Description

Medical catheter with visible light tracer
Technical Field
The invention relates to a medical catheter, in particular to a medical catheter with a visible light tracer device.
Background
Medical catheters are a common tool in clinical treatment, and include two main types, in vitro use and in vivo use. Medical catheters used in vivo are usually in contact with tissues, body fluids, blood, etc. during use, and are therefore usually manufactured from soft medical silicone rubber, latex, etc.
Because medical catheters used in vivo generally enter the human body from natural passages of the human body, such as urethra and esophagus, the current medical catheters in vivo are usually focused on: 1. the surface performance is convenient, and the insertion into the body is convenient; 2. the requirements on biological performance are safe and nontoxic, and the requirements on inflammation and foreign body reaction and adverse effects such as allergy, cancerogenesis and the like are avoided; 3) The chemical and physical properties are stable, and the hardening and other property changes can not occur.
However, in the clinical operation process, since the lumen such as the blood vessel, the ureter, the oviduct, the trachea and the like is generally wrapped by tissues, a surgeon needs to be trained for a long time and is familiar with an anatomical structure, so that the lumen such as the blood vessel, the ureter, the oviduct, the trachea and the like can be accurately separated. Even a surgeon with a great experience may accidentally injure a vessel, a ureter, a fallopian tube, a trachea or other lumen, and therefore, a device capable of accurately identifying a vessel, a ureter, a fallopian tube, a trachea or other lumen in a tissue is required.
The prior art can not perform visible light identification on blood vessels, ureters, fallopian tubes, vas deferens, trachea and the like hidden in tissues, and is inconvenient for the identification of the operation under the endoscope. Therefore, there is a need to develop a technique and apparatus for endoscopic visual identification to facilitate endoscopic identification of vessels, ureters, fallopian tubes, vas deferens, trachea and other lumens.
The invention discloses a visible light technology-based identification technology and a visible light technology-based identification device for lumen tubes such as blood vessels, ureters, fallopian tubes, vas deferens and trachea.
Disclosure of Invention
The invention aims to solve the problem that blood vessels and various lumen tubes in the existing clinical operation cannot be accurately marked under a endoscope, and by adopting the arrangement of an optical tracing mode, the blood vessels or lumen tubes which need to be mainly protected in the clinical operation are accurately distinguished by the arrangement of light sources with different colors in the clinical operation, so that accidental injury in the operation process is effectively avoided, and the effective implementation of the clinical operation is facilitated.
The invention relates to a medical catheter with a visible light tracer device, which is characterized in that: the medical catheter 900 with the visible light tracer device comprises a catheter 900-1, an interface 900-2 and a medical optical tracer system 500;
A. The catheter 900-1 is made of soft elastic medical materials, and is internally provided with a working channel 900-3;
B. the medical catheter 900 with the visible light tracer device at least comprises 1 interface 900-2, and the interface 900-2 is arranged at the proximal end 900-12 of the catheter 900-1;
C. the medical optical tracking system 500 is disposed on the catheter 900-1 and identifies the location of the catheter 900-1.
The medical optical tracing system 500 can optically trace the catheter 900-1, and in the clinical operation process, when approaching the lumen to be traced, the light emitted by the light source 1 can be seen through tissues to permeate the lumen, the illuminance of the light emitted by the medical optical tracing system 500 is ensured to be clearly visible when being about 0-30mm away from the wall of the tube, and the closer to the lumen, the stronger the light is, the more obvious the prompting effect is, the vascular tracing can be effectively performed in the operation and the medical staff is prompted, the important lumen is protected, the accidental injury in the operation is prevented, and the clinical use is very convenient and safe.
The medical optical tracing system 500 comprises a light source 1 and an optical tracing carrier 2;
A. the optical tracing carrier 2 contains a light guide material;
B. the light emitted by the light source 1 is conducted through the optical tracing carrier 2 and optically traces the optical tracing carrier 2.
The light source 1 and the optical tracing carrier 2 can directly conduct the light emitted by the light source 1 through the light guide material of the optical tracing carrier 2 for tracing in a direct contact mode. The light source 1 may also store the light emitted by the light source 1 through the energy carrier in the optical tracing carrier 2, such as the light-storage self-luminous body 21-1, and then trace the light emitted by the energy conversion. The light emitting end 11-1 of the light source 1 can be packaged with the optical tracing carrier 2 into a whole, and the whole can be directly arranged at a position where tracing is required.
