[0031] The present invention will be described in detail below with reference to the embodiments shown in the drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present invention.

[0032] Refer Figures 1 to 8 It should be noted that the Chinese terms "剖切" and "剖解" in the original text seem to be incorrect or non-standard technical terms. I have translated them as "sectional cutting" and "sectional dissection" respectively according to the context, but it is recommended to check the accuracy of these terms in the original technical content. Also, the tag Figures 1 to 8 remains unchanged as required.As shown, compared with the prior art, the visual ear-nose-throat hemostasis device of the present application is composed of a control body 1, a negative pressure hemostasis device 2 and an endoscope assembly 3, which can be inserted into the affected area to accurately check the bleeding point. The picture collected by the endoscope assembly 3 is displayed on the display device 4. By observing the image of the affected area magnified by tens of times displayed on the display device 4, the bleeding point can be accurately found. The field of view of the endoscope assembly 3 can be flexibly adjusted by inserting the catheter 12 and the endoscope assembly 3 into the affected area by holding the hand-held part 11, so that the bleeding point can be quickly and accurately found. Further, if there is a lot of blood in the affected area, it may interfere with the image collected by the endoscope assembly 3. The negative pressure hemostasis device 2 with the functions of negative pressure and electrocoagulation is used to suck the blood in the affected area into the collecting device 22, and clean water or other cleaning liquid is introduced into the annular flushing channel to flush the endoscope assembly 3, so that the blood remaining in the endoscope assembly 3 is flushed away, further ensuring the clarity of the picture collected by the endoscope assembly 3, further improving the efficiency of finding the bleeding point, and also being sucked into the collecting device 22 by the negative pressure hemostasis device 2. Finally, the electrocoagulation function of the negative pressure hemostasis device 2 is started to electrocoagulate the part where the bleeding point is found, and the whole hemostasis process is completed.

[0033] Referring to Figures 1 to 8 As shown, the visual ear-nose-throat hemostasis device (hereinafter referred to as a hemostasis device) of the present embodiment includes a control body 1, a negative pressure hemostasis device 2 and an endoscope assembly 3. The control body 1 includes a hand-held part 11 and a catheter 12. The negative pressure hemostasis device 2 is arranged through the catheter 12. The negative pressure hemostasis device 2 forms a negative pressure channel 21 along the axial direction. The hand-held part 11 is equipped with a collecting device 22 in communication with the negative pressure hemostasis device 2. The endoscope assembly 3 is arranged through the catheter 12 and parallel to the negative pressure hemostasis device 2. The endoscope assembly 3 is connected to a display device 4. The hand-held part 11 is held to make the catheter 12 drive the endoscope assembly 3 and the negative pressure hemostasis device 2 to extend into the affected area. The display device 4 displays the picture collected by the endoscope assembly 3. The catheter 12 forms an annular flushing channel 121 around the endoscope assembly 3. The catheter 12 has a liquid inlet 122 in communication with the annular flushing channel 121. The catheter 12 has a first channel 123 parallel to the negative pressure hemostasis device 2. The outer wall of the hand-held part 11 has a liquid supply pipe 1161 in communication with the first channel 123. The first channel 123 is detachably connected to a drug delivery pipe 1233. The drug delivery pipe 1233 is arranged to pass out from the end of the catheter 12 away from the hand-held part 11.

[0034] When the bleeding point in the ear, nose and throat is relatively hidden, and the conventional hemostasis method is difficult to apply, the visual ear, nose and throat hemostasis device in the embodiment is used for visual hemostasis, so as to quickly find the bleeding point and quickly stop bleeding. The hand-held part 11 is used to make the end of the catheter 12 extend into the ear / nose / pharynx / larynx cavity, and the endoscope assembly 3 can acquire the picture inside the cavity in real time and present it at the display device 4 in a multiple magnification state during the extension, so as to quickly and accurately acquire the image of the affected area and find the bleeding point. When the affected area has active bleeding and the amount of bleeding is large, a certain amount of blood may accumulate in the cavity, which may block the field of view of the endoscope assembly 3. The negative pressure channel 21 of the negative pressure hemostasis device 2 is used to suck out the blood in the cavity and collect it in the collecting device 22 connected with the negative pressure channel 21.

