Description
【Technical field】
The invention belongs to technical field of medical instruments, and in particular to a kind of comprehensive transfer of endoscope-use.
【Background technology】
The steering mechanism that current endoscope is used is generally the technology with snake bone as Typical Representative.Operation parts are rotation
Button.Such as：Gastrointestinal Endoscopes have two knobs, and big knob is responsible for controlling lower angle, small knob to be responsible for controlling left and right angle, size knob
There is a lock, when certain angle is adjusted on inverse time needle plate during this lock, just can be angle lock on the position, convenient doctor
The diagnoses and treatment at the Shi Jinhang positions.
It is the standing procedure of current endoscope industry centered on snake bone technology.It has as a drawback that：1st, due to using
Be snake bone, maximum reason is the volume that its mechanism needs in itself, so directly results in the limited of endoscope appearance and size, according to
Current technique is difficult for scope to accomplish below diameter 3mm.2nd, due to using snake bone, most scabrous pin problem, bag
Traction and lead of the lead in main flexible tube integrity problem in itself are included, is all that industry cannot technically overcome.3rd, also
It is exactly snake bone mechanism cost in itself to have, and due to its technique and material, causes of a relatively high cost, unlikely to be applied
Disposable endoscope on.4th, the part of traction steel wire：Chain, bone wheel steel wire, line wheel.Bone wheel steel wire and line wheel are easily broken,
Particularly Sigmoidoscope, so the maintenance of the part is very common.5th, Wire mount is welded in the end of steel wire, the portion with traction steel wire
Part such as chain, line wheel etc. are connected to, and play a part of to pull steel wire.Such as mirror leak or not prison welding, Wire mount just holds
Easy sealing-off causes non-angular, and this is a kind of most common failure.
【The content of the invention】
The technical problems to be solved by the invention are to provide a kind of comprehensive transfer of reliable and stable endoscope-use.
What the present invention was realized in：
A kind of comprehensive transfer of endoscope-use, including a main flexible tube, the main flexible tube is solid plastic flexible pipe；It is described
The top of main flexible tube is arranged a lens barrel, for fixed endoscope camera lens；The tail end of the main flexible tube connects an operation handle；
Three passages, respectively first passage, second channel, third channel are offered in the main flexible tube；
Steering mechanism is embedded in the first passage；The main element of the steering mechanism is steel wire rope；The steel wire rope
Top fasten sleeve, for fixed lens barrel；The steel wire rope has one section to be arranged one near the position of the operation handle
Spring；Steel wire rope periphery between the spring and the operation handle fastens a hollow steel pipe, for fixing the operation
Handle；
Lighting fiber is embedded in the second channel；
The third channel is hollow, used as the entrance passage of medicine equipment.
Further, the steering mechanism also includes a nylon hollow pipe, and the nylon hollow pipe is enclosed within the steel wire rope,
Play a part of to protect steel wire rope；The scope of the nylon hollow pipe cladding is from described sleeve pipe to the steel wire between the spring
Ran.
The advantage of the invention is that：Stable operation reliability of the present invention.According to actual needs, doctor is carrying out handle operation
When, the length and speed for shrinking and decontroling steel wire rope are controllable, so control the flexibility of main flexible tube, the achievable 180 degree of maximum
Bending, and can as needed, in 360 degree of a certain angles of either direction lockable.
【Brief description of the drawings】
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is top view of the invention.
Fig. 2 is A-A sectional views of the invention.
Fig. 3 is use state schematic diagram of the invention.
【Specific embodiment】
As depicted in figs. 1 and 2, the comprehensive transfer of a kind of endoscope-use, including a main flexible tube 100, the main flexible tube 100
It is solid plastic flexible pipe, main flexible tube 100 is the main part of transfer work, is the core for fixing each part.
The top of main flexible tube 100 is arranged a lens barrel 200, for fixed endoscope camera lens 300；The tail of the main flexible tube 100
One operation handle (not shown) of end connection.
Three passages, respectively first passage 101, second channel 102, third channel 103 are offered in main flexible tube 100.
Steering mechanism is embedded in first passage 101；The main element of steering mechanism is steel wire rope 1011；The steel wire rope
1011 top fastens sleeve 1012, for fixed lens barrel 200；Sleeve pipe 1012 is socketed and by extruding with steel wire rope 1011
Formula connected mode is fixed, and increases the contact area of steel wire rope 1011, steel wire rope 1011 is more preferably fixed with main flexible tube 100.
Lens barrel 200 plays fixed endoscope camera lens 300, is fixed with glue with main flexible tube 100.Steel wire rope 1011 is close to
The position of operation handle has one section to be arranged a spring 1013；The periphery of steel wire rope 1011 fastening between spring 1013 and operation handle
A fixed hollow steel pipe 1014, for fixing operation handle.Nylon hollow pipe 1015 is enclosed within steel wire rope 1011, plays protection steel wire
The effect of rope 1011；The scope of the cladding of nylon hollow pipe 1015 is from sleeve pipe 1012 to the steel wire rope 1011 between spring 1013
Section.Hollow steel pipe 1014 is to play fixed steel wire rope 1011, and is fixedly connected with operation handle, facilitates drawing.
Lighting fiber is embedded in second channel 102.
Third channel 103 is hollow, used as the entrance passage of medicine equipment.
When operator is by pulling steel wire rope 1011, endoscope lens 300 it is overall can 180 degree bending, when needing adjustment
During the bending direction of lens barrel 200, main flexible tube 100 is rotated in circumference arbitrarily angled, and can be real angle lock on the position
Existing 360 degrees omnidirection bending, facilitates doctor to carry out the diagnoses and treatment at the position.
Operation principle：When doctor is packed up by operation handle pull-up steel wire rope 1011, so that the length of steel wire rope 1011
Degree is short compared with the length of main flexible tube 100, so force main flexible tube 100 to produce shrinkage to bend, and the part for bending, can be from rigidity most
Occur at weak spring 1013.So endoscope produces this action to facilitate the doctor to carry out the diagnoses and treatment at the position.When doctor is logical
When crossing handle relieving steel wire rope 1011, the meeting resilience of spring 1013 causes main flexible tube 100 to reset.
According to actual needs, doctor shrinks and the length and speed of relieving steel wire rope 1011 can when handle operation is carried out
Control, so controls the flexibility of main flexible tube 100, maximum to be capable of achieving the bending of 180 degree, and can be any at 360 degree with according to needs
The a certain angle of direction lockable.As shown in Figure 3.
Stable operation reliability of the present invention.According to actual needs, doctor shrinks and decontrols steel wire rope when handle operation is carried out
Length and speed it is controllable, so control the flexibility of main flexible tube, the bending of the achievable 180 degree of maximum, and can as needed,
In 360 degree of a certain angles of either direction lockable.
Preferable implementation use-case of the invention is the foregoing is only, is not intended to limit the scope of the present invention.It is all
Within the spirit and principles in the present invention, any modification, equivalent and improvement for being made etc., should be included in of the invention
Within protection domain.
