Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a hemostatic instrument tip, a universal hemostatic instrument, and a laparoscopic surgical system. Background Technology

[0002] Bleeding is a frequent and unavoidable occurrence during laparoscopic surgery. Significant bleeding not only impairs the surgeon's field of vision and interferes with normal surgical procedures, but can also lead to hemorrhagic shock, postoperative anemia, impaired wound healing, and even endanger the patient's life.

[0003] Common methods for controlling bleeding during laparoscopic surgery include pressure hemostasis, electrocoagulation hemostasis, pharmacological hemostasis, and clamping hemostasis. Pressure hemostasis involves applying pressure to the bleeding point or oozing area with gauze or other instruments to stop the bleeding; electrocoagulation hemostasis utilizes the thermal effect generated when a high-frequency current comes into contact with the body to form coagulated tissue, thereby achieving hemostasis; pharmacological hemostasis involves administering hemostatic drugs to the patient to enhance the patient's own coagulation factors or inhibit anticoagulation factors to promote coagulation and achieve hemostasis; clamping hemostasis involves using surgical instruments to clamp the bleeding vessel to achieve hemostasis.

[0004] In clinical practice, surgeons need to quickly locate the bleeding site and select different hemostasis methods based on the specific bleeding condition. When the bleeding point or oozing area cannot be determined promptly, pressure hemostasis is generally used first for rapid and effective hemostasis. However, since the hemostatic effect of pressure hemostasis is not long-lasting, it needs to be combined with methods such as drug hemostasis, electrocoagulation hemostasis, and clamping hemostasis to achieve complete hemostasis. In addition, when there is excessive blood accumulation at the target site, it is necessary to spray physiological saline to clean the target site. The above surgical methods all require different medical instruments or tools. Using multiple surgical methods means frequently changing the corresponding medical instruments or tools, which increases both surgical costs and prolongs surgical time. Summary of the Invention

[0005] Based on this, the present invention provides a hemostatic instrument tip, a universal hemostatic instrument, and a laparoscopic surgical system. The hemostatic instrument tip can combine multiple hemostatic functions with functions such as cleaning and observation. Only the hemostatic instrument tip of the present invention is needed to complete multiple steps of hemostasis during surgery, effectively reducing the number of instrument changes and shortening the operation time.

[0016] In some embodiments, the distal end of the hemostatic instrument further includes a driving component that is drivenly connected to the limiting component, the driving component causing the limiting component to move relative to the hemostatic component.

[0017] In some embodiments, the driving component includes a traction member connected to the limiting component, the traction member distancing the limiting component from the distal end of the hemostatic body.

[0018] In some embodiments, a reset component is provided in the limiting channel of the limiting component, the reset component connects the limiting component to the fixing component, and the reset component has a tendency to move the limiting component toward the distal end of the hemostatic body.

[0029] Beneficial effects

[0030] The distal end of the hemostatic device of the present invention controls the relative movement of the limiting component, the fixing component, and the hemostatic component, so that the distal ends of the multiple hemostatic bodies of the hemostatic component change between a closed state and a separated state. When the multiple distal ends are in the closed state, the force application area is more concentrated, so the bleeding site can be pressed to stop the bleeding. When the multiple distal ends are in the separated state, they can be aligned with the bleeding site and then closed. During the closing process, the multiple distal ends can clamp the bleeding site, thereby achieving the effect of clamping hemostasis. Attached Figure Description

[0057] See Figure 1 , Figure 2 , Figure 1 A schematic diagram of the distal end of a hemostatic instrument according to an embodiment of the present invention is shown. Figure 2 This is an axial sectional view of the distal end of a hemostatic device according to an embodiment of the present invention. The distal end of the hemostatic device provided in this embodiment includes a hemostatic component 1, a limiting component 2, and a fixing component 3. For example... Figure 5 The diagram shown is an enlarged view of hemostasis component 1. Figure 1 , Figure 5 As can be seen, the hemostatic component 1 includes multiple hemostatic bodies 10, which are arranged at intervals in the circumferential direction. The number of hemostatic bodies 10 can be, for example, 2, 3, 4, 5, 6 or more. However, it should be noted that the circumferential direction here does not mean that these hemostatic bodies 10 must form a complete ring. In some embodiments, these hemostatic bodies 10 can also form a 3 / 4 ring or even a 1 / 2 ring.

