Abstract

The utility model provides a far-end passage catheter, which relates to the medical field and comprises a catheter body and a first guide head, wherein one side of the catheter body is provided with the first guide head, the periphery of the first guide head is provided with a connector, one side of the connector is provided with a second guide head, and the other side of the connector is provided with an elastic band.

Description

Distal access catheter

Technical Field

The utility model relates to the medical field, in particular to a distal access catheter.

Background

The distal end passageway pipe, an intervention surgical instrument, but exclusive use also can use with other intervention instruments, is used for vascular system disease treatment field, and current distal end passageway pipe is as shown in fig. 1, comprises pipe body and guide head, but this technical scheme has the problem that, current distal end passageway pipe's guide head is mostly circular tubular guide head, when guiding through crooked vascular department, the condition that is difficult to turn and pass through probably can appear, leads to the staff to adjust constantly, causes the influence to the treatment.

Disclosure of Invention

The utility model aims to solve the following problems in the prior art: most of the guide heads of the existing distal access catheters are round tubular guide heads, and when the guide heads are guided to a bent blood vessel, the situation that the guide heads are difficult to turn and pass can occur, so that the guide heads need to be continuously adjusted by staff, and the treatment work is influenced.

In order to solve the problems in the prior art, the utility model provides a distal access catheter which comprises a catheter body and a first guide head, wherein the first guide head is arranged on one side of the catheter body, a connector is arranged on the periphery of the first guide head, a second guide head is arranged on one side of the connector, and an elastic band is arranged on the other side of the connector.

Further, the second guide head is in a ball shape, and an opening is formed in one side of the second guide head. The second guide head with the smooth spherical cambered surface can easily pass through the bent blood vessel.

Furthermore, the connector and the second guide head are hollow, and the size specification of the connector is slightly larger than that of the first guide head. The connector and the second guide head are hollow, so that diagnosis or surgical instruments in the catheter body and the first guide head can be conveniently transmitted.

Furthermore, the elastic band is made of elastic rubber, and one side of the elastic band is connected with the inner wall of the connector. The elastic band pulled out of the inner wall of the connector is sleeved on the periphery of the first guide head, and the connector is limited by the elastic band made of elastic rubber materials.

Furthermore, the connector and the second guide head are made of transparent materials. Transparent materials are adopted to facilitate observation by workers.

Further, the catheter body and the first guide head are integrated, and the catheter body and the interior of the first guide head are hollow and communicated. The catheter body and the inner cavity of the first guide head are used for conveying other diagnosis or surgical instruments.

Compared with the prior art, the utility model has the beneficial effects that:

in the use process of the utility model, a worker can align the connector at the other side of the second guide head with the first guide head, buckle the connector into the periphery of the first guide head, then pull out the elastic band on the inner wall of the connector to sleeve the connector at the periphery of the first guide head, limit the connector through the elastic band made of elastic rubber materials, ensure the stability of the connector, when the connector is guided into a blood vessel to pass through a bent blood vessel, the second guide head with a smooth spherical cambered surface can pass through the bent blood vessel more easily, and the design of the second guide head and the connector can increase the overall hardness, thereby avoiding the situations of twisting, winding and the like.

Detailed Description

In order that the manner in which the above recited features, objects and advantages of the present utility model are obtained, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model.

Specific embodiments of the present utility model are described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-3, a distal access catheter is provided, wherein a first guide head 2 is provided on one side of a catheter body 1, a connector 3 is provided on the periphery of the first guide head 2, a second guide head 4 is provided on one side of the connector 3, and an elastic band 5 is provided on the other side of the connector 3.

Description of working principle: during the use, the staff can aim at first guide head 2 with connector 3 of second guide head 4 opposite side to detain connector 3 in first guide head 2 periphery, the elastic band 5 of the inner wall of connector 3 is pulled out closely and overlaps it in first guide head 2 periphery, carry out spacingly to connector 3 through elastic band 5 that elastic rubber material made, guarantee the stability of connector 3, when the guide gets into the vascular through crooked vascular, then comparatively easy through crooked vascular through the second guide head 4 that possess smooth ball-shaped cambered surface, and can increase holistic hardness through the design of second guide head 4 and connector 3, avoid appearing the condition such as distortion winding.

The catheter body 1 is a tube body of a distal access catheter, and is selected according to the need by conventional selection in the prior art.

The first guide head 2 is mainly used for guiding the catheter body 1, and is used for conventional selection in the prior art according to the need.

The connector 3 is mainly used for connecting the first guide head 2 and the second guide head 4, and is made of transparent materials when in use, and the inner wall of the connector is connected with an elastic band 5.

The second guide head 4 is mainly used for assisting the catheter body 1 to advance in a blood vessel, and is in a spherical shape when in use, the inside of the second guide head is hollow, and one side of the second guide head is provided with an outlet.

The elastic band 5 is mainly used for limiting the connector 3, and an elastic band made of elastic rubber material is adopted when the connector 3 is selected.
