Abstract
The present invention is that a kind of guiding noinvasive advances film pipe device, and inner mold tube assembly and adventitia pipe assembly have a film pipe separately, and film pipe is made up of the inner and outer tubes be nested together mutually, the same side end looping Sealed sandwich sealed to each other of inner and outer tubes; Under Sealed sandwich topping up state, the tube wall of two film pipes contacts with each other, to ensure that the inwall driving adventitia pipe assembly when the displacement of inner mold tube assembly extends; Guiding rope penetrates between inner mold tube assembly and adventitia pipe assembly from adventitia pipe assembly rear end, from turning back outside adventitia pipe assembly to adventitia pipe assembly rear after passing from adventitia pipe assembly front end.Fltting speed is controlled, takes out propulsion plant instantaneously, checks the operating time, and do not produce sliding friction, to realize noninvasive test between propulsion plant and chamber wall (such as enteral wall) to shorten.In addition, after exiting propulsion plant, in patient body, leave operation path, realize the multichannel of operating theater instruments turnover.
Description
Technical field
The present invention relates to a kind of guiding noinvasive as medical apparatus and instruments and advance film pipe device, be mainly used in advancing inspection and operation equipment, such as advance capsule endoscopic to implement digestive tract examining, advance operating theater instruments in diseased region sampling or operation.
Technical background
The endoscopic existing mode of intestinal generally comprises oral capsule capsule endoscope and enteroscope two kinds.Patient's oral capsule capsule endoscope (intelligent capsule digestive tract endoscopic system, also known as Medical wireless scope), capsule endoscopic runs naturally through digestive tract, and pickup image data in digestive tract, finally discharge from anus.Its shortcoming is capsule endoscopic long operational time in intestinal, is generally 5 ~ 20 hours, even longer.In addition, because capsule endoscopic relies on intestinal peristalsis promoting to run, and intestinal peristalsis promoting has not feature at the uniform velocity, easily loses the opportunity of capturing some emphasis picture position instantaneously.Three, meet intestinal that larger tumor or other reason cause smooth time, cannot implement to check.Existing enteroscope, the double bolloon electron mirror of such as Japanese fuji energy company, stacked structure before adopting, is directly enclosed within small intestinal on trocar sheath during use, arrives small intestinal deep by intestines accumulation mode.Its shortcoming is comparatively large to intestinal body drag force, adds the distress level of patient, often stops because of spasm checking.Also have checking process length consuming time, the shortcomings such as operation easier is large, full small intestinal endoscopy needs 3 hours simultaneously.
In addition, limit by operation path, in cavity, diseased region conveying operating theater instruments, takes out cut pathological tissues (such as polyp), and more difficult to diseased region administration.Such as when operation needs hemostasis simultaneously, for another example when operation needs congestion to take out simultaneously, because passage is single, therefore cannot carry out simultaneously.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of guiding noinvasive to advance film pipe device, fltting speed is controlled, take out propulsion plant instantaneously, check the operating time to shorten, and do not produce sliding friction, to realize noninvasive test between propulsion plant and chamber wall (such as enteral wall).In addition, after exiting propulsion plant, in patient body, leave operation path, realize the multichannel of operating theater instruments turnover.
In order to solve the problems of the technologies described above, present invention employs following technical scheme.
Guiding noinvasive advances film pipe device, it is characterized in that: comprise inner mold tube assembly and be enclosed within the adventitia pipe assembly outside inner mold tube assembly; Inner mold tube assembly and adventitia pipe assembly have a film pipe separately, and described film pipe is made up of the inner and outer tubes be nested together mutually, the same side end looping Sealed sandwich sealed to each other of described inner and outer tubes; Under Sealed sandwich topping up state, the tube wall of two film pipes contacts with each other, to ensure that the inwall driving adventitia pipe assembly when the displacement of inner mold tube assembly extends; Also comprise guiding rope, guiding rope penetrates between inner mold tube assembly and adventitia pipe assembly from adventitia pipe assembly rear end, from turning back outside adventitia pipe assembly to adventitia pipe assembly rear after passing from adventitia pipe assembly front end.
Support propulsion assembly is installed in ring packing interlayer; Described inner mold tube assembly also comprises the inner and is connected with described film pipe respectively, and through film tube hub, outer end is positioned at three stay cords at film pipe rear, and the circumference on film pipe of the junction point between three stay cords and film pipe is uniform; Described adventitia pipe assembly also comprises the inner and is connected with described film pipe respectively, and through film tube hub, outer end is positioned at three stay cords at film pipe rear, and the circumference on film pipe of the junction point between three stay cords and film pipe is uniform; The film pipe outer wall of adventitia pipe assembly is provided with and is filled with hole for what be filled with liquid or gas or lubriation material to ring packing interlayer.
Described support propulsion assembly comprises support ring and is connected with support ring and moves towards the support with film tubular axis line parallel, and back-end support is connected with handle.
Described film pipe is prepared from according to one of following two kinds of methods: first method: the film material pipe getting one section of both ends open, an one opening is turned up and is pulled to its another opening, two openings are closed mutually and are connected, and form ring packing interlayer between the section of turning up and inner segment; Second method: by two sections of film material pipe boxes together, same one end of two sections of film material pipes is closed mutually and is connected, and forms ring packing interlayer between two sections of film material pipes.
Good effect of the present invention is: (1), fltting speed are fast, significantly shortens and checks the operating time; (2), between propulsion plant and chamber wall do not produce sliding friction, achieve noninvasive test.(3), when implementing intestinal (such as small intestinal) sight glass and checking, to mesentery without pull effect, enterospasm therefore can not be caused to occur.(4), as needed intestines to perform the operation, exited by inner mold tube assembly, adventitia pipe assembly stays operative site, and extracted out by the liquid in the topping up interlayer of adventitia pipe assembly, adventitia pipe assembly is as operation path.(5) guiding rope, is utilized from adventitia pipe assembly center, operating theater instruments can be transported to operative site; Also operating equipment or medicament can be imported by the guiding rope outside adventitia pipe assembly to operative site.Be formed centrally a passage in adventitia pipe assembly, as Article 2 passage outside adventitia pipe assembly, two passes uses simultaneously, is convenient to multiple apparatus and coordinates operation, and convenient drug administration.Two manual tasks of operation process can be realized.
