Abstract
The utility model relates to a low temperature plasma cervical vertebra surgical knife, characterized in that the surgical knife comprises a main machine, a controller, a knife body and a knife head arranged at the end of the knife body and a platinum electrode is mounted on the top of the knife head and the knife body is multi-layer structure. The low temperature plasma cervical vertebra surgical knife has features of reasonable structure design, precision and compactness, accuracy, safety and convenience and is completely suitable for the cervical vertebra excision surgery.
Description
Technical field
This utility model belongs to the medical plasma operating theater instruments, is specifically related to a kind of low-temperature plasma cervical operation cutter of suitable cervical operation.
Background technology
The ultimate principle of low-temperature plasma scalpel is a cryogenic ablation, promptly utilizes the high-energy characteristic characteristic of 100KHz rf electric field, makes between electrode and tissue and forms the plasma thin layer.After this thin layer intermediate ion is quickened by electric field energy delivery given tissue and at low temperatures (40-70 ℃) open iuntercellular molecule associative key, thereby the excision of organizing, melt, stop blooding, alleviate the damage of tissue and patient's misery greatly and shorten recovery period.
But existing low-temperature plasma scalpel has universality, but because the numerous and jumbled and physiological main effect of neck dissection structure makes operating difficulty big, complication takes place very easily.
The utility model content
This utility model provides a kind of reasonable in design, accurate small and exquisite low-temperature plasma cervical operation cutter, and it can be fit to the characteristics of cervical intervertebral disk resection operation fully, accurate, safety, convenience.
The technical solution adopted in the utility model is as follows:
A kind of low-temperature plasma cervical operation cutter, it is characterized in that described scalpel comprises a main frame, controller, cutter hub and is positioned at the cutter head of cutter hub end, described main frame is a 100KHz electric field generator, and the top of cutter head is equiped with platinum electrode, and cutter hub is sheathed multiple structure.
In the specific embodiment, an insulating barrier is put in described cutter hub overcoat installing near platinum electrode, and on the bearing of trend of cutter hub, a stainless steel layer is put in this insulating barrier overcoat installing at this insulating barrier.
In one embodiment, on the bearing of trend of cutter hub, second insulating barrier is put in this stainless steel layer overcoat installing at described stainless steel layer.
In another embodiment, at described second insulating barrier on the bearing of trend of cutter hub, this second insulating barrier
Be outside equipped with second stainless steel layer, this second stainless steel layer outsourcing covers puts the 3rd insulating barrier.
Again in the embodiment, the invention provides a kind of low-temperature plasma cervical operation cutter, it is characterized in that described scalpel comprises a cutter hub and the cutter head that is positioned at the cutter hub end, described main frame is a 100KHz electric field generator, the top of cutter head is equiped with the droplet-shaped tungsten electrode, and cutter hub is sheathed multiple structure.
The structure of the cutter body that this low-temperature plasma cervical operation cutter adopts circular layer to be provided with, between two-layer stainless steel layer and the outside is provided with insulating barrier respectively, each layer ecto-entad, to the indentation successively of cutter head bearing of trend, cutter head can adopt platinum electrode or tungsten electrode by cutter hub.Electrode is positioned at the top of cutter head, and whole cutter hub adopts straight-bar structure or 10 degree angle structures, is convenient to the operation of location and scanning treatment.
This low-temperature plasma cervical operation cutter is the small and exquisite shell operation tool of disposable precision, and it is compared with microwave, and is radiationless, and temperature is lower, and therapeutic effect is better; Compare with radio frequency, frequency, temperature are lower, and it is more stable to work; Compare with laser, can cut by arc, no luminous reflectance, the periphery damage is little.
The beneficial effects of the utility model are that this low-temperature plasma cervical operation knife structure is reasonable in design, and accurate small and exquisite, it can be fit to the characteristics of cervical intervertebral disk resection operation fully, accurate, safety, convenience.
Below in conjunction with the drawings and specific embodiments this utility model is further elaborated.
Description of drawings
Fig. 1 is cutter hub and a cutter head structural representation partly in this utility model specific embodiment.
Fig. 2 is that the structure of this scalpel in this utility model specific embodiment is formed sketch map.
The specific embodiment
As depicted in figs. 1 and 2, this low-temperature plasma cervical operation cutter has a main frame 60, controller 70, cutter hub 80 and is positioned at the cutter head of cutter hub end, and cutter hub all is connected with main frame with controller, realizes control to cutter hub and cutter head by controller by main frame.The top of cutter head is equiped with platinum electrode 50, this platinum electrode also can adopt the droplet-shaped tungsten electrode to replace, cutter hub is sheathed multiple structure, the structure of the cutter body that it adopts circular layer to be provided with, between two-layer stainless steel layer and the outside is provided with insulating barrier respectively, except that outermost insulating barrier and second stainless steel layer in it are equal to, each layer ecto-entad, by cutter hub to the indentation successively of cutter head bearing of trend, an insulating barrier 40 is put in cutter hub overcoat installing near platinum electrode, on the bearing of trend of cutter hub, a stainless steel layer 30 is put in this insulating barrier overcoat installing at this insulating barrier.Stainless steel layer is on the bearing of trend of cutter hub, and second insulating barrier 20 is put in this stainless steel layer overcoat installing.On the bearing of trend of cutter hub, this second insulating barrier is outside equipped with second stainless steel layer 10 at second insulating barrier, and outer can the coating of this second stainless steel layer is provided with the 3rd insulating barrier.