The light source 1 is an LED light source 11, and/or a cold medical light source 12, and/or natural light. The light source 1 may be various light sources capable of emitting light, and the light emitted by the light source 1 may be tracked after being conducted by the optical tracking carrier 1. Compared with a common illumination light source, the LED light source 11 has the characteristics of small volume, high luminous efficiency, strong light source directivity and the like, and particularly has the advantage in the aspect of safety, which is incomparable with the common light source. Firstly, the LED light source is powered by low-voltage direct current, and the power supply voltage is only 6 to 24V; secondly, mercury is not added into the LED light source, so that the harm such as poisoning and the like to a human body can be avoided; in addition, more importantly, the LED light source is a cold light source, can not seriously generate heat in the working process, can be touched safely, and can not cause unexpected high-temperature scalding to a human body. The cold medical light source 12 is a common light source in the existing operation process, and the light source 1 can be arranged at the rear, so that the cold medical light source is easy to obtain in an operating room and does not need extra equipment.
The color of the light emitted by the light source 1 can be set according to the background color or the penetration requirement. Through the arrangement of the light rays, in the clinical operation, a doctor can directly see the position of the optical tracer carrier 2 through the tissues by naked eyes, so that the blood vessels, tissues or organs which need to be protected in a key way in the clinical operation can be accurately distinguished, and the accidental injury in the operation process can be effectively avoided. The light emitted by the light source 1 can be differently set according to the background color in the body cavity or the tissue to be penetrated, when the tissue to be penetrated is required, the red color and the yellow color are better, the purple color and the white color are inferior, and when the vascular tissue to be displayed is required, the light is better.
The light source 1 emits light in a blinking manner. The light source 1 may also be configured to intermittently light, flash, etc. as desired.
The intensity of the light emitted by the light source 1 may be set. The intensity of the light emitted by the light source 1 can also be adjusted according to the needs so as to adapt to different clinical environments.
The illuminance of the light emitted by the light source 1 can reach 30 kaleilux, and the preferable range is 5 kilolux to 15 kaleilux.
The light source 1 comprises a control system 13, the control system 13 comprises a wavelength adjusting mechanism 13-1 and a light intensity adjusting mechanism 13-2, the wavelength adjusting mechanism 13-1 can adjust the color of emitted light through wavelength adjustment, and the light intensity adjusting mechanism 13-2 can adjust the illumination of the emitted light.
The LED light source 11 is arranged in the body and/or in the body. Because the volume of the light emitting end 11-1 of the LED light source 11 can be very small, the LED light source 11 can be not only arranged outside the body to conduct light to the human body through the optical tracing carrier 2, but also can be directly arranged in the human body, and the optical tracing carrier 2 is coated outside the body to be directly arranged at the part needing tracing.
The light source 1 and the optical trace carrier 2 are connected in a contactless or contact-type manner. The light source 1 may be connected to the optical tracing carrier 2 through the light guide connector 26 to provide a light source, or may be used for non-contact irradiation of the optical tracing carrier 2, such as the light-accumulating self-luminous tracing carrier 21, to implement tracing of the optical tracing carrier 2 through storage and conversion of light energy.
The LED light source 11 is connected with the optical tracing carrier 2 in a contact mode, and the LED light source 11 is arranged in the optical tracing carrier 2.

The optical tracer carrier 2 is a light-accumulating self-luminous tracer carrier 21. Self-luminescent materials refer to materials that are capable of absorbing energy in some way, converting it into unbalanced light radiation, the process of converting the energy absorbed inside the material into unbalanced light radiation being the luminescence process. Especially, the light-storage self-luminous material can continuously emit light for more than 12 hours in a dark environment after a few minutes or a few ten minutes under the action of external illumination, so that the tracing requirement of most operation time can be met. The light-accumulating self-luminous tracing carrier 21 can directly absorb the energy of lamplight in an operating room, so that various external illuminations can form the light source 1, the light source 1 is not required to be directly connected, and the use process is very simple.
The light-accumulating self-luminous tracing carrier 21 comprises a light-accumulating self-luminous body 21-1 and a protective carrier 21-2.
The protection carrier 21-2 is made of transparent light guide material, and the light-accumulating self-luminous body 21-1 is arranged in the protection carrier 21-2 in a sealing way.

