DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

The medical hemostasis device 100 according to the embodiment of the present application is described in detail below with reference to the accompanying drawings 1 to 4 of the specification.

As shown in FIG. 1 and FIG. 2 , a medical hemostasis device 100 is used in a medical environment where the medical hemostasis device 100 is inserted into the body of a patient through a natural orifice of the patient or a duct formed by trauma to treat a wound in the patient's body. For example, the patient is injured and has internal bleeding problems, or it can be used in a battlefield environment where a part of the body of the injured person is ruptured, causing bleeding points, and timely hemostasis is required.

Therefore, the medical hemostasis device 100 of the embodiment of the utility model can increase the pipe diameter of the operation channel 302 to deliver more therapeutic substances in a short time and achieve a better hemostasis effect.

A medical hemostasis device 100 according to an embodiment of the utility model includes a main body 10 and a mechanical arm assembly 30. The main body 10 can be electrically connected to an external power source. The main body 10 is the main control device of the medical hemostasis device 100, and can be controlled by a medical staff as a user. The main body 10 controls the overall movement of the medical device, such as controlling the mechanical arm 301 to control the movement direction of the operating channel 302, so that the bleeding point of the injured person can be found more accurately.

The robot arm assembly 30 includes a robot arm 301 and an operating channel 302, and one end of the operating channel 302 is connected to the main body 10. The movement of the operating channel 302 can be operated by the main body 10, and the medicine can be delivered through the operating channel 302. Since the robot arm 301 has more rotation angles, the robot arm 301 can control the operating channel 302 to rotate in more directions. It is convenient to control the movement of the operating channel 302. And because there are multiple organs in the human body, the wounds of some patients are in a more complex position in the patient's body due to the obstruction of the organs. Therefore, the robot arm 301 can effectively control the operating channel 302 to avoid other organs in the patient's body, and accurately deliver the hemostatic drug to the patient's wound.

Furthermore, the diameter of the operation channel 302 is between 0.5 mm and 1 cm. Therefore, compared with the operation channel of a general medical hemostasis device, the diameter of the operation channel 302 is increased, and more drugs can be delivered in a short time when the patient's wound is bleeding heavily, thereby improving the hemostasis effect. And larger drug particles can also be delivered. The operation channel 302 uses a hose, which can be easy to operate. And the mechanical arm 301 can be electrically connected to the main body 10. When the operation channel 302 is extended into the patient's body to stop bleeding from the patient's internal wound, the mechanical arm 301 controls the movement of the operation channel 302.

In addition, due to the increase in the diameter of the operation channel 302, it is also possible to conveniently deliver therapeutic substances to the patient's internal wound, and the therapeutic substances can be used as a hemostatic tool. Therefore, there is a more appropriate option for the patient's wound to quickly stop bleeding, which is beneficial to improving the treatment of the patient.

In some embodiments of the present invention, the treatment includes a hemostatic clip, which can be inserted into the patient's body through the operation channel 302 to stop bleeding of the wound in the body. The clamping action of the hemostatic clip can effectively clamp the patient's wound, and because the diameter of the operation channel 302 is increased, it is convenient for the hemostatic clip to enter the patient's body through the operation channel 302 to perform a hemostatic operation.

In some embodiments of the present invention, the treatment includes an electrocoagulation device, which can be inserted into the patient's body through the operation channel 302 to seal the patient's internal wound. The electrocoagulation function of the electrocoagulation device can effectively seal the patient's wound through electrocoagulation, and because the diameter of the operation channel 302 is increased, it is convenient for the electrocoagulation device to enter the patient's body through the operation channel 302 to perform a hemostasis operation.

In some embodiments of the present invention, the therapeutic substance includes a hemostatic agent, and the hemostatic agent includes at least one of a powdered agent, a liquid agent, or a solid agent, so as to facilitate the use of a combination of multiple agents to quickly treat the patient.

According to a medical hemostasis device 100 of an embodiment of the utility model, it can be extended into the patient's body to deliver hemostatic drugs to the wound in the patient's body for hemostasis. By increasing the diameter of the operating channel 302, the short-term hemostatic drug delivery amount can be increased, and the hemostatic effect can be effectively improved. In addition, therapeutic substances can be delivered, and there are more options for rapid hemostasis of the patient's wound. It is beneficial to improve the treatment of patients. The mechanical arm 301 can drive the movement of the operating channel 302. Compared with the existing medical hemostasis device 100, the operating channel 302 can be driven by the mechanical arm 301 to rotate in more directions, which is more flexible to use and convenient for accurately delivering hemostatic drugs to the patient's wound. In addition, the operating channel 302 uses a hose to improve the flexibility of movement.

