Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a tumor resection device and a tumor resection method thereof. Background Technology

[0002] In existing tumor resection surgeries, medical staff use scalpels or forceps and other medical instruments to perform the surgery, such as the scalpel for tumor resection disclosed in patent number 201120497997.8 and the forceps for tumor resection disclosed in patent number 202220795692.3. During the surgery, the tumor is first cut to separate it from the surrounding healthy tissue, and then the removed tumor is removed using forceps or similar instruments. Existing tumor resection surgeries require the use of multiple surgical instruments such as forceps and scalpels, which cannot meet the needs of minimally invasive surgery. Furthermore, after the tumor is removed, it needs to be removed with forceps, and multiple tumors often need to be removed during tumor resection surgery. Repeatedly removing the removed tumor from the wound increases the patient's pain. Therefore, this invention designs a novel tumor resection device. The resection mechanism of this invention uses an adsorption mechanism to remove the removed tumor, effectively reducing the wound size, alleviating patient pain, and lowering surgical risks. Summary of the Invention

[0016] The tailstock is divided into three independent sections, with the first through hole, the second through hole, and the third through hole located on the three sections of the tailstock respectively. The tailstock is movably mounted to the handle, and the tailstock is movable relative to the handle.

[0024] 1. During tumor resection surgery, medical staff hold the handle, insert the resection mechanism into the wound, and move it to the tumor resection position. The drive mechanism drives the resection mechanism to perform the resection. At the same time, while the resection mechanism is removing the tumor, the suction mechanism removes the removed tumor. This eliminates the problem of large wounds caused by the use of multiple surgical instruments such as surgical forceps and scalpels to remove tumors, which cannot meet the requirements of minimally invasive surgery and increases patient pain. The present invention removes the tumor at the same time as it is removed, which is not only simple and convenient to operate, but also effectively reduces the wound and alleviates patient pain.

[0025] 2. This invention adjusts the size of the conical structure formed by multiple first and second elastic blades based on the degree of extension and retraction of the telescopic shaft, adapting to the needs of different tumor resection situations. It has a wide range of applications and is flexible and convenient to use. Furthermore, the multiple first and second elastic blades rotate in opposite directions, which counteracts the force on the handle, making it easier for medical personnel to operate.

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0039] Example

[0040] Reference Figure 1-8 As shown, this embodiment provides a tumor resection device, including a resection mechanism 10, a body 20, a handle 30, a drive mechanism, a transmission mechanism, and an adsorption mechanism 40. The handle 30, the body 20, and the resection mechanism 10 are connected in sequence. The drive mechanism is installed inside the handle 30, and the transmission mechanism is installed inside the body 20 and connected to the drive mechanism and the resection mechanism 10. The drive mechanism drives the resection mechanism 10 to perform tumor resection via the transmission mechanism. The adsorption mechanism 40 is installed inside the handle 30 and the body 20. When the resection mechanism 10 removes the tumor, the adsorption mechanism 40 removes the removed tumor.

[0041] During tumor resection surgery, medical staff hold the handle 30, insert the resection mechanism 10 into the wound, and move it to the tumor resection position. The drive mechanism drives the resection mechanism 10 to perform the resection. Simultaneously, as the resection mechanism 10 removes the tumor, the suction mechanism 40 removes the removed tumor. This eliminates the problems of large wounds caused by the use of multiple surgical instruments such as surgical forceps and scalpels for tumor resection, which cannot meet the requirements of minimally invasive surgery and increases patient suffering. Therefore, in this embodiment, the tumor is removed simultaneously by suction mechanism 40, which not only simplifies and facilitates the operation but also effectively reduces the wound and alleviates patient suffering.

[0042] In this preferred embodiment, the tumor resection device has a long strip structure, and the maximum outer diameter of the cross-section of the tumor resection device is less than or equal to 10 mm, so as to truly meet the requirements of minimally invasive surgery.