[0058] like Figure 2 As shown, the hemostatic body 10 includes opposing proximal ends 101 and distal ends 102. The proximal ends 101 of the plurality of hemostatic bodies 10 are connected to the fixing component 3, while the distal ends 102 of the plurality of hemostatic bodies 10 are separated from each other. For example, the hemostatic component 1 can be in the form of... Figure 1 , Figure 5 The cone shape is shown. The distal end 102 of the hemostatic body 10 is also provided with a clamping part 1021 for clamping hemostasis and a pressing part 1022 for pressing hemostasis.

[0059] like Figure 4 The diagram shows a cross-sectional view of the limiting component 2 in a partial embodiment. The limiting component 2 has a limiting channel 20, and an opening 201 is formed at one end of the limiting channel 20. The opening 201 of the limiting channel 20 can limit the hemostatic body 10 of the hemostatic component 1. When the limiting channel 20 limits the distal end 102, as... Figure 3 As shown, multiple distal ends 102 approach each other and close together, multiple clamping parts 1021 cooperate to achieve clamping hemostasis, and multiple pressing parts 1022 can achieve pressing hemostasis.

[0060] When the limiting channel 20 does not limit the remote end 102, such as Figure 2 As shown, the multiple distal ends 102 will move away from each other. At this time, the clamping part 1021 is in a clamping state, that is, waiting for the bleeding site to be inserted between the multiple distal ends 102 so that the clamping part 1021 can clamp the bleeding site.

[0061] Specifically, to achieve the clamping hemostasis function, at least two clamping parts 1021 need to be close to each other to form a cooperation, while the pressing hemostasis function does not depend on the cooperation between multiple pressing parts 1022. In some embodiments, regardless of whether the distal ends 102 are close to or far from each other, the pressing part 1022 of each hemostatic body 10 can independently perform pressing hemostasis.

[0062] The distal end of the hemostatic instrument of the present invention, by simultaneously providing a clamping part 1021 for clamping hemostasis and a pressing part 1022 for pressing hemostasis on the distal end 102 of the hemostatic body 10 of the hemostatic component 1, and by configuring these distal ends 102 to be controlled by the limiting channel 20 to move closer or further apart, enables the distal end of the hemostatic instrument of the present invention to simultaneously achieve the functions of pressing hemostasis and clamping hemostasis. Compared with the prior art where a hemostatic instrument can only perform pressing hemostasis or clamping hemostasis alone, the distal end of the hemostatic instrument of the present invention can achieve pressing hemostasis and clamping hemostasis with one instrument, effectively reducing the number of instrument changes, shortening the operation time, and the combination of these two hemostatic methods can control the bleeding at the target location earlier, truly achieving twice the result with half the effort.

[0063] Understandably, there are various feasible technical solutions for how the distal ends 102 of the hemostatic bodies 10 approach and move away from each other. For example, the multiple hemostatic bodies 10 of the hemostatic assembly 1 can refer to the design of a robotic gripper, and achieve closing and opening by synchronously driving the hemostatic bodies 10 towards or away from each other through a gear transmission mechanism, etc. However, since the hemostatic device tip is a medical device that needs to be inserted into the human body, the structural design of the hemostatic device tip should be as restrained and simple as possible. In some embodiments, the hemostatic body 10 is configured as an elastic element. That is, by utilizing the elasticity of the hemostatic body 10, when the hemostatic body 10 is limited by the limiting channel 20 of the limiting assembly 2, the multiple hemostatic bodies 10 will approach each other due to compression, and when the hemostatic body 10 is not limited by the limiting channel 20, the hemostatic body 10 will spontaneously return to a state of moving away from each other due to its own elasticity. The hemostatic body 10 with this elastic element can eliminate the need for a transmission mechanism, thereby simplifying the structure of the hemostatic device end of the present invention while ensuring that the multiple hemostatic bodies 10 can close and open.

