Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a stapler with a self-detection function. Background Technology

[0002] Clinical stapled anastomosis is a surgical procedure used to cut and anastomose medically defective tissues. The medical stapler is one of the most common surgical instruments used in clinical tissue cutting and anastomosis surgery. The working principle of the medical stapler is similar to that of a staple. By adjusting the distance between the anvil and the staple cartridge assembly, the tissue is compressed appropriately. When the distance between the staple cartridge assembly and the anvil reaches a safe range for effective suturing, it is fired. Upon firing, the circular blade cuts the medically defective tissue, while the staples in the staple cartridge assembly are compressed into a predetermined shape, completing the cutting and anastomosis of the medically defective tissue.

[0003] However, traditional mechanical staplers require a great deal of effort from the surgeon, and the exertion of force causes the stapler to shake, resulting in instability. Therefore, traditional mechanical staplers have been replaced by active, electric staplers. Active, electric staplers move smoothly, but they also have their instabilities, such as batteries running out of power after prolonged storage, motors failing to move, and electronic components aging. If the surgeon discovers the malfunction of the instrument during the operation, the risk of the surgery increases.

[0004] The main problem with existing technology is that active conventional staplers require purse strings to be filled before firing. If the purse strings are filled and the firing button is pressed, and the battery is dead, the motor cannot run, or there are other abnormalities, the stapler must be replaced, or even the purse strings must be removed. This is time-consuming and laborious for the surgeon, and the risk of the surgery is greatly increased.

[0005] The main reason for the above problems with conventional staplers is that the gun body does not have a self-testing function. That is, before firing the battery, the battery is connected to the gun body to check whether the gun body can operate normally, but this operation should not affect the firing of the staples. Summary of the Invention

[0006] The purpose of this invention is to provide a stapler with a self-testing function, which aims to ensure the stability of the operation and reduce the risk of surgery by performing product testing before operation.

[0007] This invention is achieved through the following technical solution: a stapler with a self-testing function, the main body of which is a stapler, and the firing handle of the stapler is provided with a linkage component, a motor, a rotation unit, a self-testing control module, a switching component, a power module and a trigger; the stapler includes three modes: standby mode, self-testing mode and firing mode.

[0008] The linkage component is slidably installed inside the firing handle, and the firing and resetting of the stapler are achieved by moving forward and backward.

[0009] The motor is installed inside the firing handle, and the rotating unit is sleeved on the output shaft of the motor and driven to rotate by the motor.

[0010] The switching component is mounted on the firing handle;

[0011] The trigger is rotatably connected to the firing handle and controls the opening of the motor in firing mode;

[0012] In standby mode, the motor is disconnected from the power module;

[0013] When the power module supplies power to the motor, the anastomosis device enters the self-test mode from the standby mode: the motor starts to rotate and stops rotating when it reaches the first position. The stopping time or stopping position of the motor is controlled by the self-test control module, and the rotating unit and the linkage component are in a disengaged state in the self-test mode.

[0014] After the motor stops rotating to the first position, the switching component is manipulated to connect the rotating unit with the linkage component, and the connector enters the firing mode from the self-test mode.

[0015] When the anastomosis device is in firing mode, operating the trigger will cause the generator to rotate, which will drive the linkage component to move back and forth to complete the anastomosis and reset. After the reset, the motor will stop rotating.

[0016] Compared with previous technologies, the beneficial effects of the present invention are as follows:

[0017] This invention can automatically detect whether the product can work properly when the device is powered on. After the detection is completed, the device can be switched to a different mode to perform the fitting and then trigger the connection. By detecting whether the instrument is faulty in advance, it can be determined whether the instrument can be used for the procedure, thereby reducing the risk. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings:

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "clockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] like Figure 1-6 As shown: A stapler with self-testing function, the main body of which is a stapler, the firing handle 16 of the stapler is provided with a linkage component, a motor 9, a rotation unit, a self-testing control module, a switching component, a power module and a trigger; the stapler includes three modes: standby mode, self-testing mode and firing mode.

