Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an auxiliary support device for endoscopic surgery. Background Technology

[0002] Endoscopes are tools used for observation and manipulation during surgical procedures. Due to their advantages such as eliminating blind spots during surgery, precise localization with the aid of stereotactic or neuronavigation technology, ability to treat areas difficult to reach with conventional surgery, suitability for minimally invasive approaches, low surgical invasiveness, and fewer surgical complications, endoscopes are increasingly favored by surgeons. Furthermore, endoscopic surgery has become one of the main development directions in modern minimally invasive neurosurgery.

[0003] (1) When doctors perform endoscopic craniotomy or thoracotomy, they need to use surgical instruments such as endoscopes and suction devices. During the operation, when using an endoscope, the surgeon usually has difficulty finding a stable support point to perform the operation, which causes the endoscope to shake and the transmitted image to shake, affecting the efficiency of the operation and creating certain safety hazards.

[0004] (2) Some lesions are in the superficial part, but still require endoscopic operation to complete the surgery. The lesion site and the endoscope are difficult to form an operable cavity, and cannot provide the surgeon with a comfortable operating space. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary support device for endoscopic surgery to solve the problems mentioned in the background art. This invention addresses the current situation where the lack of a stable support point for endoscopes during surgery forces surgeons to expend considerable effort searching for a stable operating platform, and requires extra caution to avoid unnecessary damage to patient tissues caused by endoscope movement.

[0006] The development of this invention can greatly improve the comfort of endoscopic operation, save surgeons energy, and allow them to focus more on completing the surgical operation more safely and efficiently. At the same time, the water injection chamber structure of this device can provide surgeons with the convenience of rinsing the surgical area without removing the endoscope.

The inner side wall of the sliding hole is provided with a sliding opening 1 evenly distributed. The inner wall of the sliding hole is provided with a telescopic cylinder. The telescopic cylinder includes a cylinder body and a plurality of guide strips fixed on the outer circumference of the cylinder body. The guide strips are slidably installed on the inner wall of the sliding opening 1. The external threaded cylinder is threadedly connected to the inner side wall of the cylinder body. The support plate assembly is installed on the end of the cylinder body away from the annular plate. A limiting plate is fixed at one end of the cylinder body. The limiting plate is located between the concave plate 2 and the fixing plate. The outer wall of the outer shell is provided with three through slots.

[0012] Preferably, the support plate assembly includes a fixed cylinder, the inner side wall of which is provided with equally spaced sliding openings II, the fixed cylinder is sleeved on the outer wall of the cylinder body, the guide strip is slidably installed on the inner wall of the sliding openings II, the ring is fixed with three small motors II, the output shaft of the small motors II is fixed with a threaded rod, and the threaded rod is threadedly connected to the inner wall of the threaded hole.

[0013] Preferably, the intermediate tube assembly includes an intermediate tube one, a spherical rotor one rotatably installed in the support hole, a rubber ring, an intermediate tube two, and a water storage bladder. The spherical rotor is fitted and fixedly installed on the outer middle section of the intermediate tube one near the rubber ring. The intermediate tube is fitted on the intermediate tube two. The intermediate tube one and the intermediate tube two are integrally formed, and a cylindrical gap is formed between them. The middle section of the intermediate tube one has an annular opening. The rubber ring is annular and has a water injection cavity inside. The longitudinal section of the rubber ring is H-shaped, and the water injection cavity is also H-shaped. The width of the opening is smaller than the width of the annular notch of the rubber ring. The end of the gap away from the water storage bladder is provided with several annularly distributed water outlet holes. The inner side of the rubber ring passes through the opening and is embedded in the gap. The water injection cavity is located in the gap and has an annular notch communicating with the gap on the side near the water outlet hole.

[0015] The support plate is integrally formed from two symmetrically arranged support plates. Each support plate has several through holes with a hemispherical structure. The diameter of one end of each through hole is larger than the diameter of the other end of the plate. The through holes of the two support plates are connected one-to-one and their larger ends are fitted together.

[0016] The support plate assembly also includes the support plate body, which is fixed to the outer wall of the fixed cylinder away from the cylinder body, and the support plate body has a threaded hole facing the outer wall of the fixed cylinder.

