Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a hysteroscopic imaging device with automatic anti-fog function. Background Technology

[0002] Hysteroscopy is a new, minimally invasive gynecological diagnostic and treatment technique. It is a fiber optic endoscope used for examination and treatment within the uterine cavity, comprising a hysteroscope, energy system, light source system, irrigation system, and imaging system. It utilizes the anterior part of the endoscope to enter the uterine cavity, providing magnification of the observed area. Its direct and accurate visualization makes it the preferred examination method for gynecological bleeding disorders and intrauterine lesions. It is suitable for abnormal uterine bleeding before and after menopause; abnormal sonographic findings in the uterine cavity; diagnosis or determination of whether submucosal fibroids or endometrial polyps can be removed transcervically; exploration of the cervical canal and / or intrauterine factors in infertility, recurrent miscarriage, and failed pregnancy; oligomenorrhea or amenorrhea; location or attempted removal of a lost intrauterine device; diagnosis of uterine cavity malformations and intrauterine adhesions, and attempted separation, etc.

[0003] Currently, conventional hysteroscopes mostly use traditional electric heating methods when fogging occurs on the lens, which can easily lead to local overheating or uneven temperature, causing condensation on the lens or patient discomfort. At the same time, existing technologies are not convenient for lens disassembly, which can easily lead to difficulties in structural maintenance. To address the above problems, this paper provides a hysteroscopic imaging device with an automatic anti-fog function. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hysteroscopic imaging device with automatic anti-fog function, which aims to improve the problems of poor defogging method and inconvenient disassembly in the existing hysteroscopy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hysteroscopic imaging device with automatic anti-fog function, comprising a hysteroscopic body, a handle at the bottom of the hysteroscopic body, an end cap at the front end of the hysteroscopic body, a scope tube at the front end of the end cap, a lens sleeved at the front end of the scope tube, a quick-release mechanism on the surface of the scope tube corresponding to the lens, and an air blowing device at the bottom of the scope tube.

[0006] As a further description of the above technical solution:

[0007] The quick-release mechanism includes a button embedded in the surface of the endoscope tube, the button extending into the inner surface of the endoscope tube and fitted with a spring rod, a support block inserted into the bottom of the spring rod, a locking rod vertically slidably connected to one side of the support block, and a U-shaped component being locked in place by an L-shaped structure.

[0008] As a further description of the above technical solution:

[0009] The bottom end of the U-shaped component is fixedly connected to a plug, which is located at the back end of the lens.

[0010] As a further description of the above technical solution:

[0011] The blowing device includes a miniature air pump, the output end of which is connected to an air outlet pipe. One end of the air outlet pipe extends into the interior of the end head and is connected to a diverter pipe. The diverter pipe extends through the inner wall layer of the lens tube to an air inlet. One end of the air inlet is connected to a guide sleeve. The surface of the guide sleeve is provided with a spiral guide groove, and the spiral guide groove is aligned with the lens.

[0012] As a further description of the above technical solution:

[0013] The bottom of the miniature air pump is equipped with a support plate, which is composed of a vertical plate and a horizontal plate. The support plate is fixedly connected to the main body of the hysteroscope through the vertical plate.

[0014] As a further description of the above technical solution:

[0015] The bottom of the hysteroscope body is connected to a beam guide interface, and the tail end of the hysteroscope body is provided with an eyepiece installed by screws.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, an air blowing device is installed, and a micro air pump is activated to transmit pressurized air through the air outlet pipe to the splitter pipe. The air is then output through the splitter pipe along both sides of the inner wall of the lens tube to the air inlet. The air is then concentrated and input into the guide sleeve through the air inlet, and the air is evenly blown towards the lens through the spiral guide groove. Compared with traditional electric heating, this invention can solve the problems of local overheating or uneven temperature. By pressing the button of the quick-release mechanism, the spring rod moves downward. The spring rod passes through the support block and drives the locking rod downward, causing the locking rod to disengage from the U-shaped part, thereby allowing the lens to be quickly removed for replacement and repair.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1-5 An embodiment of this utility model is provided: a hysteroscopic imaging device with automatic anti-fog function, including a hysteroscopic body 1, a handle 2 provided at the bottom of the hysteroscopic body 1, an end 3 provided at the front end of the hysteroscopic body 1, a tube 4 provided at the front end of the end 3, a lens 5 sleeved at the front end of the tube 4, a quick release mechanism 6 provided on the surface of the tube 4 corresponding to the lens 5, and an air blowing device 7 provided at the bottom of the tube 4.

