The identification signal receivingwire 113 and theidentification signal transmitter 114 are connected in a manner that the two can be electrically connected all the time in the relative rotation process, so that the reliability of signal transmission is ensured, and the reliability of signal identification is further ensured.

It should be noted that the signal input end of the identificationsignal receiving lead 113 is connected with the sending end of the identification signal for transmitting the identification signal to theidentification signal transmitter 114, and in the following description of an embodiment of the electric endoscopic stapler according to the present embodiment, the sending end of the identification signal is in thecartridge assembly 2, but of course, in other embodiments of the present invention, the sending end of the identification signal may also be disposed in theadaptor 1.

In this embodiment, the specific structure that the identification signal receivingwire 113 and theidentification signal transmitter 114 can always keep electrical connection in the process of relative rotation between the two may be:

theadapter 1 further comprises a rotary electrical connector and a stationary electrical connector (the specific structure of both of which will be described later). The rotary electrical connector is fixed in the receiving cavity of therotary body 112 in such a manner as to follow the rotation of therotary body 112 along the axis of therotary body 112, the identification signal receivingwire 113 is fixed with the rotary electrical connector, i.e., the identification signal receivingwire 113 rotates together with the rotary electrical connector, and the signal output end of the identification signal receivingwire 113 is electrically connected with the signal receiving end of the rotary electrical connector.

More specifically, as one embodiment of the rotating electrical connector and the stationary connector:

In the embodiment, the conductiveelastic members 116 and the conductive rings are respectively disposed on the opposite side surfaces of thefirst circuit board 115 and thesecond circuit board 117, and in order to ensure the stability of the electrical connection between thefirst circuit board 115 and thesecond circuit board 117, a plurality of conductive elastic members 11 are disposed corresponding to one conductive ring, and the plurality of conductiveelastic members 116 are arranged with the axis of the rotatingbody 112 as a center. In addition, the conductiveelastic members 116 of the same circle are connected by a wire, so that the stability of the electrical connection between thefirst circuit board 115 and thesecond circuit board 117 can be prevented from being influenced when one of the conductiveelastic members 116 is in poor contact with the conductive ring. Thefirst circuit board 115 and thesecond circuit board 117 may be in an annular structure disposed oppositely, but may also be in other structures as long as it is able to realize that when the rotary electrical connector rotates, the conductiveelastic member 116 on thefirst circuit board 115 always presses against the conductive ring of thesecond circuit board 117 to always maintain electrical connection.

As an alternative to the above structure, as shown in fig. 5, thesecond circuit board 117 may be a circular plate, and the conductive ring is disposed on the circumferential surface of thesecond circuit board 117. When the rotary electrical connector rotates, thefirst circuit board 115 drives the conductiveelastic member 116 to press against the conductive ring on the circumferential surface of thesecond circuit board 117, and the conductive elastic member is slidably connected to the conductive ring, so as to ensure the electrical connection between thefirst circuit board 115 and thesecond circuit board 117.

The fixed electrical connector further includes a fixedhousing 121, one side of the fixedhousing 121 is fixedly connected to thesecond circuit board 117, the other side of the fixedhousing 121 is fixedly connected to themain housing 111, and therotary housing 120 and the fixedhousing 121 are disposed to facilitate mounting and dismounting of the rotary electrical connector and the fixed electrical connector.

As shown in fig. 7, theadaptor 1 further includes awire housing 119 for housing the identificationsignal receiving wire 113, and thewire housing 119 is disposed in the accommodating cavity of therotating body 112 and is fixedly connected to therotating body 112. Therefore, when therotating body 112 rotates, thewire placing shell 119 is driven to rotate, so that thewire placing shell 119 rotates together with the identificationsignal receiving lead 113, a constraint is provided for the identificationsignal receiving lead 113, especially when the identificationsignal receiving lead 113 is long, the stability of the shape of the identificationsignal receiving lead 113 is ensured, the reliability of signal identification is further improved, and the identificationsignal receiving lead 113 is not worn.

