Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly to a nail guide plate based on palm and finger joint traction. Background Art

[0002] Finger contracture release and mallet finger are generally treated surgically. Fixing the Kirschner wires in the appropriate positions of the phalanges and finger joints is a key technique in surgery. Currently, surgical operations still require doctors to perform manual fixation, and the position of the Kirschner wires is evaluated through intraoperative fluoroscopy after fixation. There is blindness in the needle placement, and the small anatomical characteristics of the phalanges do not allow multiple needle placement adjustments.

[0003] Therefore, the traditional surgical method has the following defects: 1) The operation requires high concentration, physical strength, and fixation and traction of the palm and fingers of the affected side by hand, which places high demands on the operator; 2) The vibration caused by the force generated during the operation may cause the operator's fingers and palms to become numb and loose, and then cause displacement, resulting in prolonged operation time and deviation in screw placement; 3) The optimal screw placement position is often judged based on subjective experience, and multiple adjustments cannot be made during the operation. Utility Model Content

[0004] The purpose of the utility model is to provide a nail guide plate based on palm and finger joint traction, which has the function of fixing the affected finger and accurately fixing the needle position, greatly reducing the risk of surgery.

[0006] Furthermore, the affected finger fixing structure includes a finger fixing structure and a back of hand fixing structure; the finger fixing structure is a finger sleeve-like structure that is sleeved on the outside of the affected finger; the back of hand fixing structure is a covering structure used to cover and fix the back of the hand; a needle placement catheter is provided at the fingertip of the finger fixing structure; fixing blocks are respectively provided on the finger fixing structure and the back of hand fixing structure, and a plurality of fixing holes are provided on the fixing blocks; the relative positions of the finger fixing structure and the back of hand fixing structure are fixed by Kirschner wires that pass through the fixing holes on the fixing blocks of the finger fixing structure and the back of hand fixing structure in sequence.

[0007] Furthermore, the affected finger fixation structure includes a middle phalanx fixation structure and a terminal phalanx fixation structure; the middle phalanx fixation structure is a finger sleeve-like structure covering the middle joint of the affected finger, and the terminal phalanx fixation structure is a finger sleeve-like structure covering the terminal joint of the affected finger; the middle phalanx fixation structure and the terminal phalanx fixation structure are movably connected; the fingertips of the middle phalanx fixation structure and the terminal phalanx fixation structure are respectively provided with needle catheters.

[0008] Further, the needle catheter at the finger end of the terminal phalanx fixation structure limits the mid-terminal phalanx fixation structure.

[0009] The specific sizes and specifications of the above components must be adjusted for the patient's hand characteristics, as follows:

[0010] 1. Mechanical traction of the affected (contractive) fingers, fixed traction of the fingers using gypsum, low-temperature thermoplastic plates, splints, etc., and the position of the fingers needs to be maintained at the same time.

[0011] 2. Perform imaging examination (CT or MRI) and reconstruct the affected fingers and palms, including bones and skin.

[0012] 3. Reconstruct bone and skin, use the software with a diameter greater than 2mm, simulate the placement of Kerry pins, combine fingers and palms and other skins, and design nail guides.

[0013] 4. Export the drawing documents of nail guide plates and manufacture the physical guide plates through machine tools.
