Configuration applied to biopsy device provided with reusable trigger used for disposable needle

Abstract

The invention provides configuration applied to a biopsy device provided with a reusable trigger used for a disposable needle. The configuration adopts a device used for histology biopsy, and is characterized by being a medical apparatus; the device is composed of a group of disposable needles of 'whole-core'type and the reusable trigger used for soft tissue biopsy, and the needles are designed and developed to be especially used for the trigger, and are not used in other devices; the biopsy devices in the prior art have the inconvenience that during the biopsy surgery process, a user feels uncomfortable and has difficulty in performing processing; for most existing types, the user performs movement twice so that the device is made ready for triggering; after a tissue sample is collected,first-time setting for removal of the sample is needed, second-time setting for placing the tissue sample at the correct position is carried out, and then collecting is carried out; another inconvenience is that the number of the tissue sample extracted from the organ can not enable people to make definite diagnosis satisfactorily under many cases; in order to overcome the inconvenience in the prior art, the device is developed, due to the operating principle, the 'whole-core'(whole sleeve)type can be collected, the needles are moved by front carriers (21) and rear carriers (22), an inner sleeve (7a) and an outer sleeve (6a) are conveyed, rotation motion is provided, and a needle core (9a) is kept still; the carriers are pulled and moved by springs (41) arranged at the front of a structure box (11); the trigger also provides a mechanism, the forward adjustment is realized, the processing is easy, and the needles of the same type can be used for collecting samples of two specifications.

Description

technical field [0001] The object of this patent right is to provide a practical and innovative new device comprising a reusable trigger for a disposable needle of the "full core" type for soft tissue biopsy, the needle is designed Developed specifically for such triggers, it is not possible to use them in other devices; this device belongs to the field of medical devices dedicated to the extraction of tissue (human or animal) samples for histological analysis; the present invention provides novelty for such devices Unique, innovative structure and practical configuration. [0002] Therefore, in the title patent request, we have an extremely innovative device, which has been specially designed and developed to achieve greater practicality and efficiency in use, bringing great advantages to users. Simplification of the production process concept is also an advantage. [0003] The purpose of this request is also to provide a new device for soft tissue biopsy, which has a low i...

Problems solved by technology

[0009] One of the inconveniences of existing biopsy devices is that the user is uncomfortable and difficult to handle during the biopsy procedure; moreover, in most models, the user needs to make two movements to prepare the device for triggering

[0010] Another inconvenience is that after the tissue sample is collected, it needs to be prepared to first remove it and then place it in the correct position for collection, and in some procedures, multiple collections are required, causing great discomfort to the user

[0011] Another inconvenience is related to the number of tissue samples taken from the organ, which in many cases cannot be satisfactorily biopsied and confirmed

[0012] Therefore, the arrangement claimed herein seeks to solve these inconvenient problems existing in the prior art
