Description

Technical Field

[0001] The utility model relates to the technical field of tubular staplers, in particular to an anvil seat device for a tubular stapler. Background Art

[0002] The anvil and the knife ring of the tubular stapler in the prior art are integral, and there is no change after the tubular stapler is actuated, so that the operator does not know whether the tissue to be cut has been cut, which is very inconvenient to use. In addition, after the tissue is cut, it is not easy to remove the anvil from the cut anastomotic stoma of the tubular stapler in the prior art. If it is forcibly removed, the anastomotic stoma will be enlarged, which is easy to cause bleeding.

[0003] After searching, Chinese patent number CN208524945U discloses a tube-type stapler anvil device, which includes an anvil fixing assembly and an anvil seat, wherein the anvil fixing assembly has an anvil fixing plate; the anvil seat includes a left anvil seat and a right anvil seat that are enclosed to form the anvil seat, wherein the left anvil seat and the right anvil seat are hinged together, a limiting mechanism is connected between the anvil seat and the anvil seat fixing plate, and elastic members are respectively connected between the left anvil seat and the anvil seat fixing plate and between the right anvil seat and the anvil seat fixing plate, wherein a left washer ring is arranged in the left anvil seat, and a right washer ring is arranged in the right anvil seat, wherein the left washer ring and the right washer ring are enclosed to form a washer ring. The utility model not only enables the operator to clearly know that the tissue has been cut, but also facilitates the removal of the anvil seat from the cut anastomotic opening after the operation of the tube-type stapler is completed.

[0004] However, in actual use, the above device can only be installed and used in one direction. Once the nail groove inside the nail seat is damaged, the above device needs to be discarded directly and cannot be used again, which reduces the utilization rate of the device and increases the subsequent use cost of the device.

[0012] Compared with the related art, the anvil device for a tubular stapler provided by the utility model has the following beneficial effects:

[0013] The utility model provides a pin holder device for a tubular anastomosis device, which realizes position adjustment of the pin holder disk by arranging a position adjustment of a threaded connection ring on an external threaded strip at a center position, thereby controlling the protruding length of the two-way connecting rod.
