Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Features of the embodiments described below may be combined with each other without conflict.
Embodiment one:
referring to fig. 1 to 2, the present utility model provides a pair of trachea cannula foreign body forceps, which is used in combination with an endoscope, such as a laryngoscope, for guiding a trachea cannula, wherein the endoscope is provided with a forceps channel 8, and the foreign body forceps are assembled into the forceps channel 8 in use. Specifically, the foreign matter forceps include stay tube 1 and have the mount pad 2 of cavity inner chamber, mount pad 2 have two opposite side seat boards and connect the loading board between two side seat boards, stay tube 1 is suitable for the solid dress on endoscope pincers way 8, loading board on the mount pad 2 rotatably connects on stay tube 1 through miniature bearing, is provided with two opposite installation pivot 20 on the mount pad 2 inner wall, all is provided with adjusting gear 21 on every installation pivot 20, the below that corresponds every adjusting gear 21 on the mount pad 2 all is provided with the rack 24 with it engaged with, the removal of rack 24 can drive adjusting gear 21 rotation. A pair of jaw members 9 is disposed between the two mounting shafts 20, the jaw members 9 are configured to be able to approach or separate from each other to clamp or loosen the foreign matter, a driving mechanism for driving the jaw members 9 to perform a clamping action is disposed in the support tube 1, the driving mechanism includes a pull rod 5 and a link 6, the pull rod 5 is disposed in the support tube 1 so as to be movable in an axial direction, and the link 6 is connected between the jaw members 9 and the pull rod 5. When the clamp is used, if the target foreign matter appears at the periphery of the clamp under the imaging view of the endoscope, the mounting seat 2 can be rotated around the axial direction of the supporting tube 1, and then the pair of clamp members 9 can be rotated to adjust the direction of the clamp head, so that the target foreign matter at the periphery of the clamp can be conveniently grasped, and the operation difficulty is effectively reduced. The adjusting gear 21 can be driven to rotate by moving the rack 24, so that the jaw members are driven to fold and bend by a set angle relative to the support tube 1 in the length direction so as to adapt to the bending radian of the laryngoscope forceps channel 8, and the bending radian of the laryngoscope forceps channel 8 needs to be adaptively adjusted according to different body positions of patients, so that the folding bending angle of the jaw members also needs to be correspondingly adjusted, and further the observation and operation difficulty is reduced.
Here, jaw member 9 may be connected to the inner extending end of mounting shaft 20 extending into mount 2 by a first radial hinge 3, the arrangement of first radial hinge 3 allowing jaw member 9 to oscillate radially about mounting shaft 20 but limiting its rotation in an axial direction about mounting shaft 20. As to the clamping mechanism of the foreign matter pliers, which belongs to a relatively mature technology in the prior art, this embodiment describes one example, and the others are not enumerated any more, as shown in fig. 3, one end of a connecting rod 6 is connected to a pliers component 9 through a second radial hinge 62, the left end of a pull rod 5 can extend into a mounting seat 2, an annular sliding buckle groove 51 is formed on the end of the pull rod 5, a sliding buckle 61 matched with the sliding buckle groove 51 is arranged in the sliding buckle groove 51, and the other end of the connecting rod 6 is connected to the sliding buckle 61 through a hinge. The second radial hinge 62 allows the link 6 to swing in the width direction but restricts the swing in the length direction with respect to the jaw member 9. When the object needs to be clamped, the pull rod 5 is pulled, and the pull rod 5 drives the connecting rod 6 to swing towards the pull rod side, so that the pair of clamp members 9 are pulled relatively close to clamp the object. When the mount 2 rotates around the support tube 1, the link 6 and the jaw 9 also follow the rotation, and the slider 61 of the link 6 moves in the sliding groove 51 in the circumferential direction when the link 6 rotates, that is, the link 5 restricts the movement of the link 6 only in the longitudinal direction or the axial direction, and the degree of freedom thereof is maintained in the circumferential direction.
In this embodiment, a mounting hole is provided at one end, i.e., the right end, of the support tube 1 far away from the mounting seat 2, the right end of the pull rod 5 extends out of the mounting hole of the support tube 1 and is connected with an operation handle 52, a flushing gap is left between the support tube 1 and the pull rod 5, not shown in the figure, a flushing tube 7 bent downward is connected to the lower portion of the right end of the support tube 1, a liquid pump 71 is connected to the lower end of the flushing tube 7, and a flushing valve 72 is provided on the flushing tube 7. When cleaning is required, the liquid pump 71 and the flushing valve 72 are opened, and flushing liquid is ejected from the inner end of the mounting seat 2 through the flushing gap between the support tube 1, the support tube 1 and the pull rod 5 to flush the jaw 9.
As shown in fig. 3 to 4, the support tube 1 is provided with an adjusting slip ring 41, and the adjusting slip ring 41 is connected to the mount 2 and is capable of driving the mount 2 to rotate around the support tube 1. Specifically, a linear chute is arranged at the bottom of the mounting seat 2, a movable seat 23 is arranged in the linear chute, a combining part 42 is arranged below the adjusting slip ring 41, a movable screw 43 is arranged on the combining part 42, one end of the movable seat 23 is connected with the movable screw 43, the movable seat 23 can be driven to move left and right along the linear chute by rotating the movable screw 43, and the rack 24 is arranged on the movable seat 23. Preferably, the moving screw 43 is disposed in parallel with the support tube 1, and a knob 44 for facilitating a rotation operation is connected to one end of the moving screw 43.
In this embodiment, the jaw 9 includes a body 91, a jaw 92 and a jaw 93 integrally connected, where the jaw 92 is an annular jaw and is located at one end of the body 91, the jaw 93 is located at the other end of the body 91, and the jaw 93 is connected to the corresponding mounting shaft 20. In addition, the support pipe 1 is provided with an engagement block 45 for attaching the foreign matter forceps to the forceps channel.
The working process of the utility model is as follows:
firstly, the folding bending angle of the jaw members is adjusted according to the requirement, the rotary knob 44 moves the screw 43 to drive the movable seat 23 to move along the linear chute, and the rack 24 on the movable seat 23 drives the adjusting gear 21 to rotate, so that the jaw members 9 are driven to fold and bend by a set angle relative to the support tube 1 in the length direction to adapt to the bending radian of the laryngoscope forceps channel 8, and the observation and operation difficulty is reduced. Furthermore, if the target foreign matter appears at the periphery of the forceps channel in the imaging view of the endoscope, the adjusting slip ring 41 can be rotated, so that the mounting seat 2 is driven to rotate around the axis direction of the supporting tube 1, the pair of forceps members 9 are rotated, the angle position of the forceps head in the periphery of the forceps channel 8 is adjusted, the target foreign matter at the periphery of the forceps channel is conveniently grasped, and the operation difficulty is effectively reduced. The adjusting slip ring 41 in the present embodiment is provided in a pair along the length direction of the support pipe 1 to make the overall structure stable and reliable. Furthermore, by pulling the operation handle 52, the link 5 moves to drive the link 6 to swing toward the link, thereby pulling the pair of jaw members 9 relatively close to each other to clamp the target object, and the foreign matter is taken out along the jaw path 8 to complete the foreign matter gripping process.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
