Description

Technical Field

[0001] This invention relates to the field of endoscopic equipment technology, and more specifically to an electrically powered foot-operated endoscopic surgical positioning system. Background Technology

[0002] Endoscopic surgery, with its advantages of minimal trauma, less pain, and faster recovery, has become the mainstream minimally invasive surgical method in general surgery, urology and other fields. Its core is to use an endoscope to enter the abdominal cavity to collect real-time images and provide the surgeon with a surgical field of vision. The clamping and fixation of the endoscope is a key part of the surgical process, which directly affects the stability of the surgical field of vision and the accuracy of operation. If the clamping and fixation is not done properly, it can easily lead to the deviation and blurring of the surgical field of vision, increasing the risk of surgical errors.

[0003] Currently, the most common method for holding and fixing endoscopes in clinical practice is manual clamping. Manual clamping is usually operated by an assistant surgeon, who must hold the endoscope throughout the entire procedure to assist the surgeon. During this process, the surgeon needs to constantly communicate with the assistant surgeon to clarify the required positional adjustments of the endoscope. This not only distracts the surgeon and affects the continuity of the operation but may also lead to inaccurate endoscope positioning due to communication misunderstandings. At the same time, manual clamping significantly increases the workload of the assistant surgeon, and prolonged operation can easily lead to fatigue, causing the endoscope to shift position and affecting the stability of the surgical field. Furthermore, hand-held operation is susceptible to tremors caused by the surgeon's movements, further reducing the clarity of the field of vision. To address these issues, we have proposed an electrically powered foot-operated endoscopic surgical positioning system. Summary of the Invention

[0004] The present invention aims to provide an electrically powered foot-operated endoscopic surgical positioning system to solve the problem that the surgeon needs to constantly communicate with the assistant surgeon to clarify the position adjustment requirements of the endoscope, which not only distracts the surgeon's attention but also affects the continuity of the operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electric foot-operated endoscopic surgical positioning system, comprising a rotating assembly, a tilting assembly, and two clamping assemblies. The rotating assembly includes a mounting shell, a rotating sleeve, and a first driving member. The mounting shell has a rotating groove coaxially extending through it, and the rotating sleeve is coaxially rotatably disposed within the rotating groove. A rotating cavity is formed in the inner wall of the rotating groove. The first driving member is disposed within the rotating cavity and can drive the rotating sleeve to rotate. The tilting assembly is disposed within the rotating sleeve and includes a second driving member and a tilting sleeve. A tilting shaft is symmetrically disposed on the outer wall of the tilting sleeve, and both ends of the tilting shaft are rotatably connected to the inner wall of the rotating sleeve. The driving component is located between the rotating sleeves, and the second driving component can drive the tilting sleeve to rotate. Two clamping components are symmetrically arranged on the upper end of the rotating sleeve. The clamping components include a mounting post, a rotating block, an arc block, an arc guide rail, and a circular arc block. The mounting post is located on the upper end of the rotating sleeve, and a rotating groove is opened on the upper end of the mounting post. The rotating block is located in the rotating groove. The arc block is located on the upper end of the rotating block. The arc guide rail is located at one end of the arc block. A matching slider is provided on the outer wall of the arc guide rail. The circular arc block is located at the end of the slider away from the arc guide rail. The opposite ends of the circular arc blocks of the two clamping components are provided with locking components. When the two circular arc blocks abut against each other, they can form a closed ring and clamp the endoscope.

[0006] The beneficial effects of this solution are as follows: the endoscope can be adjusted through the coordinated operation of the rotating component and the tilting component. The rotating component drives the rotating sleeve to rotate coaxially in the rotating groove through the first driving component, realizing the 360° rotation of the endoscope. The tilting component drives the tilting sleeve to rotate around the tilting axis through the second driving component, which can flexibly adjust the tilt angle of the endoscope. The cooperation between the rotating component and the tilting component can quickly adapt to the field of view requirements of different surgeries, greatly improving the flexibility and accuracy of endoscope adjustment. The two symmetrically arranged clamping components can achieve stable clamping of the endoscope. The cooperation between the arc-shaped guide rail and the slider allows the arc block to move flexibly, so that the two arc blocks can be joined to form a closed ring that can adaptively adjust with the tilt of the endoscope. Moreover, the locking component at the opposite end of the arc block can lock the clamping state, avoiding the situation of loose clamping or over-clamping and damage to the instrument.