The light outlet 22-2 is a non-axial light outlet 22-21, and is disposed on a side surface of the light guide fiber 22 along a length direction of the light guide fiber 22. When the light outlet 22-2 is integrally arranged along the length direction of the light guide fiber 22, the light guide fiber 22 can be integrally lightened along the length direction of the light guide fiber 22, so that the integral tracing of the light guide fiber 22 is realized.
By the regular arrangement of the light outlets 22-2, the light outlets 22-2 can identify the length of the light guide fiber 22.
The length of the light guide fiber 22 is marked by the regular arrangement of the distribution density of the light outlets 22-2, which causes the scattered light to have different intensities.
When the light outlets 22-2 are arranged tightly, the emitted light is stronger and the visual effect is brighter, when the light outlets 22-2 are arranged and dispersed, the emitted light is weaker and the visual effect is darker, and the visual effect similar to a scale can be formed through the arrangement mode of light and shade combination, so that the effect of size identification can be achieved while tracing.
The light guide fiber 22 is woven into a net shape, and light outlets 22-2 are scattered at different positions. The light guide fibers 22 are woven into a net shape, and the lengths of the light guide fibers 22 can be set to be different, so that the light outlets 22-2 of the light guide fibers 22 are also different, and are scattered and distributed, and the integral tracing of the three-dimensional space can be realized. The light outlet 22-2 may be arranged on the side surface, and the light guide fiber 22 capable of being lighted integrally may be woven into a net shape, so as to realize the full-area tracing of the whole cavity.

Detailed Description
Example 1: single-cavity medical catheter with visible light tracer device
Referring to fig. 1 to 1-14, in this embodiment, the medical catheter 900 with a visible light tracing device is a medical gastric tube 901.
Referring to fig. 1 to 1-4, the medical catheter 900 with a visible light tracing device is a medical gastric tube 901, and comprises a catheter 900-1, a connector 900-2 and a medical optical tracing system 500.
The catheter 900-1 is made of a soft elastic medical material, a working channel 900-3 is arranged in the catheter, and a working opening 900-11-1 is arranged at the distal end 900-11.
Referring to fig. 1 and 1-1, the medical gastric tube 901 includes 1 of the connectors 900-2, the connectors 900-2 being disposed at the proximal end 900-12 of the catheter 900-1.
The medical optical tracking system 500 is disposed on the catheter 900-1 and identifies the location of the catheter 900-1.
The medical optical tracing system 500 comprises a light source 1 and an optical tracing carrier 2.
Referring to fig. 1-3 and 1-4, the light source 1 may be an LED light source 11, and/or a cold medical light source 12, and/or natural light. The light source 1 may be various light sources capable of emitting light, and the light emitted by the light source 1 may be tracked after being conducted by the optical tracking carrier 1. Compared with a common illumination light source, the LED light source 11 has the characteristics of small volume, high luminous efficiency, strong light source directivity and the like, and particularly has the advantage in the aspect of safety, which is incomparable with the common light source. Firstly, the LED light source is powered by low-voltage direct current, and the power supply voltage is only 6 to 24V; secondly, mercury is not added into the LED light source, so that the harm such as poisoning and the like to a human body can be avoided; in addition, more importantly, the LED light source is a cold light source, can not seriously generate heat in the working process, can be touched safely, and can not cause unexpected high-temperature scalding to a human body. The cold medical light source 12 is a common light source in the existing operation process, and the light source 1 can be arranged at the rear, so that the cold medical light source is easy to obtain in an operating room and does not need extra equipment.
The color of the light emitted by the light source 1 can be set according to the background color or the penetration requirement. Through the arrangement of the light rays, in the clinical operation, a doctor can directly see the position of the optical tracer carrier 2 through the tissues by naked eyes, so that the blood vessels, tissues or organs which need to be protected in a key way in the clinical operation can be accurately distinguished, and the accidental injury in the operation process can be effectively avoided. The light emitted by the light source 1 can be differently set according to the background color in the body cavity or the tissue to be penetrated, when the tissue to be penetrated is required, the red color and the yellow color are better, the purple color and the white color are inferior, and when the vascular tissue to be displayed is required, the light is better.
The light source 1 can be set to be intermittently lightened, twinkled and the like according to the needs, and the intensity of the light rays emitted by the light source 1 can be adjusted according to the needs so as to adapt to different clinical environments. The illuminance of the light emitted by the light source 1 can reach 30 kaleilux, and the preferable range is 5 kilolux to 15 kaleilux.
