Background
An argon-air knife is a treatment that uses an argon plasma beam to conduct high frequency current to inactivate and coagulate tissue by thermal effects. And when in the electrocoagulation mode, a specific plug is used for connecting the high-frequency power source with the argon source, and the focus is subjected to coagulation treatment through the argon spray pipe connected with the argon output end of the argon source. Application of the argon ion electrotome: 1. in the operation of the digestive tract, an argon knife is mostly used for cutting multiple flat polyps with the diameter of 0.1-0.5 cm; 2. can be used for marking the operative dissection range before operation in endoscopic mucosal dissection (ESD) operation; 3. the argon ion electric knife is simple to operate, is relatively safe, has the electric injury depth of about 2mm-3mm, and is generally applied to hemostasis of alimentary tract hemorrhage. The current argon gas nozzle application used in clinic has the following defects: 1. when the argon gas spray pipe is in electrocoagulation, the distance between the spray pipe and the focus is preferably 0.5mm-1mm, and the argon gas spray pipe is too far away from the mucosa to generate electric arc, so that the effect is poor; the spray pipe is too close to the mucosa and is excessively attached, so that argon is conducted to the lower part of the mucosa to cause emphysema under the mucosa, and eschar is easily generated when the spray pipe is directly attached to the mucosa; 2. in clinical operation, the distance between the spray pipe and the focus is not fixed and can be changed along with the respiratory movement frequency of a patient, and particularly for patients with painless operations, the focus fluctuates obviously along with abdominal respiration, so that a good treatment effect is difficult to obtain; 3. argon gas spray tube design is simple, is difficult for controlling operating distance, and the common direct contact mucosa surface in the operation forms eschar very easily on the argon gas spray tube, if the clearance is untimely, can cause the pipeline to block, influences the result of use. 4. The traditional argon gas spray pipe has a thin and soft pipe cavity and is easy to fold.
SUMMERY OF THE UTILITY MODEL
The utility model relates to an overcome not enough among the prior art, provide an argon gas spray tube safety helmet for scope, can the fast control argon gas spray tube with the focus mucosa distance between the wall, reduce the patient because of the influence of abdominal type breathing fluctuation to treatment.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme, an argon gas spray tube safety helmet for scope, including the argon gas spray tube, characterized by: the electric coagulation treatment end of argon gas spray tube has firmly been connect with the safety helmet, the safety helmet shape is cylindrical, and cylindrical safety helmet is equipped with central round hole, the center round hole front end is equipped with the electric coagulation treatment distance round platform of argon gas spray tube and constitutes the stairstepping round hole, center round hole inner wall is equipped with annular arch, the front end surface of safety helmet is equipped with three lug, and the argon gas spray tube is pegged graft with safety helmet center round hole.
The central lines of three convex blocks of the safety helmet form an included angle of 120 degrees, the depth of the convex blocks is 0.5mm-1mm, and the width of the convex blocks is 1.3mm-1.5 mm.
The distance from the distance round platform to the end face of the safety helmet is 1-2 mm.
The height of the annular bulge on the inner wall of the central circular hole is 0.1-0.5 mm.
The side wall of the safety helmet is provided with a liquid-permeable round hole, and the diameter of the round hole is phi 1.5-2 mm.
The central circular hole of the safety cap is in sliding fit with the argon gas spray pipe.
The safety helmet is made of medical plastics.
Has the advantages that: compared with the prior art, the utility model discloses use argon gas spray tube safety helmet, 1 when using argon gas spray tube electric coagulation, can be fast effective the operating distance between accuse argon gas spray tube and the focus mucosa crinkle wall, make it not receive the strong and weak influence of respiratory motion, too far, be difficult for producing electric arc, the effect is poor, too near, excessive laminating mucosa can make the argon gas conduction send the mucosa under, cause the gas swell under the mucosa. The argon spraying pipe safety cap can save operation time and reduce pain of patients. 2. The distance between the spray pipe and the mucosa is effectively controlled, and the phenomenon that the spray pipe is blocked and is difficult to clean due to the fact that eschar is formed by adhering the mucosa when electrocoagulation is performed can be avoided.
