Placement device for visual ventricle and abdominal cavity shunt tube and application method thereof

Abstract

The invention belongs to the field of implantable medical treatment and particularly relates to an implantable auxiliary instrument for a visual ventricle and abdominal cavity shunt tube. A placementdevice for the visual ventricle and abdominal cavity shunt tube comprises an inner cannula and a sheath, a handle is connected to the rear end of the inner cannula, and a spring is arranged on the inner cannula; a cavity is formed in the inner cannula, a first threaded part is also installed on the inner cannula between the spring and the handle, a blunt end for integrated protection is added, a blunt instrument point can be prevented from scratching the abdominal cavity shunt tube, and unnecessary emergency conditions in the surgery are caused; through arrangement of a micro camera, minimallyinvasive surgery in ventriculo-peritoneal shunt can be observed, the blunt instrument point can also be prevented from scratching the abdominal cavity shunt tube, the unnecessary emergency conditionsin the surgery are caused, the insertion depth can also be observed, and the device helps a user to more accurately and conveniently implement the operation.

Description

technical field [0001] The invention belongs to the field of medical implantation, in particular to the implantation assistance of a ventriculoperitoneal shunt tube. Background technique [0002] For ventriculoperitoneal shunt surgery, when the abdominal end of the ventriculoperitoneal shunt tube is placed in the abdominal cavity, it must be placed through a laparotomy, which is traumatic and can easily lead to complications of laparotomy. In recent years, ventriculoperitoneal shunts have been placed laparoscopically, avoiding the above-mentioned disadvantages such as large trauma, but the ventriculoperitoneal shunts must be inserted into the abdominal cavity with a trocar with a blunt head, and then the proximal end of the ventriculoperitoneal shunt must be inserted subcutaneously through the abdomen to the head and neck. It is connected to the ventricular end of the ventriculoperitoneal shunt tube. During this process, the peritoneal shunt tube is likely to be cut by a blu...

Problems solved by technology

In recent years, ventriculoperitoneal shunts have been placed laparoscopically, avoiding the above-mentioned disadvantages such as large trauma, but the ventriculoperitoneal shunts must be inserted into the abdominal cavity with a trocar with a blunt head, and then the proximal end of the ventriculoperitoneal shunt must be inserted subcutaneously through the abdomen to the head and neck. It is connected to the ventricular end of the ventriculoperitoneal shunt tube. During this process, the peritoneal shunt tube is likely to be cut by a blunt instrument, causing danger to the patient, and the insertion is to enter the gap between the intestine and the intestinal wall. The existing insertion method is Insert in a straight line, if the operation is not good, the tube will be inserted directly into the intestine, causing damage
