[0002] Otolaryngology is a medical specialty that specializes in the diagnosis and treatment of ear, nose, and throat diseases. When removing foreign objects from the patient's ear canal, it is usually necessary to use foreign body forceps to reach into the patient's ear canal for clamping. This is more common in otolaryngology medical treatment. Prior art includes a utility model with publication number CN220309176U, which discloses a foreign body removal device for otolaryngology, comprising a plate body, an inner cavity being arranged inside the plate body, the bottom of the inner cavity extending through the bottom of the plate body, a guide opening being provided on an inner wall of one side of the inner cavity near the top edge, a pull-out plate being slidably connected inside the guide opening, one side of the pull-out plate extending to one side of the plate body, one side of the guide opening extending through one side of the plate body, an incomplete gear being rotatably connected inside the inner cavity through a rotating shaft, a plurality of teeth being equidistantly fixed on the bottom of the pull-out plate near one side edge, the utility model solves the problem that, when removing foreign bodies from the patient's ear canal, it is usually necessary to use pliers to extend into the patient's ear canal for clamping, but when the outer surface of the object is arc-shaped and it is inconvenient to clamp, it will be very difficult to remove, and in severe cases, surgery is required to cut the ear canal open before the foreign bodies can be removed.

[0003] It was found in the use of foreign body forceps in otolaryngology that during the operation of the foreign body forceps, the operator needs to accurately control the forceps to ensure that the patient's tissue is not damaged when removing the foreign body. Long-term use can easily cause wear on the surface of the forceps handle, and at the same time cause the operator's finger joints to be unable to firmly clamp and limit the position.

Preferably, a pull ring is fixedly connected to one end of the restraint belt away from the fixing frame, and the cross-sectional size of the pull ring is adapted to the cross-sectional size of the restraint belt.

[0012] The effect achieved by the above components is that during the process of restraining and limiting the restraint belt, the pull ring can be used to assist in stretching, moving and adjusting.

[0013] Preferably, the restraining belt is a polyester belt, and the length of the restraining belt is matched with the length of the first clamp handle.

[0014] The effects achieved by the above components are: the polyester material of the restraint belt has a certain elasticity, and the polyester material has high strength and good wear resistance, and can be operated and used for a long time.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the utility model, in medical otolaryngology treatment, foreign body forceps are usually used to clamp foreign bodies on the patient's ear, nose and throat. However, if the foreign body forceps are operated for a long time, the foreign body forceps may easily slip out of the hand and cause it to fall. At this time, the sliding frame that moves on the surface of the second forceps handle can be used to drive the limit ring to move its position, so as to facilitate the convenient clamping of the thumb of the medical staff. At the same time, the binding belt in the fixing frame on the surface of the first forceps handle is connected and fixed with the positioning frame on one side. When the binding belt is squeezed and fixed by the rotating shaft and the auxiliary shaft, a friction pad made of rubber material can be used for auxiliary squeezing and limiting. In the process of binding and limiting the binding belt, a pull ring can be used for auxiliary stretching, moving and adjusting. By operating the adjusting device, it is convenient for medical staff to limit the finger joints with the help of the binding belt, and effectively avoid slipping and falling during the use of the foreign body forceps.
