[0026] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0027] Reference Figures 1-8The laparoscope with an expandable head of the present invention includes a laparoscope puncture device 1, a laparoscope body 11 is inserted into the laparoscope puncture device 1, and a puncture device supporting mechanism 2 is provided on the outer side of the laparoscope puncture device 1. The puncture device supporting mechanism 2 includes a bottom support plate 21 with an inverted bowl-shaped structure, a rotating seat 22 threadedly connected to the top of the bottom support plate 21, and a swing seat 23 installed in the rotating seat 22. The rotating seat 22 can rotate on the bottom support plate 21, and the swing seat 23 can swing on the rotating seat 22. The bottom support plate 21, the rotating seat 22 and the swing seat 23 are clamped and fixed on the outer side of the laparoscope puncture device 1 in sequence.

[0028] In the present invention, a threaded opening 211 is provided at the top of the bottom support plate 21, and the threaded opening 211 passes through the bottom support plate 21. An external thread 226 is integrally formed on the outer surface of the bottom end of the rotating seat 22, and the external thread 226 is threadedly connected to the threaded opening 211. By rotating the rotating seat 22 on the bottom support plate 21, the rotating seat 22 rotates on the bottom support plate 21 under the action of the external thread 226.

[0029] Specifically, a through opening 212 is provided on the top surface of the bottom support plate 21, one end of the through opening 212 is connected to the outer edge of the bottom support plate 21, and the other end of the through opening 212 is connected to the threaded opening 211, so that the laparoscope puncture device 1 can be placed into the threaded opening 211 from the outside of the bottom support plate 21 through the through opening 212.

[0030] Furthermore, a rubber pad 213 is tightly bonded to the outer edge of the bottom surface of the bottom support plate 21, so that when the bottom support plate 21 is placed on the patient's body, the rubber pad 213 can fit the patient's skin surface, so that the bottom support plate 21 can be stably placed on the patient's body surface.

[0031] It is worth noting that a movable groove 221 is provided at the top of the rotating seat 22, and the bottom of the movable groove 221 is in the shape of an arc. A bridge groove 223 is provided on the left and right inner walls of the movable groove 221, and a convex shaft 233 is integrally formed on the left and right end faces of the swing seat 23. By aligning the convex shaft 233 with the bridge groove 223, the swing seat 23 can be placed in the movable groove 221, so that the convex shaft 233 can be overlapped at the bottom of the bridge groove 223. At this time, the swing seat 23 can swing around the convex shaft 233 in the movable groove 221 under the action of the convex shaft 233.

[0032] A boss 224 is integrally formed on the outer end surface of the rotating base 22. A first handle bolt 225 is inserted into the boss 224. A threaded hole 2331 is defined at the end of the boss 233, distal from the swing base 23. The end of the first handle bolt 225 threads through the boss 224 and is inserted into the threaded hole 2331 for connection. When the first handle bolt 225 is tightened, the boss 233 presses against the sidewalls of the slot 223, thereby securing the swing base 23 within the movable slot 221. A through slot 222 is defined at the bottom of the movable slot 221. The through slot 222 extends through the bottom end surface of the rotating base 22. The laparoscopic trocar 1 passes through the through slot 222, and the side end surface of the through slot 222 communicates with the outer end surface, enabling the laparoscopic trocar 1 to be inserted into the rotating base 22 from the outside.

[0033] In the above scheme, a convex column 231 is integrally formed at the top of the swing seat 23, and a clamping groove 232 is provided on the front end surface of the swing seat 23. The clamping groove 232 vertically penetrates the swing seat 23 and the convex column 231. The side end surface of the clamping groove 232 is open, and the laparoscope puncture device 1 passes through the clamping groove 232, so that the laparoscope puncture device 1 can be inserted into the swing seat 23 from the outside, so that the puncture device support mechanism 2 can be sleeved on the laparoscope puncture device 1 under the action of the through port 212, the through groove 222 and the clamping groove 232, thereby achieving the purpose of installing the puncture device support mechanism 2.

