Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a tissue separator for clinical use in the lungs. Background Art

[0002] Lung tissue separation surgery is a key step in clinical operations such as thoracic surgery, tumor resection, and lung transplantation. Its accuracy and minimally invasive nature directly affect the postoperative recovery speed and complication incidence. However, existing tissue separation instruments have problems such as high operation redundancy and high risk of tissue damage when dealing with complex scenarios such as high-density areas and vascular intersection areas of lung tissue.

[0003] Firstly, lung tissue (especially in the hilar region and para-mediastinal region) is rich in blood vessels, bronchi, and lymphatic networks. During cutting and separation, local accumulation is easily formed due to tissue elastic retraction, resulting in a 60%-70% reduction in the visible area of the surgical field. When existing instruments are used for lung tissue separation, additional retractors or suction devices are required to push away the accumulated tissue. However, frequent switching of instruments increases the single operation time by 8-12 minutes, and inaccurate control of the pulling force may tear thin-walled blood vessels or alveolar structures.

[0004] Secondly, traditional surgical methods require the step-by-step use of an electrocoagulation hook, tissue forceps, and suction device: first, a hook-shaped instrument is used to incise the pleura, and then the clamping instrument is switched to remove the target tissue. However, during the alternation of instruments, the tissue exposed at the incision is displaced due to respiratory movement, forcing the surgeon to reposition, significantly prolonging the thermal exposure time. Summary of the Invention

[0005] The purpose of the present invention is to provide a tissue separator for clinical use in the lungs, which can push away the tissue near the separation site during lung tissue separation, avoid tissue covering and obscuring the separated part, affecting the separation operation, and can also control the orientation of the push plate before pushing away the lung tissue, thereby selecting the lung tissue to be pushed away, improving the practicality, and can achieve the integration of separation and extraction, as well as the precise resection of the excised tissue, improving the portability and practicality.

[0022] The technical effects achieved by the present invention are as follows:

[0023] The pushing and separating assembly and the driving assembly of the present invention can push away the tissues near the separating part when separating the lung tissues, so as to avoid the tissues covering the separated part and affecting the separation operation; when separating the lung tissues, pull the moving part of the driving assembly to drive the pushing plate of the pushing and separating assembly to rotate outwards, push away the tissues near the separating part, and then the rebounding part of the driving assembly drives the opening part to reset, so that the guide wire tube can move deeper into the lung tissues, and then drive the pushing plate to rotate outwards again to form a continuous pushing action, realizing convenient and fast pushing away of the lung tissues and facilitating the separation operation;

[0024] The pushing and separating assembly of the present invention can control the orientation of the pushing plate before pushing away the lung tissues, so as to select the lung tissues to be pushed away and improve the practicability; when performing the lung tissue separation operation and pushing away the lung tissues near the separating part, if the position to be pushed away is on one side (upper or lower) of the separating part, the driving part of the pushing and separating assembly can be driven to drive the rotating plate to rotate, and the rotation of the rotating plate drives the pushing plate to rotate, so as to control the orientation of the pushing plate, so that the pushing plate can be opened to select the lung tissues in a certain direction for pushing away, improving the practical performance;

[0025] The negative pressure port and the scalpel of the present invention can achieve an integrated integration of separation and extraction, and utilize the adsorption of the negative pressure port for precise separation of lung tissue; when cutting lung tissue, the guide wire tube is driven to move so that the negative pressure port fits on the surface of the lung tissue to be excised. Immediately afterwards, the negative pressure port operates to adsorb the outer skin of the lung tissue. Subsequently, the scalpel is driven to fit on the outer skin of the lung tissue and move circularly along the negative pressure port to cut open the outer skin of the lung tissue. Immediately afterwards, the guide wire tube is pulled outwards, creating a gap between the outer skin of the lung tissue and part of the tissue and the interior of the lung tissue. At this time, the inclination angle of the scalpel is adjusted so that it can cover the center of the negative pressure port, and the scalpel is driven to move circularly again to completely excise the outer skin of the lung tissue and part of the tissue, achieving separation. At this time, the excised tissue remains in the negative pressure port, and it can be taken out. Description of the Drawings

However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention.

