Description

[0001] This application claims priority to the invention entitled "A Multi-Axis Fixation Device for Laparoscopic Instruments on an Operating Table" with application number "202410754229.8", application date "June 12, 2024". Technical Field

[0002] This invention relates to the field of medical device technology, and in particular to a multi-axis fixation device for laparoscopic instruments on an operating table. Background Technology

[0003] Thoracoscopic surgery involves inserting a lens and instruments through a small incision. Using endoscopic techniques and miniature instruments, it allows for the examination and manipulation of structures within the thoracic cavity under direct visualization. This surgical technique has revolutionized the traditional treatment of thoracic diseases and is considered one of the most significant advancements in thoracic surgery. Thoracoscopic surgery is primarily used to observe the internal condition of organs such as the lungs and heart, and it plays a crucial role in the diagnosis of various pleural and pulmonary diseases, such as infectious pneumonia and tuberculous pleurisy.

[0004] During thoracoscopic surgery, the surgeon holds the thoracoscope, and the fixation between the thoracoscope and the patient is usually achieved through an incision protector. However, the incision protector is generally made of silicone, which is easily deformed by the tube of the thoracoscope, causing the thoracoscope to shake during the operation and the lens to capture blurry images. Therefore, it is necessary to use auxiliary fixation for the thoracoscope. Summary of the Invention

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used 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 different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0039] Example 1

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

[0041] The connecting assembly 200, used to connect the fixing cylinder 100 and the incision protector Q, includes an adjusting screw ring 201, a lower clamp 202, an upper clamp 203, and a limiting member 204. The adjusting screw ring 201 is sleeved and threadedly connected to the outside of the fixing cylinder 100. The fixing assembly 300, used to fix and limit the thoracoscope, includes a fixing frame 301, a directional member 302, and an adjusting member 303. A cavity is formed on the inner side of the fixing cylinder 100. Multiple observation holes 101 are provided. The connecting assembly 200 and the fixing assembly 300 are located at the bottom and top ends of the fixing cylinder 100, respectively.

[0042] In practical use, the multi-axis fixation device should be connected to the incision protector Q. The incision protector Q is generally I-shaped and directly covers the wound to prevent infection. The thoracoscope is then fixed using the multi-axis fixation device. The significance of the multi-axis fixation device here is to restrict the thoracoscope, preventing it from swaying significantly radially, while still allowing axial movement, rotation, and lateral swinging thanks to the structure of the fixation device.

[0043] Example 2

[0044] Reference Figures 3-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that, in order to ensure the stable connection between the fixed cylinder 100 and the cut protector Q, it is necessary to clamp from the upper and lower surfaces of one end of the cut protector Q. The lower clamp 202 is used to clamp the lower surface of the outer end of the cut protector Q.

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

[0046] Multiple notches 202a are provided and 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 notch 202a away from the center of the fixed cylinder 100, while the L-shaped plate 202c is located inside the rotating plate 202b. The arc-shaped stop bar 202d is used to restrict the rotation of the L-shaped plate 202c. The edge of the arc-shaped groove 202e has an arc edge to prevent the L-shaped plate 202c from being jammed by the arc-shaped stop bar 202d when it rotates.

[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 formed on the side of the L-shaped plate 202c. The L-shaped slider 202g is slidably disposed on the inner side of the L-shaped groove 202f. The two ends of the spring 202h are respectively fixedly disposed on the side of the L-shaped slider 202g and the inner side of the L-shaped groove 202f. The silicone pad 202i is fixedly disposed on the end of the L-shaped slider 202g away from the rotating plate 202b. 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 side part of the L-shaped plate 202c respectively. The L-shaped slider 202g can fit the shape of the L-shaped groove 202f and slide in it. The spring 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 202a through the torsion spring, so it can be rotated and reset.

[0049] The function of the silicone pad 202i is to protect the patient's wound. Since the lower clamp 202 may come into contact with the patient's surgical incision, protective measures are required. First, the silicone pad 202i itself is made of soft material, which can protect the patient's wound from secondary damage. Second, when the fixation device is not used, the silicone pad 202i is located inside the L-shaped groove 202f, thus playing a role in preventing dust and bacteria.

