Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a cricothyroid membrane puncture device and a cricothyroid membrane puncture method. Background Art

[0002] The cricothyroid membrane is an elastic conical connective tissue membrane located between the thyroid cartilage and the cricoid cartilage. It is covered with skin on its surface, but contains a small amount of connective tissue fibers and abundant elastic fibers inside. These characteristics endow the cricothyroid membrane with certain elasticity and toughness in the laryngeal structure. Cricothyroid membrane puncture is one of the first-aid methods clinically used for patients with airway obstruction and severe dyspnea. Cricothyroid membrane puncture is mainly applicable to acute upper airway obstruction, such as laryngeal obstruction caused by allergy, neck trauma, laryngitis, laryngeal tumors, etc., especially when the patient's life is threatened and an artificial airway or other emergency airway cannot be effectively established.

[0003] In the prior art, during cricothyroid membrane puncture, steps such as needle puncture, guide wire insertion, and tracheal intubation are required. After each step is completed, medical staff need to constantly replace relevant medical components, and position location needs to be performed multiple times. The puncture time is long, which affects the treatment effect of patients. Therefore, it is necessary to propose a cricothyroid membrane puncture device and a cricothyroid membrane puncture method. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks in the prior art that during cricothyroid membrane puncture, steps such as needle puncture, guide wire insertion, and tracheal intubation are required. After each step is completed, medical staff need to constantly replace relevant medical components, and position location needs to be performed multiple times. The puncture time is long, which affects the treatment effect of patients, and to propose a cricothyroid membrane puncture device and a cricothyroid membrane puncture method.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cricothyroid membrane puncture device includes a housing. An intermittent transmission mechanism is arranged inside the housing. The intermittent transmission mechanism includes a drive motor arranged outside the housing. The output end of the drive motor is provided with a circular ring plate. A convex rod is fixedly connected to the side of the circular ring plate. A triangular convex rod is arranged below the convex rod. A connecting rod is fixedly connected to the side of the triangular convex rod away from the convex rod. A triangular plate is fixedly connected to the side of the connecting rod away from the triangular convex rod. A stapler assembly is arranged on the side of the triangular plate. A puncture needle is arranged on the side of the stapler assembly away from the triangular plate. A metal guide wire is arranged on the side of the triangular plate close to the puncture needle. A hydraulic rod is arranged on the side of the triangular plate close to the precipitation assembly. A tracheal cannula is arranged on the side of the hydraulic rod away from the triangular plate. The drive motor drives the convex rod to move in a circular motion through the circular ring plate. The convex rod drives the connecting rod to rotate through the triangular convex rod. The connecting rod drives the stapler assembly and the puncture needle to move through the triangular plate. The connecting rod drives the metal guide wire to move through the triangular plate. The connecting rod drives the hydraulic rod and the tracheal cannula to move through the triangular plate. The puncture needle, the metal guide wire and the tracheal cannula move intermittently in sequence.

[0007] Among them, the stapler assembly punctures the puncture needle into the cricothyroid membrane of the patient. The precipitation assembly controls the metal guide wire to pass through the puncture needle and enter the cricothyroid membrane. The hydraulic rod controls the tracheal cannula to expand the air hole for opening.

[0008] The above technical solution further includes:

[0009] A mounting plate is fixedly connected to the side of the housing close to the drive motor. The drive motor is fixedly installed on the side of the mounting plate. An arc plate is rotatably connected to the side of the triangular convex rod close to the connecting rod. The arc plate is slidably connected with the circular ring plate.

[0010] A fixing plate is fixedly connected to the side of the triangular convex rod close to the connecting rod. The fixing plate is rotatably connected with the circular ring plate.

[0011] A precipitation assembly is arranged on the side of the triangular plate close to the stapler assembly. The metal guide wire is arranged at the output end of the precipitation assembly

[0012] An air pump is fixedly connected to the side of the mounting plate. An annular hose is arranged at the output end of the air pump. A base is fixedly connected to the side of the annular hose close to the hydraulic rod. An airbag is fixedly connected to the side of the base close to the tracheal cannula.

