The present embodiment provides a kind of canaliculitis scalers, please with reference to Fig. 1 to Fig. 5 in Figure of description.Fig. 1 is
Structural schematic diagram when canaliculitis scaler provided by the utility model is not operating；Fig. 2 is the enlarged drawing of a-quadrant in Fig. 1；Figure
3 be the enlarged drawing of B area in Fig. 1；Fig. 4 is the cross-sectional view in the face A-A along Fig. 1；Fig. 5 is canaliculitis provided by the utility model
Structural schematic diagram after scaler movement.
As depicted in figs. 1 and 2, which includes floating rule 1, shell 2 and executing agency 3；Shell 2 includes set
Pipe 21 and handle 22；Executing agency 3 is installed on inside handle 22；Floating rule 1 is installed in casing 21, and tail end protrudes into the interior of handle 22
It is connect after chamber with executing agency 3, head end is provided with blade, and floating rule 1 can be along the length of casing 21 under the driving of executing agency 3
It is mobile to spend direction.
When being performed the operation using the canaliculitis scaler, casing 21 is protruded into lacrimal by hand-held handle 22, and operation executes
Mechanism 3, floating rule 1 move forward, and the head end of floating rule 1 stretches out casing 21, then using the blade of head end to the polyp in lacrimal
It is struck off with calculus.Executing agency 3 is operated after the completion of striking off, and floating rule 1 is moved backward, the head end of floating rule 1 returns to casing 21
It is interior, then take out casing 21.
When protruding into and taking out lacrimal, the head end of floating rule 1 is located in casing 21 the canaliculitis scaler, prevents blade
Lacrimal wall is caused to damage.The head end of the floating rule 1 has blade, can once be struck off using blade to polyp and calculus dry
Only, the injury repeatedly struck off or wiped out to lacrimal is avoided.
The floating rule 1 of the canaliculitis scaler described in detail below.
As shown in Figure 1, floating rule 1 includes shaft 11 and scrapes first 12；The both ends of shaft 11 are connected to executing agency 3 and scrape
First 12；First 12 are scraped as spoon type, and edge is blade.
When being performed the operation using the canaliculitis scaler, executing agency 3 is operated, executing agency 3 drives floating rule 1 to Forward
It is dynamic, it scrapes first 12 and stretches out casing 21；Using scrape first 12 blade in lacrimal polyp and calculus strike off.Due to scraping first 12
It is spoon-shaped structure, polyp and calculus can be contained in spoon-shaped structure.Executing agency 3 is operated again, floating rule 1 moves backward,
It scrapes first 12 to retract in casing 21, then takes out casing 21.
The shell 2 of the canaliculitis scaler described in detail below.
As shown in Figure 1 and Figure 5, shell 2 includes casing 21 and handle 22；Casing 21 includes pipe shaft 211 and tube head 212；Pipe

Pressure hole 221 is distributed across multiple through-holes on 22 rear end face of handle.
When doctor, which operates executing agency 3, moves forward floating rule 1, the air pressure inside shell 2 reduces, and external air is logical
It crosses balancing orifice 221 to be externally entering inside shell 2, the inside and outside air pressure of balance shell 2 avoids 2 air pressure inside of shell from dropping
The low movement for influencing floating rule 1.When doctor, which operates executing agency 3, moves backward floating rule 1, the air pressure inside shell 2 increases, empty
Gas flows out to outside by balancing orifice 221 inside shell 2, and the inside and outside air pressure of balance shell 2 avoids inside shell 2
Air pressure increases the movement for influencing floating rule 1.
The executing agency 3 of the canaliculitis scaler described in detail below.
As shown in Figure 1 and Figure 5, executing agency 3 includes Power Component 31 and elastic parts 32；Power Component 31 and floating rule 1
Tail end connection, for driving floating rule 1 mobile；The both ends of elastic parts 32 are connected to the inner wall of shaft 11 and handle 22,
For driving 1 return of floating rule.
