  The surgical jig 10 is made of a highly rigid material such as stainless steel. The surgical jig 10 is used as a surgical bone fixing unit for a pin-cable type internal fixation operation together with the surgical cable 20 and the fastener 30 shown in FIGS. 6 and 7, and the surgical cable 20 is connected to the fastener. Used for caulking to 30.

  As the surgical cable 20, for example, a flexible cable formed by twisting a plurality of strands made of a highly biocompatible material such as stainless steel or a polymer material is used. Note that the surgical cable 20 is not limited to a stranded wire, and may be a single wire such as a piano wire or a mild steel wire. In addition, the surgical cable 20 is fixed to the inner surface of the through hole 38 of the main body portion 32 by caulking and deforming the main body portion 32 of the fastener 30 so that the surgical cable 20 is fixed in the left and right directions of the main body portion 32. It is preferable that the plastic deformation occurs when pressure is applied from the radial direction (that is, the radial direction of the through hole).

  The fastener 30 is made of a material having high biocompatibility such as stainless steel or titanium alloy. The fastener 30 is used in an internal fixation operation for directly fixing a fractured part in the body together with the surgical cable 20 (internal fixation cable). In addition, the fastener 30 can be applied to various uses other than the internal fixation operation of the fractured part, and may be used for fixing a biological tissue or a surgical instrument, for example.

  As shown in FIG. 6, the fastener 30 is provided with a main body portion 32, a pin-like insertion portion 34 that protrudes perpendicularly to the bottom surface of the main body portion 32, and a vertical protrusion on the upper surface of the main body portion 32. A rod-shaped grip portion 36 is provided. The insertion portion 34 and the grip portion 36 are provided so as to extend on the same straight line with the main body portion 32 interposed therebetween.

  The main body portion 32 is a portion for fixing both ends of the surgical cable 20 so as to fasten the both ends of the surgical cable 20 to each other. The main body 32 is formed in a substantially rectangular parallelepiped shape, and the bottom surface and the top surface are formed in a substantially rectangular shape. The shape of the main body portion 32 is not particularly limited, but it is desirable that the left and right side surfaces are formed in a flat rectangular shape so that the body portion 32 can be easily gripped with forceps during internal fixation surgery. Moreover, in order to avoid irritation | stimulation to a biological tissue, it is preferable that the corner | angular part of the main-body part 32 is chamfered suitably.

  The main body 32 has two through-holes 38A and 38B (hereinafter simply referred to as the through-hole 38 when collectively referred to) through which the surgical cable 20 can be inserted. The through-holes 38 have the same cross-sectional shape and the same hole diameter (inner diameter), and are arranged in parallel to each other at a predetermined interval. Specifically, the through holes 38 are provided side by side in a direction parallel to the top surface and the bottom surface of the main body portion 32. The through-hole 38 is formed in a straight line and has a circular cross-sectional shape. Further, the inner diameter of the through hole 38 is formed to be slightly larger than the outer diameter of the surgical cable 20. For example, if the outer diameter of the surgical cable 20 is 1.2 mm, the inner diameter of the through hole 38 is 1. It is formed to about 3 mm.

  The main body 32 is configured to be caulked and deformed so that the through hole 38 is crushed when the left and right side surfaces are sandwiched between the surgical jigs 10 and pressed strongly. That is, the main body 32 is configured to have a strength that can be caulked and deformed. Here, the caulking deformation so that the through-hole 38 is crushed means that the main body portion 32 is plastically deformed and the cross-sectional shape of the through-hole 38 is deformed from a circular shape to an elliptical shape. By caulking and deforming the main body 32, the surgical cable 20 inserted through the through hole 38 can be caulked and fixed to the main body 32.

  The cross-sectional shape and size of the through hole 38 are not particularly limited, and the surgical cable 20 can be inserted, and when the main body portion 32 is deformed by caulking, the surgical cable 20 is crimped and fixed. Any shape and size that can be formed can be formed into various shapes and sizes such as an ellipse and a polygon. Moreover, the cross-sectional shapes and sizes of the through holes 38A and 38B may be different from each other. In the example of FIG. 6, the two through holes 38 </ b> A and 38 </ b> B are formed in the main body 32, but only one through hole may be formed in the main body 32. In that case, the shape and size of the through-hole are such that the surgical cable 20 can be passed through twice, and the surgical cable 20 can be crimped and fixed when the body portion 32 is crimped and deformed. And need to be in size.

  The insertion part 34 is a part inserted into the bone of the fracture part. The insertion part 34 is formed in a pin shape with a circular cross section, and has a diameter of about 2 mm. The insertion portion 34 is configured integrally with the main body portion 32, and the proximal end of the insertion portion 34 extends vertically from the bottom surface of the main body portion 32. The tip of the insertion portion 34 is a pointed tip-shaped portion 34A that is sharpened by double chamfering and V-shaped processing so that it can be easily inserted into the bone. In addition, the shape and the number of insertion parts 34 are not limited. For example, the shape of the insertion portion 34 is not limited to a pin shape, and may be a spike shape, for example. Further, the number of insertion portions 34 may be two or four, for example.

