[0002] In the prior art, no matter the multi-segment holding structure fixation mode such as the rib bone fracture plate in CN203777033U or the attached fixation mode such as the degradable absorbable magnesium alloy rib fracture fixation plate and fixation apparatus system in CN202010802000.9, the length of the rib fixation apparatus is relatively long, and it is difficult to carry out minimally invasive surgery, so the operation window is large, and the damage to the patient is large.

[0003] If a rib fixation apparatus in a rotating mode is used to fix the rib, the technical problem still exists, that is, how to set appropriate operating apparatus.

[0004] The utility model provides a self-locking rib fracture fixator auxiliary operating apparatus aiming at the above technical problem. UTILITY MODEL CONTENTS

[0005] The fixation apparatus required to control the operation of the operating apparatus of the utility model is an operating apparatus of a rib fixation apparatus which is constructed by the idea of connecting part one and connecting part two with two groups of fixed hook groups and is capable of rotating adjustment and locking the fixed position at the same time during rotating adjustment.

[0006] The specific technical solution of the fixation device is: a fracture fixation device for rotating and clamping ribs under laparoscopic surgery, which includes: 4 clamping and fixing hooks; 2 cross-arranged connecting parts, the two connecting parts are respectively connecting part one and connecting part two; a clamping and fixing hook is provided at both ends of each connecting part, and the cross-arrangement of the two connecting parts makes the four clamping and fixing hooks constitute two pairs of fixing hook groups with hooks facing opposite directions for clamping and fixing ribs, and the two clamping and fixing hooks of each group of fixing hooks are one at one end of the connecting part and the other at the other end of the connecting part; it also includes a rotation locking part, which is provided at the intersection position between the two connecting parts, and the rotation adjustment angle between the two connecting parts is achieved by rotating the locking part. The rotation locking part includes a cylindrical protrusion structure, which is provided in the middle of the connecting part one and is integrally connected to the connecting part one; with The circular ring structure of the cylindrical hole groove is arranged in the middle of the connecting part two and is integrally connected to the connecting part two, and the cylindrical protruding structure extends into the cylindrical hole groove to realize the cross combination of the connecting part one and the connecting part two; and a locking protrusion and a plurality of locking teeth arranged in a circumferential array, the locking protrusion is arranged on the outer wall of the cylindrical protruding structure or the inner wall of the cylindrical hole groove, and the corresponding locking teeth are arranged on the inner wall of the cylindrical hole groove or the outer wall of the cylindrical protruding structure. The locking protrusion and the locking teeth cooperate to only allow the cylindrical protruding structure to rotate in one direction in the cylindrical hole groove and will not reverse. In this way, the connecting part one and the connecting part two rotate in a single direction with the rotating locking part. The rotation in a single direction makes the two clamping fixing hooks of each group of fixing hooks relatively close to each other, and at the same time the locking protrusion enters the position between the corresponding two locking teeth, locking the rotation action of the connecting part one and the connecting part two.

[0007] Because the fixation devices in the prior art are mostly small in size and are performed under minimally invasive conditions, the rotation of the connecting part 1 and the connecting part 2 cannot be completed by fingers, and a special operating device is required to complete it. In this way, two mutually cooperating operating structures are required to cooperate with each other to complete the combination of the connecting part 1 and the connecting part. After the combination, the connecting part 1 and the connecting part 2 are controlled to rotate relative to each other to complete the operation of the fixation device, so that the fixation device changes from the entry state to the fixed state. The operating device includes:

[0008] The operating structure 1 is a sleeve structure, the first end of which is connected to the ring structure of the connecting part 1 on the fixing device, the middle part is the sleeve part, which is used to introduce the operating structure 1 into the body, and the second end is the gripping structure 1 for gripping operation;

[0009] The second operating structure is disposed within the first operating structure, with a first end coupled to the annular structure of the second connecting portion of the fixing device, a middle portion being adapted to fit the sleeve portion, and a second end extending from the sleeve portion and provided with the second gripping structure;

[0010] The operation structure one and the operation structure two rotate relatively, and the relative rotation of the control connection part one and the connection part two enables the clamping and fixing hook to clamp and fix the rib.

