Description

Technical Field

[0001] This invention relates to the field of operating room nursing aids technology, specifically to a circular surgical suture collection and counting device. Background Technology

[0002] Surgical sutures are needle-shaped instruments used in surgical procedures to suture tissue. They consist of three parts: the needle tip, the needle body, and the needle tail. The needle body is curved or straight with a smooth surface to reduce tissue damage during puncture. The needle tail is used to attach the suture. The surgeon holds the needle tail with a needle holder, passes the needle and suture through the tissue, and then ties a knot to close the wound or align the tissue. It is one of the most basic and frequently used surgical tools.

[0003] Current methods for recovering surgical sutures mostly rely on sharps boxes, magnetic needle plates, or manual counting. Sharps boxes are typically used for centralized disposal after surgery. When temporarily recovering sutures during surgery, it is difficult to individually retrieve and verify them after they have been placed in the box. Counting the number requires emptying the box or using tools, which is not only unintuitive but also increases the risk of secondary contamination and needlestick injuries. Magnetic devices can attract ferromagnetic sutures, but they are difficult to effectively fix non-magnetic materials such as titanium alloys and polymers. Moreover, the attraction force varies greatly between different sizes of sutures, making them easy to slip off due to vibration or contact. In addition, after magnetic attraction, each suture still needs to be counted manually, making it difficult to directly display the usage status. Ordinary counting pads or needle boxes are bulky and require unfolding, opening the lid, or finding the corresponding slot, making the operation cumbersome. During the busy surgical process, medical staff often do not have time to classify and place the sutures, resulting in haphazard placement, making postoperative counting difficult and prone to omissions. Summary of the Invention

[0004] The purpose of this invention is to provide a circular surgical suture needle retrieval and counting device to solve the problems of inconvenient surgical suture needle retrieval methods, unintuitive counting, and the risk of needle pricks in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circular surgical suture needle recycling and counting device, comprising a circular body, a pressing guide area provided on the upper surface of the circular body, an elastic insertable fixing layer and a bottom layer provided inside the circular body, the bottom layer being disposed below the elastic insertable fixing layer, and a color-indicating component also provided inside the circular body;

[0006] The color-indicating component includes a driving member and a rotating cylinder rotatably connected to the bottom layer. A connecting rod is fixedly connected to the outside of the rotating cylinder, and an arc-shaped color plate is fixedly connected to the end of the connecting rod away from the rotating cylinder. An arc-shaped sleeve is fixedly connected to the inside of the circular body, and the arc-shaped color plate can be inserted into the arc-shaped sleeve. The driving member is located below the elastic piercing fixing layer, and the driving member abuts against a suture needle that penetrates the elastic piercing fixing layer.

[0007] Furthermore, the pressing guide area is a cross-shaped groove, and the diameter of the cross-shaped groove is larger than the diameter of the needle.

[0008] Furthermore, a numbered identification area is provided on the outside of the main body of the circular piece.

[0009] Furthermore, the driving component includes a lower pressure plate, a protrusion is fixedly connected to the side of the lower pressure plate, a spiral groove is provided on the rotating cylinder, and the protrusion is slidably connected in the spiral groove.

[0010] Furthermore, the driving component also includes a first elastic element, which is disposed inside the rotating drum, and both ends of the first elastic element are respectively connected to the lower pressure plate and the bottom layer.

[0011] Furthermore, it also includes a snap-fit ​​assembly that detachably connects the plurality of the circular bodies.

[0012] Furthermore, the buckle assembly includes a connecting seat and an insert block fixedly connected to the outside of the circular piece body. The connecting seat and the insert block are respectively disposed on both sides of the circular piece body. The connecting seat has two symmetrically opened slots, and the insert block has a receiving cavity. The two ends of the receiving cavity are symmetrically slidably connected to the locking blocks. The receiving cavity is provided with a second elastic member, and the two ends of the second elastic member are respectively connected to the two locking blocks.

[0013] Furthermore, the two locking blocks are engaged into the two locking slots under the thrust of the second elastic element.

