Description

Technical Field

[0001] This utility model relates to the field of thoracoscopic surgical instruments, and in particular to a thoracoscopic fixation device for thoracoscopic surgery. Background Technology

[0002] Thoracoscopic surgery is a common minimally invasive surgery in the medical field today. Existing laparoscopes generally include a tube with a lens and a transmission fiber optic cable. During the operation, the doctor holds the tube and inserts the lens into the patient's body through the incision. The transmission fiber optic cable projects the patient's internal condition onto a display screen for the doctor to perform the operation.

[0003] Currently, during thoracoscopic surgery, in order to avoid medical staff having to hold the thoracoscopic tube throughout the entire procedure, a special fixing device is used to fix the tube. However, as the surgery progresses, the insertion depth and angle of the tube will change, and the traditional fixing device for thoracoscopic surgery is not convenient for medical staff to make flexible micro-adjustments.

[0004] Therefore, it is necessary to provide a new thoracoscopic fixation device for thoracoscopic surgery to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a thoracoscopic fixation device for thoracoscopic surgery that allows medical staff to flexibly adjust the insertion depth and angle of the endoscope tube according to the needs of the surgery.

[0006] To solve the above-mentioned technical problems, the present invention provides a thoracoscopic fixation device for thoracoscopic surgery, comprising: a second cantilever and an adjustment assembly, the adjustment assembly including a support member, a first damping shaft installed between the second cantilever and the support member, a mounting member rotatably connected to one end of the support member relative to the second cantilever via the second damping shaft, a worm gear rotatably connected to one side wall surface of the mounting member relative to the side wall surface of the support member, a worm wheel meshing at the bottom of the worm gear, the worm wheel rotatably connected to the mounting member, a gear fixedly connected to one side wall surface of the worm wheel, and a rack meshing on one side of the gear;

[0007] The rack has a limiting groove on its surface, and a limiting block is slidably connected inside the limiting groove. The limiting block is fixedly connected to the mounting component through a connecting plate. A limiting sleeve is fixedly connected to one side wall surface of the rack relative to the gear, and two limiting sleeves are longitudinally distributed on the surface of the rack.

[0008] As a further embodiment of this utility model, a fastening bolt is threaded onto one side wall surface of the limiting sleeve, and a mirror tube is provided on the inner side of the two limiting sleeves, with the end of the fastening bolt abutting against the surface of the mirror tube.

[0009] Through the above technical solution, in this device, medical staff can adjust the angle and end height of the endoscope tube according to the progress of the surgery or real-time needs. If it is necessary to adjust the left and right swing angle during operation, the support component is rotated. Since the first damping shaft is set between the support component and the second cantilever, the structure can stop as needed. Similarly, when adjusting the pitch angle of the endoscope tube, it can be done by rotating the mounting component on one side of the second damping shaft. Afterwards, if it is necessary to change the height of the bottom of the endoscope tube, the adjustment knob is rotated. The worm gear and worm shaft drive the gear to rotate, thereby changing the height of the meshing rack. Due to the self-locking characteristics of the worm gear and worm shaft, the rack and the endoscope tube fixed on its surface will be fixed at that height. This structural design makes it convenient for medical staff to adjust and easy to use.

[0010] As a further embodiment of this utility model, a column is provided on one side of the second cantilever, a base is fixedly connected to the bottom of the column, and a number of universal wheels evenly distributed around the axis are fixedly connected to the outer wall surface of the base.

[0011] With the above technical solution, the user can use the casters to move the device to a suitable position on the side of the operating table.

[0012] As a further embodiment of this utility model, an electric telescopic rod is fixedly connected to one side wall surface of the column, a sliding sleeve is fixedly connected to the output end of the electric telescopic rod, and a plurality of movable brackets evenly distributed around the axis are fixedly connected to the outer surface of the sliding sleeve, and anti-slip pads are glued to the bottom of the plurality of movable brackets.

[0013] With the above technical solution, after the structure is moved to the correct position, the electric telescopic rod can be activated to move several movable supports down until the anti-slip pads at the bottom of the supports are in full contact with the ground, thereby fixing the position of the structure and preventing it from moving by the casters.

[0014] As a further embodiment of this utility model, the surface of the column is slidably connected to a first sliding member, a first locking bolt is threadedly connected to one side wall surface of the first sliding member, and a first cantilever is fixedly connected to one end of the first sliding member relative to the first locking bolt.

[0015] By adjusting the height of the first sliding member on the column, the overall distance between the component and the patient's body can be adjusted, so that the endoscope tube fixed in the limiting sleeve can be at a suitable height. After adjustment, the first locking bolt can be tightened to fix it on the column.

[0016] As a further embodiment of this utility model, a second sliding member is slidably connected to the surface of the first cantilever, a second locking bolt is threadedly connected to one side wall surface of the second sliding member, and one end of the second sliding member relative to the second locking bolt is fixedly connected to the end of the second cantilever.