[0011] Further, at least one outwardly directed notch is arranged at the corresponding part of the outer edge of the ring structure where no locking tooth is arranged, the notch is composed of two vertical planes, and all notches and the outer edge of the ring structure form a non-circular operation matching structure one, and a hole slot is arranged at the first end of the operation structure one and matched with the operation matching structure one.

[0012] A non-circular slot is arranged in the cylindrical protruding structure, which is defined as an operation matching structure two, and a penetrating structure is arranged at the first end of the operation structure two and matched with the operation matching structure two.

[0013] In use, the operation structure one is sleeved to the outer side of the ring structure and matched with the operation matching structure one, the penetrating structure of the operation structure two is arranged in the non-circular slot, one of the operation structure one and the operation structure two is controlled to be stationary, and the other is rotated in the accurate rotation direction, and when the relative rotation cannot occur any more, the rotation is stopped, and the operation structure one and the operation structure two are withdrawn.

[0014] Further, an enlarged holding structure one is arranged at the second end of the operation structure one and matched with the longitudinal axis of the operation structure one, and an enlarged holding structure two is arranged at the second end of the operation structure two and matched with the longitudinal axis of the operation structure one.

[0015] Further, the first end of the holding structure one is a transition part, the second end is a cylindrical part one, the length of the cylindrical part one is less than 1 cm, the holding structure two includes a transition part at the first end and a cylindrical part two at the second end, and the length of the cylindrical part two is greater than 7 cm; the above arrangement can facilitate one hand to hold the holding structure one and the other hand to hold the holding structure two, and facilitate the force when the two hands rotate relatively.

[0016] Further, a longitudinal recess or protrusion is arranged at the outer side of the cylindrical part two, so as to increase the friction force in operation.

[0017] Further, in order to improve the matching and combination of the operation structure one and the ring structure, two short insertion rods are arranged at the first end of the operation structure one, and in use, the short insertion rods are inserted into the two sides of the ring structure and contacted with the connection part; in this way, the matching effect and the position maintaining state can be improved.

[0018] Further, because the whole operation is minimally invasive surgery, many operations are preferably performed outside the body, because once the operation is performed in the body, it will become more difficult, so if the operation structure is combined with the fixing device and fixed together, it will greatly reduce the difficulty of the operation and save the operation time. Specifically, the operation structure three is arranged for fixing the operation structure one and the operation structure two on the fixing device, and does not affect the mutual rotation structure of the operation structure one and the operation structure two, the operation structure one and the operation structure two are both cylindrical structures, the operation structure two is arranged in the operation structure one, and the operation structure three is fixed and combined with the cylindrical convex structure at the first end, and the limiting structure one for controlling the position of the operation structure one and the operation structure two is arranged at the second end of the operation structure two, and the limiting structure two for controlling the position of the operation structure two and the operation structure three is arranged at the second end of the operation structure three.

When in use, the operation structure one is first matched with the operation matching structure one, then the operation structure two is inserted into the operation structure one, the first end of the operation structure is inserted into the non-circular groove, then the threaded rod of the operation structure three is rotated and inserted into the threaded hole, and because of the accurate arrangement of the limiting ring and the limiting cap, the operation structure one to three can be prevented from being separated from the fixing device, and the rotation adjustment of the rotating locking part can be realized by the relative rotation of the operation structure one and the operation structure.

[0020] Further, the outer diameter of the limiting ring is greater than the inner diameter of the sleeve part of the operation structure one, and the outer diameter of the limiting cap is greater than the inner diameter of the operation structure two, so that effective limiting can be realized through the size arrangement.

[0021] Further, the second end of the operation structure two is further provided with a non-circular cap, the non-circular cap is provided with a channel for the operation structure three to extend into, the holding structure two is provided with a non-circular hole for matching with the non-circular cap, and the holding structure two is further provided with a limiting hole for accommodating the limiting cap; the non-circular cap is combined with the holding structure two, and the limiting cap is arranged in the holding structure.

