Cow true stomach left deflection operation reset device of double-locking structure

Abstract

The invention discloses a cow true stomach left deflection operation reset device of a double-locking structure. The cow true stomach left deflection operation reset device comprises a fixing thread with one end fixedly connected with the cow true stomach omentum majus. The operation reset device further comprises an annular magnet, a fixing magnet and a clamping device, wherein the fixing magnet is fixed to the outer side of the right cow abdomen and matched with the annular magnet, and the clamping device is used for clamping the annular magnet. A trapezoid hole penetrating into the outer ring side of the annular magnet from the inner ring side of the annular magnet is formed in the annular magnet, the fixing thread is provided with a knot, the diameter of the knot is larger than the aperture of the narrow part of the trapezoid hole but smaller than the aperture of the wide part of the trapezoid hole, the wide part of the trapezoid hole is provided with a thread clamping groove matched with a thread clamping device, and the thread clamping device is provided with a clamping strip and a clamping block, wherein the fixing thread can be pressed into the thread clamping groove through the clamping strip, and the clamping block can extend into the wide part of the trapezoid hole to be matched with the knot in a clamping mode. The annular magnet is internally provided with a blade capable of cutting off the fixing thread on the narrow part of the trapezoid hole. The cow true stomach left deflection operation reset device has the advantages that the right side of the cow abdomen does not need to be incised or threaded with a needle, the trauma of a cow from the operation is greatly reduced, and the left deflection relapsing of the cow true stomach is eradicated.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a surgical instrument for treating the left displacement of the bovine abomasum, specifically, a double locking structure surgical reset device for the left displacement of the bovine abomasum. Background technique [0002] Cattle abomasum displacement refers to an internal medical disease in which the normal anatomical position of the abomasum changes, leading to digestive system dysfunction. According to the position of abomasum displacement, it can be divided into left abomasum displacement and abomasum right displacement. Since the first report of cow abomasum dislocation appeared in 1898, cow abomasum dislocation has been reported all over the world. In recent years, with the development of the national economy, people's demand for milk and dairy products has increased, and the scale of intensive dairy cow breeding in my country has expanded rapidly. Especially ...

AI Technical Summary

Problems solved by technology

The existing technology still has the following deficiencies: first, the fixed line of the right abdominal wall wound directly runs through the entire right abdominal wall including the peritoneum, muscle, and skin, and the peristalsis of the abomasum drives the fixed line to move. It is easy to be infected and suppurated, and in severe cases, the infection may even develop into the abdominal cavity; second, after the fixation line is removed, the abomasum will be free again, and the left displacement of the abomasum is likely to recur (for example, after another childbirth); third, in the In clinical practice, even if the right fixation line is not removed at the risk of infection, the fixation line will be broken due to wear and tear, and the risk of recurrence of left abomasum displacement cannot be avoided
