Description

Technical Field

[0001] The utility model relates to the technical field of splint fixing appliances, in particular to a splint fixing mechanism for clinical treatment of bone surgery. Background Art

[0002] Fractures are the most common problem encountered in orthopedics. Fractures refer to the complete or partial break in the continuity of the bone structure. They are more common in children and the elderly, but they also occur occasionally in young and middle-aged people. Patients usually have a fracture in one part, and a few have multiple fractures. Fracture treatment is generally divided into three stages: First, reduction, which is to restore the displaced fracture ends after the fracture to a normal or close to the original anatomical relationship in order to restore the support function of the bone. The methods of reduction include closed reduction and surgical reduction. Second, fixation. After the fracture is reduced, it is unstable and prone to re-displacement. Therefore, different methods should be used to fix it in a satisfactory position to allow it to heal gradually. Common fixation methods include: small splints, plaster bandages, external fixators, traction and braking fixation, etc. These fixation methods are called external fixation. If it is fixed through surgical incision with steel plates, steel needles, intramedullary nails, screws, etc., it is called internal fixation. Nowadays, orthopedic surgery will first reduce the fracture site, because patients need to move frequently and the fracture site cannot avoid movement. In order to avoid dislocation or twisting of the fracture site after reduction, to avoid damaging blood vessels and nerves, and to prevent the fracture site from growing unevenly, so that the broken bone can heal well after surgery, splints are currently used for fixation.

[0003] After searching, it was found that the Chinese patent with announcement number CN216495948U discloses an orthopedic splint installation and fastening device for orthopedics, including a fixing plate, wherein the upper and lower ends of the fixing plate are provided with through-holes, a threaded rod is provided inside the through-hole, and locking nuts are installed at both ends of the threaded rod, a fastening ring is provided on one side of the fixing plate, and a placement groove is provided on the inner wall of the fastening ring. The utility model has two sets of fixing structures, and a single set of fixing structures is composed of two fixing plates. The distance between the fixing plates is adjusted by the locking nuts of the threaded rod. When in use, the two ends of the orthopedic splint are respectively placed in the placement grooves inside the fastening ring, and then the threaded rod and locking nut are used to fix the fixing plate on the other side. Since the two sets of fixing structures independently control the fastening force of one end of the orthopedic splint and can be adjusted, the orthopedic splint can be fixed with a more reasonable force according to the patient's feedback.

[0004] The above utility model has the following problems:

[0005] 1. Currently, in the process of fixing a splint, a fastening belt is usually used to wrap around the outer wall of the splint to keep it fixed. Since the limb diameters of different patients are different, the length of the fastening belt needs to be adjusted when fixing the splints of different patients. The limited fixation by only wrapping the fastening belt results in poor stability, which leads to poor fixation effect of the splint.

[0006] Therefore, those skilled in the art provide a splint fixation mechanism for clinical treatment of orthopedic surgery to solve the problems raised in the above background technology. Utility Model Content

[0007] The purpose of the present utility model is to provide a splint fixing mechanism for clinical treatment of orthopedics to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A splint fixation mechanism for clinical treatment of orthopedic surgery includes a restraint belt and an external air pump inflation nozzle.

The surface of the elastic air bags is fixedly connected to a trachea, and the inlet end of the trachea is fixedly connected to an air bag inflation nozzle. The surface of the air bag inflation nozzle is provided with a quick connection mechanism for connecting to an external air pump inflation nozzle.

[0010] As a further solution of the present invention: the side wall of the restraint belt is fixedly connected with a tightening belt, and the surface of the tightening belt is fixedly connected with a Velcro sub-surface and a Velcro main surface.

[0011] As a further solution of the present invention: the side wall of the restraint belt is fixedly connected to a limiting piece, the limiting piece is circular, and the restraint belt can extend outward through the limiting piece.

[0012] As a further solution of the present invention: the quick-connect mechanism includes a fixing part, a pressure block, a spring cavity, a return spring, a ball groove and a limiting ball. The surface of the airbag inflation nozzle is slidingly connected to the fixing part, the inner side wall of the fixing part is fixedly connected to the pressure block, a spring cavity is formed between the pressure block and the airbag inflation nozzle, and a return spring is provided on the inner side wall of the spring cavity.

[0013] As a further solution of the present invention: one end of the airbag inflation nozzle is provided with evenly arranged ball grooves, and a limiting ball is placed on the inner side wall of the ball groove.

[0014] As a further solution of the present invention: a limiting groove is provided at one end of the external air pump inflation nozzle, and the limiting groove fits with the limiting ball.

[0015] As a further solution of the present invention: an annular groove is provided on the surface of the external air pump inflation nozzle, and a sealing rubber ring is fixedly connected to the inner side wall of the annular groove.

[0016] As a further solution of the present invention: a slot is provided at one end of the airbag inflation nozzle, and one end of the external air pump inflation nozzle can be inserted into the slot.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. During the initial positioning, the splint can be passed through the limiting piece through the drawstring, and then the Velcro surface and the Velcro mother surface on the drawstring are adhered to each other to limit and fix the splint. Compared with traditional metal buckles or other fixing devices, Velcro is usually lighter, reducing the burden and discomfort of the patient, and helping to improve the patient's comfort. Medical staff can easily adjust the fixation tightness and position of the splint to meet the patient's specific treatment needs. It not only provides effective fracture or injury fixation function, but also has the advantages of simple operation, strong adaptability and high comfort, which helps to promote the patient's recovery and treatment effect.

[0019] 2. When connecting the external air pump inflation nozzle, you can first toggle the fixing piece, and the movement of the fixing piece drives the pressure block to move, and the pressure block moves to compress the return spring, so that the return spring is in a compressed state, and then directly insert the external air pump inflation nozzle. After the external air pump inflation nozzle is inserted into the slot, loosen the fixing piece, and the return spring returns to its initial state after losing pressure. The movement of one end of the return spring drives the pressure block to move, and the pressure block moves to abut against the limiting ball, so that the limiting ball sinks into the limiting groove, thereby completing the limiting of the external air pump inflation nozzle, that is, completing the connection between the airbag inflation nozzle and the external air pump inflation nozzle. The connection operation of the external air pump inflation nozzle is simple and convenient, which is convenient for inflating the elastic airbag. The sealing rubber ring abuts against the inner wall of the slot to ensure the sealing effect, ensures good sealing performance, inflates the elastic airbag, and further limits it by expanding the elastic airbag. It has good wrapping, stable limit of the fixed splint, and can limit and fix limbs of different diameters. It has reasonable fixing force and strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
