Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a technical solution: comprises a sheath tube 11 and a push rod 21; the front end of the sheath tube 11 mainly plays a role in puncture, the rear end of the sheath tube mainly plays a role in holding, and the push rod 21 mainly plays a role in telescopic clamping.

As shown in fig. 2, a baffle 14 is disposed on the rear end surface inside the sheath tube 11, a baffle 14 is further disposed on the rear portion inside the sheath tube 11, and a spring chamber is disposed between the two baffles 14.

As shown in fig. 3 and 5, a push plate 22 is arranged at the rear end of a push rod 21, a chuck 23 is arranged at the front end of the push rod 21, a V-shaped elastic sheet 25 is arranged between the middle parts of the two chucks 23, the V-shaped elastic sheet 25 has elasticity to enable the two chucks 23 to be opened outwards, and a limit plate 24 is arranged at the rear part of the push rod 21; the diameter of the limit plate 24 is larger than that of the push rod 21, and the outer diameter of the limit plate 24 is slightly smaller than the inner diameter of the sheath tube 11.

As shown in fig. 4, a through hole 15 for a push rod 21 to pass through is formed in the center of the baffle plate 14, the push rod 21 passes through the through hole 15 and penetrates through the interior of the sheath tube 11, the push plate 22 is located outside the sheath tube 11, the limit plate 24 is located in the spring chamber, a spring 3 is arranged in the spring chamber, the upper end of the spring 3 is in contact with the baffle plate 14, and the lower end of the spring 3 is in contact with the limit plate 24; when the spring 3 is in the fully extended state, the collet 23 is located inside the sheath 11, and when the spring 3 is in the fully compressed state, the collet 23 is located outside the sheath 11.

When the sheath tube is used, the front end of the sheath tube 11 is inserted into a vagina, the position of the front end part of the sheath tube 11 is observed through a laparoscope, when the tail end of a banding band is just positioned at the front end part of the sheath tube 11, the push rod 22 is pressed to push the push rod 21 forwards, the push rod 21 is stressed to move the clamping head 23 at the front end part forwards to extend out of the sheath tube 11, under the elastic action of the V-shaped elastic sheet 25, the two clamping heads 23 automatically open outwards, then the sheath tube 11 is moved towards the banding band direction to enable the banding band to be positioned between the two clamping heads 23, at the moment, the push rod 22 is loosened, due to no external force action, the spring 3 compressed by pressure can be stretched and rebounded to pull the push rod 22 backwards, when the position where the V-shaped elastic sheet 25 is connected with the clamping head 23 is pulled backwards into the sheath tube 11, the front end parts of the two clamping heads 23 are still positioned outside the sheath tube 11, at the moment, the two clamping heads 23 clamp the banding band in the middle part, and when the spring 3 is completely stretched, the clamp 23 holds the ligation band inside the sheath tube 11, and then the sheath tube 11 is withdrawn from the vagina, and the ligation band is also taken out of the body from the vagina to achieve external knotting.
