Moulding apparatus that resets of operation usefulness is rebuild to scapula

Technical Field

The invention relates to the technical field of medical instruments, in particular to a resetting and shaping instrument for a scapula reconstruction operation.

Background

The scapula, also called scapula and lute bone, is located behind the thorax and is a triangular flat bone. The scapula comprises two faces, three corners and three edges, wherein the front face is a subscapular fossa which is a large and shallow fossa; the back of the spine is provided with a transverse bone ridge called as a scapular spine, shallow pits above and below the spine, called as supraspinatus pit and infraspinatus pit respectively, the outer side of the scapular spine is flat, called as a acromion, is the highest point of the shoulder, the outer side corner is thickened, and the spine is provided with a pear-shaped articular surface called as a glenoid; the upper corner and the lower corner are positioned at the upper end and the lower end of the inner side edge and can be used as marks of counting ribs; the medial aspect is long and thin, facing the spine, the lateral aspect is thick, facing the axilla.

The classification system of scapulae is relatively complex, no unified classification standard exists at present, and common classification methods include Hardegger classification, Mille classification and classification of bone trauma orthopedics Association of International internal fixation research (AO)/OTA (OTA), wherein the Hardegger classification can be specifically divided into scapula body fracture, scapula pelvis marginal fracture, scapula glenoid fossa fracture, anatomical neck fracture, surgical neck fracture, acromion fracture, scapula spine fracture and coracoid process fracture. The geometrical shape of the scapula is very irregular, the anatomical position is deep, and the number of muscles attached is large, so the probability of fracture nonunion is high, after the scapula fracture is healed, on one hand, the fracture is determined by the damage degree of the fracture, on the other hand, close relation is formed between the scapula fracture and good operation reduction and fixation, and the types of selectable materials for internal fixation treatment are more, such as: reconstruction steel plate, T-shaped steel plate, deformed steel plate, calcaneus steel plate, Kirschner wire, steel wire, absorbable and non-absorbable screw and the like.

The first clamping portion 11 includes a first connecting block 112 and a first bending block 113, the cross section of the first bending block 113 is a right triangle (or an obtuse triangle), and the two acute ends are respectively formed integrally with the first connecting block 112 and the first forceps handle 12. The first bending block 113 is further integrally formed with a second connecting block 114, the first connecting block 112 and the second connecting block 114 are arranged in parallel, and a certain space is formed between the first connecting block and the second connecting block. The second clamping portion 21 includes a pivot block 212 pivotally connected between the first connecting block 112 and the second connecting block 114, and the pivot block 212 is integrally formed with the second forceps handle 22 through the driving portion 211; the driving portion 211 is an arc-shaped block, a side surface of the first bending block 113 facing the driving portion 211 is a bonding surface 111, and the bonding surface 111 is an arc-shaped surface.

As shown in fig. 1, a placement groove 2122 is formed on one end surface of the pivot block 212 and near the driving portion 211, and a bending space is formed between the placement groove 2122 and the first connecting block 112, the first bending block 113, and the first forceps handle 12. In a specific implementation process, the strip-shaped locking plate 3 can horizontally or vertically lap on the first connecting block 112 and the first forceps handle 12, after the first forceps handle 12 and the second forceps handle 22 are rotated in opposite directions, the driving portion 211 can move towards the abutting surface 111, and the locking plate 3 can be bent according to the radian of the abutting surface 111 by the matching of the driving portion 211 and the abutting surface 111.

As shown in fig. 1, in order to prevent the locking plate 3 from being separated from the bending space due to the action of the pressing force when the locking plate 3 is bent horizontally, the joint between the attachment surface 111 and the first connecting block 112 and the joint between the first caliper handle 12 are both provided with a blocking groove 1111, before the locking plate 3 is pre-bent, the strip-shaped locking plate 3 can be placed into the blocking groove 1111 by overlapping the first connecting block 112 and the first caliper handle 12, and the blocking groove 1111 can be used for abutting the upper and lower end surfaces of the horizontally arranged strip-shaped locking plate 3 during the bending process, so that the locking plate 3 is not easy to jump.

As shown in fig. 2, in order to further increase the bending applicability of the bending apparatus, a bending arc surface 1141 is disposed on a side surface of the second connecting block 114 facing the driving portion 211, and a bending column 213 is disposed on a side surface of the pivot joint block 212 corresponding to the bending arc surface 1141, so that the locking plate 3 can be horizontally or vertically attached to the second connecting block 114 before operation, and the locking plate 3 can be bent to an arc consistent with the bending arc surface 1141 by using the bending column 213 and the bending arc surface 1141.

Example 2: a reduction shaping instrument for the scapula reconstruction surgery is different from the reduction shaping instrument in the embodiment 1 in that the bending instrument is suitable for bending a locking plate 3 in the scapula reduction orthopedics, namely, when the locking plate 3 is attached to the scapula, a locking screw is driven to fix the locking plate 3 and the scapula preliminarily, but fine adjustment is still needed.

As shown in fig. 4, the first clamping portion 11 includes a left clamping block 115 integrally formed with the end of the first handle 12, the second clamping portion 21 includes a right clamping block 214 integrally formed with the end of the second handle 22, and the driving portion 211 includes a pressing block 2142 integrally formed with the end of the right clamping block 214 remote from the second handle 22. The side of the left clamping block 115 facing the right clamping block 214 is provided with an avoiding groove 1151 and a forming groove 1152, the fitting surface 111 is formed between the avoiding groove 1151 and the forming groove 1152, the part of the extrusion block 2142 connected with the right clamping block 214 and the side facing the left clamping block 115 are vertically fixed with an overlapping block 2141, the overlapping block 2141 is arc-shaped, and the radian direction of the overlapping block 2141 is consistent with the rotation direction of the second forceps handle 22. When the locking plate 3 is horizontally attached to the attachment surface 111 (see fig. 5), the first forceps handle 12 and the second forceps handle 22 are rotated in opposite directions, the locking plate 3 can be bent by the pressing block 2142 and the attachment surface 111, and at this time, the arc-shaped block is inserted into the avoiding groove 1151.

The specific implementation process comprises the following steps: before surgery, the locking plate 3 for the inner edge or the outer edge of the scapula may be pre-bent using the bending device disclosed in example 1, the locking plate 3 is placed on the fracture site in a fitted manner, and then the locking plate 3 and the scapula are clamped by a plurality of bone clamps (as shown in fig. 6) and locking screws are driven. If the locking plate 3 still needs to be adjusted finely, the physician can hold the first and

second handles

12 and 22 of the bending instrument disclosed in embodiment 2, make the connecting strip 32 of the locking plate 3 abut against the abutting surface 111 and the overlapping block 2141, and press the connecting strip 32 by the pressing block 2142 to achieve the intraoperative bending of the locking plate 3. Wherein the distance between the overlapping block 2141 and the end face of the head of the pressing block 2142 is smaller than the thickness of the connecting strip 32, so that the locking plate 3 does not interfere with the scapula when bending during the operation.
