Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a disposable renal pelvis endoscope with integrated negative pressure suction and perfusion, which has the function of removing renal pelvis stones. Background Technology

[0002] Urinary tract stones are a common and frequently occurring disease in urology. With the continuous development of endoscopy technology and the improvement of lithotripsy equipment and stone removal tools, the treatment options for urinary tract stones have been improved. Traditional open surgery has been gradually replaced by minimally invasive treatment methods represented by pyeloscopy, mainly using flexible pyeloscope (ureteroscope) laser lithotripsy and treatment of kidney stones.

[0003] Nephroplasty (flexible endoscopy) is one of the effective tools for treating kidney stones. The endoscope can locate the stone within the renal pelvis by changing the angle of the ureter, and then break it up with the help of a holmium laser. Traditional flexible endoscopes do not have the combined functions of negative pressure suction for stone fragmentation and irrigation, limiting their ease of operation during surgery. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the purpose of this utility model is to provide a disposable renal pelvis endoscope with integrated negative pressure suction and perfusion, which has the function of removing renal pelvis stones and has the integrated function of negative pressure suction lithotripsy and perfusion.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A disposable renal pelvis endoscope with integrated negative pressure suction and perfusion includes an endoscope handle, the tip of which has a forward-extending insertion tube; the side of the endoscope handle has an A-type Luer male connector, which has a second channel that passes through the insertion tube; the outer end of the A-type Luer male connector away from the endoscope handle has a hollow instrument section, which has a through-connected A-type Luer female connector, B-type Luer male connector, and fiber optic basket entry channel;

[0007] The B-type Luer male connector is equipped with a three-way valve connector, which in turn has separately arranged B-type Luer female connectors, water injection connectors, and negative pressure suction stone crushing connectors. ， The three-way valve connector is equipped with a switch handle that controls the connection between the B-type Luer connector, the water injection connector, and the negative pressure suction stone crushing connector.

[0008] Furthermore, in some embodiments, the A-Luer female connector on the instrument section is fitted with the A-Luer male connector.

[0009] Furthermore, in some embodiments, the water injection connector and the negative pressure suction stone crushing connector adopt a universal Luer male connector.

[0010] Furthermore, in some embodiments, the three-function valve connector is provided with a switch handle for controlling the connection between the B-type Luer female connector and the water injection connector;

[0011] The three-way valve connector is equipped with a switch handle that controls the connection between the B-type Luer female connector and the negative pressure suction stone crushing connector.

[0012] This invention features a three-way valve connector in the instrument section, enabling dual functions of irrigation (water inlet connector) and negative pressure suction lithotripsy (negative pressure suction lithotripsy connector). Traditional endoscopes lack this negative pressure suction lithotripsy function. The water inlet connector (water inlet interface) connects to the water supply, ensuring a clear view through the flexible endoscope and removing heat generated by the holmium laser to prevent burns to the mucous membrane. The negative pressure suction lithotripsy connector (negative pressure suction lithotripsy interface): when the holmium laser breaks the stone into powder, this interface allows the stone to be extracted from the second channel. This invention allows for flexible switching between water inlet and negative pressure suction lithotripsy functions via a switch handle, meeting different needs during surgery.
