Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 to 3 schematically show a snake bone structure of an endoscope according to an embodiment of the present invention.
As shown in FIGS. 1 to 3, the snake bone structure is a joint assembly composed of a plurality of joints 21 which are clamped with each other.
The joint 21 includes a joint ring 210, two snap legs 211, and two snap slots 212.
The two latching legs 211 are arranged opposite to each other on one end face of the joint ring 210, and the two latching slots 212 are arranged opposite to each other on the other end face of the joint ring 210. The connecting line of the two clamping columns 211 is perpendicular to the connecting line of the two clamping slots 212, the clamping slots 212 are open circular notches, the clamping columns 211 are cylindrical, the clamping columns 211 are matched with the clamping slots 212 in shape and position, and the diameter of each clamping column 211 is slightly larger than the opening width of each clamping slot 212.
The inner wall of the joint ring 210 is provided with two drawing through holes 213 along the axial direction, and the drawing through holes 213 are opposite and are located on the connecting line of the two clamping columns 211. A pull cord may be threaded through the pull through hole 213.
When the snake bone structure is spliced, the clamping column 211 of one joint 21 can be directly vertically pressed into the clamping groove 212 of the adjacent joint 21 for connection, and the clamping mode of vertical pressing does not cause the joint ring 210 to generate transverse deformation and is convenient to install.
In this embodiment, the drawing through hole 213 is cylindrical, is located on the inner wall of the joint ring 210, extends from the joint ring 210 to one end surface of the joint ring 210, and the clamping column 211 is arranged on the outer side surface of the free end of the drawing through hole 213. The arrangement enables the clamping column 211 to have a certain distance from the end surface of the joint ring 210, so that the space for relative rotation of two adjacent joints 21 can be increased, and the bending angle of the snake bone structure is increased. In other embodiments, the distraction via 213 can also be disposed on the outer wall of the joint ring 210.
The end face of the joint ring 210 at the end provided with the locking groove 212 has two oppositely arranged protrusions 214, and the locking groove 212 is located at the free end of the protrusion 214. This arrangement allows for increased rotation of adjacent joints 21 and also allows for more flexibility in the movement of the snake bone structure. The end surface provided with the catching post 211 may be a flat surface. In the present embodiment, the protrusion 214 has a V-shape, and the angle of the V-shape and the number of joints 21 determine the magnitude of the turning angle of the snake bone structure. In other embodiments, the protrusion 214 may also be semi-circular.
The joint 21 can be an integral injection molding structure, and the product has light weight and low cost.
FIG. 4 is a schematic view showing the positional relationship of adjacent joints in a state where a traction rope is slack in the snake bone structure of the endoscope shown in FIG. 1.
As shown in fig. 4, when the traction rope is in a slack state, the joint loops 210 of the two adjacent joints 21 in the snake bone structure are parallel to each other, and at this time, the snake bone structure is not bent, and the lead end portion 10 connected to the tip end of the snake bone structure is not changed in direction.
FIG. 5 schematically shows the positional relationship of adjacent joints in the serpentine bone structure of the endoscope shown in FIG. 1 in a state where one traction cord is tensioned.
As shown in fig. 5, when a traction rope inserted into the joints 21 is tensioned, one joint 21 rotates in the axial direction of the locking column 211 thereof, and the angle of the joint ring 210 of the adjacent joint 21 becomes smaller. When the plurality of joints 21 are rotated relative to the adjacent joints 21 in the axial direction of the snap legs 211 thereof, the serpentine bone structure is bent.
The snake bone structure can be provided with four traction ropes 711, the upper bending direction and the lower bending direction are controlled by two ropes, and the left bending direction and the right bending direction are controlled by two ropes, so that the bending direction of the snake bone structure can be controlled by 360 degrees.
Fig. 6 schematically shows a state of use of the snake bone structure of the endoscope according to an embodiment of the present invention.
As shown in fig. 6, the joint tail end 23 of the joint assembly and the hose portion 30 can be adhered by glue to realize rigid connection of the snake bone structure and the hose portion 30, and the planar end of the joint ring 210 at the joint tail end is provided with a protruding structure 23 for connecting the hose portion 30. Haulage rope fixing base 22 is located snake bone structure front end, and haulage rope fixing base 22's step face and guide's tip 10 are connected, and the tail end of haulage rope fixing base 22 passes through the buckle and connects with joint assembly, realizes snake bone structure and guide's tip 10's location and connects. The outer portion of the snake bone structure can be sleeved with a smooth elastic membrane, the snake bone structure is soft in material and has certain flexibility, the front end of the snake bone structure and the end cap of the guide end portion 10 can be bonded through glue, and sealing of the snake bone structure is achieved.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
