Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a device combining a supporting device and a navigation device, and a navigation device with the device. Background Art

[0002] When performing surgical navigation, it is first necessary to determine the surgical direction. After the surgical direction is determined, a navigation device with a reference frame is held hand-held to perform a guidance operation. In the guidance operation, the surgeon holds the navigation device with a reference frame installed to perform the guidance operation under the navigation system. However, the hand-held method will inevitably cause shaking during the operation, resulting in deviations in the guidance direction. Therefore, in order to ensure that the navigation device with a reference frame is always in a relatively stable state during the guidance operation, in current clinical practice, the navigation device with a reference frame is used in combination with a multi-joint support device (reference patent document CN219331980U) installed on one side of the bed. In this way, during the guidance operation, the navigation device with a reference frame is moved on the basis of the multi-joint support device, thereby allowing the navigation device to maintain a relatively stable state during the movement.

[0003] However, how to effectively connect the surgical navigation instrument with the supporting instrument so that the navigation instrument can maintain stability when it moves with the support instrument is an urgent problem to be solved.

[0004] In view of the above problems, the present invention provides a device combining a supporting device and a navigation device and a navigation device with the device. Summary of the invention

[0005] In order to overcome the problems raised in the background technology, the present invention adopts the following technical solutions:

[0006] A device combining a supporting device and a navigation device and a navigation device with the device, comprising:

[0007] A main body having a first connection portion for connecting to a navigation device;

[0008] A locking member, disposed on one side of the main member and rotatably connected to the main member, wherein the locking member has a locking end, and when the locking member rotates, the locking end approaches the first connecting portion and forms a connection relationship with the navigation device, so that the navigation device is fixed in the height direction of the main member;

[0009] An elastic member, one end of which is connected to the main member, and the other end of which is connected to the locking member; wherein, after the locking end is away from the first connecting portion, the elastic member can drive the locking member to rotate and make the locking end approach the first connecting portion.

[0010] In this embodiment, it also includes: a positioning member, which is connected to the locking member. The positioning member can move toward the main member and form an abutment state with the main member, wherein in the abutment state, the position of the locking member is fixed.

[0011] Furthermore, the positioning member includes: an operating portion and a rod portion that are fixedly connected or integrally formed, and an outer wall of the rod portion is formed with an external thread, wherein the locking member has a threaded hole, and the rod portion is screwed into the threaded hole through the external thread.

[0017] In some embodiments of the present application, the elastic member includes: a spring, wherein one end of the spring is connected to the main body, and the other end of the spring is connected to the locking member. When the locking member is not subjected to force, the spring is in a normally open state, so that the position of the locking end of the locking member remains unchanged. When the locking member is subjected to force, the spring is compressed by the pressure of the locking member. When the locking member stops being subjected to force, the spring naturally opens, thereby causing the locking end of the locking member to approach the direction of the first connecting portion.

[0018] A navigation device, comprising: a connecting piece, comprising a connecting ring, the connecting ring having a notch; and

[0019] The adjusting ring is connected to the connecting ring, and an angle is formed between the axis of the adjusting ring and the axis of the connecting ring, wherein the adjusting ring comprises a limiting structure and an adjusting structure; the limiting structure and the adjusting structure are both arranged on the side wall of the connecting ring, and the notch is located between the limiting structure and the adjusting structure; a through hole is arranged inside the limiting structure;

[0044] The technical solutions in the embodiments of the present invention are described clearly and completely below through specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Figure 1 —2 shows the main technical content of this embodiment. This specific embodiment provides a device for combining a supporting device and a navigation device, which includes:

[0046] A main body having a first connecting portion 30 for connecting an operating device;

[0047] The locking member 60 is disposed on one side of the main member and is rotatably connected to the main member, wherein the locking member 60 has a locking end 602. When the locking member 60 moves in the first movement direction, the locking end 602 approaches the first connection portion 30 and forms a connection relationship with the operating device, so that the operating device is fixed in the height direction of the main member;

[0048] The elastic member has one end connected to the main member and the other end connected to the locking member 60 ; wherein, after the locking end is away from the first connecting portion 30 , the elastic member can drive the locking member 60 to rotate and make the locking end 602 approach the first connecting portion 30 .