[0064] Furthermore, the cooperation between the elastic hemostatic body 10 and the limiting channel 20 specifically means that the proximal ends 101 of the multiple hemostatic bodies 10 are located within the limiting channel 20, and the hemostatic bodies 10 can reciprocate along the limiting channel 20. When the proximal ends 101 move away from the distal ends 102, the multiple distal ends 102 are limited by the limiting channel 20 and move closer to each other, and the hemostatic assembly 1 closes. When the proximal ends 101 move towards the distal ends 102, the multiple distal ends 102 move away from each other, and the hemostatic assembly 1 opens. In this embodiment, the method of making the multiple hemostatic bodies 10 move closer or further apart is simple, requiring only relative movement between the limiting component 2 and the hemostatic assembly 1. The operation is simple and intuitive, and it can stably achieve the effect of the hemostatic bodies 10 moving closer or further apart. The distal end of the hemostatic device of the present invention has high stability and meets clinical needs.

[0065] Obviously, the material selection for the hemostatic body 10 of the elastic element at the end of the hemostatic device of the present invention is not limited. For example, it can be a metal such as stainless steel or steel, or a non-metal such as polyetherimide (PEI), polyethylene (PE), or nylon. The hemostatic body 10 can be set as a thin sheet with a thickness of not less than 0.1 mm.

[0066] Understandably, there are various ways to achieve the ability of multiple clamping portions 1021 to cooperate in forming clamping hemostasis. In some embodiments, the clamping portion 1021 refers to the side facing each other between the distal ends 102 of adjacent hemostatic bodies 10 in the circumferential direction, that is, clamping hemostasis is formed between adjacent distal ends 102 in the circumferential direction.

[0067] In other embodiments, such as Figure 6As shown, the clamping portion 1021 includes a clamping surface facing the axis of the hemostatic component 1, and the pressing portion 1022 includes a pressing surface facing away from the proximal end 101. With this configuration, when the distal ends 102 approach each other, the clamping portions 1021 of the multiple distal ends 102 can form a clamping hole, the diameter of which can be, for example, 0.5mm-10mm. This clamping hole can clamp the bleeding site to achieve hemostasis. Preferably, the clamping surface can be set as an arc surface, which can form a smoother clamping hole, reducing damage to the tissue caused by clamping. Similarly, when the distal ends 102 approach each other, the pressing portions 1022 of the multiple distal ends 102 can form a continuous, large pressing surface suitable for pressing the bleeding site, through which the bleeding site can be pressed to achieve pressure hemostasis. In this regard, it is preferable that the pressing surfaces of multiple hemostatic bodies 10 form a plane or an outwardly protruding convex surface, and the plane or convex pressing surface is conducive to improving the hemostatic effect of pressing.

[0068] It is readily understood that the hemostatic device tip of the present invention does not limit the specific structure of the hemostatic body 10 of the hemostatic component 1. As a partially achievable example, such as... Figure 5 As shown, the hemostatic body 10 includes a first extension 11 and a second extension 12. One end of the first extension 11 is the proximal end 101, and the other end of the first extension 11 is connected to the second extension 12. The end of the second extension 12 that is not connected to the first extension 11 is the distal end 102. The distance from the connection point of the second extension 12 and the first extension 11 to the axis of the hemostatic assembly 1 is greater than the distance from the distal end 102 to the axis of the hemostatic assembly 1. This arrangement allows the hemostatic assembly 1 to have a small overall size while ensuring sufficient space for the distal ends 102 to be separated from each other.

[0069] Specifically, such as Figure 2 , 4 As shown, the cross-sectional contours of the first extension segment 11 and the second extension segment 12 along their length are monotonic curves, and the first extension segment 11 and the second extension segment 12 form an angle of less than 180°, which can be an acute angle, a right angle, or an obtuse angle. The monotonic curve form of the first extension segment 11 and the second extension segment 12 makes them easier to manufacture, allows for more direct force transmission, and results in better stability for the hemostatic body 10 constructed from these first extension segments 11 and the second extension segment 12. As a specific example, the first extension segment 11 can be configured as a straight line, with an angle of not less than 10° between it and the axis of the hemostatic component 1, and the distance from the connection point of the second extension segment 12 and the first extension segment 11 to the axis is not less than 3 mm. This design meets the size requirements of laparoscopic surgery and enables the hemostatic instrument of the present invention to have good clamping and pressure-based hemostasis capabilities.

