Description
Technical field
The present invention relates to a kind of operating grip of colonoscope, specifically, be a kind of can the colonoscope operating grip of one-handed performance, belong to colonoscope operating grip technical field.
Background technology
Along with the development of video image dendoscope and imaging technique, colonoscope two-man method starts to replace double method and becomes main flow.Colonoscope two-man method only needs that colonoscopy doctor is single just can independently complete.During one man operation, user can the perception colonoscope tip situation such as change in resistance of retreating, rotating better, thus is more conducive to doctor and carries out observing and carry out various meticulous treatment operation.Although although existing operating grip can make doctor singlely can carry out colonoscopy, still there is much inconvenience and problem.
At present, the colonoscope operating grip Problems existing of one-handed performance mainly contains: 1) as above descend rotational lock knob, and left and right locking knob is not within the scope of the manipulation of staff, sometimes also needs to operate by the right hand; 2) when colonoscope bending section bends, owing to being in angular adjustment state, angle deflection mechanism is not locked, therefore the metal net cover and the rubber layer that are coated on intervention hose surface can produce certain elastic deformation, after the operating physical force removing staff, the elastic deformation of existence will make bending section automatically return to centre position, therefore when continuous adjusting knob, doctor must use another finger to assist thumb to operate, thus prevents knob from turning round; 3) owing to cannot control two angle adjusting button simultaneously, doctor is difficult to first for colonoscope end portion to be adjusted to a desirable deflection angle.
Details are as follows for the shortcoming that prior art exists:
(1) operation of operator is not easy to.For the deflection of colonoscope tip, the deflection of tip is just decomposed into the deflection (i.e. upper and lower angular deflection, left and right angular deflection) of two different directions by prior art.Therefore, when operator regulates the deflection angle of tip, after an angular deflection can only have been regulated, then the angular deflection of other direction is regulated, be not easy to the operation of operator.In addition, after an angular deflection has regulated, manual locking must have been carried out to this angle, then regulate other direction angular deflection and angle locking.If the angle obtained does not reach expection, manual unlocking is also needed to regulate again.To greatly reduce the work efficiency of operator like this.
(2) overload protection is not had.Driving mechanism due to existing colonoscopic techniques is substantially all gear drive, when operator's operating physical force is excessive or operation amplitude is excessive, colonoscope tip deflection angle can be made sharply to change, easily cause the damage to Intestinal Mucosal Injury in Patients Undergoing, even bowel perforation.Therefore, need to redesign the driving mechanism of colonoscope, can overload protection be provided.
(3) do not have a kind ofly to ensure 3DOF and can the tight drive mechanism of ball chuck of transmitting torque.This clamp system can ensure ball X, Y, the rotation of Z axis and the transmission of moment of torsion, must limit ball along X, Y, the movement of Z-direction simultaneously;
