Abstract

The utility model discloses a puncture outfit, the puncture outfit includes the sleeve pipe, sheathed tube one end is equipped with the pjncture needle, the inside of pjncture needle is the inside and outside hollow structure of intercommunication cover intraductal portion, be equipped with the suture needle in the pjncture needle, the suture needle with set up to lead in the sleeve pipe and act as go-between and be connected, the end that leads to act as go-between stretches out outside the sleeve pipe. The puncture outfit can be used for dragging the lung, and is convenient for lung operation of patients with lung diseases, thereby avoiding opening a larger incision on the skin and reducing the pain of the patients. The puncture outfit has simple structure, convenient operation and small operation wound, thereby being suitable for the general application of lung operation.

Description

Puncture outfit

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a puncture outfit.

Background

When performing lung surgery on a person with lung disease, the gas inside the alveoli needs to be removed first, and the lungs collapse at this time, and in order to facilitate the surgery, the lungs need to be pulled up to expose the internal organs. At present, the lung is pulled by forceps, so that an incision on the skin is large, and the difficulty and the wound of the operation are increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a puncture outfit which is convenient to operate and greatly reduces the trauma of the operation.

In order to achieve the above object, the present invention provides the following technical solutions:

the puncture outfit comprises a sleeve, wherein a puncture needle is arranged at one end of the sleeve, the inside of the puncture needle is of a hollow structure for communicating the inside and the outside of the sleeve, a suture needle is arranged in the puncture needle, the suture needle is connected with a traction line arranged in the sleeve, and the tail end of the traction line extends out of the sleeve.

Furthermore, a stop device is arranged between the puncture needle and the sleeve.

Furthermore, the cross sections of the stop devices are larger than those of the puncture needle and the cannula.

Furthermore, a positioning device for fixing the traction line is arranged at the tail end of the traction line.

Preferably, the puncture needle is made of stainless steel.

Preferably, the suture needle is made of stainless steel.

Preferably, the pulling lines are made of nylon yarns or metal wires.

Has the advantages that: the utility model provides a puncture outfit uses this puncture outfit accessible puncture approach to get into the thorax, realizes exposing dragging of lung, conveniently carries out minimal access surgery to the patient that suffers from lung disease to avoid opening great edge of a knife on skin, reduce patient's misery. The puncture outfit has simple structure, convenient operation and small operation wound, thereby being suitable for the general application of lung operation.

Drawings

Fig. 1 is a schematic structural view of the puncture outfit of the present invention.

In the figure: 1. a sleeve; 2. puncturing needle; 3. a suture needle; 4. a pulling wire; 5. a stop device; 6. and a positioning device.

Detailed Description

The present invention is further described below with reference to specific examples, which are only exemplary and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications are intended to be included within the scope of the invention.

A puncture outfit comprises a sleeve 1, wherein a puncture needle 2 is arranged at one end of the sleeve 1, the inside of the puncture needle 2 is a hollow structure for communicating the inside and the outside of the sleeve 1, a suture needle 3 is arranged in the puncture needle 2, the suture needle 3 is connected with a pulling line 4 arranged in the sleeve 1, and the tail end of the pulling line 4 extends out of the sleeve 1.

When the lung operation is performed, the puncture needle 2 firstly penetrates through the skin, the suture needle 3 penetrates through the lung, the suture needle 3 is used for connecting the traction line 4 with the lung, the suture needle 3 is cut off, and the traction line 4 is pulled in vitro, so that the suture needle 3 is driven to pull the lung open for the operation. The puncture outfit is very convenient to operate, and the puncture needle 2 only penetrates through a small hole on the skin, so that minimally invasive surgery can be performed, and the trauma of the surgery is greatly reduced.

A stop device 5 is arranged between the puncture needle 2 and the cannula 1. The stopper 5 serves to stop the cannula 1 when the puncture needle 2 penetrates the skin, thereby preventing the cannula 1 from penetrating into the skin.

The stop means 5 can be a stop step, the cross section of which is greater than the cross section of the puncture needle 2. Further, the cross-section of the stop step is larger than the cross-section of the sleeve 1.

In addition, the end of the pulling wire 4 extending out of the casing 1 is provided with a positioning device 6 to fix the pulling wire 4 at different positions relative to the casing 1. Therefore, when different patients are operated, the traction line 4 can be pulled out in different lengths and fixed according to different requirements.

In the preferred embodiment, the puncture needle 2 and the suture needle 3 are made of stainless steel. Of course, the puncture needle 2 and the suture needle 3 may be made of other materials, respectively, as long as they are harmless to the human body and have a certain penetrating power.

Preferably, the pull lead 4 is made of a nylon yarn. The nylon yarn is soft, easy to bend, has certain strength and is not easy to break when pulled. Of course, the pulling wire 4 may be made of other materials such as metal wire.
