Problems solved by technology

[0004] In summary, the defects of the prior art are: there is a lack of a metacarpal fracture that can fix the metacarpal fracture end in a functional position that is relatively comfortable for the patient and is convenient for functional rehabilitation, and the medical staff is easy to operate, easy to adjust in time, and has good patient treatment compliance. Fixing device; at the same time, the reset fixing device needs to be more in line with the principles of human biomechanics, more convenient and applicable, more conducive to maintaining the reset effect and improving hand function

Embodiment 1

[0039] like Figure 1-3 Shown:

[0040] A metacarpal bone fracture reduction and fixation device, comprising a volar plate 2, a dorsal plate 1 and Velcro straps 6, the volar plate 2 and the dorsal plate 1 are integrally formed plastic aluminum plates with a thickness of 1-2mm, and the volar plate 2 A layer of liner 4 matching its shape is glued to one side of the back side plate 1, and the outer surfaces of the palm side plate 2 and the back side plate 1 are covered with cotton elastic jackets 5 and sewed with Velcro straps 6;

[0041] The overall shape of the palm side plate 2 is a rectangular plate with notched corners. The right side of the rectangular plate is a rectangular ulnar side panel 201 with a width of 2 cm, and the left side is a palm panel 202. The left lower foot of the palm panel 202 has a notched corner. The corner is a right triangle, and the palm panel 202 is provided with a small hole 3;

[0042] The long 21cm of described backside plate 1, the rectangula...

Embodiment 2

[0049] like Figure 4 , Figure 5 Shown:

[0050] The metacarpal bone fracture reduction and fixation device includes a volar side plate 2 and a dorsal side plate 1, and the specific structural specifications of the volar side plate 2 are as follows: Figure 4 As shown, the overall shape is a rectangular plate with notched corners, and the size is 10cm long and 6cm wide. Open 4 groups of small holes 3 with an interval of 1 cm and a diameter of 2-3 mm to the right at the position 2 cm from the edge; Figure 4 Middle: AB section is 8cm long, BC section is 2cm long, DC section is 6cm long, AG section is 3cm long, and FD section is 4cm long. The distance between small holes 3 is 1cm. The edge is 2cm;

[0051] like Figure 5 As shown, the back side plate 1 is a rectangular plate with a length of 21 cm and a width of 3 c, which is integrally formed, and includes a wrist segment plate 102 and a palmophalangeal plate 101. A rectangular plate with a length of 17 cm and a width of...

Embodiment 3

[0053] like Figure 1-8 Shown:

[0054] The technical solution to solve the problem of metacarpal bone fracture is as follows: Firstly, manipulative restoration, taking the patient's left hand as an example, flexing the metacarpophalangeal joint and proximal phalangeal joint of the patient's left fifth finger by 90°, the surgeon hooks the patient's fifth finger with the right index finger. The proximal phalanx of the 5 fingers, the thumb is placed on the patient's fifth metacarpal head, the radial side of the middle finger joint is against the proximal metacarpophalangeal joint of the fifth finger, so that the base of the proximal phalanx supports the metacarpal head, and the surgeon's left thumb is placed At the proximal end of the patient's fifth metacarpal fracture, the remaining 4 fingers were placed on the patient's hypothenar. The operator’s left and right thumbs, index fingers, and middle fingers exert force at the same time. After a little traction, the operator’s rig...

Abstract

The invention discloses a metacarpal fracture reduction and fixation device, and relates to the technical field of medical instruments. The reduction and fixation device comprises a palm side plate, aback side plate and a hook and loop fastener belt, the palm side plate and the back side plate are made of an integrally formed plastic aluminum plate with the thickness of 1-2 mm, and a layer of liner adheres to one side of the palm side plate and the back side plate and matched with the side in shape; the outer surface of the palm side plate and the outer surface of the back side plate are bothsleeved with a cotton elastic cover, and the hook and loop fastener belt is sewn. The plastic palm side plate and the back side plate are designed according to the special anatomic form of the hand;the palm side plate and the back side plate are ingeniously combined through the hook and loop fastener belt; by maintaining the metacarpal fracture reduction effect and improving the hand function, the device can be flexibly bent into a corresponding flexion angel according to requirements, so that the fracture end is fixed to a flexion position, a function position or a hyperextension position.The metacarpal fracture reduction and fixation device is simple in structure design, easy to operate, low in cost and convenient to use and popularize at the primary level.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a metacarpal bone fracture reduction and fixation device. Background technique [0002] Metacarpal bone: also known as five fingers, a total of 5 small long bones, from the radial side to the ulnar side are the 1st to 5th metacarpal bones. Currently, known metacarpal fractures are typically represented by fractures of the neck of the fifth metacarpal. Fractures of the fifth metacarpal neck account for about 20% of hand fractures, and most of them are unstable fractures, which are prone to redisplacement and angular deformity after reduction. With the improvement of living standards and social progress, people's requirements are getting higher and higher. Young people, as a group with high incidence of metacarpal neck fractures, have higher requirements for function and aesthetics. At present, the conservative treatment of metacarpal neck fractures is still the first cho...
