Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a tumor stripper for tumor surgery. Background Art

[0002] Gynecological tumor surgery refers to the surgical treatment of tumors occurring in the female reproductive system (such as the uterus, ovaries, fallopian tubes, vagina, etc.). With the progress of medical technology, minimally invasive surgery has gradually become the mainstream choice for gynecological tumor treatment.

[0003] Among them, under the leadership of the Da Vinci surgical robot, laparoscopic surgery combined with a high-definition camera and delicate surgical instruments can precisely excise tumor tissues. During the surgery, a pneumoperitoneum needle puncture point is made, and carbon dioxide gas is injected to establish a pneumoperitoneum to provide sufficient operating space for the surgery. Other puncture holes are respectively positioned, and the robotic arms of the Da Vinci surgical robot are connected. Surgical clamps, cutting knives, cameras and other instruments connected to the robotic arms are inserted into the patient's body through the puncture holes. The doctor controls the robotic arms through the console and, with the assistance of a high-definition three-dimensional imaging system, precisely excises uterine fibroids, and then selects a suitable removal method according to the size and location of the tumor. For smaller tumors, they can be directly removed through the puncture holes or an enlarged umbilical incision. For larger tumors, tumor volume reduction may be required first, the tumor is shredded or cut into small pieces, and then removed one by one.

[0004] During the above surgical process, especially when reducing the volume of a larger tumor mass, instruments such as surgical clamps need to move in and out of the body multiple times, seriously affecting the surgical efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a tumor stripper for tumor surgery to improve the technical problem of low surgical efficiency in the prior art.

[0006] The present invention is achieved through the following technical solutions:

[0007] A tumor stripper for tumor surgery includes an installation tube, a clamping tube, an air tube installed on the clamping tube, and a camera installed at the working end of the clamping tube. A surgical knife is installed on the installation tube. It further includes an operating shaft, the working end of the operating shaft is slidably and rotatably connected inside the clamping tube, a surgical clamp is installed at the working end of the operating shaft, the operating shaft is used to drive the surgical clamp to open and close to clamp the tumor, and a storage chamber is also communicated with the outer wall of the operating end of the clamping tube, and the storage chamber is used to receive and store the tumor mass clamped by the surgical clamp.

[0008] Further, an installation ring is coaxially and rotatably connected to the working end of the operating shaft. The installation ring is axially slidably connected to the inner wall of the pipe clamp. The working end of the operating shaft is also drivingly connected to a transmission assembly. The transmission assembly is connected to the side of the installation ring facing away from the operating shaft. The operating end of the surgical clip is connected to the transmission assembly.

[0009] Further, the transmission assembly includes a gear coaxially and fixedly connected to the working end of the operating shaft and two parallel racks. Both of the two racks are engaged with the gear and are slidably connected to the side of the installation ring facing away from the operating shaft. The surgical clip includes a rotating shaft and two clamping bodies rotatably connected to the rotating shaft in the middle. The operating ends of the two clamping bodies are respectively rotatably connected to the two racks.

[0010] Further, two opposite vertical slots are axially formed in the inner wall of the pipe clamp. The installation ring is formed with first sliders adapted to and slidably connected to the two vertical slots at the same time.

[0011] Further, a receiving port is formed in the side wall of the pipe clamp; the storage bin includes a bin body fixedly connected to the pipe clamp, a receiving bin slidably connected in the bin body, and a spring. The bin body is laterally open and communicates with the receiving port. The receiving bin is slidably connected to the bin body along the opening direction of the bin body. The sliding path of the receiving bin is located in the opening direction of the receiving port. And the receiving bin is laterally open and upward open along the opening direction of the bin body. The spring extends along the opening direction of the bin body, and the two ends are respectively fixedly connected to the bin body and the receiving bin.

[0012] Further, the receiving bin includes a receiving box slidably connected to the bin body, a lower plate fixedly connected to one end of the receiving box close to the spring, and an upper plate connected to the upper end of the lower plate. The receiving box has an upper opening structure, and the other end extends into the receiving port and abuts against the operating shaft. The spring is fixedly connected to the upper plate.

