Description

Technical Field

[0001] The present invention relates to the technical field of staplers, and particularly relates to a vocal cord stapler. Background Art

[0002] In the field of modern medicine, as an important surgical instrument, staplers are widely used in anastomosis surgeries of various tissues. Currently, there are a wide variety of staplers on the market, including disposable tubular, linear, and arcuate cutting staplers, etc. They drive the staples pre-placed in the components into the tissues through a mechanical transmission device to achieve permanent stapling of the tissues. However, the existing stapler designs are mainly for tissue anastomosis in parts such as the digestive tract and chest cavity, and their anastomosis methods and sizes are not suitable for vocal cord anastomosis. The vocal cords, as important vocal organs of the human body, have unique anatomical structures and physiological functions. The fine structure and functional requirements of the vocal cords cause many problems for existing staplers in vocal cord anastomosis. For example, the vibration characteristics of the vocal cords require the anastomotic site to remain stable during the healing process, while the staple designs of existing staplers cannot provide sufficient support force, resulting in an unstable anastomotic site. In addition, the fine structure of the vocal cords requires the stapler to minimize damage to surrounding tissues during operation, and the size and operation method of existing staplers may be difficult to meet this requirement. Especially, the vocal cord suture operation takes too long and has high requirements for doctors' operations, which all limit the application of existing staplers in vocal cord surgeries.

[0039] Embodiment 1

[0040] A vocal cord stapler, comprising a first mounting housing, a fixing assembly, a first push rod, an adjusting assembly, a second push rod, a slider push rod, a slider, a stapling assembly, a stapling pressing plate, a stapling pressing plate push rod and a second mounting housing;

[0041] The first push rod and the fixing assembly are installed inside the first mounting housing, and the rear end of the second mounting housing is connected to the front end of the first mounting housing; the adjusting assembly is installed at the rear end of the second mounting housing, the second push rod is installed in the middle, and the stapling assembly and the stapling pressing plate are installed at the front end; the slider push rod and the stapling pressing plate push rod are installed at the front end of the second push rod, and the rear end is connected to the adjusting assembly; the front end of the first push rod is connected to the adjusting assembly, and the middle is connected to the fixing assembly; the slider is installed at the front end of the slider push rod.

[0042] The working principle of this embodiment:

[0043] The first push rod and the second push rod are respectively installed inside the first installation housing and the second installation housing and are connected by an adjustment assembly. The first push rod is horizontally arranged, with its front end connected to the adjustment assembly and its rear end connected to the fixing assembly, and is used to push the second push rod to move. The second push rod is used to push the slider push rod to move and the anastomosis pressing plate push rod to rotate. The slider push rod is installed at the front end of the second push rod, and its front end is connected to the slider. The slider push rod controls the anastomosis assembly through the movement of the slider. The anastomosis assembly and the anastomosis pressing plate are installed at the front end of the second installation housing. The anastomosis assembly is used to place anastomosis nails and nail the anastomosis nails on the vocal cord tissue, and the anastomosis pressing plate presses on the other side of the vocal cord to assist in fixing the anastomosis nails. When the second push rod is pushed forward, the slider push rod pushes the anastomosis nails inside the anastomosis assembly out of the anastomosis assembly and nails them on the vocal cords, and the anastomosis pressing plate push rod rotates the anastomosis pressing plate to achieve the fixation and anastomosis of the vocal cord tissue.

[0044] Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the anastomosis assembly includes a first pressing block, a mounting base, a first ejector rod, a first fixed base, a first spring, anastomosis nails, and a second pressing block;

[0046] The mounting base is installed at the front end of the second installation housing; a first pressing block is arranged at the front end of the mounting base; the first ejector rod is arranged at the lower side of the front end of the first pressing block; the first fixed base is installed below the first ejector rod, and the first spring is installed inside the first fixed base; the upper end of the first ejector rod is connected to the first pressing block, and the lower end is connected to the first spring;

[0047] The second pressing block is arranged at the lower side of the rear end of the first pressing block; the anastomosis nails are arranged below the second pressing block; the upper end of the second pressing block is connected to the first pressing block, and the lower end presses on the top surface of the anastomosis nails.

