Abstract
The invention relates to an endoscope catheter moving pushing device, which comprises a membrane tube, an endoscope catheter main body and handle rods, wherein the endoscope catheter main body is provided with annular membrane clamping bosses, the inner end of the membrane tube is sealed and fixedly arranged on the endoscope catheter main body, the outer end of the membrane tube is connected with liquid injection seats which are positioned behind the annular membrane clamping bosses, a membrane clamping ring is arranged in front of each annular membrane clamping boss, the membrane tube is backwards folded around each membrane clamping ring to form an inner wall of the membrane tube and an outer wall of the membrane tube, and each handle rod is connected with each membrane clamping ring and is used for pulling each membrane clamping ring to clamp the inner wall of the membrane tube onto each annular membrane clamping boss. When the inner wall of the membrane tube is clamped on the annular membrane clamping bosses by the membrane clamping rings, the endoscope catheter main body is pushed to drive the inner wall of the membrane tube to extend forwards and convert into the outer wall of the membrane tube. The device has the advantage that when a catheter enters and exits an endoscope, the catheter is not in contact with the cavity wall, so the damage or pulling of the cavity wall is avoided.
Description
Technical field
The present invention relates to a kind of endoscope's propulsion plant as medical apparatus and instruments.Be mainly used in the digestive tract such as intestinal, esophagus, stomach, trachea, the endoscope of ureter etc. imports.
Technical background
Existing endoscope directly contacts between endoscopic catheters with chamber wall (such as intestinal wall) in advancing, and is sliding friction mode each other.Its major defect is: in turnover endoscopic procedure, between conduit and chamber wall, frictional force is comparatively large, and strengthens along with the increasing of penetration depth, is easy to damage chamber wall mucosa; Conduit is comparatively large to chamber wall drag force, easily produces rigid contusion.Under serious conditions, because spasm causes splanchnoscopy to proceed.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of endoscopic catheters to move about propulsion plant, in turnover endoscopic procedure, does not contact between conduit with chamber wall, to avoid damage or to pull chamber wall.
In order to solve the problems of the technologies described above, present invention employs following technical scheme.
Endoscopic catheters is moved about propulsion plant, it is characterized in that: comprise film pipe and be provided with the endoscopic catheters main body of annular snap film boss; The inner of described film pipe is closed and is fixed in endoscopic catheters main body, and outer end is connected with the liquid injection seat being positioned at annular snap film boss rear; Annular snap film boss front is provided with a card zona, and card zona inflection formation film inside pipe wall and film pipe outer wall backward walked around by described film pipe; Also comprise and to be connected with card zona and for pulling card zona film inside pipe wall to be clamped on handlebar on annular snap film boss; When film inside pipe wall is clamped on annular snap film boss by card zona, promotion endoscopic catheters main body drives film inside pipe wall to extend forward and is converted into film pipe outer wall.
Also comprise the liquid shutoff being enclosed within endoscopic catheters main body slidably, this liquid shutoff is positioned at liquid injection seat rear; Be provided with telescopic tube between liquid shutoff and liquid injection seat, telescopic tube front end is connected with liquid injection seat; Described the inner is positioned at annular snap film boss rear, film pipe from the inner begin to extend back to turn up again after one section extend forward beyond annular snap film boss after extend back again after card zona turns up, outer end is connected with liquid injection seat; Closed lubricating fluid space is formed between film pipe and endoscopic catheters main body, between film pipe and telescopic tube and between the two membranes pipe walking around card zona in liquid injection seat front; Handlebar rear end passes from liquid shutoff.
The pipe outer wall of endoscopic catheters main body is provided with adhesive tape.
Good effect of the present invention is: in (1), turnover endoscopic procedure, do not contact, also can not produce relative sliding friction between conduit with chamber wall.In endoscope's advance and retreat process, utilize existing endoscope to act on film pipe, drive membrane pipe folds feed compensation and advances, and progressively extends and realizes retreating, and film pipe rolls along chamber wall and extends.Therefore avoid endoscope in advance and retreat process and, to the damage of chamber wall or pulling, achieve noninvasive test, alleviate patient suffering.
(2), endoscopic catheters main body is in all the time among lubricating fluid and runs, drag minimization, and it is more soft that catheter main body can do.
(3), endoscope can directly entirety exit, and improves and checks and the efficiency of operation.
(4), endoscope main body drive membrane pipe folds feed compensation and advances, and therefore the turnover process of endoscope by the mechanism such as sacculus, sucker, thus need not simplify endoscope structure, correspondingly increases sight glass cavity free space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the planform schematic diagram of endoscopic catheters main body of the present invention.
Detailed description of the invention
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
As Fig. 1, basic structure of the present invention is as follows: comprise film pipe 1 and be provided with the endoscopic catheters main body 9 of annular snap film boss 3; The inner 4 of described film pipe 1 is closed and is fixed in endoscopic catheters main body 9, and outer end is connected with the liquid injection seat 5 being positioned at annular snap film boss 3 rear; Convex 3 fronts of annular snap film are provided with a card zona 2, and card zona 2 inflection formation film inside pipe wall and film pipe outer wall backward walked around by described film pipe 1; Also comprise and to be connected with card zona 2 and for pulling card zona 2 film inside pipe wall to be clamped on handlebar 11 on annular snap film boss 3; When film inside pipe wall is clamped on annular snap film boss 3 by card zona 2, promotion endoscopic catheters main body 9 drives film inside pipe wall to extend forward and is converted into film pipe outer wall.
According to this basic structure, in progradation, endoscopic catheters main body 9 except camera lens position is in all the time within film pipe 1 and does not contact with chamber wall, and extended forward by film inside pipe wall and be progressively converted into film pipe outer wall, achieve hurtless measure operation endoscopic catheters being advanced to inspection, operative site.
Still as Fig. 1, the concrete structure of the embodiment of the present invention is: it comprises endoscopic catheters main body 9, and endoscopic catheters main body 9 is provided with annular snap film boss 3.Also comprise and to be enclosed within outside endoscopic catheters main body 9 and to be positioned at the card zona 2 in annular snap film boss 3 front.Also comprise and to be enclosed within outside endoscopic catheters main body 9 and to be positioned at the liquid injection seat 5 at annular snap film boss 3 rear, liquid injection seat 5 is provided with liquid injection port.Also comprise the liquid shutoff 10 being enclosed within endoscopic catheters main body 9 slidably, this liquid shutoff 10 is positioned at liquid injection seat 5 rear.Be provided with telescopic tube between liquid shutoff 10 and liquid injection seat 5, telescopic tube described in the present embodiment is socketed to form successively by A sleeve pipe 6, B sleeve pipe 7 and C sleeve pipe 8 three tube units, realizes integral telescopic, also can arrange the tube unit of more than level Four.Described telescopic tube can also be whole piece extension type flexible pipe, such as flexible metal conduit.
