Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a suture management tool for surgical flat / round flat sutures. Background Technology

[0002] Surgical sutures are mainly classified into round sutures, flat sutures, or round-flat sutures. Round sutures are cylindrical in shape, generally less prone to knotting or tangling, and can more easily penetrate human tissue for suturing. The suture makes linear contact with the tissue, providing some cutting effect. Round-flat sutures are round at both ends and flat in the middle. Flat sutures have a rectangular cross-section throughout. During suturing, flat or round-flat sutures make surface contact with the tissue, greatly reducing the cutting effect on the suture area. Compared to round sutures, flat or round-flat sutures provide a larger footprint contact area (i.e., a larger contact area with the area to be sutured), especially in surgeries such as meniscus repair and shoulder joint surgery, reducing the cutting effect at the suture site. A larger footprint surface also promotes wound healing. However, due to the shape of round / flat sutures, the flat segment is more prone to knotting and tangling, increasing the difficulty of suture management and significantly impacting surgical efficiency, while also failing to fully utilize the advantage of a large footprint surface. Currently, for the treatment of round / flat sutures, doctors will manually use a probe to remove them (e.g., Figure 1 As shown in the image, the main method involves using a hook to grasp the flat suture and then slowly straightening it. This method results in a long surgical time and low efficiency. Currently, there are no specialized tools for straightening round / flat sutures.

[0003] Therefore, it is of great significance to develop a dedicated tool and method for quickly, efficiently, and conveniently organizing round / flat lines. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to provide a suture management tool and method for surgical flat / round flat sutures.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A suture management tool for surgical sutures, wherein the surgical suture is a flat suture or a round flat suture, and mainly consists of a suture plate and a handle connected to the suture plate;

[0007] The pressure plate is a long strip structure. One side of the long strip structure is a surface that can fit with a footprint surface of the suture, referred to as the fitting surface. An inlet groove for the surgical suture to pass through is provided on the fitting surface.

[0008] The handle is provided with a flat groove for the surgical suture to pass through. The flat groove is a strip-shaped groove, and the groove direction is consistent with the length direction of the pressure plate.

[0009] The sidewalls of both the inlet groove and the flat groove are in contact with the two footprint surfaces of the surgical suture. The distance between the two sides of the inlet groove and the flat groove that are in contact with the surgical suture is matched with the thickness of the surgical suture to keep the surgical suture sliding in the groove without curling.

[0010] The inlet groove corrects the flat wire segment, preventing it from curling or knotting after entering. The thickness of an unorganized flat wire segment is increased compared to its organized state. Based on the previously mentioned matching of the groove height with the wire segment thickness, only properly organized segments can enter. Inside the groove, the shape of the flat wire is essentially "fixed" (thickness limits deformation), and the wire's head is hardened, ensuring easy penetration into the groove without deformation.

[0011] The round end of the flat suture is round, and this tool can also be used for styling. Simply pass the round suture segment through the handle. In actual surgery, the round end is only used for passing the suture; it is not actually used for suturing (otherwise, the advantages of the flat suture would not be realized). Because the round end is not used for suturing, you can directly cut off the round end and use this suture styling tool, or skip the round end and insert the flat suture segment into the suture styling tool through the side opening.

[0012] As a preferred technical solution:

[0013] As described above, the surgical suture management tool has a side-opening groove and a flat groove, allowing the suture to be inserted or removed from the side (if uncontrollable factors result in poor suture management, the suture can be directly removed from the side for replacement or re-management); the side refers to the side perpendicular to the thickness direction of the surgical suture. To further facilitate suture passage, the groove is designed with a one-sided opening, allowing the suture to be inserted or removed from the opening. If the suture bundle cannot be successfully shaped during management, it can be directly removed from the side opening; similarly, for round or flat sutures, they can be directly inserted from the side opening.

[0014] As described above, a surgical suture management tool has a flat groove located inside the handle and integrally formed with the handle; the connection between the pressure plate and the handle is the inlet of the flat groove, and the other end of the handle (i.e., the end opposite to the connection) is the outlet of the flat groove. The side of the flat groove that is in contact with the surgical suture is coplanar with the contact surface of the pressure plate, and the other side of the flat groove that is in contact with the surgical suture and the inlet groove are located on the same side of the contact surface.

[0015] As described above, a surgical suture management tool has an inlet groove that is U-shaped. The U-shaped groove has a U-shaped cross-section, but the opposite sides of the U-shape are parallel to each other and are straight or curved. One of the opposite sides of the U-shaped groove is coplanar with the bonding surface (the position on the bonding surface where the inlet groove is not provided can be a plane or a curved surface, as long as it can fit with one footprint surface of the suture).

[0016] The number of inlet slots is n, where n≥2; the inlet slot closest to the flat slot is denoted as the nth inlet slot, and the farthest inlet slot is denoted as the first inlet slot; the surgical suture can be inserted into the inlet slots in a straight line without flipping, according to the inlet slot number. The cross-section of the inlet slot can be, but is not limited to, rectangular or curved (such as a combination of arc, arch, etc.) shapes.

