Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a suction type uterine fibroid remover. Background Art
[0002] Uterine fibroids are common benign tumors in the female reproductive system. Minimally invasive surgery has become one of the main means of treating uterine fibroids. During minimally invasive surgery, doctors usually rely on mechanical tools such as fibroid forceps and scrapers to remove fibroid tissue in batches. However, these traditional instruments have many limitations in actual applications, especially when dealing with scattered small fibroid fragments.
[0003] First, existing mechanical tools such as myoma forceps and curettes are mainly used to grab or scrape larger myoma tissues. These instruments are often difficult to completely remove small pieces of myoma debris produced by cutting or separation during surgery. This incomplete cleaning may cause residual tissue to cause postoperative complications, such as local inflammation or recurrent myoma growth. Secondly, because traditional instruments cannot completely remove myoma tissue in one go, doctors need to move the instruments in and out of the patient's body multiple times to gradually remove the residue. This process not only prolongs the operation time, but also increases the risk of intraoperative infection. Each time the instrument enters and exits the uterine cavity, it may bring foreign bacteria into the body, thereby threatening the patient's health and safety. In addition, the frequent movement and friction of the instrument in the uterine cavity may irritate or damage the endometrium and other adjacent tissues, resulting in a prolonged postoperative recovery period. Summary of the invention
[0004] In view of this, the present invention provides a suction-type uterine fibroid remover, which can overcome the disadvantages of traditional instruments that when used, doctors need to insert and exit the instrument in the patient's body multiple times to gradually remove residues. This process not only prolongs the operation time, but also increases the risk of infection and stimulates or damages the endometrium and other adjacent tissues.

[0006] As a preferred technical solution of the present invention, the inflation component includes: an air pump installed inside the mounting shell; a connecting pipe connected to the air outlet of the air pump and maintained in communication, and the end of the connecting pipe away from the air pump is connected to the hose and maintained in communication.
[0007] As a preferred technical solution of the present invention, the adjustment component includes: a guide rod, which is slidably connected to the inside of the insert tube at circumferential intervals; a contact plate, which is connected to the end of the guide rod; a wire rope, which is slidably connected to the inside of the insert tube at circumferential intervals, and one end of the wire rope is connected to the side of the contact plate, and the other end of the wire rope is connected to the side of the connecting ring; a mounting sleeve, which is mounted on the outer wall of the insert tube; a pressure plate, which is connected to the side of the mounting sleeve; and a limiting mechanism, which is arranged on the insert tube and is used to limit the mounting sleeve.
[0008] As a preferred technical solution of the present invention, the limiting mechanism includes: a clamping rod, which is symmetrically slidably connected to the inside of the installation sleeve, and the outer wall of the insert tube is symmetrically circumferentially spaced with clamping grooves, and the end of the clamping rod is clamped in the clamping groove to limit the installation sleeve; a reset spring, connecting the clamping rod and the installation sleeve.
[0009] As a preferred technical solution of the present invention, the limiting mechanism also includes: two rubber membranes, the two ends of the rubber membranes are respectively connected to the insertion tube and the connecting ring, and the wire rope and the connecting spring are both located between the two rubber membranes.
[0010] As a preferred technical solution of the present invention, it also includes: a connecting frame connected to the insertion tube; a display screen installed on the top of the connecting frame; a camera installed on the side of the connecting ring away from the connecting spring; and a lighting lamp symmetrically connected to the side of the connecting ring away from the connecting spring.
[0011] As a preferred technical solution of the present invention, it also includes: a rubber ring connected to the side of the contact plate away from the guide rod, and the pressure plate is in contact with the rubber ring.

[0013] Beneficial effects: 1. The present invention can effectively solve the problem of low efficiency of traditional instruments in handling small pieces of fibroid debris through the coordinated work of the diaphragm and the vacuum pump. After inflation, the diaphragm can reduce the diameter of the internal space of the hose and the cannula, so that the suction force is concentrated in the middle area, thereby ensuring that smaller uterine fibroids can be accurately sucked in and transported to the collection tube. This design can not only improve the thoroughness of surgical cleaning, but also reduce the risk of postoperative complications caused by residual tissue.
[0014] 2. The present invention uses the function of the adjustment component to flexibly adjust the angle of the connecting ring to adapt to uterine fibroids in different positions. By rotating the mounting sleeve, the pressure plate squeezes different parts of the rubber ring, driving the contact plate and the wire rope to move, thereby accurately controlling the tilt direction of the connecting ring. The doctor does not need to frequently change or reposition the instrument, and can complete the removal operation of fibroids in different positions at one time, which greatly shortens the operation time and reduces the infection risk caused by the entry and exit of the instrument.
