Prepuce cutting anastomat nail pushing piece reset limiting structure

Abstract

The invention discloses a prepuce cutting anastomat nail pushing piece reset limiting structure, and belongs to the technical field of medical instruments. The prepuce cutting anastomat nail pushing piece reset limiting structure comprises a nail bin shell, a connecting shell is installed at the left side of the nail bin shell, and ejection pieces are arranged at the two ends of the connecting shell; the outer walls of the ejection pieces are movably connected with a percussion handle, through holes are formed in the left end of the percussion handle, a bell jar is connected to the interior ofthe nail bin shell, and a fixing rod is installed at the left side of the bell jar. According to the reset limiting structure, the two sets of through holes are formed in the left end of the percussion handle, so that the gap between two sets of connecting rods is clamped to one end of the percussion handle; and a threaded rod penetrates through threaded holes and the through holes, so that a grip can be stably fixed to the percussion handle; furthermore, a user can hold the closed grip during percussion, so that strength can be saved; and due to the fact that a dull polish soft cushion is installed at the inner side of the grip, the phenomenon that due to long-time tight holding, the hands ache and slip off can be effectively prevented, the operation safety is improved, and effective guarantee is provided for the safety of a patient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a reset and position-limiting structure of a staple pusher of a circumcision stapler. 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. [0003] The prior art has the following problems: 1. It does not have the function of preventing slippage. After the stapler is fired, it is necessary to continue to hold the firing handle for a period of time. Due to the small size of the instrument, it is easy to cause hand damage when holdi...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following problems: 1. It does not have the function of preventing slippage. After the stapler is fired, it is necessary to continue to hold the firing handle for a period of time. Due to the small size of the instrument, it is easy to cause hand damage when holding the firing handle for a long time. The phenomenon of slipping is easy to cause injury to the patient; 2. There is no indication mechanism for the user to quickly and accurately install the bell cover on the stapler body, so that wrong installation will occur, resulting in incomplete cutting and incomplete anastomosis