[0014] Compared with existing technologies, the circular surgical suture collection and counting device provided by this invention automatically clamps the suture by inserting it into the pressure guide area and the elastic fixation layer, eliminating the need to open the box lid or find the slot. It is extremely convenient to operate with one hand. Through the downward rotation structure in the color indicator component, pressing down on the suture tip pushes the arc-shaped color plate out. After releasing, the color plate remains in the slid-out state, clearly showing the usage status. The status can be checked by scanning after surgery or during surgery, effectively solving the problem of the sharps box not being intuitive to count. The device is applicable to both metal and non-magnetic sutures, and the elastic fixation layer can adapt to different sizes of sutures, avoiding the material limitations of magnetic plates. Each circular piece has an independent number and can be connected into a group through the buckle component. Nurses can quickly count the number of sutures according to the number of the used circular pieces and the status of the color plate without having to pull them out one by one. The overall structure is small and compact, and it is low-cost and easy to use as a disposable sterile consumable. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] Example 1:

[0028] This invention provides a circular surgical suture needle recycling and counting device, comprising a circular body 1, a pressing guide area 2 on the upper surface of the circular body 1, an elastic insertable fixing layer 3 and a bottom layer 4 inside the circular body 1, the bottom layer 4 being located below the elastic insertable fixing layer 3, and a color-indicating component 6 inside the circular body 1. The circular body 1 serves as the outer shell and support structure of the entire device, is circular in shape, and is semi-transparent, allowing color to pass through. Its hollow interior accommodates the elastic insertable fixing layer 3, the bottom layer 4, the color-indicating component 6, and other components. It can be held with one hand, facilitating quick retrieval and pressing by surgical personnel during surgery. The circular body 1 is made of medical-grade hard plastic, possessing a certain compressive strength to protect the internal components from external pressure damage. It also serves as a carrier for disposable consumables. The pressing guide area 2 is specifically a cross-shaped groove structure, with the diameter of the groove larger than the diameter of the surgical suture needle. Its function is to guide the needle tip of the used suture needle accurately into the circular body 1, preventing the needle tip from slipping on the surface of the circular body. Or deviate from the direction, while the recessed structure of the cross groove can also help the operator quickly locate the pressing point visually and tactilely. The elastic insertable fixing layer 3 is set inside the circular body 1, located directly below the pressing guide area 2. It is made of elastic polymer materials with self-healing properties such as medical silicone, medical rubber or elastic foam. When the suture needle is pressed and inserted, the elastic material undergoes elastic deformation due to compression, and then relies on its own recoil force to tightly wrap and hold the suture needle body, firmly fixing the suture needle inside the circular body 1 to prevent the suture needle from slipping or accidentally coming out. At the same time, the self-healing properties of the material can maintain a good clamping effect even after multiple punctures. The bottom layer 4 is set below the elastic insertable fixing layer 3. The bottom layer 4 plays the role of sealing the bottom of the circular body 1, and at the same time serves as the rotating connection base of the rotating cylinder 61 in the color-indicating component 6. The bottom layer 4 can be made of medical hard plastic or metal sheet to ensure that it will not deform too much during the pressing of the suture needle. The color-indicating component 6 is used to visualize the usage status of the circular piece.

