Description
Technical field
The present invention relates to technical field of medical instruments, the snake bone of specifically a kind of endoscope.
Background technology
Endoscope is that one kind has concentrated traditional optical, ergonomics, precision optical machinery, hyundai electronicses, mathematics, software to be equal to
The detecting instrument of one.Using endoscope it can be seen that the lesion that X ray can not be shown, therefore it is highly useful to doctor.
Existing endoscope is all to pass through drawing and snake by built-in snake bone when angle of bend realizes head-bent deflecting
The method of the steel wire rope of bone connection makes what it bent.After existing snake bone is typically by pitch circle, some snake joints and snake bone before snake bone
Pitch circle rivets composition successively；Two arc wire-blocking boards are equipped with each snake joint, arc wire-blocking board is formed with snake joint inwall
For wearing the perforation of steel wire；At present, the line of centres phase of two rivets of the line of centres of two arc wire-blocking boards and snake joint
Mutually vertical, this, which causes to be distributed well in limited snake joint space, sets lighting fiber, image transmission optical fibre and pincers deferent.
In addition, existing snake cyrtosis degree is smaller, it is unfavorable for operation technique.
The content of the invention
It is an object of the invention to provide a kind of snake bone of endoscope, the snake bone has larger angle of bend, and can
Lighting fiber, image transmission optical fibre and pincers deferent are distributed well, avoid mutual extruding.
The technical solution adopted for the present invention to solve the technical problems is：
Pitch circle, each snake bone after pitch circle, some snake joints and snake bone before a kind of snake bone of endoscope, including the snake bone riveted successively
The both sides of the edge of section are the arc of indent, make to form angle between two neighboring snake joint edge.
Further, the line of centres of the line of centres and two engaging lugs of two arc wire-blocking boards is in each snake joint
80~90 ° of angles.
Further, the snake joint is divided into the preceding snake bone segment positioned at pitch circle side before snake bone and the pitch circle after snake bone
The rear snake bone segment of side, the width of snake joint is less than the width of snake joint in rear snake bone segment in preceding snake bone segment.
Further, the preceding snake bone segment includes 14 section snake joints, and the rear snake bone segment includes nine section snake joints.
The beneficial effects of the invention are as follows：
First, make between two neighboring snake joint edge in forming angle, by increasing capacitance it is possible to increase the flexibility between two neighboring snake joint,
So as to increase the angle of bend of whole snake bone；
2nd, snake bone segment is bent after preceding snake bone segment bending drives, and the width of snake joint is less than rear snake joint in preceding snake bone segment
The width of snake joint, the bending flexibility ratio of snake bone segment before raising in section；
3rd, in each snake joint the line of centres of two arc wire-blocking boards and the line of centres of two engaging lugs in 80~90 ° of folders
Angle, it is easy to carry out reasonable layout to lighting fiber, image transmission optical fibre and pincers deferent, reduces optical fiber and clamp the extruding between deferent, prolong
The service life of long optical fibers and pincers deferent.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is close-up schematic view of the present invention；
Fig. 3 is the stereogram of snake joint of the present invention；
Fig. 4 is snake joint, lighting fiber, image transmission optical fibre and the distribution side view enlarged drawing for clamping deferent of the present invention；
Fig. 5 is the bending schematic diagram of the present invention.
Embodiment
As shown in Figures 1 to 3, the present invention provides a kind of snake bone of endoscope, including before passing sequentially through the snake bone of the riveting of rivet 5
Pitch circle 1, some snake joints 2 and pitch circle 3 after snake bone, the both sides of the edge 7 of each snake joint are the arc of indent, make two neighboring snake
Angle theta be present between edge in joint；With reference to shown in Fig. 4, two arc wire-blocking boards 8 of snake joint are used to wear steel wire 4 respectively, often
The line of centres of two arc wire-blocking boards 8 and the line of centres of two engaging lugs 6 are in 80~90 ° of angles in individual snake joint；It is easy to
Reasonable layout is carried out to the first lighting fiber 9, the second lighting fiber 10, image transmission optical fibre 11 and pincers deferent 12, reduces optical fiber and pincers
The service life of extruding between deferent, extended fiber and pincers deferent.
With reference to shown in Fig. 5, as preferable, the snake joint be divided into the preceding snake bone segment 21 of the pitch circle side before snake bone with
And after snake bone pitch circle side rear snake bone segment 22, the width a of snake joint is less than snake in rear snake bone segment in preceding snake bone segment
The width b of joint；The preceding snake bone segment 21 includes 14 section snake joints, and the rear snake bone segment 22 includes nine section snake joints.
Make between two neighboring snake joint edge in forming angle theta, by increasing capacitance it is possible to increase the bending between two neighboring snake joint
Degree, so as to increase the angle of bend Φ of whole snake bone.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention；Appoint
What those skilled in the art, without departing from the scope of the technical proposal of the invention, all using the side of the disclosure above
Method and technology contents make many possible changes and modifications to technical solution of the present invention, or are revised as the equivalent reality of equivalent variations
Apply example.Therefore, every content without departing from technical solution of the present invention, the technical spirit according to the present invention are done to above example
Any simple modification, equivalent substitution, equivalence changes and modification, still fall within the range of technical solution of the present invention protects.
