[0031] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0032] Ginseng Figures 1 to 8As shown, an embodiment of a visualized otolaryngology hemostasis device disclosed by the present invention is provided. Compared with the prior art, the visualized otolaryngology hemostasis device composed of a control body 1, a negative pressure hemostasis device 2 and an endoscope assembly 3 can be extended into the affected part to accurately check the bleeding point. The endoscope assembly 3 collects the image of the affected part and presents it on the display device 4. The image of the affected part magnified dozens of times by the display device 4 can achieve the purpose of accurately finding the bleeding point. By holding the handheld part 11 to allow the catheter 12 and the endoscope assembly 3 to be extended into the affected part, the field of view of the endoscope assembly 3 can be flexibly adjusted to achieve the purpose of quickly and accurately finding the bleeding point. Furthermore, if there are a lot of bloodstains on the affected part, which may interfere with the image collected by the endoscope assembly 3, the present invention uses a negative pressure hemostasis device 2 that combines negative pressure and electrocoagulation functions to attract the bloodstains on the affected part into the collection device 22, and introduces clean water or other cleaning fluids through the annular flushing channel to flush the endoscope assembly 3, flushing away the blood remaining in the endoscope assembly 3, further ensuring the clarity of the image collected by the endoscope assembly 3, further improving the efficiency of finding the bleeding point, and also attracting the bloodstains to the collection device 22 by the negative pressure hemostasis device 2. Finally, the electrocoagulation function of the negative pressure hemostasis device 2 is activated to electrocoagulate the bleeding point at the site where the bleeding point is found, completing the entire hemostasis process.

[0033] Ginseng Figures 1 to 8 As shown, the visualized otolaryngology hemostasis device (hereinafter referred to as the hemostasis device) in this 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, and the hand-held part 11 is equipped with a collecting device 22 connected to the negative pressure hemostasis device 2; the endoscope assembly 3 passes through the catheter 12 and is arranged parallel to the negative pressure hemostasis device 2, the endoscope assembly 3 is connected to the display device 4, the hand-held part 11 is held so that the catheter 12 drives the endoscope assembly 3 and the negative pressure hemostasis device 2 to extend into the affected area, and the display device 4 presents the picture collected by the endoscope assembly 3; the catheter 12 forms an annular flushing channel 121 around the endoscope assembly 3, and the catheter 12 has a liquid inlet 122 connected to the annular flushing channel 121. The catheter 12 opens a first channel 123 parallel to the negative pressure hemostasis device 2. The outer wall of the hand-held part 11 has a liquid feeding tube 1161 connected to the first channel 123. The first channel 123 is detachably connected to a drug delivery tube 1233, and the drug delivery tube 1233 passes through the end of the catheter 12 away from the hand-held part 11.

[0034] When the bleeding points in the otolaryngology are relatively hidden and conventional hemostasis methods are difficult to apply, the visualized otolaryngology hemostasis device in this embodiment is used for visualized hemostasis, so as to achieve the effect of quickly finding the hemostasis point and quickly stopping the bleeding point. The hand-held portion 11 is held to extend the end of the catheter 12 into the ear / nose / pharynx / throat cavity. During the insertion of the catheter 12, the endoscope assembly 3 can obtain the image inside the cavity in real time and present it on the display device 4 in a multi-fold magnified state, so as to quickly and accurately obtain the image of the affected part and find the bleeding point. When the affected part has active bleeding and the amount of bleeding is large, there may be a certain amount of blood stagnation in the cavity, which causes the field of view of the endoscope assembly 3 to be blocked. The blood in the cavity is sucked out through the negative pressure channel 21 of the negative pressure hemostasis device 2 and collected in the collection device 22 connected to the negative pressure channel 21.

[0035] Further, some blood may still remain on the end surface of the endoscope assembly 3. At this time, a cleaning liquid is introduced into the liquid inlet 122 formed in the catheter 12, and the cleaning liquid flows out of the catheter 12 through the annular flushing channel 121 set around the lens assembly 3 to clean the endoscope assembly 3, so as to further improve the clarity of the acquired image of the affected part. 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 in this embodiment, the liquid inlet 122 is set as a tube body formed at the top of the catheter 12 and set at a certain inclination, which can be extended through a connecting device such as a needle tube, and the cleaning liquid is pushed into the annular flushing channel 121 by manually pushing medicine or an electric pump body. The cleaned endoscope assembly 3 obtains an image of the affected part that is not contaminated by blood stains, and the electrocoagulation function of the negative pressure hemostasis device 2 is activated. The purpose of quickly stopping bleeding at the bleeding point is achieved by the contact between the negative pressure hemostasis device 2 and the bleeding point. It should be noted that when diffuse hemostasis occurs in the affected area and hemostasis is difficult, in this embodiment, drugs (such as adrenaline or other drugs) are injected into the affected area through the drug delivery tube 1233 for auxiliary treatment to effectively and strictly stop the bleeding point.

