Description
Technical Field
The utility model relates to the field of orthopedic surgical instruments, in particular to an orthopedic Kirschner wire universal guider, which is an adjustable guiding device used in traumatic orthopedic surgery and used for changing the screwing direction of a Kirschner wire.
Background
Trauma orthopedics is a major branch of the bone surgery profession, and research covers injuries to bones, muscles, tendons, blood vessels, nerves of the spine and limbs of the human body. With the gradual deepening and elaboration of professional division, a series of novel disciplines are differentiated and bred in the traditional research field of trauma orthopedics; such as sports medicine, microsurgery, etc. Bone injury remains the main subject of trauma orthopedics.
Skeletal injury can be understood broadly as a fracture, i.e., a break in the integrity, continuity, or lack thereof, of bone mass. Complete fractures and incomplete fractures can be classified according to the degree of injury; stable fractures and unstable fractures can be classified according to fracture stability; it can be classified into horizontal fracture, oblique fracture, spiral fracture, and comminuted fracture according to the form of fracture. Once the fracture displacement is obvious, the soft tissue is embedded, the joint surface is affected or peripheral vascular nerve injury is combined, the fracture incision reduction internal fixation operation treatment is needed.
The principle of AO (Arbeitsgememenchaftfur Osteosynylthesefragen, AO, International Interfixation research society) for surgical treatment of bone fracture is anatomical reduction, strong internal fixation, and early functional exercise. This prompts the operating physician to closely assemble the fracture pieces according to the anatomical landmarks and the fracture line morphology on the surface of the bone; the internal fixing device is installed under the condition that the fracture reduction is not lost; after the internal fixing device is fastened, the fracture reduction can be maintained and the stress applied to the bone can be resisted by functional exercise. How can the reduction of fracture be maintained during operation without affecting the placement of internal fixation devices? A series of special surgical instruments for trauma orthopedics are needed, such as bone holding forceps, reduction forceps and the like; however, the above-mentioned devices have the disadvantages of high cost, unreliable grip, large volume, and inflexibility in use. These disadvantages are particularly pronounced in cases of fractures of irregular bones, such as pubic fractures, iliac fractures, acetabular fractures, and the like. Kirschner wire (Kirschner wire) is used as an internal fixing material commonly used for trauma orthopedics, the length of the Kirschner wire is about 20cm, and the diameter of the Kirschner wire is between 0.5 and 3 mm; kirschner wires, which are typically electrically driven into the bone and through the bone fragments, are used to fix short fractures or avulsion fractures, and are also often used to temporarily fix bone fragments to maintain the fracture in place.
In some complex fracture cases, such as irregular bone fracture or deep fracture with narrow surgical approach, the ideal needle insertion direction of the kirschner wire is often blocked by soft tissues. In this case, the conventional surgical technique requires the surgeon to twist the kirschner wire by bare hands and simultaneously screw in the kirschner wire through the electric drill; in the case of large twists, surgeons often need to place sterile gauze between the kirschner wire and the glove in order to avoid entanglement of the worn sterile gloves with the rotating kirschner wire. The solution has the defects of unstable guide, easy shielding of the operation visual field and the like.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.
A side view of the orthopedic k-wire universal guide in a neutral position is shown in fig. 1. The guide handle 1 and the multi-section guide tubes 4, 5, 6, 7 together form a guide body. The control handle 2 and the resilient control rod 13 together form an L-shaped control. The guide body and the control member are connected by a U-shaped leaf spring 3. The end 14 of the elastic control rod 13 is hinged to the guide tube 7. The guide tubes 4, 5, 6 and 7 are connected with a certain interval and through hinges 8, 9 and 10. Loop loops 11, 12 are arranged below the central guide tubes 5, 6.
A side view of the handle of the orthopedic k-wire universal guide is shown in fig. 2. The guide handle 1 is rigidly connected with the guide tube 4, and the guide tube 4 and the guide tubes 5, 6, 7 are provided with guide holes 15 with the diameter of 2 mm.
A side view of the tail end of the orthopedic kirschner wire universal guide tube is shown in figure 3. The end 14 of the elastic control rod 13 is hinged to the guide tube 7.
A side partial cross-sectional view of the orthopedic k-wire gimbal guide in a neutral position is shown in fig. 4. Wherein the multi-section guide tubes 4, 5, 6 and 7 and the loop rings 11 and 12 are in cross section. It can be seen that the axes of the guide tubes are in a straight line in the neutral position, forming the guide holes 15. The elastic control rod 13 of the control device passes through the loop rings 11, 12, and the tail end 14 of the control device is hinged with the tail guide tube 7.
A side partial cross-sectional view of an orthopedic Kirschner wire in its neutral position with the Kirschner wire passing through the guide is shown in FIG. 5. In the neutral position, the Kirschner wire 16 is inserted through the guide hole 15, and the Kirschner wire 16 is not bent.
A side view of an orthopedic Kirschner wire gimbaled guide for changing the guide is shown in FIG. 6. The U-shaped leaf spring 3 is compressed when the control sub-handle 2 approaches the guide handle 1. Meanwhile, the elastic control rod 13 passes through the loop rings 11 and 12 to pull the guide tube 7, so that the gaps among the guide tubes 4, 5, 6 and 7 are changed, and the guide tubes 4, 5, 6 and 7 are deflected to one side of the elastic control rod 13. The flexible control rod 13 is flexible and can deflect with the guide tubes 4, 5, 6, 7.
The side part section view of the orthopedic Kirschner wire universal guide when changing the guide is shown in fig. 7. Wherein the multi-section guide tubes 4, 5, 6 and 7 and the loop rings 11 and 12 are in cross section. As the multi-section guide tubes 4, 5, 6, 7 deflect, the guide holes 15 also deflect.
The cross-sectional side view of the orthopedic Kirschner wire universal guide when the Kirschner wire universal guide changes the guide is shown in fig. 8 when the Kirschner wire passing through the guide is twisted. Wherein the multi-section guide tubes 4, 5, 6 and 7 and the loop rings 11 and 12 are in cross section. As the guide tubes 4, 5, 6, 7 and the guide hole 15 are deflected, the k-wire 16 passing through the guide hole 15 is also bent, thereby changing the screwing direction.
Particularly in the traumatic bone surgery, when the guider is in a neutral position, the axes of the multi-section guide tubes are on the same straight line; due to the strutting action of the U-shaped plate spring, the distance between the guide handle and the control sub-handle is far; when the kirschner wire passes through the multi-section guide tube, the kirschner wire is not bent, and the screwing direction is consistent with the axial direction of the kirschner wire, namely the multi-section guide tube. When the screwing direction of the kirschner wire needs to be changed in the operation, for example, in the external approach femoral shaft fracture incision reduction internal fixation operation, the fracture end needs to be temporarily fixed from the front to the back; in the anterior approach suprapubic fracture incision reduction internal fixation operation, the femoral arteriovenous sheath or femoral nerve needs to be avoided. At the moment, an operator can hold the guider handle and the control sub-handle by one hand, the U-shaped plate spring is compressed to enable the guider handle and the control sub-handle to be close to each other, the elastic control rod transmits the displacement of the control sub-handle to the other end of each section of guide tube, so that the interval between each section of guide tube is changed, namely, the interval of one side with a hinge is not changed, and the interval of one side without the hinge is narrowed; therefore, the multi-section guide tube can deflect to one side of the elastic control rod, and the kirschner wire positioned in the multi-section guide tube can be simultaneously twisted, so that the screwing direction of the kirschner wire is changed.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made in the above embodiments by those of ordinary skill in the art without departing from the principle and spirit of the present invention.
