Description
Technical field
The invention belongs to medical instruments fields, and in particular to the dedicated handle of medical laser optical fiber a kind of and handle hole away from
From detection and warning device.
Technical background
Laser is a kind of clinically common medical instrument, be chiefly used in Minimally Invasive Surgery field carry out pathological tissues cutting,
The surgical procedures such as blood coagulation, rubble.Its primary operational method is into the sheath for penetrate human body while to be inserted into endoscope and one straight
About 200~800 μm of optical fiber of diameter, it is in need for the treatment of that laser (energy) through endoscopic observation, by optical fiber is imported into human body by doctor
Implement operation in position.Currently, being widely used in needle holder being applied to surgery Minimally field.
But it is had the following defects in process of clinical application：
Requirement when 1, by laser machining process, the length that optical fiber end brings out operating walk way out into the open are about maintained at a 3-10 millimeters of left sides
The right side, and at a distance from optical fiber endpoint requires to keep different between different target tissues, it can be only achieved preferable vaporization cutting tissue
Or the effect of explosion crushed stone；It needs operator to move plug operating parts and optical fiber in clinical operation, be aligned with luminous point
Target simultaneously controls certain distance and can be only achieved good therapeutic effect.Since fibre external diameters are 200-800 microns, only with finger
Very thin optical fiber is operated, is easy to shake, lacks stable and accuracy；In addition a plurality of pipeline is carried on operator assembly, operation
Person is hanging moving operation again, it is difficult to accomplish to accurately control on schedule in place, often will appear the deviation of luminous point and target range, remote
It is ineffective, it is close or can accidentally injure tissue more than target, bring many difficulties to being smoothed out for operation；
2, optical fiber end bring out into the open out operating walk way length lack control, be inserted into optical fiber when, due to insertion unstability with
Possible unexpected generation, exists and is inserted into too deep and too shallow possibility, when being inserted into too deep, optical fiber may be to biological tissue of human body
Generate harm；If insertion is too shallow, i.e., optic fibre end returns in the sheath of channel, and laser can be to endoscope lens or other instruments
Thermal damage is caused, and endoscope is expensive, to increase doctors and patients' burden.
Invention content
It is an object of the invention to be directed to deficiency in the prior art, a kind of medical laser optical fiber for capableing of ranging is provided.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of medical laser optical fiber for capableing of ranging, including optical fiber ontology, sheath and connector, the sheath are fixed with connector
Connection, further includes optical fiber handle, range unit and circuit board for measuring distance between optical fiber handle and connector, the circuit
Plate is equipped with power-supply controller of electric, microprocessor and display unit, and the power-supply controller of electric is powered for circuit board and range unit,
The microprocessor is for storing, calculating and output data, while the working condition of also control display unit.
The range unit is electromagnetic induction range unit or optical distance measurement apparatus.
The electromagnetic induction range unit is made of the first electromagnetic induction coil and the second electromagnetic induction coil, and described first
Electromagnetic induction coil is located on connector and is electrically connected with power-supply controller of electric, and second electromagnetic induction coil is located at optical fiber handle
On.
Further include protective shell, first electromagnetic induction coil and circuit board are located in protective shell, the protective shell with connect
Head is fixedly connected.
The optical fiber handle is made of two movable sleeves and fastening silica gel ring, and described two movable sleeves are connected through a screw thread,
The fastening silica gel ring is located between two movable sleeves.
Further include host, the microprocessor outputs data to host by wired or wireless network.
Optical fiber handle primarily serves the effect of two aspects, and the first effect is easy for doctor and operates very thin optical fiber, to
The stability of operation is improved, the second effect is to provide a reference to measure the length variation of optical fiber ontology port section of stretching out
Point can accurately show that the length of optical fiber ontology port section of stretching out becomes by measuring the variation of the distance between optical fiber handle and connector
Change.Optical fiber handle in the present invention also has the advantages that installation, convenient disassembly, while can also play protection to optical fiber ontology and make
With.
Protective shell mainly plays protection circuit plates, prevents outside liquid from flowing into damage circuit board.It can also prevent simultaneously
Alternating electromagnetism field intensity around first electromagnetic induction coil is excessively high to interfere indoor other medical instruments of performing the operation.
The present invention can be by the length change information immediate feedback of the optical fiber ontology port section of stretching out measured to doctor, convenient for doctor
The raw depth for grasping fiber port when performing the operation at any time prevents port to be inserted into the too damage of pursuit of advanced studies adult body tissue or port and moves back
It returns in sheath and thermal damage is caused to endoscope lens, to improve the accuracy of operation and reduce the cost of operation, have
It is born conducive to doctors and patients are reduced.
Description of the drawings
Fig. 1 is the cross-sectional view of medical laser fiber in embodiment 1.
Fig. 2 is the circuit block diagram of the present invention.
Specific implementation mode
