Abstract

The invention discloses a rongeur. The rongeur mainly comprises a movable front handle and a fixed rear handle, wherein a front spring piece fixed on the movable front handle is hinged to a rear spring piece fixed on the fixed rear handle; one end of the movable front handle is fixedly connected with the fixed rear handle through screws, so that the movable front handle can move from left to rightrelative to the fixed rear handle; a connecting rod is arranged at the front end of the fixed rear handle; a fixed front edge opening is formed in the front end part of the connecting rod; a push rodis arranged above the connecting rod; the push rod is connected with the movable front handle and can move from left to right relative to the connecting rod; a movable rear edge opening is formed inthe front end part of the push rod; the fixed front edge opening can mutually cooperate with the movable rear edge opening; and a bone returning needle is arranged in the push rod. According to the rongeur disclosed by the invention, superstrong resecting capacity is guaranteed, the situation that when rongeur pieces are opened, resected substances can naturally drop is also realized, the surgerycan be continuously and smoothly operated, and the rongeur has obvious assisting effects on shortening surgery time and improving surgery efficiency.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a rongeur. Background technique [0002] Rongeur is a commonly used surgical instrument, which is mainly used in otolaryngology, neurosurgery, orthopedics, and for biting and cutting bone tissue. It is used to remove the hard bone during the nasal skull base surgical approach and tumor exposure. . Existing rongeurs usually require manual operation. When using a rongeur to crush hard bone, the resected bone is easily embedded in the jaws, causing the resected bone to not fall off naturally. If it is not cleaned manually Will reduce the ability to re-excision. Contents of the invention [0003] The object of the present invention is to provide a rongeur to overcome the shortcomings of the prior art. [0004] The object of the present invention is accomplished through the following technical solutions: this rongeur mainly includes a movable front handle, a fixed rear handle, ...
