Description

Visual support

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a visual support for transferring an organ needing to be protected in an operation.

Background

In medical related surgical procedures, particularly in the process of cutting off a part of tissue, a doctor usually makes a position judgment through empirical judgment. The procedure is affected by the surgical field, and the bile duct is easily damaged by mishandling if careless during the resection procedure. In addition, patients with difficult bile duct searching can be quickly found and treated by the stent due to heavy adhesion of multiple operations. The first is to avoid the organ being damaged, the second is to quickly find and handle difficult exposures.

In order to solve the problem, the patent publication CN212816661U discloses an intraoperative visual biliary stent implantation device, which determines the specific position of a metal wire in a body by coating fluorescent powder on the surface of the metal wire and observing the fluorescent powder. In the patent publication CN210904582U, a multi-lumen medical balloon dilatation catheter is disclosed, in which an dilatation channel, a guiding channel and an instrument channel are disposed in an inner tube, which are isolated from each other, so that the optical fiber can be used to extend into the affected part for visualization operation during the operation.

None of these techniques directly solves the problem of the current display positioning in gallbladder surgery, etc., but can be improved according to its working principle.

SUMMERY OF THE UTILITY MODEL

The utility model aims to realize the purpose of changing the traditional wire harness light source into the spherical light source for displaying and positioning in the operation process by improving the visual support, and provides accurate reference for the operation.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a visual support, includes interconnect's pipe and sacculus, the pipe includes interior pipe and outer pipe, is provided with the sidelight optic fibre between interior pipe and the outer pipe, the sacculus includes interior sacculus and outer sacculus, interior sacculus and the sealed intercommunication of interior pipe, outer sacculus and the sealed intercommunication of outer pipe are provided with a plurality of luminous silks including between sacculus and the outer sacculus, and luminous silk and sidelight optic fibre are connected.

In the above technical scheme, the inner surface of the outer balloon is provided with a light diffusion layer.

In the technical scheme, the outer surface of the inner balloon is provided with a reflective layer.

In the technical scheme, the inner surface of the outer balloon is provided with a light scattering layer, and the outer surface of the inner balloon is provided with a light reflecting layer.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

the utility model has simple structure, simple principle and convenient operation, can realize the brightness adjustment of the sidelight optical fiber according to the power of the input light source, ensures that the luminous source expands into a spherical shape along with the expansion of the balloon, changes the luminous radius, changes the traditional light source into a spherical light source, increases the light source area, increases the illumination range, realizes the display in the bile duct and avoids the misoperation of the operation.

Drawings

The utility model will now be described, by way of example, with reference to the accompanying drawings, in which:

FIG. 1 is a schematic structural diagram of an embodiment;

FIG. 2 is a schematic cross-sectional view of a catheter;

wherein: 1 is an inner tube, 2 is an outer tube, 3 is a side-light optical fiber, 4 is a first balloon, 5 is a second balloon, 6 is a light emitting filament, 7 is a light scattering layer, and 8 is a light emitting layer.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in fig. 1 and 2, the structure of the present embodiment includes two parts, a catheter part and a balloon part. The catheter part is divided into two layers of catheters, wherein the inner tube 1 is a hollow tube and is mainly used for passing through fluid media; the inner tube 1 and the outer tube 2 are coaxially arranged, a plurality of side light optical fibers 3 are arranged between the inner tube 1 and the outer tube 2, and filling media are filled in gaps among the inner tube 1, the outer tube 2 and the side light optical fibers 3.

The balloon part comprises a double-layer balloon, wherein the first balloon 4 is an outer layer, the second balloon 5 is an inner layer, and the first balloon 4 is coated on the outer surface of the second balloon 5. In the balloon setup, the second balloon 5 is in communication with the inner tube 1, and a fluid medium is passed through the inner tube 1 into the interior of the second balloon 5 for filling the second balloon 5 and inflating the second balloon 5. The first balloon 4 is inflated along with the inflation of the second balloon 5.

When the first balloon 4 and the second balloon 5 are in a non-expansion state, a gap is formed between the first balloon 4 and the second balloon 5, a plurality of luminous wires 6 are arranged in the gap, and the luminous wires 6 are communicated with the side optical fibers 3. Meanwhile, a light diffusion layer 7 is arranged on the inner wall of the first balloon 4 and used for diffusing the light source emitted by the luminous wire 6, and a light emitting layer 8 is arranged on the outer wall of the second balloon 5 and used for emitting the light source emitted by the luminous wire 6, so that the light source is diffused towards the outside of the balloon.

In this embodiment, in order to achieve better effect, the first balloon 4 is made of a transparent medium, so that it has good light transmittance.

In this embodiment, all the light sources are in the sealed space, and the light sources do not directly contact with human tissues, so as to avoid harm to human body.

In the embodiment, the light source is a cold light source, so that the damage of the conventional strong light source to human tissues is avoided.

In the embodiment, the intensity of the light source is adjustable, so that the problem that the blood cannot be distinguished in the operation process is avoided, and a very good visual display effect is achieved.

In this embodiment, the light emitting source is expanded into a spherical shape by the inflation of the balloon, the light emitting radius is changed, the traditional light source is changed into a spherical light source, the light source area is increased, and the illumination range is increased.

The utility model is not limited to the foregoing embodiments. The utility model extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
