[0001] The invention belongs to the technical field of surgical specimen collection and relates to a hysteroscopic micro-specimen collector. Background Art

[0002] Hysteroscopy is a minimally invasive gynecological diagnosis and treatment technology used for intrauterine examination and treatment. The hysteroscope includes the hysteroscope itself, energy system, light source system, perfusion system and imaging system. It uses the front part of the scope to enter the uterine cavity, which has a magnifying effect on the observed part, so that the internal situation of the uterine cavity can be observed intuitively and accurately. This technology usually uses a slender optical fiber glass speculum with a diameter of about 3 to 4 mm, which enters the uterine cavity through the vagina to directly observe the female cervix and the inside of the uterus to check whether there are lesions, and can directly sample the lesion tissue for subsequent pathological examination.

[0003] At present, during hysteroscopic surgery, if there is a specimen, it can be removed from the uterine cavity by instruments. However, when using instruments to remove the specimen, if the specimen is large, it can be removed normally. However, if the specimen is small, medical staff are required to hold gauze to receive the specimen. Moreover, when a small specimen passes through the cervical opening or the hysteroscope drainage port, it is easily washed out by water, which may cause the specimen to flow away with the water and lead to the loss of the specimen.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] A hysteroscopic micro-specimen collector, such as Figure 1-Figure 4 As shown, it includes a hysteroscope sheath 1, a docking tube 2, a drainage pipe 3 and a filtering mechanism. A docking tube 2 is provided at the water outlet of the hysteroscope sheath 1 so that the water discharged when the hysteroscope sheath 1 is extended into the patient's vagina will enter the docking tube 2, and the collected diseased tissue will also enter the docking tube 2. The bottom of the docking tube 2 is spliced ​​with a drainage pipe 3, and the docking tube 2 is provided with a filtering mechanism.

[0028] like Figure 3and Figure 4 As shown, the filtering mechanism includes a mounting block 41, a fixing ring 42, a specimen collection net 43 and a locking rod 44. The mounting block 41 is clamped with a fixing ring 42, and the specimen collection net 43 is clamped at the lower part of the fixing ring 42. An insertion port is provided on the right side of the lower part of the docking pipe 2. The mounting block 41 and the fixing ring 42 can be inserted into the insertion port, so that the specimen collection net 43 is located below the fixing ring 42. The specimen entering the docking pipe 2 will be blocked by the specimen collection net 43, and the water will directly pass through the specimen collection net 43 and be discharged through the sewage pipe 3, thereby achieving the effect of collecting the specimens. The lower part of the mounting block 41 is rotatably connected with a locking rod 44, and the specimen collection net 43 can be plugged into the locking rod 44. A plug hole is provided on the docking pipe 2, and the locking rod 44 can be inserted into the plug hole of the docking pipe 2 to fix the specimen collection net 43 through the locking rod 44 and the docking pipe 2.

[0029] When the uterine cavity of the patient is examined by hysteroscopy, the collector can be used to collect samples taken during the examination. During the examination, the hysteroscope sheath 1 is inserted into the uterine cavity of the patient through the vagina to directly observe the female's cervix and the inside of the uterus to check whether there are lesions. During the inspection, if there are lesions, the diseased tissue can be directly sampled, and the sampled diseased tissue will enter the hysteroscope sheath 1. At the same time, water will also enter the hysteroscope sheath 1. The water and diseased tissue that enter the hysteroscope sheath 1 will fall into the docking tube 2. The water will directly pass through the specimen collection net 43 and be discharged, while the diseased tissue will be blocked by the specimen collection net 43, so that the specimen collection net 43 can collect the diseased tissue. After the examination is completed, when the diseased tissue needs to be removed, the hysteroscope sheath 1 can be removed first, and then the mounting block 41 is removed, so that the fixing ring 42 and the specimen collection net 43 are taken out from the butt joint 2, and the locking card rod 44 can be operated to rotate at this time, and the locking card rod 44 can drive the specimen collection net 43 to rotate when rotating. Before that, the collection frame can be placed under the specimen collection net 43, and the rotation of the specimen collection net 43 can dump the diseased tissue thereon to the collection frame, and the diseased tissue is collected by the collection frame. When re-examination is needed, the fixing ring 42 and the specimen collection net 43 can be removed, and then a new fixing ring 42 and the specimen collection net 43 are replaced, and the mounting block 41 is fixed to the butt joint 2, and then the uterine cavity of the next patient can be inspected. In this way, the present device can be used to inspect the patient's uterine cavity, and during the inspection, the diseased tissue can be collected to avoid the loss of small pieces of diseased tissue.

[0030] like Figure 5As shown, an automatic flipping mechanism is also included, which includes a transmission rod 51 and an elastic member 52. The transmission rod 51 is connected to the locking rod 44, and an elastic member 52 is connected between the locking rod 44 and the mounting block 41. The elastic member 52 is a torsion spring.

[0031] When the fixing ring 42 is installed in the butt joint 2 and the locking rod 44 is inserted into the mounting block 41, the elastic member 52 is in a deformed state. After the mounting block 41, the fixing ring 42 and the specimen collecting net 43 are completely removed, the locking rod 44 is also separated from the butt joint 2. At this time, the locking rod 44 rotates under the action of the elastic member 52, and the rotation of the locking rod 44 drives the specimen collecting net 43 to rotate. In this way, the effect of automatically driving the specimen collecting net 43 to rotate can be achieved. Before inserting the fixing ring 42 and the mounting block 41, the locking rod 44 can be rotated in the opposite direction to reset it.