In this embodiment, therotating body 112 includes arod body 1122 and a connectingbody 1121, two ends of the connectingbody 1121 are respectively connected to therod body 1122 and themain body shell 111, and cavities are formed in both the connectingbody 1121 and therod body 1122, the cavities of the connectingbody 1121 and therod body 1122 are communicated to form an accommodating cavity of therotating body 112, wherein thewire housing 119 is disposed in the cavity of therod body 1122, the rotary electrical connector is disposed in the cavity of the connectingbody 1121, and the identificationsignal receiving wire 113 penetrates through the two cavities of therod body 1122 and the connectingbody 1121. As shown in fig. 8, theconnection body 1121 is externally connected to themain body housing 111, and a plurality of grooves are formed on theconnection body 1121, and the grooves are engaged with the fingers of the operator, so that the operator can easily dial the connection body while holding the instrument with one hand.

As an alternative to the above-mentioned connection manner in which theconnection body 1121 is externally connected to themain body housing 111, theconnection body 1121 may be partially internally connected to themain body housing 111, and a separation groove is formed on an annular surface of an end of theconnection body 1121 close to the operator, so as to facilitate the single-finger operation of the operator, but of course, theconnection body 1121 may also be completely internally connected to themain body housing 111, as long as theconnection body 1121 can drive therod body 1122 to rotate. It should be noted that, when theconnection body 1121 is externally connected to themain body housing 111, theconnection body 1121 and therod body 1122 serve as visible housings; when theconnection body 1121 is partially inscribed in themain body housing 111, the exposed portion of theconnection body 1121 and therod body 1122 serve as a visible housing; when theconnection body 1121 is completely inscribed in thebody housing 111, therod body 1122 serves as a visible housing.

Example two

As shown in fig. 8, the present embodiment further provides an electric endoscopic stapler, which includes theadaptor 1, thecartridge assembly 2 and thehandle 3 in the above embodiments.

Therefore, the transmission path of the identification signal sent by the identification signal generating structure is as follows: an identificationsignal receiving conductor 113, anidentification signal transmitter 114, and a controller. In this case, thehandle 3 is separately installed outside theadapter 1, but theadapter 1 and thehandle 3 may be an integral structure.

As shown in fig. 9 to 10, in the present embodiment, the identification signal generating structure is an identificationinformation storing chip 21, and the identificationinformation storing chip 21 is disposed in thecartridge assembly 2. The identificationinformation storage chip 21 stores specification information of thenail bin assembly 2, and the specification information is transmitted by taking an identification signal as a carrier, wherein the specification information comprises length information of the nail bin, nail height information in the nail bin, nail shape information in the nail bin, nail length information in the nail bin and nail anvil information in the nail bin.

In this embodiment, the identificationinformation storage chip 21 is an EEPROM (electrically erasable and programmable read only memory), the EEPROM is disposed on thecircuit board 22 of themagazine assembly 2, the identificationsignal receiving lead 113 is connected to thecircuit board 22 through theelastic connection terminal 118, and the identification information is transmitted to the identificationsignal receiving lead 113 through thecircuit board 22 and theelastic connection terminal 118 and then continuously transmitted backward.

In this embodiment, theadapter 1 further comprises a firingbar 122. In the practical application process, due to the fact that target tissues are different, preset information in the controller is different, wherein the preset information in the controller can be manually input or stored through near field identification, when the preset information in the controller is the same as information in the identificationinformation storage chip 21, the controller controls the firingrod 122 to fire thenail bin assembly 2 according to specification information, and then the controller outputs firing completion information to the prompting device, and the prompting device reminds a user of completing firing, so that secondary firing of the user is avoided. When the specification information is different from the preset information in the controller, the controller controls thetrigger rod 122 not to trigger. The prompting device can be a display, a flashing light or a player, and the like, as long as the prompting function can be realized. The firingbar 122 and the related firing structure are conventional and will not be described herein.