[0017] A cricothyroid puncture method, which is implemented based on the aforementioned cricothyroid puncture device of the present invention, includes the following steps:

[0018] Step 1: Start the intermittent transmission mechanism provided inside the housing. The drive motor in the intermittent transmission mechanism starts to operate, and the drive motor controls the circular ring plate to rotate when it operates.

[0019] Step 2: When the circular ring plate rotates, it drives the convex rod to rotate in a circular motion. When the convex rod rotates one week, it drives the triangular convex rod to rotate one-third. The triangular convex rod drives the triangular plate to rotate through the connecting rod.

[0020] Step 3: After the nail gun assembly and the puncture needle are operated, they rotate one-third by using the connecting rod. The connecting rod drives the precipitation assembly and the metal guide wire to move to the central position through the triangular plate. After the precipitation assembly and the metal guide wire are operated, they rotate one-third by using the connecting rod.

A puncture needle 12 is arranged on the side of the stapler assembly 11 away from the triangular plate 10. A metal guide wire 14 is arranged on the side of the triangular plate 10 close to the puncture needle 12. A hydraulic rod 15 is arranged on the side of the triangular plate 10 close to the precipitation assembly 13. A tracheal cannula 16 is arranged on the side of the hydraulic rod 15 away from the triangular plate 10. The driving motor 3 drives the convex rod 5 to move in a circular motion through the circular ring plate 4. The convex rod 5 drives the connecting rod 9 to rotate through the triangular convex rod 6. The connecting rod 9 drives the stapler assembly 11 and the puncture needle 12 to move through the triangular plate 10. The connecting rod 9 drives the metal guide wire 14 to move through the triangular plate 10. The connecting rod 9 drives the hydraulic rod 15 and the tracheal cannula 16 to move through the triangular plate 10. The puncture needle 12, the metal guide wire 14, and the tracheal cannula 16 move intermittently in sequence.

[0036] A mounting plate 2 is fixedly connected to the side of the housing 1 close to the driving motor 3. The driving motor 3 is fixedly installed on the side of the mounting plate 2. An arc plate 7 is rotatably connected to the side of the triangular convex rod 6 close to the connecting rod 9. The arc plate 7 is slidably connected to the circular ring plate 4.

[0037] A precipitation assembly 13 is arranged on the side of the triangular plate 10 close to the stapler assembly 11. The metal guide wire 14 is arranged at the output end of the precipitation assembly 13.

[0038] An air pump 17 is fixedly connected to the side of the mounting plate 2. The output end of the air pump 17 is provided with an annular hose 18. A base 19 is fixedly connected to the side of the annular hose 18 close to the hydraulic rod 15. An airbag 20 is fixedly connected to the side of the base 19 close to the tracheal cannula 16. The base 19 is fixedly connected to the hydraulic rod 15. The tracheal cannula 16 is arranged inside the airbag 20 and is wrapped.

[0039] An ultrasonic locator 22 is arranged on the side of the housing 1. An ultrasonic probe 23 for transmitting and receiving ultrasonic waves is arranged on the side of the ultrasonic locator 22 away from the housing 1.

[0040] In this embodiment, when the patient needs to use the device, medical staff can use the ultrasonic locator 22 provided on the side of the housing 1 for ultrasonic positioning. The ultrasonic wave is transmitted by the ultrasonic probe 23 provided on the side of the ultrasonic locator 22 to quickly complete the positioning of the puncture position. At this time, the staple gun assembly 11 and the puncture needle 12 are above the positioning position. The staple gun assembly 11 is used to drive the puncture needle 12 to puncture into the cricothyroid membrane. At this time, the intermittent transmission mechanism provided inside the housing 1 is started. There is a mounting plate 2 fixedly connected inside the housing 1, and the driving motor 3 fixedly installed on the side of the mounting plate 2 starts to operate. When the driving motor 3 operates, it starts to control the circular plate 4 provided at its output end to rotate.
