Abstract
The utility model relates to the field of medical instrument technology, more particularly to a kind of flexible sacculus dilating catheter in head, using a piece drawing silk of installation in sacculus, the distal end of drawing silk is fixed together with sacculus head, proximal end by pulling drawing silk keeps sacculus head flexible, to reduce the contact surface and active force of sacculus utricule and lift pincers device, reduces the risk that utricule is scratched, structure is simple, and it is convenient to operate.
Description
Technical field
The utility model relates to the flexible sacculus dilating catheters of the field of medical instrument technology more particularly to a kind of head.
Background technique
ERCP operation is done under duodenoscope when expanding to nipple, sacculus dilating catheter needs the lift pincers in scope
Under device lifting status, expansion position is got to after being bent utricule.Existing sacculus dilating catheter is under by lifting status
Lift when clamping device, since lift pincers device is metal material, utricule is easy to be scratched, can not fill, seriously affect procedure.
Utility model content
Technical problem to be solved by the utility model is: being easy to solve utricule in the prior art by lift pincers device scuffing
Technical problem, the utility model provide a kind of flexible sacculus dilating catheter in head.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of flexible balloon expandable in head is led
Pipe, including inner catheter, outer tube, sacculus and drawing silk, inner catheter is through in the inner cavity of the outer tube, the distal end of the inner catheter
Fixation is mutually sealed across the sacculus and with the distal end of the sacculus, the proximal end of the sacculus and the distal end fixing seal of outer tube connect
Connect, between inner catheter and sacculus, the distal end of drawing silk is fixedly connected the drawing silk with the distal end of sacculus, drawing silk it is close
End sequentially passes through sacculus and outer tube, and stretches out the proximal end of outer tube.The utility model is used installs a drawing silk in sacculus, leads
One end of wire drawing is fixed together with sacculus head, and the other end by pulling drawing silk makes sacculus head-bent, to reduce
The contact surface and active force of sacculus utricule and lift pincers device, reduce the risk that utricule is scratched.
Preferably, being also arranged with development mark, the development flag bit for the ease of surgical procedure, on the inner catheter
In in sacculus.
The utility model has the beneficial effects that the flexible sacculus dilating catheter in the head of the utility model, using in ball
A piece drawing silk of intracapsular installation, distal end and the sacculus head of drawing silk are fixed together, and the proximal end by pulling drawing silk makes ball
Capsule head is flexible, to reduce the contact surface and active force of sacculus utricule and lift pincers device, reduces the risk that utricule is scratched, knot
Structure is simple, and it is convenient to operate.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram before the flexible sacculus dilating catheter bending in the utility model head.
Fig. 2 is the flexible sacculus dilating catheter in the utility model head structural schematic diagram after bending.
In figure: 1, inner catheter, 2, outer tube, 3, sacculus, 4, drawing silk, 5, development mark.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
It as illustrated in fig. 1 and 2, is the utility model optimum embodiment, a kind of flexible sacculus dilating catheter in head, including
Inner catheter 1, outer tube 2, sacculus 3 and drawing silk 4, through in the inner cavity of outer tube 2, the distal end of inner catheter 1 passes through described inner catheter 1
Sacculus 3 simultaneously mutually seals fixation, the proximal end of sacculus 3 and the distal end fixed seal connection of outer tube 2 with the distal end of the sacculus 3, drawing
4 between inner catheter 1 and sacculus 3, the distal end of drawing silk 4 is fixedly connected silk with the distal end of sacculus 3, the proximal end of drawing silk 4 according to
It is secondary to pass through sacculus 3 and outer tube 2, and stretch out the proximal end of outer tube 2.Development mark 5, the development mark 5 are also arranged on inner catheter 1
In sacculus 3.
In use, it is mating with endoscope, dilation therapy is expanded or assisted for respiratory tract or Digestive Tract Stenosis.Specifically,
By pulling drawing silk 4, so that 3 head-bent of sacculus, so that the contact surface and active force of 3 utricule of sacculus and lift pincers device are reduced,
Reduce the risk that utricule is scratched.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