[0070] In some embodiments, such as Figure 4As shown, the limiting component 2 is tubular, with a limiting channel 20 extending along its length inside. Preferably, the opening 201 of the limiting component 2 is configured such that its inner wall conforms to the outer contour of the hemostatic component 1. For example, when the hemostatic component 1 is conical, the inner wall of the opening 201 is a conical surface. In this way, when the opening 201 limits the hemostatic body 10 of the hemostatic component 1, the restraining force on the hemostatic body 10 is uniform, and the opening 201 can better clamp and release the hemostatic body 10 of the hemostatic component 1.

[0071] In order to allow relative movement between hemostatic component 1 and limiting component 2, such as Figure 2 As shown, the distal end of the hemostatic device of the present invention further includes a driving component 6, which is drivenly connected to the limiting component 2 and is capable of driving the limiting component 2 to move relative to the hemostatic component 1. Specifically, the driving component 6 includes a traction member 61 connected to the limiting component 2, which moves the opening 201 of the limiting channel 20 away from the distal end 102 of the hemostatic body 10. In other words, the traction member 61 can move the distal end 102 of the hemostatic body 10 away from the limiting component 2, causing the distal end 102 to change from a closed state to a separated state.

[0072] Since the hemostatic instrument tip of the present invention is mainly applicable to laparoscopic surgery, its overall size must be small enough. Therefore, each structure of the hemostatic instrument tip must be sufficiently simplified. The traction member 61, while enabling relative movement between the limiting component 2 and the hemostatic body 10, is also structurally simple, making it very suitable for the application scenarios of the hemostatic instrument tip of the present invention. The reason for using the traction member 61 to drive the limiting component 2 instead of the hemostatic component 1 is that the hemostatic component 1 is the part that directly contacts the bleeding site. Only by ensuring that the position of the hemostatic component 1 is relatively fixed can the surgeon use the hemostatic instrument tip of the present invention to clamp and press on the bleeding site with minimal interference.

[0073] In some embodiments, such as Figure 7 As shown, the drive assembly 6 also includes a fixed connector 62 extending through the limiting assembly 2 along a direction perpendicular to the limiting channel 20. One end of the traction member 61 is fixed to the fixed connector 62, and the other end is connected to one of the drive wheels (joints) of the instrument box. When the drive wheel of the instrument box rotates, it pulls the traction member 61, the fixed connector 62, and the limiting assembly 2 in sequence, causing the distal end 102 of the hemostatic body 10 of the hemostatic assembly 1 to move away from the limiting assembly 2 and separate from each other. For example, the fixed connector 62 can be a pin, and the traction member 61 can be a traction tungsten wire. By setting the fixed connector 62 to extend through the limiting assembly 2 perpendicular to the limiting channel 20, the force applied by the traction member 61 to the fixed connector 62 can be completely converted into a force pulling the limiting assembly 2, without any additional force consumption, thus improving power.

[0074] like Figure 2 As shown, in some embodiments, the hemostatic instrument of the present invention is further provided with a reset component 7 within the limiting channel 20 of the limiting component 2. The reset component 7 connects the limiting component 2 to the hemostatic component 1 and has a tendency to move the limiting component 2 toward the distal end 102. With the help of the reset component 7, even if the limiting component 2 is subjected to a certain degree of unexpected external force, the reset component 7 can keep the limiting channel 20 of the limiting component 2 in a closed state, limiting the distal end 102 of the hemostatic component 1.

[0075] As a specific example, such as Figure 2 , Figure 4 As shown, the fixing component 3 is provided with a first limiting structure 31, and the limiting component 2 is provided with a second limiting structure 21 in the limiting channel 20. The distance from the first limiting structure 31 to the opening 201 is greater than the distance from the second limiting structure 21 to the opening 201. The two ends of the resetting component 7 abut against the space between the first limiting structure 31 and the second limiting structure 21. More specifically, as shown... Figure 8 As shown, the fixing component 3 can be tubular, with a limiting tube serving as the first limiting structure 31 fitted onto one end away from the proximal end 101. This limiting tube is used to connect with the connecting component 5. Figure 4 As shown, a limiting step serving as the second limiting structure 21 is formed within the limiting channel 20; the reset component 7 is a spring, which is sleeved on the tubular fixing component 3, with its two ends abutting against the step surface of the limiting step and the end face of the limiting tube, respectively. Since the two ends of the limiting component 2 at the end of the hemostatic instrument need to respectively bear the functions of hemostasis and connecting the instrument rod, placing the reset component 7 in a relatively middle position at the end of the hemostatic instrument can make full use of the space on the end of the hemostatic instrument, giving the end of the hemostatic instrument better stability.

