Description
Technical field
The present invention relates to medical apparatus, particularly relate to a kind of for operating high-frequency electrocoagulation hook.
Background technology
High-frequency electrocoagulation hook is a kind of electrosurgical unit carrying out tissue cutting.When it contact with human body by the high-frequency high-voltage current that active electrode tip produces, tissue is heated, realize the separation of when injected organism tissue and solidify, thus playing the object of cutting and stopping blooding.
Existing high-frequency electrocoagulation hook adopts gib head first to separate needing cutting or solidifying disconnected organizing, and provoke, be energized again to reach cutting or solidifying disconnected object, but at neural or that blood vessel is comparatively fine and close tissue, the front of gib head cannot will cut and organize and non-cutting separate tissue, therefore easily touch nerve or blood vessel when being energized, cause the accidental injury to neural or blood vessel.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, easy to operate, the one of operation safety is for operating high-frequency electrocoagulation hook.
For achieving the above object, technical scheme of the present invention is:
A kind of for operating high-frequency electrocoagulation hook, comprise the housing of insulation, electric pole is provided with along its length in described housing, one end that electric pole extends housing is provided with the gib head of upwards bending, and the other end of housing is provided with electrode contact, and electrode contact is electrically connected with electric pole, sliding cavity is provided with along its length in described housing, slide in described sliding cavity and be provided with pull bar, described pull bar is fixed with heater near one end of gib head, and the corresponding gib head of described heater is arranged.
Described high-frequency electrocoagulation hook also comprises suction pipe, and described suction pipe is arranged in sliding cavity, and one end of suction pipe extends to housing one end near gib head, and the other end of suction pipe is connected with aspirator and flushometer respectively by three-way valve.The smog that operation process produces can be aspirated by suction pipe, or the tissue after cutting is cleaned.
Described gib head inside is provided with temperature sensor.Temperature sensor, for monitoring the temperature of gib head, ensures that the temperature of gib head is in safety range.
Described housing is provided with the push-pull configuration driving pull bar to slide in sliding cavity.
Described push-pull mechanism comprises push-and-pull block, and the one end near electrode contact on described housing is provided with draw-in groove, and described push-and-pull block is set in draw-in groove, and is fixedly connected with electric pole.
Described heater is resistance heater, ceramic heating element, Tao Jingfa hot body, Si-Mo rod heater, siliconit heater or Lanthanum Chromite heater.
The cut-out mode organized between described heater and gib head can adopt the mode of microwave, argon-gas knife, radio frequency knife, ultrasound wave, high frequency electric, plasma or laser to heat rear cut-out and cut and organize.
When the present invention is applied to the comparatively fine and close tissue cutting of nerve or blood vessel and hemostasis, first opened needing cutting or solidifying disconnected separate tissue by gib head, and provoke, again heater is pushed to the tissue touching and provoke to gib head direction, under being organized in the effect of heater heating, realize cutting and the hemostasis of tissue.In said process, be not to be energized the cutting and hemostasis that realize tissue by gib head, thus the temperature of gib head is lower, can not cause accidental injury to neural under gib head or blood vessel.In addition, in the neural or unsound place of blood vessel, the present invention also can according to existing method, to be energized the cutting and hemostasis that realize tissue by gib head.
Structure of the present invention is simple, operates simple and easy, and can heater or gib head be selected to cut tissue for different situations or stop blooding, in use procedure, safety be higher, and purposes is wider.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is a kind of sectional view for operating high-frequency electrocoagulation hook of the present invention;
Fig. 2 is A-A sectional view in Fig. 1.
Detailed description of the invention
As shown in Figure 1 or 2, the present invention's one is used for operating high-frequency electrocoagulation hook, comprise the housing 1 of insulation, electric pole 2 is provided with along its length in described housing 1, one end that electric pole 2 extends housing 1 is provided with the gib head 3 of upwards bending, the other end of housing 1 is provided with electrode contact 4, electrode contact 4 is electrically connected with electric pole 2, sliding cavity 5 is provided with along its length in described housing 1, slide in described sliding cavity 5 and be provided with pull bar 6, described pull bar 6 is fixed with heater 7 near one end of gib head 3, and the corresponding gib head 3 of described heater 7 is arranged.
Described high-frequency electrocoagulation hook also comprises suction pipe 8, described suction pipe 8 is arranged in sliding cavity 5, one end of suction pipe 8 extends to housing 1 one end near gib head 3, and the other end of suction pipe 8 is connected with aspirator (not shown) and flushometer (not shown) respectively by three-way valve (not shown).
Described gib head 3 inside is provided with temperature sensor 9.
Described housing 1 is provided with the push-pull configuration driving pull bar 6 to slide in sliding cavity 5.
Described push-pull mechanism comprises push-and-pull block 10, and the one end near electrode contact 4 on described housing 1 is provided with draw-in groove 11, and described push-and-pull block 10 is set in draw-in groove 11, and is fixedly connected with electric pole 2.
Described heater 7 is resistance heater, ceramic heating element, Tao Jingfa hot body, Si-Mo rod heater, siliconit heater or Lanthanum Chromite heater etc.
The cut-out mode organized between described heater 7 and gib head 3 can adopt the mode of microwave, argon-gas knife, radio frequency knife, ultrasound wave, high frequency electric, plasma or laser to heat rear cut-out and cut and organize.
Heater 7 in the present invention is connected with external control main frame, and during work, main control system controls the temperature of heater 7 in 200-300 DEG C.
When the present invention is applied to the comparatively fine and close tissue cutting of nerve or blood vessel and hemostasis, first opened needing cutting or solidifying disconnected separate tissue by gib head 3, and provoke, again heater 7 is pushed to gib head 3 direction the tissue touching and provoke, under being organized in the effect of heater 7 heating, realize cutting and the hemostasis of tissue.But, under the repeated action of heater 7, unavoidable because conduction of heat makes gib head 3 heat up, when gib head 3 is warming up to 200-300 DEG C, also can cause accidental injury to neural or blood vessel.Therefore, the present invention monitors the temperature of gib head 3 by temperature sensor 9, ensures that gib head 3 is performed the operation under safe temperature.
Certainly, in neural or the unsound place of blood vessel, the present invention also according to existing method, can realize cutting and the hemostasis of tissue by gib head 3 energising.
In addition, the smog that the present invention can also be realized operation process produces by suction pipe 8 aspirates, or cleans the tissue after cutting.
