Description
Technical Field
The invention relates to a medical instrument, in particular to an automatic pressure regulating type stone crushing and removing system.
Background
Endoluminal treatment is the main form of renal stone treatment at present, and the specific mode of operation is to enter the kidney from the urethra or body opening with an endoscope and to crush the renal stones with laser. The form of the intracavity therapy is generally popularized and used due to the advantages of minimal invasion or no invasion, small harm to the body and the like.
In the operation process, in order to ensure that the endoscope has a good operation visual field in the kidney and facilitate doctors to observe the conditions and operation effects in the kidney, a liquid inlet channel is usually constructed along with the endoscope, so that the liquid inlet channel is used for introducing physiological saline, supporting the space in the kidney and constructing a waste liquid discharge channel at the same time, so that gravels generated in the operation are discharged in time and the pressure in the kidney is balanced.
When the existing stone crushing and removing system for intracavity treatment works, the pressure in the kidney depends on the difference value of the liquid inlet flow rate and the liquid discharge flow rate, namely the liquid filling amount in the kidney. Different flow rates are required to be matched in different operation stages in the whole operation process, for example, in the process of intensively crushing stones, the operation visual field is influenced because the crushed stones are dispersed in liquid, and at the moment, the flow is required to be increased and the crushed stones are taken away in time. When the flow rate of the liquid inlet or the flow rate of the liquid outlet is changed, the pressure in the kidney is changed, and when the pressure in the kidney fluctuates beyond a certain range, the human body can be injured. In the existing system for removing the calculus at any time, doctors need to artificially adjust the liquid inlet flow or the liquid discharge flow when finding that the pressure changes, so that the intrarenal pressure is indirectly adjusted, the response speed is low, and the operation is complicated.
Disclosure of Invention
The invention aims to provide an automatic pressure regulating type stone crushing and removing system, which can automatically balance the intra-renal pressure through a pressure regulating port, reduce intra-renal pressure fluctuation, improve the safety of an operation and simplify the operation procedure of the operation.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: an automatic pressure-regulating type stone crushing and removing system comprises an electronic mirror and a mirror sheath, wherein the electronic mirror comprises a liquid inlet channel; the endoscope sheath comprises a sheath body and a sheath tube, wherein a liquid drainage channel is arranged in the sheath tube, and a transition cavity communicated with the liquid drainage channel is arranged in the sheath body; the sheath body is provided with a liquid outlet and a pressure regulating port which are communicated with the transition cavity; the device also comprises a perfusion device communicated with the liquid inlet channel and a suction device communicated with the liquid outlet; still include the renal pressure monitoring module, the renal pressure monitoring module include the pressure-measuring pipe and with the hydraulic pressure detection device of pressure-measuring pipe intercommunication, hydraulic pressure detection device and pressure-measuring pipe between be equipped with the governing valve, the governing valve on be equipped with the liquid feeding passageway, the pressure-measuring pipe through governing valve and hydraulic pressure detection device and liquid feeding passageway alternative intercommunication.
The pressure regulating port is directly communicated with the atmospheric environment, when the stone breaking and removing system normally works, part of air enters the transition cavity from the pressure regulating port, but the waste liquid entering the transition cavity from the kidney through the liquid discharge channel is preferentially discharged from the liquid discharge port due to the liquid discharge port communicated with the suction device, and meanwhile, part of air enters the liquid discharge port along with the waste liquid under the negative pressure action of the suction device.
