Description

Splittable abdominal cavity puncture outfit with connecting structure

Technical Field

The utility model belongs to the technical field of medical instruments, is mainly used for minimally invasive surgery to puncture human tissues or organs so as to carry out operations such as pipe burying and the like, and particularly relates to a splittable abdominal cavity puncture outfit with a connecting structure.

Background

Ventricle-abdominal cavity shunt is a common operation of hydrocephalus in neurosurgery, but the shunt device implantation process is an important cause for inducing infection, and particularly, the abdominal cavity end implantation is very important. The traditional method is to make an operation incision of about 5cm on the abdomen, open the abdomen layer by layer until the abdominal cavity, place the abdominal cavity end of the shunt tube under direct vision, and close the abdomen layer by layer. This procedure is long in operation time (about 1 hour), traumatic and difficult to operate, especially for obese patients. Wound bleeding, omentum majus and intestinal canal injury or tube placement failure are easily caused in the operation process, and due to large trauma, postoperative complications such as infection, shunt tube blockage caused by omentum majus wrapping, intestinal adhesion, abdominal wall hernia and the like easily occur.

With the development of scientific technology, the concept of minimally invasive surgery has been advanced to various fields of surgical operations, and monitoring systems are not limited to endoscopes, but rather adopt interventional methods such as spinal surgery and orthopaedics. There are other ways, such as microsurgery, which is widely used in hand surgery, etc. Minimally invasive surgery has the advantages that small trauma, light pain and quick recovery are the dream of every patient needing surgery, and the dream is realized by the minimally invasive surgery.

The current common minimally invasive surgery is laparoscopic surgery, wherein an abdominal incision of a patient is firstly made, then a puncture outfit is used for puncturing the abdomen to enter the abdominal cavity, and the puncture outfit establishes an access and operation channel of instruments such as an endoscope, an electrocoagulation scissors and the like. After the operation is finished, the instrument and the puncture outfit are taken out, and the incision is sutured. Such penetrators are used only to provide access for instruments during surgery and are not available for procedures requiring indwelling in a patient. For example, in the operation of pipe burying, the abdominal wall needs to be punctured, the pipeline is implanted into a certain position of a human body, and then the puncture device is taken out without affecting the position of the pipeline, so that the pipe burying is completed.

Although a technical solution to the problems of the prior art is provided in the chinese patent application (application No. 201721813978.5) which discloses an arc-shaped splittable abdominal cavity puncture outfit for a ventriculo-abdominal cavity shunt operation, the following problems still exist: because the puncture cone and the splittable cannula are separated independently, the puncture cone and the splittable cannula are easy to separate in the puncture process, certain difficulty is brought to the operation, and the possibility of puncture failure or complication is increased.