[0017] This invention provides an improved auxiliary support device for endoscopic surgery, which has the following improvements and advantages compared with the prior art:

[0018] Firstly, the small motor of this invention drives the bevel gear seven to rotate via the output shaft transmission shaft. The bevel gear seven drives the bevel gear four meshing with it to rotate, the bevel gear four drives the transmission rod two fixed to it to rotate, the driven transmission rod two drives the bevel gear five fixed to it to rotate, the rotation of bevel gear five drives the rotation of bevel gear six, and then the bevel gear six drives the bevel gear five meshing with it to rotate. The two bevel gears five rotate in opposite directions. Similarly, the transmission component one and the adjustment component one have similar structures, so the adjustment component one transmits power to the transmission component one. The internal movement of the transmission component one is the same. Thus, it can be seen that the external threaded cylinders in the adjustment component one, adjustment component two and adjustment component three rotate in the same direction. The external threaded cylinders can control the three cylinders to move outward or move synchronously and press against the bone edge through the threaded transmission, which better supports the endoscope, making it convenient and quick. Alternatively, the support plate body can be removed from the fixed cylinder and can be used with the serpentine arm. The entire device can move the endoscope to the surgical position without contacting the surgical wound, ensuring the smooth progress of the operation.

[0019] Secondly, the small motor 2 of the present invention rotates the threaded rod through the output shaft. The threaded rod controls the support plate body to move outward or inward through the threaded transmission. Since the three small motors 2 are set independently, the three support plate bodies can be controlled independently. Thus, fine adjustments can be made according to the surgical situation. In the case of irregular surgical wound, the endoscope can be moved to the optimal position by adjusting the position of the support plate body.

[0020] Thirdly, the intermediate tube assembly and side tube assembly of the present invention can freely adjust the viewing angle during surgery, ensuring the best viewing angle of the endoscope during surgery.

[0021] Fourthly, the water reservoir of this invention cleans the surgical area and endoscope lens with physiological saline through the gap and outlet of the intermediate tube assembly, which can ensure uniform cleaning of the endoscope from various angles and avoid blurring of the endoscope image. This not only improves the safety of endoscopic surgery, but also improves surgical efficiency.

[0022] Fifthly, the friction between the rubber flange one on the inner side of the middle tube two and the rubber flange two on the inner side of the side tube of the present invention can ensure that the endoscope will not rotate or slide arbitrarily after being adjusted to the optimal position, thus reducing the difficulty of operating the endoscope.

[0023] Sixthly, this invention, with its practical and ingenious design, provides better support and fixation for the endoscope, thus meeting the needs of the surgeon. In the increasingly widespread application of endoscopic technology in the surgical field, this device solves the current situation where endoscopes (especially neuroendoscopy) lack stable support points during surgery. This forces surgeons to expend considerable effort finding a stable and safe operating platform and to be extremely careful to avoid unnecessary damage to patient tissues caused by endoscope movement. With its compact design and refined internal operating structure, it provides a stable and reliable platform support for the endoscope while also incorporating irrigation and backup pathways, facilitating intraoperative endoscopic irrigation and drug administration. This reduces the number of times the endoscope needs to be adjusted during surgery, further improving the safety, reliability, accuracy, and efficiency of endoscopic surgery.

[0045] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] This invention provides an auxiliary support device for endoscopic surgery through improvements. The technical solution of this invention is as follows:

[0047] Example 1:

[0048] like Figures 1-18 As shown, an auxiliary support device for endoscopic surgery includes a housing. A circular ring plate 13 is fixed inside the housing. A bearing 21 is installed at the center of the circular ring plate 13. The outer ring of the bearing 21 is fixedly connected to the inner side of the circular ring plate 13. A support plate 22 is fixedly installed on the inner side of the bearing 21. Adjustment components 1-7, 2-17, and 3-18 are installed on the top of the circular ring plate 13. These components are evenly distributed on the top of the circular ring plate 13. A transmission component 1-6 is provided between adjustment components 1-7 and 2-18. A transmission component 2 16 is provided between 7. A drive component is installed on the top of the annular plate 13. A support hole 1 23 is opened at the center of the support plate 22. An intermediate tube component 4 is rotatably installed on the inner wall of the support hole 1 23. Multiple support holes 24 are opened at equal angles around the support hole 1 23 on the support plate 22. A side tube component is rotatably installed inside the support hole 24. Multiple support holes 24 are evenly distributed around the support hole 1 23. A support plate component shell is installed on the adjustment component 1 7, adjustment component 2 17 and adjustment component 3 18. 2. Both the support hole 1 23 and the support hole 24 are spherical through holes.

