Description

Technical Field

[0001] The invention relates to the technical field of surgical sutures, in particular to a round flat surgical suture and a continuous manufacturing method thereof. Background Art

[0002] Surgical sutures are an important and commonly used consumable in surgical operations, mainly used for suturing hemostasis, tissue suturing, soft tissue connection and repair, etc. Traditional surgical sutures are generally divided into single-strand or multi-strand according to their structure. Regardless of whether they are single-strand or multi-strand sutures, they are usually circular in cross-section due to the limitations of the early mechanical structure.

[0003] Existing circular sutures can achieve their intended ligation and suturing purposes most of the time. However, due to their circular cross-sectional structure, when sutured, the local pressure at the suture connection site is too high, which may cause new cutting damage to the body's soft tissue, affecting the surgical effect or even causing the operation to fail.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a round flat surgical suture and a continuous manufacturing method thereof are proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a round flat surgical suture and a continuous manufacturing method thereof, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a round flat surgical suture, which includes a round head end line and a flat body segment line, and round head end lines are arranged at both ends of the flat body segment line, and the round head end line and the flat body segment line are a woven integrated structure.

[0007] Furthermore, the round-headed end thread is used to pass through the thread hole of a surgical needle or a matching instrument.

[0008] Furthermore, the flat segment line is used to reduce the pressure exerted on the soft tissue during suturing.

[0009] Furthermore, the round-end wire has a length of 5-20 cm and a wire diameter of 0.4-0.8 mm.

[0010] Furthermore, the flat body segment line has a length of 10-100 cm, a width of 1.3-5.0 mm, and a thickness of 0.4-0.8 mm.

[0011] Furthermore, a continuous manufacturing method for round flat surgical sutures is provided, the continuous manufacturing method is implemented by a braiding machine, the braiding machine includes a disc, an electric gear, a first gear, a second gear, a stationary gear set, a spindle slot, a first hydraulic rod and a second hydraulic rod, the surface of the disc is provided with an electric gear, and the first gear is provided on both sides below the electric gear, the left and right sides of the electric gear are provided with a second gear, and the side of the second gear is provided with a stationary gear set, the surfaces of the stationary gear set, the second gear, the first gear and the electric gear are all provided with spindle slots, and a spindle is engaged inside the spindle slot, the bottom of the first gear is rotatably connected to the first hydraulic rod, and the bottom of the second gear is connected to the second hydraulic rod.

[0012] Furthermore, motors are provided at the bottom of the second hydraulic rod and the first hydraulic rod, and the second hydraulic rod and the first hydraulic rod are adjusted in direction by the motors.

[0013] Furthermore, the continuous manufacturing method comprises the following steps:

[0014] Step 1: When weaving the round end line, the first hydraulic rod contracts to make the first gear away from the electric gear, and the second hydraulic rod extends to make the second gear close to the electric gear until the second gear is meshed with the stationary gear set and the electric gear, and a closed moving track is formed between the second gear, the stationary gear set and the electric gear;

[0015] Step 2: The spindle carries the raw material thread and is inserted into the spindle slot. The electric gear rotates to make the second gear and the fixed gear group rotate accordingly, so that the spindle moves along the sides of each gear through the spindle slot in a closed moving track. At the same time, the raw material thread carried by the spindle is released to realize the weaving of the round head thread, thereby obtaining the round head end thread;

[0016] Step 3: After the round end line is knitted, it naturally transitions to the knitting of the flat body segment line. First, the second hydraulic rod is contracted to make the second gear leave the electric gear, and the first hydraulic rod is extended to make the first gear close to the electric gear until the first gear is meshed with the second gear.

[0017] Step 4: Under the rotation of the second gear, the first gear carries the spindle, so that the spindle moves cyclically along the side of the second gear and the first gear stationary gear set, and the spindle does not pass through the electric gear. At this time, the motor at the bottom of the stationary gear set provides power for it, thereby realizing the natural transition of the round end line to the flat segment line.

[0018] Furthermore, the operations of step 1 and step 2 are repeated at the tail end of the flat body segment line to make a natural transition from the flat body segment line to the round head end line, and the continuous manufacture of the round flat surgical suture can be achieved by continuously repeating the operations of step 1 to step 4.

[0019] Furthermore, the actual power supply method of the second hydraulic rod and the first hydraulic rod is not limited to hydraulic drive, and can also be other methods such as compressed air drive.

When the suture is subjected to force, due to its flat belt structure, compared with the existing surgical sutures that are all round headed, the pressure of the round flat surgical suture on the soft tissue under the same suture tension will be reduced by several times, which significantly improves the shortcomings of the circular suture such as cutting damage caused by suturing, and the transition between the round segment and the flat belt segment of the same suture is natural, the fiber is an integral structure, the material is consistent, the biocompatibility is good, and the tensile strength is high.