[0076] like Figure 9As shown, in some embodiments, the limiting component 2 can also be detachably connected to a transmission component 22, which is then connected to a drive component 6 (e.g., a traction member 61). Again, taking the limiting component 2 as a tubular example, in this embodiment, the transmission component 22 is a transmission tube embedded within the tubular limiting component 2. The transmission tube and the limiting component 2 can be in a snap-fit ​​relationship; for example, the transmission tube has snap-fit ​​protrusions, and the limiting component 2 has snap-fit ​​grooves that mate with the snap-fit ​​protrusions. In this embodiment, the transmission tube has a fixing hole for fixing the aforementioned pin. The pin can be fixed to the transmission tube, and the traction wire pulls the transmission tube, causing the limiting component 2 to move relative to the fixing component 3. By setting the limiting component 2 and the traction member 61 as an indirect connection, the hemostatic device tip of the present invention no longer requires special processing of the limiting component 2 to connect with the traction member 61, reducing processing difficulty. Furthermore, the outer surface of the limiting component 2 can remain intact, preventing bodily fluids from adhering to the connection between the drive component 6 and the limiting component 2 after use, thus reducing the cleaning difficulty of the hemostatic device tip of the present invention.

[0077] It is understood that the specific form of the fixation component 3 at the distal end of the hemostatic device of the present invention is not limited. For example... Figure 10 In some embodiments, the fixing component 3 is configured as a tubular shape that matches the limiting channel 20. This configuration creates a radial constraint between the fixing component 3 and the limiting channel 20, ensuring that the hemostatic component 1 moves stably relative to the limiting component 2, and that the multiple distal ends 102 can retract uniformly towards the axis of the hemostatic component 1. In some embodiments, the sidewall of the fixing component 3 may also have an elongated hole 32 parallel to the direction of the limiting channel 20, so that the fixing connector 62 can slide smoothly relative to the fixing component 3.

[0078] To further reduce the number of instrument changes during laparoscopic surgery and improve surgical efficiency, such as Figure 11 , Figure 12 As shown, the hemostatic device tip of the present invention also includes a functional component. The functional component is installed at the end where the fixing component 3 is connected to the hemostatic component 1, and is arranged to be surrounded by a plurality of hemostatic bodies 10 of the hemostatic component 1. With this arrangement, when the hemostatic device tip of the present invention uses the hemostatic component 1 to clamp and press to stop bleeding tissue, the functional component can further process the bleeding tissue. Thus, the hemostatic device tip of the present invention can perform other actions simultaneously while performing pressing and clamping hemostasis, greatly enriching the function of the hemostatic device tip of the present invention and expanding the application scenarios of the hemostatic device tip of the present invention.

[0079] Obviously, the hemostatic device tip of the present invention does not specifically limit how the functional components are mounted on the fixing component 3, as long as the fixing component 3 has sufficient space to allow the functional components to be installed and to communicate with the outside. In some embodiments, such as Figure 1 As shown, the fixing component 3 is provided with a connecting channel 30 parallel to the limiting channel 20. The functional component can communicate with the outside through the connecting channel 30 to realize its function.

[0080] It is understandable that those skilled in the art can select specific functional components based on the actual needs of laparoscopic surgery. For example... Figure 11 , Figure 12 As shown, in some embodiments, the functional component may include a drug delivery component 41. Specifically, the drug delivery component 41 includes a drug delivery line communicating with the outside and a drug delivery port 410. The drug delivery port is located on the distal end 102 and is connected to the drug delivery line. In this partial embodiment, when the hemostatic device of the present invention uses the clamping part 1021 and the pressing part 1022 on the distal end 102 of the hemostatic component 1 to clamp and press the bleeding site for hemostasis, such as... Figure 19 As shown, the external drug delivery device is connected to the drug delivery interface 301 on the device box 300, and the drug delivery tubing is connected to the drug delivery interface 301. Thus, hemostatic drugs can be delivered into the patient's body through the drug delivery tubing of the drug delivery component 41. The hemostatic drugs can be directly applied to the bleeding site from the drug delivery port 410 on the distal end 102, realizing the combined use of clamping hemostasis, pressure hemostasis and drug hemostasis, which improves the hemostatic effect of a single hemostatic device end of the present invention.