[0022] Further, the non-circular cap is a regular hexagonal cap, and the corresponding non-circular hole is a regular hexagonal hole.

Specific implementation

[0043] Example 1, a rib fracture fixing instrument under endoscopic surgery rotation clamping rib

[0044] Reference Figure 2 , Figures 9-12The specific technical scheme of the fixing device is as follows: a rib fracture fixing device for turning and clamping under endoscopy, comprising four clamping fixing hooks 11, two cross-arranged connecting parts, and two connecting parts, namely connecting part one 21 and connecting part two 22; one clamping fixing hook 11 is arranged at the end of each connecting part, and the cross-arranged two connecting parts form two pairs of hook groups 1 for clamping and fixing ribs, with the two clamping fixing hooks 11 of each hook group 1 being arranged at the ends of the connecting part one 21 and the connecting part two 22; the device further comprises a turning and locking part arranged at the cross position between the two connecting parts, which can realize the turning adjustment and angle locking of the two connecting parts; the turning and locking part comprises a cylindrical protruding structure 31 arranged in the connecting part one 21 and integrally connected with the connecting part one 21, a circular ring structure 32 with a cylindrical hole groove arranged in the connecting part two 22 and integrally connected with the connecting part two 22, the cylindrical protruding structure 31 extending into the cylindrical hole groove to realize the cross combination of the connecting part one 21 and the connecting part two 22, a locking protrusion 33, and a plurality of circumferentially arranged locking teeth 34; the locking protrusion 33 is arranged on the outer side wall of the cylindrical protruding structure 31 or the inner side wall of the cylindrical hole groove, and the corresponding locking teeth 34 are arranged on the inner side wall of the cylindrical hole groove or the outer side wall of the cylindrical protruding structure 31; the locking protrusion 33 and the locking teeth 34 cooperate to allow the cylindrical protruding structure 31 to rotate in only one direction in the cylindrical hole groove and not to be reversed, so that the connecting part one 21 and the connecting part two 22 rotate in only one direction with the turning and locking part, and the rotation in only one direction causes the two clamping fixing hooks 11 of each hook group 1 to relatively approach, and the locking protrusion 33 enters the position between the corresponding two locking teeth 34 to lock the turning action of the connecting part one 21 and the connecting part two 22.

[0045] The above fixing device realizes the cross combination of the connecting part one 21 and the connecting part two 22 by extending the cylindrical protruding structure 31 into the cylindrical hole groove, rotates the circular ring structure 32 with a cylindrical hole groove around the cylindrical protruding structure 31 to realize the rotation of the connecting part one 21 and the connecting part two 22, and realizes the relative approaching movement of the two clamping fixing hooks 11 of each hook group 1, until the two clamping fixing hooks 11 of each hook group 1 are tightly attached to the two sides of the fractured rib, one hook group 1 is fixed on one side of the fractured rib, and the other hook group 1 is fixed on the other side of the fractured rib; after being tightly attached, the locking protrusion 33 enters the position between the corresponding two locking teeth 34, the connecting part one 21 and the connecting part two 22 no longer rotate in the reverse direction, and the two hook groups 1 naturally and stably fix the rib, realizing the rotation and position locking and achieving the purpose of rib fixation.

[0046] The specific fixed device is arranged as follows: the rotating locking portion is arranged at the middle of the connecting portion one 21 and the connecting portion two 22, and the two clamping fixed hooks 11 on each connecting portion are symmetrically arranged around the rotating locking portion; the two groups of fixed hook groups 1 have two states, one is an entering state, and the other is a clamping and fixing state. In the entering state, the distance between the two clamping fixed hooks 11 of each group of fixed hook groups 1 is greater than the width of the rib. In the clamping and fixing state, the distance between the two clamping fixed hooks 11 on the same side of the two groups of fixed hook groups 1 is L, and L is less than 2 cm. In this way, the clamping space formed by the four fixed hooks is basically consistent with the shape of the outer side of the rib in a short range, and the influence of the curved rib on the fixation of the rib is avoided. In addition, the small size can also meet the needs of minimally invasive surgery. More preferably, the connecting portion one 21 and the connecting portion two 22 are straight rods or straight plates.

