Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multi-angle puncture and suturing device for arthroscopic surgery. Background Technology

[0002] In the field of arthroscopic surgery, traditional suturing mainly relies on traditional guide wires. Specifically, a guide wire is first inserted through the lower edge of the incision and then ejected. Next, a bird-beak forceps is inserted through the upper edge of the incision to grasp the guide wire, pull it out, insert the suture, and then pull the guide wire back to retrieve the suture. Finally, the knot is tied. However, this traditional method has many drawbacks. First, the procedure is extremely cumbersome and time-consuming, undoubtedly increasing the potential risk of tissue damage. Second, frequent tool switching is required during surgery, which not only inconveniences the procedure but also prolongs the operation. Third, slippage or inaccurate positioning can easily occur during suture transfer and fixation, negatively impacting surgical precision. Fourth, when facing confined surgical spaces such as the hip joint capsule, the flexibility of traditional instruments is severely insufficient, making it difficult to meet the needs of complex surgical procedures.

[0003] Given the aforementioned problems with traditional arthroscopic suturing methods, there is a pressing need for a multi-angle puncture and suturing device for arthroscopic surgery. This novel device aims to improve surgical efficiency and reduce damage to patient tissues, thereby better serving clinical arthroscopic surgery. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0034] Example

[0035] This embodiment provides a multi-angle puncture and suturing device for arthroscopic surgery, including: a first hand handle 1, a second hand handle 2, and a clamping rod assembly 3 hinged to one end of the first hand handle 1 and the second hand handle 2;

[0036] Both the outer surfaces of the first hand handle 1 and the second hand handle 2 are fixedly provided with corrugated anti-slip strips; the corrugated anti-slip strips provided on the outer surfaces of the first hand handle 1 and the second hand handle 2 provide doctors with a stable grip and reduce the risk of instruments slipping during operation. Especially during long-term surgery or delicate operations, they can effectively reduce doctors' hand fatigue and ensure the stability of operation.

[0037] The clamp assembly 3 includes: a first clamp 31 fixedly disposed at one end of the first hand handle 1, a second clamp 32 hinged to one end of the second hand handle 2, and a third clamp 33 slidably disposed at the end of the second clamp 32 away from the first hand handle 1;

[0038] The first clamp bar 31 is hinged to the second hand handle 2 on the side near the second clamp bar 32;

[0039] Wherein, the end of the second clamp bar 32 away from the first hand handle 1 is hinged to the middle of the third clamp bar 33, one end of the third clamp bar 33 is hinged to one side of the first clamp bar 31, and the other end of the third clamp bar 33 is fixedly provided with a first clamp 4;

[0040] Wherein, a second clamp 5 is fixedly provided at the end of the first clamp bar 31 away from the first hand handle 1;

[0041] The first clamp 4 has a positioning hole 41 along the thickness direction, and the second clamp 5 has a hollow metal spike 51 fixedly provided on the side near the first clamp 4. A detachable thread end 52 is provided on the hollow metal spike 51, and the hollow metal spike 51 matches the positioning hole 41.

[0042] The suture head 52 is composed of a cone at the top and several frustums fixedly disposed at the bottom of the cone, so that the cross-section of the suture head is fishbone shaped. The radius of the bottom surface of the cone and the radius of the bottom surface of the frustums are larger than the radius of the positioning hole 41. The bottom of the suture head 52 is fixedly provided with a suture 54. The suture head 52 can stably cooperate with the positioning hole 41, effectively avoiding slippage. After puncture, the first clamp 4 and the second clamp 5 are separated by releasing the first hand handle 1 and the second hand handle 2. The suture head 52 is carried out by the positioning hole through the hollow metal barb 51, leaving the suture in the tissue, improving the accuracy of the operation and reducing the adverse effects of inaccurate suture positioning on the surgical outcome.

[0043] It also includes: a first spring 6, a baffle 7 fixedly disposed on the second clamp 32, and a sliding support 8 fixedly disposed on the first clamp 31;

[0044] One end of the first spring 6 is fixedly disposed on the side of the first hand handle 1 near the second hand handle 2, and the other end of the first spring 6 is fixedly disposed on the side of the second hand handle 2 near the first hand handle 1. The first spring 6 allows the first hand handle 1 and the second hand handle 2 to be in a naturally open state, which conforms to the ergonomic design. Doctors do not need to exert force to maintain the open state of the instrument at all times, making operation easier.

[0045] The second clamp 32 slides through the sliding support 8, and there is a gap between the baffle 7 and the sliding support 8;

[0046] This also includes the housing 10;

[0047] The first clamp 31, the second clamp 32, and the third clamp 33 are disposed in the housing 10.

[0048] In one preferred embodiment, the third clamp rod 33 is a straight rod, or a left-bent rod bent to the left, or a right-bent rod bent to the right; the end of the first clamp rod 31 near the second clamp 5 has the same bending angle as the third clamp rod 33. The third clamp rod 33 can be straight, left-bent, or right-bent, and the end of the first clamp rod 31 near the second clamp 5 has the same bending angle, which allows the device to be flexibly adjusted according to the spatial structure and needs of different surgical sites.

[0049] In use, the shapes of the third clamp 33 and the first clamp 31 can be appropriately selected according to the needs of the surgical site for ease of operation. Then, holding the first handle 1 and the second handle 2, the device is inserted into the surgical site through the working channel of the arthroscopy. The doctor controls the first handle 1 and the second handle 2 to align the hollow metal spike 51 of the second clamp 5 with the tissue area to be sutured. Due to the presence of the first spring 6, the handles are in a naturally open state, facilitating the doctor's operation. When puncture is required, the doctor pinches the first handle 1 and the second handle 2. At this time, the second clamp 32 slides within the sliding support 8, driving the clamp assembly 3 to move, thereby opening and closing the first clamp 4 and the second clamp 5, and opening the hollow metal spike 51. The puncture needle 51 pierces into the tissue. After the hollow metal needle 51 pierces, the suture head 52 also pierces the tissue. Since the suture head 52 has a fixed suture 54 at its bottom and the suture head 52 has a special fishbone-shaped structure consisting of a top cone and several bottom truncated cones, the radius of the bottom surface of the cone and truncated cones is larger than the radius of the positioning hole 41. When the conical part at the top of the suture head 52 passes through the positioning hole 41, the handle is released, causing the first clamp 4 and the second clamp 5 to separate. The suture head 52 is brought out of the hollow metal needle 51 through the positioning hole, thus leaving the suture 54 in the tissue. After completing one puncture, the suture head 52 is taken out from the positioning hole 41, reloaded into the hollow metal needle 51, and the repositioning device completes the second puncture.

[0050] In summary, this invention simplifies the surgical procedure, eliminating the need for multiple switching of tools such as suture guides and beak forceps as in traditional methods. This reduces the number of steps involved in the surgery, shortens the surgical time, and directly reduces the potential risk of damage to the patient's tissues. It also reduces other risks such as infection caused by prolonged surgery. Furthermore, the entire operation is smooth and easy to control, reducing the difficulty and workload for doctors and improving the success rate and quality of the surgery.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
