[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] The biological patch used with a combined stapler requires an incision at each end to allow the stapler's anvil and cartridge to pass through, pre-fixing the patch to the stapler. For example... Figure 2 As shown, a cut is made at a specific position on the rectangular biological patch 6 to obtain a cut 7; the cut 7 generally needs to be at a specific position on the biological patch 7, at an appropriate distance from the top and bottom edges, and centered horizontally.

[0025] Therefore, in order to cut the incision 7 on the biological patch 6 more efficiently and accurately; such as Figure 1 As shown, this application provides a biological patch production cutting auxiliary positioning device, including a main body plate 1, a positioning part 2 and a cutting part 3, wherein the positioning part 2 and the cutting part 3 penetrate the main body plate 1;

[0026] The main body plate 1 is made of a material that is not easily damaged, shed, or deformed; preferably, the main body plate is made of stainless steel. The main body plate 1 does not deform, thus maintaining its fit with the biological patch 6 and avoiding cutting errors caused by device malfunctions. The positioning part 2 and the cutting part 3 are mounted on the main body plate 1, penetrating through it. The positioning part 2 primarily serves as a positioning window for observation, while the cutting part 3 is used for cutting.

[0027] The positions of the positioning part 2 and the cutting part 3 should be determined according to the position of the cutting incision 7 on the biological patch 6 as needed. Figure 1 As shown, the positioning part 2 includes a first positioning part 21 and a second positioning part 22, and an alignment line segment 5 is provided between the first positioning part 21 and the second positioning part 22; the width side 61 of the biological patch 6 shares a common perpendicular line with the alignment line segment 5, and the endpoints of the width side 61 of the biological patch 6 are respectively inside the first positioning part 21 and the second positioning part 22.

[0028] The alignment segment 5 is a line segment formed by connecting two points on the edges of the two parts between the first positioning part 21 and the second positioning part 22. In one embodiment, the alignment segment 5 can be extended, with the extension line passing through the first positioning part 21 and the second positioning part 22 and extending thereafter. In this way, the wide side 61 of the biological patch 6 coincides with the alignment segment 5, thus fixing the position of the biological patch 6 in the longitudinal direction.

[0029] In order to enable the biological patch 6 to be fixed in the transverse direction, the width side 61 of the biological patch 6 is aligned with the perpendicular bisector of the alignment line segment 5, so that the biological patch 6 is aligned based on the perpendicular bisector of the alignment line segment 5 and is positioned in the transverse direction.

[0030] In one embodiment, the end points of the width side 61 of the biological patch 6 are respectively in the first positioning part 21 and the second positioning part 22. Further comprising an observation scale line 4 parallel to the alignment line segment 5.

[0031] Since the first positioning part 21 and the second positioning part 22 are observation windows, further comprising an observation scale line 4 parallel to the alignment line segment 5. Therefore, when the end points of the width side 61 of the biological patch 6 are respectively in the first positioning part 21 and the second positioning part 22, the positions of the end points can be observed, and further according to the positions of the end points, the scale of the positions of the end points on the observation scale line 4 is determined to determine whether the width side 61 of the biological patch 6 is aligned left and right of the alignment line segment 5.

[0032] In one embodiment, the scale on the observation scale line 4 is set according to the length of the width side 61 of the biological patch 6. On the observation scale line 4, the intersection of the perpendicular bisector of the alignment line segment 5 and the observation scale line 4 is taken as the center, and on both sides of the center, the observation scale line 4 is marked with scale marks according to 1 / 2 of the length of the width side 61 of the biological patch 6, that is, when the end points of the width side 61 of the biological patch 6 are at the scale mark points, the length on the side is half of the width side 61.

[0033] In one embodiment, the observation scale line 4 is provided with uniform scales, and the perpendicular bisector of the alignment line segment 5 passes through one scale on the observation scale line 4. The perpendicular bisector of the alignment line segment 5 passes through one scale on the observation scale line 4. Since both sides are uniform scales, whether the number of scales on the left and right sides is the same can be used to determine whether the lengths on the left and right sides are the same.

[0034] In one embodiment, the observation scale line 4 is provided with uniform scales, and the scale value is marked. The length of the left and right ends can be determined by directly reading the scale value, so that the left and right lengths are adjusted to be the same. For example, the observation scale line 4 is parallel to the alignment line segment 5, the scale reading of the intersection of the perpendicular bisector of the alignment line segment 5 and the observation scale line 4 is a, the reading of the observation scale line 4 at the position of the end point in the first positioning part 21 is b, and the reading of the observation scale line 4 at the position of the other end point in the second positioning part 22 is c. If |b-a|=|a-c|, it indicates that the width side 61 of the biological patch 6 is aligned left and right of the alignment line segment 5.

[0035] In one embodiment, the scale 0 on the observation scale line 4 is the scale through which the perpendicular bisector of the alignment line segment 5 passes.

[0036] In an embodiment, the uniform scale on the observation scale line 4 is marked with scale values symmetrically about the 0 scale.

[0037] With the setting of the 0 scale and other symmetric scales, it is more convenient to judge whether the left and right lengths are the same.

[0038] In an embodiment, the cutting part 3 is the same in size and shape as the incision 7 of the biological patch 6.

[0039] In an embodiment, the distance from the cutting part 3 to the alignment line segment 5 is the distance from the incision 7 of the biological patch 6 to the width side 61 of the biological patch 6.

[0040] The perpendicular distance from the cutting part 3 to the alignment line segment 5 is the distance from the incision 7 of the biological patch 6 to the width side 61 of the biological patch 6. Therefore, the position of the cutting part 3 can be adjusted according to the actual incision position. And the cutting part 3 is adjusted to be the same in size and shape as the incision 7 of the biological patch 6.

[0041] In an embodiment, the first positioning part 21 and the second positioning part 22 are the same in shape. The same shape of the positioning part is conducive to observation.

[0042] In an embodiment, the first positioning part 21 and the second positioning part 22 are the same square; the first positioning part 21 and the second positioning part 22 are symmetric about the perpendicular bisector of the alignment line segment 5; and the observation scale line 4 is arranged on the side of the square parallel to the alignment line segment 5.

[0043] The first positioning part 21 and the second positioning part 22 are the same square; the first positioning part 21 and the second positioning part 22 are symmetric about the perpendicular bisector of the alignment line segment 5; and the observation scale line 4 is arranged on the side of the square parallel to the alignment line segment 5. This is more conducive to the observation of the width side 61 of the biological patch 6 in the first positioning part 21 and the second positioning part 22.

[0044] In an embodiment, as Figure 3 ; the device main plate is made of stainless steel material, the horizontal distance from the alignment line segment to the cutting part is 5 mm, the cutting window is 10 mm long, and the observation scale line is symmetrically marked with 10 mm intervals to 30 mm;

[0045] The operation process of preparing a biological patch with an incision length of 10 mm and a distance of 5 mm from the top end and in the middle left and right is as follows:

[0046] Place the 30mm x 60mm biological patch flat, place the above device on the biological patch, make the width side of the biological patch coincide with the alignment segment, adjust the position of the device left and right, observe the scale reading of the left and right sides of the biological patch, make the scale reading of both ends equal, at this time, cut along the cutting part with a blade, and a biological patch with a 10mm long incision, 5mm from the top end, and in the middle left and right is obtained.