[0007] Preferably, as an improvement, each arc block is provided with a drive groove, a rotating roller is provided in the drive groove, a drive motor is provided in the drive groove, the output end of the drive motor is fixedly connected to one end of the rotating roller, and the symmetrically arranged rotating rollers can abut against the outer wall of the endoscope.

[0008] The beneficial effects are as follows: the drive motor in the drive slot can drive the rotating rollers to rotate. The symmetrically arranged rotating rollers abut against the outer wall of the endoscope, which can drive the endoscope to achieve axial feed or fine adjustment without the surgeon having to manually push the endoscope, further improving the ease of operation.

[0009] Preferably, as an improvement, the locking component includes a buckle and a locking pin. A first inclined surface has a first locking groove, and the buckle is rotatably disposed in the first locking groove. The buckle also has a locking groove. A second inclined surface has a second locking groove, and the second locking groove is connected to an unlocking hole. The locking pin is slidably disposed in the unlocking hole. The outer wall of the locking pin has a locking block that can engage with the locking groove. The outer wall of the locking pin has an unlocking groove, and the buckle can slide in the unlocking groove. One end of the locking pin located in the locking groove is provided with a return spring on the inner wall of the locking groove.

[0010] The beneficial effects are as follows: When the first and second inclined surfaces of the two arc blocks are aligned, and the buckle is inserted into the second locking groove, the end of the buckle contacts the locking block and rotates along the inclined surface of the locking block until the locking groove of the buckle engages with the locking block, thereby locking the two arc blocks. This effectively prevents loosening of the clamping caused by collisions during the operation and improves the stability of the endoscope clamping. When unlocking, by pressing the locking pin, the locking pin moves into the unlocking hole, and during this process, the return spring is compressed until the locking groove of the buckle moves into the unlocking groove, allowing the buckle to quickly exit the second locking groove from the unlocking groove. This allows the two arc blocks to be unlocked quickly, thereby completing the disassembly of the endoscope and improving the efficiency of the surgical operation.

[0011] Preferably, as an improvement, it also includes a guide tube, which is disposed inside the inclined sleeve. The upper end of the inclined sleeve is symmetrically provided with snap-fit ​​grooves. A pop-out component is provided in the snap-fit ​​groove. The pop-out component includes an ejector block and a spring. The ejector block is slidably disposed in the snap-fit ​​groove. The inner wall of the snap-fit ​​groove is symmetrically provided with guide grooves. The ejector block is slidably disposed between the guide grooves. The spring is disposed between the ejector block and the snap-fit ​​groove. The outer wall of the guide tube is symmetrically provided with limiting blocks that match the snap-fit ​​groove. Each arc block has a pressing block at its lower end. The pressing block can press the limiting block into the snap-fit ​​groove.

[0012] The beneficial effects are as follows: the guide groove on the inner wall of the snap-fit ​​groove can guide the sliding of the ejector block, ensuring smooth movement of the ejector block, avoiding jamming, and improving the operational stability of the ejector; when the two arc blocks clamp the endoscope, the pressure block at the lower end of each arc block simultaneously presses the limiting block into the snap-fit ​​groove, realizing the quick installation of the guide tube and improving the ease of operation; when unlocking, simply loosen the locking structure of the two arc blocks, and the spring pushes the ejector block to push the limiting block out of the snap-fit ​​groove, allowing the doctor to quickly remove the guide tube, realizing convenient disassembly of the guide tube.

[0013] Preferably, as an improvement, the outer wall of the guide tube is provided with several auxiliary rollers, which can abut against the endoscope, and the inclined sleeve is symmetrically provided with a take-out groove, and the limiting block can slide out of the inclined sleeve from the take-out groove.

[0014] The beneficial effects are as follows: the auxiliary roller can contact the endoscope, thereby guiding the endoscope. Through the rolling contact of the auxiliary roller, the sliding friction between the endoscope and the inner wall of the guide tube is reduced, and the endoscope is prevented from shaking in the guide tube, ensuring the smoothness and stability of the endoscope adjustment.

[0015] Preferably, as an improvement, the first driving component includes a first motor, a first gear, a mounting base, and a gear disc. The mounting base is located on the inner wall of the rotating cavity, the first motor is located on the upper end of the mounting base, and the output end of the first motor extends through the mounting base. The first gear is located on the lower end of the output end of the first motor, and the gear disc is located on the outer wall of the rotating sleeve, and the first gear meshes with the gear disc.

[0016] Preferably, as an improvement, the second driving component includes a second motor, a second gear, and a half-tooth. The second motor is located on the outer wall of the rotating sleeve, and the output end of the second motor rotates through into the rotating sleeve. The second gear is located at the output end of the second motor, and the half-tooth is located on the outer wall of the inclined rotating shaft, and the half-tooth meshes with the second gear.