[0043] In a further preferred embodiment, the cutting mechanism 10 includes a first rotating sleeve 102, a second rotating sleeve 103, a first elastic blade 104, a second elastic blade 105, a telescopic shaft 106, and a front fixed seat 101. The front fixed seat 101 is fixedly installed inside the front end of the machine body 20. The first rotating sleeve 102 and the second rotating sleeve 103 are located inside the machine body 20, and the first rotating sleeve 102 is rotatably installed on the front fixed seat 101. The second rotating sleeve 103 is sleeved on the first rotating sleeve 102 and rotatably installed with the first rotating sleeve 102.

[0044] The first elastic blade 104 and the second elastic blade 105 are located outside the front end of the body 20, and there are multiple first elastic blades 104 and multiple second elastic blades 105. Multiple first elastic blades 104 are evenly distributed around the end face circumference of the first rotating sleeve 102, and one end of multiple first elastic blades 104 is fixedly connected to the first rotating sleeve 102. Multiple second elastic blades 105 are evenly distributed around the end face circumference of the second rotating sleeve 103, and one end of multiple second elastic blades 105 is fixedly connected to the second rotating sleeve 103. Multiple first elastic blades 104 and multiple second elastic blades 105 are staggered, and multiple second elastic blades 105 are wrapped around multiple first elastic blades 104.

[0045] The telescopic shaft 106 is movably installed on the front fixed seat 101. The telescopic shaft 106 can move on the front fixed seat 101. One end of the telescopic shaft 106 extends out of the body 20 and is fixedly connected to the other end of the multiple first elastic blades 104 and multiple second elastic blades 105. When the telescopic shaft 106 extends or retracts, the conical structure formed by the multiple first elastic blades 104 and multiple second elastic blades 106 becomes larger or smaller.

[0046] The transmission mechanism is connected to the first rotating sleeve 102, the telescopic shaft 106, and the second rotating sleeve 103. The driving mechanism drives the first rotating sleeve 102 and the second rotating sleeve 103 to rotate via the transmission mechanism, and the rotation directions of the first rotating sleeve 102 and the second rotating sleeve 103 are opposite. The driving mechanism drives the telescopic shaft 106 to perform telescopic movement via the transmission mechanism.

[0047] In the initial state of this embodiment, the drive mechanism drives the telescopic shaft 106 to move relative to the body 20 via the transmission mechanism, so that one end of the telescopic shaft 106 extends out of the body 20. The extension of the telescopic shaft 106 out of the body 20 makes the conical structure formed by the multiple first elastic blades 104 and the multiple second elastic blades 105 smaller, that is, the cutting mechanism 10 retracts, and the multiple first elastic blades 104 and the multiple second elastic blades 105 are close to the telescopic shaft 106. At this time, the outer contour dimension of the cross-section of the cutting mechanism 10 is at its minimum value, so the cutting mechanism 10 can be easily inserted along the wound, effectively reducing the wound size.

[0048] When the resection mechanism 10 is inserted through the wound to reach the tumor resection position, the resection mechanism 10 operates. Specifically, the drive mechanism drives the first rotating sleeve 102 and the second rotating sleeve 103 to rotate simultaneously via the transmission mechanism, and the rotation directions of the first rotating sleeve 102 and the second rotating sleeve 103 are opposite. The first rotating sleeve 102 drives multiple first elastic blades 104 to rotate, and the second rotating sleeve 103 drives multiple second elastic blades 105 to rotate, so that the multiple first elastic blades 104 and the multiple first elastic blades 105 rotate simultaneously and in opposite directions to remove the tumor. During tumor resection, the suction mechanism 40 operates to promptly remove the removed tumor, so that tumor resection and tumor suction are performed simultaneously. The operation is simple, convenient, and quick, effectively reducing wounds and alleviating patient pain.

