Abstract
This utility model relates to field of ophthalmological medical equipment, in particular to a kind of Lacrimal passage tube probe dredged for nasolacrimal duct in art, comprise elongated tubulose draw point, described draw point one end is communicated with the needle handle of hollow, the described draw point other end is smooth blind end, draw point wall near described draw point blind end is provided with skew back otch, be provided with in described draw point a two ends closed loop bifilar and the memory alloy wire that can freely up and down pull, one of them blind end of described memory alloy wire is provided with hook-type and connects end, described hook-type connects end and penetrates draw point from needle handle and pass draw point pipe from the skew back otch of lower end.When adopting Lacrimal passage tube probe of the present utility model to carry out nasolacrimal duct bypass operation, can operation process be simplified, shorten the Lacrimal passage tube probe of operating time, and the success rate of operation can be improved, reduce patient ailing.
Description
Technical field
This utility model relates to field of ophthalmological medical equipment, particularly puts the Lacrimal passage tube probe of pipe in a kind of tear stains tube placing operation for placing silica-gel lacrimal.
Background technology
Tear flow into nasal cavity from eyes through upper and lower lacrimal ductule, tear house steward, lachrymal sac, nasolacrimal duct.If this passage blocks because of pathological changes, excessive tear will be caused, a series of pathological changes such as dacryocystisis.Need to carry out operation dredging treatment in time.The main dacryocystorhinostomy that adopts combines tear stains tube placing operation or lacrimal passage drainage tubes implantation etc. at present.Need along the reverse silica gel tube of inserting for supporting lacrimal passage of nasolacrimal duct in operation, this Lacrimal passage tube end has a traction end for drawing, hollow probe is adopted to visit catharsis puncta, lower lacrimal canaliculi, tear house steward, lachrymal sac, nasolacrimal duct successively in operation, in nasolacrimal duct lower end, Lacrimal passage tube is upwards drawn to lower puncta by draught line, complete and put pipe operation.There are the following problems for Lacrimal passage tube in this operation and probe: 1, this traction end end often easily rubs patient eyeball, and causes a series of discomfort of patient or postoperative complication.2, superior canaliculus obstruction can not be treated, puncta is inaccessible.
Utility model content
This utility model, for the above-mentioned problems in the prior art, provides a kind of and can reduce the Lacrimal passage tube probe that corrective surgery does not accommodate complication, effectively treatment treatment associating superior canaliculus obstruction, puncta obturation, and improves the curative effect of operation.
The purpose of this utility model realizes like this, a kind of Lacrimal passage tube probe, comprise elongated tubulose draw point, described draw point one end is communicated with the needle handle of hollow, the described draw point other end is smooth blind end, it is characterized in that, draw point wall near described draw point blind end is provided with skew back otch, be provided with in described draw point a two ends closed loop bifilar and the memory alloy wire that can freely up and down pull, the hook-type that the straight shape that described memory alloy wire comprises top connects end and bottom connects end, described hook-type connects end and penetrates draw point from needle handle and pass draw point from the skew back otch of lower end.
Lacrimal passage tube probe of the present utility model, by in draw point can free pulling force and the bifilar memory alloy wire of closed at both ends, when carrying out Lacrimal passage tube operation, two blind ends of memory alloy wire freely can pull the draught line of traction Lacrimal passage tube respectively from upper and lower both direction, the traction of positive and negative both direction can be realized, when spy catharsis lacrimal ductule, lachrymal sac, during nasolacrimal duct, memory alloy wire is stretched out to nasal cavity by draw point, and by memory alloy wire hook-type connect end (nose) carry silica gel tube traction end from nasolacrimal duct lower end reverse introducing nasolacrimal duct, lachrymal sac, lower lacrimal canaliculi, go out lower lacrimal canaliculi.When visiting logical superior canaliculus, lachrymal sac, nasolacrimal duct with draw point again, memory alloy wire is stretched out to nasal cavity by eye end, connects end (eye end) carry that the traction end of elongated silica gel tube to be inserted superior canaliculus by silica gel tube draught line, lachrymal sac, nasolacrimal duct to nasal cavity complete Lacrimal passage tube and perform the operation by the straight shape of memory alloy wire.Therefore, adopt Lacrimal passage tube probe of the present utility model can reduce corrective surgery and do not accommodate complication, the curative effect that effectively treatment treatment associating superior canaliculus blocks, puncta obliterans also improves operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of Lacrimal passage tube probe of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1 at B place.
Wherein, 1 draw point, 1A skew back otch, 2 needle handles, 3 memory alloy wires, 3A hook-type connects the straight shape of end .3B and connects end.
Detailed description of the invention
Be Lacrimal passage tube probe of the present utility model as depicted in figs. 1 and 2, comprise elongated tubulose draw point 1, draw point 1 one end is communicated with the needle handle 2 of hollow, draw point 1 other end is smooth blind end, draw point wall near draw point 1 blind end is provided with skew back otch 1A, be provided with in draw point 1 a two ends closed loop bifilar and the memory alloy wire 3 that can freely up and down pull, the hook-type that the straight shape that memory alloy wire 3 comprises top connects end 3B (both eye end) and bottom connects holds 3A (both nose), hook-type connects end 3A and penetrates draw point 1 from needle handle 2 and pass draw point 1 from the skew back otch 1A of lower end, pass from skew back otch 1A smoothly for ease of memory alloy wire 3 in operation, the draw point 1 on the downside of skew back otch 1A be solid, and is provided with the hook-type being convenient to memory alloy wire 3 and connects and hold 3A to pass the skew back face of draw point from skew back otch 1A, as shown in Figure 2.
When adopting Lacrimal passage tube probe of the present utility model to carry out Lacrimal passage tube operation, by in draw point 1 can free pulling force and the bifilar memory alloy wire 3 of closed at both ends, when carrying out Lacrimal passage tube operation, two blind ends of memory alloy wire 3 can freely pull from upper and lower both direction the draught line be looped around memory alloy wire 3 respectively, traction Lacrimal passage tube, the traction of positive and negative both direction can be realized, when spy catharsis lacrimal ductule, lachrymal sac, during nasolacrimal duct, memory alloy wire is stretched out to nasal cavity by draw point, and by memory alloy wire hook-type connect end 3A carry silica gel tube traction end from nasolacrimal duct lower end reverse introducing nasolacrimal duct, lachrymal sac, lower lacrimal canaliculi, go out lower lacrimal canaliculi.When visiting logical superior canaliculus, lachrymal sac, nasolacrimal duct with draw point 1 again, memory alloy wire 3 connects end 3B by straight shape and stretches out to nasal cavity, connects end 3B carry that the traction end of elongated silica gel tube to be inserted superior canaliculus by silica gel tube draught line, lachrymal sac, nasolacrimal duct to nasal cavity complete Lacrimal passage tube operation by the straight shape of memory alloy wire.Therefore, adopt Lacrimal passage tube probe of the present utility model can reduce corrective surgery and do not accommodate complication, the curative effect that effectively treatment treatment associating superior canaliculus blocks, puncta obliterans also improves operation.
