Abstract
Description
Technical Field
[0001] The utility model relates to the medical field, in particular to a fascia suturing tool. Background Art
[0002] Existing medical surgical operations have shifted from traditional large-area wound surgery to minimally invasive small incision surgery. Compared with traditional open surgery, minimally invasive surgery has the advantages of reducing patient pain, reducing the risk of wound infection, shortening postoperative recovery time, reducing scars and saving costs. Among them, endoscopic surgery is more widely used.
[0003] The surgical wounds produced during endoscopic surgery are generally sutured after the operation. In order to avoid scars at the sutured wounds in the future, the fascia and fascia layer under the cortex are usually sutured.
[0004] However, since the fascia layer is located deep inside the skin, the opening of the minimally invasive surgical wound is small, and the space available for the suture needle to move and the field of view when moving the needle are small, making it inconvenient to insert the needle for suturing, resulting in unsatisfactory suturing effects or errors. Not only will it consume a lot of time and energy of medical staff, prolonging the operation time, but the unsatisfactory sutures are not conducive to the patient's postoperative recovery.
[0005] Therefore, a suturing tool that can conveniently and efficiently pass a suture thread into and out of the subcutaneous cervical membrane is needed. Utility Model Content
[0006] The utility model aims to provide a fascia suturing tool, which can guide the suture and pass through the subcutaneous fascia on both sides of the wound, and the operation process is convenient and efficient.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A fascia suturing tool comprises a first clamp body, a second clamp body, a control handle and a guide wire, wherein the control handle comprises a first grip and a second grip, the first grip is connected to the first clamp body, the second clamp body is connected to the second grip, and the first clamp body and the second clamp body are hinged to each other, the end of the first clamp body away from the first grip and the end of the second clamp body away from the second grip are both puncture parts, the first clamp body is provided with a first channel for the guide wire to pass through, and the second clamp body is provided with a second channel for the guide wire to pass through, when the first clamp body and the second clamp body are buckled with each other, the guide wire can drive the existing suture thread to pass through the first channel and the second channel in sequence, and the guide wire drives the suture thread to pass through the side of the second clamp body close to the control handle.
[0009] Compared with the prior art, the fascia suturing tool using the above technical solution has the following beneficial effects:
[0010] The fascia suturing tool of the utility model is adopted to control the opening and closing of the first grip and the second grip to control the opening and closing range of the first clamp body and the second clamp body, and cooperate with the special structure of the puncture part to respectively pierce the subcutaneous fascia on both sides of the surgical wound, and then control the first clamp body and the second clamp body to achieve the purpose of connecting the first channel and the second channel.
[0011] After the suture is introduced into the first channel and the second channel at the same time by using the guide wire, since the suture and the suture tool are relatively independent, when the guide wire, the first clamp body and the second clamp body are withdrawn in sequence, most of the suture can be left in the subcutaneous fascia on both sides at the same time, and the corresponding suturing operation can be performed later. In this way, there is no need to insert the suture needle into the wound, thereby avoiding the existing inconvenience of needle movement, thereby effectively improving the surgical efficiency of medical staff, shortening the operation time, and facilitating the healing and recovery of the wound.
[0012] Preferably, the puncture portion of the first clamp body and the puncture portion of the second clamp body are both arc-shaped structures, and when the first clamp body and the second clamp body are engaged with each other, the first channel and the second channel are smoothly transitioned and connected. By utilizing the smooth characteristics of the arc-shaped structure, during the process of the guide wire driving the suture thread to penetrate, the guide wire smoothly enters the second channel from the first channel, effectively improving the smoothness of the guide wire guiding operation and the efficiency of the suturing work.
[0013] Preferably, the puncture part is provided with an oblique groove, and the first clamp body and the second clamp body are buckled so that the oblique grooves of the two puncture parts fit each other. The oblique groove can effectively reduce the area of the puncture point of the puncture part, thereby making the force point more concentrated, effectively increasing the puncture effect, and further reducing the time spent on suturing; and because the slopes of the two puncture parts correspond to each other, the normal docking of the first channel and the second channel is not affected.
[0014] Preferably, the end of the guide wire is provided with a winding groove or a clamping groove for the suture to be inserted. The winding groove or the clamping groove can be used to temporarily fix the guide wire insertion end and the suture, thereby achieving the purpose of the guide wire driving the suture. This structure will not be easily separated during the guiding process, and it is convenient to separate the suture and the guide wire after subsequent penetration.