[0049] It should be noted here that the drive component can be connected to either the adjustment component three 18 or the adjustment component two 17. This embodiment does not limit this connection. Figure 3 and Figure 4 For example, the drive component is connected to the adjustment component 3 18. When the drive component is working, it can make the adjustment component 3 18 work. The adjustment component 3 18 drives the adjustment component 7 to work through the transmission component 1 6. The adjustment component 7 drives the adjustment component 2 17 to work through the transmission component 2 16. That is, the adjustment component 1 7, the adjustment component 2 17 and the adjustment component 3 18 work synchronously to open the support plate component 2 outward. The endoscope passes through the side tube component or the middle tube component 4 respectively. The viewing angle of the endoscope is adjusted by rotating the side tube component or the middle tube component 4 at the corresponding support hole 1 23 or support hole 2 24 respectively. The middle tube component 4 and the side tube component can adjust the viewing angle at will during the operation to ensure the best viewing angle of the endoscope during the operation.

[0050] The drive assembly includes a small motor 10, a drive shaft 11, and a bevel gear 12. The small motor 10 is fixed to the top of the annular plate 13. The output shaft of the small motor 10 is connected to one end of the drive shaft 11, and the other end of the drive shaft 11 is fixed to the bevel gear 12. The adjustment assemblies 1-7, 2-17, and 3-18 have the same specifications. Each of the adjustment assemblies 1-7, 2-17, and 3-18 includes two bevel gears 4-701 and two transmission rods 2-701. 702, two bevel gears 703, one bevel gear 704, and a concave plate 705. Rotation holes 1 are formed on the outer walls of both ends of the concave plate 705. A transmission rod 702 is rotatably mounted on the inner wall of the rotation hole 1. Bevel gears 701 and 703 are fixed to the two ends of the transmission rod 702. A rotation hole 2 is formed on the inner wall of the concave plate 705. An external threaded cylinder 19 is rotatably mounted on the inner wall of the rotation hole 2. The bevel gear 704 is fixed to the external threaded cylinder. On the outer wall of 19, bevel gear six 704 is coaxially arranged with the external threaded cylinder 19, and both bevel gear five 703 mesh with bevel gear six 704. One of the bevel gear four 701 in the adjusting assembly three 18 meshes with bevel gear seven 12. The transmission assembly one 6 and the transmission assembly two 16 have the same specifications. Both transmission assembly one 6 and transmission assembly two 16 include a concave plate one 601, a bevel gear one 602, two bevel gears two 603, and two transmission rods one 6. 04 and two bevel gears 605, the outer walls of both ends of the concave plate 601 are provided with rotating holes 3, the transmission rod 604 is rotatably installed on the inner wall of the rotating hole 3, the bevel gears 603 and 605 are respectively fixed at both ends of the transmission rod 604, the bevel gear 602 is rotatably installed on the inner wall of the concave plate 601, both bevel gears 603 mesh with bevel gears 602, and the bevel gears 605 mesh with the bevel gears 701 that are close to it.

[0051] like Figure 3 and Figure 4 For example, the small motor 10 drives the bevel gear 7 12 to rotate through the output shaft transmission shaft 11. The bevel gear 7 12 drives the bevel gear 4 701 that meshes with it to rotate. The bevel gear 4 701 drives the transmission rod 2 702 that is fixed to it to rotate. The driven transmission rod 2 702 drives the bevel gear 5 703 that is fixed to it to rotate. The rotation of the bevel gear 5 703 drives the bevel gear 6 704 to rotate. Then the bevel gear 6 704 drives the bevel gear 5 703 that meshes with it to rotate. The two bevel gears 5 703 rotate in opposite directions. Similarly, the transmission component 1 6 and the adjustment component 1 7 have similar structures. Therefore, the adjustment component 1 7 transmits power to the transmission component 1 6. The internal movement of the transmission component 1 6 is the same. It can be seen that the external threaded cylinder 19 in the adjustment component 1 7, the adjustment component 2 17 and the adjustment component 3 18 rotate in the same direction.