[0047] Alternatively, the connecting portion one 21 and the connecting portion two 22 are arranged in a corresponding curved structure according to the curvature of the rib. This arrangement can ensure that the curvature is set as needed, but the structure of this arrangement is prepared by 3D printing according to the patient's condition to ensure effective matching and fixing effect.

[0048] More preferably, the shape of the hook bending position of each clamping fixed hook 11 is basically consistent with the edge curvature of the rib, and the fixed space formed by the two connecting portions and the two groups of fixed hook groups 1 is basically consistent with the shape of the rib. This way can ensure the fit of each part during fixation and avoid shaking during fixation.

[0049] More preferably, the connecting portion and the clamping fixed hook 11 are plate-shaped structures. This structure can ensure better clamping and fixing effect.

[0050] In use, the distance between the two clamping fixed hooks 11 on the same side of the two groups of fixed hook groups 1 in the entering state is small, and the distance between the two clamping fixed hooks 11 in the same group is large, which can ensure that the entire device enters the surgical position through a small incision and can be placed in a minimally invasive incision. In the entering state, the distance between the two clamping fixed hooks 11 of the same group of fixed hook groups 1 is greater than the width of the rib, which can ensure that the device falls into the fractured rib, the connecting portion is above the rib, and the lower hook edge of the clamping fixed hook 11 is above the rib. After entering, the device is adjusted from the entering state to the fixed state by adjusting the rotating locking portion. In the fixed state, the distance between the fixed hooks is increased, but the distance between the two clamping fixed hooks 11 of the same group of fixed hook groups 1 is equal to the width of the rib, so that the two clamping fixed hooks 11 of the same group of fixed hook groups 1 are tightly attached to the rib, and the two groups of fixed hook groups 1 are arranged on both sides of the rib fracture surface. This operation is also completed under the observation of the thoracoscope, which can further ensure that the incision of the entire operation is small and the patient recovers quickly.

[0051] In one embodiment, referring to Figure 13 The setting mode of the locking protrusion 33 and the locking teeth 34 can be that the locking protrusion 33 contains a guiding rotation inclined surface 331 and a reverse rotation preventing inclined surface 332, and a guiding rotation inclined surface 341 corresponding to the guiding rotation inclined surface and a reverse rotation preventing inclined surface 342 corresponding to the reverse rotation preventing inclined surface are arranged on the single locking teeth 34; and a rectangular slot 343 allowing deformation and a receiving slot 344 accommodating the locking protrusion 33 are arranged between the two locking teeth 34, and the receiving slot 344 is surrounded by the reverse rotation preventing inclined surface two and the guiding rotation inclined surface 341 on the two locking teeth 34; the adjustment of the position is realized when the locking protrusion 33 enters another receiving slot 344 from one receiving slot 344, the adjustment is realized by the guiding rotation action of the guiding rotation inclined surface 331 and the guiding rotation inclined surface 341, the locking of the adjusted position is ensured by the cooperation of the reverse rotation preventing inclined surface two in the receiving slot 344 and the reverse rotation preventing inclined surface one of the locking protrusion 33, and the self-locking technical effect is achieved, so that the difficulty of adjustment and operation can be reduced, and the effective fixation of the clamping and fixing hook 11 to the rib can be ensured without repetition.

[0052] Alternatively, the locking protrusion 33 is an inclined elastic sheet arranged on the cylindrical protruding structure 31 or the ring structure 32 with a cylindrical hole slot, and one of the locking teeth 34 is provided with a guiding surface and a reverse rotation preventing surface; the receiving slot 344 is arranged between the two locking teeth 34, the inclined elastic sheet is moved for adjustment on the guiding surface, and the inclined elastic sheet is blocked by the reverse rotation preventing surface when it reaches the receiving slot 344 between the two locking teeth 34 (not shown in the figure).

