Description
Technical Field
The utility model relates to a pneumoperitoneum puncture needle used under a disposable endoscope.
Background
EFR operation plays an important role in treating tumors with deep and firm muscle layers and serosa layers, and gastric wall full-layer excision is needed in operation, so that gastric wall perforation is necessarily generated and postoperative pneumoperitoneum is caused, postoperative pneumoperitoneum symptoms of a patient can be effectively improved through gastrointestinal decompression and abdominal cavity puncture deflation, postoperative complications of the patient and average hospitalization time and cost are reduced, and the EFR operation pneumoperitoneum treatment method is safe and effective.
The pneumoperitoneum after EFR operation is treated by combining the abdominal puncture deflation with gastrointestinal decompression in clinic, and the abdominal puncture deflation is performed at the right lower abdominal Maillard point by using a 14G puncture needle (or a 20ml empty needle). The abdominal cavity puncture deflation can have better clinical effects: firstly, the gastric decompression negative pressure suction can timely remove acidic gastric juice and gas in a gastric cavity, effectively control the pressure in the stomach, lead the suture surface of the EFR to get rid of a low-tension state and a high-acid environment, be beneficial to the healing of wound surface and also help to observe whether secondary bleeding exists or not; secondly, the pressure in the abdominal cavity is reduced through the puncture and deflation in the abdominal cavity, and most patients can quickly relieve the relevant symptoms such as abdominal distension, abdominal pain and the like after the puncture and deflation in the abdominal cavity, and meanwhile, the probability of secondary infection in the abdominal cavity after operation is effectively reduced.
The 20ml empty needle comprises a conventional 20ml syringe and a needle head, and after the needle head is successfully punctured, the 20ml syringe cannot be directly kept in an upright state, and a person is often required to hold the 20ml syringe in the upright state to assist in deflation, so that labor is very consumed; in addition, the needle after puncture has no puncture preventing function, and especially in case of urgent surgery, the puncture is very easy to occur.
Therefore, there is a need to design a disposable endoscopic pneumoperitoneum puncture needle to improve the above-mentioned drawbacks.

In order to achieve the above purpose, the utility model provides a pneumoperitoneum puncture needle used under a disposable endoscope, which comprises a cylinder body with a capacity of 20ml and capable of being filled with sterile water, wherein the lower end of the cylinder body is connected with an outer sleeve, two opposite sides of the surface of the outer sleeve are provided with adhesive sheets with adhesive faces facing downwards, the upper end of the cylinder body is detachably connected with a cover cap, the center of the cover cap is fixedly provided with a needle core, and the needle core sequentially penetrates through the cylinder body and the outer sleeve and stretches out of the outer sleeve.
Preferably, the surface of the cylinder body is provided with scales.
Preferably, wing plates are arranged on two opposite sides of the upper end edge of the cylinder.
Preferably, the upper end of the cylinder body is in threaded connection with the cap.
Preferably, the cap is sleeved in the inner cavity at the upper end of the cylinder body.
Preferably, the outer sleeve is sleeved with a removable protective sleeve below the adhesive patch.
Compared with the prior art, the pneumoperitoneum puncture needle used under the disposable endoscope has the following beneficial effects:
(1) Because the adhesive sheet is arranged at the outer sleeve, the adhesive sheet can be directly adhered to the surface of the abdominal wall after the needle core is punctured, and the barrel can be fixed, so that the barrel is kept in an upright state without manually fixing the barrel, thereby greatly saving time and labor.
(2) The puncture success rate is improved by adopting the core to assist the outer sleeve to puncture the abdominal wall, the core can be taken away, the outer sleeve softer than the hard core is left in the skin, the damage to viscera or abdominal tissues and the possibility of needle puncture in the abdominal cavity caused by the needle left in the deflation process after the successful puncture are reduced.
(3) The rubber plug is adopted, and the needle head is penetrated into the rubber plug after the needle core is pulled out, so that the possibility of needle puncture is reduced.
(4) A protective sleeve is used to protect the outer sleeve from sterility.
(5) The cylinder body and the cap are connected through threads, so that the connection is firm, and the needle core is ensured to successfully puncture the abdominal wall.
The utility model will become more apparent from the following description taken in conjunction with the accompanying drawings which illustrate embodiments of the utility model.

Description of the embodiments
Embodiments of the present utility model will now be described with reference to the drawings, wherein like reference numerals represent like elements throughout.
Referring to fig. 1-3, the pneumoperitoneum puncture needle used under the disposable endoscope comprises a cylinder body 1 with a capacity of 20ml and an inner cavity capable of containing sterile water, and the lower end of the cylinder body 1 is connected with an outer sleeve 11. The two opposite sides of the surface of the outer sleeve 11 are provided with adhesive sheets 12 with downward adhesive faces. Wing plates 13 are arranged on two opposite sides of the upper end edge of the cylinder body 1. The surface of the cylinder body 1 is provided with scales 14.
