Abstract
The invention discloses a kind of snake bone for endoscope head end bending section, described snake bone is the overall structure without rivet interlacement that continuous joint is constituted, and the joint of the snake bone designs for pitches.The snake bone for endoscope head end bending section of the present invention has advantages below：Meet below 2 millimeters of diameter and front end can bend superfine endoscope cephalic par requirement；The millimeter of bending radius 11.5 of whole snake bone；Between achievable two direction 90-degree bent -180 °.
Description
Technical field
The present invention relates to a kind of endoscope head end curved part structure, and in particular to a kind of for endoscope head end bending section
Snake bone.
Background technology
People have increasing need for the endoscope of smaller diameter and bending radius in the diagnosis and treatment process of modern medicine.Therefore put
Can just turn into the snake bone component of endoscope foremost meet the technological difficulties of requirement.And existing have rivet snake bone or without riveting
Nail can not meet requirement simultaneously with pitch snake bone in diameter and bending radius.Equally detect small-bore in industrial circle and have small curved
Curved tube road (cavity) be also user in the urgent need to.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of snake bone for endoscope head end bending section, can be straight
Footpath is less than under 2mm meets the big demand of bending radius simultaneously.
In order to solve the above technical problems, the invention provides a kind of snake bone for endoscope head end bending section, it is described
Snake bone be the overall structure without rivet interlacement that continuous joint is constituted, the joint of the snake bone designs for pitches.
Preferably, the snake bone for endoscope head end bending section of the invention, described snake bone is strong using counter-bending fatigue
Degree good stainless steel or titanium alloy metal material.
Further, the snake bone for endoscope head end bending section of the invention, described snake bone joint pitch is from front end
Gradually increase toward rear end, i.e., hold bending radius gradually to increase backward from front end when snake bone needs bending.
Further, the snake bone for endoscope head end bending section of the invention, described snake bone external diameter is less than 2mm.
Further, it is provided with the snake bone for endoscope head end bending section of the invention, described snake bone joint
There is bending traction steel wire in 3-4 lacing holes, described snake bone.
Further, between the snake bone for endoscope head end bending section of the invention, described each joint of snake bone
Provided with bending preset clearance, prevent from causing snake fracture disconnected because bending is excessive.
Further, the snake bone for endoscope head end bending section of the invention, described snake bone can compound bending,
The angle of bend of the snake bone is 90 ° -180 °.
Preferably, the snake bone for endoscope head end bending section of the invention, described snake bone forward end is peeped equipped with interior
The data wire being connected with affiliated endoscope is equipped with inside mirror, described snake bone.
The entirety for endoscope head end bending section of the present invention has advantages below without rivet pitches snake bone：
(1) a kind of below 1.8 millimeters of external diameter Φ is provided without the overall snake bone of rivet.
(2) whole snake bone is made up of different pitches, is held backward from front end when snake bone needs bending and is gradually formed radius ladder
Degree increase.
(3) reasonable Arrangement bends the position of traction steel wire cord hole so that easily reliable during bending.
(4) length of control snake bone can realize 90 ° -180 ° of angle of bend in producing.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is overall structural representation without rivet pitches snake bone of the present invention for endoscope head end bending section；
Fig. 2 is the use state schematic diagram of the present invention.
Wherein reference is：A-C, snake bone joint pitch；X, gap.
Embodiment
