Embodiment 1

[0030] refer to Figure 1-5 , 7, a high-safety cutting stapler with a blocking mechanism, including a handle main body 1, a guide tube 4 and an anastomotic head 5, the side of the handle main body 1 is fitted with a guide tube 4, and the end of the guide tube 4 is fitted There is an anastomotic head 5, and the bottom edge of the handle body 1 is integrally molded with a fixed handle 2, and the fixed handle 2 is connected with a movable handle 3 at one end of the inner side of the handle body 1, and the disposable sealing tape 6 is a one-way plastic cable tie. The middle part of the surface of the disposable sealing tape 6 is surrounded by a perishable sticker, and the inner cavity of the fixed handle 2 is embedded with an unlocking component 8, and the unlocking component 8 includes a locking column 805 embedded in the cavity of the fixed handle 2, and the locking column 805 The bottom of the locking column 805 is provided with an unlocking head 801, and the bottom of the lock...

Embodiment 2

[0032] refer to figure 1 , 2, 6, 7, a high-safety cutting stapler with a blocking mechanism, including a handle main body 1, a guide tube 4 and an anastomotic head 5, the side of the handle main body 1 is fitted with a guide tube 4, and the end of the guide tube 4 An anastomotic head 5 is embedded, and the bottom edge of the handle body 1 is integrally molded with a fixed handle 2. The fixed handle 2 is connected with a movable handle 3 on one end of the inner side of the handle body 1. The disposable sealing tape 6 adopts a one-way plastic binding wire The middle part of the surface of the disposable sealing tape 6 is surrounded by a perishable sticker, and the inner cavity of the fixed handle 2 is embedded with an unlocking component 8. When used as a disposable product, the unlocking component 8 includes a Locking post 805, the bottom of the locking post 805 is provided with a guide groove 801b, a limit spring 802b is provided between the inner cavity of the guide slot 801...

Embodiment 3

[0034] refer to Figure 5 , a high-safety cutting stapler with a blocking mechanism, when used as a circulatory instrument, when working, the disposable sealing tape 6 and the disposable sealing sheet 704 are first torn off, and then due to the driving force of the torsion spring shaft 705 , so that the middle locking tongue 703 is ejected and rests on the edge of the component cavity 706, and then the user presses the movable handle 3, and the middle locking tongue 703 enters through the tongue guide groove 803, because the one-way buckle 702 squeezes the tongue The curved surface of the guide groove 803 of the tongue, thereby driving the entire locking column 805 to move upward. The elastic force of the spring 807 squeezes the locking column 805 downward, and when the locking column 805 moves downward, the overall position of the locking column 805 is limited by the guide rail 802. After the downward movement, the one-way buckle 702 tilts Insert it into the hasp fixing hole...

Abstract

The invention provides a high-safety cutting stapler with a blocking mechanism, which includes a handle main body, a guide tube and an anastomotic head, the side of the handle main body is fitted with a guide tube, and the end of the guide tube is fitted with an anastomotic The bottom edge of the handle body is integrally molded with a fixed handle, and the fixed handle is pin-connected with a movable handle at one end inside the handle body, and an unlocking component is embedded in the inner cavity of the fixed handle, and the movable handle The inner cavity of the safety component is embedded with a one-way buckle to squeeze the curved surface of the guide groove of the tongue, thereby driving the entire locking column to move upward. The buckle completely penetrates the guide groove of the tongue. Due to the elastic force of the guide spring, the locking column is squeezed downward. When the locking column is moving down, the locking column is fully limited by the guide rail. After moving, the one-way hasp is obliquely inserted into the hasp fixing hole of the locking column to realize complete locking.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to a high-safety cutting stapler with a blocking mechanism. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers , Lung cutting stapler, etc. Endoscopic Cutting Stapler and Disposable Nail Cassette Scope of Application Endoscopic Cutting Stapler and Disposable Nail Cassette are suitable for excision, transection and anastomosis of tissues in abdominal, gynecological, pediatric and thoracic surgeries. It can also be used for resection and transection of liver parenchyma, liver ves...
