Abstract
The utility model discloses a lacrimal implantation tube, and consists of a drainage-tube with one blunt end made by comparative hard spinal dura mater analgesia tube, and an implantation tube. The joint between the two tubes is integrated by strong bond. A metal probe with handle is inserted from the open end of the lacrimal passage implantation tube to the blunt end. The operation by the implantation tube can reduce the labor intensity of the operators, and shorten the operating time, reduce the pain of patient, reduce the infection and improve the success rate. The utility model is suitable for the operation curing for patients with blocking lacrimal passage.
Description
This utility model relates to a kind of Lacrimal implantation tube, belongs to ophthalmology lacrimal surgery apparatus, uses when being particularly suitable for the treatment of obstructed lacrimal passage corrective surgery.
Mainly take hanging wire, implant logical again art of justice pipe, nasal cavity lachrymal sac anastomosis, laser and the logical again art of high-frequency electrical for obstructed lacrimal passage disease patient clinically at present.The hanging wire art is seldom used owing to weak curative effect.Logical again art of laser and the logical again art of high-frequency electrical are subjected to the economic condition restriction to be not easy to promote the use of at basic hospital, and must implant lacrimal passage justice pipe simultaneously for some patient owing to apparatus expensive.The lacrimal passage justice pipe that uses in the clinical operation is now made by water white silicone rubber.Its quality softness, tissue intersolubility is good, but can not directly implant lacrimal passage, must drive in the wrong direction from nasal cavity with metal probe and peridural anesthesia pipe for importing.And need on-the-spot the stitching between justice pipe and the guiding tube, and complex operation, operating time is long, easy infection, success rate of operation is low.It is attractive in appearance that nasal cavity lachrymal sac anastomosis leaves facial cicatrix influence, is difficult to patient and accepts.
Task of the present utility model is a kind of novel Lacrimal implantation tube of design, and justice pipe and guiding tube are linked into an integrated entity, and alleviates doctor's labor intensity, shortens operating time, improves the surgical healing rate.
Task of the present utility model is achieved in that a kind of novel Lacrimal implantation tube of design, form by guiding tube, implantation justice pipe and metal probe, front end is that the guiding tube of the blunt cecum of circle and the joint between the adopted pipe of implantation are the strong adhesive bonding connection, and metal probe is inserted into the blunt cecum of circle of guiding tube by the opening of Lacrimal implantation tube.The Lacrimal implantation tube design length is 200mm, and wherein the leading portion guiding tube respectively is 100mm with the length of implanting adopted pipe, and the external diameter of pipe is 0.8-1.0mm, thickness of pipe wall 0.1mm.
Advantage of the present utility model, be after novel Lacrimal implantation tube is used for operation, guiding tube need not be sewed up with the adopted pipe of implantation and be connected, can alleviate the labor intensity of operative doctor, shorten operating time 1/3rd, reduce patient's misery, reduce infection chance, save patient's expense, improved success rate of operation.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
Fig. 1 is the guiding tube sketch map of Lacrimal implantation tube
Fig. 2 is the implantation justice pipe sketch map of Lacrimal implantation tube
Fig. 3 is a Lacrimal implantation tube pipe structure sketch map
Fig. 4 is the Lacrimal implantation tube structural representation
With reference to Fig. 1, Fig. 2, Fig. 3, illustrate that the Lacrimal implantation tube body is made up of guiding tube (1), implant (2).Guiding tube is that the harder spinal meninges of quality is anaesthetized rubber catheter outward and made, and front end is the circle obtuse cecum, is beneficial to insert lacrimal passage, and the rear end is the opening shape.Implant justice pipe (be lacrimal passage be detained pipe) and make the tubulose of both ends open, help being detained for a long time in tissue and be convenient to fix for quality softness, silicone rubber that tissue intersolubility is good.Be integral with strong adhesive (as C3H6O) bonding connection at guiding tube (1) and the joint (3) of implanting justice pipe (2).
Fig. 4 is by guiding tube (1), implants the configuration state that justice is managed the Lacrimal implantation tube of (2), metal probe (4) formation.Metal probe is that stainless steel silk is made, and end is provided with handle (5), and is convenient manipulation.Probe is inserted into the blunt cecum of circle from the opening of Lacrimal implantation tube body.
The Lacrimal implantation tube product adopts double casing, is placed in the ethylene oxide sterilizer and sterilizes, and opens during operation and can use.
Operation principle: open the Lacrimal implantation tube after the sterilization during operation, the guiding tube cecum is inserted lacrimal point down, rely on the hardness of guiding tube and stainless steel silk, pass lacrimal ductule, lachrymal sac and nasolacrimal duct successively, pass nasal cavity from inferior nasal meatus, light drawing conduit makes the pipe of being detained arrive outside the nasal cavity by lacrimal passage downwards, following lacrimal point stays the pipe 5mm that is detained outward, takes out the stainless steel silk probe.Microscopically will be detained pipe with the 8-0 silk thread on, sew up a pin, be fixed in 2mm place skin surface under the lower eyelid eyelashes root.Be detained outside nasal cavity is cut lacrimal passage and manage and guiding tube, prune the pipe upper end of being detained and make it to be lower than lacrimal point 1mm down, operation is finished.
Embodiment: two parts before and after novel Lacrimal implantation tube is designed to, total length 200mm, guiding tube (1) 100mm implants justice pipe (2) 100mm, external diameter of pipe 0.8-1.0mm, thickness of pipe wall 0.1mm.The long 220mm of stainless steel silk probe, diameter 0.38mm, the long 15mm of handle.
Claims (2)
1, a kind of Lacrimal implantation tube is made up of guiding tube, implantation justice pipe and metal probe, the joint (3) that it is characterized in that guiding tube (1) and implant between the justice pipe (2) is the strong adhesive bonding connection, and metal probe (4) is inserted into the blunt cecum of circle by the opening of Lacrimal implantation tube.
2, Lacrimal implantation tube according to claim 1 is characterized in that the Lacrimal implantation tube design length is 200mm, and wherein leading portion guiding tube and the back segment length of implanting adopted pipe respectively is 100mm, and the external diameter of pipe is 0.8-1.0mm, thickness of pipe wall 0.1mm.
