Technical Field

The invention belongs to the technical field of medical instruments, and particularly belongs to an abdominal cavity puncture outfit.

Background

The development of minimally invasive surgical therapies has brought about the rapid development of related instruments, and has also enabled endoscopic procedures to be widely performed. Minimally invasive surgical treatment is increasingly used in general surgery, thoracic surgery, urology surgery, gynecology, pediatrics and other operations. The puncture outfit is mainly used for establishing a passage for the instrument to enter and exit in the process of the abdominal cavity minimally invasive surgery. On one hand, the requirement of being capable of meeting the requirements of various endoscopic medical instruments to smoothly enter and exit the abdominal cavity and finish the operation is met; on the one hand, it is desirable to maintain a constant pressure within the abdominal cavity, i.e., pneumoperitoneum.

The air-blocking valves adopted by the existing abdominal cavity puncture outfit are all completely fixed in the puncture outfit, and in the operation process, when the internal tissue stump to be removed is larger, the air-blocking valves block the internal tissue stump, so that great difficulty is caused.

Preferably, the puncture cap is fixedly connected with the puncture cover through a buckle structure, and the buckle structure comprises a buckle groove arranged at an eccentric position on the upper surface of the puncture cover and a buckle hook arranged on the puncture cap.

Preferably, the upper end of the puncture cap is irregularly configured.

Preferably, the number of the buckling grooves is 2, and the eccentric position of the upper surface of the puncture cover is that the positions between the buckling grooves and the buckling grooves are not symmetrical about the circle center of the puncture cover.

Preferably, first many lamellas seal membrane is including sealing washer, elastic seal membrane, reinforcing ring, the many lamellas membrane structure with the interior sleeve pipe lock of second in proper order from outside to inside, the sealing washer is formed with the lock recess with the interior sleeve pipe lock of second.

The invention has the advantages that: 1. the first sealing device is designed into a movable whole, so that when the stub needs to be taken out, the first sealing device can be taken out, the stub can be taken out more easily and conveniently, and the subsequent use of the first sealing device cannot be influenced. 2. The invention simultaneously arranges the first multi-petal sealing film and the second multi-petal sealing film to form the double-layer one-way choke valve, so that when an instrument passes through, the gas leakage generated during the passing process is effectively reduced, and the air tightness can be efficiently kept. 3. Gaps are formed among the rounded corners on the edge of the second multi-flap sealing film, so that the resistance of passing of instruments is reduced, and the positions of the passing instruments can be found easily. 4. The lower downwardly extending of the edge of seal membrane forms seal structure, and seal structure between seal membrane and the seal membrane pastes tightly each other, has effectively increased the laminating area between seal membrane and the seal membrane for the realization that can be better is sealed and is hindered the gas effect. 5. The puncture cap passes through buckle structure and puncture lid fixed connection, buckle structure including set up the buckle groove of covering upper surface eccentric position at the puncture and set up the buckle of covering at the puncture cap and collude the constitution, eccentric structure can effectively prevent the wrong direction of dress, and the puncture cap can only be in the same place with puncture lid lock on a position, when puncture cap rotatory certain angle, will unable and puncture lid lock together. 6. The upper end of the puncture cap is of an irregular structure, the ergonomics after being held by one hand is fully considered, and the puncture cap is designed to be an asymmetrical and irregular puncture cap. The utility model is convenient for the user to hold more comfortably and apply more force more conveniently during the operation. 7. The first multi-valve sealing film sequentially comprises a sealing ring, an elastic sealing film, a reinforcing ring and a multi-valve structure, wherein the sealing ring is buckled with the second inner sleeve from outside to inside, and a buckling groove buckled with the second inner sleeve is formed in the sealing ring. The reinforcing ring can prevent the multi-valve structure from cracking, and simultaneously enables the passing instruments to be wrapped better, so that the air tightness effect is better; the lock recess of sleeve pipe lock in the sealing washer formation and the second can strengthen sealed effect, and the elasticity seal membrane can be so that after the puncture ware was inserted to the apparatus, the operation can produce certain deformation when rocking, follows the apparatus activity, guarantees simultaneously that there is good sealed effect.
