Description

Technical Field

[0001] The invention relates to the technical field of stone surgical instruments, in particular to a stone crushing and suction device after urological stone surgery. Background Art

[0002] Kidney stones are the main diseases of human kidneys. There are multiple stones and granular stones. Granular stones are large and must be crushed before being removed from the human body. There is no special kidney stone crushing and suction device in the prior art. Ordinary lithotripsy forceps are used for surgical clamping. The size of the crushed kidney stones is uneven, and some are powdery, which is difficult to clamp and remove.

[0003] The Chinese patent publication number is CN 203874174U, which discloses a kidney stone crushing and suction device. The inner sealing cap of the device is funnel-shaped, the inner sealing opening is cross-shaped, the reinforcing ribs and the cross-shaped inner sealing opening correspond to the suction device, and an endoscope can be inserted into the suction device to observe the stone crushing condition; it can also be connected to a suction pump to suck the crushed stones out of the human body; the structural design is simple and reasonable, the suction effect is good, and the operation is convenient and safe to use.

[0004] However, the device drives the suction tube to move to the location of the stone fragments by pushing the suction seat, and then absorbs the stone fragments. Since the device is moved by medical personnel manually, in actual use, the operator may cause a large deviation between the suction tube and the target position due to improper hand strength control. This deviation may not only lead to poor suction effect and ineffective removal of stone fragments, but more seriously, if the suction tube accidentally contacts the surrounding healthy human tissues or organs, it is very likely to cause unnecessary damage.
