Transligent-patellar operative access to the knee joint of small cattle (sheep)
FIELD: veterinary science.
SUBSTANCE: invention relates to the field of veterinary medicine and is intended for use in operative access to the knee joint of a sheep. Sheep in position on the side is fixed to the operating table. Lower third of the thigh and the upper third of the shin of the sheep's limb, on which the surgical procedure is performed, is cut, the assistant holds it in the bending position. Surgical access zone is treated with an antiseptic. Along its own patellar ligament, starting from its lower corner to the tuberosity of the tibia, an incision of the skin of 3 cm long is performed. Next step is the dissection of subtle subcutaneous fat, providing access to its own patellar ligament. Own patellar ligament is extended all over. Edges of the ligament are separated and fixed. Dissecting part of the fat body, creating a "floating window", with the displacement of which medial condyle is medially visible, and with lateral displacement is the lateral condyle.
EFFECT: method allows for safe operative access to the knee joint for visualization of both hip condyles.

SUBSTANCE: pre-operative fasting venous blood 1 ml is sampled at room temperature 20-24°C into an anticoagulant-free vacuum system (test tube). The test tubes are delivered in a sealed container at temperature 2-8°C for 2 hours to a laboratory for immunoenzyme assay and analysed to determine anti-thyroid stimulating hormone receptor antibodies. If the antibody level is 1.5 units/l or more, a thyroidectomy is performed, whereas the antibody level of less than 1.5 units/l requires performing a subtotal thyroid resection according to standard techniques.
EFFECT: invention enables reducing a probability of recurrent thyrotoxicosis in the patients after subtotal thyroid resection.
SUBSTANCE: group of inventions relates to medicine. A laparoscopic surgical device contains a detachable instrument. The instrument contains an external rod and an internal drive plunger, which can be connected to each other in a detachable or a non-detachable way.

SUBSTANCE: planned skin incision is first configured on an anteriolateral neck surface by projection zoning of a clavisternomastoid and a neck median line to be marked with colour graphic lines. A first line extends along a medial border of the clavisternomastoid. A second line extends from a suprasternal notch to the middle of a hyoid shaft. Both of the lines are then combined by drawing a perpendicular third line from a lower border of the middle of a hyoid shaft to the medial border of the clavisternomastoid, thereby forming a projection triangle. Cutaneofascial layers, platysma and subcutaneous fat are incised along the first and third lines to cut out a musculocutaneous flap, which is brought outwards. Underlying soft tissues are dissected to an anterior surface of cervical spinal bodies by splitting subcutaneous fat between a neurovascular bundle and a pharynx, detaching an intracervical fascia, splitting perioesophageal subcutaneous fat and displacing midline organs of the neck in the medial direction, and the neurovascular bundle - in the lateral direction.
EFFECT: method enables reducing a risk of treatment-induced traumatic injuries of the midline organs of the neck, an upper laryngeal nerve, upper and lower thyroid arteries, as well as a parenchyma and an excretory duct of a submandibular salivary gland with optimising topographo-anatomical relations of the incision wound structures, thus providing a surgical angle approaching 90 degrees.

The muscle is circularly wrapped up with the formed corset.
EFFECT: provision of the sufficient rigidity of the neophallus and elimination of its deformation due to the application of the corset, formed from the mesh with non-absorbable polypropylene monofilaments.

SUBSTANCE: ventral release from a toracotomy approach at an apex is accompanied by excising the seventh, or eighth, or ninth rib to gain an access in the form of an autograft 15-20 cm long. An excised rib autograft is placed into a pocket bed pre-formed from the toracotomy incision in subcutaneous fat and fixed to the subiculum to be used as the autograft; the excised rib autograft is underrun for a period from the moment of the final stage of dorsal correction. The second stage of the surgical treatment is preceded by vertical dry halotraction under the patient's body standing in the space of a therapeutic four-wheel frame equipped with a telescopic arm for the patient's head suspension. At the stage of the dorsal correction, the excised rib autograft is removed through a 2-3-cm incision along the postoperative toracotomy scar from the pocket bed in the subcutaneous fat, cleaned from soft tissues, treated in the antiseptic solution, and placed onto the decorticated posterior elements of the operated spine.
