Description

One gets ovum pin

Technical field:

This utility model relates to medical appurtenance technical field, and the one specifically for vitro fertilization-embryo implanting operation gets ovum pin.

Background technology:

Along with the develop rapidly of auxiliary procreation technology, tube-test baby techniques relies on high-end technical guarantee and rigorous scientific procedure, more and more obtain the favor of numerous sterility and infertility Mr. and Mrs, but the operation of this growing demand to ova harvest is had higher requirement, method general at present under hyperacoustic guiding, adopts single use to get ovum pin transvaginal puncture get ovum.

During clinical ova harvest, often to repeatedly repeat through vaginal wall and ovary to obtain more ovum, this just causes the easy rust of needle point or distortion or produces agnail, not only make troubles to operator, also can bring misery to patient, even cause site of puncture hemorrhage, so ovum pin needle point will be asked for still keep enough sharpness after repeatedly puncturing, be beneficial to the location of pin, puncture and sucking-off follicle, this just needs good needle point sword face design to meet.

Clinical needs get ovum pin total length between 350 ~ 500mm, so long needle tubing is made to be convenient to surgical staff operation, needle tubing external diameter just sufficiently large guarantee reach suitable rigidity, and the larger needle tubing of external diameter can strengthen the puncture marks of patient, naturally brings larger pain.

Utility model content:

In order to overcome the many drawbacks existing for above-mentioned prior art, the purpose of this utility model is, provides one to get ovum pin.

This utility model solves the technical scheme that its technical problem adopts: one gets ovum pin, comprise the needle tubing Part II that needle tubing Part I and needle tubing Part I one is connected, the needle point of described needle tubing Part I is provided with the first tangent plane and the second tangent plane, the needle point point of described first tangent plane and the second tangent plane is not got on the axis of ovum pin length direction on edge, and the diameter of described needle tubing Part I is less than the diameter of needle tubing Part II.

Further, the long 40 ~ 60mm of the diameter of described needle tubing Part I.

Further, described needle point coating silica gel lubricating layer.

Compared with prior art, its beneficial effect is this utility model:

1, operating theatre staff when repeatedly repeating through vaginal wall and ovary to obtain more ovum, first the position contacting patient is the tangent plane of needle point, instead of needle point point, the pin of the most sharp point of needle point is utilized to compare with existing ovum pin of getting, more smoothly also leniently can puncture into desired location, not easily make needle point rust or distortion or produce agnail easily, not easily cause site of puncture hemorrhage, can still keep enough sharpness after repeatedly puncture.

2, the diameter design of needle tubing body 2 part has size, compared with the existing needle tubing getting ovum pin, needle tubing Part I 1 external diameter is less, to reduce in operation process to the puncture marks that patient brings, also the pain of patient can effectively be reduced, the diameter of needle tubing Part II 2 is comparatively large, can have enough rigidity and toughness in operating theatre staff uses.

3, needle point is coated with silica gel lubricating layer, can complication be reduced with existing getting compared with ovum pin, the pain effectively reducing patient by and strengthen the operability of surgical staff.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is needle point enlarged diagram of the present utility model.

Detailed description of the invention:

As shown in Figure 1, one gets ovum pin, and comprise the needle tubing Part II 2 that needle tubing Part I 1 is connected with needle tubing Part I 1 one, described needle tubing Part I 1 needs to enter in patient body in use, and described needle tubing Part II 2 is exposed external in use.The needle point 3 of described needle tubing Part I 1 is provided with the first tangent plane 4 and the second tangent plane 5, the needle point point 6 of described first tangent plane 4 and the second tangent plane 5 is not got on the axis of ovum pin length direction on edge, described tangent plane needle point point 6 is arranged on the right direction of the axis of getting ovum pin length direction, and namely needle point tangent plane is asymmetrical.Operating theatre staff when repeatedly repeating through vaginal wall and ovary to obtain more ovum, the position first contacting patient is the tangent plane of needle point, instead of needle point point 6, not easily makes needle point rust or distortion or produce agnail easily.

The diameter of described needle tubing Part I 1 is less than the diameter of needle tubing Part II 2, and needle tubing Part I 1 external diameter is less, to reduce to the puncture marks that patient brings in operation process, also effectively can reduce the pain of patient.The diameter of described needle tubing Part II 2 is comparatively large, can have enough rigidity and toughness in operating theatre staff uses.

The length of described needle tubing Part I 1 is 50mm.

Described needle point 3 applies silica gel lubricating layer, can reduce complication, and the pain effectively reducing patient is subject to and strengthens the operability of surgical staff.

The operation principle of embodiment is as follows:

In operation, operating theatre staff holds needle tubing Part II 2, by the first tangent plane 4 and the second tangent plane 5 of needle point 3 on Part I 1, carries out puncture working to the position that tactile needs of patients punctures.

The present embodiment is compared with prior art:

1, operating theatre staff when repeatedly repeating through vaginal wall and ovary to obtain more ovum, first the position contacting patient is the tangent plane of needle point, instead of needle point point, the pin of the most sharp point of needle point is utilized to compare with existing ovum pin of getting, more smoothly also leniently can puncture into desired location, not easily make needle point rust or distortion or produce agnail easily, not easily cause site of puncture hemorrhage, can still keep enough sharpness after repeatedly puncture.

2, the diameter design of needle tubing body 2 part has size, compared with the existing needle tubing getting ovum pin, needle tubing Part I 1 external diameter is less, to reduce in operation process to the puncture marks that patient brings, also the pain of patient can effectively be reduced, the diameter of needle tubing Part II 2 is comparatively large, can have enough rigidity and toughness in operating theatre staff uses.

3, needle point is coated with silica gel lubricating layer, can complication be reduced with existing getting compared with ovum pin, the pain effectively reducing patient by and strengthen the operability of surgical staff.

Above content is described in further details technical scheme of the present utility model in conjunction with detailed description of the invention; can not assert that concrete enforcement of the present utility model is confined to these explanations above-mentioned; for those skilled in the art; under the prerequisite not departing from this utility model essential idea; make some deductions or do not replace from the equivalence of essence, all should be considered as protection domain of the present utility model.
