In a preferred embodiment of the present invention, the opening direction of c-type occlusion portion 101 and the axial direction institute of controllable bending curved tube 10
At the first angle r may range from 10 ° -90 °, optimal engaging limit effect can be obtained positioned at the range, can either be taken
The convenience of Joining Technology is obtained, and firm limit effect can be obtained, therefore can be applied well in practice.
According to one embodiment of present invention, the C-shaped gap 102 that c-type articulation port 101 is inserted into should be likewise supplied with one and open
Mouthful, the direction of opening can be axial consistent with controllable bending curved tube 100, so that c-type occlusion portion 101 is conveniently embedded adjacent tube coupling
Tube coupling wall on C-shaped gap, facilitate two tube couplings to connect, increase the convenience of installation.
Multiple c-type occlusion portions can be provided projectingly on one end of each tube coupling 10 in the embodiment of the present invention is circumferential, with full
The bending direction requirement of sufficient different application scene.In another preferred embodiment of the invention, as in Fig. 3 to Fig. 5, Mei Geguan
One end circumferential direction of section 10 is equipped with two opposite c-type occlusion portions 101, accordingly opposite in the circumferential direction of its tube coupling wall to be equipped with two groups
The C-shaped gap 102 and ball bumps 103 matched with c-type occlusion portion 101, the adjacent ' of any two tube coupling 10 and 10 after engaging
Between have crack 104, crack 104 be spaced c-type occlusion portion setting and along the circumferentially extending of tube coupling, the controllable bending of the embodiment
Curved tube can be bent to both direction under control of the control means, and crack 104 provides curved for the bending of controllable bending curved tube 100
Bent space, when controllable bending curved tube bends deformation to a direction, the c-type occlusion portion 101 of each tube coupling 10 is in adjacent tubes
It saves and is subjected to displacement in the C-shaped gap 102 of 10 ', the rotation of certain angle specially occurs around ball bumps 103, while c-type lacks
The opening direction of mouth 102 also correspondingly rotates, and is spaced the opposite two sides crack 104 of the setting of c-type occlusion portion 101, then
Side gap increases, and the gap of the opposite other side reduces, to meet space needed for tube body is bent, when controllable bending curved tube is to the other side
Above-mentioned all changes reversely generate when bending, and the controllable bending curved tube 100 in the embodiment is bent to both direction.This
Field is it will be appreciated by the skilled person that the design of c-type occlusion portion should be not limited only to position sum number provided in the embodiment
Amount, can accordingly be designed according to specific application scenarios, to meet different bending direction demands.
From in Fig. 4 as it can be seen that each tube coupling 10 and adjacent 10 ' of tube coupling are formed by between crack 104 and are also provided with one
A or multiple slots 105, slot 105 is in the circumferentially extending of tube coupling 10, and slot 105 can be the various shapes such as round, rectangular or strip
Shape.The slot 105 for two strips being parallel to each other, 105 energy of slot are equipped between the crack 104 of each tube coupling 10 shown in Fig. 4
Space needed for tube body is bent enough is further provided for, increases the curved angular range of controllable bending curved tube, enhances the flexibility of tube body, and energy
Tube body weight and manufacturing cost are enough reduced, is very cleverly a kind of design in practice.
It is in one embodiment of the invention, also sharp in order to control user preferably to controlled deflection device
The tube coupling 10 being serially connected is controlled with control device.Further, control device is preferably one or more traction fiber,
It is bent for controlling the tube coupling 10 after connecting towards one or more directions, traction fiber is worn from the one end for the tube coupling 10 being serially connected
Enter, and be fixedly connected with the tube coupling 10 for being located at the other end outermost end of tube coupling 10 being serially connected, when external force is applied to traction
On silk, that is, when pulling traction fiber, the tube coupling being fixedly connected with traction fiber 10 can be driven to move, at this time the C on the tube coupling 10
It rotates between type occlusion portion 101 and the ball bumps 103 of 10 ' of tube coupling adjacent thereto, when the c-type occlusion portion of the tube coupling 10
101 go to after the extreme position of the C-shaped gap 102 of adjacent 10 ' of tube coupling and continue to pull traction fiber, can continue to drive adjacent tube coupling
10 ' continue to rotate, so that whole bending apparatus be made to bend；When bending apparatus is bent to angle needed for user
Afterwards, the external force being applied on bending apparatus and fixed traction silk are removed, bending apparatus can be made to be maintained at the bending position.
Further, in one embodiment of invention, tractive unit is preferably steel wire, and however, it is not limited to this, tractive unit
It can also be any filamentous structure, filamentary structure can also select any metal or non-metallic material.
In order to cooperate traction fiber preferably with bending apparatus, prevent traction fiber movable in the tube coupling 10 of bending apparatus,
Curved effect is influenced, can be also equipped in one embodiment of the invention, on tube coupling 10 one or more for fixed traction
The fixed part of silk.In one embodiment of the present of invention, one or two traction of setting preferably in multiple concatenated tube couplings 10
Silk is as control device 20 so that controlled deflection device can be bent towards one or two direction.Further, the embodiment
In, when tube coupling 10 is equipped with multiple fixed parts, multiple fixed parts are distributed on tube coupling 10, to guarantee that bending apparatus can be towards each
A direction bending.
Further, fixed part can be the round tube being fixedly connected on 10 inner wall of tube coupling, be also possible to be opened in pipe
Save the wire casing on 10 inner walls.Traction fiber is fixed by fixed part, can prevent traction fiber slippage from leading to controlled deflection device
Failure.Controlled deflection device according to the present invention can carry out tube coupling group using control unit curved according to the needs of users
Song, and can be bent towards any direction required for user, flexibly and easily.It is provided above that controllable bending curved tube is carried out
The preferred control mode of control, skilled person will appreciate that, it further include many control controllable bending curved tubes in practice to institute demander
To curved control mode or control device, and it is not limited only to control device provided in above preferred embodiment.
In conclusion controllable bending curved tube structure according to the present invention, stings due to constituting the c-type in each joint of swan-neck
Towards axially having angle with swan-neck, the ball bumps that when bending fastens are difficult from wherein falling off for the opening in conjunction portion, so that
Connection between each tube coupling more fastens, and c-type occlusion portion can be relatively moved to form displacement in C-shaped gap, thus
The curved space required for tube body is bent is provided, controls bending degree conducive to by command displacement degree, is surgical procedure
Providing great convenience property has very high practical value.
