Abstract
The utility model discloses a lacrimal passage drainage support, and relates to a medical instrument, in particular to a structural improvement of the lacrimal passage drainage support. The lacrimal passage drainage support comprises a drainage tube (1). A silica gel cap (2) is arranged at one end of the drainage tube (1) and is a tube body, wherein one end of the tube body is closed, and the longitudinal section of the tube body is in a U shape; the drainage tube (1) is arranged at the closed end of the silica gel cap (2) and communicated with the silica gel cap (2), and a ligature (3) for knotting the free end of the drainage tube (1) is connected to the inner wall of the closed end of the silica gel cap (2). The lacrimal passage drainage support has the advantages of being reasonable in design, simple in structure, low in manufacturing cost, convenient to operate and good in treatment effect.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to the architecture advances of probing of lacrimal passage support.
Background technology
Lacrimal ductule, nasolacrimal duct and punctual stenosis, obstruction, and in the therapeutic process of the disease such as dacryocystisis, conventional lacrimal passage drainage tubes is because pipe external drainage is inadequate, cause tube drawing after lacrimal passage easily closed again; After dacryocystorhinostomy, anastomotic stoma, because rheuminess thing or blood clot factor can cause anastomotic stricture or closed again, all can cause operative failure, makes operation be difficult to produce a desired effect.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of probing of lacrimal passage support that improves structure is provided, for after dacryocystisis, stricture of lacrimal passage and dacryocystorhinostomy, play support and the outer flushable and pipe external drainage to a certain extent of pipe to prevent dacryocystorhinostomy anastomotic stenosis after surgery or locking, consolidate and strengthen surgical effect after dacryocystisis, stricture of lacrimal passage and dacryocystorhinostomy.
Technical solution of the present utility model is: it comprises drainage tube, one end of described drainage tube is provided with silicon rubber cup, silicon rubber cup is the body that the longitudinal section of one end sealing is " U " shape, drainage tube is located at the blind end of silicon rubber cup and is communicated with silicon rubber cup, and silicon rubber cup is connected with for the ligature with the knotting of drainage tube free end in the inwall of blind end.
Technique effect of the present utility model is: it have advantages of reasonable in design, simple in structure, cost is low, handled easily and therapeutic effect good.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is the cross section structure schematic diagram of this utility model silicon rubber cup.
The specific embodiment
As illustrated in fig. 1 and 2, it comprises drainage tube 1, one end of described drainage tube 1 is provided with silicon rubber cup 2, the longitudinal section that silicon rubber cup 2 seals for one end is the body of " U " shape, drainage tube 1 is located at the blind end of silicon rubber cup 2 and is communicated with silicon rubber cup 2, and silicon rubber cup 2 is connected with for the ligature 3 with drainage tube 1 free end knotting in the inwall of blind end.
The wall of described silicon rubber cup 2 is provided with some through holes 4.The wall of described silicon rubber cup 2 is provided with some drainage troughs that concave 5.The blind end of described silicon rubber cup 2 is provided with suspension part 6 in the inwall of itself and drainage tube 1 below, junction, and described ligature 3 is connected on this suspension part 6.
When this utility model can be used for after the simple catheter drainage of dacryocystisis, dacryocystorhinostomy that (silicon rubber cup length adjustment is 1 centimetre) and dacryocystisis merge stricture of lacrimal passage.Using method is, lacrimal point in expansion inserts band seal wire probe (enter visual area in dacryocystorhinostomy, dacryocystisis enters inferior nasal meatus), derives seal wire, drainage silicon rubber tube free-end is inserted in thread eye, and pull back probe and seal wire, silica gel tube goes out from upper lacrimal point; The lower lacrimal point of expansion, insert probe, No. 4 lines are pulled out to lower lacrimal point from nasal cavity or identical visual area, again silica gel tube is drawn in to nasal cavity or visual area with line, silicon rubber cup is placed in nose lacrimal passage, or is placed in lachrymal sac anastomotic stoma place, the latter must cut silicon rubber cup to 1 centimetre of left and right, ligature and drainage silicon rubber tube knotting are placed on to nasal cavity, within 3-6 month, cut off medial canthal silica gel tube, from nasal cavity, pull out.
This utility model rinses weekly 1 time, and continuous 3 times, rear every first quarter moon rinses 2 times, because silicon rubber cup is provided with through hole and drainage trough structure, when rinsing, can rinse out in time when injected organism tissue secretions, prevent adhesion, thereby guaranteed success rate of operation, improved surgical effect.