[0049] More specifically, the main body further comprises a second connection portion 40 for connecting to a supporting device, wherein the second connection portion 40 is located on an end of the main body away from the first connection portion 30 .

[0050] When in use, the supporting device is fixed on one side of the bed, and the supporting device is connected to the second connecting part 40 of the main part. Then, force is applied to the locking member 60 to rotate the locking member 60 relative to the main part, so that the locking end 602 is away from the first connecting part 30, so that the locking member 60 is in an open state, and then the operating device with the reference frame is connected to the first connecting part 30, and the locking member 60 is released. The locking member 60 rotates under the action of the elastic member. At this time, the locking end 602 moves toward the first connecting part 30, and the locking end 602 of the locking member 60 forms a connection relationship with the operating device, thereby fixing the operating device at the first connecting part 30, thereby connecting the operating device with the supporting device.

[0051] refer to Figure 1 and Figure 5 In the present embodiment, the first connecting portion 30 comprises: a limiting axis 301 and a connecting axis 302, wherein there is a distance between the limiting axis 301 and the connecting axis 302, more preferably, the limiting axis 301 and the connecting axis 302 are parallel to each other, and the limiting axis 301 and the connecting axis 302 are arranged in an array in the length direction of the main body; when in use, the operating instrument is plugged into and matched with the limiting axis 301 and the connecting axis 302, and after the plugging and matching, the locking end 602 of the locking member 60 is always against the outer wall of the operating instrument under the action of the elastic member, so that the operating instrument is fixed, in addition, the setting of the limiting axis 301 and the connecting axis 302 can also prevent the operating instrument from rotating relative to the limiting axis 301 and the connecting axis 302, and then when the operating instrument is moved under the navigation system for guidance operation, the operating instrument will not rotate or shake, thereby avoiding deviation in its guiding direction.

[0052] As an alternative (not shown), the first connecting portion 30 may also include a rectangular section arranged at one end of the main body. Similarly, the operating instrument and the rectangular section are in a plug-in relationship. When in use, the rectangular section can be inserted into the operating instrument to form a connection relationship between the operating instrument and the supporting instrument; and the rectangular section can be used to prevent the operating instrument from rotating during use.

[0053] refer to Figure 3 In the present embodiment, the main body also has a groove 202 , which is formed on one side where the locking member 60 is located, wherein a portion of the locking member 60 extends into the groove 202 .

[0054] refer to Figure 2—3 Specifically, the locking member 60 has a connecting arm 601, and the connecting arm 601 is located in the groove 202, wherein the connecting arm 601 has a first rotating shaft and a second rotating shaft that are mirror-arranged, and the groove 202 has a first connecting hole and a second connecting hole that are mirror-arranged to each other, the first rotating shaft is arranged in the first connecting hole, and the second rotating shaft is arranged in the second connecting hole, wherein the locking member 60 rotates with the axis of the first connecting hole and the second connecting hole as the center of the circle, so that the locking end 602 approaches or moves away from the first connecting portion 30, thereby realizing the conversion of the locking member 60 between the open state and the locked state, thereby completing the connection with the operating device.

[0055] refer to Figure 3 and Figure 6 —7. The locking member 60 also has a force-bearing end 603 opposite to the locking end 602. When in use, by pressing the force-bearing end 603, the force-bearing end 603 approaches the main body. At this time, the locking member 60 rotates in the first rotation direction, so that the locking end 602 is away from the first connecting part 30, thereby making the locking member 60 present an open state. After stopping the force on the force-bearing end 603, the force-bearing end 603 is away from the main body under the action of the elastic member. At this time, the locking member 60 rotates in the second rotation direction, and the locking end 602 approaches the first connecting part 30, thereby making the locking member 60 present a locked state.

