Uterus stent pushing device

Abstract

The utility model relates to the technical field of uterine stent pushing, in particular to a uterine stent pushing device which comprises a pushing assembly, a pushing assembly and a pushing assembly. The pushing assembly comprises a sleeve; the push rod is connected to one end of the sleeve; the sleeve U-shaped opening is formed in the other end of the sleeve; and a limiting block is arranged outside the sleeve in a sleeving manner. The U-shaped opening at the front end of the plastic sleeve is small in front and large in rear, so that the uterus support can be effectively fixed and does not fall off in a free state.

Description

Technical Field

[0001] This utility model relates to the field of uterine stent delivery technology, specifically a uterine stent delivery device. Background Technology

[0002] A uterine stent is inserted through the vaginal opening to prevent uterine adhesions. A special uterine stent pusher can be used to insert the stent into the uterine opening.

[0003] Currently, hospitals clinically use cervical forceps for placement. This method requires medical personnel with specialized skills and may even cause secondary damage to the uterine wall.

[0004] In response to the problems mentioned above, we propose a uterine stent delivery device. Utility Model Content

[0005] The purpose of this invention is to provide a uterine stent delivery device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A uterine stent delivery device, comprising:

[0008] Push component, used to push the uterine stent body;

[0009] The push component includes:

[0010] casing;

[0011] A push rod connected to one end of the sleeve;

[0012] A U-shaped opening in the casing at the other end;

[0013] A limiting block is fitted around the outside of the sleeve.

[0014] Preferably, the sleeve is made of PP thin tube material.

[0015] Preferably, the push rod and the limiting block are injection molded using a plastic mold.

[0016] Preferably, the U-shaped opening of the sleeve is formed by hot-melt mold and stamping.

[0017] Preferably, the U-shaped opening of the sleeve has a "U"-shaped structure, narrow at the front and wide at the back, with a rounded head design.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model uses a U-shaped opening at the front end of a malleable sleeve, which is smaller at the front and larger at the back, to effectively fix the uterine support and prevent it from falling off in a free state.

[0020] This invention involves inserting a uterine stent and then using a built-in push rod to detach the stent from the U-shaped opening under external force.

[0021] The U-shaped opening of this invention has an R-shaped tip that does not damage the uterine mucosa during operation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-2 A uterine stent delivery device, comprising:

[0028] Push component, used to push the uterine stent body 4;

[0029] The push component includes:

[0030] Sleeve 1;

[0031] Push rod 2 is connected to one end of sleeve 1;

[0032] A U-shaped opening 5 is provided at the other end of the sleeve 1;

[0033] A limiting block 3 is fitted on the outside of the sleeve 1.

[0034] The sleeve 1 is made of PP thin tube material, the push rod 2 and the limiting block 3 are made of plastic injection molding, and the sleeve U-shaped opening 5 is made of hot melt mold and stamped. The sleeve U-shaped opening 5 has a "U" shaped structure, narrow at the front and wide at the back, with a round head design.

[0035] The method of using the uterine stent delivery device includes the following steps:

[0036] Before placement, the part with the round hole at the front end of the uterine stent body 4 is inserted into the U-shaped opening 5 of the cannula 1. The push rod 2 is inserted into the cannula 1 and then inserted into the uterus through the vagina. Next, the limiting block 3 is moved according to the depth of insertion. When the uterine stent body 4 is pushed into the designated position, the push rod 2 is pushed to disengage the uterine stent body 4 from the U-shaped opening 5 of the cannula 1. After the push is completed, the cannula 1 and the push rod 2 are removed.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