[0043] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in a preferred implementation manner" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively mutually exclusive embodiment with other embodiments.

[0044] Thirdly, the present invention is described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present invention, for the convenience of description, the cross-sectional views showing the device structures will be enlarged locally not in accordance with the general ratio, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0045] Please refer to the attached Figure 1 , Figure 3 , Figures 5 to 6 As shown, this embodiment provides a tissue separator for lung clinical use, including;

[0046] A main body 10, one side of the main body 10 is fixedly connected with a guide wire tube 12, one end of the guide wire tube 12 away from the main body 10 is provided with a negative pressure port 18, the outer edge of the negative pressure port 18 is sleeved with a rotating tube 15, and a scalpel 17 is arranged on the rotating tube 15;

[0047] Pushing component 20, the pushing component 20 includes two sets of rotating plates 21. The two sets of rotating plates 21 are rotatably connected to both sides of the end of the guide wire tube 12 far from the main body 10 through ball bearings. And a pushing plate 24 is hinged in the inner cavity of each of the two sets of rotating plates 21. A second guide wire 25 is fixedly connected to the side of each of the two pushing plates 24 far from the guide wire tube 12. And the other ends of the two second guide wires 25 extend into the guide wire tube 12 and are slidably connected inside the guide wire tube 12;

[0048] Driving component 30, the driving component 30 is arranged at the end of the main body 10 far from the guide wire tube 12. The driving component 30 includes a moving plate 32, and the moving plate 32 is fixedly connected to the other end of the second guide wire 25;

[0049] Among them, the pushing plate 24 has two forms. In the initial form, the pushing plate 24 fits against the outside of the guide wire tube 12. In the open state, the second guide wire 25 moves along the inner cavity of the guide wire tube 12, pulling the pushing plate 24 to open. And the rotating plate 21 is used to control the orientation of the pushing plate 24;

[0050] The rotating tube 15 drives the surgical knife 17 to move circularly along the negative pressure port 18.

[0051] It should be noted that a groove for facilitating holding is provided above the main body 10, aiming to facilitate the surgeon to choose a comfortable holding posture for the operation;

[0052] The outer edges of the pushing plates 24 are all rounded to avoid damaging the tissues in the patient's body during the pushing process;

[0053] The entrance of the negative pressure port 18 is a conical structure, and barbs are provided on the inclined surface of the conical structure, aiming to limit the movement of the outer skin tissue when the outer skin tissue fits above the inclined surface structure;

[0054] Multiple sets of vertical edge treatments are made on the edge of the entrance of the negative pressure port 18, and the cutting edges of the edges face the inside of the negative pressure port 18. Aiming to make the negative pressure port 18 adsorb and fix the tissue, when performing the action of pulling the tissue, the edges can move in the opposite direction to the tissue, and can cut the outer skin of the pulled tissue in advance, relaxing the adsorbed tissue, and avoiding the tissue from being too tight when being pulled, resulting in too large an incision area during the subsequent resection process.

[0055] In this embodiment, when in use, the guide wire tube 12 is inserted into the patient's body. Then, the moving plate 32 is pulled to drive the second guide wire 25 to move along the inner cavity of the guide wire tube 12, pulling and pushing the push plate 24 to rotate and open outward. At the same time, the rotating plate 21 rotates to control the orientation of the push plate 24, so that the push plate 24 pushes open the lung tissue near the separation site, avoiding blocking the separated part and affecting the separation operation. When the push plate 24 opens to an appropriate angle, the driving assembly 30 fixes the position of the push plate 24, drives the negative pressure port 18 to fit the outer skin of the lung tissue, and then the rotating tube 15 drives the surgical knife 17 to move circularly along the negative pressure port 18 to cut the outer skin tissue. After cutting, the guide wire tube 12 is pulled outward to create a gap between the outer skin and part of the tissue and the inside of the lung tissue. Then, the surgical knife 17 adjusts its inclination angle so that it can cover the center of the negative pressure port 18 and moves circularly again to cut off the tissue outer skin and part of the tissue to be removed. Finally, the guide wire tube 12 is pulled outward to take out the lung tissue.

