Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a limb fixator. Background Art

[0002] During surgery, a limb fixation frame is often used to fix the patient's limbs to complete the nursing operation. In order to ensure the patient's treatment and facilitate the treatment of medical staff, the limbs of such patients need to be restrained to complete the treatment operation.

[0003] Among them, a patient limb fixation frame for operating room nursing disclosed in application number CN202020741932.2 is also an increasingly mature technology. Through the action of the second limit groove, the solid hollow box, the plug rod and the second spring, the limit frame and the base are rotated open under the action of the hinge. At this time, the patient's limbs can be placed on the arc plate more conveniently, and the soft cushion is fixedly connected on the arc plate, so that the patient's legs can be more comfortable. After placing the limbs, turn the handle to make the clamp move when the third threaded rod rotates up and down, so that the patient will be more comfortable during the treatment process and avoid secondary injury to the limbs.

[0004] Based on this, I agree with the advantages of the above products, but there are still the following defects:

[0005] If the patient's limbs are thin, the limbs may be unstable when the curved plates and clamps are used to fix the patient's limbs. Summary of the invention

[0006] The utility model aims to provide a limb fixator to solve the problem of unstable fixation when the limb is thin in the background art.

[0007] The embodiment of the utility model provides a limb fixator, including a clamping device and a sliding device;

[0008] Wherein, the clamping device comprises a square frame, an arc bottom plate is installed in the middle of the bottom of the inner wall of the square frame, a threaded rod is penetrated through the top of the square frame, a threaded hole matching with the threaded rod is opened on the outside of the square frame at the threaded rod, the bottom of the threaded rod is located on the inner wall of the square frame and connected with an arc top plate, a movable groove is opened at the bottom of the square frame, a positive and negative screw rod is penetrated at one end of the movable groove and extends out of the left end of the square frame, bearing sleeves are sleeved on both ends of the positive and negative screw rods located in the square frame, and two mutually symmetrical clamping plates are slidably installed on the top of the positive and negative screw rods;

[0009] The sliding device comprises a cylinder, two sliding rods are slidably installed inside the cylinders, a plurality of positioning holes are opened on the outer sides of the sliding rods, a limiting hole matching with the positioning hole is opened near the top of the cylinder, and a limiting rod is installed inside the limiting hole.

[0010] In this embodiment, by rotating the forward and reverse screw rods, the two symmetrical clamping plates are moved at equal distances relative to each other, thereby fixing the left and right sides of the limb. By rotating the threaded rod, the arc top plate is rotated synchronously, and then the arc top plate is moved up and down synchronously, so that the clamping device can surround and fix the limb in all directions, which is convenient for use on limbs of different thicknesses. The limit rod is pulled out, the cylinder and the slide rod are slid to a suitable height, the limit hole and the positioning hole are overlapped, and the limit rod is inserted into the inside of the limit hole, which is convenient for medical staff to slide the limb fixation frame up and down.

[0011] In one embodiment of the utility model, a base plate is installed at the bottom of the square frame, a support plate is installed on the front of the arc base plate, a strap is installed at one end of the support plate and connected with Velcro, a buckle is installed on the symmetrical surface of the support plate located on the strap, and two straps and buckles are installed.

[0012] In this solution, the strap is passed through the buckle, and the strap is attached through the Velcro on the strap to fix the limb.

[0013] In one embodiment of the utility model, a mounting plate is installed at the bottom of the cylinder, a mounting groove is opened inside the mounting plate, and two spiral rods penetrate the bottom of the mounting plate.

[0014] In this solution, the limb fixation frame is fixed to the edge of the patient's bed by the cooperation of the mounting plate and the spiral rod. The spiral rod is rotated to clamp the edge of the bed so that the mounting plate is stably mounted on the side of the bed.

[0015] In an implementation manner of the utility model, a rocker is installed on the outside of the positive and negative screw rods, and the rotation grooves at the tops of the threaded rods are provided with anti-slip grooves.

[0016] In this solution, the anti-skid groove can increase the friction between the threaded rod and the finger, prevent the threaded rod from sliding, and thus improve stability.

[0017] In an implementation manner of the utility model, a fixing block of a flat-top cone is installed on the top of the spiral rod, and a round rod is movably penetrated through the bottom of the spiral rod.

[0018] In this solution, the fixing block can increase the contact surface of the bed edge, so that the mounting plate can be clamped more stably, and the round rod is convenient for sliding the rotating spiral rod left and right.

[0019] In one embodiment of the utility model, the bottom of the base plate is connected to a sliding rod, and the corresponding surfaces of the arc base plate, arc top plate, clamping plate, mounting plate and fixed block are all installed with foam pads, and the widths of the arc base plate, arc top plate and clamping plate are all wider than the square frame.

[0020] In this solution, the foam pad can increase the friction of the limb fixation frame and improve the stability.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The limb is fixed by passing the strap through the buckle and sticking it through the Velcro on the strap. When the rocker is rotated, the rotation of the rocker drives the positive and negative screw rods to rotate synchronously, so that the two symmetrical clamping plates move relative to each other at an equal distance, thereby fixing the left and right sides of the limb. The rotating groove is rotated, and the rotating groove drives the threaded rod to rotate. Since the bottom of the threaded rod is connected to the arc top plate, the arc top plate rotates synchronously, and then the arc top plate moves up and down synchronously. Foam pads are installed on the corresponding surfaces of the arc bottom plate, the arc top plate, the clamping plate, the mounting plate and the fixing block. The foam pads can increase the friction of the limb fixing frame, improve the stability, and enable the clamping device to surround and fix the limb in all directions, which is convenient for use of limbs of different thicknesses. The limb fixing frame is stably fixed through double fixation. BRIEF DESCRIPTION OF THE DRAWINGS
