Description
Technical Field
The invention relates to the technical field related to medical equipment, in particular to functional three-dimensional reconstruction of images of urethral stricture and viscoelasticity.
Background
Urethral viscoelasticity is a property that maintains the normal physiological function of the urethra. When a human body needs to urinate, urine acts on the surface of urethral mucosa, so that the urethra is promoted to be opened, and the urine can flow out conveniently. That is, the urethra viscoelasticity response is an important index of the urethra dilatation. Normal human urethral viscoelasticity is highly compliant and has low urethral resistance, but no examination can produce a continuous, intuitive objective value or result.
The calculation of urethra viscoelasticity is related to urine flow rate, urine itself, pressure of urine on the duct, diameter of urethra, degree of urethra expansion, and the like. Through the measured values, mathematical formula conversion is carried out, and finally a urethra viscoelasticity result can be obtained.
In the case of a clinically encountered urethral stricture, we need to perform a urethroscopy. Only urethral stricture was observed, but the length of the stricture, the diameter of the stricture, the flow rate of urine passing therethrough, and objective evaluation of urethral viscoelasticity could not be accurately observed. We need to perform a urethrography examination to assess the location of the stenosis, the length of the stenosis, etc. The operation is carried out by two steps, synchronization and visual objective standards are not provided, the operation is troublesome, and the experience of patients in clinic is not good.
How to design a device for monitoring the change of the pressure in the urethra, the change of the flow velocity, the diameter of the urethra, the degree of the urethral stricture (the diameter of the urethral stricture), the length of the urethral stricture, the degree of the urethral dilatation (the diameter of the urethral dilatation) and the like at the same time while performing urethroscopic observation of the stricture and video recording. And then can carry out the objective data evaluation of urethra stenosis and urethra viscoelasticity, can also carry out three-dimensional image reconstruction and become the most important thing of present research, and there is system standard to urethra whole journey under 3 dimension continuous visual mode.

Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the technical scheme in the embodiment of the invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the invention.
Referring to fig. 1, the present embodiment is realized by the following technical solution, which comprises a platform 1 and a cystoscope 2; the bottom of the platform 1 is provided with a cavity 3, a rolling shaft 4 is arranged in the cavity 3, a hose 5 is wound on the rolling shaft 4, two ends of the rolling shaft 4 are respectively in rotating connection and matching with the inner wall of the cavity 3, two ends of the hose 5 are respectively in sealed butt joint with an inflow port of the cystoscope 2 and an output end of a physiological saline tank 6, a camera module 7 in the cystoscope 2 is in data butt joint with a computer terminal through Bluetooth, and the platform 1 is in data butt joint with the computer terminal through Bluetooth.
The following will further explain the application method and the principle of the technical solution part in this embodiment with reference to the accompanying drawings:
first, a cystoscope 2, which is generally used in clinical practice, is provided with an inflow port and an outflow port, and a tube 5 is connected to the inflow port and can flow out from the lens end of the cystoscope 2 at a constant flow rate. The other end of the hose 5 is connected to the normal saline, the middle of the hose 5 passes through the cavity 3, and the hose 5 is folded by using the rolling shaft 4, so that the control of the flow speed, the pressure, the flow and the time of the normal saline flowing through the hose 5 is realized. And early warning of the upper limit values of pressure and flow rate.
When a narrow section of the urethra or a section of the urethra with poor viscoelasticity is encountered, the time required for the preset amount of liquid to pass through the narrow section or the section with poor viscoelasticity at a constant flow rate is observed. Compared with the time taken for the urethra to have no stenosis or the urethra to have viscoelasticity under normal conditions, the preset liquid amount is used at a constant flow rate. Before these operations can begin, the hose 5 needs to be filled with water and then the bladder needs to be emptied.
After data and images are collected, the data and the images are transmitted to a computer through Bluetooth, and finally calculation and three-dimensional reconstruction of the images are carried out through software of the computer.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
