Abstract
A kind of two-tube lacrimal passage drainage tubes, using the catheter end and drainage tube body of integral structure, it is connected using the transition of size gradation between catheter end and drainage tube body, it is made of flexible different material between catheter end and drainage tube body, it is to be more prone to so that two-tube lacrimal passage drainage tubes is imported superior canaliculus with lower lacrimal canaliculi, easy to operate.
Description
Technical field
The utility model is related to the field of medical instrument technology, and in particular to a kind of two-tube lacrimal passage drainage tubes.
Background technology
Obstruction of lacrimal canaliculus is a kind of common lacrimal passage disease, has clinically been had at present using two-tube single step artificial tear duct
It is implanted into the therapy performed the operation, but in above-mentioned treatment, needs guiding tube being first inserted into meatus nasi inferior, then try from meatus nasi inferior
It pulls in nasal cavity.And original guiding tube is too hard, is not easy to pull in nasal cavity, makes troubles to surgical procedure, increases the pain of patient
It is bitter.
Therefore, a kind of two-tube lacrimal passage that can have not only imported meatus nasi inferior but also easily pull in nasal cavity from meatus nasi inferior is also lacked at present to draw
Flow tube provides facility to block patient for lacrimal passage.
Invention content
In order to solve the deficiencies in the prior art, the utility model provides a kind of two-tube lacrimal passage drainage tubes.
The utility model use technical solution be：A kind of two-tube lacrimal passage drainage tubes, including drainage tube body, it is described
Drainage tube body both ends be equipped with conduit device, the conduit device includes catheter end and the guiding that is plugged in catheter end
Needle, the catheter end are an integral structure with drainage tube body, and size is used between the catheter end and drainage tube body
The transition of gradual change connects, and the guid needle is detachably connected with catheter end, the catheter end and drainage tube chamber body phase
Even.
The junction of the drainage tube body and catheter end is additionally provided with pin hole, and the guid needle is plugged on across pin hole
In catheter end.
The catheter end of the integral structure and the flexibility for the material that catheter end uses in drainage tube body are more than drainage
The flexibility of the material of tube body.
The drainage tube body is made of medical PP materials, and the catheter end is made of polyurethane material.
The end of the guid needle is additionally provided with shank, and the shank is located at outside catheter end.
The end of the catheter end is closed arc-shaped.
The length of the drainage tube body is 30cm, outer diameter 0.65mm.
The catheter end length is 13cm, outer diameter 1mm, internal diameter 0.6mm.
The utility model has the beneficial effects that：The utility model provides a kind of two-tube lacrimal passage drainage tubes, using integral type
The catheter end of structure and drainage tube body, are connected between catheter end and drainage tube body using the transition of size gradation, catheter end
It is made of flexible different material between drainage tube body, two-tube lacrimal passage drainage tubes is made to import superior canaliculus and lower lacrimal canaliculi
It is to be more prone to, it is easy to operate.
