Description

Radio frequency ablation device for rhinitis treatment

Technical Field

The utility model relates to the field of medical equipment, in particular to a radio frequency ablation device for treating rhinitis.

Background

Rhinitis is a common chronic rhinopathy in clinic, affects 10-20% of the population worldwide, becomes a global health problem, and has a tendency of increasing year by year in China. The disease is chronic noninfectious inflammation of nasal mucosa mainly mediated by allergen-specific immunoglobulin after specific individuals are exposed to allergens, and the disease becomes a main chronic inflammatory disease of respiratory tract in recent years;

the treatment principle of rhinitis is 'prevention and treatment combination and four-in-one', and comprises environmental control, medicament treatment, immunotherapy and health education; allergic rhinitis is clinically treated by taking allergen contact prevention, operation treatment, drug treatment and immunotherapy as main treatment means; surgical treatment is becoming increasingly important as an adjunct to the conventional treatment of allergic rhinitis;

it is therefore desirable to design a radiofrequency ablator for the treatment of rhinitis.

SUMMERY OF THE UTILITY MODEL

The utility model provides a radio frequency ablation device for treating rhinitis, which can solve the problems pointed out in the background technology.

A radio frequency ablator for rhinitis treatment, comprising:

a host;

the handle is detachably arranged on the host through a connecting line;

the handle is provided with a connecting rod, the end part of the connecting rod is provided with a treatment head, one side of the treatment head is provided with a single-pole head, and a measurement and control unit is further arranged in the connecting rod.

Preferably, the host computer includes the casing and sets up the display screen on the casing, it has an upper cover to articulate on the casing, be provided with one in the casing and be used for holding the interior box of handle.

Preferably, the measurement and control unit is an optical fiber temperature sensor.

Preferably, the connecting rod is further provided with a developing ring.

Preferably, a PCB electrically connected with the measurement and control unit and the connecting wire is arranged in the handle.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a be equipped with interior box in the host computer, be convenient for accomodate the handle to prevent that the handle from receiving the pollution when not using, optic fibre temperature sensor is used for the real-time supervision temperature, takes place with the condition of avoiding output too high, and the development ring is convenient for show that electrode treatment head can accurately reach treatment area.

Description of reference numerals:

the device comprises a main machine 1, a handle 2, a connecting wire 3, a connecting rod 4, a treatment head 5, a single-pole head 6, an optical fiber temperature sensor 7, a display screen 8, an upper cover 9, an inner box 10, a developing ring 11 and a PCB 12.

Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

As shown in fig. 1 to 5, an embodiment of the present invention provides a radio frequency ablation device for treating rhinitis, including:

the main machine 1, an electric generator and a computer unit are arranged in the main machine 1;

the handle 2 is detachably arranged on the host 1 through a connecting wire 3;

both the electrical generator and the computer unit are prior art and are not described herein in detail;

the electric generator is connected with a connecting wire 3, and an interface matched with a plug of the connecting wire 3 is arranged on the host 1;

the handle 2 is provided with a connecting rod 4, the end part of the connecting rod 4 is provided with a treatment head 5, one side of the treatment head 5 is provided with a single-pole head 6, and the inside of the connecting rod 4 is also provided with a measurement and control unit which automatically adjusts the output power of the radio frequency ablation by monitoring the change of parameters such as impedance, temperature and the like of the tumor tissue, so that the tumor tissue can rapidly generate coagulation necrosis in a large range;

when radio frequency current flows through human tissues, positive and negative ions in cells move rapidly due to rapid change of an electromagnetic field, and then temperature of a diseased part is raised due to friction among the positive and negative ions and between the positive and negative ions and other molecules, ions and the like in the cells, so that water inside and outside the cells is evaporated, dried, shrunk and shed to cause aseptic necrosis, thereby achieving the purpose of treatment;

the main machine 1 comprises a shell and a display screen 8 arranged on the shell, an upper cover 9 is hinged on the shell, and an inner box 10 for accommodating the handle 2 is arranged in the shell;

a PCB 12 electrically connected with the measurement and control unit and the connecting line 3 is arranged in the handle 2;

the measurement and control unit is an optical fiber temperature sensor 7.

The connecting rod 4 is also provided with a developing ring 11;

when not in use, the inner box 10 can be used for containing the treatment handle 2, in the use process, the treatment head 5 is in contact with the tissue causing rhinitis blockage in the nasal cavity, the radio frequency energy ablates the tissue, the optical fiber temperature sensor 7 senses the temperature, and the developing ring 11 is used for displaying the positions of the electrode treatment head and the target treatment area.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
