Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of detent mechanism that turns to that is used for endoscope.
Background technology
Present endoscope generally through scissor handle with turn to its bending of steel wire control to turn to, manipulation accuracy is not high, and is not accurate enough to the control of steering angle; Visible angle is less, the bad accurate location of steering angle, and the operation along with the medical worker in operation process is carried out; Turn to the angle of steel wire can be more or less deviation to some extent; Make that the degree of accuracy of operation is not high, simultaneously because the technical bottleneck that line size and ablepsia angle cause brings hidden danger for the safety of operation.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of angle-adjusting mechanism of endoscope-use to be provided, and it is simple to operate that it is had, the characteristics of convenient control steering angle.
The technical scheme of this utility model is achieved in that a kind of detent mechanism that turns to that is used for endoscope; Its special character is: it comprises handle head, taper knob, eccentric, driving lever, rotating shaft, in handle head, is provided with the locating hole that is used to place rotating shaft, and rotating shaft one end connects eccentric; The other end connects driving lever; Rotating shaft is axial arranged along handle head, and the handle head surface along the circumferential direction is provided with an open slot, driving lever be positioned at open slot; The lower end of driving lever is fixedly connected with rotating shaft, eccentric and rotating shaft arranged off-centre.
As preferred version, the end sides that turns to the detent mechanism open slot of described endoscope is provided with stopper slot, and when driving lever was positioned at this stopper slot, eccentric was pressed on the inner surface of taper knob, is in locking state.
Further, the detent mechanism eccentric surface that turns to of described endoscope is circular arc.
The utlity model has that spacing reliable, simple in structure, process and assemble is convenient, the independence of spacing adjusting is strong and the characteristics of adjusting, convenient fixing.
Description of drawings
Fig. 1 is the structural representation of this utility model
Fig. 2 is open slot and the sketch map of stopper slot in this utility model
Among the figure: 1. handle head, 2. taper knob, 3. eccentric, 4. driving lever, 5. rotating shaft, 6. locating hole, 7. open slot, 8. stopper slot.
The specific embodiment
Below in conjunction with the performance of accompanying drawing detailed description this utility model, but they do not constitute the restriction to this utility model, only do for example.
Present embodiment provides a kind of detent mechanism that turns to that is used for endoscope, mainly comprises handle head 1, taper knob 2, eccentric 3, driving lever 4, rotating shaft 5, in handle head 1, is provided with the locating hole 6 that is used to place rotating shaft 5; Rotating shaft 5 one ends connect eccentric 3, and the other end connects driving lever 4, and rotating shaft 5 is axial arranged along handle head 1; Handle head 1 surface along the circumferential direction is provided with an open slot 7; Driving lever 4 be positioned at open slot 7, the lower end of driving lever 4 is fixedly connected with rotating shaft 5, eccentric 3 and rotating shaft 5 arranged off-centre.The end sides of open slot 7 is provided with stopper slot 8, and when driving lever 4 was positioned at this stopper slot 8, eccentric 3 was pressed on the inner surface of taper knob 2, is in locking state.Eccentric 3 surfaces are circular arc.The lower end of driving lever 4 is fixedly connected with rotating shaft 5 in handle head 1, and the upper end of driving lever 4 is placed in the open slot 7 on the handle head 1.
During this utility model work; The upper end that operator control driving lever 4 horizontally slips in open slot 7, drives eccentric 3 through rotating shaft 5 when driving lever 4 slides and rotate in open slot 7, makes eccentric 3 rotate through stirring driving lever 4 to one ends; The rubbing surface of eccentric 3 turns to the top from the below; Contact with the handle head 1 internal friction face of endoscope, increase the frictional force between an eccentric 3 and endoscope handle 1 inner face, realize turning to the location.In endoscope's actual mechanical process, the doctor is through detecting after the focus, in the time of doing further treatment according to the focus that detects; Need endoscope focus is located exactly and to aim at, at this moment only need stir the driving lever 4 of this utility model, make driving lever 4 in the open slot 7 of endoscope handle 1 outer surface, slide; Drive rotating shaft 5 along circumferentially rotating; And then drive eccentric 3 and circumferentially rotate, make that the rubbing surface of eccentric 3 forwards to from the below above, rubbing surface contacts with endoscope handle 1 inner surface; Increase the frictional force between eccentric 3 and the endoscope handle 1, reached the effect of positioning and fixing.Turn to detent mechanism in this utility model, the use that matches of handle head 1 and taper knob 2 is in operative process; The soft sheath of endoscope detects in patient's body, accomplishes spinning movement location afterwards, fixed handle cover 2; Stir driving lever 4, drive eccentric 3 rotations be positioned at endoscope handle 1, the rubbing surface of eccentric 3 contacts with handle head 1 inner surface; Increased frictional force between the two, made between handle head 1 and the taper knob 2 spacing fixing.
The content of not doing in this description to describe in detail belongs to this area professional and technical personnel's known prior art.
