Abstract

The utility model discloses a probe conducting wire combined lacrimal probe which comprises a probe conducting wire capable of being inserted into the probe pipe and freely pulled up and down in the probe pipe. The probe conducting wire is made of titanium-nickel alloy with the proportion ratio of 50 is received developed heat-treatment technology to enhance the memory, the elasticity and the ductility, and adopts a flat shape. The proportion ratio in the titanium-nickel alloy is more scientific and self-developed heat-treatment is adopted, so that the memory, the elasticity and the ductility are greatly improved, the operation is easy and fracture is less possible to occur; and the use function of the J shape adopted by the probe conducting wire and the spoon-shaped curve at the front of the conducting wire, as well as the angle of a hole formed on the side wall of the lacrimal probe are improved, so that the probe conducting wire can extend in place along the nasal vestibule.

Description

Memory guide wire combined type lacrimal probe

Technical field:

This utility model patent relates to the ophthalmology technical field in the clinical medicine, relates to the retrograde pipe operating theater instruments of putting of a kind of probing of lacrimal passages and Wicresoft

Technical background:

The tube placing operation treatment obstructed lacrimal passage disease of driving in the wrong direction is former in " nasal cavity lachrymal sac art ", " nasolacrimal anastomosis ".The focus of the research of obstructed lacrimal passage treatment in recent years.As seen principle of uniformity, the lacrimal passage of different tool and methods are put when the clinical report of obstructed lacrimal passage is treated in governance has.The tube placing device material has the following disadvantages but lacrimal passage of the prior art drives in the wrong direction: require to put the operating technology of the ophthalmologist of pipe operation with ear larynx doctor; Need to take out guide wire or guide wire from the nasolacrimal duct end opening of hiding very much by frontal mirror, nasal speculum, finish this operation, even otorhinolaryngology specialist, certain difficulty is also arranged sometimes, the eye specialist more feels operating difficulties, this causes prolonging operating time, increases patient's misery or causes epistaxis, even end operation.In order to solve this deficiency, my patent No. is: 01243167.2 improves, but the angle of its nook closing member elasticity and areole causes and stretch before the nose not in placely, and nook closing member causes problems such as inconvenience because of the not enough easy fracture of toughness.

The utility model content

This utility model patent has been done significant improvement to memory material and seal wire processing Technology for Heating Processing, purpose makes this product further perfect, having solved angle because of memory guide wire Memorability, elasticity and areole causes nasal vestibule and stretches not in place, nook closing member is because of the not enough easy fracture of toughness, the inconvenience that causes, even end problem such as operation.

This utility model patent is to be achieved through the following technical solutions:

A kind of memory guide wire combined type lacrimal probe comprises inserting in the probe body pipe, and can be in the probe body pipe free memory guide wire of pulling up and down, and described memory guide wire respectively is 50% alloy composition with titanium, nickel proportioning.

Described memory guide wire is handled through development test Technology for Heating Processing voluntarily, to strengthen its Memorability, elasticity and toughness.

Described memory guide wire body is a flat.

Compared with prior art, this utility model patent has following effect: because nickel, titanium alloy proportioning science more, and through development test heat treatment voluntarily, improved its Memorability, elasticity and toughness greatly, easy operating, easy fracture not; Improved crooked function of use of the preceding spoon of memory guide wire J-shaped shape and seal wire shape and lacrimal probe areole angle has been set, be easier to make memory guide wire to cause nasal vestibule and stretch put in place (described memory guide wire core technology surgical operation step).

Description of drawings

The drawing of accompanying drawing is described as follows:

Fig. 1 is the crooked and J-shaped hook sketch map of this utility model patent memory guide wire top spoon shape;

Fig. 2 is described memory guide wire and probe combinations direction sketch map;

Fig. 3 is an operating position sketch map after described seal wire and the probe combinations;

Fig. 4 is that described memory guide wire is pushed out the sketch map that stretches to nasal vestibule behind the probe side ancient piece of jade, round, flat and with a hole in its centre hole;

Fig. 5 is the enlarged diagram of A portion among Fig. 2.

The specific embodiment

Below in conjunction with the best implementation and operation step shown in the accompanying drawing:

A kind of combination type probing of lacrimal passages pin adds memory guide wire, shown in Fig. 1 to 5, comprise probe 1 and contrary the memory guide wire 2 that in probe tube, also can freely spur within it, needle tip 105 sealings of described probe tube 1 are conical, the entity section 101 that certain-length is arranged in it, the upper surface 102 of this entity section is downward-sloping, continue and have areole 103 on the tube wall of described upper surface, the lower edge on this adjacent described inclined-plane of areole, above-mentioned inclination becomes the obtuse angle with the rear wall of areole, and the length of described entity section 101 is 3-7mm.

In order not damage nasal mucosa, and can guide out lacrimal point with Y shape lacrimal passage expansion drainage tube draught line, memory guide wire 2 is to be made by the bifilar alloy silk of the J-shaped curved hook that can remember original front end, its cross sectional shape is circular, in order to increase its Memorability, elasticity and toughness, carry out corresponding heat treatment technics to memory guide wire 2.

As shown in Figure 1, the lower end of memory guide wire 2 is bent and is approximate J-shaped shape, and its bending diameter is 2-8mm.As shown in Figure 5, described inclined plane 102 is the 130-160 degree with the angle that rear wall was of areole.

In order to allow memory guide wire accurately stretch out nasal vestibule, as shown in Figure 4, the upper end 104 of described probe tube is provided with labelling " 9 " (exposing the part more than lacrimal point during operation), and this face should be consistent with the direction of probe side cinclides.

When this utility model patent is used, be that 01243167.2 probing of lacrimal passages guid needle is identical with my patent No..To treat the eye local anaesthesia earlier, this probe of reuse is visited logical lacrimal passage, order is pointed to nasal vestibule (being the one side sensing nasal vestibule that the probe upper end is provided with labelling) near the areole of entity syringe needle, send memory guide wire to move ahead to entity syringe needle direction downwards, memory guide wire just accurately stretches out nasal vestibule voluntarily under the control of slope and guiding.Then, the draught line of the lacrimal passage that will implant expansion drainage tube passes between two strands of the memory guide wires, and when upwards drawing the seal wire feel that resistance is arranged, memory guide wire lifts until draught line is pulled out lacrimal point with the probing of lacrimal passages pin.Again Y-piece is implanted lachrymal sac, after cutting off draught line and Y-piece and exposing part on the nose, whole Minimally Invasive Surgery has just been finished.