[0022] 2. The round flat surgical suture and the continuous manufacturing method thereof utilize the movement of the second gear and the first gear to form a closed-loop moving trajectory among the second gear, the electric gear, and the stationary gear set, so that the spindle moves along the closed-loop moving trajectory to weave the round head end line, and then the second gear and the first gear engage with each other through movement, and the second gear leaves the electric gear. At this time, a circular moving trajectory is formed among the second gear, the first gear, and the stationary gear set. At this time, the spindle moves along the circular moving trajectory to weave the flat body segment line, thereby realizing a natural transition from the round head end line to the flat body segment line, changing the current situation that the existing suture weaving machines can only weave round sutures or flat strip sutures, and realizing the continuous manufacturing of the round flat surgical suture, which is beneficial to improving production efficiency.

[0030] The specific operation is as follows: the round flat surgical suture is composed of a round head end line 1 and a flat body segment line 2. The round head end line 1 is 5-20cm long and has a line diameter of 0.4-0.8mm to facilitate passing through a surgical needle or ancillary equipment. The flat body segment line 2 for effective suturing in the middle is in the shape of a flat belt, with a length of 10-100cm, a width of 1.3-5.0mm, and a thickness of 0.4-0.8mm. When the suture is stressed, the flat body segment line 2 has a flat belt structure compared with the existing surgical sutures that are all round headed. Under the influence of force, the pressure of the round flat surgical suture on the soft tissue will be reduced exponentially, which significantly improves the shortcomings of cutting damage caused by the round suture. In addition, the round segment and the flat band segment of the same suture have a natural transition, the fiber is an integral structure, the material is consistent, the biocompatibility is good, and the tensile strength is high. The material of the round flat suture can be pure ultra-high molecular weight polyethylene material, a blended fabric of ultra-high molecular weight polyethylene material and polyester material or absorbable material, or other natural or synthetic polymer materials, without limitation.

[0031] like Figure 3-Figure 4As shown, a continuous manufacturing method of a round flat surgical suture is implemented by a braiding machine 3, which includes a disc 301, an electric gear 302, a first gear 303, a second gear 304, a fixed gear set 305, a spindle slot 306, a first hydraulic rod 307 and a second hydraulic rod 308. The surface of the disc 301 is provided with an electric gear 302, and the first gear 303 is provided on both sides below the electric gear 302, the left and right sides of the electric gear 302 are provided with a second gear 304, and the side of the second gear 304 is provided with a fixed gear set 305, and the fixed gear set 307 is provided with a second gear set 308. 05. The surfaces of the second gear 304, the first gear 303 and the electric gear 302 are all provided with a spindle groove 306, and a spindle is clamped inside the spindle groove 306. The bottom of the first gear 303 is rotatably connected to the first hydraulic rod 307, and the bottom of the second gear 304 is connected to the second hydraulic rod 308. The bottoms of the second hydraulic rod 308 and the first hydraulic rod 307 are both provided with motors, and the second hydraulic rod 308 and the first hydraulic rod 307 are adjusted in direction by the motor. The actual power supply method of the second hydraulic rod and the first hydraulic rod is not limited to hydraulic drive, and can also be other methods such as compressed air drive;

[0032] The specific operation is as follows: Step 1: When weaving the round end line 1, the first hydraulic rod 307 contracts to make the first gear 303 away from the electric gear 302, and the second hydraulic rod 308 extends to make the second gear 304 close to the electric gear 302, until the second gear 304 is meshed with the stationary gear set 305 and the electric gear 302, at which time a closed moving track is formed between the second gear 304, the stationary gear set 305 and the electric gear 302, and the closed moving track is in a ring shape;

[0033] Step 2: The spindle carries the raw material thread and is inserted into the spindle slot 306. The electric gear 302 rotates so that the second gear 304 and the fixed gear set 305 rotate accordingly, so that the spindle moves along the sides of each gear through the spindle slot 306 in a closed moving track. At the same time, the raw material thread carried by the spindle is released to realize the weaving of the round head thread, thereby obtaining the round head end thread 1;

[0034] Step 3: After the round end thread 1 is knitted, it naturally transitions to the knitting of the flat body segment thread 2. First, the second hydraulic rod 308 contracts to make the second gear 304 leave the electric gear 302, and the first hydraulic rod 307 extends to make the first gear 303 approach the electric gear 302 until the first gear 303 is meshed with the second gear 304.

