Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an electric laparoscopic stapler. Background Art

[0002] The laparoscopic stapler is one of the important instruments in medical laparoscopic surgery. It is inserted into the puncture cannula pipe matched on the human body to replace the traditional manual suture, and uses titanium nails to cut off or anastomose tissues. This instrument is easy and quick to operate, greatly shortening the operation time. Laparoscopic staplers can be mainly divided into two types: manual and electric, and the commonly used one is the electric laparoscopic stapler now.

[0003] The staple cartridge assembly of the stapler has various models, and the lengths of the cut and sutured tissues are different. If each model needs to be combined with a stapler control body that matches its stroke and the staple cartridge assembly, then each model requires a stapler control body for cooperation, thus increasing the use cost, and the universality of the stapler body is poor, reducing the applicability of the stapler control component. For this reason, people have designed a stapler that can install different staple cartridge assemblies.

[0004] Furthermore, the length specifications of the staple cartridges corresponding to different staple cartridge assemblies are also different, generally 30mm, 45mm or 60mm and other different length specifications. During the operation, the doctor selects a staple cartridge with a suitable staple height and stroke according to the thickness of the affected tissue and the length of the tissue to be cut and anastomosed.

[0005] In order to facilitate the doctor to select a suitable staple cartridge assembly according to actual needs, the prior art such as the published number CN113729823A discloses an electric stapler with a staple cartridge identification system and a staple cartridge identification method. It installs a magnet on the staple cartridge and an identification module in the gun barrel. At this time, multiple identification modules need to be set up to adapt to the magnets of different length specifications of the staple cartridge assemblies one by one, and finally, it is displayed through a display component such as an indicator light on the main control board of the signal processing module. The electric laparoscopic stapler in this case is found to have the following problems through actual research and use:

[0006] First of all, for the identification module, multiple ones need to be set up. In this case, multiple identification modules need to be arranged inside the laparoscopic stapler with limited size, increasing the difficulty of design and assembly.

[0007] Secondly, in the way of using an indicator light for display, for doctors in a highly tense and busy state of use, there is still a situation of misjudgment. It may be inappropriate to use a staple cartridge because the doctor confuses the staple cartridge length corresponding to the indicator light, thus bringing inconvenience to the surgical operation.

[0008] Therefore, regarding the deficiencies in the actual production and use of the current electric laparoscopic stapler, it is necessary to further optimize its overall structure. Summary of the Invention

Specific embodiments

[0045] In order to make the content of the present utility model easier to be clearly understood, the following further describes the present utility model in detail according to specific embodiments and in conjunction with the accompanying drawings.

[0046] Embodiment 1:

[0047] Please refer to Figures 1 to 10As shown in the figure, this embodiment provides an electric laparoscopic stapler, including: a staple cartridge assembly, and a handle assembly connected to the staple cartridge assembly through a gun barrel 300; wherein, the gun head assembly includes a staple magazine 21 and a sleeve 22, and a staple magazine information storage module is detachably assembled on the staple magazine 21 and the sleeve 22 of the staple cartridge assembly; and a signal recognition and processing module is provided in the handle assembly. The handle assembly includes a handle housing 100 and a receiving cavity provided in the handle housing 100 for accommodating the signal recognition and processing module.

[0048] Next, specifically, first is the staple magazine information storage module:

[0049] The staple magazine information storage module includes: a housing, a clamping portion provided on the housing, and an information storage chip 1. The clamping portion is used to realize the clamping of the housing with the staple magazine 21 and the sleeve 22, so as to fix the housing on the staple magazine 21 and the sleeve 22.

[0050] Generally, the clamping portion can optionally adopt an existing clamping portion, which includes at least two arc-shaped cards 3 with opposite arc openings arranged on one side edge of the housing; at least two arc-shaped cards 3 are adapted to enclose to form a clamping interval for clamping the sleeve 22.

[0051] Furthermore, here, in combination with the attached drawings, an optional situation is given: the clamping portion includes more than four, for example, six arc-shaped cards 3 provided on one side edge of the housing; three of the six arc-shaped cards 3 are on one side, and the other three arc-shaped cards 3 are on the other side.

