Description

Technical Field

[0001] The present invention relates to a medical wound suturing device. Background Art

[0002] Generally speaking, human skin is an organ that covers the outside of the body and is composed of three layers: the epidermis, the dermis, and the subcutaneous fat layer.

[0003] Of the three layers that make up the skin, the epidermis is characterized by being mostly composed of keratinocytes. The dermis, located beneath the epidermis, contains blood vessels, nerves, and sweat glands, all made up of matrix proteins such as collagen and elastin fibers. Furthermore, the subcutaneous fat layer is composed of fat cells. The skin, composed of these three layers, not only plays an important role in regulating body temperature but also protects the body from the external environment.

[0004] Such skin layer may be cut and damaged due to accidents caused by carelessness. Since the damaged skin is at risk of bacterial infection from the outside, in order to prevent bacterial infection and treat the wound, it is preferred to suture the wound site to restore the wound site.

[0005] Generally speaking, a torn wound on the skin surface or a wound incised due to surgery is sutured with medical thread (suture thread), and then the sutured medical thread (suture thread) is removed after a certain period of time, thereby performing surgery to suture the wound.

[0006] However, in such suturing methods using silk threads (suture threads), additional surgical procedures are required to sew up the torn wound sites on the skin surface or the wound sites that were incised during surgery one by one with silk threads, and the suturing silk threads must be removed after a certain period of time, resulting in a very cumbersome operation. Furthermore, even after the wound sites suturing with silk threads have healed, surgical scars such as traces of the suturing with silk threads remain, which can be visually unsightly.

[0007] In order to solve the above-mentioned problems, Korean Patent Laid-Open Publication No. 10-2015-0105757 discloses a skin suturing assembly capable of suturing incised skin without using silk sutures.

[0008] The prior art discloses a skin suturing assembly for suturing incised skin, characterized in that it includes: a first coupling member, which is attached to the skin on one side based on the incised wound; a second coupling member, which is attached to the skin on the other side based on the incised wound; a connecting strip, which connects the first coupling member and the second coupling member, and forms a coupling force with one or more coupling members of the first coupling member and the second coupling member by friction or locking; and a control rod, which is formed on the first coupling member and the second coupling member, respectively, and is used for finger locking so that the distance between the first coupling member and the second coupling member can be adjusted with one hand. According to the skin suturing assembly, it has the advantages of not leaving scars caused by suturing surgery, and even if the wound to be sutured is long, it can be retracted along the length direction, and a stretched wound can be retracted with only one hand.

[0009] However, a problem with the suturing assembly is that, since the control rods for pulling the connecting strips are attached individually, it takes a long time when the wound area is long, and the control rods need to be pulled sequentially multiple times to sew up the skin. This not only causes multiple pains, but also, if the pulling degrees of each control rod are different, the skin suturing becomes uneven, which may leave an ugly surgical scar. Furthermore, after the wound heals, it is difficult to confirm whether the sutured area, which may affect the occurrence of scars, has been properly sutured.

[0010] In addition, as another suturing technology, a wound suturing device disclosed in Korean Patent Publication No. 10-2019-0084257 discloses a technology for suturing wounds using taping instead of suture thread.

[0011] However, in the technology utilizing the taping method as described above, since relatively more positions in the wound site are taped, not only does it have the problem of complicated disinfection of the suture site, but it also has the disadvantage of having limitations in presenting sufficient suture retention due to the taping method.

[0012] Furthermore, although Korean Patent Gazette No. 10-2243126 discloses a medical skin suturing device that does not use suture thread, it uses a combination of multiple inner and outer screws and utilizes a force acting in a unilateral direction to sew the wound area. At this point, there is a problem that not only does it cause the suture area to be formed inconsistently, but it may also be accompanied by pain in the wound area during the process of adjusting the screws.

[0013] Therefore, there is an urgent need to develop a novel wound closure device that can solve the problems of the existing prior art.

[0062] The following is a detailed description of the present invention with reference to the accompanying drawings. The embodiments described below are provided as examples to fully convey the technical concepts of the present invention to ordinary practitioners. Therefore, the present invention is not limited to the embodiments described below, but can be embodied in other forms. In addition, in the drawings, the size and thickness of the device may be exaggerated for convenience. Throughout the specification, the same reference numerals represent the same components.

