Positioning type anesthetic needle for intraspinal anesthesia

Abstract

The invention discloses a positioning type anesthetic needle for intraspinal anesthesia. The anesthetic needle comprises a sleeving cylinder, a quantitative injection mechanism, an anesthetic needle mechanism and a positioning mechanism. Specifically, two rectangular through holes are symmetrically disposed in the sides of the sleeving cylinder, the quantitative injection mechanism is arranged inthe rectangular through holes, a base is slidably connected to the two rectangular through holes, the base is connected to the internal bottom of the sleeving cylinder through the positioning mechanism, the anesthetic needle mechanism is placed on the base, and a limiting mechanism is arranged on the anesthetic needle mechanism; the quantitative injection mechanism comprises a lantern ring, two connecting blocks are slidably connected to two inner sides of the lantern ring, and the two connecting blocks are respectively in sliding connection with the two rectangular through holes. The positioning type anesthetic needle for intraspinal anesthesia can achieve positioning of a push rod, avoids the situation that the intake dosage cannot be quantified due to uncontrollable strength, prevents certain trouble from being brought to the operation of medical staff, and is convenient for the medical staff to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a positioning anesthesia needle for spinal canal anesthesia. Background technique [0002] From a medical point of view, the meaning of anesthesia is to temporarily lose the patient's overall or local sensation through drugs or other methods, so as to achieve the purpose of painlessness and provide conditions for surgical treatment or other medical examination and treatment. Anesthesia can be roughly divided into general anesthesia and general anesthesia. Two types of local anesthesia, announcement number: CN207012378U discloses an anesthesia needle for anesthesiology department, including a syringe, the syringe includes a cylinder body and a baffle, a needle is fixed on the baffle, and there are connected pinholes on the baffle and the needle. There is a piston for sealing in the cylinder, which also includes a push rod fixed to the piston. There is a drug injection hole...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a positioning anesthesia needle for intraspinal anesthesia, which can locate the position of the push rod and avoid the ingested drug dose due to the inability to control the force during use. Can not be quantified, to prevent certain troubles to the operation of medical staff, easy to use by medical staff, can effectively solve the problems in the background technology