[0081] In other embodiments, such as Figure 11 , Figure 12 As shown, the functional components may further include an imaging component 42. The imaging component 42 may be, for example, an endoscope. In some embodiments, such as... Figure 19 As shown, the endoscope is connected to the imaging component interface 302 on the instrument box 300, and the external device is then connected to the imaging component interface 302. The hemostatic instrument tip of the present invention is mainly used in laparoscopic surgery. Before the operation limiting component 2 separates the distal end 102 of the hemostatic body 10 of the hemostatic component 1 to clamp and press the bleeding site for hemostasis, the imaging component 42 allows the surgeon to carefully observe the bleeding site. On the one hand, it can fine-tune the position of the hemostatic component 1 so that it can better clamp and press the bleeding site for hemostasis. On the other hand, it also helps the surgeon to further determine what operation to perform on the bleeding site, thus improving surgical efficiency and surgical effect.

[0082] Alternatively, in some embodiments, such as Figure 11 , Figure 12 As shown, the functional components may also include a cleaning component 44. The cleaning component 44 can be a cleaning pipe, such as... Figure 19As shown, in some embodiments, one end of the cleaning pipe is connected to the cleaning component interface 304 on the instrument box 300, and the other end forms a cleaning hole on the distal end 102. The cleaning component interface 304 is connected to an external cleaning device. Thus, the external cleaning device can use the cleaning pipe to release cleaning liquid from the cleaning hole to clean the bleeding site. In some embodiments, after the hemostatic component 1 at the end of the hemostatic instrument of the present invention clamps and presses the bleeding site to stop the bleeding, the cleaning component 44 is activated to clean the remaining blood and dirt from the bleeding site, so that other steps can be performed subsequently. Alternatively, in some embodiments, the cleaning component 44 can cooperate with the aforementioned imaging component 42. When there is a lot of blood and dirt remaining at the bleeding site and the exact location cannot be determined, the cleaning component 44 can be activated first to clean the blood and dirt from the bleeding site. The imaging component 42 can then obtain a clear image of the bleeding site for the operator to further understand the condition of the bleeding site, and then the hemostatic component 1 can be used to press and clamp the bleeding site to stop the bleeding.

[0083] like Figure 11-15 As shown, in some embodiments, the functional component may further include an electrocoagulation component 43, which includes an electrode 431 connected to the outside. When energized, the electrode 431 heats up and can electrocoagulate and stop bleeding at the bleeding site. Specifically, the electrode 431 is connected to an electrode interface 303 on the instrument box via a wire, and the electrode interface 303 is connected to an external power supply device. When the hemostatic instrument of the present invention uses the clamping part 1021 and the pressing part 1022 on the distal end 102 of the hemostatic component 1 to clamp and press the bleeding site for hemostasis, the bleeding point will be located between the hemostatic bodies 10. The electrode 431, surrounded by the hemostatic bodies 10, can directly electrocoagulate and stop bleeding at the bleeding site. The hemostatic instrument tip of the present invention, by incorporating a functional component including an electrocoagulation component 43, enables the hemostatic instrument tip of the present invention to simultaneously achieve the combined use of three hemostatic methods: pressure hemostasis, clamping hemostasis, and electrocoagulation hemostasis. This eliminates the time lag in coordinating the three hemostatic methods caused by the need to use multiple devices, providing a completely new hemostatic method for clinical use. By using the hemostatic instrument tip of the present invention, surgical efficiency and hemostatic effect can be improved.

[0084] like Figure 11 As shown, in some embodiments, electrode 431 can be selected as a hook-shaped electrode. Besides achieving electrocoagulation hemostasis, the hook-shaped electrode, with its hook-like contour, can also have a certain hooking function, enabling more operations. Obviously, in other embodiments, electrode 431 can also be shovel-shaped, etc. The specific form of electrode 431 at the end of the hemostatic device of the present invention is not limited.

