior art, the utlity model has following beneficial effect:
First, this utility model is by flexible fiberscope and fibrescope sleeve, the lens movable of flexible fiberscope is through the inner chamber of fibrescope sleeve, the tubular shaft inner chamber of knob and the inner chamber of claw beam sleeve, reach in the angular range that binding clip opens, make flexible fiberscope and binding clip all can surpass the angle rotation of 180 °, the light that flexible fiberscope the scatters surgical field of view that elastic separating plier struts of can going directly preferably, and after being transferred to outside transducer, the scene within the scope of the surgical field of view being illuminated shows, thereby obviously improve surgical field of view, effectively auxiliary cutting and separating, reduce surgical error and complication, avoid the important nerve of separated region, the damage of blood vessel and organ, particularly when closed with straight cuts closer, fully appear its remote organization, avoid secondary damage, improve success rate of operation,
The second, the camera lens of this utility model flexible fiberscope has the optical fiber minute surface with the axial angle at 45 ° of claw beam, has improved the visual scope of elastic separating plier, has realized all standing to operation field range.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of this utility model elastic separating plier;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is that the B portion of Fig. 1 is with the enlarged diagram of optical path direction.
The specific embodiment
As shown in Figure 1 to Figure 3, visual micro-wound surgical operation elastic separating plier of the present utility model, comprise handle 1, claw beam 3, claw beam sleeve 4, binding clip 5, flexible fiberscope 6, fibrescope sleeve 7 and the knob 2 for driving claw beam 3 to rotate, knob 2 has tubular shaft 2a, this knob 2 is connected between handle 1 and claw beam sleeve 4, wherein knob 2 movable buckles are on handle 1, one end of claw beam 3 is successively through being connected on handle 1 after the inner chamber of claw beam sleeve 4 and the tubular shaft inner chamber of knob 2, the other end is connected with the binding clip 5 being positioned at outside claw beam sleeve 4, handle 1 drives binding clip 5 opening and closing by claw beam 3, fibrescope sleeve 7 is fixed on handle 1 and is communicated with the tubular shaft of knob 2, the diameter of flexible fiberscope 6 is 3 to 5mm, its lens movable is through the inner chamber of fibrescope sleeve 7, the tubular shaft inner chamber of knob 2 and the inner chamber of claw beam sleeve 4, reach in the angular range that binding clip 5 opens, and the camera lens of this flexible fiberscope 6 has the optical fiber minute surface 6a with claw beam 3 axial angles at 45 °.
