Ox abomasal displacement operation repositor based on permanent magnetic drive

Technical field

The present invention relates to the technical fields of animal medicine, especially treat the surgical instrument of ox abomasal displacement, specifically Say, refer to the ox abomasal displacement operation repositor based on permanent magnetic drive.

Background technique

Ox left displaced abomasums refer to that the normal anatomy position of abomasum changes, and lead to the internal medicine disease of digestive system function obstacle Disease can be divided into abomasal displacement by the position of left displaced abomasums and abomasum right conjugates, and occur within 1898 true about milk cow earliest Since the report of gastrokateixia, milk cow left displaced abomasums are reported in countries in the world, and disease incidence increases year by year, while bringing great Economic loss, in recent years, with the development of national economy, people increase the demand of milk and dairy produce, China milk cow collection Reduction raising scale expands rapidly, and especially after " melamine " event, free-ranging milk cow fully enters Animal Raising Zone, raising side Formula has changed a lot, and the output of milk of milk cow improves, but due to heredity, kind, disease and feeding and management level backwardness etc. Factors cause the case that left displaced abomasums (especially abomasal displacement) occurs to be increasing, bring to milk cow production Serious economic loss.

Initial stage performance spiritual depressed, loss of appetite when abomasal displacement occurs for milk cow, ruminates reduction, rumen peristalsis sound subtracts Weak, Fecal wastes are reduced, and diarrhea or excrement are in do dilute shape to be alternately present, and body temperature, breathing are normal；As the development of the state of an illness occurs Left side abdominal distension, hydrops, bank nest sink, and appetite abolish ruminates stopping, no rumen peristalsis sound, in clinical diagnosis, in left side 8-13 P&A is carried out at intercostal shoulder joint horizontal line, can hear clear and melodious steel pipe sound；In left side, 9-11 intercostal shoulder joint is water-saving Flat place punctures, it is seen that bronzing puncture fluid, pH value 2.5-4.0, and according to the clinical symptom of milk cow, in conjunction with auscultation, percussion, puncture, Abomasal displacement is generally easy to make a definite diagnosis.

The treatment of abomasal displacement is broadly divided into non-operative treatment and operative treatment, and non-operative treatment is divided into rolling therapy And medicinal treatment, rolling therapy are that left displacement milk cow is led soft fine sand place, fallen right lateral recumbency, is tied respectively Four limbs are tied up, head is protected, its front and back limb is caught, so that it is lain on the back with an angle of 45 ° to the ground, then using backbone as center axis, milk Ox is integrally put to the left, then rapid rolling is sleeping to right side, checks whether abomasum resets after rolling, rolls repeatedly again when not resetting Turn 4-5 times, since this therapy needs manpower too many and high recurrence rate, therefore has clinically been rarely employed, medicinal treatment is to be directed to When pure left displaced abomasums are in view of the factors such as medical expense, postoperative complications and postoperative care, it may be considered that treatment method, Medicinal treatment mainly includes oral purgatives, promotees to ruminate with gastrointestinal motility medicine and antacids etc., promotes gastrointestinal peristalsis, accelerates stomach and intestine row Sky, while alternative intravenous calcium preparation and oral potassium chloride correct electrolyte imbalance, medicinal treatment is in clinical practice not Good result is obtained, a period of time can only be maintained after remission mostly, high recurrence rate generally must finally pass through surgical operation Reduction is carried out, has the medicinal treatment of document report oxygen bromic acid anisodamine and analgin use in conjunction to abomasum occurs in 48h Left displacement case cure rate be 80.2%, right displacement cure rate be 75.0%, but this be only limitted to morbidity early stage just it is timely The case of diagnosis, the combined therapy of Chinese and Western medicine according to another report, Western medicine: 5% Dextrose and Sodium Chloride Inj., compound NaCl injection Prescriptions of traditional Chinese medicine: liquid, vitamin B1 are gavaged together with paraffin oil after the decoctings such as Radix Angelicae Sinensis, the dried immature fruit of citron orange, green peel, dried orange peel, but are not reported Effect after drug therapy.
