DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] like Figures 1 to 5 As shown, this embodiment provides a surgical grasping structure, including an arc-shaped left grasping rod 18 and a right grasping rod 19, the top ends of the left grasping rod and the right grasping rod are hinged to each other, a grasping opening is formed between the bottom ends, and the overall outer contour of the grasping rod composed of the left and right grasping rods is a teardrop shape that is narrow at the top and wide at the bottom.

[0026] In the embodiment of the present invention, the gripping portion of the thorn is in the upper middle portion of the water drop shape.

[0027] The overall outer contour of the surgical thorn-grabbing structure is a water drop shape that is narrow at the top and wide at the bottom. When medical staff operate, firstly, the outer contour of the water drop shape is relatively smooth and the transition is gentle, which is comfortable to hold and not easy to hurt the hand. Secondly, when the hand grasps the outer contour of the water drop shape, the inner side of the palm of this case can fit with the outer contour of the thorn in a larger area than the prior art, which can achieve precise grasping and smooth control during manual operation, and is more conducive to precise force application.

[0028] In the embodiment of the present invention, there is an intermediate lock buckle between the left grab bar and the right grab bar.

[0029] In the embodiment of the present invention, the intermediate lock includes a clamping rod 20 fixed on the inner side of the left grab bar and the right grab bar and distributed front and back. The front and rear adjacent clamping surfaces of the two clamping rods are meshed through serrations 21, and the meshing direction between the serrations is left and right.

[0030] In the embodiment of the present invention, the outer sides of the left grab bar and the right grab bar are both fixedly provided with an outwardly protruding handle 22 at positions corresponding to the clamping rods.

[0031] In the embodiment of the present invention, the middle lock buckle is located in the upper middle part of the teardrop-shaped grab barb.

[0032] The teardrop-shaped grab barb is more ergonomic when used, especially since the gripping part and the middle lock buckle are arranged in the upper and middle part of the teardrop shape. The width of this part is just right, which is convenient for holding and operation, while increasing the aesthetics and comfort of the grab barb.

[0033] When the middle lock is used, the operator holds the part of the left grab bar near the clamping bar with his left hand, and holds the part of the right grab bar near the clamping bar with his right hand, and then slightly pushes the left and right grab bars forward and backward, so that 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 can be turned from meshing to disengaging by moving forward and backward. At the same time, the operator pushes the grab bar left and right with both hands, so that the grab bar can be opened to grab skin tissue. Then the operator can rely on the convex handle to operate the grab bar from opening to closing with one hand.

[0034] When the grab is to be closed, just hold the left and right grab bars tightly with one hand, and the two connecting bars will move closer to each other and abut against each other front and back until they are engaged. After the engagement is in place, the grab is also clamped in place. Under the constraint of the serrated engagement, the left and right grab bars are not easy to loosen left and right, and the skin tissue can be clamped.

[0035] In the embodiment of the present invention, a suspension rod is arranged above the grab bar formed by the left grab bar and the right grab bar, and the suspension rod and the grab bar are connected via a universal joint to facilitate the universal adjustment of the grab bar.

[0036] In an embodiment of the present invention, the universal joint includes a connecting rod 13 fixed at the top of the hinge point of the left grab bar or the right grab bar, a ball head 14 is fixed to the end of the connecting rod, and an embedded through hole 16 is provided at the bottom end of the suspension rod, and the ball head is embedded in the embedded through hole.

[0037] In the embodiment of the present invention, the bottom end of the suspension rod has a lower bending portion 15 , the embedded through hole is opened on the lower bending portion, and the outer peripheral side of the embedded through hole passes through the embedded notch 17 to the outside.

[0038] 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.

[0039] 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.

[0040] In an embodiment of the present invention, the suspension rod is a suspension rod, and the suspension rod is installed on a surgical suspension system.

[0041] In an embodiment of the present invention, the surgical suspension system includes a rotating shaft ring connection structure, which includes a mounting shaft rod 1, on which is provided a movable collar 2 for suspending and connecting a surgical thorn, 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] In the embodiment of the present invention, the set screw is a butterfly screw.

[0046] The butterfly screw enables the operator to directly rotate the set screw by hand, which is easy to operate.

[0047] In the embodiment of the present invention, the suspension rod is connected to the side of the movable ring, and the surgical thorn is connected to the bottom of the suspension rod.

[0048] Wherein, the movable collar is first connected to the suspension rod, and the suspension rod is universally connected to the surgical thorn.

[0049] In the embodiment of the present invention, the suspension rod 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.

[0050] 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 thorn can be adjusted.

[0051] 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.

[0052] 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.

[0053] In the embodiment of the present invention, the locking screw is a butterfly screw.

[0054] Among them, the butterfly screw can be convenient for the operator to directly rotate the locking screw by hand, which is easy to operate.

[0055] In the embodiment of the present invention, the installation shaft rod is a round rod, and the movable sleeve ring is a circular ring.

[0056] 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.

[0057] In an embodiment of the present invention, the installation shaft and the movable collar are coaxially arranged.

[0058] In the embodiment of the present invention, the mounting shaft is mounted on the shaft connecting ring 10 .

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms.
