Description

A New Sheep Uterine Horn Inseminator

technical field

The invention belongs to animal husbandry and veterinary equipment, and mainly relates to a sheep uterus insemination equipment used in artificial insemination technology.

Background technique

Currently used intraperitoneal insemination guns mainly include two types, both of which have a single function and cannot be used concurrently. The first one needs to transfer fresh semen or frozen semen in a frozen fine tube to a test tube, and then transfer it to an insemination gun for insemination, which cannot be used directly for frozen fine tubes. Since the motility of the frozen semen in the frozen fine tube is already very low, the sperm motility is likely to further decrease during the transfer process, and the operation is inconvenient; the second method is to directly put the frozen fine tube into the insemination gun, and then output the semen, which cannot be directly For use with semen in test tubes. The fresh semen in the test tube also needs to be put into the frozen fine tube in advance to complete the insemination, which is inconvenient to operate. Both of the above two intraperitoneal insemination guns cannot meet the insemination operation requirements of semen in test tubes and frozen seminiferous tubes at the same time, and there is no uterine horn fixing device, and the uterine horns are prone to slide during insemination, which is inconvenient to operate. At present, there is an urgent need for a new type of insemination gun that can meet the operation requirements of uterine horn insemination of semen in test tubes and frozen semen tubes, and has a uterine horn fixation device, so as to realize fast and convenient input of sheep semen to designated positions.

Contents of the invention

The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and combine the actual needs of the market to design and provide a new type of sheep uterine horn insemination device, which has wide application range, strong adaptability, good insemination quality and high insemination efficiency. High, easy and convenient operation.

The purpose of the present invention is achieved in the following way: a rack is equipped to move up and down in the housing, the gear is rotatably mounted on the housing, and the gear and the rack are meshed; a rod sleeve is installed on the lower end of the housing to push the liquid The rod can be moved up and down and inserted into the rod sleeve, the upper end of the push rod is connected with the lower end of the rack; The needle head is detachably equipped on the head; the double-lobe elastic clip type uterine horn fixing sleeve is arranged on the outside of the rod sleeve, so far a new type of sheep uterine horn insemination device is formed.

The invention can be used not only for the insemination of semen in test tubes, but also for the insemination of semen in thin tubes, and has the characteristics of simple structure, convenient use, wide application range, good insemination quality and high operating efficiency.

Detailed ways

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A new type of sheep uterine horn insemination device, in which a rack 3 can be moved up and down in the housing 1, and the gear 2 is rotatably installed on the housing 1, and the gear 2 is meshed with the rack 3; at the lower end of the housing 1 Rod sleeve 4 is installed on the upper part, and the liquid pushing rod 6 can be inserted into the rod sleeve 4 to move up and down, and the upper end of the liquid pushing rod 6 is connected with the lower end of the rack 3; the piston 7 is detachably installed on the lower end of the liquid pushing rod 6, And it is in sealing contact with the wall surface of the inner hole of the rod sleeve 4; the needle head 8 is detachably equipped on the lower end of the rod sleeve 4;

When using semen infusion: 1. For the insemination of semen in the test tube, first install the piston 7 at the head end of the push rod 6 of the insemination device, and then rotate the gear 2 clockwise to drive the rack 3 to suck the semen into the insemination device In the rod sleeve 4 cavity, the double-flap elastic clip type uterine horn fixing sleeve 5 in the naturally closed state is introduced into the abdominal cavity of the ewe from the surgical incision, the uterine horn is fixed, and then introduced into the main body of the insemination device from the hollow cavity of the uterine horn fixing sleeve , the needle 8 of the insemination device penetrates into the uterine horn of the sheep, and the gear 2 is rotated counterclockwise to inject the semen into the uterine horn. 2. For the insemination of semen in the thin tube, disassemble the piston 7, directly put the thin tube into the rod sleeve 4, insert the uterine horn fixing sleeve 5 in the naturally closed state into the abdominal cavity of the ewe from the surgical incision, and insert the uterus The horn is fixed, and then the main body of the insemination device is introduced from the hollow cavity of the uterine horn fixing sleeve 5, the needle 8 of the insemination device penetrates into the sheep's uterine horn, the gear 2 is rotated counterclockwise, and the thin tube is pushed by the liquid pushing rod 6 of the insemination device A tampon to inject semen into the uterine horns. The needle head 8 can be detachably installed to facilitate the installation of the thin tube in the rod sleeve 4 and the operation of removing it from the liquid pushing rod 6 after use.
