Description

Technical Field

[0001] This utility model relates to the technical field of medical suture production equipment, and in particular to a suture-grabbing and cutting mechanism for medical suture production equipment. Background Technology

[0002] Barbed medical sutures have advantages such as eliminating the need for knotting and reducing tissue damage. Their production involves processes such as clamping, cutting, and barb processing.

[0003] Patent application number 202510570777.X discloses a clamping and rotating mechanism and a suture cutting mechanism. The clamping and rotating mechanism uses a third and fourth clamping plate with mutually perpendicular directions of movement to grip the suture and rotate it. The suture cutting mechanism is responsible for cutting the suture. The inventors believe that it has certain drawbacks: First, the clamping and rotating mechanism and the suture cutting mechanism are two independent sets of mechanisms, which not only increases the overall size of the equipment but also increases the manufacturing cost. Second, there is a certain distance between the clamping and rotating mechanism and the suture cutting mechanism, and the suture at this distance cannot be barbed and must be cut off, resulting in a longer section of suture being cut off and more material being wasted.

[0004] Therefore, it is necessary to develop a suture-grabbing and cutting mechanism for medical suture production equipment to address the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a centering gripping and cutting mechanism for medical suture production equipment, which aims to solve the defects of large equipment size, high manufacturing cost, and excessive waste of suture material caused by two independent mechanisms.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a suture production equipment with a suture-grabbing and cutting mechanism, comprising a connecting seat. The connecting seat has a through hole coaxially formed for the suture to pass through. A first clamping drive and a second clamping drive are fixed to one end of the connecting seat. A first clamping mechanism for clamping the suture is fixed to the output end of the first clamping drive, and a second clamping mechanism for clamping the suture is fixed to the output end of the second clamping drive. The movement directions of the first clamping mechanism and the second clamping mechanism are perpendicular to each other. The first clamping mechanism is inserted into the second clamping mechanism. A cutting mechanism for cutting the suture is provided on the side of the second clamping mechanism near the connecting seat.

[0007] Optionally, the first clamping mechanism includes a first clamp and a second clamp, and the second clamping mechanism includes a third clamp and a fourth clamp. One end of the first clamp is movably disposed between the third clamp and the fourth clamp, and one end of the second clamp movably passes through the third clamp and extends into the space between the third clamp and the fourth clamp.

[0008] Optionally, a first slot is provided on the opposite side of the third gripper and the fourth gripper, and one end of the first gripper is inserted into the space between the two first slots; a second slot is provided on the side of the third gripper away from the fourth gripper, the second slot is connected to the first slot on the third gripper, one end of the second gripper passes through the second slot and extends into the space between the two first slots, and both ends of the second slot in the length direction are spaced apart from the second gripper.

[0009] Optionally, the cutting mechanism includes a blade, which is fixedly connected to the fourth or third gripper, and the third or fourth gripper has a groove for cooperating with the blade.

[0010] Optionally, both the first and second clamping drive components are finger cylinders, and the finger cylinders are fixedly connected to the connecting seat; one slider of the first clamping drive component is fixedly connected to the first gripper, the other slider of the first clamping drive component is fixedly connected to the second gripper, one slider of the second clamping drive component is fixedly connected to the third gripper, and the other slider of the second clamping drive component is fixedly connected to the fourth gripper.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention integrates the functions of gripping and cutting sutures into one mechanism, replacing two separate mechanisms. This significantly reduces the size of the equipment, and the cutting mechanism is simple in structure and easy to manufacture, greatly reducing equipment costs.