[0013] Further, a ring groove is formed in the side wall of the operating shaft. The ring groove has a flared structure and forms an upper guiding surface extending obliquely upward toward the inner wall of the pipe clamp; a pushing port is further formed in the side wall of the pipe clamp above the receiving port; the receiving bin further includes a guiding block. One end of the guiding block close to the spring is fixedly connected to the upper end of the upper plate, and the guiding block is provided with an upper inclined surface cooperating with the upper guiding surface. The diameter of the pipe clamp is D. The transverse length of the receiving box is greater than the transverse length of the guiding block, and the length difference is L. The depth of the ring groove is M, M > L, M + L > 2 / 3D.

[0014] Further, a guiding plate is fixedly connected to the lower side of the mounting ring facing away from the operating shaft. The end of the guiding plate away from the mounting ring extends obliquely towards the axial direction of the pipe clamp. The transverse length of the guiding plate in the radial direction of the pipe clamp is X, and X > L.

[0015] Further, the annular groove further forms a lower guiding surface located on the lower side of the upper guiding surface. The inclination direction of the lower guiding surface is the same as that of the upper guiding surface.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0031] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side" and "the other side" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0033] In addition, terms such as "the same" do not mean that the components are required to be absolutely the same, but there can be slight differences. The term "vertical" only means that the positional relationship between components is more vertical relative to "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0034] This embodiment aims to facilitate the solution of the problem that when using a Da Vinci surgical robot to remove uterine fibroids in the prior art, a surgical clip 6 is used to take out the tumor through a puncture hole. When the tumor is large, the tumor needs to be cut into small pieces. However, taking out the small tumor pieces multiple times increases the number of times the surgical clip 6 travels back and forth inside and outside the body, making it inconvenient to take out a large tumor, thus easily affecting the resection efficiency. At the same time, it can also reduce the space required for the surgical clip 6 to operate inside the body.

[0035] Please refer to Figure 1-8 , the present invention provides a technical solution: a tumor stripper for tumor surgery, including an installation tube 1, a clamping tube 2, an air tube 3 installed on the clamping tube 2, and a camera 4 installed at the working end of the clamping tube 2. A surgical knife 11 is installed on the installation tube 1. It also includes an operating shaft 5. The working end of the operating shaft 5 is slidably and rotatably connected inside the clamping tube 2. A surgical clip 6 is installed at the working end of the operating shaft 5. The operating shaft 5 is used to drive the surgical clip 6 to open and close to clamp the tumor. A storage bin 7 is also communicated with the outer wall of the operating end of the clamping tube 2. The storage bin 7 is used to receive and store the tumor pieces clamped by the surgical clip 6.

[0036] The doctor manipulates the installation tube 1 and the clamping tube 2 to enter the patient's body. The air outlet end of the trachea 3 and the camera 4 enter the patient's body at the same time. The air inlet end of the trachea 3 is connected to carbon dioxide gas to fill the patient's abdomen with carbon dioxide gas, making the patient's abdominal cavity distend, providing sufficient operating space for the operation, and the camera 4 is used to take real-time pictures of the patient's internal conditions. During the operation, with the cooperation of the camera 4, by operating the operating shaft 5, the clamping end of the surgical clamp 6 extends out of the working end of the clamping tube 2, and the tumor in the patient's body is clamped through the clamping tube 2. Subsequently, a small piece of the tumor is cut off by the scalpel 11. After cutting, under the operation of the operating shaft 5, the surgical clamp 6 clamping the tumor mass retracts into the clamping tube 2 to the position where the storage bin 7 is located. The storage bin 7 receives and stores the tumor mass clamped by the surgical clamp 6. Then, under the operation of the operating shaft 5, the next cutting operation is performed through the scalpel 11 and the surgical clamp 6. This cycle continues until multiple cutting operations on the tumor are completed. Through this cutting method, the surgical clamp 6 always moves back and forth within the clamping tube 2 to complete the transfer of the tumor mass, eliminating the need to repeatedly move the surgical clamp 6 separately and complete multiple transfer operations, and eliminating the need to move the surgical clamp 6 to other positions within the patient's body, improving the efficiency of tumor extraction. Moreover, the clamping tube 2 protects the movement of the surgical clamp 6 and can prevent the surgical clamp 6 from causing harm to the patient during movement. At the same time, the clamping tube 2 forms the installation basis for the trachea 3, the camera 4, and the surgical clamp 6. Compared with the prior art where the trachea 3, the camera 4, and the surgical clamp 6 are all separate and independent instruments that need to cooperate with each other during operation, the occupied space is relatively smaller, which is more conducive to performing treatment operations within the patient's body.

