Currently, ileus treatment devices include a catheter and a guidewire that is coupled to the catheter. The guide wire can penetrate through two ends of the catheter when entering the catheter. The intestinal canal dredging operation of patient obstruction is that one end of the guide wire and one end of the guide pipe enter the pylorus of the patient through the nasal cavity of the patient, at the moment, the patient is irradiated by X-ray to display a real-time picture in the patient body to an operator, and the operator controls one end of the guide wire to penetrate the pylorus of the patient through controlling the other end of the guide wire at the other end of the guide pipe according to the real-time picture, so that the patient enters the intestinal canal to perform obstruction treatment. The inventor has accumulated experience of long-term operation and found that although the mode can achieve the purpose of operation, the length of the guide wire is more than 3 meters, and the guide wire is quite inconvenient to operate by operators, and passes through the pylorus and can only be carried out by the operator. Furthermore, this method also results in a long operation time and a patient being irradiated with X-rays for a long time and being exposed to a large amount of radiation, which is disadvantageous for the physical health of the patient. Based on the operation mode, the inventor has invented a intestinal obstruction therapeutic device through a great deal of practical research. This intestinal obstruction treatment device penetrates in the pipe through the seal wire being close to the one end of pipe for the operating distance of seal wire is shortened by very big, and then makes operating personnel just can operate the seal wire and pass the pylorus in the short time, so realized shortening operation time very big, the radial volume that the patient received also reduces extremely.

Referring to fig. 1, an embodiment of the present invention provides a ileus treatment device 100. In the practice of the present invention, the ileus treatment device 100 may be used to perform ileus surgical treatment on a patient. Specifically, the ileus treatment device 100 includes: ileus catheter 110, first guidewire 120, and second guidewire 130.

Ileus catheter 110 may be a hollow tubular structure made of a flexible material. In this embodiment, the flexible material of the ileus catheter 110 may be plastic, rubber or polymer composite, which can ensure the softness and bending resistance of the ileus catheter 110 without damaging the intestinal tract. Further, the specific shape of the cross-section of the tubular structure of ileus catheter 110 may be: circular, rectangular, triangular, irregular polygonal or regular polygonal, etc. To ensure that ileus catheter 110 is convenient for use in practice, the particular shape of the cross section of ileus catheter 110 may alternatively be circular, but is not intended to be limiting of the present embodiment. In addition, the diameter of the cross section of ileus catheter 110 may be adjusted according to the actual application, and the present embodiment is not particularly limited. The length of the ileus catheter 110 is required to meet the requirement of the operation, and further may be 3 meters to 4 meters, but the specific length is not limited to this embodiment, and may be adjusted according to the actual requirement.

Referring to fig. 1 and 2, the hollow tubular structure of ileus conduit 110 enables opposite ends, when ileus conduit 110 is placed on a horizontal plane with the line connecting the ends perpendicular to the horizontal plane, the end of ileus conduit 110 in contact with the horizontal plane is first end 111 of ileus conduit 110, and the other end of ileus conduit 110, which is far from the horizontal plane in this placement, is second end 112 of ileus conduit 110. Both the first end 111 and the second end 112 of the ileus conduit 110 are open, i.e. the first end 111 of the ileus conduit 110 has a first opening 113 and the second end 112 of the ileus conduit 110 has a second opening 114, from the first opening 113 of the first end 111 into the ileus conduit 110 and from the second opening 114 of the second end 112 out of the ileus conduit 110. In this embodiment, the shapes of the first opening 113 and the second opening 114 may be: circular, rectangular, triangular, irregular polygonal or regular polygonal, etc. To ensure that ileus catheter 110 is convenient for use in practice, the specific shape of first opening 113 and second opening 114 may alternatively be circular, but is not limiting to this embodiment. In addition, the diameter of the first opening 113 may be the same as the diameter of the second opening 114, and the diameter of the first opening 113 and the diameter of the second opening 114 are not specifically limited in this embodiment, which ensures that the diameter of the first opening 113 can enable the first guide wire 120 to pass through the first opening 113.

