Problems solved by technology

[0004] The inventors have found that when the existing soft mirror sheath performs negative pressure suction on stone chips after kidney stone (more than 2cm) lithotripsy, the suction effect on the stone is not good, because the passage of the negative pressure suction pipeline is cut off. The area cannot meet the requirements, and the crushed stones are easily blocked when they are sucked out by the negative pressure suction pipeline. economic burden
Moreover, the existing soft mirror sheath needs to install the suction component inwardly when suctioning the gravel, which can neither meet the timeliness nor delay the operation time

Embodiment 1

[0063] Attached below Figure 1-Figure 6 The soft mirror sheath disclosed in this embodiment is further described;

[0064] Such as figure 1 As shown, an integrated flexible ureteroscope sheath includes a sheath tube 1. The sheath tube 1 is a hollow pipeline. A partition 2 is arranged inside the sheath tube 1 to separate the hollow pipeline into a perfusion inlet pipeline 3 and a suction pipeline. The outlet pipeline 4, the perfusion inlet pipeline 3 and the suction outlet pipeline 4 are not connected to each other; both ends of the partition 2 are fixedly connected to the inner wall of the sheath tube 1; the partition 2 is arranged axially along the sheath tube 1, and the irrigation inlet pipeline 3 Set the filling water inlet 5 at the non-working end, the filling water inlet is connected with the filling flushing pump, and the suction outlet pipeline 4 is provided with a negative pressure suction port 6 at the non-working end, and the negative pressure suction port is conne...

Embodiment 2

[0088] The flexible ureteroscope sheath in this embodiment, as Figure 13 As shown, it includes the perfusion water inlet pipeline 10 and the suction water outlet pipeline 11 that are not connected to each other. Both the perfusion water inlet pipeline 10 and the suction water outlet pipeline 11 are hollow pipelines. The two are arranged in parallel and fixedly connected, wherein the filling water inlet pipeline 10 is provided with a water inlet 12 at the non-working end, and the water inlet is connected with the irrigation flushing pump, and the suction outlet pipeline 11 is provided with a negative pressure suction port 13 at the non-working end. The pressure suction port communicates with the negative pressure suction pump. The cross-sectional area of ​​the suction outlet pipeline 11 is larger than the cross-sectional area of ​​the pouring water inlet pipeline 10 to ensure the area of ​​the suction outlet pipeline and avoid blockage of the suction outlet pipeline.

Abstract

The invention discloses an integrated flexible ureteroscope sheath, which comprises a sheath tube. The sheath tube is a hollow pipeline; a partition plate is arranged in the sheath tube to divide thehollow pipeline into a perfusion water inlet pipeline and a suction water outlet pipeline; the perfusion water inlet pipeline and the suction water outlet pipeline are not communicated with each other; the partition plate is arranged in the axial direction of the sheath tube; a perfusion water inlet is formed in the non-working end of the perfusion water inlet pipeline; and a negative pressure suction port is formed in the non-working end of the suction water outlet pipeline.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an integrated flexible ureteroscope sheath. Background technique [0002] Renal calculi are caused by the abnormal accumulation of some crystalline substances (such as calcium, oxalic acid, uric acid, cystine, etc.) and organic matrix (such as matrix A, acidic mucopolysaccharide, etc.) in the kidney, and are common diseases of the urinary system , frequently-occurring disease, 90% contain calcium, and calcium oxalate stone is the most common among them. [0003] At present, the treatment methods for kidney stones are as follows: physical excretion of stones by drinking plenty of water; extracorporeal shock wave lithotripsy; traditional open surgery; percutaneous nephrolithotomy; minimally invasive surgery. [0004] The inventors have found that when the existing soft mirror sheath performs negative pressure suction on stone chips after kidney stone (more than 2cm) li...