[0017] With the above technical solution, by adjusting the position of the second sliding member on the first cantilever, medical staff can move the endoscope tube laterally to the area on the patient's body where surgery is needed. Then, the second locking bolt can be tightened to fix it on the first cantilever. This structural design makes it convenient for medical staff to adjust.

[0018] As a further embodiment of this utility model, an adjustment knob is fixedly connected to the end of the worm gear, and a limit plate is fixedly connected to the top of the column and the end of the first cantilever away from the first sliding member.

[0019] The above technical solution enables the setting of a limiting plate to prevent the first and second sliding parts from detaching from the surfaces of the column and the first cantilever.

[0020] Compared with related technologies, the thoracoscopic fixation device for thoracoscopic surgery provided by this utility model has the following advantages:

[0021] 1. In this utility model, the device allows medical personnel to adjust the angle and end height of the endoscope tube according to the progress of the surgery or real-time needs. If it is necessary to adjust the left and right swing angle during operation, the support member is rotated. Since a first damping shaft is set between the support member and the second cantilever, the structure can stop as needed. Similarly, when adjusting the pitch angle of the endoscope tube, it can be done by rotating the mounting member on one side of the second damping shaft. If it is necessary to change the height of the bottom of the endoscope tube, the adjustment knob is rotated. The gear is driven to rotate through the cooperation of the worm gear and worm, thereby changing the height of the rack meshing with it. Due to the self-locking characteristics of the worm gear and worm, the rack and the endoscope tube fixed on its surface will be fixed at that height. This structural design makes it convenient for medical personnel to adjust and easy to use.

[0022] 2. In this utility model, the user can move the device to a suitable position on the side of the operating table using the casters. After the structure is moved to the correct position, the electric telescopic rod can be activated to move several movable supports down until the anti-slip pads at the bottom are in full contact with the ground, thereby fixing the position of the structure and preventing it from moving via the casters. Then, by adjusting the height of the first sliding member on the column, the overall distance between the component and the patient's body can be adjusted, so that the endoscope tube fixed in the limiting sleeve can be at a suitable height. After adjustment, the first locking bolt can be tightened to fix it on the column. By adjusting the position of the second sliding member on the first cantilever, medical staff can move the endoscope tube laterally to the area on the patient's body where surgery is needed. Then, the second locking bolt can be tightened to fix it on the first cantilever. This structural design allows medical staff to make flexible adjustments. Attached Figure Description

[0030] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a thoracoscopic fixation device for thoracoscopic surgery according to the present invention; Figure 2 This is a partial structural diagram of a thoracoscopic fixation device for thoracoscopic surgery according to the present invention. Figure 1 ; Figure 3 This is a partial structural diagram of a thoracoscopic fixation device for thoracoscopic surgery according to the present invention. Figure 2 ; Figure 4 This is a partial structural diagram of a thoracoscopic fixation device for thoracoscopic surgery according to the present invention. Figure 3 A thoracoscopic fixation device for thoracoscopic surgery includes:

[0031] The second cantilever 6 and the adjustment assembly 7 include a support member 16. A first damping shaft 15 is installed between the second cantilever 6 and the support member 16. One end of the support member 16 relative to the second cantilever 6 is rotatably connected to a mounting member 17 via the second damping shaft 23. A worm gear 25 is rotatably connected to one side wall surface of the mounting member 17. A worm wheel 18 is meshed at the bottom of the worm gear 25. The worm wheel 18 is rotatably connected to the mounting member 17. A gear 27 is fixedly connected to one side wall surface of the worm wheel 18. A rack 19 is meshed on one side of the gear 27.

[0032] A limiting groove 20 is formed on the surface of the rack 19. A limiting block 21 is slidably connected inside the limiting groove 20. The limiting block 21 is fixedly connected to the mounting part 17 through a connecting plate. A limiting sleeve 22 is fixedly connected to one side wall surface of the rack 19 relative to the gear 27. There are two limiting sleeves 22 located longitudinally on the surface of the rack 19.

[0033] like Figure 1-4 As shown, a fastening bolt 26 is threadedly connected to one side wall surface of the limiting sleeve 22, and a mirror tube 8 is provided on the inner side of the two limiting sleeves 22. The end of the fastening bolt 26 abuts against the surface of the mirror tube 8.

[0034] In this device, medical staff can adjust the angle and end height of the endoscope tube 8 according to the progress of the surgery or real-time needs. If it is necessary to adjust the left and right swing angle during operation, the support member 16 is rotated. Since the support member 16 and the second cantilever 6 are provided with the first damping shaft 15, the structure can be stopped and started. Similarly, when adjusting the pitch angle of the endoscope tube 8, it can be done by rotating the mounting member 17 on one side of the second damping shaft 23. If it is necessary to change the height of the bottom of the endoscope tube 8, the adjustment knob 24 is rotated. Through the cooperation of the worm gear 18 and the worm 25, the gear 27 is driven to rotate, thereby changing the height of the rack 19 meshing with it. Due to the self-locking characteristics of the worm gear 18 and the worm 25, the rack 19 and the endoscope tube 8 fixed on its surface will be fixed at that height. This structural design makes it convenient for medical staff to adjust and easy to use.

