Description
Technical field
This utility model relates to a kind of punctum dilator with illuminator, for ophthalmologic operation, belongs to technical field of medical instruments.
Background technology
The margo palpebrae of the nearly endocanthion of eyes of people respectively has little dots structure, i.e. a puncta up and down, is the initial position of lacrimal passage (tear discharge system).When puncta has inaccessible or narrow, need the expansion of row lacrimal point, irrigation of lacrimal passage.First use the head end of punctum dilator to aim at puncta during operation, insert and expand puncta, and the precondition of this operation is good illumination.
The punctum dilator used clinically is at present without light source, if available light is not good enough or when not having a good illumination, easily cause operation failure, even injure eyelid, eyeball, increase patient suffering.
Summary of the invention
The purpose of this utility model is to provide a kind of punctum dilator with light source.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of punctum dilator with illuminator, comprise the spy cleansing pin of hollow, the lower end visiting cleansing pin is lacrimal point upstream end, it is characterized in that: be provided with dismountable light source in the upper end visiting cleansing pin.
Preferably, the upper end of described spy cleansing pin is threaded with described light source.
Preferably, described light source comprises housing, is provided with the LED of irradiating straight down in housing, and LED forms loop via the switch on housing and the battery in housing.
Preferably, be provided with on the housing and climb.
A kind of punctum dilator with illuminator that this utility model provides, for lacrimal point expansion, irrigation of lacrimal passage, make doctor be expert at lacrimal point expansion time see more clear, make simple operation, effectively, safety.
Accompanying drawing explanation
The schematic diagram of a kind of punctum dilator with illuminator that Fig. 1 provides for this utility model.
Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1, this utility model provides a kind of punctum dilator with illuminator, comprises and visits cleansing pin 1 and light source 2.Visiting cleansing pin 1 is hollow pipe, can light shine the lower end visiting cleansing pin 1.The lower end visiting cleansing pin 1 is lacrimal point upstream end 9, and in the present embodiment, lacrimal point upstream end 9 is round end, is more convenient for entering lacrimal point.The upper end visiting cleansing pin 1 is provided with external screw thread 8, can be connected, be integrated with light source 2 one-tenth with the female thread 7 of light source 2 lower end.Visit cleansing pin 1 to be separated with light source 2, the sterilization after easy to use.Light source 2 comprises housing, is provided with the switch 3, battery 4, the LED 5 that connect into loop in enclosure interior.There is one to climb 6 in the outside of housing, be easy to carry.
During use, be connected with light source 2 with external screw thread 8 by female thread 7 by the spy cleansing pin 1 after sterilization, press the switch 3 on light source 2 top, LED 5 is bright, and light forms luminous point by visiting cleansing pin 1 at round end place, lower end, and convenient cleansing pin 1 of visiting enters lacrimal point.
