Abstract
The utility model relates to the technical field of staplers, in particular to a cutting stapler anvil. The cutting stapler anvil comprises an anvil cover, a connecting rod, an anvil body, relief holes, a first clamping slot, a second clamping slot and U-shaped retainer rings, wherein the anvil cover and the connecting rod are integrated, the anvil body is arranged under the anvil cover, the anvil cover is provided with the relief holes, the first clamping slot is arranged in the connecting rod between the anvil cover and the anvil body, the second clamping slot is arranged in the connecting rod under the anvil body, the first clamping slot and the second clamping slot are respectively connected with the U-shaped retainer rings of the anvil cover and the anvil body, and the anvil body is of a hollow structure, and is provided with drainage grooves. The cutting stapler anvil has a simple, compact and reasonable structure, can be conveniently and rapidly assembled and reliably connected, has high machining precision and concentricity, can uniformly remove the overhigh transient pressure of an internal anastomotic stoma, prevent tissue congestion and the poor shaping of pressed staples and greatly enhance the reliability of the operation of a stapler, and is easy to use and popularize.
Description
Technical field
This utility model relates to a kind of technical field of anastomat, especially a kind of Endo-GIA nail anvil.
Background technology
Anastomat is the medical apparatus and instruments in the extensive use surgical operation, and in recent years, along with improving constantly of China's scientific and technological level, the design and fabrication technology of anastomat product makes great progress.Anastomat obtains applying more and more widely at the various operating end ends such as esophagus, Stomach duodenum, colon, rectum, biliary tract, hemorrhoid, distolateral, side to side anastomosis, the replacing manual suture.
Existing Endo-GIA nail anvil machining accuracy is low, and concentricity is poor, has been difficult to get rid of the too high instantaneous pressure of intracavity anastomotic stoma, easily occurs organizing hyperemia and anastomosis staple pressurized aftershaping bad, greatly reduces the reliability of anastomat work.
The utility model content
In order to overcome the deficiency that existing anastomat nail anvil machining accuracy is low, concentricity is poor and the anastomat functional reliability is poor, this utility model provides a kind of Endo-GIA nail anvil.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of Endo-GIA nail anvil, comprise nail anvil lid, connecting rod, nail anvil body, vent holes, draw-in groove one, draw-in groove two and U-shaped back-up ring, the nail anvil lid is one-body molded with connecting rod, nail anvil lid below is provided with the nail anvil body, nail anvil covers and is provided with vent holes, be provided with draw-in groove one in connecting rod between nail anvil lid and nail anvil body, be provided with draw-in groove two in the connecting rod of nail anvil body below, draw-in groove one and draw-in groove two cover and are connected U-shaped back-up ring with the nail anvil body and are connected with nail anvil respectively.
According to another embodiment of the present utility model, comprise that further the nail anvil body is hollow structure, the nail anvil body is provided with drainage trough.
The beneficial effects of the utility model are, this Endo-GIA anvil structure is simple, compact and reasonable, easy to assembly quick, connect reliably, machining accuracy is high, good concentricity, evenly got rid of the too high instantaneous pressure of intracavity anastomotic stoma, avoid organizing hyperemia and anastomosis staple pressurized aftershaping bad, greatly improved the reliability of anastomat work, be easy to use and promote.
