Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a ring scissors. Background Technology

[0002] Traditional suture scissors are typically handheld, resembling small scissors or suture cutters. Existing improvement plans generally focus on refining the design of existing scissors, such as making them more ergonomic. However, in actual clinical practice, when there is no dedicated person to perform the suture cutting, a medical staff member must operate the suture alone. This requires finding the suture scissors on the instrument table, cutting the suture, and then returning it to the instrument table. When multiple cutting operations are required, this necessitates repeatedly picking up and putting down the suture scissors. Especially when there are many instruments, it also requires searching among numerous instruments or necessitates the assistance of an assistant or scrub nurse, which is quite time-consuming.

[0003] In other fields, such as emergency rescue equipment, there are forms of scissors that are hidden in rings. However, due to safety concerns, this type of ring scissors cannot be used in the medical field. Utility Model Content

[0004] The purpose of this utility model is to provide a ring scissors that solves the technical problem in the prior art where the scissors need to be repeatedly picked up and put down when cutting the sewing thread, which wastes time.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides a ring scissors, comprising:

[0006] It includes a ring, a safety box, and a scissor assembly. The ring is fixedly connected to the safety box, and the scissor assembly is installed inside the safety box to prevent the scissor assembly from damaging human tissue.

[0007] The safety box has a thread-cutting slot on the side away from the ring, which communicates with the internal space of the box. The thread-cutting slot is used to position the suture to be cut.

[0008] The thread-cutting groove extends toward the ring and overlaps with the cutting range of the scissors assembly, so that the scissors assembly, which is entirely within the safety box, can cut the suture located within the thread-cutting groove.

[0009] In a preferred embodiment of this utility model, the wire cutting groove is configured as a V-shaped groove.

[0010] As a preferred embodiment of this utility model, the safety box is made of transparent plastic to allow observation of the relative positions of the scissors and the sewing thread.

[0011] In a preferred embodiment of this utility model, the extension direction of the wire-cutting groove is perpendicular to the wearing direction of the ring.

[0012] In a preferred embodiment of this utility model, the scissor assembly includes pressing blocks arranged sequentially along the extending direction of the cutting groove, two transmission rods, and scissors; wherein...

[0013] The scissors are installed directly below the thread cutting groove. When the blades of the scissors are open, they are located on both sides of the thread cutting groove. When the blades are closed, they can cut the suture thread.

[0014] The two ends of the transmission rod are connected to the pressing block and the handle of the scissors respectively through universal joints, and the distance between the two connection points on the pressing block is greater than the distance between the two connection points on the scissors. The two transmission rods are arranged in a figure-eight shape.

[0015] The pressing block is slidably connected to one side wall of the safety box, and an elastic telescopic rod is provided between the pressing block and the opposite side wall.

[0016] In a preferred embodiment of this utility model, the distances of the scissors from the two ends of the wire cutting groove are 10mm and 2mm, respectively.

[0017] As a preferred embodiment of this utility model, the ring is an open ring with an adjustable diameter to improve its applicability.

[0018] As a preferred embodiment of this utility model, the safety box has an installation position on its outer side for installing a distance block for measuring the length of the reserved suture line. The distance block has a suture cutting groove with the same cross-section as the safety box.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] This invention integrates a scissor assembly into a ring. When worn by a doctor, this ring-shaped scissor avoids the time-consuming process of repeatedly picking up and putting down the suture. Since the scissors are always worn on the finger, they are quick and convenient to raise, and allow for more accurate self-operation. Furthermore, the scissor assembly is housed in a sealed safety box with only a single suture-cutting slot, effectively preventing accidental injury to human tissue. The suture-cutting slot extends towards the ring, overlapping with the cutting range of the scissors assembly. This design, while ensuring safety, allows the scissors assembly to cut the suture within the suture-cutting slot. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model specifically provides a ring scissors, such as Figures 1 to 5 As shown, it includes:

[0031] It includes a ring 1, a safety box 2, and a scissor assembly. The ring 1 is fixedly connected to the safety box 2, and the scissor assembly is installed inside the safety box 2 to prevent the scissor assembly from damaging human tissue.

[0032] The safety box 2 is provided with a thread cutting slot 3 on the side away from the ring 1, which communicates with the internal space of the box. The thread cutting slot 3 is used to position the suture to be cut.

[0033] The thread-cutting groove 3 extends toward the ring 1 and overlaps with the cutting range of the scissors assembly, so that the scissors assembly, which is completely located inside the safety box 2, can cut the suture located in the thread-cutting groove 3.

[0034] When using, wear the ring 1 on your finger, put the suture to be cut into the suture cutting slot 3 so that the suture is within the cutting range of the scissor assembly, and then use the scissor assembly to cut the suture.

