Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a renal pelvis internal pressure control system.
Background
Kidney stones are common disorders of urinary surgery, and their incidence tends to increase. With the development of medical devices, the mainstream of treatment thereof is gradually changed from traditional surgery to minimally invasive surgery. In general, when minimally invasive surgery is performed on kidney stones, in order to keep the visual field clear and flush out the stones, washing and perfusion of the renal pelvis are often performed, but the current standard operation may still cause the rise of the internal pressure of the renal pelvis, so that the perfusate containing bacteria and endotoxin is absorbed through the kidney in a reflux manner, and postoperative fever and sepsis are caused. Therefore, the internal pressure of the kidney is continuously and effectively monitored, and the internal pressure of the renal pelvis is controlled to be a certain level, so that the occurrence of renal reflux can be reduced, and the safety of minimally invasive renal calculus surgery is provided.
In the early days, the traditional method of measuring central venous pressure and reading water column was used for measuring the internal pressure of the renal pelvis, wherein when the water column rises, the pressure of the renal pelvis is larger than the water column pressure, and when the water column falls, the pressure of the renal pelvis is smaller than the water column pressure, and only the pressure reflected when the water column is stationary is the true pressure of the renal pelvis. In actual operation, the measured water column is always in a fluctuating state, the accurate measurement is required to be performed when the water column is in a static state, the process is complicated, the operation is affected, the pressure fluctuation is difficult to record in real time, and the conduction of the renal pelvis pressure wave has hysteresis, so that the traditional water column reading method has no practical clinical significance.
The actual pressure within the renal pelvis is not known, and an open design is generally made between the mirror and the sheath, so that water flows out of this intermediate gap once the pressure of the renal pelvis is too high. But the drainage is not smooth, so in the general operation process, the side assistant takes the injector to pump water into the channel of the endoscope. The result is a poor visual field, an unknown water flow, an unknown pressure, and a complete judgment based on the experience of the doctor.

The irrigation and suction device 2 is also provided with an operation panel 26 for displaying parameters such as pressure, flow and the like and controlling the flow of inlet water and outlet water. The operating panel 26 displays the parameters of irrigation and suction under pressure and, based on the data obtained by the pressure sensor 34, the pressure inside the renal pelvis. The internal pressure of the renal pelvis is regulated by controlling the speed of water intake from the water inlet pipe 23 and the speed of water outlet from the water outlet pipe 24 by adjusting the flow rate of perfusion and the flow rate of suction of negative pressure through buttons on the operation panel 26. Generally, the rate of water entry is unchanged, the rate of water exit is changed, and when the internal pressure of the renal pelvis is too high, the water entry is reduced or disconnected to protect the renal pelvis when the internal pressure exceeds a warning value.

Specifically, the sucking and filling device 2 is provided with a driving piece 5, the driving piece 5 is used for driving physiological saline in the water inlet pipe 23 to flow forwards, the driving piece 5 comprises a driving motor 51 and a driving wheel 52 connected to an output shaft of the driving motor 51, the driving motor 51 is located inside the shell 21, the driving wheel 52 is located outside the shell 21, the flow sensor 25 is arranged on one side of the driving wheel 52, and the water inlet pipe 23 is wound on the driving wheel 52 and passes through the flow sensor 25.
In order to fix the water inlet pipe 23 and prevent the water inlet pipe 23 from being separated from dislocation under the drive of the driving wheel 52, a first fixing piece 53 and a second fixing piece 54 are further arranged on one side of the driving wheel 52, the first fixing piece 53 and the second fixing piece 54 are both fixed on the shell 21, the fixing mode can be glue bonding or bolting, grooves are formed in the first fixing piece 53 and the second fixing piece 54, the water inlet pipe 23 is buckled in the grooves, and the first fixing piece 53 and the second fixing piece 54 are arranged side by side up and down, so that the water inlet pipe 23 is in a parallel state around the driving wheel 52.
A plurality of press rollers 55 are provided in the circumferential direction of the drive wheel 52, and the plurality of press rollers 55 are uniformly provided in the circumferential direction of the drive wheel 52. When the water inlet pipe 23 is wound on the driving wheel 52, the pressing rollers 55 prop against the water inlet pipe 23 to form an extrusion effect when the driving wheel 52 rotates, and the pressing rollers 55 arranged at intervals intermittently extrude the physiological saline in the water inlet pipe 23, so that a stable and continuous water outlet effect can be formed at the water outlet 37 of the front end part 33 due to the longer pipeline of the soft lens body 32. The flow sensor 25 is a clamp type sensor and is also not in direct contact with the physiological saline in the water inlet pipe 23, thereby reducing the occurrence of infection.
The housing 21 is further provided with a cover 27, and the cover 27 covers the driving wheel 52 and the flow sensor 25 to prevent collision with the driving wheel 52 and the flow sensor 25 during operation, influence on water inflow and prevent malignant events. The cover 27 is preferably hinged to the housing 21, but may be snap-fit to the housing 21, in which case the connection is preferably hinged.
Referring to fig. 1 and 2, the irrigation and aspiration device 2 is further provided with a drainage mechanism 6, and the drainage mechanism 6 is connected with a water outlet pipe 24 to aspirate physiological saline in the renal pelvis in a negative pressure suction manner. Specifically, the drainage mechanism 6 includes a vacuum pump 61 and a waste liquid barrel 62, the waste liquid barrel 62 can be fixed on the frame 1, the fixing mode is not limited, the vacuum pump 61 is arranged in the shell 21, the vacuum pump 61 is connected with the waste liquid barrel 62 through a pipeline, the water outlet pipe 24 is connected with the waste liquid barrel 62, the control unit 22 controls the operation of the vacuum pump 61, and then controls the negative pressure in the waste liquid barrel 62, and the waste physiological saline flowing out of the water outlet pipe 24 is collected in the waste liquid barrel 62. The control unit 22 controls the operation of the vacuum pump 61, and further controls the magnitude of the negative pressure in the waste liquid tank 62, thereby adjusting the speed at which the negative pressure attracts the physiological saline.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
