Abstract
The invention provides an endoscope. The endoscope comprises a drive mechanism, an insertion tube, pull wires and a probe, wherein the probe is arranged on the far end of the insertion tube, the pull wires are connected with the drive mechanism and the probe, and the drive mechanism is used for driving the pull wires to move so as to drive the insertion tube to be bent, therefore, the position of the probe is changed. The endoscope comprises a main machine and tension sensors, wherein the main machine is electrically connected with the drive mechanism and the tension sensors, the tension sensors are used for inducing the external force suffered by the pull wires and transmitting induction signals to the main machine, and the main machine controls the drive mechanism according to the induction signals. The arranged tension sensors are used for inducing the external force suffered by the pull wires, so that the real-time stressing condition on the pull wires can be detected, therefore, the situation that when the obstruction suffered by the probe exceeds the ultimate tension of the pull wires, the drive mechanism still pulls the pull wires is avoided, thus the breakage of the pull wires due to overstressing is prevented, and further, the scrap of the endoscope caused as the pull wires are pulled to be broken off is also avoided.

Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present invention understand usually.The object of term used in the description of the invention herein just in order to describe specific embodiment, is not intended to be restriction the present invention.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Alleged far-end, refers to the one end away from operator herein, and near-end refers to the one end near operator.
Please refer to Fig. 1, the endoscope that one embodiment of the invention provides comprises driving mechanism 10, intubate 11, draught line 12, probe 13, main frame 14, pulling force sensor 15.
Described driving mechanism 10 drives draught line 12 for drawing, thus makes the flexural deformation of intubate 11 energy, and then probe 13 is drawn arrival precalculated position.Described driving mechanism 10 comprises power, such as, be servomotor etc., and drive mechanism, such as, be chain drive, gear drive etc.This drive mechanism is connected with draught line 12, and drive mechanism transmits the kinetic energy of power, and draught line 12 is moved.
Draught line 12 far-end is connected with probe 13, and draught line 12 near-end is connected with driving mechanism 10.When being subject to the pulling force of driving mechanism 10, draught line 12 traction makes intubate 11 flexural deformation, makes probe 13 change position simultaneously.In one embodiment, draught line 12 can be integrated and be arranged in intubate 11, and namely draught line 12 is located in intubate 11.
In one embodiment, draught line 12 can be set to many, to be connected with the diverse location of probe 13, and then during draught line 12 under tension of diverse location, probe 13 can be made bending towards relevant position, to arriving precalculated position.Accordingly, driving mechanism 10 also can arrange multiple, to drive corresponding draught line 12.In embodiment shown in figure, driving mechanism 10 is two, draught line 12 is four, a driving mechanism 10 corresponding two draught lines 12 simultaneously, these two draught lines 12 are connected to relative 2 points of probe 13, and when driving mechanism 10 pull wherein a draught line 12 time, an other draught line 12 is relaxed state accordingly, makes probe 13 can change position neatly.
The near-end of intubate 11 to be connected with driving mechanism 10 by components such as a similar housing or support bodys and to arrange, and the far-end of intubate 11 connects and arranges described probe 13.Intubate 11 at least can flexural deformation near a part for far-end, thus when being subject to the pulling force of draught line 12, flexible distortion, thus the position changing probe 13.
Described probe 13 is arranged on the far-end of intubate 11, arranges the components and parts such as camera lens in probe 13, realizes the function of far-end detection.
Described pulling force sensor 15 is for responding to external force suffered by draught line 12.In one embodiment, pulling force sensor 15 can be arranged on the near-end of draught line 12, or is connected with the drive mechanism in driving mechanism 10, with can sense draught line 12 stressed be changed to prerequisite.
In one embodiment, each draught line 12 correspondence arranges a pulling force sensor 15, to responding to the stressing conditions of each draught line 12 respectively.
Described main frame 14 is electrically connected with driving mechanism 10, pulling force sensor 15.In embodiment shown in the figure, main frame 14 sends holding wire 102 by order and is connected with driving mechanism 10, by the operation on main frame 14, and can the operation of direct controlling and driving mechanism 10.Main frame 14 is connected with pulling force sensor 15 by tension feedback holding wire 103, and the induced signal of described pulling force sensor 15 can feed back to main frame 14.Main frame 14 can be the device with calculation function comprising processor, and comprises the device with memory function of memorizer, etc.It is such as microcomputer etc.
Wherein in an embodiment, described main frame 14 arranges display screen 141, the induced signal that described pulling force sensor 15 feeds back to main frame 14 can be presented on this display screen 141 with optical signal, thus operator can be allowed to know the stressing conditions of draught line 12 more intuitively.This optical signal can be in digital form, or represents the form of different pulling force grade with different colours, etc., intuitively embody the stressing conditions of draught line 12.
Wherein in an embodiment, described main frame 14 arranges alarm lamp 142, when suffered by draught line 12, external force exceedes set value, described alarm lamp 142 is opened.Such as, can by arranging a stressed early warning value of draught line on main frame 14, when external force suffered by draught line 12 reaches or exceedes this early warning value, alarm lamp 142 reminds operator with flicker or long bright mode.This early warning value can lower than the pulling force ultimate value of draught line 12.Be appreciated that the pulling force ultimate value of draught line 12 is, when draught line 12 is by when being more than or equal to the pulling force of this value, draught line 12 will be pulled off.
Wherein in an embodiment, described main frame 14 arranges rocking bar 143, described rocking bar 143 is for operating driving mechanism 10.This rocking bar 143 by the processor in electrical connection main frame 14, and can be electrically connected driving mechanism 10 further, makes operation rocking bar 143 can operate driving mechanism 10.Further, can arrange rocking bar 143 wave direction with probe 13 bending direction consistent, thus can operate this probe 13 more intuitively.
When operating this endoscope, driving mechanism 10 drives draught line 12 to move, and then drives probe 13 to bend.When probe 13 runs into the barrier 101 of side, if the resistance of barrier 101 is comparatively large, then probe 13 can not continue to move towards this direction.Now, because arranging pulling force sensor 15, immediately can know pulling force situation suffered by draught line 12, operator thus can be reminded to stop the operation of driving mechanism 10, prevent this driving mechanism 10 too to pull draught line 12, avoid draught line 12 to be pulled off.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
