Description
Technical field
This utility model belongs to technical field of medical instrument, particularly a kind of New-type radio-frequency scalpel.
Background technology
Radio frequency operation is a kind of fanout free region method of cutting soft tissue, during operation, radio frequency main frame transmitting rf wave is delivered to operative site by scalpel, the cell of contact generates heat because of self-resistance, the heat produced makes the moisture vibration evaporation, decomposition cell in cell, operative site just as by cut like this, achieve the not damaged cutting of tissue, but existing radio frequency scalpel due to its tool temperature be difficult to control, often because tool temperature is too high in operation process, operative site tissues is burnt, burns, cause the Accessory injury of non-treatment object.
Utility model content
Technical assignment of the present utility model provides a kind of New-type radio-frequency scalpel for above the deficiencies in the prior art.
The technical scheme that this utility model adopts is: a kind of New-type radio-frequency scalpel, comprise cutter head, handle of a knife, rf signal reception end, it is characterized in that: described handle of a knife one end is fixedly connected with cutter head, the other end is connected with rf signal reception end by screw thread, cutter head inside is embedded with radio-frequency electrode, cutter head front end is provided with critesistor, radio-frequency electrode and critesistor are connected to rf signal reception end by circuit, handle of a knife is provided with radio frequency starting switch, radio frequency by-pass cock and temperature alarming display lamp, and rf signal reception end is connected with the plug that can be inserted on radio frequency main frame.
This utility model is reasonable in design, and doctor can control radio frequency according to the temperature of patient's operative site and export, and improves the safety of operation.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation;
As shown in the figure: 1, critesistor, 2, cutter head, 3, handle of a knife, 4, radiofrequency signal section, 5, radio frequency starting switch, 6, radio frequency by-pass cock, 7, temperature alarming display lamp, 8, radio-frequency electrode, 9, plug.
Detailed description of the invention
With reference to Figure of description, this utility model is described in detail below:
As shown in Figure 1, a kind of New-type radio-frequency scalpel, comprise cutter head 2, handle of a knife 3, rf signal reception end 4, it is characterized in that: described handle of a knife 3 one end is fixedly connected with cutter head 2, the other end is connected with rf signal reception end 4 by screw thread, cutter head 2 inside is embedded with radio-frequency electrode 8, cutter head 2 front end is provided with critesistor 1, radio-frequency electrode 8 and critesistor 1 are connected to rf signal reception end 4 by circuit, handle of a knife 3 is provided with radio frequency starting switch 5, radio frequency by-pass cock 6 and temperature alarming display lamp 1, and rf signal reception end 4 is connected with the plug 9 that can be inserted on radio frequency main frame.When using this utility model to carry out atraumatic surgical to patient, the connecting pin of rf signal reception end 4 is inserted into the corresponding socket of radio frequency main frame, cutter head 2 inserts diseased region, and the radio frequency starting switch 5 opened on handle 3 can start treatment.When operative site temperature is too high, temperature alarming display lamp 7 can be reported to the police, and doctor can use radio frequency by-pass cock 6, regulates rf frequency, at the end of operation, presses radio-frequency (RF) switch 5.
