Problems solved by technology

[0004] The disadvantage of self-made abdominal puncture needle or using a large-size neurosurgical suction head to make abdominal puncture needle for abdominal puncture, or steel pipe and Kirschner wire puncture the abdominal cavity is that the puncture damage is large, and it is not available on the market, so it is difficult to popularize and apply
Laparoscopy and insufflation machine assisted lower tube insertion, which has high reliability, but the disadvantage is that two teams are needed, one for drilling and tunneling, and the other for mastering the abdominal cavity

Abstract

The invention provides an abdominal cavity puncture and intubation device, which is suitable for intubation in a pleuroperitoneal cavity and used for in-vivo drainage, for example, guiding the abdominal-cavity end of a shunt used in the ventriculoperitoneal shunt into an abdominal cavity in a ventriculoperitoneal shunt process. The device comprises a puncture needle, a guide thread and a lacerable catheter sheath and also comprises a puncture protector, wherein the puncture protector comprises an inner core, a nut and a spring. The in-vivo puncture and intubation device has the advantages that: the thoracic and abdominal wall is not required to be cut; damage is small; surgery sequelae are few; operation is simple and safe; surgery cost is low; and the like.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a device for puncturing and inserting tubes in the body. Background technique [0002] In the process of treating patients, doctors sometimes need to put tubes in the body, so as to export the fluid in the body or introduce medicines and nutrients. At present, the usual surgical method is to introduce the surgical tube after surgery. For example, ventriculoperitoneal shunt surgery requires incision of the abdominal wall for traditional ventriculoperitoneal shunt surgery; the operation time is long and the damage is large. The risk of abdominal wall hernia; at the same time, the patient needs to stay in bed, and the recovery is slow; left surgical scars in the abdomen. [0003] In recent years, with the deepening of the concept of minimally invasive surgery, it has been reported that a catheter was inserted into the ventricle of the abdominal cavity through abdominal pu...