[0053] More preferably, referring to Figures 11-12 The through arc-shaped slot 35 accommodating the ring structure 32 is arranged on the connecting part one 21, and the ring structure 32 rotates in the arc-shaped slot 35, and the rotation action can be well stabilized by arranging the arc-shaped slot 35; more preferably, the anti-disengagement protruding plate 36 is arranged at the bottom of the ring structure 32, and the anti-disengagement slot 37 accommodating the anti-disengagement protruding plate 36 is arranged on the arc-shaped slot 35. The anti-disengagement protruding plate is centrally symmetrically arranged with two; the anti-disengagement slot 37 is arranged in the arc-shaped slot 35 on the two sides; the structure stability can be ensured by the cooperation of the rotation locking part through such arrangement.

[0054] More preferably, the anti-disengagement protruding plate 36 is an arc-shaped plate, the arc of the arc-shaped plate is A°; the arc of the part where the connecting part one 21 connects with the arc-shaped groove 35 is B°, and the arc of the part where the connecting part two 22 connects with the circular ring structure 32 is C°; the arc-shaped plate contacts the connecting part two 22; A≤180-B-C; wherein preferably A=B=C is 60°; when combined, the connecting part one 21 and the connecting part two 22 are combined in the area where the arc-shaped plate is not arranged, in the initial combined position, the locking protrusion 33 is inserted into the first arc-shaped groove 35 formed by the locking teeth 34, then after rotating an angle of one locking tooth 34, the anti-disengagement protruding plate 36 enters the anti-disengagement groove 37, realizing the anti-disengagement combination of the connecting part one 21 and the connecting part two 22, and constructing the fixer in the entering state. The fixer in the entering state constructed in this way is in an elongated state, which minimizes the surgical incision required in this state, and the fixer in this state is an effective combined position, which can not only combine the locking protrusion 33 and the locking teeth 34, but also combine the anti-disengagement protruding plate and the anti-disengagement groove 37, achieving the effect of not being able to rotate back and not being able to separate up and down, which is a very stable and effective entering state. It is achieved to effectively construct the combined state structure from the outside of the body, avoiding the difficulty of combination after entering the rib.

[0055] More preferably, two locking protrusions 33 are arranged, and two sets of locking teeth 34 are arranged correspondingly; the circumferential array angle of the locking teeth 34 is not less than the arc of the arc-shaped plate; the purpose of this arrangement is to ensure that the rotation is completed within a suitable rotation range.

[0056] More preferably, anti-slip protrusions are arranged on the inner sides of the connecting parts and the clamping hooks, and the anti-slip protrusions are arranged in the shape of a pyramid-shaped sharp cone structure. This arrangement can make the sharp end of the anti-slip protrusion inserted into the rib, improve the gripping force, and further ensure the stability of the fixed structure.

[0057] Example 2: A self-locking rib fracture fixer auxiliary operating instrument

[0058] Because the fixer in the prior art is small as a whole and is completed under minimally invasive conditions, the rotation of the connecting part one 21 and the connecting part two 22 cannot be completed by fingers, and a special operating instrument is needed to complete the rotation, so two operating structures are needed to cooperate to complete the combination of the connecting part one 21 and the connecting part two 22, and after the combination, the relative rotation of the connecting part one 21 and the connecting part two 22 is controlled to complete the operation of the fixer, so that the fixer changes from the entering state to the fixed state.