[0036] Ginseng Figures 1 to 8 As shown, the specific Figure 8As shown, the catheter 12 includes a first connecting section 124 and a second connecting section 125, one end of the first connecting section 124 is fixed to the hand-held portion 11, and the other end of the first connecting section 124 extends in a direction away from the hand-held portion 11; one end of the second connecting section 125 is detachably connected to the first connecting section 124, and the endoscope assembly 3, the negative pressure hemostasis device 2 and the drug delivery tube 1233 pass through the end of the second connecting section 125 away from the first connecting section 124; the first channel 123 opened by the first connecting section 124 is located at the end connected to the second connecting section 125 to form a conical connecting tube 1231, and the drug delivery tube 1233 is sleeved on the conical connecting tube 1231, and the inner conical surface 1232 adapted to the conical connecting tube 1231 is formed at the connection between the second connecting section 125 and the first connecting section 124, and the inner conical surface 1232 and the conical connecting tube 1231 abut against the inner and outer sides of the drug delivery tube 1233. A accommodating cavity 112 is formed in the hand-held portion 11, and a mounting seat 115 is formed on the side of the hand-held portion 11. A drug delivery device 116 is detachably connected to the mounting seat 115. A drug delivery channel 1162 connecting a liquid feeding tube 1161 and the first channel 123 is formed in the accommodating cavity 112. The drug delivery device 116 injects drugs into the first channel 123 and the drug delivery tube 1233 through the liquid feeding tube 1161 and the drug delivery channel 1162.

[0037] It should be noted that the drug delivery tube 1233 is a disposable medical device inserted 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 detachably connected to the first connecting section 124 to achieve the purpose of easily replacing the drug delivery tube 1233. Further, in this embodiment, the optical lens 31 of the endoscope assembly 3 is fixedly connected to the end surface 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 in an elastic buckle manner. When it is necessary to disassemble the drug delivery tube 1233, the second connecting section 125 is removed from the end of the first connecting section 124 with a little force, and the drug delivery tube 1233 sleeved on the tapered connecting tube 1231 is removed, and then the hemostatic device can be disinfected as a whole according to actual conditions. After disinfection, the new dosing tube 1233 is sleeved on the outer wall of the tapered connecting tube 1231, and the outer wall can provide a stable support force for the dosing tube 1233 to open the inner wall of the dosing tube 1233 so that the medicine can flow. Then the second connecting section 125 is connected to the end face of the first connecting section 124, and the inner conical surface 1232 thereof abuts against the outer wall of the dosing tube 1233, and the stability of the assembly of the dosing tube 1233 is maintained when the second connecting section 125 is not removed, so as to prevent the dosing tube 1233 from falling off. The above-mentioned design of the structure of the first connecting section 124 and the second connecting section 125 can achieve the effect of easy replacement of the dosing tube 1233, and when the medicine flows through the first channel 123, it can flow smoothly and without leakage into the dosing tube 1233, which is conducive to the flow of the medicine into the affected area for hemostasis.

[0038] Furthermore, in this embodiment, a mounting seat 115 is formed on the side wall of the handheld portion 11. The mounting seat 115 is as follows: Figure 1 The annular member with a certain elasticity and a notch in the middle is shown, and the drug delivery device 116 is embedded in the mounting seat 115 and docked with the liquid delivery tube 1161. Specifically, the liquid delivery tube 1161 is formed on the side wall of the handheld portion 11 in an inclined posture and communicates with the drug delivery channel 1162 formed in the handheld portion 11. The drug delivery device 116 can be inserted into the liquid delivery tube 1161 through a needle tube (not shown) or other connecting pipes arranged in the same inclined direction as the liquid delivery tube 1161 to provide drugs to the drug delivery channel 1162 and the first channel 123. Further, in order to provide stability in drug delivery, the drug delivery device 116 can be provided with an electric pump (not shown) to achieve the purpose of uniform drug flow rate.

[0039] 2 to Figure 7As shown, the top surface of the handheld part 11 and the side of the handheld part 11 away from the catheter 12 form an inclined control panel 111, and a circuit board 113 is installed in the accommodating cavity 112 of the handheld part 11 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 wires (not marked), and the negative pressure hemostasis device 2 is selected as a hollow metal tubular member. The control panel 111 has a control button 1111 connected to the circuit board 113, and the control button 1111 is used to control the opening and closing of the electrocoagulation function and the power level of the negative pressure hemostasis device 2. A mounting groove 114 is formed on the side of the hand-held portion 11 away from the catheter 12, and a collecting device 22 is detachably connected to the mounting groove 114. The collecting device 22 has a connecting port 221, which extends into the accommodating chamber 112 and is connected to the negative pressure hemostasis device 2. The collecting device 22 has a negative pressure button 222, and one end of the negative pressure hemostasis device 2 located in the accommodating chamber 112 is inserted into the connecting port 221 of the collecting device 22.