[0037] Among them, the installation tube 1 and the clamping tube 2 are both connected to the robotic arm of the da Vinci surgical robot. The operating ends of the scalpel 11 and the operating shaft 5 are both movably connected to the robotic arm of the da Vinci surgical robot, and the installation tube 1 and the clamping tube 2 can both rotate arbitrarily, enabling the doctor to manipulate the scalpel 11 and the operating shaft 5 through the control system of the da Vinci surgical robot. The scalpel 11 cuts the tumor, and under the operation of the operating shaft 5, the tumor is clamped by the surgical clamp 6, thereby removing the tumor. The da Vinci surgical robot is one of the most advanced technologies for minimally invasive surgery and is a mature prior art, which will not be elaborated here.

[0038] The air inlet end of the trachea 3 is connected to carbon dioxide gas. It is installed through a through hole preset on the side wall of the clamping tube 2, and its air outlet end extends out of the working end of the clamping tube 2 and is provided with an opening. The camera 4 is installed at the working end of the clamping tube 2.

[0039] Among them, the operating end refers to the end held by the robotic arm of the da Vinci surgical robot. The working end refers to the other end that operates on the tumor.

[0040] Please refer to Figure 2-8In this embodiment: the operating end of the operating shaft 5 is coaxially connected to the mounting ring 8, the mounting ring 8 is axially slidably connected to the inner wall of the clamp tube 2, the operating end of the operating shaft 5 is also transmission-connected to a transmission assembly 9, the transmission assembly 9 is connected to the side of the mounting ring 8 away from the operating shaft 5, and the operating end of the surgical clamp 6 is connected to the transmission assembly 9.

[0041] When performing a tumor cutting operation, the action on the operating end of the operating shaft 5 is transmitted to the transmission component 9, and the operation of the surgical clamp 6 is realized through the transmission component 9, so that the surgical clamp 6 completes the opening and closing action. After the surgical clamp 6 clamps the tumor mass, the operating shaft 5 is pulled, so that the operating shaft 5 slides relative to the clamp tube 2, and the mounting ring 8 slides relative to the clamp tube 2 at the same time.

[0042] An opening structure is formed on the inner side of the mounting ring 8 to allow the transmission assembly 9 to pass through and achieve connection with the active end of the operating shaft 5 .

[0043] On the basis of the above embodiment, a hanging groove 52 is coaxially provided at the working end of the operating shaft 5, and the hanging groove 52 is an annular groove structure, and a ring block 83 adapted to and rotatably connected to the hanging groove 52 is formed at one end of the mounting ring 8, so that the operating shaft 5 and the mounting ring 8 are installed by the ring block 83 being clamped in the hanging groove 52. The cross section of the hanging groove 52 is stepped or dovetailed, so that the ring block 83 will not fall out of the hanging groove 52, and the relative rotation installation between the operating shaft 5 and the mounting ring 8 is guaranteed.

[0044] See also Figure 2-4 In this embodiment: the transmission assembly 9 includes a gear 91 coaxially fixedly connected to the working end of the operating shaft 5 and two racks 92 parallel to each other, the two racks 92 are both meshed with the gear 91, and are both slidably connected to the side of the mounting ring 8 away from the operating shaft 5, the surgical clamp 6 includes a rotating shaft 61 and two clamping bodies 62 whose middle parts are both rotatably connected to the rotating shaft 61, and the operating ends of the two clamping bodies 62 are respectively rotatably connected to the two racks 92.

[0045] When performing a tumor cutting operation, by applying a force to the operating shaft 5, the clamping ends of the two clamping bodies 62 of the surgical clip 6 are simultaneously pushed out of the clip tube 2. After determining the clamping position, the operating shaft 5 is rotated, causing the gear 91 to rotate. The two racks 92 meshing with the gear 91 move in opposite directions, and the clamping ends of the two clamping bodies 62 open. When reaching the tumor position, the operating shaft 5 is rotated in the reverse direction until the clamping ends of the two clamping bodies 62 close and clamp the tumor. Then, a small piece of the tumor is cut off by the scalpel 11. After cutting, the operating shaft 5 is retracted, causing the surgical clip 6 clamping the tumor mass to retract into the clip tube 2 until reaching the position of the storage bin 7. Then, the operating shaft 5 is rotated in the reverse direction until the clamping ends of the two clamping bodies 62 open, and the tumor falls and is received and stored by the storage bin 7. After that, under the operation of the operating shaft 5, the next cutting operation is performed by the scalpel 11 and the surgical clip 6. This cycle continues until multiple cutting operations on the tumor are completed.

