[0037] Specific technical solutions are as follows: Figures 8-10The utility model provides an operating instrument for facilitating the implantation of a rib fracture fixator under a laparoscope, comprising two clamping rotating structures, namely clamping rotating structure one 21 and clamping rotating structure two 22; each clamping rotating structure is provided with one clamping fixing hook 11 at both ends; the two clamping rotating structures are arranged in a cross manner, so that the four clamping fixing hooks 11 form two pairs of hooks that face each other to form a fixing hook group 1 for clamping and fixing ribs; one clamping fixing hook 11 of each fixing hook group 1 is at the end of clamping rotating structure one 21, and the other clamping fixing hook 11 is at the end of clamping rotating structure two 22; a rotating adjusting structure is arranged at the cross position between the two clamping rotating structures; the rotating adjusting structure comprises a cylindrical protruding structure 31 arranged in the middle of clamping rotating structure one 21 and integrally connected with clamping rotating structure one 21; a circular ring structure 32 provided with a cylindrical hole slot 321 is arranged in the middle of clamping rotating structure two 22 and integrally connected with clamping rotating structure two 22; the cylindrical protruding structure 31 extends into the cylindrical hole slot 321 to realize the cross combination of clamping rotating structure one 21 and clamping rotating structure two 22 and realize the position adjustment of clamping rotating structure one 21 and clamping rotating structure two 22 through the relative rotation of the circular ring structure 32 and the cylindrical protruding structure 31; a locking structure is used to lock the position relationship between the cylindrical protruding structure 31 and the circular ring structure 32; the locking structure comprises a locking threaded structure 33 arranged on the outside of the cylindrical protruding structure 31; a locking nut 34 is adapted to the locking threaded structure 33; the locking nut 34 rotates along the locking threaded structure 33 and moves downward; when the locking nut 34 moves downward, it pushes the circular ring structure 32 to move closer to clamping rotating structure one 21; finally, clamping rotating structure one 21 and clamping rotating structure two 22 are in close contact, and the position relationship of clamping rotating structure one 21 and clamping rotating structure two 22 is locked.

[0038] More preferably, a locking circular ring 322 is arranged in the cylindrical hole slot 321, and the locking circular ring 322 is integrally connected with the circular ring structure 32, and the locking threaded structure 33 extends from the locking circular ring 322; the locking nut 34 is arranged in the cylindrical hole slot 321, and the cross section of the locking nut 34 is a regular polygon, and the diameter of the circumscribed circle of the locking nut 34 is greater than the inner diameter of the circular ring structure 32; through this arrangement, the locking structure can be restricted inside the circular ring structure 32, without increasing the volume of the overall structure.

[0039] More preferably, the height of the locking nut 34 is equal to the depth of the cylindrical hole slot 321; this arrangement can avoid the adhesion and pain caused by the irritation of tissues due to the excessive height of the locking nut 34.

[0040] More preferably, the diameter of the circumscribed circle of the locking nut 34 is smaller than the diameter of the cylindrical hole slot 321; in this way, the operating instrument can be inserted between the locking nut 34 and the cylindrical hole slot 321 to adjust the rotation of the locking nut 34.

[0041] Or, the locking ring 322 is arranged in the cylindrical hole 321, and the locking ring 322 is integrally connected with the ring structure 32, the outer side of the locking nut 34 is circular in cross section, the outer diameter of the locking nut 34 is equal to the diameter of the cylindrical hole 321, and the operating gap is arranged on the outer side wall of the locking nut 34. The rotation of the locking nut 34 is realized by the operation structure clamped outside the operating gap, and the position relationship between the clamping rotating structure one 21 and the clamping rotating structure two 22 is realized by the downward movement of the locking ring 322 driven by the locking nut 34.

[0042] Or, the locking nut 34 is provided with a nut above, and the nut is provided with a through hole not less than the cylindrical protruding structure 31 in the middle; the outer diameter of the nut is greater than the diameter of the cylindrical hole 321, and the nut is provided with an operating gap on the outer edge. The rotation of the locking nut 34 is realized by the operation structure clamped outside the operating gap, and the position relationship between the clamping rotating structure one 21 and the clamping rotating structure two 22 is realized by the downward movement of the ring structure 32 driven by the nut.