[0032] The linkage component is slidably installed inside the firing handle 16, and the firing and resetting of the stapler are achieved by moving forward and backward.

[0033] The motor 9 is installed inside the firing handle 16, and the rotating unit is sleeved on the output shaft of the motor 9 and driven to rotate by the motor 9.

[0034] The switching component is mounted on the firing handle 16;

[0035] The trigger 13 is rotatably connected to the firing handle 16 and controls the opening of the motor 9 in firing mode;

[0036] In standby mode, the motor is disconnected from the power module;

[0037] When the power module supplies power to the motor 9, the anastomosis device enters the self-test mode from the standby mode: the motor 9 starts to rotate and stops rotating when it reaches the first position. The stopping time or stopping position of the motor 9 is controlled by the self-test control module, and the rotating unit and the linkage component are in a disengaged state in the self-test mode.

[0038] After the motor stops rotating to the first position, the switching component is manipulated to connect the rotating unit with the linkage component, and the connector enters the firing mode from the self-test mode.

[0039] When the anastomosis device is in firing mode, operating the trigger will cause the generator to rotate, which will drive the linkage component to move back and forth to complete the anastomosis and reset. After the reset, the motor 9 will stop rotating.

[0040] The firing handle 16 here includes a lower handle cover 161 and a lower handle cover 162, which are mainly the upper chamber part and the lower handle cover 162 are mainly the lower handle part; the motor of the present invention is mainly distributed in the lower handle part.

[0041] In this invention, the linkage component and the rotating unit are designed to be completely separable or, under specific conditions, in contact. When in contact, the rotating unit can drive the linkage component to move. The rotating unit is driven by a motor 9. The rotating unit can both rotate and move along the axis of the motor 9, for the purpose of separating from and engaging with the linkage component. When the rotating unit and the linkage component are separated, it is in a self-test mode; when they are in contact, it is in a firing mode.

[0042] The self-test control module is set up so that, in self-test mode, after completing the test, it controls the motor to stop moving.

[0043] The rotating unit mentioned above is the rotating wheel 11 structure.

[0044] Based on the different structures or principles of the self-test control module, the following two implementation examples are provided:

[0045] Example 1

[0046] The self-test control module is the first motor control unit, which is installed inside the firing handle (16) and connected to the motor (9). It is used to control the rotating unit in the self-test mode to stop the motor (9) after rotating a certain angle.

[0047] The first motor control unit includes a trigger electrode 172 and a stop electrode 171, which are installed inside the firing handle 16 and do not normally contact each other. The trigger electrode 172, the stop electrode 171, and the motor 9 are electrically connected to the control main board PCBA provided inside the firing handle 16, so that when the trigger electrode 172 and the stop electrode 171 contact each other, the motor 9 stops rotating.

[0048] At this time, the trigger electrode 172 and the stop electrode 171 remain in contact.

[0049] The side wall of the rotating unit is provided with a second switch protrusion 11-6, so that after the rotating unit rotates to a certain angle in self-test mode, the second switch protrusion 11-6 pushes the stop electrode 171 to contact the trigger electrode 172, thereby stopping the motor 9 from rotating.

[0050] Generally, the first motor control unit is installed inside the handle cover 162 of the firing handle 16 and connected to the motor 9. When the power is plugged in, the motor 9 drives the rotating unit to rotate, and when the motor reaches the position of the first motor control unit, the motor 9 stops rotating; the self-test is completed. Since it is in self-test mode at this time, the linkage components do not move.

[0051] Example 2

[0052] The self-test control module is a timing chip electrically connected to motor 9, which causes motor 9 to stop rotating after the rotating unit has rotated for a certain period of time in self-test mode. In other words, the stopping position of the rotating unit is controlled by precisely controlling the running time of motor 9. Generally, the timing chip is installed on the control mainboard PCBA located inside the firing handle 16.

