Description

Technical Field

[0001] The utility model belongs to the technical field of puncture biopsy, in particular to a puncture biopsy gun capable of synchronous anesthesia. Background Art

[0002] A puncture biopsy needle is a medical device used for puncturing and removing living tissue, aspirating cells, etc. during surgery. The existing puncture biopsy gun includes a sampling needle, a cutting sleeve, a launching device, a vibration generating device and a shell; the sampling needle is in an elongated cylindrical shape, including a puncture blade head, a connecting rod, and a needle body. The puncture blade head and the needle body are coaxially arranged as cylinders with equal diameters. When this puncture biopsy gun is in use, the puncture needle of the biopsy gun needs to pass through a catheter that matches the puncture needle, but the needle tube of the puncture needle is relatively thin, which is not convenient for passing through the catheter that matches the puncture needle. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a puncture biopsy gun capable of synchronous anesthesia, which guides the puncture needle so that the puncture needle can pass through a catheter matched with the puncture needle.

[0005] A puncture biopsy gun capable of synchronous anesthesia comprises a launching gun body and a puncture needle body matched with the launching gun body, an anesthetic filling limiting tube assembly is installed on the outside of the puncture needle body, the anesthetic filling limiting tube assembly comprises a reducing tube, an air bag is fixedly installed on the outside of the reducing tube, an anesthetic liquid filling tube is fixedly installed on the inside of the reducing tube, a cavity is opened inside the anesthetic liquid filling tube, a disinfection cotton layer is glued to the lower side of the inside of the anesthetic liquid filling tube, a sealing layer is glued to the outside of an opening opened in the middle and upper part of the inside of the anesthetic liquid filling tube, and a draw rope is glued to the outer surface of the sealing layer.

[0006] Preferably, the cavity is filled with anesthetic.

[0007] Preferably, the inner diameter of the sterile cotton layer is smaller than the outer diameter of the needle tube of the puncture needle body.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] In the utility model, the arrangement of the reducer, the air bag, the anesthetic liquid filling tube, the cavity, the disinfection cotton layer, the sealing layer and the drawstring can apply the anesthetic liquid on the puncture needle body, which is beneficial to guiding the puncture needle body, and the puncture needle body is easy to pass through the catheter matched with the puncture needle body.

[0010] In the utility model, the arrangement of the launch gun body and the puncture needle body is conducive to the effect of puncture biopsy. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is described in detail below in conjunction with the accompanying drawings. As shown in FIG1 , a puncture biopsy gun capable of synchronous anesthesia comprises a launching gun body 1 and a puncture needle body 2 adapted to the launching gun body 1 , and an anesthetic filling limiting tube assembly 3 is installed outside the puncture needle body 2 .

[0016] In this embodiment, combined with the Figure 2 As shown, the anesthetic filling limit tube assembly 3 includes a reducer 31, an air bag 32 is fixedly installed on the outside of the reducer 31, an anesthetic liquid filling tube 33 is fixedly installed inside the reducer 31, a cavity 34 is opened inside the anesthetic liquid filling tube 33, and the cavity 34 is filled with anesthetic, a disinfection cotton layer 35 is glued to the lower side of the inside of the anesthetic liquid filling tube 33, a sealing layer 36 is glued to the outside of the opening opened in the middle and upper part of the inside of the anesthetic liquid filling tube 33, and a drawstring 37 is glued to the outer surface of the sealing layer 36, and a disinfection cotton layer 35 is glued to the lower side of the inside of the anesthetic liquid filling tube 33. The cotton layer 35 is cylindrical, and the air bag 32 enables the reducer 31 to be squeezed and placed on the upper end of the catheter for the external puncture needle body 2. Before puncture, the user tears off the sealing layer 36 through the pull rope 37. After the anesthetic liquid in the cavity 34 flows out, it is absorbed by the sterilized cotton layer 35. When the puncture needle body 2 passes through the sterilized cotton layer 35, the reducer 31 and the anesthetic liquid filling tube 33 guide the puncture needle body 2, and can apply the anesthetic to the puncture needle body 2, which plays a role of synchronous anesthesia during puncture.

[0017] In this embodiment, specifically, the inner diameter of the sterile cotton layer 35 is smaller than the outer diameter of the needle tube of the puncture needle body 2 .

[0018] In this embodiment, specifically, a connecting pipe 38 is integrally provided on one side of the airbag 32 , and an air valve 39 is installed at the connecting pipe 38 .

[0020] In the utility model, before use, the anesthetic filling limiting tube assembly 3 is installed on the upper end of the external puncture needle body 2 catheter, and the puncture needle body 2 is connected to the launch gun body 1. When the user passes the puncture needle body 2 through the external puncture needle body 2 catheter, the anesthetic filling limiting tube assembly 3 limits the puncture needle body 2 and infiltrates the anesthetic.
