Abstract
The utility model relates to a device for collecting sperms from a seminiferous tubule. The device is provided with a fixer and an extruder, wherein the fixer is provided with a handle and an L-shaped fixing needle connected to one end of the handle; the fixing needle is provided with graduation marks; and the extruder is provided with a handle and a runner connected to one end of the handle. The device has the advantages that: the seminiferous tubule extracting continuity is not damaged, and remaining seminiferous tubules can be applied to scientific researches such as researches of primitive spermatogonium development or collection of primitive spermatogoniums from laboratories and the like; the fixing needle is provided with graduation marks, so that a surgeon can be guided to select thick seminiferous tubules accurately; the runner is provided, so that sperms existing in seminiferous tubules can be extruded out more completely, and the sperm collecting probability is increased; and the device is simple in structure, is easy and convenient to operate, is low in manufacturing cost, and is suitable for clinical universal popularization.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of device that obtains sperm from seminiferous tubule.
Background technology
Detect male reproductive function in the reproductive medicine and differentiate that its disease adopts micro-smart art or the testis biopsy art of getting usually, needs in the art to obtain sperm through male's seminiferous tubule.Usually the method that adopts clinically at present is the Mechanical Method such as scissor cut, seminiferous tubule is shredded obtain sperm.It has following defective: (1) can destroy the seriality of taking out seminiferous tubule, is unfavorable for further research, obtains the scientific researches such as stem spermatogonium such as stem spermatogonium growth or laboratory; (2) it is low to get smart efficient, is difficult to all tubules are shredded, and also is difficult to all sperms in the tube chamber are all dissociated out; (3) the operation technique personnel only rely on range estimation to judge the seminiferous tubule size, lack effective reference hierarchy.Therefore, need a kind of success rate height, the device that from seminiferous tubule, obtains sperm reliable, time saving and energy saving and simple in structure easy and simple to handle badly, but yet there are no report about this class device at present.
Summary of the invention
The purpose of this utility model is that a kind of device that obtains sperm from seminiferous tubule is provided.
For achieving the above object, the technical scheme taked of this utility model is:
A kind ofly obtain the device of sperm from seminiferous tubule, described device is provided with holder and squeezer, and described holder is provided with handle and is connected in " L " shape locking pin of handle one end, and described squeezer is provided with handle and is connected in the runner of handle one end.
Handle one end of described squeezer is connected with the drift angle of isosceles triangle rotating shaft, and described rotaring wheeling sleeve is connected on the base of rotating shaft.
Handle one end of described squeezer is to be connected with the drift angle of isosceles triangle rotating shaft by a pitman.
Described runner is columniform.
Described locking pin is provided with scale.
The least unit of described scale is 10 μ m.
Described handle is elongated cylindrical substantially.
This utility model advantage is:
1, this utility model can not destroy and take out the seminiferous tubule seriality, and the residue seminiferous tubule can be used for studying the stem spermatogonium growth or laboratory obtains the scientific researches such as stem spermatogonium;
2, locking pin is provided with scale, can instruct the patient more accurately to select thicker seminiferous tubule;
3, be provided with runner, can more fully the sperm that exists in the seminiferous tubule be extruded, improve the probability that obtains sperm;
4, this utility model is simple in structure, and is easy and simple to handle, and low cost of manufacture is suitable for generally promoting clinically.
Description of drawings
Accompanying drawing 1 is a kind of fixer structure sketch map that obtains the device of sperm from seminiferous tubule of the present invention.
Accompanying drawing 2 is a-quadrant enlarged drawings among Fig. 1.
Accompanying drawing 3 is a kind of extruder structure sketch maps that obtain the device of sperm from seminiferous tubule of the present invention.
The specific embodiment
Below in conjunction with embodiment and with reference to accompanying drawing this utility model is further described.
The Reference numeral and the ingredient that relate in the accompanying drawing are as follows:
1. holder 11. holder handles
12. locking pin 13. scales
2. squeezer 21. squeezer handles
22. pitman 23. rotating shafts
24. runner
A kind of device that obtains sperm from seminiferous tubule of the present utility model comprises holder and squeezer.
Please refer to Fig. 1, Fig. 1 is a kind of fixer structure sketch map that obtains the device of sperm from seminiferous tubule of the present invention.Described holder 1 is provided with holder handle 11 and locking pin 12.Described holder handle 1 is elongated cylindrical substantially, and the one end is connected with locking pin 12.Described locking pin 12 bendings are L-shaped.
Please refer to Fig. 2, Fig. 2 is a-quadrant enlarged drawing among Fig. 1.The top section of described locking pin 12 is provided with scale 13, and the least unit of described scale 13 is 10 μ m.
Please refer to Fig. 3, Fig. 3 is a kind of extruder structure sketch map that obtains the device of sperm from seminiferous tubule of the present invention.Described squeezer 2 is provided with squeezer handle 21, described squeezer handle 21 is elongated cylindrical substantially, the one end is connected with an end of pitman 22, the other end of described pitman 22 is provided with rotating shaft 23, described rotating shaft 23 is isosceles triangle shapes, and pitman 22 is to link to each other with the drift angle of rotating shaft 23.Be socketed with a runner 24 on the base of described rotating shaft 23, described runner 24 is columniform.
Need to prove that described holder handle 11 and squeezer handle 21 are designed to elongated cylindrical in order to make things convenient for the operation technique personnel to grip, but are not limited only to this, can also be designed to meet hand and grip morphologic elongated cylindrical; Described locking pin 12 is " L " shape, can be conveniently fixing seminiferous tubule, can not stop the sight line of object observing thing simultaneously; Described scale 13 can be used for measuring the seminiferous tubule diameter, and then instructs the patient to obtain thicker seminiferous tubule; Described squeezer 2 also can not established pitman 22, and an end of squeezer handle 21 directly is connected with the drift angle of rotating shaft 23, but preferably between squeezer handle 21 and rotating shaft 23 pitman 22 is set, and its purpose also is for the thing visual field that fully gives away one's position.
A kind of device using method of obtaining sperm from seminiferous tubule of the present utility model is: micro-getting the smart art, cutting testis exposes after the seminiferous tubule, under operating microscope, use the scale 13 large bulk measurement seminiferous tubule diameters on the locking pin 12, to select thicker seminiferous tubule; The seminiferous tubule that takes out is placed the culture dish that mHTF liquid is housed, and the locking pin 12 of usefulness holder 1 is seminiferous tubule one end fixedly, takes the runner 24 of squeezer 2 to push to the other end from nearly holder 1 one ends, and extruding several times repeatedly; At last culture dish is placed under the inverted microscope and observe.
