Description

Technical Field

[0001] The utility model relates to the field of medical technology, and more specifically, particularly to a temperature monitoring and early warning type water-spraying laparoscopic forceps. Background Art

[0002] In clinical practice, minimally invasive surgery has been widely used in surgical treatment in many departments such as general surgery, urology and gynecology; in particular, minimally invasive surgery represented by laparoscopic surgery has become the preferred surgical method for abdominal surgery due to its advantages of less bleeding, shorter operation time and faster postoperative recovery. At present, during laparoscopic surgery, it is usually necessary to use energy devices such as monopolar or bipolar or ultrasonic scalpels for cutting and electrocoagulation hemostasis. Different energy devices or different models of the same energy device generate different amounts of heat during work, and different tissues of the human body have different tolerance to high temperatures. When the energy device is cutting or electrocoagulating hemostasis, the heat generated for a long time leads to excessive temperature, which can easily cause thermal damage to human tissues. This will not only produce eschar, prolong the operation time, affect the safety of the operation and reduce the patient's postoperative quality of life, but also bring great challenges to clinicians in operating laparoscopic surgery.

[0003] In the prior art, a common method for reducing thermal damage to human tissue is to control the interval working time of energy devices by monitoring the impedance of human tissue to reduce heat generation, thereby achieving the purpose of reducing thermal damage to human tissue, or by medical staff spraying water on human tissue to cool it down according to the specific situation of heat generated by energy devices during surgery to reduce thermal damage to human tissue.

During use, when the patient is subjected to surgical treatment such as cutting or electrocoagulation by the forceps head 20 of the laparoscopic forceps structure 1 composed of the forceps tube 10, the forceps head 20 and the forceps handle 30, the temperature information of the human tissue at the surgical site of the patient is transmitted to the thermal pad 42 via the ultrasonic knife tissue pad 41, and the fiber optic Bragg grating temperature sensor 43 of the temperature monitoring and early warning device 4 collects the human tissue temperature information transmitted to the thermal pad 42 in real time, and then transmits it to the fiber optic Bragg grating demodulator 45 in real time via the optical fiber cable 44 for information processing, thereby obtaining the real-time temperature change information of the human tissue and transmitting it to the controller 5, and the display screen of the controller 5 displays the human tissue temperature change information in real time for medical staff to view in real time, and when the monitored and collected temperature information reaches a predetermined high temperature threshold, the voice prompter of the controller 5 sends a warning voice in real time to prompt the medical staff to deal with it in time, thereby realizing effective monitoring and early warning of the human tissue temperature, making the temperature monitoring and early warning more accurate, timely and intelligent.