[0015] 3. The present invention can provide doctors with clear real-time images of the interior of the uterus through the combined use of a camera, a lighting lamp and a display screen, allowing doctors to clearly observe the internal conditions of the uterus and accurately control the operating range and strength of the instrument. This design can not only reduce unnecessary contact between the instrument and the endometrium, but also avoid misoperation caused by unclear vision, thereby effectively protecting the endometrium and other adjacent tissues and promoting the patient's postoperative recovery.

The inflation component is used to inflate the above-mentioned cavity, and the adjustment component is used to adjust the angle of the connecting ring 7.
[0032] like Figure 4 As shown, the inflation component includes an air pump 11 and a connecting pipe 12. The air pump 11 is installed inside the mounting shell 1, and the air pump 11 is located on the rear side of the vacuum pump 8. The air outlet of the air pump 11 is connected to the connecting pipe 12 and maintained in communication. The end of the connecting pipe 12 away from the air pump 11 is connected to the hose 4 and maintained in communication.
[0033] like Figure 5-Figure 7As shown, the adjustment component includes a guide rod 13, a contact plate 14, a wire rope 15, a mounting sleeve 16, a pressure plate 17 and a limiting mechanism. A plurality of guide rods 13 are slidably connected to the right side of the insert tube 5 at circumferential intervals. The left end of each guide rod 13 is connected to a contact plate 14. A plurality of wire ropes 15 are slidably connected to the insert tube 5 at circumferential intervals. The wire ropes 15 correspond to the contact plates 14 one by one, and the right ends of the wire ropes 15 are fixedly connected to the left sides of the corresponding contact plates 14. The left ends of the wire ropes 15 are connected to the right side of the connecting ring 7. A mounting sleeve 16 is sleeved on the right side of the outer wall of the insert tube 5, and a pressure plate 17 is connected to the right side of the mounting sleeve 16. The right side surface of the pressure plate 17 is an arc surface. The limiting mechanism includes a clamping rod 19, A reset spring 20 and a rubber membrane 21, a clamping rod 19 is symmetrically slidably connected to the inside of the installation sleeve 16, and the ends of the two clamping rods 19 that are close to each other are both arc surfaces, and the outer wall of the insert tube 5 is symmetrically circumferentially spaced with two circles of clamping grooves 18, and the ends of the two clamping rods 19 that are close to each other are both clamped in the clamping grooves 18 to limit the installation sleeve 16, and a reset spring 20 is connected between the ends of the two clamping rods 19 that are away from each other and the installation sleeve 16, two rubber membranes 21 are connected to the left side of the insert tube 5 and the right side of the connecting ring 7, and the connecting spring 6 and the wire rope 15 are both located between the two rubber membranes 21 to protect the connecting spring 6 and the wire rope 15 and prevent the connecting spring 6 and the wire rope 15 from being contaminated.
[0034] like Figure 8 and Fig. 9 As shown, it also includes a connecting frame 22, a display screen 23, a camera 24 and a lighting lamp 25.

[0035] like Figure 5 As shown, a rubber ring 26 is also included. The rubber ring 26 is connected between the left sides of multiple contact plates 14, and the inclined surface on the right side of the pressure plate 17 contacts the left side of the rubber ring 26. The rubber ring 26 can prevent the inclined surface on the right side of the pressure plate 17 from directly contacting the contact plate 14, so that the pressure plate 17 can rotate more smoothly and reduce the wear between the pressure plate 17 and the contact plate 14.
[0036] like Fig.10 As shown, a protective sleeve 27 is also included. The right side of the outer wall of the insertion tube 5 is provided with the protective sleeve 27, and the left side of the protective sleeve 27 is connected to the right side of the installation sleeve 16. The guide rod 13, the contact plate 14 and the rubber ring 26 are located inside the protective sleeve 27, thereby preventing the guide rod 13, the contact plate 14 and the rubber ring 26 from being contaminated, and also preventing the contact plate 14 from being accidentally touched.
