[0023] The embodiments of the present invention provide a special tracheal inner cannula removal forceps, as Figure 1-2 shown, including a pliers handle assembly 1, an elastic assembly 2, a rotating assembly 3 and two clamping members 4; the pliers handle assembly 1 includes a first pliers handle 11 and a second pliers handle 12; the first pliers handle 11 and the second pliers handle 12 are arranged oppositely; the elastic assembly 2 is arranged between the first pliers handle 11 and the second pliers handle 12; the two clamping members 4 are arranged oppositely, one ends of the two clamping members 4 are respectively connected to the ends of the first pliers handle 11 and the second pliers handle 12 far from the elastic assembly 2, and the other ends of the two clamping members 4 are configured to abut against the inner cannula. The rotating assembly 3 is arranged between the elastic assembly 2 and the clamping member 4, and both the first pliers handle 11 and the second pliers handle 12 are rotatably connected to the rotating assembly 3.

[0024] Exemplarily, after a medical staff applies a force, one end of the first jaw 11 and the second jaw 12 approaches each other. The elastic component 2 can limit the movement range of the first jaw 11 and the second jaw 12, and increase the clamping force when the clamping member 4 clamps the inner sleeve through the lever principle, so that the clamping member 4 can clamp the inner sleeve more securely.

[0025] Exemplarily, the first jaw 11 and the second jaw 12 can achieve relative rotation through the rotation assembly 3, so as to achieve the technical effect that after the medical staff applies a force, one end of the first jaw 11 and the second jaw 12 approaches each other, and the other end of the first jaw 11 and the second jaw 12 opens for clamping.

[0026] In the embodiment of the present application, as Figure 3 shown, the clamping member 4 includes a clamping portion 41, a mounting portion 42 and a connecting portion 43; one end of the clamping portion 41 is connected to one end of the connecting portion 43, and the outer surface of the clamping portion 41 is configured to fit with the inner surface of the inner sleeve; the other end of the connecting portion 43 is connected to one end of the mounting portion 42, and the other end of the mounting portion 42 is connected to the end of the jaw assembly 1 away from the elastic component 2.

[0027] Exemplarily, during the process of removing the inner sleeve, the medical staff places the clamping portion 41 of the extraction forceps into the inner sleeve to be removed. When the medical staff applies a force to one end of the first jaw 11 and the second jaw 12, the two clamping portions 41 can be opened, so that the outer surface of the clamping portion 41 fits with the inner surface of the inner sleeve. The greater the force applied by the medical staff, the tighter the outer surface of the clamping portion 41 fits with the inner surface of the inner sleeve, so that the inner sleeve can be smoothly removed from the metal sleeve.

[0028] Exemplarily, the outer diameter dimension of the clamping portion 41 is greater than the outer diameter dimension of the connecting portion 43. When the medical staff places the clamping portion 41 into the inner sleeve, the connecting portion 43 will not interfere with the inner sleeve, and the outer surface of the clamping portion 41 can be fully contacted with the inner surface of the inner sleeve, thereby improving the reliability of using the extraction forceps to remove the inner sleeve; the outer diameter dimension of the clamping portion 41 is smaller than the outer diameter dimension of the mounting portion 42. The larger outer diameter dimension of the mounting portion 42 can improve the strength of the clamping member 4, thereby improving the mechanical performance of the extraction forceps.

[0029] In the embodiment of the present application, as Figure 3 shown, a plurality of teeth 5 are provided on the clamping portion 41, and the plurality of teeth 5 are evenly distributed on the surface of the clamping portion 41. The plurality of teeth 5 are configured to increase the friction between the clamping portion 41 and the inner sleeve.

[0030] Exemplarily, when the clamping portion 41 is in contact with the inner sleeve, the contact between the tooth 5 surface and the inner sleeve can improve the friction between the clamping portion 41 and the inner sleeve, thereby improving the reliability of the extraction forceps for extracting the inner sleeve.

[0031] In the embodiment of the present application, as Figure 3-5 shown, the pliers handle assembly 1 further includes a connecting ring 13 and a protrusion 14; the first pliers handle 11 is provided with an avoidance groove; the second pliers handle 12 is fixedly connected to the protrusion 14, and the protrusion 14 cooperates with the avoidance groove; the second pliers handle 12 is provided with an avoidance hole; the first pliers handle 11 is fixedly connected to the connecting ring 13, and the connecting ring 13 cooperates with the avoidance hole.

[0032] Exemplarily, the protrusion 14 is arranged in the avoidance groove and can rotate in the avoidance groove.

[0033] Exemplarily, the protrusion 14 is arranged at the connection between the bent section and the straight section of the first pliers handle 11. During the rotation of the first pliers handle 11 and the second pliers handle 12, they can rotate with the protrusion 14 at this connection as the fulcrum.

[0034] Exemplarily, the connecting ring 13 is arranged at the connection between the bent section and the straight section of the second pliers handle 12. During the rotation of the first pliers handle 11 and the second pliers handle 12, they can rotate with the protrusion 14 at this connection as the fulcrum.

[0035] In the embodiment of the present application, as Figure 3 shown, the rotation assembly 3 includes a rotation shaft 31 and a fixing nut 32; both the protrusion 14 and the connecting ring 13 are provided with through holes; the rotation shaft 31 cooperates with the through holes, and the rotation shaft 31 is configured to rotate in the through holes; both ends of the rotation shaft 31 are fixedly connected with fixing nuts 32, and the fixing nuts 32 respectively abut against the side surfaces of the first pliers handle 11 and the second pliers handle 12.

[0036] Exemplarily, the rotation shaft 31 is arranged in the through hole. Through the rotation shaft 31, the first pliers handle 11 and the second pliers handle 12 can be connected, and both the first pliers handle 11 and the second pliers handle 12 can rotate around the rotation shaft 31. The rotation shaft 31 can be axially limited by fixing nuts 32 at both ends, or a bolt can be used as the rotation shaft 31, and the other end is axially limited by a fixing nut 32. During the installation process, it is necessary to ensure that the first pliers handle 11 and the second pliers handle 12 rotate smoothly without jamming.

[0037] In the embodiment of the present application, as Figure 1-2As shown in the figure, the elastic component 2 includes a first elastic member 21 and a second elastic member 22; a positioning groove is formed at one end of the second elastic member 22 close to the clamping member 4; a clamping strip is arranged at one end of the first elastic member 21 close to the clamping member 4, the clamping strip passes through the positioning groove, and the end face of the first elastic member 21 abuts against the side face of the second elastic member 22; the first elastic member 21 and the second elastic member 22 are arranged oppositely and are respectively fixedly connected to the first pliers handle 11 and the second pliers handle 12.

[0038] Exemplarily, after the medical staff releases the force, the first elastic member 21 and the second elastic member 22 can automatically restore the first pliers handle 11 and the second pliers handle 12 to the original opening and closing state, or a spring can be arranged between the first pliers handle 11 and the second pliers handle 12 to act as the elastic component 2.

[0039] The contact surface between the extraction forceps of the present application and the inner sleeve is small, which will not cause scratches on the inner sleeve, and during the clamping process, the inner sleeve is evenly stressed; wherein, both clamping members 4 can clamp the inner sleeve, making it not easy for the inner sleeve to fall off, thereby reducing the difficulty of disassembling the inner sleeve in clinical work and reducing the discomfort of the patient. Practical operations prove that the extraction forceps of the present application can smoothly extract the inner sleeve.