To facilitate entry of first guidewire 120 into ileus catheter 110 on ileus catheter 110 near first end 111, ileus catheter 110 is provided with a through hole 115 near first end 111 so that first guidewire 120 can pass through hole 115 into ileus catheter 110. Further, to facilitate the insertion of first guidewire 120 into ileus catheter 110 through throughbore 115 during actual use, the number of throughbores 115 may be multiple, such as 3 throughbores 115. The shape of each of the plurality of through holes 115 may be: circular, rectangular, triangular, irregular polygonal or regular polygonal, etc. To ensure that ileus catheter 110 is convenient for use in practice, each of through holes 115 may alternatively be circular in specific shape, but is not intended to be limiting of the present embodiment. In addition, the diameter of each through hole 115 is the same as the diameter of the other through holes 115, but the diameter of each through hole 115 is not particularly limited in this embodiment, and it is sufficient to ensure that the diameter of each through hole 115 is larger than the diameter of the first guide wire 120, so that the first guide wire 120 can pass through each through hole 115. The plurality of through holes 115 are arranged in parallel near the first end 111 of the ileus catheter 110, and the distance between each through hole 115 and the adjacent through hole 115 in the plurality of through holes 115 can be adjusted according to practical use, and the distance value is not particularly limited in this embodiment. Further, the first guidewire 120 may be advanced into the ileus catheter 110 from any one of the plurality of through holes 115, 115.

As shown in fig. 1 and 2, the first guide wire 120 may be a flexible steel wire made of a stainless steel material. And the first guide wire 120 is a flexible steel wire such that the cross section of the first guide wire 120 may be: circular, rectangular, triangular, irregular polygonal or regular polygonal, etc. To ensure that the first guide wire 120 is convenient for practical use, the specific shape of the cross section of the first guide wire 120 may alternatively be circular, but is not limited to this embodiment. In addition, the diameter of the cross-section of first guidewire 120 should be smaller than the diameter of first opening 113 and the diameter of each through-hole 115 to ensure that first guidewire 120 is able to enter into ileus catheter 110 or exit from ileus catheter 110, but the particular value of the diameter of the cross-section of first guidewire 120 is not particularly limited in this embodiment. The length of the first guide wire 120 may be slightly smaller than the length of the ileus catheter 110, i.e. the total length of the first guide wire 120 may be 2 meters to 3 meters, but the specific length is not limited to this embodiment, and may be adjusted within a range according to practical use requirements.

In this embodiment, the elongated structure of the first guide wire 120 enables the first guide wire 120 to have opposite ends, which are the third end 121 and the fourth end 122 of the first guide wire 120, respectively. The first guide wire 120 enters the ileus catheter 110 near the first end 111 on the ileus catheter 110, that is, the third end 121 of the first guide wire 120 enters the ileus catheter 110 through any one of the through holes 115. After third end 121 enters ileus conduit 110, third end 121 can be moved in a direction toward first opening 113 proximate first end 111 of ileus conduit 110 so that third end 121 can pass out of ileus conduit 110 from first opening 113 at first end 111.

To allow an operator to more easily control first guidewire 120, when third end 121 of first guidewire 120 is threaded out of ileus catheter 110 from first opening 113 of first end 111, the length of first guidewire 120 within ileus catheter 110 is an inner length value, and the ratio of the inner length value to the total length value of first guidewire 120 is 5% to 15%. Based on this ratio, so that a majority of first guidewire 120 is outside of ileus conduit 110, third end 121 of first guidewire 120 may enter the patient from the nasal cavity of the patient prior to ileus conduit 110. When the third end 121 enters the patient and needs to pass through the pylorus, the length of the first guide wire 120 in the patient is only the length from the nasal cavity of the patient to the pylorus, so that when the operator operates the first guide wire 120 at the nasal cavity of the patient, the operating distance is greatly shortened, and the operator can more conveniently and rapidly operate the first guide wire 120 to pass through the pylorus in a short time.

In practical use, the fourth end 122 may be inserted into the ileus conduit 110 through the through hole 115, and the third end 121 is taken as an example in this embodiment, which is not limited to this embodiment.

As an embodiment, in order to facilitate that the operator can clearly know the image photographed by the X-ray by the corresponding operator controlled state of the first guide wire 120 when controlling the first guide wire 120, the third end 121 of the first guide wire 120 further has a hook 123. The hook 123 presents a fish hook shape, but the hook tip of the hook 123 is smooth to avoid the hook 123 from scratching the patient. The hook 123 is used for the first guide wire 120 to be controlled by an operator when the hook 123 exhibits the controlled state of the first guide wire 120. For example, the operator rotates the first guide wire 120, and the hook 123 accordingly displays a corresponding rotation in the screen. Since the hook 123 can show the controlled state of the first guide wire 120, the operator can more clearly know and adjust the control of the first guide wire 120, so that the time for the first guide wire 120 to enter the pylorus is further shortened.

