Abstract

The utility model relates to a laser stone removal system, particularly relates to a holmium laser minimally-invasive stone removal system, and mainly solves the existing problems of the prior stone absorption device that the pore diameter through which crushed stones pass is small, the stone removal effect is unideal, and the pressure in a renal pelvis has low probability of being controlled. The utility model adopts the technical scheme that a holmium laser minimally-invasive stone removal system comprises a stone absorption sheath; an endoscope is embedded in the stone absorption sheath; the endoscope and the stone absorption sheath are connected through a positioning sleeve gasket in a sealing manner; optical fibers are inserted into the endoscope; the endoscope penetrates through a stone absorption pipe along the lower end of the stone absorption sheath; a spiral stone absorption cavity is formed in the middle of the stone absorption sheath; a negative-pressure control valve and a negative-pressure aspirator are connected through a lateral absorption pipe in sequence; and a pressure release valve is arranged on the lateral absorption pipe. The utility model can be matched with the endoscope; moreover, the minimally-invasive stone crushing speed is high, the stone crushing and removing operations synchronously conducted, thereby efficiently discharging crushed stones from the human body, and guaranteeing low pressure in the renal pelvis at the same time.

Description

The clear stone system of holmium laser micro-hurt

Technical field

This utility model relates to the clear stone system of a kind of laser, the clear stone system of particularly a kind of holmium laser micro-hurt.Can cooperate the use of endoscope, Wicresoft, rubble are fast, and the clear stone of rubble carries out synchronously, and efficiently rubble is excreted, and guarantee to be in the renal pelvis low pressure simultaneously.

Background technology

Urinary system calculus is that the height morbidity in the urological diseases is planted, and the treatment of urinary system calculus is transferred to the Minimally Invasive Surgery treatment from traditional open surgery.Cooperate high-power holmium laser lithotripsy through endoscope, it adapts to, and calculus kind is the widest, and lithotrity effect is good, goes out insufficiency of blood, infects for a short time, but clear stone effect is general, and the renal pelvis internal pressure is higher relatively in the easily residual and rubble process of small stone, causes easily to infect to cause complication.More existing suction stone devices, unreasonable structure, the aperture that rubble passes through is little, and clear stone effect is undesirable, and the renal pelvis internal pressure is wayward.

The utility model content

The purpose of this utility model is to provide a kind of renal pelvis internal pressure low, and rubble is fast, and clear stone particle diameter is big, and clear stone speed is fast, discharges the clear stone system of holmium laser micro-hurt completely.Solve mainly that existing to inhale the aperture that rubble that the stone device exists passes through little, clear stone effect is undesirable, the uppity technical problem of renal pelvis internal pressure.

The technical solution of the utility model is: the clear stone system of a kind of holmium laser micro-hurt, comprise and inhale the stone sheath, inhale in the stone sheath and be mounted with endoscope, endoscope is connected sealing with suction stone sheath by the location sealing shroud, be inserted with optical fiber in the endoscope, endoscope passes along inhaling stone sheath lower end rock sucking tube, inhales stone sheath middle part and inhales the stone chamber for spiral, connect negative pressure control valve, vacuum extractor successively by the side draught pipe, the side draught pipe is provided with relief valve.

There is the anti-blocking side opening of the stone of suction at eccentric cavity place, rock sucking tube lower end, prevents to inhale the soma of hurting sb.'s feelings.Endoscope is inserted in the location sealing shroud of inhaling the stone sheath, and the inwall of being close to the rock sucking tube of inhaling the stone sheath stretches out outside the rock sucking tube, forms eccentric structure, the suction stone vestibule of increase, but the big particle diameter rubble of sucking-off improves clear stone effect.Inhaling the stone chamber is the spiral flow line structure, guarantees that the outer wall that rubble is inhaled the stone chamber at centrifugal action lower edge spiral moves.The tangent position that the side draught pipe is inhaled the stone chamber at spiral links to each other, guarantee along spiral inhale rubble that the stone cavity outer wall moves tangentially non-resistance be sucked out, improve and inhale the stone effect.Vacuum extractor is inhaled stone chamber tangent line by the side draught pipe with suction stone sheath spiral and is connected.Relief valve, negative pressure control valve are housed therebetween.Relief valve is tapered hermetically-sealed construction, controls switching automatically by the external and internal pressure difference of side draught pipe, guarantees that inhaling stone system is negative pressure.Negative pressure control valve is hand-operated valve or electromagnetic valve.Vacuum extractor can be regulated the negative-pressure sucking size according to the needs of operation.

The beneficial effects of the utility model are: Wicresoft, rubble are fast, and the clear stone of rubble carries out synchronously, can excrete rubble efficiently, and be low pressure in the renal pelvis, have the shortening operating time, sequela is few, and patient recovers soon, the characteristics that patient's misery is little.

The specific embodiment

With reference to Fig. 1,2,3, the clear stone system of a kind of holmium laser micro-hurt comprises and inhales stone sheath 3, long 100mm～180mm, and inhaling the stone sheath can be that the titanium or titanium alloy rustless steel is processed into or nonmetal macromolecular material molding is made.Be mounted with endoscope 2 in the suction stone sheath, diameter is 2mm～10mm.Endoscope 2 is connected sealing with suction stone sheath 3 by locating sealing shroud 10, is inserted withoptical fiber 1 in the endoscope 2, and optical fiber is low OH silica fibre, and diameter is 100 μ m-1000 μ m.Endoscope 2 passes along inhaling stone sheath lower endrock sucking tube 7, and the diameter of rock sucking tube and location sealing shroud is 2mm～10mm.Inhaling stone sheath 3 middle parts is that spiral is inhaledstone chamber 9, connects negative pressure control valve 5, vacuum extractor 4 successively byside draught pipe 6, and negative pressure control valve is hand-operated valve or electromagnetic valve, and the side draught pipe is provided with relief valve 11.Relief valve is tapered hermetically-sealed construction, controls switching automatically by the external and internal pressure difference of side draught pipe, guarantees that inhaling stone system is negative pressure.There are the anti-blocking side opening of the stone of suction,side opening diameter 1～5mm in eccentric cavity place.

During use, high-powerholmium laser fiber 1 inserts endoscope's 2 service aisles, and endoscope 2 inserts in the location sealing shroud 10 of inhaling stone sheath 3, is pastingrock sucking tube 7 inwalls and is stretching out outside therock sucking tube 7, forms a selenodont suction stone passage with rock sucking tube 7.Selenodont suction stone channel outer wall at distance rock sucking tube lower end 2～20mm has 1～5 anti-plug-hole 8 of suction stone.Side draught pipe 6 is inhaled the 9 tangent lines connection of stone chamber with spiral and is seamlessly transitted, and rubble enters spiral throughrock sucking tube 7 andinhales stone chamber 9, and tangentially non-resistance approachingside suction pipe 6 excretes.
