Description

A disposable uterine cavity tissue suction tube

technical field

The invention relates to a disposable uterine cavity tissue suction tube for obstetrics and gynecology, and belongs to the technical field of medical instruments.

Background technique

The traditional uterine cavity tissue suction tube is a stainless steel integral hollow tube with a slightly curved front part, a suction port on the side of the front end, and a suction device connected to the rear end through a rubber tube. This suction tube is repeatedly used, and if the disinfection is not strict, it is easy to cause cross-infection of patients.

Later, a disposable uterine cavity tissue suction tube appeared, which was made of medical polymer materials. This kind of disposable uterine cavity tissue suction tube mainly includes a hollow suction tube body. The front end of the suction tube body is closed and slightly bent to attract A suction opening is provided on the front side of the tube body, and a connecting body is connected to the rear end of the suction tube body for connecting with the suction device through a rubber tube. This kind of disposable uterine cavity tissue suction tube has the following defects: 1. Due to the split structure between the suction tube body and the connecting body, the connection part sometimes appears leaky, which affects the stable establishment of negative pressure in the tube during use. It affects the effect of the operation, and the split structure increases the assembly process, which is not conducive to reducing the cost; 2. There is usually only one suction port and it is far away from the front end of the suction tube body. 3. The design of the bending angle of the curved part of the front end of the suction tube is unreasonable, making it difficult for the suction tube to touch the hard-to-touch places such as the uterine horn and the sides of the fallopian tubes, which affects the The effect of surgery. In addition, the connection part of the existing disposable uterine cavity tissue suction tube and the rubber tube is a circular tube, and the rubber tube is easy to fall off during use, which affects the operation.

Contents of the invention

Aiming at the above-mentioned defects in the prior art, the present invention provides a disposable uterine cavity tissue suction tube which is reliable in use and capable of fully sucking up the tissues in the uterine cavity.

The present invention is implemented through the following technical scheme: a disposable uterine cavity tissue suction tube, comprising a suction tube body made of medical polymer material, the front end of the suction tube body is a suction tube head, the suction tube head There is a suction port on the side, and a connection structure made of medical polymer material is provided at the rear end of the suction tube body. The special feature is that the suction tube body and the connection structure are made in one body; The center line of the body forms an included angle a, and the included angle a is 10 degrees; the suction ports are three uniformly distributed along the circumference, and the distance L between the front end of the suction port and the front end of the suction tube head is 5mm -10mm.

In order to prevent the rubber tube from falling off when it is connected with the rubber tube, the rear end of the connection structure is a tapered tube with saw-shaped teeth on the outside of the tapered tube.

The present invention has a simple structure, and since the suction tube body and the connection structure adopt an integrated structure, there is no leakage problem between the suction tube body and the connection structure, which is conducive to the stable establishment of negative pressure in the tube and improves the surgical effect; The design of the bending angle of the tube head and the location and quantity of the suction port can make the suction tube head touch the hard-to-touch places such as the uterine horn and both sides of the fallopian tube, and suck up the tissues in the corner, greatly improving the surgical effect.

Detailed ways

Below in conjunction with accompanying drawing, the present invention will be further described:

As shown in the drawings, a disposable uterine cavity tissue suction tube includes a suction tube body 3 and a connecting structure 4 made of medical polymer materials. Suction pipe body 3 is hollow pipe, and its front end is suction pipe head 1, and the front end of suction pipe head 1 is closed, and the side of suction pipe head 1 is evenly provided with three suction ports 2 along its circumference, and the front end distance of described suction port 2 The distance L at the front end of the suction nozzle 1 is 5mm-10mm. The centerline of the suction tube head 1 and the suction tube body 3 forms an included angle a, and the included angle a is 10 degrees. The connection structure 4 is arranged at the rear end of the suction tube body 3, and its interior is hollow and communicates with the cavity of the suction tube body 3, and its rear end can be connected with the suction device through a rubber tube. The suction pipe body 3 and the connecting structure 4 are made in one body.

In order to prevent the rubber tube from falling off when it is connected with the rubber tube, the rear end of the connecting structure 4 in this embodiment is designed as a tapered tube with serrated teeth on the outside of the tapered tube.

Other parts in the present invention adopt the prior art, and will not be repeated here.
