Abstract

The invention relates to an electric picking and tracting hook for separating small blood vessels under a microscope, which can be used for safely separating and reserving parathyroid glands blood vessels during a surgery, and is provided with a metal hook rod (1). In the invention, an insulation sleeve body (2) is covered on the hook rod; a hook arm (3) is integrally connected to the front end of the hook rod in a bending way; an uncovered joint section (11), which can be connected to a handle of an electrocoagulation scalpel in an insertion way, is arranged on the rear end part of the hook rod; an uncovered transition section (12) is arranged on the front end part of the hook rod; a rotation-stop structure section (21), which is matched with the handle of the electrocoagulation scalpel, is arranged on the rear end part of the insulation sleeve body; the length of the hook rod is 110mm-160mm; the hook arm is in a straight form and has 2.5mm-5.0mm long; a break angle alpha between the hook rod and the hook arm is 115 degrees-135 degrees; the radial dimension of a transition zone from the hook rod to the hook arm is in a gradual change form; and the front end of the hook arm is a blunt circular arc end. The electric picking and tracting hook for separating the small blood vessels under the microscope, provided by the invention, is used for separating and reserving the parathyroid glands blood vessels during the thyroid surgery.

Description

technical field [0001] The present invention relates to thyroid surgery instrument, especially small-incision endoscope or endoscope-assisted thyroid surgery (modified Miccoli endoscope operation mode) (Minimally Invasive Video-assisted Thyroidectomy, MIVAT) operation of separating and retaining parathyroid glands and blood vessels thereof Surgical Instruments. technical background [0002] The parathyroid gland is a human endocrine gland. Its body shape is very small (about 3-8 mm long, 2-5 mm wide, 0.5-2 mm thick, and weighs about 35-50 mg), oblate or oval, with its own capsule and pedicle blood vessels (blood supply arteries and return vein). There are generally two pairs of upper and lower, located on the dorsal side of the left and right thyroid lobes respectively. The parathyroid hormone secreted by the parathyroid gland plays an important role in regulating and maintaining the physiological level of serum calcium. Since serum calcium is the direct source of intrac...
