Description
Technical field
The present invention relates to endoscope structure, especially a kind of endoscope mirror body fixation with steel wire structure and endoscope.
Background technique
Be widely used in endoscopic system in the medical field, usually by light guide section, Universal automatic cable portion, operation portion, insert
Enter portion, bending section, cephalic par composition.Bending section be usually controlled respectively by 4 steel wires by two handwheels of operation portion,
Under, the movement in left and right 4 directions after endoscope mirror body is inserted into human intracavity requires which kind of failure no matter occurs, will guarantee
Endoscope can be with Safe withdrawing human intracavity, and can be completed as far as possible when time endoscopy.Pass through band when operation hand wheel rotating
Moving gear rotation, gear drive chain movement, chain-driving steel wire component movement, and it is dynamic that steel wire component controls bending section execution bending
Make.
Fixation with steel wire structure in steel wire component in the prior art, including steel wire, steel wire pass through sleeve by soldering for steel
Silk and sleeve weld are fixed, and sleeve is located on link block, and link block is connect with chain.However, existing endoscope is using one section
After time, due to abrasion, aging etc., the weld seam at fixation with steel wire end may be broken or even fall off, if soldering weld seam is disconnected
Mirror body insertion section is in inside of human body when splitting, and when bending section is in bending maximum angle or larger angle, exist not can control it is curved
The curved risk of pars convoluta will be unable to continue endoscopic visualisation, or even have the risk for being difficult to exit human intracavity.For this purpose,
It needs to improve.
Summary of the invention
The first object of the present invention aiming in the fixation with steel wire structure of existing endoscope body, when soldering welding seam breaking without
Method is bent or is difficult to the defect of human intracavity, provides a kind of endoscope mirror body fixation with steel wire structure, the fixed structure by
Between steel wire and link block be arranged steel wire hold tightly component, by double locking mechanism by fixation with steel wire on link block, with
Welding seam breaking or after falling off, utilizes steel wire to hold the fixation of steel wire and link block that component is formed tightly, additionally it is possible to bending deformation is executed,
And conveniently, at leisure endoscope body is exited from inside cavity.The second object of the present invention is to provide a kind of with aforementioned steel
The endoscope of silk fixed structure.
To realize that the first purpose, the present invention adopt the following technical scheme that.
A kind of endoscope mirror body fixation with steel wire structure, including link block and sleeve are equipped with steel wire, steel wire outer end in sleeve
Sleeve outer end is fixed on by soldering weld seam；The plug screw covered in steel wire periphery is also screwed on the link block, plug screw passes through cone
Hole, which is equipped with, covers the elastic fixing sleeve on the steel wire；The taper hole big end of the elastic fixing sleeve is towards the sleeve；The bullet
Property fixing sleeve freely abuts against sleeve inner end.
Using the present invention of preceding solution, steel wire outer end is fixed on sleeve by soldering, and is indirectly fixed on
On link block；Meanwhile it being screwed on link block and covering the plug screw in steel wire periphery, it is equipped with by its taper hole and covers the bullet on steel wire
Property fixing sleeve, with by turning plug screw, the radial component moved axially by the conical surface applies radial force to elastic fixing sleeve, makes bullet
Property fixing sleeve inner hole contraction steel wire is held tightly.To make steel wire and link block form dual fixed structure, so as in conduct
After the welding seam breaking of main fixed structure or the failure that falls off, can make using the clasping structure as auxiliary fixing structure steel wire with
Link block is kept fixed connection relationship；To constitute double insurance structure when being used for endoscopic system, can in welding seam breaking or
It falls off in the case where failure, bending needed for meeting steel wire component and exits the relevant operations such as mirror body from inside cavity.Its structure
Simply, function is reliable, and when being used for endoscope, can eliminate camera lens cannot change posture or be not easy to exit the risk of cavity.
Preferably, the C-shaped opening nested structure of the elastic fixing sleeve.To cover the elastic construction to be formed, In using c-shaped opening
When plug screw taper hole inner wall squeezes C-shaped set, inner hole reduces the holding to be formed to steel wire, and intensity can be used and hardness is relatively high
Material production, to prolong the service life.
It is further preferred that the elastic fixing sleeve is made of flexible resin material.Further utilize resin
Elasticity improves firm grip.
Still more preferably, the resin material includes polycarbonate and nylon.With abundant polycarbonate and nylon
With the characteristics such as steel wire coefficient of friction is big and wear-resisting, it is ensured that firm grip degree, and prolong the service life.
Preferably, elastic fixing sleeve bush structure in a ring, and it is improved by addition the elastic material of the aggregate of intensity
Material is made.So as to relatively weak using intensity, but elastic fixing sleeve is made with the bigger elastomeric material of steel wire coefficient of friction, really
Connectivity robustness is protected, and enhances intensity by way of adding aggregate, to improve service life.
It is further preferred that the aggregate is glass fibre；The elastic material is made for rubber or TPE.With utilization side
Just it obtains, and the material of advantage of lower cost manufactures elastic fixing sleeve, to reduce manufacturing cost.
Preferably, monitoring alarm is equipped between the sleeve and steel wire, the monitoring alarm is for detecting
Soldering cracking after being broken or falling off, issues alarm signal.To monitor the weldquality situation between steel wire and sleeve in real time,
After the quality problems for cracking occur, being broken or falling off and alarm is such as repaired or is peeped in limiting to adopt remedial measures
The access times etc. of mirror.Since service life is relatively short for soldering for elastic fixing sleeve, only relying on elasticity
In the case where the fixed steel wire of fixing sleeve, it usually needs limitation access times, to prevent to occur to be bent or be not easy to exit cavity
The phenomenon that occur.It, can also be fixed as emergency measure, before alarm, spiral shell by resilient sleeve in the scheme with warning device
Plug does not compress resilient sleeve, and steel wire is only fixed by weld seam.After there is alarm, resilient sleeve is compressed tightening plug screw, and by resilient sleeve
Steel wire is held tightly, to form relay working condition.
Preferably, the monitoring alarm passes through resistance value between real-time detection sleeve and steel wire, and in the resistance value
Triggering alarm when increasing to setting value.To judge whether scolding tin cracks or be broken by the monitoring of increased resistance value, in addition it is de-
It falls；Triggering alarm when the setting of its alarm threshold value can satisfy scolding tin cracking；Using alarm signal, scolding tin and elasticity holding can
Relay working condition is formed, to further increase reliability.
To realize the second purpose, of the invention is adopted the following technical scheme that.
A kind of endoscope, including mirror body are connected by link block, sleeve with steel wire between mirror body and chain；Steel wire and company
It connects between block using the fixation with steel wire structure for realizing first invention purpose.
Using the present invention of preceding solution, fixation with steel wire structure formation mirror body and the reliable of chain is made full use of to consolidate
Fixed, can effectively eliminate endoscope mirror body in surgical procedure cannot change posture by steel wire, and be not easy to move back from inside cavity
Hidden danger out.
The invention has the advantages that fixation with steel wire structure, structure is simple, function is reliable；With in the fixed structure
Sight glass cannot not change posture and be not easy the hidden danger exited.
