It is a kind of disposably to use endoscope specimen fetching bag
Technical field:
The present invention relates to the technical fields of medical instrument, and endoscope specimen fetching is disposably used more specifically to a kind of
Bag.
Background technology:
When diagnosing the illness accurately to find the cause of disease, biopsy need to be carried out to lesion, doctor is with medical apparatus from lesion
It is middle to obtain a certain amount of living tissue progress pathological analysis, so as to symptomatic treatment.Utensil common in the prior art is to play rifle
Formula biopsy needle, this device make biopsy needle in intralesional carry out biopsy by the release of built-in spring;In various upper measures when use, such as
Biopsy needle is punctured to lesion under the guiding such as B ultrasound, CT, then release spring, biopsy needle then quickly in intralesional puncture, if one
It is secondary not obtain tissue, then it needs to repeat above-mentioned action, increases damage probability;Simultaneously as dynamics is made of spring, it is difficult to control and lives
Examine the depth etc. of needle.To need corresponding more convenient simple endoscope sample extraction element.
Invention content:
The purpose of the present invention and provides aiming at the deficiency of the prior art and a kind of disposably using endoscope specimen fetching
Bag facilitates realization to realizing that extraction makes a collection of specimens in vivo.
To achieve the above object, the technical solution adopted by the present invention is as follows:
It is a kind of that endoscope specimen fetching bag, including intubation, the bottom end plugged and fixed of intubation is disposably used to have the guiding of T-type
Head forms slot in the middle part of guide head, and vertical nutted rod is plugged in the slot of guide head, and the lower end of nutted rod, which is stretched out, leads
Bifurcated is formed to head, is inserted with specimen bag outside bifurcated, the sack of specimen bag is sewed with necking, and the end of bifurcated is resisted against sample
In the necking of bag, drawstring is plugged in the necking of specimen bag;The upper end of the nutted rod is plugged in intubation and is fixed on cross bar,
Vertical guide groove is formed on the side wall of the intubation of cross bar both sides, the both ends of cross bar pass through the guide groove of intubation to be fixed on activity
It puts on, movable sleeve sleeve is in intubation;
Form jack on the guide head of the nutted rod both sides, it is slotting that the both ends of drawstring pass through the jack of guide head to be plugged in
It in pipe and is fixed in the spacing head of T-type, spacing head is plugged on the upper end of intubation, and the upper end of spacing head forms draw ring, limit
The intubation upper sleeve of head downside is fixed with fixing sleeve, and finger-stall is formed on the opposite outer wall of fixing sleeve.
Preferably, the end of bifurcated forms notch on the nutted rod, and the necking of specimen bag is plugged in the notch of bifurcated
It is interior.
Preferably, the lower end for being oriented to head insertion slot forms the opening of taper, and the inclined-plane of the opening of slot taper tilts
In the angle of inclination of bifurcated on the nutted rods such as angle.
Preferably, the lower end of jack is formed to the inclined inclined hole of guide head outer side edges on the guide head.
Preferably, the length of bifurcated is equal to the length for being intubated upper guide groove on the nutted rod.
Preferably, there are two vias, via to be distributed in the both sides of nutted rod for molding on the cross bar, and drawstring is plugged in cross
In the via of bar.
The beneficial effects of the present invention are:Its is simple in structure, facilitates realization to realizing that extraction makes a collection of specimens in vivo, convenient for pair
The assay of pathology is studied.

Specific implementation mode:
Embodiment:As shown in Figure 1, a kind of disposably to use endoscope specimen fetching bag, including intubation 1, the bottom end for being intubated 1 is inserted
The guide head 2 for being fixed with T-type is connect, the middle part of guide head 2 forms slot 21, and it is vertical to be plugged in the slot 21 of guide head 2
Nutted rod 3, the lower end of nutted rod 3 stretch out guide head 2 and form bifurcated 31, and specimen bag 7 is inserted with outside bifurcated 31, specimen bag 7
Sack is sewed with necking 71, and the end of bifurcated 31 is resisted against in the necking 71 of specimen bag 7, is plugged in the necking 71 of specimen bag 7
Drawstring 8;The upper end of the nutted rod 3 be plugged in intubation 1 in be fixed on cross bar 4, on the side wall of the intubation 1 of 4 both sides of cross bar at
Type has vertical guide groove 11, the both ends of cross bar 4 that the guide groove 11 of intubation 1 is passed through to be fixed on movable sleeve 5,5 sleeve of movable sleeve
In intubation 1;
Jack 22 is formed on the guide head 2 of 3 both sides of the nutted rod, the both ends of drawstring 8 pass through the jack 22 of guide head 2
Be plugged in intubation 1 and be fixed in the spacing head 9 of T-type, spacing head 9 is plugged on the upper end of intubation 1, the upper end of spacing head 9 at
Type has draw ring 91,1 upper sleeve of intubation of 9 downside of spacing head to be fixed with fixing sleeve 6, hand is formed on the opposite outer wall of fixing sleeve 6
Fingerstall 61.
Preferably, the end of bifurcated 31 forms notch on the nutted rod 3, and the necking 71 of specimen bag 7 is plugged in bifurcated
In 31 notch.
Preferably, the lower end of 2 slot 21 of the guide head forms the opening 211 of taper, the opening 211 of 21 taper of slot
The nutted rods 3 such as bevel inclination angle in the angle of inclination of bifurcated 31.
Preferably, the lower end of jack 22 is formed to the inclined inclined hole of 2 outer side edges of guide head 221 on the guide head 2.
Preferably, the length of bifurcated 31 is equal to the length for being intubated guide groove 11 on 1 on the nutted rod 3.
Preferably, there are two vias 41, via 41 to be distributed in the both sides of nutted rod 3, drawstring 8 for molding on the cross bar 4

Operation principle:The present invention is disposably to use endoscope specimen fetching bag, uses disposable, is avoided that repetition
Using infection, in use, first pulling up movable sleeve 5, realize that the bifurcated 31 of nutted rod 3 is contracted in guide head 2, and pull draw ring
91, it realizes that specimen bag 7 is shunk, then intubation 1 is plugged at sample extraction in vivo, movable sleeve 5 is set aside, realize bifurcated 31
Guide head 2 is removed, the sack of specimen bag 7 is opened, so as to collect specimen, after extraction, bifurcated 31 is stored, draws draw ring
91, realize that the sack of specimen bag 7 collapses, to realize that it is external that sample takes out.
The embodiment is to be illustrated the present invention, and is not intended to limit the present invention.Any those skilled in the art
It can modify without violating the spirit and scope of the present invention to the embodiment, therefore the rights protection model of the present invention
