Abstract
The utility model belongs to the technical field of the medical appliance. In order to overcome the technical defects existing when the traditional balloon dilator is used for carrying out the dilation therapeutic process on the human body tract, the utility model provides the mechanical balloon dilator with the advantages of easiness in operation, small patient pain and good therapeutic effect. The mechanical balloon dilator comprises a catheter, wherein the catheter is provided with a blind end; the pipe wall of the blind end of the catheter is evenly provided with three balloon dilation holes; the inner pipe wall of the blind end of the catheter is adhered with one layer of ultrathin balloon wall; and after the balloon wall is stressed, the balloon wall is swelled out from the balloon dilation holes to form a balloon. The medical balloon dilator disclosed by the utility model is favorable for the tract peristalsis of a diseased region, and can also perform the therapeutic effect on the recovery therapy.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically is meant a kind of being used under the endoscope the narrow medical balloon dilatation catheter of treating of body cavities.
Background technology
Body cavities, for example esophagus etc. is normal because disease or operation become narrow, during treatment, is mostly to adopt the endoscope location to insert balloon dilatation catheter then and carries out dilation therapy.Present balloon dilatation catheter is that sacculus is set on conduit, under the guiding of endoscope, arrives diseased region and expands, because balloon diameter is bigger; The one, can not pass through endoscope's biopsy channel hole; During insertion, dilator need insert with endoscope at twice, brings misery to patient; The 2nd, sacculus forms fully at expansion position and tract wall that sealing contacts, and the wriggling of tract receives sacculus and limits, and is unfavorable for the efficient recovery that has of tract.
Summary of the invention
For overcoming present balloon dilatation catheter in the technological deficiency of body cavities being carried out exist in the dilation therapy process, this utility model provides a kind of processing ease, less patient suffering is little, therapeutic effect is good medical balloon dilatation catheter.
The technical scheme that this utility model adopts is: medical balloon dilatation catheter; Comprise a conduit; Conduit is provided with a cecum; It is characterized in that: described conduit evenly is provided with three balloon expandable holes on the tube wall of its cecum, on the inner pipe wall of conduit cecum, adheres to the ultra-thin balloon wall of one deck, and balloon wall is under pressure afterwards to be swelled by the balloon expandable hole and forms sacculus.
After adopting technique scheme, its overall diameter was not a conduit diameter when balloon dilatation catheter was worked, and can directly get into diseased region through endoscope's biopsy channel hole with endoscope, had reduced the insertion number of times, had alleviated less patient suffering; Balloon dilatation catheter owing to have the partition of catheter wall between the sacculus body, to form the space between the sacculus body that the conduit cecum forms, helps the wriggling of diseased region tract when balloon expandable simultaneously, can play therapeutic effect to resuming treatment of tract.
Description of drawings
Accompanying drawing 1 is the sketch map as a result of this utility model.
Accompanying drawing 2 be among Fig. 1 A-A to cutaway view.
Accompanying drawing 3 is this utility model user mode sketch map.
Among the figure, 1, conduit, 2, the balloon expandable hole, 3, balloon wall, 4, sacculus, 5, the conduit cecum.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
As shown in Figure 1, medical balloon dilatation catheter comprises a conduit 1, and the closed cecum 5 that forms of conduit one end is provided with balloon expandable hole 2 on the tube wall of conduit cecum.
As shown in Figure 2, on the inner pipe wall of conduit cecum 5, adhere to the ultra-thin balloon wall 3 of one deck, can find out that by this figure in the present embodiment, balloon expandable hole 2 is set to 3, catheter wall forms supporting rib between the sacculus supported hole.
As shown in Figure 3, after injecting liquid or inflation in the conduit, manifold pressure increases, and the extruding back that is under pressure of the balloon wall on conduit cecum inner pipe wall was swelled by the balloon expandable hole and formed sacculus 4 this moment.
Can find out that in conjunction with Fig. 2 and Fig. 3 balloon wall forms 3 utricules outside the balloon expandable hole of extruding back at conduit that be under pressure, because the partition of catheter wall is arranged between the utricule; Between utricule, can form three spaces; Carrying out balloon expandable when treatment, form the space between body cavities wall and the sacculus like this, help the wriggling of tract and unobstructed; Avoid tract to entirely shut, can play positive role resuming treatment of tract.
