Pneumoperitoneum tube device with real-time displaying and temperature adjusting functions

Abstract

The invention discloses a pneumoperitoneum tube device with real-time displaying and temperature adjusting functions. The pneumoperitoneum tube device comprises an air heating device and an air detecting, displaying and adjusting device, wherein the air detecting, displaying and adjusting device is connected with the air heating device; the air heating device is connected with a pneumoperitoneum tube (14) through an air intake tube (12), and is also connected with an air exhaust tube (3) which extends into an abdominal cavity. The pneumoperitoneum tube device has the advantages that the structure is simple, and the convenience in operation and use is realized; the pneumoperitoneum tube device is connected with the air exhaust tube of the pneumoperitoneum device, and the temperature of air which is sent into the abdominal cavity can be monitored, displayed and adjusted in real time, so as to realize the overheat protecting function, guarantee that the temperature of the air entering the abdominal cavity of a patient is the optimum temperature for check and operation, and greatly reduce the complication caused by low temperature of the patient; the accuracy and success rate of check and operation by a doctor are improved, and the necessary auxiliary equipment is provided in the use process of the pneumoperitoneum machine.

Description

technical field [0001] The invention relates to the field of laparoscopic instruments and equipment, in particular to an insufflation tube device used in conjunction with a laparoscopic insufflation machine, capable of adjusting gas temperature and displaying the temperature in real time. Background technique [0002] As a new type of surgical instrument integrating diagnosis, positioning, and treatment, laparoscopy can make patients less trauma, less bleeding, less postoperative pain, fewer complications, and faster recovery during the diagnosis and treatment of intra-abdominal organ diseases. Fast and other advantages, has gradually replaced the traditional open surgery. In recent years, laparoscopic surgery has developed rapidly and is currently the most advanced and cutting-edge minimally invasive technology. Its role in the diagnosis and treatment of surgical diseases has attracted more and more attention. [0003] During laparoscopic surgery, in order to obtain a good...

Problems solved by technology

However, the gas temperature output by the insufflator machine currently used clinically is relatively low, usually room temperature; after the gas lower than the human body temperature enters the abdominal cavity, it needs to absorb the heat of the human body in order to achieve consistent with the body temperature of the human body, continuous room temperature gas Enter the human body and continuously absorb the heat of the body; the tension formed by the pneumoperitoneum produces mechanical compression on the abdominal organs, a large amount of blood stored in the viscera is transferred to the systemic circulation, more heat spreads outward through the dilated blood vessels, and patients are prone to perioperative hypothermia

Hypothermia reduces the anti-infection ability of surgical incisions, delays wound healing, increases blood loss, increases the incidence of cardiovascular diseases, induces shivering and acidosis, and ultimately affects postoperative recovery of patients, increases patient pain, and increases social burden

In addition, the colder gas enters the human body and absorbs the heat of the human body. The water vapor in the abdominal cavity is atomized into water droplets and condenses on the lens, resulting in blurred surgical vision. The surgeon needs to constantly pull out the lens to remove the water mist, which affects the operation and delays the operation time. , reducing the surgeon's satisfaction with the equipment

Therefore, the gas needs to be reheated. In the prior art, there are relatively few improvements about the insufflation machine. The patent with the publication number CN2744305 discloses a kind of high-pressure insufflation tube called "the insufflation machine with the intake filter mechanism". The patent of "is to improve the air quality input into the patient's abdominal cavity through air filtration equipment, but fails to ensure the appropriate temperature of the filtered gas input into the patient's abdominal cavity. In the prior art, although some equipment has a heating function, But it is only a simple heating function. When the temperature exceeds the temperature of the human body, it is not easy to be found, and there may be a potential overheating danger. This technology cannot directly reflect the real-time temperature status, and the temperature cannot be adjusted
