[0026] like Figures 1 to 5 As shown, this embodiment provides a rotating shaft ring connection structure for suspending surgical instruments, including a mounting shaft rod 1, on which a movable collar 2 for suspending and connecting the surgical instrument is sleeved, and a fastening assembly is provided between the movable collar and the mounting shaft rod to facilitate the positioning of the movable collar after sliding and rotating adjustment on the mounting shaft rod.

[0027] The movable collar can slide back and forth along the axial direction on the mounting shaft to adjust the position, and can also rotate 360° around the axial direction to adjust the position. After the adjustment is completed, it is positioned by the fastening assembly, which is more flexible and convenient to use, has high adjustment efficiency, and stable operation.

[0028] In the embodiment of the present invention, the fastening assembly adopts a set screw 3, which is threadedly connected to the movable collar and presses against the mounting shaft.

[0029] The set screw is used to tighten and radially press the mounting shaft, and the position of the movable collar on the mounting shaft is fixed at this time; when the set screw is loosened, the position of the movable collar can be adjusted again.

[0030] In the embodiment of the present invention, the set screw is a butterfly screw.

[0031] The butterfly screw enables the operator to directly rotate the set screw by hand, which is easy to operate.

[0032] In the embodiment of the present invention, a suspending member is connected to the side of the movable collar, and the surgical instrument is connected to the bottom of the suspending member.

[0033] Wherein, the movable collar is first connected to the suspension member, and the suspension member is then connected to the surgical instrument.

[0034] In the embodiment of the present invention, the suspension member is a hook plate 4, which is provided with a mounting groove 5 extending along its length direction, and a locking screw 6 is provided on the mounting groove. The threaded section of the locking screw passes through the mounting groove and is screwed and locked on the side of the movable ring.

[0035] After the locking screw is loosened, the height of the hook piece can be adjusted up and down along the installation groove, and the angle of the hook piece can be adjusted by swinging; after the locking screw is locked, the height and angle of the hook piece are fixed, so that the height and angle of the surgical instrument can be adjusted.

[0036] In the embodiment of the present invention, the top end of the hook piece has an upper bending portion, and the upper bending portion forms a lifting handle 7.

[0037] Wherein, the upper bending portion is perpendicular to the hook piece, and the operator can pinch the lifting handle with his hand to facilitate the up and down pulling operation when adjusting the height of the hook piece.

[0038] In the embodiment of the present invention, the locking screw is a butterfly screw.

[0039] Among them, the butterfly screw can be convenient for the operator to directly rotate the locking screw by hand, which is easy to operate.

[0040] In the embodiment of the present invention, the installation shaft rod is a round rod, and the movable sleeve ring is a circular ring.

[0041] In the embodiment of the present invention, a section of inferior arc is cut off on both opposite outer circumferential sides of the installation shaft rod, so that the installation shaft rod as a whole forms a shaft rod structure with a circumferential shape of two opposite flat surfaces 8 and two opposite arc surfaces 9.

[0042] In an embodiment of the present invention, the installation shaft and the movable collar are coaxially arranged.

[0043] In the embodiment of the present invention, the mounting shaft is mounted on the shaft connecting ring 10 .

[0044] In the embodiment of the present invention, a shaft rod insertion hole 11 is provided on the shaft rod connecting ring, and the shape of the shaft rod insertion hole is adapted to the shape of the mounting shaft rod.

[0045] In the embodiment of the present invention, a set screw in the form of a butterfly screw is threadedly connected to the shaft rod insertion hole for rotating and tightening the shaft rod.

[0046] There are two shaft rod insertion holes, and the horizontal axes of the two shaft rod insertion holes are perpendicular to each other, so that the two inserted installation shaft rods are perpendicular to each other, and one of the installation shaft rods is finally connected to the main beam 12 of the surgical suspension system.

