Description

Technical Field

[0001] The present invention relates to the technical field of medical surgical instruments, in particular to a thoracoscopic cutting and stapling device for facilitating fixed tissue excision. Background Art

[0002] The core function of a thoracoscopic cutting and stapler is to establish a minimally invasive surgical channel and achieve automated suturing and closure. A thoracoscopic cutting and stapler typically consists of a body and components. The body includes a slender instrument shaft, an ergonomic grip with a safety device, a rotating mechanism that supports multiple angles of adjustment, and operating components such as a staple removal button and a return button. The components include a staple magazine with pre-loaded staples, an anvil that provides a support surface for staple formation, and a central blade that enables integrated "cutting and stapling."

[0003] When existing thoracoscopic cutting and stapling devices are shearing and suturing target tissues, their shearing and squeezing action can easily cause the target tissue to partially escape the shearing range of the jaw rod due to squeezing deformation, resulting in incomplete shearing and suturing of the target tissue, and some diseased tissues are not effectively treated. A secondary shearing and suturing operation may be required, and the secondary operation may still have the problem of incomplete treatment, which affects the treatment effect of the cutting and stapling device during surgical operations. Conventional cutting and stapling devices need to be completed with the assistance of a thoracoscope, usually through a single-hole (generally >30mm) or two-hole or three-hole incision, so that multiple instruments can be used to enter the chest cavity at the same time, which is relatively traumatic. Therefore, the research of a thoracoscopic cutting and stapling device that is easy to fix the target tissue, thereby achieving more minimally invasive and complete and thorough treatment of the target tissue through a one-time operation has become a difficult problem that needs to be solved in this field. Summary of the Invention

[0017] A method for controlling a thoracoscopic cutting and stapling device for facilitating fixed tissue resection comprises the following steps:

[0018] S100, controlling one end of the cutting and stapling device holding body as a support portion, operating the cutting and stapling device so that the cutting and stapling mechanism at the other end is driven by the support rod to move to the vicinity of the target object, and traction and fixation of the target object are performed by positioning;

[0019] S200, acquiring target information through an endoscope and transmitting it to a display screen, adjusting the self-rotation angle of the cutting and stapling device and the angle between the cutting and stapling device and the support rod based on the position and angle of the target object, so that the open end of the cutting and stapling device matches the position and angle of the target object;

[0020] S300: Operating the jaw control button on the grip body to activate the drive mechanism, controlling the drive mechanism to transmit power through the transmission mechanism inside the cutter and stapler, causing the jaw rods of the cutter and stapler to rotate and open under the drive of the transmission mechanism, controlling the grip body to advance the cutting and stapling mechanism to both sides of the target object, and adjusting the position of the cutting and stapling mechanism so that the target object is enclosed in the clamping jaws;

[0021] S400, operate the jaw control button on the grip body to start the driving mechanism, control the jaw rod to rotate toward the side where the nail magazine is located and make the first coupling head contact and close with the second coupling head, press the target object to fit with the first nail support, the second nail support and the nail magazine, control the starting cutting slider to slide in the nail magazine to push the suture nail to suture the target object, and use the cutting knife set on the cutting slider to cut the sutured position until the target object is completely out of the position, and control the cutting stapler to retract to the initial position.

[0023] The beneficial effects of the present invention are:

[0024] The cutting and stapling device of the present invention and its control method are as follows: a first nail support hinged by a spring and a second nail support connected to the jaw rod are provided in the cutting and stapling mechanism; when the jaw rod is rotated and opened, the first nail support rotates and pops out under the action of the spring prestress, so that the first nail support, the second nail support and the nail magazine are surrounded to form a nearly closed clamping opening; in the process of the cutting and stapling mechanism pushing the target object for cutting to incorporate it into the clamping opening, the first nail support can be squeezed by the target object to rotate around the spring and pressed to one side of the nail magazine to make room for a moving path; after the target object completely enters the clamping opening, the first nail support rebounds under the tension of the spring so that the path space in the exit direction is closed and blocked, so that when the jaw rod is closed, even if the target object is squeezed and deformed, it is always limited by the closed clamping opening formed between the first nail support, the second nail support and the nail magazine, and will not be squeezed out of the clamping opening, and the target object tissue can be completely and thoroughly processed through a one-time cutting and stapling operation, which greatly improves the effect and efficiency of the cutting and stapling processing and avoids the delay time of the secondary operation.

