Description
Technical field
This utility model relates to a kind of lacrimal surgery device, belongs to medical apparatus technical field.
Background technology
Traditional lacrimal surgery is dacryocystorhinostomy, the operation lacrimal passage structure that changes its course, and success rate of operation is high but facially damage scar trace, and the structural change of nose lacrimal passage, and postoperative breathing has cavity sense sometimes.Along with the development of Medical Technology, present lacrimal surgery tends to Minimally Invasive Surgery mostly gradually, but Minimally Invasive Surgery just exists the problem of surgical field of view and skill aspect, and also higher to the requirement of training equipment.Do tear channel pipe implant surgery and visit when logical implantation is adopted manages, more difficult when adopted pipe is pulled out from nasolacrimal duct opening, sometimes may need one hour, but the long uncomfortable anxiety of patient that not only can make of operating time is more unfavorable for operation, and also large to patient trauma.Large hospital is used conchoscope direct-view test to get justice pipe conventionally, and instrument and equipment requires high, and surgery cost is also high, is not easy to basic hospital and popularizes because of instrument and equipment costs constraints.
Summary of the invention
The problem existing for solving above-mentioned prior art, this utility model provides a kind of lacrimal surgery device, this installation cost is low, while using this device, need not use the just position of the accurate positioning metal probe of energy of conchoscope, improve operation efficiency and effect, reduce operating time, reduce the injury bringing to patient because of operation.
The technical scheme that realizes this utility model above-mentioned purpose is:
A kind of lacrimal surgery device, at least comprise lacrimal passage drainage tubes and metal crochet hook, lacrimal passage drainage tubes comprises two metal probes, one end of two metal probes is the bulb that is spherical shape, the other end connects by silica gel tube, the middle part of each bulb is provided with two equal and opposite in directions, orthogonal magnetic hole, two magnetic holes are all perpendicular to the needle tubing of metal probe, on the tube wall at metal crochet hook needle tubing both ends, be respectively equipped with the magnetic boss that two cross section sizes and magnetic hole cross section size match, be positioned at the axle center of two magnetic boss of the same end of metal crochet hook on same straight line.
The cross section of described magnetic hole and magnetic boss is all rounded.
The material of described metal probe and metal crochet hook needle tubing is rustless steel, and the material of magnetic hole and magnetic boss is neodymium iron boron.
The perforate direction in the magnetic hole on two metal probes is identical between two.
As shown from the above technical solution, in this device, on the magnetic boss of metal crochet hook and metal probe bulb, the material of the inwall in magnetic hole all adopts neodymium iron boron, neodymium iron boron is strong magnetic material, thereby the magnetic boss of metal crochet hook and the magnetic hole of metal probe bulb be all with ferromagnetism, and the cross section of magnetic boss size matches with magnetic hole cross section size.While carrying out lacrimal surgery, by two metal probes of lacrimal passage drainage tubes respectively from upper, when lower puncta inserts nasolacrimal duct to intranasal, with the magnetic boss at metal crochet hook both ends, attract respectively the bulb of two metal probes, because effect magnetic boss and the magnetic hole of magnetic force attracts each other, the magnetic boss of metal crochet hook one end portion is sleeved in a magnetic hole of a metal probe wherein, the magnetic boss of the other end is sleeved in a magnetic hole of another root metal probe, again the two ends of metal crochet hook are pulled outward, thereby two metal probes are pulled out external, while pulling two metal probes, nasal cavity also can be pulled out in the two ends of silica gel tube, outside nasal cavity, tied a knot in the two ends of silica gel tube, silica gel tube is retraction nasal cavity voluntarily.Therefore, while using this device, do not use conchoscope just can use the position of the accurate positioning metal probe of metal crochet hook, improve surgical effect and efficiency, and then raising success rate of operation, reduced operating time simultaneously, alleviate the painful and uncomfortable of patient during operation, also reduced the injury bringing to patient because of operation.And this apparatus structure is simple, material used is common materials, thereby this installation cost is lower.

The specific embodiment
Below in conjunction with accompanying drawing, this utility model is specifically described.
The lacrimal surgery device that this utility model provides comprises lacrimal passage drainage tubes and metal crochet hook 5, lacrimal passage drainage tubes comprises two metal probes 1, one end of two metal probes is the bulb 3 that is spherical shape, the other end connects by silica gel tube 2, the middle part of the bulb of metal probe is provided with two equal and opposite in directions, mutually magnetic hole 4 and the magnetic hole 5 of vertical and magnetic, the cross section in magnetic hole 4 and magnetic hole 5 is rounded, and the magnetic hole 4 of two bulbs and the opening direction in magnetic hole 5 can be identical, also can be different.Magnetic hole 4 and magnetic hole 5 are all perpendicular to the needle tubing of metal probe, as shown in Figure 1.Magnetic hole 4 and magnetic hole 5 are all positioned at the middle part of bulb and perpendicular to the needle tubing of metal probe, the magnetic boss that such structure is conducive to metal crochet hook more attracts it, and then be more conducive to location, and further shorten operating time, improve success rate of operation.On the tube wall at metal crochet hook 6 needle tubing both ends, be respectively equipped with the magnetic boss 7 that two cross section sizes and magnetic hole 4 cross section sizes match, the cross section of magnetic boss 7 is rounded, be positioned at the axle center of two boss of metal crochet hook 6 same ends on same straight line, as shown in Figures 2 and 3.
In the present embodiment, the material of the needle tubing of metal probe and metal crochet hook is rustless steel, the material of the inwall in magnetic hole 4 and magnetic hole 5 and magnetic boss is neodymium iron boron, neodymium iron boron has excellent magnetic property and good mechanical property, thereby magnetic hole 4, magnetic hole 5 and magnetic boss 7 are all with ferromagnetism, the magnetic force attracting each other is also more intense, is conducive in operation, the spy of metal probe be got.
The method that the lacrimal surgery device that uses this utility model to provide is performed the operation is:
First in expansion, lower puncta, by two metal probes of lacrimal passage drainage tubes respectively from upper, when lower puncta inserts nasolacrimal duct to intranasal, with the magnetic boss at metal crochet hook both ends, attract respectively the bulb of two metal probes, because the effect magnetic boss of magnetic force and magnetic hole 4 and magnetic hole 5 attract each other, the magnetic boss of metal crochet hook one end portion is sleeved in the magnetic hole 4 or magnetic hole 5 of a metal probe wherein, the magnetic boss of the other end is sleeved in the magnetic hole 4 or magnetic hole 5 of another root metal probe, again the two ends of metal crochet hook are pulled outward, thereby two metal probes are pulled out external, while pulling two metal probes, nasal cavity also can be pulled out in the two ends of silica gel tube, outside nasal cavity, tied a knot in the two ends of silica gel tube, silica gel tube is retraction nasal cavity voluntarily.
