Problems solved by technology
[0003] At present, microwaves are widely used in various gynecological diseases, anorectal diseases, and digestive tract diseases. Treating lesions with various microwave probes can achieve good therapeutic effects. The existing microwave probes have corresponding probe specifications for specific diseases. , it is convenient to replace, but for the probe of the same specification, the electrode cannot be replaced, and the electrode is directly working on the lesion, which is easy to be stained. After the stain, the whole microwave probe is directly replaced, which brings waste, and the microwave probe and the microwave output The conductive stability between the wires becomes poor, which affects the use effect

Embodiment 1
[0028] Such as Figure 1-9 As shown, a replaceable microwave probe includes a connector, and the connector is detachably connected with electrodes.
[0029] The connector includes a shell 6, a conductive joint 9 is fixed inside the shell, and a conductive piece 17 for cooperating with the electrode is installed at the lower end of the conductive joint. Specifically, the connector includes a cylindrical upper section and a tapered lower section, both of which are composed of Made of stainless steel, the outer wall of the upper section is threaded, which is convenient to connect with the microwave output line. The upper section is welded and fixed with a horizontal support plate 8, and the middle position of the support plate is extruded with a downward positioning sleeve 15, which is convenient to manufacture. The interference fit of the coaxial line is equipped with a support sleeve 18, and the epoxy resin adhesive is coated between the positioning sleeve and the support sleev...

The invention relates to a treatment instrument, in particular to a replaceable microwave probe which comprises a connector, the connector is detachably connected with an electrode, the connector comprises a shell, a conductive joint is arranged in the shell, and a conductive sheet used for being matched with the electrode is arranged at the lower end of the conductive joint. A stressing device used for pushing the conducting strip to extrude the electrode is arranged on the connector, a connecting pipe is arranged at the lower end of the shell, the electrode comprises an outer protective pipe, a pole core is arranged in the outer protective pipe in a penetrating mode, the outer protective pipe is in insulation connection with the pole core, the conducting strip is matched with the pole core, and the outer diameter value of the outer protective pipe is the same as that of the connecting pipe. Wherein a connecting column is arranged between the outer protective tube and the connecting tube, the two ends of the connecting column are respectively arranged in the corresponding connecting tube and the outer protective tube in a penetrating manner, a supporting tube is sleeved at the joint of the connecting tube and the outer protective tube, and the supporting tube, the outer protective tube and the connecting tube are extruded, so that the electrode is convenient to replace, and the connecting stability is high.
Description
technical field [0001] The invention relates to a therapeutic instrument, in particular to a microwave therapeutic instrument. Background technique [0002] Microwave probe is a new type of medical device that uses microwave energy to heat parts of the human body to treat various diseases.