[0052] Furthermore, three fixing plates 20 are fixed on the annular plate 13. The outer wall of the fixing plate 20 is provided with a sliding hole. The inner side wall of the sliding hole is provided with a sliding opening 1 at equal intervals. The inner wall of the sliding hole is provided with a telescopic cylinder 5. The telescopic cylinder 5 includes a cylinder body 501 and multiple guide strips 502 fixed on the outer circumference of the cylinder body 501. The guide strips 502 are slidably installed on the inner wall of the sliding opening 1. The external threaded cylinder 19 is connected to the inner side wall of the cylinder body 501 by threads. The support plate assembly 2 is installed on the end of the cylinder body 501 away from the annular plate 13. One end of the cylinder body 501 is fixed with a limiting plate 503. The limiting plate 503 is located between the concave plate 2 705 and the fixing plate 20. The outer wall of the outer shell 1 is provided with three through slots. The three cylinder bodies 501 are respectively distributed in the three through slots. The external threaded cylinder 19 can control the three cylinder bodies 501 to move outward or inward through the form of threaded transmission. The setting of the sliding opening 1 and the guide strips 502 can prevent the cylinder body 501 from rotating.

[0053] The support assembly 2 includes a fixed cylinder 202. The inner wall of the fixed cylinder 202 has equally spaced sliding openings. The fixed cylinder 202 is sleeved on the outer wall of the cylinder body 501. The guide strip 502 is slidably installed on the inner wall of the sliding openings. Three small motors 14 are fixed to the ring 13. The output shaft of the small motors 14 is fixed with a threaded rod 15. The threaded rod 15 is threadedly connected to the inner wall of the threaded hole, so that it can be finely adjusted according to the surgical situation. One end of the fixed cylinder 202 can cooperate with the serpentine arm. The whole device moves the endoscope to the surgical position without contacting the surgical wound, ensuring the smooth progress of the operation.

[0054] Furthermore, the intermediate tube assembly 4 includes an intermediate tube 401, a spherical rotor 402 rotatably mounted in the support hole, a rubber ring 403, an intermediate tube 404, and a water reservoir 406. The spherical rotor 402 is sleeved and fixedly installed on the outer middle section of the intermediate tube 401 near the rubber ring 403. The intermediate tube 401 is sleeved on the intermediate tube 404. The intermediate tube 401 and the intermediate tube 404 are integrally formed, and a cylindrical gap 407 is formed between them. The middle section of the intermediate tube 401 has an annular opening 405. The rubber ring 403 is annular and has a filling chamber inside. The longitudinal section structure of the water cavity 408 and the rubber ring 403 is H-shaped, and the water injection cavity is also H-shaped. The width of the opening 405 is smaller than the width of the annular notch of the rubber ring 403. The end of the gap 407 away from the water storage bladder 406 is provided with several annularly distributed water outlet holes 409. The inner side of the rubber ring 403 passes through the opening 405 and is embedded in the gap. The water injection cavity 408 is located in the gap and has an annular notch that communicates with the gap on the side near the water outlet hole 409. The outer side of the rubber ring 403 is connected to the water storage bladder 406 through a hose. Several rubber flanges 8 are provided on the inner side of the intermediate tube 404.

[0055] When the endoscopic image is blurry, saline solution can be injected into the injection chamber 408 of the rubber ring 403 through the reservoir 406. After the injection chamber 408 is filled with saline solution, the saline solution flows into the gap 407 between the intermediate tube 1 401 and the intermediate tube 2 404 along the periphery of the opening 405. Then, the saline solution flows out from the outlet 409 to clean the endoscope. This ensures that the endoscope can be cleaned evenly at various angles. The rubber flange 1 8 ensures that the friction of the rubber flange 1 8 on the inner side of the intermediate tube 2 404 can prevent the endoscope from sliding or wobbling after it is adjusted to the optimal position, thus improving the safety and efficiency of the operation. The structure of the rubber ring ensures a tight seal and also ensures normal delivery of saline solution while the intermediate tube assembly rotates.

