Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to a method and equipment for endotracheal intubation. Background Art

[0002] In comprehensive ICU wards, comatose patients are often admitted. If it is determined that the patient needs intubation for more than 21 days, the intubation should be changed to tracheotomy. Studies have shown that tracheotomy 7 days before admission can bring significant benefits to patients with traumatic brain injury (TBI). The hospitalization time and hospitalization costs of patients with traumatic brain injury (TBI) in the delayed tracheotomy (LT) group (>10 days) were significantly higher than those in the early tracheotomy (ET) group (<10 days). Compared with traditional tracheotomy, percutaneous tracheotomy does not require surgical intervention. The Seldinger dilation technique is used to directly incise the skin to implant a tracheotomy cannula. This is called percutaneous tracheotomy, which is one of the common clinical operations of ICU doctors.

[0003] Tracheotomy is a commonly used method for establishing an artificial airway in clinical practice. It refers to a method in which an incision is made in the anterior wall of the trachea and a tube is inserted to allow air to enter the trachea and lungs directly without passing through the nasal cavity, pharynx and larynx. It is often used to relieve upper airway obstruction, prevent aspiration of the airway and clear endotracheal secretions, connect a ventilator for mechanical ventilation, reduce ventilation dead space, treat obstructive sleep apnea, etc. In addition, major oral, maxillofacial and neck surgeries and neck trauma will also be performed preventively. Tracheotomy has the advantages of being easily tolerated by patients, reducing breathing work, reducing anatomical dead space, reducing sedation, facilitating suction and oral care, and reducing the risk of upper respiratory tract infection.

[0004] At present, most of the tracheotomy devices on the market use bronchoscopes to observe and then cut the designated area. However, this method generally requires a lot of preparation time and operation time, which results in a lot of time spent on tracheotomy. In addition, the wire of the bronchoscope will frequently rub against the patient's throat area when moving. At the same time, percutaneous tracheotomy has the risk of bleeding, tracheal and esophageal damage, and tracheoesophageal fistula, which makes the patient feel uncomfortable after the operation. As a result, the existing tracheotomy devices cannot be used in combination and cannot reduce the friction between the wire and the patient. Therefore, a device is needed to improve the above-mentioned problems. Summary of the invention

However, the device adopts an endoscopic design, which can greatly reduce the damage to the posterior wall of the trachea and the esophagus and avoid the occurrence of tracheoesophageal fistula.

[0029] A method for operating an endotracheotomy device comprises the following steps: S1. First, connect the control handle 3 to the external display system, then open the upper and lower jaws of the patient, and place the support frame 26 between the upper and lower jaws, so that the support frame 26 can support the upper and lower jaws. Then, the wire harness 35 can be passed through the absorption nozzle 12 and the plastic ring 22, so that the wire harness end 34 can enter the patient's trachea. Through the setting of the lighting lamp 31, the suction pipeline 30 can be guided to absorb the sputum inside the patient's trachea, which is convenient for medical staff to observe the inside of the trachea; S2. Afterwards, the medical staff can mark the area on the patient's body surface where the intubation is required, and then rotate the harness end 34 until the monopolar electrosurgical unit 32 faces upward, and turn on the red spot irradiation lamp 33, so that the red spot light beam can be displayed on the patient's body surface, which is convenient for the medical staff to quickly move the monopolar electrosurgical unit 32 to align with the marked area; S3. Finally, operate the control handle 3 to start the electric knife head extending out of the monopolar electric knife component 32, aim at the red marking point, use electric cutting to slowly cut the mucosa from the tracheal mucosal surface in a transverse incision, and use electric coagulation to stop bleeding while cutting. Cut subcutaneously, cut the skin, check for bleeding, push the wire harness end 34 out of the trachea, insert the tracheotomy tube from the incision, remove the endotracheal tube, and fix the opening tube.

