Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an endoscopic suture handle. Background Technology

[0002] With continuous technological innovation and development, the application of endoscopic staplers in the medical field has gradually expanded, bringing patients safer and more effective treatment methods. As a special medical device, endoscopic staplers are mainly used for suturing internal organs, such as suturing digestive tract tissues, treating gastrointestinal perforations, repairing damaged tissues, or assisting in other surgical treatments. Compared with traditional surgery, by combining with endoscopic technology, endoscopic staplers can perform high-precision suturing of patients' internal organs, avoiding the trauma and complications caused by open surgery, thereby reducing surgical risks. In addition, endoscopic stapler surgery involves smaller incisions, reducing patient pain, shortening hospital stays, and greatly improving patient recovery rates.

[0003] While existing endoscopic staplers offer certain advantages in achieving high-precision suturing and their practicality has gained some recognition, various limitations and shortcomings remain. Regarding the operating handle of the endoscopic stapler, in actual clinical use, most surgeons hold the handle with their right hand. Operating the handle drives the transmission mechanism to open and close the needle arm on the endoscopic stapler, facilitating needle grasping and release. Therefore, right-handed surgeons can better control the rhythm and progress of the surgery, completing the entire procedure more easily. However, for left-handed surgeons, this handle design increases the difficulty of use.

[0004] Furthermore, endoscopic staplers require instrument channels and wire drives to control the end effector at the insertion point, enabling it to perform specific instrumental actions such as tissue grasping, needle exchange, and suture knotting. This typically requires multiple instrument channels. Some existing products directly utilize the endoscope's own instrument channels, which renders the endoscope's suction / perfusion and biopsy functions unusable. Other existing products connect the instrument channel externally to the endoscope's handle, rather than directly to it, resulting in a separation between the channel and the handle. This leads to operational inconvenience during surgery. For example, in delicate procedures, this separation can impair the surgeon's precise control of the instruments, increasing the difficulty and risk of the operation, ultimately jeopardizing patient safety.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0039] In some comparative embodiments, the internal locking mechanism of the endoscopic stapler handle is more complex, employing multiple delicate components and a relatively complex mechanical structure. In practice, both manufacturing and assembly require a high level of expertise to ensure the locking function is achieved.

[0040] Reference Figures 1-8 As shown, this embodiment of the present invention provides an endoscopic suture handle, including a handle assembly 100, a first connector 200, an actuation wire channel 300, and a second connector 400. Wherein:

[0041] The handle assembly 100 includes a handle body 110, a first trigger 120, a slider 130, and a self-locking component 140. The first trigger 120 is rotatably connected to the handle body 110 (e.g., hinged by a pin). The slider 130 is slidably connected to one side of the handle body 110 and is connected to the first trigger 120. The first trigger 120 drives the slider 130 to move along the X-axis, which is parallel to the axis of the endoscope 500. The self-locking component 140 is connected in the handle body 110; the first trigger 120 drives the slider 130 to slide to its end, and the self-locking component 140 locks the first trigger 120.

[0042] The first connector 200 is rotatably connected to the handle body 110, and the handle body 110 rotates about the X-axis relative to the first connector 200. The first connector 200 is provided with multiple instrument channels 210, which can realize the control of the end effector of the inserted part, such as tissue grasping, needle exchange, suture knotting, etc. These instrument channels 210 are reasonably arranged to meet the needs of different instruments for passage and operation.

[0043] The actuation line channel 300 extends from the front end of the first connector 200 through the handle body 110 along the X-axis to the front side of the slider 130. An actuation cable (not shown in the figure) is inserted through the actuation line channel 300, and both ends of the actuation cable are connected to the slider 130 and the end effector (not shown in the figure), respectively. The inner wall of the actuation line channel 300 is smooth, thereby ensuring the smooth movement of the actuation cable within the actuation line channel 300.

[0044] One end of the second connector 400 forms a spherical pair with the first connector 200 via a steering ball 410, and the other end is used to connect to the endoscope 500.

[0045] Specifically, in this embodiment, the handle body 110 is rotatably connected to the first connector 200, and the endoscope 500 is connected to one side of the handle assembly 100 via the second connector 400. Thus, by rotating the handle assembly...

[0046] In addition, the self-locking component 140 provided in this application, which is connected to the first trigger 120, can lock and unlock the first trigger 120. The structure is simple, stable and reliable.

[0047] Furthermore, the handle assembly 100 also includes a first elastic element 150. The first trigger 120 is connected to the handle body 110 via the first elastic element 150. Specifically, after the self-locking component 140 is unlocked, the first elastic element 150 enables the first trigger 120 and the slider 130 to automatically reset, requiring no operator intervention and making it more convenient to use.

[0048] Furthermore, a mounting groove 121 is provided on one side of the first trigger 120; a limiting member 111 is provided on the side of the handle body 110 facing the first trigger 120, and the limiting member 111 and the mounting groove 121 form a sliding pair. A first elastic member 150 is disposed in the mounting groove 121, and one end of the first elastic member 150 is connected to the first trigger 120 and the other end is connected to the limiting member 111. Specifically, the cooperation between the mounting groove 121 and the limiting member 111 in this embodiment can provide guidance for the rotation of the first trigger 120 in the handle body 110, and on the other hand, it can limit the spring so that the extension path of the spring coincides with the rotation path of the first trigger 120, thereby ensuring that the rotation and reset of the first trigger 120 are more stable and reliable.

