Description
Technical field
The invention belongs to the field of medical instrument technology more particularly to a kind of bipolar catheter systems of intracavitary therapy.
Background technique
With the continuous development of medical technology, the technology in minimally-invasive treatment field has obtained continuously improving development, increasingly leans on
Nearly noninvasiveization, painlessization, precision；For patient, the treatment more minimally invasive, more accurate, pain is lower, recovery time is shorter
Method is its first choice.
It is that modern medicine is newest and common treatment means using bipolar catheter treatment blood vessel, the intracavitary disease such as bile duct, In
Before minimally invasive catheter treatment system comes out, the mode for generalling use operation treats the intracavitary disease such as blood vessel, bile duct, such as quiet
Arteries and veins varicose disease is exactly removed corresponding vein blood vessel by performing the operation, which damages greatly people, and operating time is long, expense
Height, patient's recovery period is long, and surgical procedure Principle of Pain is big, with the appearance of minimally invasive catheter treatment system, treats blood vessel, bile duct
Just there is larger promotion etc. the technology of intracavitary disease.
But in existing minimally-invasive treatment conduit, there are apparent defects: the treatment conduit of such as monopole is working
Stainless steel tube work head, which needs to paste negative plate, in the process could form current loop；Bipolar treatment conduit, during the work time
Stainless steel tube work head does not need patch negative plate, and electric current is flowed out from a pole stainless steel tube, flows through lesion tissue, then pass through other one
Pole stainless steel tube flows back to, and working end is exposed, and directly with human contact, electric current will flow through human body, inevitably make working end
Adhesion, incrustation are generated with therapentic part, cause Principle of Pain and restores period long and exposed working end in adhesion, incrustation
Conductive capability variation causes therapeutic effect to be deteriorated later, to continual cure, it is necessary to work head be pulled out lesion cavity and carried out
Cleaning, then could continual cure, cause that operating time is long, and surgical effect is unstable.
In the one action period, treatment lesion cavity length is smaller, and work head is easy when successively mobile treatment
There is hollow phenomenon, causes part lesion cavity not treated completely, temperature control is unable in work head therapeutic process, output has
The size of efficiency amount is related with work head electric conductivity, occurs adhesion in the work head course of work at any time, and electric conductivity is deteriorated, so
Electric conductivity is uncontrollable, and the temperature of work head is also just uncontrollable, and the end of existing monopole conduit is stainless steel material, is not had
Elasticity, cannot protrude into that there are the cavities of certain bending degree.
Summary of the invention
To solve the above-mentioned problems, the invention discloses a kind of bipolar catheter system of intracavitary therapy, conduit sheet can be made

To arrange and design.
The present invention is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in FIG. 1 to 3, the bipolar catheter system of a kind of intracavitary therapy, including the output for discharging high-frequency energy
Equipment；It further include catheter body 1, the object placing cavity being connect with catheter body 13 and packet paint heating wire 5；The catheter body 1 includes
First chamber 2；The outer cover of the object placing cavity 3 is equipped with handle 4；The packet paint heating wire 5 is wrapped in the front end of catheter body 1, institute
The outside for stating packet paint heating wire 5 is equipped with the insulating layer 6 that prevents adhesion；Object placing cavity 3 is protruded into one end of the catheter body 1, and is fixed on
The inside of object placing cavity 3；The object placing cavity 3 is detachably connected with handle 4；The packet paint heating wire 5 is protruded into close to one end of handle 4
The inside of first chamber 2 is electrically connected by the first conducting wire 7 with output equipment.
The present invention ensures electric current only in the internal flow of bipolar catheter system, and to prevent adhesion using packet paint heating wire 5
Insulating layer 6 is arranged, and makes electric current without human body, the problems such as generating adhesion so as to avoid therapentic part, form a scab, and meanwhile it is also corresponding
Shorten the recovery period of therapentic part, in addition, also solve because catheter body 1 it is exposed due to caused by conductive capability be deteriorated,
Ensure therapeutic effect of the invention.
In order to preferably using the present invention, it is described packet paint heating wire 5 in it is double and around structure be wrapped in catheter body 1
Front end.It is double and around structure be similar to spring structure, therefore make the present invention can advance in curved cavity when in use；
In some lesion therapeutic process, treatment time is longer, needs manually to carry out multi-pass operation, at this point, the present invention is just as energy
It is enough to advance in curved cavity, it avoids part focal area hollow out and therapeutic effect cannot be reached；In addition, it is double and around
Structure can generate stable fever, and generate heat uniformly, can be improved therapeutic efficiency.
For example, conventional conduit system, the metal tube work head of front end is shorter, only 5mm length, and work a cycle,
The section length ability 5mm for the treatment of；And working end of the invention can be made as 50mm length, and flexible；Work a cycle,
The section length for the treatment of can achieve 50mm, and doctor is without multiple mobile conduit system；Existing conduit system is controlled if necessary