[0032] like Figure 6 As shown, it also includes an extrusion mechanism, which includes a support bracket 61, a sliding rod 62, an extension pull plate 63, an extrusion cam 64 and a guide sliding column 65. The mounting block 41 is connected to the support bracket 61, and the upper part of the support bracket 61 is slidably connected to the sliding rod 62, and the sliding rod 62 can slide left and right along the support bracket 61. The front and rear ends of the sliding rod 62 are connected to the extension pull plates 63, and the sliding rod 62 is pulled to move by the extension pull plates 63, which is more convenient during operation. The middle of the sliding rod 62 is connected to a guide sliding column 65, and the guide sliding column 65 is slidably connected to the mounting block 41. The movement of the sliding rod 62 can be guided by the guide sliding column 65 and the mounting block 41. The bottom of the guide sliding column 65 is connected to the extrusion cam 64, and a spiral groove 66 is opened on the transmission rod 51. The extrusion cam 64 is located in the spiral groove 66, so that the extrusion cam 64 can squeeze the spiral groove 66 when moving, thereby driving the transmission rod 51 to rotate.

[0033] After the mounting block 41 is taken out, the transmission pull rod 51 is separated from the butt joint tube 2. At this time, the locking lever 44 and the transmission pull rod 51 will rotate under the action of the elastic member 52. When the transmission pull rod 51 rotates, it will drive the extrusion cam 64 to move to the right through the spiral groove 66 thereon. When the extrusion cam 64 moves, it will drive the sliding rod 62 and the guide sliding column 65 to move to the right. After the mounting block 41 and the fixed collar 42 are inserted into the butt joint tube 2, the extension pull plate 63 can be pushed to move to the left. When the extension pull plate 63 moves, it drives the sliding rod 62 to move together. When the sliding rod 62 moves, it drives the guide sliding column 65 to move. The guide sliding column 65 When moving, it drives the extrusion cam 64 to move. When moving, the extrusion cam 64 will move along the spiral groove 66, so that the extrusion spiral groove 66 drives the transmission pull rod 51 to rotate, and the rotation of the transmission pull rod 51 drives the locking card rod 44 to rotate, and the elastic member 52 is deformed. After the locking card rod 44 has completed its rotation, the extrusion cam 64 also moves to the end of the spiral groove 66. At this time, continuing to push the extension pull plate 63 to drive the sliding rod 62 to move can enable the extrusion cam 64 to continue to squeeze the transmission pull rod 51 to move to the left, thereby driving the locking card rod 44 to insert into the docking tube 2. In this way, there is no need to manually operate the rotation of the transmission pull rod 51, and the operation is more convenient.

[0034] like Figure 7 and Figure 8 As shown, a cleaning mechanism is also included, which includes an annular pipe 71, a flushing nozzle 72, a liquid transmission pipe 73 and a spray tank 74. The upper part of the fixed ring 42 is connected to the annular pipe 71, and a plurality of flushing nozzles 72 are evenly installed in the annular pipe 71. A spray tank 74 is provided on the support frame 61, and a liquid transmission pipe 73 is connected between the liquid outlet end of the spray tank 74 and the annular pipe 71, so that the liquid sprayed from the spray tank 74 will be injected into the annular pipe 71 through the liquid transmission pipe 73, and finally sprayed out through the flushing nozzle 72.

[0035] During the process of flipping the specimen collection net 43, there may be diseased tissue hanging on the specimen collection net 43. At this time, the spray tank 74 can be controlled to start injecting liquid into the annular pipe 71 through the liquid transmission pipe 73. The injected liquid will be sprayed out through the flushing nozzle 72, thereby spraying the liquid on the specimen collection net 43, flushing off the diseased tissue hanging on the specimen collection net 43, and preventing the diseased tissue from adhering to the specimen collection net 43.

[0036] like Fig. 9 and Fig.10As shown, a positioning pin 8 is also included. A plurality of equally spaced sockets are provided on the right side of the butt joint pipe 2 and the right side of the mounting block 41. The sockets cooperate with the positioning pin 8, and the positioning pin 8 can be accurately inserted between the corresponding sockets of the butt joint pipe 2 and the mounting block 41, thereby firmly fixing the butt joint pipe 2 and the mounting block 41, effectively preventing the relative displacement or loosening of the two during use. The positioning pin 8 is made of high-strength alloy steel and has excellent wear resistance and shear resistance.

[0037] like Fig. 9 As shown, a damping ring 9 is also included. The damping ring 9 is precisely installed in the annular groove between the guide sliding column 65 and the mounting block 41, and an interference fit is used to ensure the installation stability. The friction resistance generated by the contact surface that evenly fits the guide sliding column 65 and the mounting block 41 can reduce the sliding speed of the guide sliding column 65, ensure that the specimen collection net 43 flips smoothly and reliably, and avoids flipping too quickly. The damping ring 9 is made of high-performance polyurethane material and has good wear resistance, elastic recovery performance, and high temperature resistance and corrosion resistance.
