Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a hemostatic device for acute gastrointestinal bleeding. Background Art

[0002] As is known, acute gastrointestinal bleeding is a serious medical emergency, usually manifested as symptoms such as hematemesis, melena or intestinal bleeding, which may be caused by various factors, including peptic ulcer, esophageal varices, tumors, infections, etc. Due to the complex structure of the digestive tract and diverse etiologies, rapid and effective hemostatic measures are crucial for saving the patient's life.

[0003] Existing gastrointestinal hemostasis methods usually rely on endoscopic surgery, such as gastroscopy and colonoscopy. These methods can directly observe the bleeding location under the endoscope and stop bleeding by means such as electrocoagulation, injection of hemostatic agents, or clamping the bleeding point. However, this method has several significant problems: (1) Equipment and condition limitations: Due to the complexity of the digestive tract and the concealment of some lesions, doctors may need to spend a lot of time performing endoscopic examinations to determine where the bleeding is located, which may delay treatment in emergency situations. Moreover, not all medical institutions are equipped with high-end endoscopic equipment. Especially in remote areas or emergency situations, the lack of appropriate equipment and professional personnel may prevent patients from receiving endoscopic treatment in a timely manner. In addition, patients with acute gastrointestinal bleeding often require immediate intervention, but the preparation time for endoscopic surgery may not meet this urgent need.

[0004] (2) Patient tolerance issues: For some patients, especially critically ill patients, the elderly or those with other complications, the tolerance to endoscopic examinations is poor and they may not be able to withstand the endoscopic procedures. Summary of the Invention

[0005] (I) Invention Objectives

[0006] In view of this, the objective of the present invention is to provide a hemostatic device for acute gastrointestinal bleeding. Through this device, in the absence of surgical conditions or in emergency situations, for patients with acute gastrointestinal bleeding, without the need for gastroscopy or colonoscopy surgery, the hemostatic capsule can initially stop bleeding at the bleeding location of the patient's digestive tract, creating time and conditions for subsequent surgical preparations.

[0007] (II) Technical Solutions

[0008] To achieve the above technical objective, the present invention provides a hemostatic device for acute gastrointestinal bleeding, which includes a hemostatic capsule. A drug release mechanism is arranged inside the hemostatic capsule, and through the drug release mechanism, hemostatic liquid medicine can be directly released at the bleeding location of the digestive tract.

[0009] The surface of the hemostatic capsule is provided with an external spray hole at the position of the drug release mechanism. The drug release mechanism includes a medicine cylinder fixed inside the hemostatic capsule for storing hemostatic liquid medicine. There is a gap between the medicine cylinder and the outer wall of the hemostatic capsule to form a drug release space. The bottom of the medicine cylinder is communicated with the drug release space through a drug release port. An activatable shutter is arranged inside the drug release space. The surface of the shutter is provided with an internal spray hole. A pushing component is arranged inside the medicine cylinder to extrude and push the hemostatic liquid medicine into the drug release space.

[0010] The shutter can move to a first position and a second position under external constraints. The first position is the drug release position where the internal spray hole on the shutter completely coincides with the external spray hole on the surface of the hemostatic capsule. The second position is the closed position where the internal spray hole on the shutter does not coincide with the external spray hole on the surface of the hemostatic capsule at all.

[0011] As a further description of the above technical solution: An arc-shaped electric push rod is arranged inside the drug release space. The piston rod of the electric push rod is connected to one side of the shutter. Under the push of the electric push rod, the shutter can move to the first position or the second position. It should be noted that: The outer wall of the shutter fits with the inner wall of the hemostatic device, and there is a channel for the hemostatic liquid medicine to flow between the inner wall of the shutter and the inner wall of the drug release space.

[0012] Specifically, in order to have a channel for the hemostatic liquid medicine to flow between the inner wall of the shutter and the inner wall of the drug release space, limiting blocks are arranged at the four corner positions of the inner wall of the shutter. The inner wall of the drug release space is provided with limiting sliding grooves adapted to the limiting blocks at the positions of the limiting blocks. The limiting blocks are slidably assembled in the limiting sliding grooves. When the shutter moves, the limiting blocks slide in the limiting sliding grooves. This can not only ensure the stable movement of the shutter but also form a channel for the hemostatic liquid medicine to flow between the inner wall of the shutter and the inner wall of the drug release space under the abutting action of the limiting blocks.