[0049] During tumor resection, the drive mechanism drives the telescopic shaft 106 to move relative to the machine body 20 via the transmission mechanism. One end of the telescopic shaft 106 retracts towards the machine body 20, causing the conical structure formed by the multiple first elastic blades 104 and multiple second elastic blades 105 to enlarge, thus opening the resection mechanism 10. The size of the conical structure formed by the multiple first elastic blades 104 and multiple second elastic blades 105 can be adjusted according to the degree of extension and retraction of the telescopic shaft 106 to adapt to different tumor resection needs, offering a wide range of applications and flexible and convenient use. Simultaneously, the multiple first elastic blades 104 and multiple second elastic blades 105 rotate in opposite directions, which can counteract the force on the handle 30, making it easier for medical personnel to operate.

[0050] In a further preferred embodiment, the driving mechanism includes a first motor 501, a second motor 502, and a tailstock 503, and the transmission mechanism includes a first rotating tie rod 601, a second rotating tie rod 602, a first transmission gear 603, a second transmission gear 607, an output gear 608, an internal gear ring 604, a first external gear ring 605, a second external gear ring 606, and a reversing gear 609.

[0051] The tailstock 503 is installed inside the handle 30. The first motor 501 and the second motor 502 are fixedly installed on the tailstock 503. The tailstock 503 is provided with a first through hole and a second through hole. One end of the first rotating pull rod 601 passes through the first through hole and is connected to the output shaft of the first motor 501. One end of the second rotating pull rod 602 passes through the second through hole and is connected to the output shaft of the second motor 502. The arrangement of the first through hole and the second through hole does not interfere with the rotation of the first rotating pull rod 601 and the second rotating pull rod 602.

[0052] The other end of the first rotating tie rod 601 is connected to the first transmission gear 603. The first rotating sleeve 102 is provided with the internal gear ring 604 and the first external gear ring 605. The second rotating sleeve 103 is provided with the second external gear ring 606. The first transmission gear 603 meshes with the internal gear ring 604. The reversing gear 609 is rotatably mounted on the inner wall of the front end of the body 20. The first external gear ring 605 and the second external gear ring 606 both mesh with the reversing gear 609.

[0053] The other end of the second rotating tie rod 602 is connected to the second transmission gear 607. The output gear 608 is rotatably mounted on the front fixed seat 101. The other end of the telescopic shaft 106 extends into the interior of the body 20, and the other end of the telescopic shaft 106 is provided with an external thread section 1061. The center of the output gear 608 is provided with a first internal thread hole. The output gear 608 is threadedly connected to the external thread section 1061 through the first internal thread hole. The output gear 608 meshes with the second transmission gear 607.

[0054] When the cutting mechanism 10 is working, the first motor 501 starts and drives the first rotating tie rod 601 to rotate. The rotation of the first rotating tie rod 601 drives the first transmission gear 603 to rotate. The rotation of the first transmission gear 603 drives the internal gear ring 604 to rotate, thereby driving the first rotating sleeve 102 to rotate. When the first rotating sleeve 102 rotates, it drives the reversing gear 609 to rotate under the action of the first external gear ring 605. The rotation of the reversing gear 609 drives the second rotating sleeve 103 to rotate under the action of the second external gear ring 606, thereby driving multiple first elastic blades 104 and multiple second elastic blades 105 to rotate simultaneously and in opposite directions.

[0055] When the telescopic shaft 106 extends and retracts to adjust the size of the conical structure formed by the multiple first elastic blades 104 and the multiple second elastic blades 105, specifically, the second motor 502 starts and drives the second rotating tie rod 602 to rotate. The rotation of the second rotating tie rod 602 drives the second transmission gear 607 to rotate. The rotation of the second transmission gear 607 drives the output gear 608 to rotate. Under the action of the first internal thread hole and the external thread section 1061, the rotation of the output gear 608 drives the telescopic shaft 106 to move relative to the output gear 608, thereby driving the telescopic shaft 106 to move on the front fixed seat 101.

[0056] In this embodiment, the structure of the transmission mechanism can of course be combined with other existing structural forms as long as they can meet the functional requirements of this embodiment.

[0057] See Figure 7 As shown, preferably, the first motor 501 and the second motor 502 are both fixedly mounted on the tailstock 503 by a plurality of support columns 5010.

