Technical Field

[0001] The present invention relates to the technical field of crushers, and specifically to a uterine fibroids or uterine body rotary cutter. Background Art

[0002] As is well known, laparoscopic subtotal hysterectomy or myomectomy has been widely used clinically for many years due to its advantages such as small incisions and quick recovery. After the uterine fibroids or uterine body are removed, in order to facilitate removal from the body, a crusher is usually used to perform rotary cutting and crushing treatment on them, avoiding the long surgical incisions brought by traditional open surgery. At the same time, when using the crusher, in order to prevent the occurrence of disseminated implanted tumors, the fibroids are usually placed in a bag and then crushed to reduce the risk of debris dissemination.

[0003] However, when the existing uterine fibroids or uterine body rotary cutter is in use, the crushing knife is prone to damage the crushing bag, resulting in the leakage and scattering of fibroid cells, cell clusters or tissue fragments into the abdominal cavity, thus causing pollution and being not safe and reliable enough. At the same time, during rotary cutting and crushing, it is not easy to make the crushing knife generate extrusion force on the uterine fibroids or uterine body. Moreover, debris is easily adhered to the crushing knife, thus affecting the efficiency and effect of rotary cutting and crushing. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The uterine fibroids or uterine body rotary cutter, by setting a driving mechanism and a pushing mechanism, etc., when performing rotary cutting and pulverization, first wraps the cut uterine fibroids or uterine body with a pulverization bag and sleevs it on the side wall of the knife sheath. Then, the motor is started, and the rotation of the motor drives the rotation of the gear, thereby driving the rotation of the gear ring and the knife tube. The rotation of the knife tube drives the synchronous rotation of the pulverizing knife. At the same time, when the knife tube rotates, it drives the conical rod to rotate synchronously. When the conical rod abuts against the end of the push rod, it pushes the push rod to move away from the knife tube. At the same time, the first spring is stretched. When the conical rod passes over the end of the push rod, the fixing ring can move and reset towards the knife tube under the action of the first spring. In this way, the moving tube can reciprocate along the side wall of the fixed rod and drive the conical cover to move synchronously. When the conical cover moves away from the knife tube, it can push the uterine fibroids or uterine body to slide along the outer conical surface to between the conical cover and the knife tube. When the conical cover moves towards the knife tube, under the guiding action of the inner conical surface and the conical block, the uterine fibroids or uterine body can slide to between the inner conical surface and the conical block and abut against the pulverizing knife, so that the efficiency and effect of rotary cutting and pulverization are higher and better. At the same time, it can prevent the pulverizing knife from damaging the pulverization bag, which is safer and more reliable. And when not in use, by driving the knife tube to rotate through the driving mechanism and making the end of the conical rod abut against the end of the push rod, the conical cover can be pulled towards the knife sheath by the moving tube to seal and protect the pulverizing knife, ensuring its service effect and life.

[0016] (2) The uterine fibroids or uterine body rotary cutter, by setting a cleaning mechanism, etc., when the conical cover moves away from the knife tube, it drives the moving tube to move synchronously. At this time, a negative pressure is generated in the moving tube, and at the same time, the first one-way valve opens and the second one-way valve closes. At this time, gas enters the moving tube through the air inlet pipe. When the moving tube moves towards the knife tube with the conical cover, the gas in the moving tube can be squeezed, and its internal pressure gradually increases. When performing rotary cutting and pulverization, the conical block abuts against the end of the push pin, thereby pushing the moving block to slide into the fixed cover, aligning the through hole with the connecting pipe. At the same time, the second spring is compressed. At this time, the compressed gas in the moving tube enters the annular cover through the air supply pipe, the telescopic pipe and the connecting pipe and is ejected through the air blowing pipe, so that the pulverizing knife can be jet-cleaned to ensure its rotary cutting and pulverization efficiency and effect.

The rotation of the knife tube 103 drives the synchronous rotation of the pulverizing knife 104.

[0022] The guiding mechanism 3 includes a fixing ring 301 fixedly sleeved on the side wall of the moving tube 12.

The end of the fixed ring 301 is fixedly connected to a push rod 502. When the cutter tube 103 rotates, it drives the tapered rods 501 to rotate synchronously. When the tapered rods 501 abut against the end of the push rod 502, the push rod 502 is pushed to move away from the cutter tube 103.

[0025] The cleaning mechanism 6 includes a hollow annular cover 601 fixedly connected to the end of the cutter tube 103. A plurality of air blowing pipes 602 arranged in an array are fixedly connected to the side wall of the annular cover 601. The end of the air blowing pipe 602 is fixedly connected to a first filter screen 603.

