DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0038] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0039] Example 1

[0040] Reference Figures 1 and 2 , which is the first embodiment of the present invention, provides a multi-axis fixing device for laparoscopic instruments on an operating table, including a fixing cylinder 100. The inner wall of the fixing cylinder 100 is provided with an observation hole 101. Through the observation hole 101, medical staff can observe the situation inside the fixing device, thereby making adjustments more accurate.

[0041] The connecting assembly 200 connects the fixed tube 100 and the incision protector Q and includes an adjusting screw 201, a lower clamp 202, an upper clamp 203, and a stopper 204. The adjusting screw 201 is threaded onto the outside of the fixed tube 100. The fixing assembly 300, used to secure and position the thoracoscope, includes a fixing frame 301, a direction member 302, and an adjusting member 303. A cavity is defined within the fixed tube 100. Multiple observation holes 101 are provided, with the connecting assembly 200 and fixing assembly 300 located at the bottom and top of the fixed tube 100, respectively.

[0042] In actual use, the multi-axis fixation device should be connected to the incision protector Q, which is generally I-shaped and directly covers the wound when used to prevent infection. The thoracoscope is then fixed by the multi-axis fixation device. The significance of the multi-axis fixation device here is to restrict the thoracoscope so that it cannot shake significantly in the radial direction. However, the thoracoscope itself can still achieve axial movement and rotation, as well as swing in all directions, thanks to the structure of the fixation device.

[0043] Example 2

[0044] Reference Figures 3 to 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: in order to ensure the stable connection between the fixed tube 100 and the incision protector Q, it is necessary to clamp from the upper and lower surfaces of one end of the incision protector Q, wherein the lower clamping piece 202 is used to clamp the lower surface of the outer end of the incision protector Q.

[0045] The lower clamp 202 includes a notch groove 202a, a rotating plate 202b, an L-shaped plate 202c, an arc-shaped baffle 202d and an arc-shaped groove 202e. The notch groove 202a is opened on the bottom end surface of the fixed cylinder 100, the rotating plate 202b and the L-shaped plate 202c are rotatably set on the inner wall of the notch groove 202a, the arc-shaped baffle 202d is fixedly set on the inner side of the notch groove 202a, and the arc-shaped groove 202e is opened on the side of the L-shaped plate 202c.

[0046] Among them, there are multiple notched grooves 202a and they are evenly distributed on the bottom side of the fixed cylinder 100. The rotating plate 202b is located on the side of the inner wall of the notched groove 202a away from the center of the fixed cylinder 100, and the L-shaped plate 202c is located on the inner side of the rotating plate 202b; the arc-shaped baffle 202d is used to limit the rotation of the L-shaped plate 202c, and the arc-shaped groove 202e has an arc edge at the edge to prevent the L-shaped plate 202c from being stuck by the arc-shaped baffle 202d when rotating.

[0047] The lower clamp 202 also includes an L-shaped groove 202f, an L-shaped slider 202g, a spring 202h and a silicone pad 202i. The L-shaped groove 202f is opened on the side of the L-shaped plate 202c, the L-shaped slider 202g is slidably set on the inner side of the L-shaped groove 202f, and the two ends of the spring 202h are respectively fixed on the side of the L-shaped slider 202g and the inner side of the L-shaped groove 202f. The silicone pad 202i is fixed on the end of the L-shaped slider 202g away from the rotating plate 202b, and the side wall of the rotating plate 202b cooperates with the sliding end of the L-shaped slider 202g.

[0048] The L-shaped groove 202f passes through the bottom part of the L-shaped plate 202c and the part opened on the side of the L-shaped plate 202c respectively, and the L-shaped slider 202g can just fit the shape of the L-shaped groove 202f and can slide in it; the spring 1 202h is used to reset the L-shaped slider 202g; the rotating shaft of the L-shaped plate 202c is connected to the inner wall of the notch groove 202a through the torsion spring, so it can be reset after rotation.

[0049] The function of the silicone pad 202i is to protect the patient's wound. Since the lower clamp 202 has the probability of contacting the patient's surgical incision, protective measures are required. First, the silicone pad 202i itself is made of soft material and can protect the patient's wound from secondary damage. Second, when the fixing device is not in use, the silicone pad 202i itself is located inside the L-shaped slide groove 202f, thereby playing a role in preventing dust and bacteria.

[0050] When not in use, the L-shaped slider 202g fits in the L-shaped groove 202f, the silicone pad 202i is located inside the L-shaped groove 202f, and under the action of the torsion spring, the L-shaped plate 202c rotates toward the outside of the fixed cylinder 100, and the side end of the L-shaped slider 202g abuts against the side of the rotating plate 202b.

[0051] The upper clamp 203 includes a fixed ring 203a, a folding rod 203b, a fixed plate 203c, and a limiting frame 203d. The fixed ring 203a is sleeved on the side of the fixed cylinder 100 and rotatably mounted on the top of the adjusting screw ring 201. The folding rod 203b is fixedly mounted on the top of the fixed ring 203a. The limiting frame 203d is fixedly mounted on the end of the folding rod 203b. The limiting frame 203d is fixedly mounted on the inner side of the fixed cylinder 100, and the folding rod 203b is slidably mounted on the inner wall of the limiting frame 203d. The upper clamp 203 and the lower clamp 202 are each provided with multiple groups, and the upper clamp 203 and the lower clamp 202 are arranged in a staggered manner.

[0052] Among them, the advantage of the staggered setting is that when the upper clamp 203 and the lower clamp 202 are close to each other, they will squeeze the upper and lower surfaces of the incision protector Q. Since the incision protector Q is made of silicone, it will be squeezed and deformed, and eventually the fixed plate 203c of the upper clamp 203 and the L-shaped plate 202c of the lower clamp 202 will be staggered and flush. This not only increases the clamping force, but also keeps the end face of the incision protector Q flush as a whole, preventing the patient from feeling any strange sensation in the incision.