[0053] Both of the above implementation methods aim to control the stopping position of the rotating unit, thereby achieving precise engagement between the rotating unit and the transmission rod 4 when the switching component is activated. The two methods can also be implemented simultaneously, mutually detecting whether the rotating unit has stopped in the correct position.

[0054] The present invention also includes a second motor control unit, which is installed inside the firing handle (16). The second motor control unit and the linkage component are both installed on the trajectory of the rotating unit in firing mode, so that the rotating unit controls the linkage component to move back and forth during the rotation in firing mode to achieve matching and reset, and the motor (9) stops rotating after reset.

[0055] The linkage assembly of the present invention includes a transmission rod 4, a push plate 5, and a push rod 6. The passive end of the transmission rod 4 is hinged to the rear end of the push plate 5, and the front end of the push plate 5 and the rear end of the push rod 6 are connected by a cylindrical pin. The middle part of the transmission rod 4 is rotatably connected to the firing handle 16 through a limiting shaft, and a reset torsion spring is provided at the limiting shaft. The purpose of the reset torsion spring is to keep the push rod 6 in an unfired state by the transmission rod 4 in the detection state.

[0056] The second motor control unit includes a stop plate 8 and a trigger switch 7; the stop plate 8 and the trigger switch 7 are installed inside the firing handle 16, and the stop plate 8 and the trigger switch 7 are not in contact with each other under normal conditions; the stop plate 8 and the trigger switch 7 are electrically connected to the motor 9, so that when the stop plate 8 and the trigger switch 7 are in contact with each other, the motor 9 stops rotating.

[0057] The linkage component is installed inside the firing handle 16 and connected to the push rod 6 to drive the push rod 6 to move back and forth, thereby pushing out the push block of the nail cartridge assembly or retrieving the push block to achieve cutting and fitting.

[0058] The rotating unit is mounted on the motor 9. Driven by the motor 9, the rotating unit always moves in a clockwise circumferential direction, thereby driving the linkage components to move.

[0059] Here, after the self-test is completed, the switching component is manipulated to make the linkage component and the rotating unit collide; the firing mode is activated.

[0060] The second motor control unit is generally installed inside the lower cover 161 of the firing handle 16 and is connected to the motor 9. When the motor 9 operates, after completing the cutting and mating, the rotating unit triggers the second motor control unit, at which point the pusher rod 6 moves backward.

[0061] like Figure 7-9 As shown: The rotating unit is provided with a forward-moving protrusion 11-2, a reverse-moving protrusion 11-3, and a first switch protrusion 11-4;

[0062] The forward-moving protrusion 11-2, the reverse-moving protrusion 11-3, and the first switch protrusion 11-4 are arranged in sequence according to the rotation direction of the rotating unit, so that in the firing mode, the rotating unit sequentially completes the forward-moving protrusion 11-2 pushing the transmission rod 4, the reverse-moving protrusion 11-3 moving the transmission rod 4 to reset, and the first switch protrusion 11-4 pushing the stop plate 8 to contact the trigger switch 7.

[0063] It should be noted that the first switch protrusion 11-4, the forward-moving protrusion 11-2, the reverse-moving protrusion 11-3, and the second switch protrusion 11-6 are offset from each other along the axis of rotation of the rotating wheel 11. Since the forward-moving protrusion 11-2 needs to drive the transmission rod 4 in continuous motion, it occupies a large area. To facilitate the positional distribution of the three protrusions, they are offset from each other along the axis of rotation of the rotating wheel 11. That is, the transmission rod 4 is equivalent to a seesaw, including an active end and a passive end. The initial position of the active end of the transmission rod 4 is located on the trajectory traversed by the forward-moving protrusion 11-2; the final position of the active end of the transmission rod 4 is located on the trajectory traversed by the reverse-moving protrusion 11-3.