[0063] Refer to the attached Figure 1 The advantages, features and methods of implementing the present invention will be clearly understood by the embodiments described below. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms that are different from each other. This embodiment is provided to fully disclose the present invention and to fully indicate the scope of the present invention to those skilled in the art to which the present invention belongs. The present invention is defined only by the appended claims. Throughout the specification, the same reference numerals represent the same components. In the drawings, the size and relative size of each component may be exaggerated for clarity of illustration.

[0064] The term "wound" used in this specification may refer to any physical injury occurring in an organism such as a human or an animal.

[0065] The term "cut portion" used in this specification may refer to a state of being torn or pulled apart.

[0066] The term "sewing" used in this specification may refer to any action of restoring a torn or stretched state to a state of being joined again.

[0067] The term "inside" used in this specification is a relative concept, and may refer to a state located at a center portion.

[0068] The term "outside" used in this specification is a relative concept and may refer to a state of being located outside relative to the center.

[0069] The term "blocked" used in this specification is defined to mean not only a structure in which a part of an area is completely blocked so that the traction member of the present invention cannot pass through or separate, but also a case in which a part of the corresponding area is blocked to such an extent that the traction member of the present invention cannot pass through or separate.

[0070] The terms used in this specification are used to illustrate the embodiments and are therefore not intended to limit the present invention. In this specification, unless otherwise specified in a sentence, a singular expression includes a plural expression. The words "comprise" and / or "comprising" used in the specification do not exclude the presence or addition of one or more other constituent elements, steps, actions and / or elements other than the constituent elements, steps, actions and / or elements mentioned.

[0071] As mentioned above, in the prior art related to wound staplers used for suturing wounds without using suture thread, it takes a long time to apply the wound, and due to the suturing method and the structural characteristics of the wound stapler, there are problems such as not only causing pain to the wound area during application to the wound area and suturing, but also limitations in the suture retention force. Therefore, research and development in related technical fields to overcome such problems are continuously being conducted.

[0072] Among them, in order to overcome the above-mentioned problems, Korean Patent No. 10-2585783 discloses a structural feature in which a central portion of a main body of a guide member, which is a portion through which a traction member passes, includes groove portions open at the front, rear, and top. Through such a structure, it discloses a technical feature that when the length of the traction member is adjusted, the traction member can be separated from the open top of the groove portion by lifting the traction member upward, thereby minimizing the pain caused.

[0073] Furthermore, in the aforementioned prior authorized patent, as the structural feature of lifting and separating the traction member above the groove portion is adopted, the problem of the traction member being easily separated from the guide member will inevitably occur during the process of using the wound suture device in a state of being attached. In order to solve such a problem, it is disclosed that a structural feature of additionally forming a blocking block and an anti-separation member on the groove portion is disclosed.

[0074] However, in the wound stapling device disclosed in the aforementioned patent, in order to minimize the pain caused by readjusting the length of the traction member, the traction member is lifted up, separated from the guide member, and then reattached to the groove portion. This method not only still has the disadvantage of causing pain, but also has the disadvantage of unevenly adjusting the height of the wound site during the process of reattaching the traction member after lifting it up, which may cause scarring in the future. Furthermore, although the groove portion has an anti-detachment member, it is still insufficient to fully prevent the traction member from detaching from the guide member in real life environments.

[0075] In this regard, the applicant recognizes the problems existing in the existing prior granted patents, and in order to overcome such problems, aims to provide a wound suture device, which includes a structural feature that can be separated "laterally" (rather than upwardly) when the length of the traction member 30-2 needs to be adjusted.

[0076] According to one embodiment of the present invention, a medical wound suturing device may include a pair of adhesive sheets 1 that can be attached to the skin on both sides of the wound site, and a pair of suturing units 30. The suturing units 30 include: a fixing portion 30-1, which is formed separately on each adhesive sheet 1; a traction member 30-2, one end of which is attached to each fixing portion 30-1 and extends in the direction of the adhesive sheets 1 relative to each other; and a handle portion 30-3, which is attached to the other end of each traction member 30-2. The fixing portion 30-1 includes: a traction member attachment portion 30-4; and a guide member 30-5, which is formed separately from the traction member attachment portion 30-4. The guide member 30-5 includes a groove portion 30-53 in the central portion of the main body, which is open at the front, rear, and one side.