In some embodiments of the present invention, as shown in FIG. 3 , the robot arm 301 may adopt a snake-bone structure of the robot arm 301 , so that it may have more rotation angles, thereby facilitating the control of the rotation direction of the infusion tube 302 .

In some embodiments of the present invention, as shown in FIG. 1 , the medical hemostasis device 100 further includes a flow limiting valve 50 , which is disposed between the robotic arm assembly 30 and the main body 10 to control the amount of medicine delivered by the medical hemostasis device 100 to the patient's wound.

Specifically, a flow limiting valve 50 is provided between the main body 10 and the mechanical arm assembly 30, which can effectively control the amount of medicine delivered through the operating channel 302, such as liquid medicine. Through the control of the flow limiting valve 50, different amounts of medicine can be delivered for different wound sizes of different patients. For example, the wound of patient A is relatively large, so a large amount of hemostatic medicine needs to be delivered in a short time. Therefore, by adjusting the flow limiting valve 50 to the maximum opening, a large amount of hemostatic medicine can be delivered in a short time to stop bleeding of the wound of patient A. The wound of patient B is relatively small, so the opening of the flow limiting valve 50 can be reduced to reduce the delivery amount of hemostatic medicine. Through the setting of the flow limiting valve 50, hemostatic medicine can be delivered to the patient's wound more accurately. To prevent drug waste.

Furthermore, since some drugs have a certain single-use limit, the flow limiting valve 50 can better control the drug delivery amount to prevent excessive drug use.

In some embodiments of the present invention, the operation channel 302 includes at least two operation channels 302. The at least two can be at least two, or three, four, or more. Therefore, by increasing the operation channels 302, the diversity of drugs used can be increased, and multiple different drugs can be delivered at the same time, which is convenient for comprehensive treatment.

The following description will be made by taking the operation channel 302 having two operation channels 302 as an example.

Specifically, since the operation channel 302 has two operation channels 302, different drugs can be respectively delivered in the two operation channels 302. Two different drugs can be delivered to the wound of the patient at the same time for treatment.

For example, drug C can be delivered in one of the operation channels 302, and drug D can be delivered in another operation channel 302. Therefore, different medication treatment methods are used for different wounds of patients. For example, the wounds of some patients may have a better effect when drug C is used, so drug C can be used for the wounds of the patients. The wounds of some patients may have a better effect when drug D is used, so drug D can be used for the wounds of the patients. The wounds of some patients may need to use drugs C and D together for a better effect, so drugs C and D can be used simultaneously for the wounds of the patients.

In some embodiments of the present invention, the medical hemostasis device 100 may further include a negative pressure suction part, which is arranged at one end of the operation channel 302 extending into the patient's body to absorb foreign matter from the patient's wound.

Specifically, a negative pressure suction part is provided at one end of the operating channel 302 of the medical hemostasis device 100 that extends into the patient's body. The wounds of some patients are caused by foreign bodies penetrating through them, and some soft tissues may be sunken at the wound, which will sink into the wound and block the bleeding point of the wound, hindering the doctor from delivering hemostatic drugs to the wound and hindering the healing of the wound. When treating such wounds, it is necessary to suck the soft tissue trapped inside the wound back to its normal position, so the negative pressure suction part can suck out the soft tissue there and expose the bleeding point at the wound, making it easier to deliver the hemostatic drug to the bleeding location accurately. This improves the hemostatic effect.

For some patients whose internal wounds are penetrated by foreign objects, although the foreign objects are removed, there may be foreign body fragments in the wound that are temporarily difficult to remove. Therefore, the negative pressure suction part can be extended into the patient's body to suck out the smaller foreign body fragments, which is convenient for subsequent treatment.

In some embodiments of the present invention, the medical hemostasis device 100 further includes a gel spraying portion, which is disposed at one end of the operation channel 302 extending into the patient's body.

Specifically, after applying hemostatic drugs to the wounds of some patients, due to the large wounds, in order to facilitate wound healing and subsequent recovery of the wounds, medical gel can be applied to the soft tissue at the wound through the gel spraying part, so as to adhere the wound and further improve the hemostatic effect. This can be beneficial for short-term hemostasis of patients with large wounds, and facilitate the subsequent treatment of patients.

In some embodiments of the present invention, as shown in FIG2 , the mechanical arm assembly 30 further includes a terminal portion 303. The terminal portion 303 is arranged at the end of the operation channel 302 extending into the patient's body. In other words, the terminal portion 303 is the end extending into the patient's body, and the outer diameter of the terminal portion 303 is about 15 mm. This facilitates the terminal portion 303 to extend into the patient's body to treat the patient's wound.