[0037] Initially, the end of the clamping rod 19 is clamped in the clamping slot 18 on the left; first, the device is placed in the designated position, and then the air pump 11 is controlled by the controller 2 to start working. The air pump 11 can inflate the cavity between the outer wall of the diaphragm 10 and the inner wall of the hose 4, the inner wall of the cannula 5 and the inner wall of the connecting ring 7 through the connecting pipe 12, so that the diaphragm 10 is in a bulging state inside the hose 4 and the cannula 5, thereby reducing the diameter of the internal space of the hose 4 and the internal space of the cannula 5; then the doctor can hold the cannula 5, insert the connecting ring 7 and the cannula 5 into the patient's uterus, and at the same time, the display screen 23, the camera 24 and the lighting lamp 25 can be controlled by the controller 2 to start working. The lighting lamp 25 can illuminate the inside of the patient's uterus, and the camera 24 can take pictures of the inside of the patient's uterus and upload the pictures to the display screen 23 for display. Then, the vacuum pump 8 can be controlled by the controller 2 to start working, and the vacuum pump 8 can extract the air inside the collection tube 3 and the inside of the diaphragm 10 through the exhaust pipe 9. Air, thereby generating suction at the left end of the connecting ring 7. By controlling the connecting ring 7 to approach the uterine fibroids, the uterine fibroids can be sucked into the inner side of the diaphragm 10 by the doctor, and the uterine fibroids can be dropped into the collecting tube 3 along the inner side of the diaphragm 10; when the volume of the uterine fibroids is small, the diaphragm 10 can block most of the space inside the hose 4 and the cannula 5, so that the suction can be concentrated in the middle position between the hose 4 and the cannula 5, ensuring that the uterine fibroids with a small volume can be accurately transported to the inside of the collecting tube 3 (if there is no diaphragm 10, the uterine fibroids with a small volume cannot be subjected to sufficient suction, and the connecting ring 7 will suck the air inside the patient's uterus into the collecting tube 3, resulting in the uterine fibroids with a small volume being unable to smoothly reach the inside of the collecting tube 3); when the volume of the uterine fibroids is large, since the material of the diaphragm 10 is relatively soft, the diaphragm 10 can be locally deformed by the squeezing of the uterine fibroids, which will not affect the movement of the uterine fibroids inside the hose 4 and the cannula 5, thereby ensuring that the uterine fibroids with a large volume can be accurately transported to the inside of the collecting tube 3;When the angle of the connecting ring 7 needs to be adjusted, the installation sleeve 16 can be pushed to the right, and the installation sleeve 16 can drive the clamping rod 19 to move to the right. Under the action of the return spring 20, the end of the clamping rod 19 can be disengaged from the clamping groove 18 on the left and clamped in the clamping groove 18 on the right. At the same time, the installation sleeve 16 will drive the pressure plate 17 to move to the right, and the pressure plate 17 will squeeze the rubber ring 26, so that the compressed part of the rubber ring 26 can move to the right and deform. The rubber ring 26 can drive part of the contact plate 14 to move to the right, and the contact plate 14 will drive the corresponding steel wire rope 15 to move to the right. The wire rope 15 can pull a part of the connecting ring 7 to move to the right, while the rest of the contact plate 14 and the wire rope 15 remain stationary, and the rest of the connecting ring 7 also remains stationary, so that the connecting ring 7 is tilted, and a part of the connecting spring 6 will be compressed. When it is necessary to adjust the tilt position of the connecting ring 7, it is only necessary to rotate the mounting sleeve 16. The mounting sleeve 16 can drive the pressure plate 17 to rotate, so that the pressure plate 17 squeezes different parts of the rubber ring 26, thereby driving the contact plates 14 and the wire rope 15 at different positions to move to the right, and at this time, the direction of the pressure on the connecting spring 6 also changes accordingly. , and the contact plate 14 which is not under pressure will relax the wire rope 15, so that the wire rope 15 will no longer apply tension to the connecting ring 7, so that the part of the connecting spring 6 which is not under pressure will return to its original state, so that the connecting ring 7 can be tilted in different directions, so that the connecting ring 7 can suck out all the uterine fibroids in the patient's uterus at one time. When the uterine fibroids are all sucked out, the doctor needs to take out the connecting ring 7 and the cannula 5 from the patient's uterus, and then control the vacuum pump 8 to stop working through the controller 2, and control the air pump 11 to connect the outer wall of the diaphragm 10 with the inner wall of the hose 4 and the cannula through the connecting pipe 12. 5 and the inner wall of the connecting ring 7, the air in the cavity between them is extracted to restore the diaphragm 10, which is convenient for the subsequent cleaning work. Then the installation sleeve 16 is moved to the left to reset, so that the end of the clamping rod 19 is clamped in the left clamping groove 18 again, and the installation sleeve 16 can drive the pressing plate 17 to move to the left to reset, so that the pressing plate 17 no longer squeezes the rubber ring 26. At this time, the connecting spring 6 can completely restore to its original state, driving the connecting ring 7 to rotate back to the initial state, and then the collecting tube 3 can be rotated to separate the collecting tube 3 from the installation shell 1, and then the uterine fibroids in the collecting tube 3 can be uniformly treated. ;
[0038] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
