Description

Technical Field

[0001] The invention relates to a wound tension-reducing suturing device and a use method thereof, belonging to the technical field of medical equipment and its application. Background Art

[0002] When the skin wound is large, medical sutures are often used to reduce the tension of the wound to promote wound healing and reduce scars. However, in the current wound suturing process, medical staff judge the tension of the wound based on the length and depth of the wound and their own experience, and then decide whether to use a tension-reducing device to help the wound heal. This method has high requirements for medical staff, and the judgment accuracy is low due to manual experience in judging the tension of the wound, and the tightness of the tension-reducing device cannot be accurately controlled. If the tightness of the tension-reducing device is low, the wound will have a greater tension risk, and the wound is prone to hypertrophic scars, and in severe cases, the wound is prone to cracking. If the tightness of the tension-reducing device is high, the wearing comfort is low, and it affects the blood circulation near the wound, thereby affecting the quality of wound healing.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1 like Figure 1-2 As shown, a wound tension-reducing suturing device comprises: A first slide 1, on which a suture thread clamping mechanism 2 and a first driving mechanism 3 connected thereto are symmetrically arranged; A tension detection device 4, which is disposed on the first carriage 1 and is used in conjunction with the suture thread clamping mechanism 2; A second slide 5, which is arranged on one side of the first slide 1, and on which a tension-reducing clamping mechanism 6 and a second driving mechanism 7 connected thereto are symmetrically arranged; The controller 8 is connected to the first driving mechanism 3 , the tension detection device 4 and the second driving mechanism 7 in an electrical circuit.

[0020] The first slide 1 comprises a rectangular frame formed by a light vertical rod and at least two horizontal rods, one of the horizontal rods is provided with a slide groove 101, and a slider 102 is symmetrically arranged in the slide groove 101, and the suture clamping mechanism 2 is slidably connected to the slide groove 101 through the slider 102. The light vertical rod and the horizontal rod are both made of plastic or aluminum rods.

[0021] The suture clamping mechanism 2 can be a manual fixed clamp structure, which is a common medical clamp on the existing market. A fixing ring can be set on the medical clamp, and the clamp is connected to the first slide 1 through the slider 102. The clamp can be manually controlled to clamp and fix the suture. Specifically, a fixing ring can be added to the jaws of the clamp. After the clamp clamps the suture, the jaws are fixed with the fixing ring to clamp the suture.

[0022] Alternatively, the suture clamping mechanism 2 is an automatic magnetic clamping structure, which includes a fixed clamping plate 201 fixedly connected to the slider 102, and a movable clamping plate 202 is provided on the bottom surface of the fixed clamping plate 201 in a position opposite thereto, and the rear end of the movable clamping plate 202 is rotatably connected to the fixed clamping plate 201 through a hinge structure 203, and the front end is magnetically connected to the fixed clamping plate 201 through a magnetic mechanism 204. The magnetic mechanism 204 is an adsorption electromagnet fixed to the front end of the fixed clamping plate, and the adsorption electromagnet is connected to the controller 8 circuit through a cable. It is designed based on the principle of battery iron attracting iron plate. After the adsorption electromagnet is energized, the movable clamping plate 202 can be attracted together with the fixed clamping plate 201 under the action of the adsorption electromagnet, and then the suture placed between the two clamps can be pressed. When the adsorption electromagnet is powered off, the movable clamping plate 202 can be opened. Then, the controller can control the fixed clamping plate 201 and the movable clamping plate 202 to clamp the suture. An anti-skid layer 205 is provided on the opposite surfaces of the fixed clamping plate 201 and the movable clamping plate 202 to prevent the suture from sliding after clamping. The anti-skid layer 205 is an anti-skid rubber soft layer, and a row of slit structures 2051 are arranged on the anti-skid rubber soft layer of the fixed clamping plate 201. The intervals of adjacent slit structures 2051 are the same or different. Specifically, the intervals of adjacent slit structures 2051 correspond to the suture spacing of the wound. In use, the sutures are first inserted into the slit structures 2051 one by one, and then the movable clamping plate 202 is sucked together with the fixed clamping plate 201 under the action of the adsorption electromagnet, so that the anti-skid rubber soft layers of the fixed clamping plate 201 and the movable clamping plate 202 can be squeezed against each other, thereby causing the slit structure 2051 to be squeezed and deformed, ensuring that the suture is clamped more securely. The hinge structure 203 includes a hinge shaft, on which a torsion spring is mounted.

