Technical Field

The invention relates to the technical field of animal medicine, in particular to a surgical instrument for treating left abomasum displacement of cattle, and specifically relates to a left abomasum displacement surgical repositor capable of shortening the firing range of a repositioning needle.

Background

Bovine abomasal displacement refers to a medical disease causing digestive system dysfunction due to change of normal anatomical position of the abomasum, which can be divided into abomasal left displacement and abomasal right displacement according to abomasal displacement position, the earliest report on bovine abomasal displacement appears in 1898 years, the bovine abomasal displacement is reported in all countries of the world, the incidence rate is increased year by year, and meanwhile, the significant economic loss is brought, in recent years, along with the development of national economy, the demand of people for milk and milk products is increased, the intensive breeding scale of Chinese dairy cows is rapidly expanded, particularly after a melamine event, all the scattered dairy cows enter a breeding plot, the breeding mode is greatly changed, the milk yield of the dairy cows is improved, but due to a plurality of factors such as heredity, variety, diseases, laggard breeding management level and the like, the cases of abomasal displacement (particularly abomasal displacement) are continuously increased, bringing serious economic loss to the dairy cow breeding industry.

When the cow suffers left abomasal displacement, the early stage of the cow shows depression, appetite reduction, rumination reduction, rumen peristalsis sound attenuation, excrement discharge reduction, diarrhea or excrement alternate in a dry and thin state, and the body temperature and the breath are basically normal; along with the development of the disease, left abdominal distension, effusion, sinking of fossa kanensis, loss of appetite, stopping rumination and no rumen peristalsis sound appear, and during clinical diagnosis, percussion and auscultation are carried out at the horizontal line of 8-13 intercostal shoulder joints on the left side, so that crisp steel pipe sound can be heard; when puncturing at the left 9-11 intercostal shoulder joint level, a reddish brown puncturing solution can be seen, the pH value is 2.5-4.0, and according to the clinical signs of the dairy cows, auscultation, percussion and puncturing are combined, so that the displacement on the left of the true stomach can be easily diagnosed.

The treatment of left displacement of the abomasum mainly comprises non-operative treatment and operative treatment, the non-operative treatment comprises rolling treatment and drug treatment, the rolling treatment is to pull the left displacement cow to a soft fine sand field, lay the cow down on the right side and lay the cow horizontally, bind the four limbs respectively, protect the head, grasp the front and back limbs, lay the cow supine to form an angle of 45 degrees with the ground, then take the backbone as the central axis, place the cow wholly on the left side, quickly roll the cow to the right side to lay, check whether the abomasum is reset after rolling, repeatedly roll the cow for 4-5 times when not resetting, because the treatment needs too much manpower and has high recurrence rate, the drug treatment is rarely used in clinic, the drug treatment is a treatment method which can be considered when the treatment cost, postoperative complications, postoperative care and other factors are considered aiming at the simple abomasum displacement, the drug treatment mainly comprises oral purgative, rumination promoting, gastrointestinal motility and antacid, and the like, promotes gastrointestinal motility, accelerates gastrointestinal emptying, can selectively inject a calcium preparation statically and correct electrolyte imbalance by oral potassium chloride, does not achieve good effect in clinical practice, can be maintained for a period of time after symptom relief, has high recurrence rate, generally needs to be restored by surgical operation at last, has the literature report that the cure rate of the medical therapy combined by anisodamine hydrobromide and analgin on the cases with true-gastric left displacement within 48 hours is 80.2 percent, the cure rate of the right displacement is 75.0 percent, however, the method is only limited to cases diagnosed in time in early onset, and in addition, the reported traditional Chinese and western medicine combination therapy is adopted, and western medicines are: 5% glucose sodium chloride injection, compound sodium chloride injection, vitamin B1, and a traditional Chinese medicine formula: angelica sinensis, immature bitter orange, green tangerine orange peel, dried orange peel and the like are decocted with water and then are infused with paraffin oil for oral administration, but the effect after drug treatment is not reported.
