Description

Double-channel soft endoscope sheath for washing renal pelvis and calyx of kidney

Technical Field

The utility model belongs to the technical field of renal pelvis renal calyx washing technique and specifically relates to a binary channels soft mirror sheath for renal pelvis renal calyx washing.

Background

In recent years, the incidence of upper urinary tract diseases, particularly kidney stones, has increased year by year, and under-soft-lens procedures such as under-soft-lens laser lithotripsy have also been actively conducted as a main diagnosis and treatment modality of upper urinary tract diseases.

The operation process of the prior art soft lens is as follows: a soft lens sheath is arranged in the ureter after being guided to the lower part by a urethral guide wire, one end of the soft lens sheath is positioned outside the body, the other end is positioned at the junction of the renal pelvis ureter and the soft lens realizes the operations of lithotripsy and tumor biopsy treatment and the like through the soft lens sheath. In the operation process, the visual field is blurred due to the situations of bleeding, turbid urine and the like; and the renal calyx of the renal pelvis collapses (influences the operation space), and the operation is finished by continuously flushing water through the soft lens to ensure that the visual field in the renal pelvis is clear and keeping the renal calyx of the renal pelvis in an expanded state.

The operation of the prior art has the following problems:

only when the soft lens is operated, the flushing water can be ensured to continuously flush in the renal pelvis to ensure the clear visual field and the expanded state of the renal calyx of the renal pelvis. When medical staff withdraws from the soft lens after taking stones and biopsies, a small amount of bleeding, turbid urine and renal pelvis and renal calyx collapse can cause unclear vision and poor operation space, the soft lens is required to be placed again for flushing so as to enable the clear vision and the establishment of the operation space, and then effective operation is carried out. This can affect the efficiency of the soft under-the-lens procedure, increasing the procedure time, and resulting in a corresponding increase in the risk of the procedure.

SUMMERY OF THE UTILITY MODEL

In view of the above, an object of the present invention is to provide a double-channel soft endoscope sheath for washing pelvis and calyx of kidney, the present invention adopts the following technical scheme:

a double-channel soft endoscope sheath for washing the calyx of the renal pelvis comprises an outer tube, an inner tube, an outer cavity, a water filling tube and an inner cavity, wherein one end of the outer tube is inserted into the calyx of the renal pelvis, one end of the inner tube is sleeved in the outer tube, the other end of the inner tube is inserted into the calyx of the renal pelvis and is connected with the other end of the outer tube in a sealing mode, the outer cavity is arranged between the inner tube and the outer tube, the water filling tube penetrates through the outer tube and is communicated with the outer cavity and is used for filling liquid for washing the calyx of the renal pelvis, and the inner cavity is arranged in.

Furthermore, the double-channel soft endoscope sheath for washing the renal pelvis and calyx further comprises a plurality of supporting connecting parts arranged between the inner tube and the outer tube inserted into one end of the renal pelvis and calyx; and a water filling flow channel is arranged between the adjacent support connecting parts.

Preferably, the outer tube has an outer diameter of 16mm and an inner diameter of 14 mm; the outer diameter of the inner pipe is 12mm, and the inner diameter is 10 mm.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model skillfully arranges the inner tube and the outer tube to continuously keep the renal pelvis to be continuously flushed under the condition that the soft lens is not inserted and flushing fluid is not kept (under the condition that the soft lens is withdrawn), which is helpful to continuously ensure clear visual field/good operation space and improve the operation efficiency under the soft lens;

(2) under the condition that the soft lens is withdrawn, the flushing fluid is flushed into the renal pelvis and renal calyx through the outer channel of the soft lens sheath and flows out of the body through the inner channel, so that silt-like calculi after the stones are broken can be flushed out of the body, and the calculi are prevented from remaining;

(3) the upper ends (the end far away from the renal pelvis and renal calyx) of the inner tube and the outer tube of the utility model are connected in a sealing way, and the end near the renal pelvis and renal calyx is connected in a supporting way, so that the integration of the inner tube and the outer tube is ensured, the operation is simpler and more convenient, the repeated drawing and inserting operation is not needed, and the pain brought to the patient by the operation is reduced;

(4) the utility model adopts the outer cavity to feed liquid, and the inner cavity to discharge the liquid after washing, thereby ensuring the single direction of the flow passage and improving the washing efficiency;

to sum up, the utility model has the advantages of simple structure, easy and simple to handle, washing efficiency height, have very high practical value and spreading value at renal pelvis renal calyx washing technical field.
