Abstract

A disposable stapler with a plurality of vent holes belongs to the field of medical instruments and comprises a nail anvil at the upper part of the stapler, and a nail-storing box which is connected with the lower part of the stapler through a circlip pipe; the top end part of the nail anvil at the upper part of the stapler is provided with 4 to 20 vent holes that pass through a nail anvil cover;5 to 20 vent holes are arranged on the side surface of the nail-storing box at the lower part of the nail anvil; and the vent holes are from 1.5 mm to 2 mm in diameter and are evenly distributed on the top end of the nail anvil and the side surface of the nail-storing box. When the stapler is closed, the pressure in an anastomotic mouth can be vented through the plurality of vent holes towards a pressure cavity; a pipe wall organization is effectively protected, thereby preventing non-necessary congestion and injury of the pipe wall organization. The disposable stapler has good surgery effectand shortens the surgery recovery time of the patients.

Description

With a plurality of disposable use anastomats of leading the hole off

Technical field

This utility model belongs to medical instruments field, is specifically related to the disposable use anastomat of leading the hole off with a plurality of.

Background technology

Before this, I have applied for a utility model patent in November, 2008 to State Intellectual Property Office, exercise question is " band is led the disposable anastomat of one-piece type nail anvil in hole off ", application number is 200820178201.0, the content that it is expressed is: be provided with 1-3 on the nail anvil top and lead the hole off, storage nail box side is provided with 2-4 and leads the hole off, in the medical treatment feedback, find the set quantity of leading the hole off and structure be set all desirable not enough, because in the process of doctor's operation, because nail anvil is pulled to storage nail box when tightening up the tube wall tissue at clamping two ends, speed is very fast, this moment, tube wall tissue was the pressure chamber that packs tightly two ends respectively, moment can be caused too high anastomotic stoma internal pressure, leads the hole off and is not enough to lead off fully rapidly the interior pressure of anastomotic stoma very little, and the tissue that at this moment is sewn can cause hyperemia, make patient's postoperative be sewn the organized renewing time lengthening, will increase patient's financial burden.In order to improve this situation, the applicant has researched and developed new design again, and has carried out experimentation.Facilitated declaring of this patent.

Summary of the invention

This utility model technical issues that need to address are to design a kind of a plurality of holes of leading off that have at above-mentioned weak point, the disposable anastomat of leading off in the different structure position simultaneously, in order to reach the purpose of this utility model, on the nail anvil top on anastomat top and Chu Ding box side, be added with a plurality of holes of leading off simultaneously, the purpose of this utility model takes following scheme to realize, a kind of with a plurality of disposable use anastomats of leading the hole off, comprise the nail anvil that is positioned at anastomat top, follow closely box through the storage that the jump ring pipe is connected with the bottom, it is characterized in that, the nail anvil head portion on described anastomat top, be provided with 4-20 the hole of leading off through the nail anvil lid, on the storage nail box side of nail anvil bottom, be provided with 5-20 and lead the hole off, describedly lead bore dia off between 2 millimeters of ￠ 1.5-￠, and be uniformly distributed on nail anvil top and the Chu Ding box side.The beneficial effects of the utility model are; when anastomat is closed; pressure in anastomotic stoma A and the anastomotic stoma B can be led the hole off and leads off to pressure chamber A and pressure chamber B by a plurality of; make anastomotic stoma A and pressure chamber A; instantaneous pressure is identical between anastomotic stoma B and the pressure chamber B, and A of tube wall tissue and the B of tube wall tissue are effectively protected, and has avoided the unnecessary hyperemia damage of tube wall tissue; good operation effect has shortened post-operative recovery time of patient.

Among the figure: 1. nail anvil covers, 2. nail anvil top, 3. nail anvil, 4: jump ring pipe, 5. storage nail box, 6. storage nail box side, 7-1. lead the hole off, 7-2. leads the hole off, 8. connects aluminum pipe, 9. handle assembly, the 10. A of tube wall tissue, 11. anastomotic stoma A, 12. anastomotic stoma B, 13. B of tube wall tissue, 14. pressure chamber B, 15. pressure chamber A, 16. anastomosis staple shaping grooves.

The specific embodiment

Has nail anvil lid 1 with reference to accompanying drawing 1 with a plurality of disposable use anastomats of leading the hole off, nail anvil 3, be connected with bottom Chu Ding box 5 by jump ring pipe 4, be respectively equipped with on nail anvil top 2 and the Chu Ding box side 6 and lead hole 7-2 off and lead hole 7-1 off, connect aluminum pipe 8 fronts and connecting storage nail box 5, the back is connecting handle assembly 9.

With a plurality of identical part enlarged drawings in disposable use anastomat tops of leading the hole off, the top nail anvil 3 that can clearly find out anastomat is by the annexation of jump ring pipe 4 with the storage nail box 5 of anastomat bottom with reference to accompanying drawing 2.

Structure chart when with a plurality of disposable use anastomat tops of leading the hole off the A of tube wall tissue and B being coincide with reference to accompanying drawing 3, concrete mentality of designing is: be added with 5-20 simultaneously and lead hole 7-1 off on storage nail box side 6, be provided with 4-20 and lead hole 7-2. off on nail anvil top 2

Face upward diagrammatic sketch with reference to accompanying drawing 4 nail anvils: represented to lead off hole 7-2 in the layout on nail anvil top 2 and the arrangement states of anastomosis staple shaping groove 16.

Claims

1. one kind with a plurality of disposable use anastomats of leading the hole off, comprise the nail anvil that is positioned at anastomat top, follow closely box through the storage that the jump ring pipe is connected with the bottom, it is characterized in that, the nail anvil head portion on described anastomat top is provided with 4-20 the hole of leading off through the nail anvil lid, on the storage of nail anvil bottom nail box side, be provided with 5-20 and lead the hole off, describedly lead bore dia off between 2 millimeters of ￠ 1.5-￠, and be uniformly distributed on nail anvil top and the Chu Ding box side.
