[0038] See also Figure 1-Figure 5 The utility model provides a laparoscope assembly, including a peritoneal tube 1, a camera module, an LED light and an end head 2. The distal end of the peritoneal tube 1 is provided with an interconnected plug interface and a third mounting groove 16, the plug interface is located on the distal side of the third mounting groove 16, the distal end of the plug interface passes through the distal end of the peritoneal tube 1, and the end head 2 is embedded in the plug interface. A first mounting groove 21 and a second mounting groove 22 are provided in the end head 2, the distal ends of the first mounting groove 21 and the second mounting groove 22 are closed, the proximal ends of the first mounting groove 21 and the second mounting groove 22 are open, and the bottoms of the first mounting groove 21 and the second mounting groove 22 are transparent structures.

[0039] The third mounting slot 16 is connected to the first mounting slot 21 and the second mounting slot 22. The camera module is arranged in the first mounting slot 21, and the LED lamp is arranged in the second mounting slot 22. A battery module and a wireless communication module are provided in the third mounting slot 16. The battery module is respectively connected to the camera module box LED lamp, and the wireless communication module is connected to the camera module.

[0040] The camera module is a miniature camera module, and the outer diameter of the abdominal tube 1 is no more than 3 mm, so that the laparoscope assembly can be used in outpatient examinations.

[0041] The camera module of the present invention adopts a miniature camera module, so that the radial dimension of the first mounting groove 21 is smaller, thereby making the radial dimension of the entire end 2 smaller, so that the outer diameter of the abdominal tube 1 can be controlled within 3 mm. Therefore, during the operation, there is no need to make an incision in the patient's abdomen. A smaller cannula can be directly used to pierce the patient's abdomen, so that the laparoscope assembly can enter the patient's abdomen for examination. Since the wound is small, the harm to the patient during the operation is small, and after the operation is completed, it is also convenient for the patient to recover, and the laparoscope assembly of the present invention can be used in outpatient examinations.

[0042] A third mounting groove 16 can also be formed in the abdominal tube 1, and the third mounting groove 16 is connected to the plug interface. When the end 2 is connected to the plug interface, the third mounting groove 16 is connected to the first mounting groove and the second mounting groove. A battery module and a wireless communication module are arranged in the third mounting groove 16. The electromagnetic module is respectively arranged with the micro camera module and the LED light to power the micro camera module and the LED light. The wireless communication module is connected to the micro camera module to send the images taken by the micro camera module to the outside.

[0043] The image information is sent wirelessly, so that no communication channel is required in the abdominal tube 1, and thus the outer diameter of the abdominal tube 1 can be set to be smaller.

[0044] The abdominal tube 1 includes an inner tube 13 and an outer tube 12. A first water channel 131 is provided on the outer wall of the inner tube 13, and a second water channel 121 is provided on the inner wall of the outer tube 12. The inner tube 13 is located inside the outer tube 12, and the outer wall of the inner tube 13 is in contact with the inner wall of the outer tube 12; in the radial direction of the abdominal tube 1, the first water channel 131 and the second water channel 121 are interlocked to form a combined water channel.

[0045] An annular groove 122 is provided on the inner wall of the distal end of the outer tube 12, and a water spraying area is provided on the outer wall of the inner tube 13. The annular groove 122 of the water spraying area radially corresponds to the annular groove 122, and the water spraying area is provided with a plurality of water holes 132. The plurality of water holes 132 are evenly arranged along the circumference of the water spraying area.

[0046] When the end head 2 is embedded in the plug-in port, the distal end of the end head 2 is located on the proximal side of the distal end of the abdominal tube 1, so that a flushing space 15 is formed in the plug-in port. The flushing space 15 is located on the distal side of the end head 2, and the water hole 132 is connected to the flushing space 15.

[0047] The inner tube 13 and the outer tube 12 together constitute the abdominal tube 1, wherein the inner tube 13 is located on the inner side and the outer tube 12 is located on the outer side. The outer wall of the inner tube 13 is fitted with the inner wall of the outer tube 12. A first water channel 131 is provided on the inner and outer outer walls, and a second water channel 121 is provided on the inner wall of the outer tube 12. When the abdominal tube 1 is formed, the first water channel 131 and the second water channel 121 are interlocked with each other to form a combined water channel. The distal end of the combined water channel is connected with the annular groove 122, so that water (physiological saline) can be supplied to the annular groove 122 through the combined water channel. The water hole 132 is connected with the annular groove 122, so that physiological saline can be sprayed out through the water hole 132. The physiological saline is sprayed from the water hole 132 to the flushing space 15, thereby flushing the distal end of the end 2.

[0048] During surgery, the distal end of tip 2 may be contaminated by blood in the abdominal cavity, thereby affecting the camera effect. The blood at the distal end of tip 2 is flushed away by physiological saline, so that the laparoscope assembly can clearly capture the image in the abdominal cavity, ensuring the surgical effect.

