Description
Technical field
This utility model relates to medical instruments field, and a kind of double-cavity ovum taking device specifically is provided.
Background technology
Getting egg apparatus is one of the most frequently used medical apparatus and instruments that arrives in the infertility disease treatment process, mainly is made of puncture needle, handle, collecting pipe etc., and the negative pressure that can utilize the formation of negative pressure absorber is with the follicle sucking-off.This structure is got egg apparatus and had the following disadvantages: one, with after most of oocyte sucking-off, the remaining oocyte that is attached on the ovary tissue is difficult to sucking-off, influences the oocytes collection rate; Two, in order to strengthen echo effect, puncture needle head end of the prior art all can be provided with two sections ultrasonic echo districts, yet in the actual mechanical process, the setting in two sections echo districts usually can be upset doctor's sight line, easily causes misjudge.
Summary of the invention
This utility model is at above-mentioned the deficiencies in the prior art, a kind of oocytes collection rate height is provided, is convenient to the double-cavity ovum taking device that the doctor accurately judges.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of double-cavity ovum taking device, comprise puncture needle, handle, the oocytes collection pipe, sealing-plug, negative pressure Connection Block and negative pressure connection tube, handle is fixed on the puncture needle handheld terminal, oocytes collection Guan Yiduan joins by handle and puncture needle, the other end passes sealing-plug, one through hole is set on sealing-plug, one end of negative pressure connection tube and the through hole on the sealing-plug join, the other end of negative pressure connection tube and negative pressure Connection Block join, be characterized in
Described puncture needle is the two-chamber puncture needle, and a chamber is for getting the ovum passage, and another chamber is an irrigation channel;
Be penetrated with main channel and secondary channels in the described handle;
The ovum passage of getting of puncture needle is connected with the oocytes collection pipe by the handle main channel; The irrigation channel of puncture needle is connected with flushing collecting pipe one end by the handle secondary channels, and the flushing collecting pipe other end is established the syringe pipe Connection Block.
Further,
Outside puncture needle, protective casing can be set.
Described puncture needle is socketed to form by nook closing member, needle tubing, and nook closing member becomes " recessed " font, for getting the ovum passage, constitutes irrigation channel between nook closing member and the needle tubing in the nook closing member.
Described puncture needle head end is provided with one section ultrasonic echo district, and the length in ultrasonic echo district is 2～50mm.
Double-cavity ovum taking device of the present utility model is compared with prior art, has following outstanding beneficial effect:
(1) is provided with washing capacity, is easy to the remaining oocyte sucking-off that to be attached on the ovary tissue, oocytes collection rate height;
(2) two sections ultrasonic echo districts with the puncture needle head end change one section into, and the strict echo section length that limits, and on the one hand, under the situation that guarantees enough echo intensity, are more conducive to the doctor and make accurate judgement, on the other hand, can effectively reduce patient's discomfort.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model double-cavity ovum taking device;
Accompanying drawing 2 is A-A section structure for amplifying sketch maps of double-cavity ovum taking device shown in Figure 1.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
Shown in accompanying drawing 1,2, the double-cavity ovum taking device is made of puncture needle 1, handle 2, oocytes collection pipe 3, sealing-plug 4, negative pressure Connection Block 5, negative pressure connection tube 6, flushing collecting pipe 7, syringe pipe Connection Block 8 and protective casing 9.
Described puncture needle 1 is the two-chamber puncture needle, is socketed to form by nook closing member 1-1, needle tubing 1-2.Nook closing member 1-1 becomes " recessed " font.For getting the ovum path 10, constitute irrigation channel 11 between nook closing member 1-1 and the needle tubing 1-2 in the nook closing member 1-1.Puncture needle 1 head end is provided with the ultrasonic echo district 12 that a segment length is 10mm.
Be penetrated with main channel and secondary channels in the described handle 2.
Handle 2 is fixed on the handheld terminal of puncture needle 1.
Oocytes collection pipe 3 is connected with the ovum path 10 of getting of puncture needle 1 by handle 2 main channels.Oocytes collection pipe 3 other ends pass sealing-plug 4.Open a through hole on sealing-plug 4, an end of negative pressure connection tube 6 and the through hole on the sealing-plug 4 join.The other end of negative pressure connection tube 6 and negative pressure Connection Block 5 join.
Flushing collecting pipe 7 one ends are connected with the irrigation channel 11 of puncture needle 1 by handle 2 secondary channels.Flushing collecting pipe 7 other ends are connected with syringe pipe Connection Block 8.
Protective casing 9 is socketed in outside the puncture needle 1.
During use, at first one test tube is set, negative pressure Connection Block 5 and negative pressure absorber are joined at sealing-plug 4 places; Then puncture needle 1 is fixed on the B ultrasonic transvaginal probe, and insert vagina thereupon, on the B ultrasonic display screen, promptly can see the image in cellular ovary and ultrasonic echo district, puncture needle 1 end 12 this moment, the doctor just can be according to the puncture needle 1 on this manipulated image probe, the negative pressure of utilizing the negative pressure absorber to form is aspirated each follicle successively, and the bubble liquid of sucking-off enters test tube along oocytes collection pipe 3.When the remaining oocyte on being attached at ovary tissue is difficult to sucking-off, can utilizes syringe to inject an amount of flushing liquor, and then repeat above-mentioned aspiration procedure, extract remaining oocyte out by washing collecting pipe 7.
Above-described embodiment, this utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
