Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, when the voltage output of the forced coagulation mode starts to be output, the instantaneous energy is more when the voltage change is larger from V0 to Vmax, the conductor at the part is easily conducted due to high voltage difference, unnecessary energy loss is generated, and the tissue damage can be caused by the part of energy. Based on the above technical problem, the present embodiment provides a voltage output method, specifically referring to fig. 2, where fig. 2 is a flowchart of the voltage output method provided in the present embodiment, and the method specifically includes:
s101, obtaining a blood coagulation instruction; wherein the coagulation instruction comprises a coagulation voltage;
the main implementation body of this embodiment is a voltage output device, which may provide one or more input/output interfaces for a user, where the input/output interfaces are connected to an input device, and receive instruction information or parameters manually input by the user, where the input device may be a touch screen, a keyboard, a mouse, a microphone, and the like, and then, through the one or more input/output interfaces, the instruction information or parameters input by the user may be acquired, and a coagulation instruction for outputting voltage for coagulation is created according to the instruction information or parameters. The coagulation instruction may include a coagulation voltage for performing coagulation of the portion to be treated under the voltage, and of course, the coagulation instruction may also include an Identity document (ID code) of the high-frequency electrotome. It will be appreciated that the coagulation voltage may be set by the user as the case may be. This embodiment is not limited.
Further, after receiving the blood coagulation instruction, the method further comprises: acquiring the ID of the current high-frequency electrotome; and matching the ID of the current high-frequency electrotome with the ID of the medium-high frequency electrotome in the blood coagulation instruction, executing the step S102 after the matching is successful, and if the matching is failed, not executing voltage output and sending prompt information to prompt a user. Therefore, the problem of issuing wrong instructions is avoided through the matching of the IDs, and the safety of the operation is improved.
And S102, outputting the voltage from the initial output voltage according to a curve of the voltage gradually rising along with the time until the coagulation voltage is output according to the coagulation instruction.
The gradual increase curve in the present embodiment is a curve in which the voltage increases with time, wherein the gradual increase curve may be a curve in which the voltage is output at a set voltage gradient at preset time intervals, and the voltage gradient may be gradually decreased or may be maintained. For example, when the initial output voltage is increased to the coagulation voltage within the time from 0 to t, the time period is divided into 4 sections according to a preset time interval, and a first voltage is output within the 1 st section, wherein the first voltage is the initial output voltage plus a first voltage gradient; the voltage output in the 2 nd period is a second voltage which is the first voltage plus a second voltage gradient; the voltage output in the 3 rd period is a third voltage which is the second voltage plus a third voltage gradient; the voltage output in the 4 th period is a fourth voltage which is a coagulation voltage; it will be appreciated that a fourth voltage gradient exists and that the fourth voltage may be the sum of the third voltage and the fourth voltage gradient, when the sum is just the same as the coagulation voltage, or the coagulation voltage is taken as the fourth voltage when the sum of the third voltage and the fourth voltage gradient is greater than the coagulation voltage. The first voltage gradient, the second voltage gradient and the third voltage gradient may be the same or may be sequentially decreased. Of course, the gradual rise curve may also be a linear rise curve of voltage and time. It is noted that the gradual increase curve in this embodiment does not have a direct jump from the initial output voltage to the coagulation voltage, and this embodiment may be to reduce the occurrence of tissue damage.
In one embodiment, the step of outputting the voltage according to a gradually rising curve of the voltage along the time from the starting output voltage until the coagulation voltage is output comprises:
outputting a voltage corresponding to the current time according to Vn-1+ (Vmax-Vn-1)/k + 1;
wherein Vn-1 is the voltage output at the last moment of the current time, k is the rising curvature, Vn is the voltage output corresponding to the current time, and Vmax is the coagulation voltage.
Specifically, referring to fig. 3, fig. 3 is a schematic diagram of a relationship between a voltage output and time provided in an embodiment of the present application, in which an abscissa represents time and an ordinate represents voltage; v0 is the initial output voltage; vmax is the coagulation voltage (i.e. the highest output voltage); vm is the final voltage after completion.
A voltage rising part: vn-1+ (Vmax-Vn-1)/k +1, wherein Vn-1 is the output voltage at the last moment, k is the rising curvature, and 1 is added to ensure the output to the highest voltage; and when Vn is larger than Vmax, Vmax is output. Therefore, the problem of tissue damage caused by transient pressure difference can be avoided by adopting a voltage change rising mode in the embodiment. Specifically, the formula Q ═ (U ^2/R) × T can be obtained as follows:
Qn-1＝(Vn-1^2/R)*T；
Qn＝((Vn-1+((Vmax-Vn-1)/k+1))^2/R)*T；
Qn-Qn-1＝(2*Vn-1+((Vmax-Vn-1)/k+1))*((Vmax-Vn-1)/k+1)/R)*T；
wherein R, T is a constant value, ((Vmax-Vn-1)/k +1) is a voltage difference of two times, and Qn-Qn-1 is an energy difference of two times. According to the design principle, the difference ((Vmax-Vn-1)/k +1) is gradually reduced and is larger than 1 in the rising process, so that the output energy difference is in a curve rising state. The mode can meet the requirement that the energy output rises along with the increase of time, and can avoid too large output energy difference caused by too fast rising, thereby influencing tissues due to too fast temperature change and also avoiding the influence of too fast output energy change on feedback measurement precision.
In another realizable embodiment, the voltage is output according to a gradual voltage increase curve with time from the initial output voltage until the coagulation voltage is output, including:
and outputting the voltage according to a linear gradual voltage increase curve with time from the initial output voltage until outputting the coagulation voltage. In an implementable embodiment, there may be a coagulation voltage rising from the starting output voltage by a value according to a slope 1, an intermediate voltage rising from the starting output voltage by a value according to a slope 2, a coagulation voltage rising from the intermediate voltage by a value according to a slope 3, although other forms may also be present. Therefore, the voltage is increased according to the linear gradual increase curve, the slope is not limited in the embodiment, and the user can customize the setting.
Further, according to the blood coagulation command, the method comprises the following steps of outputting the voltage according to a gradual voltage increase curve with time from the initial output voltage until the blood coagulation voltage is output: and after the coagulation voltage is continuously output within a preset time period, outputting the voltage according to a curve that the voltage is gradually reduced along with the time until the final voltage is output.
When the coagulation voltage is reached, the coagulation voltage is continuously output within a preset time period to finish coagulation, and then the voltage is output according to a gradually reduced curve until a final voltage is output. In this embodiment, the voltage gradual decrease curve is not limited, and the voltage may be output in a gradient decrease mode, may be gradually decreased according to a fixed decrease gradient, or may be output in a linear decrease mode.
Wherein, according to the gradual reduction curve output voltage of voltage along with time, until exporting final voltage, include: and outputting the voltage in a gradient descending mode until the final voltage is output.
Referring to the voltage output after Tm in fig. 3, the voltage is output in a gradient decreasing manner. The embodiment adopts a mode that the output voltage is gradually reduced to change the energy output, and the energy output is reduced as soon as possible, so that the influence of excessive energy output on tissues is reduced, the energy output time is prolonged, the temperature is in a curve reduction mode, and the temperature difference between the knife pen and the tissues (the temperature of the knife pen is higher than the temperature of the tissues) is ensured, so that the phenomenon of knife sticking is prevented.
Based on the technical scheme, the voltage of the embodiment is output from the initial output voltage according to the gradual rising curve of the voltage along with the time, and the voltage is output in the voltage change rising mode, so that the problem of tissue injury caused by the fact that the related technology directly jumps from the initial output voltage to the coagulation voltage is solved.