[0049] Each of the water holes 132 points to the central area of the distal end of the terminal 2, so that the saline is sprayed toward the distal end surface of the terminal 2 to clean the distal end surface of the terminal 2.

[0050] The abdominal tube 1 includes a bend adjustment section 11 located proximal to the insertion port, with a preset distance between the section 11 and the insertion port. The provision of bend adjustment section 11 enables controlled bending of the abdominal tube 1. During surgery, the bending angle of the section 11 can be adjusted to change the orientation of the distal end of the abdominal tube 1, enabling imaging of desired locations within the abdominal cavity.

[0051] In the bending section 11, the inner tube 13 is embedded with an adjustable steel pipe, which includes a steel pipe body 3 and a bending control wire connected to the steel pipe body 3. The steel pipe body 3 is provided with a plurality of deformation openings that pass through a single side wall of the steel pipe body 3. The deformation openings extend to both sides along the circumference of the steel pipe body 3. The plurality of deformation openings are arranged at intervals along the axial direction of the steel pipe body 3.

[0052] The plurality of deformation openings 31 are divided into a first deformation opening group, a second deformation opening group, a third deformation opening group, and a fourth deformation opening group. The deformation openings in each deformation opening group are positioned uniformly in the circumferential direction. In the circumferential direction, the first deformation opening group, the second deformation opening group, the third deformation opening group, and the fourth deformation opening group are staggered 90 degrees in the clockwise direction.

[0053] A communication channel is formed in the inner tube 13 , and the distal end of the bending control wire is connected to the distal end side of the steel tube body 3 , passes through the interior of the steel tube body 3 , and extends from the proximal end of the communication channel.

[0054] The steel pipe body 3 is provided with a deformation opening 31 , which is C-shaped, and a plurality of deformation openings are arranged at intervals along the axial direction, so that the steel pipe is bent in the opening direction of the deformation opening.

[0055] For ease of understanding, the deformation openings of the first deformation opening group are referred to as the first deformation opening, the deformation openings of the second deformation opening group are referred to as the second deformation opening, the deformation openings of the third deformation opening group are referred to as the third deformation opening, and the deformation openings of the fourth deformation opening group are referred to as the fourth deformation opening. The first deformation opening and the third deformation opening are radially opposite to each other, and the second deformation opening and the fourth deformation opening are radially opposite to each other. When the steel pipe body 3 is controlled by the bending wire to bend toward the opening direction of the first deformation opening, the opening of the first deformation opening deforms and the opening of the third deformation opening increases, thereby causing the bent pipe section to bend toward the opening direction of the first deformation opening. Similarly, when the second deformation opening decreases and the fourth deformation opening increases, the steel pipe body 3 is bent toward the opening direction of the second deformation opening. When the third deformation opening decreases and the first deformation opening increases, the steel pipe body 3 is bent toward the opening direction of the third deformation opening. When the fourth deformation opening decreases and the second deformation opening increases, the steel pipe body 3 is bent toward the opening direction of the fourth deformation opening. It can be seen that the above deformation openings enable the steel pipe body 3 to be bent in any desired manner.

[0056] The distal end of the bending control wire is connected to the distal side of the steel pipe body 3, and extends from the proximal end of the connecting channel through the interior of the steel pipe body 3. Therefore, when it is necessary to control the bending of the steel pipe body 3, the bending control wire can be pulled at the proximal end to make the steel pipe body 3 bend in a controlled manner.

[0057] There are four bending control wires, namely a first bending control wire, a second bending control wire, a third bending control wire and a fourth bending control wire. The first bending control wire corresponds to the first deformation opening group, the second bending control wire corresponds to the second deformation opening group, the third bending control wire corresponds to the third deformation opening group, and the fourth bending control wire corresponds to the fourth deformation opening group. Among the corresponding bending control wires and deformation opening groups, the bending control wires and the deformation opening group are located on the same side of the bending adjustment section.

[0058] Pulling the first bending control wire bends the steel tube body 3 toward the opening of the first deformation opening, pulling the second bending control wire bends the steel tube body 3 toward the opening of the second deformation opening, pulling the third bending control wire bends the steel tube body 3 toward the opening of the third deformation opening, and pulling the fourth bending control wire bends the steel tube body 3 toward the opening of the fourth deformation opening. Thus, the corresponding bending control wire can be pulled as needed to controllably change the orientation of the distal end of the abdominal tube 1.

[0059] The inner tube 13 is provided with a wire threading hole, the position of which is consistent with the distal end of the steel tube body 3, through which the bending control wire enters the connecting channel, so that most of the bending control wire is located in the connecting channel, reducing the resistance encountered when pulling the bending control wire.

[0060] It should be understood that the above-mentioned embodiments are merely illustrative and non-restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present invention.