[0085] Specifically, in such Figure 13In the illustrated embodiments, the electrocoagulation assembly 43 of the present invention includes a first connector 432 and a second connector 433. An electrode 431 is mounted on the end of the first connector 432 facing the hemostasis assembly 1. The second connector 433 is connected to and can slide along the connecting channel 30. The first connector 432 and the second connector 433 are connected by a serpentine skeleton 434, which can be three or more. With this configuration, the electrocoagulation assembly 43 can be relatively displaced along the connecting channel 30 of the fixed assembly 3, making the distance between the electrode 431 and the distal end 102 adjustable. Furthermore, the first connector 432 can deflect in four directions relative to the second connector 433, allowing the electrode 431 to change angle relative to the axis of the hemostasis assembly 1. In this embodiment, the electrode 431 of the electrocoagulation assembly 43 has high flexibility, enabling electrocoagulation hemostasis at different bleeding sites.

[0086] To illustrate the synergy between Snake Bone 434, please refer to [link / reference]. Figure 14 ,like Figure 14 As shown, in some embodiments, there are three snake bones 434 and four manipulation wires 4340. In this embodiment, the middle snake bone 434 has a through hole for the manipulation wires 4340 to pass through. Two manipulation wires 4340 are connected as a group to the rightmost snake bone 434 connected to the first connector 432, while the other two manipulation wires 4340 are also connected and fixed to the middle snake bone 434. The two groups of manipulation wires 4340 are respectively connected to two drive wheels on the instrument box. When the drive wheels rotate, they cause the middle snake bone 434 and the rightmost snake bone 434 to deflect, which allows the first connector 432 to deflect in four directions relative to the second connector 433.

[0087] Among them, the preferred ones are, such as Figure 15 , Figure 16 As shown, the second connector 433 includes a shaft-shaped member 4330 and a limiting slider 4331 that radially protrudes from the shaft-shaped member 4330. The shaft-shaped member 4330 is coaxial with the connecting channel 30 of the fixing assembly 3, and the shaft-shaped member 4330 is connected to the first connector 432. Figure 17 As shown, the inner wall of the connecting channel 30 of the fixing component 3 is provided with a limiting groove 33 along its length direction, and the limiting slider 4331 is located in the limiting groove 33 and can slide along it.

[0088] In this embodiment, the shaft-shaped member 4330 coaxial with the connecting channel 30 and the limiting slider 4331 extending radially therefrom enable the second connector 433 to slide very stably along the connecting channel 30, ensuring the stability of the electrocoagulation assembly 43 during use and ensuring the accuracy of the electrocoagulation hemostasis operation. On the other hand, the design of the limiting slider 4331, while ensuring the connection between the shaft-shaped member 4330 and the connecting channel 30, allows for a gap between the shaft-shaped member 4330 and the inner wall of the connecting channel 30, so that other functional components can be installed within the connecting channel 30. For example, such as... Figure 17 As shown, the axial member 4330 is symmetrically provided with two limiting sliders 4331, and the drug delivery component 41 is disposed between the two limiting sliders 4331, located in the gap between the outer surface of the axial member 4330 and the inner wall of the connecting channel 30. Therefore, the hemostatic device tip of the present invention can integrate the aforementioned drug delivery component 41, imaging component 42, cleaning component 44, and other functional components with the electrocoagulation component 43. The cooperation of these multiple functional components gives the hemostatic device tip of the present invention multiple functions, greatly improving surgical efficiency and hemostatic effect.