[0056] Secondly, please refer to Figures 1 to 5 again. A handle 11 is fixedly connected to the lower end of the main body 10. A rotating handle 13 is hinged to the front of the main body 10. A hollow motor 14 is fixedly installed in the inner cavity of one end of the guide wire tube 12 away from the main body 10, and the rotating tube 15 is installed in the inner ring of the hollow motor 14.

[0057] It should be noted that the rotating handle 13 is composed of a rotating head and a fastening bolt for fastening the rotating handle 13, aiming to drive the rotation of the rotating plate 21 by rotating the handle. When adjusted to an appropriate position, the rotating handle 13 can be fixed by rotating the fastening bolt, thereby restricting the rotation of the rotating head.

[0058] A storage battery (not shown in the figure and a common technical structure in the prior art, so no further description is given here) is assembled in the inner cavity of the guide wire tube 12, and the storage battery is electrically connected to the mains electricity, aiming to facilitate the power supply to the hollow motor 14.

[0059] In this embodiment, when in use, the rotation of the push plate 24 and the rotating plate 21 is controlled by rotating the rotating handle 13, and the rotating tube 15 and the surgical knife 17 are driven to move circularly by the hollow motor 14.

[0060] Preferably, to ensure the normal use of the device, it should be used in cooperation with an endoscope device during use, and the operation is guided by the endoscope device to facilitate finding and positioning the tissue to be separated.

[0061] Secondly, please refer to Figures 3 to 5 again. A driving motor 16 is installed in the inner cavity of the rotating tube 15. The output shaft of the driving motor 16 penetrates through the rotating tube 15 and is located outside the rotating tube 15. The surgical knife 17 is fixedly connected to the outer end of the output shaft of the driving motor 16. A negative pressure tube 19 is fixedly connected to the lower end of the main body 10, and the negative pressure tube 19 is communicated with the negative pressure port 18.

[0062] The scalpel 17 is connected to the output shaft of the drive motor 16 through a bolt structure, facilitating subsequent disassembly and maintenance.

[0063] It should be noted that a contact power supply ring is provided between the rotating tube 15 and the guide wire tube 12 (not shown in the figure and is a common technical structure in the prior art, so it will not be elaborated here), which facilitates power supply to the drive motor 16.

[0064] Preferably, to ensure the normal use of the device, a negative pressure device should be externally connected during use, and the negative pressure device is communicated with the negative pressure tube 19, aiming to generate negative pressure at the negative pressure port 18 by using the negative pressure device during lung tissue resection, so as to adsorb the outer skin of the lung tissue.

[0065] In this embodiment, during the separation operation, the drive negative pressure port 18 is attached to the outer skin of the lung tissue to be resected. Immediately afterwards, the negative pressure tube 19 operates to adsorb, causing negative pressure to be generated at the negative pressure port 18. At this time, the outer skin of the lung tissue is sucked into the negative pressure port 18. Immediately afterwards, the drive motor 16 drives the scalpel 17 to be obliquely attached to the outer skin of the lung tissue. Subsequently, the hollow motor 14 drives the rotating tube 15 and the scalpel 17 to perform a circular motion, cutting open the outer skin of the lung tissue. Immediately afterwards, the guide wire tube 12 is pulled outwards, creating a gap between the outer skin and part of the tissue of the lung tissue and the interior of the lung tissue. Subsequently, the drive motor 16 adjusts the inclination angle of the scalpel 17 again, enabling the scalpel 17 to cover the center of the negative pressure port 18, and driving the scalpel 17 to perform a circular motion again, cutting off the separated outer skin and part of the tissue of the lung tissue, thereby achieving precise resection of the lung tissue.