A second one-way valve is arranged in the gas supply pipe 705, and the conduction direction of the second one-way valve is from the inside of the moving tube 12 to the inside of the annular cover 601. The other end of the gas supply pipe 705 is fixedly connected to a telescopic pipe 704. A connecting pipe 703 is fixedly connected between the other end of the telescopic pipe 704 and the annular cover 601. An opening and closing mechanism 8 is arranged on the side wall of the connecting pipe 703. When the conical cover 15 moves away from the cutter tube 103, it drives the moving tube 12 to move synchronously. At this time, a negative pressure is generated inside the moving tube 12. At the same time, the first one-way valve opens and the second one-way valve closes. At this time, gas enters the moving tube 12 through the air inlet pipe 701. When the moving tube 12 moves towards the cutter tube 103 along with the conical cover 15, the gas inside the moving tube 12 can be squeezed, making the internal pressure gradually increase. During rotary cutting and pulverizing, the opening and closing mechanism 8 opens. At this time, the compressed gas inside the moving tube 12 enters the annular cover 601 through the gas supply pipe 705, the telescopic pipe 704, and the connecting pipe 703 and is ejected through the air blowing pipes 602.

[0027] The opening and closing mechanism 8 is fixedly inserted into the fixed cover 801 on the side wall of the connecting pipe 703.

[0028] The second reset mechanism 9 includes two symmetrically arranged first connection blocks 901 fixedly connected to the side wall of the moving block 802. A T-shaped guide rod 902 is fixedly connected to the side wall of each first connection block 901. A second connection block 903 is sleeved on the side wall of each T-shaped guide rod 902, and the second connection block 903 is fixed to the side wall of the fixed cover 801.

[0029] The installation mechanism 10 includes two symmetrically arranged jacks 1001 opened on the side wall of the L-shaped plate 11. Bolts 1002 are inserted into the jacks 1001, and the bolts 1002 are detachably connected to the handle 101. After pulverization is completed, the bolts 1002 are unscrewed from the handle 101. Then, the cutter tube 103 and the like are taken out integrally through the L-shaped plate 11. Then, the absorption tube is inserted into the pulverization bag 105 through the knife sheath 102 to absorb the pulverized debris.

[0030] Working principle: When in use, during rotary cutting and pulverization, first, the cut uterine fibroids or uterine body are wrapped by the pulverization bag 105 and sleeved on the side wall of the knife sheath 102. Then, the motor 203 is started. The rotation of the motor 203 drives the rotation of the gear 204, thereby driving the rotation of the gear ring 201 and the cutter tube 103. The rotation of the cutter tube 103 drives the synchronous rotation of the pulverizing knife 104. At the same time, when the cutter tube 103 rotates, it drives the conical rod 501 to rotate synchronously. When the conical rod 501 abuts against the end of the push rod 502, it pushes the push rod 502 to move away from the cutter tube 103. At the same time, the first spring 402 is stretched. When the conical rod 501 passes over the end of the push rod 502, the fixed ring 301 can move and reset towards the cutter tube 103 under the action of the first spring 402. In this way, the moving tube 12 can reciprocally move along the side wall of the fixed rod 13 and drive the conical cover 15 to move synchronously; When the conical cover 15 moves away from the cutter tube 103, it can push the uterine fibroids or uterine body to slide along the outer conical surface 1501 to between the conical cover 15 and the cutter tube 103. When the conical cover 15 moves towards the cutter tube 103, under the guiding action of the inner conical surface 1502 and the conical block 16, the uterine fibroids or uterine body can slide to between the inner conical surface 1502 and the conical block 16 and abut against the cutting knife 104, so that the efficiency and effect of rotary cutting and comminution are higher. At the same time, it can avoid damage to the comminution bag 105 by the cutting knife 104, which is safer and more reliable; When the conical cover 15 moves away from the cutter tube 103, it drives the moving tube 12 to move synchronously. At this time, a negative pressure is generated in the moving tube 12. At the same time, the first one-way valve opens and the second one-way valve closes. At this time, gas enters the moving tube 12 through the air inlet pipe 701. When the moving tube 12 moves towards the cutter tube 103 along with the conical cover 15, the gas in the moving tube 12 can be squeezed, and its internal pressure gradually increases. During rotary cutting and comminution, the conical block 16 abuts against the end of the push pin 804, thereby pushing the moving block 802 to slide into the fixed cover 801, making the through hole 803 align with the connecting pipe 703. At the same time, the second spring 904 is compressed. At this time, the compressed gas in the moving tube 12 enters the annular cover 601 through the air supply pipe 705, the telescopic pipe 704 and the connecting pipe 703 and is ejected through the air blowing pipe 602, so that the cutting knife 104 can be cleaned by jetting, ensuring its rotary cutting and comminution efficiency and effect; After the comminution is completed, the bolt 1002 is unscrewed from the handle 101. Then, the cutter tube 103 and the like are taken out integrally through the L-shaped plate 11. Then, the absorption tube is inserted into the comminution bag 105 through the knife sheath 102 to absorb the comminuted debris; In another embodiment, in the case of not performing surgery on uterine fibroids, it is possible to puncture into the fibroids under ultrasonic guidance, cut the fibroids, and aspirate the tissue. By this method, the uterine fibroids are reduced, avoiding open surgery; Moreover, when not in use, the driving mechanism 2 drives the cutter tube 103 to rotate, and the end of the conical rod 501 abuts against the end of the push rod 502, so that the conical cover 15 can be pulled towards the knife sheath 102 by the moving tube 12 to seal and protect the cutting knife 104, ensuring its use effect and service life.