[0035] Further, part of the blood may still remain at the end face of the endoscope assembly 3, at which time the liquid inlet 122 formed in the catheter 12 is used to introduce cleaning liquid, and the cleaning liquid flows out of the catheter 12 through the annular flushing channel 121 arranged around the lens assembly 3 to clean the endoscope assembly 3, so as to further improve the clarity of the acquired picture of the affected area. The flushing liquid (such as pure water, physiological saline, etc.) flowing into the cavity is also introduced into the collecting device 22 by the negative pressure channel 21 of the negative pressure hemostasis device 3. It should be noted that the liquid inlet 122 in the embodiment is a pipe body formed at the top end of the catheter 12 and arranged at a certain inclination, which can be extended by a needle tube or other connecting device. The cleaning liquid is pushed into the annular flushing channel 121 by manually pushing the medicine or an electric pump. The cleaned endoscope assembly 3 acquires the image of the affected area without blood contamination, and the coagulation function of the negative pressure hemostasis device 2 is started to contact the bleeding point and quickly stop bleeding. It should be noted that when the affected area has diffuse bleeding and it is difficult to stop bleeding, the drug (such as adrenaline or other drugs) is injected into the affected area through the administration tube 1233 in the embodiment for auxiliary treatment, so as to effectively and tightly stop bleeding at the bleeding point.

[0036] Referring to FIG. 1, the specific embodiments will be described in detail. Figures 1 to 8 Figure 8 ​As shown, the catheter 12 comprises a first connecting section 124 and a second connecting section 125, one end of the first connecting section 124 is fixed to the handheld part 11, the other end of the first connecting section 124 extends away from the handheld part 11; one end of the second connecting section 125 is detachably connected with the first connecting section 124, the endoscope assembly 3, the negative pressure hemostasis device 2 and the administration tube 1233 are led out from the other end of the second connecting section 125 away from the first connecting section 124; the first channel 123 formed in the first connecting section 124 is tapered at the end abutting with the second connecting section 125 to form a tapered connecting tube 1231, the administration tube 1233 is sleeved on the tapered connecting tube 1231, the abutting end of the second connecting section 125 with the first connecting section 124 forms an inner tapered surface 1232 adapted to the tapered connecting tube 1231, the inner tapered surface 1232 and the tapered connecting tube 1231 abut the inner and outer sides of the administration tube 1233. The handheld part 11 is formed with a containing cavity 112, the side of the handheld part 11 is formed with a mounting seat 115, the administration device 116 is detachably connected at the mounting seat 115, the administration cavity 1162 communicating with the liquid feeding tube 1161 and the first channel 123 is formed in the containing cavity 112, the administration device 116 injects medicine into the first channel 123 and the administration tube 1233 through the liquid feeding tube 1161 and the administration cavity 1162.

[0037] It should be noted that the administration tube 1233 is a disposable medical device that extends into the patient's body, so it needs to be replaced after each use. In this embodiment, the catheter 12 is designed to be composed of a first connecting section 124 of the main body and a second connecting section 125 that is detachably connected to the first connecting section 124, so as to achieve the purpose of easily replacing the administration tube 1233. Further, in this embodiment, the optical lens 31 of the endoscope assembly 3 is fixed to the end face where the first connecting section 124 and the second connecting section 125 are connected, and the second connecting section 125 and the first connecting section 124 are connected to each other by an elastic buckle. When the administration tube 1233 needs to be removed, the second connecting section 125 is slightly forced to be removed from the end of the first connecting section 124, the administration tube 1233 that is sleeved on the tapered connecting tube 1231 is removed, and then the entire hemostatic device can be sterilized according to the actual situation. After sterilization, a new administration tube 1233 is sleeved on the outer wall of the tapered connecting tube 1231, which can provide stable support force to the administration tube 1233 to support the inner wall of the administration tube 1233, so that the medicine can flow, and then the second connecting section 125 is connected to the end face of the first connecting section 124, which has an inner tapered surface 1232 abutting against the outer wall of the administration tube 1233, maintaining the stability of the assembled administration tube 1233 without removing the second connecting section 125, to avoid the administration tube 1233 from falling off. Through the above design of the structure of the first connecting section 124 and the second connecting section 125, the administration tube 1233 can be easily replaced, and the medicine can flow smoothly and without leakage into the administration tube 1233 after flowing through the first channel 123, which is beneficial to the medicine flowing into the affected area for hemostasis.

