Embodiment 1

[0011] see figure 1 , a suction stone mirror for percutaneous nephroscopic surgery, comprising an objective lens port 1, a suction stone inlet 2, a water inlet 3, a light source interface 4, a camera interface 5, a suction stone outlet 6, a water inlet interface 7, and a connecting hose connector 8. The hose wall stone storage bottle 9, the stone blocking filter screen 10, the sucker connecting hard tube 11, the stone suction channel 12, the water inlet channel 13, and the light source channel 14 are composed of the water inlet channel 13 and the light source channel 14 respectively attached to the suction Inside the stone channel 12, the light source interface 4 is located at the rear end of the light source channel 14. When the light source is connected, the light passes through the light source channel 14 and shines on the surgical field from the objective lens port 1. The camera interface 5 is located on the same side of the light source interface 4 and is connected to the ...

Embodiment 2

[0013] see figure 1 , figure 2 , during the operation of percutaneous nephrolithotomy, after the stones are crushed, the nephroscope is replaced by the suction stone mirror of the present invention, and the stones are sucked by the controllable negative pressure suction device, and the stones enter the soft stone through the stone suction outlet 6 due to gravity. Tube wall stone storage bottle 9, stone storage bottle 9 is a transparent material, which is convenient for observing the suction situation of calculi in the operation, and the detachable joint 8 is convenient for taking out the calculus after the operation. The stone-blocking filter screen 10 blocks the calculus rushing to the aspirator connecting hard pipe 11, prevents the calculus from clogging the aspirator pipeline, keeps the aspirator unimpeded, and avoids delaying operation; Intake water to keep the surgical field of view clear, and the controllable suction device sucks water intermittently to keep low pressu...

Abstract

The invention provides a calculus suction mirror for percutaneous nephrolithotomy. The calculus suction mirror mainly comprises a hose wall calculus storage bottle, a calculus stopping filtering net, a hard suction device connection tube, a calculus suction channel, a water inlet channel and a light source channel. In the percutaneous nephrolithotomy, the calculus suction mirror quickly sucks larger-size broken calculus through the built-in calculus channel, is favorable for reduction of postoperative calculus residues and operative complications, can improve the calculus removal rate and has the characteristics of saving the operation time, lowering the operation cost, retaining low pressure in the pelvis, guaranteeing the operation quality and the like; the problems of low calculus taking speed and incapability of suction of the larger-size calculus in the percutaneous nephrolithotomy in the prior art are solved. The calculus suction mirror is reasonable in design, integrates photographing, separation flushing and calculus suction, is suitable for tiny broken calculus suction and larger-size broken calculus suction, and can suck the calculus with the maximum diameter which is 4 times larger than the inner diameter of an ultrasonic detection rod.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a stone suction mirror for percutaneous nephroscopic surgery. The stone suction mirror replaces other nephroscopic instruments in percutaneous nephroscopic surgery to absorb nodules in the kidney during the operation. stone. Background technique [0002] Clinically, lithotripsy operation of percutaneous nephroscopic lithotripsy must first crush the stones and then use water perfusion pressure to discharge the stones from the skin-kidney channel, or use the third-generation EMS lithotripsy machine to first use pneumatic ballistic lithotripsy and then remove them from the ultrasonic probe. Aspirate from the rod. The former, when water pressure is discharged from the skin-kidney channel (washing out stones), it is easy to cause a sharp increase in the internal pressure of the renal pelvis, causing a large number of bacteria and toxins in the urine to enter the circulatory s...
