Abstract

The utility model relates to a take temperature control's operation electrotome. It includes electrotome head, electrotome handle and establishes electricity incision pass and the electric switch that congeals on the electrotome handle that inside the electrotome head, be equipped with the contact measurement receptor, the receptor contacts with the electrotome head for monitoring electrotome head temperature in the art, and surely reach the electricity with the electricity and congeal the switch and be connected, the operating circuit constituteed. Temperature -sensing ware, normal atmospheric temperature state are in normally closed state down, when the temperature surpassed the settlement scope, the control by temperature change chip converted the on status into by the normal close, makes the circuit disconnection, the electrotome stop work, and after through natural cooling or physics cooling, the temperature reduces the back, and the electrotome is resumed work. The design is simple, convenient to use to reduce electrotome head temperature, effectual reduction reduces smog and forms the damage of surrounding tissue, reduces the escharosis of electrotome head.

Description

A kind of with temperature controlled electrosurgical

Technical field

This utility model relates to electrosurgical field, is specifically related to the temperature controlled electrosurgical of a kind of band.

Background technology

Current electrosurgical is widely used at medical field, occupies an important position in surgical operating instrument.The operation principle of electric knife utilizes the operation high-tension current produced cut when injected organism tissue and stop blooding, its output is very large, more than 200W can be reached, such as the long-time free of discontinuities operation of bad use habit can cause electric knife head temperature higher, larger spark can be produced during cutting, surroundings thereof's tissue bums can be caused.Electric knife cutting in operation, coagulation muscle and fatty tissue time the smog that produces not only block operator sight line, also can cause medical personnel's headache, the discomfort such as vexed, endanger that it is healthy.Simultaneously in use electric knife head also can produce many eschars, and operator need rub removal on electric knife felt, thus have impact on procedure.

Summary of the invention

In order to overcome the too high injury brought of existing electrosurgical temperature in use, this utility model provides a kind of electrosurgical of the break-off when electric knife head temperature is too high, simplicity of design, easy to use, to reduce electric knife head temperature, effective minimizing, to the damage of surrounding tissue, reduces smog and is formed, and reduces electric knife head eschar and is formed.

In order to reach foregoing invention problem, the utility model proposes following technical scheme: the temperature controlled electrosurgical of a kind of band, it comprises electric knife head, electric knife handle and the TURP switch that is located on electric knife handle and coagulation switch, contact temperature sensor is provided with in electric knife head inside, sensor contacts with electric knife head, for monitoring electric knife head temperature in art, and be connected with TURP and coagulation switch, composition operating circuit.According to electric knife head temperature, sensor is opened or is cut off electric current, for controlling TURP and coagulation function.Described temperature control unit is contact temperature inductor, is in normally off under room temperature state; When temperature exceedes set point, Temperature Controlling Chip is converted to open state by normally closed, and circuit is disconnected, and electric knife quits work, and after by natural cooling or Physical temperature-lowering, after temperature reduces, electric knife is resumed work.

The utility model has the advantages that simplicity of design, easy to use.The beneficial effects of the utility model are, while guarantee work, avoid the unnecessary damage that doctor's faulty operation is brought, be beneficial to the custom that doctor forms proper use of electric knife, only add temperature control element in circuit, structure is simple simultaneously.

Accompanying drawing explanation

Fig. 1 is this utility model vertical section schematic diagram.

Detailed description of the invention

With reference to accompanying drawing, the temperature controlled electrosurgical of a kind of band, it comprises 1. electric knife heads, 2. temperature sensitive member, 3. temperature receptor circuit, 4. TURP button, 5. coagulation button, 6. electric knife handle, 7. working line, 8. working line, 9. working line, 10. high frequency electric input lead.

For further illustrating this utility model, say accompanying drawing to introduce below in conjunction with explanation: when this utility model uses, operated by TURP button and coagulation button when performing the operation, when electric knife head temperature is too high, change with the temperature inductor state of its releasing, block the electric current in circuit, electric knife quits work, thus reduce electric knife head temperature too high bring additional injury, the generation of smog, the formation of eschar, after electric knife head temperature declines, temperature inductor becomes normally off, and electric current connects, and electric knife can work on.

Claims

1. the temperature controlled electrosurgical of band, it comprises electric knife head, electric knife handle and the TURP switch that is located on electric knife handle and coagulation switch, inner at electric knife head, is provided with contact temperature sensor, sensor contacts with electric knife head, for monitoring electric knife head temperature in art, and be connected with TURP and coagulation switch, composition operating circuit, when temperature is too high, sensor cuts off electric current, and TURP switch and coagulation switch quit work, for controlling TURP and coagulation function.

2. one according to claim 1 is with temperature controlled electrosurgical, it is characterized in that to control electric knife duty according to electric knife head temperature control.
