Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to an injector for closed treatment around an incision.
Background
The concept of an orthopedic painless ward has been widely accepted and publicized in recent years. The pain problem after knee joint replacement surgery is particularly concerned, and the phenomenon that patients have obvious pain after knee joint replacement surgery is obviously reduced compared with the original phenomenon through multi-mode analgesia due to the implementation of the concept of painless ward. In order to reduce the pain after the knee joint replacement, the periphery of the incision is usually subjected to closed treatment in the process of knee joint replacement operation so as to reduce the pain of the postoperative surgical area of the patient, thereby improving the compliance of postoperative functional exercise and improving the functional recovery of the knee joint of the patient. Most of the current commonly used closed therapeutic drugs are anesthetic and glucocorticoid. The knee replacement surgery has a long incision and a large range of closed treatment. At present, when a pain point is clinically treated in a closed mode, a common injector is usually adopted for injection. There is no special syringe for the sealing treatment along the two sides and the periphery of the incision in the knee joint replacement operation, and the common syringe is still used for injecting the sealing medicine point by point at intervals clinically at present. The common injector is used for sealing the periphery of the incision point by point, generally has a vertical single-hole type, is low in injection speed and uneven in distribution, easily causes local muscle agglomeration, is inconvenient to operate and reduces the working efficiency of medical workers due to large pressure and frequent falling of a needle head and a needle cylinder during injection, and has an unsatisfactory anesthesia effect.

In order to achieve the above object, the utility model adopts the following technical scheme: the hand-push type syringe comprises a syringe needle, a needle body, a needle seat, a syringe, a rubber piston, a push rod, a hand-push disc, a liquid distribution hole and a hand ring; one end of the needle body is integrally connected with a needle head, the other end of the needle body is connected with a needle cylinder through a needle seat, a rubber piston is matched in the needle cylinder and connected with a push rod, the end part of the push rod is connected with a hand push disc, a plurality of liquid distribution holes are uniformly distributed in the needle head and the side wall of the needle body, and two symmetrical hand rings are arranged on the outer wall of one end of the needle cylinder; the needle body and the central line of the needle cylinder form an included angle of 30 degrees.
Further, the fluid dispensing apertures are distributed on the side wall of the needle to needle 2/3 length.
Furthermore, the side wall of the needle cylinder is provided with a scale layer.
Further, the bracelet inboard be provided with anti-skidding dogtooth.
Furthermore, the needle seat is screwed with the needle cylinder.
Furthermore, the hand push disc is provided with anti-skid lines.
After the structure is adopted, the utility model discloses the beneficial effect who produces does: a syringe for sealing treatment around incision, convenient to use once seals the injection and can pass through syringe needle multiple spot scattering, enlarges the region of sealing the medicine as far as possible, shortens the injection required time, improves whole effect. Not only can be used for the sealing treatment on a large scale around the incision in the operation, but also can be used for the local anesthesia before the local anesthesia operation, and the utility model has the advantages of simple structure, reasonable setting, low manufacturing cost and the like.