[0056] refer to Figure 2 —3 and Figure 6 —7. In the present embodiment, the elastic member comprises: a spring 70, one end of the spring 70 is connected to the main body, and the other end of the spring 70 is connected to the locking member 60. When the locking member 60 is not subjected to force, the spring 70 is in a normally opened state, so that the position of the locking end 602 of the locking member 60 remains unchanged. When the locking member 60 is subjected to force, the force-bearing end 603 of the locking member 60 is forced to approach the main body, and the locking end 602 of the locking member 60 gradually moves away from the first connecting portion 30. At this time, the spring 70 is compressed by the pressure of the locking member 60. When the locking member 60 stops being subjected to force, the spring 70 naturally opens, thereby causing the locking end 602 of the locking member 60 to approach the first connecting portion 30.

[0057] More specifically, the spring 70 is at least partially located in the groove 202, wherein the main body also has a first limit pin 701, and the locking member 60 also has a second limit pin 702. The two ends of the spring 70 are separately arranged around the first limit pin 701 and the second limit pin 702. The first limit pin 701 is located in the groove 202. Under this arrangement, the spring 70 will not disengage from the groove 202, so that the locking member 60 is maintained in a locked state under the action of the spring 70.

[0058] As an alternative (not shown), the elastic member can be configured as: an elastic sheet, the elastic sheet comprising a first elastic segment, a second elastic segment and a bending portion connecting the first elastic segment with the second elastic segment, wherein there is an angle between the first elastic segment and the second elastic segment, the first elastic segment is connected to the locking member 60, and the second elastic segment is fixed in the groove 202. When in use, force is applied to the force-bearing end 603 of the locking member 60 so that the force-bearing end 603 approaches the main body. At this time, the bending portion is deformed, and the angle between the first elastic segment and the second elastic segment is reduced, so that the first elastic segment and the second elastic segment are closer to each other. After the force on the force-bearing end 603 stops, the bending section is reset, so that the force-bearing end 603 is away from the main body.

[0059] As an alternative (not shown), the elastic sheet can also be set to an arc shape. When the force-bearing end 603 approaches the main body, the curvature of the arc-shaped elastic sheet gradually increases. After the force on the force-bearing end 603 stops, the curvature of the arc-shaped elastic sheet returns to its original size.

[0060] To avoid accidentally touching the locking member 60 during the guiding process of the mobile operating device; Figure 2 —10. In the present embodiment, it further includes: a positioning member 80, which is connected to the locking member 60. The positioning member 80 can move toward the main member and form an abutting state with the main member, wherein in the abutting state, the position of the locking member 60 is fixed. Specifically, the positioning member 80 includes: an operating portion 801 and a rod portion 802 that are fixedly connected or integrally formed, and an outer wall of the rod portion 802 is formed with an external thread, wherein the locking member 60 has a threaded hole, and the rod portion 802 is screwed into the threaded hole through the external thread, and the positioning member 80 is screwed into the groove 202 through the external thread until one end of the rod portion 802 abuts against the groove wall of the groove 202, so that the positioning member 80 cannot rotate relative to the main member, thereby keeping the locking member 60 in a locked state. When the operating instrument is connected to the first After the first connection part 30 is connected, the operating instrument is fixed by the first connection part 30 and the locking end 602 of the locking member 60. At this time, by screwing the operating part 801, one end of the rod 802 is gradually moved closer to the main body until it abuts against the main body. At this time, the rod 802 maintains its position under the engagement of the external thread and the threaded hole. Under the action of the positioning member 80, the positional relationship between the locking end 602 and the first connection part 30 (or the operating instrument) remains unchanged, and the locking end 602 abuts against the operating instrument. At the same time, the operating instrument reacts to the locking end 602, thereby preventing the locking member 60 from rotating after being subjected to force, thereby avoiding the operator (operator) from accidentally touching the locking member 60 during the process of moving the operating instrument for guidance, causing the operating instrument to detach from the first connection part 30.

[0061] As can be understood by those skilled in the art, in this embodiment, no elastic member is provided, and only a positioning bolt connected to the locking member 60 is provided, wherein the locking member 60 is always in an open state. After the operating instrument is connected to the first connecting part 30, the positioning bolt is rotated so that one end of the positioning bolt gradually approaches the main member until it abuts against the main member, thereby locking the operating instrument.

