Detailed description of the invention
This controllable bending nasal cavity Special ball ductus bursae as Figure 1-3, comprise union joint 1, control handle 2, can bend pipe 4, sacculus 5 and conduit 3, it is characterized in that:
A. described can bend pipe 4 be one by interior pipe 41, intervalve 42 and outer tube 44 3 layers combination body nested against one another, and the far-end of this described combination body is a flexible pipeline section; Described flexible pipeline section is provided with by a section of the position, body leading section being arranged on interior pipe 21 and intervalve 22 body be nested being uniformly distributed, having pipe otch A and intervalve otch B in certain length and width and forms; Being in the body of bend pipe near-end to be straight tube body, and described straight body portion to be directly set in control handle 1 and to communicate with union joint 1;
B. conduit 3 is nested with forms composite pipe body by leading interior pipe 31 and leading outer tube 32, and its far-end body is furnished with sacculus 5, and its near-end composite pipe body penetrates can until be connected with corresponding joint in control handle 2 in the interior pipe 41 of bend pipe 4 inner chamber respectively;
C. described control handle 2 comprises handle 11 and Knob mechanisms, and described handle 21 is fixedly connected with the conduit 3 penetrating handle 11 by positioning sleeve 24; Described Knob mechanisms comprises the knob 22, cutting ferrule 23, the alignment pin 24 that are located at handle 11 rear portion, and described knob 22 is nested with on cutting ferrule 23, and being connected and composed by helicitic texture between the two can the drives structure of bend pipe 4 front end bending section body; Described cutting ferrule 23 is nested with on the cylinder at handle rear portion, is located by connecting by alignment pin 24, two space washers 25 and cutting ferrule.
Described interior pipe 41 and intervalve 42 are metal tube, described interior pipe 41 and intervalve 42 far-end are all provided with the pipe otch of one section of certain length and width, and the pipe otch A411 that described interior pipe 41 is arranged is arranged towards the direction towards the opposite with the pipe otch B421 on described intervalve 42.
Described conduit 3 is formed by leading interior pipe 31 and leading outer tube 32, and conduit 3 runs through the inner chamber of control handle 2 and interior pipe 41, and far-end is connected with sacculus 5, and the other end is connected with union joint.
Described union joint 1 is provided with joint A11, joint B12 and full interface 13, wherein said joint A11 is bonding with leading interior pipe 31, described joint B12 is bonding with leading outer tube 32, and described joint A11 and joint B12 coaxially communicates, described full interface 13 and joint A11, joint B12 is vertical communicates.
The near-end 51 of described sacculus 5 with lead outer tube 32 and be connected, the far-end 52 of described sacculus with lead interior pipe 31 and be connected; The inner chamber of described sacculus 5 communicates with full joint 13.
Described interior pipe 41, intervalve 42 are metal material materials and parts, and weld with head end metal tube 43 simultaneously.
Described conduit 3 is that nylon, polyamide or polyurethane material make.
Described sacculus is that nylon, polyamide, polyurethane or PET material make.
This technical scheme devises a set of changing the mechanism innovatively, converts rotary motion to rectilinear motion, converts rectilinear motion to curvilinear motion again.
The operation principle of this controllable bending catheter sheath device is as follows:
First sacculus is roughly placed on the diseased region of patient's nasal cavity, after rotating clockwise knob 22, drives cutting ferrule 23, alignment pin 24, space washer 25 and interior pipe 41 axially to move upward together.Due to interior pipe 41, intervalve 42 is welded on head end metal tube 43 simultaneously, and intervalve is fixed in handle 21 and cannot moves, therefore interior pipe is obstructed when axially moving upward, under the effect of traction force, interior pipe 41 has one end of otch to start to bend, and bending direction is the opposite direction of interior pipe otch.
Interior pipe 41 drives intervalve 42 to bend.The direction that intervalve bends is the equidirectional of intervalve otch.After intervalve is bending, otch receives compression, and finally, after otch is compressed to the limit, intervalve can not bend again.This also determines the maximum bend angle of the present invention/invention.
Intervalve 42 drives outer tube 43 to bend together.Because outer tube is that macromolecular material has certain elasticity, therefore can passively bend.
Thus foley's tube can control its bending angle by the rotation of knob, make sacculus coaxial with the nasal cavity mouth needing to treat, then advance sacculus gently, make it reach the nasal sinuses mouth needing expansion.
Subsequently, filling device or equipment by full interface connecting the pressure that normal saline or contrast agent are housed, making inflation by operating this device, reaching treatment requirements of operation.
Above are only basic technical scheme and the embodiment of the present invention's proposition, the present invention is not limited in the content of embodiment.To those skilled in the art, various change and change can be produced within the scope of the inventive method, belonging to any change of doing in the present invention's main intention category and change all belongs to scope.
