Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a laparoscopic suture device. Background Technology
[0002] Laparoscopic surgery, as a minimally invasive surgical technique, has been widely used in various clinical fields such as general surgery, obstetrics and gynecology, and urology. It involves creating several tiny channels (puncture holes) in the patient's abdomen or chest, and then using a laparoscope and specialized surgical instruments to perform tissue resection and suturing. Among these, the laparoscopic suture device is a key instrument for achieving tissue closure within the body. It replaces traditional manual suturing, aiming to shorten surgical time, improve suture consistency, and reduce postoperative complications.
[0003] Current laparoscopic staplers often face the following technical limitations: First, due to the limited surgical field and changes in tissue tension, the staples after suturing are often arranged in a straight line, which is difficult to adapt to complex organ anatomy. Second, although they have angle adjustment functions, their adjustment range is limited and their structure is complex, making them inconvenient to operate in small body cavity spaces. Summary of the Invention
[0004] The purpose of this invention is to provide a laparoscopic suture device that solves the problems of limited adjustment range and inconvenient operation of existing laparoscopic suture devices by adjusting the settings of the components.
[0005] The technical solution of the present invention is as follows: a laparoscopic suture device, including a fixed handle, an operating rod installed on one side of the fixed handle, a movable cover plate provided on one side of the operating rod, a clamp assembly installed inside the movable cover plate, an adjustment component provided on one side of the fixed handle, the adjustment component including a rotating wheel provided on the top of the fixed handle, a swing rotary switch installed on one side of the fixed handle, an angle controller provided at the bottom of the swing rotary switch, and a cover plate toggle button installed on one side of the fixed handle.
[0006] Preferably, a movable handle is installed on one side of the fixed handle for operating the opening and closing of the clamp assembly.
[0007] Preferably, the swing-rotary switch is used to lock the posture of the laparoscopic suture device to reduce erroneous operation.
[0008] Preferably, a mark is installed on one side of the rotating wheel to facilitate identification of the position of the suture needle.
[0009] Preferably, the clamp assembly has a rounded corner design to reduce sharp edges and make the surface smoother.
[0010] Preferably, the cover plate knob is slidably connected to the fixed handle, and when the cover plate knob is moved to the end of the fixed handle, it can be moved back and forth to achieve the locking function.
[0011] The rotating wheel is used to adjust the rotation angle of the clamp assembly from the outside, so as to accurately adjust the orientation of the suture needle without changing the wrist posture, and adapt to the tissue suturing needs in different directions. The swinging rotary switch is used to lock the posture of the laparoscopic suturer after adjustment.
[0012] The angle controller is used to finely adjust the swing amplitude of the clamp assembly, enabling the instrument to flexibly adapt to the operating angle of different anatomical structures in the abdominal or thoracic cavity, thus expanding the applicability of the suture device.
[0013] The clamp assembly has a rounded corner design. The cover plate knob is slidably connected to the fixed handle. When the cover plate knob is moved to the end of the fixed handle, it can be moved back and forth to achieve the locking function.
[0014] The movable handle works in conjunction with the fixed handle to control the opening and closing of the clamp assembly through gripping and pressing actions, enabling clamping and releasing operations to be completed with one hand.
[0015] The beneficial effects of this invention are as follows: by setting a rotating wheel, a swing-rotation switch, and an angle controller, the clamp assembly can be flexibly adjusted in multiple directions and angles, solving the problems of limited adjustment range and inconvenient operation of existing laparoscopic suture devices, and enabling the instrument to better adapt to complex anatomical morphologies; by setting a cover plate toggle and a movable handle, the convenience of opening, closing, and locking operations is improved; the rounded corner design of the clamp assembly surface reduces sharp edges, improving passability and safety; the marking facilitates quick identification of the suture needle position during surgery, effectively improving suturing accuracy and surgical efficiency.