[0052] Based on the above situation, it should be noted that the sizes of the six arc-shaped cards 3 here can be the same or different. In this case, in an optional implementation manner, the four arc-shaped cards 3 on both sides are distributed in a facing and opposite manner or a facing and offset manner. Among them, the facing and offset distribution structure reduces the use of materials, reduces the weight of the instrument, and is convenient for operation while maintaining the clamping force and stability.

[0053] It should also be noted that in this embodiment, each arc-shaped card 3 is made of an elastic material, so that the arc-shaped card 3 can clamp the top magazine sleeve through the elasticity of the material itself after bending. In the state where the housing of this embodiment is clamped with the staple magazine 21 and the sleeve 22, the staple magazine 21 and the sleeve 22 are axially fixed to prevent rotation, and thus are completely positioned to prevent the cutting knife of the electric stapler from shifting. At the same time, it can effectively prevent accidental triggering before use and can distinguish whether the gun head assembly of the electric stapler has been used.

[0054] Next, it should be noted that regarding the information storage chip 1, it is provided in the housing and is used to store the basic information of the staple magazine 21.

[0055] Based on the above structure, in order to facilitate the fixation of the information storage chip 1 in the housing, the housing of this embodiment is further designed as follows:

[0056] Generally speaking, the housing includes a body portion 11 provided with a clamping portion, an assembly groove 12 provided in the body portion 11 for fitting the information storage chip 1, and a cover plate 13 detachably connected to the body portion 11 and adapted to cover the assembly groove 12. Here, the assembly groove 12 is preferably adapted to the shape of the information storage chip 1. For example, both the information storage chip 1 and the assembly groove 12 are rectangular.

[0057] More specifically, the cover plate 13 and the body portion 11 are connected by a snap structure adapted to be buckled. Here, in combination with the accompanying drawings, an optional implementation case is exemplified. The snap structure adopted in this embodiment includes at least two card slots 42 spaced apart on the body portion 11 and at least two snaps 41 provided on the cover plate 13 and adapted to be inserted into the at least two card slots 42 one by one. Four card slots 42 are provided on the body of this embodiment, and four snaps 41 are designed on the cover plate 13 as described above.

[0058] In addition, on the basis of the above structure, considering that in order to prevent the information storage chip 1 from shaking in the assembly groove 12 of the body portion 11, this embodiment is further designed as follows:

[0059] First, a limiting component is further provided between the body portion 11 and the cover plate 13. In combination with the accompanying drawings, an optional implementation case is exemplified. The limiting component includes a pair of limiting grooves 51 provided on the body portion 11 at a pair of opposite side edges of the assembly groove 12, and a pair of limiting ridges 52 provided on the cover plate 13 and adapted to be embedded in the pair of limiting grooves 51; one of the pair of limiting grooves 51 is perpendicular to the side edge of the body portion 11 where the clamping portion is provided.

[0060] Second, a stop portion 6 for preventing the information storage chip 1 from detaching from the assembly groove 12 is further provided on the body portion 11; the stop portion 6 and the side edge of the body portion 11 where the clamping portion is provided are respectively located on both side ends of the information storage chip 1.

[0061] Based on the above situation, considering that the body portion 11 needs to realize the connection with the arc-shaped card 3, the side edge of the body where the arc-shaped card 3 is provided is convex with respect to the cover plate 13 that is clamped in place with the body portion 11. Therefore, it can form anti-shaking limits for a pair of opposite side ends of the information storage chip 1 with the stop portion 6; and then the limiting component is used to realize the anti-shaking limits for the other pair of opposite side ends of the rectangular information storage chip 1. In this way, the anti-shaking limits for the four side ends of the rectangular information storage chip 1 are achieved.