[0043] By extending the cylindrical protruding structure 31 into the cylindrical hole 321, the clamping rotating structure one 21 and the clamping rotating structure two 22 are combined in cross, the locking nut 34 is sleeved outside the locking thread structure 33, the relative rotation between the ring structure 32 with the cylindrical hole 321 and the cylindrical protruding structure 31 is controlled, the rotation of the clamping rotating structure one 21 and the clamping rotating structure two 22 is realized, and the relative close movement of the two clamping fixing hooks 11 in the same group of fixing hooks group 1 is realized, until the two clamping fixing hooks 11 in each group are closely attached to the two sides of the fractured rib, one group of fixing hooks group 1 is fixed on one side of the rib fracture surface, and the other group of fixing hooks group 1 is fixed on the other side of the rib fracture surface. When the effective close is realized, the rotation of the locking nut 34 is controlled, so that the clamping rotating structure one 21 and the clamping rotating structure two 22 are in longitudinal close contact, until the position relationship between the clamping rotating structure one 21 and the clamping rotating structure two 22 is locked, and the two groups of fixing hooks group 1 stably fix the rib.

[0044] More preferably, the rotation locking portion is arranged at the middle of the first clamping rotation structure 21 and the second clamping rotation structure 22, and the rotation locking portion is the center, and the two clamping hooks 11 on each clamping rotation structure are symmetrically arranged at the center; the two groups of clamping hooks 1 have two states, one is an entering state, and the other is a clamping state. In the entering state, the distance between the two clamping hooks 11 of each group of clamping hooks 1 is greater than the width of the rib, and in the clamping state, the distance between the two clamping hooks 11 on the same side of the two groups of clamping hooks 1 is L, and L is less than 2 cm. In this way, the clamping space formed by the four clamping 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 first clamping rotation structure 21 and the second clamping rotation structure 22 are straight rod or straight plate structures.

[0045] Alternatively, the first clamping rotation structure 21 and the second clamping rotation structure 22 are arranged as corresponding curved structures according to the curvature of the rib. This arrangement can ensure that the curvature is set as needed, but the structure of this way is prepared by 3D printing according to the patient's condition; to ensure effective anastomosis and fixation effect.

[0046] More preferably, the shape of the hook bending position of each clamping hook 11 is basically consistent with the edge curvature of the rib, and the fixed space formed by the two clamping rotation structures and the two groups of clamping hooks 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.

[0047] More preferably, the clamping rotation structure and the clamping hook 11 are plate-shaped structures; this structure can ensure better clamping and fixing effect.

[0048] When in use, the locking nut 34 is combined with the locking screw structure, so that the clamping rotating structure one 21 and the clamping rotating structure two 22 are in contact but can still rotate relatively; after the clamping and fixing position is found, the locking nut 34 is continued to be rotated to lock the position relationship between the clamping rotating structure one 21 and the clamping rotating structure two 22. The distance between the two clamping fixing hooks 11 on the same side of the two groups of fixing hook groups 1 in the entering state is small, and the distance between the two clamping fixing hooks 11 in the same group is large, which can ensure that the whole instrument enters the surgical position through a small incision and can be placed in a minimally invasive manner. In this state, the distance between the two clamping fixing hooks 11 in the same group of fixing hook groups 1 is greater than the width of the rib, and this arrangement can ensure that the instrument falls into the fractured rib, the clamping rotating structure is above the rib, and the lower hook edge of the clamping fixing hook 11 is above the rib. After entering, the instrument is adjusted from the entering state to the fixing state by rotating the locking nut 34. In the fixing state, the distance between the control fixing hooks is increased, but the distance between the two clamping fixing hooks 11 in the same group of fixing hook groups 1 is equal to the width of the rib, so that the two clamping fixing hooks 11 in the same group of fixing hook groups 1 are tightly attached to the rib to clamp and fix the rib. The two groups of fixing hooks 1 are respectively arranged on the two sides of the rib fracture surface, and the operation is completed under the observation of the thoracoscope. This can further ensure that the incision of the whole operation is small and the patient recovers quickly.