[0058] In this embodiment, the second rotating sleeve 103 is rotatably mounted on the first rotating sleeve 102 through a raised groove structure. For example, the first rotating sleeve 102 is provided with an annular groove, and the second rotating sleeve 103 is provided with an annular protrusion that cooperates with the annular groove. The annular protrusion and the annular groove cooperate to realize the rotatable mounting of the first rotating sleeve 102 and the second rotating sleeve 103. Similarly, the second rotating sleeve 103 is rotatably mounted on the inner wall of the machine body 20.

[0059] In a further preferred embodiment, the transmission mechanism further includes a first tie rod housing 610 and a second tie rod housing 611, and the adsorption mechanism 40 includes a third tie rod housing 402, a guide pipe 401, and a water pump 403. The first tie rod housing 610 and the second tie rod housing 611 are respectively fitted onto the first rotating tie rod 601 and the second rotating tie rod 602; one end of the first tie rod housing 610 is inserted into the first through hole and fixedly connected to the tailstock 503, and the other end is fixedly connected to the front fixing seat 101; one end of the second tie rod housing 611 is inserted into the second through hole and fixedly connected to the tailstock 503, and the other end is fixedly connected to the front fixing seat 101. The water pump 403 is a miniature water pump configured according to the overall size of the tumor resection device in this embodiment.

[0060] The tailstock 503 has a third through hole. One end of the third tie rod housing 402 passes through the third through hole and is fixedly connected to the tailstock 503. The other end is fixedly connected to the front fixing seat 101. The front fixing seat 101 has an adsorption hole 1010 that communicates with the third tie rod housing 402, and the adsorption hole 1010 is connected to the cutting mechanism 10. One end of the guide tube 401 is connected to the third tie rod housing 402, and the other end of the guide tube 401 extends out of the handle 30. The water pump 403 is located inside the handle 30 and is mounted on the guide tube 401.

[0061] In this embodiment, the adsorption mechanism 40 also includes a box, etc. After the adsorption mechanism 40 sucks out the tumor, it is transferred to the box for storage. This is a conventional configuration and will not be described in detail.

[0062] When the resection mechanism 10 removes a tumor, the water pump 403 starts, and the removed tumor is sequentially sucked out into the box through the suction hole 1010, the third tie-rib outer shell 402, and the guide tube 401. Of course, the suction mechanism 40 will also remove other tissues that need to be removed during the operation, not just tumors.

[0063] In this embodiment, the adsorption mechanism 40 has only one other structural form. Of course, the existing mature medical negative pressure adsorption principle can also be used.

[0064] In this embodiment, the first tie rod outer shell 610 and the second tie rod outer shell 611 are effectively fitted over the first rotating tie rod 601 and the second rotating tie rod 602, respectively. This not only effectively protects the first rotating tie rod 601 and the second rotating tie rod 602, but also improves the transmission stability of the first rotating tie rod 601 and the second rotating tie rod 602.

[0065] To improve the flexibility of the overall tumor resection device, the body 20 of this embodiment can be adjusted at multiple angles. This allows it to avoid key blood vessels and nerves when the resection mechanism 10 is inserted along the wound to the tumor resection position, and also facilitates multi-directional resection and aspiration of the tumor. Specifically, the drive mechanism includes a linear motion drive 505 and a rear fixing seat 504; the body 20 includes a torso 201, a bending joint 202, and a guide block 203. Multiple torsos 201, bending joints 202, and guide blocks 203 are present, and these torsos 201 and bending joints 202 are sequentially and alternately connected. The front and rear ends of the body 20 are both composed of the torso 201, and the torso 201 at the rear end of the body 20 is connected to the handle 30. The tailstock 503 is divided into three independent parts, with the first through hole, the second through hole, and the third through hole located on the three parts of the tailstock 503 respectively. The tailstock 503 is movably mounted to the handle 30, and the tailstock 503 is movable relative to the handle 30. There are three linear motion drive members 505, which are fixedly mounted on the inner wall of the handle 30, and the three linear motion drive members 505 are respectively connected to the three parts of the tailstock 503.

