Abstract
The invention discloses a pen type temperature-controllable heater which can be aseptically packaged, is internally provided with a heating system, can be used for rapid heating of tissue during surgery or for thermotherapy and can also be used for temperature control of shape memory alloy during surgery when the shape memory alloy is used for a human body. The heater can be in direct point contact with the shape memory alloy during surgery so as to enable the alloy to accurately restore to the original shape, surgical operation is benefitted, previous contact of the alloy with wet gauze dipped with hot saline solution is avoided, requirements of the alloy restoring to the original shape are met, proneness to damage to local tissue during surgery is avoided, and local tissue scalding is prevented. The pen type temperature-controllable heater is capable of rapidly conducting heat to local metal by means of point contact with the alloy, so that relevant portions of the alloy rapidly and accurately restore to the original shape, and control is facilitated.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of temperature-controllable pen-type heating device that share with shape memory alloy.
Background technology
Have a wide range of applications aspect Orthopedic medical NiTi shape memory alloy is fixing in Osteological, fracture.In use generally need to regulate temperature, make it when low temperature, to be easy to obtain as required satisfied plastotype, and when high temperature, can recover fast original form, and under the body temperature condition, obtain larger restoring force, so that resetting of fracture obtains firmly to keep.Often need to experience 0-60 ℃ variations in temperature at operating field like this.
Usually control the temperature of NiTi shape memory alloy at clinical middle saline gauze with different temperatures, but the warm saline gauze that uses 60 ℃ carries out the temperature control of shape memory alloy, easily involve surrounding tissue at operating field, if it is not good that repeatable operation or original temperature are regulated, the possibility of scalding surrounding tissue is arranged, and the time one is long, and the temperature of temperature control gauze can return room temperature, so that shape memory alloy plastotype restoring force is not good.
Summary of the invention
The temperature-controllable pen-type heating device that the object of the invention is to overcome the defective of prior art and provide a kind of shape memory alloy to use, this heat-producing machine can be realized accurate temperature controlling.
The object of the present invention is achieved like this:
The temperature-controllable pen-type heating device that a kind of shape memory alloy of the present invention is used, comprise the pen type insulation crust with nib, the pen type jacket with nib section, written section and penholder section, heating rod, heat-conducting medium, heat conduction head and electronic temperature control unit, wherein:
The nib place of described pen type insulation crust has through hole;
Described pen type jacket is located in the pen type insulation crust, and the inwall of the outer wall of described pen type jacket and described pen type insulation crust fits, and the nib section place of described pen type jacket has through hole and this through hole communicates with the nib through hole of described pen type insulation crust;
Described heating rod places in the described pen type jacket, and is positioned at the front end of this pen type jacket penholder section, described heating rod and the electrical connection of described electronic temperature control unit;
