Abstract

A novel sheep uterus cornu inseminating syringe belongs to animal husbandry and veterinary equipment. A rack vertically and movably mounted in a casing is rotatably mounted on the casing, a gear is meshed with the rack, a rod sleeve is mounted at the lower end of the casing, a push rod is vertically movably inserted into the rod sleeve, the upper end of the push rod is connected with the lower end of the rack, a piston is detachably mounted at the lower end of the push rod and matched with the wall of the inner hole of the rod sleeve in a sealed manner, a needle is detachably fitted to the lower end of the rod sleeve, and a double-lobe elastic clamp type uterus cornu fixing sleeve is arranged outside the rod sleeve. The novel sheep uterus cornu inseminating syringe can be used for semen deposition with a test tube, can also be used for semen disposition with a thin tube, and has the advantages of simple structure, wide application, fine semen deposition quality and high operating efficiency.

Description

A kind of novel sheep cornua uteri seme-deposition device

Technical field

The invention belongs to the animal and veterinary apparatus, relates generally to the sheep uterus semen deposition utensil that uses among a kind of artificial fertilization technology.

Background technology

Used intraperitoneal spermatic gun mainly comprises two kinds at present, is simple function, can not dual-purpose.First kind, bright frozen semen smart or that freeze in the fine tube need be transferred in the test tube, and then it is transferred to semen deposition in the spermatic gun, can not directly use at freezing fine tube.Because the frozen semen vigor that freezes in the fine tube is very low, easily causes motility of sperm further to descend in the transfer process, and operation inconvenience; Second kind, will freeze fine tube and directly pack in the spermatic gun, export seminal fluid then, can not directly use at the seminal fluid in the test tube.Bright essence in the test tube also needs to pack in advance to freeze in the fine tube and just can finish semen deposition, operation inconvenience.More than two kinds of intraperitoneal spermatic guns all can not satisfy the semen deposition operation requirement of test tube neutralization freezing seminal fluid in the fine tube simultaneously, and do not have the cornua uteri fixture, be prone to cornua uteri during semen deposition and slide, operation inconvenience.Be badly in need of at present a kind of cornua uteri semen deposition operation requirement that can satisfy test tube neutralization freezing seminal fluid in the fine tube simultaneously, and novel spermatic gun with cornua uteri fixture, so as to realize the sheep seminal fluid quick and easy be input to assigned address.

Summary of the invention

The purpose of the invention is exactly the problem that exists at above-mentioned prior art, actual needs in conjunction with market, design provides a kind of novel sheep cornua uteri seme-deposition device, reaches that applied widely, adaptive capacity is strong, the semen deposition quality is good, the purpose of semen deposition efficient height, operation simple and convenient.

The purpose of the invention is achieved in that in housing can be equipped with tooth bar up or down, and gear is installed in rotation on the housing, the wheel and rack engagement; Mounting rod cover on the housing bottom, fluid push rod can be inserted in the bar cover up or down, and the fluid push rod upper end is connected with the tooth bar lower end; Piston is removably mounted on the fluid push rod bottom, and contacts cooperation with the face seal of bar cover inner hole wall; Removably equipped syringe needle on bar cover bottom; At bar cover exterior arrangement bivalve elasticity folder formula cornua uteri fixed cover, so far constitute a kind of novel sheep cornua uteri seme-deposition device.

The invention both can be used for seminal fluid semen deposition use in the test tube, and the semen deposition that can be used for straw semen is again used, and has characteristics simple in structure, easy to use, applied widely, that the semen deposition quality is good, working performance is high.

The specific embodiment

Below in conjunction with accompanying drawing the invention embodiment is described in detail.A kind of novel sheep cornua uteri seme-deposition device can be equipped with tooth bar 3 up or down in housing 1, gear 2 is installed in rotation on the housing 1, gear 2 and tooth bar 3 engagements; Mounting rod cover 4 on housing 1 bottom, fluid push rod 6 can be inserted in the bar cover 4 up or down, and fluid push rod 6 upper ends are connected with tooth bar 3 lower ends; Piston 7 is removably mounted on fluid push rod 6 bottoms, and overlaps 4 inner hole wall face seals with bar and contact cooperation; Overlap removably equipped syringe needle 8 on 4 bottoms at bar; Overlap 4 exterior arrangement bivalve elasticity folder formula cornua uteri fixed cover 5 at bar.

When semen deposition liquid uses: 1, in the test tube during seminal fluid semen deposition, can at this seme-deposition device fluid push rod 6 head ends piston 7 be installed earlier, the gear 2 that turns clockwise then drives tooth bar 3, seminal fluid is drawn to the seme-deposition device bar to be overlapped in 4 chambeies, bivalve elasticity under natural closure state folder formula cornua uteri fixed cover 5 is imported the ewe abdominal cavity from operative incision, cornua uteri is fixed, from cornua uteri fixed cover cavity, import the seme-deposition device main body then, seme-deposition device syringe needle 8 thrusts in the sheep cornua uteri, turn gear 2 is injected into seminal fluid in the cornua uteri counterclockwise.2, in the tubule during seminal fluid semen deposition, disassemble piston 7, directly tubule is encased in the bar cover 4, cornua uteri fixed cover 5 under the natural closure state is imported the ewe abdominal cavity from operative incision, cornua uteri is fixed, from cornua uteri fixed cover 5 cavities, import the seme-deposition device main body then, seme-deposition device syringe needle 8 thrusts in the sheep cornua uteri, turn gear 2 utilizes this seme-deposition device fluid push rod 6 to promote the tubule tampon counterclockwise, and seminal fluid is injected in the cornua uteri.The detachable syringe needle 8 of installing, with make things convenient for tubule in bar cover 4 installation and with then taking off operation from fluid push rod 6.
