The utility model provides an above-mentioned technical problem's technical scheme as follows: an integrated ureteroscope comprises a ureteroscope body, wherein a negative pressure suction channel is arranged in the center of the ureteroscope body, a first channel, a second channel, a third channel and a fourth channel are arranged on the wall of the ureteroscope body around the negative pressure suction channel, an objective lens is arranged at the front port of the first channel, and an eyepiece lens is arranged at the rear port of the first channel; a front port of the second channel is provided with a light source, and a rear port of the second channel is provided with a light source connector connected with the light source; the third channel and the fourth channel are respectively used for penetrating the optical fiber superconducting wire and water inlet and outlet.
The utility model has the advantages that: under the condition that function and overall size are close with prior art, the utility model discloses can obtain the bigger size negative pressure suction passageway, promote and reduce the efficiency that the intraureteral fluid temperature and reduce the interior pressure of renal pelvis ureter that reduces, the size that can arrange the stone simultaneously also becomes bigger, the effectual operation time that has shortened has reduced the incidence of relevant complication, has also reduced patient's medical expenses simultaneously.
On the basis of the technical scheme, the utility model discloses can also do following improvement.
Furthermore, the cross section of the fourth channel is in a shuttle shape or a waist shape.
The adoption of the further beneficial effects is as follows: good water supply can still be ensured under the condition that the wall thickness of the ureteroscope is small.
Further, the inner diameter of the negative pressure suction passage is 5Fr to 6 Fr.
The adoption of the further beneficial effects is as follows: the size is relatively regular, and stone blocking is not easy.
Furthermore, the rear end opening of the first channel penetrates out of the outer wall surface of the middle part of the ureteroscope.
Furthermore, the rear end opening of the second channel penetrates out of the outer wall surface of the middle part of the ureteroscope.
Furthermore, the rear end opening of the third channel penetrates out of the outer wall surface of the middle part of the ureteroscope.
Furthermore, the rear end opening of the fourth channel penetrates out of the outer wall surface of the middle part of the ureteroscope.
The beneficial effect of adopting the four steps is that: the external negative pressure of the negative pressure suction channel is not influenced.
