Abstract
The utility model discloses a low-temperature plasma treatment knife head with front and rear electrodes, wherein a needle head at the front end is mounted on a knife head handle through a knife bar, a wire is arranged inside the knife bar and used for providing electrodes to the needle head, the needle head is cone-shaped and connected with the wire inside the knife bar, a metal tube is arranged outside the wire, an insulating layer is arranged between the metal tube and the wire, the metal tube is connected with another wire, an enveloping layer is arranged outside the metal tube in a way that the front end of the metal tube is exposed, the distance from the exposed front end of the metal tube to the needle head ranges from 2 mm to 5 mm, and the metal tube and the needle head form two poles of a plasma body. Since the front end of the knife head has the needle tip-like conical shape, the low-temperature plasma treatment knife head is very suitable for drilling surgeries.
Description
Affiliated technical field
This utility model relates to the surgical operation Medical Instruments, particularly a kind of radio frequency plasma operation cutter head.
Background technology
Operative treatment is that a kind of risk is than higher medical scheme, wherein amount of bleeding greatly and hemorrhage back blood hindered the doctor to observe sight line be exactly to produce dangerous one side to implementing operative site, the present utilization of " plasma " technology on medical operating, operation risk obtains very big reduction, " plasma "---promptly, produce plasma with the electric energy exciting media, the high speed charged particle in the plasma directly interrupts molecular link, makes protein etc. organize cracking to be vaporized into OH
-, low-molecular-weight gas such as H2, O2, CO2, N2 and methane, thereby realize Wicresoft's effect, and can when undergoing surgery, implement hemostasis to operation face, the advantageous effect of " plasma " technology in clinical treatment be the trend of medical development just.
Plasma technique is the electrode that produce to need with therapeutic instrument, is transported to then to realize on the operation cutter head, and cutter head promptly is equivalent to the scalpel of general surgery, is used to cut.
But its form of present cutter head is single, does not satisfy the enforcement needs of some operation.When implementing different operations, needed cutter head structure should be different.
The utility model content
In order to overcome above problem, this utility model provides utmost point treatment cutter head before and after the low-temperature plasma, is convenient to very much operation on the operative treatment aspect being used to punch, melt and implements.
This utility model is following structure:
It is installed on the cutter head handle 1 by knife bar 2 by the syringe needle 5 of front end, promising syringe needle 5 also is set in the knife bar 2 provides the lead 6 of electrode, syringe needle 5 is a cone, link to each other with the lead in the knife bar 2, lead 6 is outside equipped with metal tube 3, be provided with insulating barrier 4 at metal tube 3 and 6 in lead, also be provided with big envelope layer 7 and metal tube 3 bare front end outside metal tube 3, metal tube bare front end end and syringe needle 5 are at a distance of 2-5mm.Lead 6 is a silver jacketed wire.Metal tube is the stainless steel metal pipe.Insulating barrier 4 and big envelope layer 7 are heat-shrink tube.
Cutter head front end of the present utility model is that needle point is cone-shaped, is being highly suitable for implementing the operation of punching class.
Description of drawings
The johning knot composition of Fig. 1 cutter head and handle;
The structure chart of Fig. 2 this utility model cutter head.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
Cutter head handle 1 is provided with switch, the jack-plug socket and the therapeutic instrument of handle 1 rear end join, therapeutic instrument is respectively the electrode of metal tube 3 and syringe needle 5 input different potentials, make 3 of syringe needle 5 and metal tubes produce potential difference, form plasma, be used for that the position is implemented in operation and melt, hemostasis simultaneously.Syringe needle is a cone shape, and front end forms tip-like, behind syringe needle aligning operation enforcement position, and the class of can punching operation.
In conjunction with the accompanying drawings the specific embodiment of the present utility model has been carried out exemplary description above, obviously this utility model is not limited thereto, and the various remodeling that carry out in this utility model scope all do not exceed protection domain of the present utility model.
