Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a side-sealed multi-channel laparoscope surgery platform. Background Art

[0002] The multi-channel laparoscopic surgical platform is an innovative technology used in laparoscopic surgery. It allows multiple instruments to enter the abdominal cavity simultaneously through a single puncture port for operation, breaking through the bottleneck of cross-operation in traditional single-port laparoscopic surgery and improving surgical efficiency and safety.

[0003] The existing multi-channel laparoscopic surgical platform has some defects. For example, the Chinese invention patent with publication number 221308329U specifically discloses a multi-channel single-hole laparoscopic surgical channel device, including a multi-hole operating platform, a peritoneal tube, a connecting device, an instrument tube, and a sealing outer ring. The connecting device is composed of a connecting piece and a clamping mechanism. The connecting piece is provided with an inner cavity, and the two ends have a first and a second opening connected to the inner cavity. The instrument tube is inserted into the first opening and connected through a sealing piece, and the peritoneal tube is inserted into the second opening. An accommodating portion is circumferentially arranged on the inner wall of the inner cavity to surround the sealing outer ring. The clamping mechanism is installed on the connecting piece, which is used to squeeze the connecting piece inward, compress the sealing outer ring, and achieve sealing.

[0004] In this patent, when the sealing ring is sleeved on the instrument tube, it can be inserted between the instrument tube and the boss, and then the instrument tube is inserted into the connector so that the sealing ring is connected to the sealing part to achieve sealing. Although the sealing ring can be sealed by inserting it into the instrument tube and the connector, the upper and lower parts of the multi-channel laparoscopic surgical platform press the sealing ring tightly, and the upper and lower interference seals have high dimensional requirements. However, the multi-hole operation requires rotation, and it is easy for the sealing ring to be locked when it is inserted into the instrument tube and the connector, making it difficult to rotate. In addition, the structural stability of this implementation method is poor, the number of parts required is large, the processing technology of the parts is complicated, and it is not conducive to assembly. Summary of the invention

[0005] The purpose of the present invention is to provide a side-sealed multi-channel laparoscopic surgical platform, which adopts side sealing to improve the sealing method of the prior art, and while improving the overall structural stability, reduces the number of parts, process and precision requirements, and has the advantages of easy promotion, flexible rotation, convenient operation and easy assembly.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A side-sealed multi-channel laparoscopic surgical platform comprises a connecting disk and a platform top cover arranged on the upper part of the connecting disk, wherein the platform top cover can rotate circumferentially relative to the connecting disk, and the platform top cover comprises a sealing cover body and a pressure ring assembly connected to the bottom of the sealing cover body; the connecting disk comprises a connecting ring and a base embedded in the connecting ring, an extension portion extending upward from the surface of the connecting ring is provided on the base, a longitudinally limited locking mechanism is provided between the extension portion and the pressure ring assembly, and a side stop mechanism for sealing is also provided between the upper end of the connecting ring and the pressure ring assembly.

[0008] Compared with the prior art, the advantages of the present invention are:

[0009] 1. By setting the side stop mechanism, an effective side seal is achieved between the connection disk and the platform top cover, which reduces the precision requirements for parts and facilitates promotion. At the same time, it ensures that the platform top cover can be flexibly rotated relative to the connection disk, avoiding the problem of the platform being unable to rotate due to the jamming of the sealing ring in the prior art, and improving the convenience and flexibility of surgical operations;

[0010] 2. The locking mechanism provided between the extension part and the intermediate pressure ring not only achieves a stable connection between the platform top cover and the connection plate, but also reduces the number of assembly parts, making the assembly process easier;

[0011] 3. The present invention adopts side sealing, and its sealing structure is not only more streamlined than the prior art, but also improves the sealing effect on the basis of the streamlined structure. BRIEF DESCRIPTION OF THE DRAWINGS
