Description

Technical Field

[0001] The invention relates to the field of surgical instruments, in particular to a minimally invasive fascia stapler used for laparoscopic surgical incisions. Background Art

[0002] With the advancement of surgical technology, it has become possible to perform surgery through smaller incisions. Laparoscopic surgery is to make several incisions with a diameter of 5 to 12 mm in the abdomen or chest, insert cameras and various special surgical instruments through these incisions, and transmit the images of various organs in the abdomen taken by the camera inserted into the abdomen to the TV screen. The surgeon observes the images and uses various surgical instruments to perform operations outside the body to complete the operation. Laparoscopic surgery has the characteristics of less trauma, fewer complications, safety, and fast recovery. Therefore, it has developed rapidly and is becoming more and more widely used. It can perform examinations and treatments at the same time. It is an advanced and cutting-edge minimally invasive technology.

[0003] After the laparoscopic surgery is completed, the incision (the passage of the laparoscope in the abdomen) still needs to be sutured. In order to avoid scarring on the skin surface at the incision or reduce the degree of scarring, there is currently a method of suturing the incision on the inside of the skin in clinical practice, that is, the surgical suture needle is passed through the incision to puncture the incision edge on the inside of the skin tissue (the fascia of the subcutaneous abdominal passage), and finally the suture line is closed and tightened, so that the suture site is located on the inside of the incision. However, since the incision is small and the site to be sutured is located relatively deep, it is difficult to provide sufficient operating space and suture field of view for the suture needle; and since it is difficult for the suture needle body to penetrate into the inside of the incision, it is difficult to control the direction and direction of the needle when suturing, resulting in great difficulty in suturing operation, prone to suturing errors or failure to meet suturing requirements, which is even more difficult for interns or doctors with insufficient suturing experience.

[0004] Therefore, how to simplify and facilitate the operation of suturing the fascia inside the incision has become an urgent problem to be solved in this technical field. Summary of the invention

[0005] The purpose of the present invention is to address the problems existing in the above-mentioned background technology and to provide a minimally invasive fascia suturing device for laparoscopic surgical incisions, which is inserted through the incision to reach the peritoneal side and performs suturing actions by operating an external operating lever, so as to puncture and suture the peritoneum, muscle, and fascia layers, thereby improving the convenience, stability, and safety of suturing.

[0006] In order to achieve the above-mentioned invention object, the present invention adopts the following technical solutions:

[0007] A minimally invasive fascia suture device for laparoscopic surgical incisions, comprising an operating rod and a suture head provided at the end of the operating rod. The suture head includes a base and at least one suture needle. The suture needle is provided with an arc-shaped needle rod for puncturing. The arc-shaped needle rod is independently arranged outside the base. The head end of the arc-shaped needle rod is provided with a needle tip, and a thread-passing hole is provided on the side of the needle tip. The tail end of the arc-shaped needle rod is fixedly connected with a support needle rod. The operating rod includes a main rod body and a control member. The main rod body is integrally fixed with the suture head. A linkage structure is arranged inside the suture head. The support needle rod and the control member are jointly connected to the linkage structure. The control member controls the swing of the support needle rod through the linkage structure, and the arc-shaped needle rod moves synchronously with the support needle rod to form a suture action.

[0008] Compared with the prior art, the minimally invasive fascia suture device for laparoscopic surgical incisions adopting the above technical scheme has the following beneficial effects:

[0009] When performing the suture operation, the suture head can be inserted through the incision, so that the suture needle extends into the suture site inside the abdominal wall. The operating rod still remains outside the incision. By only controlling the operating rod externally, the suture head can perform the suture needle action (that is, a single operation of the outer operating rod can complete the puncture actions of multiple suture openings). This reduces the requirement for the suture operation space. Since the suture head is inside the abdominal wall, it is convenient to control the orientation of the suture needle, ensuring the accuracy and success rate of the suture.

[0010] Preferably, the arc-shaped needle rod and the support needle rod are integrally formed. The end of the support needle rod away from the arc-shaped needle rod is provided with a shaft rod. The axis of the shaft rod coincides with the center of the circle of the arc-shaped needle rod. The shaft rod is connected to the linkage structure inside the base, and the linkage structure drives the shaft rod to rotate around the axis. This enables the arc-shaped needle rod to swing around its own center to form a suture action, simulating the suture operation of a doctor correctly using a round needle and avoiding damage to the skin tissue caused by lateral pulling due to the deviation of the arc-shaped needle rod.

