Abstract

The invention discloses a device for efficiently scraping and smashing the convoluted seminiferous tubule to obtain sperms. The device comprises scraping and smashing needles, a fixing needle sleeve, a handheld handle and a scraping and smashing needle sleeve. The fixing needle sleeve is arranged at one end of the handheld handle in a long bar shape. The fixing needle sleeve is fixed to the handheld handle in a sleeving mode. The multiple comb-shaped scraping and smashing needles are fixedly installed on the top face of the fixing needle sleeve (2). The scraping and smashing needles are arranged in the scraping and smashing needle sleeve in a sleeved mode and clamped to the fixing needle sleeve. The device is simple in structure, convenient to operate and capable of effectively shortening time for smashing the convoluted seminiferous tubule to obtain the sperms; moreover, the smashing degree is high, the sperms in the convoluted seminiferous tubule can be obtained to the maximum degree, the larger fertility rate is brought to patients, and the device is suitable for being widely applied and popularized.

Description

technical field [0001] The invention relates to a scraper for fertile tubules in human assisted reproductive technology, in particular to a device for efficiently scraping and crushing fertile tubules to obtain sperm. Background technique [0002] At present, in the human assisted reproductive technology, the successful clinical application of intracytoplasmic sperm injection (ICSI) has brought good news to many patients with male infertility. Testicular biopsy is often required in patients with non-obstructive azoospermia or in patients with failed sperm retrieval on the day of oocyte retrieval. Therefore, whether sperm can be obtained from the seminiferous tubules is the key to whether these patients can have children with assisted reproductive technology. At present, the common methods for obtaining sperm from the seminiferous tubules include cutting with ophthalmic scissors or scraping with a 1ml syringe. However, these methods fail to completely scrape the seminiferou...
