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 tracing device.

Background technique

Medical catheters are commonly used tools in clinical treatment, including two categories: in vitro use and in vivo use. Medical catheters used in the body are usually in contact with tissues, body fluids, blood, etc. during use, so they are usually made of soft medical silicone rubber, latex and other materials.

Because the medical catheter used in the body usually enters the human body from the natural orifice of the human body, such as the urethra and esophagus, the current focus of the medical catheter in the body is usually: 1. The surface performance is convenient, and it should be easy to insert into the body; 2. Biological properties Requirements in terms of safety, non-toxic, will not cause inflammation and foreign body reactions, will not cause allergies, carcinogenic and other adverse effects; 3) Chemical and physical properties are stable, and there will be no performance changes such as hardening.

However, in the clinical operation process, since blood vessels, ureters, fallopian tubes, trachea and other lumens are usually wrapped by tissues, surgeons need long-term training and familiarity with anatomical structures to accurately separate blood vessels, ureters, fallopian tubes, trachea and other lumens. Even experienced surgeons sometimes accidentally injure blood vessels, ureters, fallopian tubes, or trachea. Therefore, a method that can accurately identify blood vessels, ureters, fallopian tubes, or trachea Device for isolumen tubes.

The existing technology is still unable to mark the blood vessels, ureters, fallopian tubes, vas deferens, trachea, etc. hidden in the tissue with visible light, which is not convenient for identification under laparoscopic surgery. Therefore, it is necessary to develop a visible light marking technology and device under a laparoscope, so as to identify lumens such as blood vessels, ureters, fallopian tubes, vas deferens, and trachea under a laparoscope.

The invention discloses a technology and a device for marking blood vessels, ureters, fallopian tubes, vas deferens, trachea and other lumens based on visible light technology.

Contents of the invention

The purpose of the present invention is to solve the problem that blood vessels and various lumens cannot be accurately marked under the endoscope in the existing clinical operation. Blood vessels or lumens that need to be protected during clinical operations can effectively avoid accidental injuries during the operation, so as to facilitate the effective implementation of clinical operations.

The medical catheter with a visible light tracing device of the present invention is characterized in that: the medical catheter with a visible light tracing device 900 includes a catheter 900-1, an interface 900-2 and a medical optical tracing system 500;

A. The catheter 900-1 is made of soft elastic medical material, and has a working channel 900-3 inside;

B. The medical catheter 900 with a visible light tracing device includes at least one 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 set on the catheter 900-1 to identify the location of the catheter 900-1.

The medical optical tracing system 500 can perform optical tracing on the catheter 900-1. During the clinical operation, when approaching the traced lumen, the light emitted by the light source 1 can be seen through the tissue. The light passes through the lumen, and the illuminance of the light emitted by the medical optical tracing system 500 ensures that when the distance from the tube wall is about 0-30mm, the traced lumen is clearly visible, and the closer to the lumen, the stronger the light, prompting The more obvious the effect is, the blood vessel tracing can be effectively carried out during the operation and the medical staff can be prompted to protect important lumens and prevent accidental injuries during the operation. It is very convenient and safe for clinical use.

The medical optical tracer system 500 includes a light source 1 and an optical tracer carrier 2;

A. The optical trace carrier 2 contains a light-guiding material;

B. The light emitted by the light source 1 is transmitted through the optical trace carrier 2, and the optical trace carrier 2 is optically traced.

The light source 1 and the optical tracer carrier 2 can be traced by directly conducting the light emitted by the light source 1 through the light guide material of the optical tracer carrier 2 through direct contact. The light source 1 can also pass the light emitted by the light source 1 through the energy carrier in the optical tracer 2 in a non-contact manner, such as the light-storing self-luminous body 21-1 for storage, and then pass through the energy carrier. Energy conversion emits light for tracing. The light emitting end 11 - 1 of the light source 1 can also be packaged as a whole with the optical trace carrier 2 , and be directly arranged at the position where trace is required.

The light source 1 is an LED light source 11, and/or a medical cold light source 12, and/or natural light. The light source 1 can be various light sources capable of emitting light, and the light emitted by the light source 1 can be traced after being transmitted through the optical trace carrier 1 . Compared with ordinary lighting sources, the LED light source 11 has the characteristics of small size, high luminous efficiency, and strong light source directivity. Especially in terms of safety, LED light sources have incomparable advantages over ordinary light sources. First of all, the LED light source is a low-voltage DC power supply, and the power supply voltage only needs to be 6 to 24V; secondly, no mercury is added to the LED light source, which will not cause poisoning or other harm to the human body; more importantly, the LED light source is a cold light source, which will not cause harm to the human body during work. Severe heat, safe to touch, will not cause unexpected high temperature burns to the human body. The medical cold light source 12 is a commonly used light source in the existing operation process, and the light source 1 can be placed behind, which is easy to obtain in the operating room and does not require additional equipment.

The color of light emitted by the light source 1 can be set according to background color or penetration requirements. Through the setting of the light, in the clinical operation, the doctor can directly see the position of the optical tracer 2 through the tissue with the naked eye, and then accurately identify the blood vessels, tissues or organs that need to be protected during the clinical operation, effectively avoiding Accidental injury during surgery. The light emitted by the light source 1 can be differentiated according to the background color in the body cavity or the tissue to be penetrated. When it is necessary to penetrate the tissue, red and yellow are the best, followed by purple and white. When it is necessary to display vascular tissue , the light is preferably green.

The light source 1 is a flashing type of light emitting. The light source 1 can also be set in the form of intermittent lighting, flashing, etc. as required.

