Description

Radial artery puncture interventional therapy hepatic curvature catheter

Technical Field

The utility model relates to a bent pipe of liver, concretely relates to curved pipe of treatment liver is intervene in radial artery puncture.

Background

‌ liver interventional therapy is conducted by introducing special catheter and guide wire into human body under the guidance of medical imaging equipment to diagnose and treat partial liver diseases; interventional therapy adopts the wicresoft treatment mode, the femoral artery department at thigh root opens a puncture wound of 2 ~ 3mm, the pipe is through femoral artery, abdominal aorta gets into the hepatic artery and treats the liver, for the operation treatment mode, interventional therapy has and need not the operation, the fast advantage is resumeed to the postoperative, even if interventional therapy, patient's postoperative thigh root also needs the pressurization to wrap, wrap the position at thigh root owing to the pressurization, consequently, the postoperative patient can only lie flat bed, to the patient diet this moment and all have inconvenience like the lavatory.

Disclosure of Invention

Problem to above-mentioned prior art exists, the utility model provides a radial artery puncture intervenes treatment liver curved catheter, entering hepatic artery that can be accurate quick intervenes the treatment, and intervenes the treatment back, and the patient need not the bed of lying.

In order to achieve the above object, the utility model provides a following technical scheme: a catheter for radial artery puncture interventional therapy of hepatic curvature is integrally formed and comprises a catheter main body, a turning section, a reverse bending section and a hepatic artery entrance section; the steering section is positioned in the middle of the catheter main body, the reverse bending section is positioned at the front end part of the catheter main body, and the hepatic artery inlet section is positioned at the front end part of the reverse bending section; the reverse bending section and the catheter main body are bent by 180 degrees, and the hepatic artery entrance section is obliquely bent upwards relative to the plane where the catheter main body and the reverse bending section are located together.

Furthermore, the steering section is made of polyurethane, and has the advantages of strong ageing resistance, good tissue compatibility, no toxicity, extremely smooth surface and small encrusting tendency.

Furthermore, the rear end part of the catheter main body is provided with a pushing holding piece.

Furthermore, the propelling holding piece comprises a handle and a baffle ring, the handle sleeve is embedded on the outer side of the rear end part of the catheter main body, and the baffle ring is arranged at the top end of the handle.

Compared with the prior art, the utility model has the advantages that the puncture position is at the radial artery of the hand of the patient when in use, the hand of the patient can be packed by pressurizing after the operation, the patient does not need to lie down after the operation, and the influence on the postoperative activity of the patient is small; the catheter is turned from the radial artery to enter the hepatic artery, the turning section has better flexibility, and the burden on the blood vessel at the turning position is lighter; the reverse bending section and the hepatic artery entrance section are arranged, so that the catheter can quickly and accurately enter the hepatic artery entrance.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a pushing grip;

in the figure: 0. the device comprises a catheter 1, a catheter main body 2, a steering section 3, a reverse bending section 4, a hepatic artery inlet section 5, a pushing holding piece 51, a handle 52 and a retaining ring.

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: the catheter 0 is integrally formed and consists of a catheter main body 1, a turning section 2, a reverse bending section 3 and a hepatic artery inlet section 4; the steering section 2 is positioned in the middle of the catheter main body 1, the reverse bending section 3 is positioned at the front end part of the catheter main body 1, and the hepatic artery inlet section 4 is positioned at the front end part of the reverse bending section 3; the reverse bending section 3 and the catheter main body 1 are bent by 180 degrees, and the hepatic artery entrance section 4 is obliquely bent upwards relative to the plane where the catheter main body 1 and the reverse bending section 3 are located together.

When the catheter is used, the catheter penetrates into a human body through a radial artery, the catheter 0 firstly travels upwards along the radial artery and then downwards enters a hepatic artery at the shoulder part of a patient, the setting position of the steering section 2 is the position of the catheter 0 at the shoulder part of the patient, the steering section 2 is made of polyurethane, the flexibility is good, and the burden on a blood vessel at the steering part is light.

Hepatic artery entrance 4 and hepatic artery entry are in the equidirectional, pipe 0 can get into in the hepatic artery easily, hepatic artery entrance 4 is located pipe main part 1 and the reverse one side of bending section 3 simultaneously, 4 planes and the crooked direction in hepatic artery entrance are pipe main part 1 promptly, the planar contained angle in reverse bending section 3 places is 90 degrees, pipe 0 gets into behind the vascular artery like this, need not set up the development mark, just can judge the opening direction, make 0 openings of pipe aim at the hepatic artery entry that can be accurate, improve the operation degree of accuracy, save the operating time.

Considering that the catheter 0 is inconvenient to hold due to a small diameter, in order to facilitate the puncturing operation, the pushing grip 5 is arranged at the rear end of the catheter main body 1, as shown in fig. 2, the pushing grip 5 comprises a handle 51 and a baffle ring 52, the handle 51 is sleeved on the outer side of the rear end of the catheter main body 1, the baffle ring 52 is arranged at the top end of the handle 51, during the puncturing operation, a doctor can hold the handle 51 to push the catheter 0, and the baffle ring 52 stops the doctor's hand to prevent the hand from slipping off during the pushing operation.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