[0038] Further, in this embodiment, a mounting seat 115 is formed on the side wall of the hand-held portion 11, which is a ring-shaped member with a certain elasticity and a notch in the middle, as shown in Figure 1 The liquid supply tube 1161 is formed in an inclined attitude on the side wall of the hand-held portion 11 and communicates with the administration channel 1162 formed in the hand-held portion 11, and the administration device 116 can be inserted into the liquid supply tube 1161 through a needle tube (not shown) or other connecting tube member arranged in the same inclined direction as the liquid supply tube 1161 to provide medicine to the administration channel 1162 and the first channel 123. Further, in order to provide stability for the medicine, the administration device 116 can be provided with an electric pump (not shown) to achieve the purpose of uniform flow rate of the medicine.

[0039] Referring to Figure 7As shown, the top surface of the hand-held part 11 is provided with a control panel 111 which is arranged in an inclined manner away from the catheter 12. A circuit board 113 is arranged in the accommodating cavity 112 of the hand-held part 11 in parallel to the control panel 111. The circuit board 113 is connected to the endoscope assembly 3, the negative pressure hemostasis device 2 and the display device 4 through connecting lines (not labeled) respectively. The negative pressure hemostasis device 2 is selected as a hollow metal pipe. The control panel 111 is provided with a control button 1111 which is connected to the circuit board 113. The control button 1111 is used to control the on-off and power of the electrocoagulation function of the negative pressure hemostasis device 2. The side of the hand-held part 11 away from the catheter 12 is provided with a mounting groove 114 in which the collecting device 22 is detachably connected. The collecting device 22 is provided with a connecting port 221 which extends into the accommodating cavity 112 and is in communication with the negative pressure hemostasis device 2. The collecting device 22 is provided with a negative pressure button 222. One end of the negative pressure hemostasis device 2 located in the accommodating cavity 112 is inserted into the connecting port 221 of the collecting device 22.

[0040] It should be noted that one control button 1111 can be arranged at the control panel 111 to control the on-off and power of the electrocoagulation function of the negative pressure hemostasis device 2 simultaneously. For example, the on-off of the electrocoagulation function of the negative pressure hemostasis device 2 is controlled by pressing the control button 1111, and the power is controlled by rotating the control button 1111. Or, the on-off and power of the electrocoagulation function of the negative pressure hemostasis device 2 are controlled by the number of times of pressing the control button 1111. The specific implementation is not described herein. Or, as shown in the state, Figure 2 two control buttons 1111 are arranged at the control panel 111 to control the on-off and power of the electrocoagulation function of the negative pressure hemostasis device 2 respectively. In this embodiment, the control panel 111 is arranged in an inclined manner at the tail end of the hand-held part 11. In the holding state, the operator can operate the control button 1111 on the control panel 111 in a relatively convenient manner. Further, an indicator light or the like can be arranged at the control panel 111 to further improve the convenience of the operator in controlling the negative pressure hemostasis device 2. In addition, the circuit board 113 is arranged in the accommodating cavity 112 in parallel to the control panel 111. The circuit board 113 has the basic function of being electrically connected to each component, and can occupy less space in the accommodating cavity 112 so that the mounting groove 114 for arranging the collecting device 22 is formed at the hand-held part 11.

[0041] In this embodiment, the collecting device 22 is entirely made of soft plastic material, and the negative pressure button 222 of the collecting device 22 can be set as a button (not shown) forming a number of lip-shaped folding parts. By pressing the negative pressure button 222, the pressure inside the collecting device 22 is changed, so as to achieve the purpose of sucking bloodstains into the collecting device 22 through the negative pressure channel 21 of the negative pressure hemostasis device 2. It should be noted that in this embodiment, the collecting device 22 is formed into a structure with a relatively gentle upper part and a curved lower part, and the connection port 221 of the collecting device 22 is integrally formed at a position near its upper part. After the collecting device 22 is inserted into the installation groove 114, the connection port 221 is docked with the negative pressure hemostasis device 2. After the blood enters the collecting device 22, it flows under the action of gravity to the curved position below it. When the blood in the collecting device 22 is collected to a certain amount and taken out from the installation groove 114, a certain height difference is maintained between the internal liquid level and the connection port 221 to prevent the internal blood from leaking. Further, a friction increasing member such as a rubber ring (not shown) can be provided at the position where the connection port 221 passes through the installation groove 114 to improve the installation stability of the collecting device 22.