The intensity of light emitted by the light source 1 can be set. The intensity of the light emitted by the light source 1 can also be adjusted as required to adapt to different clinical environments.

The illuminance of the light emitted by the light source 1 can reach 300,000 lux, preferably ranging from 5,000 lux to 150,000 lux.

The light source 1 includes a control system 13, the control system 13 includes a wavelength adjustment mechanism 13-1 and a light intensity adjustment mechanism 13-2, and the wavelength adjustment mechanism 13-1 can adjust the color of the emitted light by adjusting the wavelength , the light intensity adjusting mechanism 13-2 can adjust the illuminance of the emitted light.

The LED light source 11 is arranged inside the body and/or outside the body. Since 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 not only be installed outside the body, and transmit light to the human body through the optical tracer carrier 2, but also can be directly installed In the human body, the optical tracking carrier 2 is coated on the outside and placed directly on the part that needs to be tracked.

The light source 1 and the optical trace carrier 2 are connected in a non-contact or contact manner. The light source 1 can be connected to the optical tracer carrier 2 through the light guide joint 26 to provide a light source, and can also illuminate the optical tracer carrier 2 without contact, such as the light-storing self-luminous tracer carrier 21 The tracking of the optical tracking carrier 2 is realized through the storage and conversion of light energy.

The LED light source 11 is contact-connected to the optical trace carrier 2 , and the LED light source 11 is arranged in the optical trace carrier 2 . The optical trace carrier 2 is directly wrapped on the outside of the LED light source 11, and the LED light source 11 and the optical trace carrier 2 are put into the human body together to trace the lumen.

The optical tracer 2 is a light-storage self-luminous tracer 21 . Self-luminous materials refer to materials that can absorb energy in a certain way and convert it into non-equilibrium light radiation. The process of converting the energy absorbed inside the material into non-equilibrium light radiation is the luminescence process. In particular, light-storing self-luminescent materials can continue to emit light for more than 12 hours in a dark environment after a few minutes or tens of minutes under the action of external light, which can meet the tracing needs of most operations. The light-storing self-illuminating tracer carrier 21 can directly absorb the energy of the light in the operating room, so that various external lights can form the light source 1, and there is no need to directly connect the light source 1, and the use process is very simple.

The light-storage self-luminous tracer carrier 21 includes a light-storage self-illuminator 21-1 and a protection carrier 21-2.

The protective carrier 21-2 is made of a transparent light-guiding material, and the light-storing self-luminous body 21-1 is closed and arranged in the protective carrier 21-2.

The light-storing self-luminous body 21-1 can absorb external energy and convert it into light. The protective carrier 21-2 is made of transparent medical materials, which can be directly in contact with tissues. The light energy converted from the light-storing self-illuminating body 21-1 effectively passes through for effective tracing, and at the same time ensures clinical Biosafety used. The light-storing self-illuminating body 21-1 can be arranged in different positions and designed in different shapes, and can perform fixed-point tracking or overall tracking as required.

The light guiding fiber 22 has a smooth surface. When the light guiding fiber 22 has a smooth surface, due to the good light guiding performance of the light guiding fiber 22, the light outlet 22-2 of the light guiding fiber 22 is located at the far end of the light guiding fiber 22, which can Realize fixed-point tracing.

The light-guiding optical fiber 22 is intermittently provided with a light outlet 22-2. Each of the light outlets 22-2 provided intermittently has a light transmission surface 22-21 and a reflection surface 22-22, the light is transmitted through the transmission surface 22-21, and when it reaches the reflection surface 22-22, The light is reflected and emitted from the light outlet 22-2 to form a tracer point, and a plurality of the light outlets 22-2 can form a chain tracer strip.

The light outlet 22 - 2 is a non-axial light outlet 22 - 21 , which is arranged on the side of the light guide fiber 22 along the length direction of the light guide fiber 22 . When the light outlet 22-2 is completely set along the length direction of the light guide fiber 22, the light guide fiber 22 can be lighted as a whole along the length direction of the light guide fiber 22 to realize the light guide fiber 22 overall tracer.

Through the regular arrangement of the light outlets 22 - 2 , the light outlets 22 - 2 can mark the length dimension of the light guiding optical fiber 22 .

The regular arrangement of the distribution density of the light outlets 22 - 2 leads to different intensities of scattered light, and the length dimension of the light guiding optical fiber 22 is marked.

When the light outlets 22-2 are closely arranged, the emitted light is stronger and the visual effect is brighter; when the light outlets 22-2 are arranged scattered, the emitted light is weaker and the visual effect is darker. A combination of light and shade can form a visual effect similar to a ruler, and at the same time of tracing, it can also achieve the effect of size marking.

The light-guiding optical fiber 22 is braided into a net shape, and light outlets 22-2 are scattered in different positions. The light-guiding optical fiber 22 is braided into a net shape, and the length of each of the light-guiding optical fibers 22 can be set to be different, and the light outlets 22-2 of the light-guiding optical fiber 22 are also different thereupon, scattered and distributed, which can be To realize the overall tracking in the three-dimensional space, since the light outlet 22-1 does not need to be arranged in the middle of each light-guiding optical fiber 22, the light transmission effect is better, and the visual effect of a single tracking point is very bright. It is also possible to weave the light-guiding optical fiber 22 that is provided with the light outlet 22-2 on the side and can be lighted as a whole into a net shape, so as to realize full-area tracing of the entire cavity. Moreover, the shape of mesh weaving can have good support, which is especially suitable for the support and tracking of large cavities, such as bladder and uterus.