[0049] More preferably, an arc-shaped groove 35 is arranged on the clamping rotating structure one 21 to accommodate the through circular ring structure 32, and the circular ring structure 32 rotates in the arc-shaped groove 35. The arrangement of the arc-shaped groove 35 can well stabilize the rotating action.

[0050] More preferably, the whole fixing instrument is made of absorbable material. This arrangement can avoid secondary injury to the patient caused by the removal of the fixing instrument and can also avoid tissue adhesion caused by long-term placement in the body.

[0051] More preferably, anti-skid protrusions 6 are arranged on the inner side of the clamping rotating structure, and the anti-skid protrusions 6 are in the shape of a sharp cone similar to a pyramid. The whole clamping rotating structure is provided with anti-skid protrusions. This arrangement can further improve the gripping force by piercing the rib with the sharp end, ensure the stability of the fixed position after fixation, and avoid slipping.

[0052] Because the whole fixing instrument is small and is completed under minimally invasive conditions, the rotation of the clamping rotating structure one 21 and the clamping rotating structure two 22 cannot be completed by fingers and needs to be completed with the help of a special operation structure. Therefore, corresponding structures need to be arranged on the clamping rotating structure one 21 and the clamping rotating structure two 22 to adapt to the operation structure, so as to ensure the relative rotation of the clamping rotating structure one 21 and the clamping rotating structure two 22 and the locking control after the appropriate position is found outside the body.

[0053] Specifically, referring toFigures 1-2 , Figure 8 ; the outer edge of the circular ring structure 32 is provided with a notch, or an array of insertion holes 41, for combination with the operation structure one 51, to control the fixation or rotation of the circular ring structure 32 through the operation structure one 51; the operation structure one 51 is correspondingly provided with a hole to fit in the notch or an insertion rod 512 to insert into the insertion hole 41.

[0054] The non-circular fitting structure is provided on the outer edge or top of the locking nut 34, and the operation structure two 52 is correspondingly provided, and the operation structure two 52 is provided with a structure that fits the non-circular fitting structure.

[0055] The threaded hole 42 is provided in the cylindrical protruding structure 31, and the threaded hole 42 is provided with a stop structure, and the operation structure three 53 is correspondingly provided, and the operation structure three 53 is provided with a threaded section 532, which stops rotating after rotating to the stop structure position, and when rotating again, it can drive the rotation of the clamping rotating structure one 21. Or the threaded hole 42 does not penetrate the cylindrical protruding structure 31, and when the threaded section 532 of the operation structure rotates to the bottom of the threaded hole 42, it naturally stops rotating, and when rotating again, it can drive the rotation of the clamping rotating structure one 21.

[0056] The operation method of minimally invasive surgery is: first, make two small openings at the position of the fractured rib, one small opening to send the thoracoscope to the operation position, and one small opening to send the combined fixation instrument and the operation structure one 51 to three to the operation position, or after the fixation instrument is sent to the operation position, the operation structure one 51 to three is sent to the operation position through the same channel, and combined with the fixation instrument in the body; the four clamping fixation hooks 11 of the fixation instrument are arranged at the positions on both sides of the rib, then the operation structure one 51 is controlled not to move, the operation structure three 53 is rotated to drive the clamping rotating structure to rotate, so that the clamping fixation hooks 11 are tightly attached to the rib, then the position of the operation handle 511 of the operation structure one 51 and the rotating handle three 531 of the operation structure three 53 is controlled not to change, then the rotating handle two 521 of the operation structure two 52 is controlled to rotate the locking nut 34, so that the two clamping rotating structures are pushed to move closer to each other in the longitudinal axis direction without rotating, and finally the clamping rotating structures tightly locked to the rib are tightly locked.