Referring to fig. 1-4, the light source 1 includes a control system 13, the control system 13 includes a wavelength adjusting mechanism 13-1 and a light intensity adjusting mechanism 13-2, the wavelength adjusting mechanism 13-1 can adjust the color of the emitted light by adjusting the wavelength, and the light intensity adjusting mechanism 13-2 can adjust the illuminance of the emitted light.
Referring to fig. 1-8 to 1-12, the LED light source 11 may be provided in the body or may be provided in the body. Because the volume of the light emitting end 11-1 of the LED light source 11 can be very small, the LED light source 11 can be not only arranged outside the body to conduct light to the human body through the optical tracing carrier 2, but also can be directly arranged in the human body, and the optical tracing carrier 2 is coated outside the body to be directly arranged at the part needing tracing.
In this embodiment, the light source 1 and the optical trace carrier 2 are connected in contact.
When the light source 1 is arranged outside the body, the optical trace carrier 2 is a light guiding optical fiber 22. The light guide fiber 22 has good light guide effect, can transmit light to different positions according to the needs, can be switched on or off according to the needs, and is very convenient for clinical use.
The light source 1 is connected to the light guide fiber 22 through the light guide connector 26 to provide a light source.
Referring to fig. 1-1, the optical tracing carrier 2 includes 1 of the light guide optical fibers 22, and the light guide optical fibers 22 are disposed along the length direction of the light guide 900-1.
Referring to fig. 1-1 and 1-2, when the light guide fiber 22 has a smooth surface, the light outlet 22-2 of the light guide fiber 22 is located at the distal end of the light guide fiber 22, so as to perform a fixed point tracing on the distal end 90-11 of the catheter 900-1 due to the good light guiding performance of the light guide fiber 22.
The light guide fiber 22 may also be circumferentially arranged along the side wall of the catheter 900-1, and an aperture may be formed at the distal end of the catheter 900-1 to locally trace the distal end of the catheter 900-1.
Referring to fig. 1-5 through 1-7, when the light guide fiber 22 has a non-smooth surface 22-1, the non-smooth surface 22-1 is a non-smooth surface 22-11 that is capable of forming reflection, and/or scattering. The non-smooth surface 22-1 can realize the whole luminescence of the non-smooth surface 22-1 through the reflection and/or scattering of light rays, so as to achieve the whole tracing effect.
The light guide fiber 22 is provided with a light outlet 22-2 in a discontinuous manner. Each light outlet 22-2 is provided with a light conducting surface 22-21 and a reflecting surface 22-22, the light is conducted through the conducting surface 22-21, when reaching the reflecting surface 22-22, the light is reflected and emitted from the light outlet 22-2 to form a tracing point, and a plurality of the light outlets 22-2 can form a chain tracing band.
Referring to fig. 1-7, the light outlet 22-2 is a non-axial light outlet 22-21, and is disposed on a side surface of the light guide fiber 22 along a length direction of the light guide fiber 22. When the light outlet 22-2 is integrally arranged along the length direction of the light guide fiber 22, the light guide fiber 22 can be integrally lightened along the length direction of the light guide fiber 22, so that the integral tracing of the light guide fiber 22 is realized.
The length of the light guide fiber 22 is marked by the regular arrangement of the distribution density of the light outlets 22-2, which causes the scattered light to have different intensities.
When the light outlets 22-2 are arranged tightly, the emitted light is stronger and the visual effect is brighter, when the light outlets 22-2 are arranged and dispersed, the emitted light is weaker and the visual effect is darker, and the visual effect similar to a scale can be formed through the arrangement mode of light and shade combination, so that the effect of size identification can be achieved while tracing.
In addition, the light guide fiber 22 may be woven into a mesh, and the light outlets 22-2 are scattered at different positions, see fig. 4 to 5-1. The light guide fibers 22 are woven into a net shape, and the lengths of the light guide fibers 22 can be set to be different, so that the light outlets 22-2 of the light guide fibers 22 are also different, and are scattered and distributed, and the integral tracing of the three-dimensional space can be realized. The light outlet 22-2 may be arranged on the side surface, and the light guide fiber 22 capable of being lighted integrally may be woven into a net shape, so as to realize the full-area tracing of the whole cavity. The shape of the mesh weave can have good support, and is particularly suitable for supporting and tracing large cavities such as bladders, uterus and the like.