[0077] In addition, the pulling member 30 - 2 of the sewing unit 30 may pass through the inside of the guide member 30 - 5 of the opposing sewing unit 30 and be connected to each other.

[0078] Figure 1 A perspective view of the medical wound suturing device of the present invention is shown. Figure 1 The medical wound suture device of the present invention comprises: a pair of adhesive sheets 1, which are attached to the skin on both sides based on the wound site; and a pair of suturing units 30, which are combined with the respective adhesive sheets 1 through fixing parts 30-1.

[0079] Specifically, refer to Figure 1Each of the two stitching units 30 is described. The stitching unit 30 includes two fixed portions 30-1 formed on each of the pair of adhesive sheets 1, separated from each other, and may include: two traction members 30-2, one end of which is attached to each of the two fixed portions 30-1 and extends toward the other adhesive sheet 1 not having the fixed portion 30-1 of the stitching unit 30; and a handle portion 30-3 attached to the other end of each traction member 30-2. Alternatively, the two traction members 30-2 may be attached to a single handle portion 30-3.

[0080] In addition, the fixing portion 30-1 of the suturing unit 30 includes a traction member fitting portion 30-4 and a guide member 30-5 formed separately from the traction member fitting portion 30-4, and the traction member 30-2 of the suturing unit 30 can pass through the interior (groove portion 30-53) of the guide member 30-5 of the relative suturing unit 30 and be connected to each other.

[0081] Specifically, the structure is characterized in that the two fixing portions 30-1 of each stitching unit 30 include guide members 30-5, which are separated from the traction member contact portion 30-4, which is the portion for the traction member 30-2 to contact. Specifically, the traction member 30-2 of either stitching unit 30 passes through the interior (groove portion 30-53) of the guide member 30-5 formed in the other stitching unit 30, thereby connecting the two stitching units 30 to each other.

[0082] Specifically, refer to Figure 1 or Figure 2 The connection structure of the sewing unit 30 in the two sewing units 30, which is combined with the first bonding sheet 10 through the fixing portion 30-1, is described. The sewing unit 30 includes two fixing portions 30-1 on the first bonding sheet 10, and two traction members 30-2 can respectively pass through the interior of the two guide members 30-5 (groove portions 30-53) and be connected. The traction members 30-2 extend from the respective fixing portions 30-1 toward the direction of the second bonding sheet 20, and the guide members 30-5 are formed in the sewing unit 30 combined with the second bonding sheet 20 through the fixing portion 30-1.

[0083] In addition, in the same manner as described above, the sewing unit 30 coupled to the second bonding sheet 20 via the fixing portion 30-1 includes two fixing portions 30-1 on the second bonding sheet 20, and the two traction members 30-2 can respectively pass through the interior of the two guide members 30-5 (groove portions 30-53) and be connected, and the traction members 30-2 are formed extending from the respective fixing portions 30-1 toward the direction of the first bonding sheet 10, and the guide members 30-5 are formed in the sewing unit 30 coupled to the first bonding sheet 10 via the fixing portion 30-1.

[0084] Preferably, Figure 2 A top view of a medical wound suturing device according to an embodiment of the present invention is shown. Figure 2 The medical wound suturing device of the present invention may include: a first adhesive sheet 10 and a second adhesive sheet 20, each capable of being attached to skin on both sides based on a wound site; a first suturing unit 31, comprising a first fixing portion 31-1a and a second fixing portion 31-1b formed separately on the first adhesive sheet 10, a first traction member 31-2a and a second traction member 31-2b having one end attached to the fixing portions and extending toward the second adhesive sheet 20, and a handle 31-3 attached to the other end of each traction member; and a second suturing unit 32, comprising a third fixing portion 32-1a and a fourth fixing portion 32-1b formed separately on the second adhesive sheet 20, a third traction member 32-2a and a fourth traction member 32-2b having one end attached to the fixing portions and extending toward the first adhesive sheet 10, and a handle 32-3 attached to the other end of each traction member.