[0019] Example 1 Example 1 is basically as shown in the appendix. Figures 1-9 As shown, Figure 1 The electrically operated foot-controlled endoscope 46 surgical positioning system shown includes a fixed support 1, a rotating assembly, a tilting assembly, and two clamping assemblies. The fixed support 1 consists of multiple transmission pairs; for details, please refer to Chinese Patent CN215606123U (A puncture needle fixing device and a treatment device for minimally invasive surgery), which will not be elaborated upon here. The rotating assembly includes a mounting shell 2, a rotating sleeve 5, and a first driving component. The mounting shell 2 is fixedly installed on the right end of the fixed support 1. Figure 2 The mounting shell 2 shown has a rotating groove 3 coaxially extending through its middle. A bearing 4 is fixedly installed on the inner wall of the upper end of the rotating groove 3. A rotating sleeve 5 is coaxially and rotatably fixedly installed on the inner wall of the bearing 4. A rotating cavity 6 is coaxially opened on the inner wall of the rotating groove 3. A first driving component is located in the rotating cavity 6 and can drive the rotating sleeve 5 to rotate. The first driving component includes a first motor 7, a first gear 9, a mounting base 8, and a gear disk 10. The mounting base 8 is fixedly installed on the upper wall of the rotating cavity 6 and is L-shaped. The first motor 7 is fixedly installed on the upper end of the mounting base 8, and the output end of the first motor 7 rotates through the mounting base 8. The first gear 9 is fixedly installed on the lower end of the output end of the first motor 7. The gear disk 10 is fixedly installed on the outer wall of the rotating sleeve 5, and the first gear 9 meshes with the gear disk 10.

[0020] The tilting assembly is located inside the rotating sleeve 5. The tilting assembly includes a second driving member and a tilting sleeve 12, as shown below. Figure 3 The inclined sleeve 12 shown is symmetrically fixedly mounted with inclined rotating shafts 11 on its outer wall. Both ends of the inclined rotating shafts 11 are rotatably connected to the inner wall of the rotating sleeve 5, as shown below. Figure 4A rectangular groove 13 is provided in the middle of the rotating sleeve 5 along the rotation direction of the inclined sleeve 12. The rectangular groove 13 can increase the rotation angle of the inclined sleeve 12, so that the surgeon can obtain a better field of vision. The second driving component is located between the rotating sleeves 5. The second driving component includes a second motor 14, a second gear 15, and a half gear 16. The second motor 14 is fixedly installed on the outer wall of the rotating sleeve 5, and the output end of the second motor 14 rotates through into the rotating sleeve 5. Figure 3 The second gear 15 shown is fixedly installed at the output end of the second motor 14, and the half gear 16 is fixedly installed on the outer wall of the inclined shaft 11 located on the right side, and the half gear 16 meshes with the second gear 15.

[0021] like Figure 5 The two clamping assemblies shown are symmetrically arranged on the upper end of the rotating sleeve 5. Each clamping assembly includes a mounting post 17, a rotating block 47, an arc-shaped block 19, an arc-shaped guide rail 20, and a circular arc block 22. The mounting post 17 is fixedly installed on the upper end of the rotating sleeve 5. A rotating groove 18 is opened at the upper end of the mounting post 17. The rotating block 47 is rotatably installed within the rotating groove 18. Specifically, a rotating rod is fixedly installed within the rotating groove 18. A through hole is opened at the lower end of the rotating block 47, through which the rotating block 47 is rotatably installed on the outer wall of the rotating rod. The arc-shaped block 19 is fixedly installed on the upper end of the rotating block 47. The arc-shaped guide rail 20 is fixedly pressed against the opposite ends of the two arc-shaped blocks 19. A matching slider 21 is slidably installed on the outer wall of the arc-shaped guide rail 20. The circular arc block 22 is fixedly installed at the opposite ends of the two sliders 21. Figure 6 The left-side arc block 22 has a first inclined surface 23 at both ends, and the right-side arc block 22 has a second inclined surface 24 parallel to the first inclined surface 23 at both ends. The first inclined surface 23 and the second inclined surface 24 can fit together, forming a closed loop when the ends of the two arc blocks 22 abut. The fitting first and second inclined surfaces 23 and 24 ensure a tighter fit when the two arc blocks 22 are joined, preventing radial wobbling of the endoscope 46 during clamping and further improving clamping stability. Simultaneously, the first and second inclined surfaces 23 and 24 guide the two arc blocks 22 to quickly align, facilitating rapid clamping and positioning of the endoscope 46 and improving operational convenience. Figure 7 Each of the arc blocks 22 shown has a drive groove in its center. A rotating roller 25 is rotatably installed in the drive groove. A drive motor (not shown in the figure) is fixedly installed in the drive groove. The output end of the drive motor is fixedly connected to one end of the rotating roller 25. The symmetrically arranged rotating rollers 25 can abut against the outer wall of the endoscope 46. The outer wall of the rotating roller 25 is covered with a sponge layer with a thickness of 2-3 mm. The outer wall of the sponge layer is covered with silicone with a thickness of 1-2 mm. In this embodiment, the thickness of the sponge layer is 2 mm and the thickness of the silicone is 1 mm.

