[0035] Embodiment 1:

[0036] Referring to Figure 1 ​The anastomat anvil seat comprises an anvil seat body 1, one end of the anvil seat body 1 is integrally formed with an anvil head 2, and the end of the anvil head 2 away from the anvil seat body 1 is inclined upward along the thickness direction of the anvil seat body 1, so that the anvil seat body 1 and the anvil head 2 have a height difference.

[0037] A plurality of anti-skid stripes 3 are formed on the surface of the anvil head 2, the plurality of anti-skid stripes 3 are arranged at intervals along the length direction of the anvil seat body 1, and the middle part of the anti-skid stripe 3 is outwardly convex as an arc away from the anvil seat body 1.

[0038] An anti-skid groove 4 is arranged between each adjacent two anti-skid stripes 3 on the surface of the anvil head 2, the middle part of the anti-skid groove 4 is outwardly convex as an arc away from the anvil seat body 1, and the anti-skid groove 4 is parallel to the anti-skid stripe 3.

[0039] When the anastomat is used to clamp the tissue, the anvil head 2 with the upwardly inclined end, and the anti-skid stripes 3 and the anti-skid groove 4 on the anvil head 2 increase the resistance between the anvil seat body 1 and the tissue, so that the anastomosis is more accurate.

[0040] With reference to Figure 1 , Figure 2 and Figure 3 , the surface of the anvil seat body 1 is integrally formed with a protrusion 5 on both sides along the width direction of the anvil seat body 1, the protrusion 5 is obliquely installed, the thickness of the protrusion 5 gradually decreases from the position close to the anvil head 2 to the position away from the anvil head 2, and the top of the end with the maximum thickness of the protrusion 5 is a rounded corner 7.

[0041] A plurality of grooves 6 are arranged at intervals along the length direction of each protrusion 5, the groove 6 is composed of a first groove body 61 and a second groove body 62, the end of the first groove body 61 and the second groove body 62 close to each other is connected and forms an included angle, and the included angle between the first groove body 61 and the second groove body 62 is directed to the anvil head 2.

[0042] When the anastomat is used to clamp the tissue, the protrusion 5 on the anvil seat body 1 reduces the contact area between the anvil seat body 1 and the clamped tissue, increases the internal stress on the tissue, so that the anastomat obtains greater clamping force. The grooves 6 on the protrusion 5 increase the friction force between the clamped tissue and the protrusion 5, so that the anastomat clamps the tissue more stably, at the same time, increases the pressure on the tissue, and ensures the anastomosis effect.

[0043] The implementation principle of the anastomat anvil seat of the embodiment is that the anvil head 2 is integrally formed at one end of the anvil seat body 1, the anvil head 2 is inclined upward relative to the surface of the anvil seat body 1, anti-skid stripes 3 are formed on the surface of the anvil head 2, and anti-skid grooves 4 are arranged on the surface of the anvil head 2, so as to increase the resistance between the anvil head 2 and the clamped tissue, and make the anastomosis more accurate.

[0044] Embodiment 2:

[0045] With reference to Figure 4 The difference between the embodiment 2 and the embodiment 1 of the present application is that the anti-skid stripes 3 and the anti-skid grooves 4 are wavy, the wave peak positions of the anti-skid stripes 3 correspond to the wave valley positions of the anti-skid grooves 4 one by one, and the wave valley positions of the anti-skid stripes 3 correspond to the wave peak positions of the anti-skid grooves 4 one by one.

[0046] The implementation principle of the embodiment 2 of the present application is that the wave peak positions of the anti-skid stripes 3 correspond to the wave valley positions of the anti-skid grooves 4, further increasing the clamping resistance, so that the tissues are more easily clamped, and the anastomosis effect is improved.
