The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1-6, a preferred embodiment of the present invention provides a endoscopic stapler 100 including an adapter, a cartridge assembly 110 removably mounted to the adapter, and a control system.
The adapter comprises a main body shell 121, a rotary shell 122 rotatably arranged on the main body shell 121, an identification push rod 123 arranged in the rotary shell 122, an identification adapter 124 fixedly arranged in the rotary shell 122, an identification piece 125 movably arranged in the main body shell 121 and abutted with the identification adapter 124, and a photoelectric switch fixedly arranged in the main body shell 121.
One end of the identifying push rod 123 abuts against the tail end 111 of the cartridge module 110, and the other end abuts against the identifying adaptor 124. The identification member 125 is located at an end of the identification adapter 124 remote from the identification push rod 123.
The cartridge module 110 is mounted to the adapter by pushing the identification push rod 123, the identification push rod 123 pushes the identification adapter 124, and the identification adapter 124 pushes the identification member 125.
Cartridge assemblies 110 of different staple lengths have different tail end lengths, and the cartridge assemblies 110 of different staple lengths are mounted to the adapter by different distances that push the identification push rod 123. I.e., by varying the length of trailing end 111 of cartridge assembly 110 for different staple lengths, the distance that identifying push rod 123 is moved after cartridge assembly 110 is mounted to the adapter is controlled.
The identification member 125 is provided with a grating. The photoelectric switch recognizes the grating on the recognizing element 125 and transmits the recognition signal to the control system, which determines the stapling length of the cartridge module 110 based on the recognition signal of the photoelectric switch.
The cartridge assemblies 110 with different stitching lengths have different tail end lengths, so that the distance for pushing the identification push rod 123 to move is different, and the grating of the identification piece 125 is further moved to different positions; the photoelectric switch recognizes the position of the grating and provides a recognition signal to the control system; the control system judges the moving distance of the identification piece 125, namely the moving distance of the identification push rod 123 through the identification signal of the photoelectric switch, so as to judge the tail end length of the nail bin assembly 110, and correspondingly obtain the sewing length of the nail bin assembly 110. The medical staff can confirm whether the installed nail cartridge assembly 110 is correct according to the control system identification result, thereby ensuring the smooth operation.
In this embodiment, endoscopic stapler 100 includes three staple cartridge assemblies 110, a first staple cartridge assembly, a second staple cartridge assembly, and a third staple cartridge assembly, respectively. Preferably, the stapling lengths of the first, second and third cartridge assemblies are sequentially increased. The lengths of the tail ends of the first, second and third staple cartridge assemblies are sequentially increased.
Specifically, the suture length of the first cartridge assembly is 30mm, the suture length of the second cartridge assembly is 45mm, and the suture length of the third cartridge assembly is 60mm.
Further, the adapter includes two opto-electronic switches, a first opto-electronic switch 1261 and a second opto-electronic switch 1262, respectively.
In this embodiment, the first photoelectric switch 1261 and the second photoelectric switch 1262 are arranged along the axial direction of the adapter.
Further, the identifier 125 has three gratings, namely a first grating 1251, a second grating 1253, and a third grating 1255, arranged along the axial direction of the adapter. In this embodiment, the first grating 1251 is located between the second grating 1253 and the third grating 1255. The relative positional relationship of the first grating 1251, the second grating 1253, and the third grating 1255 is shown in fig. 3.
The following describes in detail the relationship of the relative positional changes of the identification member 125 with respect to the first and second photoelectric switches 1261 and 1262.
When the adaptor is not mounting the cartridge assembly 110, neither the first nor the second opto-electronic switch 1261, 1262 can identify the grating, as shown in fig. 3.
When the first cartridge assembly is mounted on the adapter, the identifier 125 moves a small distance relative to the first and second opto-electronic switches 1261, 1262. At this time, the first photoelectric switch 1261 recognizes the first grating 1251, and the second photoelectric switch 1262 cannot recognize the grating, as shown in fig. 4.
When the second cartridge assembly is mounted on the adapter, the identifier 125 moves a longer distance relative to the first and second opto-electronic switches 1261, 1262. At this time, the first photoelectric switch 1261 cannot recognize the grating, and the second photoelectric switch 1262 recognizes the third grating 1255, as shown in fig. 5.
With the third cartridge assembly mounted on the adapter, the identifier 125 moves a longer distance relative to the first and second opto-electronic switches 1261, 1262. The first opto-electronic switch 1261 recognizes the second grating 1253 and the second opto-electronic switch 1262 recognizes the third grating 1255.
In summary, when the cartridge assembly 110 is not mounted on the adapter, or when cartridge assemblies 110 having different stapling lengths are mounted, the grating signals identified by the combination of the first and second opto-electronic switches 1261, 1262 are different. So that the control system can determine whether the adapter has a cartridge assembly 110 installed or the staple length of the installed cartridge assembly 110 based on the raster identification signals transmitted by the first and second opto-electronic switches 1261, 1262.
When the first cartridge assembly is mounted on the adapter, the first photoelectric switch 1261 can only identify the first grating 1251; when the adapter is provided with the third cartridge assembly, the first photoelectric switch 1261 can only identify the second grating 1253; and when the second cartridge assembly and the third cartridge assembly are mounted to the adapter, the second opto-electronic switch 1262 can both identify the third grating 1255. To achieve the above effect, it is necessarily required that the width of the third grating 1255 is larger than that of the first grating 1251. Preferably, the width of the third grating 1255 is equal to the width of the first grating 1251, and the width of the first grating 1251 is equal to the width of the second grating 1253.