[0050] When not in use, the L-shaped slider 202g and the L-shaped groove 202f fit together, 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 towards 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 fixing ring 203a, a bending rod 203b, a fixing plate 203c, and a limiting frame 203d. The fixing ring 203a is sleeved on the side of the fixing cylinder 100 and rotatably mounted on the top of the adjusting screw ring 201. The bending rod 203b is fixedly mounted on the top of the fixing ring 203a. The limiting frame 203d is fixedly mounted on the end of the bending rod 203b and is fixedly mounted on the inner side of the fixing cylinder 100. The bending rod 203b is slidably mounted on the inner wall of the limiting frame 203d. Multiple sets of upper clamps 203 and lower clamps 202 are provided, and the upper clamps 203 and lower clamps 202 are arranged alternately.

[0052] The advantage of the staggered arrangement is that when the upper clamp 203 and the lower clamp 202 approach each other, they will compress the upper and lower surfaces of the incision protector Q. Since the incision protector Q is made of silicone, it will be deformed by compression, which will eventually cause the fixing plate 203c of the upper clamp 203 and the L-shaped plate 202c of the lower clamp 202 to be staggered and flush. This increases the clamping force and keeps the end face of the incision protector Q flush, preventing the patient from experiencing any discomfort at the incision site.

[0053] The limiting member 204 includes a square frame 204a and a tightening strap 204b. The square frame 204a is fixedly installed at the bottom of the fixing cylinder 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 fixing cylinder 100, and their ends are connected to buckles for connecting the two tightening straps 204b together.

[0054] When in use: After the incision protector Q is placed on the patient's wound, the medical staff will bring the fixation 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 will hold the fixation cylinder 100 with one hand and rotate the adjusting screw ring 201 with the other hand. The adjusting screw ring 201 will move along the axis of the fixation cylinder 100 under the action of the thread. During the movement, the bottom of the adjusting screw ring 201 presses against the rotating plate 202b, which in turn presses against the L-shaped slider 202g and the L-shaped plate 202c. This causes the L-shaped plate 202c to move the L-shaped slider 202g closer to the fixed cylinder 100, where it is finally stopped by the arc-shaped stop bar 202d. At the same time, the fixed ring 203a moves the bending bar 203b and the fixed plate 203c downwards. Under the alternating pressure of the upper clamp 203 and the lower clamp 202, the fixed cylinder 100 and the incision protector Q are successfully connected. Finally, the tightening strap 204b is wrapped around the patient's chest and then tightened, thus completing the connection between the fixation device and the incision protector Q, as well as the stabilization of the fixation device itself.

[0055] The remaining structure is the same as that in Example 1.

[0056] Example 3

[0057] Reference Figures 7-8This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the fixation frame 301 is the main means of restricting the thoracoscope. The hole in the center of the fixation frame 301 is larger than the hole of the incision protector Q. The directional component 302 is used to realize the multi-axis rotation of the fixation frame 301, and the adjusting component 303 is used to realize the adaptive clamping of the fixation frame 301 for thoracoscopes of different sizes.

[0058] The directional component 302 includes a first rotating ring 302a and a second rotating ring 302b. The first rotating ring 302a is rotatably disposed inside the fixed cylinder 100, and the second rotating ring 302b is rotatably disposed inside the first rotating ring 302a via a rotating shaft. The fixed frame 301 is rotatably disposed inside the rotating ring via a rotating shaft. The rotation centers of the second rotating ring 302b and the fixed frame 301 are perpendicular.

[0059] The adjusting component 303 includes a lifting slide rod 303a, a connecting ring 303b, a moving ring 303c, a rubber concave block 303d, a rubber protrusion 303e, and a compression ring 303f. The lifting slide rod 303a passes through and slides along the inner and outer sides of the fixed frame 301. The connecting ring 303b is located outside the fixed frame 301 and fixedly mounted at the end of the lifting slide rod 303a. The moving ring 303c is rotatably mounted on top of the connecting ring 303b. The compression ring 303f is located inside the fixed frame 301 and fixedly mounted at the end of the lifting slide rod 303a. The rubber protrusion 303e is fixedly mounted inside the moving ring 303c, and the rubber concave block 303d is fixedly mounted outside the fixed frame 301. The rubber protrusion 303e and the rubber concave block 303d are in a tight-fitting state when connected.