[0085] In more detail, the first sewing unit 31 and the second sewing unit 32 are connected to each other, and respectively include first to fourth guide members 31-5a, 31-5b, 32-5a, 32-5b formed separately from the first to fourth traction member fitting parts 31-4a, 31-4b, 32-4a, 32-4b formed on the first to fourth fixing parts 31-1a, 31-1b, 32-1a, 32-1b, the first traction member 31-2a and the second traction member 31-2b can respectively pass through the interior (groove part 30-53) of the fourth guide member 32-5b and the third guide member 32-5a, and the third traction member 32-2a and the fourth traction member 32-2b can respectively pass through the interior (groove part 30-53) of the second guide member 31-5b and the first guide member 31-5a, thereby connecting the first sewing unit 31 and the second sewing unit 32 to each other.

[0086] Specifically, when a pair of suturing units 30 are connected to each other using the structural features described above, each adhesive sheet 1 can provide a predetermined pulling force during the process of suturing the wound by pulling the handles 30-3 connected to each suturing unit 30 in opposite directions. This advantageously prevents the adhesive sheet 1 from being biased to one side. Furthermore, by providing a uniform pulling force to the wound, scar formation in the wound can be minimized.

[0087] In addition, the guide member 30 - 5 may include a groove portion 30 - 53 opened at the front, rear and one side thereof in the central portion of the main body.

[0088] Figure 4 A perspective view showing a suturing unit 30 as a structural element of the medical wound suturing device of the present invention is shown, in which the groove portion 30 - 53 of the guide member 30 - 5 can be identified.

[0089] Reference Figure 4 The guide member 30-5 is a structure formed on each fixing part 30-1 of the suturing unit 30, separated from the traction member bonding part 30-4 for bonding with the traction member 30-2. The guide member 30-5 has a structure in which a groove part 30-53 is formed in the central part of the main body with a flat bottom surface and is open in the front, rear and one side.

[0090] Specifically, the groove portion 30-53 is formed on the central part of the main body of the guide member 30-5 with a flat bottom surface, and its upper surface, lower surface and one side are closed, and its front, rear and one side opposite to the closed side are open.

[0091] In addition, the groove portion 30-53 may further include: a blocking block 30-51, which is formed to protrude from at least one of the upper surface and the lower surface of the guide member 30-5 toward the center direction of the groove portion 30-53.

[0092] Preferably, the groove portion 30 - 53 may include: a plurality of locking blocks 30 - 51 protruding from each of the upper surface and the lower surface of the guide member 30 - 5 toward the center of the groove portion 30 - 53 .

[0093] In this case, compared with a case where the clamping block 30 - 51 is formed separately, the traction member 30 - 2 can be fixed more firmly, thereby improving the suturing effect on the wound.

[0094] Figure 5 The cross section of the guide member as a structural element of the medical wound suturing device of the present invention is shown, in which the structure of the clamping blocks 30-51 of the present invention can be identified.

[0095] Reference Figure 5 The locking blocks 30-51 are structures that protrude from the upper and lower surfaces of the guide member 30-5 toward the center of the groove 30-53, respectively. The locking blocks 30-51 may include first and second locking blocks 30-51a and 30-51b, respectively, and serve as structures for locking the serrated portion of the locking portion 30-21 of the traction member 30-2 passing through the groove 30-53. The locking blocks 30-51 serve as structures that secure the traction member 30-2 while maintaining traction force while the user pulls the handles 30-3 formed on the two suturing units 30 leftward or rightward to sew the wound, thereby keeping the skin area, which has been stretched apart due to the wound, in a retracted state for a long period of time.

[0096] Preferably, the first and second clamping blocks 30-51a and 30-51b formed on the upper and lower surfaces of the guide member 30-5 are staggered to be respectively locked on the inclined surfaces or serrated portions of different locking portions 30-21.

[0097] That is, when the multiple blocks 30-51 are formed on the same axis and are locked on the inclined surfaces or serrated portions of the same locking portions 30-21, the degree of vibration generated when the traction member 30-2 formed with the locking portions 30-21 is pulled is large, which may cause pain in the wound area. The structural feature of the present invention is that the multiple blocks 30-51 are staggered with each other (rather than formed on the same axis) so that they are locked on the inclined surfaces or serrated portions of different locking portions 30-21.

