[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0029] Please see Figures 1 to 5 This is the first embodiment of the present invention. This embodiment provides an integrated hemostasis device for electric rotary cutting and dynamic suction for emergency gastrointestinal endoscopy, including: device shell 1, control terminal 2 is embedded in the outer wall of device shell 1, and cable 3 extends out from one side of control terminal 2 on the outer wall of device shell 1, mounting shell 4 is fixedly installed at the bottom of device shell 1, and gastroscope tube shell 5 extends out from the top of device shell 1, and processing mechanism 6 is provided inside the gastroscope tube shell 5.

[0030] The processing mechanism 6 includes a working tube 601, which extends out of the top of the endoscope tube shell 5. A sheath 602 extends out of the working tube 601. A fixing block 603 is fixedly installed on the outer wall of one end of the sheath 602 that enters the working tube 601. A miniature brushless motor 604 is embedded inside the sheath 602. A flexible coupling 605 is fixedly installed on the power output end of the miniature brushless motor 604.

[0031] The flow channel 7 is connected to the absorption port 802 through the through port 804, and the flow channel 7 is connected to the collection cylinder 806 through the high-frequency pulse suction device 801.

[0032] Specifically, a rotating guide wire 606 is fixedly installed at the top of the flexible coupling 605, and a cutting guide wire 607 is fixedly installed at one end of the rotating guide wire 606 that protrudes from the sheath tube 602.

[0033] Furthermore, the rotating guide wire 606 is connected to the micro brushless motor 604 via a flexible coupling 605, which improves the transmission performance, makes the transmission smoother, and ensures stability and low vibration under high-speed rotation. At the same time, the guide wire surface is designed with a micro spiral texture to enhance cutting efficiency and reduce tissue adhesion.

[0034] Specifically, the sheath 602 extends into the interior of the working tube 601 and forms a rotating structure with the rotating guide wire 606.

[0035] Furthermore, the rotating guide wire 606 and the cutting guide wire 607 are made of nickel-titanium alloy (0.5-0.8mm in diameter). The end of the rotating guide wire 606 extends 5-8mm out of the sheath tube 602 to avoid excessive protrusion or excessive size causing discomfort or injury to the human body. It can also conduct electricity and, with the cooperation of electrocoagulation equipment, can perform electrocoagulation to treat bleeding points.

[0036] In use, the device housing 1 is equipped with a light source and other compatible components, and is powered and transmits information via cable 3, thereby connecting with external devices for image display. Except for the working tube 601, the endoscope tube housing 5 is equipped with a camera and other components. This is a conventional technology and will not be described in detail. Inside the working tube 601, a sheath 602 is embedded through a fixing block 603. The miniature brushless motor 604 embedded in the sheath 602 can drive the rotating guide wire 606 and the cutting guide wire 607 to quickly cut the blood clot according to the observation of the endoscope, through a flexible coupling 605. At the same time, it is powered by a conductive slip ring and cable 3 and connected to an external electrocoagulation device. After the cutting is completed, the wound is directly electrocoagulated through the rotating guide wire 606 and the cutting guide wire 607 to perform electrocoagulation hemostasis.

[0037] In summary, the system first connects to the corresponding external device via cable 3, and then controls the miniature brushless motor 604 and the electrocoagulation device via control terminal 2. The miniature brushless motor 604 drives the rotating guidewire 606 to rotate at high speed, achieving mechanized cutting of blood clots. The rotation speed is precisely controlled using a PID algorithm (adjustable from 2000-5000 rpm). Load torque data of the rotating guidewire 606 is collected, and the motor speed and current output are dynamically adjusted to prevent guidewire jamming or overload. During emergency endoscopic hemostasis, this allows for rapid cutting and removal of blood clots, resulting in a clear endoscopic view and better location of the bleeding point. After locating the bleeding point, the rotating guidewire 606 and cutting guidewire 607 can be switched to electrocoagulation. These devices act as electrodes, generating a high-frequency current that instantly vaporizes water and coagulates proteins in the tissue, achieving hemostasis and tissue coagulation. This high-frequency current is typically in the radio frequency range, generally around 300 kHz. At frequencies up to 1 MHz, when the electrodes of the electrocoagulation device come into contact with the tissue, current passes through the tissue, generating heat, causing the water inside the tissue cells to evaporate, leading to cell rupture and protein denaturation, thereby achieving the purpose of hemostasis and tissue coagulation. Example

[0038] Please see Figures 1 to 6 This is the second embodiment of the present invention, which provides an improved design for an integrated hemostasis device for emergency gastrointestinal endoscopy with electric rotary cutting and dynamic suction.

[0039] Specifically, a flow groove 7 is provided between the working tube 601 and the sheath tube 602, and a suction mechanism 8 is provided at the bottom end of the working tube 601.

[0040] Furthermore, a flow channel 7 is formed inside the working tube 601 to allow broken blood clots and tissues to be drawn up and collected by the suction mechanism 8, so as to avoid affecting the field of view of the gastroscopy and the doctor's diagnosis.

[0041] Specifically, the suction mechanism 8 includes a high-frequency pulse suction device 801, which is embedded inside the mounting shell 4, and the top of the working tube 601 is provided with an absorption port 802.

[0042] Furthermore, the high-frequency pulse suction device 801 generates a high-frequency pulse signal through the host to drive the motor or pump to generate a periodically changing negative pressure. This negative pressure can more effectively adsorb broken blood clots and tissues through the absorption port 802, avoiding affecting the doctor's field of vision.

[0043] Specifically, a guide block 803 is fixedly installed on the outer wall of one end of the inner sheath 602 of the working tube 601, and a through hole 804 is opened on one side of the bottom end of the guide block 803.

[0044] Furthermore, the guide block 803 facilitates the flow of blood clots and tissues into the through-hole 804. The reduced through-hole 804 enhances the adsorption force and prevents the adsorption port from being too large, which would affect the suction and prevent sufficient collection.

[0045] Specifically, a blade 805 is fixedly installed on one side of the sheath 602 inside the absorption port 802, and a collection cylinder 806 extends out from the bottom of the mounting shell 4.

[0046] Furthermore, when blood clots or tissue enter the absorption port 802, they are cut by the blade 805 to prevent them from being too large to enter the perforation port 804 for flow, which could lead to blockage, affect the blood clots or tissue, and impair the surgical field of vision.

[0047] In use, with the cooperation of the high-frequency pulse suction device 801, fragmented blood clots and tissues can be extracted through the flow channel 7 and the absorption port 802. When entering the absorption port 802, the blade 805 cuts to avoid blockage. At the same time, it is guided by the guide block 803 to the through port 804, enters the flow channel 7 and is discharged to the collection cylinder 806 for unified collection. The collection cylinder 806 is threadedly connected to the discharge port of the high-frequency pulse suction device 801. After one case of surgery, the shell is cleaned and the collection cylinder 806 is replaced for the next case.

[0048] In summary, the high-frequency pulse suction device 801 can be linked with the processing mechanism 6 to absorb and discharge broken blood clots and tissues during the cutting process, avoiding visual interference caused by broken blood clots and tissues during cutting or electrocoagulation, thus affecting the doctor's treatment and diagnosis. The absorption port 802 is located on one side of the sheath tube 602, which can directly absorb the broken blood vessel tissues during cutting. The blade 805 can further break the tissues during the absorption process to prevent blockage during transport. The tissues are then collected in a collection tube 806 for easy cleaning and replacement later.