[0053] The stopper 204 includes a square frame 204a and a tightening strap 204b. The square frame 204a is fixed to the bottom of the fixed tube 100, and the tightening strap 204b is sleeved on one side of the square frame 204a. There are two tightening straps 204b located on both sides of the fixed tube 100, and the ends of the tightening straps 204b are connected to buckles for connecting the two tightening straps 204b together.

[0054] During use: After the incision protector Q is placed on the patient's wound, the medical staff moves the fixing device close to the incision protector Q until the L-shaped plate 202c is lower than the end face of the incision protector Q. Then the medical staff holds the fixing tube 100 with one hand and turns the adjusting screw ring 201 with the other hand. The adjusting screw ring 201 moves axially along the fixing tube 100 under the action of the thread. During the movement, the bottom of the adjusting screw ring 201 squeezes the rotating plate 202b, and the rotating plate 202b squeezes the L-shaped slider 202g and the L-shaped plate 202c, so that the L-shaped plate 202c drives the L-shaped slider 202g to approach the fixed tube 100, and is finally blocked by the arc-shaped blocking rod 202d; at the same time, the fixing ring 203a drives the folding rod 203b and the fixing plate 203c to move downward, and under the staggered squeezing of the upper clamp 203 and the lower clamp 202, the fixing tube 100 and the incision protector Q are successfully connected; finally, the tightening belt 204b is wrapped around the patient's chest and then tightened, thereby completing the connection between the fixing device and the incision protector Q and the stability of the fixing device itself.

[0055] The remaining structures are the same as those of Example 1.

[0056] Example 3

[0057] Reference Figures 7 and 8, which is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the fixing frame 301 is the main means of restricting the thoracoscope, the hole in the center of the fixing frame 301 is larger than the hole of the incision protector Q, wherein the direction member 302 is used to realize the multi-axis rotation of the fixing frame 301, and the adjustment member 303 is used to realize the adaptive clamping of the fixing frame 301 to thoracoscopes of different specifications.

[0058] The direction member 302 includes a rotating ring 1 302a and a rotating ring 2 302b. The rotating ring 1 302a is rotatably set on the inner side of the fixed cylinder 100, and the rotating ring 2 302b is rotatably set on the inner side of the rotating ring 1 302a through a rotating shaft. The fixed frame 301 is rotatably set on the inner side of the rotating ring through a rotating shaft. The rotation center of the rotating ring 2 302b and the fixed frame 301 is perpendicular.

[0059] Adjustment member 303 includes a lifting slide 303a, a connecting ring 303b, a movable ring 303c, a rubber concave block 303d, a rubber bump 303e, and an extrusion ring 303f. Lifting slide 303a extends through and slides along the inside and outside of fixed frame 301. Connecting ring 303b is located outside fixed frame 301 and fixed to the end of lifting slide 303a. Moving ring 303c is rotatably mounted on top of connecting ring 303b. Extrusion ring 303f is located inside fixed frame 301 and fixed to the end of lifting slide 303a. Rubber bump 303e is fixed to the inside of movable ring 303c, while rubber concave block 303d is fixed to the outside of fixed frame 301. Rubber bump 303e and rubber bump 303d are tightly attached when connected.

[0060] There are several lifting slide bars 303a, which are evenly spaced on the upper surface of the fixed frame 301. There is only one extrusion ring 303f, which is connected to multiple lifting slide bars 303a. When the rubber protrusion 303e and the rubber concave block 303d are clamped together, the moving ring 303c and the fixed frame 301 are fixed by friction between them.

[0061] Adjustment member 303 also includes a movable slide 303g, a curved plate 303h, a stop plate 303i, and a second spring 303j. The movable slide 303g extends through and slides along the inner and outer sides of the center of the fixed frame 301. The curved plate 303h and the stop plate 303i are fixedly mounted at both ends of the movable slide 303g. The inner side of the extrusion ring 303f slides along the side of the curved plate 303h. The second spring 303j is fixedly mounted on the side of the curved plate 303h and the inner side of the fixed frame 301. The second spring 303j is used to return the movable slide 303g to its original position after movement.

[0062] During use: first insert the thoracoscope into the fixing frame 301, the thoracoscope passes through the incision protector Q and enters the human chest cavity, then the medical staff pushes the moving ring 303c, the moving ring 303c drives the connecting ring 303b to move downward, during the downward movement, the squeezing ring 303f squeezes the curved plate 303h, the curved plate 303h is squeezed by the force to squeeze the moving slide 303g, and the moving slide 303g drives the abutment plate 303i to approach the thoracoscope, and finally multiple abutment plates 303i limit the thoracoscope at the center of the fixing frame 301, and then the moving ring 303c can be rotated, and the moving ring 303c is fixed by the rubber convex plate and the rubber concave plate. Here, the abutment plate 303i only contacts the thoracoscope and plays a limiting role, but does not fix the chest cavity. In actual use, medical staff can use the direction member 302 to realize multi-axis rotation of the thoracoscope, and can also realize its axial movement.

[0063] Therefore, after using the fixing device, medical personnel can not only operate the thoracoscope flexibly, but also limit the position of thoracoscopes of different specifications by adjusting the movable ring 303c.

[0064] The remaining structures are the same as those of Example 2.

[0065] Example 4

[0066] Example 4 is a further improvement based on Example 2 and Example 3. In order to improve aseptic operation and reduce direct contact between the tightening belt 204b and the patient's body, when fixing the fixing device itself, the tightening belt 204b can also be wrapped around the operating bed and then tightened to complete the stabilization of the fixing device itself.