[0062] refer to Figure 2 —3. In the present embodiment, the main body is composed of a first main body portion 10 and a second main body portion 20. The first main body portion 10 is provided with at least two first threaded holes 101, and the second main body portion 20 is provided with at least two second threaded holes. After the first main body portion 10 and the second main body portion 20 are connected, each first threaded hole 101 corresponds to a second threaded hole, and a bolt is used to screw from the first threaded hole 101 into the second threaded hole, so that the first main body portion 10 and the second main body portion 20 always remain in a connected state.

[0063] refer to Figure 2 —5. In the present embodiment, the second connection part 40 includes: a first card slot provided on the first main body part 10, and a second card slot provided on the second main body part 20. After the first main body part 10 and the second main body part 20 are combined, the first card slot and the second card slot form the second connection part 40. When in use, one end of the supporting device is respectively placed in the first card slot and the second card slot, and then force is applied to the first main body part 10 and the second main body part 20 respectively, so that the first part and the second part are close to each other until the two are connected. At this time, the end of the supporting device is located in the second connection part 40 formed by the first card slot and the second card slot, and then a bolt is used to screw in from the first threaded hole 101 or the second threaded hole until the bolt is screwed into the other threaded hole, thereby realizing the connection relationship between the main body and the supporting device.

[0064] refer to Figure 4 —5. In the present embodiment, it also includes: a base 50, wherein the base 50 is detachably configured in the second connecting part 40, and the base 50 includes: a connecting plate and a fixed shaft, wherein the connecting plate is configured at one end of the fixed shaft, and the connecting plate and the fixed shaft are integrally connected. Specifically, the second connecting part 40 also has a circular hole, and the diameter of the circular hole is the same as the diameter of the fixed shaft. When in use, the connecting plate is placed in the connecting part formed by the first card slot and the second card slot, and the fixed shaft extends out of the circular hole. When in use, a connection relationship is formed with the supporting device through the fixed shaft.

[0065] In addition, as can be understood by people in this field, the supporting device is installed on the operating bed when in use, and is not a sterile device. The operating device is a sterile surgical device. This device combines the two. In order to protect the operating device from contamination, a sterile plastic sleeve is used on the outside of the supporting device when in use, so that the operating device is always in a sterile state when in use.

[0066] The method of using this embodiment is as follows:

[0067] 1. Fix the supporting device on one side of the bed, place one end of the supporting device between the first main body 10 and the second main body 20, and connect the first main body 10 and the second main body 20, thereby connecting the first main body 10 and the second main body 20 to one end of the supporting device fixed on one side of the bed through the second connecting part 40.

[0068] 2. Apply force to the force-bearing end 603 of the locking member 60 so that the locking end 602 moves away from the first connecting portion 30 in a direction away from the second main body portion 20 , thereby converting the locking member 60 to an open state.

[0069] 3. Connect the operating instrument with the reference frame to the first connecting part 30, loosen the locking piece 60, and the locking piece 60 is transformed from the open state to the locked state under the action of the elastic member, that is, the locking piece 60 rotates so that the locking end 602 moves toward the direction of the first connecting part 30. At this time, the locking end 602 of the locking piece 60 forms an abutment relationship with the operating instrument.

[0070] 4. Tighten the positioning bolt so that one end of the positioning bolt gradually approaches the second main body 20 until it abuts against the second main body 20. The positioning bolt maintains its position while being engaged with the threaded hole. Under the action of the positioning bolt, the locking end 602 always approaches the first connecting portion 30 (or the operating device). At the same time, the operating device reacts to the locking end 602, so that the locking member 60 will not rotate after being subjected to force.

[0071] Example 2

[0072] like Fig.11 —13 and Fig.16 , a navigation device as shown, comprising: the device of combining a supporting device and a navigation device as described in Example 1, further comprising:

[0073] A connecting member 2, comprising a connecting ring 22, wherein the connecting ring 22 has a notch; and

[0074] The adjusting ring 21 is connected to the connecting ring 22, and there is an angle between the axis of the adjusting ring 21 and the axis of the connecting ring 22, wherein the adjusting ring 21 includes a limiting structure and an adjusting structure; the limiting structure and the adjusting structure are both arranged on the side wall of the connecting ring 22, and the notch is located between the limiting structure and the adjusting structure; a through hole is arranged inside the limiting structure;

[0075] The handle 1 has a connecting end 11; the connecting end 11 passes through a through hole and is threadedly connected to the adjusting structure; wherein the handle 1 is constructed to drive the adjusting structure to move toward the position of the limiting structure when rotating, and reduce the width of the gap; and to drive the adjusting structure away from the limiting structure when rotating in the opposite direction.

