Abstract
Description
本發明係有關於一種醫療用輔助套件，特別係有關於一種可確認髓內釘彎曲方向之植入髓內釘之輔助套件。
The present invention relates to a medical auxiliary kit, and more particularly to an auxiliary kit for implanting an intramedullary nail that confirms the direction of bending of an intramedullary nail.
習知髓內釘400，請參閱第10圖所示，其具有一彎曲變形方向S1，其係可以外科手術植入骨頭之骨髓中，並藉由該髓內釘400具有彎曲變形之特性，以固持一骨頭500，一般於進行手術前，必需預先計畫一在該骨頭500中之較佳的髓內釘彎區方位S2，該髓內釘彎區方向S2係為該髓內釘400植入該骨頭500之骨髓後之較佳彎曲變形方向，接著，於進行髓內釘植入手術時，需施以旋轉及鎚擊動作，以使該髓內釘400可順利植入於該骨頭500之骨髓中，當植入該髓內釘400後，必需對該髓內釘400施予特定溫度，以使該髓內釘400產生形變而彎曲至該髓內釘彎區方位S2，然由於植入手術過程中之旋轉動作，常導致無法正確掌握植入於該骨頭500中之該髓內釘400之彎曲變形方向S1與手術前所計畫之該髓內釘彎區方向S2一致，因此大幅降低手術的成功率並且增加了髓內釘植入手術之困難度。
The intramedullary nail 400, as shown in FIG. 10, has a bending deformation direction S1 which can be surgically implanted into the bone marrow of the bone, and has the characteristics of bending deformation by the intramedullary nail 400. Holding a bone 500, generally before the operation, it is necessary to pre-plan a preferred intramedullary nail orientation S2 in the bone 500, and the intramedullary nail direction S2 is the intramedullary nail 400 implant. The preferred direction of bending deformation of the bone 500 after the bone marrow, and then, during the intramedullary nail implantation operation, a rotation and hammering action is required to enable the intramedullary nail 400 to be smoothly implanted in the bone 500. In the bone marrow, after the intramedullary nail 400 is implanted, the intramedullary nail 400 must be given a specific temperature to deform the intramedullary nail 400 and bend to the intramedullary nail region S2, but due to implantation The rotational motion during the operation often results in the inability to correctly grasp the direction of the bending deformation S1 of the intramedullary nail 400 implanted in the bone 500, which is consistent with the direction S2 of the intramedullary nail region planned before the operation, thereby greatly reducing Surgery success rate and increased difficulty in intramedullary nail implantation

The axial direction of the cannula 110 extends through the hole 112. The intramedullary nail 200 has a predetermined bending direction A. When the intramedullary nail 200 is inserted through the auxiliary set 100 for implanting the intramedullary nail, the intramedullary nail is inserted into the intramedullary nail 200. The predetermined bending direction A of the nail 200 corresponds to the positioning mark 120. Preferably, the predetermined bending direction A of the intramedullary nail 200 is in the same direction as the positioning mark 120, and the intramedullary nail 200 can be a non-circular shape. In the cylinder, when the intramedullary nail 200 is subjected to a specific temperature to cause bending deformation, the intramedullary nail 200 is bent in the predetermined bending direction A, and the intramedullary nail 200 has a bending direction after the deformation and bending. The bending direction is the same direction as the positioning mark 120. Therefore, the positioning mark 120 can be used to confirm the bending deformation direction of the intramedullary nail 200 after the implantation operation.
Referring to Figures 3, 4 and 5, which are a third embodiment of the present invention, the implanted intramedullary nail assisting kit 100 further includes a coupling member 130 disposed on the grip portion 113. One end of the coupling member 130 can be screwed to the holding portion 113. The coupling member 130 has a receiving hole 131 and a joint 132. The receiving hole 131 communicates with the axial through hole 112. Referring to FIG. 3 , the intramedullary nail 200 is disposed in the auxiliary set 100 for implanting the intramedullary nail, and the intramedullary nail 200 is received in the receiving hole 131 of the coupling member 130 and the axial through hole. In the 112, the joint 132 is externally connected to a cooling device (not shown). In the embodiment, the joint member 130 is made of a metal material such as stainless steel or aluminum alloy, and the outer diameter of the joint member 130 is between Between 30 and 50 mm.
Please refer to FIGS. 5-8, which is a schematic diagram of the operation of the intramedullary nail-assisted kit 100 combined with the intramedullary nail 200 for intramedullary nail implantation. First, please refer to Figures 1, 5 and 6, When the intramedullary nail implantation operation is performed, the intramedullary nailed auxiliary kit 100 and the intramedullary nail 200 disposed in the auxiliary intramedullary nail insertion kit 100 are implanted together in a bone 300. During the implantation process, the assisting kit 100 for implanting the intramedullary nail is subjected to a rotation and hammering action, so that the implanted intramedullary nail assisting kit 100 can be implanted in the bone 300, wherein the intramedullary nail The nail 200 is also rotated synchronously with the auxiliary set 100 for implanting the intramedullary nail. In the present embodiment, the predetermined bending direction A of the intramedullary nail 200 is in the same direction as the positioning mark 120, in this embodiment. The end of the sleeve 110 forms a tapered surface 118 for facilitating implantation of the implanted intramedullary nailing kit 100 in the bone 300. Preferably, the outer wall of the sleeve 110 The 111 series is provided with a depth mark 119, which can be known by the depth mark 119 when performing an intramedullary nail implantation operation. Into the depth of the bone 300.
Referring to Figures 6 and 7, when the implanted intramedullary nail assist kit 100 and the intramedullary nail 200 are implanted together in the bone 300 and reach a predetermined depth, the cooling device (not shown) The intramedullary nail 200 is given a specific temperature by the auxiliary kit 100 for implanting the intramedullary nail to reduce the temperature of the intramedullary nail so as not to deform or slow down the deformation speed. At this time, the positioning mark 120 and the pith The bending directions of the ends of the inner nails 200 are in the same direction. Next, referring to FIGS. 8 and 9, the auxiliary implant 100 for implanting the intramedullary nails is gradually withdrawn from the bone 300, and the intramedullary nail 200 passes through the axial direction. The through hole 112 is left in the bone marrow of the bone 300 to complete the intramedullary nail implantation procedure.
In the present invention, before the intramedullary nail implantation operation, the intramedullary nail 200 is placed on the auxiliary set 100 for implanting the intramedullary nail, and the predetermined bending direction A of the intramedullary nail 200 is correspondingly implanted. The positioning mark 120 of the auxiliary set 100 of the intramedullary nail, when performing an intramedullary nail implantation operation, applies a rotation and hammering action to the auxiliary set 100 for implanting the intramedullary nail, and the intramedullary nail 200 also follows The auxiliary set 100 for implanting the intramedullary nail is synchronously rotated. The predetermined bending direction A of the intramedullary nail 200 is in the same direction as the positioning mark 120. The positioning mark 120 can correctly grasp the predetermined reservation of the intramedullary nail 200. Whether the bending direction A conforms to the bending direction of the intramedullary nail 200 in the bone 300 is pre-planned to reduce the difficulty of the intramedullary nail implantation operation and increase the success rate of the operation.
The scope of the present invention is defined by the scope of the appended claims, and any changes and modifications made by those skilled in the art without departing from the spirit and scope of the invention are within the scope of the present invention. .