[0098] As described above, when the blocks 30-51 are staggered with each other, there is an advantage that when the traction member 30-2 is pulled, the vibration generated when the locking portion 30-21 on the traction member 30-2 passes through the blocks 30-51 can be minimized. Furthermore, compared with the case where the blocks 30-51 are formed on the same axis, since the traction member 30-2 can be firmly fixed in a wider area, the slight shaking of the traction member 30-2 can be suppressed, thereby minimizing the pain at the wound site and maximizing the wound suturing effect.

[0099] More preferably, the plurality of latching blocks 30-51 formed on the upper and lower surfaces of the guide member 30-5 are staggered to each other and can be formed to latch the latching portions 30-21 at both ends of a region of two to five latching portions 30-21 continuously formed on the traction member 30-2. Figure 5The structure shown is formed so that a plurality of locking blocks 30 - 51 respectively lock the locking portions 30 - 21 existing at both ends of two ranges of the locking portion 30 - 21 area continuously formed on the pulling member 30 - 2 .

[0100] Specifically, when the number of the locking portions 30-21 fixable by the multiple locking blocks 30-51 of the present invention is within the range, the traction member 30-2 can be more firmly fixed while minimizing the vibration generated by pulling the traction member 30-2.

[0101] However, if the distance is less than the above range, the blocks 30-51 will be formed on the same axis, which may cause the aforementioned problem. Furthermore, if the distance is greater than the above range, the distance between the locking portions 30-21 that can be fixed by the blocks 30-51 will become too far apart, which may reduce the fixing effect of the traction member 30-2.

[0102] in addition, Figure 6 and Figure 7 It is an enlarged view of the guide member 30 - 5 according to the present invention.

[0103] Refer to the Figure 6 and Figure 7 When the traction member 30-2 is pulled, the hinge portion on the upper surface of the guide member 30-5 acts as a spring, thereby relaxing the locking structure of the block 30-51 of the traction member 30-2. Furthermore, it is characterized in that it prevents the traction member 30-2 from escaping to the side at ordinary times, and acts as a spring when the traction member 30-2 is separated to the side and can be pulled upward.

[0104] In addition, the first blocking block 30-51a of the groove portion 30-53 includes a semicircular groove, so that it can block a wider area relative to the inclined surface or serrated portion of the traction member locking portion 30-21. Similar to the hinge portion on the upper surface of the guide member 30-5 mentioned above, the two upper ends of the first blocking block 30-51a can act as springs, so that when the traction member 30-2 is pulled, the blocking block 30-51 can be opened in the direction of travel.

[0105] Refer to the Figure 6 and Figure 7 When the guide member 30-5 is opened, the side of the groove portion 30-53 may further include: an anti-separation member 30-52, which is protruded from the upper surface of the guide member 30-5 toward the center of the groove portion 30-53.

[0106] That is, the groove portion 30-53 includes the anti-separation member 30-52 on one side of the opening thereof. The anti-separation member 30-52 is a structure formed by protruding from the upper surface of the guide member 30-5 toward the center of the groove portion 30-53.

[0107] Furthermore, the anti-detachment member 30-52 is a structure for preventing the traction member 30-2 from being detached after passing through the groove 30-53. This prevents the traction member 30-2 from detaching while the user is carrying out their daily routine with the medical wound closure device of the present invention attached to the wound. Specifically, the wound closure device of the present invention, by including the anti-detachment member 30-52, maintains the skin area stretched by the wound in a retracted state while allowing the wounded body area to move normally.

[0108] In addition, in order to adjust the length of the traction member 30-2, the medical wound suture device can pull the traction member 30-2 in the side direction to separate the traction member 30-2 from the guide member 30-5, pull the traction member 30-2 in the opposite direction of the traction member bonding portion, and engage the traction member 30-2 in the groove portion 30-53 of the guide member 30-5 and fix it.

[0109] Specifically, when the length of the traction member 30-2 needs to be adjusted again as time passes after the wound occurs, the traction member 30-2 is pulled sideways to artificially separate the traction member 30-2 from the guide member 30-5 through the side of the guide member 30-5 that is not closed by the anti-separation member 30-52. Then, the traction member 30-2 can be additionally pulled or pushed to the left or right to the required length, and the traction member 30-2 can be connected and fixed to the groove portion 30-53 of the guide member 30-5 again in the reverse order of the separation method of the traction member 30-2.

