Description

Rotating mechanism and electronic fiber soft mirror

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a rotating mechanism and an electronic fiber soft mirror.

Background

The electronic fiber soft mirror is widely used in the medical field. In general, such a soft lens insertion portion is provided with a bending portion on the distal end side, the bending portion being constituted by a plurality of bending segments, and the bending portion being bent in the up-down direction or the left-right direction by pulling an operation wire connected to the bending segments.

However, in the conventional art, the bending of the bending portion is generally designed to be bent in both the up-down direction and the left-right direction, and the disadvantage of this is that the head of the bending portion can be bent in only one plane in both directions, as shown in fig. 1 below, which results in that the doctor can only have the views in both bending directions when looking at or looking directly at the operation, and if the direction of the view is to be adjusted, it is necessary to rotate the entire handle in the axial direction. In actual operation, the manner in which the doctor holds the handle is shown in fig. 2, so that the doctor holds the handle to ensure that the bending control handle is twisted at any time to realize bending control, and controls other control buttons on the handle. In this way, if the entire handle is required to be axially rotated, the operator is required to swing the wrist in the case of small angle rotation, and the operator can only be realized by tilting or shifting the body in the case of large angle rotation. This tends to cause difficulty for the operator and also fatigue for the operator if the operator is physically twisted for a long period of time.

Example 1

Referring to fig. 3-7, this embodiment provides a rotation mechanism, including a handle shaft 100, a rotation cover 110 is sleeved on the outer side of the handle shaft 100, the rotation cover 110 is in rotation fit with the handle shaft 100, and a fitting groove 111 is provided in the rotation cover 110; the device further comprises an insertion part 101, wherein a fixing wedge block 120 is arranged at the end part of the insertion part 101, and the fixing wedge block 120 is matched with the matching groove 111.

The rotating mechanism of the present embodiment is used in a soft mirror device and is connected to the insertion portion 101, so that the insertion portion 101 can be driven to rotate while rotating around the handle.

The handle shaft 100 is arranged at the position of the conventional soft lens handle, the rotatable rotating cover body 110 is arranged at the outer side of the handle shaft 100, the end part of the insertion part 101 of the soft lens device is matched with the matching groove 111 through the fixing wedge block 120, the linkage action with the rotating cover body 110 is realized, and when the rotating cover body 110 rotates, the inner wall of the matching groove 111 can apply acting force to the fixing wedge block 120, so that the insertion part 101 rotates along with the rotation of the rotating cover body 110.

It is conceivable that in the conventional soft mirror device, the bending portion at the other end of the insertion portion 101 may be turned and bent only in the same plane, but the rotation mechanism of the present embodiment allows the bending portion to rotate along with the rotation of the insertion portion 101, which is equivalent to increasing the degree of freedom of movement of the bending portion, thereby improving the convenience of use.

It is conceivable that the fixing wedge 120 may be a structure that is common in the mechanical field such as keys, flat squares, etc. and can transmit torque, and the mating groove 111 is configured according to the specific shape of the fixing wedge 120. The fixing wedge 120 and the insertion portion 101 may be connected by adhesion or the like.

As an optional implementation manner of this embodiment, the handle shaft 100 is provided with a limiting groove 102, the rotary cover 110 is provided with a protruding member 103, the protruding member 103 is matched with the limiting groove 102, and the protruding member 103 is in sliding fit with the limiting groove 102. In this embodiment, the positioning groove 102 and the protruding member 103 prevent the rotary cover 110 from being separated from the handle shaft 100 during rotation, thereby achieving the positioning function of the rotary cover 110.

In further conceivable embodiments, the length of the limiting slot 102, or the radian thereof, may be limited to the rotational travel of the rotary cover 110, for example, when the central angle corresponding to the radian of the limiting slot 102 is ninety degrees, the rotational travel of the rotary cover 110 is within ninety degrees, and the radian of the limiting slot 102 may be adjusted according to the actual use situation. It is conceivable that, when the extending manner of the limiting groove 102 is a combination of ninety degrees of axial clockwise rotation and ninety degrees of counterclockwise rotation of the insertion portion 101, the central angle corresponding to the limiting groove 102 as a whole is one hundred eighty degrees, so that the rotation of the rotary cover 110 by ninety degrees in the clockwise and counterclockwise directions can be satisfied.

Since the structure such as the soft mirror inner circuit is not completely rotatable, and only a certain degree of rotation is possible by using the elasticity of the material and the assembly margin, the length of the limit groove 102 needs to be set according to the internal structure of the soft mirror device.

As an alternative implementation manner of this embodiment, a plurality of ring grooves are arranged on the rotary cover 110 in parallel, and O-rings 104 are arranged in the ring grooves, and the O-rings 104 are abutted against the handle shaft 100. In this embodiment, the O-ring 104 is assembled by rotating a plurality of ring grooves arranged in parallel on the cover 110, which plays a limiting role on the O-ring 104. The O-ring 104 is used as a connection structure between the rotary cover 110 and the handle shaft 100, and is used to provide a damping force for the rotary cover 110, when an operator rotates the rotary cover 110 to a desired angular position, the rotary cover 110 can be stopped at the desired position due to the damping force provided by the O-ring 104, and is not disturbed and is randomly rotated.

As an alternative implementation manner of this embodiment, the O-ring 104 is made of silica gel or rubber.

As an alternative implementation of this embodiment, the O-ring 104 is interference fit between the handle shaft 100 and the rotary cover 110. The O-shaped ring 104 assembled by interference is adopted, so that damping force can be better provided, and the interference is adjusted to meet the damping force of different requirements.

As an alternative implementation manner of this embodiment, the fixing wedge 120 includes opposite planar ends, and two sides of the planar end are provided with cambered surface ends. The present embodiment is a setting manner of the fixed wedge 120, the fixed wedge 120 forms an external structure by using a planar end and an arc end, the planar end is used for transmitting torque, and the arc end is used for more conveniently realizing the assembly between the fixed wedge 120 and the rotary housing.

As an optional implementation manner of this embodiment, the limiting groove 102 is an arc groove, a central angle of the arc groove is one hundred eighty degrees, and the central angle bisector coincides with the rotation center line of the insertion portion 101. In this embodiment, the limiting groove 102 is an arc groove, and the corresponding central angle is one hundred eighty degrees, so that the clockwise and counterclockwise rotation strokes of the rotary housing on the handle shaft 100 are zero degrees to ninety degrees, i.e. the stroke of the bending working portion of the soft lens is controlled to be the above-mentioned stroke.

As an optional implementation manner of this embodiment, an angle mark 130 is disposed at an end of the handle portion 200 near the rotary cover 110, and an orientation mark 131 is disposed on the rotary cover 110, where the orientation mark 131 matches with the angle mark 130.
