Embodiment Construction
[0032] Refer to attached Figure 1~12 , The anastomotic cutting assembly of the tubular stapler includes an anvil seat assembly, a staple cartridge assembly and a puncture connection shaft.
[0033] When the nail anvil assembly is matched with the nail cartridge assembly, the anastomotic surface is a bevel, and the angle of the anastomotic surface slope is 10° to 60°. Clip reed 3, positioning shaft 4, abutment seat 5 and shim ring 6. The positioning shaft 4 is installed on the center hole of the nail anvil 5, and the nail anvil 5 forms an inclination angle with the positioning shaft 4, and the inclination angle is 10°~60°. In the inner hole, a positioning boss 1-1 is arranged on the cap 1 of the nail abutment seat, the cap 1 of the nail abutment seat covers the upper end surface of the nail abutment seat 5, and the spacer ring 6 is installed in the inner hole at the lower end of the nail abutment seat 5.

The invention discloses a coincident cutting assembly of a cannular anastomat, and relates to a digestive tract reconstruction operative instrument. The coincident cutting assembly is suitable for being used in cooperation with the cannular anastomat, is used for end-end coinciding, end-side coinciding and side-side coinciding of the digestive tracts in operations for reconstructing the digestive tracts such as the esophagus, the stomach and the intestines, and comprises a nail abutting-against base assembly, a nail bin assembly and a puncturing connecting shaft. When the nail abutting-against base assembly is coincided with the nail bin assembly, the coincided face is a slope, and the slope angle of the coincided face ranges from 10 degrees to 60 degrees. The nail abutting-against base assembly comprises a nail abutting-against base cover, a left clamping reed, a right clamping reed, a positioning shaft, a nail abutting-against base and a cushion cutter ring. The nail bin assembly comprises a nail bin protective cover, a nail bin, an annular cutter, a nail pushing sheet, a nail bin sleeve and coincided nails, the upper portion of the nail bin sleeve is upwards slant by 10 degrees to 60 degrees with the horizontal plane as the standard, installation holes are formed in the lower bottom of the annular cutter, distribution of the installation holes is coincident with that of annular cutter installation bosses on the nail pushing sheet, the top end of the positioning shaft is provided with a clamping reed installation platform, and the left clamping reed and the right clamping reed form a set to be inserted into a clamping reed installation hole of the positioning shaft.
Description
technical field [0001] The tubular stapler anastomosis assembly of the present invention relates to a surgical instrument for digestive tract reconstruction, which is suitable for use with tubular staplers, and is used for end-to-end, end-to-end, and end-to-end connections of the digestive tract in digestive tract reconstruction operations such as esophagus, stomach, and intestines, etc. Side to side anastomosis. Background technique [0002] The current digestive tract reconstruction surgery uses a tubular digestive tract stapler. The intestinal canal to be resected is anastomosed through two circles of staggered titanium nails on the tubular digestive tract stapler. At the same time, the excess tissue is removed by a circular knife. However, the anastomotic parts of the general tubular digestive tract stapler are flat-headed. After the anastomosis, a circle of inelastic connection scars is formed on the inner wall of the intestine, which causes the stenosis of the intestin...