[0022] Both of the arc-shaped blocks 22 of the two clamping components have locking elements at opposite ends. The locking elements include a snap-fit ​​27 and a locking pin 32, such as... Figure 8 The first inclined surface 23 shown has a first locking groove 26, and the buckle 27 is rotatably installed in the first locking groove 26. The end of the buckle 27 has a guide surface 28, and the lower end of the buckle 27 has a locking groove 29. Figure 7 The second inclined surface 24 shown has a second locking groove 30. The first locking groove 26 is opposite to the second locking groove 30, and both the first locking groove 26 and the second locking groove 30 are rectangular. The outer wall of the arc block 22 has an unlocking hole 31 that communicates with the second locking groove 30. The cross-section of the unlocking hole 31 is circular. The locking pin 32 is slidably installed in the unlocking hole 31. The outer wall of the locking pin 32 has a locking block 33 that can engage with the locking groove 29. The cross-section of the locking block 33 is a right triangle. The outer wall of the locking pin 32 has an unlocking groove 34. The width of the unlocking groove 34 is greater than the width of the buckle 27, so that the buckle 27 can slide in the unlocking groove 34. One end of the locking pin 32 located in the locking groove 29 is fixedly installed between the locking pin 32 and the inner wall of the locking groove 29. When the return spring 35 is in its natural state, the other end of the locking pin 32 is located outside the unlocking hole 31, and the locking block 33 is located in the second locking groove 30.

[0023] like Figure 2 The diagram also includes a guide tube 36, which is snapped into the inclined sleeve 12, as shown. Figure 9 The inclined sleeve 12 shown has symmetrically formed snap-fit ​​grooves 37 on its upper end. A pop-out component is provided within the snap-fit ​​groove 37, including an ejector block 39 and a spring 40. Guide grooves 38 are symmetrically formed on the inner wall of the snap-fit ​​groove 37. The ejector block 39 is slidably installed within the snap-fit ​​groove 37. The spring 40 is fixedly installed between the lower end of the ejector block 39 and the snap-fit ​​groove 37. A receiving groove 41 is formed at the lower end of the snap-fit ​​groove 37, allowing the compressed spring 40 to be completely contained within the receiving groove 41. Figure 2 The guide tube 36 shown has symmetrically fixed limiting blocks 42 that match the snap-fit ​​groove 37 on its outer wall, such as... Figure 5 Each of the arc blocks 22 shown has a pressure block 43 fixedly installed at its lower end, which can press the limiting block 42 into the snap-fit ​​groove 37.

[0024] like Figure 2 The guide tube 36 shown is rotatably mounted with several auxiliary rollers 44. In this embodiment, four auxiliary rollers 44 are provided, and each auxiliary roller 44 can abut against the outer wall of the endoscope 46. Figure 9 The inclined sleeve 12 shown is symmetrically provided with a take-out groove 45. The limiting block 42 can slide out of the inclined sleeve 12 from the take-out groove 45, and a 90° angle is formed between the adjacent take-out groove 45 and the snap-fit ​​groove 37.

[0025] The specific implementation process is as follows: In use, the doctor places the guide tube 36 at the lower end of the inclined sleeve 12 and aligns the limiting blocks 42 on both sides of the guide tube 36 with the take-out groove 45 of the inclined sleeve 12. Then, the upper end of the guide tube 36 is passed through the inclined sleeve 12 from bottom to top. The guide tube 36 is then rotated 90° so that the limiting blocks 42 are positioned at the upper end of the locking groove 37. The doctor then inserts the endoscope 46 to be used into the guide tube 36 from top to bottom until the lower end of the endoscope 46 passes through the auxiliary roller 44 and exits the guide tube 36. At this point, the auxiliary roller 44 abuts against the outer wall of the endoscope 46. Finally, the doctor rotates the two circular... The arc blocks 22 are engaged until they form a closed ring. At this point, the rotating roller 25 abuts against the outer wall of the endoscope 46, and the rotating roller 25 is driven by the drive motor to rotate, thereby controlling the lifting and lowering of the endoscope 46. The rotating arc blocks 22 drive the pressure block 43 to press down the limiting block 42 and press the limiting block 42 into the locking groove 37, so that the guide tube 36 does not rotate relative to the inclined sleeve 12. When unlocking, simply press the locking pin 32 to move the locking pin 32 into the unlocking hole 31. During this process, the return spring 35 is compressed until the locking groove 29 of the buckle 27 moves to the locking position. Within the unlocking slot 34, the latch 27 quickly exits the second locking slot 30, allowing the two arc blocks 22 to unlock rapidly. The separated arc blocks 22 drive the pressure block 43 to rotate, causing the limiting block 42 to exit the locking slot 37 under the action of the ejector block 39. This causes the guide tube 36 to move upward, which in turn moves the endoscope 46 inside the guide tube 36 upward. Finally, the endoscope 46 is slowly pulled out of the guide tube 36, forming a certain angle between the endoscope 46 and the abdominal wall puncture hole, reducing the direct pressure and scraping of the lens on the blood vessels at the edge of the puncture hole, and reducing the pull-out time. In cases of ruptured abdominal wall blood vessels or active bleeding, the intestines and omentum may easily adhere to the trocar opening before the endoscope is removed. Directly removing the endoscope 46 may cause it to be pulled out of the body. Furthermore, the field of view of the endoscope 46 will be slightly expanded after it is moved upward, allowing the surgeon to quickly scan the surgical area to confirm that there is no active bleeding, no missed lesions, and no instrument residue. At the same time, when the pneumoperitoneum pressure is released and the abdominal pressure decreases, the omentum or intestines may be sucked into the trocar opening. Slightly lifting the endoscope 46 and slowly withdrawing it can temporarily close part of the air gap, reduce the negative pressure suction effect, and prevent the greater omentum from being brought into the trocar opening, forming a postoperative hernia or incarceration.

[0026] The endoscope 46 is adjusted through the coordinated operation of the rotating and tilting components. The rotating component drives the rotating sleeve 5 to rotate coaxially within the rotating groove 3 via the first driving component, achieving a 360° rotation of the endoscope 46. The tilting component drives the tilting sleeve 12 to rotate around the tilting axis 11 via the second driving component, which can flexibly adjust the tilt angle of the endoscope 46. The cooperation between the rotating and tilting components can quickly adapt to the field of view requirements of different surgeries, greatly improving the flexibility and accuracy of the endoscope 46 adjustment. The two symmetrically arranged clamping components can achieve a stable clamping of the endoscope 46. The cooperation between the arc-shaped guide rail 20 and the slider 21 allows the arc block 22 to move flexibly, so that the two arc blocks 22 can be joined to form a closed ring that can adaptively adjust with the tilt of the endoscope 46. Moreover, the locking components at the opposite ends of the arc blocks 22 can lock the clamping state, preventing the clamping from loosening or being over-clamped and damaging the instrument.

[0027] Example 2 Example 2 is largely the same in principle as Example 1, except that it also includes a foot pedal control assembly. This assembly includes a first forward pedal, a first reverse pedal, a second forward pedal, a second reverse pedal, a third forward pedal, a third reverse pedal, and a control board. The control board is configured as a microcontroller. All three pedals (first forward, first reverse, second forward, second reverse, third forward, and third reverse) are electrically connected to the control board. The first motor 7, the second motor 14, and the drive motor are also electrically connected to the control board. When the surgeon presses the first forward pedal, the control board... The control board receives an electrical signal and controls the first motor 7 to rotate forward. When the surgeon presses the first reverse foot pedal, the control board receives an electrical signal and controls the first motor 7 to rotate in reverse. When the surgeon presses the second forward foot pedal, the control board receives an electrical signal and controls the second motor 14 to rotate forward. When the surgeon presses the second reverse foot pedal, the control board receives an electrical signal and controls the second motor 14 to rotate in reverse. When the surgeon presses the third forward foot pedal, the control board receives an electrical signal and controls the drive motor to rotate forward. When the surgeon presses the third reverse foot pedal, the control board receives an electrical signal and controls the drive motor to rotate in reverse.
