Preferably, a peristaltic pump connecting pipe is arranged on the water inlet hose assembly and is used for connecting the peristaltic pump.
Preferably, the cutter bar is movably sleeved with a limiting block.
Preferably, the cutter bar is provided with a dial gauge.
Preferably, the puncture tool bit is cast as an integrally formed structure from molybdenum or stainless steel or tungsten-molybdenum alloy.
Preferably, the rustproof outer tube and the rustproof needle tube are both cast by stainless steel into an integrally formed structure
Adopt above-mentioned structure, its beneficial effect lies in:
the utility model discloses the puncture tool bit is pyramid formula structure, puncture tool bit tip part is straight pyramid formula structure, and straight pyramid formula structure can make puncture head blade sharpness splendid, and it is better to compare the puncture head sword puncture effect of current circular arc formula, and the puncture head blade is sharper for straight pyramid formula puncture head sword can puncture the non-resistance little, directly passes the direct focus of skin, need not to establish chamber mirror passageway or use the pjncture needle puncture, sparingly operates the cost and simplifies doctor operating procedure.
The utility model discloses the delivery port has all been seted up to each terminal surface of puncture tool bit, and cooperation peristaltic pump pressure boost can prevent to break away from the tissue and block up the delivery port and lead to the point portion not to go out water influence operation effect, makes simultaneously to melt the needle cutting part and have the normal saline instillation function, forms the water polo in the focus, wraps up the position that discharges, and the lowering temperature forms plasma operational environment simultaneously, and operating temperature only has 40-70 ℃, reduces the damage to the tissue, and effectively gets rid of out water hose assembly, has practiced thrift the cost greatly.