[0027] The quick-release mechanism 6 includes a button 601 embedded in the surface of the lens tube 4. The button 601 extends into the inner surface of the lens tube 4 and is fitted with a spring rod 602. A support block 603 is inserted into the bottom of the spring rod 602. A locking rod 604 is vertically slidably connected to one side of the support block 603. The locking rod 604 is locked with a U-shaped piece 605 through an L-shaped structure.

[0028] The bottom of the U-shaped part 605 is fixedly connected to the plug 8, which is located on the back of the lens 5.

[0029] The air blowing device 7 includes a miniature air pump 701. The output end of the miniature air pump 701 is connected to an air outlet pipe 702. One end of the air outlet pipe 702 extends into the interior of the end head 3 and is connected to a diverter pipe 703. The diverter pipe 703 extends through the inner wall layer of the lens tube 4 to an air inlet 704. One end of the air inlet 704 is connected to a guide sleeve 705. A spiral guide groove 706 is formed on the surface of the guide sleeve 705, and the spiral guide groove 706 is aligned with the lens 5.

[0030] The bottom of the miniature air pump 701 is equipped with a support plate 11, which is composed of a vertical plate and a horizontal plate. The support plate 11 is fixedly connected to the hysteroscope body 1 through the vertical plate.

[0031] The bottom of the hysteroscope body 1 is connected to a beam guide interface 9, and the tail end of the hysteroscope body 1 is provided with an eyepiece 10 which is screwed on.

[0032] Specifically, the hysteroscope body 1 is held by the handle 2, connected to the hysteroscope body 1 via the beam guide interface 9, and connected to the hysteroscope body 1 via an external display device. The end 3 fixes the end tube 4, which is then inserted into the patient's vagina and enters the uterus through the cervix. The lens 5 at the front end penetrates the lesion site to perform corresponding surgical operations, such as resection or biopsy. The lens 5 can be quickly detached via the quick-release mechanism 6. Pressing the button 601 moves the spring rod 602 downwards simultaneously. The support block 603 drives the locking rod 604 to move downward, so that the end of the locking rod 604 is separated from the U-shaped part 605, thereby removing the lens 5 from the front end of the lens tube 4. By setting the air blowing device 7 to start the micro air pump 701, pressurized air is transmitted through the air outlet pipe 702 to the diverter pipe 703. Then, through the diverter pipe 703 and the air inlet 704, it is transmitted to the guide sleeve 705 for collection. The air is evenly delivered to each corner of the lens 5 through the spiral guide groove 706. The dry airflow is guided to the lens surface to form an air curtain to isolate moisture and achieve safe, stable and uniform defogging.

[0033] Working principle: In use, the beam guide structure 9 is connected to the beam guide, and the hysteroscope body 1 is connected to the external monitor. The lens 5 is installed at the front end of the endoscope tube 4 and inserted. By pressing the button 601, the locking rod 604 is moved down. After the U-shaped part 605 moves to the appropriate position, the button 601 is released, and the spring rod 602 drives the locking rod 604 to be fixedly engaged inside the U-shaped part 605 to complete the fixed assembly. The handle 2 is manually held to drive the endoscope tube 4 into the patient's vagina, through the cervix into the uterus, and through the lens 5 at the front end to penetrate the lesion. When defogging is required, the micro air pump 701 is started by the external power supply. The micro air pump 701 generates a certain amount of pressurized air and outputs it to the inside of the guide sleeve 705 through the air outlet 702, the diverter 703 and the air inlet 704. The spiral guide groove 706 blows the air evenly towards the lens 5 to achieve the defogging effect.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