[0060] The lifting slide bar 303a has several sections evenly distributed on the upper surface of the fixed frame 301. The compression ring 303f is only one and is connected to the 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] The adjusting component 303 also includes a movable slide plate 303g, a curved plate 303h, a stop plate 303i, and a second spring 303j. The movable slide plate 303g is slidably disposed on the inner and outer sides of the center of the fixed frame 301. The curved plate 303h and the stop plate 303i are fixedly disposed at both ends of the movable slide plate 303g. The inner side of the compression ring 303f is slidably disposed on the side of the curved plate 303h. The second spring 303j is fixedly disposed on the side of the curved plate 303h and the inner side of the fixed frame 301, respectively. The second spring 303j is used to reset the movable slide plate 303g after it has moved.

[0062] In use: First, insert the thoracoscope into the fixation frame 301. The thoracoscope passes through the incision protector Q and enters the patient's thoracic cavity. Then, the medical staff pushes the moving ring 303c, which drives the connecting ring 303b to move downward. During the downward movement, the compression ring 303f compresses the curved plate 303h, which in turn compresses the moving slide plate 303g. The moving slide plate 303g then drives the abutment plate 303i to move closer to the thoracoscope. Finally, multiple abutment plates 303i restrict the thoracoscope to the center of the fixation frame 301. Then, the moving ring 303c can be rotated. The rubber convex and concave plates fix the moving ring 303c. Here, the abutment plate 303i only contacts the thoracoscope and plays a limiting role, but does not fix the thoracic cavity. In actual use, the medical staff can use the directional component 302 to achieve multi-axis rotation of the thoracoscope and also to achieve its axial movement.

[0063] Therefore, after using the fixation device, medical staff can not only operate the thoracoscope flexibly, but also limit the position of thoracoscopes of different sizes by adjusting the moving ring 303c.

[0064] The remaining structure is the same as that in Example 2.

[0065] Example 4

[0066] Example 4 is a further improvement based on Examples 2 and 3. In order to improve aseptic operation and reduce direct contact between the tightening band 204b and the patient's body, when fixing the fixation device itself, the tightening band 204b can also wrap around the operating table once before clamping, thus stabilizing the fixation device itself.

[0067] Preferably, the limiting member 204 also includes a fastener, on which the tightening band 204b is threaded and movable. The fastener can also be anchored to the operating table and used to tighten the tightening band 204b. In use, the tightening band 204b is first wrapped around the operating table, and the two tightening bands 204b are connected together by the buckle at the end of the tightening band 204b to initially fix the fixation device itself. Then, the fastener is anchored to the operating table and the tightening band 204b is tightened to further fix the fixation device itself. Through the double fastening of the buckle and the anchor, the stability of the fixation device itself is further improved, the large movement of the fixation device itself during surgery is reduced, the reliability of the fixation device for fixing the thoracoscope is improved, and thus the quality of surgery is improved.

[0068] Preferably, such as Figure 9As shown, the fastener includes an anchoring clip 400 and a tightening mechanism 500. The anchoring clip 400 is used to anchor the device onto the operating table. The tightening mechanism 500 is disposed on the anchoring clip 400 and passes through the tension band 204b, and is used to tighten the tension band 204b, thereby further securing the device itself.

[0069] Preferably, the anchoring clip 400 is a fixing clip in the prior art.

[0070] Preferably, such as Figure 10 As shown, the tightening mechanism 500 includes an outer cylinder 510, a tightening band clamping assembly 520, and a tightening band tightening assembly 530. The outer cylinder 510 is fixedly connected to the anchoring clamp 400. The tightening band clamping assembly 520 is disposed on the tightening band tightening assembly 530 and is used to clamp the tightening band 204b. The tightening band tightening assembly 530 is disposed inside the outer cylinder 510 and is rotatably connected to the outer cylinder 510. The tightening band tightening assembly 530 is used to tighten the tightening band 204b. In use, the tightening band 204b is clamped by the tightening band clamping assembly 520 and then tightened by the tightening band tightening assembly 530, thereby further fixing the fixing device itself.

[0071] Preferably, the outer cylinder 510 is provided with a first through hole, which is used to pass through the tightening strap 204b.

[0072] Preferably, such as Figure 11 As shown, the tensioning strap clamping assembly 520 includes clamping bars 521, a return spring 522, and a control knob 523.