[0066] Secondly, please refer to Figures 5 to 9 again. One end of each of the two rotating plates 21 close to the guide wire tube 12 extends into the inner cavity of the guide wire tube 12. The pushing and separating assembly 20 further includes two turntables 22, which are respectively fixedly connected to one end of the two rotating plates 21 extending into the inner cavity of the guide wire tube 12, and guide wires 23 are fixedly connected to the upper and lower ends of the outer edges of the two turntables 22.

[0067] It should be noted that the first guide wire 23 is divided into two sections. One end of each of these two sections of the first guide wire 23 is fixedly connected to the upper and lower ends of the outer edge of the turntable 22. At the same time, the other ends of the two sections of the first guide wire 23 are both fixedly connected to another rotating head of the rotating handle 13, and the parts of the two sections of the first guide wire 23 arranged inside the rotating handle 13 are fixed inside the rotating head of the rotating handle 13 through opposite winding directions, aiming to form a closed-loop circuit with the two sections of the first guide wire 23 through the turntable 22 and the rotating handle 13. In this way, when the rotating head of the rotating handle 13 rotates forward or backward, the rotation direction of the turntable 22 can be effectively controlled (because the two sections of the first guide wire 23 are fixed to the rotating head of the rotating handle 13 in opposite winding directions, when the rotating head rotates, one section will be retracted and the other section of the first guide wire 23 will be released), thereby driving the rotation direction of the turntable 22, which is convenient for operation;

[0068] The diameter of the turntable 22 is larger than the part where the rotating plate 21 is connected to the guide wire tube 12, aiming to enable the turntable 22 to play a limiting role and prevent the rotating plate 21 from detaching from the guide wire tube 12.

[0069] Here, when controlling the rotation of the rotating plate 21 and adjusting the orientation of the pushing plate 24, the extension length of the second guide wire 25 needs to be synchronously adjusted to prevent the pushing plate 24 from automatically opening due to the pulling force when the second guide wire 25 is pulled during the adjustment of the orientation of the pushing plate 24.

[0070] In this embodiment, before driving the pushing plate 24 to perform a pushing action, according to the position of the tissue to be pushed, the rotating handle 13 is controlled to rotate, driving the two ends of the first guide wire 23 to slide inside the guide wire tube 12, and then driving the turntable 22 to rotate. The turntable 22 drives the rotating plate 21 and the pushing plate 24 to rotate, adjusting the orientation of the pushing plate 24, and then different positions of the tissue can be pushed, facilitating the operation of the surgery.

[0071] Please refer to again Figures 6 to 7 The pushing-away assembly 20 further includes two groups of magnetic attraction plates 26. The two groups of magnetic attraction plates 26 are respectively fixedly connected to the inner cavities of the two groups of rotating plates 21, and the two groups of magnetic attraction plates 26 are respectively in contact connection with the two groups of pushing plates 24. A magnetic attraction component adapted to the magnetic attraction plates 26 is embedded on the side of the pushing plate 24 close to the magnetic attraction plates 26, aiming to enable the pushing plate 24 to be adsorbed inside the rotating plate 21 through the action of magnetic attraction in the normal state.

[0072] Preferably, in order to effectively reduce the force required for the pushing plate 24 to disengage from the magnetic attraction plate 26 and the rotating plate 21, a silicone layer with a thickness in the range of 0.1 to 0.3 millimeters can be provided outside the magnetic attraction component of the pushing plate 24. Through this design, the silicone layer will undergo elastic deformation when subjected to pressure, thereby reducing the effective contact area between the magnetic attraction component and the magnetic attraction plate 26. Such an improvement can reduce the force required for the pushing plate 24 to disengage by approximately 30% to 50%. Therefore, under normal conditions, the pushing plate 24 can be adsorbed by magnetic force and remain stable inside the rotating plate 21. When it is necessary to rotate and move the pushing plate 24 outward, the operator only needs to apply a relatively small pulling force, and the pushing plate 24 can easily disengage, thus greatly improving the portability of the entire operation process.

[0073] In this embodiment, under normal conditions, the magnetic attraction plate 26 adsorbs and fixes the pushing plate 24 inside the rotating plate 21 by magnetic force. After the pushing plate 24 performs a pushing action, the magnetic force adsorption of the magnetic attraction plate 26 can assist the pushing plate 24 to reset.