[0062] Thus, the storage of information of the staple cartridge 21 is achieved by the information storage chip 1 built into the housing that can be directly snap-connected to the staple cartridge 21 and the sleeve 22 of the gun head assembly. In this structure, there is no need to design hanging holes for connecting the storage part on the staple cartridge 21 or the sleeve 22 as in the prior art. And in this structure, the housing that can protect the staple cartridge 21 is directly utilized, which reduces the production cost and does not affect the classified placement of a batch of staple cartridges 21, improving the orderliness of the placement of a batch of staple cartridges 21. The information storage chip 1 here can be a card with a magnetic stripe, an inductive electronic wafer, or an integrated circuit card.

[0063] Next, the signal recognition and processing module will be described:

[0064] Generally speaking, the signal recognition and processing module adopted in this embodiment includes a circuit board 201 provided in the handle assembly, and an identification part 202 provided on the circuit board 201 for identifying the information storage module of the staple cartridge, a processing part connected to the identification part 202 for processing the signal sent by the identification part 202, and a display screen 203 connected to the processing part for outputting the information of the staple cartridge. Among them, the identification part 202 can generate different electrical signals with the information storage modules configured with different staple cartridge assemblies and send them to the processing part. Here, an optional implementation case is given as an example. The identification part 202 adopts an induction coil.

[0065] In this structure, through the display screen 203 provided on the circuit board 201, the information corresponding to the staple cartridge assembly can be intuitively displayed. For example, the length specification of the staple cartridge is directly digitally displayed, avoiding the problem that the doctor makes a mistake in the specification of the staple cartridge assembly and causes the surgical progress to be blocked.

[0066] Based on the above situation, it should be noted that the handle housing 100 is provided with an induction window 101 corresponding to the identification part 202 for inducting the information storage module of the staple cartridge. And the handle housing 100 is provided with a transparent window 102 corresponding to exposing the display screen 203.

[0067] Of course, it should also be noted that for the electric laparoscopic stapler of this embodiment, it further includes a battery pack 400 for power supply and a firing mechanism provided in the handle housing 100 for firing the gun head assembly. The firing mechanism can optionally adopt any mature means in the prior art, such as but not limited to a motor 501, an output gear 502 connected to the motor 501, and a transmission rack 503 connected to the output gear 502. Based on this situation, the circuit board 201 can control the rotation of the motor 501, and corresponding buttons 103 can be designed on the circuit board 201 to control the working state of the motor 501.

[0068] For the above-mentioned button 103, taking an optional implementation as an example, it can be a forward button, a backward button, and a confirmation button; among them, the confirmation button can be used to confirm whether the staple cartridge assembly is in the closed position or the firing position. The forward button is used to control the motor 501 to drive the rack to move forward in the direction of the staple cartridge assembly, and the backward button is used to control the motor 501 to drive the rack to move backward in the direction away from the staple cartridge assembly.

[0069] In summary, for the electric laparoscopic stapler of this embodiment, the specification information of the staple cartridge assembly connected to the gun body can be accurately identified, facilitating the doctor to select the appropriate instrument during the operation.

[0070] Embodiment 2:

[0071] Please refer to Figures 1 to 10 As shown, based on the electric laparoscopic stapler of Embodiment 1, the electric laparoscopic stapler provided in this embodiment further includes an indicator light 105 provided on the circuit board 201 to adapt to staple cartridge assemblies of various different specifications and models; and a light-transmitting window corresponding to the indicator light 105 is provided on the handle housing 100.

[0072] Here, in order to effectively utilize the space on the outer wall of the handle housing 100, a pressing part 104 adapted to the button 103 is provided on the outer wall of the handle housing 100, and the indicator light 105 can be distributed circumferentially around the button 103 to improve the compactness of the structure on the overall circuit board 201. At this time, by setting the pressing part 104 as a light-transmitting body, the light of the indicator light 105 can be directly transmitted through the pressing part 104.

[0073] Based on the above situation, that is, not only can the information corresponding to the staple cartridge assembly be visually displayed through the display screen 203, but also different specifications of staple cartridge assemblies can be distinguished by the lighting of the indicator light 105. Thus, through double insurance, it is ensured that the doctor can select the accurate staple cartridge assembly for the operation.