[0035] Step 4: Under the rotation of the second gear 304, the first gear 303 carries the spindle, and the first gear 303 does not contact and mesh with the electric gear 302, so that the spindle moves cyclically along the side of the second gear 304, the first gear 303 and the fixed gear set 305, and the spindle does not pass through the electric gear 302. At this time, the motor at the bottom of the fixed gear set 305 provides power for it, thereby realizing the natural transition of the round head end line 1 to the flat body segment line 2. The first hydraulic rod 307 and the second hydraulic rod 308 are rotated by the motor at the bottom to adjust the angles of the first gear 303 and the second gear 304, so that the moving routes of the first gear 303 and the second gear 304 are adjusted, so that the first gear 303, the second gear 304 and the fixed gear set 305 can mesh with each other;

[0036] Repeating the operations of step 1 and step 2 at the tail end of the flat body segment line 2, so that the flat body segment line 2 naturally transitions to the round head end line 1, and continuously repeating the operations of step 1 to step 4 can realize the continuous manufacturing of the round flat surgical suture;

[0037] By utilizing the movement of the second gear 304 and the first gear 303, a closed-loop moving trajectory is formed among the second gear 304, the electric gear 302, and the fixed gear group 305, so that the spindle moves along the closed-loop moving trajectory to weave the round-headed end line 1, and then the second gear 304 and the first gear 303 are meshed by movement, and the second gear 304 leaves the electric gear 302. At this time, a circular moving trajectory is formed among the second gear 304, the first gear 303, and the fixed gear group 305. At this time, the spindle moves along the circular moving trajectory to weave the flat body segment line 2, thereby realizing a natural transition from the round-headed end line 1 to the flat body segment line 2, changing the current situation that the existing suture weaving machines can only weave circular sutures or flat-ribbon sutures, and realizing the continuous manufacturing of the round flat surgical suture, which is beneficial to improving production efficiency.

[0038] In summary, if Figure 2-Figure 4 As shown, the round flat surgical suture and the continuous manufacturing method thereof, when in use, firstly when weaving the round head end line 1, the first hydraulic rod 307 contracts to make the first gear 303 away from the electric gear 302, and the second hydraulic rod 308 extends to make the second gear 304 close to the electric gear 302, until the second gear 304 is meshed with the stationary gear set 305 and the electric gear 302, at which time a closed moving track is formed between the second gear 304, the stationary gear set 305 and the electric gear 302, and the closed moving track is in a ring shape;

[0039] The raw material thread carried by the spindle is inserted into the spindle slot 306, and the electric gear 302 rotates so that the second gear 304 and the fixed gear set 305 rotate accordingly, so that the spindle moves along the sides of each gear through the spindle slot 306 in a closed moving track, and at the same time, the raw material thread carried by the spindle is released to realize the weaving of the round head thread, thereby obtaining the round head end thread 1;

[0040] After the round end thread 1 is knitted, it naturally transitions to the knitting of the flat segment thread 2. First, the second hydraulic rod 308 contracts to make the second gear 304 leave the electric gear 302, and the first hydraulic rod 307 extends to make the first gear 303 approach the electric gear 302 until the first gear 303 is meshed with the second gear 304.

[0041] Under the rotation of the second gear 304, the first gear 303 carries the spindle, and the first gear 303 does not contact and mesh with the electric gear 302, so that the spindle moves cyclically along the side of the second gear 304, the first gear 303 and the fixed gear set 305, and the spindle does not pass through the electric gear 302. At this time, the motor at the bottom of the fixed gear set 305 provides power for it, thereby realizing the natural transition of the round head end line 1 to the flat body segment line 2. The first hydraulic rod 307 and the second hydraulic rod 308 are rotated by the motor at the bottom to adjust the angles of the first gear 303 and the second gear 304, so that the moving routes of the first gear 303 and the second gear 304 are adjusted, so that the first gear 303, the second gear 304 and the fixed gear set 305 can mesh with each other;

[0042] Repeat the above operation at the tail end of the flat body segment line 2, so that the flat body segment line 2 naturally transitions to the round head end line 1, and the above operation can be continuously repeated to achieve the continuous manufacturing of the round flat surgical suture;

[0043] The round flat surgical suture consists of a round head end line 1 and a flat body segment line 2. The round head end line 1 is 5-20 cm long and has a line diameter of 0.4-0.8 mm to facilitate the passage of a surgical needle or a supporting instrument. The flat body segment line 2 for effective suturing in the middle is in the shape of a flat belt, with a length of 10-100 cm, a width of 1.3-5.0 mm, and a thickness of 0.4-0.8 mm. When the suture is subjected to force, the flat belt structure of the flat body segment line 2 is compared with the existing surgical sutures that are all round headed. Under the same suture tension, the pressure of the round flat surgical suture on the soft tissue will be reduced by several times, which significantly improves the shortcomings of cutting damage caused by suturing with round sutures. In addition, the round segment and the flat belt segment of the same suture have a natural transition, the fiber is an integral structure, the material is consistent, the biocompatibility is good, and the tensile strength is high.
