Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a bone trauma irrigation device. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals, primarily studying the anatomy, physiology, and pathology of the musculoskeletal system. It utilizes medication, surgery, and physical therapy to maintain and develop the normal shape and function of this system. Orthopedic trauma is a subspecialty of orthopedics, specializing in fracture trauma. Fracture trauma primarily treats fractures caused by external forces or violence, such as limb fractures, joint fractures, spinal fractures, and finger replantation. Traumatic fractures have a relatively high cure rate clinically and offer a variety of treatment options.

[0003] When a limb suffers a fracture, the wound needs to be disinfected and cleaned. Next, the fracture site is immobilized and repositioned to ensure the patient's recovery. A doctor's treatment of trauma typically involves stopping bleeding, cleaning the wound, removing foreign objects, and removing necrotic soft tissue. The aim is to reduce infection and promote tissue repair. Routine irrigation and removal of foreign objects and necrotic tissue are crucial steps in ensuring wound healing.

[0004] Currently, the main methods of debridement and irrigation include: firstly, the classic saline irrigation followed by removal of foreign objects with a surgical brush; and secondly, irrigation via injection, where medication is added to the syringe for disinfection. Current debridement procedures typically require cushioning the fractured limb before the aforementioned irrigation or irrigation. Existing devices often suffer from the following technical problems: 1. They cannot effectively collect and smoothly remove the irrigation waste fluid generated during the process, leading to excessive waste fluid contamination of the medical environment; 2. They cannot adjust the distance and angle to accommodate the cushioning needs of the fractured limb in flexion; 3. The comfort level when cushioning the fractured limb is poor, and they cannot provide stable restraint while cushioning.

[0005] Therefore, there is a need to provide a bone trauma irrigation device to improve the above-mentioned technical problems. Utility Model Content

[0014] Furthermore, the lower clamping ring has two hollow sleeves with openings at both ends, and the upper clamping ring has two downwardly extending insert shafts fixedly connected to both ends; the lower clamping ring and the upper clamping ring are connected by the two insert shafts and the two sleeves through a sleeved relationship, and are constrained by the fastening knob two.

[0015] Furthermore, the top opening of the liquid collection tank is fixedly connected to an outwardly opening;

[0016] Furthermore, the bottom of the liquid collection chamber is an inclined platform with an inclined structure, and the liquid outlet is opened on the side wall at the lowest point of the inclined platform; an opening and closing valve is installed on the liquid outlet; the opening and closing valve controls the opening and closing of the liquid outlet.

[0017] Furthermore, after the constraint clamp rotates, it is tightened and limited by a fastening knob; the bottom end of the baffle is higher than the fastening knob.

[0018] Furthermore, the rotary drive component is fixedly installed on the partition plate, connecting to and driving the lead screw to rotate; a lead screw slider is fixedly connected to the bottom of the second upright, and the lead screw slider is driven by the lead screw to slide on the partition plate through the slide rail; the fixed part and the movable part are located in the same straight line in the extension direction of the slide rail;

[0024] The restraint mechanism includes a movable part and a fixed part. The distance between the movable part and the fixed part is adjustable to adapt to the rinsing needs of limbs of different lengths. It can make the bone injury site located in the middle of the two restraint clamps, so as to expose the bone injury site to the maximum extent.

[0025] The two constraint clamps are rotatably connected to the top of the first and second uprights, respectively. After rotation, they are respectively constrained by the two fastening knobs. That is, by rotating the lower clamping rings of the two constraint clamps, the angle between the two constraint clamps can be adjusted. This can better adapt to limbs that are difficult to straighten and are in a flexed state under bone trauma conditions.

[0026] The constraint mechanism is located inside the collection tank. After rinsing, the waste liquid falls into the partition inside the collection tank by its own gravity, and enters the collection chamber through the leakage hole on the partition. Under the action of the inclined platform, it flows smoothly to the outlet to be discharged smoothly from the collection tank, which facilitates the collection of rinsing waste liquid and reduces the residue of rinsing liquid in the collection tank during the discharge process.

[0039] In this embodiment, the constraint mechanism 2 includes a fixed part 201 and a movable part 202; the fixed part 201 includes a first upright 2011 and a constraint clamp 2012, and is fixedly installed on one side of the partition 101; the movable part 202 includes a second upright 2021 and a constraint clamp 2012, and the movable part 202 is driven by a rotary drive 203 and slides on the slide rail 104; the constraint clamp 2012 includes a lower clamping ring 204 and an upper clamping ring 205; the two lower clamping rings 204 of the two constraint clamps 2012 are respectively rotatably connected to the first upright 2011 and the second upright 2021. The top of 021; the rotation plane of the constraint clamp 2012 is a horizontal plane; the lower clamping ring 204 and the upper clamping ring 205 are connected to form a hollow tubular structure with open ends; the movable part 202 of the constraint mechanism 2 and the lower clamping ring 204 of the fixed part 201 respectively support the two positions of the limb with bone injury from two positions, so as to achieve stable support for the limb with bone injury and reduce the physical pressure on the limb with bone injury; the movable part 202 and the fixed part 201 can be adjusted by sliding the movable part 202 to adapt to limbs of different lengths and bone injuries of different sizes;

[0040] In this embodiment, the extension pad 3 is detachably sleeved on the lower clamping ring 204; the extension pad 3 is a long plate structure adapted to the lower clamping ring 204; the extension pad 3 is a structure that increases comfort and adaptability; specifically, the inventors found during the research process that when the lower clamping ring 204 is narrow, it may compress muscles and fat for limbs with thicker bone injuries, resulting in poor comfort. Therefore, the extension pad 3 provides a larger cushioning area, reduces sharp pressure on the limb, and enhances comfort.
