Abstract

The utility model relates to a silica gel lacrymal passage expanding stent, which comprises a silica gel pipe (1), a pure titanium sheet metal (2), and a strip of nylon wire (3). The utility model is characterized in that the pure titanium sheet metal (2) is coated on the silica gel pipe (1) which is a long flexible pipe with a shape of cone, and one end of the nylon wire (3) is fixedly connected with the cone-shaped sharp portion of the long flexible pipe. Compared with the prior art, the utility model has simple structure and small size, and the treatment of lacrymal passage blocking has the effects of no scar on surface, less sufferings for patients, simple operation, reliable curative effect, and low recurrence rate through applying the utility model.

Description

Description silica gel lacrimal passage expandable stent

This utility model relates to a kind of silica gel lacrimal passage expandable stent, relates to a kind of lacrimal passage expandable stent that is coated with the pure titanium metal layer specifically.Belong to medical body implant.

At present, the treatment of obstructed lacrimal passage (especially going up obstructed lacrimal passage) is the clinical problem that the ophthalmologist constantly explores concern always.Treatment obstructed lacrimal passage, elimination epiphora miseries such as dacryocystorhinostomy, lacrimal passage intubation dilatation, lacrimal passage circulation art (laser, electricity coagulate), lacrimal passage justice pipe implantation all have certain curative effect, but because the shape of existing lacrimal passage intubation and lacrimal passage justice pipe, with and structure structure reasonable inadequately, so exist face leave over operation cicatrix, operation technique difficulty, easily recurrence, adopted pipe come off, various problems such as instrument and equipment costliness.In a word, the shape of the body implant of existing treatment obstructed lacrimal passage and structure structure thereof need further improvement.

The purpose of this utility model is to design a kind of silica gel lacrimal passage expandable stent that is coated with the pure titanium metal layer, to overcome the deficiencies in the prior art.

The purpose of this utility model is to realize like this, it is made up of silica gel tube (1), pure titanium metal layer (2) and nylon yarn (3), it is characterized in that: silica gel tube (1) is gone up parcel and is coated with pure titanium metal layer (2), silica gel tube (1) is taper Great Wall Software pipe, and the cone tip part of a termination of nylon yarn (3) and silica gel tube (1) is affixed.

This utility model compared with prior art, it is simple in structure, volume is little, utilizes it to make the treatment of obstructed lacrimal passage can reach facial no cicatrix, patient's misery is little, operation technique is easy, curative effect is reliable, relapse rate is low effect.

Below in conjunction with drawings and Examples this utility model is further specified:

Accompanying drawing is the whole sectional structure sketch map of this utility model.

Wherein: 1, silica gel tube, 2, the pure titanium metal layer, 3, nylon yarn.

Referring to accompanying drawing, it is made up of this utility model silica gel tube 1, pure titanium metal layer 2 and nylon yarn 3, described silica gel tube 1 is selected medical silica-gel for use, it is the method that adopts the vacuum plasma technical face to handle, parcel is coated with pure titanium metal layer 2 on silica gel tube 1, silica gel tube 1 is taper Great Wall Software pipe, and a termination of nylon yarn 3 and the cone tip part of silica gel tube 1 are affixed.
