Abstract
The utility model relates to a novel surgical small needle knife, which comprises a knife edge, drug injection holes, a knife arm, a drug injection cavity, a heparin cap, a gas valve and a handle, wherein the knife edge, the knife arm and the handle are connected into a whole; the knife edge is formed at the front end of the novel surgical small needle knife and is provided with the drug injection holes; the knife arm and the handle are arranged at the rear part of the knife edge in sequence; the drug injection cavity is formed in the knife arm, and a drug injection pipe is arranged below the rear end of the knife arm and is communicated with the drug injection cavity; the heparin cap is arranged on the drug injection pipe; and the gas valve is arranged above the rear end of the knife arm, and gas vents of the gas valve are communicated with the drug injection cavity as well. When in use, a scalp acupuncture of a syringe pierces into the heparin to inject liquid pain killer into the drug injection cavity, and the gas valve is opened. At the moment, while the small needle knife conducts cutting and debonding, the liquid pain killer in the drug injection cavity is ceaselessly released to the surgical site via the drug injection holes, thereby achieving good analgesic effect. The utility model has reasonable design and remarkable continuity and analgesia of the surgery, thereby relieving the pain of patients.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically is the novel operation small needle knife.
Background technology
In clinical, treatment stuck-finger, soft tissue adhesion, the beam bending adhesion of hip shin and de Quervain's disease need closed or cutting treatment, the first-selection of small needle knife operation becoming treatment, its energy alleviating pain, restore funcitons, evident in efficacy, wound is little, has no side effect, form by blade, tool arm, handle three parts but the small needle knife that uses is many at present, simple in structure, function singleness is when particularly performing an operation to the bigger patient of extent of disease, need perform an operation while injecting analgesic, interrupted the seriality of operation, prolonged the time of operation, increased misery to the patient.
Summary of the invention
This utility model overcomes the deficiency that above-mentioned technology exists, and a kind of novel operation small needle knife that can inject analgesic in operation process simultaneously is provided.
The technical solution of the utility model is: the novel operation small needle knife, be made up of blade, medicine-pouring hole, tool arm, medicine-injecting cavity, calparine cap, air valve, handle, wherein, blade, tool arm, handle join together, blade is positioned at the front end of novel operation small needle knife, is distributed with a plurality of medicine-pouring holes on the blade; The blade rear portion is tool arm, hands handle successively; The inside of tool arm is provided with medicine-injecting cavity, and the below of tool arm rear end is provided with medicine-pouring pipe, and medicine-pouring pipe communicates with medicine-injecting cavity, establishes calparine cap on the medicine-pouring pipe; The top of tool arm rear end is provided with air valve, and the pore of air valve also communicates with medicine-injecting cavity.
When this utility model uses, thrust heparin with the syringe nozzle sword-shaped needle, antalgica liquid is injected in the medicine-injecting cavity, open air valve, small needle knife is when cutting, loosening at this moment, and the antalgica liquid in the medicine-injecting cavity ceaselessly discharges to operative site by medicine-pouring hole, need not stop operation for extent of disease because of injecting analgesic than major operation, shorten operating time, reduced patient's misery.
This utility model is reasonable in design, and the seriality of operation and analgesia property are remarkable, to the contracture of tissue loosen, the significant curative effect of having loosened of de Quervain's disease and myofascitis,