[0017] As described above, a surgical suture management tool features an angled structure at the entrance of each inlet groove and the entrance of the flat groove. This angled structure refers to the inclination at the entrance of each inlet groove and the flat groove along the direction of the surgical suture entry (i.e., along the thickness direction of the surgical suture, the side that is in contact with the surgical suture is tilted away from the surgical suture), increasing the distance between the two sides of the inlet groove and the flat groove that are in contact with the surgical suture. The angle of inclination decreases as the inlet groove number increases, until the angle of inclination of the flat groove is 0-5°. Different groove entrance angles (inlet angles) are designed for different suture entry positions to facilitate the pre-loading of the surgical suture into the management tool. The handle end of the management tool has a suture guide groove. For example, if the first inlet groove has a 75° angle, the flat suture can easily pass through the management tool. The second angle is set to 60°, the third angle to 45°, the fourth angle to 30°, and so on, until the angle at the suture guide groove opening is set within 0-5°, ensuring that the suture entering the suture guide groove is properly managed.

[0018] As described above, in a surgical suture management tool, after passing through the beveled structure of the flat groove, the ratio of the distance between the two sides of the flat groove that fit with the surgical suture to the thickness of the surgical suture strip is 1:1 to 1.3. This allows the flat suture segment to easily enter the groove without deforming within it.

[0019] As described above, a surgical suture management tool has a suture groove inside the handle, which has the same structure as the flat groove and is located on the same horizontal plane. The connection between the pressure plate and the handle is the entrance to the suture groove. A single or double roller is located between the suture groove and the flat groove to compress the surgical suture. The single or double roller is fixed to the handle by a roller pin (i.e., a pin secures the roller to the handle). The cross-section after the suture groove entrance is rectangular or curved (such as a combination of arc and arch shapes). The single roller achieves compression by engaging with the flat groove, while the double roller achieves compression through the meshing of the upper and lower rollers. Compression refers to keeping the surgical suture taut. The resilient material of the roller tightly presses the surgical suture. During surgery, the surgeon can pull the other end to keep the entire surgical suture taut. This tautness allows for better suture shaping (a taut surgical suture is less prone to deformation), and the single or double roller controls the length during suture passage, improving suture passage efficiency. After the rollers press the wires together, pushing the rollers will enable the wire feeding and output functions.

[0020] As described above, a surgical suture management tool has a single or double roller wrapped with a tough material (such as rubber, which facilitates pressing the suture tightly); the surface of the tough material that contacts the surgical suture has protrusions (which can improve the efficiency of suture passage and prevent slippage).

[0021] As described above, the length of the suture channel for a surgical suture is 100mm to 200mm, depending on the length required for the surgery.

[0022] The present invention also provides a method for arranging surgical sutures using a suture arranging tool as described in any of the preceding claims, wherein one footprint surface of the surgical suture is attached to the bonding surface of the suture plate and sequentially inserted into the inlet groove, then inserted into the flat groove along the bonding surface of the suture plate and exited from the flat groove, thereby completing the arrangement of the surgical suture.

[0023] The mechanism of this invention is as follows:

[0024] Because flat sutures that are not taut are prone to deformation, in actual use, such as when passing through soft tissue, the sides of the suture will deform, and once deformed, it is not easy to restore its original shape. A suture management tool can be used to straighten the flat suture at this time. The doctor holds the suture at the other end and then pushes the roller to cover the area that needs to be sutured with the suture that has been straightened in the flat groove.

[0025] This invention utilizes an inlet groove, a thread guide groove, and a flat opening groove to shape and conform the round / flat thread bundle to the thread-bundling plane of the suture management tool (serving as a limit and maintaining the suture's tautness to a certain extent). The inlet groove at the front of the suture management tool's handle continuously corrects the flat thread's shape, and the thread guide groove at the handle's end has a height matching the thickness of the flat thread, ensuring that the flat thread does not curl or knot after entering the flat opening groove. The roller design ensures smooth thread passage and maintains the flat thread's well-organized state during the process. In actual operation, the doctor operates the roller to deliver the thread while simultaneously pulling the round / flat thread on the opposite side, thus covering the area requiring suturing with the well-organized flat thread segment.

[0026] Beneficial effects

[0027] (1) A surgical suture management tool of the present invention is suitable for managing flat / round flat sutures, and is easy to operate and has high suture management efficiency;

[0028] (2) A surgical suture management tool of the present invention restricts the round and flat suture segments to fit the handle plane through the inlet groove, and the toothed roller design better presses the round and flat sutures to control the shape and the suture entry and exit operation, so that the sorted round and flat sutures fit into the inner groove of the handle;

[0029] (3) The surgical suture management tool of the present invention greatly improves the suture management effect by designing the oblique angle of each groove, the cross-sectional shape of the inlet groove and the roller pressing the suture.

[0030] (4) The present invention provides a method for organizing surgical sutures, which makes it easy to organize the round and flat sutures during the operation, so that the footprint surface can better fit the suture site and ensure that the round and flat sutures of the suture section do not curl or knot; the doctor only needs to pull the suture on the opposite side to fit the organized round and flat sutures into the surgical suture area.

[0031] (5) This invention can better leverage the advantages of round / flat sutures in clinical applications, ensuring that the flat suture segment's footprint adheres to the human tissue after entering the body during surgical suturing, the flat suture segment does not curl, and there are no knotted areas within the suture segment, thus reducing the cutting effect of the surgical suture on the human tissue.