[0035] like Figure 1-4 As shown, a column 2 is provided on one side of the second cantilever 6, and a base 1 is fixedly connected to the bottom of the column 2. Several universal wheels 13 evenly distributed around the axis are fixedly connected to the outer wall surface of the base 1.

[0036] The user can move the device to a suitable position on the side of the operating table using the casters 13.

[0037] like Figure 1-4 As shown, an electric telescopic rod 9 is fixedly connected to one side wall surface of the column 2. A sliding sleeve is fixedly connected to the output end of the electric telescopic rod 9. Several movable supports 10 evenly distributed around the axis are fixedly connected to the outer surface of the sliding sleeve. Anti-slip pads 14 are glued to the bottom of each of the movable supports 10.

[0038] After the structure is moved to the correct position, the electric telescopic rod 9 can be activated to move several movable supports 10 down until the anti-slip pads 14 at the bottom of the supports are in full contact with the ground, thereby fixing the position of the structure and preventing it from moving via the casters 13.

[0039] like Figure 1-4 As shown, a first sliding member 3 is slidably connected to the surface of the column 2, and a first locking bolt 11 is threadedly connected to one side wall surface of the first sliding member 3. A first cantilever 4 is fixedly connected to one end of the first sliding member 3 relative to the first locking bolt 11.

[0040] By adjusting the height of the first sliding member 3 on the column 2, the overall distance between the component 7 and the patient's body can be adjusted, so that the endoscope tube 8 fixed in the limiting sleeve 22 can be at a roughly suitable height. After adjustment, the first locking bolt 11 can be tightened to fix it on the column 2.

[0041] like Figure 1-4 As shown, a second sliding member 5 is slidably connected to the surface of the first cantilever 4, and a second locking bolt 12 is threadedly connected to one side wall surface of the second sliding member 5. One end of the second sliding member 5 relative to the second locking bolt 12 is fixedly connected to the end of the second cantilever 6.

[0042] By adjusting the position of the second sliding member 5 on the first cantilever 4, medical staff can move the endoscope 8 laterally to the area on the patient's body where surgery is needed. Then, the second locking bolt 12 can be tightened to fix it on the first cantilever 4. This structural design makes it convenient for medical staff to adjust.

[0043] like Figure 1-4 As shown, an adjustment knob 24 is fixedly connected to the end of the worm gear 25, and a limit plate is fixedly connected to the top of the column 2 and the end of the first cantilever 4 away from the first sliding member 3.

[0044] Setting a limiting plate can prevent the first sliding member 3 and the second sliding member 5 from detaching from the surface of the column 2 and the first cantilever 4.

[0045] The working principle of the thoracoscopic fixation device for thoracoscopic surgery provided by this utility model is as follows:

[0046] First step: In this device, medical staff can adjust the angle and end height of the endoscope tube 8 according to the progress of the surgery or real-time needs. If it is necessary to adjust the left and right swing angle during operation, the support member 16 is rotated. Since the support member 16 and the second cantilever 6 are provided with the first damping shaft 15, the structure can stop and start. Similarly, when adjusting the pitch angle of the endoscope tube 8, it can be done by rotating the mounting member 17 on one side of the second damping shaft 23. After that, if it is necessary to change the height of the bottom of the endoscope tube 8, the adjustment knob 24 is rotated. Through the cooperation of the worm wheel 18 and the worm 25, the gear 27 is driven to rotate, thereby changing the height of the rack 19 meshing with it. Due to the self-locking characteristics of the worm wheel 18 and the worm 25, the rack 19 and the endoscope tube 8 fixed on its surface will be fixed at this height. This structural design makes it convenient for medical staff to adjust and easy to use.

[0047] The second step: The user can move the device to a suitable position on the side of the operating table using the casters 13. After the structure is moved to the correct position, the electric telescopic rod 9 can be activated to move several movable supports 10 down until the anti-slip pads 14 at the bottom are in full contact with the ground, thereby fixing the position of the structure and preventing it from moving using the casters 13. Then, by adjusting the height of the first sliding member 3 on the column 2, the overall distance between the component 7 and the patient's body can be adjusted, so that the endoscope tube 8 fixed in the limiting sleeve 22 can be at a suitable height. After adjustment, the first locking bolt 11 can be tightened to fix it on the column 2. By adjusting the position of the second sliding member 5 on the first cantilever 4, the medical staff can move the endoscope tube 8 laterally to the area on the patient's body where surgery is needed. Then, the second locking bolt 12 can be tightened to fix it on the first cantilever 4. This structural design allows the medical staff to adjust it flexibly.

[0048] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