[0015] Preferably, a damping layer is provided at the hinge of the first and second jaw bodies, and angle prompt marks are provided at the hinge of the first and second jaw bodies and on the surfaces of the first and second grips. The deceleration and buffering effect of the damping layer is utilized to limit the opening and closing range of the first and second jaw bodies, thereby avoiding random movement during the insertion process and increasing the smoothness of suture insertion; the angle prompt mark facilitates quick identification of the insertion angle, and when used in conjunction with the damping layer, the problem of excessive opening and closing can be further avoided. In combination with the pre-calculation of the wound size before surgery, the suture tool can be directly opened to a specific angle during the suturing process, further improving surgical efficiency.
[0016] Preferably, the first handle and / or the second handle are provided with a winding block for fixing the end of the suture. The winding block and part of the suture are used for temporary fixation to control the end of the suture outside the surgical wound, which is convenient for direct suturing when the suturing tool is withdrawn later.
[0017] Preferably, a locking structure for limiting the movable state is provided between the first handle and the second handle. By locking the positions of the first handle and the second handle, the first clamp body and the second clamp body are limited to the state inside the wound, thereby avoiding the stability of accidental movement during the suture insertion process and ensuring the safety and smoothness of the insertion process.
[0018] Preferably, the locking structure includes a first convex tooth portion and a second convex tooth portion, the first convex tooth portion is arranged on the first grip side wall, the second convex tooth portion is arranged on the second grip side wall, the first convex tooth portion and the second convex tooth portion are both provided with a plurality of inclined convex teeth made of elastic material, and the first convex tooth portion and the second convex tooth portion are arranged in opposite directions. By utilizing the elastic properties of the elastic material, the first convex tooth portion and the second convex tooth portion can be docked and locked when the first grip and the second grip are close to each other, and this state is synchronized with the first clamp body and the second inlay inside the wound, so the locking is convenient and easy to operate directly.

DETAILED DESCRIPTION
[0033] The utility model is further described below in conjunction with the accompanying drawings.
[0034] like Figures 1 to 13 The fascia suturing tool shown includes a first clamp body 1 , a second clamp body 2 , a control handle and a guide wire 4 .
[0035] The control handle includes a first grip 30 and a second grip 31 . The first grip 30 is connected to the first pliers body 1 , the second pliers body 2 is connected to the second grip 31 , and the first pliers body 1 and the second pliers body 2 are hinged to each other.
[0036] The first clamp body 1 is provided with a first channel 10 for the guide wire 4 to pass through, and the second clamp body 2 is provided with a second channel 20 for the guide wire 4 to pass through. When the first clamp body 1 and the second clamp body 2 are buckled together, the guide wire 4 can drive the existing suture thread 0 to pass through the first channel 10 and the second channel 20 in sequence, and the guide wire 4 drives the suture thread 0 to pass out from the side of the second clamp body 2 close to the control handle.
[0037] In order to bring the suture thread 0 into the incision edge on the inner side of the skin tissue (the fascia under the skin), the first clamp body 1 and the second clamp body 2 themselves have a certain puncture property, that is, the end of the first clamp body 1 away from the first handle 30 and the end of the second clamp body 2 away from the second handle 31 are both puncture parts 5.
[0038] In the process of the guide wire 4 passing from the first channel 10 to the second channel 20, in order to increase the smoothness of the operation process and avoid excessive damage to the first clamp body 1 and the second clamp body 2 when they are inserted, in this embodiment, the puncture portion 5 of the first clamp body 1 and the puncture portion 5 of the second clamp body 2 are both arc-shaped structures, and the first clamp body 1 and the second clamp body 2 themselves also have a certain curvature, that is, when the first clamp body 1 and the second clamp body 2 are buckled together, the first channel 10 and the second channel 20 are smoothly transitioned and connected.
[0039] While satisfying the first channel 10 and the second channel 20, in order to ensure the puncture effect of the puncture part 5, the puncture part 5 is provided with an oblique groove 50, that is, the area of the end of the puncture part 5 is appropriately reduced to increase the smoothness of the puncture process. At the same time, the oblique groove 50 structure can satisfy the normal docking of the first channel 10 and the second channel 20, that is, the first clamp body 1 and the second clamp body 2 are buckled together to make the oblique grooves 50 of the two puncture parts 5 fit each other.
[0040] In order to achieve the purpose of the guide wire 4 driving the suture 0, the end of the guide wire 4 is provided with a winding groove 40 or a clamping groove for the suture 0 to be embedded. In this embodiment, the winding groove 40 is selected to facilitate the subsequent rapid separation of the guide wire 4 and the suture 0.
