Description

Technical Field

[0001] The invention belongs to the technical field of fracture reduction and fixation tools, and in particular relates to a tool for flexible fixation of fractured parts without binding. Background Art

[0002] Common surgical treatments for fixation of femoral shaft fractures include plate fixation and intramedullary nail fixation. Plate fixation is simple to operate and has a short learning cycle, but it is traumatic and has a high chance of accidental injury. It requires a large number of matching models, and infection, nonunion, delayed union, broken nails and broken plates occur from time to time. The postoperative scar is large, which affects the appearance and does not conform to the principle of minimally invasive surgery. Intramedullary nails use closed and minimally invasive techniques. Locking intramedullary nails can prevent fracture rotation deformity, reduce the risk of implant fracture, reduce the surgical infection rate, promote a high fracture healing rate, and central fixation avoids stress shielding, and the incidence of refracture is low. The intramedullary nail method conforms to the principle of minimally invasive surgery and is the current development direction, but it is difficult to operate and learn. It is difficult to lock the distal end of the intramedullary nail. Reduction is divided into closed and limited incision, but both are non-anatomical reduction, nonunion and delayed union occur, and the patient is under great pressure. Complications such as malformation and poor lower limb force line may occur after surgery. Since the intramedullary nail is a linear fixation method, the intramedullary nail fixation method cannot solve the problem of abnormal bones with large curvature such as clavicle or radius. Moreover, there is bone absorption problem during the recovery period after broken bones are connected, which affects normal recovery.

[0003] Another surgical method for diaphyseal fractures is to insert nails vertically on both sides of the fracture site. The two nails have four exposed ends. The surgeon repeatedly wraps the rope around the nail heads in an 8-shaped manner to connect and bind the two nails to the fracture area to form a strong binding relationship. Finally, the rope ends are tied and disinfected and sutured. This surgical method eliminates the trouble of using steel plate fixation and intramedullary nail fixation, but the surgical process requires the doctor to repeatedly wrap the rope, which is less efficient. The wound ropes are repeatedly superimposed on each other to form obvious bulges, especially at the nail head position, which affects the muscle suturing effect. The rope ends need to be tied with knots, and finally a protruding part is formed after the muscle is sutured, which causes strong discomfort to the patient, affects blood circulation, and affects the rehabilitation effect. Summary of the invention

[0004] In view of the problem that currently the exposed nail-piercing part of the bone fracture is treated by repeatedly wrapping a rope and finally tying a knot, thereby causing protrusion of the sutured muscle, causing discomfort and affecting blood circulation, the present invention provides a fracture binding-free fixation belt group, which is used to minimize the protrusion of the sutured muscle, reduce discomfort, promote blood circulation to facilitate rapid recovery, reduce surgical difficulty, and improve surgical efficiency.

Nails, at least two nails are respectively penetrated and fixed on both sides of the fracture site, and each main sleeve ring piece is used to be sleeved on the end of the nail exposed from the bone part. The four main sleeve ring pieces A, B, C and D are sequentially connected with the flexible connecting component to form a quadrilateral, and the main sleeve D is symmetrically flipped along the AB line to form an approximate letter-shaped structure. Or the four main sleeve ring pieces A, B, C and D are connected by a flexible connecting component to form an approximate figure-8 structure. When used, each main sleeve ring piece is used to be respectively sleeved on the exposed ends of the two nails penetrated and fixed on both sides of the fracture site.

[0006] For Solution 1, auxiliary ropes are respectively connected to the two main sleeve ring pieces at the diagonal corners of the quadrilateral, and an auxiliary sleeve ring piece is fixedly connected to the end of each auxiliary rope piece.

[0007] For solution 1, the main sleeve ring piece or the auxiliary sleeve ring piece is a round sleeve ring piece or a flat sleeve ring piece, and a locking mechanism for the flat sleeve ring piece is also provided in the case of the flat sleeve ring piece. The locking mechanism is to provide convex and concave patterns on the outer surface of the flat sleeve ring piece, and to provide a gasket with convex and concave patterns on the surface for pressing the flat sleeve ring piece, and the end of the nail has a threaded section and is installed with a lock nut, and the lock nut is screwed to compress the gasket and thus compress the flat sleeve ring piece.

[0008] For solution 1, the flexible connecting component (or rope) is integrally formed with each ring piece, or the end of the flexible connecting component (or rope) is pressed and fixed together with the ring piece, or the end of the flexible connecting component (or rope) is serially connected in the corresponding ring piece.

