Description
Technical field
Burn the present invention relates to a kind of water cooling microwave and cut heat setting knife, be suitable for surgery open surgery to the dissection of organ-tissue with
Cutting is used, and medical microwave technical applications are belonged to.
Background technique
" microwave thermal " in 20th century makes microwave heat therapeutic almost spread to domestic hospital, each institute.With modern science and technology
It rapidly develops, microwave technology is treated in microwave reason (heat) and the clinical field of microwave superficial tissues is formed as arteries and veins application point at first
Branch.
In Clinical Surgery's open surgery, microwave coagulation treatment is frequently as the surgical instrument for dissecting or cutting organ-tissue.It institute
To be with applications well prospect: from macroscopically see microwave coagulation treatment cutting tissue, and it is microcosmic on see that it is just same with high rate
When implement thermocoagulation hemostasis.Microwave coagulation treatment is considered one kind and is designed to surgical instrument shape in the process for completing cutting tissue
The microwave antenna of shape with the electromagnetic energy of several hundred million secondary alternations (hyperfrequency) per second in affected tissues, and make tissue separation by burn cut,
The result left after heat setting hemostasis simultaneously.So microwave cutting operation is typically considered safe and efficient and other are low
Frequently active instrument is incomparable.
In microwave coagulation treatment cutting operation, since host is by output high-power microwave energy, the microwave in microwave knife bar is passed
Defeated coaxial line will give out very high heat, this inevitably generates heat the operation handle for making instrument hot.For this purpose, existing micro-
The knife bar of wave knife is very thick, and handle is very big, compared with the high frequency knife of import, at least wants heaviness to four to five times.However, due to microwave
Cutter has fool proof and efficient advantage, is allowed to still be applied in Clinical Surgery's open surgery so far.
Summary of the invention
The present invention is directed to the defect and deficiency of existing microwave coagulation treatment, proposes that a kind of water cooling microwave burns and cuts heat setting knife, puts forth effort simultaneously
Structure in microwave antenna field source position designs, and enables the invention to more safely and efficiently be applied to Clinical Surgery to organ group
The cutting or dissection operation knitted.
A kind of water cooling microwave of the present invention, which burns, cuts heat setting knife, comprising: point of a knife radiation head, knife bar, medium tube, semi-rigid coaxial electrical
The inner conductor of cable, the semi-rigid coaxial cable is connected with point of a knife radiation head, it is characterised in that: described further includes that a front end has knife
The outer tube of sword, for the outer tube sleeve in medium tube and semi-rigid coaxial cable, the knife bar front end sleeve is loaded on the tail of the outer tube
Portion, interior be equipped with of the knife bar covers the inner water sleeve pipe outside semi-rigid coaxial cable, between the inner water sleeve pipe and semi-rigid coaxial cable
Gap form inlet channel, gap between the inner water sleeve pipe and knife bar forms return water road.
Further characteristic of the invention is as follows:
1, the point of a knife radiation head is stainless steel material, and front end is thin cone, and surface coats Teflon, so that point of a knife spoke
Penetrating head has the characteristics that adhesion under high self-lubrication and high temperature.
2, the outer tube is stainless steel material, and surface coats Teflon, so that outer tube has under high self-lubrication and high temperature
The characteristics of adhesion.
3, outer tube is knife-edge tubular body, and is had there are two blade, two of point of a knife radiation head front end and the outer tube
The line of blade exterior point and operation face are in for 45 ° and 30 ° of angles respectively.
4, the inner conductor of the semi-rigid coaxial cable is fitted into point of a knife radiation head-tail blind hole and is fixed, the medium
Pipe encapsulation is on the cylindrical body of point of a knife radiation head-tail.
5, the outer tube has front end inner hole and back-end central hole, and the front end inner hole encapsulation of the outer tube is in medium tube tail portion
Shoulder outer circle on, back-end central hole encapsulation is on the semi-rigid coaxial cable.
6, further include having handle, the water jacket being connected with inlet channel is provided in the handle, what is be connected with return water road returns
Water jacket, the water inlet tap being connect with water jacket, and the return water mouth with return water set connection.By the semi-rigid coaxial cable, inner water sleeve
The unimodal current circulatory system that pipe, knife bar and water jacket, return water set are formed with radio frequency connector.I.e. cooling water is injected by water inlet tap
In water jacket, then through clearance flow between semi-rigid coaxial cable and inner water sleeve pipe to knife bar front end, then through inner water sleeve pipe and knife bar it
Gap flow back into return water set, then is flowed out by return water mouth, moves in circles to form the water cooling system of unobstructed one-way circulation with this.
7, the handle has handle set, handle tube, light pipe seat, switch base and the handle cap being connected to one, institute
It is fixed between handle tube and handle cap after stating light pipe seat and switch base fastening, handle set is fixed on the rear portion of handle tube, described
It is provided on switch base for controlling the bright microswitch for cutting the work of heat setting knife of the water cooling microwave, is equipped on the light pipe seat
It is used to indicate the light emitting diode of working condition.
8, handle is further fixed on connection four core shielded wire of host general control system, two in the four cores shielded wire with
Microswitch is connected, and in addition two are connected with light emitting diode.
In conclusion prominent features of the invention are: (1) the point of a knife radiation head of thin cone and front end are the outer of knife-edge
Pipe is respectively the coaxial inner conductor and coaxial outer conductor for transmitting microwave, and thereby inspires electromagnetic wave, two components it is special
Shape and its composition not only extremely suit the cutting application of surgical operation, but also are relatively beneficial to the bright of microwave and cut and to the heat of notch
Solidifying hemostasis.(2) line and operation face of point of a knife radiation head front end and blade exterior point are separately designed as 45 ° and 30 ° of two kinds of oblique angles,
Be conducive to clinical operation to apply and selection optimum operation.(3) knife bar and water-cooling circulating system composed by part in handle, can have
The structural members such as the cooling outer tube in effect ground, semi-rigid coaxial cable, knife bar and radio frequency connector, and carry away a large amount of heat to cutter hub it
Outside.To be allowed to stable working performance, operation application is more safe and efficient.(4) handle is equipped with microswitch and is able to cooperate hand
Starting/stopping of art real-time control microwave improves the sensitivity manipulated to host.Dichromatic LED on handle, can be clear
The working condition of microwave output is shown clearly.
In short, a kind of water cooling microwave of the present invention burns and cuts heat setting knife, not only microwave operational characteristic good, has especially with water-cooling structure
The stability and the safety of operation of instrument are improved to effect, the manipulation of switches and double color luminotron on handle are shown further
Increase the intelligence of its surgical procedure, knife bar outer diameter of the invention small (thin) can arrive and any a active cutting operation utensil phase
It matches in excellence or beauty.
