Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a novel multifunctional calibration device. Background Technology

[0002] Long bone fractures refer to fractures of the long bones in the human body, such as the femur, tibia, humerus, radius, and ulna. These fractures are often caused by falls, traffic accidents, sports activities, or direct impacts. Long bone fractures not only affect the structure and function of the bones but may also affect surrounding muscles, nerves, and blood vessels; therefore, timely and appropriate treatment is crucial.

[0003] During long bone surgery, guide devices and various taps are required. Taps are used to pre-drill holes to ensure the insertion of various instruments. Guide devices are used to guide the insertion path of various instruments. Existing guide devices can only guide and calibrate the tap or the inserted instrument individually.

[0004] Therefore, a device is designed to calibrate taps and insertion instruments of different specifications. Specifically, this device is a new type of multifunctional calibration instrument. Utility Model Content

[0005] To overcome the problems mentioned in the background art, the present invention adopts the following technical solution:

[0006] A novel multifunctional calibration instrument includes: a first plate having several through holes with different inner diameters for adjacent through holes; a second plate having several conical holes, the number of which is the same as the number of through holes, with the central axis of each conical hole corresponding to the central axis of each through hole; different sizes of insertion instruments can be fitted into through holes of different inner diameters, and after passing through a through hole, the insertion instrument can continue to move along the central axis of the through hole to enter the conical hole and abut against the inner wall of the conical hole. It also includes: a third plate connecting the first and second plates respectively, the connection method being either a fixed connection or a detachable connection, the third plate having one or more placement holes; and a fourth plate connecting the first and second plates respectively, the connection method being either a fixed connection or a detachable connection, the fourth plate having one or more placement holes, and both ends of the third and fourth plates having rounded corners. The connection points between the two ends of plate one and plates three and four are not the two ends of plates three and four, and the connection points between the two ends of plate two and plates three and four are not the two ends of plates three and four. The placement holes on plate three and plate four form an irregular polygon, therefore the polygon formed by the lines connecting the placement holes on plates three and four is not symmetrical about any one axis.

[0007] Furthermore, when plate one, plate two, plate three, and plate four are connected, they form a ring shape and constitute a cavity, which extends through the calibrator along the thickness direction of plate one. The cavity design facilitates the user's gripping and hanging of the calibrator, while also giving the calibrator higher structural stability.

[0008] Furthermore, both plate three and plate four have bent sections, which are symmetrically arranged on both sides of the cavity. The portions on both sides of the bent section of plate three are connected to one end of plate one and plate two, respectively, and the portions on both sides of the bent section of plate four are connected to one end of plate one and plate two, respectively. This helps to improve the structural strength of the calibrator.

[0009] Furthermore, it also includes an image calibration component, which can be visualized in the image calibration system, thereby characterizing the spatial position of the calibration component and its orientation at the corresponding position. The image calibration component is connected to the placement hole, and the number of image calibration components is the same as the number of placement holes. The central axes of adjacent placement holes may be parallel or non-parallel.

[0010] Furthermore, the outer wall of the plate is provided with a plurality of bosses, the number of which is the same as the number of through holes. Along the protrusion direction of the bosses, the sum of the thickness of the bosses and the thickness of the plate is greater than the inner diameter of the through hole, and the protrusion direction of the bosses is perpendicular to the axial direction of the through hole. The provision of the bosses allows the inner diameter of the through hole to be greater than the thickness of the plate, which is beneficial for providing more through holes on the plate, thereby accommodating more implanted instruments.

[0011] Furthermore, the outer wall of the second plate is provided with a plurality of second bosses, the number of which is the same as the number of conical holes; the protrusion direction of the second bosses is the same as that of the first boss, and the thickness of the second bosses is the same as that of the first boss. The second bosses and the first bosses are arranged opposite each other on both sides of the cavity, and the inner diameter of the through hole is the same as the maximum inner diameter of the corresponding conical hole, so that the instrument inserted into the through hole can fit into the corresponding conical hole and abut against the inner wall of the conical hole.