[0023] The first driving mechanism 3 is any driving device such as an electric telescopic rod, a linear motor, etc., which can drive the two suture thread clamping mechanisms 2 to move closer to or away from each other.

[0024] The tension detection device 4 is a common tension detection instrument in the existing market, such as a tension meter, a pressure sensor, etc. The tension detection instrument can detect the force used to completely close the wound when the first driving mechanism 3 drives the two suture clamping mechanisms 2 to move closer to each other, that is, the tension of the wound.

[0025] The second slide 5 includes a slide bar arranged on another cross bar of the rectangular frame, and the tension-reducing clamping mechanism 6 includes a telescopic arm 601 symmetrically arranged on the slide bar. The rear ends of the two telescopic arms 601 are slidably connected to the slide bar, and the front ends are detachably connected with two semi-symmetrical arc-shaped clamping plates 602. The detachable connection structure can be a snap-on screw connection, etc.

[0026] The two half arc-shaped clamping plates 602 are provided with an elastic band fixing structure 603 for use with them. Specifically, the elastic band fixing structure 603 is an elastic Velcro adhesive tape structure or an elastic buckle band structure. The elastic buckle band structure includes an elastic band arranged at both ends of one half arc-shaped clamping plate, a plug is arranged at the end of the elastic band, and buckle seats adapted to the plug are arranged at both ends of the other half arc-shaped clamping plate, so that the two half arc-shaped clamping plates can be connected to each other through the buckle structure. Specifically, the buckle structure can be an existing buckle for backpacks. When in use, the second driving mechanism 7 drives the two telescopic arms 601 to move closer to each other, and the two semi-arc clamping plates 602 move accordingly. At the same time, the clamping force of the two semi-arc clamping plates 602 is adjusted according to the wound tension value detected by the tension detection device 4. When the clamping force of the two semi-arc clamping plates 602 is reached, the two semi-arc clamping plates can be connected to each other through the elastic band fixing structure 603, and then the connection between the telescopic arm 601 and the arc clamping plate 602 can be released. The wearing time of the arc clamping plate 602 can be considered later according to the wound healing condition.

[0027] The arc-shaped clamping plate 602 is an elastic arc-shaped plate made of resin, plastic, etc. A cushion layer is provided inside the arc-shaped clamping plate 602 to ensure wearing comfort.

[0028] The second driving mechanism 7 is any driving device such as an electric telescopic rod, a linear motor, etc., which can drive the two tension-reducing clamping mechanisms 6 to move closer to or away from each other.

The lifting mechanism 10 can be an electric telescopic rod, a cylinder structure or a cam mechanism, etc. The height of the first slide 1 can be adjusted by the support frame 9 to meet the suturing operation of wounds in different parts.

[0034] The auxiliary knotting structure 11 can be a vascular clamp commonly used in the market.

[0035] Alternatively, the auxiliary knotting structure 11 includes an adjustment frame that can be adjusted up, down, left, and right relative to the second slide 5, and a comb-tooth clamping structure is provided on the adjustment frame and is arranged parallel to the fixed clamping plate 201.

The telescopic adjustment mechanism 1107 can be an electric telescopic rod, a cylinder structure, etc.