[0047] Among them, since the shape of the shaft rod insertion hole is adapted to the shape of the installation shaft rod, the installation shaft rod with double relative planes and double relative arc surfaces cannot deflect around its own axis in the shaft rod insertion hole, and the structure is more stable, thereby improving the quality and safety of the operation.

[0048] In the embodiment of the present invention, the surgical instrument is universally connected to the bottom of the retractor piece.

[0049] In the embodiment of the present invention, a connecting rod 13 is fixedly connected to the non-executing end of the surgical instrument, and a ball head 14 is fixedly disposed at the end of the connecting rod.

[0050] In an embodiment of the present invention, the outer diameter of the ball head is greater than the outer diameter of the connecting rod.

[0051] In the embodiment of the present invention, the bottom end of the hook piece has a lower bending portion 15 , and an embedded through hole 16 is opened on the lower bending portion. The outer peripheral side of the embedded through hole passes through the embedded notch 17 to the outside.

[0052] In the embodiment of the present invention, the inner diameter of the embedded through hole is larger than the width of the embedded notch, but smaller than the outer diameter of the ball head; the width of the embedded notch is equal to the outer diameter of the connecting rod.

[0053] In the embodiment of the present invention, the ball head is embedded in the embedding through hole.

[0054] When installing the ball head, the connecting rod first passes through the embedded notch and enters the embedded through hole, and then the ball head is placed on the embedded through hole. Since the outer diameter of the ball head is larger than the inner diameter of the embedded through hole, the ball head will not fall down. The rotation of the ball head in the embedded through hole can achieve a universal connection, thereby expanding the surgical operation space.

[0055] In an embodiment of the present invention, the surgical instrument includes a grasping thorn.

[0056] In the embodiment of the present invention, the grab barb is composed of a left and a right grab bar in a "J" shape. The top ends of the left grab bar 18 and the right grab bar 19 are hinged to each other, and the bottom ends form an execution end, i.e., a grab opening.

[0057] In an embodiment of the present invention, the connecting rod is fixed to the top of the hinge point of the left grab bar or the right grab bar.

[0058] In the embodiment of the present invention, the non-end inner sides of the left grabbing rod and the right grabbing rod are fixed with front and rear arranged clamping rods 20, and the front and rear adjacent clamping surfaces of the two clamping rods are meshed through serrations 21, and the biting direction of the serrations is left and right, which can ensure the clamping of the left and right grabbing rods, ensure the stability of the grabbing barbs during use, and prevent the tissue part clamped in the grabbing mouth from loosening and falling off easily.

[0059] In the embodiment of the present invention, the outer sides of the non-end portions of the left grab bar and the right grab bar are both fixedly provided with outwardly protruding handles 22 at positions corresponding to the clamping rods.

[0060] In the embodiment of the present invention, the overall outer contour of the thorn is an arc-shaped structure that is narrow at the top and wide at the bottom, and is similar to a "water drop" shape as a whole. When in use, it is more ergonomic, easy to hold and operate, and at the same time increases the aesthetics and comfort of the device.

[0061] In the embodiment of the present invention, the clamping rod and the protruding handle are arranged in the upper middle part of the "water drop" shaped grab bar, and the overall width of this part of the grab bar is relatively narrow, which can be convenient for the operator to grasp with one hand.

[0062] When the grab bar is in use, the operator pinches the left grab bar near the clamping bar with his left hand, pinches the right grab bar near the clamping bar with his right hand, and then slightly forces the left and right grab bars to be pried back and forth. The left and right grab bars can be elastically deformed to a certain extent, and the saw teeth of the left and right grab bars are transformed from engagement to disengagement by moving back and forth. At the same time, the operator pries the grab bar to the left and right with both hands to open the grab bar. Next, the operator can rely on the convex handle to operate the grab bar from opening to closing with one hand.

[0063] When the grab bar is to be closed, the left and right grab bars only need to be tightly grasped with one hand, and the two clamping bars will move closer to each other left and right and abut against each other front and back until the clamps are engaged, and the grab opening is also clamped in place after the engagement is in place.

[0064] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
