DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0024] Example 1
[0025] As attached Figure 1 As shown, a subcutaneous water injection needle for laparoscopic thyroid surgery includes a flexible water tube 1, a positioning catheter 2 is sheathed on the outside of the flexible water tube 1, a connecting plate 3 is connected to one side of the positioning catheter 2, and a valve body is connected to the tail end of the flexible water tube 1.
[0026] Through the above structure, the connecting plate 3 is embedded and installed inside the side wall of the dilator cylinder to connect the positioning catheter 2 to the dilator cylinder. The positioning catheter 2 and the flexible water conduit 1 have small diameters. The side wall of the port of the positioning catheter 2 is a ring structure. When it is sent to the surgical space with the dilator incision, it will not cause additional damage to the skin, blood vessels and other tissues. After one end of the positioning catheter 2 enters the surgical space, the flexible water conduit 1 is passed through the positioning catheter 2 into the surgical space, and the flexible water conduit 1 is positioned by the positioning catheter 2 to prevent the flexible water conduit 1 from shaking and causing damage to the skin, blood vessels and other tissues. The flexible water conduit 1 is opened and closed by the valve body to prevent the expansion fluid from flowing out. The specific structure is as follows:
[0027] Combined with attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the valve body includes a sleeve 4 connected to the flexible water pipe 1, and a through hole 5 connected to the flexible water pipe 1 is provided at an eccentric position at the bottom of the sleeve 4. A rotating block 6 rotates inside the sleeve 4, and a water guide channel 7 passes through the inside of the rotating block 6. A water inlet pipe 8 connected to the water guide channel 7 is installed on the upper side of the rotating block 6, and a connecting sleeve 9 is installed at the other end of the water inlet pipe 8.
[0028] Through the above structure, after the flexible water conduit 1 is sent to the operation space through the positioning catheter 2, the water inlet pipe 8 is rotated, the rotating block 6 is rotated in the sleeve 4, the water guide channel 7 is connected with the through hole 5, the injection pipe needle is inserted into the connecting sleeve 9, the expansion liquid in the injection pipe is sent to the water inlet pipe 8, and the expansion liquid is sent to the flexible water conduit 1 through the water guide channel 7 and the through hole 5, and the expansion liquid is sent to the inside of the operation space through the flexible water conduit 1. When the amount of expansion liquid sent is sufficient, the water inlet pipe 8 is rotated, the rotating block 6 is rotated in the sleeve 4, the water guide channel 7 port is tightly attached to the bottom of the sleeve 4, the water guide channel 7 is blocked with the through hole 5, and the expansion liquid in the operation space is prevented from being discharged from the flexible water conduit 1, which affects the subsequent expansion liquid sent to the operation space.
[0029] Combining the accompanying drawings Figure 5 and the accompanying drawings Figure 6 As shown, the upper port of the water guide channel 7 is located at the center of the rotating block 6, and the lower port is located eccentrically at the rotating block 6.
