Problems solved by technology

[0005] However, due to the differences in the shape and size of human bones, the locking plate needs to be adapted to the physiological and anatomical shape of the scapula during surgery, and the shape of the locking plate needs to be bent, twisted, cut off, etc. At present, there is no special locking plate bending instrument for the fracture site at the medial edge and the lateral edge, which causes great inconvenience to the doctor during the operation, and also causes the locking plate to not fit well with the fracture site of the scapula. combined and fixed, thus affecting the postoperative recovery effect of the patient

Embodiment 1

[0042] Embodiment 1: A kind of reset shaping instrument for scapula reconstruction surgery, such as figure 1 As shown, it includes a first tong arm 1 and a second tong arm 2 pivotally connected to each other. The first pliers arm 1 includes a first clamping portion 11 and a first pliers handle 12, and the first clamping portion 11 is provided with an abutment surface 111 that is partially attached to the locking plate 3; the second pliers arm 2 includes a second clamping The holding part 21 and the second pliers handle 22 , the second holding part 21 is provided with a driving part 211 , and the driving part 211 cooperates with the fitting surface 111 to bend the locking plate 3 .

[0043] Such as figure 1 As shown, in this embodiment, the bending instrument is suitable for bending the locking plate 3 before scapula reduction orthopedics. Wherein, the first clamping portion 11 includes a first connecting block 112 and a first bending block 113, the cross section of the first...

Embodiment 2

[0048] Embodiment 2: A kind of reset shaping instrument for scapula reconstruction surgery, such as Figure 4 As shown, the difference from Example 1 is that this bending instrument is suitable for bending the locking plate 3 in the scapula reduction orthopedic operation, that is, when the locking plate 3 has been fitted to the scapula, and the locking screw is driven in to make the locking plate 3 3 Preliminary fixation with the scapula, but still needs fine-tuning.

[0049] Such as Figure 4 As shown, the first clamping part 11 includes a left clamping block 115 integrally formed with the end of the first pliers handle 12, and the second clamping part 21 includes a right clamping block 214 integrally formed with the end of the second pliers handle 22 , the driving part 211 includes an extruding block 2142 integrally formed on the end of the right clamping block 214 away from the second pliers handle 22 . The side of the left clamping block 115 facing the right clamping blo...

Abstract

The invention discloses a repositioning and shaping instrument for scapula reconstruction surgery, which belongs to the field of medical instruments, and includes a first pincer arm and a second pincer arm pivotally connected to each other, and the first pincer arm includes a first clamping part and a second pincer arm. The first clamp handle, the second clamp arm includes a second clamping part and a second clamp handle; the first clamping part is provided with a fitting surface that fits with the locking plate part, and the second clamping part It is provided with a driving part that cooperates with the fitting surface and bends the locking plate. The present invention is applicable to the locking plate used at the fracture site at the medial edge or the lateral edge of the scapula, and is convenient for adaptively bending the locking plate before or during the operation, so that the locking plate fits the fracture site better and helps The effect of fracture rehabilitation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a reduction and shaping device for scapula reconstruction surgery. Background technique [0002] The scapula, also known as the scapula or the lute, is located behind the ribcage and is a triangular flat bone. The scapula consists of two faces, three corners and three margins, of which the subscapular fossa is a large and shallow fossa in the front; there is a transverse bony crest in the back called the spine of the scapula, and the shallow fossa above and below the spine are called the scapular fossa respectively. It is the supraspinatus fossa and infraspinatus fossa. The lateral side of the scapular spine is flat, called the acromion, which is the highest point of the shoulder. The lateral horn is thick and has a pear-shaped articular surface, which is called the glenoid; the upper and lower horns are located at the upper and lower ends of the medial border The lower ...
