Description

A kind of ox abomasal displacement operation repositor flexible axle assembly

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 a kind of ox abomasal displacement operation repositor flexible axle assembly.

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.Abomasal displacement and the displacement of abomasum right can be divided by the position of left displaced abomasums.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.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 is that left displacement milk cow is led soft fine sand place, and 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 clinically it has 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 Carry out reduction.There is 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.

Since surgical result is certain, the treatment of abomasal displacement is now substantially all to use operative treatment.Mesh Preceding operation method difference essentially consists in the notch difference for opening surgical pathway, mainly has right-hand cutout, right the part between the ribs and the hips portion by ventrimeson to cut The left the part between the ribs and the hips portion notch of mouth, left and right the part between the ribs and the hips portion two incision and omentum majus fixation.Right-hand cutout has an extraordinary hand by ventrimeson The art visual field, is easily peeled off when sticking together, and reduction is fixed to be easy, and when suture needs to do tension suture to fight the larger of abdominal pressure Tension.The milk cow that right the part between the ribs and the hips portion notch is suitble to individual little, when abomasum and histoorgan stick together, operation is more difficult.Left, Right the part between the ribs and the hips portion notch needs attending physician and assistant to complete together, and reduction process is simply easy, but this method wound caused by ox It is larger, influence post-operative recovery.The abomasum for moving to left side can be observed directly using left the part between the ribs and the hips portion notch, to the grainsick that occurs together simultaneously The ox of equal fore stomach diseases is particularly suitable, and left the part between the ribs and the hips portion notch is suitable for omentum majus fixation, the omentum majus fixation of left the part between the ribs and the hips portion notch It is the method for current most veterinary applications.The standard step of the omentum majus fixation treatment of left the part between the ribs and the hips portion notch is as follows:

1. Preoperative Method

Preoperative infected cattle rest half a day；Injection is ruminated in injection, to adjust cud excitement, is promoted digestion, is carried out for successful surgery Prepare；Make arrangements for surgery the equipment such as knife, suture, gauze, haemostatic clamp, tweezers, plastic cement exhaust pipe simultaneously, preparation narcotics, The drug for injection such as thimerosal and glucose salt solution；Preoperative when necessary to give ox fluid infusion, heart tonifying is sent more in cud with stomach catheter Remaining content.

2. surgical procedure

Infected cattle standing restraint, waist side nerve cord conduction anesthesia, cooperates notch local infiltration anesthesia.It is true according to what is diagnosed before Gastrokateixia position determines operative site, after generally in left side, stomach wall picks hair disinfection, the 6- after 30cm, season rib below the transverse process of lumbar vertebra At 8cm, make the vertical incision of a long 15-20cm.

After opening abdominal cavity, from left-hand cutout by hand protrude into it is intraperitoneal detect abomasum, find abomasum, patient checks that abomasum is same Whether there is or not adhesions for peripheral organs tissue, separate at once if any adhesion.It uses if gassy in abomasum and liquid with long length hose Syringe needle punctures abomasum, connects syringe or aspirator, aspirates the gas to stagnate in abomasum and partially liq carries out decompression reduction.

Abomasum is pulled, omentum majus is found, abomasum fixing line wears pastern position i.e. on the omentum majus shallow-layer close to greater curvature, It is about No. 10 bifilar sutures of 1m with curved round needle system, it is preset to make first horizontal button on the omentum majus shallow-layer close to greater curvature Fixing line is sutured, bifilar suture knots on nethike embrane, and line tail is temporarily fixed on wound towel, in first fixing line rear 3-5cm Second horizontal preset suture fixing line of button is remake on the shallow-layer nethike embrane at place, is remake at second fixing line rear 3-5cm The horizontal preset suture of button of third.After three preset fixing lines are worn and fastened, three lines are carried, the order before, during and after Arrangement, and with haemostatic clamp be clamped and fastened on wound towel on it is spare.

Then, patient implements to reset, and pushes down abomasum with palm, through below cud, stomach wall pushes away abomasum to the right, arrives abomasum Up to normal position.Patient's hand exits abdominal cavity, enters abdomen with the line tail that thumb, index finger and middle finger pinch first preset fixing line Chamber, entire arm are detected through entering right side abdominal cavity below cud and determine that fixing line behind the position that right side stomach wall is pierced by, uses hand Refer to the ejection to outside stomach wall in abdominal cavity, assistant is the incision site that can determine on the stomach wall of right side.Assistant carries out right side stomach wall immediately Shaving, cleaning, disinfection and the local infiltration anesthesia of incision, make the skin incision of a 1cm long, small through skin with haemostatic clamp Notch inwardly stabs stomach wall and enters abdominal cavity.At the same time, patient's hand prevents from accidentally injuring internal organ in intraperitoneal protection haemostatic clamp front end. After haemostatic clamp front end enters abdominal cavity, fixing line tail is sent into haemostatic clamp plier by assistant's the first transaction of a day's business haemostatic clamp, patient, and indicates assistant Clamp fixing line, then assistant slowly draws fixing line outside the abdominal cavity of right side.After the same method, second, third root is consolidated Alignment is drawn outside the stomach wall of right side.After abomasum confirms reduction, three fixing lines are pulled to fixed abomasum outward, is until drawing is motionless Only.Bifilar suture at skin incision knots on roll of gauze, after knotting, subtracts line tail, sterilizes to skin incision After sutured.Finally, carrying out the suture of left side incision of abdominal wall, suture layered suture, peritonaeum, musculus trasversus abdomins are continuously sutured, then Oblique, musculus obliquus externus abdominis are successively sutured, finally carries out skin incision tubercle suture again, it is every to have stitched one layer of suture site physiology Salt water rinses, and coating antibiotics prevents the inflammation of art portion from infecting, and keeps wound clean, and extraneous unfavorable factor is avoided to stimulate Wound.

3. postoperative care

Heart tonifying fluid infusion, liver function protecting can be injected intravenously 5% sugar-salt-water 1000-2000ml, add 20% calcium gluconate 3d is used in conjunction 1 time a day in 100ml, VC2g.4,800,000 unit of penicillin, 2,000,000 unit of streptomysin, 2 times a day muscle are used simultaneously Inject anti-infection.In addition, postoperative fasting 1d, next day can give green grass or high-quality digestible green hay, be gradually recovered daily feeding It supports.Finally, postoperative wound winter pays attention to antifreeze, hot day pays attention to anti-maggot.

However, the omentum majus fixation of the left the part between the ribs and the hips portion notch of standard has its shortcoming during operation.

1, due to being two sides stomach wall notch simultaneously, wound is more, and, easy infection big to tissue damage, Wound healing speed is slow, right Infected cattle is a kind of greatly burden.

2, patient is in hand-held needlework when intraperitoneal stomach wall to the right is mobile, if ox moves or shakes suddenly, patient is careless Needle is fallen in the internal organ in ox abdomen or piercing through ox, ox can be caused huge harm.

3, the physique of some oxen is very big, and when practical operation is performed the operation, patient takes off light jacket, and entire arm all puts in ox abdomen In, right side stomach wall target position cannot be still touched, the selection right side stomach wall position on the lower side that can only have to take the second best is fixed, thus Lead to left displacement recurrence.