[0040] It should be noted that the control panel 111 can be equipped with a control button 1111 to simultaneously control the on / off and power level of the electrocoagulation function of the negative pressure hemostasis device 2. For example, the on / off of the electrocoagulation function of the negative pressure hemostasis device 2 can be controlled by pressing the control button 1111, and its power level can be controlled by rotating it, or the on / off and power level of the electrocoagulation function of the negative pressure hemostasis device 2 can be controlled by pressing the control button 1111. The details will not be described in detail. Figure 2 In the state shown, two control buttons 1111 are formed at the control panel 111 to respectively adjust the opening and closing of the electrocoagulation function and the power strength of the negative pressure hemostasis device 2. In this embodiment, by tilting the control panel 111 formed at the rear end of the handheld portion 11, the operator can operate the control buttons 1111 on the control panel 111 in a relatively convenient posture when holding it. Furthermore, components such as indicator lights can be formed at the control panel 111 to further improve the convenience of the operator's control of the negative pressure hemostasis device 2. In addition, the circuit board 113 is arranged in the accommodating cavity 112 in an inclined posture parallel to the control panel 111. While having the basic function of being electrically connected to each component, it can occupy less space in the accommodating cavity 112, so that the handheld portion 11 forms a mounting groove 114 for assembling the collection device 22.

[0041] In this embodiment, the collecting device 22 is made of soft plastic material as a whole, and the negative pressure button 222 of the collecting device 22 can be set as a button with several lip-shaped folded parts (not shown). By pressing the negative pressure button 222, the pressure inside the collecting device 22 is changed, so as to achieve the purpose of sucking blood 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 flat upper part and an arc in the lower part, and the connecting port 221 of the collecting device 22 is integrally formed at a position near the upper part. After the collecting device 22 is inserted into the mounting groove 114, the connecting port 221 is docked with the negative pressure hemostasis device 2. After the blood enters the collecting device 22, it flows to the position with an arc below it by gravity. When the blood in the collecting device 22 is collected to a certain amount and taken out from the mounting groove 114, a certain height difference is maintained between the internal liquid level and the connecting port 221 to avoid leakage of the internal blood. Furthermore, a friction-enhancing member such as a rubber ring (not shown) may be provided at the position where the connection port 221 passes through the installation groove 114 to improve the installation stability of the collection device 22 .

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

[0043] It should be noted that, since the temperature of the negative pressure hemostasis device 2 is relatively high when the electrocoagulation function is turned on and it contacts the bleeding point, the length of the negative pressure hemostasis device 2 extending from the second connecting section 125 is extended to avoid damage to the optical lens 31 due to the high temperature during the hemostasis process of the negative pressure hemostasis device 2. Furthermore, it can be seen from the foregoing that in this 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 can be connected to each other, and the guide surface formed on the second connecting section 125 can further reduce the diameter of the end of the second connecting section 125, and reduce the sharp part of the second connecting section 125, so that the insertion catheter 12 drives the optical lens 31 and the negative pressure hemostasis device 2 to extend into the cavity. Furthermore, the arrangement posture of the optical fiber 32, the annular flushing channel 121, the first channel 123 and the negative pressure hemostasis device 2 in the first connecting section 124 is as shown in FIG. Figure 4 As shown, through this arrangement method, the visualization function of the endoscope assembly 3, the flushing function of the endoscope assembly 3, the blood removal and hemostasis function of the negative pressure hemostasis device 2, and the function of the first channel 123 connected to the drug delivery tube 1233 to inject medicine into the affected part are organically combined, and finally the various components formed in the handheld part 11 are connected to each other, so as to form an otolaryngology hemostasis device with perfect functions, which is suitable for most bleeding symptoms in otolaryngology. In addition, in this embodiment, the display screen 41a is assembled on the top of the handheld part 11, which further improves the compactness and convenience of the overall structure of the hemostasis device, and is suitable for places where large medical equipment is not placed. It should be noted that in this embodiment, the connecting pipe 42a can be set as a serpentine pipe or any other tubular member that is easy to bend and adjust the angle. When hemostasis is required, an external power supply is connected through the electrical connection port 118, and the affected part is directly observed at the display screen 41a to find the bleeding point.

[0044] Ginseng Fig. 9 As shown, another embodiment of the visualized ENT hemostasis device disclosed in the present invention is different from the aforementioned embodiment in that: in this embodiment, the display device 4 includes a bracket 42b and a display screen 42a mounted on the top of the bracket 42b, a clearance port 117 is provided at the bottom end of the hand-held portion 11, an electrical connection port 118 is mounted at the clearance port 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 a connecting line 43.

[0045] The difference from the above-mentioned embodiment is that the display device 4 composed of the bracket 42b and the display screen 42a in this embodiment has a larger volume, and the display screen 42a has a relatively larger display area, which can present the image of the affected part obtained by the endoscope assembly 3 at a larger magnification, and is suitable for diagnosis and treatment places with a larger space. Further, in this embodiment, the bracket 42b is selected as a foldable tripod, and the display screen 42a is assembled on the top of the bracket 42b by threaded connection or any other detachable method. The key display screen 42a is removed from the top of the bracket 42b and the bracket 42b is folded to be stored separately, which has the effect of a larger image magnification and the advantage of being easy to store and move. When in use, the display screen 42a and the electrical connection port 118 are connected by the connecting line 43 to achieve the purpose of powering the endoscope assembly 3 and the negative pressure hemostasis device 2, and the image signal is transmitted to the display screen 42a through the connecting line 43.

[0046] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention.