[0046] Wherein, a connecting rod is coaxially and fixedly connected to the gear 91 to extend into the mounting ring 8 and be coaxially and fixedly connected to the operating shaft 5.

[0047] On the basis of the above embodiment, two parallel transverse slots 84 are formed on the side of the mounting ring 8 facing away from the operating shaft 5. The transverse slots 84 are stepped slots or dovetail slots, and two transverse blocks 921 adapted to and slidably connected to the transverse slots 84 are fixedly connected to the two racks 92. The two transverse blocks 921 are respectively adapted to and slidably connected to the two transverse slots 84 to realize the installation of the two racks 92.

[0048] Rotary joints 621 are rotatably connected to the operating ends of the two clamping bodies 62. The two rotary joints 621 are both in a U-shaped structure, and the closed ends are in a round shaft shape and are rotatably connected to the corresponding clamping bodies 62, and the open ends are fixedly connected to the corresponding racks 92. When the gear 91 rotates and the two racks 92 move towards or away from each other, the two clamping bodies 62 both change their angles through the rotary joints 621 and the corresponding racks 92, and the two clamping bodies 62 open or close.

[0049] The operating ends of the two clamping bodies 62 are far away from each other to form a space corresponding to the gear 91. The working ends of the two clamping bodies 62 are close to each other to ensure stable clamping of the target object. Clamping blocks 622 are fixedly connected to the working ends of the two clamping bodies 62. The two clamping blocks 622 are arranged oppositely, and convex ribs are fixedly connected to the opposite sides of the two clamping blocks 622 to realize stable clamping of the target object.

[0050] Please refer to Figure 2-4 , in this embodiment: Two opposite vertical slots 21 are axially formed on the inner wall of the clip tube 2, and a first slider 81 adapted to and slidably connected to the two vertical slots 21 at the same time is formed on the mounting ring 8.

[0051] The mounting ring 8 is limited by the vertical slot 21 so that the mounting ring 8 can only slide along the axial direction of the clamping tube 2, ensuring that when the rotating operating shaft 5 drives the gear 91 to rotate, the two racks 92 can slide smoothly relative to the mounting ring 8.

[0052] The vertical clamping groove 21 is a stepped groove or a dovetail groove to prevent the mounting ring 8 from being separated and to ensure that the mounting ring 8 and the clamping tube 2 do not rotate relative to each other.

[0053] On the basis of the above embodiment, both ends of the rotating shaft 61 are fixedly connected with second sliders 611, and the second sliders 611 are adapted and slidably connected to the corresponding vertical slots 21. When the two clamping bodies 62 are closed or opened, the rotating shaft 61 moves relative to the clamp tube 2 through the second sliders 611. The second sliders 611 are limited by the vertical slots 21, so that the surgical clamp 6 is always located in the middle of the clamp tube 2, and each opening action can be opened to the maximum, and the maximum opening angle is not greater than the diameter D of the clamp tube 2.

[0054] The vertical slot 21 does not penetrate the working end of the clamp tube 2 to prevent the second slider 611 from slipping out of the vertical slot 21 and the surgical clip 6 from detaching from the clamp tube 2 during operation.

[0055] See also Figure 2-8 In this embodiment: a receiving port 22 is provided on the side wall of the clamp tube 2; the storage bin 7 includes a bin body 71 fixedly connected to the clamp tube 2, a receiving bin 72 slidably connected to the bin body 71, and a spring 73; the bin body 71 is open laterally and communicates with the receiving port 22; the receiving bin 72 is slidably connected to the bin body 71 along the opening direction of the bin body 71; the sliding path of the receiving bin 72 is located in the opening direction of the receiving port 22; the receiving bin 72 is open laterally and upwardly along the opening direction of the bin body 71; the spring 73 extends along the opening direction of the bin body 71, and its two ends are fixedly connected to the bin body 71 and the receiving bin 72, respectively.

