Use technique scheme, the work use principle of the present invention is: determine the distance of distance center of turntable at the injection of jet orifice according to lipoma or fibromatous size, select a jet orifice, other jet orifice is blocked, the process blocking jet orifice is: rotate handwheel, driving depression bar moves down, and jet orifice is blocked by the pressure pad of depression bar lower end.When carrying out excision lipoma or fibroma, first pass through the center of cross laser indicator localized resection, the hand-held handle of doctor, open high-pressure hydraulic pump and drive motor, distilled water supercharging is entered the hollow rotary shaft in rotatory sealing attachment means by high-pressure hydraulic pump through high-pressure water pipe, again through Hollow Transmission Shafts, finally enter in rotating disk, by the jet orifice ejection water under high pressure regulated；Simultaneously driving motor, by driving gear, rotational action is passed to driven gear, driven gear drives Hollow Transmission Shafts to rotate, and is sealedly and fixedly connected by jointing clip between Hollow Transmission Shafts and hollow rotary shaft, realizes the rotation of rotating disk while sealing.Thus rapidly lipoma or fibroma can be excised in cortex, re-use tweezers and lipoma or fibroma are pressed from both sides out.The external diameter of driven gear, more than the external diameter of driving gear, so can reduce the rotary speed of rotating disk.
The operation principle of the rotatory sealing attachment means in the present invention is: water under high pressure enters into the blasthole of top connection through high-pressure water pipe, then enters in Hollow Transmission Shafts in sequentially passing through through hole, pilot hole, hollow rotary shaft；Owing to through hole internal diameter is less than blasthole internal diameter, under the effect of High-Pressure Water, gland lower end is to filling sealing ring extruding, and extruding force is delivered on the second O, and the second O is deformed thus plays sealing function, and the second O is made by special substance；Make filling sealing ring and hollow rotary shaft tight fit, High-Pressure Water flows out through hollow rotary shaft, hollow rotary shaft uses special process to process with filling the sealing ring place of cooperation, in order to reduce the frictional force of itself and filling sealing ring, fills sealing ring and uses special substance to be made；Hollow rotary shaft is arranged in sleeve pipe by the 3rd bearing and the 4th bearing, and hollow rotary shaft can rotate under external force；And the 3rd bearing and the 4th bearing in use need lubrication, the lubrication hole oil addition being provided with by sleeve pipe can lubricate bearing, and the first O and the second sealing ring are used for stopping oil leakage；Bearing trim ring lower surface compresses the 3rd bearing, and bearing trim ring endoporus is slidably matched with hollow rotary shaft, and the support set at bearing trim ring top is used for supporting filling sealing ring, and bearing trim ring uses special substance to be made, to reduce the frictional force of itself and hollow rotary shaft.
When leaking occurs in the detachable logical watertight construction in rotatory sealing attachment means, i.e. filling sealing ring and the second O damages, water under high pressure can enter into permeable intracavity along hollow rotary shaft surface, and flows out sleeve pipe by water-permeable passage, cannelure and weeper；Water under high pressure or penetrate into bearing trim ring upper surface along pilot hole inwall, then it is flowed into weeper through internal surface of sleeve pipe.If weeper water outlet, it is necessary to fasten silk braid on dismounting is lower, filling sealing ring and the second O are replaced.First O plays and prevents water from entering in the 3rd bearing and the 4th bearing.
The effect of critical piece of the present invention and feature:
Drive motor: for the powered rotation of rotating disk, final drive rotating disk rotates and realizes circumgyration incision；
Rotatory sealing attachment means: realize the connection between fixing high-pressure water pipe and the Hollow Transmission Shafts of high speed rotating, and play good sealing function, meets rotating and the requirement sealed under high pressure conditions；
High-pressure water pipe: the flow pipe of High-Pressure Water；
Hollow rotary shaft: can rotate in revolving joint and and revolving joint between excellent sealing, it is achieved High-Pressure Water rotation docking；
Jointing clip: play coaxial connection fixation hollow rotary shaft and the effect of Hollow Transmission Shafts；
Rotating disk: be used for installing manual sealing adjustment mechanism, and make High-Pressure Water disperse, by driving the drive of motor, carry out rotating jet cutting operation；
By turning pressure cap, pressure cap pushes up downwards pressure gland, gland lower surface is pressed down against soft sealed packing (soft sealed packing, it is commonly called as pureed soft packing, it it is the airtight and watertight padding of a kind of new synthesis of polymer material without asbestos, outward appearance such as clay shape has special plasticity), depression bar outer surface is sealed by soft sealed packing, it is to avoid water under high pressure is revealed at this；
Pressure pad lower surface is the spherical structure upwards caved in, and can improve the sealing effectiveness to jet orifice；
Gland lower surface is the up-small and down-big concave structure in cone, so when being pressed down against soft sealed packing, to the extruding force of soft sealed packing towards depression bar, fully improves sealing effectiveness.
Owing to needing to bear the high pressure of water under high pressure in rotating disk, this is accomplished by sufficiently sealing, therefore arrange on the first seal box and seal, with first, the first sealing structure that regulating block is slidably matched, it is respectively provided with the first corrosion protection sealing gasket coordinated with rotating disk inner bottom surface and guiding cheekn slipper seal at the first sealing regulating block lower surface and the first guide groove inwall, second seal box is arranged and seals, with second, the second sealing structure that regulating block is slidably matched, regulating block lower surface and the second guide groove inwall this second corrosion protection sealing gasket coordinated with rotating disk inner bottom surface and guiding cheekn slipper seal respectively is sealed second.Water under high pressure will not be entered in thus can ensure that the first seal box and the second seal box.
In sum, the present invention is novel in design, compact conformation, easy to operate, good airproof performance, safe and reliable, the radius of jet can be adjusted according to lipoma or fibromatous size, disposably lipoma or fibroma are excised, operating time is greatly shortened, and need not move in operation process, and the doctor being suitable for different experience operates.
