Abstract
A leading-in tool for the uterus of female-goat is composed of a straight cylindrical tube and an arc tubular leading head with the gradually reduced flat-elliptic cross-section. Its advantages are simple structure and high leading-in effect.
Description
Technical field
The present invention relates to be applied to deep, goat uterus input seminal fluid or embryo transfer operation, can pass through sheep cervical canal labyrinth, import the import tool in body of uterus and the cornua uteri.
Background technology
At present, the import tool in known sheep uterus is that a cylindrical tube has a bending at its close end, and the cylindrical tube opening, imports head and probes into the external os of vervix when implementation and operation on the top, carries out the semen deposition of cervical canal superficial part.The all ages and classes ewe is because the difference of cervical canal mucosa gauffer anatomical structure characteristics and the variation of anatomical structure thereof, the general head that imports can not or partly enter the uterus by cervical canal, causes difficulty for the operation in cervical canal deep, body of uterus or cornua uteri.
Summary of the invention
The objective of the invention is: overcome the shortcoming that existing import tool is difficult to guarantee effectively to pass through sheep cervical canal labyrinth, providing a kind of can smoothly, effectively pass through the goat cervical canal, implements the input seminal fluid of different parts in the cavity of uterus and the sheep uterus import tool of embryo transfer.
The technical pattern scheme that realizes above-mentioned purpose is such.
Sheep uterus import tool is characterized in that: the arc importing tube head by cylindrical straight tube and smooth connection is formed, and the cross section that described arc imports tube head is the flat ellipse that gradual change reduces.
The pipe end that described arc imports tube head is a blind end, and arc imports the tube head curved side, is provided with the mouth of pipe with cylindrical straight tube transitions junction, and the outside tube wall of the mouth of pipe is smooth shape.
Described arc imports tube head along the longitudinal center line of flexure plane centrage and cylindrical straight tube point-blank, and arc imports tube head both can be crooked left with respect to centrage, also bending to the right.
The concrete making is: import end in the cylindrical tube uterus, be designed to homalocephalus, the homalocephalus base portion is converted into certain angle gently, and homalocephalus length, width and thickness are different different with goat cervix uteri size, and all can enter cervical canal with homalocephalus and cylindrical tube is principle; The cylindrical tube opening is near the homalocephalus base portion, and the sideline, the outside of opening is whittled into level and smooth shape; Whole importing head surface structure is level and smooth.The principles of science of this organization plan foundation is that 1. how goat cervical canal longitudinal section is made of interlaced gauffer, it is the pass that the free edge far-end of gauffer forms narrow cervical canal, cervical canal cross section between the adjacent pass is slot-shaped, therefore the cervix uteri pass is to import the key link of tube head by cervical canal, and cervix uteri generally has 4-5 pass.When the homalocephalus shape imports tube head in slot-shaped cervical canal during turn, homalocephalus shape ingress pipe header structure has strutted slot-shaped pipeline, relaxation to cervical canal, help avoiding the obstruction of mucosa wrinkle wall to importing, strut next pass to the greatest extent, create conditions for homalocephalus shape importing tube head enters next slot-shaped cervical canal.2. the free property in uterus is bigger, the most external oses of vervix of goat and thereafter the channel angle in pass less than 90 °, cervical canal before and after the pass has blind pipe more and props up, and the pass line is not point-blank, therefore cylindrical tube and homalocephalus shape importing tube head has a certain degree, make the homalocephalus shape import tube head first and be easy to push aside the external os of vervix, turn homalocephalus shape imports tube head and enters cervical canal; In addition then its mechanics can change the cervix uteri y direction and with the position relation of homalocephalus, the obstruction of avoiding blind pipe to prop up is beneficial to visit and looks for and slide to next pass, strengthens pass opening effect; And the homalocephalus shape imports bending towards of tube head, can play a part guiding and import head importing left side or right side cornua uteri.3. sideline, the mouth of pipe of this import tool outside is whittled into the smooth of smooth shape and ingress pipe head surface structure, has reduced the damage that imports tube head antithetical phrase cervical canal mucosa.
The invention has the beneficial effects as follows, can guarantee effectively to import and pass through the goat cervical canal, import body of uterus, or left side or right side cornua uteri, import tube head and only adopt certain angle to be the homalocephalus structure of arcuation, simple structure.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated by embodiment.
Embodiment:
In Fig. 1,2, the homalocephalus shape imports tube head and is bar shaped of gradual change prolate or flat ellipse garden shape, length * wide * thick 9.0 * 2.7 * 1.2mm that is generally, the homalocephalus shape imports tube head 2 and links to each other with cylindrical straight tube 1 at homalocephalus base portion 4, and the longitudinal center line of homalocephalus shape importing tube head 2 positive face length centrages and cylindrical straight tube 1 point-blank; Opening 5 outside tube walls of cylindrical straight tube become smooth shape, and be positioned at homalocephalus base portion 4, arc 3 at homalocephalus base portion 4 makes homalocephalus shape importing tube head 2 sides bend towards left side or right side, its structure is beneficial to pushes external os of vervix gauffer 6 aside, when the homalocephalus shape imported in the tube head 2 importing cervical canal 7, cylindrical straight tube opening 5 became the port of seminal fluid or embryo's processing.
In the embodiment shown in fig. 3, press down cylindrical straight tube 1 by turn and appropriateness twitch, there are two kinds of Fundamentals to make the homalocephalus shape import tube head 2 by cervix uteri pass 8, a kind of is the position that arc 3 mechanics have changed cervical canal 7, make homalocephalus shape importing tube head 2 be beneficial to visit and look for cervix uteri pass 8, avoid the cervical canal blind pipe to prop up 9 obstruction, and produce outer group of antithetical phrase cervical clefts 6 and make the homalocephalus shape import tube head 2 and slide to and open 8 effects of cervix uteri pass; Another kind is that the homalocephalus shape that is in the slot-shaped cervical canal 7 imports tube head 2, when the position in slot-shaped cervical canal 7 by flat-shaped when transferring upright shape to, strutted slot-shaped cervical canal 7, avoiding mucosa wrinkle wall 10 hinders, it is descending to be beneficial to homalocephalus shape importing tube head 2, strut pass 8 to the greatest extent, make the homalocephalus shape import tube head 2 and can enter next slot-shaped cervical canal 7, cross whole cervical canal 7 until importing head by pass 8.