[0034] Furthermore, a fixed clamp seat 234 is integrally formed at the left edge of the top of the clamping groove 232, and a movable clamp seat 235 is hinged at the rear end of the fixed clamp seat 234. When the laparoscopic puncture instrument 1 passes through the clamping groove 232, the fixed clamp seat 234 and the movable clamp seat 235 can be clamped on the outer side of the laparoscopic puncture instrument 1. When the laparoscopic puncture instrument 1 passes through the swing seat 23, the laparoscopic puncture instrument 1 can be clamped by the fixed clamp seat 234 and the movable clamp seat 235.

[0035] Furthermore, the rear end of the fixed clamp seat 234 is integrally formed with two hinge seats 2341 distributed vertically, with a hinge shaft 2342 inserted between the two hinge seats 2341. The rear end of the movable clamp seat 235 is integrally formed with a hinge platform 2351, which extends between the two hinge seats 2341. The hinge shaft 2342 vertically penetrates the hinge platform 2351 and is rotatably connected to the hinge platform 2351, allowing the movable clamp seat 235 to rotate at the rear end of the fixed clamp seat 234 under the action of the hinge shaft 2342. A second handle bolt 236 is inserted at the front end of the movable clamp seat 235. The end of the second handle bolt 236 can be threaded through the front end of the movable clamp seat 235, inserted into the front end of the fixed clamp seat 234, and threadedly connected.

[0036] When the laparoscopic puncture instrument 1 passes through the swing seat 23, the movable clamp seat 235 is closed and the second handle bolt 236 is tightened, so that the movable clamp seat 235 clamps the laparoscopic puncture instrument 1, thereby limiting the laparoscopic puncture instrument 1, so that the laparoscopic puncture instrument 1 can be fixed on the puncture instrument supporting mechanism 2, so that the angle of the laparoscopic puncture instrument 1 inserted into the patient's body remains unchanged, thereby preventing the laparoscopic puncture instrument 1 from causing compression to the patient's body tissue when it is subjected to the pressure of the laparoscope body 11.

[0037] In addition, an embedding groove 237 is provided on the rear end inner wall of the fixed clamp seat 234 and the rear end inner wall of the movable clamp seat 235, and a pad 2371 is embedded in the embedding groove 237. The pad 2371 protects the surface of the laparoscope puncture device 1 and prevents the laparoscope puncture device 1 from slipping on the swing seat 23.

[0038] The working principle of the laparoscope with an expandable head of the present invention is specifically as follows:

[0039] After the laparoscopic puncture device 1 is punctured into the patient's body and inserted into the laparoscope body 11, the head of the laparoscope body 11 is extended into the patient's body, so that the laparoscope body 11 provides images and lighting for the laparoscopic surgery; then the rotating seat 22 is rotated on the bottom support plate 21, so that the through groove 222 on the rotating seat 22 is aligned with the through hole 212 on the bottom support plate 21, so that the puncture device supporting mechanism 2 can be inserted into the outer surface of the laparoscopic puncture device 1, so that the laparoscopic puncture device 1 passes through the bottom support plate 21, the rotating seat 22 and the swing seat 23 in turn, and then the rotating seat 22 is rotated and the swing seat 23 is moved, so that the rotating seat 22 and the swing seat 23 are attached to the surface of the laparoscopic puncture device 1, and the bottom support plate 21 is aligned with the through groove 222 on the rotating seat 22 and the through hole 212 on the bottom support plate 21. The bottom end of the plate 21 can fit with the patient's skin. At this time, by tightening the first handle bolt 225, the convex shaft 233 is squeezed against the side wall of the groove 223 to achieve the purpose of fixing the swing seat 23 in the movable groove 221. Then, the movable clamp seat 235 is moved to rest against the laparoscopic puncture device 1, and the second handle bolt 236 is tightened to make the movable clamp seat 235 clamp the laparoscopic puncture device 1 to achieve the purpose of limiting the laparoscopic puncture device 1, so that the laparoscopic puncture device 1 can be fixed on the puncture device supporting mechanism 2, so that the angle of the laparoscopic puncture device 1 inserted into the patient's body remains unchanged, so as to prevent the laparoscopic puncture device 1 from causing compression to the patient's body tissue when it is subjected to the pressure of the laparoscope body 11.