DETAILED DESCRIPTION

[0033] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0034] Example 1: A thoracoscopic cutting and stapling device for fixing tissue resection, such as Figure 1-Figure 3 As shown, it includes a gripping body 1 and a support rod 2, one end of the support rod 2 is connected to the gripping body 1, and the other end of the support rod 2 is provided with a cutting and suturing mechanism 3;

[0035] The cutting and suturing mechanism 3 includes a nail magazine 31 and a jaw rod 32 hinged on the nail magazine 31. One end of the nail magazine 31 is connected to the support rod 2, and the other end of the nail magazine 31 is connected to a first nail seat 33. The first nail seat 33 and the nail magazine 31 are hingedly connected by a spring 34. The inclination direction of the first nail seat 33 is set opposite to the inclination direction of the jaw rod 32. A second nail seat 35 is set on the surface of the jaw rod 32 close to the nail magazine 31. The second nail seat 35 is used to cooperate with the first nail seat 33 to enclose a fixed clamping opening 36.

[0036] The cutting and suturing mechanism 3 of this embodiment is provided with a first anvil 33 hinged by a spring 34 and a second anvil 35 connected to the jaw rod 32. When the jaw rod 32 rotates and opens, the first anvil 33 rotates and pops out under the action of the prestress of the spring 34, so that the first anvil 33, the second anvil 35 and the nail magazine 31 are surrounded to form a nearly closed clamping opening. In the process of the cutting and suturing mechanism 3 pushing the target object for cutting to bring it into the clamping opening, the first anvil 33 can be squeezed by the target object to rotate around the spring 34 and be pressed to one side of the nail magazine 31 to allow After the target object completely enters the clamping mouth, the first nail seat 33 rebounds under the tension of the spring 34 so that the path space in the exit direction is closed and blocked, so that when the jaw rod 32 is closed, even if the target object is squeezed and deformed, it is always limited by the closed clamping mouth formed between the first nail seat 33, the second nail seat 35 and the nail magazine 31, and will not be squeezed out of the clamping mouth. The target object tissue can be completely and thoroughly processed through a one-time cutting and suturing operation, which greatly improves the effect and efficiency of the cutting and suturing process and avoids the delay time of the secondary operation.

[0037] It should be noted that in the use of the thoracoscopic cutting and stapling device of the present invention, it is also necessary to cooperate with some auxiliary instruments for coordinated use, such as using a positioning needle 5 to enter the chest cavity, and a hook-shaped fixing piece is provided at the end of the positioning needle 5. Figure 5 The target tissue 6 shown is fixed with hooks and pulls to keep the target tissue 6 in a certain tension state, which further facilitates the operation of the cutting and stapling device. At the same time, before the cutting and stapling device and other instruments enter, the chest cavity needs to be inflated to form an artificial pneumothorax 7, so that the instruments can perform related operations therein and explore the internal situation.

[0038] Example 2: This example is based on the above example. Figure 3As shown, a first coupling head 37 is provided on the end of the first nail seat 33 close to the second nail seat 35, and a second coupling head 38 is provided on the end of the second nail seat 35 close to the first nail seat 33. The shape of the first coupling head 37 is coupled with the shape of the second coupling head 38, and a plurality of suture staples are arranged in the staple magazine 31; wherein, the first coupling head 37 and the second coupling head 38 are used to form a closed structure when the jaw rod 32 is rotated to be closed parallel to the staple magazine 31 and to fix and support the suture staples during the suturing process. During use, the cutting stapler is hinged to the opening and closing of the jaw rod 32 and the staple magazine 31, and the jaw rod 32 is controlled to maintain the rotation plane position unchanged during the rotation toward the staple magazine 31, so that the jaw rod 32 first contacts the free end of the first coupling head 37 during the rotation and maintains sliding contact between the end of the first coupling head 37, and then the jaw rod 32 is controlled to continue rotating to press the first coupling head 37 downward, so that the first nail seat 33 rotates around the end connected to the spring 34 under pressure control until the coupling end of the first coupling head 37 contacts the coupling end of the second coupling head 38 on the jaw rod 32 and completes the coupling action through shape matching, and controls the center lines of the first nail seat 33 and the second nail seat 35 to coincide with each other and be in the same straight line position, and finally adjusts the position of the jaw rod 32 so that the jaw rod 32 and the staple magazine 31 are parallel to each other to complete the control process. The anvil and the coupling head structure thereon of this embodiment enable the target tissue 6 to be fixed in the clamping port when the cutting and suturing mechanism 3 is closed. The coupling structure can be configured such that the opposing end portions of the first anvil 33 and the second anvil 35 are each half hollow and half solid, and can be coupled to form a smooth, integrated shape after being attached to each other. For example, the upper and lower halves of two square coupling heads or circular coupling heads can be coupled to form an integrated whole. The specific coupling structure can be configured as needed. The coupling structure of this embodiment makes the cutting and suturing mechanism 3 more integrated and more stable in use after closure.