[0049] Furthermore, the self-locking component 140 includes a second trigger 141 and a second elastic member 142. The second trigger 141 is rotatably connected to the handle body 110 and located on one side (e.g., the rear side) of the first trigger 120; one side of the second trigger 141 and the first trigger 120 adjacent to each other has a groove 122 and the other side has teeth 143. The first trigger 120 drives the second trigger 141 to rotate to a predetermined position, and the teeth 143 engage with the groove 122. The two ends of the second elastic member 142 are respectively connected to the second trigger 141 and the handle body 110. Specifically, in this embodiment, the rotation of the first trigger 120 can drive the rotation of the second trigger 141. When the first trigger 120 rotates to the predetermined position, the engagement of the teeth 143 with the groove 122 can lock the first trigger 120, thereby facilitating operation by the operator; during this process, the operator does not need to hold the first trigger 120 continuously, so operation is more convenient.

[0050] Furthermore, the self-locking component 140 also includes two return levers 144, which are respectively disposed on both sides of the second trigger 141. The return levers 144 extend beyond the two side walls of the handle body 110. Specifically, this embodiment provides two return levers 144, and the return levers 144 extend beyond the handle body 110. Thus, the second trigger 141 can be rotated by rotating the return levers 144, facilitating the unlocking of the second trigger 141.

[0051] This application also includes a rotating shaft 600, which is rotatably connected to the first connector 200. The end of the rotating shaft 600 is connected to the handle body 110. A boss 610 protrudes outward from the outer wall of the rotating shaft 600. The end of the first connector 200 is provided with a first groove and a second groove. The first groove extends along the X-axis, and the second groove is coaxial with the first groove. The rotating shaft 600 is installed in the first groove, and the boss 610 engages with the second groove. Specifically, in this embodiment, the rotating shaft 600 and the first groove enable a rotatable connection between the first connector 200 and the handle body 110, allowing for left- or right-handed operation of the handle, thus better adapting to the user's operating habits. The engagement of the boss 610 with the second groove ensures the connection between the handle body 110 and the first connector 200, preventing the handle body 110 from shifting or wobbling. Because the handle body 110 directly affects the accuracy and safety during the operation, in order to minimize the possibility of the handle body 110 shaking during the operation, the first connector 200 has a small gap and a tight connection with the handle body 110, which improves the stability and safety of the operation and provides a strong guarantee for the successful implementation of the operation.

[0052] Furthermore, the handle body 110 is provided with a motion track 112, and the slider 130 and the motion track 112 form a sliding pair. Specifically, in this embodiment, the motion track 112 guides and limits the sliding of the slider 130, ensuring that the slider 130 slides along the required track on the one hand, and guiding the sliding of the slider 130 on the other hand, ensuring its smoothness.

[0053] Furthermore, one end of the second connector 400 is provided with a clamp 420, and the endoscope 500 is detachably connected to the clamp 420. Specifically, in this embodiment, the clamp 420 is used to realize the installation and removal of the present application and the endoscope 500, which is convenient and quick to operate.

[0054] Furthermore, the first trigger 120 is provided with a strip-shaped slot 123, and the slider 130 is disposed in the slot 123. Specifically, in this embodiment, through the cooperation of the slot 123 and the slider 130, the first trigger 120 can drive the slider 130 to move back and forth when it swings along an arc-shaped trajectory, resulting in a simple structure. During the design process, the triggering force and stroke of the first trigger 120 were repeatedly adjusted to meet the operating principle and functional requirements of the entire device.

[0055] Furthermore, the first trigger 120 includes a trigger body 124 disposed inside the handle body 110 and a first wrench 125 connected to one end of the trigger body 124. The handle body 110 has a clearance groove 113, and one end of the first wrench 125 extends beyond the handle body 110 through the clearance groove 113. A second wrench 114 extending beyond the handle body 110 is provided at the end of the handle body 110, with the first wrench 125 located in front of the second wrench 114.

[0056] See Figures 7-8 When the operator manually pulls the first trigger 120, the entire transmission system is activated. The sliding member 130 moves along the designed motion track 112, thereby driving the actuation cable in the actuation cable channel 300. When the movement reaches its end point, the first trigger 120 and the second trigger 141 lock together, facilitating the end effector to complete the corresponding mechanical action. When the handle needs to be unlocked, the operator manually pulls the return lever 144, causing the second trigger 141 to rotate clockwise. The second trigger 141 disengages from the first trigger 120, and the first trigger 120, under the action of the first elastic member 150, drives the sliding member 130 back along the motion track 112, thus achieving the unlocking function.

[0057] Therefore, this application is an endoscopic suture handle that can be operated by interchangeable left and right hands. It not only brings great convenience to doctors during surgery, but also improves and simplifies the setting of the instrument channel 210 and the handle locking mechanism, thereby optimizing the entire handle.

[0058] This application uses a mechanical structure to change the previous method of operating endoscopic staplers with only one hand. This application aims to allow for left- or right-hand switching of operation based on the surgeon's operating habits.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
