Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical instruments, and in particular to a flexible laparoscope and stent. Background Technology
[0002] A laparoscope is a surgical instrument used to observe the inside of the abdominal cavity. In laparoscopic surgery, a cannula is first inserted into the patient's abdomen, and then the laparoscope is inserted into the cannula. The camera at the end of the laparoscope is used to capture images of the inside of the abdominal cavity.
[0003] After the laparoscope is inserted into the abdominal cavity, it needs to be supported and stabilized by the surgeon. The surgeon may also need to move the end of the laparoscope outside the abdominal cavity as needed, and adjust the angle of the camera at the end inside the abdominal cavity to adjust the angle of the images captured by the laparoscope. However, during the surgery, it is necessary to frequently observe the surgical situation, thus requiring the laparoscope to remain stable. Since the laparoscope is usually held by the surgeon, this requires prolonged holding and stabilization, which can lead to significant arm fatigue. Often, it is necessary to take turns supporting the laparoscope. Utility Model Content

Insertion rod. Detailed Implementation
[0028] The following combination Figure 1-6 The present invention will be described in further detail below.
[0029] Reference Figure 1 The flexible laparoscope includes a handheld part 1 and a tube part 2. A clamping tube 3 is fixed to one end of the handheld part 1 facing the tube part 2. The diameter of the clamping tube 3 is much larger than the diameter of the tube part 2.
[0030] Reference Figure 2 The laparoscopic support includes a main rod 4 and a swing rod 5. The swing rod 5 is located at the top of the main rod 4, and a gripper 6 is located at the end of the swing rod 5 away from the main rod 4. After positioning, the flexible laparoscope can be grasped by the gripper 6, which clamps onto the clamping tube 3. This avoids damage to the tube 2 caused by the gripper 6 directly gripping it, while the larger diameter of the clamping tube 3 facilitates stable clamping by the gripper 6, improving the stability of the gripper 6 in holding the flexible laparoscope. By using the laparoscopic support instead of manually holding the flexible laparoscope, the number of doctors who specialize in holding the flexible laparoscope can be reduced, and it is also convenient for the flexible laparoscope to be stably positioned for a long time.
[0031] Reference Figure 2 and Figure 3 The main rod 4 includes a support tube 41 and a lifting rod 42. The support tube 41 is vertically arranged, and the lifting rod 42 is disposed inside the support tube 41. A receiving groove 46 is formed on the top surface of the lifting rod 42, and a swing rod 5 is disposed inside the receiving groove 46. A fixing rod 47 passes through the top of the lifting rod 42, passes through the receiving groove 46, and passes through the swing rod 5 inside the receiving groove 46, so that the swing rod 5 can swing up and down around the fixing rod 47 as a pivot. Clamping nuts 48 are threaded to both ends of the fixing rod 47. By tightening the clamping nuts 48, the top of the lifting rod 42 can be retracted, thereby clamping the swing rod 5 in the receiving groove 46 and fixing the angle of the swing rod 5 when it is raised or lowered.
[0032] Reference Figure 2 and Figure 3 The lifting rod 42 has multiple positioning holes 44 on its side wall, arranged vertically. The support tube 41 has a connecting hole 43 that communicates with the positioning holes 44. The lifting rod 42 slides up and down within the support tube 41, allowing adjustment of the height of the swing rod 5. After adjusting the swing rod 5 to a suitable height, the positioning holes 44 and the connecting hole 43 are coaxially connected. Then, a pin 45 is inserted into the connecting hole 43, passing through the connecting hole 43 and entering the positioning hole 44, thus positioning the lifting rod 42 within the support tube 41.
[0033] Reference Figure 4 The swing arm 5 includes a connecting tube 51 and a telescopic rod 52. One end of the connecting tube 51 is inside the receiving groove 46 and is hinged to the lifting rod 42. The telescopic rod 52 is located at the other end of the connecting tube 51 and can slide within the connecting tube 51 to adjust the overall length of the swing arm 5. A friction block 53 is fixed on the telescopic rod 52. The friction block 53 is in close contact with the inner wall of the connecting tube 51, increasing the resistance when the telescopic rod 52 slides within the connecting tube 51. This ensures that the telescopic rod 52 remains stable within the connecting tube 51 even when the connecting tube 51 is facing downwards, achieving stepless adjustment of the length of the swing arm 5. A limit block 54 is fixed to the end of the connecting tube 51 away from the lifting rod 42. The limit block 54 is fixed to the inner wall of the connecting tube 51 to prevent the friction block 53 from dislodging from the connecting tube 51, thereby improving the stability of the telescopic rod 52 within the connecting tube 51.
[0034] Reference Figure 5The gripper 6 includes a mounting base 61 and a clamping block 62. A mounting groove 63 is formed on the side wall of the mounting base 61, penetrating the side wall. Two clamping blocks 62 are provided, both disposed within the mounting groove 63. Each clamping block 62 includes a pressing part 621, a connecting part 622, and a clamping part 623. One end of the connecting part 622 is within the mounting groove 63, and the other end extends out of the mounting groove 63. The pressing part 621 is fixed to the end of the connecting part 622 within the mounting groove 63, and the clamping part 623 is fixed to the end of the connecting part 622 outside the mounting groove 63. The end of the connecting part 622 within the mounting groove 63 is hinged to the mounting base 61, allowing the clamping parts 623 to move closer or further apart. The ends of the extrusion parts 621 that are far away from the connecting part 622 are far apart from each other, thus increasing the distance between the extrusion parts 621. A spring 64 is provided between the extrusion parts 621. One end of the spring 64 is fixed to the side wall of one extrusion part 621, and the other end is fixed to the side wall of another extrusion part 621. The spring 64 can handle compressed or natural states and can apply a thrust to the extrusion part 621.
[0035] Reference Figure 5 Under normal conditions, the clamping part 623 is clamped under the action of the spring 64. When it is necessary to clamp the flexible laparoscope, press the squeezing part 621, the two squeezing parts 621 move closer to each other, compress the spring 64, and open the clamping part 623, so that the clamping tube 3 of the flexible laparoscope can be inserted between the clamping parts 623. Release the squeezing part 621, the spring 64 rebounds, and the clamping part 623 clamps the clamping tube 3, thus completing the clamping of the flexible laparoscope.
[0036] Reference Figure 6 The mounting base 61 has an insertion rod 65 on the side facing the telescopic rod 52. The swing rod 5 has an insertion hole 55 on the side facing the mounting base 61 for inserting the insertion rod 65. A fastening screw 56 is threaded onto the swing rod 5, extending into the insertion hole 55. Loosening the fastening screw 56 allows the mounting base 61 to rotate, adjusting the angle of the flexible laparoscope; tightening the fastening screw 56 allows the angle of the mounting base 61 on the telescopic rod 52 to be positioned, thereby positioning the flexible laparoscope.
[0037] The implementation principle of this utility model embodiment is as follows: During surgery, after the flexible laparoscope is positioned, the height of the main rod 4 of the laparoscope support, the length and swing angle of the swing rod 5, and the angle of the clamp 6 are adjusted according to the position of the flexible laparoscope. The squeezing part 621 of the clamping block 62 is pressed, so that the clamping block 62 clamps the clamping tube 3 of the flexible laparoscope. At this time, the doctor who was originally supporting the flexible laparoscope can no longer provide support and participate in other aspects of the surgery.
[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