[0056] The side tube assembly includes a side tube 301 and a spherical rotor 302 rotatably mounted within a support hole 24. The spherical rotor 302 is sleeved and fixedly mounted on the outer middle section of the side tube 301. Several rubber flanges 9 are provided on the inner side of one of the side tubes 301. Because the spherical rotor 402 forms a movable fit with the rubber ring 403, and because the spherical tube 1 and spherical tube 2 form a movable fit, the intermediate tube 1 401 and intermediate tube 2 404 can rotate relative to each other. The tube 301 and the spherical rotor 302 can rotate relative to each other. If a cannula is inserted into the side tube 301 and the spherical rotor 302, the cannula can be bent at will. The rubber flange 8 and the rubber flange 9 are mainly used to increase the friction between the cannula and the tube wall. The friction between the rubber flange 8 on the inner side of the middle tube 404 and the rubber flange 9 on the inner side of the side tube 301 can ensure that the endoscope will not slip after being adjusted to the optimal position, thus improving the operability and comfort of the endoscope.

[0057] The support plate 22 is integrally formed from two symmetrically arranged support plates 25. Each support plate 25 is provided with several hemispherical through holes 26. The diameter of one end of the through hole 26 is larger than the diameter of the other end of the plate. The through holes 26 of the two support plates 25 are connected one-to-one and the larger ends of the two plates are fitted together. This ensures that the spherical rotor 402 and the spherical rotor 302 will not fall out of the corresponding support hole 23 or support hole 24 while rotating in the corresponding support hole 23 or support hole 24, thus avoiding damage to the endoscope.

[0058] Working principle: The small motor 10 drives the bevel gear 7 12 to rotate via the output shaft transmission shaft 11. The bevel gear 7 12 drives the meshing bevel gear 4 701 to rotate. The bevel gear 4 701 drives the fixed transmission rod 2 702 to rotate. The driven transmission rod 2 702 drives the fixed bevel gear 5 703 to rotate. The rotation of bevel gear 5 703 drives the rotation of bevel gear 6 704. Then, bevel gear 6 704 drives the meshing bevel gear 5 703 to rotate. The two bevel gears 5 703 rotate in opposite directions. Similarly, the transmission component 1 6 and the adjustment component 1 7 have similar structures, so the adjustment component... Power is transmitted from component 17 to transmission component 6. The internal movement of transmission component 6 is identical. Therefore, the external threaded cylinders 19 within adjustment components 17, 27, and 38 rotate in the same direction. Through threaded transmission, the external threaded cylinders 19 can control the three cylinders 501 to move synchronously outwards or inwards, facilitating the finding of a stable support point for surgical operations. This prevents image swaying caused by the scope's movement, improving surgical efficiency and reducing safety hazards. The small motor 214 rotates the threaded rod 15 via its output shaft. The threaded rod 15, through threaded transmission, controls the support plate body 201 to move outwards or inwards. The support plate 201 moves along the bone edge. Because the three small motors 14 are independently configured, the three control supports 201 can be independently controlled, allowing for micro-adjustments based on the surgical situation. When the endoscopic image is blurry, the outlet of the reservoir 406 is connected to the rubber ring 403 via a hose, and the inlet of the reservoir 406 is connected to the outlet of the micro-pump via a hose. When cleaning is required, the micro-pump injects saline solution into the injection chamber 408 of the rubber ring 403. Once the injection chamber 408 is full, the saline solution flows around the opening 405 into the central tube 401 and the central tube 402. Within the gap 407 between the two tubes 404, saline solution flows out from the outlet 409 to clean the endoscope. When the gap 407 of the intermediate tube is blocked, saline solution can be injected into the gap 407 of the intermediate tube by squeezing the reservoir 406. When squeezing, the instantaneous water pressure increases and clears the blockage in the gap 407 of the intermediate tube, ensuring uniform cleaning of the endoscope at various angles. The rubber flange 8 ensures that the friction of the rubber flange 8 on the inner side of the intermediate tube 404 ensures that the endoscope will not slide or swing freely after being adjusted to the optimal position, thus improving the safety and efficiency of the surgery.

