Abstract

The utility model relates to an electrode catheter for a medical tissue condenser. The utility model is characterized in that a tubule is internally provided with a hollow pipe which is provided with a probe on an end. The probe is provided with a small hole. The back portion of the probe is connected with the top portion of the tubule. A floating ball is arranged inside the probe with a large portion inside the probe and a small portion outside. The back portion of the probe is contacted with a spring which is connected with the probe or the tubule on other end. The probe reaches the surface of a wound. The tissue and a normal saline are connected with two poles of the radio-frequency generator, wherein the normal saline is communicated with the hollow pipe inside the tubule. The utility model solves the problem of the eschar bleeding of the wound surface because the normal saline has the characteristics of conducting and cooling, reduces the treatment span and the patient suffering and has the advantages of simple structure and convenient usage.

Description

Coagulation of tissues device electrode catheter

Technical field

This utility model relates to a kind of medical equipment, particularly a kind of apparatus of coagulation of tissues.

Background technology

Before this utility model is made, the surgeon cut and organize or electric coagulation hemostasis aspect, adopt Single-pole electric knife usually, promptly a termination electrode is connected with tissue, and the other end is exactly an electric knife head, and electric knife head walks to the tissue energising that needs cutting or hemostasis place, emit energy organizing the contact position electric knife, can make temperature up to 350 ℃, under such temperature, the liquid in the cell of tissue evaporates rapidly, thereby destruction cell, produce smog, hydrocarbon simultaneously, and this smog is easily carcinogenic, and influences surgical environments; Secondly, exsiccant eschar organization usually sticks on the electric knife head, can cause eschar to come off when taking away electric knife causing hemorrhage again, and this is a difficult problem that often runs in the operation.If the mechanical means with silver brain clip or closer are stopped blooding, tissues such as bulk tissue or trunk such as liver, lung just are difficult to instant healing, adopt closer also to be difficult to eliminate the probability of gallbladder leakage or pneumothorax.

Adopt bipolar coagulation to be about to organize to place between two electrodes have above-mentioned defective equally.

Adopt ultrasonic electric knife, its advantage be insufficiency of blood, operation can be careful, but its operating time is oversize, still wants ligation or titanium to press from both sides, and organizes that to have foreign body on the wound surface residual, and expense is too high really.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of coagulation of tissues electrode catheter.

The technical solution of the utility model is: coagulation of tissues device electrode catheter, comprise a tubule, and its major technique is characterised in that has the hollow pipe road to pass through in the tubule, connect probe on the end, and aperture is set on the probe.

The further technical scheme of this utility model is: its major technique is characterised in that probe diameter is slightly larger than the tubule diameter, the fixedly connected tubule in probe rear end, ball float is set in the probe, the spring that mates with ball float is set behind the ball float, the spring other end is fixed on tubule or the probe.

It is that the normal saline conduction combines that advantage of the present utility model and effect are radio-frequency (RF) energy and liquid, simple in structure, easy to operate; The surgeon uses this utility model can effectively energy delivery be arrived the surface of euangiotic liver parenchyma or other parenchymal visceras, make tissue surface collagen and smooth muscle contraction, produce fast, cleaning, permanent and effective wound healing, control the hemorrhage of substantial viscera, and make to be organized in and just condense before cutting off, reach depletion of blood and cut effects such as liver, prevent the oozing of blood on liver parenchyma surface and hemorrhage again; Simultaneously, since with normal saline as electrode conductor, the normal saline that continuously outflows is lowered the temperature to operation place tissue, usually can reduce to about 100 ℃ from 350 ℃, therefore can prevent to produce eschar and cause again hemorrhage, and can accurately control needs the agglomerative scope of organization, prevents to organize or the perforation of blood vessel, and it is residual not have foreign body on the wound surface; In addition, operating time is short, and patient's misery alleviates.

The specific embodiment

As shown in Figure 1, electrode catheter 1 is that hollow pipeline 2 is set in the tubule, and the one end connects probe 2, and the other end connects normal saline, can directly connect the normal saline bottle, also can add delivery pump; Probe 3 is deep into the tissue place that needs operation, with two utmost points difference conjunctive tissue, the normal saline of radio frequency generator; Then, when needing operation, energized, because crooked probe 3 is facing to tissue, ball float 4 on the probe 3 is (most of in probe 3, fraction then exposes outside probe 3) contact with tissue, then thread goes out normal saline or drop flows out owing to the inside pressuring spring 6 of ball float 4 pressurizeds (a little pressure gets final product), and spring 6 one ends are connected with ball float 4 contacts, and the other end is connected on the probe 3 or on the electrode catheter 1, be fixedly connected in this example on the electrode catheter 1, outflow along with normal saline has formed the loop, and the output radio-frequency (RF) energy is given tissue, produce high temperature, carry out wound healing, pop one's head in simultaneously on 3, the aperture 5 on ball float 4 sides side also drop outflow normal saline is lowered the temperature to wound surface, reduces to about 100 ℃, then wound surface just can not form eschar, and ball float 4 effusive normal saline itself just have certain cooling effect certainly; The flow velocity of normal saline adopts with the matching used drop switch of normal saline bottle and slightly controls, and ball float 4 carries out micro-control.

As shown in Figure 2, electrode catheter 1 is that two hollow pipelines 2 are set in the tubule, same probe 3, ball float 4 are set respectively, or one the tunnel be provided with the probe 3, ball float 4, another road connects electric knife (electrode), two utmost points of radio frequency generator are connected the normal saline that the two hollow pipeline other ends are communicated with respectively, form bipolar coagulation, the same description of operation principle.

This utility model adopts normal saline to conduct electricity, and any liquid that conducts electricity and meet requirements of operation all can use.
