Description

Technical Field

[0001] The present invention relates to the technical field of skin staplers, in particular to a skin stapler. Background Art

[0002] Skin suturing is a basic surgical technique. After suturing, the patient needs to remove the sutures. Traditional nodule sutures will leave large scars, affecting the appearance. After years of clinical application in general surgery, orthopedics, obstetrics and gynecology, burns, emergency, cardiothoracic surgery, neurosurgery and other surgical departments, the skin stapler has been proven to be fast and simple in the process of epidermal suturing of long wounds. It is a major reform in suturing technology, a good assistant to surgeons, and a medical product worthy of promotion and application.

[0003] In the related art, there are devices that use zippers or similar structures to assist in suturing. For example, CN101785687A discloses a postoperative skin wound suture device, which includes two adhesive stickers arranged along both sides of the wound, the back of the adhesive sticker is an adhesive surface, and a plurality of wire buckles are fixed on the front of the adhesive sticker. The tension wire passes through and connects the wire buckles on both sides of the wound, but the pinching distance of the skin on both sides of the wound is fixed, and it is impossible to maintain uniform tension after suturing, which can easily cause the wound to crack after a long time or excessive movement after suturing, resulting in wound healing failure; and it can only sew straight wounds. When suturing arc-shaped wounds or irregular wounds, the skin on both sides of the wound will be uneven or cannot be sutured, leaving scars; the tension wire repeatedly passes through the wire buckles, and the force is uneven. Excessive tightening or adjacent locking devices cause the skin on both sides of the wound to be dislocated, affecting wound healing; and the distance between adjacent wire buckles is fixed, which is not conducive to adjustment according to the wound condition. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1, reference Figure 1-Figure 5 This embodiment provides a skin suture device, including a fixing member 1 and a tightening member 2; the fixing member 1 includes a fixing strip 11, a movable block 12 and an adhesive strip 13, the bottom of the fixing strip 11 is fixedly connected to the adhesive strip 13, the top of the fixing strip 11 is raised to form a guide rail 111, the guide rail 111 is slidably connected to the movable block 12, and the top of the movable block 12 is fixedly connected to the fixed block 14, the fixed block 14 is provided with a first through hole 141, the inner wall of the first through hole 141 is fixedly connected to one end of a spring sheet 142; the adhesive strip 13 uses a double-sided tape bottom surface for sticking and fixing on the skin.

[0032] The tightening member 2 is composed of a plurality of clamping strips 21 connected in sequence. A ratchet groove 22 is formed on the clamping strip 21 . The ratchet groove 22 engages with the other end of the spring piece 142 .

[0033] Preferably, in this embodiment, two fixing strips 11 of the same structure are fixed to both sides of the skin by adhesive strips 13. The fixing strips 11 are made of flexible materials, such as plastic. The fixing strips 11 can be bent and adjusted according to the shape of the wound. For example, if the wound is arc-shaped, the fixing strips 11 can be bent into an arc accordingly so that the fixing strips 11 fit the wound, thereby avoiding uneven skin on both sides of the wound or inability to suture, resulting in scars. Then, the movable block 12 is moved on the guide rail 111 to adjust the position of the movable block 12. At a deeper wound, the spacing between the movable blocks 12 is adjusted to be smaller to facilitate fixation of the skin near the wound. At a shallower wound, the spacing between the movable blocks 12 is adjusted to be larger to reduce the use of the movable blocks 12, thereby More wounds can be sutured, which is beneficial to saving the use of medical resources. It is more convenient to use and can be adjusted according to the condition of the wound, while ensuring the fixation effect of the skin near the wound; after the clamping strip 21 passes through the inner wall of the first through hole 141, the ratchet groove 22 on the clamping strip 21 is clamped by the spring sheet 142, so that the clamping strip 21 can only move in one direction, which can provide uniform pulling force on the skin near the wound, and the operation is simple and the suturing is rapid, which can effectively avoid the wound from cracking and causing wound healing failure; and the tightening member 2 is composed of a plurality of clamping strips 21 connected in sequence. After fixing the skin on both sides of the wound, the redundant clamping strips 21 can be removed so that the clamping strip 21 can be reused, and the clamping strip 21 is prevented from being too long and involving the wound when the wounded moves.

[0034] Example 2, reference Figures 1-9 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that.