[0012] Furthermore, it also includes a tap positioning component, which is connected to the second plate. The tap positioning component has a tapered groove, the opening direction of which is different from the opening direction of the tapered hole. When the tap positioning component is connected to the second connecting plate, the relative positional relationship between the tapered groove and each image calibration component is fixed. Therefore, when the tap bit abuts against the tapered groove, the tap bit can be calibrated by the image calibration system.

[0013] Furthermore, the tap positioning component is provided with a connecting post, and the plate has two openings with connecting holes. When the tap positioning component enters the connecting hole along the axial direction of the connecting post, the central axis of the connecting post coincides with the central axis of the connecting hole.

[0014] Furthermore, the side edges of plate one, plate two, plate three, and plate four are all chamfered to prevent cuts to the user when gripping. The connection between plate one and plate three is rounded, and the connection between plate one and plate four is chamfered; the connection between plate two and plate three is rounded, and the connection between plate two and plate four is chamfered. The rounded corners help to reduce the stress on the internal structure of the calibrator when subjected to external impact.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting various through holes and tapered holes with different inner diameters, the calibrator can connect to surgical instruments for long bones of different specifications; by setting image calibration components and tap calibration components with tapered grooves, the calibrator can also calibrate taps of different specifications.

[0017] 2. Plate 1 can form an I-shaped structure with Plate 2 and Plate 3, and Plate 2 can also form an I-shaped structure with Plate 2 and Plate 3. Furthermore, a cavity can be formed between the two I-shaped structures. This design improves the overall structural strength of the calibrator while ensuring the lightweight structure, effectively reducing manufacturing costs, and thus has excellent practical effects.

[0024] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] A new type of multifunctional calibration instrument, such as Figure 1-4As shown, the system includes: a plate 1 with several through holes 11, the inner diameters of adjacent through holes 11 being different; a plate 2 with several conical holes 21, the number of conical holes 21 being the same as the number of through holes 11, the central axis of the conical holes 21 corresponding to the central axis of the through holes 11; different sizes of insertion devices can be fitted into the through holes 11 with different inner diameters, and after passing through the through holes 11, the insertion device can continue to move along the central axis of the through holes 11 to enter the conical holes 21 and abut against the inner wall of the conical holes 21. The system also includes: a plate 3 connecting plate 1 and plate 2 respectively, the connection method being either a fixed connection or a detachable connection, plate 3 having one or more placement holes 31; and a plate 4 connecting plate 1 and plate 2 respectively, the connection method being either a fixed connection or a detachable connection, plate 4 having one or more placement holes 31, and both ends of plate 3 and plate 4 having rounded corners. The connection points between the two ends of plate 1 and plates 3 and 4 are not the two ends of plates 3 and 4, respectively. Similarly, the connection points between the two ends of plate 2 and plates 3 and 4 are not the two ends of plates 3 and 4. This allows plates 1, 3, and 4 to be connected in an I-shape, and plates 2, 3, and 4 to also be connected in an I-shape. This prevents plate 1 (with through holes 11) and plate 2 (with tapered holes 21) from colliding with the ambient surface when the multi-functional calibrator comes into contact with the environment. The placement holes 31 on plate 3 and 4 form an irregular polygon; therefore, the polygon formed by the lines connecting the placement holes 31 on plates 3 and 4 is not symmetrical about any one axis. When the calibrator is flipped, even if the shapes of plate 3 and plate 4 are the same, the front and back of the calibrator can be distinguished according to the shape of the line connecting the placement holes 31. When the calibrator is connected to the image calibration component 5, the front and back of the calibrator can also be determined according to the image of the image calibration component 5 in the image system, which helps to improve the accuracy of determining the spatial position of the calibrator.

[0026] In some embodiments of this application, such as Figure 1-4 As shown, when plate 1, plate 2, plate 3, and plate 4 are connected, they form a ring and constitute a cavity 12. The cavity 12 extends through the calibrator along the thickness direction of plate 1. The cavity 12 facilitates the user's gripping and hanging of the calibrator, while also giving the calibrator higher structural stability.

[0027] In some embodiments of this application, such as Figure 1-4As shown, both plate 3 and plate 4 have bent sections 32, which are symmetrically arranged on both sides of the cavity 12. The portions on both sides of the bent section 32 of plate 3 are connected to one end of plate 1 and plate 2, respectively, and the portions on both sides of the bent section 32 of plate 4 are connected to one end of plate 1 and plate 2, respectively. This helps to improve the structural strength of the calibrator.

