Referring to fig. 1 to 4, a schematic structural diagram of a portable temperature-controlled surgical electric coagulation pen according to the present utility model is shown. The portable temperature control type surgical electric coagulation pen provided by the utility model comprises a pen container 10, a rotating head 20, a power supply 30, a switch assembly 40, a temperature control module 50 and a cutter head assembly 60. The rotating head 20 is rotatably connected with the front end of the pen container 10, and a nut 11 is arranged at the bottom end of the pen container 10. The power supply 30, the switch assembly 40, the temperature control module 50 and the cutter head assembly 60 are located in the barrel 10. One end of the power supply 30 is electrically connected to one end of the switch assembly 40, the other end of the power supply 30 is electrically connected to one end of the temperature control module 50, and the other end of the switch assembly 40 is electrically connected to one terminal of the tool bit assembly 60. The other end of the temperature control module 50 is electrically connected to the other terminal of the tool bit assembly 60. In this embodiment, the power source is a 2PCS battery and the rotator head 20 is a plastic sleeve.
The temperature control module 50 includes a temperature sensing assembly 51 and a temperature control assembly 52, and the tool bit assembly 60 includes a heating wire 61, where the heating wire 61 protrudes from the rotating head 20. The temperature sensing component 51 is configured to sense a temperature signal of the heating wire 61 and send the temperature signal to the temperature control component 52, and the temperature control component 52 is configured to selectively control on/off of the heating wire 61 according to the temperature signal. The electrocoagulation pen is further provided with a protective cover 70 which can be covered on the rotating head 20 to protect the heating wire 61. The temperature control assembly 52 may be a single-chip microcomputer.
The bit assembly 60 also includes a copper needle fastener 62 and two copper needles 63. Two copper needles 63 are respectively connected with two ends of the heating wire 61 and are fixed on the copper needle fastening piece 62, and the two copper needles 63 are two wiring terminals of the cutter head assembly 60. The temperature sensing assembly 51 is in contact with the copper needle 63. When the two terminals are connected with the positive electrode and the negative electrode of the power supply 30, the heating wire 61 heats, and the heat is transmitted to the temperature sensing assembly 51 through the two copper pins 63, so that a temperature signal is generated and fed back to the temperature control assembly 52.
The tool bit assembly 60 further comprises two connecting handles, two ends of the heating wire 61 are respectively detachably connected with the two connecting handles, and the copper needle 63 is connected with the end part of the heating wire 61 through the connecting handles; the heating wire 61 is formed as a flat cutter head or a sharp cutter head; and/or the heating wire 61 has a sheet-like blade; and/or, the two connecting handles are bent into a gun stock shape.
The temperature signals include a first temperature signal and a second temperature signal, and the temperature control assembly 52 is configured to energize the heater 61 when the first temperature signal is received and to de-energize the heater 61 when the second temperature signal is received. The first temperature signal corresponds to a first temperature value of the heating wire 61, and the second temperature signal corresponds to a second temperature value of the heating wire 61, which is greater than the first temperature value. The first temperature value is a lower temperature limit value for the normal operation of the heating wire 61, and the second temperature value is an upper temperature limit value for the normal operation of the heating wire 61. The temperature control assembly 52 also includes a time delay switch unit. The temperature sensing assembly 51 includes a thermistor, which may also be an integrated module capable of measuring temperature, without limitation. The temperature control component 52 may be a common control device such as a single chip microcomputer, and the temperature control component 52 is further configured to trigger the delay switch unit and delay the power off of the heating wire by the delay switch unit for a predetermined time when the second temperature signal is received for the first time after the electric coagulation pen is powered on. The delay switch unit may be a conventional delay switch circuit or a delay switch module, which is not limited herein.
For example, after the switch moving plate 41 is in contact with the switch fixed ring 42 and is powered on, when the temperature control component 52 receives the second temperature signal sensed by the temperature sensing component 51, the delay time of the delay switch unit is triggered to start, and when the working time of the delay switch unit reaches a set time length, the delay switch unit is powered off to stop supplying power to the heating wire 61. The temperature of the heating wire 61 is a temperature interval in which the temperature of the heating wire 61 is kept constant by the temperature control assembly 52 during the prolonged period of time, and when the temperature of the heating wire 61 reaches the second temperature value, the temperature control assembly 52 stops the power supply of the heating wire 61 to start to decrease the temperature. When the temperature of the heating wire 61 is reduced to the first temperature value, the temperature control assembly 52 resumes the power supply to the heating wire 61, and continuously repeats the above cyclic power supply until the time delay switch unit reaches the set time length, and then stops the power supply to the heating wire 61. The heating temperature of the heating wire 61 can be in a certain set temperature range by the working mode, so that the damage caused by long-time electrifying of the heating wire 61 and carbonization of skin and meat tissues at the patient can be prevented, and the smooth operation can be ensured.
The upper and lower temperature limits and the extended operating time of the delay switch unit may be set according to actual conditions, and are not limited herein. It will be appreciated that in normal operation, when the temperature of the heating wire 61 is below the lower temperature limit, the temperature control assembly 52 resumes energizing the heating wire 61; the temperature control assembly 52 stops supplying power to the heating wire 61 whenever the temperature of the heating wire 61 reaches the upper temperature limit. The temperature control is achieved by circulation.
The switch assembly 40 includes a switch moving plate 41, a switch fixed ring 42, and a switch button 43; the switch moving plate 41 has elasticity, one end of the switch moving plate 41 is electrically connected with the positive electrode of the power supply 30, the other end of the switch moving plate 41 selectively contacts the switch fixing ring 42, and the switch fixing ring is a copper ring.

The switch fixing ring 42 is electrically connected to one of the copper pins 63, and the other copper pin 63 is electrically connected to the temperature control component 52. When the switch button 43 is pressed in this way, the switch button 43 presses the switch piece 41, and the switch piece 41 contacts the switch fixing ring 42, so that the entire circuit is turned on. When the push button is released, the switch moving plate 41 is separated from the Guan Dinghuan 42 by the elastic restoring force of the switch moving plate, and the push button 43 is lifted up, so that the whole circuit is broken. The barrel 10 is provided with a through hole, and the switch button 43 protrudes from the through hole so that an operator can press the switch button 43.

That is, when the rotating head 20 is rotated, the rotating head 20 drives the copper needle 63, the heating wire 61, the copper needle fastening member 62, the temperature control module 50, and the negative electrode connection piece 53 to rotate together. Wherein the inner surface of the pen container 10 is provided with an annular bulge 13, the copper needle fastening piece 62 is correspondingly provided with an annular groove 621, and the annular bulge 13 is clamped into the annular groove 621 so as to guide the copper needle fastening piece 62 to rotate 360 degrees.