[0012] The cutting mechanism is integrated into the second clamping mechanism, which greatly shortens the area where the suture cannot be processed for barbs, reduces waste, and improves material utilization. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In a specific embodiment of this utility model, a connecting seat 100 (i.e., the second connecting seat in patent application number 202510570777.X) is included. A through hole 101 for the passage of sutures is coaxially provided on the connecting seat 100. A first clamping drive member 200 and a second clamping drive member 300 are fixed to one end of the connecting seat 100. A first clamping mechanism for clamping sutures is fixed on the output end (i.e., slider) of the first clamping drive member 200 (i.e., the two sliders of the first clamping drive member 200 are respectively connected to the two jaws of the first clamping mechanism, driving them to open and close). A second clamping mechanism for clamping sutures is fixed on the output end (i.e., slider) of the second clamping drive member 300 (i.e., the two sliders of the second clamping drive member 300 are respectively connected to the two jaws of the second clamping mechanism, driving them to open and close). The movement directions of the first clamping mechanism and the second clamping mechanism are perpendicular to each other. The first clamping mechanism is inserted into the second clamping mechanism. A cutting mechanism for cutting sutures is provided on the side of the second clamping mechanism near the connecting seat 100.

[0021] In a specific embodiment of this utility model, the first clamping mechanism includes a first clamping jaw 400 and a second clamping jaw 500, and the second clamping mechanism includes a third clamping jaw 600 and a fourth clamping jaw 700. One end of the first clamping jaw 400 is movably disposed between the third clamping jaw 600 and the fourth clamping jaw 700, and one end of the second clamping jaw 500 movably passes through the third clamping jaw 600 and extends into the space between the third clamping jaw 600 and the fourth clamping jaw 700.

[0022] In a specific embodiment of this utility model, a first slot 800 is provided on the opposite side of the third gripper 600 and the fourth gripper 700. One end of the first gripper 400 is inserted into the space between the two first slots 800 (hereinafter referred to as the clamping space). A second slot 900 is provided on the side of the third gripper 600 away from the fourth gripper 700. The second slot 900 communicates with the first slot 800 on the third gripper 600. One end of the second gripper 500 passes through the second slot 900 and extends into the space between the two first slots 800 (i.e., the clamping space). Both ends of the second slot 900 in the length direction are spaced apart from the second gripper 500, so that the third gripper 600 will not affect the movement of the second gripper 500 towards or away from the first gripper 400. When the first gripper 400 and the second gripper 500 are in contact with each other at one end within the clamping space, the central axis of the through hole 101 passes through the contact surface; when the third gripper 600 and the fourth gripper 700 are in contact with each other, the central axis of the through hole 101 passes through the contact surface; the central axis of the through hole 101 passes through the contact surface of the first clamping mechanism and the second clamping mechanism, which can ensure that the suture is coaxial with the through hole 101 when it is clamped, thus realizing "center gripping".

[0023] In a specific embodiment of this utility model, the cutting mechanism includes a blade 1000, which is fixedly connected to a fourth gripper 700 or a third gripper 600. Specifically, the fourth gripper 700 or the third gripper 600 has a mounting groove for accommodating the blade 1000 on the side near the connecting seat 100. The blade 1000 is fixedly connected to the mounting groove by screws. The third gripper 600 or the fourth gripper 700 has a cutting groove 1100 for cooperating with the blade 1000.

[0024] In a specific embodiment of this utility model, both the first clamping drive member 200 and the second clamping drive member 300 are finger cylinders, and the finger cylinders are fixedly connected to the connecting seat 100 by screws; one slider of the first clamping drive member 200 is fixedly connected to the first gripper 400 by screws, the other slider of the first clamping drive member 200 is fixedly connected to the second gripper 500 by screws, one slider of the second clamping drive member 300 is fixedly connected to the third gripper 600 by screws, and the other slider of the second clamping drive member 300 is fixedly connected to the fourth gripper 700 by screws.

[0025] The working principle of the suture-grabbing and cutting mechanism of this utility model medical suture production equipment is as follows: The first clamping drive 200 drives the first clamp 400 and the second clamp 500 to approach each other and clamp the suture. At the same time, the second clamping drive 300 drives the third clamp 600 and the fourth clamp 700 to approach each other and clamp the suture. When the third clamp 600 and the fourth clamp 700 clamp the suture, the blade 1000 cooperates with the blade groove 1100 to cut the suture.

[0026] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
