Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical suture pull tab that is easy to clean. Background Technology

[0002] Skin wounds, especially surgical wounds, are often linear and are usually sutured with medical needles and sutures. This not only requires a longer suturing time, increasing the surgical risk for the patient, but also necessitates the removal of sutures after the wound has healed, leaving a "centipede"-like scar at the wound site, which is unsightly and affects appearance.

[0003] A convenient medical suture puller disclosed in announcement number CN208741047U effectively solves the problems of inconvenient wound suturing and scarring after suture removal. The technical solution includes a horizontal release paper with multiple rectangular blocks fixed to its upper surface. Multiple fixing blocks are located to the right of the rectangular blocks, and pins connect the rectangular blocks to the fixing blocks. Each fixing block has a blind hole with a baffle at its left end. An annular plate is located within the through hole, and a compression spring connects the right end of the annular plate to the bottom of the blind hole. A metal ball is located within the blind hole, positioned to the left of the annular plate and in contact with its left end. A rope is connected to each metal ball, with its left end connected to the metal ball and its right end passing through the annular plate and the bottom of the blind hole from left to right. The right end of the rope is positioned to the right of the fixing block, which has a pull block on its right side. The pin has an annular groove. This invention has an ingenious structure, facilitating surgical wound suturing and significantly reducing scarring after suture removal.

[0004] However, this convenient medical suture pull tab has the following disadvantages:

[0005] 1. The fixed position of the annular groove on the surface of the pin restricts the traction range of the wound edge during use, making it difficult to adapt to the wound closure requirements of different depths or tensions.

[0006] 2. The method of fixing the wound by pulling one side of the pin to insert into the other side may result in uneven force on both sides of the wound, causing local tissue compression or blood supply obstruction, which will affect the quality of healing. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a medical suture pull tab that is easy to clean and has the following beneficial effects:

[0019] 1. This easy-to-clean medical suture pull tab, through the design of a fixing block, guide groove, double-buckle mechanism, and locking mechanism, allows for easy operation. First, remove the release paper, then attach the medical suture pull tabs to both sides of the wound. Insert the pull tab strip into the guide groove of the opposing fixing block, pull the pull rings on both sides, and use the spring-driven buckle to engage the locking tension, keeping the wound everted and aligned. The pull tab strip length is adjustable to suit different wound surfaces. During cleaning, pulling the pull rod moves the buckle away from the groove of the pull tab strip, allowing for quick removal and thorough exposure of the wound surface for efficient debridement. The balanced force applied from both sides effectively avoids uneven force caused by unilateral traction, significantly reducing the risk of local tissue compression and blood supply obstruction, promoting healing quality. The detachable pull tab strip also facilitates wound cleaning, avoiding difficulties in wound care.

[0020] 2. This easy-to-clean medical suture pull tab, through the design of release paper and a self-cleaning mechanism, features a nano-silver ion antibacterial layer on its surface that effectively inhibits the growth of common pathogens, reducing the risk of biofilm formation on the wound contact surface. The middle layer contains a replaceable activated carbon filter that can directionally absorb exudate from the wound, preventing colloidal adhesion and skin maceration caused by exudate accumulation. To replace the filter, simply tear open the tear strip, remove the contaminated filter through the insertion port, insert the new filter, and then attach the tear strip to the top of the antibacterial layer. This reduces secondary trauma caused by frequent tape changes and effectively avoids the problems of irritant dermatitis and cross-infection caused by the short antibacterial effect and exudate retention of traditional fixation materials.

An antibacterial layer 302 is provided above the two sets of adhesive layers 301. The middle of the adhesive layers 301 and the antibacterial layer 302 is inserted. The filter screen 303 is attached, and an insertion port 304 is provided above the antibacterial layer 302. A tearable strip 305 is adhesively connected to one side of the insertion port 304. The double buckle mechanism 4 includes a pull strip 401 provided on one side of the guide groove. Several sets of slots 402 are provided on one side of the pull strip 401. The locking mechanism 5 includes two sets of grooves provided on the inner side wall of the guide groove. A pull rod 501 is connected through one side of the two sets of grooves. A spring 502 is sleeved on the surface of the pull rod 501. A buckle 503 is fixedly connected to one side of the pull rod 501.

[0029] The bottom of the fixing block 2 is provided with a bearing substrate 6. Several sets of bearing substrates 6 are evenly arranged above the antibacterial layer 302. The bearing substrates 6 play a supporting and fixing role.

[0030] Two sets of fixing blocks 2 are symmetrically distributed above the two sets of antibacterial layers 302. The pull strips 401 on one side of the two sets of fixing blocks 2 are inserted into the guide grooves of the opposite fixing blocks 2. The pull strips 401 are used to lock the fixing blocks 2 on both sides.

[0031] The pull rod 501 is connected through to one side of the fixing block 2. The diameter of the pull rod 501 is smaller than the diameter of the buckle 503. The pull rod 501 facilitates the disassembly of the buckle strip 401.

[0032] A pull ring 7 is provided on the side of the pull strip 401 away from the fixing block 2. The size of the slot 402 is adapted to the size of the buckle 503. The pull ring 7 facilitates the pulling of the pull strip 401.

[0033] The filter mesh 303 is made of activated carbon particles and non-woven fabric composite, and the antibacterial layer 302 is made of nano silver ions. The antibacterial layer 302 helps to reduce wound infection.

[0034] The adhesive layer 301 is made of medical-grade acrylic pressure-sensitive adhesive. The adhesive layer 301 is directly attached to the external skin, and through its design, it achieves a gentle adhesion to the skin.

[0035] In this invention, the working steps of the device are as follows:

[0036] First step: During operation, first tear off the release paper 1, then attach the medical suture pull tabs to both sides of the wound, insert the pull tab strip 401 into the guide groove of the opposing fixing block 2, pull the pull rings 7 on both sides, and use the spring 502 to drive the buckle 503 to embed into the groove and lock the tension, so that the wound is kept everted and aligned. The length of the pull tab strip 401 can be adjusted to adapt to different wound surfaces. When cleaning, pull the pull rod 501 to make the buckle 503 move away from the groove of the pull tab strip 401. The pull tab strip 401 can be quickly disassembled to completely expose the wound surface and achieve efficient debridement.

[0037] The second step: When using the medical suture tape, the nano-silver ion antibacterial layer 302 on the surface can effectively inhibit the growth of common pathogens. The middle layer is embedded with a replaceable activated carbon filter 303, which can directionally absorb the fluid exuded from the wound. When replacing, tear open the tear strip 305, take out the contaminated filter 303 through the insertion port 304, put in the new filter 303, and then stick the tear strip 305 to the top of the antibacterial layer 302 to reduce secondary trauma caused by frequent tape replacement.