[0076] The handle 1 has a joint portion, and the handle 1 is connected to the first connecting portion 30 via the joint portion, and is fixed above the main body by the locking end 602 in the height direction of the main body.

[0077] Reference Image Figure 1 and 10 Specifically, the joint portion has a first hole for inserting the limiting shaft 301, a second hole for inserting the connecting shaft 302, and a limiting groove formed on the outer wall of the joint portion. When in use, the limiting shaft 301 and the connecting shaft 302 are respectively inserted into the first hole and the second hole, and the locking end 602 of the locking piece 60 is inserted into the limiting groove; thereby, the handle 1 and the first connecting portion 30 are connected.

[0078] refer to Fig.12 —13, more specifically, the handle 1 also includes a limiting portion and a holding end 13 which are fixedly connected to the connecting end 11 in sequence; rotating the handle 1 can release the positional relationship between the handle 1 and the cannula instrument; after adjusting the posture of the handle 1 to a suitable state, the handle 1 is rotated in the opposite direction to limit the positional relationship between the handle 1 and the cannula instrument; it is convenient, fast and time-saving, and there is no need to use special tools unrelated to the operation, thereby reducing the risk of infection.

[0079] The principle of the connection member 2 limiting the positional relationship between the handle 1 and the positioning sleeve 4 is as follows:

[0080] refer to Fig.11 —13 and Fig.16 After inserting the handle 1 into the adjusting ring 21, the handle 1 is rotated, and the limiting part is stuck on the limiting structure. The screw thread on the handle 1 is rotated to drive the adjusting structure to move in the direction of the limiting structure, thereby reducing the distance between the limiting structure and the adjusting structure, and reducing the width of the notch on the side wall of the connecting ring 22, so that the connecting ring 22 is elastically deformed, and the connecting ring 22 is fixed to the outside of the positioning sleeve 4. At the same time, the handle 1 and the connecting member 2 are connected by threads, thereby locking the positional relationship between the handle 1 and the positioning sleeve.

[0081] At this time, the connecting ring 22 is compressed, and the connecting ring 22 itself will generate an elastic force to restore its original shape. This elastic force will act on the limiting structure and the adjusting structure respectively, driving the distance between the limiting structure and the adjusting structure to increase. At this time, the limiting part is stuck on the limiting structure, and the adjusting structure is threadedly connected to the connecting end 11. After the elastic force is transmitted to the limiting structure and the adjusting structure, it becomes a thrust along the axial direction of the limiting structure and the adjusting structure, but the force to release the connection relationship between the adjusting structure and the connecting end 11 is a rotational force. In the current situation, the thrust along the straight line direction cannot be converted into a rotational force. Therefore, the connecting ring 22 itself will generate an elastic force to restore its original shape and cannot release its own lock, and a self-locking is formed between the handle 1, the connector 2, and the positioning sleeve 4.

[0082] In some embodiments of the present application, Fig.12 , Fig.16 As shown, it also includes: a positioning sleeve 4, the positioning sleeve 4 is in a sleeve-connected relationship with the connecting ring 22, and the positioning sleeve 4 is at least partially located in the connecting ring 22; the inner tube 5 is detachably connected to the interior of the positioning sleeve 4; at least two types of inner tubes 5 are provided, and different inner tubes 5 have the same outer diameter and different inner diameters. The purpose of this design is to make the same type of positioning sleeve 4 adapt to more types of implants such as intramedullary nails and screws. After the positioning sleeve 4 is placed in a suitable position, implants of different types can be delivered into the patient's body through the positioning sleeve 4 by simply replacing different inner tubes 5.

[0083] The angle between the axis of the adjusting ring 21 and the axis of the connecting ring 22 is 60°-120°, so as to ensure that the wrist is substantially parallel to the sleeve direction during the operation, so that the doctor can fine-tune the position of the sleeve more flexibly.