[0011] Preferably, the linkage structure includes a worm, a transmission gear, and a driven gear. The control member includes a rotating rod. The rotating rod is sleeved in the main rod body and is coaxially and rotatably connected to the main rod body. The end of the rotating rod is fixedly connected to the worm to control the rotation of the worm. The axis of the transmission gear is perpendicular to the axis of the worm, and the transmission gear is meshed with the worm. The driven gear is meshed with the transmission gear. The support needle rod penetrates into the base and is fixedly connected to the driven gear. Using the transmission gear for transmission enables the driven gear connected to the support needle rod to form an indirect linkage relationship with the worm, allowing the suture needle to have sufficient swing space in a smaller suture head and avoiding the suture needle hitting the worm when swinging upward or back.

[0012] Preferably, the base is provided with a thread-hooking groove. The needle tip can be turned upwards and inserted into the thread-hooking groove. The inner wall of the thread-hooking groove is provided with a fixed hook. The side of the fixed hook facing the outside of the thread-hooking groove is an arc-shaped slope. The side wall of the needle tip is provided with a thread-dropping groove. The thread-dropping groove extends from the needle tip towards the arc-shaped needle bar. The thread-passing hole penetrates the thread-dropping groove laterally. When the needle tip is inserted into the thread-hooking groove, the fixed hook is embedded in the thread-dropping groove. When performing suturing, after the suture needle with thread penetrates the skin tissue, its needle tip enters the thread-hooking groove. At this time, swinging the suture needle back can automatically hook out the suture thread. Pulling out the suture needle head can bring out the suture thread that has passed through the inner skin tissue, so as to perform subsequent closing and tying operations, without the need to separately use tools such as tweezers to clamp out the suture thread, making the suturing operation simpler.

[0013] Preferably, the base is provided with a needle-receiving groove. The needle-receiving groove is formed by being recessed from the surface of the base. The suture needle is arranged in the needle-receiving groove and the height of the side surface of the suture needle does not exceed the surface of the base. The upper and lower opposite side walls of the needle-receiving groove respectively form a rotation-limiting table surface and a fitting table surface. The fitting table surface is arc-shaped and concentric with the arc-shaped needle bar. When the suture needle is turned downwards until the supporting needle bar contacts the rotation-limiting table surface to prevent the suture needle from continuing to turn downwards, at the same time, the arc-shaped needle bar fits to the fitting table surface. During the process of inserting or pulling out the suture head into or from the incision, the suture needle can be received in the needle-receiving groove, avoiding the needle tip or the needle bar exceeding the surface of the suture head, thereby avoiding the needle tip from scratching the skin tissue and ensuring the smooth insertion and extraction of the suture head in the incision.

[0014] Preferably, the suture head includes at least one suture needle group. The suture needle group includes two suture needles. The two suture needles in the same suture needle group are symmetrically arranged with respect to the central plane of the base, and the two suture needles in the same suture needle group are simultaneously connected to a linkage structure. The linkage structure drives the two suture needles in the same suture needle group to move symmetrically synchronously. When suturing, the two symmetric suture needles can respectively and simultaneously penetrate the skin tissues on both sides of the incision, having the advantages of faster suturing speed and more precise and neater sutures on both sides of the incision compared with the traditional suturing method (threading the two sides in sequence).

[0015] Preferably, the suture head is provided with two suture needle groups. The two suture needle groups are arranged side by side on the base. One needle-receiving groove is respectively provided on the outer walls on both sides of the base. Two needle-receiving channels are provided inside the base. The needle-receiving channels extend inwards from the ends of the base. The two needle-receiving channels are respectively arranged close to the two needle-receiving grooves and are separated from the two needle-receiving grooves by thin partitions respectively. The two needle-receiving channels are separated by a thick partition. The two suture needles in the same suture needle group are respectively arranged in the adjacent needle-receiving groove and needle-receiving channel. The design of using two suture needle groups can not only avoid increasing the volume of the suture head and the overly complex cooperation between the suture needle and the linkage structure, but also can perform two side-by-side threading operations simultaneously, improving the neatness of suturing and the suturing speed.

