[0001] The utility model belongs to the technical field of cutting staplers, in particular to a laparoscopic linear cutting stapler. Background Art

[0002] The laparoscopic linear cutting stapler is an important instrument used in minimally invasive surgery and is widely used in the cutting and suturing of organs such as the digestive tract and lungs. Its main function is to cut and suture tissues through a mechanical device during the operation, thereby improving the operation efficiency and safety. The use of this instrument greatly reduces the surgical trauma, shortens the operation time, and speeds up the patient's recovery process.

[0003] At the present stage, when using the laparoscopic linear cutting stapler, the staple cartridge is mainly set in advance. However, in actual operation, the installation of the staples in these staple cartridges may be unstable. During use, the staples may fall off due to improper operation or other factors. This will not only affect the smooth progress of the operation, but may also cause unnecessary damage to the patient and increase the surgical risk. Therefore, those skilled in the art have proposed a laparoscopic linear cutting stapler. Summary of the Invention

It is characterized in that: one end of the handle is fixedly connected with a fixed sleeve, one end of the fixed sleeve is rotatably connected with a connecting sleeve, one end of the connecting sleeve is rotatably connected with a fixed clamp, and one end of the connecting sleeve and on one side of the fixed clamp is rotatably connected with a bottom plate; a staple cartridge is movably connected inside the fixed clamp, a sliding groove is opened on the fixed clamp, indicator lights are equidistantly arranged on the fixed clamp, holes are opened on the fixed clamp on one side corresponding to the indicator lights, fixing plates are slidably connected inside the holes, contact rods are fixedly connected inside the fixing plates, pressure sensors are fixedly connected inside the holes, springs are fixedly connected on the outer sides of the contact rods between the pressure sensors and the fixing plates, and indicator boards are fixedly connected to the tops of the contact rods.

[0007] Through the above-mentioned technical means, the fixed splint can be rotated, and the fixed splint can cooperate with the base plate when rotating, so as to complete the clamping and fixing effect, and the contact rod will contact the fixed nail. When in contact with the nail, the pressure sensor will receive a pressure signal, so that the indicator light will light up, and the contact rod will rebound, thereby lifting the indicator plate, so that the indicator plate will bulge, thus avoiding missing nails or inaccurate nail fixing positions.

[0008] The nail bin is provided with extrusion notches inside, and nail positions are equidistantly and staggeredly provided at the bottom of the nail bin, and the nail positions are of a through structure. Bayonet slots are equidistantly provided on both sides of the fixed splint, and two connecting teeth are symmetrically and fixedly connected inside the fixed splint. Extrusion positions are equidistantly and staggeredly provided on the top of the bottom plate, and the extrusion positions are used in conjunction with the nail positions, and a moving block is slidably connected inside the sliding groove; the extrusion position moves to squeeze the nails inside the nail bin, and the nails descend to contact the extrusion position, and the inner walls of the extrusion position are all smooth arc-shaped inner walls, so that the two ends of the nail can be bent to achieve closure, thereby achieving the purpose of suturing.

[0009] A trigger is rotatably connected to one side of the handle, one end of the trigger extends to the inside of the handle, a first tension spring is fixedly connected to the inside of the handle, the first tension spring is connected to the trigger, a movable plate is slidably connected to the inside of the handle, ratchet teeth are equidistantly arranged at the bottom of the movable plate, and a limiting end is fixedly connected to the top of the trigger, and the limiting end is used in conjunction with the ratchet teeth.

[0010] Through the above technical means, by pressing the trigger, the trigger is engaged with the ratchet teeth, thereby driving the movable plate to move, and the trigger will pull the first tension spring during the pressing process, so that the trigger can be reset by pulling the first tension spring.

[0011] The movable plate is fixedly connected with a pull block, which extends to the outside of the handle and is slidably connected to the handle. One end of the movable plate is fixedly connected with a movable rod, which extends to the inside of the fixed sleeve. The pull block can pull the movable plate to a working limit state, and the movable plate is fixed by contacting the limit end through the ratchet. After the movable plate moves to the working position, the movable rod will also move to complete the reset state. A first connection position is set at one end of the movable rod, and an adjustment rod is movably connected to the inside of the connecting sleeve. The outer side of the adjustment rod is rotatably connected to a second connection position, and the second connection position is connected to the first connection position.

[0012] A safety device is provided at the bottom of the fixed sleeve. An adjustment knob is rotatably connected to the outside of the fixed sleeve, which is used to control the rotation angle of the connecting sleeve. A rotating knob is rotatably connected to the adjustment knob, which is used to control the rotation angles of the fixed clamp and the base plate.

