Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a mounting forceps for artificial ossicles. Background Art

[0002] In the prior art, the human ear mainly hears sounds through air conduction. After the sound reaches the human ear, the transmission channels are the external auditory canal, tympanic membrane, auditory ossicles, and inner ear. The auditory ossicles include the malleus, incus, and stapes. The ossicular chain is deformed or damaged, resulting in sound transmission dysfunction, which needs to be replaced with artificial auditory ossicles. In the artificial auditory ossicular installation surgery, it is usually necessary to use artificial auditory ossicular installation forceps to clamp the artificial auditory ossicles. The clamping part of the existing artificial auditory ossicular installation forceps, that is, the grain forceps, opens and closes in the shape of an crocodile mouth. The opening angles of the clamping part are different when clamping the artificial auditory ossicles at different positions, and the opening angle of the clamp handle will also change accordingly. The surgeon needs to adjust the size of the hand opening, which requires an adjustment and adaptation process. In addition, the clamping part opens to both sides when releasing the artificial auditory ossicles, which may touch other parts of the inner ear, and there is a possibility of bruising or scratching the inner ear.

[0003] The Chinese utility model patent with application number: 201821860033.3 discloses an artificial ossicular installation pliers, including a pliers handle and a pliers body, the pliers handle as a whole extends longitudinally, and the pliers body as a whole extends laterally; the pliers handle includes a left handle and a right handle, and the left handle and the right handle are connected by a rotating shaft; the pliers body includes an upper pliers body and a lower pliers body, both of which are provided with two ends, the lower pliers body is provided with a guide rail, the guide rail extends laterally, and the upper pliers body is connected to the guide rail; the right end of the lower pliers body is fixedly connected to the upper end of the right handle; the upper end of the left handle is provided with a slide groove, and the slide groove is inclined to the right side; the right end of the upper pliers body is provided with a connecting shaft along the thickness direction, and the connecting shaft is located in the slide groove; the left end of the upper pliers body is provided with a first clamping part, and the left end of the lower pliers body is provided with a second clamping part, and the laterally opposite surfaces of the first clamping part and the second clamping part are parallel to each other. However, this type of artificial ossicular installation forceps can only clamp and install the artificial ossicular bones through the clamping part. Due to the small size of the clamping part, it is difficult to clamp the artificial ossicular bones, which makes it difficult for the doctor to operate and is inconvenient for the user to perform the clamping operation. Moreover, it only has a clamping function and its usage is relatively single. It cannot meet the user's other operation needs during the operation and has certain usage limitations.