[0064] When the driving end of the transmission rod 4 is pushed forward by the forward actuation of the protrusion 11-2, the driven end of the transmission rod 4 will drive the pusher 5 forward, thereby pushing the pusher rod forward and pushing out the suturing and cutting component inside the staple cartridge assembly for suturing and cutting. When the driving end of the transmission rod 4 is pushed backward by the reverse actuation of the protrusion 11-3, the driven end of the transmission rod 4 will drive the pusher 5 backward.

[0065] The forward actuating protrusion 11-2 is a semi-circular protrusion with an increasing distance from the axis of the rotating unit on its outer wall surface, causing the rotating forward actuating protrusion 11-2 to push the active end of the transmission rod 4 away from the axis of the rotating unit; the reverse actuating protrusion 11-3 is an arc-shaped protrusion with a decreasing distance from the axis of the rotating unit on its outer wall surface, causing the rotating reverse actuating protrusion 11-3 to push the active end of the transmission rod 4 closer to the axis of the rotating unit.

[0066] from Figure 7-9 As can be seen, the forward-acting protrusion 11-2 is a semi-circular protrusion with an increasing radius. The distance from its outer surface to the axis of the rotating wheel 11 increases clockwise with respect to the rotating wheel 11. Due to the gradual change in radius, during the process from the initial contact between the forward-acting protrusion 11-2 and the active end of the transmission rod 4 to the end of the contact, the transmission rod 823 will gradually rotate in one direction, realizing the forward movement of the push rod 6.

[0067] The reverse-acting protrusion 11-3 is an arc-shaped protrusion. The distance between its inner side and the axis of the rotating wheel 11 decreases as the rotating wheel 11 rotates clockwise. A protrusion 41 that contacts the reverse-acting protrusion 11-3 is provided on the active end of the transmission rod 4.

[0068] During the rotation of the rotating wheel 11, when the transmission rod 4 stops contacting the forward actuating protrusion 11-2, that is, when the forward actuating protrusion 11-2 pushes the transmission rod 4 away, the transmission rod 4 stops moving forward.

[0069] The rotating wheel 11 continues to rotate, causing the reverse-moving protrusion 11-3 to contact the protrusion 41 of the transmission rod 4, guiding the transmission rod 4 to reset and realizing the retraction of the push rod 41. When the first switch protrusion 11-4 rotates and finally moves the stop plate 8, the stop plate 8 rotates to close the trigger switch 7, thereby turning off the motor.

[0070] The above design ensures that the forward-moving protrusion 11-2 is used to move the linkage component and drive the pusher rod 6 forward, while the reverse-moving protrusion 11-3 is used to move the linkage component and drive the pusher rod 41 backward.

[0071] By setting four different bumps, the rotating wheel 11 can activate different functional modules at different stages as required during rotation.

[0072] A support column 15 is provided above the motor 9. A front positioning column 11-1 is provided on the upper part of the rotating wheel 11, and the front positioning column 11-1 extends into the support column 15. A rear positioning column 11-5 is provided on the lower part of the rotating wheel 11, and the rear positioning column 11-5 is sleeved in the output shaft of the motor 9.

[0073] Here, the front positioning pin 11-1 of the rotating wheel is fitted into the round hole of the support pin 15, and the support pin 15 is limited and fixed inside the handle and cannot move. The motor 9 drives the rotating wheel 11 to rotate, but the rotating wheel 11 can move up and down in the space between the support pin and the motor 9 by the push block 10.

[0074] A spring is placed on the outside of the push block 10 that abuts against the reset handle assembly 14, so that the spring pushes the push block 10 to drive the rotating wheel 11 to disengage from the stop plate 8 and the transmission rod 4 and thus approach the motor 9.

[0075] The switching components include a reset handle assembly 14 and a push block 10;

[0076] The push block 10 is slidably installed inside the firing handle 16; the reset handle assembly 14 is hinged to the firing handle 16, and the reset handle assembly 14 is linked with the push block 10, so that pressing the reset handle assembly 14 will drive the push block 10 to rise upward.

