Description

Straight peen " V " shape is chewed rongeur

This utility model relates to a kind of improvement of rongeur, and specifically a kind of straight peen " V " shape is chewed rongeur, is applicable to that the cervical vertebra single open-door stings door-hinge side " V " shape bone groove operation.

Used clinically at present rongeur, be generally ellipse or " U " clamp is chewed, sting door-hinge side " V " shape bone groove when operation doing the cervical vertebra single open-door, " V " shape groove difference of being stung is bigger, sutura can not be tightly involutory when opening the door, prolonged operating time, influenced the sclerotin healing of postoperative patient, brought big painful to patient.

The purpose of this utility model is to provide a kind of and shortens operating time, be beneficial to sclerotin healing, can once finish the cervical vertebra single open-door stings straight peen " V " shape of door-hinge side " V " shape bone groove operation and chews rongeur.

This utility model is achieved in that this straight peen " V " shape is chewed rongeur, by a left side, right binding clip body, and with a left side, the pincers handle and the interlock pliers grip of right binding clip bulk phase correspondence constitute, between the interlock pliers grip, be provided with spring, interlock pliers grip head is connected with turning cylinder with the pincers handle, binding clip body inboard is a smooth flat, on a left side, " V " shape blade is established in the end of right binding clip body, " V " shape top of " V " shape blade and a left side, right binding clip end of body overlaps, the inboard smooth flat of the vertical binding clip body of sword face of " V " shape blade, and be arranged on a left side, right binding clip end of body dual-side is along last.The knife height of " V " shape blade on the left and right binding clip body is 2mm, and " V " shape limit sword length is 5mm, and " V " shape limit angle α is 45 °.When using this utility model, grasp the interlock pliers grip, the binding clip body aim at the cervical vertebra both sides respectively progressively sting out " V " shape bone groove, make half neck bone of disconnection rotate miter angle then, make " V " shape bone groove both sides closure of a side.

The utility model has the advantages that: compare with used rongeur, can finish the cervical vertebra single open-door once and sting the operation of door-hinge side " V " shape bone groove, and the bone trough rim is along smooth neat, be beneficial to the postoperative patient sclerotin healing, shorten operating time, alleviated patient's misery, easy to use flexible.
