specific Embodiment 1

[0031] Specific embodiment 1: such as Figure 1-2 As shown, a nerve clipper of the present invention includes: a first clipper 1 and a second clipper 2. The first clipper and the first clipper are hinged to form a nerve clipper; the first clipper and the second clipper The ends of one clip are the ligaments, and the inner sides of the two ligaments are equipped with a micro camera 4, and the micro camera and the ligament form a plane;

[0032] The second scissors handle 2 is provided with a clamping tooth 201 at the shear handle. The clamping tooth is a strip-shaped structure with continuous tooth openings; the first scissors handle is hinged with an adjustment Rod 3, one end of the adjusting rod is hinged with the first shear handle, and the other end is provided with a convex part that can be caught in the tooth mouth.

[0033] The adjusting rod 3 includes a first adjusting rod 301, a first adjusting rod 302, and a rotating sleeve 303. The outer surfaces of the first adjusting r...

specific Embodiment 2

[0034] Specific embodiment 2: A Ni-Fe-based superalloy material, in terms of mass percentage, the superalloy material includes the following alloying elements: C: 0.04-0.05%, Fe: 19.0-21.0%, Cr: 19.5-20.5% , Al: 0.90-1.05%, Ti: 2.65-2.80%, V: 0.20-0.30%, Mo: 2.0-2.5%, Nb: 1.50-1.70%, Y+Ce: 0.046-0.058%, B: 0.003-0.006 %, the balance is Ni and other impurities. Among them, the superalloy material also includes P and S with a mass fraction of less than 0.024%.

[0035] The above-mentioned preparation method of Ni-Fe-based superalloy material includes the following steps:

[0036] 1) Weigh the raw materials according to the percentage of composition, adopt the existing preparation technology of smelting high-temperature alloys, smelt in a vacuum induction furnace at 1500℃, and cast the solution into alloy casting billets;

[0037] 2) Clean the surface of the alloy casting billet, and then heat it to 810-820°C in a vacuum heating furnace and remove the oxide scale on the surface of the...

Abstract

The invention discloses a pair of visual neurological shears comprising a first shear handle and a second shear handle, wherein the first shear handle and the second shear handle are hinged to form the pair of neurological shears. The tail ends of both the first shear handle and the second shear handle are provided with tough portions respectively, micro cameras are disposed on the inner sides ofthe two tough portions, and the micro cameras and the tough portions form a plane. Clamping teeth are disposed at a shear handle position of the second shear handle, the clamping teeth are of a strip-shaped structure, and the strip-shaped structure is provided with a continuous tooth opening. An adjustment rod is hinged to the first shear handle, one end of the adjustment rod is hinged to the first shear handle, and the other end of the adjustment rod is provided with a convex portion capable of being clamped in the tooth opening.

Description

Technical field [0001] The invention relates to the field of medical supplies. Background technique [0002] Neurosurgery (Neurosurgery) is a branch of surgery, which is based on surgery as the main treatment method, applying unique neurosurgery scientific research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and Related affiliated institutions, such as structural damage, inflammation, tumors, malformations, and certain genetic metabolic disorders or dysfunction diseases such as skull, scalp, cerebrovascular and meninges, such as epilepsy, Parkinson's disease, neuralgia and other diseases And pathogenesis, and explore new diagnostic, treatment, and prevention techniques as a high, precise and cutting-edge subject. Neurosurgery is mainly used to treat neurological diseases such as the brain and spinal cord caused by trauma, such as cerebral hemorrhage, which is life-threatening, traumatic brain injury caused by car accid...
