Abstract
The utility model relates to a flectional externally imaging endoscope, which is composed of a camera, a flectional tube, a handle and a casing tube, wherein the periphery of a camera lens is evenly provided with a plurality of light emitting diodes which provide sufficient illumination for a sick part; the lens focuses reflected light signals of the sick part on the surface of a CCD/CMOS image sensor, and after converted to electrical signals, the reflected light signals are transferred to a CCD controller (analog-to-digital conversion) in the handle through a transfer feeder line; after processed by the CCD controller (analog-to-digital conversion), the reflected light signals are transferred to the display terminal of a data processor or a computer in the form of digital signals. Through the rotation of a focusing wheel in the handle, the focal length of the CCD/CMOS image sensor can be precisely adjusted to obtain the clearest picture. Both a doctor and a patient can simultaneously see checking conditions on a display. The flectional tube is formed by the series connection of a plurality of joints which can mutually deflect and can submissively adapt to the bend of cavity paths of a human body. The outside is sheathed with a soft (at least the end part is soft.) transparent disposable casing tube which can ensure imaging definition and can prevent the occurrence of cross infection.
Description
Affiliated technical field
This utility model relates to a kind of medical apparatus and instruments, but the outer imaging endoscope of especially a kind of flexion type of available what scrutineer body cavity tract disease.
Background technology
The body cavities inspection is one of conventional means of diagnosis disease, uses traditional various endoscopies more.Also have the invention of the endoscope aspect that much utilizes optical fiber or recordable use digital image-forming technological means (as " body cavities self-checking unit " ZL03246203.4, " digital optical fiber root pipe microscopy endoscopic lens device " ZL03250696.1) to occur in recent years, can say so respectively has excellent length.But their a common shortcoming is exactly all to be linear, and each tract of human body is always not straight, and this checks to the doctor and makes troubles; Also increased misery to the patient.Especially the patient is carried out the intrauterine inspection, suffer untold misery only not.
Summary of the invention
In order to overcome aforementioned disadvantages, but the utility model discloses the outer imaging endoscope of a kind of flexion type.It can carry out various inspections along body cavities obediently, and the doctor can be directly observes affected part in the tract from computer display screen or data processor display terminal.Regulate lens focus by manual mode and can obtain picture the most clearly.And at any time with digital form recorded and stored photo, in order to postmortem analysis research.
The scheme that its technical problem that solves this utility model adopts is: but the outer imaging endoscope of flexion type is made up of photographic head, flexing pipe, handle, sleeve pipe four parts.Around cam lens, be evenly distributed with some light emitting diodes, for the affected part provides competent lighting condition, affected part image scioptics focus on CCD/CMOS image sensor surface, CCD/CMOS imageing sensor and reflected light signal is converted to the signal of telecommunication inputs to CCD controller (mould/number conversion) in the handle by transmission feeder, after CCD controller (mould/number conversion) is handled, pass to the date processing display terminal or the computer of back by data wire with the form of digital signal; Doctor and patient all can be seen the situation in affected part on the display of data processor display terminal or computer.Can regulate the focal length of CCD/CMOS pick off by handle, thereby obtain distinct image.Photographic head connects with handle by the flexing pipe, and feeder line passes wherein; The flexing pipe is to be formed by a plurality of joints tandem array, and deflection mutually between the joint can adapt to the bending of body cavities obediently.The CCD/CMOS imageing sensor by spring and the tensioning of flexing pipe, spurs the focal length that feeder line can accurately be regulated the CCD/CMOS imageing sensor when taking turns by the focusing in the regulating handle in photographic head; To obtain picture the most clearly.What outer cover is the transparent disposable use sleeve pipe in a softish end, has not only guaranteed the definition of imaging but also can prevent the generation of cross infection.
The beneficial effects of the utility model are: can adapt to the natural torsion of body cavities effectively, reduce patient's misery; Reduced doctor's labor intensity; Realize all observation and inspection processes simultaneously of doctor and patient, just the what both sides carry out effective communication, strengthen mutual trust.Also can write down the reservation check result,, shorten the review time, bring convenience to doctor and patient in order to postmortem analysis research.
Description of drawings
In the accompanying drawing, (1) handle, (2) focusing screw, (3) transmission feeder, (4) sleeve pipe, (5) spring, (6) lens, (7) light emitting diode, (8) CCD/CMOS imageing sensor, (9) photographic head, (10) joint, (11) focusing wheel, (12) spline plate, (13) CCD controller (mould/number conversion), (14) data wire.
The specific embodiment
Below in conjunction with the concrete embodiment of description of drawings.Photographic head (9) connects with the flexing pipe of being made up of some joints (10), and flexing pipe and handle (1) link.The some light emitting diodes (7) that distributing equably around photographic head (9) the end face lens are equipped with lens (6), CCD/CMOS imageing sensor (8), spring (5) in the photographic head (9); Transmission feeder (3) passes the flexing pipe, focusing screw (2) links up the CCD controller (mould/number conversion) (13) in CCD/CMOS imageing sensor (8) and the handle (1).The flexing pipe is connected mutually by several joints (10) and forms, and each joint (10) constitute by two spheres of concave, convex; The centre has passage to pass for transmission feeder.For being had, endoscope leads straight ability, the bigger what concave spherical surface of the radius of curvature of protruding sphere automatically.Have some equally distributed flutings at the concave spherical surface end, both can make things convenient for depanning, make it have certain elasticity again; Assembling clamps by elastic force between two joints (10).Joint (10) but between deflection angle be the poor of protruding sphere cornerite and concave spherical surface cornerite.Spring (5) is located the what confined state between CCD/CMOS imageing sensor (8) and flexing pipe; Transmission feeder (3) is fixed tightly in the focusing screw (2), and the guiding breach of focusing screw (2) is enclosed within on the spline plate, and focusing wheel (11) is used thread connection with focusing screw (2); Rotate the imaging focal length that focusing wheel (11) can be regulated CCD/CMOS imageing sensor (8).Outer cover one (head is at least) transparent, disposable flexible sleeve (4), both can protect photographic head (9), prevents from that cross infection from saving again to use back disinfectant trouble; Can also guarantee the definition of imaging.
Light emitting diode (7) illuminates body cavities, reflected light signal scioptics (6) are at CCD/CMOS imageing sensor (8) surface imaging, and CCD/CMOS imageing sensor (8) converts reflected light signal to the signal of telecommunication through transmission feeder (3) input CCD controller (mould/number conversion) (13); CCD controller (mould/number conversion) (13) converts the electrical signal to digital signal and is transported to (or computer) imaging of data processor display terminal and does the image processing through data wire (14).