[0066] The guide block 203 is provided in the middle of the torso 201. The guide block 203 is provided with three first guide holes. The first tie rod shell 610, the second tie rod shell 611 and the third tie rod shell 402 pass through the three first guide holes respectively.

[0067] See Figure 1 and 2As shown, there are three bending joints 202, four torsos 201, and three guide blocks 203. The number of bending joints 202, torsos 201, and guide blocks 203 is determined according to actual needs. Taking the first tensioning shell 610 as an example, the corresponding linear motion drive 505 is activated to drive the block corresponding to the tailstock 503 to move. The block corresponding to the tailstock 503 moves and pulls the first tensioning shell 610, which is stretched. The second tensioning shell 611 and the third tensioning shell 402 are at their normal lengths, causing the body 20 to bend in the direction of the first tensioning shell 610, and the corresponding bending joint 202 bends. Similarly, the second tensioning shell 610 and the second tensioning shell 611 can also be pulled, or the first tensioning shell 610 and the second tensioning shell 611 can be pulled simultaneously, so as to achieve adjustment of the body 20 at any angle, which improves the range of motion of the tumor resection device in this embodiment and is more conducive to tumor resection. The bending degree of the machine body 20 is adjusted by moving the corresponding block of the tailstock 503 according to the linear motion drive 505. In this embodiment, the first rotating tie rod 601, the second rotating tie rod 602, the first tie rod shell 610, the second tie rod shell 611, and the third tie rod shell 402 can all be elastically bent. Therefore, when the angle of the machine body 20 is adjusted, the power transmission of the first rotating tie rod 601 and the second rotating tie rod 602 will not be affected.

[0068] Guide blocks 203 are installed in the middle of the body 201, which can not only improve the overall structural strength of the fuselage 20, but also guide the fuselage 20 when it bends.

[0069] In a preferred embodiment, the linear motion drive 505 includes a screw 5051 and a third motor 5050. Each of the three sections of the tailstock 503 has a second internal threaded hole 5030. Corresponding to each section of the tailstock 503: one end of the screw 5051 is rotatably connected to the rear fixed seat 504; the screw 5051 passes through the second internal threaded hole 5030 and is threadedly connected to it; the other end of the screw 5051 is connected to the output end of the third motor 5050. The third motor 5050 is fixedly mounted on the inner wall of the handle 30. When the third motor 5050 is activated, it drives the screw 5051 to rotate. The rotation of the screw 5051, under the action of the second internal threaded hole 5030, causes the corresponding section of the tailstock 503 to move on the screw 5051. Of course, the linear motion drive 505 can also be an existing electric push rod, etc.

[0070] In a preferred embodiment, the driving mechanism further includes a rear fixed seat 504 and guide posts 506. The rear fixed seat 504 is fixedly installed inside the handle 30. There are multiple guide posts 506, and the tailstock 503 has multiple second guide holes of the same number and opposite positions as the guide posts 506. Each piece of the tailstock 503 has a set of second guide holes, and the multiple guide posts 506 are inserted into the multiple second guide holes. Under the action of the second guide holes and guide posts 506, the tailstock 503 is guided, ensuring the movement accuracy of the tailstock 503.

[0071] See Figure 9 As shown, in a further preferred embodiment, the bending joint 202 includes a flexible outer shell 2020, an electromagnetically induced liquid filled within the flexible outer shell 2020, two electrodes 2021 connected to the flexible outer shell 2020, and a controller 2022 connected to the two electrodes 2021. The controller 2022 adjusts the current to control the solidification of the electromagnetically induced liquid, causing the bending joint 202 to soften or harden. Ultimately, each bending joint 202 can soften or harden, allowing multiple bending joints 202 to be individually controlled to adjust their angles, providing high flexibility. Furthermore, the hardening of the bending joint 202 achieves locking after angle adjustment, thus improving the stability of the body 20 after angle adjustment. The controller 2022 can be an existing mature PLC programmable controller, but this is not the focus of this embodiment and will not be elaborated upon further.