[0048] The slider is triangular, with its front end being the hypotenuse. When the slider is pushed forward, the hypotenuse of the slider presses down the first pressing block, and the first pressing block presses down the second pressing block and the first ejector rod. The lower end of the second pressing block presses on the top surface of the anastomosis nails, pushing the anastomosis nails out of the mounting base and fixing the anastomosis nails in the vocal cord tissue. When the slider leaves, the elastic action of the first spring jacks up the first ejector rod, and the first ejector rod drives the first pressing block and the second pressing block to rise, driving the second pressing block back to the initial position to achieve the automatic reset function and prepare for pressing the next anastomosis nail.

[0049] The working principle of this embodiment is the same as that of Embodiment 1.

[0050] Embodiment 3

[0051] The difference between this embodiment and Embodiment 2 is that it further includes a staple pusher plate, a second spring, a connecting plate, and a limiting plate; a limiting plate is horizontally arranged on the lower side of the rear end of the installation base; the second spring is installed at the rear end below the limiting plate, and the staple pusher plate is installed at the front end below; one end of the connecting plate is connected to the spring, and the other end is connected to the staple pusher plate.

[0052] A plurality of staples are arranged side by side in front of the staple pusher plate, and the second spring is in a compressed state; when the foremost staple is pushed out of the installation base by the second pressing block and nailed to the vocal cord tissue, the elastic action of the second spring pushes the staple pusher plate forward. The staple pusher plate pushes the next staple under the second pressing block to prepare for the next stapling operation.

[0053] The limiting plate restricts the movement range of the staples to ensure that the staples will not deviate from the target position when released, thereby improving the accuracy and stability of stapling. The second spring provides elastic support. When a staple is used, the elastic action of the spring ensures that the staple pusher plate can accurately push the next staple to the appropriate position, realizing the automatic reset function and ensuring that the staples can be accurately pushed each time.

[0054] The working principle of this embodiment is the same as that of Embodiment 1.

[0055] Embodiment 4

[0056] The difference between this embodiment and Embodiment 3 is that the fixing assembly includes a first connecting block, a pressing rod, a bent rod, a clamping block, a second ejector rod, a second fixing base, a third spring, a straight rod, and a first rotating shaft;

[0057] The first connecting block and the second fixing base are arranged below the first push rod; the pressing rod is installed at the front end of the first connecting block; the third spring is installed in the middle of the second fixing base, and the clamping block is arranged above; the upper end of the second ejector rod is connected to the clamping block, and the lower end is connected to the third spring; the bent rod is arranged on the left side of the second fixing base, one end is connected to the second ejector rod, and the other end is connected to one end of the straight rod; the other end of the straight rod extends below the pressing rod.

[0058] During operation, the rear end of the first connecting block rotates, driving the pressing rod to rotate. The pressing rod rotates and presses downward and forward; a through hole is opened in the middle of the end of the straight rod located below the pressing rod; the pressing rod is arc-shaped, rotates and presses downward and forward, extends into the through hole in the middle of the straight rod, drives the straight rod to move downward, and the straight rod drives the second ejector rod and the clamping block to move downward and press the third spring, so that the clamping block leaves the clamping groove. When the pressing rod releases the straight rod, the third spring pushes the clamping block to reset.

[0059] The working principle of this embodiment is the same as that of Embodiment 1.

[0060] Embodiment 5

[0061] This embodiment is different from Embodiment 4 in that it further includes a movable grip, a fixed grip, and a first rotating shaft; the fixed grip is installed at the rear side of the lower end of the first installation housing, and the movable grip is installed at the front side of the lower end; the first rotating shaft is installed in the middle of the upper end of the movable grip, the middle of the first rotating shaft is connected to the movable grip, and both ends are respectively connected to the first installation housing; the rear end of the first connecting block is connected to the top of the upper end of the movable grip; a torsion spring is installed outside the first rotating shaft.

[0062] During operation, the user holds the fixed grip and then presses the movable grip. The top of the upper end of the movable grip is connected to the rear end of the first connecting block. When the movable grip is pressed, the movable grip rotates and drives the first connecting block installed at the upper end of the movable grip to rotate, and the first connecting block drives it to press downward and forward. When the pressing rod presses downward, it drives the spring pressing rod to move downward, and further drives the second ejector rod and the latch to move downward.

[0063] A card slot is opened in the middle of the first push rod, and the latch usually gets stuck in the card slot. When the latch moves downward, the latch disengages from the card slot, and the first push rod moves forward under the elastic action, pushing the adjustment assembly forward, and further pushing the second push rod forward. When the movable grip is released, the elastic action of the torsion spring makes the movable grip return to the initial position, and at the same time the latch re-enters the card slot of the first push rod to prepare for the next operation.