As also shown in fig. 1 and 2, the second guide wire 130 may be a flexible steel wire made of a stainless steel material. And the second guide wire 130 is a flexible steel wire such that the cross section of the second guide wire 130 may be: circular, rectangular, triangular, irregular polygonal or regular polygonal, etc. To ensure that the second guide wire 130 is convenient for practical use, the specific shape of the cross section of the second guide wire 130 may be circular, but is not limited to this embodiment. In addition, the diameter of the cross-section of second guidewire 130 should be smaller than the diameter of first opening 113 and the diameter of second opening 114 to ensure that second guidewire 130 can be positioned within ileus catheter 110, but the particular value of the diameter of the cross-section of second guidewire 130 is not particularly limited in this embodiment. The length of the second guide wire 130 may be matched with the length of the ileus catheter 110, that is, the total length of the second guide wire 130 may be 3 meters to 4 meters, but the specific length is not limited in this embodiment, and may be adjusted within a range according to practical use requirements.

In this embodiment, the elongated structure of the second guide wire 130 enables the second guide wire 130 to have opposite ends, which are the fifth end 131 and the sixth end 132 of the second guide wire 130, respectively. The fifth end 131 or sixth end 132 of the second guidewire 130 may enter the ileus catheter 110 through the first opening 113 of the first end 111 of the ileus catheter 110 and move in the direction of the second opening 114 of the second end 112 of the ileus catheter 110 to dispose the second guidewire 130 into the ileus catheter 110. Of course, either fifth end 131 or sixth end 132 of second guidewire 130 may enter ileus catheter 110 through second opening 114 of second end 112 of ileus catheter 110 and move in the direction of first opening 113 of first end 111 of ileus catheter 110, also causing second guidewire 130 to be disposed within ileus catheter 110.

After the second guidewire 130 is disposed within ileus catheter 110, it may be used to support ileus catheter 110. The use of the second guidewire 130 allows for sharing of the thrust force experienced by the ileus catheter 110 due to the supporting effect of the second guidewire 130. When the pushing force is respectively applied to the second guide wire 130 and the intestinal obstruction catheter 110, the supporting action of the second guide wire 130 enables the intestinal obstruction catheter 110 to move in the intestinal tract more conveniently and rapidly, so that the operation time is further shortened.

It will be appreciated that since the second guidewire 130 is required to form a support for the ileus catheter 110, the stiffness of the second guidewire 130 should be greater than the stiffness of the first guidewire 120.

Referring to fig. 3 and 4, the present invention provides an apparatus 100 for treating intestinal obstruction according to the following working principles:

in a procedure requiring ileus dredging of a patient with ileus, an operator first selects a through hole 115 from a plurality of through holes 115 and passes a third end 121 through the through hole 115 into the ileus conduit 110, and then passes the third end 121 out of the first opening 113 of the first end 111 of the ileus conduit 110. At this point, the operator manipulates the third end 121 of the first guidewire 120 from the nasal cavity of the patient prior to the entry of the ileus catheter 110 into the patient. When the third end 121 enters the stomach of the patient, the operator controls the first guide wire 120 at the nasal cavity of the patient based on the image shot by the X-ray, the distance from the nasal cavity of the patient to the pylorus of the patient makes the control of the operator very effective, and then the third end 121 of the first guide wire 120 can pass through the pylorus and enter the duodenum of the patient under the control of the time period. At this time, the ileus catheter 110 placed outside the patient and the second guide wire 130 placed inside the ileus catheter 110 can be introduced into the patient from the nasal cavity of the patient, and the ileus catheter 110 can rapidly pass through the pylorus into the duodenum under the guiding action of the first guide wire 120 and the supporting action of the second guide wire 130. In this state, the most difficult procedure has been completed, and the operator can perform the subsequent procedure of the operation conveniently, completing the ileus operation on the patient.

In summary, the embodiments of the present invention provide a device for treating ileus. Comprising the following steps: a first guidewire and a ileus catheter. The ileus catheter has a first end and a second end, the first end being open. The first guidewire has a third end and a fourth end, the third end entering the ileus catheter over the ileus catheter proximate the first end such that the third end is capable of passing out of the ileus catheter from the first end.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
