Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a bladder nephroscope with temperature detection.
Background
The cystoscope is a medical instrument, in particular a common endoscopic operation tool of the urinary system, and can be used for diagnosing and treating various diseases related to the bladder and the renal pelvis. It is typically composed of a flexible or rigid elongated lens with an image sensor lens and LED or fiber optic light source at the head end to provide sufficient illumination for the endoscope to magnify and transmit high definition images. The interior of the scope tube typically has one or more working channels for introducing surgical tools, such as forceps, blades, laser probes, etc., for treatment and sampling. The cysts-nephroscopes are inserted into the body through the urethra or other route, guiding the lens inside the bladder and the renal pelvis. The doctor can perform therapeutic operations such as cutting out tumors, removing stones, scraping diseased tissue, etc., by checking the pathological conditions of the bladder and the renal pelvis by observing the images on the screen.
Bladder nephroscope surgery is widely used clinically and is considered to be a safe and effective treatment. In some specific cases of bladder nephroscope surgery, temperature detection is important. Wherein: laser lithotripsy: laser lithotripsy is a common cystoscope procedure used to treat urinary tract stones. During laser lithotripsy, the laser may generate heat, and the high temperature may cause damage to surrounding tissue. Thus, monitoring the temperature change of the laser action region can help the physician ensure temperature control during treatment to prevent thermal damage from occurring.
High frequency electrocoagulation surgery: in bladder nephroscope surgery, high frequency electrocoagulation can be used for cutting and hemostasis. During the electrocoagulation process, electrical current is passed through the tissue to generate heat, and high temperatures may cause tissue burns. Through temperature detection, the physician can monitor temperature changes during the electrocoagulation process to ensure accurate control of the tissue and avoid unnecessary damage.
Treatment of tissue lesions: in bladder nephroscope surgery, it may be desirable to treat tissue lesions, such as tumor resection or lesion tissue curettage. In these procedures, temperature detection may help the physician determine the thermal sensitivity of the tissue to avoid exceeding a safe temperature range and reduce damage to normal tissue.
In summary, the use of temperature detection in cystoscope procedures helps to provide real-time feedback and monitoring, ensuring control and safety of temperature during the procedure. By accurately monitoring the temperature change, doctors can better protect the tissues of patients and improve the success rate and safety of the operation.
However, the prior art has some disadvantages.
1. External temperature probe limit: one of the temperature detection methods currently in common use is to use an external temperature probe that is placed near the surgical field to measure temperature. However, due to the distance and isolation between the probe and the tissue surface, the external temperature probe cannot directly contact the surgical field, so that the measurement result may be affected by the surrounding environment, and the temperature change of the surgical field cannot be accurately reflected.
2. Measuring position limit: when using an external temperature probe, only a few specific locations can be selected for measurement, and the whole surgical area cannot be covered entirely. This may lead to missed temperature monitoring of critical sites and a complete knowledge of temperature changes during surgery.
3. The real-time performance is poor: the measurement of the external temperature probe requires a certain time delay, since the temperature change needs to be conducted to the probe position in order to be detected. This delay results in a failure to monitor the temperature change during the procedure in real time and thus to take the necessary measures to adjust in time.
4. Operational complexity: the use of external temperature probes requires additional equipment and operating steps, increasing the complexity and difficulty of the surgical procedure. This can be inconvenient for the doctor and the surgical team and can interfere with the performance of the procedure.
5. Data collection and recording is difficult: the measurement of the external temperature probe usually requires manual recording, which may risk recording errors or omissions. At the same time, the arrangement and analysis of a large amount of surgical data also face certain difficulties.