[0074] Please refer to again Figures 10 to 12 , the driving assembly 30 further includes a limiting tube 31. The limiting tube 31 is fixedly connected to one end of the main body 10 away from the guide wire tube 12. The moving plate 32 is slidably connected to the inner cavity of the limiting tube 31. One ends of the two groups of second guide wires 25 away from the pushing plate 24 both penetrate through the guide wire tube 12 and the main body 10 and are fixedly connected to one side of the moving plate 32 close to the main body 10. Protrusions are provided at both the upper and lower ends of the moving plate 32, and the protrusions are slidably connected to the upper and lower ends of the limiting tube 31. A spring 33 is fixedly connected to one side of the moving plate 32 away from the main body 10, and the other end of the spring 33 is fixedly connected to the middle of the inner cavity of the limiting tube 31;

[0075] Bar-shaped grooves are provided at both the upper and lower ends of the limiting tube 31, and the protrusions at both the upper and lower ends of the moving plate 32 extend out of the bar-shaped grooves and are slidably connected in the bar-shaped grooves. The parts of the protrusions at both the upper and lower ends of the moving plate 32 extending out of the bar-shaped grooves are fixedly connected with inclined pull plates, aiming to push the moving plate 32 to slide in the inner cavity of the limiting tube 31 through the inclined pull plates, thereby conveniently controlling the movement of the second guide wires 25, and the inclined design is more convenient for fingers to perform pushing and pulling actions.

[0076] It should be noted that the cross-section of the limiting tube 31 is a long strip-shaped tube, and the outer edge of the moving plate 32 is in contact with the inner cavity of the limiting tube 31, aiming to enable the moving plate 32 to only slide parallelly inside the limiting tube 31, avoiding different moving distances of the two second guide wires 25 when the moving plate 32 moves and affecting the effect of pushing open the lung tissue.

[0077] In this embodiment, when performing the action of pushing aside the tissue, the moving plate 32 is pulled to move, thereby driving the second guide wire 25 to move. The pushing plate 24 is pulled and pushed open by the second guide wire 25, and the lung tissue near the separation site is pushed aside to avoid covering the separation part and affecting the separation operation. When the pushing plate 24 is opened to an appropriate angle, the spring 33 is in a compressed state at this time. The elastic force of the spring 33 acts on the moving plate 32. At this time, the moving plate 32 is slowly released. The spring 33 gradually releases its elastic force, pushing the moving plate 32 back to its original position, thereby driving the second guide wire 25 and the pushing plate 24 back to their original positions, realizing a complete and continuous pushing and retracting action, and the pushing and retracting actions can be repeated multiple times, facilitating the search and positioning of the part to be separated.

[0078] Please refer to again Figures 12 to 13 , the driving assembly 30 further includes a positioning plate 34. The positioning plate 34 is fixedly connected to the upper end of the limiting tube 31, and one side of the positioning plate 34 is close to the strip-shaped groove at the upper end of the moving plate 32. A sliding tube 35 is fixedly connected to the side of the pulling plate at the upper end of the moving plate 32 away from the main body 10. A plug rod 36 is slidably connected to the inner cavity of the sliding tube 35. One end of the plug rod 36 close to the positioning plate 34 is movably inserted into the inner cavity of the positioning plate 34;

[0079] A through groove is opened on the side of the sliding tube 35 away from the main body 10, and a rubber block is fixedly connected to the side of the plug rod 36 close to the through groove. Anti-slip grooves are provided on the surface of the rubber block, and the rubber block is slidably connected in the through groove, aiming to use the rubber block to limit the movement range of the plug rod 36 and use the anti-slip grooves to improve the smoothness of pushing and pulling the rubber block and the plug rod 36.

