Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.The application can realize with multiple different form, is not limited to the embodiment described by the present embodiment.There is provided the object of following detailed description of the invention to be convenient to this to application disclosure clearer understanding thoroughly, wherein the words of the indicating position such as upper and lower, left and right is only for shown structure position in respective figure.
Embodiment one:
Please refer to Fig. 1 and 2, the present embodiment one provides a kind of snake bone pipe unit to save.
This unit joint comprises cylindrical shell 131 and journal stirrup 132.
In the middle part of this cylindrical shell 131, hollow forms interface channel.The barrel of cylindrical shell 131 has through hole 1312, and this through hole 1312 is along cylindrical shell 131 axially through barrel.The present embodiment one through hole 1312 is 4, can be run through by 4 steel wire ropes, for transmitting power, controls the bending of snake bone tube end unit joint.
Journal stirrup 132 1 has two, is oppositely arranged on roof 1311.
And in other embodiments, journal stirrup 132 also can be fixed on other positions of cylindrical shell 131, such as sidewall.
The barrel of this cylindrical shell 131 is provided with for saving hinged the first location division coordinated with a rear unit, and journal stirrup 132 has for saving hinged the second location division coordinated with previous element.This first location division and the second location division are that decussation is arranged.
In the present embodiment one, the first location division is connecting hole 1314, second location division be opened on barrel is the radial pin 1321 arranged.
Certainly, in other embodiments, the first location division also can be the radial pin arranged, and the second location division also can adopt connecting hole.
In the present embodiment one, cylindrical shell 131 and journal stirrup 132 are integrated injection mo(u)lding, therefore cylindrical shell 131 and journal stirrup 132 all have certain plastic deformation ability, a wherein journal stirrup saved can be extruded by a hands during installation, another hands extrudes the cylindrical shell of another joint, two joint portion occurs after deformation, makes the pin on journal stirrup enter connecting hole on another joint cylindrical shell.Remove extruding force, joint portion recovers deformation, namely completes the connection of adjacent two joints, free-handly under the prerequisite not by any instrument can complete installation, assemble more for convenience.
Certainly, in other embodiments, cylindrical shell 131 or journal stirrup 132 also can be selected to adopt separately made of plastic, and then the two is fixed together.
Further, reserve between the most outer of roof 1311 of journal stirrup 132 and cylindrical shell 131 and dodge space, this dodges the sidewall of space for accommodating cylindrical shell 131, therefore, after on the journal stirrup 132 that the cylindrical shell 131 of unit joint is installed to another unit joint, cylindrical shell 131 outer wall of two unit joints can be made to be positioned on the same face.
Further, please refer to Fig. 2, the corresponding journal stirrup 132 of cylindrical shell 131 inwall is provided with depressed part 1313, the thickness of this depressed part 1313 is more than or equal to journal stirrup 132 thickness, journal stirrup 132 is installed to after in depressed part 1313, and journal stirrup 132 outermost can be consistent with cylindrical shell 131 inwall or be hidden in depressed part 1313.
Further, the top of journal stirrup 132 can also have arc outer 1322, and as shown in Figure 1, corresponding depressed part 1313 correspondence also has arc outer 1316.
Save after being connected for making some unit, unit joint local inclination angle can reach specified value, and the diapire 1315 of joint portion cylindrical shell 131 has makes a concession angle a, and such as wedge shape makes a concession angle, as shown in Figure 3, greatly can increase angle of bend.
Embodiment two:
Please refer to Fig. 3, the present embodiment two provides a kind of snake bone pipe.
This snake bone pipe comprises some unit joint.
This some unit joint is connected with the second location division by the first location division successively.Wherein joint 110 headed by first unit joint, last unit joint is periproct 120.Saving 130 at the head unit saved between 110 and periproct 120 can adopt the unit as shown in embodiment one to save.Middle unit saves 130 selectable number and selects, as 14 joints (only exemplary in Fig. 3 mark out two).
During connection, be connected by the connecting hole that previous element saves with the journal stirrup that a rear unit saves 130, the junction of adjacent two unit joint 130 is formed as joint.
This head joint 110 and periproct 120 are connected in stem and afterbody respectively.First joint 110 is for carrying image-forming module, biopsy channel outlet and gas injection filling outlet, and periproct 120 is for connecting endoscope tube.Wherein first joint 110 and periproct 120 also can adopt the unit joint structure shown in embodiment one, or also according to the miscellaneous part shape that will connect, the joint of unit shown in embodiment one structure can be out of shape, as shown in Figure 3.Connecting mode between first joint 110 and periproct 120 and temporary location saves is also identical with the connecting mode that temporary location saves each other.
Because unit joint is adopted made of plastic, therefore cylindrical shell and journal stirrup all have certain plastic deformation ability, and can extrude a wherein journal stirrup saved by a hands during installation, another hands extrudes the cylindrical shell of another joint, two joint portion occurs after deformation, makes the pin on journal stirrup enter connecting hole on another joint cylindrical shell.Remove extruding force, joint portion recovers deformation, namely completes the connection of adjacent two joints, free-handly under the prerequisite not by any instrument can complete installation, assemble more for convenience.
Embodiment three
Please refer to Fig. 4, the present embodiment three provides a kind of telecontrol equipment for endoscope.
This telecontrol equipment comprises snake bone pipe 100, wire driving member 200, spring protecting sleeve pipe 300 and flexible pipe 400.
This snake bone pipe 100 can adopt structure as shown in embodiment two.
Wherein, the head of wire driving member 200 one end and snake bone pipe 100 save 110 or other unit being positioned at snake bone pipe front portion save fixing, the other end extends from periproct 120 through the through hole on unit joint 130 successively.Utilize the position of first joint 110 on this Linear transmission part adjustable snake bone pipe 100, realize rotating.
This Linear transmission part can adopt steel wire rope.
This spring protecting sleeve pipe 300 is set on wire driving member 200, is formed spacing to Linear transmission part, ensures that its draft travel change when bending of Linear transmission part is little, reduces Linear transmission part friction simultaneously, thus reduce the pull strength of Linear transmission part.
Flexible pipe 400 is set in Linear transmission part and spring protecting sleeve pipe 300, protects.
Curved part of endoscope controls to adopt wire rope transfers power, due to endoscope in working order time, bending situation can be there is in flexible pipe 400, tension force suffered by steel wire rope forms the normal pressure to bending place interior angle, if steel wire rope directly rubs to the larger rubber hose 400 of coefficient of friction, then there will be stuck phenomenon, four steel wire ropes of traction snake bone pipe 100 are allowed to run through from metal spring protecting pipe 300 respectively, the force of sliding friction of bending place can be effectively reduced, after being entangled by the spring protecting sleeve pipe 300 that caliber is less in addition, the radial space of steel wire rope is limited, can ensure that draft travel changes in allowable error.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