[0064] The working principle of this embodiment is the same as that of Embodiment 1.

[0065] Embodiment 6

[0066] This embodiment is different from Embodiment 5 in that the anastomosis pressing plate includes a second rotating shaft, a rotating rod, side plates, and a pressing plate body; the second rotating shaft is installed at the front end of the second installation housing; the middle of the rotating shaft is installed with the rotating rod, and both ends respectively extend outward to the outside of the second installation housing and are installed with side plates. The upper end of the side plate is connected to the rotating shaft, and the lower end of the side plate is installed with the pressing plate body; the upper end of the rotating rod is connected to the rotating shaft, and the lower end extends downward.

[0067] The pressing plate body is located below the second installation housing, and the rotating rod is located in front of the anastomosis pressing plate push rod. When the second push rod is pushed forward, the anastomosis pressing plate push rod moves forward, pushing the lower end of the rotating rod to rotate the rotating rod. The rotating rod drives the second rotating shaft to rotate, and the side plates rotate and move upward accordingly, driving the pressing plate body to rotate and press on the vocal cord tissue. Through the rotational movement of the second rotating shaft and the rotating rod, the pressing plate body can press on the vocal cord tissue to ensure the stability and accuracy of the anastomosis process.

[0068] The working principle of this embodiment is the same as that of Embodiment 1.

[0069] Embodiment 7

[0070] The difference between this embodiment and Embodiment 6 is that the adjustment component includes a bearing seat, a chuck sleeve, a fixing pin, a positioning block, an adjustment connecting rod, a rotating sleeve, a longitudinal pushing groove, a baffle, a connecting block, a positioning shaft, a baffle push rod, a positioning block, a baffle sleeve, a third rotating shaft, a clamping plate, a moving groove, a positioning groove, and a transverse pushing groove;

[0071] A baffle is installed at the rear end of the second push rod; a connection hole is opened in the middle of the front end of the first push rod, and moving grooves are opened on both sides of the connection hole; one end of the positioning shaft extends into the connection hole, and the other end is connected to the middle of the baffle; the baffle sleeve is sleeved outside the middle of the first push rod; the baffle push rod is horizontally arranged below the first push rod, one end of the baffle push rod is connected to the baffle sleeve, and the other end is connected to the lower end of the baffle;

[0072] A connecting block is arranged at the front end of the positioning shaft, and a longitudinal pushing groove and a transverse pushing groove are opened on the upper part of the second installation shell. The transverse pushing groove is arranged along the circumferential direction of the shell body of the second installation shell; the rear end of the longitudinal pushing groove is connected to the transverse pushing groove, and the front end extends forward; the adjustment connecting rod is vertically arranged, the upper end of the adjustment connecting rod is located in the transverse pushing groove and is connected to the rotating sleeve. The rotating sleeve is sleeved outside the second installation shell, and the lower end of the adjustment connecting rod is connected to the connecting block;

[0073] Positioning blocks are evenly arranged side by side on the outer side of the front end of the first installation shell, and positioning grooves are correspondingly arranged in the connection hole at the front end of the first push rod. The positioning grooves are located between two adjacent positioning blocks; a positioning block is arranged at the end of one end of the positioning shaft located in the connection hole, and the positioning block is stuck in the card slot to fix the positioning shaft; the width of the moving groove is greater than that of the positioning block. When the positioning shaft rotates, when the positioning block rotates to the position where the moving groove is located, the positioning shaft can move back and forth in the connection hole;

[0074] The fixing pin is vertically arranged, the lower end extends downward and abuts against the outside of the baffle sleeve, and the upper end extends to the outside of the first installation shell and installs a bearing seat; a third rotating shaft is installed in the middle of the bearing seat, and a chuck sleeve is sleeved outside the third rotating shaft; one end of the chuck is connected to the chuck sleeve, and the other end extends outward. A journal is arranged at the front end of the chuck sleeve. The rear end of the second installation shell extends into the front inner side of the first outer installation shell. A through hole is opened at the rear end of the second installation shell, and the fixing pin passes through and abuts against the outside of the chuck sleeve.

[0075] When the operator starts the stapler (such as by operating the handle), the first push rod and the second push rod start to work together. The first push rod moves horizontally, and the connection hole at its front end drives the positioning shaft to move. As the first push rod moves, the positioning shaft slides in the connection hole, and at the same time, the positioning block moves in the moving groove. When the positioning block rotates to the position where the moving groove is located, the positioning shaft can move back and forth along the connection hole, so as to adjust the relative position between the first push rod and the second push rod.

