Abstract: Disclosed are an apparatus and a method for predicting a passage time and a driving time of vehicles in a waiting line section, which pass through the waiting line section disposed behind an intersection. The apparatus inputs information on speeds of the vehicles to a trained prediction model and more accurately predicts the time for users to arrive at his or her destinations.

Abstract: Disclosed is a method of unilateral biportal endoscopy and a surgical instrument set used in the same. More particularly, the present invention relates to a method of unilateral biportal endoscopy which separately secures a working portal for surgical instruments and an endoscopic portal for an endoscope, thereby providing a more accurate spinal surgery, and to a surgical instrument set which can be effectively applied to the method.

Abstract: The present invention relates to a high-frequency treatment device for spinal endoscopic surgery, the device including: a casing; an insert rod extending in a longitudinal direction of the casing; and an electrode tip formed at a front end of the insert rod to apply heat to a treatment part. Accordingly, it is possible to not only immediately remove in-body soft tissues or ligaments that interfere with the visual field of an endoscope in an operation, but quickly stop bleeding, and it is also possible to discharge contaminated substances with a saline solution from a treatment part, thereby allowing an accurate and effective operation.

Abstract: A direction adjustable surgical tissue removal device, including: an insert rod having a stopping step at a front end; a slider slidably coupled to the insert rod, moving forward and backward with respect to the stopping step, and having a punching portion forming a jaw in cooperation with the stopping step; a rotary shaft being a hollow member fixed behind the insert rod and rotated by a user; a pushing rod having a front end fixed to the slider sequentially through the rotary shaft and the insert rod and a rear end extending backward; a spring disposed between the rotary shaft and the rear end of the pushing rod and elastically supporting the pushing rod backward; and a handle accommodating a portion of the rotary shaft and moving the pushing rod forward such that the punching portion is pushed toward the stopping step.

Abstract: The present invention relates generally to a method of unilateral biportal endoscopy and diamond shaver used in the same. The method includes: securing pathways for a working portal and an endoscopic portal that extend toward a surgical site in the body of a patient and are distanced from each other; inserting a surgical instrument required for surgery into the secured working portal; inserting an endoscope into the endoscopic portal; performing surgery using the surgical instrument inserted into the working portal while monitoring the surgical site through the endoscope; removing the surgical instrument and the endoscope after the performing the surgery; and suturing of suturing entrances of the working portal and the endoscopic portal.
