Description

Limiting stopper of forward lacrimal drainage tube

Technical Field

The utility model relates to a drainage tube stopper field, especially a stopper of cisoid lacrimal passage drainage tube.

Background

With the advent of the age of minimally invasive surgery, various endoscopic surgical techniques are continuously developed and perfected, and the success rate of laser surgery through lacrimal passages is continuously improved. The consequent lacrimal drainage tube ensures that the postoperative fistulization channel keeps unobstructed effective temporary auxiliary support, but clinically only three continuous nodules are made by the drainage tube itself for limiting, and the drainage tube cannot be effectively limited in a fistulization area. Because the drainage tube is made of silica gel, the drainage tube is easy to deform, and often postoperative nodules are accidentally pulled into a lacrimal sac to cause operation failure, or a patient accidentally pulls out the drainage tube to cause pipeline breakage, residue and the like, and the residual end needs to be taken out again through operation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's not enough, provide a stopper of cisoid lacrimal passage drainage tube, spacing effectively in fistulization region with the drainage tube, avoid the nodule to be leaded to the operation failure in unexpected tractive to the dacryocyst, perhaps the patient is unexpected to extract the drainage tube and lead to the pipeline fracture, remain the circumstances such as, need the operation once more and take out the stub.

The purpose of the utility model is realized through the following technical scheme:

a limiting block of a forward lacrimal passage drainage tube comprises a limiting block, wherein the transverse diameter of the upper end of the limiting block is larger than 0.5 cm, a through hole is formed in the limiting block along the top-down direction, the forward lacrimal passage drainage tube can penetrate through the through hole, and the upper end surface of the limiting block is an inclined surface.

Further, the transverse diameter of the lower end of the limiting block is larger than 0.5 cm, and the lower end surface of the limiting block is an inclined surface.

Furthermore, the top of the limiting block is an arc surface.

Furthermore, the top and the bottom of the limiting block are both cambered surfaces.

Furthermore, the transverse diameters of the upper end and the lower end of the limiting block are not equal.

Furthermore, the transverse diameters of the upper end and the lower end of the limiting block are both 0.5-2.5 cm, and the transverse diameter of the through hole is 0.3-1.5 cm.

Furthermore, the transverse diameter of the upper end of the limiting block is 2.1 cm, and the transverse diameter of the through hole is 1.1 cm.

Further, the transverse diameter of the lower end of the limiting block is 2.1 cm.

As another design, the transverse diameter of the lower end of the limiting block is 1.5 cm.

Furthermore, the longitudinal diameter of the limiting block is between 2 and 4.5 centimeters.

The utility model has the advantages that:

the upper end of the limiting block is an inclined plane, when the drainage tube is pulled accidentally, the top of the limiting block is contacted with the anastomosis area and then automatically rotates under the action of the lever principle, so that the limiting block is clamped at the nasal cavity end of the anastomosis area to exert the limiting function.

Therefore, the limiting effect can be achieved no matter the conventional double-strand drainage tube passes through the through hole or only a single-strand drainage tube passes through the through hole due to the limitation of operation technology. Therefore, the limiting difficulty of the forward lacrimal duct drainage tube can be solved, the drainage tube is effectively limited in a fistulization area, the condition that the nodule is accidentally pulled into a lacrimal sac to cause operation failure, or a patient accidentally pulls out the drainage tube to cause pipeline breakage, residue and the like is avoided, the stump needs to be taken out for the secondary operation, and the damage to the patient and the secondary operation caused by the accidental dislocation and incarceration are also avoided.

The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.

The first embodiment is as follows:

as shown in fig. 1 to 5, the stopper of the antegrade lacrimal passage drainage tube comprises a stopper 1, wherein the transverse diameter of the upper end of the stopper 1 is larger than 0.5 cm, a through hole 11 is arranged on the stopper 1 along the direction from top to bottom, the through hole 11 is used for the antegrade lacrimal passage drainage tube 2 to pass through, and the upper end surface 12 of the stopper 1 is an inclined surface.

The top and the bottom of the limiting block 1 are both cambered surfaces. Therefore, the patient can be prevented from being scratched by the top tip of the limiting block 1.

The using method comprises the following steps:

when the drainage tube 2 needs to be arranged on the main body part of the clinical lacrimal passage operation, after the conventional drainage tube implantation operation is carried out, the two drainage tubes 2 are led out from the nasal cavity, at the moment, the two drainage tubes 2 penetrate through the through hole 11, if the two drainage tubes 2 are difficult to penetrate, one drainage tube 2 can penetrate through the through hole 11, the other drainage tube does not penetrate through the through hole 11, after the proper tightness is adjusted, the limiting block 1 is pushed to the position of the anastomotic stoma, the two drainage tubes 2 are continuously knotted for more than three times, and the redundant drainage tubes are cut off at a distance of more than 5mm from the knots.

The upper end face 12 of the limiting block 1 is an inclined plane, when the drainage tube 2 is pulled accidentally, the top of the limiting block 1 is contacted with the anastomotic region and then automatically rotates along the direction shown in figure 5 under the action of the lever principle, so that the limiting block 1 is clamped at the nasal cavity end of the anastomotic region to exert the limiting function.

Therefore, the limiting effect can be achieved whether the conventional double-strand drainage tube 2 passes through the through hole 11 or only the single-strand drainage tube 2 passes through the through hole 11 due to the limitation of operation technology.