[0059] Reference Figures 1-8The operating device comprises: an operating structure 51, which is combined with the ring structure 32 of the connecting part 21 on the fixing device at the first end, has a sleeve part in the middle for leading the operating structure 51 out of the body, and has a holding structure 511 at the second end for holding the operating structure;

[0060] An operating structure 52, which is arranged inside the operating structure 51, is combined with the ring structure 32 of the connecting part 22 on the fixing device at the first end, has a structure adapted to the sleeve part in the middle, and has a holding structure 522 arranged from the sleeve part at the second end;

When in use, the operating structure one 51 is sleeved on the outer side of the circular ring structure 32 and clamped with the operating adaptation structure one, the extension structure of the operating structure two 52 is arranged in the non-circular slot 42, the operating structure one 51 or the operating structure two 52 is controlled to be stationary, the other one is rotated in the accurate rotation direction, and when relative rotation can no longer occur, the rotation is stopped, and the operating structure one 51 and the operating structure two 52 are withdrawn. The second end of the operating structure one 51 is provided with an outwardly extending handle for easy operation or an enlarged gripping structure one 511 whose longitudinal axis is consistent with that of the operating structure one 51; the second end of the operating structure two 52 is provided with an enlarged gripping structure two 522 whose longitudinal axis is consistent with that of the operating structure one 51. More specifically, the first end of the gripping structure one 511 is a transition part, and the second end is a cylindrical part one with a length less than 1 cm, the gripping structure two 522 includes a transition part at the first end and a cylindrical part two at the second end with a length greater than 7 cm; the above arrangement can facilitate one hand holding the gripping structure one 511 and the other hand holding the gripping structure two 522, and facilitate force when the two hands rotate relative to each other. More specifically, the outer side of the cylindrical part two is provided with a longitudinal recess or protrusion to increase the friction during operation. In a more preferred embodiment, in order to improve the adaptation and combination of the operating structure one 51 and the circular ring structure 32, the first end of the operating structure one 51 further extends two short insertion rods 512, which are inserted into the two sides of the circular ring structure 32 and contact the connecting part in the use state; in this way, the adaptation effect and position maintenance state can be improved.

[0062] Because the whole operation is minimally invasive surgery, many operations are best done outside the body, because once inside the operation will become difficult, so if the operation structure and fixed equipment combination fixed together, together into, will greatly reduce the difficulty of surgery, save operation time. Reference Figures 3-7 The specific implementation is to set a threaded hole 43 in the non-circular groove 42 for fixing the operation structure one 51 and the operation structure two 52 on the fixed equipment without affecting the mutual rotation structure of the operation structure one 51 and the operation structure two 52. Specifically, an operation structure three 53 is correspondingly set, and a threaded rod 531 of the operation structure three 53 is set to be inserted into the threaded hole 43. The operation structure one 51 and the operation structure two 52 are both cylindrical structures, the operation structure two 52 is set in the operation structure one 51, the operation structure three 53 is set in the operation structure two 52, the threaded rod 531 of the operation structure three 53 is combined with the threaded hole 43 to combine the operation structure one 51 to three with the fixed equipment.

A limiting cap 532 is set at the second end of the operation structure three 53 for limiting the movement of the operation structure two 52 and the operation structure three 53 in the longitudinal axis direction after combination. When in use, the operation structure one 51 is first adapted with the operation adapting structure one, then the operation structure two 52 is inserted into the operation structure one 51, the insertion structure 521 at the first end of the operation structure is inserted into the non-circular groove 42, then the threaded rod 531 of the operation structure three 53 is rotated into the threaded hole 43. Because of the accurate setting of the limiting ring 523 and the limiting cap 532, the operation structure one 51 to three can be ensured not to be separated from the fixed equipment, and the rotation adjustment of the rotation locking part can be realized by the relative rotation of the operation structure one 51 and the operation structure. The more preferred embodiment is that a non-circular cap 524 is further set at the second end of the operation structure two 52, a channel is set on the non-circular cap 524 for the operation structure three 53 to extend into, a non-circular hole 5221 is set on the holding structure two 522 for adapting with the non-circular cap 524, and a limiting hole 5222 is further set in the holding structure two 522 for accommodating the limiting cap 532. The non-circular cap 524 is combined with the holding structure two 522, and the limiting cap 532 is set in the holding structure. This setting can shorten the distance of the operation structure three 53, avoid affecting the strength of the operation structure three 53 because of too large distance, and achieve the control of the operation structure two 52 by rotating the holding structure two 522 through the multi-section combination adaptation.
