Description
Technical field
The invention belongs to medical diagnosis stereoscopic imaging technology field, especially relates to a kind of stereo endoscope with quick-locking device.
Background technology
Stereo endoscope, as intervention means new in medical diagnosis applications, in use to inside of human body three-dimensional imaging, can provide sufferer information more accurately for doctor, avoid the maloperation of surgical.Existing stereo endoscope substantially all comprises diagnosis lens body and divides and image processing section.Diagnosis lens body divides general action in inside of human body, therefore generally can be stained with the materials such as body fluid after finishing using, and stereo endoscope is before all adopt single use, causes medical treatment cost higher.Afterwards in order to reduce medical treatment cost, be just adopted as the method for front end perspective endoscope cleaning sterilization.But the image processing section of rear end generally all adopts the electronic units such as imageing sensor, can not high-temperature sterilization be carried out, just stereo endoscope be put into particular device thus, front and rear part be isolated, then front end diagnosis lens body is divided and carry out disinfection.Although stereo endoscope can be reused like this, this special sterilizing equipment decontaminating apparatus is expensive, does not play the effect reducing medical treatment cost.That this front and back isolating seal is general, therefore not thorough to the sterilization of front end on the other hand.
The split type stereo endoscope occurred in prior art can solve the problem can not sterilized separately front end, but the syndeton of stereo endoscope front and rear part arranges fairly simple, mostly adopts the connection locking structure of thread-locking type.Because stereo endoscope inside has dual light path, quality and volume are all large than conventional endoscope, and the cross section of double light path is Long Circle, and single thread locking structure can not thoroughly be locked.Simultaneously along with use helicitic texture there will be loosening, cause the separation of stereo endoscope front and back end to cause and come off.
Summary of the invention
The problem that the invention will solve is, provides a kind of stereo endoscope with quick-locking device, solves the stereo endoscope front and back end existed in prior art and connects locking instability, easily cause problems such as loosening and come off.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is:
A kind of stereo endoscope with quick-locking device is provided, comprise endoscope's part, lock portion and camera part, described lock portion comprises sight glass cover, and the front end of described sight glass cover and the rear end of endoscope's part are connected and fixed, and described sight glass cover rear end embeds in a locking loose collar;
The top of locking loose collar is embedded with a spring block, and spring block is connected with a spring, and the other end of spring is connected with spring catch nail barrel; Spring catch nail barrel width is less than the width of spring block, and the lower end of spring catch nail barrel embeds in the spring pin groove of sight glass cover;
Described locking loose collar also comprises a guiding breach, adaptive with the navigation button of camera part.
Further, described sight glass cover also comprises a shop bolt groove, and described locking loose collar also comprises a locating notch, and described shop bolt groove and locating notch are all adaptive with shop bolt, and described shop bolt lower end is threaded with locknut.
Further, described camera part adopts imageing sensor, and described imageing sensor is the one in ccd sensor, 3CMOS sensor or DPS sensor.
The advantage that the invention has and good effect are: can quick-detachment or locking endoscope part and camera part, solve in prior art and loosen because locking insecure and stereo endoscope front and back end that is that occur the problem being separated and coming off.

Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
Embodiment 1:
In embodiment 1, the structure of the invention comprises endoscope's part, lock portion and camera part.Lock portion comprises sight glass cover, and the front end of sight glass cover and the rear end of endoscope's part are connected and fixed, and described sight glass cover rear end embeds in a locking loose collar.The top of locking loose collar is embedded with a spring block, and spring block is connected with a spring, and the other end of spring is connected with spring catch nail barrel; Spring catch nail barrel width is less than the width of spring block, and the lower end of spring catch nail barrel embeds in the spring pin groove of sight glass cover.Described locking loose collar also comprises a guiding breach, adaptive with the navigation button of camera part.
In use, camera part alignd with lock portion and insert, noting navigation button to contact with the guiding breach of lock portion, now pressing locking loose collar, due to the effect of spring, spring catch nail barrel moves relative to spring block.Width due to spring catch nail barrel is less than the width of spring block, and the top that therefore spring catch nail barrel is blocked a shot in the inside that spring is blocked a shot and spring is moved in opposite directions, locks the overall sight glass cover relatively of loose collar thus and moves down.Then navigation button is embedded in guiding breach, stop pressing locking loose collar afterwards, release due to spring force makes the relative sight glass cover of locking loose collar move up, and navigation button is fixed in guiding breach, now just completes the connection locking of endoscope's part and camera part.If need dismounting, pin locking loose collar, navigation button and guiding breach are separated.
Embodiment 2:
In example 2, sight glass cover also comprises a shop bolt groove, and described locking loose collar also comprises a locating notch, and described shop bolt groove and locating notch are all adaptive with shop bolt, and described shop bolt lower end is threaded with locknut.
In use, camera part alignd with lock portion and inserts, noting navigation button to contact with the guiding breach of lock portion, now shop bolt being inserted the locating notch of locking loose collar and the shop bolt groove of sight glass cover.Pressing shop bolt, now pressure passes to spring catch nail barrel by sight glass cover and then passes to the spring be connected with spring catch nail barrel, the overall sight glass cover relatively of locking loose collar is moved down, navigation button is embedded in guiding breach, stop pressing shop bolt afterwards, release due to spring force makes the relative sight glass cover of locking loose collar move up, and navigation button is fixed in guiding breach, now just completes the connection locking of endoscope's part and camera part.Then be threaded with shop bolt fixing with locknut, now complete endoscope's part and the locking of camera part and fastening.If need dismounting, take off locknut, pressing shop bolt, navigation button and guiding breach are separated.
Embodiment 1 all can be set to hook solid with the guiding breach in embodiment 2, is convenient to like this connect and stationary positioned button, makes locking more firm.Sight glass is sheathed counts Long Circle or rectangle, to adapt to the bifocal path structure of stereo endoscope.
Embodiment 1 is a base case of the invention, can complete endoscope's part and the basic locking of camera part fast, can not cause because to rock or service time is long and endoscope's part that is that cause came off with separating of camera part.Embodiment 2 adds shop bolt and locknut on the basis of embodiment 1, can be fastening further on the basis of locking, now locking loose collar can not overlap with sight glass because of pressing and produce relative movement, that avoids the maloperation locking loose collar of doctor in performing the operation to cause endoscope's part and camera part to be locked loosens, and increases the safety coefficient of locking.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