[0035] Reference Figure 5 and Figure 6 One end of the card strip 21 is fixedly connected to the mounting block 23 , and the other end of the card strip 21 is provided with a mounting groove 212 , and the mounting blocks 23 on the adjacent card strips 21 are slidably connected to the inner wall of the mounting groove 212 .

[0036] In this embodiment, preferably, the mounting blocks 23 on adjacent clamping strips 21 can be inserted into the inner wall of the mounting groove 212, and the adjacent clamping strips 21 are combined to form a tightening member 2. When in use, after the tightening member 2 is passed through the inner wall of the first through hole 141, the ratchet groove 22 on the clamping strip 21 is clamped by the spring piece 142, so that the clamping strip 21 can only move in one direction, which can provide a uniform pulling force on the skin near the wound. In addition, the operation is simple and the suturing is fast, which can effectively prevent the wound from cracking and causing wound healing failure.

[0037] Reference Figure 6 and Figure 7 A second through hole 211 is provided on the mounting block 23 , an accommodating groove 213 is provided on the inner wall of the mounting groove 212 , a card block 214 is slidably connected to the inner wall of the accommodating groove 213 , and a first inclined surface 215 is provided on one side of the card block 214 .

[0038] In this embodiment, preferably, the block 214 can slide on the inner wall of the receiving groove 213. When the mounting block 23 is inserted into the inner wall of the mounting groove 212, the block 214 slides to the inner wall of the receiving groove 213. Figure 7 At this time, a portion of the clamping block 214 is inserted into the second through hole 211, which can fix the mounting block 23 and fix adjacent clamping strips 21 together to form a tightening member 2.

[0039] Reference Figure 6 and Figure 7 The other side of the block 214 is fixedly connected to one end of the first spring 216 , and the other end of the first spring 216 is fixedly connected to the inner end wall of the accommodating groove 213 .

[0040] In this embodiment, preferably, when the mounting block 23 is inserted into the inner wall of the mounting groove 212, the mounting block 23 pushes the first inclined surface 215 to compress the first spring 216, and the mounting block 23 continues to move. When the second through hole 211 is aligned with the clamping block 214, the clamping block 214 slides to the inner wall of the mounting groove 212 under the action of the elastic force of the first spring 216. Figure 7 At this time, a portion of the clamping block 214 is inserted into the second through hole 211, which can fix the mounting block 23 and fix adjacent clamping strips 21 together to form a tightening member 2.

[0041] Reference Figure 6 and Figure 7 The block 214 is fixedly connected to one end of the telescopic rod 217 , and the other end of the telescopic rod 217 is fixedly connected to the inner end wall of the accommodating groove 213 . The first spring 216 is sleeved on the telescopic rod 217 .

[0042] In this embodiment, preferably, under the action of the elastic force of the first spring 216, the block 214 slides to Figure 7 When a portion of the card block 214 is inserted into the second through hole 211, the telescopic rod 217 extends accordingly. When the telescopic rod 217 contracts, the telescopic rod 217 pulls the card block 214 to move, so that the card block 214 is pulled out of the second through hole 211. At this time, the mounting block 23 can be pulled out from the inner wall of the mounting groove 212, so that the adjacent card strips 21 are separated.

[0043] Reference Figure 7-Figure 9 A bottom hole 218 is provided on the clamping strip 21, and the inner end wall of the bottom hole 218 is fixedly connected to one end of the second spring 219, and the other end of the second spring 219 is fixedly connected to the first piston head 201, and the first piston head 201 is slidably connected to the inner wall of the bottom hole 218.

[0044] The telescopic rod 217 includes a fixed cylinder 2171, a second piston head 2172 and a movable rod 2173. The fixed cylinder 2171 is fixedly connected to the inner end wall of the accommodating groove 213. The inner wall of the fixed cylinder 2171 is slidably connected to the second piston head 2172. The second piston head 2172 is fixedly connected to one end of the movable rod 2173. The other end of the movable rod 2173 is fixedly connected to the block 214. The fixed cylinder 2171 is connected to the inside of the bottom hole 218 through the connecting tube 202.

