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, particularly relate to a kind of temperature-controllable pen-type heating device share with shape memory alloy.
Background technology
Orthopedic medical NiTi shape memory alloy has a wide range of applications in Osteological, Fracture internal fixaiion.In use generally need to regulate temperature, make it to be easy to when low temperature obtain satisfied plastotype as required, and original form can be recovered when high temperature fast, and under body temperature, obtain larger restoring force, the reset of fracturing is obtained and firmly maintains.The variations in temperature experiencing 0-60 DEG C is often needed like this at operating field.
Usually the temperature of NiTi shape memory alloy is controlled at the saline gauze of clinical middle use different temperatures, but use the warm saline gauze of 60 DEG C to carry out the temperature control of shape memory alloy, easily surrounding tissue is involved at operating field, if repeatable operation or original temperature regulate not good, there is the possibility of scalding surrounding tissue, and the time one is long, the temperature of temperature control gauze can return room temperature, makes shape memory alloy plastotype restoring force not good.
Summary of the invention
The object of the invention is to overcome the defect of prior art and provide a kind of temperature-controllable pen-type heating device of shape memory alloy, this heat-producing machine can realize accurate temperature controlling.
The object of the present invention is achieved like this:
