Description

Technical Field

[0001] The utility model relates to the technical field of electric laparoscope power supplies, in particular to a power supply device for an electric laparoscope. Background Art

[0002] The laparoscopic stapler is one of the important instruments in laparoscopic surgery. It replaces traditional manual suturing and uses titanium nails to separate or anastomose tissues. It is easy and quick to operate and greatly shortens the operation time. The laparoscopic stapler makes the anastomosis that is difficult to perform manually in a narrow surgical field and deep areas easy, accurate, firm and reliable.

[0003] Electric laparoscopic staplers are all equipped with lithium battery packs to provide power for the instruments, thereby driving various mechanical actions of the instruments, such as closing, cutting and suturing. However, the battery packs of electric laparoscopy have certain disadvantages and impracticality in various aspects. For example, in terms of enterprise cost, the battery pack is assembled from 4 lithium batteries with a voltage of 3V. The price of lithium batteries is relatively high, and the assembly process is complicated, which increases the processing cost; in terms of stability in use, the 4 lithium batteries in the battery pack are welded in series by metal connecting plates. It is possible that due to poor welding, transportation vibration, falling before use and other reasons, the battery contact is poor, resulting in inability to perform surgery. Batteries are also a kind of consumable items. During storage, multiple uses in an operation, or firing thick tissues during surgery, the battery voltage will be insufficient, which will also cause the operation to fail to proceed normally; in terms of environmental protection, lithium batteries are non-renewable energy sources and need to be destroyed after use. As we all know, the destruction of batteries has very serious damage to the environment. Utility Model Content

[0038] An inlet hole 52 for the power cord 1 to pass through and an outlet hole 53 for the power cord 1 to pass through are provided on the peripheral side wall of the circular ring 512 of the storage shell 51 . The inlet hole 52 is located on a side close to the power host 2 .

[0039] A reel 54 is rotatably arranged inside the storage housing 51, and the power cord 1 is wound around the reel 54. The two axial sides of the reel 54 are coaxially fixedly connected to the limiting plates 55. The power cord 1 is located between the two limiting plates 55.

[0040] When one end of the power cord 1 connected to the electric laparoscope 4 is pulled and extended, the winding shaft 54, the limit plate 55, and the limit shaft 56 rotate counterclockwise together, and the ratchet 57 and the pawl 58 are rotatable. The ratchet 57 rotates counterclockwise with the limit shaft 56. When the power cord 1 stops extending, the pawl 58 locks the ratchet 57, and the ratchet 57 cannot rotate clockwise, so that the winding shaft 54, the limit plate 55, and the limit shaft 56 are all fixed.

[0041] There is an accommodation space between the pawl 58 and the limiting plate 55 for the pawl 58 to move. The pawl 58 slides along the axial direction of the limiting shaft 56. The pawl 58 can slide into the accommodation space and disengage from the ratchet 57. The driving plate 59 is slidably connected to the mounting shaft 571, and the driving plate 59 abuts against the pawl 58. The pawl 58 is provided with an installation hole 581 for the mounting shaft 571 to pass through, and a guide block 5811 is provided on the inner wall of the installation hole 581. A guide groove 5712 for the guide block 5811 to slide is provided on the outer peripheral wall of the mounting shaft 571, and the guide groove 5712 is provided along the axial direction of the mounting shaft 571.

One end of the telescopic spring 5713 abuts against the limit plate 55, and the other end of the telescopic spring 5713 abuts against the pawl 58. The telescopic spring 5713 applies a force to the pawl 58 to move the pawl 58 away from the limit plate 55. A positioning ring 5714 is also fixedly provided on the mounting shaft 571.

[0043] The limiting shaft 56 is provided with a second torsion spring 561, which applies a force to the limiting shaft 56 to rotate the limiting shaft 56 clockwise to reel in the power cord 1. A fixing ring 562 is coaxially fixed to the limiting shaft 56, and the fixing ring 562 is located on the side of the ratchet 57 away from the limiting plate 55.

[0044] When the line needs to be released, the user holds the storage shell 51 with one hand and pulls the power cord 1 near one end of the electric laparoscope 4 with the other hand. The ratchet 57 rotates counterclockwise. When it is pulled to the required length, the power cord 1 is released. The second torsion spring 561 drives the limiting shaft 56 to rotate clockwise, but under the action of the pawl 58, the pawl 58 locks the rotation of the ratchet 57, so that the winding shaft 54 ​​cannot rotate, and the length of the power cord 1 is automatically locked. The operation is quick and convenient.

[0045] When the power cord 1 needs to be reeled in, the driving rod 591 is pushed toward the direction close to the limit plate 55 by overcoming the force of the telescopic spring 5713. The driving rod 591 pushes the pawl 58 toward the direction close to the limit plate 55 into the accommodating space through the driving plate 59. The pawl 58 disengages from the ratchet 57. Under the action of the second torsion spring 561, the ratchet 57 rotates clockwise to automatically reel in.

[0046] The ends of the limit shafts 56 that are away from each other pass through the storage shell 51 and are rotatably connected to the circular plate 511 of the storage shell 51. The inner wall of the circular plate 511 is provided with a receiving groove 5111 for the limit shaft 56 to rotate. The distance between the inner bottom walls of the two receiving grooves 5111 is consistent with the distance between the sides of the two limit shafts 56 that are away from each other, so that the winding shaft 54 ​​and the limit shaft 56 can be axially fixed.

[0047] A positioning rod 551 is provided on the side of the limit plate 55 that is away from each other, and a positioning ring groove 552 for the positioning rod 551 to slide is opened on the inner wall of the circular plate 511 of the storage shell 51, thereby improving the stability of the winding shaft 54, the limit plate 55, and the limit shaft 56 when they rotate relative to the storage shell 51.

[0048] A partition plate 6 is coaxially connected to the outer peripheral side wall of the winding shaft 54 ​​, and the outer diameter of the partition plate 6 is consistent with the outer diameter of the limiting plate 55 .

[0049] A through slot 61 for the power cord 1 to pass through is provided on the end surface of the partition 6.

The widths of the first space 62 and the second space 63 are both adapted to the outer diameter of the power cord 1.

[0050] When winding the power cord 1, first remove the circular plate 511 on one side of the storage shell 51, then let the power cord 1 enter the first space 62 from the wire entry hole 52 and wind it around the winding shaft 54 ​​for one circle, then fix the circular plate 511 that has just been removed to the circular ring 512 with screws 513, so that the limit shaft 56 is inserted into the corresponding accommodating groove 5111, and the positioning rod 551 is inserted into the corresponding positioning ring groove 552, then remove the other circular plate 511, pass the power cord 1 through the yielding groove 61 into the second space 63, wind it around the winding shaft 54 ​​for several circles, then pass through the wire exit hole 53 and penetrate into the shell of the electric laparoscope 4 to connect with the wiring terminal of the electric laparoscope 4, finally fix the circular plate 511 to the circular ring 512 with screws 513.
