Description

Technical Field

[0001] The invention relates to the technical field of endoscopic imaging catheters, and in particular to an electronic imaging catheter. Background Art

[0002] The imaging catheter for endoscope is a common medical device, which usually includes an operating handle and an insertion part, wherein the insertion part can enter the human body through the human cavity, and the camera module of the insertion part can observe the internal tissues of the human body. During the specific operation, the bending action can be achieved by controlling the operating handle to pull the curved section at the front end of the insertion part through the traction wire, thereby changing the direction of the front end of the insertion part, helping the doctor to determine the location of the lesion in the patient's body and the tissue structure of the lesion. For tissue lesions, it is necessary to extend the external treatment device through the instrument built into the insertion part to the lesion for sampling or drug treatment, and at the same time, it is necessary to suction the blood or secretions produced by the operation.

[0003] There are several problems with existing imaging catheters:

[0004] 1. Most of the existing suction connectors are separated and externally installed. When suction is needed, it needs to be manually inserted into the suction outlet for suction. After long-term use, the seal failure may occur at the connection between the suction connector and the suction outlet, resulting in leakage of the effusion extracted by the suction valve, which causes the effusion to be contaminated and is more troublesome for doctors to operate.

[0005] 2. The operating handle is the handheld part, and the operating buttons of the image processor are separated from the operating handle. When doctors are looking for the lesion location during surgery or taking photos, videos, or freeze contrast as teaching materials, they often need to operate the operating buttons of the image processor to achieve the corresponding functions, which requires the cooperation of other doctors, which is very inconvenient;

[0006] 3. Currently, the insertion part of the imaging catheter is usually connected to the operating handle by a data cable, which is inconvenient to carry;

[0007] 4. Due to the deviation in precision, it is difficult to achieve consistent tightness of the traction wire during installation. During the use of the imaging catheter, the traction wire may be over-tightened or over-slackened, resulting in reduced adjustment accuracy of the bending section of the insertion part, making it difficult to achieve the expected bending effect, which will affect the image field of the imaging catheter. Summary of the invention

[0008] In order to overcome at least one defect of the above-mentioned prior art, the present invention provides an electronic imaging catheter. By providing multiple rows of linearly arranged steel wire slots, when the steel wire length precision deviation is inconsistent, it can be fixed by selecting a suitable steel wire slot, so that the steel wires with different precision deviations can achieve consistent tension, and the fixing effect is achieved by the rotating groove and the rotating boss, and the function button is integrated into the imaging catheter handle, which is more convenient to operate.

[0009] The technical solution adopted by the present invention to solve the problem is:

The suction connector is provided with a suction button, and the suction button is used to control the opening and closing of the suction cavity.

[0013] By adopting the above scheme, the accumulated fluid, secretions and removed diseased tissue of the diseased tissue can be sucked out when the suction button is pressed. When the suction button is released, the suction cavity between the suction inlet and the suction outlet is closed, which plays a good sealing role.

[0014] Furthermore, the attraction button is made of elastic material.

[0015] By adopting the above solution, the elastic material itself has elasticity, has low requirements on the manufacturing process, has lower costs, and is more practical.

[0016] Furthermore, a wire groove is provided on one side of the curved shaft, and a wire guide groove is provided in the accommodating cavity, so that the steel wire passes through the wire groove and the wire guide groove and is connected to the other end of the imaging catheter insertion portion.

[0018] Furthermore, an anti-slip handle is provided on the outer surface of the connecting joint.

[0019] By adopting the above solution, the friction is increased by the anti-slip handle, which prevents the doctor's hand from slipping when twisting, and makes it more convenient to rotate and bear force.

[0020] Furthermore, a data connection interface is provided on the imaging catheter handle.

[0021] By adopting the above solution, it is convenient to realize data connection through the data connection interface.

[0025] By adopting the above scheme, the connection is made through the suction catheter, so that the accumulated fluid and secretions of the diseased tissue and the removed diseased tissue can be easily sucked out.

[0026] Furthermore, the length of the rotating boss is one quarter of a circular arc, and the length of the rotating groove is one half of a circular arc.

[0027] By adopting the above solution, a larger angle of rotation can be achieved by increasing the difference between the rotating groove and the rotating boss, which reduces the doctor's need to search for the field of vision by twisting his arms or body, making it easier and more convenient.

Therefore, they cannot be understood as limiting the present invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 The present invention discloses an electronic imaging catheter: comprising an imaging catheter handle 1 and an imaging catheter insertion part 2, wherein one end of the imaging catheter handle 1 is provided with a fixed boss 11 and a rotating boss 12, and the interior of the imaging catheter handle 1 is hollow to form a receiving chamber 13; the imaging catheter insertion part 2 has an axially through cavity 21, and one end of the imaging catheter insertion part 2 is connected with a connecting joint 3, and the two ends of the connecting joint 3 are open and the interior is hollow to form a through cavity, and a fixed groove 31 and a rotating groove 32 are provided inside the through cavity, wherein the fixed boss 11 is assembled and connected with the fixed groove 31, and the rotating boss 12 is assembled and connected with the rotating groove 32. The fixing effect is achieved by clamping the rotating groove 32 with the rotating boss 12, and it is convenient to carry.

