Description
Technical field
The utility model relates to arthroscopes, more particularly to a kind of disposable arthroscope system.
Background technique
Arthroscope is a kind of optical instrument for observing intra articular structure, is the endoscope for diagnosis and treatment joint diseases.It is logical
Complete observation can be carried out to intra-articular structure by crossing arthroscope, so as to directly observe many intra-articular structures and lesion
And treatment, and the traumatic wounds generated are subtleer compared with cutting operation.As endoscopic technique is gradually popularized in China, especially
The fast development of minimally invasive medical technology, present arthroscopic techniques have become the diagnostic method and treatment technology of standard, constitute
The important component of joint surgery.
Requirement with patient to minimally invasive medical technology increasingly improves, and to arthroscope, higher requirements are also raised.For example,
In order to reduce infection probability, reduce doctor or patient's waiting disinfecting time, toxic side effect during reduction disinfection personnel decontamination,
It is required that using disposable articulated mirror.In addition, in the course of surgery, in order to make doctor preferably observe the structure in articular cavity,
Ask observation visual angle that can change.However, what existing arthroscope observation visual angle was usually fixed, it is unfavorable for doctor and observes articular cavity
Interior structure.For example, US9370295B2 discloses a kind of disposable visualization device, for treating in articular cavity
Tissue damage.Only about 10 degree of the observation visual angle of the equipment insertion section front lens, it is unfavorable for doctor and easily observes in articular cavity
Portion's structure and lesion.Although CN206381162 U solves sight by using the steering combined prism for making optical axis turn predetermined angle
The lesser problem in visual angle is examined, but structure is complicated and is only capable of that optical axis is made to turn 30 degree for joint lens head.
CN206381162 U also solves existing miniature webcam in mirror body front end, electronic equipment can't stand sterilizing or
The problem of sterilizing poor resistance, but still need to sterilize, and the time of sterilization process waste doctor and patient, to disinfection personnel
Toxic side effect, while being unfavorable for hospital and saving disinfection cost, it in addition still remains observation visual angle and fixes, be unfavorable for doctor's observation
The problem of articular cavity internal structure and lesion.
In the prior art, arthroscope is not able to rotate when in use, is unfavorable for doctor and is observed articular cavity internal structure.
Such as disclosed in the CN206381162 U in the lens device of joint, arthroscope mirror body is locked in disposable lens barrel by locking device,
Keep arthroscope fixed.In this case, doctor can not more easily be observed in articular cavity by cradle head mirror
Structure and lesion.
It can be seen that above-mentioned existing arthroscope is in structure and use, it is clear that there are still inconvenient and defects, and urgently
It is further improved.To solve the above problems, the present inventor is based on professional knowledge and practical experience abundant,
Positive research and innovation can improve general existing arthroscope, have more it to found a kind of new structural arthroscope
There is practicability.By constantly studying, designing, and by repetition test sample and after improving, creates and have practical value finally
The utility model.