[0045] In this embodiment, when it is necessary to separate the adjacent clamping strips 21, an L-shaped hook is used to extend from the bottom of the clamping strip 21, so that the hook contacts the first piston head 201, and the first piston head 201 is pulled up. Figure 8 The first piston head 201 compresses the second spring 219 and the air on the inner wall of the bottom hole 218. The air enters the fixed cylinder 2171 through the connecting tube 202. At this time, the second piston head 2172 is pushed to move under the action of air pressure. The second piston head 2172 drives the movable rod 2173 to move. The overall length of the telescopic rod 217 is shortened. The telescopic rod 217 pulls the clamping block 214 to move, so that the clamping block 214 is pulled out of the second through hole 211. At this time, the mounting block 23 can be pulled out from the inner wall of the mounting groove 212, so that the adjacent clamping strips 21 are separated.

[0046] Reference Figure 1 A groove 143 is formed on the inner wall of the first through hole 141 at a position corresponding to the spring piece 142 .

[0047] Preferably, in this embodiment, after the clamping strip 21 passes through the inner wall of the first through hole 141 , the ratchet groove 22 on the clamping strip 21 is clamped by the spring piece 142 , so that the clamping strip 21 can only move in one direction, and the groove 143 is used to accommodate the spring piece 142 squeezed by the clamping strip 21 .

[0048] Reference Figure 1 The fixing strip 11 is made of a flexible material, such as plastic. The fixing strip 11 can be bent and adjusted according to the shape of the wound. For example, if the wound is arc-shaped, the fixing strip 11 can be bent into an arc accordingly so that the fixing strip 11 fits the wound, avoiding uneven skin on both sides of the wound or inability to suture, resulting in scars.

[0049] Reference Figure 5 The clamping strip 21 defines a second inclined surface 231 near the mounting block 23 .

[0050] Preferably, in this embodiment, the second inclined surface 231 facilitates guiding the clip 21 to be inserted into the first through hole 141 , which is beneficial for quickly suturing the skin near the wound.

[0051] The working principle is that two fixing strips 11 with the same structure are fixed on both sides of the skin through adhesive strips 13. The fixing strips 11 are made of flexible materials, such as plastic. The fixing strips 11 can be bent and adjusted according to the shape of the wound. For example, if the wound is arc-shaped, the fixing strips 11 can be bent into an arc accordingly so that the fixing strips 11 fit the wound, thereby avoiding uneven skin on both sides of the wound or inability to sew, resulting in scars. Compared with the existing suturing method with staples, there is no need to remove the staples later, and no skin puncture is performed, which is conducive to reducing skin scars.

[0052] The movable block 12 is moved on the guide rail 111 to adjust the position of the movable block 12. When the wound is deeper, the spacing of the movable block 12 is adjusted to be smaller to facilitate fixation of the skin near the wound. When the wound is shallow, the spacing of the movable block 12 is adjusted to be larger to reduce the use of the movable block 12, so that more wounds can be sutured, which is beneficial to saving the use of medical resources. It is more convenient to use and can be adjusted according to the condition of the wound while ensuring the fixation effect of the skin near the wound.

[0053] After the clamping strip 21 passes through the inner wall of the first through hole 141, the first piston head 201 faces downward, that is, toward the place close to the skin, to prevent the first piston head 201 from being touched by mistake, causing the clamping strip 21 to separate. The ratchet groove 22 on the clamping strip 21 is stuck by the spring sheet 142, so that the clamping strip 21 can only move in one direction, which can provide uniform pulling force on the skin near the wound. In addition, the operation is simple and the suturing is quick, which can effectively avoid the wound from cracking and causing wound healing failure.

[0054] Use an L-shaped hook to extend from the bottom of the card strip 21 to make the hook contact with the first piston head 201. At this time, press the fixing strip 11 with your hand to prevent the adhesive strip 13 from loosening. After pulling up the hook, the first piston head 201 moves to the Figure 8 The first piston head 201 compresses the second spring 219 and the air on the inner wall of the bottom hole 218, and the air enters the fixed cylinder 2171 through the connecting tube 202. At this time, the second piston head 2172 is pushed to move under the action of air pressure, and the second piston head 2172 drives the movable rod 2173 to move. The overall length of the telescopic rod 217 is shortened, and the telescopic rod 217 pulls the card block 214 to move, so that the card block 214 is pulled out from the second through hole 211. At this time, the mounting block 23 can be pulled out from the inner wall of the mounting groove 212, so that the adjacent card strips 21 are separated. Compared with the existing method of fixing with a cable tie, the cable tie itself has a very high structural strength. It requires a relatively large force when cutting. At the moment of disconnection, there will be strong vibration, which can easily involve the wound, causing severe pain, causing secondary injury, and affecting wound recovery.
