The technical scheme that this utility model adopts is: a kind of acute critical pancreatitis necrosis region debridement drainage equipment, comprise lumen cannula, expanded casing, clip, hysteroscope sheath, hysteroscope, luminous flushing needle, connecting rod, wherein said expanded casing forms by the stainless-steel pipe that multiple diameter is different is nested successively, to be loaded on described lumen cannula outside for the inside steel pipe socket, described expanded casing has a cylindric periphery, the afterbody of periphery has a coniform extension mouth, for expanding sinus tract, form treatment passage; Described lumen cannula is for supporting operating theater instruments in treatment passage, its inside is fixed with damping mirror sheath sleeve pipe, described luminous flushing needle, hysteroscope sheath and hysteroscope, the afterbody of described luminous flushing needle is by hose connection high-power conveying pump, and the water under high pressure exported by described conveying pump carries out excision of the lesion; Described hysteroscope sheath, hysteroscope form a set of interior cavascope, and described hysteroscope sheath afterbody connects wash tub pipe, for rinsing described hysteroscope camera lens; Described damping mirror sheath sleeve pipe is made up of casing main body and damping sleeve, and wherein said casing main body is stainless steel tube, and internal diameter is slightly larger than described hysteroscope sheath, and described damping sleeve has certain elasticity, its endoporus and described hysteroscope sheath interference fit.

Preferably, described lumen cannula cylindrical is provided with a clip, and the two is connected as one by hand screw; Described clip periphery is provided with a connecting rod, and this connecting rod outer end is fixed on support, for package unit is fixed on support, does not so just need the personnel of special support equipment.

Beneficial effect: what the present invention broke traditions excised by apparatus and remove the mode of slough, strengthening Wicresoft debridement mode, a set of severe pancreatitis necrosis region debridement drainage equipment is proposed, by the water column injecting the suitable pressure of constant temperature, digging type flushing is carried out to slough, and leave sinus tract by waste water drain and suitably process, traditional pancreatitis treatment means are broken, safety, efficient, health, greatly alleviate the misery of patient, also can alleviate quite most pressure to patient economically; Make Operation visual, treat pointed, substantially increase therapeutic effect and cure rate; Simple and reasonable, with strong points, fill up the blank of the Special medical equipment in pancreatitis treatment field.

Accompanying drawing explanation

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is overall structure schematic diagram of the present utility model,

Fig. 2 is the structural representation of interior cavascope and damping mirror sheath sleeve pipe,

Fig. 3 is the structural representation of stove point location apparatus.

Detailed description of the invention

In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

In describing the invention, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the present invention for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.

Before general operation (see Fig. 3), carry out smoothly to enable operation, stove point location to be implemented to operation, in operation, we adopt as the thinner seal wire of in Fig. 1 10 positions, enforcing location of performing the operation is determined after inserting human body, again extension process is carried out to the circular minimal incision * that seal wire 10 is formed, by expansion needle tubing 11 by diameter from little to after carrying out extension process from level to level greatly, a larger sinus tract can be formed at body surface, then insert lumen cannula 1, can be performed the operation by expansion sleeve pipe 2 endoporus during operation.

See Fig. 1, the present invention is mainly made up of lumen cannula 1, expanded casing 2, clip 3, hysteroscope sheath 4, hysteroscope 5, luminous flushing needle 6, connecting rod more than 7 part, wherein expanded casing 2 is set in lumen cannula 1 rear portion, it has a coniform periphery, for expanding sinus tract, form treatment passage; Lumen cannula 1 cylindrical is provided with a clip 3, and the two is connected as one by hand screw, can according to the position of the depth adjustment clip 3 entered in body cavity: namely by unclamping hand screw, being adjusted to suitable position, tightening after determining; Clip 3 periphery is provided with connecting rod 7, and connecting rod 7 outer end is fixed on support (as bend pipe), and another effect of clip 3 is fixed on special stand by connecting rod 7 by this covering device, does not so just need the personnel of special support equipment.

Passage internal fixtion endoscope is treated in acting on of lumen cannula 1, if without this lumen cannula, the degree of freedom of endoscope is unrestricted, can bring certain difficulty to operation.Lumen cannula 1 inside is fixed with damping mirror sheath sleeve pipe, luminous flushing needle 6, hysteroscope sheath 4 and hysteroscope 5, hysteroscope sheath 4, hysteroscope 5 are standard configurations of a set of interior cavascope, can be observed by hysteroscope 5, the external wash tub pipe of hysteroscope sheath 4 afterbody, can guarantee that hysteroscope 5 camera lens front end keeps when needs the visual field (because in pancreas, not having natural passage can supply chamber sem observation) clearly.Luminous flushing needle 6, by hose connection high-power conveying pump, exports suitable pressure by this conveying pump and the water column of constant temperature carries out the excision of pathological tissues, and the temperature of warm water is regulated by attemperating unit.

As shown in Figure 2, damping mirror sheath sleeve pipe is made up of casing main body 12 and damping sleeve 9, wherein casing main body 12 is root 304 stainless steel tubes, internal diameter is slightly larger than hysteroscope sheath 4, can guarantee that hysteroscope sheath 4 freely moves forward and backward and large rocking can not occur in sleeve pipe, damping sleeve 9 can adopt hard gel or nylon etc. to have the materials processing of certain elasticity and rigidity, its endoporus and hysteroscope sheath 4 are interference fit, guarantee a little firmly to make it slide, but hysteroscope 5 deadweight is not enough to overcome its stiction generation relative sliding.Damping mirror sheath sleeve pipe can be guaranteed in operation process, and when unmanned support hysteroscope 5, chamber mirror can not because of deadweight, landing occur or pour patient's cavity, can ensure the safety of patient and equipment simultaneously.

Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
