Description
Technical field
The invention belongs to field of medical appliances, be specifically related to have the cystoscope system of the band infrared heat scanheads of infrared heat scan function.
Prior art
Medical infrared imaging derives from military industrial technology, use the history in existing more than 40 year, along with medical science, infrared imaging, and the development of multiple technologies such as multimedia, the temperature resolution of infrared imaging has reached 0.05 degree, spatial resolving power has reached 0.8mrad, image definition is greatly improved, the interpretation of result intuitive and convenient, and its range of application clinically enlarges.Infrared imaging diagnosis at present demonstrates certain advantage in the following areas: 1, judge position, scope, the degree of acute and chronic inflammation; 2, the blood supply functional status of monitoring vascular lesions; 3, tumor early warning indication, the omnidistance supervision and the curative effect assessment.This shows, during infrared imaging to the important supplement of other morphology diagnostic methods such as B ultrasonic, CT, MR.
Cystoscope is the core apparatus that carries out the urology department operation, cystoscope is connected with shooting main frame, monitor and cold light source main frame, cooperates various operating theater instruments, and the doctor can be through per urethram feeding in the bladder cavity, handle the bladder pathological changes, comprise calculus, polyp and tumor etc.
Do not occur still at present that both are incorporated into the endoscopic system of exercising usefulness in conjunction with cystoscope with the infrared heat scanheads.Therefore, a kind of cystoscope system technology with infra-red heat scan function that the infrared heat scanning technique is used in combination with cystoscope of design is extremely urgent.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of cystoscope system with infra-red heat scan function is provided, this cystoscope system is introduced infrared heat scanheads and system in the cystoscope system, by the infrared heat scanheads wall of urinary bladder tissue is carried out successive stereoscan, transfer of data to the infrared heat scanning system main frame that the continuous crosscut scanning in many planes obtains carries out Flame Image Process, the three-dimensional blood vessel still image of clear demonstration wall of urinary bladder, make the doctor according to the display image that obtains, by analyzing the infra-red heat scanogram of bladder, understand the function of bladder, obtain beyond thought diagnosis effect.
In order to realize above-mentioned technical purpose, the present invention is achieved through the following technical solutions:
Cystoscope system with infrared heat scan function of the present invention, comprise hard cystoscope and the cold light source main frame that is connected with the hard cystoscope, shooting main frame, scope monitor, also be provided with the infrared heat scanning system on the described hard cystoscope, described infrared heat scanning system comprises infrared heat scanheads, infrared heat scan process system host and infrared heat scanning system monitor.
In the present invention, described hard cystoscope comprises cystoscope main part, the sheath tube portion that is connected with the cystoscope main part, states the sheath tube portion and comprises sheath tube end, intake tunnel and exhalant canal.
Described hard cystoscope main part can be divided into following two kinds of forms according to its used optical system difference:
First kind of form is to adopt the cystoscope of electronics ccd optical system, and this form cystoscope main part structure specifically comprises hard scope end, data input pin, cold light source input, and at least one linear type instrument channel;
Second kind is the cystoscope that adopts prism optical system, and this form cystoscope main part structure specifically is to comprise hard scope end, data input pin or eyepiece input, cold light source input, and at least one linear type instrument channel.
As the further improvement of above-mentioned technology, the diameter of the linear type instrument channel on the described cystoscope main part is more than or equal to 3.0mm.
In the present invention, described infrared heat scanheads comprises probe work end, operator handle and data wire, described probe work end is passed the linear type instrument channel of cystoscope main part and is stretched out from the front end of hard scope end, described data wire is connected with infrared heat scan process system host by joint, and described infrared system monitor is connected with infrared heat scan process system host.
The front end of described probe work end is the first end of probe, and described probe working end minister 500～2000mm, described probe tip minister degree are less than 50mm, and the first end of described probe external diameter is smaller or equal to 3.0mm.Described probe is provided with ultrared in the first end, and one group of infrared facility is installed in the ultrared at least, and described infrared facility comprises infrared light supply emitter and infrared reception camera lens.Specifically, the infrared facility of described ultrared is three groups, and these three groups of infrared facilitys are mutually 60 degree designs.Ultrared can be rotated by the driving of motor, and does linear and annular moving, thereby does linear and annular scanning to being scanned body; Its operator bar structure comprises gauge tap, mode selection switch, inching switch etc.