[0029] The color-indicating component 6 includes a driving member 65 and a rotating cylinder 61 rotatably connected to the bottom layer 4. A connecting rod 62 is fixedly connected to the outside of the rotating cylinder 61, and an arc-shaped color plate 63 is fixedly connected to the end of the connecting rod 62 away from the rotating cylinder 61. An arc-shaped sleeve 64 is fixedly connected to the inside of the circular body 1, and the arc-shaped color plate 63 can be inserted into the arc-shaped sleeve 64. The driving member 65 is located below the elastically pierceable fixing layer 3, and the driving member 65 abuts against the needle that penetrates the elastically pierceable fixing layer 3. The rotating cylinder 61 is cylindrical and rotatably connected to the bottom layer 4, and can rotate around itself. When the axis rotates, and the protrusion 652 in the driving component 65 slides along the spiral groove 653, the linear motion of the lower pressure plate 651 is converted into the rotational motion of the rotating drum 61, thereby driving the connecting rod 62 and the arc-shaped color plate 63 to rotate together. One end of the connecting rod 62 is fixed to the outer wall of the rotating drum 61, and the other end is fixedly connected to the arc-shaped color plate 63. The connecting rod 62 is used to transmit the rotational power of the rotating drum 61 and transmit the rotation angle of the rotating drum 61 to the arc-shaped color plate 63, so that the arc-shaped color plate 63 can make arc motion around the axis of the rotating drum 61, thereby realizing the sliding from the arc-shaped sleeve 64. The arc-shaped color plate 63 is a sheet-like component with a certain curvature, and its surface is usually coated with a striking color (such as red). The arc-shaped color plate 63 can be inserted into the arc-shaped sleeve 64 to serve as a cover or display indicator. In the initial state, the arc-shaped color plate 63 is completely hidden inside the arc-shaped sleeve 64 and cannot be seen from the side wall of the circular body 1. When the sewing needle is pressed down to trigger the drive, the arc-shaped color plate 63 slides out from the arc-shaped sleeve 64 and is visible through the circular body 1 to indicate that it has been used. The arc-shaped sleeve 64 is fixedly connected to the inside of the circular body 1. On the wall, its inner cavity shape matches the arc-shaped color plate 63, forming an arc-shaped cylinder. The arc-shaped sleeve 64 is used to store and protect the arc-shaped color plate 63, and at the same time provides guidance for the sliding out and retraction of the arc-shaped color plate 63, preventing the color plate from shifting or getting stuck during movement. The driving component 65 moves downward when the needle is pressed down, and drives the rotating cylinder 61 to rotate through the cooperation of the protrusion 652 on it and the spiral groove 653 of the rotating cylinder 61. After the needle is pulled out, the driving component 65 resets under the action of the first elastic element 654, the rotating cylinder 61 rotates in the opposite direction, and the arc-shaped color plate 63 retracts.

[0030] The outer surface of the circular disc body 1 is provided with a numbering identification area 5. The numbering identification area 5 is located on the outside of the circular disc body 1 and forms a unique number, letter or barcode through printing, laser marking or mold engraving. Surgical nurses can quickly check the number of sutures according to the number sequence of the used discs without having to pull out each suture for inspection, thereby improving the efficiency and accuracy of counting and reducing the risk of sutures being left in the body.

[0031] The driving component 65 includes a lower pressure plate 651, with a protrusion 652 fixedly connected to the side of the lower pressure plate 651. A spiral groove 653 is provided on the rotating cylinder 61, and the protrusion 652 is slidably connected in the spiral groove 653. The lower pressure plate 651 is flat and is located below the elastic piercing fixing layer 3. When the needle pierces the elastic fixing layer, the needle tip will press against the upper surface of the lower pressure plate 651. When pressing down, the lower pressure plate 651 moves downward with the needle. The protrusion 652 is slidably connected in the spiral groove 653 on the rotating cylinder 61. When the protrusion 652 moves downward with the lower pressure plate 651, the protrusion 652 slides in the spiral groove 653. Since the spiral groove 653 has a spiral angle, the linear movement of the protrusion 652 forces the rotating cylinder 61 to rotate.

[0032] The driving component 65 also includes a first elastic element 654, which is disposed inside the rotating cylinder 61. The two ends of the first elastic element 654 are connected to the lower pressure plate 651 and the bottom layer 4, respectively. The first elastic element 654 can be a compression spring, which is compressed and stores energy when the needle is pressed down. When the needle is pulled out, the first elastic element 654 releases its elastic force, pushes the lower pressure plate 651 to reset upward, thereby causing the protrusion 652 to slide in the opposite direction, causing the rotating cylinder 61 to rotate in the opposite direction, and the arc-shaped color plate 63 to retract into the arc-shaped sleeve 64. The thrust of the first elastic element 654 is designed to be less than the clamping force of the elastic piercing fixed layer 3 for the needles, ensuring that the needle will not be pushed out by the first elastic element 654 under normal use.

