Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable meniscus double-needle suturing device. Background Art

[0002] In the medical field, especially in orthopedic surgery, the repair surgery of the posterior horn tear of the meniscus usually uses a double needle for suturing. This double needle is a suture with two longer and softer needles at both ends. When suturing, a cannula is usually used to penetrate from the outside of the skin, and the top of the cannula is aligned with the part to be sutured. The suture needle is then inserted from the inner hole of the cannula and passes through the cannula to reach the part to be sutured. In this operation, an assistant assists in using an arthroscope so that the doctor can see the situation inside the joint cavity through the arthroscope, so that the doctor can perform the suturing operation.

[0003] The double-needle pushers currently available on the market generally require two people to work together during the repair surgery of the posterior horn tear of the meniscus. The assistant needs to hold the arthroscope, while the doctor needs to hold the cannula with one hand and push the needle with the other hand. The doctor and the assistant need to cooperate tacitly. For this reason, we propose a disposable meniscus double-needle suture device. Utility Model Content

[0004] The utility model aims to provide a disposable meniscus double-needle suture device to solve the problems raised in the above-mentioned background technology.

[0024] like Figure 1-5 As shown, a technical solution provided by the utility model:

[0025] A disposable meniscus double-needle suture device comprises a handle 1, wherein a first metal tube 2 and a second metal tube 3 are respectively arranged at the two inner ends of the handle 1, a first suture needle 4 and a second suture needle 5 are movably sleeved between the inner ends of the first metal tube 2 and the second metal tube 3, and a suture thread 6 is connected to the same-direction ends of the first suture needle 4 and the second suture needle 5; a direct-push mechanism 7 is arranged on both sides of the end of the handle 1 close to the first metal tube 2, the direct-push mechanism 7 comprises an axis frame 701, a rotating disk 702 and a rotating shaft 703, through-grooves 8 are penetrated at both ends of the middle part of the handle 1, and the ends of the suture thread 6 away from the first suture needle 4 and the second suture needle 5 pass through the through-grooves 8 and are respectively wound around the outside of the rotating shafts 703 at both ends; the outer ends of the two ends of the side of the handle 1 close to the first metal tube 2 are fixedly connected to the axis frame 701, the middle parts of the two axis frames 701 are movably sleeved to the rotating shaft 703, and the outer middle part of the rotating shaft 703 is fixedly connected to the rotating disk 702;

[0026] In this embodiment, when in use, the first metal tube 2 is inserted into the wound of human tissue until the end of the first metal tube 2 is against the part that needs to be sutured, and then any one of the turntables 702 is rotated. When the turntable 702 rotates, the suture thread 6 is wound and rolled up through the rotating shaft 703. The suture thread 6 will make one of the first suture needle 4 or the second suture needle 5 connected to it protrude from the end of the first metal tube 2, and then use a tool to pull out the protruding first suture needle 4 or the second suture needle 5, and then rotate the other turntable 702 and operate in the same way. When the first suture needle 4 and the second suture needle 5 are all pulled out, the suture thread 6 wrapped on the two turntables 702 is removed, and then the first suture needle 4 and the second suture needle 5 are clamped at the same time and continuously pulled out until the suture thread 6 is far from one end of the first suture needle 4 and the second suture needle 5 and is knotted at the position where suture is needed. In this way, it can be operated by one person, and the operation method is more convenient.

[0027] like Figure 4 As shown, both ends of the rotating shaft 703 are provided with openings 9 inwardly, and the outer walls of both sides of the rotating shaft 703 at the openings 9 at both ends are provided with side grooves 10, and the ends of the suture thread 6 away from the first suture needle 4 and the second suture needle 5 pass through the openings 9 and are wound in the side grooves 10 on both sides;

[0028] In this embodiment, openings 9 are provided at both ends of the rotating shaft 703. When winding the suture 6, the suture 6 is first inserted into the opening 9 and then wound and fixed along the side grooves 10 on both sides. This can prevent the suture 6 from slipping and facilitate the winding of the suture 6 on the rotating turntable 702.

[0029] like Figure 2 As shown, a plurality of tube grooves 11 are provided on the inner walls of both sides of the middle of the handle 1, and the ends of the first metal tube 2 and the second metal tube 3 close to the handle 1 are respectively clamped and fixed to the tube grooves 11;

[0030] In this embodiment, the first metal tube 2 and the second metal tube 3 are bonded and fixed to the tube groove 11 , which can improve the structural stability.

[0031] like Figure 4 As shown, a plurality of anti-slip grooves 12 are provided at the outer wall of the turntable 702 with equal arcs;

[0032] In this embodiment, an anti-skid groove 12 is provided inwardly on the outer wall of the turntable 702, so that the turntable 702 can be anti-skid when the fingers rotate it.

[0033] like Figure 3 As shown, the first metal tube 2 and the second metal tube 3 are on the same horizontal line;

[0034] In this embodiment, the first metal tube 2 and the second metal tube 3 are on the same horizontal line, which facilitates the first suture needle 4 and the second suture needle 5 to slide linearly between the lumens of the first metal tube 2 and the second metal tube 3.

[0035] Working principle: When in use, the first metal tube 2 is inserted into the wound of human tissue until the end of the first metal tube 2 is against the part to be sutured, and then any one of the turntables 702 is rotated. When the turntable 702 rotates, the suture thread 6 is wound and rolled up through the rotating shaft 703. Since the tail end of the suture thread 6 is connected to the first suture needle 4 and the second suture needle 5, the suture thread 6 will make one of the first suture needle 4 or the second suture needle 5 connected to it protrude from the end of the first metal tube 2, and then use a tool to pull out the protruding first suture needle 4 or the second suture needle 5, and then rotate the other turntable 702 and operate in the same way. When the first suture needle 4 and the second suture needle 5 are all pulled out, the suture thread 6 wrapped on the two turntables 702 is removed, and then the first suture needle 4 and the second suture needle 5 are clamped at the same time and continuously pulled out until the suture thread 6 is knotted at the position where it needs to be sutured at one end away from the first suture needle 4 and the second suture needle 5.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
