[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0016] like Figure 1-Figure 3 As shown, the present invention proposes a foreign body clamping device for head and neck surgery, comprising a holding shell 1, a transmission assembly, a stainless steel outer tube 11, a rotating inner tube 8 and a clamping end, wherein a push rod 2 is movably provided at one end of the holding shell 1, the push rod 2 is connected to the transmission assembly, the transmission assembly is arranged in the holding shell 1, the stainless steel outer tube 11 is fixedly connected to the other end of the holding shell 1, the rotating inner tube 8 is rotatably arranged in the stainless steel outer tube 11, one end of the rotating inner tube 8 is connected to the transmission assembly, the clamping end is arranged at one end of the stainless steel outer tube 11, the clamping end includes a fixed end 12, a rotating end 13 and a net bag 14, wherein the fixed end 12 is fixedly connected to one end of the stainless steel outer tube 11, the rotating end 13 is fixedly connected to the other end of the rotating inner tube 8, and the net bag 14 is detachably arranged between the fixed end 12 and the rotating end 13.

[0017] A foreign body clamping device for otolaryngology and head and neck with application number CN202221814925.6 (hereinafter referred to as "this patent") adopts the cooperation of movable rods and fan-shaped gears to drive symmetrically arranged clamping blocks for centering clamping to realize foreign body clamping. However, this foreign body grasping method cannot be freely unfolded in very narrow spaces such as children's nasal cavity and ear canal. In addition, the centering clamping grasping method takes up space, and during the opening and merging process, it is easy to bring the risk of secondary damage to the patient's body tissue.

[0018] The net bag winding and wrapping grabbing method adopted by the present invention is more flexible than the central clamping foreign body grabbing method. It is not subject to space restrictions and can be flexibly adjusted in narrow spaces such as the ear canal and nasal cavity, thereby ensuring the removal of foreign objects and personal safety.

[0019] Specifically, when using this device to remove foreign objects, the relevant personnel need to rotate and adjust the rotating end 13 to be close to the fixed end 12, so that the net bag 14 is in a folded and unexpanded state, and then the relevant personnel will insert the stainless steel outer tube 11 into the patient's nasal cavity, ear canal and other narrow spaces, and put the fixed end 12 and the rotating end 13 close to one side of the foreign object. Then the relevant personnel can hold the holding shell 1 and put the palm of the hand on the push rod 2, push the push rod 2 to make it cooperate with the transmission component in the holding shell 1, so that the rotating inner tube 8 rotates in the stainless steel outer tube 11, and then drive the rotating end 13 to rotate, so that the net bag 14 mounted on the rotating end 13 and the fixed end 12 is unfolded and wraps the foreign object to achieve package grabbing. After the grabbing is stable, the relevant personnel can pull out the device to take out the foreign object.

[0020] The cylindrical barrel structure adopted in this patent realizes the removal of foreign objects with one hand, without the need for both hands. When in use, for foreign objects deep in the ear canal or nasal cavity, the external light cannot expose the foreign objects well, and sometimes they cannot even be found. In addition, some foreign objects are deep and need to be well exposed under endoscopy. This device can free up one hand to operate the endoscope for observation, eliminating the situation where foreign objects in deeper positions cannot be found. The existing foreign body clamps require both hands to operate and cannot achieve non-invasive removal of foreign objects in deep positions.

[0021] The present invention realizes that a single person holds a nasal endoscope or an ear endoscope in one hand to expose the foreign body, and holds the removal device with the other hand, places the index finger and the middle finger in the fixed ring to clamp the device, and pushes the push rod 2 forward with the thumb or the palm. The push rod 2 is rigidly connected to the rack 3, and the rack 3 moves forward along the guide rod 10. The linear motion of the rack 3 drives the rotation of the spur gear and the bevel gear, thereby rotating the bevel gear rigidly connected to the internal rod member, thereby causing the rotating end of the clamping end to rotate. When the rotating end rotates to the stop position on the other side of the fixed end and stops, the foreign body will be wrapped in the net bag 14. The device for taking out the wrapped foreign body with one hand realizes the safe and effective removal of foreign bodies from the nasal cavity or ear canal in a very short period of time.

[0022] In summary, the foreign body clamping device for head and neck surgery of the present invention adopts a silicone mesh bag wrapping and grasping method to realize the grasping of foreign bodies in narrow spaces such as the nasal cavity and ear canal. Compared with the clamping method of the transmission instrument, it can be more flexible and versatile, not restricted by the shape of the foreign body, and can realize fast and flexible foreign body grasping, effectively avoiding secondary damage to the human body. By cooperating with the rotating end driven by the rotating inner tube through the fixed end provided on the stainless steel outer tube, the relative rotation of the mesh bag between the rotating end and the fixed end can be realized under the cooperation of the push rod and the transmission assembly, thereby realizing the wrapping of the foreign body by the mesh bag after unfolding, realizing the wrapping and grasping of the foreign body, and realizing the removal of foreign bodies of different shapes in a narrow space.