[0037] The long strip fixed clamping plate 1101 is arranged at the bottom of the longitudinal sliding rod 1106 and is slidably connected thereto. A first long adjustment slot 1108 arranged along the length direction of the longitudinal sliding rod 1106 is provided on one side of the longitudinal sliding rod 1106. A first adjustment screw 1109 for sliding and limiting the long strip fixed clamping plate 1101 is provided in the first long adjustment slot 1108. The long strip fixed clamping plate 1101 can slide along the longitudinal sliding rod 1106 to achieve longitudinal adjustment, and can be adjusted up and down by adjusting the height of the longitudinal sliding rod 1106, and can be adjusted left and right by moving the vertical sliding rod 1105 left and right along the second slide 5. A through slot is provided along the length direction of the long strip fixed splint 1101, the movable splint 1103 is arranged in the through slot, and the adjustment teeth 1104 of the movable splint 1103 are arranged one by one in each clamping opening 1102, and a second long adjustment slot 1110 penetrating through the movable splint 1103 is provided on the top of the longitudinal sliding rod 1106, and a second adjustment screw 1111 for sliding limiting of the movable splint 1103 is provided in the second long adjustment slot 1110.

[0038] The specific operation method of the auxiliary knotting structure 11 described in this embodiment is: by operating the adjustment frame of the auxiliary knotting structure 11, the fixed splint 1101 is moved to the position just above the wound; then the fixed splint 1101 is moved downward and the clamping opening 1102 at the bottom thereof corresponds to the slipknot of each suture line one by one, and the slipknot is placed in the corresponding clamping opening 1102, and the movable splint 1103 is adjusted, and the opening of the clamping opening 1102 is adjusted by the adjustment teeth 1104 at the bottom thereof, and then the slipknot of the suture line is clamped, and the slipknot can be tied into a fixed knot. Generally, the auxiliary knotting structure 11 described in this embodiment is suitable for the case where the wound is relatively straight and the spacing between each suture line is the same, and it can complete the slipknot clamping of multiple suture lines at one time, and the operation efficiency is high.

[0039] Example 5 like Fig. 9 As shown, on the basis of Example 4, the auxiliary knotting structure 11 includes a long strip fixing seat 1112 arranged at the bottom of the longitudinal sliding rod 1106 of the adjustment frame and slidably connected thereto.

[0040] The specific operation method of the auxiliary knotting structure 11 described in this embodiment is: by operating the adjustment frame of the auxiliary knotting structure 11, the long strip fixing seat 1112 is moved to the top of the wound and as close to the wound as possible; the elastic clamping units 1113 are moved one by one to the corresponding suture slipknots, the elastic line is pulled and the spring clamp is opened to clamp the slipknot, and then the slipknot is tied into a fixed knot. Generally, the auxiliary knotting structure 11 described in this embodiment is suitable for wounds of any shape, and the spacing between each suture is different, and the application range is wide.

[0041] like Figure 10-12 As shown, the method for using the wound tension-reducing suturing device comprises the following steps: s1. Mark the suture points on both sides of the wound according to the length of the wound, pass several sutures through the corresponding suture points one by one, reserve tensioning sections at both ends of the sutures, and place them crosswise; s2. The tensioning sections at both ends of all sutures are firmly clamped by the corresponding suture clamping mechanisms 2, and the first driving mechanism 3 is used to drive the two suture clamping mechanisms 2 to move away from each other to tension the sutures, so that the wound is completely closed, and the tension after the wound is completely closed is detected by the tension detection device 4, and a first tension value is output; s3, collecting the first tension value outputted in step s2 through the controller 8, and comparing it with the tension threshold value reserved in the controller 8, to determine whether the tension-reducing clamping mechanism 6 needs to be used, No, the wound is closed by using a skin stapler 12 or manually tying sutures; Yes, the second driving mechanism 7 is used to drive the two tension-reducing clamping mechanisms 6 to move closer to each other and clamp them near the wound to reduce the tension on the wound, and then the skin suture device 12 or the manual knotting of the suture thread is used to complete the wound suturing.

