technical field

The utility model relates to the technical field of medical devices, in particular to a surgical device used for intracavitary surgical treatment of kidney stones and ureteral bladder stones.

Background technique

The urinary tract is the detoxification system of human beings. There are many toxins and sediments in the urine. The urine enters the urinary tract through the filtration of the kidneys. During this metabolic process, the kidneys and the urinary tract often form sediments, which will cause kidney damage for a long time. and urolithiasis. In urological surgery, the removal of kidney stones and urinary calculi requires interventional therapy. In the operation, an endoscope is often used in conjunction with instruments to perform the operation. Endoscope for examination, diagnosis and treatment of the kidney. The authorized announcement number is CN202960448U, and the Chinese patent application number 201220640795.9 discloses a uretero-nephroscope; it includes a mirror tube connected with a mirror tube main body, an observation port is arranged on the mirror tube main body, and a sheath tube is connected to the mirror tube jacket. It is called the outer mirror tube, and the sheath tube is connected with a sheath body, and the sheath body is connected to the main body of the mirror tube through a mirror lock; an objective lens imaging channel and a light guide are arranged inside the mirror tube, and a cleaning channel is provided outside the mirror tube, and the mirror tube and the cleaning channel are both Located in the sheath, there is also an instrument channel in the sheath; the cleaning channel is connected to the liquid inlet on the sheath, the instrument channel is connected to the instrument inlet on the main body, the objective lens imaging channel is connected to the observation port, and a light guide is provided on the main body interface. The uretero-nephroscopic sheath and the sheath body of this structure are integrally formed, and the outer diameter of the sheath is fixed, and the sheath with different outer diameters or lengths cannot be replaced due to different patients or different urinary tracts and pathological conditions; On the one hand, when the existing uretero-nephroscope is performing lithotripsy, the stones need to be taken out of the body through the lumen of the ureteroscope after being crushed by the lithotripsy device. The power of the uretero-nephroscope with this structure is small, and the stones flow out The speed is slow, and the residue is not easy to discharge, resulting in prolonged operation time and increased operation risk, increasing the pain of the patient.

Utility model content

The technical problem to be solved by the utility model is to provide a urological laparoscopic surgical device, which can solve the problem that the uretero-nephroscope cannot be replaced with different outer diameters or lengths due to different patients or different urinary tracts and pathological conditions, and the After the stone is crushed, the flow rate of the broken stone is slow, and the residue is not easy to discharge, which leads to prolonging the operation time and increasing the operation risk, which increases the pain of the patient.

In order to solve the above problems, the technical solution of the utility model is: this urological laparoscopic surgical device includes a connecting body provided with a nephroscopic channel and a suction channel interconnected with each other, and a pressure relief control is provided on the suction channel. valve, the outlet of the nephroscope channel of the connecting body is connected with an outer mirror tube through a rubber joint, and the outlet of the suction channel is connected with a gravel filter collector and a drainage bottle connected with a negative pressure suction port.

Among the above technical solutions, a more specific solution may also be: a uretero-nephroscope is inserted into the channel of the nephroscope.

Further: the connecting body is a four-way joint; the connecting end of the outer mirror tube and the rubber joint is covered with a positioning rubber ring; the outer mirror tube is a metal tube.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following beneficial effects:

1. When the utility model is in use, the uretero-nephroscope is inserted into the channel of the nephroscope, and a rubber joint is arranged on the channel of the nephroscope, and metal tubes of different diameters or lengths are equipped on the connecting body according to the urinary tract of the patient. Pressure relief control valve, the outlet of the pumping channel of the connecting body is connected with a gravel filter collector and a drainage bottle connected with a negative pressure suction port. During the operation, the pressure relief control valve can be adjusted according to the condition of the gravel to control the water flow and negative pressure. , so that the crushed stone can be discharged smoothly, reduce the operation time, reduce the risk of operation, and at the same time reduce the pain of the patient and ease the work difficulty of the medical staff.

2. The utility model uses a rigid metal external mirror tube, which is easy to operate and can pass through the urethra and ureter to reach the renal pelvis; it is used for more advanced transurethral ureteroscopic holmium laser lithotripsy or transurethral hard convection negative pressure channel urine The effect of endovascular surgery is obvious.

3. The utility model changes the current operation mode of minimally invasive treatment of urinary calculi.
