A method for dispensing a bone reinforcement composition into an intervertebral spacer and at least one adjacent vertebra can help retain the implant in situ. A cannula guide is inserted into a first vertebra guided by a live imaging system. A curved directional composition delivery cannula is inserted through a tubular body of the guide; then positioning the delivery cannula along a desired path, positioning an end using a curved end as a steering mechanism. The delivery cannula passes through a first vertebra, into the intervertebral spacer, and optionally into a second vertebra. A volume of reinforcement composition is dispensed using cyclical steps incrementally withdrawing the delivery cannula and dispensing of the reinforcement composition until the desired path is filled with reinforcement composition stabilizing the respective vertebrae and / or interbody devices relative to each other. In an alternate arrangement, the cannula is inserted through a guide integrated into the intervertebral spacer.

The invention discloses a visual trachea cannula guide core device. The visual trachea cannula guide core device comprises a hollow guide core body, a guide wire arranged in the guide core body, a probe installed at one end of the guide wire, a rotary knob assembly arranged on one side of the guide core body and a pressing assembly arranged on one side of the rotary knob assembly. And the knob assembly is provided with a channel through which the guide core body passes and which is connected with the pressing assembly. The probe is electrically connected with an external display device through the guide wire, so that relevant information, detected by the probe, of the width and the height of the laryngeal glottis of a patient can be displayed on the external display device in real time, a doctor can observe the size condition of the laryngeal glottis of the patient in real time, a reference basis is provided for follow-up adapting to tracheal intubation tubes with different diameters, and the patient experience is improved. Meanwhile, the one-time success rate of tracheal intubation can be greatly improved, and the life safety of a patient is guaranteed; the guide wire can be driven to rotate through the knob assembly, so that the angle of the probe can be adjusted to adapt to laryngeal structures of different patients.

The application relates to the technical field of laryngoscopes, and discloses a detachable multifunctional soft tube mirror intubation guide, which comprises a laryngoscope blade and a laryngoscope handle fixedly connected with one end of the laryngoscope blade, and a display screen is electrically connected in the laryngoscope handle; the detachable multifunctional soft tube mirror intubation guide further comprises a support tip movably arranged at one end of the laryngoscope blade away from the laryngoscope handle, the support tip is adjusted in angle through a lifting adjusting assembly to be suitable for different patients, a camera for electrically connecting with the display screen is arranged on an extension end of the laryngoscope blade, and a telescopic lifting assembly is arranged in the laryngoscope blade and extends to one side of the support tip, so that the lifting adjusting assembly can lift the epiglottis to expose the glottis, and smooth ventilation can be realized; the detachable multifunctional soft tube mirror intubation guide solves the problems that the length and angle of the conventional laryngoscope blade are fixed, the adaptability is poor, the laryngoscope blade cannot adapt to physiological differences of throats of different patients, the glottis cannot be accurately exposed, and the quantitative adjusting structure relies on manual experience operation and is prone to cause throat injury of the patient and operation failure.

The invention discloses a fiber bronchoscope oral trachea cannula guiding device, which relates to the related field of clinical anesthesiology, and comprises a fiber bronchoscope body (1), a handle (2) arranged at the right end of the fiber bronchoscope body (1), a fixer (8) for keeping the mouth open and providing an operation space, and an expansion air bag (15) arranged outside the left end of a trachea body (3), and small air bags (17) which are locally expanded and guided are arranged in the expansion air bag (15) at equal angles. In the using process of the fiber bronchoscope oral trachea cannula guiding device, the guiding device can be better attached to the oral cavity through the arrangement of the waist drum-shaped fixing device, the guiding device can be better attached to the mouth of a patient through the arrangement of the sealing bag, pollution caused by saliva flowing out is prevented, meanwhile, the expanding air bag and the small air bag are adopted, and the guiding device is convenient to use. Under the condition that the position of the trachea is fixed, the use angle can be conveniently adjusted, and injury to a patient due to displacement of the tracheal catheter is avoided.

The invention discloses a fiber bronchoscope oral tracheal intubation guiding device, and relates to the field of bronchoscopy, the fiber bronchoscope oral tracheal intubation guiding device comprises a tracheal tube body and a fixing sleeve arranged on the outer side of the bottom end of the tracheal tube body, the right end of the fixing sleeve is fixedly provided with a traction rope, the side face of the tracheal tube body is provided with a hole, and the middle end of the traction rope penetrates through the hole. According to the orotracheal intubation guiding device for the fiberoptic bronchoscope, a fixing sleeve is arranged at the bottom of a trachea body, the side face of the fixing sleeve is connected with a traction rope, the traction rope adopts an eighth surgical incision suture line, and the end portion of the traction rope penetrates into a hole in the side face of the trachea body and penetrates out of the upper end of the trachea body.