[0110] Such a structure has the advantage that, when the traction force when initially attaching the wound stapler to the wound site needs to be adjusted according to actual needs, there is no need to remove the attached wound stapler and then re-attach it. Instead, the length of the traction member 30-2 can be easily adjusted in the already attached wound stapler in the manner described above.

[0111] In addition, as described above, in the existing prior patents, there is a structural feature of lifting the traction member 30-2 upward and separating it from the guiding member 30-5 in order to readjust the length of the traction member 30-2. In this case, there is a problem that scars may occur in the future because it causes pain at the wound site and uneven height at the wound site during the process of readjusting the length of the traction member 30-2. In the case of the present invention, it is characterized in that it includes a structural feature of pulling the traction member 30-2 laterally to separate it from the guiding member 30-5.

[0112] Therefore, compared with the wound stapler disclosed in the existing prior patents, it has the advantages of minimizing the pain caused during readjustment of the length, and also minimizing the occurrence of scars because it can evenly maintain the height of the skin at the wound site.

[0113] Preferably, when referring to Figure 3 the fixing part 30-1 including the traction member fitting part 30-4 and the guiding member 30-5 has a "C" shape structure facing the direction opposite to the handle part 30-3, and has a structural feature of being connected at a certain interval.

[0114] With such a structure, when applied to the wound site, it acts like a joint, thus having the advantage of being able to improve the mobility of the body part where the wound site is located.

[0115] More preferably, the width of the guiding member 30-5 is 2.00 mm to 4.50 mm, the length is 4.50 mm to 5.50 mm, the width of the traction member fitting part 30-4 is 1.98 mm to 2.42 mm, the length is 4.50 mm to 5.50 mm, and the length of the fixing part 30-1 between the traction member fitting part 30-4 and the guiding member 30-5 is 1.40 mm to 1.98 mm.

[0116] When the numerical ranges of the width and length of the fixing part 30-1 including the traction member fitting part 30-4 and the guiding member 30-5 are within the above ranges, when the medical wound stapler is applied to parts such as the knee and joints that require flexibility, it has the advantage of maximizing its flexibility.

[0117] However, when deviating from the above numerical ranges, since it is not easy to ensure the desired level of flexibility, there are disadvantages such as discomfort when applied to the knee, joints, etc. or the adhesive sheet 1 detaching from the skin.

[0118] The "width" is defined as the length from one end to the other end of each corner of the guide member 30-5, the traction member fitting portion 30-4, etc., which is perpendicular to the direction of the traction member 30-2. The "length" is defined as the length from one end to the other end of each corner of the guide member 30-5, the traction member fitting portion 30-4, etc., which is parallel to the direction of the traction member 30-2.

[0119] Preferably, refer to Figure 3 When the handle portion 30 - 3 is used, the size of the handle portion 30 - 3 is preferably suitable for being held by the thumb and index finger. Specifically, the width of the handle portion 30 - 3 is preferably 15.00 mm to 20.00 mm.

[0120] Preferably, refer to Figure 3 When the traction member is attached to the guide member 30-5, the width of the fixing portion 30-1 between the traction member fitting portion 30-4 and the guide member 30-5 is 1.30 mm to 1.80 mm.

[0121] Specifically, by maintaining the spacing between the inner corners of the traction member contact portion 30-4 and the inner corners of the guide member 30-5 within the aforementioned range, the spacing between the traction members 30-2 located on the upper surface of the wound site can be maintained within the aforementioned numerical range, thereby achieving a structural feature that facilitates disinfection of the wound suture portion without requiring additional procedures or conditions. However, if the spacing deviates from the aforementioned numerical range, there is a disadvantage that it is difficult to directly disinfect the wound site while the wound suture device is in contact.

[0122] In addition, the height of the separation prevention member 30 - 52 formed on the guide member 30 - 5 is 1.50 mm to 2.50 mm.

[0123] Furthermore, each of the traction members 30 - 2 may include a plurality of locking portions 30 - 21 .

[0124] Specifically, Figure 8 A partial enlarged view of a traction member 30-2 as a structural element of the medical wound suturing device of the present invention is shown. Figure 8 The locking portion 30-21 formed on the traction member 30-2 is in the form of an equilateral trapezoidal quadrilateral in which a portion of the two side surfaces of the bottom side are vertically cut off, presenting a structural feature of an overall hexagonal shape. The characteristic of the locking portion 30-21 is that a plurality of them are formed on the traction member 30-2.