[0042] Specifically, the through cavity is hollow so as to be compatible with the end of the imaging catheter handle 1, and the connection between the connecting joint 3 and the imaging catheter insertion part 2 is an integrally formed connection, which has a stable structure. Specifically, the length of the rotating boss 12 is a quarter of a circle, and the length of the rotating groove 32 is a half of a circle. By increasing the difference between the rotating groove 32 and the rotating boss 12, a larger angle of rotation can be achieved, which reduces the doctor's need to twist his arm or body to find the field of vision, making it easier and more convenient.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, a bending shaft 4 is provided inside the accommodating cavity 13, and a plurality of rows of linearly arranged steel wire slots 41 are provided on the bending shaft 4. A steel wire 42 is connected to the steel wire slot 41, and the other end of the steel wire 42 is connected to the other end of the imaging catheter insertion part 2. In actual use, since the length precision deviation of the steel wire 42 is inconsistent, it can be fixed by the plurality of rows of linearly arranged steel wire slots 41, so that the steel wires 42 with different precision deviations have consistent tension. At the same time, a steel wire slot 44 is provided on one side of the bending shaft 4, and a steel wire guide slot 45 is provided in the accommodating cavity 13, so that the steel wire 42 passes through the steel wire slot 44 and the steel wire guide slot 45 and is connected to the other end of the imaging catheter insertion part 2. The steel wire slot 44 and the steel wire guide slot 45 can guide the steel wire 42 to be pulled into the imaging catheter insertion part 2, and the steel wire guide slot 45 can prevent the steel wire 42 from rubbing against other lines inside the accommodating cavity 13 when being pulled and bent, resulting in wear and breakage.

[0044] The bending shaft 4 extends to the outside of the imaging catheter handle 1 and is connected to a push rod 43 . The push rod 43 controls the rotation of the bending shaft 4 and drives the steel wire 42 to bend so as to change the bending angle of the other end of the imaging catheter insertion portion 2 .

[0045] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a circuit board is arranged inside the accommodating cavity 13, a button hole is provided on the imaging catheter handle 1, a function button 14 is arranged in the button hole, the function button 14 is electrically connected to the circuit board, and a data connection interface 16 is provided on the imaging catheter handle 1, so as to facilitate data connection through the data connection interface 16. And this design integrates the function button 14 into the imaging catheter handle 1, which is more convenient to operate. It should be noted that the function button 14 is set to two, and the two function buttons 14 are respectively a photo taking button and a video recording button, so that the imaging catheter handle 1 can realize the photo taking and video recording functions by directly pressing the buttons, which is convenient and quick.

[0046] The outer surface of the connecting joint 3 is provided with an anti-slip handle 33, which increases the friction force to prevent the doctor's hand from slipping when twisting, making it more convenient to rotate and bear force. It should be noted that the connecting joint 3 is conical.

[0047] By rotating the anti-slip handle 33, the imaging catheter insertion part 2 can be driven to rotate together with it, and a rotation angle of 90 degrees can be achieved. If the rotation angle needs to be increased, a larger angle of rotation can be achieved by increasing the difference between the length of the rotation groove 32 of the connecting joint 3 and the length of the rotation boss 12 of the imaging catheter handle 1. This reduces the need for doctors to twist their arms or bodies to find the field of view, making it easier and more convenient.

[0048] See also Figure 1 , Figure 2 and Figure 3 As shown, the imaging catheter handle 1 is provided with a suction connector 15, and the suction connector 15 has a suction inlet and a suction outlet 151, and a suction cavity 21 is formed between the suction inlet and the suction outlet 151. The suction connector 15 is provided with a suction button 152, and the suction button 152 is used to control the opening and closing of the suction cavity 21. When the suction button 152 is pressed, the accumulated fluid, secretions and removed diseased tissue of the diseased tissue can be sucked out. When the suction button 152 is released, the suction cavity 21 between the suction inlet and the suction outlet 151 is closed, which plays a good sealing role.

[0049] The accommodating cavity 13 is also provided with an instrument cavity guide groove 131, and a cavity interface 132 is provided in the instrument cavity guide groove 131. The cavity interface 132 extends to the outside of the imaging catheter handle 1 and is provided with an interface cover 133 that can cover the cavity interface 132, so that the cavity interface 132 can be conveniently covered by the interface cover 133 to play a sealing role. A suction catheter 153 is connected between the suction inlet and the cavity interface 132 and located in the accommodating cavity 13, and is connected through the suction catheter 153 to facilitate the suction of the effusion and secretions of the diseased tissue and the removed diseased tissue.

[0050] The suction outlet 151 of the suction connector 15 can be connected to a negative pressure suction device for suction. Specifically, the suction button 152 is made of an elastic material. In this embodiment, the elastic material can be rubber. The elastic material itself has elasticity, has low requirements for the manufacturing process, has lower costs, and is more practical. When the suction button 152 is pressed, the suction cavity 21 between the suction inlet and the suction outlet 151 is opened, and the effusion, secretions, and excised lesion tissue of the diseased tissue can be sucked out; when the suction button 152 is released, the suction cavity 21 between the suction inlet and the suction outlet 151 is closed, which plays a sealing role.