[0013] By the above technical means, turning the adjustment knob can control the rotation angle of the connecting sleeve, and turning the rotating knob can control the angles of the fixed clamp and the base plate. The horizontal rotation adjustment of the fixed clamp and the base plate is realized by the rotation of the connecting sleeve, and the vertical angle adjustment of the fixed clamp and the base plate can be controlled by the rotating knob, so that the adjustment can be made according to the suture positions at different locations. A visual end is fixedly connected to the outside of the fixed sleeve. A display screen is integrated on the visual end. A power source is movably connected inside the visual end, and the power source is set as a rechargeable battery.

[0014] By the above technical means, the installation condition of the nails inside the staple cartridge can be observed through the display screen, and the pressure condition of each nail can also be observed. A first connection position is provided at one end of the moving rod. An adjustment rod is movably connected inside the connecting sleeve. A second connection position is rotatably connected to the outside of the adjustment rod, and the second connection position is connected to the first connection position. By moving the first connection position, the second connection position can be driven to move. When the second connection position moves, the working purpose of controlling the angles of the fixed clamp and the base plate can be achieved. A third connection position is provided at one end of the moving rod, and a fourth connection position is provided at the top of the adjustment rod. The third connection position is connected to the fourth connection position, and the fourth connection position is connected to the connecting teeth. By moving the third connection position, the fourth connection position can be controlled to move. During the movement of the fourth connection position, the connecting teeth will be driven to rotate, so as to control the opening and closing of the fixed clamp to realize the suture work. A resilient end is fixedly connected to the handle, and a second tension spring is connected inside the resilient end. The second tension spring is connected to the moving plate.

[0015] By setting the second tension spring, the moving plate can have resilience when reset, which is convenient for the user to operate.

[0016] A controller is integrated inside the visual end. The controller is electrically connected to the pressure sensor, the indicator light and the display screen. The power source is electrically connected to the pressure sensor, the indicator light and the display screen.

[0017] Through the above settings, it can be ensured that all the electrical components of this device have connectivity and power input.

[0018] Among the above components, the key component is that a controller is integrated inside the visible end. By being electrically connected to the pressure sensor, indicator light, and display screen, through the state changes of the indicator light, contact rod, and indicator board, that is, the contact rod forms a closed-loop circuit with the nails in the staple cartridge, the pressure sensor will receive a pressure signal, causing the indicator light to turn on, and the contact rod will rebound, thus pushing up the indicator board, so that the indicator board will protrude. In this way, it can be clearly found which staple positions do not have the indicator board protruding. Before clinically using the stapler and staple cartridge, close the clamp head without activating the push knife action button to detect the condition of the nails in the staple cartridge, which can effectively avoid the occurrence of missed nails or inaccurate nail fixing positions.

[0019] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0020] 1. By setting the contact rod, pressure sensor, and indicator light, when the contact rod contacts the fixed nails, the pressure sensor will receive a pressure signal, causing the indicator light to turn on. The contact rod will rebound and push up the indicator board, making the indicator board protrude, clearly showing the state of the nails. This design can effectively avoid the occurrence of missed nails or inaccurate nail fixing positions, thus avoiding the situation of incorrect nail installation positions or missed nails;

[0021] 2. Pull the moving plate to the working limit state through the pull block, and make the trigger engage with the ratchet teeth by pressing the trigger to drive the moving plate to move. After the moving plate is in the working position, it will be reset by the second tension spring, and the whole process is simple to operate. In addition, through the movement of the first connection position and the third connection position, the user can conveniently adjust the angles and opening / closing of the fixed splint and the bottom plate, so as to achieve the suturing work. The overall design makes the device relatively convenient to operate, simple to use, and suitable for various surgical environments. BRIEF DESCRIPTION OF THE DRAWINGS

The extrusion position 18 moves to extrude the nails in the nail magazine 6, causing the nails to descend and contact the extrusion position 18. The inner wall of the extrusion position 18 is a circular arc smooth inner wall, which can bend both ends of the nails to achieve closure and reach the suturing purpose. When the contact rod 10 contacts the fixing nail, the pressure sensor 11 will receive the pressure signal, so that the indicator light 8 lights up, and the contact rod 10 will rebound, thereby lifting the indicating plate 12. In this way, the indicating plate 12 will protrude, so that the situation of missing nails or inaccurate nail fixing positions can be avoided, thus avoiding the situation of incorrect nail installation position or missing nails.