[0056] When the operating shaft 5 closes the receiving port 22, the spring 73 is in a compressed state, so that the receiving bin 72 is subjected to force and always abuts against the side wall of the operating shaft 5 through the receiving port 22; when the surgical clamp 6 holding the tumor mass retracts into the clamp tube 2 and reaches the position of the storage bin 7, the operating shaft 5 continues to pull out the clamp tube 2, and when the operating shaft 5 no longer forms a limit on the receiving bin 72, the receiving bin 72 extends into the receiving port 22 and enters the clamp tube 2 under the action of the spring 73, and when the surgical clamp 6 is located at the upper opening of the receiving bin 72, the operating shaft 5 is rotated in the opposite direction until the clamping ends of the two clamping bodies 62 are opened, the tumor falls, and the falling tumor mass is received and stored by the receiving bin 72.

[0057] The storage body 71 includes a storage cylinder 711 and a cover plate 712. The storage cylinder 711 has a through-opening structure, and one end is fixedly connected to the outer wall of the clamping tube 2 and communicates with the receiving port 22. The cover plate 712 is detachably connected to the other end of the storage cylinder 711 by screws to form a closure for the storage cylinder 711. The receiving bin 72 is slidably connected to the storage cylinder 711, and one end of the spring 73 is fixedly connected to the inner side of the cover plate 712. After the operation is completed, the receiving bin 72 is taken out by removing the cover plate 712 and under the connection of the spring 73 to complete the cleaning work of the removed tumor mass.

[0058] Please refer to Figure 2-8 , in this embodiment: The receiving bin 72 includes a receiving box 721 slidably connected to the storage body 71, a lower plate 722 fixedly connected to the lower end of the receiving box 721 near one end of the spring 73, and an upper plate 723 with the lower end connected to the upper end of the lower plate 722. The receiving box 721 has an upper-opening structure, and the other end extends into the receiving port 22 and abuts against the operating shaft 5. The spring 73 is fixedly connected to the upper plate 723.

[0059] When the surgical clip 6 clamping the tumor mass retracts into the clamping tube 2 and reaches the position of the storage bin 7, the operating shaft 5 continues to be withdrawn from the clamping tube 2. When the operating shaft 5 no longer forms a limit for the receiving bin 72, the receiving box 721 extends into the receiving port 22 and enters the clamping tube 2 under the action of the spring 73. When the surgical clip 6 is located at the upper opening of the receiving box 721, the operating shaft 5 is rotated in the reverse direction until the clamping ends of the two clamping bodies 62 open, and the tumor falls and is received and stored by the receiving box 721 for the falling tumor mass.

[0060] In this embodiment, the receiving box 721 is slidably connected to the storage cylinder 711. A lower groove 7111 is formed on the inner wall of the storage cylinder 711, and the receiving box 721 is formed with a first extension plate that is adapted to and slidably connected to the lower groove 7111 to guide the sliding of the receiving box 721.

[0061] Please refer to Figure 2-8 , in this embodiment: A ring groove 51 is formed on the side wall of the operating shaft 5. The ring groove 51 has a flared structure and is formed with an upper guiding surface 511 that extends upward and obliquely toward the inner wall of the clamping tube 2. A pushing port 23 is further formed on the side wall of the clamping tube 2 above the receiving port 22. The receiving bin 72 further includes a guiding block 724. One end of the guiding block 724 near the spring 73 is fixedly connected to the upper end of the upper plate 723, and the guiding block 724 is provided with an upper inclined surface 7241 that cooperates with the upper guiding surface 511. The diameter of the clamping tube 2 is D, the transverse length of the receiving box 721 is greater than the transverse length of the guiding block 724, and the length difference is L. The depth of the ring groove 51 is M, M > L, and M + L > 2 / 3D.

[0062] When the operating shaft 5 continuously withdraws the clamping tube 2, and the receiving box 721 extends into the receiving port 22 under the action of the spring 73 and enters the clamping tube 2, the guiding block 724 extends into the annular groove 51, and the upper inclined surface 7241 abuts against the upper guiding surface 511. Since M + L > 2 / 3D, the surgical clip 6 is located at the upper opening of the receiving box 721. Rotate the operating shaft 5 in the reverse direction, and the guiding block 724 rotates at the annular groove 51 until the clamping ends of the two clamping bodies 62 open. The tumor falls and the receiving box 721 receives and stores the falling tumor mass. Then, rotate the operating shaft 5 in the reverse direction until the clamping ends of the two clamping bodies 62 close at the upper opening of the receiving box 721. Apply a force to the operating shaft 5 to make the operating shaft 5 move towards the working end of the clamping tube 2. The upper inclined surface 7241 applies a force to the upper guiding surface 511, causing the guiding block 724 and the receiving box 721 to be simultaneously retracted into the housing 71. When the guiding block 724 abuts against the side wall of the operating shaft 5, since M > L, the receiving box 721 is retracted along the path where its end moves away from the closed clamping ends of the two clamping bodies 62. The two clamping bodies 62 with the closed clamping ends continue to move under the action of the moving operating shaft 5 until the receiving box 721 is completely retracted into the housing 71 for the next cutting operation.

