Description

A kind of internally-arranged type lacrimal passage drainage tubes

Technical field

The utility model is related to technical field of medical instruments, more specifically, and the utility model is related to a kind of internally-arranged type tear Road drainage tube.

Background technology

Surgical stapling and implantation drainage tube support lacrimal wall should be carried out after Traumatic canaliculus disruption in time, to promote pipe Chamber formation and moulding effect, drainage tube need to be placed 2~3 months, to reduce the generation of the complication such as excessive tear.Current laceration of lacrimal canaliculus The conventional drainage tube of Disease Clinical mainly has two kinds of segmental epidural catheter and silicone tube.

Segmental epidural catheter puts tube method using single lacrimal nasolacrimal duct, and operation technique is easy, but its material is harder, often leads Cause the lacrimal broken ends of fractured bone to chip, its catheter tip, which need to be sutured, to be fixed on outside eyelid, influence outward appearance, easily cause unexpected de- pipe, security Difference.Silicone tube puts tube method frequently with double lacrimal nasolacrimal ducts, and silicone tube material is softer, and safety in utilization, aesthetic property are higher, still Due to tear house steward, drainage pipe diameter is reduced to a certain degree, so that weaken the supporting role to lacrimal to a certain degree, And operation needs repeatedly via intranasal application to operate, operating difficulty is high, and opereating specification is larger, damages serious to nasal membrane, increase infection Chance.And using single lacrimal nasolacrimal duct to put tube method, silica gel pipe end still needs to be fixed on outside eyelid.

Caused by tissue characteristics, puncta is narrow far beyond lacrimal, and tissue expansivity is small, and conventional lacrimal passage drainage tubes are complete Pipe diameter is almost consistent, and drainage tube need to be exposed to outside puncta during putting pipe, and puncta and lacrimal are expanded on an equal basis.It is this to draw The reason for damage that flow tube is formed to puncta is often postoperative excessive tear.During another Puncture Tube, drainage pipe choking puncta is excessive tear Main cause.

The utility model patent of Application No. 200920271235.9, it discloses a kind of stub pin type lacrimal passage support, leads to Cross and allow mozzle eyelid end to expand to prevent silicone tube to nasal cavity migration, but have and damage tear because the big end silicone tube of Peng is exposed The drawbacks of dot, with certain potential safety hazard.
