Abstract
The utility model relates to a radiofrequency catheter to treat the obstructive sleep apnea syndrome. The utility model is provided with two catheters, one ends of the two catheters are connected with each other, the other ends of the two catheters are separated to form a forceps, insulation sheathes are sleeved with the two catheters, and only the inner sides of the top ends are wide open. The utility model solves the problems in the prior art of that, the surgical time is long; because the doctors can not determine how much scope of the sites has been heated, the soft palate and the uvula need to be turned continuously to check the treatment situation, which is easy to damage other normal tissues below the soft palate and the uvula; during the treatment process, other objects are also needed to fix the surgical sites, thus preventing the deviation of the needle-shaped radiofrequency catheter from the treatment position during the heating, therefore, the process is very inconvenient and the operation has certain difficulties. The front end of the utility model can clamp the surgical sites of the soft palate and uvula easily and can bounce backward automatically; while the utility model has small heating area, high efficiency, and high speed and can avoid the damage of other normal tissues. In addition, the utility model has simple and ingenious structure, easy use and high accuracy.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of radiofrequency catheter for the treatment of Obstructive Sleep Apnea.
Background technology
Before the present utility model, for one of method for the treatment of Obstructive Sleep Apnea is with a kind of pin type radiofrequency catheter, needle point one end inserts (as soft palate and the uvula) position that need treat, the other end connects the radio frequency lead, whole needle body seals with insulation sleeve, has only needle point one end that inserts operative site not overlap insulator, opens the radiofrequency generator power supply then, needle point one end heats the soft palate and the uvula of operative site, thereby cures this disease.Its structure as shown in Figure 1.But adopting this pin type radiofrequency catheter is a heating, and speed is slow, soft palate and little by little heating of uvula is needed for a long time; In addition, in the heating process of a point, a point, the position scope that was heated what, the doctor is unclear, must constantly stir soft palate and uvula for this reason, checking the treatment situation, is easy to damage other normal structure below soft palate and the uvula this moment; Also have, also will operative site be fixed with other objects in therapeutic process, to prevent that the pin type radiofrequency catheter departs from treatment position when heating, very inconvenient, operation acquires a certain degree of difficulty.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, design, a kind of tweezer formula radiofrequency catheter of development.
The technical solution of the utility model is:
Tweezer formula radiofrequency catheter, its major technique have been characterised in that two conduits, and an end of two conduits connects, and the other end separately forms tweezers, and socket insulation sleeve on two conduits has only vertical inboard to open wide.
Advantage of the present utility model and effect are that two conduits itself are tweezers, so its front end can clamp soft palate and operation on uvula position easily, need not clamp with other instrument in addition, and can automatically spring open; Because two conduit inner faces open wide, and are facets, there is not the insulation sleeve sealing, be again to be provided with in opposite directions, just in time clamp operative site, therefore be the small size heating, its efficient improves, and speed is fast; Be exactly the position that needs treatment owing to what clamp simultaneously, avoided other normal structure of damage.This utility model is simple in structure, ingenious, and is easy to use, the accuracy height.
Description of drawings
The needle construction sketch map that Fig. 1---prior art is used.
Fig. 2---this utility model structural principle sketch map.
The specific embodiment
As shown in Figure 2, an end of two conduits 1 is interconnection, and the other end opens respectively, forms tweezers, has elasticity, just as tweezers; On two conduits 1, put insulation sleeve 2, have only vertical inboard to open wide, do not have insulation sleeve 2; Its tip designs becomes a plane, is circular arc plane 3; On circular arc plane 3, there is a facet to open wide, is called and opens wide plane 4, do not have insulation sleeve 2 on it; This facet that opens wide promptly has only one side to open wide at two conduits, 1 vertical inner face, and the inner face of two conduits 1 forms setting in opposite directions; In order to raise the efficiency,, open wide facet with 2～3cm also in order to prevent to burn other normal structure
2For good; Two end connection radio-frequency power supply leads 5 that conduit 1 is connected.
During application, do not have the unlimited plane 4 of insulation sleeve 2 just in time to clamp soft palate and uvula position that patient need perform the operation the inboard, top of two conduits 1 (being tweezers), thereby just fixed yet; Open the radiofrequency generator on and off switch then, radio-frequency power supply is delivered to unlimited plane 4 in the circular arc plane 3 by radio-frequency power supply lead 5, and opening wide plane 4 just in time on one, clamp operative site once, from then on radio-frequency current just heats, burns operative site, and soft palate and uvula are dwindled.Heating is closed radio-frequency power supply earlier later, unclamps tweezers again, and the position that another part need be treated is clamped then again because flexible and break away from original operative site automatically in the top of two conduits 1, opens radio-frequency power supply again and heats.In the whole surgery process, because tweezers tightly clamp operative site, can not produce looseningly, just displacement can not appear, all the time operative site is heated to treat.
The scope that this utility model is asked for protection is not limited only to the description of this specific embodiment.
