Description
Technical field
It is that a kind of can be grasped with the Sigmoidoscope of one-handed performance specifically the present invention relates to a kind of operation handle of Sigmoidoscope
Make handle, belong to Sigmoidoscope operation handle technical field.
Background technology
With the development of video image dendoscope and imaging technique, Sigmoidoscope two-man method starts to replace double method to turn into master
Stream.Sigmoidoscope two-man method only needs to colonoscopy doctor, and one can just singly complete.User's energy during one man operation
Situations such as Sigmoidoscope tip is retreated, the resistance of rotation changes preferably is perceived, so that more conducively doctor is observed and carried out respectively
Plant fine treatment operation.Although although existing operation handle has been able to allow doctor is single to carry out colonoscopy
Look into, but there are still many inconvenience and problem.
At present, the problem of Sigmoidoscope operation handle of one-handed performance is present mainly has：1) rotational lock knob is as above descended, with
And left and right locking knob does not also need in the range of the manipulation of human hand, sometimes operate by the right hand；2) Sigmoidoscope bending section
When bending, due in angular adjustment state, not locked to angle deflection mechanism, therefore intervention hose surface is coated on
Metal net cover and rubber layer can produce certain elastic deformation, after the operating physical force of human hand is removed, the elastic deformation existed
Bending section will be caused to automatically return to centre position, therefore when continuously adjusting knob, doctor must use another finger to assist
Thumb is operated, so as to prevent knob from turning round；3) due to that can not control two angle adjusting buttons simultaneously, doctor is difficult to
By Sigmoidoscope tip part regulation to a preferable deflection angle.
Details are as follows for the shortcoming that prior art is present：
(1) it is not easy to the operation of operator.For the deflection of Sigmoidoscope tip, prior art is simply by the deflection of tip point
Solve the deflection (angular deflection, left and right angular deflection above and below i.e.) for two different directions.Therefore operator adjusts the deflection of tip
It during angle, can only adjust after an angular deflection, then the angular deflection of other direction has been adjusted, be not easy to operator's
Operation.In addition, after an angular deflection has been adjusted, it is necessary to carry out manual locking to this angle, then adjust the opposing party
Locked to angular deflection and angle.If obtained angle is not up to expection, in addition it is also necessary to which manual unlocking is adjusted again.It will so drop significantly
The operating efficiency of low operator.
(2) without overload protection.Because the driving mechanism of existing colonoscopic techniques is substantially gear drive, work as operator
Operating physical force is excessive or during excessive operation amplitude, Sigmoidoscope tip deflection angle can be caused drastically to change, easily caused to patient's intestines
The damage in road, or even bowel perforation.Accordingly, it would be desirable to be redesigned to the driving mechanism of Sigmoidoscope, using the teaching of the invention it is possible to provide overload protection.
(3) without a kind of guarantee 3DOF and the tight transmission mechanism of ball chuck of torque can be transmitted.This clamp system can
Ensure ball X, Y, the rotation of Z axis and the transmission of moment of torsion, at the same must limiting ball along X, Y, the movement of Z-direction；
