Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, and in particular relates to a novel suture-removing tweezers. Background Art
[0002] Suture removers are a tool specifically used to remove sutures and are widely used in the medical and cosmetic fields. Suture removers usually have slender jaws with hooked or pointed ends to facilitate grasping sutures. They are generally made of stainless steel to ensure durability and corrosion resistance and are easy to disinfect and clean. When in use, the doctor or caregiver will insert the hooked end of the tweezers into the loop of the suture and then gently pull out the wire.
[0003] At present, most of the existing suture removal forceps are not provided with a suture incision. During the suture removal process, the doctor may need to use a suture removal scissors together. The operation process is cumbersome and inconvenient for rapid suture removal, which reduces the practicality of the device to a certain extent. In addition, most of the existing suture removal forceps are not provided with a limit structure. When the doctor uses the instrument, the suture removal forceps may become unstable, which is not conducive to safe suture removal and affects the reliability of the device to a certain extent. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a new type of suture-removing tweezers to solve the problems existing in the above-mentioned background technology.
[0005] The utility model provides the following technical solution: a new type of suture-removing tweezers, comprising:
[0006] Suture-removing tweezers, the suture-removing tweezers comprising a tweezers handle;
[0007] The limiting mechanism includes two groups of insertion holes, and the two groups of insertion holes are respectively opened inside the outer surfaces of both sides of the tweezers handle.
[0008] Preferably, the stitch-removing tweezers further include anti-slip grooves, and the anti-slip grooves are arranged on the outer surfaces of both sides of the tweezers handle, and the outer surface of one end of the tweezers handle is fixedly connected to a first clamping foot. The anti-slip grooves can prevent the stitch-removing tweezers from slipping when held in hand.
[0009] Preferably, a tangent port is provided on the outer surface of one side of the first clamping foot, and a second clamping foot is fixedly connected to the outer surface of the other end of the tweezers handle, and the suture can be cut through the tangent port, thereby better removing the suture.
[0010] Preferably, the size of the first clamping foot is the same as that of the second clamping foot, and the outer surfaces of the opposite sides of the first clamping foot and the second clamping foot are provided with concave and convex patterns. By providing the concave and convex patterns, the friction between the first clamping foot and the second clamping foot and the suture thread can be increased to prevent loose clamping.
[0011] Preferably, the limiting mechanism also includes a threaded rod, and the outer surface of one end of the threaded rod is inserted into the interior of the insertion hole, and a limiting ring is provided on the outer surface of the other end of the threaded rod. The limiting ring on the threaded rod can prevent the threaded rod from escaping from the interior of the insertion hole.
[0012] Preferably, the middle part of the outer surface of the threaded rod is threadedly connected to a first limiting wheel, and one end of the outer surface of the threaded rod is threadedly connected to a second limiting wheel, and the size of the first limiting wheel is the same as the size of the second limiting wheel. The tweezers handle is limited by the first limiting wheel and the second limiting wheel, and the tweezers handle can always be in a clamped state.
[0013] The technical effects and advantages of this utility model are:
[0014] 1. The utility model is provided with suture-removing tweezers. During the suture removal process, the doctor only needs to use the incision to cut the suture, and then use the first clamping foot and the second clamping foot to clamp it. The doctor does not need to use the suture-removing scissors to operate together. The operation process is relatively simple, which is convenient for quick suture removal and improves the practicality of the device to a certain extent.
[0015] 2. The utility model is provided with a limiting mechanism. When the doctor uses the instrument, he first rotates and adjusts the first limiting wheel and the second limiting wheel to the appropriate position. In the process of pinching the tweezers handle, the first limiting wheel and the second limiting wheel limit the position of the tweezers handle, avoiding the situation where the suture removal tweezers are unstable, which is conducive to safe suture removal and improves the reliability of the equipment to a certain extent.

DETAILED DESCRIPTION
[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The new type of suture-removing tweezers involved in the present invention are not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work fall within the scope of protection of the present invention.
[0024] Example 1
[0025] like Figures 1 to 4 As shown, the utility model proposes a novel stitch-removing tweezers, comprising stitch-removing tweezers 1, which comprise a tweezers handle 11. The stitch-removing tweezers 1 further comprise anti-slip grooves 12, and the anti-slip grooves 12 are arranged on the outer surfaces of both sides of the tweezers handle 11, and the outer surface of one end of the tweezers handle 11 is fixedly connected to a first clamping foot 13, and the stitch-removing tweezers 1 are made of stainless steel. Stainless steel is an alloy steel mainly composed of iron, carbon and chromium. It is widely used in many fields due to its excellent corrosion resistance, strength and aesthetics. The presence of chromium forms a protective oxide film to prevent oxidation and corrosion. The surface is smooth and not easy to adhere to dirt. It is suitable for environments with high hygienic requirements. Due to its corrosion resistance and easy cleaning, it is often used in surgical instruments and medical equipment. Holding the anti-slip grooves 12 for operation can avoid the situation where the outer surface of the tweezers handle 11 is slippery.
[0026] A tangent port 14 is provided on the outer surface of one side of the first clamping foot 13, and a second clamping foot 15 is fixedly connected to the outer surface of the other end of the tweezers handle 11. The size of the first clamping foot 13 is the same as that of the second clamping foot 15, and concave-convex patterns 16 are provided on the outer surfaces of the opposite sides of the first clamping foot 13 and the second clamping foot 15. The suture thread can be cut through the tangent port 14 and then removed through the first clamping foot 13 and the second clamping foot 15. The concave-convex patterns 16 can increase the friction between the suture thread and the suture thread to prevent instability during suture removal.
[0027] Example 2
[0028] like Figure 5 and Figure 6 As shown, this embodiment also proposes:
[0029] The limiting mechanism 2 includes two groups of insertion holes 21, and the two groups of insertion holes 21 are respectively opened inside the outer surfaces of both sides of the tweezers handle 11. The size of the insertion holes 21 is larger than the size of the threaded portion of the threaded rod 22, and the threaded rod 22 will not block the movement of the tweezers handle 11;
[0030] The limiting mechanism 2 also includes a threaded rod 22, and the outer surface of one end of the threaded rod 22 is inserted into the insertion hole 21, and a limiting ring is provided on the outer surface of the other end of the threaded rod 22. The limiting ring on the threaded rod 22 can prevent the threaded rod 22 from being separated from the insertion hole 21. At the same time, during operation, the position of the tweezers handle 11 can be limited;
[0031] The middle part of the outer surface of the threaded rod 22 is threadedly connected to a first limiting wheel 23, and one end of the outer surface of the threaded rod 22 is threadedly connected to a second limiting wheel 24, and the size of the first limiting wheel 23 is the same as the size of the second limiting wheel 24. By rotating the first limiting wheel 23 and the second limiting wheel 24, the first limiting wheel 23 and the second limiting wheel 24 can be moved on the outer surface of the threaded rod 22, thereby limiting the pinching angle of the tweezers handle 11, and the second limiting wheel 24 can be rotated and adjusted to the deepest position to limit the tweezers handle 11 to the minimum position. At this time, the first clamping foot 13 and the second clamping foot 15 are in contact with each other, and the suture line can be continuously clamped.
[0032] Working principle: First, thoroughly disinfect the instrument, then cut the suture through the position of the incision port 14, then rotate and adjust the position of the first limiting wheel 23 and the second limiting wheel 24 to limit the angle of the tweezers handle 11, and finally, simply hold the position of the anti-slip groove 12 to remove the suture. The above is the entire working principle of the utility model.
[0033] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.
[0034] Secondly: The drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.
[0035] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