[0013] As a further description of the above technical solution: The pushing component includes a medicine pressing plate and a cylinder. Among them, the cylinder is installed above the medicine cylinder. The medicine pressing plate is movably assembled inside the medicine cylinder. The piston rod of the cylinder extends into the medicine cylinder and is connected to the medicine pressing plate. Therefore, when the cylinder operates and pushes the medicine pressing plate to move downward, the liquid medicine inside the medicine cylinder is extruded, injected into the drug release space through the drug release port, and then ejected to the gastrointestinal bleeding position of the patient with a certain kinetic energy to achieve the effect of inhibiting bleeding.

[0014] As a further description of the above technical solution: A plurality of partition edges are axially arranged in the drug release space. The drug release space is partitioned into a plurality of independent regions by the plurality of partition edges. A drug release port communicating with the inside of the cartridge is correspondingly provided at the bottom of each region. An external spray hole is provided on the hemostatic capsule corresponding to each region. An independent shutter and an electric push rod for controlling the movement of the shutter are arranged in each region. Based on this, when the hemostatic capsule moves to the bleeding position, only the shutter in the drug release space corresponding to the angle of the bleeding position moves for precise drug release.

[0015] As a further description of the above technical solution: The hemostatic capsule includes a housing, a transparent front cover provided at the front end of the housing and having a hemispherical structure, and a tail cover detachably installed at the rear end of the housing and having a hemispherical structure, so that the discomfort of the hemostatic device moving in the patient's digestive tract can be reduced.

[0016] As a further description of the above technical solution: A carrier plate is provided inside the front end of the hemostatic capsule. A plurality of lamp beads are annularly and arrayedly distributed at the edge of the carrier plate. A camera is installed in the middle of the carrier plate. The camera can collect images of the inside of the patient's digestive tract through the transparent front cover and then wirelessly transmit them to an external terminal. The doctor can view and understand the situation of the patient's digestive tract through the terminal. After reaching the bleeding position, the drug release mechanism is remotely and wirelessly controlled to release the drug.

[0017] As a further description of the above technical solution: A sampling mechanism is further provided inside the hemostatic capsule. Tissue samples can be extracted at the diseased position of the patient's digestive tract through the sampling mechanism. The sampling mechanism includes:

[0018] A tissue extraction window opened on the hemostatic capsule;

[0019] A storage bin provided inside the hemostatic capsule, and the storage bin is located inside the tissue extraction window;

[0020] A cutter provided inside the storage bin for cutting and extracting tissue, and the cutter is attached to the inner wall of the hemostatic capsule at the tissue extraction window;

[0021] And a cutter control assembly, which is provided inside the hemostatic capsule and is used to control the movement of the cutter so that it can close the tissue extraction window or cut and extract the tissue entering the tissue extraction window.

[0022] As a further description of the above technical solution: The cutter control assembly includes:

[0023] A fixing piece fixed to the outer wall of the storage bin;

[0024] A turntable rotatably installed on the fixing piece through a rotating shaft, and the axis of the turntable coincides with the midline of the hemostatic capsule;

[0025] A motor is fixed to one side of the fixed piece, and the output shaft of the motor is connected to the turntable;

[0026] A connecting rod has one end fixed to the edge of the turntable and the other end connected to the middle of the cutter. Based on this, when the motor operates, it can drive the turntable to rotate, and through the linkage of the connecting rod, the cutter can move along the inner wall of the hemostatic capsule, realizing the extraction of digestive tract lesion tissues or the closure of the tissue extraction window.

[0027] As a further description of the above technical solution: on both sides of the tissue extraction window on the inner wall of the hemostatic capsule, a front sleeve and a rear sleeve are respectively arranged. Among them, a cavity is arranged in both the front sleeve and the rear sleeve. The cutter is slidably assembled in the cavity of the rear sleeve. The cutter can move along the inner wall of the hemostatic capsule under the control of the cutter control component, so that the front end of the cutter is inserted into the cavity in the front sleeve, realizing tissue cutting extraction and the closure of the tissue extraction window.

[0028] As a further description of the above technical solution: a power supply is arranged inside the hemostatic capsule.