[0030] The working principle of embodiment 1 is as follows: when in use, firstly connect the end of the control handle 3 away from the wire harness 35 to the external display screen, then raise the patient's head and shoulders, perform local anesthesia, then open the patient's upper and lower jaws, put them into the support frame 26, and fit the upper and lower jaws to the upper and lower ends of the support frame 26 to avoid the patient's upper and lower jaws from merging. Subsequently, the wire harness 35 can be passed through the absorption nozzle 12, the plastic ring 22 and the guide sleeve 25 in sequence until the wire harness end 34 enters the patient's trachea. At this time, the setting of the guide sleeve 25 can avoid the wire harness 35 from contacting the patient's throat, reducing the friction on the patient's inner cavity. The setting of the lighting lamp 31 can illuminate the inside of the patient's trachea. At the same time, the control handle 3 can be operated to pass through the suction pipe 30 to The sticky sputum on the inner wall of the trachea is absorbed and discharged, completing the cleaning of the inner wall of the trachea. Subsequently, the medical staff can mark the position where the intubation is required on the patient's body surface, and then operate the control handle 3 to flip the monopolar electric knife component 32 to be vertical upward. At this time, turn on the red dot irradiation lamp 33 so that the red light spot can penetrate the body tissue and be displayed on the body surface. Subsequently, the wiring harness 35 is pushed to drive the red dot projected by the red dot irradiation lamp 33 to align with the marked position on the patient's body surface, and then operate the control handle 3 to start the monopolar electric knife component 32. The monopolar electric knife component 32 can use electric cutting to slowly cut the mucosa of the tracheal mucosa, and can stop bleeding while cutting, cut to the subcutaneous part, and cut the skin. At the same time, the bolt 19 can be screwed and rotated, thereby driving the plastic ring 22 to move downward until the two plastic rings 22 restricts and fixes the wire harness 35, thereby preventing the wire harness 35 from continuously moving inside the trachea, and the round rod 20 slides inside the support sleeve 23, so that the plastic ring 22 can be guaranteed to move in a straight line, thereby improving the docking accuracy of the plastic ring 22 and the wire harness 35. Subsequently, when the wire harness end 34 rotates, the plastic ring 22 and the support sleeve 23 can be driven to rotate simultaneously, and the rotating bracket 21 is located in the rotating groove in the inner wall of the guide sleeve 25, so that the support sleeve 23 can be supported to rotate, so that the monopolar electric knife component 32 can stably cut the trachea. When the trachea is cut into an incision of a specified size, the bolt 19 can be screwed and rotated to cause the plastic ring 22 to disengage from the wire harness 35, thereby facilitating the removal of the wire harness end 34 from the inside of the trachea. At the same time, the synchronous frame 14 can be moved to The front end is pulled so that the second alignment key 15 can be moved out from under the first alignment key 11, so that the reset spring 8 will drive the supporting base 10 and the absorption nozzle 12 to move downward until the two absorption nozzles 12 are in contact with the outer ring surface of the wiring harness 35, so that the contact block 13 can contact the photoelectric sensor 17 at the same time, and the photoelectric sensor 17 is electrically connected to the external suction device, so that the absorption nozzle 12 can absorb the mucus attached to the wiring harness 35 to prevent the mucus from contaminating other utensils. When the wiring harness 35 is pulled out from between the absorption nozzles 12, the synchronous frame 14 is moved to the rear end until the second alignment key 15 pushes the first alignment key 11 upward again, so that the contact block 13 can be disconnected from the photoelectric sensor 17, so that the external suction device is powered off to avoid energy waste.To complete the work of cutting the trachea from the inside to the outside, when the device is in use, the worm 28 can be screwed to drive the worm wheel 27 to rotate, and the central base shaft 24 is connected to the worm wheel 27, so that when the worm wheel 27 rotates, it can drive the guide sleeve 25 to rotate synchronously until the outlet of the rear end of the harness 35 is aligned with the patient's throat, so that the accuracy of the harness 35 and the throat can be improved. In addition, the self-locking between the worm 28 and the worm wheel 27 can prevent the central base shaft 24 from rotating again, and the work is completed. Example 2

[0031] On the basis of Example 1, Figure 8 As shown, the control handle 3 further includes a latch key 36 and a protective cover 37 . The latch key 36 is slidably inserted inside the two sides of the control handle 3 , and the protective cover 37 is fixedly mounted on the side end of the latch key 36 away from the control handle 3 .

[0032] When implementing this embodiment, card slots are opened on both sides of the control handle 3 close to the protective cover 37, and the card key 36 can be located in the card slot and slide, thereby supporting the displacement of the protective cover 37 until the protective cover 37 covers the button on the control handle 3, thereby preventing medical staff from accidentally touching the button. In addition, a magnetic sheet is fixedly installed on the end of the protective cover 37 away from the card key 36, and an iron sheet is fixedly installed on the side end of the control handle 3 close to the protective cover 37, so that after the protective cover 37 covers the button, the magnetic sheet on the protective cover 37 can be aligned with the iron sheet, thereby preventing the protective cover 37 from sliding again and completing the work.
