Description

Detachable abdominal cavity puncture outfit

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a detachable abdominal cavity puncture outfit.

Background

The puncture outfit is a surgical instrument-puncture guide, generally comprising a puncture outfit, an abdomen puncture outfit, a chest puncture outfit, a disposable sterile laparoscope puncture outfit and a disposable sterile sleeve puncture outfit; a passive medical device; its function is generally to puncture tissue (excluding lumbar vertebrae, blood vessels, ventricles of the brain) and establish a pathway.

A large number of searches show that: chinese utility model patent: application No. (CN 201921609949.6), publication No. (CN 210903280U), the utility model discloses a detachable puncture ware, including outer tube, stopper and puncture rod, the tube head welding is in the one end of outer tube, and the tube head deviates from the terminal surface screw thread of outer tube and installs sealed cap, and the outer wall symmetric welding of tube head has the installation piece, the stopper activity is cup jointed at the outer wall of outer tube, and symmetric welding has the slide bar on the stopper, and slide bar slidable mounting is on the installation piece, and threaded cap is installed to the screw thread on the slide bar, and threaded cap is located between stopper and the tube head, the one end activity in proper order of puncture rod passes sealed cap, tube head and outer tube, and the one end welding that puncture rod exposed the outer tube has the puncture head. The utility model discloses, simple structure, it is convenient to use, is convenient for control the puncture depth of puncture ware under the prerequisite that does not influence disease health, satisfies the user demand of operation.

The ventral end of the ventricle-abdominal cavity shunt tube is placed under the assistance of the single-port laparoscope, so that the problems of large trauma, fussy tube placing process, slow recovery of a patient, more complications, high working strength of medical staff and the like of the traditional open abdominal tube placing are solved. When the ventricles of the brain and the abdominal cavity of the abdominal cavity shunt tube are placed under the assistance of the single-port laparoscope, the working process is that the ventricles of the brain are placed by the brain operation group, the ventricles of the brain and the abdominal cavity shunt tube are submerged under the abdominal skin through the neck and chest of a patient, and then the ventricles of the shunt tube are delivered out of the skin by making a small incision on the abdominal skin; at the moment, the operation is carried out by an abdominal operation group, the puncture is carried out by an abdominal needle through a small incision, then the inflation is carried out to avoid damaging organs such as intestinal canal and the like when the puncture is carried out by using a puncture outfit, then the puncture outfit is penetrated into the abdominal cavity through the original incision, and the connection gas maintains the air pressure of the abdominal cavity; because the existing abdominal cavity puncture outfit is designed with a non-detachable slot, a soft drainage tube is often required to be cut into a slot form as a guide tube, the puncture outfit is pulled out after the puncture outfit is placed in the abdominal cavity puncture outfit, and the guide tube is pulled out after the guide tube is guided into the abdominal cavity end of the shunt tube to the abdominal cavity. In the process, as the lumen of the self-made soft guide tube is small and has large friction with the shunt tube, the difficulty or even failure of tube placement often occurs, the abdominal tube placement is switched off or a puncture hole is added to place the tube, the operation wound is increased, the tube placement process becomes complicated, the operation time is prolonged, the hospitalization cost is increased, the patient is influenced to recover quickly, the risk of complications such as collateral damage, incision liquefaction or infection is increased, and the working strength of medical personnel is increased. Therefore, a detachable abdominal cavity puncture outfit is needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a removable abdominal cavity puncture ware possesses the success rate that ventricles of brain-abdominal cavity shunt tubes abdominal cavity end put into under the increase haplopore peritoneoscope, simplifies the advantage of putting the pipe flow, and it is big to have solved the abdomen of opening and put the pipe wound, and the operating time extension, the cost of being in hospital increases, and the patient is recovered slowly, and the problem of complication risk such as vice damage, incision liquefaction or infection increases, medical personnel working strength increase.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a removable abdominal cavity puncture ware, includes pipe, adapter sleeve and limit baffle, pipe outer wall top fluting and activity cartridge have the puncture rod, puncture rod one end and adapter sleeve one side fixed connection, the adapter sleeve has communicating pipe with puncture rod back to the back fluting of one side and activity cartridge.

Preferably, be equipped with the through-hole in the puncture pole, the through-hole passes through the adapter sleeve and communicates with communicating pipe, but the contact of puncture pole outer wall below and pipe is not fixed connection. Through setting up the through-hole to make this internal gaseous accessible of gas tube puncture the through-hole in the pole and circulate, and puncture the pole activity cartridge in the pipe, thereby can follow the pipe and carry out the activity plug to puncture the pole.

Preferably, pipe one end adopts toper structural design, and pipe other end below is equipped with limit baffle, and limit baffle adopts fan-shaped structural design, and one side that limit baffle deviates from the pipe contacts but not fixed connection with the adapter sleeve. The other end of the catheter is provided with the limiting baffle plate, so that the catheter can be prevented from sliding into the body of a patient after the puncture rod is pulled out.

Preferably, one end of the communicating pipe, which is far away from one end of the connecting sleeve, of the inflation pipe body is communicated and installed, and the pull rod is installed in the inflation pipe body in a sliding mode. Through communicating the installation with the gas tube body communicating pipe to conveniently pour into gas into the through-hole and get into the patient through the gas tube body through communicating pipe.

Preferably, the radius of one side of the connecting sleeve, which is close to the puncture rod, is smaller than the radius of the limiting baffle. Through making the adapter sleeve be less than limit baffle near one side radius of puncture rod to when puncture rod takes out, thereby can press limit baffle and extract puncture rod from the pipe through pulling the adapter sleeve.