[0125] That is, by forming a plurality of locking portions 30-21 on the traction member 30-2, the user can pull the handle portions 30-3 of the two suturing units 30 left and right to a degree suitable for suturing the wound site, thereby fixing the locking portion at the desired position to the block 30-51 formed on the groove portion 30-53.

[0126] Compared to a locking portion in the shape of an equilateral trapezoidal quadrilateral, when the locking portion 30-21 is formed in the above-described shape, the user can utilize the force transmitted during the process of pulling the handle portion 30-3 to easily allow the traction member 30-2 to pass over the locking block 30-51 formed in the groove portion 30-53 of the guide member 30-5, thereby making it easier to adjust the length. Furthermore, when the user positions the locking portion 30-21 at the desired position of the locking block 30-51, the locking portion 30-21 can be firmly fixed to the locking block 30-51 unless additional force is applied.

[0127] However, when the locking portion 30-21 is formed into an equilateral trapezoidal quadrilateral shape instead of the shape described above, the user needs to use greater force to pull the handle portion 30-3 in order to overcome the locking block 30-51, which has the disadvantage that the force or vibration may be transmitted to the wound area and cause pain in the wound area.

[0128] Preferably, a ratio H / D of the height of each locking portion 30 - 21 to the spacing distance between the plurality of locking portions 30 - 21 is 1 to 10, more specifically 2 to 5, and in further detail 2.3.

[0129] When the ratio of the height of each locking portion 30-21 to the spacing between the multiple locking portions 30-21 is maintained within the aforementioned range, vibration or shock generated when the traction member 30-2 is pulled to close the wounded skin area can be reduced, thereby minimizing pain in the wound area. Furthermore, the traction member 30-2 is stably restrained to the locking block 30-51, exhibiting excellent fixing force. Furthermore, when the traction member 30-2 is separated laterally to adjust its length, it can be easily separated without applying significant force.

[0130] However, in the case where the value is larger than or smaller than the range, pain may be caused during adjustment of the traction member 30 - 2 , or the fixing force of the locking portion 30 - 21 may be slightly reduced.

[0131] Preferably, a ratio B / A of the wide width to the narrow width of the locking portion 30 - 21 is 1 to 3, more specifically 1.5 to 2, and in further detail 1.68.

[0132] Within this range, the advantages of not only providing a strong fixing force of the locking portion 30-21 but also minimizing pain at the wound site caused by pulling the traction member 30-2 are achieved. On the other hand, if the length of the traction member 30-2 is adjusted beyond this range, the user may experience increased vibration or shock when adjusting the length of the traction member 30-2, potentially causing pain. If the length of the traction member 30-2 is adjusted below this range, the fixing force of the locking portion 30-21 may be reduced.

[0133] The medical wound suturing device suturing a wound is performed by pulling the handle portion 30 - 3 in each suturing unit 30 left and right.

[0134] Figure 10 FIG. 1 shows a diagram of a medical wound suturing device in use according to an embodiment of the present invention. Figure 10 After attaching the first adhesive sheet 10 and the second adhesive sheet 20 to the skin on both sides based on the wound site, hold the handle 30-3 in each of the two suturing units 30 and pull it to the left or right to suture the wound.

[0135] Specifically, its structure is as follows: when the handle portion 30-3 is pulled left or right to the extent that the wound area can be sutured, the locking portion 30-21 formed on each traction member 30-2 is locked to the locking blocks 30-51a and 30-51b formed inside the guide member 30-5 and fixed, thereby keeping the wound areas in a state of interlocking with each other for a long time, so that the wound areas can be sutured, and the guide member 30-5 is for the traction member 30-2 to pass through.

[0136] Furthermore, after the wound stapler of the present invention is bonded to the wound and the handle 30-3 is pulled leftward or rightward to secure the wound, the handle 30-3 can be cut off. This provides the advantage of making daily activities more convenient while the wound stapler is attached. The cut-off portion of the handle 30-3 can be any portion of the traction member 30-2 region between the handle 30-3 and the guide member 30-5, preferably adjacent to the guide member 30-5, but is not limited thereto.

