Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] The fixed frame includes a rectangular bottom plate 10, and two fixed blocks are respectively arranged on the two short sides of the rectangle. The width of the fixed block is greater than the width of the forearm, and the distance between the two fixed blocks is larger than that of the general human body from the elbow to the fingertip. the distance between. One of the fixed blocks has a structure with straps to fix the elbow. Two sliding cylinders are connected between the two fixed blocks. The two sliding cylinders are respectively located on both sides of the forearm and parallel to the direction of the forearm. Two sliding cylinders pass through the two sliding blocks. There is a strap structure on each slider. Two sliders are used to fix the wrist and palm respectively.

[0021] A circular hole 11 is respectively arranged at both ends of the fixed blo...

Abstract

The invention belongs to the field of computer-assisted surgery, in particular to a forearm and hand injection fixing device. The device includes: a first sliding block, a second sliding block, a first fixing block, a second fixing block, a strap, a sliding cylinder, and a rectangular base plate. The steps of using the device include: placing the device on a stable table top, placing the human elbow on the second fixing block with a strap, adjusting the width of the strap and fixing it; adjusting the position of a sliding block to make it Under the wrist, use the strap of the slider, adjust the width around the wrist and secure; adjust the position of the other slider so that it is under the palm, using the strap of the slider, adjust the width around the palm and Immobilization; complete injection, untie all straps, and restore patient's forearm and hand movement. Compared with the method of fixing the forearm and hand manually, the fixing frame of the present invention can ensure the immobility of the relevant limbs during the puncture injection without the need for additional personnel to fix the limbs at the same time.

Description

technical field [0001] The invention belongs to the field of computer-aided surgery, and in particular relates to a forearm and hand injection fixation device. Background technique [0002] Stroke, cerebral hemorrhage and traumatic brain injury can cause brain damage. If the injury site is located in the motor area of ​​the limbs, it will cause motor dysfunction of the limbs, manifested as the inability of the relevant limbs to move flexibly, and frequent spasms. [0003] Before physical therapy for a spastic muscle, medication injections are often required to relieve ongoing tension in the muscle. Therefore, intramuscular injection requires accurate injection of the drug into the target muscle. The human forearm and hand are the most flexible limbs, containing 18 muscles. Therefore, intramuscular injections into the forearm and hand are the most challenging. [0004] At present, clinically, in the intramuscular injection of the forearm and hand, in addition to the docto...