[0042] As shown Figures 2 to 7 in the figure, the endoscope assembly 3 includes an optical lens 31, an optical fiber 32 and an imaging device 33. The imaging device 33 is assembled in the accommodation cavity 112 and connected to the circuit board 113. The optical fiber 32 is disposed in the catheter 12 and one end is docked with the imaging device 33, and the other end is docked with the optical lens 31. The length of the negative pressure hemostasis device 2 extending from the second connection section 125 is greater than the length of the optical lens 31 of the endoscope assembly 3 extending from the second connection section 125. A tapered guiding surface (not marked) is formed between the outer edge of the second connection section 125 and its end surface away from the first connection section 124. In this embodiment, the display device 4 is set as a display screen 41a installed on the top of the handheld part 11 through a connecting pipe fitting 42a. A relief opening 117 is formed at the bottom end of the handheld part 11, and an electrical connection port 118 is assembled at the relief opening 117. The electrical connection port 118 is connected to the circuit board 113.

[0043] It should be noted that, since the negative pressure hemostatic device 2 has a high temperature when the electrocoagulation function is turned on and contacts the bleeding point, the length of the second connecting section 125 of the negative pressure hemostatic device 2 is extended to avoid damage to the optical lens 31 caused by the high temperature during the hemostasis process of the negative pressure hemostatic device 2. Further, as known from the foregoing, in the present embodiment, the optical lens 31 is fixed to the end face of the first connecting section 124 so that the first connecting section 124 and the second connecting section 125 are in mutual abutment, the guide surface formed on the second connecting section 125 can further reduce the diameter of the end portion of the second connecting section 125 and reduce the sharp portion of the second connecting section 125 so as to extend into the catheter 12 to drive the optical lens 31 and the negative pressure hemostatic device 2 to extend into the cavity. Further, the arrangement of the optical fiber 32, the annular flushing channel 121, the first channel 123, and the negative pressure hemostatic device 2 in the first connecting section 124 is as shown in Figure 4 The arrangement method organically combines the visualization function of the endoscope assembly 3, the flushing function of the endoscope assembly 3, the blood removal and hemostasis functions of the negative pressure hemostatic device 2, and the function of the first channel 123 of the annular flushing channel 121 to inject medicine into the affected area through the drug delivery tube 1233, and finally forms a mutual abutment of each component in the hand-held portion 11, thereby forming an ear-nose-throat hemostatic device with perfect functions, which is suitable for most bleeding symptoms in the ear-nose-throat department. Further, in the present embodiment, the display screen 41a is assembled on the top of the hand-held portion 11, which further improves the compactness and convenience of the overall structure of the hemostatic device, and is suitable for places without large medical equipment. It should be noted that, in the present embodiment, the connecting tube 42a can be a serpentine tube or any other tubular member that is easy to bend and adjust the angle. When hemostasis is needed, an external power supply is connected through the electrical connection port 118, and the affected area is directly observed at the display screen 41a to find the bleeding point.

[0044] Referring to Figure 9 Fig. 6, another embodiment of the visual ear-nose-throat hemostatic device disclosed in the present application is shown, which is different from the foregoing embodiments in that: in the present embodiment, the display device 4 includes a support 42b and a display screen 42a assembled on the top of the support 42b, and the bottom end of the hand-held portion 11 is provided with a clearance 117, and the electrical connection port 118 is assembled at the clearance 117, the electrical connection port 118 is connected to the circuit board 113, and the electrical connection port 118 is connected to the display screen 42a through the connecting line 43.

[0045] Different from the foregoing embodiments, the display device 4 composed of the support 42b and the display screen 42a in the present embodiment has a larger volume, the display screen 42a has a relatively larger display area, and the display device 4 can present the images of the affected part acquired by the endoscope assembly 3 at a larger magnification, and is suitable for a diagnosis and treatment site with a larger space. Further, in the present embodiment, the support 42b is selected to be a foldable tripod, the display screen 42a is assembled at the top end of the support 42b in a threaded connection or any other detachable manner, and the display screen 42a is detached from the top end of the support 42b and the support 42b is folded to be stored, respectively, so as to have the advantages of larger image magnification and convenient storage and movement. In use, the display screen 42a and the electrical connection port 118 are connected through the connecting line 43, so as to achieve the purpose of supplying power to the endoscope assembly 3 and the negative pressure hemostasis device 2, and transmit the image signal to the display screen 42a through the connecting line 43.