[0137] In addition, when the length of the traction member 30-2 needs to be adjusted again as time passes after the wound occurs, the traction member 30-2 is pulled toward the open side of the groove portion 30-53 to artificially separate the traction member 30-2 from the guide member 30-5 through the side of the guide member 30-5. The traction member 30-2 can then be additionally pulled or pushed to the left or right to the required length, and the traction member 30-2 can be again connected and fixed to the groove portion 30-53 of the guide member 30-5 in the reverse order of the separation method of the traction member 30-2.

[0138] That is, its advantage is that when the traction force when the wound stapler is initially attached to the wound site needs to be adjusted according to actual needs, there is no need to remove the already attached wound stapler and then re-attach it. Instead, the length of the traction member 30-2 can be easily adjusted in the already attached wound stapler in the manner described above.

[0139] Furthermore, in order to adjust the traction force, the prior patents, unlike the present invention, lift the traction member 30-2 upward from the guide member 30-5 and separate it, and then adjust the length again. In the process of applying the upward lifting force, the height of the skin at the wound site may become uneven, thereby posing the problem of causing scars later.

[0140] In contrast, when the present invention adopts a method of separating the traction member 30 - 2 by the side surface of the guide member 30 - 5 , there is an advantage that the problems existing in the prior art can be improved.

[0141] In addition, the pair of adhesive sheets 1 may have a porous structure that can be sterilized.

[0142] Furthermore, the medical wound suture device includes an adhesive layer and a protective sheet layer located below each adhesive sheet 1 . The protective sheet layer may include an extension portion extending toward the outside of the adhesive sheet 1 .

[0143] The pair of adhesive sheets 1 are formed in the form of sheets with a predetermined area so that they can be attached to both sides of the wound site. An adhesive layer can be formed on the lower surface of the adhesive sheet. In addition, a protective sheet layer can be formed below the adhesive layer to protect the adhesive layer. When in use, the protective sheet layer is removed and the wound is attached to the skin.

[0144] The pair of adhesive sheets 1 are medical sheets that need to be firmly attached to the skin along the curved surface of the human body without warping. Therefore, they can be made of a stretchable elastic material (for example, a soft synthetic resin material). At the same time, the pair of adhesive sheets 1 can be sterilized and can be a porous structure with multiple fine through-holes for ventilation. As an example, the adhesive sheet 1 can be made of a hydrophilic colloid patch with a polyurethane film used as a medical moist patch, but it is not limited to this. As long as the material can be used as a medical moist patch by ordinary technicians in this field, there is no special limitation.

[0145] Furthermore, the adhesive layer is coated with a known substance used as a medical adhesive, preferably a hydrocolloid, but is not limited thereto. As long as the material can be used as a medical adhesive by ordinary technicians in this field, there is no particular limitation.

[0146] In addition, the protection sheet layer includes an extension portion extending toward the outside of the adhesive sheet 1 . When the extension portion is formed on the protection sheet layer, it is advantageous in that the protection sheet layer can be easily removed.

[0147] The protective sheet layer may be made of a polyurethane film, but is not limited thereto. As long as the material can be used as the protective sheet layer by a person skilled in the art, there is no particular limitation.

[0148] In addition, the material of the various components of the wound stapling device of the present invention, such as the fixing portion 30-1, the pulling member 30-2, the handle portion 30-3, the guide member 30-5, the pulling member contact portion 30-4, the locking portion 30-21, the blocking block 30-51, and the anti-detachment member 30-52, is preferably a flexible resin such as polyethylene, polypropylene, or polyurethane, but is not limited to this. As long as the flexible material can be used as the material of the various components by ordinary technicians in this field, there are no particular restrictions.

[0149] In addition, refer to Figure 9 Not only can the width and length of a pair of adhesive sheets 1 be appropriately selected according to the size of the wound area, but the number of suturing units 30 on the adhesive sheet 1 can also be appropriately selected according to the size of the wound area. For this reason, the medical wound suturing device according to the present invention can be prepared and provided according to various specifications.

[0150] Although the present invention has been described with reference to preferred embodiments thereof, persons skilled in the art or persons of ordinary skill in the art may make various modifications and variations to the present invention without departing from the technical concept and technical scope of the present invention as set forth in the appended claims. Therefore, the technical scope of the present invention is not limited to the specific embodiments described in the specification, but is defined by the appended claims.
