Description
Technical field
The present invention relates to the technical field of animal medicine, especially treating the operating theater instruments of cattle abomasal displacement, specifically, is a kind of magnetic strength acoustic control locate mode cattle abomasal displacement positor.
Background technology
Cattle left displaced abomasums refers to that the normal anatomy position of abomasum changes, and causes the internal disease of digestive system function obstacle.Abomasal displacement and the displacement of abomasum right can be divided into by the position of left displaced abomasums.Since within 1898, there is the report the earliest about milch cow left displaced abomasums, milch cow left displaced abomasums is in the news in countries in the world, and sickness rate increases year by year, brings great economic loss simultaneously.In recent years, along with the development of national economy, people increase the demand of cattle Milk and milk products, China's milch cow intensive farm scale expands rapidly, particularly after " tripolycyanamide " event, raise milch cow scattered and all enter Animal Raising Zone, feeding manner has a very large change, the milk yield of milch cow improves, but due to factors such as heredity, kind, disease and feeding and management level backwardnesss, cause the case that left displaced abomasums (particularly abomasal displacement) occurs to be on the increase, bring serious economic loss to milk cow production.
During milch cow generation abomasal displacement, initial stage performance spirit is depressed, and appetite declines, and ruminate minimizing, rumen peristalsis sound weakens, and Fecal wastes reduces, and diarrhoea or feces alternately occur in dry rare shape, body temperature, breathe normal; There is left side abdominal distention in the development along with the state of an illness, hydrops, and bank nest sink, and appetite is absolutely useless, ruminates stopping, without rumen peristalsis sound.When clinical diagnosis, in left side, 8-13 intercostal shoulder joint horizontal line place carries out P&A, can hear clear and melodious steel pipe sound; In the puncture of 9-11 intercostal shoulder joint level place, left side, visible red brown puncture fluid, pH value 2.5-4.0.According to the clinical symptom of milch cow, in conjunction with auscultation, percussion, puncture, abomasal displacement is generally easy to make a definite diagnosis.
The treatment of abomasal displacement is mainly divided into non-operative treatment and operative therapy, and non-operative treatment is divided into rolling therapy and pharmacotherapy.Rolling therapy left is conjugated milch cow to lead soft fine sand place; fallen right lateral recumbency; bundle extremity respectively, protect head, catch limb before and after it; make its angle at 45 ° with ground of lying on the back; then axle centered by spinal column, is sidelong milch cow entirety left, then rolling is sleeping to right side rapidly; check after rolling whether abomasum resets, rolling 4-5 time repeatedly again when not resetting.Because this therapy needs manpower too many and relapse rate is high, therefore seldom use clinically.Pharmacotherapy is when considering the factors such as medical expense, post-operative complication and postoperative care for pure left displaced abomasums, admissible Therapeutic Method.Pharmacotherapy mainly comprises oral cathartic, urgees to ruminate and gastrointestinal motility medicine and antacid etc., promotes gastrointestinal peristalsis, accelerates gastrointestinal emptying, and alternative quiet note calcium preparation and oral potassium chloride correct electrolyte imbalance simultaneously.Pharmacotherapy does not obtain good result in clinical practice, and mostly can only maintain a period of time after remission, relapse rate is high, generally finally must carry out reduction by surgical operation.Have the pharmacotherapy of bibliographical information oxygen bromic acid Anisodamine and dipyrone use in conjunction to be 80.2% to the case cure rate that abomasal displacement occurs in 48h, the cure rate of right displacement is 75.0%, but this is only limitted to the early stage case with regard to diagnosis in time of falling ill.Separately there is the combined therapy of Chinese and Western medicine of report, Western medicine: 5% Dextrose and Sodium Chloride Inj., compound sodium chloride injection, vitamin B
1, prescriptions of Chinese medicine: gavage together with paraffin oil after the decoctings such as Radix Angelicae Sinensis, Fructus Aurantii Immaturus, Pericarpium Citri Reticulatae Viride, Pericarpium Citri Reticulatae, but do not report the effect after Drug therapy.
Because surgical result is certain, the treatment of abomasal displacement all adopts operative therapy now substantially.Current operation method difference is mainly that the otch opening surgical pathway is different, mainly contains the left the part between the ribs and the hips portion otch of ventrimeson other right-hand cutout, right the part between the ribs and the hips portion otch, left and right the part between the ribs and the hips portion two incision and omentum majus fixation.The other right-hand cutout of ventrimeson has an extraordinary surgical field of view, and easily peel off when sticking together, reduction is easily fixing, needs to do tension suture to resist the comparatively hightension of abdominal pressure during stitching.Right the part between the ribs and the hips portion otch is applicable to individual little milch cow, comparatively difficulty of performing the operation when abomasum and histoorgan stick together.Left and right the part between the ribs and the hips portion otch needs the doctor in charge to complete together with assistant, and reduction process is simply easy, but the wound that this method causes cattle is comparatively large, affects post-operative recovery.Apply left the part between the ribs and the hips portion otch and can observe directly the abomasum moving to left side, the Niu Youwei of the fore stomach disease such as grainsick that simultaneously occur together is applicable to, left the part between the ribs and the hips portion otch is suitable for omentum majus fixation, and the omentum majus fixation of left the part between the ribs and the hips portion otch is also the method for current most veterinary's application.The standard step of the omentum majus fixation treatment of left the part between the ribs and the hips portion otch is as follows:
1. Preoperative Method
Preoperative sick cattle rest half a day; Injection is ruminated in injection, and to regulate cud excited, facilitating digestion, for successful surgery is ready; Make arrangements for surgery the equipment such as cutter, suture, gauze, mosquito forceps, tweezers, plastic cement exhaustor simultaneously, the drug for injection such as preparation narcotics, disinfectant solution and D/S; Preoperatively if desired will give cattle fluid infusion, heart tonifying, sends content unnecessary in cud with stomach catheter.
2. operation process
Sick cattle standing restraint, the other nerve trunk conduction block of waist, coordinates otch local infiltration anesthesia.Operative site is determined in left displaced abomasums position according to diagnosing before, generally after left side stomach wall picks hair sterilization, and 6-8cm place after 30cm, season rib below transverse process of lumbar vertebra, the vertical incision of work one long 15-20cm.
After opening abdominal cavity, from left-hand cutout, hands is stretched into intraperitoneal and detect abomasum, find abomasum, patient checks abomasum with peripheral organs tissue with or without adhesion, is separated at once if any adhesion.If gassy in abomasum and liquid are then with the syringe needle puncture abomasum with long length hose, connect syringe or suction pump, in suction abomasum, stagnant gas and partially liq carry out decompression reduction.
