Technical field
This utility model relates to a kind of electric coagulation aspirator, the rotatable electric coagulation suction apparatus for paranasal sinus of particularly a kind of handle, and it mainly is applicable in the ent surgery, belongs to medical apparatus and instruments.
Background technology
In the prior art, operation mainly comprises main body and joint with suction pump, and this main body and joint are hollow structure; The rear end of this main body is adjacent with the front end of joint, and main body wherein is to be fixedly connected with joint, can't be movable; This just makes existing suction pump when operation; Attract if suction catheter need turn over angle, must related joint with attract silica gel tube etc. to run up, operation is used inadequately and is made things convenient for.
The utility model content
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of rotatable electric coagulation suction apparatus for paranasal sinus of handle of reasonable in design is provided.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: the rotatable electric coagulation suction apparatus for paranasal sinus of this handle comprises suction catheter, electrode, electriocoagulator, main body and joint; Electrode is fixed on the main body; Main body and joint are adjacent, and suction catheter and main body all are coated with insulating barrier outward, and electriocoagulator is fixed on an end of suction catheter; It is characterized in that: described joint is a swivel joint, flexibly connects between this swivel joint and the main body; Also be provided with a hollow connecting member, this connector is connected with main body, and this connector is positioned at swivel joint; Described main body and swivel joint are through the sealing member sealing; Described main body, swivel joint, connector and sealing member are formed centrally a passage in them on same axis.
The described connector of this utility model be connected with main body be meant connector fuse with main body weld or be threaded or rabbet in a kind of.
One end of the said connector of this utility model is connected with a convexity, the external diameter of this convexity protrusion connector.
Its cross sectional shape of the described connector of this utility model is circular.
The described sealing member of this utility model is a sealing ring, and described sealing ring is positioned at seal groove.
The described suction catheter of this utility model is a bend pipe.
This utility model compared with prior art has the following advantages and effect: reasonable in design, simple, can relatively rotate between swivel joint and the main body, and it is easy to use and reliable to perform the operation; Suction catheter or operation head can arbitrarily rotate as required, can related swivel joint with attract silica gel tube etc. to run up, guaranteed carrying out smoothly of operation.

The specific embodiment
Embodiment 1: referring to Fig. 1-Fig. 3; Present embodiment comprises suction catheter 8, electrode 9, electriocoagulator 10, main body 1, swivel joint 2, sealing member and connector 4; Sealing member wherein is a sealing ring 3; Connector 4 is the attaching nut, and described sealing ring 3 is positioned at seal groove 21, and seal groove 21 is opened on swivel joint 2; Electrode 9 is fixed on the main body 1, and main body 1 is adjacent with swivel joint 2, all is coated with insulating barrier outside suction catheter 8 and the main body 1, and electriocoagulator 10 is fixed on an end of suction catheter 8.
The front end of the rear end of this utility model main body 1 and swivel joint 2 is adjacent, is flexible connection between described swivel joint 2 and the main body 1; Main body 1, swivel joint 2, sealing ring 3 and connector 4 are hollow structure, and connector 4 is between main body 1 and swivel joint 2, and through these connector 4 flexible connection main bodys 1 and swivel joint 2, connector 4 its cross sectional shapes are circular; Described main body 1 seals through sealing ring 3 with swivel joint 2; Simultaneously, main body 1, swivel joint 2, connector 4 and sealing ring 3 are formed centrally a passage 7 in them on same axis 6.
The connector 4 of this utility model be connected with main body 1 be meant connector 4 fuse with main body 1 weld or be threaded or rabbet in a kind of; In the present embodiment, connector 4 is threaded with main body 1 after penetrating sealing ring 3 and swivel joint 2.
One end of the said connector 4 of this utility model is connected with a convexity, the external diameter of this convexity protrusion connector 4; In the present embodiment, this convexity is attaching nut protruding 41.
The suction catheter 8 of this utility model is a bend pipe; In the present embodiment, suction catheter 8 is at head-bent.
During use, handle 1 can weld with attracting body 8; Various operating theater instruments can be passed through from passage 7, and when suction catheter 8 need turn over an angle attraction, as long as rotate main body 1, swivel joint 2 and attraction silica gel tube etc. can keep original position, the carrying out of convenient operation at this moment.
Said among this paper " swivel joint 2 with main body 1 between flexibly connect " can be: swivel joint 2 directly is not connected with main body 1, but swivel joint 2 passes through connector 4 and main body 1 flexible connection; In a word, must be active between swivel joint 2 and the main body 1.
Embodiment 2: referring to Fig. 4, the structure of present embodiment and embodiment 1 is basic identical with use, and just suction catheter 8 is crooked at postmedian.
Below only be a specific embodiment described in this description, allly conceive equivalence or the simple change that described structure, characteristic and material are done, include in the protection domain of this utility model patent according to this utility model patent.