[0041] In order to avoid the accident that the suture 0 is pulled off when the guide wire 4 is subsequently withdrawn, the fascia suturing tool is also provided with a winding block 7 for fixing the end of the suture 0. The winding block 7 can be set on the surface of the first handle 30, and the winding block 7 can also be set on the surface of the second handle 31. When it is set on the surface of the first handle 30 or the second handle 31, one end of the suture 0 can be fixed. The winding block 7 can also be set on the surfaces of the first handle 30 and the second handle 31 at the same time, so as to fix both ends of the suture 0. The figure of this embodiment selects the solution in which the winding block 7 is set on the surface of the second handle 31.
[0042] In order to avoid the problem of excessive adjustment of the first pliers body 1 and the second pliers body 2 during the insertion and use of the first pliers body 1 and the second pliers body 2, and to facilitate quick clarification of the insertion angle, a damping layer made of silicone or rubber is provided at the hinge of the first pliers body 1 and the second pliers body 2, and angle prompt marks 6 are provided on the hinge of the first pliers body 1 and the second pliers body 2 and on the surface of the first handle 30 and the second handle 31.
[0043] In addition, during the process of inserting the suture 0 , in order to stably maintain the connection state between the first channel 10 and the second channel 20 , a locking structure for limiting the movable state is provided between the first handle 30 and the second handle 31 .
[0044] Regarding the locking structure between the first handle 30 and the second handle 31, it can be locked by adsorption, buckling or by an external strap. In the present embodiment, the locking structure includes a first convex tooth portion 8 and a second convex tooth portion 9. The first convex tooth portion 8 is arranged on the side wall of the first handle 30, and the second convex tooth portion 9 is arranged on the second gripping side wall. The first convex tooth portion 8 and the second convex tooth portion 9 are both provided with a plurality of inclined convex teeth made of elastic silicone or rubber, and the first convex tooth portion 8 and the second convex tooth portion 9 are arranged in relative directions.
[0045] The following is the usage of this embodiment:
[0046] First, Figure 7 As shown, by controlling the opening and closing of the first grip 30 and the second grip 31, the first clamp body 1 and the second clamp body 2 are respectively passed through the subcutaneous fascia on both sides of the surgical wound using the puncture portion 5. During this process, the insertion angle can be determined by the angle prompt mark 6; and as shown in FIG. Figure 8 The puncture portion 5 of the first clamp body 1 and the puncture portion 5 of the second clamp body 2 are controlled to be engaged with each other, and the first convex tooth portion 8 and the second convex tooth portion 9 are mutually engaged, so as to achieve the locking of the first handle 30 and the second handle 31.
[0047] Next, a portion of the suture thread 0 is embedded in the winding groove at the end of the guide wire 4, and the end of the suture thread 0 away from the guide wire 4 is wound around the winding block of the second handle 31, as shown in FIG. Fig. 9 As shown in FIG. 1 , the end of the guide wire 4 with the wire winding groove is inserted into the first channel 10 of the first clamp body 1, as shown in FIG. Fig.10 As shown, the guide wire 4 is pushed in continuously, so that the guide wire 4 passes through the first channel 10 and then passes into the second channel 20 until the end of the guide wire 4 with the wire winding groove passes through the surface of the second clamp body 2, thereby achieving the preliminary placement of the suture 0.
[0048] After that, pull the suture thread 0 extending from the second clamp body 2, remove this part of the suture thread 0 from the wire winding groove of the guide wire 4, and pull out this part of the suture thread 0, and pull the guide wire 4 with the other hand to make the guide wire 4 detach from the first channel 10 and the second channel 20, as shown in FIG. Fig.11 Shown is a schematic diagram of the guide wire 4 being withdrawn.
[0049] Finally, if Fig.12 As shown, the first convex tooth portion 8 and the second convex tooth portion 9 are moved to release the lock between the first grip 30 and the second grip 31, and the first inlay and the second inlay are separated. The second forceps body 2 and the first forceps body 1 are withdrawn from the surgical wound in turn by adjusting the angle, and part of the suture 0 on the wire winding block is separated. Fig.13 As shown, after the first clamp body 1 and the second clamp body 2 are separated, most of the suture thread 0 has penetrated into the subcutaneous fascia on both sides of the wound to achieve preliminary fixation, and both ends of the suture thread 0 can be directly controlled by medical staff to perform suturing operations on the inside of the wound.
[0050] The above is a preferred embodiment of the present invention. A person skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements shall also be regarded as within the protection scope of the present invention.