[0009] Solution 2 adopted by the present invention to solve its technical problem is: a fracture-free binding fixation belt group, including a ring piece and a flexible connecting component. Nails, at least two nails respectively penetrate and are fixed on both sides of the fracture site, each nail has an exposed portion, the ring piece is used to be sleeved on the end of the nail exposed from the bone part, the two ring pieces are connected together by a flexible connecting component, or the three ring pieces are connected together in turn by the flexible connecting component, or the four ring pieces are connected together in turn by the flexible connecting component. When used, each component is individually or combined to form an approximately 8-shaped structure sleeved on the corresponding nail end.

[0010] For solution 2, the sleeve ring piece is a round sleeve ring piece or a flat sleeve ring piece, and a locking mechanism for the flat sleeve ring piece is also provided in the case of the flat sleeve ring piece. The locking mechanism is to provide convex and concave patterns on the outer surface of the flat sleeve ring piece, and to provide a gasket with convex and concave patterns on the surface for pressing the flat sleeve ring piece, and the end of the nail has a threaded section and is installed with a lock nut, and the lock nut is screwed to compress the gasket and thus compress the flat sleeve ring piece.

[0031] Embodiment 1: A fracture-free binding fixation belt set, comprising: Figure 1 It can be seen that the belt set is mainly composed of a ring piece and a rope belt, the rope belt can be a rope or a side belt, and the ring piece is a flat ring piece. The connection relationship between the rope belt and each ring piece can be as follows Figure 2 The one-piece molding is shown, for example, a PVC plastic sheet is used. Or the end of the rope is pressed and fixed together with the ring sheet, for example Figure 3 As shown, the rope ends are fixed to the stainless steel ring piece by pressing, gluing, fitting or other fixing methods. Figure 4 In the connection method shown, the ends of the ropes are connected in series in the corresponding ring pieces.

[0032] from Figure 1 As can be seen in the figure, two nails are respectively inserted and fixed on both sides of the fracture site, and the ends of the two nails are respectively exposed to the bone part. In this embodiment, each main sleeve ring piece is a circular sleeve ring piece 2, and each circular sleeve ring piece 2 is respectively sleeved on the end of the nail exposed to the bone part.

[0033] Figure 1 It can be seen that the four main ring pieces A, B, C and D are connected in sequence by ropes to form a quadrilateral, and the D ring is symmetrically flipped along the AB line to form an approximately 8-shaped structure. At this time, only the two crossed ropes in the middle overlap once, and the rest of the parts do not overlap, so the overlap is small. When making this belt set, it can be as follows Figure 1 middle The quadrilateral structure shown can also be Figure 1 middle The 8-shaped structure shown, at this time, the overlapping part can be directly flattened to eliminate the overlapping part.

[0034] When the belt set of this embodiment is used in the surgical process, a suitable model is selected, and the A and B main collar pieces are first placed on the upper and lower sides of the backbone, and the center of the A and B main collar pieces is penetrated during perforation. After the first nail is fixed, the A and B main collar pieces can be connected to the end of the first nail that exposes the bone. Then the rope belt is stretched to the other side of the fracture site to pull the four main collar pieces C and D to the upper and lower sides of the backbone at the appropriate position (until it can no longer be stretched), and the center of the C and D main collar pieces is penetrated during perforation. After the second nail is fixed, the C and D main collar pieces can be connected to the end of the second nail that exposes the bone. The exposed longer part of the nail can be cut off, and the appropriate length is retained to be located outside the sutured muscle, so that the part located inside the sutured muscle, whether it is the rope belt or the collar piece, is very flat and basically has no overlapping part. Compared with the existing method of repeatedly winding the rope around the exposed ends of the two nails and finally tying them into a knot, the protrusion is significantly reduced, the surgical efficiency is improved, the surgical difficulty is reduced, the blood circulation is improved to facilitate the patient's recovery, and the patient's comfort is improved. In addition, the ropes and loops located at the inner layer of the sutured muscle can be made of degradable and absorbent materials, thereby avoiding the trouble of secondary suture removal.

[0035] Embodiment 2: Based on Embodiment 1, that is, the four main sleeve ring pieces A, B, C and D are connected in sequence by ropes to form a quadrilateral, or based on an approximately figure-8 structure, auxiliary ropes are connected to the two main sleeve ring pieces A and B respectively, and auxiliary sleeve ring pieces C' and D' are fixedly connected to the ends of each auxiliary rope. Figure 5 It can be seen that the application of this solution can not only fix the AD strap and the BC strap on the front of the fracture area, but also fix the AD' strap and the BC' strap on the back of the fracture area, thereby fixing the area around the fracture site.

