Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an intelligent integrated coagulation and cutting device for laparoscopic liver resection. Background Technology
[0002] The intelligent coagulation and cutting knife for laparoscopic liver resection does not refer to a specific surgical knife, but rather a surgical device system that integrates intelligent energy technology. Its core design goal is to safely and efficiently complete the two key operations of liver tissue cutting and separation and hemostasis and coagulation in a minimally invasive laparoscopic environment.
[0003] Since most of the intelligent coagulation cutting knives used in laparoscopic liver resections in clinical practice are based on the principle of ultrasound, they are most directly referred to as ultrasonic knives. The working principle is that the vibrating blade can break the protein structure of the tissue under low pressure to achieve precise cutting. The heat generated by the vibration denatures and melts the protein in the tissue, thereby achieving simultaneous hemostasis of ruptured small blood vessels and bile ducts.
[0004] Currently, the intelligent coagulation cutting knife for laparoscopic liver resection on the market uses multiple bolts for positioning and connection of the tube body, and different models of cutting knives may need to be replaced during surgery. However, the existing intelligent coagulation cutting knife for laparoscopic liver resection lacks a component for quick replacement, which prevents the intelligent coagulation cutting knife for laparoscopic liver resection from performing the function of quick alignment insertion and alignment protection. Therefore, a device is needed to improve this function. Summary of the Invention

[0010] Specifically, the guiding device includes an operating handle, a central iron frame, a guide crossbar, a supporting round cover, an integrated socket, a contact piece, a U-shaped limiting rod, a second return spring, a hexagonal rod, and a supporting recess. The supporting round cover is fixedly installed at the top front end of the operating handle. The integrated socket is fixedly installed at the center front end of the supporting round cover. The guide crossbar is fixedly installed at the top and bottom rear ends of the supporting round cover. The central iron frame is fixedly installed at the center top end of the guide crossbar. The supporting recess is symmetrically fixedly installed inside the supporting round cover. The U-shaped limiting rod is slidably inserted into the supporting round cover near the supporting recess. The second return spring is fixedly installed between the supporting recess and the U-shaped limiting rod. The hexagonal rod slides through the supporting recess and connects to the U-shaped limiting rod, and the hexagonal rod is located at the center of the inner ring of the second return spring.

[0015] The beneficial effects of this invention are:
[0016] First, this invention allows the guide sleeve to slidably insert into the groove of the outer ring of the integrated socket, thus supporting the placement of the rod. Simultaneously, the rotation of the plastic ring causes the limiting block to press against the contact arc plate, moving downwards and allowing the positioning rod to insert into the guide sleeve, thus restricting the rod. Furthermore, the rotation of the rotating collar causes the rear contact block to rotate and engage with the U-shaped limiting rod, allowing the U-shaped limiting rod to insert into the square groove, thus restricting the rotating collar and preventing it from rotating again. The first return spring allows the positioning rod to be pulled out from the guide sleeve when the contact arc plate is not under pressure, facilitating the release of the rod and enabling quick assembly and docking of the rod with the integrated socket.
[0017] Second, the present invention allows the guide key to be slidably inserted into the front end of the guide crossbar, enabling the protective cover to move in a straight line. By merging two protective covers over the outer ring of the supporting round cover, the supporting round cover and the integrated socket can be protected. At the same time, the protective cover can be fixed by magnetic adsorption and adhesion to the central iron frame. Furthermore, by extending the sleeve over the outer ring of the rod, the root of the rod can be protected, preventing bending of the root area of the rod. This completes the work of covering and protecting the supporting round cover. Attached Figure Description

[0036] like Figure 7 and Figure 8 The guiding device 14 includes an operating handle 27, a central iron frame 28, a guide crossbeam 29, a supporting round cover 30, an integrated socket 31, a contact piece 32, a U-shaped limiting rod 33, a second return spring 34, a hexagonal rod 35, and a supporting recess 36. The supporting round cover 30 is fixedly installed on the top front end of the operating handle 27, the integrated socket 31 is fixedly installed on the center front end of the supporting round cover 30, the guide crossbeam 29 is fixedly installed on the top and bottom rear ends of the supporting round cover 30, the central iron frame 28 is fixedly installed on the center top end of the guide crossbeam 29, and the supporting recess 36 is symmetrically fixed. The U-shaped limiting rod 33 is slidably inserted into the support round cover 30 near the support recess 36.

