A kind of endoscope including above-mentioned endoscope snake bone.
By adopting the above scheme, the utility model has the beneficial effects that：The utility model endoscope snake bone is using stainless
Steel pipe is cut, easy to process, and manufacturing cost is relatively low；And since the spacing of its special curved slot is arranged, the snake cyrtosis
Form is preferable, and bending flexibility is higher.The utility model endoscope equally has the advantages that above.
Description of the drawings
Fig. 1 is the structural schematic diagram of metal snake-bone in the utility model embodiment；
Fig. 2 is the vertical view of metal snake-bone in Fig. 1；
Fig. 3 is the left view of metal snake-bone in Fig. 1.
Specific implementation mode
The utility model is further described below in conjunction with the embodiment shown in that figure.
The utility model proposes a kind of endoscope snake bone, the structure that Fig. 1 show endoscope snake bone in the present embodiment is shown
It is intended to, Fig. 2 is its vertical view, and Fig. 3 is its left view.The endoscope snake bone includes bending tube body 1, is located at bending tube body 1
On curved slot 2；It is provided with steel wire rope in the pipe of bending tube body 1 and crosses slot 3, steel wire rope crosses bending of the slot 3 by position
The wall portion of tube body 1 is inwardly recessed, and is passed through, is arrived with allowing steel wire rope to be crossed in slot 3 from the steel wire rope since snake bone rear end
Up to snake bone front end, which, which crosses slot 3, to effectively prevent steel wire rope to shake.In addition, (more being connect in 1 front end of bending tube body
One end of nearly user) on neighbouring side wall, it is provided with steel wire rope bending location hole 4, stretched out in slot 3 will be crossed from steel wire rope
When the head of steel wire rope is weldingly fixed on the side wall of bending tube body 1, the weldering on the head and bending tube body 1 of steel wire rope is determined
Connect position.5 be dowel, the part not cut off between each joint in cutting for bending tube body 1.In the present embodiment,
Steel wire rope is crossed slot and is made of Sheet Metal Forming Technology.
The bending tube body is integrated pipe, and as whole is managed, rather than be spliced.
Along the direction from the front end of endoscope snake bone to rear end, the spacing of curved slot 2 successively increases, or in batches successively
Increase.It is so-called to successively increase in batches, i.e., from front end to rear end, the spacing of curved slot is divided into batch, the 1st spacing is to the n-th 1
Spacing is first spacing, and the n-th 1 spacing to the n-th 2 spacing are second batch spacing ... ..., n-th (m-1) to n-th m spacing
It is equal with a batch spacing for kth batch spacing, and from front end to rear end, each batch of spacing is sequentially increased, i.e. first spacing ＜ second
Criticize spacing ＜ ... ＜ kth batch spacing；Wherein, n1, n2, n (m-1), nm, k are the positive integer being sequentially increased.So-called front end, refers to
It is endoscope snake bone when in use close to one end of patient；So-called rear end refers to that endoscope snake bone leans near operation when in use
One end of person such as doctor.In the spacing of curved slot, maximum spacing is bigger by 10%~40% than minimum spacing.
The cross section of curved slot be triangle, with ensure realize snake cyrtosis under the premise of, compared with documents,
The material for less removing snake bone itself, improves the reliability of snake bone.
Each curved slot 2 is located in the same cross section of bend body 1.
The angle L of curved slot 2 is arranged so that the flexible angle of snake bone.Specifically, in the angle of setting curved slot 2
When, the sum of the angle of unilateral each curved slot enables snake bone bend in one direction.
In the present embodiment, the material of endoscope snake bone is metal, which is stainless steel.
The utility model also proposed a kind of endoscope including above-mentioned endoscope snake bone.
The utility model endoscope snake bone is cut using stainless steel tube, easy to process, and manufacturing cost is relatively low；And due to
The spacing of its special curved slot is arranged, and the snake cyrtosis form is preferable, and bending flexibility is higher.The utility model endoscope is same
Sample has the advantages that above.
This reality can be understood and applied the above description of the embodiments is intended to facilitate those skilled in the art
