Description

Technical Field

[0001] This application relates to the field of medical technology, and in particular, to a temperature-controlled capacitive negative electrode plate and an electrosurgical unit system dedicated for electrosurgical units. Background Art

[0002] An electrosurgical unit is a medical device that cuts and stops bleeding of human tissues by generating high-frequency current. There are two main operating modes of the electrosurgical unit: monopolar and bipolar. In the monopolar mode, the current cuts and coagulates tissues through a complete circuit, which consists of a high-frequency generator in the high-frequency electrosurgical unit, a patient electrode (i.e., a negative electrode patch or a negative electrode clip), a connecting wire, and an electrode. In the bipolar mode, the current provides high-frequency electrical energy to the body tissue through the two tips of the bipolar forceps, dehydrating and coagulating the blood vessels between the two ends of the bipolar forceps to achieve the purpose of hemostasis.

[0003] The mainstream electrosurgical units are mainly in the monopolar mode, but they have the following defects. Since the electrosurgical unit forms a direct circuit with the human body, when the patient is equipped with implanted electronic devices such as a cardiac pacemaker and an artificial heart, the normal operation of such devices will be affected. When the negative electrode patch and the negative electrode clip do not fit well with the patient's skin, it is easy to generate electric arcs and burn the patient. For the temperature-controlled capacitive negative electrode plate dedicated for electrosurgical units designed based on the capacitance principle, the human body forms a capacitor with the positive electrode and the negative electrode layer to store the electric charge generated during the operation of the electrosurgical unit. When the electrosurgical unit leaves the human body, the capacitor formed by the human body and the negative electrode layer completes the neutralization of positive and negative charges through the electrosurgical unit host. Since there is no substantial current passing through the human body in this solution, it will not affect the operation of in-vivo electronic products and will not generate electric arcs to burn the skin. However, under general anesthesia, due to the disappearance of the patient's consciousness and the application of muscle relaxants, the behavioral thermoregulation of the body is weakened or even disappears, and the autonomous thermoregulation can also be inhibited by general anesthetics. Its characteristics are that the threshold range of the thermoregulation response increases and the intensity of the thermoregulation response decreases. This may cause the patient to experience hypothermia or hyperthermia during the operation, and in severe cases, it may lead to visceral failure and cause serious medical accidents. Therefore, it is very important to control the patient's body temperature under anesthesia. However, the design principle of the capacitive negative electrode plate makes it impossible to use an electric heating (cooling) blanket to maintain the patient's body temperature because inserting a metal mesh layer between the two poles of the capacitor will affect the function of the capacitor, nor can the patient's body temperature be managed in the traditional way of using a water bag because it will increase the distance between the two poles of the capacitor and cause the capacitor to lose its function. Summary of the Utility Model

[0004] The embodiment of this application discloses a temperature-controlled capacitive negative electrode plate system dedicated for electrosurgical units, which can provide temperature adjustment for patients, thereby controlling the hypothermia or hyperthermia of patients and improving the surgical safety of patients.

[0005] In the first aspect of the embodiments of the present application, a temperature-controllable capacitive negative electrode plate for an electrosurgical knife is provided. The temperature-controllable capacitive negative electrode plate for an electrosurgical knife includes: a negative electrode layer; a temperature control layer, a sealing layer, and a temperature control device of the temperature-controllable capacitive negative electrode plate for an electrosurgical knife; wherein,

[0006] The negative electrode layer is electrically connected to the electrosurgical knife main unit. The temperature control layer is arranged at the upper end of the negative electrode layer, and the temperature control layer is completely wrapped by the sealing layer. The temperature control layer is provided with two external interfaces, and the two external interfaces are externally connected to the temperature control device.

[0007] Optionally, the negative electrode layer is also wrapped in the sealing layer.

[0008] Optionally, the sealing layer is a gel layer or a soft material layer.

[0009] Optionally, the temperature control layer includes: a liquid pipeline, and the liquid pipeline is laid flat at the upper end of the negative electrode layer.

[0010] Optionally, the liquid pipeline is laid flat at the upper end of the negative electrode layer in a spiral shape, a grid shape, or an S shape.

[0011] In the technical solution provided by the present application, when the patient lies flat on the temperature-controllable capacitive negative electrode plate for an electrosurgical knife and is anesthetized, the patient's personal body temperature regulation weakens. Assuming that the patient has a certain degree of hypothermia at this time, for example, when the human body temperature is 34 °C, the temperature control device is turned on at this time to heat the temperature control layer 12. For example, it can be heated by water or other liquids (oils), and the heated liquid is used to heat the temperature control layer 12 through the pipeline. In this way, the temperature of the part of the patient in contact with the negative electrode plate will be heated, and the hypothermia of the body will be alleviated, thereby improving the safety of the patient.
