Abstract

The utility model relates to a flexible guiding system for lacrimal duct intubation, which comprises a catheter, a stainless steel needle and an irrigation connector. The catheter is flexible, the head end of the catheter is a blunt blind end and provided with a side hole, scales are marked on the catheter at an interval of 1cm, the inner diameter of the catheter is 1mm, the stainless steel needle is provided with the irrigation connector, and the head end of the stainless steel needle is a blunt cavity and can be directly irrigated. During surgery, the catheter is sleeved outside the stainless steel needle to have a hardness supporting function so as to be favorable for implanting the catheter into a lacrimal duct from a lacrimal point and then penetrating out via a naso-lacrimal duct, water is injected via the end of the lacrimal point to judge whether the catheter is implanted into the lacrimal duct or not, the catheter is hooked out via a nasal cavity, the exposed silicon blind end is cut off, then a linear silicon tube guide wire penetrates through the catheter, and the catheter guides a linear silicon tube to be implanted into the lacrimal duct. The flexible guiding system has the advantages that the diameter of the catheter is slightly larger than that of the linear silicon tube and smaller than that of a lacrimal canaliculi so as to be favorable for implanting the silicon tube, the flexible catheter and the blunt head end of the catheter can reduce damage of the lacrimal duct, prevents forming of a false duct and is easy to enter a lacrimal sac and the like, and the flexible guiding system effectively avoids damaging the mucous membrane of the inner wall of the lacrimal canaliculi or a dacryocyst, realizes safe surgery and is simple and convenient in operation.

Description

Soft lacrimal passage is put the pipe guidance system

Technical field

This utility model relates to a kind of medical medical apparatus and instruments, relates in particular to a kind of soft lacrimal passage of ophthalmology assistive device that is used for lacrimal surgery and puts the pipe guidance system.

Background technology

At present, it mainly is No. 9 spinal needles etc. of perforated metal lacrimal probe, soft type silica gel lumbar anesthesia pipe, the transformation of the way that lacrimal passage is put the pipe guidance system, exist guidance system complicated operation, the total inside pipe wall mucosa injury of lacrimal ductule/tear, lacrimal ductule by shortcomings such as puncta difficulty, nasal cavity hook pipe difficulties, still none cover ideal lacrimal passage really easy to operation, that wound is minimum is put the pipe guidance system, with the least possible wound artificial tear duct/support is implanted in the lacrimal passage smoothly.

The utility model content

This utility model is that a kind of soft lacrimal passage that is used for lacrimal surgery that redesigns at the deficiency of the guidance system existence of using in the present lacrimal surgery is put the pipe guidance system, and putting pipe for lacrimal passage provides a kind of new aid, is beneficial to the smooth implementation of operation.

The technical scheme in the invention for solving the technical problem is:

Soft lacrimal passage is put the pipe guidance system, and it comprises: conduit is formed with stainless pin two parts of band pintle; It is characterized in that: the conduit material soft and above be printed on scale, scale spacing is 1cm, internal diameter is 1mm, head end is blunt round cecum band side opening; The blunt circle of stainless pin head end, cavity and upper end have the pintle that washes interface, can directly wash by the flushing interface; In operation, sheathed catheter outside stainless pin, is played the hardness supporting role, be beneficial to conduit is implanted lacrimal passage by lacrimal point, pass through nasolacrimal duct; Through the water filling of lacrimal point end, judge whether conduit implants lacrimal passage; Conduit by ticking in the nasal cavity, is cut off the conduit cecum that exposes, then linear silicon sebific duct seal wire is passed conduit, under the guiding of conduit, the linear silicon sebific duct is implanted lacrimal passage.

The specific embodiment

As shown in Figure 1, a kind of soft lacrimal passage is put the pipe guidance system, and it comprises: stainless pin 2 two parts of conduit 1, band pintle; Wherein on the conduit 1 scale 1-1 is arranged, head end is blunt round cecum band side opening 1-2; Stainless pin 2 is divided into draw point 2-1 and flushing interface 2-2 two parts, and draw point 2-1 is cavity, the blunt circle of head end, stainless pin 2 upper end band flushing interface 2-2, and medical personnel can directly wash by flushing interface 2-2; It is outer that conduit 1 is enclosed within stainless pin 2.

Described soft lacrimal passage is put the pipe guidance system, and wherein conduit 1 is enclosed within outside the draw point 2, in operation, conduit 1 is enclosed within outside the stainless pin 2, plays the hardness supporting role, is beneficial to conduit 1 is implanted lacrimal passage by lacrimal point, passes through nasolacrimal duct; Through the water filling of lacrimal point end, judge whether conduit 1 implants lacrimal passage; Conduit 1 by ticking in the nasal cavity, is cut off conduit 1 cecum that exposes, then linear silicon sebific duct seal wire is passed conduit 1, under the guiding of conduit 1, the linear silicon sebific duct is implanted lacrimal passage; Can in lacrimal surgery, put pipe easily and carry out Anastomosis of Broken Lacrimal Canaliculus, thereby reduce in the operation, improve the success rate of doctor's operation patient's damage.

Soft lacrimal passage described in the utility model is put the pipe guidance system, it is characterized in that: the diameter that soft lacrimal passage is put conduit in the pipe guidance system is a bit larger tham the linear silicon sebific duct, less than lacrimal ductule, helps the implantation of linear silicon sebific duct; The conduit material is soft, has the damage of minimizing lacrimal passage, prevents via forming, easily enter the advantage in the lachrymal sac; Effectively avoid the total inside pipe wall mucosa injury of lacrimal ductule/tear, operation safety is carried out, easy and simple to handle.

More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.

Claims

1. soft lacrimal passage is put the pipe guidance system, and it comprises: conduit is formed with stainless pin two parts of band pintle, it is characterized in that: the conduit material soft and above be printed on scale, scale spacing is 1cm, internal diameter is 1mm, head end is blunt round cecum band side opening; The pintle of the blunt circle of stainless pin head end, cavity and upper end band flushing interface.