[0059] The friction between the rubber flange 8 on the inner side of the intermediate tube 2 404 and the rubber flange 9 on the inner side of the side tube 301 ensures that the endoscope will not slip after being adjusted to the optimal position, thus improving the comfort of endoscope operation.

[0060] Example 2:

[0061] Example 2 adds the following structure to Example 1:

[0062] like Figures 1-15 As shown, the support plate assembly 2 includes a support plate body 201 and a fixed cylinder 202. The inner wall of the fixed cylinder 202 has evenly distributed sliding openings. The fixed cylinder 202 is sleeved on the outer wall of the cylinder 501. The guide strip 502 is slidably installed on the inner wall of the sliding openings. The support plate body 201 is fixed to the outer wall of the fixed cylinder 202 facing away from the cylinder 501. The support plate body 201 has threaded holes facing the outer wall of the fixed cylinder 202. Three small motors 14 are fixed to the annular plate 13. The output shaft of each small motor 14 is fixed with a threaded rod 15. The threaded rod 15 is threadedly connected to the inner wall of the threaded hole. The small motors 14 rotate the threaded rod 15 through their output shafts. The threaded rod 15 is driven by a threaded transmission. The support plate body 201 can be moved outward or inward. Since the three small motors 214 are independently set, the three support plate bodies 201 can be controlled independently, so that they can be finely adjusted according to the surgical situation. The support plate body 201 can also be supported on the skull to move the endoscope to the surgical position and ensure the smooth progress of the operation. In the case of irregular surgical wound, the endoscope can be moved to the optimal position by adjusting the position of the support plate body 201. The side of the support plate body 201 away from the outer shell is an arc structure and the middle section of one side of the arc is made of rubber, which can ensure that the support plate body 201 presses against the skull and engages with the edge of the bone. At this time, the rubber concave side of the arc of the support plate body 201 is C-shaped.

[0063] Working principle: The small motor 10 drives the bevel gear 7 12 to rotate through the output shaft transmission shaft 11. The bevel gear 7 12 drives the meshing bevel gear 4 701 to rotate. The bevel gear 4 701 drives the fixed transmission rod 2 702 to rotate. The driven transmission rod 2 702 drives the fixed bevel gear 5 703 to rotate. The rotation of bevel gear 5 703 drives the rotation of bevel gear 6 704. Then, bevel gear 6 704 drives the meshing bevel gear 5 703 to rotate. The two bevel gears 5 703 rotate in opposite directions. Similarly, the transmission component 1 6 and the adjustment component 1 7 have similar structures, so the adjustment component 1 7 transmits power to the transmission component 1 6. The internal movement of the transmission component 1 6 is the same. Therefore, the external threaded cylinder 19 in the adjustment component 1 7, adjustment component 2 17 and adjustment component 3 18 rotates in the same direction. The external threaded cylinder 19, through the threaded transmission, can control the three cylinders 501 to move outward synchronously, thus ensuring the fixed support point; the small motor 2 14. The output shaft rotates the threaded rod 15, which, through threaded transmission, controls the support plate body 201 to move outward or inward. The support plate body 201 rests against the bone edge. Since the three small motors 14 are independently set, the three control support plates 201 can be independently controlled, allowing for micro-adjustment according to the surgical situation. When the endoscopic image is blurry, saline can be injected into the water injection chamber 408 of the rubber ring 403 through the water reservoir 406. After the saline fills the water injection chamber 408, the saline flows into the gap 407 between the intermediate tube 1 401 and the intermediate tube 2 404 along the periphery of the opening 405. Then, the saline flows out from the water outlet 409 to clean the endoscope, ensuring uniform cleaning of the endoscope at various angles. The rubber flange 8 ensures that the friction of the rubber flange 8 on the inner side of the intermediate tube 2 404 prevents the endoscope from rotating or shifting randomly after being adjusted to the optimal position, thus reducing the difficulty of the surgery to a certain extent.

[0064] The friction between the rubber flange 8 on the inner side of the intermediate tube 2 404 and the rubber flange 9 on the inner side of the side tube 301 ensures that the endoscope will not rotate or move around randomly after being adjusted to the optimal position, thus reducing the difficulty of the surgery to a certain extent.