[0089] Specifically, in some embodiments, by providing the end of the hemostatic instrument of the present invention, the hemostatic component 1 can be used to first apply pressure to the bleeding site for hemostasis, and then clamp it for hemostasis. After a certain degree of hemostasis is achieved, the electrocoagulation component 43 can be used to completely stop the bleeding at the bleeding site, and then the cleaning component 44 can be used to clean the bleeding site. In other embodiments, after applying pressure and clamping to the bleeding site with the hemostatic component 1, before using the electrocoagulation component 43 for electrocoagulation, the drug delivery component 41 can be used to apply medication to the bleeding site for hemostasis, thereby enabling effective hemostasis for some more special bleeding situations. In the above schemes, the imaging component 42 can also be used in conjunction for observation, so that doctors can better judge and select the best means for hemostasis. In the case of the prior art, on the one hand, it is difficult for doctors to observe the bleeding site well. Nurses and doctors need to coordinate multiple devices on the operating table to accurately locate the bleeding location, which greatly increases the complexity of the operation. On the other hand, since hemostasis during surgery is very urgent, it is difficult for doctors to select and change multiple hemostatic instruments to complete hemostasis within a limited time, further increasing the difficulty of the operation. This invention integrates multiple hemostatic functions into the end of a single hemostatic instrument. Doctors can choose one or more appropriate hemostatic methods to treat the bleeding site based on a full understanding of the bleeding location, greatly reducing the difficulty of surgery, improving surgical efficiency, and achieving excellent hemostatic effects.

[0090] It should be noted that the hemostatic device tip of the present invention does not limit how the electrocoagulation component 43 is driven. This is merely an example, as shown in the figures. Figure 16As shown, the electrocoagulation assembly 43 also includes an active drive member 435 and a passive drive member 436. The active drive member 435 connects the second connector 433 to the external drive member, enabling the second connector 433 to move along a first direction. The passive drive member 436 is connected to the second connector 433, giving the second connector 433 a movement tendency opposite to the first direction. With the cooperation of the active drive member 435 and the passive drive member 436, the electrocoagulation assembly 43 can always return to its initial state after use, allowing for reuse.

[0091] Specifically, such as Figure 16 In the illustrated embodiment, the active drive member 435 can be a traction wire, one end of which is connected to the aforementioned limiting slider 4331, and the other end is connected to one of the drive wheels of the instrument box. The passive drive member 436 can be a compression spring, which is sleeved on the shaft-shaped member 4330. One end of the compression spring abuts against the limiting slider 4331, and the other end abuts against the limiting protrusion in the inner wall of the connecting channel 30 of the fixing assembly 3. Thus, when the electrode 431 needs to move away from the distal end 102, the traction wire can pull the second connecting member 433 to the left side of the illustration. When the electrode 431 needs to move back towards the distal end 102, the traction wire is released, and the compression spring can push the second connecting member 433 to the right side of the illustration.

[0092] In such Figure 1 , Figure 2 In some embodiments shown, the hemostatic instrument tip of the present invention further includes a connecting component 5. One end of the connecting component 5 is connected to the fixing component 3, and the other end of the connecting component 5 is used to connect to the instrument rod. Preferably, the connecting component 5 can be a snake-bone connector. Compared with other types of connecting components, the snake-bone connector has the ability to allow the hemostatic instrument tip to swing up and down and left and right relative to the instrument rod, and it also has sufficient space inside to accommodate the connection lines between the functional component 4 and external devices, making it very suitable for laparoscopic surgery scenarios. Specifically, when the connecting component 5 is a snake-bone connector, the operating wire for operating the snake-bone connector can also be connected to the drive wheel on the instrument box.

[0093] Another aspect of the present invention discloses a universal hemostatic device, such as Figure 18 As shown, the device includes an instrument box 300, an instrument rod 200, and any of the aforementioned hemostatic instrument tips 100. One end of the instrument rod 200 is connected to the instrument box 300, and the other end of the instrument rod 200 is connected to the fixing component 3 of the hemostatic instrument tip 100. This universal hemostatic device allows all functional components and driving elements on the hemostatic instrument tip 100 to be connected to the instrument box 300 via the instrument rod 200, thereby achieving functional integration. Only one universal hemostatic device is needed to perform multiple tasks asynchronously / synchronously, reducing surgical difficulty and improving surgical efficiency.

[0094] Since the specific structure, functional principle, and technical effects of the hemostatic instrument tip 100 have been described in detail above, they will not be repeated here. Any technical information regarding the hemostatic instrument tip 100 can be found in the preceding text.

[0095] A third aspect of this invention discloses a laparoscopic surgical system, including a surgical robot and the aforementioned universal hemostatic device, the universal hemostatic device being mounted on the robotic arm of the surgical robot. By mounting this universal hemostatic device on the surgical robot, the surgeon can remotely operate the system to perform laparoscopic surgery on patients in bed, greatly enriching the medical scenarios.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