In some embodiments of the present invention, as shown in FIG2 , the robot arm assembly 30 further includes a nozzle 304. The nozzle 304 is provided to the end portion 303 to supply air or water toward the patient's internal wound. Specifically, the nozzle 304 is provided to the end portion 303 to spray water and supply air toward the camera 306, and the air supply volume is at least 800 ml (milliliter) / min (minute). The camera 306 can be cleaned and blown dry.

In some embodiments of the present invention, as shown in Fig. 2, the mechanical arm assembly 30 further includes an illumination member 305. The illumination member 305 is provided to the end portion 303, and the illumination member 305 can be used as an illumination device to facilitate detection of the patient's injury and hemostasis operation in the patient's body.

In some embodiments of the present invention, as shown in FIG2 , the mechanical arm assembly 30 further includes a camera 306. The camera 306 is provided to the end portion 303. The camera 306 can be used to transmit images of the wound position in the patient's body, so that medical staff can observe the patient's wound.

In some embodiments of the present invention, as shown in FIG. 2 , the robot arm assembly 30 further includes an auxiliary water supply pipe 307 , through which water can be supplemented.

In some embodiments of the present invention, the outside of the mechanical arm assembly 30 may be covered with a protective cover, which may be made of medical rubber material, and the operation channel 302 is a hose embedded in the protective cover, so that the mechanical arm 301 and the operation channel 302 inside are protected by the protective cover, so that the mechanical arm assembly 300 is more hygienic.

For the robot arm assembly 30, the overall outer diameter can be about 15 mm (millimeter), and the overall length of the entire robot arm assembly 30 can be about 1350 mm. The length of the robot arm assembly 30 extending into the patient's body can be about 1030 mm. Among them, the minimum visual distance of the camera 306 can be 3 mm, the field of view angle it has is about 140°, and the direct field of view direction has a certain depth of field between 3-100 mm. And the end head 303 can be controlled by the robot arm 301 to rotate in multiple directions, for example, six-axis rotation can be achieved, thereby improving the overall control freedom and flexibility of the robot arm assembly 30.

In some embodiments of the present invention, as shown in FIG4 , the medical hemostasis device 100 further includes a control system 20 and an endoscope 70. The control system 20 is electrically connected to the main body 10 so that the main body 10 can operate the mechanical arm 301. Specifically, the main body 10 can be set on the control system 20, so that the main body 10 can be used as a joystick to operate the mechanical arm 301 to perform hemostasis. The endoscope 70 is set to the control system 20, and the endoscope 70 is electrically connected to the camera 306 so that the endoscope 70 is connected to the camera 305 to view the position of the end portion 303 in the patient's body. That is, the endoscope 70 can be used as an image display device to display the image of the patient's wound observed by the camera 306.

In some embodiments of the present invention, the main body 10 and the control system 20 are detachably connected.

It is understandable that in a medical environment, especially in a battlefield medical environment, due to the limitation of conditions, it is impossible to use a medical device on a patient and then disinfect it for another patient. Therefore, it is necessary to improve the safety and hygiene of medical equipment. Therefore, by adopting a detachable connection between the main body 10 and the control system 20, that is, after delivering hemostatic drugs to a patient's wound through a mechanical arm assembly 30, the used mechanical arm assembly 30 and the main body 10 can be disassembled and discarded. When the next patient is given hemostatic treatment, a new mechanical arm assembly 30 is used.

Therefore, the use hygiene of the medical hemostasis device 100 is improved, ensuring high safety for each patient and preventing bacterial infection among multiple patients.

In some embodiments of the present invention, the medical hemostasis device 100 further includes a driving system and a sensing system, and the driving system and the sensing system can better cooperate with the mechanical arm assembly 30 to treat the patient.

According to a medical hemostasis device 100 of an embodiment of the utility model, it can be inserted into the patient's body to deliver hemostatic drugs to the wound in the patient's body to stop bleeding. By increasing the diameter of the operating channel 302, the short-term hemostatic drug delivery amount can be increased, effectively improving the hemostatic effect. The provided mechanical arm 301 can drive the movement of the operating channel 302. Compared with the existing medical hemostasis device 100, the operating channel 302 can be driven by the mechanical arm 301 to rotate in more directions, which is more flexible to use and convenient for accurately delivering hemostatic drugs to the patient's wound. In addition, the operating channel 302 uses a hose to improve the flexibility of movement.

The above implementation methods are only used to illustrate the embodiments of the present application, and are not limitations on the embodiments of the present application.