[0084] In the specific example of this application, Fig.12 , Fig.13 as well as Fig.16 As shown, the axis of the connecting end 11, the limiting part and the holding end 13 are the same. When the handle 1 is rotated, the posture of the handle 1 does not change. The position relationship of the locking handle 1, the connecting member 2 and the positioning sleeve 4 is front and back, and the axis of the handle 1 remains stationary.

[0085] If there is an angle between the axis of the connecting end 11 and the axis of the holding end 13, when the handle 1 is rotated to tighten the distance between the limiting structure and the adjustment structure, the holding end 13 will rotate with the axis of the connecting end 11 as the axis. In most cases, when the connecting end 11 is tightened, the holding end 13 will be out of the original position, so that the posture of the handle 1 is not the posture before locking. Although this design can achieve the purpose of adjusting the positional relationship between the handle 1 and the positioning sleeve, the posture of the handle 1 changes before and after locking, which increases the difficulty of adjusting the handle 1.

[0086] In some examples of this application, such as Fig.12 , Fig.14 As shown, the positioning sleeve 4 also includes a sleeve body 41 and a large end 42. One end of the sleeve body 41 is fixedly connected to the large end 42, and the other end is fixedly connected to the positioning end 43. The connecting member 2 and the calibration frame 3 are both fixed to the outside of the sleeve body 41. The interior of the positioning sleeve 4 is provided with uniform through holes.

[0087] In some examples of this application, such as Fig.12 and Fig.14 As shown in FIG. 15 , the positioning sleeve 4 has a positioning end 43; the positioning end 43 includes a double-pointed structure; the double-pointed structure includes two spikes 431 arranged in a circle along the axis of the positioning sleeve 4. When the positioning sleeve 4 deviates from the predetermined position, the positioning sleeve 4 can be rotated by holding the handle 1 and taking one of the spikes 431 as the center of the circle, so as to adjust the position of the other spike 431. This can be repeated to achieve fine adjustment of the distal end position of the positioning sleeve 4, so that the positioning sleeve 4 can quickly reach the predetermined position.

[0088] Preferably, the positioning end 43 further includes a buffer plane 432; the spike 431 is arranged on the buffer plane 432. The rear end of the spike 431 is provided with a buffer plane 432, and the buffer plane 432 is perpendicular to the axial direction of the positioning sleeve 4 to prevent the spike 431 from being excessively inserted into the bone tissue and causing unnecessary damage; at the same time, the buffer plane 432 limits the length of the spike 431 inserted into the bone tissue, so as to determine the distance between the calibration frame 3 and the surface of the bone tissue, and facilitate the control of the nail placement depth.

[0089] Furthermore, the positioning end 43 also includes an indicating slope 433; there are angles between different indicating slopes 433; and the extended intersection area of ​​the indicating slope 433 overlaps with the spike 431. During the operation, the doctor can observe the position of the spike 431 and fine-tune the distal position of the positioning sleeve 4.

[0090] In addition, positioning sleeves of different lengths are provided to cope with surgeries at different locations.

[0091] The method of using this embodiment is as follows:

[0092] 1. Fix the connection assembly on the positioning sleeve 4;

[0093] 2. Use the first adjustment component and the second adjustment component to adjust the positional relationship between the connection component and the calibration structure;

[0094] 3. Sleeve the connecting ring 22 onto the outside of the positioning sleeve 4, and thread the connecting end 11 of the handle 1 through the limiting structure and then connect it to the adjusting structure;

[0095] 4. Adjust the handle 1 to a suitable posture, and then rotate the handle 1 to lock the position relationship between the handle 1 and the positioning sleeve 4;

[0096] 5. Insert the positioning sleeve 4 into the patient's body, and use the double-pointed structure to fine-tune the position of the positioning sleeve 4;

[0097] 6. Insert a suitable inner tube 5, and insert the implant into the patient's body through the hole of the inner tube 5. During the operation, replace the inner tube 5 of different types according to the size of the implant.

[0098] The above embodiments are only used to understand the present invention. It should be noted that, for those skilled in the art, several improvements can be made to the present invention without departing from the principles of the present invention, and these improvements will also fall within the scope of protection of the claims of the present invention.