[0077] The bottom of the push block 10 is provided with a fork structure, and the rotating unit is provided with a rotating wheel groove 11-7 that cooperates with the fork structure. The fork structure extends into the rotating wheel groove 11-7, so that the rotating unit can rotate relative to the push block 10, and the lifting of the push block 10 can drive the rotating unit to lift synchronously, realizing the transformation of the rotating unit from self-test mode to firing mode.

[0078] The trigger 13 is rotatably connected to the firing handle 16, and the end of the trigger 13 is provided with a trigger linkage 12; by pressing the trigger 13, the trigger linkage 12 touches the trigger switch provided in the firing handle 16, thereby driving the motor 9.

[0079] In actual use, the standby mode is the factory default state; after pressing the reset handle assembly 14, it is in the firing mode.

[0080] like Figure 10 As shown, the reset handle assembly 14 consists of a handle 14-1 and a self-locking member 14-3, which is positioned on the firing handle 16 by a cylindrical pin 14-2. The handle 14-1 of the reset handle assembly 14 cooperates with the push block 10 to rotate the wheel 11. That is to say, the rotation of the reset handle assembly 14 drives the push block 10 to move, thereby causing the rotating wheel 11 to contact and separate from the transmission rod 4.

[0081] like Figure 3 , 4 As shown: When the battery assembly 1 is placed inside the firing handle 16, the firing handle 16 is immediately powered on, and the motor 9 rotates clockwise, thereby driving the rotating wheel 11 to rotate. However, since the first switch protrusion 11-4, the forward toggle protrusion 11-2, the reverse toggle protrusion 11-3, and the second switch protrusion 11-6 of the rotating wheel 11 are below the stop plate 8 and the transmission rod 4, the rotation of the rotating wheel 11 does not drive the transmission rod to swing, nor does it touch the stop plate 8 to trigger the trigger switch 7.

[0082] After the self-test is completed, the reset handle assembly 14 is pulled, and the reset handle assembly 14 swings clockwise, moving upward against the push block 10 on the side of the rotating wheel 11, thereby driving the push block 10 to move upward, and the push block 10 will drive the rotating wheel 11 to move upward. Furthermore, the self-locking component 14-3 of the reset handle assembly 14 has an elastic arm; when it reaches its highest point, it functions as a self-locking mechanism, preventing the cam 11 from moving up and down within the motor and support column 15 even if the motor 9 drives the rotating wheel 11 to rotate.

[0083] It should be noted that when the self-test stops, the area between the second switch protrusion 11-6 and the first switch protrusion 11-4 of the rotating wheel 11, with an angle between 0 and 120°, falls below the protrusion 41 of the transmission rod 4. This ensures that the rotating wheel 11 can accurately fall into the position passing through the protrusion 41 of the transmission rod 4 when the reset handle assembly 14 moves clockwise, and the first switch protrusion 11-4 is located clockwise above the stop plate 7.

[0084] Finally, pressing the firing handle causes motor 9 to drive the rotating wheel 11, moving the pusher 5 forward to the foremost position at the front of the handle, which is the cutting and staple forming position. Continuing in the same direction, the reverse-moving protrusion 11-3 of the rotating wheel 11 hooks onto the protrusion 41 of the transmission rod 4, causing the transmission rod 4 to swing and retract the cutting assembly. When the first switch protrusion 11-4 of the rotating wheel 11 touches the stop plate 8, it triggers the trigger switch 7, stopping motor 9. At this point, the cutting assembly returns to its initial state. In firing mode, as... Figure 6 As shown, the trigger electrode 172 and the stop electrode 171 are located below the rotating wheel 11, meaning that the rotating wheel 11 will not touch the trigger electrode 172 and the stop electrode 171 when it is running.

[0085] It should also be noted that the present invention further includes an adjusting nut 2, which is installed at the tail end of the firing handle 16. The firing handle 16 is fixed with conventional anti-pin seats, cutting components, etc., via a lead screw 3 and a push pin rod 6. The motor 9 is fixed below the firing handle 16.

[0086] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
