Such minimally invasive surgery has the advantages of small trauma and rapid postoperative recovery, but puts forward higher requirements for the precise control and stable placement of surgical devices. During the operation, multiple special devices are needed, including thoracoscope lens, forceps, cutting and suturing device, suction tube, etc. Most of the devices need to be kept at a specific position and angle in the operation space to cooperate with the operator to complete the core operations such as tissue separation, resection and hemostasis. When fixing the thoracoscope lens, a fixing device is needed for fixation.

The tip angle adjustment structure adopts a combination design of suction blocks and fixing valve blocks, allowing the tip to be adjusted to correct the angle with the fine adjustment of the suction blocks and fixing valve blocks, ensuring precise positioning of the surgical field.

Detailed Implementation

[0030] Examples, such as Figures 1 to 2 As shown, the present invention relates to a fixation device for lung surgical instruments, comprising a support assembly 1, an operating end fixation assembly 2, and a head end fixation assembly 3; the operating end fixation assembly 2 is installed on the adjustable end of the support assembly 1, the support assembly 1 is used to support the operating end fixation assembly 2, and control the position and height of the operating end fixation assembly 2; the adjustable end of the head end fixation assembly 3 is connected to the bottom end of the operating end fixation assembly 2; when in use, the operating end fixation assembly 2 is located at the operating end of the thoracic endoscope, and is used to fix the operating end of the thoracic endoscope and assist the operator in controlling the position of the operating end of the thoracic endoscope; when in use, the head end fixation assembly 3 is located at the head end of the thoracic endoscope, and the head end fixation assembly 3 is fixed to the head end of the thoracic endoscope by a detachable structure, and is used to fix the head end of the thoracic endoscope and assist the operator in controlling the head end of the thoracic endoscope.

[0031] The support assembly 1 includes a vehicle body 101 and a first adjustable crank arm 102, which is mounted on the vehicle body 101.

[0032] This invention, through the design of a support component 1, an operating end fixing component 2, and a head end fixing component 3, achieves bidirectional independent support and fixation of the operating end and head end of a thoracic endoscope, while also considering overall operational adaptability. It solves the problem of traditional fixation devices relying on a single support point and being unable to stabilize both ends separately. The support component 1 uses the vehicle body 101 as a stable moving base, with the first adjustable curved arm 102 as the core support structure. Its adjustable end is directly connected to the operating end fixing component 2. This connection method allows the operating end fixing component 2 to independently complete support and fixation without relying on the head end. The first adjustable curved arm 102 can be adjusted through multiple joints to precisely position the operating end fixing component 2 at a height and angle convenient for the surgeon to hold. The fixing structure of the operating end fixing component 2 itself can also independently clamp the endoscope operating end, limiting its radial rotation and axial displacement. Even if the head end is not fully fixed, it can still ensure a stable grip of the operating end, facilitating the surgeon to adjust the operating posture and initial instrument position beforehand. The head end fixing assembly 3 is connected with the operation end fixing assembly 2 through an adjustable end, but the adjustment structures of the two are independent of each other, the adjustable end of the head end fixing assembly 3 can be adjusted in length and angle independently, and the position calibration of the head end can be realized without linkage operation end fixing assembly 2; and the separable fixing structure of the head end and the endoscope can separately complete clamping and releasing of the head end under the premise that the operation end is fixed, and can independently bear external force generated by the head end due to breathing movement and instrument collision after being fixed, so as to avoid transmission of the external force to the operation end and affect the operation of the operator, and ensure the stability of the view of the head end in the chest cavity. The independent support design of the operation end and the head end is not completely separated, but forms a cooperative relationship of basic fixing and distal end adaptation through the operation end fixing assembly 2: the operation end fixing assembly 2 realizes proximal end stability relying on the support assembly 1, and provides a reference for the head end fixing assembly 3; the head end fixing assembly 3 realizes distal end precision through independent adjustment, and makes up for the position deviation of the head end that cannot be covered by the operation end. Both the shaking caused by the traditional device of one end fixed and the other end followed, and the requirement of the endoscope in lung surgery that the position of the two ends needs to be frequently adjusted can be flexibly adapted, so that the stability and flexibility of the operation are greatly improved.

[0033] Specifically, as shown in Figures 1 to 6 The operation end fixing assembly 2 comprises a fixed ball head 201 and an operation end angle adjustment structure 202; a fixed soft pad 2011 is arranged in the middle hole of the fixed ball head 201, and the fixed soft pad 2011 is used for clamping the operation end of the chest endoscope inserted into the middle hole of the fixed ball head 201; the operation end angle adjustment structure 202 comprises a fixed ball sleeve 2021, three first stop air bags 2022, a first air pipe 2023 and a first inflation pedal 2024; the fixed ball head 201 is movably connected in the fixed ball sleeve 2021, the three first stop air bags 2022 are equidistantly arranged in the fixed ball sleeve 2021, the first air pipe 2023 is connected with the three first stop air bags 2022, and the other end of the first air pipe 2023 is connected with the first inflation pedal 2024, and the first inflation pedal 2024 is connected with the vehicle body 101.

[0034] The surface of the fixed ball head 201 is provided with fifty stop recesses 2012, and the surfaces of the three first stop air bags 2022 are each provided with a stop convex point 2025.

[0035] The head end angle adjustment structure 303 comprises an adsorption block 3031 and a fixed petal block 3032; the five adsorption blocks 3031 are respectively arranged at the head end of the five tooth rods 3025, and the five adsorption blocks 3031 form a ball sleeve structure; the adsorption block 3031 and the fixed petal block 3032 are respectively made of a magnet and a corresponding metal block; the five fixed petal blocks 3032 are respectively arranged on one side of the five adsorption blocks 3031, and the five fixed petal blocks 3032 form a ball head structure, and the ball head structure is used for fixing the head end of the chest endoscope.

