Abstract

The utility model provides a medical high-frequency surgical knife, comprising a knife handle which is molded by injecting with organic glass or other engineering plastics, a push-button switch which is installed on the knife handle, a semicircle electrode at the front end of the handle, and a cable at the end of the handle. The conducting wires which are connected with the push-button switch and the electrode are sealed in the handle. The utility model has the advantages of good durability, small size, portable agility, free control through the push-button switch which is arranged on the knife handle, high frequency current generator working, etc. The utility model is the substitute product of the currently existing medical high-frequency surgical knife.

Description

Medical high-frequency surgical knife

This utility model relates to a kind of medical apparatus and instruments, especially a kind of medical high frequency electric knife.

At present, the scalpel that hospital uses for patient operates is that the sharp sword by blade cuts, the edge of a knife of cutting, because muscular tissue and blood vessel are subjected to wound and can bleed profusely, in bigger operation, because of the edge of a knife is bled too much, will transfuse blood to patient, in some operation as during encephalopathy performs the operation, a spot of bleeding also is danger close, can cause various sequela to patient in addition.Just can avoid wound to bleed in a large number and adopt high frequency electric knife to operate, when cutting muscular tissue, can seal blood capillary, can also prevent the courses of infection of the edge of a knife.Existing high frequency electric knife, in use very inconvenient because unreasonable structure is not with gauge tap again, influenced the quality of operation, and made the operating time lengthening.

The purpose of this utility model provides a kind of light durable, and the high frequency electric knife of belt switch control.

The purpose of this utility model realizes in the following manner, medical high frequency electric knife is by lucite or Other Engineering is plastic injection-moulded forms, the control knob switch is installed on the handle of a knife, and two semicircular electrodes are installed the front end of handle of a knife, and the lead that connects press button and electrode all is locked among the handle.Draw from the end of handle of a knife with the cable that lead connects.Hold handle of a knife and press press button and just can start high-frequency current generator, high frequency electric discharges at two interpolars, and the patient is implemented operation.

Figure of description 1 is the structural representation of medical high frequency electric knife of the present utility model.

Figure of description 2 is the sketch map of termination electrode before the medical high frequency electric knife of the present utility model.

With reference to Figure of description the utility model is described in detail.

Medical high frequency electric knife of the present utility model is made up of handle of a knife (1), press button (2), electrode (4) and cable (3), press button (2) is installed on the handle of a knife (1), electrode (4) is installed in the front end of handle of a knife (1), and cable (3) is drawn from the end of handle of a knife (1).

Handle of a knife (1) adopts lucite or Other Engineering plastics single injection-molded, and press button (2) is installed on the handle of a knife (1), and the lead that connects press button (2) and electrode (4) all is locked among the handle of a knife (1).Cable (3) is drawn with high-frequency current generator from the end of handle of a knife (1) and is connected.

For the ease of implementing operation, at the front end of handle of a knife, curved one 90 °-150 ° angle of bend, two semicircle sheet metal electrodes (4) are fixed on the front end of handle of a knife (1).

Embodiment:

The cable and the high-frequency current generator of medical high frequency electric knife end of the present utility model are connected.When implementing operation, pressing press button just starts high-frequency current generator and sends into high frequency electric and delivered on two semicircular electrodes by lead, skin or muscular tissue are cut open under the effect of current/voltage, because the hyperpyrexia that electric current produces, can seal blood capillary, the carrying out of the influence operation of avoiding bleeding too much.

Medical high frequency electric knife of the present utility model, it is little to have a volume, and light and flexible is sturdy and durable, and the characteristics such as shock-resistant proof voltage are the substitute products of existing electric knife.

Claims

1, a kind of medical high frequency electric knife comprises handle of a knife, press button, cable and electrode, it is characterized in that press button is installed on the handle of a knife, and electrode is installed in the front end of handle of a knife, and cable is drawn from the handle of a knife end.

2, electric knife according to claim 1, the electrode that it is characterized in that the handle of a knife front end are two semicircle sheet metals.

3, electric knife according to claim 1 is characterized in that handle is by lucite or Other Engineering is plastic injection-moulded to form that the lead that connects press button and electrode is locked among the handle.

4, electric knife according to claim 1 is characterized in that the front end of handle of a knife one 90 °-150 ° angle of bend being arranged.