  The grip portion 36 is used for various operations during the internal fixation operation, for example, an operation for inserting the insertion portion 34 into the bone, an operation for passing the surgical cable 20 through the through hole 38 of the main body portion 32, or the main body portion 32. It is a portion that can be gripped by forceps, a grasping tool, a surgical instrument (for example, a drill), an operator's hand, or the like during operations such as caulking and fixing the surgical cable 20. For this reason, the grip part 36 has a chamfered part 36A on its side surface so that it can be easily grasped with forceps or the like. In addition, the grip portion 36 is unnecessary after the insertion portion 34 is inserted into the bone and the surgical cable 20 is fixed to the main body portion 32, so that the grip portion 36 can be removed from the main body portion 32 and removed. Has been. That is, the grip part 36 is detachably fixed to the main body part 32. Specifically, the connecting portion 36 </ b> B of the grip portion 36 with the main body portion 32 is tapered so as to be easily separated from the main body portion 32. By reducing the diameter of the connecting portion 36B in this manner, the grip portion 36 can be easily separated and removed from the main body portion 32 by folding at the connecting portion 36B without using a cutting tool.

  Next, an example of using the surgical jig 10 together with the surgical cable 20 and the fastener 30 to internally fix the fractured knee joint will be described with reference to FIGS.

  The procedure of the internal fixation operation will be described. First, the fasteners 30A to 30G are respectively fixed to predetermined portions of the bone 100 of the fracture portion. In the example of FIG. 7, the fasteners 30 </ b> A to 30 </ b> G are fixed to seven locations of the bone 100. The fasteners 30 </ b> A to 30 </ b> G are fixed by inserting the insertion portion 34 into the bone 100. As shown in the drawing, almost the entire insertion portion 34 is inserted into the bone 100. The number of fasteners 30, the insertion position of the insertion portion 34, and the like are appropriately selected so that the fixation of the fracture portion is optimal.

  Next, the surgical cable 20 is passed through the through hole 38 </ b> A of the main body portion 32 of the fastener 30 fixed to the bone 100. This operation is performed by grasping one end of the surgical cable 20 with tweezers or forceps and passing the thread through the needle hole. This operation is performed in order from the fastener 30A to 30B, 30C, 30D, 30E, 30F, and 30G. Next, the distal end portion of the surgical cable 20 through the through hole 38A of the fastener 30G is passed through the through hole 38B of the main body portion 32 of the fasteners 30A and 30B. Thus, the surgical cable 20 can be formed into an annular shape by passing the surgical cable 20 through the body portions 32 of the fasteners 30A and 30B in a double manner. Thereby, the surgical cable 20 is wound around the fracture part.

  Subsequently, in order to bring the surgical cable 20 wound around the fractured portion into close contact with the fractured portion with a predetermined pressure, both ends of the surgical cable 20 are clamped with forceps or the like, and tension is applied to the surgical cable 20. Add

  Next, as shown in FIG. 8, the left and right side surfaces of the main body portion 32 of the fasteners 30 </ b> A and 30 </ b> B through which the surgical cable 20 in a tension applied state is passed twice are fixed to the fixed head 13 of the surgical jig 10. It is sandwiched between the head portion 14C of the rotating head 14 and pressed strongly. As a result, the left and right side surfaces of the main body portion 32 are pressed and deformed by the protruding portions 18A of the contact portions 18 of the fixed head 13 and the head portion 14C. As a result, the through holes 38A and 38B are crushed and deformed, and the surgical cable 20 is also plastically deformed. The surgical cable 20 is caulked and fixed to the main body portion 32. Thereby, both ends of the surgical cable 20 can be fastened to each other with a predetermined tension by the fastener 30.

  At this time, the surgical jig 10 is configured so that the left and right side surfaces of the main body portion 32 of the fastener 30 are lateral in the axial direction of the grip portion 36 of the main body portion 32 (that is, the direction perpendicular to the upper surface of the main body portion 32). It can be used in the position. Therefore, even when the patient's skin, muscles, or other fasteners are obstructed and cannot be used in a direction perpendicular to the upper surface of the main body 32 of the fastener 30, the surgical jig 10 can be used. Can be used to perform the caulking work. Moreover, since the grip part 36 of the fastener 30 is inserted through the insertion hole 19 of the fixed arm 11, even when the fastener 30 has the grip part 36, the grip part 36 does not interfere with the caulking work. Further, the left and right side surfaces of the main body portion 32 are linearly sandwiched between the projecting portions 18A of the fixed head 13 and the rotating head 14, so that force is applied linearly and evenly to the left and right side surfaces of the main body portion 32 from both the left and right directions. Can be added. Thereby, the through-hole 38 can be crushed equally from both right and left sides.

  After fastening both ends of the surgical cable 20, the grip portions 36 of the respective fasteners 30 are bent and separated at the connecting portions 36 </ b> B and removed from the main body portion 32. Thereafter, the internal fixation operation is completed by performing suturing or the like. In addition, the excess part of the edge part of the surgical cable 20 is cut and removed.

  Further, when the protruding portion 18A of the fixed head 13 and the rotating head 14 is consumed by such caulking work, the fixed head 13 and the rotating head 14 are detached from the fixed arm 11 and the rotating arm 12 and replaced. can do. As a result, only the fixed head 13 and the rotating head 14 can be exchanged.

  As mentioned above, although preferred embodiment of this invention was described, this invention is not limited to the said embodiment, If it is the range which does not deviate from the meaning of this invention, it can change suitably. Moreover, all the components shown in the above embodiment are not necessarily essential, and can be appropriately selected without departing from the spirit of the present invention.
