Technical field
The utility model belongs to medical apparatus technical field, and in particular to a kind of testis biopsy device.
Background technique
Currently, in clinical position, there are two ways to being used for testis biopsy: 1, open surgery open biopsy, Ci Zhongfang
Method needs two people or the above compounding practice of two people, wound relatively large.2, with normal tape needle injection aspiration biopsy, such method
Though wound is smaller, there is following two disadvantage: one, it is less to puncture the testis tissue extracted for single, or even can not extract sometimes
Testis tissue causes repeated multiple times puncture (for diagnostic testicular biopsy, such as to organize less, can only simply assess either with or without essence
Son, but because not extracting more testis tissues, and pathologic finding can not be carried out；For carrying out the trouble of test-tube baby's treatment
Person, if tissue is few, sperm quantity is accordingly less, is not easy to the preferred of sperm), inevitably testicular function is caused to damage.
Two, when carrying out testicular biopsy, fixed testis, another hand need persistently to control syringe, and pull piston to patient on the other hand, with
Just lasting negative pressure is generated, to achieve the purpose that aspirate testis tissue and be extracted, but pull piston can be led repeatedly
Patient's hand fatigue is caused, generation negative pressure is inadequate, even results in puncture needle and deviates from out of testis, causes accidental injury.
Utility model content
The purpose of the utility model is to provide it is a kind of can effectively overcome drawbacks described above, both can be well protected testicular function
Easily operated testis biopsy device again.
For this purpose, the utility model provides a kind of testis biopsy device, the technical solution of the utility model is: a kind of testis
Biopsy device, including syringe, piston, puncture needle and pintle, the puncture needle are fixedly connected by pintle with the nipple of syringe,