[0039] Example 3: This example is based on the above example. Figure 1 、 Figure 4As shown, a puncture endoscope mechanism 4 is sleeved on the support rod 2, and a double-channel cannula head 41 is provided on the puncture endoscope mechanism 4. Two communicable channels are provided in the double-channel cannula head 41, and the channels are used to respectively connect working instruments that need to enter the chest cavity (such as an endoscope 43) and instruments that stay outside for operation or observation (such as a display screen 47). One end of the double-channel cannula head 41 is connected to a cannula 42 and an endoscope 43. The inner diameter of the cannula 42 is set to be slightly larger than the diameter of the support rod 2. The cannula 42 can be stably mounted on the support rod 2 and partially extended into the chest cavity along with the support rod 2, so that the internal situation can be observed through the operation of the endoscope 43; the dual-channel cannula head 41 is the same as the cannula 42, and is penetrated by the support rod 2 and mounted on the support rod 2. The endoscope 43 is connected to the outer surface of the cannula 42, so that it can stably fit on the cannula 42 when entering the chest cavity without tilting or falling out; the cannula 42 is used to puncture the endoscope mechanism 4 through the wound and enter the chest cavity. Preferably, the end face of the cannula 42 tip and the end face of the endoscope 43 can be set to the same inclination and the end faces are located in the same plane, so that the contact surface of the cannula 42 and the endoscope 43 when entering the wound following the support rod 2 is flatter, and the entry is smoother.

[0040] As a preferred embodiment, a dual-channel cannula head 41 is provided with a dual-channel pipe 44, which has a first pipe opening 45 formed therein. A scope connection cable 46 is disposed within the first pipe opening 45. One end of the scope connection cable 46 is connected to the endoscope 43 through the interior of the dual-channel pipe 44, and the other end of the scope connection cable 46 is connected to a display screen 47. The dual-channel pipe 44 also has a second pipe opening 48 formed therein. A trachea is disposed within the second pipe opening 48 and communicates with the cannula 42; the trachea is used to connect to an external air pump and air supply device to supply air to the chest cavity through the cannula 42. The above-mentioned auxiliary instruments for assisting in the cutting and suturing operation are integrated into the puncture endoscope mechanism 4 of the cutting and suturing device of the present invention, and can follow the support rod 2 to enter the chest cavity to work, with stronger integrity and higher convenience, overcoming the defects of the prior art that multiple incisions or a larger incision need to be made when using various auxiliary instruments, thereby greatly reducing the size of the surgical incision and can be controlled to a wound length of less than or equal to 1.5 cm. Compared with the prior art that requires an incision of at least 3 cm in size, the incision is smaller, significantly improving the patient's postoperative recovery speed and reducing the difficulty of recovery.

[0041] Example 4: This example is based on the above example. Figure 2 As shown, an adjustment elbow 21 is connected between the support rod 2 and the cutting and suturing mechanism 3. The adjustment elbow 21 is made of a flexible damping material. The adjustment elbow 21 is used to allow the cutting and suturing mechanism 3 to rotate through the flexible connection and adjust the angle between the cutting and suturing mechanism 3 and the support rod 2. In this embodiment, the flexible damping material can be:

[0042] Rubber damping materials offer excellent shock absorption capabilities. Different types of rubber, such as natural rubber, nitrile rubber, and polyurethane rubber, can provide varying damping effects depending on their hardness, density, and composition. When used in the adjustment elbow 21 between the support rod 2 and the cutting and suturing mechanism 3, their excellent damping properties can be utilized to absorb and dissipate vibration energy.

[0043] Plastic damping materials, such as polyacrylate, polyurethane, and polyvinyl butyral, can significantly enhance their damping performance by adjusting their formulation and processing. Adjustable elbows 21 can be fabricated to meet specific needs, mitigating vibration impacts on the support rod 2 and cutting and suturing mechanism 3.

[0044] Fiber composites, including materials such as carbon fiber, glass fiber, and asbestos fiber combined with a matrix such as resin, not only enhance the material's strength and stiffness but also maintain a good damping effect. They are suitable for regulating bends 21 that require both strength and damping performance, effectively reducing vibration while bearing a certain load.

[0045] Based on the above-mentioned flexible damping material type, those skilled in the art can set a transmission mechanism for driving the adjustment bend 21 to rotate and adjust the angle in the cutting and stapling device according to the technology of driving the rotation of the adjustment bend 21 of the cutting and stapling device in the prior art, thereby realizing the control of the bending degree of the adjustment bend 21 by operating the external gripping body 1 part, which will not be repeated in the present invention.

[0046] Example 5: This example is based on the above example. Figure 2 As shown, the grip body 1 is provided with a trigger handle 11, which is provided with a safety switch button 12 and a jaw control button 13; the safety switch button 12 is used to prevent the device from accidentally starting when not in operation, and the jaw control button 13 is used to control the opening and closing of the jaw rod 32 through an internal drive mechanism and transmission mechanism. As a preferred embodiment, a rotating wheel 14 is connected between the trigger handle 11 and the support rod 2. The rotating wheel 14 is fixedly connected to the support rod 2 and is rotationally connected to the trigger handle 11; the rotating wheel 14 is used to rotate the support rod 2 to adjust the rotation angle of the nail magazine 31 and the jaw rod 32.