When being performed the operation using the canaliculitis scaler, casing 21 is protruded into lacrimal, operates Power Component 31, is moved
Power component 31 drives floating rule 1, and floating rule 1 moves forward, and scrapes first 12 and stretches out casing 21.Polyp and knot are struck off using the blade for scraping first 12
After the completion of stone, polyp and calculus are struck off, it is contained in the spoon-shaped structure for scraping first 12.Stop operation Power Component 31, floating rule 1
It moves backward, is returned in casing 21 under the action of elastic parts 32.Finally, taking out the casing 21 in lacrimal.
In the optinal plan of the present embodiment, more preferably,
As depicted in figs. 1 and 2, Power Component 31 includes hydraulic cylinder 311, fluid reservoir 312 and moccasin 313；Moccasin 313 is installed
In handle 22, under external force, can deform to the inside of handle 22；Fluid reservoir 312 is made of soft materials, installation
In the inside of handle 22, internal reservoir has liquid medium, and the inside face contact of lateral surface and moccasin 313；Hydraulic cylinder 311 is installed
Inside handle 22, it is connected to positioned at the front of fluid reservoir 312, and by pipeline with fluid reservoir 312；The tail end of floating rule 1 protrudes into liquid
Cylinder pressure 311 is connect with the hydraulic plate 3111 of hydraulic cylinder 311.
Moccasin 313 can be the soft materials such as rubber, silica gel and be made, and fluid reservoir 312 can be by materials such as flexible plastic, rubber
It is made.
When operating Power Component 31, make to press with finger the moccasin 313 on handle 22, moccasin 313 is to sending out inside handle 22
Change shape, also deforms with the fluid reservoir 312 of the inside face contact of moccasin 313, the liquid medium in fluid reservoir 312 is squeezed
Out, liquid medium flows into hydraulic cylinder 311, and the hydraulic plate 3111 of hydraulic cylinder 311 moves forward, hydraulic plate 3111 drive floating rule 1 to
Preceding movement, and then make to scrape first 12 stretching casing 21.
In the optinal plan of the present embodiment, more preferably,
As shown in Figure 1 and Figure 5, elastic parts 32 includes spring 321, first baffle 322 and second baffle 323；First gear
Plate 322 is set to the inner wall of shell 2, and second baffle 323 is set to floating rule 1；Spring 321 is set in floating rule 1, and both ends connect respectively
It is connected to first baffle 322 and second baffle 323.
After floating rule 1 moves forward, scrapes first 12 stretching casing 21, the spring 321 of elastic parts 32 is compressed.Work as lacrimal
In polyp and calculus be scraped clean in the spoon-shaped structure for being contained in and scrape first 12 after, unclamp moccasin 313, floating rule 1 is in spring 321
Under the action of move backward, the rear end of floating rule 1 drives hydraulic plate 3111 to move backward, and the liquid medium in hydraulic cylinder 311 is squeezed
Out, liquid medium flows back to fluid reservoir 312.
Above-mentioned liquid medium is preferably pure water, can also be medicinal alcohol etc..
The present embodiment further includes strainer 4, the strainer 4 of the canaliculitis scaler described in detail below.
Strainer 4 is installed on inside shell 2, and between balancing orifice 221 and fluid reservoir 312.
In the optinal plan of the present embodiment, more preferably,
As shown in figure 4, shaft 11 and pipe shaft 211 are partial circle shape.
Due to the diameter very little of lacrimal, shaft 11 and pipe shaft 211 can make to cover using the cross sectional shape of partial circle shape
Pipe 21 moves in the gap of muti-piece calculus and polyp, avoid by lacrimal calculus or polyp push the depths of lacrimal to.
In the optinal plan of the present embodiment, more preferably,
Non-slip texture is arranged in the lateral surface of handle 22.
Operation due to using the canaliculitis scaler requires doctor and accurately controls the canaliculitis scaler, and tear is small
Any skidding is all very dangerous pipe inflammation scaler in the hand, can place this in the lateral surface setting non-slip texture of handle 22
Canaliculitis scaler skids in the hand, and then avoids causing patient unnecessary injury.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
