Abstract

The utility model discloses a minitype tubular electric coagulation forceps/electric coagulator for subpial transaction and cortex fulguration, which comprises an insulation forceps handle and an electric conduction part and a switch which are arranged in the insulation forceps handle. An insulation layer is respectively coated on the inner surface and the outer surface of a metallic elongated hollow tubular outer pipe, and the tail end of the outer pipe is bent and is connected with an electric coagulation head; the insulation layer is respectively coated on the inner surface and the outer surface of the outer pipe; the outer pipe is electrically connected with a left plug through the electric conduction part, wherein the left plug is arranged at the end of the insulation forceps handle; the insulation layer is coated on the surface of a metallic elongated silky inner rod; the inner rod is matched with the inner wall of the outer pipe; the tail end of the inner rod is also bent and is electrically connected with the electric coagulation head of the tail end of the outer pipe; the inner rod is electrically connected with a cable through the switch, wherein the cable is arranged in the insulation forceps handle; and the cable is electrically connected with a right plug arranged at the end of the insulation forceps handle. Due to the fact that the appearance of the electric coagulation forceps/electric coagulator is in an elongated tube shape and has small volume and small occupied space, the surgery field is wider; the minitype tubular electric coagulation forceps/electric coagulator can go deep into a narrow deep cavity to stop tissues bleeding and can effectively prevent the tissues from being burnt. The utility model has simple structure and convenient operation and use.

Description

Be used for mini-type tubular electric coagulation forceps/device that crosscut and cortex are fulgerized under the mantle

Technical field

This utility model relates to medical apparatus and instruments, is specifically related to a kind of mini-type tubular electric coagulation forceps/device that crosscut and cortex are fulgerized under the mantle that is used for.

Background technology

Bipolar coagulation forceps is one of anthemorrhagic operation apparatus of various surgical operation indispensabilities, especially in neurosurgery process, use the most frequent and the most key, the tradition electric coagulation forceps is made of tweezer body, tweezer handle etc., as patent 200620167853.5 and patent 200620021062.1, its operation principle is: when two tweezers point is closed, two tweezer points, hemostasis position form the loop, the electric current hemostasis position of flowing through, thus reach the hemostasis purpose.But, when this bipolar coagulation forceps is fulgerized operation at the cortex that is used for the epilepsy surgery, there are several major defects: 1. tweezer body and elastic flat pointed electrode, volume is bigger, taken limited operative space, having tunnel vision, stops blooding in the petechia that is difficult to reach the narrow dark chamber of inside of human body bottom section; 2. conduct heat to the brain deep from the top layer of cortex, should not control the scope of fulgerizing, cause excessive damage easily; 3. electricity coagulates the incrustation of appearance easily in the process, organizes adhesion, charred tissue, tractive to cause problems such as hemorrhage again.In addition, crosscut is the most frequently used art formula of epilepsy surgery under the mantle, but, traditional method is to adopt brain book to carry out machinery from disconnected at nervous tissue, as easy as rolling off a log generation subarachnoid hemorrhage, bring many complication, become denouncing of this effective art formula, how to bring into play the advantage of above-mentioned two kinds of art formulas, overcome the major defect of two kinds of art formula used tools simultaneously, we have invented and a kind ofly can take into account crosscut function under the mantle simultaneously, can accomplish that again crosscut limit, limit electricity coagulates, hemostasis, effectively control fulgerize scope and heat transfer direction, incrustation do not occur, tissue adheres to, the bipolar coagulation forceps of charred tissue---be used for mini-type tubular electric coagulation forceps/device that crosscut and cortex are fulgerized under the mantle.This operating theater instruments (tubulose bipolar coagulation forceps) to ensure operation smoothly, improve operative effect, reduce postoperative complication and have important function.

Summary of the invention

This utility model is at the drawback that the traditional operation apparatus tweezer that uses in the operation exists of fulgerizing of crosscut and cortex under the epilepsy surgery mantle, provide a kind of and can take into account crosscut function under the mantle simultaneously, can accomplish that again crosscut limit, limit electricity coagulates, hemostasis, the bipolar coagulation forceps of adhesion, charred tissue does not appear forming a scab, organizing in effective fulgerize scope and heat transfer direction of control---be used for mini-type tubular electric coagulation forceps/device that crosscut and cortex are fulgerized under the mantle.

Described in the utility modelly be used for mini-type tubular electric coagulation forceps/device that crosscut and cortex are fulgerized under the mantle, comprise insulation tweezer handle, be located at electric-conductor in the insulation tweezer handle, laterally pass the switch of insulation tweezer handle, it is characterized in that:

The surfaces externally and internally of the outer tube of one metal elongate hollow tubulose all is coated with insulating layer coating, and its end is bending and is connected with electriocoagulator; The surfaces externally and internally of outer tube all is coated with insulating layer coating, and outer tube is electrically connected with the left plug that is located at insulation tweezer pommel portion by electric-conductor;

The surface-coated insulating barrier of the interior bar of one metal fine filaments cooperates with the inwall of outer tube, and the end of interior bar also is bending and is electrically connected with the electriocoagulator of outer tube end; Interior bar is electrically connected with cable in being located at insulation tweezer handle by switch, and this cable is electrically connected with the right plug that is located at the tweezer pommel portion of insulating.

Describedly be used for mini-type tubular electric coagulation forceps/device that crosscut and cortex are fulgerized under the mantle, the external diameter of its described outer tube is between 1-3mm, and the outer tube bendable is converted into one or more snippets various curved shapes.

Describedly be used for mini-type tubular electric coagulation forceps/device that crosscut and cortex are fulgerized under the mantle, its described switch is decided to be and is connected on the insulation tweezer handle, can adopt pressing type or plug-type closure and the disconnection of carrying out current loop.

During use, the outer tube end is touched on the point or face that needs blood coagulation, Closing Switch, during the logical formation of outer tube and interior rod guidance closed-loop path, bipolar current is switched on, and electric current forms the loop by the outer tube end, thereby realizes the hemostasis point that touches is carried out electric coagulation hemostasis.

This operating theater instruments (tubulose bipolar coagulation forceps) to ensure operation smoothly, improve operative effect, reduce postoperative complication and have important function.In addition, it also has and takes up room for a short time, and open surgical field of view can reach the petechia in narrow dark chamber, and can effectively prevent advantages such as electric coagulation forceps adheres to, charred tissue, and is simple in structure, easy to use.Be specially adapted to neurosurgery epilepsy surgery Minimally Invasive Surgery.

This utility model is compared with prior art and had the following advantages: because profile is an elongated tubular product such, volume is little, occupies little space, so the surgical field of view broad can be deep in the narrow dark tract the tissue hemostasis; The contact area of electriocoagulator and tissue is big, can prevent charred tissue effectively; Also have tractive simultaneously, collude or push aside the function of tissue; Simple in structure, easy for operation, exterior appearance.