[0028] In some embodiments of this application, such as Figure 1-4 As shown, it also includes an image calibration component 5, which can display an image in the image calibration system, thereby characterizing the spatial position of the calibration component and its orientation at the corresponding position. The image calibration component 5 is connected to the placement hole 31, and the number of image calibration components 5 is the same as the number of placement holes 31. The central axes of adjacent placement holes 31 are parallel or non-parallel.

[0029] In some embodiments of this application, such as Figure 1-4 As shown, the outer wall of plate 1 has several bosses 13, the number of which is the same as the number of through holes 11. Along the protruding direction of the bosses 13, the sum of the thickness of the bosses 13 and the thickness of plate 1 is greater than the inner diameter of the through hole 11, and the protruding direction of the bosses 13 is perpendicular to the axial direction of the through hole 11. The bosses 13 allow the inner diameter of the through hole 11 to be greater than the thickness of plate 1, which is beneficial for setting more through holes 11 on plate 1, thereby accommodating more implanted instruments. Furthermore, the bosses 13 extend outward from the outer wall of plate 1, which allows a gap to be formed between the outer wall of plate 1 and the surface on which the calibrator is placed when the calibrator is placed on the surface of the bosses 13 facing the environment. This facilitates the user's gripping of the calibrator through the gap and cavity 12.

[0030] In some embodiments of this application, such as Figure 1-4 As shown, the outer wall of plate 2 has several bosses 23, the number of which is the same as the number of conical holes 21. The protrusion direction of bosses 23 is the same as that of bosses 13, and the thickness of bosses 23 is the same as that of bosses 13. Bosses 23 and bosses 13 are positioned opposite each other on both sides of the cavity 12. The inner diameter of the through hole 11 is the same as the maximum inner diameter of the corresponding conical hole 21, so that the instrument inserted into the through hole 11 can fit into the corresponding conical hole 21 and abut against the inner wall of the conical hole 21. Since the positional relationship between the conical hole 21 and each image calibration component 5 is fixed, when the user completes the calibration of each image calibration component 5 of the calibrator through the image calibration system, the spatial position of each conical hole 21 can be deduced through the spatial coordinate relationship, and thus the spatial coordinates of the other end of the inserted instrument, which abuts against the conical hole 21 and has a defined length, can be obtained.

[0031] In some embodiments of this application, such as Figure 1-4 As shown, it also includes a tap positioning component 6, which is connected to the second plate 2. The tap positioning component 6 has a tapered groove 61, and the opening direction of the tapered groove 61 is different from the opening direction of the tapered hole 21. Since the opening of the tapered hole 21 faces the through hole 11, if the opening direction of the tapered groove 61 is the same as the opening direction of the tapered hole 21, the tap can only be placed in the cavity 12, which limits the length of the tap that can be calibrated. Therefore, the opening direction of the tapered groove 61 of the tap positioning component 6 cannot be the same as the opening direction of the tapered hole 21. When the tap positioning component 6 is connected to the second connecting plate, the relative positional relationship between the tapered groove 61 and each image calibration component 5 is fixed. Therefore, when the tap bit abuts against the tapered groove 61, the tap bit can be calibrated by the image calibration system.

[0032] In some embodiments of this application, such as Figure 1-4 As shown, the tap positioning component 6 is provided with a connecting post 62, and the plate part 2 is provided with a connecting hole 22. When the tap positioning component 6 enters the connecting hole 22 along the axial direction of the connecting post 62, the central axis of the connecting post 62 coincides with the central axis of the connecting hole 22.

[0033] In some embodiments of this application, such as Figure 1-4 As shown, the side edges of parts 1, 2, 3, and 4 are all chamfered to prevent cuts to the user when gripping. The connection between parts 1 and 3 has rounded corners, and the connection between parts 1 and 4 has a chamfer; the connection between parts 2 and 3 has rounded corners, and the connection between parts 2 and 4 has a chamfer. The rounded corners help to reduce the stress on the internal structure of the calibrator when subjected to external impacts.
