Four-dimensional liquid knife

Abstract

The invention discloses a four-dimensional liquid knife. The four-dimensional liquid knife comprises an outer frame, cutter frames, supporting posts, supporting protective plates, elastic bandages, grooves, sliding blocks, chutes, movable discs, target sleeves, pressurized injectors, needle tubes, injection needle heads, handles, tube shell upper covers, threaded pushing rods, injection rubber plugs, rotating shafts and medicament administration holes. The four-dimensional liquid knife has the beneficial effects that four cutter frames are arranged; the cutter frames are all placed in the grooves through the sliding blocks and are connected with the outer frame in a sliding manner so that four-dimensional injection is formed, and the adjustment of the distance between adjacent cutter frames is facilitated; the target sleeves are conical; the target sleeves are connected with the cutter frames in the sliding manner through the movable circular discs; the injection position of the pressurized injectors can be adjusted; the movable ends of the elastic bandages are connected in a detachable manner; the outer frame can be fixed to a lesion joint to be operated through the elastic bandages; and the injection rubber plugs move in the needle tubes through the rotatable connection of the threaded pushing rods and the tube shell upper covers, so that a compound with active macromoleculesis conveniently injected to the lesion joint by medical personnel.

Description

technical field [0001] The invention relates to a liquid knife, in particular to a four-dimensional liquid knife, which belongs to the technical field of medical instruments. Background technique [0002] Liquid knife therapy is a non-surgical treatment method that replaces surgical steel knife by injecting drugs into the joint. And function, evenly distributed on the surface of the diseased synovium, directly play a role in dissolving and metabolizing the diseased synovium, attack the core parts of these diseased synovium, make them lose their activity, and eliminate them from the body through metabolism, thereby eliminating joint swelling and Pain, stop cartilage and bone destruction, prevent joint deformities and organ involvement. [0003] There are certain deficiencies in the existing liquid knife in use. First, the use of various common medical syringes can only inject drugs with low water quality or viscosity. If a macromolecular compound is injected, it will take a ...

AI Technical Summary

Problems solved by technology

[0003] There are certain deficiencies in the existing liquid knife when used. First, the use of various common medical syringes can only inject drugs with low water quality or viscosity. If a macromolecular compound is injected, it will take a lot of effort to complete the filling. Injection, and the injection rate and injection operation stability are difficult to control, thus affecting the injection quality. Second, when in use, the injection position of the liquid knife is prone to deviation, which leads to the poor effect of the injected liquid medicine in the lesion, thereby affecting the therapeutic effect
