Description
Technical Field
The invention relates to the field of medical instruments, in particular to a stone breaking and taking basket.
Background
Stones refer to solid masses formed in the lumen of a catheter or in the lumen of a luminal organ (e.g., renal pelvis, ureter, bladder, gall bladder, bile duct, pancreatic duct, etc.) within the body. The clinical manifestations of the stones at different positions are quite different, and the stones at the same position have different clinical manifestations due to the size of the stones, whether secondary infection exists or not, and the like. Kidney stones are a common urological disorder, and are a series of symptoms caused by the deposition of stones formed by components in urine on kidneys, and are mainly manifested by pain, hematuria, difficult urination and the like. Patients typically develop macroscopic or microscopic hematuria, the latter being more common. If the secondary infection is manifested as acute pyelonephritis and pyogenic kidney disease. The severe obstruction caused by bilateral upper urinary tract stones can lead to uremia in patients. Typical symptoms of vesical stones are sudden interruption of urination, pain radiating to the distal urethra and glans penis with difficulty in urination and bladder irritation. Bile duct and gall bladder stones are common diseases of the digestive tract.
At present, the treatment of the stones is mostly a minimally invasive surgery treatment means, and the treatment means is that the stones are smashed and taken out by using corresponding tools under an endoscope, so that the treatment effect is achieved. The laser lithotripsy should have high lithotripsy efficiency and small damage to patients and be widely applied. However, for safety reasons, in order to ensure that laser energy aims at stones rather than hits the tube wall to cause tissue damage, the current laser lithotripsy operation must be performed under the direct view of an endoscope, which also causes the rise of operation cost, the increase of operation difficulty and the extension of operation time. The stone basket is an indispensable positioning tool of the stone breaking and taking tool, is mainly used for sleeving stones, and can assist in breaking stones in situ in laser lithotripsy or ballistic lithotripsy. The position of the laser fiber in the current stone-taking basket technology is difficult to control, and a lot of time is required for adjusting the position of the laser fiber in the operation. In addition, the big stone can be easily shifted, not only the stone breaking effect is poor, but also the phenomenon that the laser strikes the biliary wall to cause biliary tract injury or hemorrhage exists.
Therefore, a new instrument which does not need endoscope direct vision guidance, but can sleeve and restrain stones under the guidance of X-ray images, and is convenient and safe to use laser fibers is needed.
Disclosure of Invention
The invention aims to provide a stone crushing and taking basket, which is used for sleeving and fixing stones under the guidance of X-ray images, so that the built-in and centered laser optical fiber can aim at the sleeved stones to crush the stones, and the laser stone crushing operation is not needed to be performed under the direct view of an endoscope, thereby reducing the operation cost, reducing the operation difficulty and improving the operation safety.
It should be pointed out that the lithotripsy and lithotripsy basket provided by the invention can be used under the direct view of an endoscope, can prevent the displacement and the movement of stones in the laser lithotripsy operation and shortens the operation time.
In addition, the broken stone extraction basket provided by the invention can extract stones conveniently during breaking stones, and the operation efficiency is greatly improved.

Preferably, the furthest distance between the slider and the sheath tube end is 60mm.
Preferably, the metal net is composed of four metal wires, the metal wires can be contracted and expanded, and when the metal net is in an expanded state, the middle part forms a cavity.
Preferably, when the metal mesh is in a tightened state, the optical fibers or guide wires can enter and exit the basket through the central through hole of the end cap.
Preferably, the length of the broken stone extraction basket is 40-45cm.
Preferably, the positions of the outer sheath and the inner sheath are fixed, and the sliding sleeve slides between the outer sheath and the inner sheath.
