Problems solved by technology

The diameter is 1.2mm-1.6mm and the length is greater than 600mm. The pressure difference of water injection is very large and cannot be accurately measured. The invention with the announcement number 204863067U discloses an endoscope. A pressure sensor is installed at the front end of the endoscope tube body. It has a pressure sensor. There is a pressure sensor lead in the endoscope tube. The lead is used to provide power to the pressure sensor and output the pressure signal. The pressure sensor is used to sense the water pressure within the surgical field of view. When the water pressure signal reaches the preset value At this time, the water injection is controlled by the control device
In this prior art, the lead wire of the pressure sensor is inserted in the water injection or instrument channel, which occupies the water injection or instrument channel and affects the operability of the endoscope

Embodiment 1

[0032] Such as figure 1 with figure 2 As shown, an endoscope for real-time wireless pressure measurement at the front end of the mirror includes a tube body 1, a light source 2, a lens 3, a passive wireless pressure sensor 4, a controller 5 for controlling water injection, and a controller 5 for controlling the wireless The pressure signal output by the source wireless pressure sensor 4 is transmitted to the repeater 6 of the controller 5 . The passive wireless pressure sensor 4 is arranged at the front end of the pipe body 1 , and the repeater 6 is arranged between the passive wireless pressure sensor and the controller 5 .

[0033] When in use, the passive wireless pressure sensor 4 arranged at the front end of the tube body 1 monitors the ambient pressure in real time, and wirelessly transmits the pressure signal to the controller 5 through the repeater 6. The passive wireless pressure sensor 4 can use the light source 2 as a power source , no separate power supply is re...

Embodiment 2

[0040] Such as image 3 and Figure 4 Shown, the difference with embodiment 1 is:

[0041] The tube body 1 is provided with an endoscope water injection input pipe 8 and an endoscope return water output pipe 9, the controller 5 includes a second control part, a second pinch valve 51 and a third pinch valve 52, the second pinch valve The valve 51 is set on the endoscope water injection input pipe 8, the third pinch valve 52 is set on the endoscope return water output pipe 9, and the second control part controls through the following steps:

[0042] Step 1: Set the first standard pressure, second standard pressure, third standard pressure and forecast time FT, the third standard pressure is greater than the second standard pressure, the second standard pressure is greater than the first standard pressure, FT is greater than 1 second and less than 60 Second;

[0043] Step 2: The second control part acquires the first pressure signal output by the passive wireless pressure sens...

Abstract

The invention aims to solve problems existing in prior art and seeks out a real time wireless pressure measuring endoscope in a mirror front end, wherein the wireless pressure measuring endoscope does not need to occupy a water injection path. The wireless pressure measuring endoscope comprises a tube body, an illuminant and a lens, and the wireless pressure measuring endoscope also comprises a passive and wireless pressure sensor, a controller used for controlling the water injection as well as a repeater used for passing a pressure signal output by the passive and wireless pressure sensor to the controller and the passive and wireless pressure sensor is arranged on the front end of the tube body. The real time wireless pressure measuring endoscope in a mirror front end has the advantages that under a condition in which the external dimension of the endoscope is not increased, the wireless pressure measuring endoscope can be used to monitor in real time pressure in human body organs during an operation process, thus guaranteeing the safety of the operation.

Description

technical field [0001] This patent relates to the field of medical devices, in particular to an endoscope for real-time wireless pressure measurement at the front end of a mirror. Background technique [0002] Since the advent of the endoscope, especially the ureteroscope technology has become an indispensable tool for diagnosis and treatment in urology. clinical. However, it has also been found clinically that some patients have severe complications such as postoperative high fever, sepsis, renal pelvis rupture, shock, and even death after ureteroscopy. One of the reasons is that the urinary tract infection was not controlled before the operation, and the other important reason is that the pressure of the renal pelvis is too high: in order to ensure the smooth entry of the mirror and keep the operative field of the lithotripsy site clear, it must be continuously flushed with normal saline during the operation, causing the pressure of the renal pelvis to increase. Increase...
