This invention discloses a foreign body removal device, belonging to the field of medical auxiliary device technology. The device includes a malleable support, a connecting rod, and a flexible wrapping band. One end of the connecting rod is connected to the malleable support, and the other end has a handle ring. The malleable support is made of medical-grade stainless steel or titanium alloy closed elastic metal ring, which can be bent and shaped while maintaining its form. Its surface is smooth and polished, the ends are rounded, and it is coated with a hydrophilic coating. The flexible wrapping band is made of medical-grade sterile degreased cotton cloth or non-woven fabric, fixed to the outer periphery of the support and featuring anti-slip texture. In use, the support adapts to the physiological curvature of the rectum to bypass the foreign body, guiding the flexible wrapping band to completely wrap the foreign body. It can then be safely expelled by pulling with the handle. This invention has advantages such as strong adaptability, stable clamping, minimal mucosal damage, and simple operation. It is suitable for minimally invasive removal of various rectal foreign bodies such as plastic, glass, silicone, and fruit pits, reducing surgical trauma and the risk of complications.

A claw-shaped steel plate fixator with guide fixing, including first claw-shaped plate and second claw-shaped plate, first claw-shaped plate and second claw-shaped plate are parallelly arranged, and reinforcing assembly is fixedly connected between first claw-shaped plate and second claw-shaped plate, first claw-shaped plate is fixedly connected with first grab block at upper and lower ends, first guide through hole is formed in the middle of two first grab blocks, and two first guide through holes are coaxially corresponding, second claw-shaped plate is fixedly connected with second grab block at upper and lower ends, second guide through hole is formed in the middle of two second grab blocks, and two second guide through holes are coaxially corresponding, the utility model overcomes the insufficient of prior art, makes whole fracture fixation process more efficient and convenient, and because it is operated basically on bone surface, greatly reduces surgical trauma, improves the postoperative recovery rate of patient.

The present application relates to the field of orthopedic rehabilitation, and in particular to a progressive correction method for rheumatoid arthritis metacarpophalangeal joint ulnar deviation deformity, aiming at the technical pain points of existing correction technology, such as large trauma, poor adaptability, easy secondary synovial membrane injury, high deformity rebound rate, poor function recovery, etc., and combining biological microdynamics, flexible material science, industrial control time sequence regulation and physical rehabilitation technology, a non-invasive time sequence closed loop correction system is constructed. Through the multi-link collaborative implementation of preoperative global accurate evaluation and mechanical anchoring, low-temperature non-inductive fascia targeted pre-loosening, flexible phase change time sequence gradient force, extensor tendon targeted homing linkage, low-frequency micro-vibration microcirculation promotion, active micro-movement compensation balance training, etc., the pathological characteristics of rheumatoid arthritis and the physiological rhythm of the hand are matched throughout the whole process, and there is no rigid compression and surgical trauma. The present application can simultaneously achieve deformity reduction, ligament release, tendon homing, inflammation relief and muscle strength reconstruction, effectively avoid surgical risks and traditional brace complications, and significantly improve the correction success rate.