[0033] Working principle: During the operation, after the surgeon or assistant completes a suturing operation, the surgeon holds the used suture needle with the needle holder and aligns the needle tip with the pressing guide area 2 on the upper surface of the circular body 1, that is, the center of the cross groove. Since the diameter of the cross groove is larger than the diameter of the suture needle and has a cross-shaped opening, the needle tip can be easily guided to the bottom of the groove. The operator applies a pressing force of about 1 to 3 Newtons vertically downward. After the needle tip pierces the pressing guide area 2, it enters the elastic puncture fixation layer 3 below. This elastic fixation layer is made of medical silicone and has elastic self-healing properties. When the suture needle body is inserted, the silicone is squeezed and deformed. After the needle body enters, the silicone relies on the elastic recoil force to tightly wrap the needle body, thereby firmly fixing the suture needle inside the circular body 1. Even if the circular body is inverted, it will not fall off.

[0034] Meanwhile, as the operator continues to press down, the needle tip gradually penetrates the entire thickness of the elastic fixing layer. When the needle tip emerges from the lower surface of the elastic fixing layer, it will directly contact the upper surface of the lower pressure plate 651 in the drive component 65. After the lower pressure plate 651 is pushed downward by the needle tip, it moves axially downward in the rotating cylinder 61. The protrusion 652 fixed on the side of the lower pressure plate 651 moves downward accordingly. Since the protrusion 652 is slidably connected in the spiral groove 653 of the rotating cylinder 61, and the rotating cylinder 61 is rotatably connected to the bottom layer 4 and cannot move axially, the linear movement of the protrusion 652 forces the rotating cylinder 61 to rotate around its axis. During the downward movement of the lower pressure plate 651, the first elastic element 654 inside the rotating cylinder 61 is gradually compressed.

[0035] When the rotating drum 61 rotates, the connecting rod 62 fixed to its outside drives the arc-shaped color plate 63 to rotate together. The arc-shaped color plate 63 is initially completely inserted inside the arc-shaped sleeve 64 and cannot be seen from the side wall of the disc body 1. As the rotating drum 61 rotates, the connecting rod 62 pushes the arc-shaped color plate 63 out of the arc-shaped sleeve 64 along the arc trajectory. Finally, the arc-shaped color plate 63 is fully exposed, and the red color block on it can be seen through the side wall of the disc body 1, clearly indicating that the disc has been used.

[0036] When the operator releases the suture needle, the clamping force of the suture needle body on the elastic insertable fixing layer 3 is much greater than the rebound force of the first elastic element 654, so the suture needle will not automatically pop out. At this time, the pressure plate 651 is still against the bottom of the suture needle tip and remains in the pressure state. The first elastic element 654 remains in the compressed state, and the arc-shaped color plate 63 also remains in the sliding position. This means that as long as the suture needle is still inside the disc, it will always show that it has been used, which makes it convenient for the nurse to check at any time.

[0037] When postoperative counting or processing is required, the nurse uses needle forceps or manually to pull the suture needle out of the elastic fixation layer. During the pulling process, the needle tip gradually detaches from the upper surface of the lower pressure plate 651, and the lower pressure plate 651 loses downward pressure. At this time, the first elastic element 654 releases the stored elastic potential energy, pushing the lower pressure plate 651 to move upward and reset. When the lower pressure plate 651 rises, the protrusion 652 slides in the opposite direction in the spiral groove 653, driving the rotating cylinder 61 to rotate in the opposite direction. The connecting rod 62 drives the arc-shaped color plate 63 to retract back into the arc-shaped sleeve 64. The red color block of the arc-shaped color plate 63 can no longer be seen on the side wall of the disc body 1. At this time, the disc has completed a complete use cycle.

[0038] Example 2:

[0039] As attached Figure 5 To be continued Figure 7As shown, this embodiment is basically the same as the previous embodiment, except that it also includes a buckle assembly 7. The buckle assembly 7 detachably connects multiple circular body 1s to form a group. The buckle assembly 7 allows each circular body to be used independently or combined as needed, which facilitates the overall management of the number of sutures by the surgical nurse.