[0076] The connecting block is connected to the lower end of the adjusting connecting rod, and the upper end of the adjusting connecting rod is located in the horizontal pushing groove and connected to the rotating sleeve. When it is necessary to adjust the angle or position of the stapler, the rotating sleeve drives the adjusting connecting rod to move in the horizontal pushing groove and the vertical pushing groove. The structural design of the vertical pushing groove and the horizontal pushing groove allows the adjusting assembly to be flexibly adjusted in multiple directions to meet different surgical requirements.

[0077] During the adjustment process, the positioning block of the positioning shaft moves in the positioning groove to ensure the accuracy of the adjustment. When the adjustment is in place, the positioning block is snapped into the positioning groove again to fix the adjusted position. At the same time, the chuck sleeve and chuck structure on the outside of the third rotating shaft may be used for further positioning or locking to ensure the stability after adjustment.

[0078] The adjusting assembly is connected to the baffle of the second push rod through the positioning shaft, affecting the movement of the second push rod. The movement of the second push rod further affects the actions of the slider push rod and the anastomosis pressing plate push rod, and finally realizes the release of the staples in the anastomosis assembly and the fixation of the vocal cord tissue.

[0079] The working principle of this embodiment is the same as that of Embodiment 1.

[0080] Embodiment 8

[0081] The difference between this embodiment and Embodiment 7 is that it further includes a fixing frame, a third fixing base, a fourth spring, a second dial rod and a second dial block; the third fixing base is installed at the rear end of the first installation housing; one end of the fourth spring is connected to the third fixing base, and the other end is connected to the rear end of the first push rod; the fixing frame is installed outside the fourth spring; one end of the second dial rod is connected to the rear end of the first push rod, and the other end extends to the outside of the first installation housing and is installed with the second dial block.

[0082] The fourth spring is usually in a compressed state, providing forward power for the first push rod. When the chuck leaves the card slot on the first push rod, the fourth spring releases the stored elastic potential energy and pushes the first push rod forward. When the first push rod moves forward, it pushes the second push rod to move forward as well, thereby driving the entire anastomosis assembly to perform the fixation and anastomosis operations on the vocal cord tissue. The second dial block is used to toggle the second dial rod. After the first push rod moves forward, the second dial block is pulled backward to compress the fourth spring, causing the first push rod to reset.

[0083] The working principle of this embodiment is the same as that of Embodiment 1.

[0084] Embodiment 9

[0085] The difference between this embodiment and Embodiment 8 is that the staple includes a staple rod, a bottom plate and a staple head; the bottom plate is horizontally arranged, and staple rods are vertically arranged at both ends of the bottom plate; one end of the staple rod is connected to the bottom plate, and the other end is provided with the staple head.

[0086] The staples are made of a medical absorbable material by the human body. The double staple head design increases the anastomosis area, ensuring that the vocal cord tissue is fixed in a larger area. Each staple head can provide a grasping force in the tissue, thereby increasing the stability of the anastomosis and preventing the staples from loosening or shifting. When the second pressing block presses downwards, the staple rods of the double staple heads are pressed into the vocal cord tissue, and the staple heads of the staple rods act as barbs to achieve tissue fixation and anastomosis, ensuring the reliability and stability of the anastomosis process.

[0087] The working principle of this embodiment is the same as that of Embodiment 1.

[0088] In summary, by setting the adjustment component, the present invention can quickly extend or shorten the overall length of the stapler, ensuring that it can accurately reach the vocal cord part, meet the longer operation distance required for vocal cord anastomosis, thereby significantly shortening the operation time and improving the operation efficiency. Secondly, the optimized push rod linkage mechanism and adjustment component make the operation more convenient and easy to control, reduce the requirements for doctors' operation skills, and make the vocal cord anastomosis operation easier to master. In addition, the synergistic effect of the anastomosis component and the anastomosis pressing plate realizes the precise fixation and anastomosis of the vocal cord tissue through the push rod linkage mechanism, ensuring that the staples can be firmly fixed in the vocal cord tissue, providing sufficient supporting force, and meeting the requirements of the vocal cord vibration characteristics for the stability of the anastomosis site. At the same time, the structural design of the stapler fully considers the fine structure of the vocal cord, and minimizes the damage to the surrounding tissues during the operation process, avoiding tissue damage caused by improper operation.

[0089] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