[0080] It should be noted that the side of the positioning plate 34 close to the strip-shaped groove is evenly provided with insertion slots, and the plug rod 36 is inserted into the insertion slots, aiming to control the moving distance of the moving plate 32 and the second guide wire 25 by inserting the plug rod 36 into the insertion slots at different positions, and then control the opening degree of the pushing plate 24;

[0081] Both the outer end of the plug rod 36 and the entrance of the insertion slot of the positioning plate 34 are provided with smooth processing, aiming to enable the plug rod 36 to be smoothly inserted into the insertion slot.

[0082] Preferably, in the normal state, there is no need to insert the plug rod 36 into the positioning plate 34. The operator can pull the moving plate 32 to drive the second guide wire 25 to move to open the pushing plate 24, push aside the tissue near the separation part, and then the operator can release the moving plate 32. The thrust of the spring 33 is used to reset the moving plate 32 and the pushing plate 24, and then a continuous pushing action can be realized, facilitating the search and positioning of the part to be separated. When the tissue near the separation part has been completely pushed aside and the separation operation needs to be performed, the position of the pushing plate 24 can be fixed by using the plug rod 36, facilitating the operator to focus on the separation operation.

[0083] In this embodiment, after fully positioning to the tissue site to be separated, the push plate 24 can be driven to be in an open state to prevent nearby tissues from affecting the separation operation during the separation process. At this time, the insertion rod 36 can be pushed into the positioning plate 34 to fix the positions of the moving plate 32 and the push plate 24, facilitating the operator to focus on the operation of the separation operation and improving the practicability.

[0084] The working principle of the present invention is as follows: When performing the lung tissue separation operation, the guide wire tube 12 is extended into the patient's thoracic cavity. Subsequently, the moving plate 32 and the second guide wire 25 are moved, and the push plate 24 is pulled open by the second guide wire 25 to push aside the lung tissue near the separation site, preventing it from covering the separation part and affecting the separation operation. Subsequently, the moving plate 32 is slowly released, and the spring 33 gradually releases its elastic force to push the moving plate 32 back to its original position, thereby driving the second guide wire 25 and the push plate 24 to return to their original positions, realizing a complete and continuous pushing and retracting action, and the pushing and retracting actions can be repeated multiple times to facilitate finding and positioning the tissue to be separated. At the same time, when performing the pushing action, the rotating handle 13 can be controlled to rotate, driving the first guide wires 23 at both ends to slide within the guide wire tube 12, thereby driving the turntable 22 to rotate. The turntable 22 drives the rotating plate 21 and the push plate 24 to rotate, adjusting the orientation of the push plate 24, and thus can push tissues at different positions. After fully positioning to the tissue site to be separated, the push plate 24 can be driven to be in an open state to prevent nearby tissues from affecting the separation operation during the separation process. At this time, the insertion rod 36 can be pushed into the positioning plate 34 to fix the positions of the moving plate 32 and the push plate 24. Immediately afterwards, the negative pressure port 18 is driven to fit against the outer epidermis of the lung tissue to be excised. Subsequently, the negative pressure tube 19 operates to generate suction, causing the negative pressure port 18 to generate negative pressure. At this time, the outer skin of the lung tissue is sucked into the negative pressure port 18. Immediately afterwards, the motor 16 is driven to tilt the surgical knife 17 against the outer epidermis of the lung tissue, and the hollow motor 14 drives the rotating tube 15 and the surgical knife 17 to perform a circular motion to cut open the outer skin of the lung tissue. Subsequently, the guide wire tube 12 is slightly pulled outwards to create a gap between the outer skin of the lung tissue and part of the tissue and the interior of the lung tissue. Then, the motor 16 is driven to adjust the tilt angle of the surgical knife 17 again so that the surgical knife 17 can cover the center of the negative pressure port 18, and the surgical knife 17 is driven to perform a circular motion again to excise the separated outer skin of the lung tissue and part of the tissue, thereby realizing the precise excision of the lung tissue. Subsequently, the guide wire tube 12 is pulled out of the patient's thoracic cavity, and the separated tissue can be taken out, realizing the integration of separation and extraction, and improving the portability and practicability.

[0085] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented by conventional means in the art without special description and limitation.
