Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a split-type interventional dilation catheter. Background Technology

[0002] The rod-shaped water balloon prostate dilation procedure is a minimally invasive surgery used to treat benign prostatic hyperplasia. It uses a cylindrical water (air) balloon prostate dilation catheter. The main body of the catheter has four lumens, which are divided into a urinary catheterization lumen, an irrigation lumen, and two high-pressure water balloon lumens inside and outside the lumen. The four lumens are respectively connected to the urinary catheter, the irrigation lumen, and two water injection tubes.

[0003] During the procedure, a catheter insertion aid is inserted into the urinary catheter and the end of the catheter lumen. The catheter is then inserted into the urethra and up to the bladder using the insertion aid. The patient is usually in the lithotomy position with both legs fixed to a leg rest. During the procedure, the surgeon usually operates between the patient's legs to facilitate control of the catheter insertion depth. However, the space between the patient's legs is limited, and the assistant is usually positioned outside the patient's legs. To facilitate the surgeon's operation, the injection tubing of the cylindrical water (air) balloon prostate dilation catheter is relatively long and close to the urinary catheter. When the injection tubing is not in use, it is prone to slipping, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a split-type interventional dilation catheter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A split-type interventional dilation catheter, comprising:

[0007] The device includes an insertion tube, a flushing tube, a urinary catheterization tube, and two water injection tubes. The insertion tube comprises a flushing chamber, a urinary catheterization chamber, and two high-pressure water balloon chambers. One end of the insertion tube is fixedly connected to a connecting shell, and one end of the connecting shell is fixedly connected to four locking tubes. The flushing chamber, the urinary catheterization chamber, and the two high-pressure water balloon chambers are all fixedly connected to one end of the four locking tubes via catheters. The flushing tube corresponds to the flushing chamber, and one end of the flushing tube is movably locked to the locking tube connected to the flushing chamber. The urinary catheterization tube corresponds to the urinary catheterization chamber, and one end of the urinary catheterization tube is movably locked to the locking tube connected to the urinary catheterization chamber. The two water injection tubes correspond to the two high-pressure water balloon chambers, and one end of each of the two water injection tubes is movably locked to the locking tube connected to the two high-pressure water balloon chambers. Metal wires are fixedly connected to the outer walls of both water injection tubes.

[0008] Furthermore, all the card connectors are made of rubber.

[0009] Furthermore, multiple elastic clips are slidably engaged on the outer walls of both metal wires, and a magnet is fixedly connected to the bottom surface of each elastic clip.

[0010] Furthermore, each of the elastic clips is C-shaped.

[0011] Furthermore, the elastic retainer is made of plastic.

[0012] Furthermore, the two water injection tubes are equipped with rubber strips, and the rubber strips contain iron wires.

[0013] Furthermore, an adhesive sticker is fixedly bonded to one side of the rubber strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By connecting the flushing tube, urinary catheter, and two water injection tubes to their corresponding tubes, and then manually shaping the two water injection tubes by bending the two metal wires, the user can cut the rubber band to a suitable length and attach it to the patient's clothing or a nearby frame using adhesive tape. The elastic clip is then attached to the shaped metal wire and finally fixed to the rubber plate using a magnet. This process utilizes the shaping ability of the metal wire and the magnetic attraction between the elastic clip and the rubber plate to secure the water injection tubes and prevent them from shifting.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 In this embodiment of the present invention, a split-type interventional dilation catheter includes:

[0023] The device includes an insertion tube 100, a flushing clamp tube 200, a urinary catheter clamp tube 300, and two water injection clamp tubes 400. The insertion tube 100 includes a flushing chamber, a urinary catheterization chamber, and two high-pressure water balloon chambers. One end of the insertion tube 100 is fixedly connected to a connecting shell 110, and one end of the connecting shell 110 is fixedly connected to four clamping tubes 111. The flushing chamber, the urinary catheterization chamber, and the two high-pressure water balloon chambers are all fixedly connected to one end of the four clamping tubes 111 via catheters. The flushing clamp tube 200 corresponds to the flushing chamber and... One end of the flushing tube 200 is connected to the flushing chamber via a movable locking tube 111. The urinary catheter 300 corresponds to the urinary catheter chamber, and one end of the urinary catheter 300 is connected to the urinary catheter chamber via a movable locking tube 111. Two water injection tubes 400 correspond to two high-pressure water balloon chambers, and one end of each water injection tube 400 is connected to the locking tube 111 of the two high-pressure water balloon chambers via a movable locking tube. Metal wires 410 are fixedly connected to the outer walls of both water injection tubes 400.