Of course, the arrangement of the gratings is not limited to the above-described combination, and another combination of gratings is described in detail below.
In another embodiment, the identification member has two gratings, a fourth grating and a fifth grating, arranged along the axial direction of the adapter;
when the nail bin assembly is not installed on the adapter, the first photoelectric switch and the second photoelectric switch cannot identify the grating. At this time, the fifth grating is located between the first photoelectric switch and the second photoelectric switch, and the fourth grating is located at a side of the first photoelectric switch away from the fifth grating.
When the adapter is provided with the first nail bin assembly, the identification piece moves a small distance relative to the first photoelectric switch and the second photoelectric switch. At this time, the first photoelectric switch cannot recognize the grating, and the second photoelectric switch recognizes the fifth grating.
When the second nail bin assembly is installed on the adapter, the identification piece moves for a long distance relative to the first photoelectric switch and the second photoelectric switch. At this time, the first photoelectric switch recognizes the fourth grating, and the second photoelectric switch recognizes the fifth grating;
when the third nail bin assembly is installed on the adapter, the identification piece moves a longer distance relative to the first photoelectric switch and the second photoelectric switch. At this time, the first photoelectric switch recognizes the fourth grating, and the second photoelectric switch cannot recognize the grating.
In conclusion, the first photoelectric switch can recognize the fourth grating when the second nail bin assembly and the third nail bin assembly are installed on the adapter. When the first nail bin assembly and the second nail bin assembly are installed on the adapter, the second photoelectric switch can recognize the fifth grating. So that the widths of the fourth and fifth gratings are wider. Preferably, the fourth grating and the fifth grating have the same width. More preferably, the fourth and fifth gratings have widths equal to the width of the third grating on the identifier 125.
Note that the arrangement of the first photoelectric switch and the second photoelectric switch is not limited to the axial direction of the adapter, and may be arranged in the axial direction perpendicular to the adapter. The size and the position of the grating are reasonably arranged, so that grating signals identified by the combination of the first photoelectric switch and the second photoelectric switch are different, and a control system can judge whether the adapter is provided with the nail bin assembly or the stitching length of the installed nail bin assembly according to the identifying signals transmitted by the first photoelectric switch and the second photoelectric switch.
Furthermore, the endoscopic stapler is not limited to include only three cartridge assemblies having different stapling lengths, but may include two or more than three cartridge assemblies. Through the reasonable arrangement of the number and the positions of the photoelectric switches and the number and the positions of the gratings, when different nail bin assemblies are installed, the grating identification signals collected by the combination of the photoelectric switches are different, so that a control system can judge whether the nail bin assemblies are installed on the adapter or not or the stitching length of the installed nail bin assemblies according to the identification signals transmitted by the photoelectric switches.
The identification piece 125 is abutted with the identification adapter piece 124, so that the situation that the identification piece 125 is separated from the abutment of the identification adapter piece 124 due to inertia and the like is avoided, and further, the situation that a control system judges errors are caused because the photoelectric switch identifies an error grating signal is avoided.
It should be noted that, the identification member 125 is not fixedly connected to the identification adapter 124, that is, the identification member 125 does not rotate along with the rotation of the identification adapter, so that the photoelectric switch can identify the grating signal.
In this embodiment, an elastic member 127 is disposed between the identification member 125 and the main body housing 121. The elastic member 127 gives the identification member 125 an elastic force directed toward the identification adapter 124, thereby urging the identification member 125 into abutment with the identification adapter 124.
Preferably, the elastic member 127 is a tension spring. The main body case 121 is provided with a first hook 1211 and the identification member 125 is provided with a second hook 1252. Both ends of the elastic member 127 are respectively hung on the first hook 1211 and the second hook 1252, and the elastic member 127 is in a stretched state.
Of course, the elastic member 127 is not limited to a tension spring, and may have other structures such as a compression spring.
In addition, the manner of abutting the identification piece 125 against the identification adapter 124 is not limited to providing an elastic piece between the identification piece 125 and the main body case 121, and other manners of abutting the identification piece 125 against the identification adapter 124 may be adopted.
In this embodiment, the endoscopic stapler 100 further includes a display device disposed on the main body housing 121. The control system judges the suture length of the nail bin assembly according to the identification signal transmitted by the photoelectric switch and transmits the suture length to the display device, so that medical staff can judge the suture length of the installed nail bin assembly quickly and accurately during operation.
Specifically, the display device may be a display screen or a display lamp, or the like.
According to the endoscope anastomat, the identified push rod is pushed to move after the nail bin assembly is mounted on the adapter, the identified push rod pushes the identification adapter to move, and the identification adapter pushes the identification piece to move. The nail bin assemblies with different stitching lengths have different tail end lengths, the distance for pushing the identification push rod to move is different, the grating of the identification piece is further moved to different positions, the photoelectric switch identifies the position of the grating, and an identification signal is provided for the control system. The control system judges the moving distance of the identification piece through the identification signal of the photoelectric switch, namely, the moving distance of the push rod, so as to judge the tail end length of the nail bin assembly, and correspondingly obtain the sewing length of the nail bin assembly. The medical staff can confirm whether the installed nail bin assembly is correct or not according to the identification result of the control system.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