[0042] In step s2, the specific use steps of the suture clamping mechanism 2 include: (2.1) The controller 8 controls the first driving mechanism 3 to drive the two suture clamping mechanisms 2 to approach the wound, and the tensioning sections reserved at both ends of the suture are placed between the fixed clamping plate 201 and the movable clamping plate 202 of the corresponding suture clamping mechanism 2. The adsorption electromagnet is energized so that the movable clamping plate 202 is attracted to the fixed clamping plate 201 under the action of the adsorption electromagnet, thereby firmly clamping the suture; Before operating the suture thread clamping mechanism 2, the height of the support frame 9 is adjusted so that the height difference between the suture thread clamping mechanism 2 and the wound position is no more than ±10 cm.

[0043] (2.2) The controller 8 controls the first driving mechanism 3 to drive the two suture clamping mechanisms 2 to move away from each other, and tension the sutures to completely close the wound. The tension after the wound is completely closed is detected by the tension detection device 4.

[0044] In step s3, the specific use steps of the tension-reducing clamping mechanism 6 include: (3.1) The controller 8 is connected to the remote control terminal by telecommunication, and a wound tension threshold database is set up at the remote control terminal. The controller 8 calls the reserved tension threshold in the wound tension threshold database and compares it with the first tension value outputted in step s2 to determine whether the tension-reducing clamping mechanism 6 needs to be used.

[0045] The wound tension threshold database is based on relevant clinical diagnosis data and experts' statistics based on wound factors, including but not limited to patient age, wound location, wound length, wound depth, etc.

[0046] (3.2) If the first tension value is less than or equal to the wound tension threshold value, there is no need to use the tension-reducing clamping mechanism 6, and the wound is sutured by using an automatic stapler 1202 or a manual knotting method; If the first tension value is greater than the wound tension threshold, the second driving mechanism 7 is used to drive the two tension-reducing clamping mechanisms 6 to move closer to each other and clamp them near the wound, and gradually apply clamping force to reduce the tension of the wound. At the same time, the tension detection device 4 detects the second tension value after the tension-reducing clamping mechanism 6 is added in real time. When the second tension value is less than or equal to the wound tension threshold, the clamping force is stopped, and the elastic band fixing structure 603 is used to fix the arc-shaped clamping plates 602 of the two tension-reducing clamping mechanisms 6, and the arc-shaped clamping plates 602 are disconnected from the telescopic arm 601; finally, the skin stapler 12 or the manual knotting of sutures is used to complete the wound suturing.

[0047] The suturing method of the skin stapler 12 is: manually operate the manual stapler to staple the sutures one by one at the same or different intervals until the wound is completely closed. Alternatively, the controller 8 controls the manipulator 1201 to automatically operate the automatic stapler 1202 to staple the sutures one by one at the same or different intervals until the wound is completely closed. Preferably, starting from one end of the wound, staples can be stapled one by one along the suture line, and then the suture line is removed to reduce skin suture damage.

[0048] The method of manually knotting the suture is as follows: after the suture passes through the suture point, it is pre-tied into a slipknot, and after the wound is stretched and closed, the auxiliary knotting structure 11 is clamped at the slipknot of the suture, and the slipknot of each suture on the entire wound is tied into a fixed knot in an interval knotting manner, and the reserved section of the suture is subtracted. Specifically, starting from one end of the wound, the odd-numbered sutures are knotted first, and then the even-numbered sutures are knotted.

[0049] In addition, wound suturing can also be performed by using suture staples in combination with suture threads. Specifically, the suture threads are passed through the suture points one by one in odd or even positions and are pre-tied into slipknots. After the wound is stretched to close, a skin suturer 12 is first used to suture the suture points where no suture threads are passed through, and then the suture threads are knotted by manually knotting the suture threads.

Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the scope of the technical solution of the present invention.
