Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to an anastomat cartridge base. BACKGROUND

[0002] Endoscopic anastomat is widely used in various clinical fields, including general surgery, hepatobiliary surgery, neurosurgery and other surgical operations, as well as gastroenterology, respiratory medicine and other medical operations. The endoscopic anastomat cartridge base is an important part of the endoscopic anastomat, which is usually used in cooperation with the anastomat main body and the anvil seat. Its main function is to form a bend by contacting the anvil seat through the ejection of titanium nails during the operation, thereby achieving the suture of the wound. However, the existing endoscopic anastomat is prone to nail body loosening when held by medical staff or operated improperly, which leads to deviation during suture of the patient's wound, resulting in poor suture effect. In addition, the anastomat cartridge base needs to be disassembled when filling the cartridge, which is complicated and affects the progress of the operation. CONTENT OF THE UTILITY MODEL

[0003] In order to improve the problem that the conventional anastomat cartridge base is prone to nail body loosening, and the operation is complicated when filling the cartridge, the present application provides an anastomat cartridge base.

[0006] An interaction cavity in communication with the plurality of communication grooves two is arranged in the base body, a synchronization plate for fixing the nail body is movably arranged in the interaction cavity, the end of the synchronization plate away from the interaction cavity is in abutment with the side surface of the contact plate, a nail box is inserted and connected to the bottom of the synchronization plate in the interaction cavity, a release port is arranged on the top of the nail box at the position of the plurality of communication grooves two, a plurality of ejectable anastomosis nails are arranged in the plurality of release ports, and a needle groove is arranged on the side surface of each of the plurality of anastomosis nails.

[0007] Through the above technical scheme, the cartridge is inserted into the interaction cavity to make the anastomosis nails pop out, and the synchronous plate preliminarily fixes the anastomosis nails, and then the contact plate is inserted into the base body to drive the anastomosis nails to move to the surface of the communication groove to abut against the patient's tissue, and the contact plate and the base body form a mutual force to fix the anastomosis nails for the second time, thereby preventing the anastomosis nails from loosening and sliding out.

[0008] Preferably, the base body is provided with a synchronous groove at one end of the broken groove, the synchronous plate is extended and inserted into the synchronous groove at one end, and the contact plate is provided with a pushing block at one side of the synchronous groove.

[0009] Through the above technical scheme, the synchronous groove is provided with a space for the movement of the synchronous plate, and the movement of the contact plate drives the movement of the pushing block, thereby providing power for the movement of the synchronous plate.

[0019] By adopting the technical scheme, when the synchronization plate is aligned with the nail box, the pressure on the retractable plate is cancelled, so that the torsional spring at the bottom of the retractable plate is stretched to push the anastomosis nail into the separation slot from the release port.

[0020] Preferably, the two sides of each of the plurality of communication grooves are fixedly provided with an air pressure port, and the air pressure port is connected to an external air pressure device through an air pipe.

[0021] By adopting the technical scheme, the air pressure port is connected to the air pressure device, so that the ejected air pressure ejects the anastomosis nail, and the ejected air pressure discharges the blood and mucus flowing into the communication groove two outside the device for subsequent cleaning work.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. The nail box is aligned with the synchronization plate to cancel the fixing of the anastomosis nail, so that the anastomosis nail is ejected, and the synchronization plate moves to limit the anastomosis nail to prevent excessive ejection, and then the contact plate is inserted to align the synchronization plate with the contact plate, so that the anastomosis nail is limited and moved again, so that the anastomosis nail abuts against the patient's tissue, each movement of the anastomosis nail is limited, and finally the contact plate is movably connected with the base body, so that the communication groove one and the communication groove two continuously exert lateral pulling force on the anastomosis nail, forming auxiliary fixation, avoiding the anastomosis nail from being loose and deviated during the movement of the anastomosis device and the operation of the anastomosis nail, and ensuring the accuracy of the anastomosis nail suture point;

[0024] 2. The lateral insertion action of the top box and the contact plate is used to complete the multiple fixing and moving actions of the anastomosis nail, and provides power for the release of the anastomosis nail, without the need for excessive operation, which is convenient for personnel to use, thereby speeding up the operation progress.
