Disposable laparoscope soft instrument sheathing canal

Abstract

The invention discloses a disposable laparoscope soft instrument sheathing canal. The sheathing canal comprises a main body, sleeves, sealing caps, an air inlet and outlet module, an incision distraction device, a flat ring and an inner ring, wherein four connecting holes, an air outlet and an inflation hole are evenly formed in the upper surface of the main body; the sleeves are installed in theconnecting holes; the sealing caps are installed at the tops of the sleeves; instrument inlets are formed in the centers of the sealing caps and used for surgical instruments to enter; the air inlet and outlet module is arranged at the top of the main body and used for exhausting air from the human body or conveying the air into the human body; the incision distraction device is vertically connected to the bottom of the main body; the inner ring is arranged in an inner layer of the bottom of the incision distraction device; and the incision distraction device is sleeved with the flat ring andlocated above the inner ring. According to the disposable laparoscope soft instrument sheathing canal, the sleeves, the main body, an inflation valve and the incision distraction device are arranged to be of an integrated structure, so that leakage points are reduced, surgical interruption caused by air leakage during surgery is avoided, and the surgical efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a disposable laparoscopic soft instrument sheath. Background technique [0002] In clinical abdominal minimally invasive surgery, during the operation, laparoscopes, forceps, scissors and other instruments need to be sent into the patient's body for surgical operations. Adequate and easy to operate. [0003] Existing instruments for laparoscopic surgery are mainly composed of a sleeve, a main body, an inflation valve, and an incision spreader, wherein the sleeve, the main body, and the inflation valve are connected as a whole, and the incision spreader is an independent accessory with A fixed ring, when used, the fixed ring needs to be peeled off from the incision spreader first, and the other end of the incision spreader is put into the incision opening of the patient's abdominal cavity, and the outer ring of the incision spreader is turned to open the incision Aft...

AI Technical Summary

Problems solved by technology

The existing instruments for laparoscopic surgery have the following disadvantages: 1. The sleeve is easy to leak air, and the size is fixed. One type of sleeve can only correspond to the size of the surgical instrument; 2. The structure is complex and the operation is cumbersome. Peel off the fixing ring from the incision spreader, and then spread the wound. After finishing the wound spread, you need to put the fixing ring into the incision spreader, and finally put the main body into the incision spreader and use the connecting buckle The operation can only be performed after the piece is firmly locked; 3. The product has multiple joints, and it is easy to leak air during use, which makes the operation unable to proceed normally; 4. The exhaust valve is in the form of a three-way structure, and it needs both hands to operate. convenient