[0029] In the above technical solution, a hemostatic device for acute digestive tract bleeding provided by the present invention enables a patient to swallow the hemostatic capsule for a patient with acute digestive tract bleeding in the absence of surgical conditions or in an emergency. When the hemostatic capsule reaches the bleeding position in the patient's body, a hemostatic liquid medicine is released to the bleeding position through a medicine releasing mechanism, quickly and temporarily inhibiting digestive tract bleeding, creating time and conditions for surgical preparation. And through the structural design of the medicine releasing mechanism, when the hemostatic capsule releases the hemostatic liquid medicine, the hemostatic liquid medicine can accurately and with a certain kinetic energy be ejected to the digestive tract bleeding position of the patient, realizing the effect of efficiently and rapidly inhibiting bleeding. At the same time, this capsule - shaped hemostatic device is not prone to problems of patient tolerance. Description of the Drawings

[0039] The following description is essentially exemplary only and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. In a specific part of a specific drawing, the relevant details or structures of the embodiments of the present disclosure may be illustrated in an exaggerated manner.

[0040] Embodiment 1

[0041] As Figures 1 - 7 shown: This embodiment provides a technical solution: A hemostatic device for acute gastrointestinal bleeding, including a hemostatic capsule 1, and a drug release mechanism 3 is arranged inside the hemostatic capsule 1. Through the drug release mechanism 3, hemostatic liquid medicine can be directly released to the gastrointestinal bleeding position;

[0042] On the surface of the hemostatic capsule 1 at the position of the drug release mechanism 3, an external spray hole 101 is provided. The drug release mechanism 3 includes a cartridge 30 fixed inside the hemostatic capsule 1 for storing hemostatic liquid medicine. There is a gap between the cartridge 30 and the outer wall of the hemostatic capsule 1 to form a drug release space 300. The bottom of the cartridge 30 is connected to the drug release space 300 through a drug release port 302. Inside the drug release space 300, a movable shutter 33 is provided. An internal spray hole 34 is formed on the surface of the shutter 33. Inside the cartridge 30, a pushing component is provided that can squeeze and push the hemostatic liquid medicine to make it enter the drug release space 300;

[0043] The shutter 33 can move to a first position and a second position under external constraints. The first position is the drug release position where the internal spray hole 34 on the shutter 33 completely coincides with the external spray hole 101 on the surface of the hemostatic capsule 1. The second position is the closed position where the internal spray hole 34 on the shutter 33 completely does not coincide with the external spray hole 101 on the surface of the hemostatic capsule 1.

[0044] Working principle: When the hemostatic capsule 1 is in use, first, the cartridge 30 stores hemostatic liquid medicine. At this time, the shutter 33 is in the second position. Since the internal spray hole 34 on the shutter 33 completely does not coincide with the external spray hole 101 on the surface of the hemostatic capsule 1, the inside of the cartridge 30 is isolated from the outside of the hemostatic capsule 1, and the hemostatic liquid medicine will not be released. When the hemostatic capsule 1 moves to the bleeding position in the patient's body, the shutter 33 moves to the first position. At this time, the internal spray hole 34 on the shutter 33 completely coincides with the external spray hole 101 on the surface of the hemostatic capsule 1. The inside of the cartridge 30 is communicated with the outside of the hemostatic capsule 1 through the drug release port 302, the drug release space 300, the internal spray hole 34, and the external spray hole 101. And under the pushing action of the pushing component, the hemostatic liquid medicine inside the cartridge 30 is squeezed out, that is, sprayed out from the external spray hole 101 to the bleeding position of the patient's digestive tract, achieving the hemostatic effect of inhibiting bleeding;

[0045] Through this device, in the case of lack of surgical conditions or emergencies, for patients with acute digestive tract bleeding, the patient can swallow the hemostatic capsule 1. When the hemostatic capsule 1 reaches the bleeding position in the patient's body, the drug release mechanism 3 releases the hemostatic liquid medicine to the bleeding position to quickly and temporarily inhibit digestive tract bleeding, creating time and conditions for the preparation of surgery.

