The surgical treatment methods are various, and for three-degree partial tearing and full-layer tearing with a tearing opening smaller than 5cm, a suture with a thread anchor is adopted for suturing, in the process, the limitation of minimally invasive wounds is caused, the shape and the angle of the slender tubular thread-passing suture hook are changeable, and the slender tubular thread-passing suture hook needs to be bent at multiple positions.

At present, the main bending methods of the threading suture hook are three types:

the first method comprises the following steps: bending by using a forming die;

and the second method comprises the following steps: bending by using a special numerical control pipe bending machine;

and the third is that: manual bending is used.

At present, the main processing methods of the cutting edge and the sharp corner of the threading sewing hook are two types:

the first method comprises the following steps: after all the bending is finished, manually throwing a cutting edge and a sharp corner on the grinding wheel;

and the second method comprises the following steps: after all the bends are finished, mechanical processing methods such as milling/grinding of edges and sharp corners are used.

As a preferred embodiment, the milling tool 40 includes: the sewing hook comprises a milling tool main body 41, a milling tool pressing plate 42 and a detachable limiting block 43, wherein the detachable limiting block is used for being in contact with the end part of the suture hook blank after wire cutting so as to position the end part of the suture hook blank after wire cutting.

The milling tool body 41 is provided with a milling tool body mounting groove into which the long rod section of the suture hook blank after wire cutting is inserted.

The detachable stopper 43 is detachably attached to the milling tool main body 41. Specifically, the milling tool main body 41 is provided with a stopper positioning groove into which the detachable stopper 43 is inserted. The removable stop block 43 is partially inserted into the stop block positioning groove so that the removable stop block 43 is detachably mounted to the milling tool main body 41.

The mill clamp plate 42 is mounted to the mill body 41 to lock the long stem segment of the wire cut suture hook blank in the mill body mounting slot. Specifically, the milling tool 40 further includes: a rotating shaft screw 44 for rotatably connecting the milling tool pressing plate 42 and the milling tool body 41, and a locking screw 45 for locking the positions of the milling tool pressing plate 42 and the milling tool body 41. The same screws may be used for the spindle screw 44 and the lock screw 45. The spindle screw 44 is fixed to the milling tool body 41 through the milling tool pressing plate 42. The milling fixture pressure plate 42 is provided with a notched groove into which the locking screw 45 is inserted. When the milling tool pressing plate 42 is rotated about the rotary shaft screw 44 relative to the milling tool main body 41, the lock screw 45 can move from inside to outside of the notch groove. After the locking screw 45 is moved out of the notch groove, the finished suture hook blank can be removed when the milling tool pressing plate 42 does not cover the suture hook blank. When the milling fixture pressing plate 42 covers the suture hook blank, the position of the milling fixture pressing plate 42 can be locked by tightening the locking screw 45.

The detachable limiting block 43 fixes the milling fixture pressing plate 42 after positioning the end part of the suture hook blank after the wire cutting. Then the detachable limiting block 43 is taken down, and the end part of the sewing hook blank is milled to machine a sharp-angled cutting edge.

The milling tool 40 is simple and convenient to clamp, can be quickly limited and quickly disassembled, and has good machining cutting edge angle and size consistency.

As a preferred embodiment, the second bending tooling 20 includes: the sewing hook comprises a base 21, an inner locking sleeve 22, an outer locking sleeve 23, a positioning clamping block 24, a movable clamping block 25, a rotating pin 26, a positioning block 27 for mounting to the positioning clamping block 24 to be in contact with the base 21 to limit the position of the positioning clamping block 24, and a detachable stop 28 for abutting against a sharp corner of a sewing hook blank to position the sewing hook blank.

The inner locking sleeve 22 is mounted to the base 21. The inner locking sleeve 22 and the outer locking sleeve 23 are sleeved on the periphery of the long rod section of the sewing hook blank. The locking sleeve 22 is provided with a plurality of jaws for gripping the long stem section of the suture hook blank. The outer locking sleeve 23 and the inner locking sleeve 22 form a threaded connection with the squeeze jaws to grip the long stem section of the suture hook blank. The positioning and movable clamping blocks 24, 25 are rotatably connected to the base 21 by means of a rotation pin 26. The removable stop 28 is removably mounted to the locating gripping block 24.

Specifically, the positioning clamp block 24 and the movable clamp block 25 are each mounted with a long handle 29 for rotation by the user. The second bending tool 20 further includes: inner locking sleeve pressure plate 221. The inner lock sleeve pressure plate 221 fixes the inner lock sleeve 22 to the base 21. The inner lock sleeve presser plate 221 and the base 21 are attached in the same manner as the milling tool presser plate 42 and the milling tool main body 41.

When the second bending tool 20 is used, the non-bent portion of the suture hook blank, i.e., the long rod section, is first passed through the inner locking sleeve 22 and the outer locking sleeve 23. The outer locking sleeve 23 is screwed into the inner locking sleeve 22 but not locked. A removable stop 28 is mounted on the locating and clamping block 24. The detachable stop block 28 can prop against the sharp corner and the cutting edge of the thread-passing sewing hook when being installed on the positioning clamping block 24, thereby playing a role in limiting. After the sharp edge of the suture hook blank abuts the removable stop 28, the outer locking sleeve 23 is tightened to compress the outer conical surface of the inner locking sleeve 22 to grip the suture hook blank. After the positioning is completed, the detachable stopper 28 is removed, and the positioning and clamping block 24 is moved downward by rotating the long handle 29 to the maximum position, i.e. the position where the positioning block 27 is in contact with the base 21. The movable clamping block 25 is then moved downwards by rotating the long handle 29 to be bent. After bending, the bending angle required by the sewing hook is less than or equal to the bending limit angle of the clamp. When the first piece is bent, if the bending angle is too bent, the first piece can be folded back, the two long handles 29 are rotated upwards to be bent to qualified positions, then marks are made on the movable clamping blocks 25, and the qualified position is obtained when the first piece is bent to the marked position every time.

The processing of the sewing hook comprises the following steps:

material picking: taking a slender pipe material;

bending: bending by adopting a first bending tool 10;

wire cutting: clamping the suture hook blank bent by the first bending tool 10 by using a wire cutting tool 30, and then performing wire cutting;

milling: milling a sharp corner of a cutting edge on the end part after the line cutting by using a milling tool 40;

deburring: removing burrs;

bending: a second bending tool 20 is adopted to assist bending which is not in the same plane with the bent bending;

wire cutting: the wire cutting tool 30 is used to clamp the parts and cut the allowance of the non-bent end, namely the long rod section.

Deburring: removing burrs on the cut end face;

cleaning: removing stains on the surface of the product.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