[0063] In this embodiment, the guiding block 724 is slidably connected in the barrel 711. An upper groove 7112 is formed on the inner wall of the barrel 711, and the guiding block 724 is formed with a second extension plate that is adapted to and slidably connected to the upper groove 7112 to guide the sliding of the guiding block 724.

[0064] Please refer to Figure 2-8 , in this embodiment: A guiding plate 82 is fixedly connected to the lower side of the mounting ring 8 facing away from the operating shaft 5. The end of the guiding plate 82 away from the mounting ring 8 extends obliquely towards the axis direction of the clamping tube 2. The transverse length of the guiding plate 82 in the radial direction of the clamping tube 2 is X, and X > L.

[0065] When the guiding block 724 and the receiving box 721 are simultaneously retracted into the housing 71 and the guiding block 724 abuts against the side wall of the operating shaft 5, since X > L, the end of the receiving box 721 is located directly below the guiding plate 82. At this time, the two clamping bodies 62 with the closed clamping ends continue to move under the action of the moving operating shaft 5, and the guiding plate 82 guides the receiving box 721 until the receiving box 721 is completely retracted into the housing 71 for the next cutting operation.

[0066] Moreover, the mounting ring 8 abuts against the operating shaft 5 so that no gap is formed between their outsides, ensuring the smooth sliding of the receiving box 721 of the storage bin 7.

[0067] Moreover, the box wall of the receiving box 721 away from the lower plate 722 is of an inclined plate structure and slopes upward towards the upper plate 723. When the closed surgical clip 6 moves downward relative to the receiving box 721 and enters the patient's body, this inclined plate structure (which has been retracted by a distance M under the guidance of the guiding block 724) can form a guiding effect on the closed surgical clip 6. At the same time, as the surgical clip 6 continues to enter, this inclined plate structure can form a cooperative effect with the guiding plate 82, enabling the receiving box 721 to be smoothly retracted.

[0068] Please refer to Figure 2-8 In this embodiment: The annular groove 51 also has a lower guiding surface 512 located below the upper guiding surface 511, and the inclination direction of the lower guiding surface 512 is the same as that of the upper guiding surface 511.

[0069] When the surgical clip 6 clamping the tumor mass retracts into the clamping tube 2 and the receiving box 721 extends into the receiving port 22 and enters the clamping tube 2 under the action of the spring 73, continuously pulling the operating shaft 5, the lower guiding surface 512 abuts against the receiving box 721 and forms a guiding effect on the receiving box 721, enabling the receiving box 721 to be retracted again, ensuring that the operating shaft 5 can be continuously pulled until the surgical clip 6 is located at the upper opening of the receiving box 721.

[0070] Moreover, the guiding block 724 is provided with a lower inclined surface 7242 that cooperates with the lower guiding surface 512. When it is necessary to separate the clamping tube 2 and the operating shaft 5 after the operation is completed, a force can be applied to the operating shaft 5. The lower inclined surface 7242 cooperates with the lower guiding surface 512, causing the guiding block 724 that enters the annular groove 51 to be squeezed back into the housing 71.

[0071] Please refer to Figure 2-8 In this embodiment: The lower end of the upper plate 723 is slidably connected to the upper end of the lower plate 722, and the receiving box 721 is inclined, with the end connected to the lower plate 722 sloping downward.

[0072] The other end of the receiving box 721 away from the lower plate 722 forms a height, which can form a guiding effect on the tumor mass falling on the receiving box 721, causing the tumor mass falling on the receiving box 721 to roll towards one end of the receiving box 721 to complete collection, ensuring that the tumor mass entering the receiving box 721 does not obstruct the subsequent falling tumor mass and completing smooth collection.