[0046] Specifically, as Figures 3 - 4 shown, in order to enable the shutter 33 to move to the first position or the second position, in this embodiment, an electric push rod 35 with an arc-shaped structure is provided inside the drug release space 300. The piston rod of the electric push rod 35 is connected to one side of the shutter 33. Under the push of the electric push rod 35, the shutter 33 can move to the first position or the second position. It should be noted that: the outer wall of the shutter 33 fits with the inner wall of the hemostatic device 1, and there is a channel for the hemostatic liquid medicine to flow between the inner wall of the shutter 33 and the inner wall of the drug release space 300;

[0047] Specifically, in order to form a channel for the hemostatic liquid to flow between the inner wall of the baffle 33 and the inner wall of the drug release space 300, limiting blocks are provided at the four corner positions of the inner wall of the baffle 33. At the positions of the limiting blocks on the inner wall of the drug release space 300, limiting sliding grooves adapted to the limiting blocks are provided. The limiting blocks are slidably assembled in the limiting sliding grooves. When the baffle 33 moves, the limiting blocks slide in the limiting sliding grooves. This can not only ensure the stability of the movement of the baffle 33, but also, under the abutting action of the limiting blocks, form a channel for the hemostatic liquid to flow between the inner wall of the baffle 33 and the inner wall of the drug release space 300.

[0048] Specifically, as Figures 3 - 4 shown, in order to squeeze and push the hemostatic liquid in the cartridge 30 into the drug release space 300, so that the hemostatic liquid can have a certain kinetic energy when released, and ensure that the hemostatic liquid can fully contact the bleeding position, in this embodiment, the pushing assembly includes a medicine pressing plate 36 and a cylinder 31. Among them, the cylinder 31 is installed above the cartridge 30, the medicine pressing plate 36 is movably assembled inside the cartridge 30, and the piston rod of the cylinder 31 extends into the cartridge 30 and is connected to the medicine pressing plate 36. Therefore, when the cylinder 31 operates and pushes the medicine pressing plate 36 to move downward, the liquid medicine inside the cartridge 30 is squeezed and injected into the drug release space 300 through the drug release port 302, and then sprayed onto the digestive tract bleeding position of the patient with a certain kinetic energy to achieve the effect of inhibiting bleeding.

[0049] Specifically, as Figures 3 - 4 shown, in order to enable the hemostatic capsule 1 to release medicine to the corresponding positions at different angles in the digestive tract without rotation when releasing medicine, and avoid waste of the hemostatic liquid, in this embodiment, a plurality of partition ribs 301 are axially arranged in the drug release space 300. The drug release space 300 is divided into a plurality of independent regions by the plurality of partition ribs 301. At the bottom of each region, a drug release port 302 communicating with the inside of the cartridge 30 is correspondingly provided. An external spray hole 101 is provided on the hemostatic capsule 1 corresponding to each region, and an independent baffle 33 and an electric push rod 35 for controlling the movement of the baffle 33 are provided in each region. Based on this, when the hemostatic capsule 1 moves to the bleeding position, only the baffle 33 in the drug release space 300 corresponding to the angle of the bleeding position moves for precise drug release.

[0050] Specifically, as Figures 1 - 3 shown, in order to reduce the discomfort of the hemostatic device moving in the patient's digestive tract, in this embodiment, the hemostatic capsule 1 includes a housing 10, a transparent front cover 12 provided at the front end of the housing 10 and having a hemispherical structure, and a tail cover 11 detachably installed at the rear end of the housing 10 and having a hemispherical structure. Therefore, the discomfort of the hemostatic device moving in the patient's digestive tract can be reduced.

[0051] Specifically, as Figures 1 - 3As shown in the figure, in order to achieve illumination and image acquisition inside the patient's digestive tract, in this embodiment, a carrier plate 21 is provided inside the front end of the hemostatic capsule 1. A number of lamp beads 22 are distributed in a circular array along the edge of the carrier plate 21, and a camera 20 is installed in the middle of the carrier plate 21. The camera 20 can collect images of the inside of the patient's digestive tract through the transparent front cover 12, and then transmit them wirelessly to an external terminal. The doctor can view and understand the situation of the patient's digestive tract through the terminal. After reaching the bleeding position, the drug release mechanism 3 is remotely and wirelessly controlled to release the drug.

[0052] In addition, it should be noted that: in order to control the movement of the hemostatic capsule 1 in the patient's digestive tract, a magnet 102 is embedded in the wall of the hemostatic capsule 1. The control principle is as follows: First, an external device such as a magnetic field generator generates an adjustable magnetic field. The doctor can control the intensity and direction of the magnetic field to affect the movement trajectory of the capsule.