[0016] Preferably, the support needle bar is arranged along the radial direction of the arc-shaped needle bar, and the arc-shaped needle bar and the support needle bar form a V-shaped angle, and the central angle of the sector formed by the arc-shaped needle bar and its center does not exceed 90°.

[0017] Preferably, an easily breakable rod is provided at the bottom of the fixing hook, and the fixing hook is connected to the inner wall of the hook-shaped groove through the easily breakable rod. When the fixing hook hooks the suture, pulling the suture outwards causes the easily breakable rod to be subjected to a lateral pulling force until the easily breakable rod breaks, and the suture together with the fixing hook disengages from the hook-shaped groove.

[0018] Preferably, the fixing hook is provided with a clamping seam for the suture to be embedded, and the clamping seam extends from the concave side of the fixing hook to the middle of the fixing hook, and the entrance of the clamping seam is located at the deepest depression on the concave side of the fixing hook.

[0019] After the suture needle is pulled out after suturing, only need to pull the suture forcefully to give the fixing hook a relatively large outward pulling force until the easily breakable rod breaks, then the suture can be taken out smoothly; in the preferred solution, pulling the suture forcefully can make the suture slide into and be clamped and fixed in the clamping seam. When the easily breakable rod breaks, the fixing hook can be hung on the suture and taken out together with the suture, avoiding the fixing hook falling off, which is not conducive to recycling, and especially avoiding the fixing hook falling into the patient's incision.

Detailed implementation manners

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] As Figures 1 to 10 shown, the minimally invasive fascia suture device for laparoscopic surgical incisions includes an operating rod 1 and a suture head 2 provided at the end of the operating rod 1. The suture head 2 includes a base 20 and two suture needle groups. The two suture needle groups are arranged side by side on the base 20. Each suture needle group includes two suture needles 21. The two suture needles 21 in the same suture needle group are symmetrically arranged with respect to the central plane of the base 20. The suture needle 21 is provided with an arc-shaped needle rod 210 for puncturing. The arc-shaped needle rod 210 is independently provided outside the base 20. The head end of the arc-shaped needle rod 210 is provided with a needle tip 213. A thread-passing hole 214 is provided on the side of the needle tip 213. The tail end of the arc-shaped needle rod 210 is fixedly connected with a support needle rod 211. The arc-shaped needle rod 210 and the support needle rod 211 are integrally formed. The end of the support needle rod 211 away from the arc-shaped needle rod 210 is provided with a shaft rod 212. The axis of the shaft rod 212 coincides with the center of the circle of the arc-shaped needle rod 210. The support needle rod 211 is arranged along the radial direction of the arc-shaped needle rod 210. The arc-shaped needle rod 210 and the support needle rod 211 form a V-shaped included angle. The central angle of the sector formed by the arc-shaped needle rod 210 and its center of the circle is 90°.

[0031] The operating rod 1 includes a main rod body 10 and a control member 11. The main rod body 10 is integrally fixed to the suture head 2. The control member 11 is a rotating rod, which is sleeved in the main rod body 10 and is coaxially and rotatably connected to the main rod body 10. A linkage structure 22 is provided inside the suture head 2. The linkage structure 22 includes a worm 220, two transmission gears 221 and two driven gears 222. The rotating rod extends from inside the main rod body 10 into the base 20 and is fixedly connected to the worm 220 to control the rotation of the worm 220. The axes of the transmission gears 221 are perpendicular to the axis of the worm 220. The two transmission gears 221 are respectively arranged on both sides of the worm 220 and are simultaneously meshed with the worm 220. The two driven gears 222 are respectively arranged below the two transmission gears 221 and are meshed with the transmission gears 221. The shafts 212 of the two suture needles 21 penetrate into the base 20 and are respectively fixedly connected to the two driven gears 222. By rotating the rotating rod, the transmission gears 221 are rotated, and then the driven gears 222 are driven to rotate. The driven gears 222 drive the shafts 212 to rotate around the axis, so that the two suture needles 21 in the same suture needle group move synchronously and symmetrically. When suturing, the two symmetrical suture needles 21 can respectively and simultaneously penetrate the skin tissues on both sides of the incision to form a suturing action.