[0040] The snap-fit ​​assembly 7 includes a connecting seat 71 and an insert block 73 fixedly connected to the outside of the circular body 1. The connecting seat 71 and the insert block 73 are respectively disposed on both sides of the circular body 1. The connecting seat 71 has two symmetrically formed slots 72, and the insert block 73 has a receiving cavity 74. The two ends of the receiving cavity 74 are symmetrically slidably connected to the locking blocks 75. A second elastic member 76 is disposed in the receiving cavity 74, and the two ends of the second elastic member 76 are respectively connected to the two locking blocks 75. The connecting seat 71 is fixedly connected to the outside of one side of the circular body 1, and has two symmetrically formed slots 72. The connecting seat 71 serves as a female end that mates with the insert block 73 on the adjacent circular body, used to receive the insertion of the insert block 73 and provide a snap-fit ​​fixing point. The slots 72 are used to mate with the locking blocks 75 on the insert block 73. When the locking block 75 is engaged in the slot 72, the two circular bodies 1 are locked together. The insert block 73 is fixedly connected to the outside of the other side of the circular body 1 (the side opposite to the connecting seat 71). The receiving cavity 74 is... A cavity inside the insert 73 is used to accommodate the locking block 75 and the second elastic member 76. The two ends of the receiving cavity 74 are symmetrically opened to allow the locking blocks 75 to extend out. There are two locking blocks 75, which are symmetrically slidably connected to the two ends of the receiving cavity 74. The outer end of the locking block 75 can extend out of the insert 73 to engage with the slot 72 of the connecting seat 71. The inner end of the locking block 75 contacts the second elastic member 76. Squeezing the two locking blocks 75 can make them move relative to each other, thereby disengaging them from the slot 72 and achieving disassembly. The second elastic member 76 can be a compression spring. The second elastic member 76 is located inside the receiving cavity 74, and its two ends are respectively connected to the two locking blocks 75. The second elastic member 76 is always in a compressed state, applying an outward pushing force to the two locking blocks 75, so that the locking blocks 75 automatically remain engaged with the slot 72 when no external force is applied. When disassembly is required, squeezing the two locking blocks 75 overcomes the elastic force of the second elastic member 76, causing the locking blocks 75 to retract, and the insert 73 can be pulled out of the connecting seat 71.

[0041] Working principle: First, before the operation, the nurse can select the corresponding number of circular pieces 1 according to the number of sutures required for the operation, and connect them into a strip by means of the buckle assembly 7. The specific connection method is as follows: Align the insert 73 on one side of the first circular piece 1 with the connecting seat 71 on the other side of the adjacent circular piece 1, and push the insert 73 into the opening of the connecting seat 71. During the pushing process, the locking blocks 75 at both ends of the insert 73 are squeezed by the inner wall of the connecting seat 71, and retract into the receiving cavity 74 against the elastic force of the second elastic element 76. When the insert 73 is pushed into place, the locking blocks 75 are aligned with the slots 72 on the connecting seat 71. The second elastic element 76 pushes the two locking blocks 75 outward, so that the locking blocks 75 are firmly locked into the slots 72, completing the locking between the two circular pieces. Repeat this operation to connect multiple circular pieces into a group. Each circular piece has a unique number on the outside.

[0042] During the surgery, after the surgeon or assistant finishes using a suture needle, they directly press it into the corresponding numbered disc. The color-indicating component 6 of that disc is triggered, and the arc-shaped color plate 63 slides out, which can be viewed through the side wall of the disc body 1, clearly indicating that the disc has been used. The nurse can observe the color plate status of each disc at any time and intuitively know which numbered discs have been used and which have not. During the postoperative count, the nurse only needs to check whether all discs have been colored, or quickly find the uncolored discs according to the number sequence, so as to determine whether any suture needles have not been retrieved. If a disc needs to be used alone, or if the discs need to be removed and processed separately after the operation, the locking blocks 75 on both sides of the insert 73 can be pinched with fingers to retract the locking blocks 75 and disengage them from the slot 72, thus separating the disc from the connecting group.

[0043] The snap-fit ​​component 7 enables the modular combination and separation of multiple circular pieces, transforming the counting process from counting needles to observing color swatches and numbers. This significantly reduces the counting difficulty and error rate, making it particularly suitable for large surgeries that require a large number of needles.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