The hexagonal rod 35 slides through the support recess 36 and connects with the U-shaped limiting rod 33, and the hexagonal rod 35 is located at the center of the inner ring of the second return spring 34. The contact piece 32 is fixedly installed at the end of the U-shaped limiting rod 33 away from the support recess 36. The contact piece 32 can be supported to move in a straight line by sliding the hexagonal rod 35 inside the support recess 36.
[0037] The power plug 5 is slidably inserted into the front end of the integrated socket 31. The supporting outer ring 24 is fixedly installed on the front end of the supporting round cover 30. The rotating collar 17 is rotatably sleeved on the outer ring of the supporting round cover 30. The guide key 8 is slidably inserted into the front end of the guide crossbar 29. The guide sleeve 4 is slidably inserted into the outer ring of the integrated socket 31. A round hole is opened at the bottom of the inner end of the guide sleeve 4. The bottom ends of the limiting pressure block 19 and the bottom ends of the rear contact block 15 are all inclined at 45°. The top end of the contact arc plate 25 is arc-shaped. The U-shaped limiting rod 33 is away from the contact piece 32. The top of the support cover 30 is arc-shaped, and the outer ring of the support cover 30 has a rotating groove. The outer ring of the integrated socket 31 has symmetrical grooves, and the grooves are distributed in a ring. The outer ring of the support cover 30 has a socket that matches the U-shaped limiting rod 33. The front end of the guide crossbar 29 has a slot. The magnetic plate 9 is horizontally aligned with the central iron frame 28. The limiting pressure block 19 is aligned with the contact arc plate 25. The rear contact block 15 is aligned with the top of the end of the U-shaped limiting rod 33 away from the contact plate 32. The interior of the protective cover 10 is hollow, and the extension sleeve 11 is interconnected with the protective cover 10.
[0038] The working principle of Embodiment 1 is as follows: During use, the power plug 5 is inserted into the integrated socket 31, allowing the operating handle 27 to connect with the rod body 6, thus enabling operation of the rod body 6 and allowing it to perform cutting work. When it is necessary to replace a different rod body 6, the protective cover 10 can be moved away from the central iron frame 28 until the guide slide key 8 is pulled out from the inside of the guide crossbar 29. Then, the two contact pieces 32 are pressed towards the end close to the support round cover 30, so that the U-shaped limiting rod 33 can be moved out from the inside of the square groove 18, releasing the rotating collar 17. At this time, the rotating collar 17 can be rotated until the limiting pressure block 19 is misaligned with the contact arc plate 25. The elasticity of the first reset spring 21 will drive the positioning rod 23 to move upward and reset. This allows the positioning rod 23 to be moved out of the guide sleeve 4, releasing the guide sleeve 4. At this point, the user can pull the rod body 6 away from the operating handle 27 until the power plug 5 is pulled out of the integrated socket 31. The rod body 6 can then be removed. Subsequently, the corresponding model of the rod body 6 can be moved to the front end of the integrated socket 31 until the power plug 5 is inserted into the integrated socket 31. The guide sleeve 4 slides into the groove on the outer ring of the integrated socket 31, allowing the rod body 6 to be aligned with the integrated socket 31 in a straight line. Then, when the guide sleeve 4 moves to its limit position in the groove inside the integrated socket 31, the round hole inside the guide sleeve 4 can be vertically aligned with the positioning rod 23. At this point, the rotating collar 17 can be rotated in the opposite direction to drive the limiting pressure. When block 19 rotates to contact the contact arc plate 25, the bottom ends of the limiting block 19 are inclined at 45°, and the top of the contact arc plate 25 is arc-shaped, which improves the smoothness of contact between the limiting block 19 and the contact arc plate 25. When the limiting block 19 is fully rotated to be perpendicularly aligned with the top of the contact arc plate 25, the contact arc plate 25 can be pressed downward by the limiting block 19 to the limit position, so that the positioning rod 23 can be inserted into the round hole inside the guide sleeve 4, which can restrict and fix the guide sleeve 4. At the same time, the rotating collar 17 can also drive the rear contact block 15 to rotate at the same time. When the limiting block 19 is rotated to be perpendicularly aligned with the contact arc plate 25, the square groove 18 inside the rear contact block 15 can interact with the U-shaped groove. The end of the U-shaped limiting rod 33 furthest from the contact piece 32 is aligned. The elasticity of the second return spring 34 causes the U-shaped limiting rod 33 to move upwards and reset, allowing it to insert into the square groove 18. The bottom ends of the rear contact block 15 are inclined at 45°, and the top of the U-shaped limiting rod 33 furthest from the contact piece 32 is rounded, improving the smoothness of contact between the rear contact block 15 and the U-shaped limiting rod 33. Subsequently, when the end of the U-shaped limiting rod 33 furthest from the contact piece 32 is inserted into the square groove 18, the rear contact block 15 is fixed, preventing the rotating collar 17 from rotating again, thus locking the rotating collar 17. Afterwards, the guide slide key 8 can be moved and inserted into the slot inside the front end of the guide crossbar 29.This allows the protective cover 10 to move along a straight line at the front end of the guide crossbar 29 until the magnetic plate 9 moves to adhere to the central iron frame 28. The protective cover 10 then covers the outer ring of the supporting round cover 30 for protection, completing the quick replacement of the rod body 6. In use, the device can be inserted into the integrated socket 31 via the guide sleeve 4, allowing the power plug 5 to quickly connect with the integrated socket 31. Simultaneously, rotating the collar 17 causes the limiting block 19 to press against the arc plate 25 downwards, thus confining the guide sleeve 4 inside the integrated socket 31. Furthermore, as the collar 17 rotates, it engages with the U-shaped limiting rod 33 via the square groove 18, locking the collar 17 in place. Simultaneously, the protective cover 10 slides onto the outer ring of the supporting round cover 30, protecting it from external splashes and preventing direct contact. This completes the operation.
[0039] Example 2
[0040] Based on Example 1, such as Figure 9 As shown, the rod body 6 also includes a scraper plate 37 and an auxiliary positioning sleeve 38. The scraper plate 37 is slidably sleeved on the outer ring of the rod body 6, and the auxiliary positioning sleeve 38 is fixedly installed at the center of the side end of the scraper plate 37.
[0041] In this embodiment, the scraper plate 37 is slidably sleeved on the outer ring of the rod body 6. When impurities are attached to the outer ring of the rod body 6, the scraper plate 37 can be pushed towards the front end, so that the scraper plate 37 can remove the impurities attached to the outer ring of the rod body 6. At the same time, the inner wall of the auxiliary positioning sleeve 38 is provided with a sleeve hole that fits with the outer ring of the extension sleeve 11, so that when the scraper plate 37 moves along the outer ring of the rod body 6 to the rear end to the limit position, it can be slidably sleeved on the outer ring of the two extension sleeves 11, so that the two extension sleeves 11 can be restricted and fixed, thus completing the work.
