Description

Medical electrode clamp power indication method and device and medical electrode clamp
Technical Field
The invention belongs to the technical field of electrode clamps, and particularly relates to a medical electrode clamp power indication method and device and a medical electrode clamp.
Background
In the medical field, electrode clamps are widely used for clamping and coagulating tissue, especially during surgery. Power control and monitoring of electrode clamps is critical to ensure safety and effectiveness of the procedure. Currently, conventional electrode clamp power indication systems generally rely on a fixed power output, and when using a fixed power output method, the electrode clamp operates at a set power regardless of the clamped tissue thickness. Although simple, the method cannot adapt to the requirements of different tissues, excessive energy can be output on thinner tissues to cause tissue cauterization or ischemia, and on thicker tissues, the hemostatic effect can be influenced by insufficient energy.
With the development of medical technology, the need for precise control of power and energy in modern surgery is becoming more stringent. In the prior art, most electrode clamps do not take into account the actual thickness of the tissue, which makes them useful for different patients or different sites of the same patient. Therefore, there is a need for a medical electrode clamp power indication method that automatically adjusts power output based on tissue thickness and provides real-time feedback to improve the safety and success rate of the procedure.
Disclosure of Invention
In order to solve the problems of lack of self-adaptability, insufficient real-time performance and relatively complex use of the current electrode clamp control scheme, the invention provides a medical electrode clamp power indication method based on dynamic adjustment of tissue thickness, which can solve the defects, improve the safety and success rate of operation and has important clinical application value, and the method specifically comprises the following steps:

Specifically, a thickness value D between the electrode holders holding tissues is obtained by a high-precision sensor. This measurement of the thickness value is critical for subsequent energy calculations. An energy threshold T is calculated from the measured thickness value D using a preset algorithm. This energy threshold T will serve as a benchmark for subsequent energy monitoring and prompting. Improving the energy management and the use efficiency of the electrode clamp in medical operation.
S2, collecting output voltage V and current I of the electrode clamp, and calculating instant power P (t) =V (t) x I (t) of the electrode clamp at a sampling time point;
Specifically, the output voltage V and the current I of the electrode clamp are monitored in real time so as to perform power calculation. By the formula p=v×i, the instantaneous power value at a specific sampling time point can be obtained. This step ensures that we can accurately assess the energy consumption of the electrode clamp during operation.
S3, calculating single continuous accumulation capacity of the electrode clamp, and calculating accumulated total energy E in the current with a single continuous current starting time point as a starting point according to the instant power P (t);
specifically, calculating the cumulative total energy E in the current power-on in accordance with the instantaneous power P (t) in S3 includes obtaining the total energy by integrating the power curve calculation:
Consider the heat E input at one end of the human tissue, which is transferred to the tissue of thickness D during time t. From the total energy input we have:

This is the rate of change of temperature in a certain direction.
The following formula can be derived:

The above formula is arranged, and the simultaneous obtainable temperature change amount deltat is:
The temperature change delta T is obtained by simplifying the formula:
Where ΔT is the temperature change of the tissue from the beginning point of a single continuous energization to the current point of time (in Kelvin K or degrees Celsius), E is the total energy input over a period of time (Joule J), D is the thickness of the tissue (m), A is the cross-sectional area of the tissue (m 2), the thermal conductivity of the K tissue (W/(m.K)), reflecting the thermal conductivity of the tissue, ρ is the density of the tissue (kg/m 3);cp is the specific heat capacity of the tissue (J/(kg.K)).
According to the related experimental data, the safety temperature rise threshold delta T max of human tissues is generally 42 ℃ by considering the factors of the heat taken away by blood circulation, the tissue type, the environmental temperature and the like, so that the safety input energy Emax which is allowed to be accumulated in the working process of the electrode clamp, namely the energy threshold T, can be obtained:
T=Emax＝ΔTmax·ρ·cp·A·D
after the power calculation is completed, the accumulated total energy E generated in the power-on process is calculated step by taking the time point of starting single continuous power-on as a starting point according to the instant power value obtained before. The accumulated value can reflect the energy use condition of the electrode clamp in the whole operation process, and necessary data support is provided for subsequent judgment.
And S4, controlling the prompting device to respond to the change of the proportional relation according to the proportional relation between the accumulated total energy E and the accumulated total energy T.

When the ratio of E to T is changed, the prompting device can be updated in real time, and visual feedback of the energy use condition is provided for an operator.