[0073] Among them, the upper plate 723 has a vertical opening, and the upper end of the lower plate 722 is adapted to and extends into the opening of the upper plate 723.

[0074] On the basis of the above embodiment, the lower groove 7111 is an inclined groove, and the lower side of the barrel 711 is inclined, and the inclination directions are the same as that of the receiving box 721.

[0075] When the surgical clip 6 holding the tumor mass is pulled and moves relative to the clip tube 2, when the receiving box 721 enters the annular groove 51 under the action of the spring 73, as the surgical clip 6 and the operating shaft 5 continue to move, the lower guiding surface 512 can exert a pushing force on the receiving box 721, causing the receiving box 721 to retract to ensure the continuous retraction of the operating shaft 5 until the surgical clip 6 reaches the upper opening of the receiving box 721, and the guiding block 724 enters the annular groove 51 at the same time. During this process, due to the inclined setting of the receiving box 721, the receiving box 721 is more easily forced to retract.

[0076] When the receiving box 721 enters and exits the housing 71, the upper plate 723 and the lower plate 722 slide relative to each other.

[0077] Working principle: During operation, with the cooperation of the camera 4, by operating the operating shaft 5, the clamping ends of the two clamping bodies 62 of the surgical clip 6 are simultaneously pushed out of the clip tube 2. After determining the clamping position, rotate the operating shaft 5 to make the gear 91 rotate, and the two racks 92 meshing with the gear 91 move in opposite directions, and the clamping ends of the two clamping bodies 62 open. When reaching the tumor position, rotate the operating shaft 5 in the reverse direction until the clamping ends of the two clamping bodies 62 close and clamp the tumor, and then cut off a small piece of the tumor with the scalpel 11. At this time, the receiving box 721 abuts against the side wall of the operating shaft 5.

[0078] After cutting, under the operation of the operating shaft 5, the surgical clip 6 holding the tumor mass retracts into the clip tube 2 until it reaches the position of the receiving bin 7. During this process, the annular groove 51 first reaches the plane where the receiving box 721 of the receiving bin 7 is located. The receiving box 721 enters the annular groove 51 under the action of the spring 73. Continuously pull the operating shaft 5, and under the pushing action of the lower guiding surface 512 on the receiving box 721, the receiving box 721 retracts into the housing 71. Continuously pull the operating shaft 5 until the guiding block 724 enters the annular groove 51 from the pushing port 23, and the receiving box 721 enters the clip tube 2 from the receiving port 22 and opens upward towards the surgical clip 6 and the clamped tumor mass. At this time, since M + L > 2 / 3D, the surgical clip 6 is located at the upper opening of the receiving box 721.

[0079] After that, rotate the operating shaft 5 in the reverse direction to release the tumor mass by the two clamping bodies 62. The tumor mass falls into the receiving box 721. Due to the inclination of the receiving box 721, the falling tumor mass rolls to the lower end of the inclined receiving box 721; then rotate the operating shaft 5 in the reverse direction to close the two clamping bodies 62.

[0080] Thereafter, an axial force is applied to the operating shaft 5, such that the upper guiding surface 511 applies a force to the upper inclined surface 7241 of the guiding block 724, causing the guiding block 724 to retract until it abuts against the side wall of the operating shaft 5. At this time, since M > L, the receiving box 721 is retracted along the path where its end moves away from the closing clamping ends of the two clamping bodies 62. The operating shaft 5 is continuously moved. Since X > L, until the end of the receiving box 721 is located directly below the guiding plate 82. The guiding plate 82 guides the receiving box 721, causing the receiving box 721 to continue to retract until the receiving box 721 abuts against the side wall of the mounting ring 8. The operating shaft 5 is continuously moved, and the receiving box 721 passes through the mounting ring 8 and abuts against the side wall of the operating shaft 5. The operating shaft 5 is continuously moved, and under the action of the spring 73, the receiving box 721 re-enters the annular groove 51. The operating shaft 5 is continuously moved, and under the action of the upper guiding surface 511, the receiving box 721 retracts until it abuts against the side wall of the operating shaft 5. At this time, the surgical clip 6 returns to its original position, and the next cutting operation can be performed.

[0081] Finally, after the tumor is completely divided, the cover plate 712 can be removed and pulled. Under the action of the spring 73, the receiving box 721 is pulled out to process the tumor mass.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