[0036] Embodiment 3: Based on Embodiment 2, the auxiliary sleeve ring pieces C' and D' are replaced with flat sleeve ring pieces C" and D" respectively. Embodiment 2 usually requires the through nails to be fixed vertically to the center of the backbone, or requires the selection of a suitable fixing belt set. However, this embodiment designs an auxiliary rope belt ring structure that can be telescopically adjusted, so there is no need to strictly consider the nailing position. When nailing, it is only necessary to satisfy the positions of the four main sleeve ring pieces A, B, C and D on the front (as in Embodiment 1). The AD" rope and BC" on the back can be tensioned by telescopic adjustment after the quilt is put on.

[0037] Specifically, Figure 6 As shown, when the flat sleeve ring pieces C" and D" are used, a locking mechanism for the flat sleeve ring pieces C" and D" needs to be provided.

[0038] from Figure 6 and Figure 7 It can be seen that the present embodiment adopts a locking mechanism in which convex and concave patterns are arranged on the outer surface of the flat sleeve ring piece 4, and a gasket (including a toothed gasket 5) having convex and concave patterns on the surface of the flat sleeve ring piece is provided for pressing the flat sleeve ring piece. The end of the piercing nail has a threaded section and is equipped with a lock nut. The lock nut 6 is screwed to compress the gasket, and the gasket presses the flat sleeve ring piece against the surface of the backbone.

The outer ends of rope 1 31 and rope 2 32 are respectively connected to corresponding ring pieces, and rope 1 31 and rope 2 32 are fixedly connected by an adjustable lock. The adjustable locking is to fix the lock 33 at the inner end of rope 1 31, and a latch 35 is set in the lock 33, and a reverse tooth 34 is set in the inner section of rope 2 32. After the reverse tooth section of rope 2 32 is inserted into the lock 33, the latch 35 is inserted into the groove of the reverse tooth 34 to prevent it from moving in the opposite direction.

Compared with the existing method of repeatedly winding a rope around the exposed ends of two nails and finally tying them into a knot, the protrusion is still reduced, the surgical efficiency is improved, and the patient's comfort is improved. The rope and loop located in the inner layer of the sutured muscle can be made of degradable absorbent material, thereby eliminating the trouble of secondary suture removal.

[0042] Embodiment 6: Another fracture-free binding fixation belt assembly, comprising at least two through-pins respectively penetrating and fixing the two sides of the fracture site, such as Figure 1 The three ring pieces are connected together in sequence by ropes, such as Fig. 9As shown, each collar piece is used to be sleeved on the end of the nail exposed to the bone, and some of the round collar pieces 2 can also be replaced with flat collar pieces 4 to meet the adjustment requirements. Compared with embodiment 1 and embodiment 5, this embodiment has a collar piece at the exposed end of the nail, or two collar pieces are superimposed. Select appropriate belt assembly components to form a belt assembly as shown. Figure 1 Although there are overlapping loops, the thickness of each loop is only 0.3-0.5 mm. Compared with the existing method of repeatedly winding a rope around the exposed ends of two nails and finally tying them into a knot, the protrusion is still reduced, the surgical efficiency is improved, and the patient's comfort is improved. The rope and loop located in the inner layer of the sutured muscle can be made of degradable absorbent material, thereby eliminating the trouble of secondary suture removal.

Select appropriate belt set components to form Figure 1 Although there are overlapping loops, the thickness of each loop is only 0.3-0.5 mm. Compared with the existing method of repeatedly winding a rope around the exposed ends of two nails and finally tying them into a knot, the protrusion is still reduced, the surgical efficiency is improved, and the patient's comfort is improved. The rope and loop located in the inner layer of the sutured muscle can be made of degradable absorbent material, thereby eliminating the trouble of secondary suture removal.

[0044] Embodiment 8: Based on Embodiment 1, each rope is inserted into each ring piece, and reference can be made to Fig.12 This structure not only satisfies the connection relationship between the rope and the corresponding ring, but also can be adjusted at will, that is, after the ring A and the ring B are fixed, the position of the ring C and the ring D can be moved at will to achieve the best nailing position.

[0045] Embodiment 9: In embodiment 1 or Figure 8 On the basis of the above, after the front side of the fracture site is fixed by the fixing belt set described in the embodiment, when the back side of the fracture site is fixed again, a similar method can be selected.
