Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of laparoscopic surgery use
Flexible puncture outfit, puncture sheath is flexible, to adapt to different operation instrument disengaging.
Technical solution: to achieve the above object, the technical solution of the utility model is as follows:
A kind of flexible puncture outfit of laparoscopic surgery, including the puncture sheath passed through for stab knife, the puncture sheath
Including sequentially connected puncture portion, bending section and stabilizers, the changeover panel of the stabilizers and puncture outfit connects setting, described to wear
Thorn portion punctures tissue, and the both ends of the bending section are separately connected puncture portion and stabilizers, and the puncture portion passes through bending
Portion is bent relative to stabilizers.
Further, the puncture portion and stabilizers are hard pipe structure, and the bending section is flexible pipe body structure.
Further, the bending section is thin-wall metal pipe.
Further, the bending section is bellows.
Further, the bending section is double-wall corrugated pipe structure, and the bending section includes the corrugated outer of outer layer
The inner core tube in straight tube-like of casing and internal layer, the inner core tube and outer tube fusion form.
Further, the total length of the bending section is no more than the one third for puncturing sheath total length.
It further, further include sealing ring, the sealing ring is co-axially located in stabilizers, and close turn of the sealing ring
The side of removable disk, the sealing ring are elastic material, and the sealing ring includes perforation, and the perforation passes through for stab knife, described
The diameter of perforation is less than the internal diameter of stabilizers.
Further, the perforation is taper hole structure, and the necking of the perforation is towards bending section.
The utility model has the advantages that the utility model puncture portion by bending section relative to stabilizers can circumferential skewing, have song
The operation instrument of rate protrude into puncture sheath in, can make puncture sheath local inclination, thus enable operate instrument smoothly into
Enter abdominal cavity, to be operated on a large scale in abdominal cavity.
Detailed description of the invention
Attached drawing 1 is the overall structure diagram of the utility model；
Attached drawing 2 is the half-section diagram of the puncture sheath of the utility model；
Attached drawing 3 is the pipe structure schematic diagram of the bending section of the utility model；
Attached drawing 4 is the structural schematic diagram under the bending state of the puncture sheath of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in attached drawing 1 and attached drawing 4, a kind of flexible puncture outfit of laparoscopic surgery is worn including what is passed through for stab knife
Sheath of sting pipe 1, the puncture sheath 1 include sequentially connected puncture portion 3, bending section 2 and stabilizers 4, the stabilizers 4 with wear
The changeover panel 5 for piercing device connects setting, and the puncture portion 3 is for puncturing tissue to go deep into abdominal cavity, the both ends of the bending section 2
It is separately connected puncture portion 3 and stabilizers 4, and the puncture portion 3 passes through bending section 2 relative to 4 circumferential skewing of stabilizers；Puncture portion
3 by bending section 2 relative to stabilizers 4 can circumferential skewing, the operation instrument with curvature protrude into puncture sheath 1 in,
It can make to puncture 1 local inclination of sheath, so that operation instrument is enable to can smoothly enter into abdominal cavity, it is a wide range of to be carried out in abdominal cavity
Operation.
The puncture portion 3 and stabilizers 4 are hard pipe structure, and the bending section 2 is flexible pipe body structure, are being punctured
When device is protruded into abdominal cavity, bending section and puncture portion are respectively positioned on intraperitoneal, and the stabilizers 4 of hard are located in tissue, work as operation
When instrument protrudes into, stabilizers 4 can reduce interference of the operation instrument to the tissue of incision site, prevent notch from being expanded.
As shown in attached drawing 2 and attached drawing 3, the bending section 2 is thin-wall metal pipe or bellows, to guarantee that it can occur one
Determine the bending of degree.Preferably, the bending section 2 is the double-wall corrugated pipe structure of polyvinyl chloride material, and bending strength is less than
Thin-wall metal pipe bending strength, the bending section 2 include the corrugated outer tube 11 and internal layer of outer layer in straight tube-like
Inner core tube 10, the inner core tube 10 are formed with the fusion of outer tube 11.By double-layer structure, the curved of bellows bending section can be increased
Qu Qiangdu makes bellows be unlikely to excessively soft, guarantees that bending section has certain support strength, with stable connection puncture portion
3 avoid it from being in and take the state held together and damage other organs while but also the bending in puncture portion 3 is controllable with stabilizers 4.
The total length of the bending section 2 is no more than the one third for puncturing 1 total length of sheath, and puncture portion is relative to stabilization
The bending angle in portion in the state of guaranteeing to reach bending requirement, reduces the length of bending section between 0-90 ° as far as possible
Degree, to guarantee to puncture the intensity of sheath.
It as shown in Fig. 2, further include the sealing ring 6 of cyclic structure, the sealing ring 6 is co-axially located in stabilizers 4, and
For the sealing ring 6 close to the side of changeover panel 5, the sealing ring 4 is elastic material, such as rubber, and the sealing ring 6 includes wearing
Hole 7, the perforation 7 pass through for stab knife, and the diameter of the perforation 7 is less than the internal diameter of stabilizers 4.When stab knife is protruded into from perforation
When puncturing in sheath, the sealing ring by elasticity prevents gas leak in abdominal cavity, protects to the further sealing of sheath 1 is punctured
Demonstrate,prove Intra- abdominal pressure；The perforation 7 is taper hole structure, and the necking of the perforation 7 is towards bending section 2, conducive to penetrating for stab knife, together
When guarantee air-tightness.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