[0032] A needle receiving groove 23 is respectively provided on the outer walls of both sides of the base 20, and two needle receiving channels 24 are provided inside the base 20. Among them, the needle receiving groove 23 is formed by a depression on the surface of the base 20. The suture needle 21 is arranged in the needle receiving groove 23 and the height of the side surface of the suture needle 21 does not exceed the surface of the base 20. The upper and lower opposite side walls of the needle receiving groove 23 respectively form a rotation limiting table surface 230 and a fitting table surface 231. The fitting table surface 231 is arc-shaped and has the same center of the circle as the arc-shaped needle rod 210. The suture needle 21 is turned downward until the support needle rod 211 contacts the rotation limiting table surface 230 to prevent the suture needle 21 from further turning downward. At the same time, the arc-shaped needle rod 210 fits to the fitting table surface 231. During the process of inserting or pulling out the suture head 2 from the incision, the suture needle 21 can be received in the needle receiving groove 23 to avoid the needle tip 213 or the needle rod exceeding the surface of the suture head 2. The needle receiving channels 24 extend inward from the end of the base 20. The two needle receiving channels 24 are respectively arranged close to the two needle receiving grooves 23 and are separated from the two needle receiving grooves 23 by thin partitions respectively. The two needle receiving channels 24 are separated by a thick partition. The two suture needles 21 in the same suture needle group are respectively arranged in the adjacent needle receiving groove 23 and needle receiving channel 24.

[0033] The base 20 is provided with a thread-hooking groove 25. Each suture needle 21 is correspondingly provided with a thread-hooking groove 25. The tip 213 of the needle can be turned upwards and inserted into the thread-hooking groove 25. The inner wall of the thread-hooking groove 25 is provided with a fixing hook 26. The side of the fixing hook 26 facing the outside of the thread-hooking groove 25 is an arc-shaped slope 260. The side wall of the tip 213 is provided with a thread-releasing groove 215. The thread-releasing groove 215 extends from the tip 213 towards the arc-shaped needle bar 210. The threading hole 214 penetrates the thread-releasing groove 215 laterally. When the tip 213 is inserted into the thread-hooking groove 25, the fixing hook 26 is embedded into the thread-releasing groove 215. Continuing to push the suture needle 21 inwards can make the suture thread 3 slide over the arc-shaped slope 260 of the fixing hook 26 and enter the concave side of the fixing hook 26, so that the suture thread 3 is hooked. At this time, swinging the suture needle 21 back can automatically hook out the suture thread 3. Pulling out the suture needle head can bring out the suture thread 3 that has passed through the inner skin tissue, so as to perform subsequent operations of gathering and tightening the suture thread 3.

[0034] The bottom of the fixing hook 26 is provided with an easily breakable rod 27. The fixing hook 26 is connected to the inner wall of the thread-hooking groove 25 through the easily breakable rod 27. The easily breakable rod 27 is made of a material or structure that is easily broken when subjected to a large pulling force. The fixing hook 26 is provided with a clamping groove 261 for the suture thread 3 to be embedded. The clamping groove 261 extends from the concave side of the fixing hook 26 to the middle of the fixing hook 26. The entrance of the clamping groove 261 is located at the deepest depression of the concave side of the fixing hook 26. After pulling out the suture needle head after suturing, pulling the suture thread 3 forcefully gives the fixing hook 26 a large lateral pulling force until the easily breakable rod 27 breaks. When pulling the suture thread 3 forcefully, the suture thread 3 will slide into and be clamped and fixed in the clamping groove 261. When the easily breakable rod 27 breaks, the fixing hook 26 can be hung on the suture thread 3 and taken out together with the suture thread 3 to avoid the fixing hook 26 falling off.

[0035] When performing the suturing operation, insert the suture head 2 through the incision, so that the suture needle 21 extends into the part to be sutured inside the skin tissue, while the operating rod 1 still remains outside the incision. Only by controlling the operating rod 1 externally can the suture head 2 perform the suture needle action, reducing the requirement for the suture operation space. Since the suture needle head is inside the incision, it is convenient to control the orientation of the suture needle 21 and ensure the accuracy and success rate of suturing.

[0036] The above is the preferred embodiment of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, several variations and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
