Description

Technical Field

[0001] The invention belongs to the technical field of medical appliances, and in particular relates to a device for fixing body position during an olecranon fracture operation. Background Art

[0002] The protrusion under the skin behind the proximal end of the ulna is the olecranon. It forms a semilunar notch with the coronoid process of the ulna in front. This notch forms a joint with the trochlea of ​​the humerus. The ulnohumeral joint only has flexion and extension activities. Olecranon fractures are intra-articular fractures that affect the semilunar notch. Therefore, anatomical reduction is an effective measure to prevent joint instability and prevent osteoarthritis and other complications. Olecranon fractures are a common type of fracture in clinical practice, which often occurs in adults and accounts for about 10% of adult upper limb fractures. Direct violence and indirect violence can cause olecranon fractures. There are two common causes of olecranon fractures: 1. Indirect external force: When falling, the elbow joint is in a straight position, and the external force is transmitted to the elbow, and the triceps pulls to cause an avulsion fracture. The fracture line may be transverse or oblique. There is separation between the two fracture ends; 2. Direct external force: When falling, the elbow joint is straightened and the elbow lands, or it is directly hit behind the elbow, resulting in a comminuted fracture, and the fracture ends are mostly not separated. Olecranon fracture is an intra-articular fracture. In treatment, we should strive to achieve anatomical reduction to ensure the smoothness of the joint surface, thereby reducing the occurrence of traumatic arthritis and promoting the recovery of elbow joint function. At present, the main treatments for olecranon fracture are non-surgical treatment and surgical treatment, but only a few literature reports on the use of non-surgical treatment for olecranon fracture. Surgery has now become the mainstream treatment method. However, how to position the body during surgery to facilitate intraoperative operations while not affecting intraoperative fluoroscopy has always been controversial. In clinical practice, the general intraoperative position is supine, with the shoulders and elbows flexed in front of the chest, which is more convenient for intraoperative movement of the affected limb and fluoroscopy.

[0003] However, due to the lack of an effective position fixation device during surgery, on the one hand, the forearm is placed in front of the chest, which affects the mobility of the chest; on the other hand, due to the lack of effective fixation of the affected limb, a dedicated assistant is required to fix the affected limb on the opposite side or the operating side, which is not conducive to the operation and increases the possibility of intraoperative contamination. Therefore, it is necessary to improve the structure of position fixation, and at the same time, a device for position fixation during olecranon fracture surgery is proposed to better solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a device for body position fixation during olecranon fracture surgery in order to solve the above-mentioned problem.

[0007] In a preferred embodiment, a hollow groove is opened at the bottom of the placement plate, and a screw is movably installed in the hollow groove through a bearing. The screw movably passes through the right wall of the placement plate, and the other end is movably installed with the left wall of the placement plate through a bearing.

[0008] In a preferred embodiment, a movable block is threadedly connected to the screw rod, and a connecting column is fixedly connected to the bottom of the movable block, and the bottom of the connecting column is fixedly connected to the fixing plate.

[0009] In a preferred embodiment, the placement groove is a U-shaped structure, and a relatively arranged soft pad is fixedly installed on the opposite surface of the pressing plate.

[0010] In a preferred embodiment, limiting grooves are opened on both sides of the top of the placing plate, and the bottom of the connecting rod is hinged in the limiting grooves, a slot hole is opened at the bottom of the connecting rod, and a limiting rod is inserted in the slot hole, both ends of the limiting rod are fixed on the inner wall of the limiting groove, and a spring is sleeved on the limiting rod.

[0011] In a preferred embodiment, a handle is fixedly mounted on one end of the screw rod away from the placement plate, and the handle is located above the fixed plate.

[0012] In a preferred embodiment, the tray device is composed of a chassis, a hydraulic rod, a baffle, a fixed rod, a gauze tube and a placement groove. The hydraulic rod has two groups, and one end of the hydraulic rod is hinged on the right wall of the chassis, and the other end is hinged at the bottom center of the chassis. The left side of the chassis is hinged to the top right side of the chassis.

[0013] In a preferred embodiment, baffles arranged opposite to each other are fixedly installed on the four sides of the top of the chassis, and a fixing rod is fixedly installed between the baffles near the left side, the number of the fixing rods is not less than three, and each fixing rod is movably sleeved with not less than three hooks, a gauze tube is fixedly installed between the baffles near the right side through a bearing, a placement groove is opened on the chassis, and the placement groove is located between the gauze tube and the fixing rod, a cover plate is movably installed on one side of the baffle through a hinge, and a handle is fixedly installed on the side of the cover plate away from the hinge.

[0014] In summary, due to the adoption of the above-mentioned technical scheme, the beneficial effects of the present invention are: the patient's forearm is effectively fixed, and can be moved forward, backward, up and down, which is convenient for medical staff to perform surgical operations, and at the same time, no extra assistants are required for operation and fixation, which saves manpower and reduces the possibility of intraoperative contamination.

[0015] 1. In the present invention, since the extrusion clamp is connected with a threaded rod, when the threaded rod is rotated, the extrusion clamp can be moved closer to the fixing clamp, thereby fixing the device on the bed, effectively making the device more stable and reducing the pain of the patient. At the same time, since the sliding block is connected with a bolt, when the height of the device is too high or too low, the sliding block can be moved up and down to a suitable position, and then the bolt is rotated and pressed against the base frame to fix the sliding block. The up and down movement of the device can be flexibly controlled, which provides great convenience for medical staff during surgery and indirectly reduces manpower consumption.

[0016] 2. In the present invention, when the patient lies on the bed, it is inconvenient for him to stretch his arms. At this time, the screw is rotated by the handle to drive the movable block to rotate. Since the connecting column at the bottom of the movable block is fixedly connected to the fixed plate, the placement plate will move left and right under the action of the screw, so as to be controlled in a suitable position. It is very simple and convenient. The compression plate is opened, and the patient puts his arm in the placement groove, and then covers it with a disinfectant towel. Under the action of the spring and the limit rod, the compression plate will automatically move together and fix the patient's wrist on the placement groove, which greatly improves stability and is convenient for medical staff to perform surgical operations. At the same time, no extra assistants are required to perform operation and fixation, which saves manpower and reduces the possibility of intraoperative contamination.

[0017] 3. In the present invention, when the medical staff is in the operation process, there is no need to frequently find the surgical tool, which delays the patient's treatment time and prolongs the patient's pain. They only need to open the hydraulic rod to raise the chassis, and then hang the scalpel or surgical scissors on the hook on the fixed rod, so that they can easily distinguish and select the tool to be used. At the same time, the gauze used for bandaging can be placed on the gauze tube, which effectively saves the operation time and does not require assistants to deliver it again, saving manpower. When there is nowhere to put things that are inconvenient to place during the operation, they can be placed in the placement slot, which saves a lot of space and makes it easy for doctors to find medical instruments and get them at hand.