[0047] This embodiment of the electric cutting and stapling device utilizes an electronic lockout mechanism to ensure safety in the non-operating state. The jaw control button 13 utilizes an electric drive system to achieve smoother and more precise opening and closing. The rotation adjustment mechanism is rigidly connected to the support rod 2, allowing for flexible adjustment of various rotation angles. This, combined with adjustments to other components of the cutting and stapling device, allows for seamless operation. This structure significantly improves surgical efficiency, facilitating faster angle adjustment and achieving more consistent and stable suturing quality.

[0048] Example 6: This example is a method for controlling a thoracoscopic cutting and stapling device for fixing tissue resection. Figure 1-5 As shown, the following steps are included:

[0049] S100: Control one end of the cutting and stapling device holding body 1 as a support portion, operate the cutting and stapling device so that the cutting and stapling mechanism 3 at the other end is moved to the vicinity of the target object under the drive of the support rod 2, and the target object is pulled and fixed by the positioning needle 5;

[0050] S200, acquiring target information through the endoscope 43 and transmitting it to the display screen 47, adjusting the self-rotation angle of the cutting and stapling device and the angle between the cutting and stapling device and the support rod 2 based on the position and angle of the target object, so that the open end of the cutting and stapling device matches the position and angle of the target object;

[0051] S300: Operating the jaw control button 13 on the grip body 1 to activate the drive mechanism, controlling the drive mechanism to transmit power through the transmission mechanism inside the cutter and stapler, causing the jaw rods 32 of the cutter and stapler to rotate and open under the drive of the transmission mechanism. The grip body 1 is controlled to advance the cutting and stapling mechanism 3 to move to both sides of the target object, and the position of the cutting and stapling mechanism 3 is adjusted so that the target object is enclosed in the clamping jaws.

[0052] S400, operate the jaw control button 13 on the gripping body 1 to start the driving mechanism, control the jaw rod 32 to rotate toward the side where the nail magazine 31 is located and make the first coupling head 37 contact and close with the second coupling head 38, press the target object to fit with the first nail support 33, the second nail support 35 and the nail magazine 31, control the starting cutting slider to slide in the nail magazine 31 to push the suture nail to suture the target object, and use the cutting knife set on the cutting slider to cut the sutured position until the target object is completely out of the position, and control the cutting stapler to retract to the initial position.

[0053] The control method of the present invention establishes a stable spatial reference system through the coordinated action of the support rod 2 and the positioning pin 5 during the initial positioning phase, ensuring that the instrument tip always maintains the optimal relative position with the target tissue 6, thus avoiding clamping offset caused by instrument drift. The endoscope 43's visual system dynamically corrects the instrument angle through real-time image feedback, ensuring that the clamping opening and closing planes achieve ideal coincidence with the tissue cutting plane, effectively eliminating positioning errors caused by visual blind spots. The progressive opening process of the jaw rods 32 utilizes a step-by-step strategy, first ensuring that the tissue is fully within the clamping range through wide positioning, and then achieving precise wrapping through fine-tuning, implementing a "capture first, tighten later" logic, thereby preventing the tissue edge from being squeezed and partially dislodged from the effective cutting and suturing area. The coordinated configuration of the staple cartridge 31 and the staple holder ensures that the staples remain perpendicular to the tissue plane upon firing, and the synchronous follow-up movement of the cutting blade creates a continuous process of pressing, suturing, and cutting. This process is completed continuously through the structure of the cutter and stapler, eliminating the risk of tissue dislocation caused by step-by-step operation.

[0054] The control method of the present invention ensures that the tissue is in a stable constrained state throughout the entire suturing and cutting process through the mechanical self-locking function of the clamping mouth in the fully closed state; through the control of the electric drive, the operator's operating intention is converted into an accurate mechanical action sequence, which not only retains the flexibility of human judgment but also eliminates the uncertainty of manual operation, ultimately achieving a dual improvement in the thoroughness of tissue processing and surgical safety.

[0055] Preferably, the specific method of controlling the jaw rod 32 to rotate toward the side where the nail magazine 31 is located and making the first coupling head 37 and the second coupling head 38 contact and close in S400 can refer to the technical solution in Example 2. During preoperative preparation, the cutting stapler should be operated to check whether the coupling between the first coupling head 37 and the second coupling head 38 is well closed. At the same time, check whether the first nail support 33 and the second nail support 35 are connected to achieve good parallelism with the nail magazine 31 to ensure that the suture staples in the nail magazine 31 can be well supported and the neatness of the suture is guaranteed.

[0056] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