[0035] Understandably, the scissor assembly can be electrically driven, for example, by touching the start button with a finger, which causes the scissors 6 to perform a cutting action; or it can be manually driven, for example, by pressing the button with the thumb, which drives the scissors 6 to perform a cutting action through the transmission component.

[0036] In summary, this invention, by installing the scissor assembly within a ring, allows doctors to avoid repeatedly picking up and putting down the suture cutter, which is time-consuming. The ring scissors are always worn on the finger, making it quick and convenient to raise the hand, greatly improving suture cutting efficiency. Simultaneously, the scissor assembly is installed in a safety box 2, which is enclosed on all sides with only a suture cutting slot 3, effectively preventing the scissor assembly from injuring human tissue. The suture cutting slot 3 extends towards the ring 1, overlapping with the cutting range of the scissor assembly, ensuring both safety and allowing the scissor assembly to cut the suture within the suture cutting slot 3.

[0037] Furthermore, the suture cutting groove 3 is designed as a V-shaped groove, wider at the top and narrower at the bottom. The wider opening facilitates the entry of the suture into the suture cutting groove 3; the narrower bottom facilitates the positioning of the suture.

[0038] Furthermore, the safety box 2 is made of transparent plastic so that the relative position of the scissors 6 and the suture line can be observed, thereby confirming the reserved length after the suture line is cut.

[0039] Furthermore, the extension direction of the suture cutting groove 3 is perpendicular to the wearing direction of the ring 1. At this time, the finger joint will not obstruct the safety box 2 from approaching the human tissue, which is more ergonomic and can better control the reserved length after the suture is cut.

[0040] Furthermore, the scissor assembly includes pressing blocks 4, two transmission rods 5, and scissors 6 arranged sequentially along the extending direction of the cutting groove 3; wherein,

[0041] The scissors 6 are installed directly below the thread cutting groove 3. When the blades of the scissors 6 are open, they are located on both sides of the thread cutting groove 3. When the blades are closed, they can cut the sewing thread.

[0042] The two ends of the transmission rod 5 are connected to the pressing block 4 and the handle of the scissors 6 respectively through universal joints, and the distance between the two connection points on the pressing block 4 is greater than the distance between the two connection points on the scissors 6. The two transmission rods 5 are arranged in a figure-eight shape.

[0043] The pressing block 4 is slidably connected to one side wall of the safety box 2, and an elastic telescopic rod 7 is provided between the pressing block 4 and the opposite side wall.

[0044] The method for using the above-mentioned clipping component is as follows:

[0045] After the suture enters the suture groove 3, the thumb presses down on the pressing block 4, which moves into the safety box 2 against the elastic force of the telescopic rod 7. Since the pressing block 4 is connected to the two handles of the scissors 6 by two transmission rods 5 arranged in a figure-eight shape, as the pressing block 4 moves into the safety box 2, the transmission rods 5 drive the handles of the scissors 6 to move closer together, thereby closing the blades of the scissors 6 and completing the cutting action.

[0046] After the suture is cut, the thumb releases the pressing block 4, the elastic telescopic rod 7 returns to its original position and extends, driving the pressing block 4 to reset, and the scissors 6 reopen.

[0047] The aforementioned universal joint is existing technology, and its specific structure can be as follows: each universal joint includes two mutually perpendicular rotating columns, one of which passes through the other rotating shaft; the universal joint located on one side of the scissors 6 has its two rotating columns rotatably connected to the handle of the scissors 6 and the transmission rod 5 respectively; the universal joint located on one side of the pressing block 4 has its two rotating columns rotatably connected to the pressing block 4 and the transmission rod 5 respectively.

[0048] Furthermore, for external skin sutures, a 10mm suture length is generally reserved, while for internal organ sutures, a 2mm cutting suture length is generally reserved. An installation position 8 can be set on the outside of the safety box, and this installation position 8 can be configured as a bayonet. Then, two distance blocks 9 of different lengths are prepared: one external and one internal. Each distance block has a cutting groove 3 identical to that of the safety box 2. If the suture is cut internally, it is installed into the internal distance block in the groove, so that the distance from the suture end to the scissors 6 is 2mm; if the suture is cut externally, it is installed into the external distance block in the groove, so that the distance from the suture end to the scissors 6 is 10mm.

[0049] Understandably, the distance between the scissors 6 and the outer wall of the safety box can also be set to 2mm. When cutting the wire inside the body, there is no need to install a distance block. Only one external distance block needs to be set, which is then installed on the slot when cutting the wire outside the body.

[0050] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