[0053] Specifically, when an external magnetic field acts on the magnet 102 on the hemostatic capsule 1, a magnetic force will be generated, causing the hemostatic capsule 1 to move in the digestive tract. By adjusting the direction and intensity of the magnetic field in real time, the forward and backward movement of the capsule can be precisely controlled.

[0054] Embodiment 2

[0055] As Figures 1 - 7 shown: This embodiment provides a technical solution: As Figure 3 、 Figures 5 - 7 shown, on the basis of Embodiment 1, in order to enhance the functionality of the hemostatic device so that it can extract samples of digestive tract lesions in special cases, in this embodiment, a sampling mechanism 4 is further provided inside the hemostatic capsule 1. Through the sampling mechanism 4, tissue samples can be extracted at the lesion location of the patient's digestive tract. The sampling mechanism 4 includes:

[0056] A tissue extraction window 100 opened on the hemostatic capsule 1;

[0057] A storage bin 40 provided inside the hemostatic capsule 1, and the storage bin 40 is located inside the tissue extraction window 100;

[0058] A cutter 44 provided inside the storage bin 40 for cutting and extracting tissues, and the cutter 44 is attached to the inner wall of the hemostatic capsule 1 at the tissue extraction window 100;

[0059] And a cutter control component, which is provided inside the hemostatic capsule 1 and is used to control the movement of the cutter 44 so that it can close the tissue extraction window 100 or cut and extract the tissue entering the tissue extraction window 100.

[0060] The process of extracting tissue samples from the lesion location in the patient's digestive tract is as follows: First, under normal conditions, the cutter 44 completely closes the tissue extraction window 100 under the action of the cutter control component. When the hemostatic capsule 1 moves to the lesion location and a sample from this location needs to be extracted, the cutter 44 moves under the action of the cutter control component to open the tissue extraction window 100. At this time, by controlling the movement of the hemostatic capsule 1, the tissue extraction window 100 is made to fit the lesion tissue, and a part of the lesion tissue will extend from the tissue extraction window 100 into the storage bin 40. Then, the cutter 44 is controlled by the cutter control component to move, cutting a part of the lesion tissue and leaving it in the storage bin 40, thus realizing the extraction of the digestive tract lesion tissue.

[0061] Specifically, as Figure 3 、 Figures 5 - 7 shown, in order to realize the control of the cutter 44, in this embodiment, the cutter control component includes:

[0062] A fixing piece 41, which is fixed to the outer wall of the storage bin 40;

[0063] A turntable 42, which is rotationally installed on the fixing piece 41 through a rotating shaft, and the axis of the turntable 42 coincides with the midline of the hemostatic capsule 1;

[0064] A motor 47, which is fixed to one side of the fixing piece 41, and the output shaft of the motor 47 is connected to the turntable 42;

[0065] A connecting rod 43, one end of which is fixed to the edge of the turntable 42 and the other end is connected to the middle part of the cutter 44. Based on this, when the motor 47 operates, it can drive the turntable 42 to rotate. Through the linkage of the connecting rod 43, the cutter 44 can be made to move along the inner wall of the hemostatic capsule 1, realizing the extraction of the digestive tract lesion tissue or the closing of the tissue extraction window 100.

[0066] Specifically, as Figure 3 、 Figures 5 - 7 shown, in order to enable the cutter 44 to move closely along the inner wall of the hemostatic capsule 1, in this embodiment, a front sleeve 45 and a rear sleeve 46 are respectively arranged on both sides of the inner wall of the hemostatic capsule 1 at the tissue extraction window 100. Among them, cavities 48 are arranged in both the front sleeve 45 and the rear sleeve 46. The cutter 44 is slidably assembled in the cavity 48 of the rear sleeve 46. The cutter 44 can move along the inner wall of the hemostatic capsule 1 under the control of the cutter control component, so that the front end of the cutter 44 is inserted into the cavity 48 in the front sleeve 45, realizing tissue cutting and extraction and the closing of the tissue extraction window 100. It should be noted that: a guide groove 49 for the movement of the connecting rod 43 is circumferentially opened on the inner side of the rear sleeve 46.

[0067] Specifically, as Figure 3 、 Figures 5 - 7As shown, in order to supply power to each electronic component inside the hemostatic capsule 1, in this embodiment, a power source 32 is provided inside the hemostatic capsule 1.

[0068] In the foregoing, the exemplary embodiments of the solutions proposed in the present disclosure have been described in detail with reference to the preferred embodiments.
