Abstract

The utility model relates to a high frequency electrotome with a protection function, which comprises an electrotome handle and an electrotome electrode. The electrotome electrode is embedded at the front end of the electrotome handle in a coaxial mode. An electrode body of the electrotome electrode, which extends out of the front end of the electrotome handle, is coated with an insulating protective sleeve. In the high frequency electrotome, the insulating protective sleeve with excellent insulating property is sleeved on the electrode body of the electrotome electrode, which extends out of the front end of the electrotome handle, so that tissues at both sides of an electrotome incision can be effectively avoided being scalded due to electric leakage of the electrode body of the electrode, not only a patient is protected, but also the operation difficulty is reduced.

Description

A kind of high frequency electric knife with safeguard function

Technical field

This utility model belongs to technical field of medical instruments, especially relates to a kind of high frequency electric knife with safeguard function.

Background technology

The operation principle of widely used electric knife is when high frequency electric passes through tissue in clinical at present, because the electrical pulse time of each vibration is extremely short, ion is difficult to cause migration, only vibrates in being rich in the body fluid of viscosity, because of heat is given birth in friction.High frequency electric knife utilizes high frequency electric to make by this heat effect of body.

Used electric knife comprises electric knife handle and electric knife electrode now, and described electric knife electrode is inlaid in electric knife handle front end, and TURP control knob and electricity control knob with fixed attention is installed on the electric knife handle.Described electrode mainly is aciculiform and tooth shape electrode, its effective area is very little, and the electric current density in the electrode undertissue is very big, can produce a large amount of heat in a flash, tissue under the electrode is evaporated explosively, split into hemorrhage, narrow and smooth, a not dark several millimeters otch, and also can make the blood coagulation in the blood vessel arrive certain degree of depth, replace ligation, finish otch hemostasis work.

But high frequency electric knife is the surgical instruments of macro-energy output, energy not only concentrates on the incision of electrode tip, energy also has output on the electrode pole body, in case the electrode pole body contacts with the body or the tissue of otch both sides, very easily with its burn, and burn is difficult to discover, and this has not only increased the difficulty that operation brings, and increasing misery to patient, serious malpractice can appear when serious.

By retrieval, do not find device as yet about addressing the above problem.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and can prevent effectively that otch both sides body tissue from being scalded, the electrode preventer of simple in structure, high frequency electric knife that result of use is good.

The purpose of this utility model is achieved in that

A kind of high frequency electric knife with safeguard function; comprise electric knife handle and electric knife electrode; the coaxial electric knife handle front end that is inlaid in of described electric knife electrode is characterized in that: coat on the pole body of the described electric knife electrode that stretches out electric knife handle front end an insulation protective jacket is installed.

And described insulation protective jacket removably is sleeved on the pole body of the electric knife electrode that stretches out electric knife handle front end.

Advantage of the present utility model and good effect are:

1, this high frequency electric knife is set with insulating properties good insulation performance sleeve pipe on the pole body of the electric knife electrode that stretches out electric knife handle front end; can avoid effectively the body tissue of electric knife otch both sides being scalded because of the electric leakage of electrode pole body; both protect patient, reduced operating difficulty again.

2, this high frequency electric knife is cheap for manufacturing cost, and overall structure is simple, and design science is reasonable, and result of use is good.

Description of drawings

Fig. 1 is front view of the present utility model (biopsy cavity marker devices);

Fig. 2 is the A place partial enlarged drawing of Fig. 1.

The specific embodiment

Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.

A kind of high frequency electric knife with safeguard function as shown in Figure 1, comprises electric knife handle 3 and electric knife electrode 1, and the coaxial front end that is inlaid in the electric knife handle of described electrode is equipped with TURP control knob 4 on the electric knife handle and electricity coagulates control knob 5.The structure of electric knife handle and electric knife electrode is a prior art, is not giving unnecessary details.

Innovative point of the present utility model is:

Wrap is equipped with an insulation protective jacket 2 on the pole body of the electric knife electrode that stretches out electric knife handle front end; the shape of this protective sleeve and electrode is corresponding; its length is less than electrode length; expose the electric knife electrode; to guarantee the having electrode of suitable length to undergo surgery, avoid long electrode that the body tissue of operative incision periphery is burnt.In the present embodiment; used insulation protective jacket adopts good insulation preformance and whippy material to make; during use it is sleeved on the pole body of the electric knife electrode that stretches out electric knife handle front end; the time spent can not take off it; and can adjust the length and the size of insulation protective jacket according to different needs, very easy to use flexibly.This insulation protective jacket also can stretch out processing and fabricating one deck insulation protective jacket on the pole body of electric knife electrode of electric knife handle front end in the high frequency electric knife production process, can reach the effect of the otch both sides body tissue that prevents to burn equally.

Claims

1. high frequency electric knife with safeguard function; comprise electric knife handle and electric knife electrode; the coaxial electric knife handle front end that is inlaid in of described electric knife electrode; it is characterized in that: coat on the pole body of the described electric knife electrode that stretches out electric knife handle front end an insulation protective jacket is installed, the shape of this protective sleeve and electrode is corresponding.

2. according to the high frequency electric knife with safeguard function under the claim 1, it is characterized in that: described insulation protective jacket removably is sleeved on the pole body of the electric knife electrode that stretches out electric knife handle front end.
