Problems solved by technology

[0006] Since the bones are spliced ​​after cutting, although the cutting surface can be pre-designed, and the cutting position and cutting length on the bone can be guaranteed by using the osteotomy guide plate, the formed cutting surface is only a plane, and the bone itself Irregularities lead to the lack of reliable reference during the splicing process, and the bones after splicing are prone to misalignment and angle errors at the splicing site, such as Image 6 shown
Since this type of operation is mainly performed on the basis of the doctor's experience and relies heavily on the doctor's personal ability, the effect of the operation is not ideal and the reliability is low. Inexperienced doctors need long-term study and practice to perform the operation, which is very difficult. It is difficult to achieve theoretical accuracy, and there is a deviation from the original design. The impact of this deviation on the patient may not be obvious, but it may also be serious. In the end, the operation fails. If the patient is re-operated, it will bring harm to the patient. subsequent injury and suffering

Embodiment 1

[0032] like Figure 7 , Figure 8 Shown is one of the embodiments of the present invention. In this embodiment, the combined osteotomy guide plate 3 is provided with two guide plate units corresponding to the bone where the operation is performed, namely Figure 7 The upper guide plate 3-1 and the lower guide plate 3-2 in. The number of guide plate units depends on the needs of the operation, and more than two guide plate units can be provided.

[0033] The guide plate unit is provided with a guide groove 3-5 for inserting the osteotomy instrument, and is provided with a positioning device for fixing the guide plate on the bone, and the positioning device adopts the fixing hole 3-3. Along the guide groove 3-5, a straight section can be cut out on the bone, and an oblique section can also be cut out.

[0034] The guide plate unit is made separately or integrally, and is made separately in this embodiment.

[0035] The guide plate unit is provided with a combination device, ...

Embodiment 2

[0043] As the second embodiment of the present invention, compared with Embodiment 1, in this embodiment, the guide plate unit is also provided with a splicing surface (not shown in the figure), and the splicing surface can be set at a point where the angle decreases during the angle adjustment process. On the other hand, the combination device is composed of a splicing surface and the aforementioned hinged device. The splicing surface is planar or convex-concave. The purpose of setting the convex-concave shape is to increase the accuracy and firmness of the combination.

[0044] After the splicing surfaces are combined, the predetermined angle of orthopedic splicing is achieved. The positional relationship between the guide plate units is jointly defined by the splicing surfaces, the hinge device at the hinged part of the guide plate unit, and the aforementioned connection device, which improves the accuracy of the combination of the guide plate unit.

Embodiment 3

[0046] like Figure 11 , Figure 12 Shown is the third embodiment of the present invention. In this embodiment, the guide plate unit is made in one piece, that is, the guide plate unit is still fixedly connected together before assembly.

[0047] The combination device is composed of a splicing surface provided on the guide plate unit, specifically a side surface of the guide groove 4-5. The splicing surface is planar or convex-concave. The positional relationship between the guide plate units is defined.

[0048] The connection device adopts the pin shaft 4-7, and correspondingly, an adapted hole 4-6 is provided on the adjacent guide plate unit, and the axis of the pin shaft 4-7 is not perpendicular to the splicing surface 4-4. The purpose of this design is to prevent the upper guide plate from 4-1, the lower guide plate 4-2 twists at the splicing surface 4-4.

[0049] In order to facilitate the setting of holes 4-6, bosses can be set on the surface of the guide plate unit...

Abstract

The invention discloses a combined osteotomy guide. A plurality of guide units are arranged corresponding to a surgical part of a bone; the guide units are provided with guide slots for insertion of a bone cutting instrument; a positioning device for fixing the guide to the bone is arranged; the guide units are separately manufactured or manufactured in an integrated way; each guide unit is provided with a combination device; two adjacent guide units are combined through combination devices; a combination relationship is designed according to an operation plan for the bone; each guide unit is provided with a connecting device; after the guide units are combined, the guide units are fixedly connected through connecting devices. The combined osteotomy guide can be used for bone cutting and bone setting, is not required to be detached in the process, the bone joining angle is accurate, the height accords with a design plan, overdependence on personal capability of a doctor is avoided, and the surgical speed and quality are obviously improved.

Description

technical field [0001] The invention relates to a combined osteotomy operation guide plate, in particular to a guide plate used when operating or correcting deformed parts of human bones. Osteotomy and osteosynthesis can be performed through the guide plate, which belongs to the field of surgical instruments. Background technique [0002] Human bones have the ability to grow adaptively. Human bones with normal shape and structure ensure the appearance and actions of the human body, but diseases or accidents often cause distortions of human bones, such as the bending of the human tibia, such as figure 1 As shown, it directly causes the patient to have difficulty walking and standing. In the existing orthopedic medical methods, osteotomy can be performed on the deformed bone for correction and treatment. Excess bone tissue can be removed, and a piece of prosthesis can also be cut off to fill the bone. The final result is to make the bone length and The shape meets the prede...