[0024] Specifically, the main body of a typical cylindrical water (air) balloon prostate dilation catheter has four lumens: a urinary catheterization lumen, an irrigation lumen, and two high-pressure water balloon lumens (inner and outer). The insertion tube 100 is the cylindrical water (air) balloon prostate dilation catheter, with all four lumens connected to the catheters. All four catheters are located inside the connecting shell 110, and each of the four catheters is connected to one of the four locking tubes 111. In use, the two water injection locking tubes 400, the urinary catheter locking tube 300, and the irrigation catheter locking tube 200 are inserted into their corresponding locking tubes 111. The user can then manually bend the metal wire 410 on the two water injection locking tubes 400 to control their shape, allowing the user to bend them into a suitable position and hang them on the patient's legs or other areas to secure their position. The metal wire 410 can be made of copper, iron, or other metals.

[0025] Example 1

[0026] like Figure 1 and Figure 3As shown, in this embodiment, each of the retaining tubes 111 is made of rubber, and multiple elastic retaining tubes 430 are slidably engaged on the outer walls of the two metal wires 410. A magnet 440 is fixedly connected to the bottom surface of each elastic retaining tube 430. Each elastic retaining tube 430 is C-shaped and made of plastic.

[0027] In this embodiment, the retaining tube 111, the two water injection retaining tubes 400, the urinary catheter retaining tube 300, and the flushing retaining tube 200 are all made of silicone. This allows the retaining tube 111 to fit tightly with one end of the two water injection retaining tubes 400, the urinary catheter retaining tube 300, or the flushing retaining tube 200, preventing leakage at the retaining tube 111. The elastic retaining sleeve 430 is made of plastic and has a certain degree of elasticity. During use, the elastic retaining sleeve 430 can be clipped onto the metal wire 410 and then attracted to a nearby iron object with a magnet 440, which further secures the metal wire 410 and the water injection retaining tube 400. After use, the elastic retaining sleeve 430 and the magnet 440 can be removed from the metal wire 410 for cleaning and reuse.

[0028] like Figure 1 and Figure 4 As shown, in this embodiment, the two water injection tubes 400 are equipped with rubber strips 420, and iron wires 421 are installed inside the rubber strips 420.

[0029] In practice, the rubber band 420 is wrapped with iron wire 421. When in use, the rubber band 420 can be fixed to the patient's leg. Then, the two water injection tubes 400 are attracted and fixed to the iron wire 421 inside the rubber band 420 using magnets 440 and elastic clips 430. This makes it easy to fix the water injection tubes 400. The friction of the rubber band 420 surface can also limit the magnet 440 to prevent it from sliding on the rubber band 420. The rubber band 420 can be cut as needed. The iron wire 421 inside the rubber band 420 is relatively thin and can be cut with ordinary scissors.

[0030] Example 2

[0031] Based on Example 1, adhesive tape 422 is provided on the rubber belt 420 to facilitate user operation.

[0032] like Figure 4 As shown, in this embodiment, an adhesive tape 422 is fixedly bonded to one side of the rubber strip 420.

[0033] In practice, the adhesive tape 422 is a double-sided tape. When using it, the release paper of the adhesive tape 422 can be directly peeled off, and then the adhesive tape 422 can be adhered to the appropriate position. The rubber tape 420 can reduce the contamination of the adhesive tape 422 by substances such as blood and water, thereby reducing the adhesion effect of the adhesive tape 422.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