[0036] The present application realizes accurate fixing and flexible adjustment of the two ends of the chest endoscope by the fine design of the operation end fixing assembly 2 and the head end angle adjustment structure 303, further improving the stability and convenience of the operation; in the operation end fixing assembly 2, the fixed soft pad 2011 in the middle of the fixed ball head 201 can tightly clamp the operation end of the endoscope, which can not only avoid damage to the instrument caused by rigid clamping, but also prevent the operation end from sliding; the movable connection of the fixed ball head 201 and the fixed ball sleeve 2021 gives the operation end multi-angle adjustment capability, and the operator can flexibly adjust the inclination direction of the operation end according to the operation requirements. When adjusted to the appropriate angle, step on the first inflation pedal 2024, inflate the three equidistantly distributed first stop air bags 2022 through the first air supply pipe 2023, and the stop convex points 2025 on the surface of the air bag will be embedded into the stop concave groove 2012 on the surface of the fixed ball head 201, forming multi-point occlusion fixation. This physical locking method responds quickly and is fixed reliably, and does not need complex electronic control to stably maintain the angle of the operation end, freeing the operator's hand strength while ensuring that the operation end does not deviate accidentally.

[0037] The head end angle adjustment structure 303 adopts the combined design of five groups of adsorption blocks 3031 and fixed flap blocks 3032, the ball sleeve structure composed of five adsorption blocks 3031 can fit the curved surface of the endoscope head, and the ball head structure formed by cooperating with the fixed flap block 3032 realizes all-around wrapping and fixing, which can adapt to different specifications of the endoscope head, and can also disperse the fixing force through the coordinated action of the five components to avoid damage to the head end due to excessive local stress. This design allows the head end to be adjusted in angle based on independent fixing, ensuring accurate positioning of the surgical field, while the adjustment structure of the operation end forms a response, so that the two ends of the endoscope can be independently fixed and adjusted to meet the needs of complex surgical scenes.

[0038] The combination of the air bag locking of the operation end and the flap block fixing of the head end constructs a double protection system of flexible clamping and rigid positioning, which not only retains the flexibility of instrument adjustment, but also realizes stable fixing through the precise cooperation of mechanical structure, effectively improving the accuracy and safety of endoscope operation in lung surgery.

[0039] It is worth mentioning that, as Figures 9 to 10As shown, the head end fixing assembly 3 of the present application comprises a second adjustable curved arm 301, a head end fixing structure 302 and a head end angle adjusting structure 303; the second adjustable curved arm 301 is connected with a mounting rack 5011, the head end fixing structure 302 comprises a fixing ring 3021, a first rotary drive 3022, transmission members 3023, gear wheels 3024, toothed rods 3025 and a through slot 3026; the fixing ring 3021 is installed on the second adjustable curved arm 301, the first rotary drive 3022 is installed on the fixing ring 3021, the first rotary drive 3022 drives the five gear wheels 3024 to rotate in cooperation with the four transmission members 3023, and the five gear wheels 3024 are arranged in a ring shape, the five toothed rods 3025 are respectively meshed and connected on one side of the five gear wheels 3024, and the five toothed rods 3025 are all slidingly connected on the fixing ring 3021, one side of the fixing ring 3021 is provided with the through slot 3026, and the through slot 3026 is used for enabling the head end of the thoracic endoscope to pass through.

[0040] The transmission member 3023 comprises two transmission wheels and a transmission belt connecting the transmission wheels.

[0041] The present application realizes stable clamping and accurate control of the head end of the endoscope through precise transmission and cooperative adjustment design of the head end fixing assembly 3, and provides a reliable distal instrument fixing solution for lung surgery; the second adjustable curved arm 301 is matched with the mounting rack 5011 to form an independent support adjusting system, which can flexibly adjust the spatial position of the head end fixing structure 302, ensure accurate alignment with the head end of the endoscope, and its independent adjusting characteristic does not affect the control of the operation end, meeting the requirement of adjusting the two ends respectively during surgery.

[0042] In the head end fixing structure 302, the fixing ring 3021 serves as a bearing base and integrates an efficient transmission clamping mechanism; the first rotary drive 3022 drives the five ring-shaped arranged gear wheels 3024 to rotate synchronously through the four transmission members 3023, and then drives the meshed five toothed rods 3025 to slide along the fixing ring 3021, and the advantage of this transmission design is that, by means of the flexible transmission characteristic of the transmission belt, uniform distribution of power can be realized in the ring-shaped space, ensuring synchronous rotation of the five gear wheels 3024, so that the toothed rods 3025 realize high-precision cooperative extension and contraction, when the head end needs to be fixed, the toothed rods 3025 synchronously approach from five directions, and the endoscope body is formed in a ring-shaped clamping manner, which not only ensures uniform distribution of clamping force, but also can adapt to head ends of different diameters; when it needs to be loosened or adjusted, the toothed rods 3025 are synchronously retracted, and the operation is convenient and efficient; when the head end needs to be taken out, the head end is taken out through the through slot 3026.

[0043] The independent support adjustment and synchronous ring clamping design makes the head end fixing assembly 3 not only stable and fixed to eliminate slight shaking during surgery, but also flexible to meet the needs of different surgical sites, and the operating end fixing assembly 2 forms a echo, together to improve the stability and accuracy of the endoscope operation in lung surgery.
