Disclosure of Invention

The utility model aims to solve the problem of providing a straight pyramid type puncture head with a cutting edge which is extremely good in sharpness and sharper, so that the straight pyramid type puncture head can puncture without resistance and directly penetrate through skin to focus without establishing an endoscope channel or using a puncture needle for puncture; the water outlet has all been seted up to each terminal surface of puncture tool bit, cooperates the peristaltic pump pressure boost, can prevent to break away from the tissue and block up the water outlet and lead to the point portion not to go out water influence operation effect, makes to melt the needle blade portion simultaneously and has the normal saline instillation function, forms the water polo in the focus, wraps up the position of discharging, and the lowering temperature forms plasma operational environment simultaneously, and operating temperature is only 40-70 ℃, reduces the damage to the tissue, can effectively avoid causing the secondary damage to the human body, does not have the wicresoft plasma that causes the postoperative infection and melts the needle.

In order to solve the problem, the utility model provides a wicresoft plasma melts needle, include the handle, connect the power cord at the handle afterbody and connect the plasma cutter subassembly at the handle head, the plasma cutter subassembly includes the puncture tool bit of cutter arbor and tip, the puncture tool bit is pyramid formula structure, puncture tool bit tip part is straight pyramid formula structure, the delivery port has all been seted up to each terminal surface of puncture tool bit, the cutter arbor is bilayer structure, including rust-resistant outer tube, locate rust-resistant needle tubing in the rust-resistant outer tube, be equipped with into water cavity groove A in the rust-resistant needle tubing, into water cavity groove A one end and delivery port intercommunication, rust-resistant needle tubing one end is equipped with into water hose assembly and makes into the intercommunication of water cavity groove A and the chamber groove B that advances in the water hose assembly rather than putting through the hose connector mutually.

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.
