Description
Technical field
This utility model relates to a kind of apparatus of obstructed lacrimal passage intubate operation, relates in particular to a kind of obstructed lacrimal passage operation line sending pin.
Background technology
Lacrimal probe has following three classes at present: one, the probe that blocks lacrimal passage is led to, enlarged to simple the spy, and shortcoming is to excise and to carry the lacrimal passage lead-in wire simultaneously; Two, can visit logical lacrimal passage and also can excise the probe that blocks the lacrimal passage scar tissue, shortcoming is to carry the lead-in wire that is used for lacrimal passage intubation simultaneously; Three, can visit the logical probe that blocks lacrimal passage and can carry the lacrimal passage intubation lead-in wire simultaneously, advantage is obviously to shorten the lacrimal passage intubation operating time, and shortcoming is to excise the scar tissue that blocks lacrimal ductule and nasolacrimal duct simultaneously.With the intubate operation that this probe is finished, can push the flexible pipes such as silica gel tube that insert lacrimal passage because of the scar tissue of occluded segment and cause operative failure.
Therefore, be necessary to design a kind of scar tissue that can excise the obstruction lacrimal passage, can help to carry the obstructed lacrimal passage operation line sending pin of the required lead-in wire of lacrimal passage intubation again.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of operation is easier, taking into account simultaneously of better effects if visit logical lacrimal passage and excision and block the scar tissue of lacrimal passage, can carry the obstructed lacrimal passage operation line sending pin of lacrimal passage intubation lead-in wire again.
For solving the problems of the technologies described above, adopt following technical scheme:
Obstructed lacrimal passage operation line sending pin, comprise set gradually from top to bottom push away medicated cap, push rod, pushing cylinder lid, pushing cylinder, cut somebody's hair, needle tubing, nook closing member; Described medicated cap and the push rod of pushing away is to be threaded described pushing cylinder lid and tighter interference fits or the interference fit of pushing cylinder; Described push rod and pushing cylinder matched in clearance; Described nook closing member places in the tube wall of its needle tubing; Described needle tubing lower end tube wall is provided with a needle tubing tube wall side mouth, and its termination is provided with interior chamfering, and chamfering forms sharp trepan cutter in this.
Described needle tubing tube wall side mouth is located at its needle tubing apart from its end tube wall 4～5mm place.
The long 1.5m of described needle tubing tube wall side mouth, wide 0.9mm.
Described nook closing member from then on needle tubing tube wall side mouth penetrates, pass through needle tubing and from the needle tubing upper end, the invagination in described nook closing member lower end forms the little ring of ellipse garden shape, draw its nook closing member upper end to put in place and with cut somebody's hair fixing after, this ellipse garden little ring of shape just is imbedded in the needle tubing tube wall side mouth.
Like this, can guarantee that needle tubing inserts the smoothness of lacrimal passage.
The described medicated cap that pushes away, push rod, pushing cylinder lid, pushing cylinder, cut somebody's hair and needle tubing) all to make with medical aluminium alloy, described nook closing member is bifilar nickel-titanium metal silk or medical steel wire.
So, operating theater instruments uses is convenient to cleaning-sterilizing, can guarantee the safety of performing the operation.
Because following cause: one, the needle tubing lower end is designed to both can detect the obstructed lacrimal passage section sharp trepan cutter that again can excision lacrimal passage scar tissue; Two, this probe side mouth is hollow with hypomere, both can get rid of the scar tissue of cutting-out, can provide another outlet when titanium silk or medical steel wire stylet head change wrong direction again, guarantees that operation carries out smoothly; Three, titanium silk or medical steel wire stylet upper end cutting somebody's hair thin and light, can prevent that nook closing member from coming off, and gravity pressure looper core and smoothness when influencing lock pin; Operation was finished in five minutes.
Therefore, the beneficial effects of the utility model are: can improve obstructed lacrimal passage intubate operative effect, and shorten operating time.
Description of drawings
Below in conjunction with the drawings and the specific embodiments this utility model is described in further detail.
Fig. 1 is this utility model structure cutaway view;
Fig. 2 is this utility model decomposition texture sketch map;
Fig. 3 is the B portion enlarged drawing of Fig. 1;
Fig. 4 is the A portion enlarged drawing of Fig. 1.
Accompanying drawing sign: push away medicated cap 1, push rod 2, pushing cylinder lid 3, pushing cylinder 4, cut somebody's hair 5, needle tubing 6, needle tubing tube wall side mouth 61, interior chamfering 62, nook closing member 7, the little ring 8 of ellipse garden shape.
The specific embodiment
As depicted in figs. 1 and 2, obstructed lacrimal passage operation line sending pin, comprise set gradually from top to bottom push away medicated cap 1, push rod 2, pushing cylinder lid 3, pushing cylinder 4, cut somebody's hair 5, needle tubing 6, nook closing member 7; Described medicated cap 1 and the push rod 2 of pushing away to be being threaded, interference fits or interference fit that described pushing cylinder lid 3 and pushing cylinder 4 are tighter; Described push rod 2 and pushing cylinder 4 matched in clearance; Described nook closing member 7 places in the tube wall of its needle tubing 6; Described needle tubing 6 lower end tube walls are provided with a needle tubing tube wall side mouth 61, and its termination is provided with interior chamfering 62, and chamfering 62 forms sharp trepan cutter in this.
Referring to Fig. 1, described needle tubing tube wall side mouth 61 is located at its needle tubing 6 apart from its end tube wall 4～5mm place; Described needle tubing tube wall side mouth 61 long 1.5m, wide 0.9mm.Described nook closing member 7 from then on needle tubing tube wall side mouth 61 penetrates, pass through needle tubing 6 and from needle tubing 6 upper ends, the invagination in described nook closing member 7 lower ends forms the little ring 8 of ellipse garden shape, draw its nook closing member 7 upper ends to put in place and with cut somebody's hair 5 fixing after, the little ring 8 of this ellipse garden shape just is imbedded in the needle tubing tube wall side mouth 61.
The described medicated cap that pushes away 1, push rod 2, pushing cylinder lid 3, pushing cylinder 4, cut somebody's hair 5 and needle tubing 6 all make with medical aluminium alloy, needle tubing 6 is No. 9 puncture needle tubings, the bifilar nickel-titanium metal silk of nook closing member 7 for passing needle tubing 6 and can spurring easily up and down.
This obstructed lacrimal passage operation line sending pin, because:
1. the needle tubing lower end is designed to both can detect the obstructed lacrimal passage section, can performs the operation again except that the probe of lacrimal passage scar tissue;
2. this probe side mouth is hollow with hypomere, both can get rid of the scar tissue of cutting-out, can provide another outlet when the wire needle core print changes wrong direction again, guarantees to perform the operation and carries out smoothly;
Steel wire stylet upper end cutting somebody's hair thinly and light, can prevent that nook closing member from coming off, and gravity pressure looper core and smoothness when influencing lock pin.
Therefore, that this obstructed lacrimal passage operation line sending pin will be visited will be logical, operation lacrimal passage scar tissue excision and carry three kinds of functions of lacrimal passage intubation lead-in wire to combine together, can obviously shorten operating time, the raising operative effect.
Above content be in conjunction with concrete preferred implementation to further describing that this utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from this utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
