Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a release hook for hallux valgus. Background Technology

[0002] Release instruments are therapeutic devices used in orthopedic and surgical clinics. They are miniature "surgical knives" that can release and separate adhesions and scar tissue in the human body, allowing for minimally invasive surgery to treat various chronic soft tissue injury-related pain conditions. Release needle therapy is a closed surgical procedure that is simple, less painful, fast-acting, inexpensive, and does not require hospitalization. It is suitable for treating many common and frequently occurring diseases in clinical practice, including sequelae of soft tissue injuries, osteoarthritis, frozen shoulder, sequelae of fractures, sequelae caused by musculoskeletal injuries, cervical spondylosis, lumbar spondylosis, and ankylosing spondylitis. However, existing release instruments cannot be operated in confined spaces, easily causing tissue damage and puncturing other tissue structures. They also cannot provide a stable path to ensure the safety and accuracy of the operation. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a release hook for hallux valgus that reduces damage to surrounding tissues, prevents accidental puncture of vital structures, adapts to the anatomy around the first metatarsophalangeal joint, provides a stable path for the blade, and ensures accurate and safe cutting. To achieve the above-mentioned objectives and other advantages of this invention, a release hook for hallux valgus is provided, comprising:

[0004] The handle portion, the hook shank portion integrally connected to the handle portion, and the hook tip portion fixedly connected to the hook shank portion;

[0005] The handle is straight;

[0006] The structure of the hook shank includes a cone, a cylinder, an arc shape, and a curved wave shape;

[0007] The hook tip is used to hook onto tissue structures, and the hook tip is fixedly attached to the end of the hook shank away from the handle.

[0008] Preferably, the hook shank is conical in shape, and includes a first conical segment and a second conical segment fixedly connected to the first conical segment. Preferably, a hook tip is fixedly connected to the end of the second conical segment away from the first conical segment, and the hook tip is needle-shaped.

[0009] Preferably, the hook shank has a curved, wavy structure, and the hook shank includes a straight rod section, a first curved section integrally connected to the straight rod section, and a second curved section integrally fixed to the first curved section.

[0010] Preferably, a hook tip is fixed to the end of the second curved segment away from the first curved segment, and the hook tip is cylindrical.

[0011] The advantages of this application compared to existing technologies are as follows: The hook tip of this application features an arc-shaped tip and a blunt end structure. The arc-shaped tip facilitates bypassing tendons and joint capsules in confined spaces, reducing damage to surrounding tissues. The blunt end structure is typically blunt, preventing accidental puncture of vital structures. Furthermore, the size and associated arc structure of the release hook in this application are adapted to the anatomy around the first metatarsophalangeal joint. By hooking the tissue with the release hook, a stable path for the blade is provided, ensuring accuracy and safety in cutting. Additionally, the anti-slip features and grooves on the handle facilitate gripping and applying lifting force. Attached Figure Description

[0014] 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.

[0015] A release hook for hallux valgus, comprising:

[0016] The handle portion, the hook shank portion integrally connected to the handle portion, and the hook tip portion fixedly connected to the hook shank portion;

[0017] The handle is a straight rod; an anti-slip component is fixed to the handle to prevent the release hook from slipping out of the hand when force is applied to it.

[0018] Furthermore, an anti-slip groove is provided in the middle part of the handle. When force is applied to the release hook, placing a finger in the anti-slip groove and then applying force to the release hook can further prevent the release hook from falling out of the hand.

[0019] The structure of the hook shank includes a cone, a cylinder, an arc shape, and a curved wave shape;

[0020] The hook tip is used to hook onto tissue structures, and the hook tip is fixedly attached to the end of the hook shank away from the handle.

[0021] Example 1: Refer to Figure 1 A release hook for hallux valgus includes: a handle portion 10, a hook shank portion 20 integrally connected to the handle portion 10, and a hook tip portion 30 fixedly connected to the hook shank portion 20. The hook shank portion 20 has a conical structure and includes a first conical segment and a second conical segment fixedly connected to the first conical segment. The hook tip portion 30 is fixedly connected to the end of the second conical segment away from the first conical segment, and the hook tip portion has a needle-like structure. The release hook has few curves in the hook shank portion 20, and the overall thickness of the hook tip portion 30 is 1.2 cm, which is thin and suitable for traction of superficial tissue structures. In use, locate the tense and contracted adductor hallucis tendon in hallux valgus, usually located below and lateral to the first metatarsophalangeal joint. Carefully pass the curved tip of the release hook under or lateral to the adductor hallucis tendon, allowing the hook tip portion 30 to stably hook the tendon while protecting deeper structures. Once the hook has firmly hooked the adductor pollicis tendon, pull the hook shank 20 upwards and outwards. The pulling action will cause the hooked tissue to become tense. Then, use a scalpel or scissors to cut the tense tissue along the groove on the inside of the hook tip 30 or close to the inside of the hook.

[0022] Example 2: Refer to Figure 2 A release hook for hallux valgus includes: a handle portion 40, a hook shank portion 50 integrally connected to the handle portion 40, and a hook tip portion 60 fixedly connected to the hook shank portion 50. The hook shank portion 50 has a curved, wavy structure and includes a straight section, a first curved section integrally connected to the straight section, and a second curved section integrally fixedly connected to the first curved section. The hook tip portion 60 is fixedly connected to the end of the second curved section away from the first curved section, and the hook tip portion 60 is cylindrical. The hook shank portion 50 of this release hook includes a multi-segment curved structure, and the overall thickness of the hook tip portion 60 is 3-5 cm, which is relatively thick and suitable for traction of deep tissue structures. In use, locate the tense and contracted adductor hallucis tendon in hallux valgus, usually located below and lateral to the first metatarsophalangeal joint. Carefully bluntly dissect the soft tissue, identify and protect important structures, especially the terminal branches of the deep peroneal nerve and the dorsal digital vein. Carefully maneuver the curved tip of the release hook under or outward from the adductor pollicis tendon. The hook tip 30 allows it to securely hook the tendon while protecting deeper structures. Once the hook is firmly hooked into the adductor pollicis tendon, pull the hook shank 20 upward and outward. This pulling motion will tense the hooked tissue. Then, using a scalpel blade or scissors, cut the tense tissue along the groove inside the hook tip 30 or close to the inside of the hook.