The developing mechanism 4 is a developing line 41 (refer to fig. 1-6), and/or a developing ring 42 (refer to fig. 1-9), and/or a developing block 43 (refer to fig. 1-2). The applicant has only exemplified the above development modes, and in practical application, a person skilled in the art can design different development modes according to the needs, and the applicant does not exemplify the development modes herein, but does not depart from the protection scope of the present application.
The developing mechanism 4 performs development under X-ray, and/or MRI, and/or B-ultrasonic. The developing mechanism 4 can carry out developing prompt under the scenes of X-ray, magnetic navigation, B ultrasonic and the like, and the developing mechanism 4 is convenient for the optical tracing carrier 2 to be placed under the condition of visual or navigation.
The optical tracing carrier 2 is made of flexible medical materials and can move along the cavities of blood vessels, ureters, esophagus, trachea, fallopian tubes, vas deferens and the like. The optical tracing carrier 2 has good flexibility and can move along a blood vessel or a cavity, so that the optical tracing carrier 2 can be placed at different positions according to the needs.
Referring to fig. 6, the optical pick-up carrier 2 may further comprise a shaping mechanism 25. The shaping mechanism 25 may shape the optical tracing carrier 2, such as round, arc, sphere, etc., according to the need, so as to adapt to different tracing needs.
The shaping mechanism 25 is a shape memory shaping mechanism 25-1. The shape memory shaping mechanism 25-1 has a simple structure such as a linear shape, a strip shape and the like at room temperature, so that the shape memory shaping mechanism can be conveniently placed into a human body and then can be restored to a set shape under the action of body temperature.
The shape memory shaping mechanism 25-1 is made of shape memory wire braiding, and/or shape memory metal tubes or sheets are engraved. The shape memory shaping mechanism 25-1 may be a shape memory wire woven into a desired shape, or may be a shape memory alloy tube or a shape memory alloy sheet directly engraved into a desired shape.
When the LED light source 11 is designed in a micro manner, the size of the light emitting end 11-1 is generally controlled below 2mm, for example, the LED lamp with the packaging size of 0.2 mm-0.5 mm, and the light emitting end of the LED light source 11 can be arranged in the wall of the catheter 900-1 and directly enter the body. At this time, the catheter 900-1 constitutes the optical trace carrier 2.

In addition, the light emitting end 11-1 of the LED light source 11 and the flexible circuit board may be disposed on the outer surface of the catheter 900-1 along the length direction of the catheter 900-1, and the optical trace carrier 2 may be coated outside.
The light source 1 and the optical tracing carrier 2 can also irradiate the optical tracing carrier 2 in a non-contact way, for example, the light-accumulating self-luminous tracing carrier 21 can realize tracing of the optical tracing carrier 2 through storage and conversion of light energy.
The optical tracer carrier 2 is a light-accumulating self-luminous tracer carrier 21. Self-luminescent materials refer to materials that are capable of absorbing energy in some way, converting it into unbalanced light radiation, the process of converting the energy absorbed inside the material into unbalanced light radiation being the luminescence process. Especially, the light-storage self-luminous material can continuously emit light for more than 12 hours in a dark environment after a few minutes or a few ten minutes under the action of external illumination, so that the tracing requirement of most operation time can be met. The light-accumulating self-luminous tracing carrier 21 can directly absorb the energy of lamplight in an operating room, so that various external illuminations can form the light source 1, the light source 1 is not required to be directly connected, and the use process is very simple.
Referring to fig. 1-14 and 1-15, the light-accumulating self-luminous tracing carrier 21 contains a light-accumulating self-luminous body 21-1 and a protective carrier 21-2.
The protection carrier 21-2 is made of transparent light guide material, and the light-accumulating self-luminous body 21-1 is arranged in the protection carrier 21-2 in a sealing way.
The light-accumulating self-luminous body 21-1 can absorb external energy and perform conversion luminescence. The protective carrier 21-2 is made of transparent medical materials, can be directly contacted with tissues, and can effectively track the light energy emitted by the light storage self-luminous body 21-1 through effective energy conversion and simultaneously ensure the biological safety of clinical use. The light-accumulating self-luminous body 21-1 can be arranged at different positions and designed into different shapes, and fixed-point tracing or integral tracing is carried out according to the requirement.
