The embodiment of the utility model first aspect provides a kind of puncture cap, as depicted in figs. 1 and 2, including upper cover 1 and more
Layer gasket, upper cover 1 have the receiving channel 11 for accommodating multilayer gasket, and multilayer gasket is prolonged along receiving channel 11
It stretches direction to set gradually, forms multiple independent sealed passages 2 between multilayer gasket, sealed passage 2 is worn for surgical instrument
It crosses.
The utility model first aspect embodiment provide puncture cap in multilayer gasket along receiving channel extension side
Multiple independent sealed passages are formd to setting gradually.Before assembly, each layer gasket can be processed respectively, then
Multilayer gasket is set gradually along the extending direction of receiving channel, compared with the existing technology for, the utility model
The puncture cap structure of offer is simple, does not need that cap shell body will be punctured and each sealed bladder is integrally formed, effectively reduce puncture
The difficulty of processing of cap.
It should be noted that in the course of surgery, each sealed passage 2 is used for across a surgical instrument, surgical device
Tool may include endoscope, electric coagulation knife, surgical clamp, etc..
Multiple independent sealed passages 2 such as two, three, four can be formed between multilayer gasket.At at least one
In embodiment, as shown in Figure 1, in order to enable above-mentioned puncture cap can by suitable surgical instrument, and avoid operation wound
It is excessive, at least one embodiment, as shown in Figure 1, three independent sealed passages 2 can be formed between multilayer gasket.
In some embodiments, as shown in Fig. 2, in order to reduce the interference of surgical instrument operation in surgical procedure, Duo Gemi
The extending direction in envelope channel 2 is parallel to each other.It, can be along each self-sealing after each surgical instrument is by respective sealed passage 2
The extending direction in channel 2 enters human abdominal cavity, and each surgical instrument is avoided to hit after through respective sealed passage, side
Just the operation of doctor.
On the basis of the above embodiments, as shown in Fig. 2, the extending direction of each sealed passage 2 be each perpendicular to it is each
Plane locating for layer gasket, enabling doctor, each surgical instrument more accurately reaches lesion in use.
In some embodiments, as shown in figure 3, multilayer gasket includes bottom gasket 3, middle layer gasket 4 and top layer
Tabletting 5, top layer tabletting 5 is for compressing bottom gasket 3 and middle layer gasket 4.Top layer tabletting 5 compresses bottom gasket 3 in
Layer gasket 4 can guarantee that each sealed passage 2 has independent leakproofness, after mounting, bottom gasket 3 and middle layer sealing
Pad 4 and upper cover 1 are interference fitted, and gas or liquid in abdominal cavity is avoided to reveal from the gap between three.
In some embodiments, as shown in Fig. 2, leakproofness in order to ensure each sealed passage, each sealing are logical
Road 2 includes: the one-way sealing sealing of hole 21 passed through on bottom gasket 3 for surgical instrument, is equipped in one-way sealing sealing of hole 21
