Description
Technical field
It the utility model is related to a kind of medicine equipment, and in particular to a kind of lachrymal gland retractor.
Background technology
Lachrymal gland retractor is also known as lachrymal gland drag hook, to retract lacrimal tissue, is easy to detect and operates, can be divided into hand-held drag hook
With the class of self-retractor two.The lachrymal gland retractor of prior art in use there is deficiency, such as retract pawl quantity it is fewer,
Sometimes what can not be consolidated retract, and is retracted using process slower, it is impossible to the visual field is exposed well, the exposed visual field is smaller sometimes,
The musculature of gathering is few, and haemostatic effect is poor, the folding less stable of drawing arm, influences operation technique, and drawing arm
Folding degree of regulation it is not high, undoubtedly add the difficulty of operation.
Utility model content
The utility model is in order to solve weak point of the prior art, there is provided it is a kind of it is simple in construction, operational stability is high,
The lachrymal gland retractor of folding can subtly be adjusted.
In order to solve the above technical problems, the utility model adopts the following technical scheme that:Lachrymal gland retractor, including handle and two
Root drawing arm, by the first hinge in the upper end of handle, two drawing arms are symmetrical to be set for the lower ends of two drawing arms
Put, some traction pawls are equipped with the outside of the upper end of two drawing arms, handle, which is provided with, is used for two drawing arm foldings of driving
Drive mechanism;Handle is provided with anti-skid structure;
Drive mechanism includes drive rod, gear, left connecting rod and right connecting rod, and open top is offered in the axial direction in handle
Guide groove, the leading flank of handle offers the mounting hole connected with guide groove, rack is provided with along its length on front side of drive rod,
The bottom of drive rod is vertically plugged in guide groove, and pinion rotation is connected in mounting hole and the center line edge of gear
Left and right horizontal direction is set, and the leading flank of mounting hole, wheel and rack engaged transmission, the lower end of left connecting rod are protruded from front side of gear
With the lower end of right connecting rod by the second hinge in the upper end of drive rod, the upper end of left connecting rod is hinged on the drawing arm in left side
On, the upper end of right connecting rod is hinged on the drawing arm on right side.
Anti-skid structure includes vertically being provided with four along the circumferentially disposed anti-slip tank of handle, anti-slip tank, anti-slip tank table
Face is provided with anti-slip veins.
Using above-mentioned technical proposal, when the utility model is specifically used, handle is grasped, then thumb promotes tooth
Wheel, pinion rotation band carry-over bar move up, and so as to which drive rod follows rack to be moved up along guide groove, the upper end of drive rod pushes away
Dynamic left connecting rod and right connecting rod, left connecting rod and right connecting rod push out two drawing arms, and the upper end of two drawing arms is opened, so as to lead
Pawl is opened to open lachrymal gland traction;Because the utility model is using the closure of rack pinion structure completion drawing arm, all degrees of regulation
Height, and stability is poor;Four anti-slip tanks of design meet the shape of people's holding, and more rationally, anti-skidding rooved face is provided with anti-skidding
Line, anti-slip veins can prevent people from being come off when holding, improve the security of operation;
In summary, the utility model is reasonable in design, easy to operate, can subtly adjust folding, so as to safety
Completion lachrymal gland traction operation, it is practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, lachrymal gland retractor of the present utility model, including handle 1 and two drawing arms 2, two drawing arms 2
Lower end is hinged on the upper end of handle 1 by the first bearing pin 3, and two drawing arms 2 are symmetrical set, two drawing arms 2 it is upper
Some traction pawls 4 are equipped with the outside of end, handle 1 is provided with the drive mechanism for being used for driving two foldings of drawing arm 2;Handle 1
It is provided with anti-skid structure;
Drive mechanism includes drive rod 5, gear 6, left connecting rod 7 and right connecting rod 8, and top is offered in the axial direction in handle 1
The open guide groove in portion, the leading flank of handle 1 offer the mounting hole 9 connected with guide groove, and the front side of drive rod 5 is along its length
Provided with rack, the bottom of drive rod 5 is vertically plugged in guide groove, and gear 6 is rotatably connected in mounting hole 9 and tooth
The center line of wheel 6 is set along left and right horizontal direction, and the front side of gear 6 protrudes from the leading flank of mounting hole 9, and gear 6 engages with rack
Transmission, the lower end of left connecting rod 7 and the lower end of right connecting rod 8 are hinged on the upper end of drive rod 5, left connecting rod 7 by the second bearing pin 10
Upper end be hinged on the drawing arm 2 in left side, the upper end of right connecting rod 8 is hinged on the drawing arm 2 on right side.
Anti-skid structure includes anti-skidding vertically provided with four along the circumferentially disposed anti-slip tank 11 of handle 1, anti-slip tank 11
The surface of groove 11 is provided with anti-slip veins 12.
When the utility model is specifically used, handle 1 is grasped, then thumb promotes gear 6, and gear 6, which rotates, to be driven
Rack moves up, and so as to which drive rod 5 follows rack to be moved up along guide groove, the upper end of drive rod 5 promotes left connecting rod 7 and the right side
Connecting rod 8, left connecting rod 7 and right connecting rod 8 push out two drawing arms 2, and the upper end of two drawing arms 2 is opened, will so as to retract pawl 4
Lachrymal gland traction is opened.
The present embodiment not makees any formal limitation, every foundation to shape of the present utility model, material, structure etc.
Any simple modification, equivalent change and modification that the technical essence of the utility model is made to above example, belongs to this reality
With the protection domain of new technique scheme.
