Description
Technical Field
The utility model belongs to the field of medical instruments, and relates to an in-vivo laser treatment protection device.
Background
At present, laser lithotripsy is widely applied, and the working principle is that under the guidance of an endoscope, soft optical fibers enter a human body and approach to stones, and laser emitted by a laser is irradiated on the stones through optical fiber conduction, so that thermal expansion or shock wave effect is generated on the surfaces of the stones or in the stones, and therefore, massive stones are smashed into small blocks or powder which can flow out through the flushing of the endoscope, and the effect of treating the stones is achieved.
Patent CN215960251U discloses a scheme of incorporating a temperature sensing optical fiber transmitting a temperature signal into a conventional holmium laser optical fiber, which tests the temperature near the operation through the temperature sensing optical fiber to determine whether the laser treatment is terminated or not, so as to avoid high temperature damage; however, the CN215960251U needs to make a judgment after the doctor observes the temperature, and if the operation needs to be continued, the doctor needs to observe manually and operate manually during the operation, which inevitably increases the risk of the operation.
Patent CN211271125U discloses a scheme of coating a layer of thermosensitive reversible color-changing coating on a traditional holmium laser fiber, which judges whether the laser treatment is terminated or not by changing the color of the thermosensitive reversible color-changing coating so as to avoid high-temperature damage; however, the patent CN211271125U requires a doctor to judge whether to continue the operation by changing the color of the thermosensitive material, and the environment in the urethra is complex and unstable, meanwhile, the color of the patent is changed to yellow to orange red, the doctor observes the color by means of the television monitoring system, whether the color is obviously changed in the process, whether the color is stable, including whether the judgment of the doctor is accurate, and some human factors may possibly cause the laser treatment to be stopped in time.
Therefore, it is necessary to develop a device capable of actively interrupting the surgical treatment (automatically turning off the laser treatment switch when a certain temperature is reached), and solve the problem of poor accuracy caused by the need of artificial subjective judgment.
Disclosure of Invention

the temperature-sensitive air bag is filled in a cavity which is formed by the right parts of the tube body, the partition plate and the balance plate in a surrounding manner;
the matching relation of all the components is as follows: when the temperature is less than T, the button a presses a trigger button I in a switch for triggering laser treatment; when the temperature is greater than or equal to T, the temperature-sensitive air bag expands to cause the right end of the balance plate to descend and the left end to rise, and the button a does not press a trigger button I in a switch for triggering laser treatment;
t has a value of 50-55 ℃.
One of the purposes of the utility model is to realize the automatic closing of the laser treatment switch when a certain temperature is reached (namely, when the temperature is more than or equal to T); the balance plate is equivalent to a lever, when the temperature is lower than T, the lever is in a balance state I (shown in figure 3), the left end is downward, the right end is upward, and the button a presses a trigger button I in a switch for triggering laser treatment, so that the laser treatment is maintained; when the temperature is greater than or equal to T, the temperature-sensitive air bag expands to generate downward acting force on the right end of the lever, the balance state I of the lever is broken, the right end of the lever is lowered, the left end of the lever is raised, the button a does not press the trigger button I in the switch for triggering laser treatment any more, and at the moment, the laser treatment is turned off.
In the prior art, the related temperature-sensitive gas technology is applied to a trigger switch, most of working principles are that gas is sealed in a gas chamber, and one surface of the gas chamber is pushed to slide through expansion and contraction of the gas, so that the switch is triggered, but multiple movements inevitably lead to leakage of the temperature-sensitive gas, so that the working efficiency is reduced; according to the utility model, the gas is encapsulated through the temperature-sensitive air bag, so that the leakage problem is avoided.
