Abstract
A kind of expansion type fixation puncture outfit, including puncture cannula and the puncturing lever being threaded through in puncture cannula, puncture cannula includes hard sleeve body, the outer circumferential of hard sleeve body is arranged there are one the soft overlay film body made of flexible material, the both ends of the soft overlay film body are sealed with hard sleeve body respectively, there are one flow-guiding channels for setting between hard sleeve body and soft overlay film body, flow-guiding channel is communicated with soft overlay film body inner space, one end of flow-guiding channel is connect with check valve, and the rear part is in coniform after soft overlay film body gassy or liquid.After hard sleeve body is placed in stomach wall puncture together with soft overlay film body, to the inflation of soft overlay film body or filling liquid, soft overlay film body expansion generates pressure to puncture, hard sleeve body is fixed, and puncture is sealed.The rear part is in coniform after soft overlay film body expansion, under intra-abdominal pressure, forms conical surface seal with stomach wall puncture, hard sleeve body fixes relatively reliable, better tightness.
Description
Technical field:
The utility model is related to mankind life article more particularly to medical instrument, especially a kind of expansion type, which is fixed, to be punctured
Device.
Background technology:
Puncture outfit is common Minimally Invasive Surgery instrument, for piercing through stomach wall and being provided into body cavity for other surgical instruments
The surgical instrument in channel.In the prior art, puncture outfit is single hole straight tube structure, and swing, serious meeting are also easy to produce during use
Deviate from from human body, such as often puncture (10mm or 12mm) takes out gall-bladder under xiphoid-process, but majority need to expand puncture it is suitable
Gall-bladder takes out, and waits after taking out gall-bladder, this puncture being extended be placed in again after puncture outfit will gas leakage, subsequent abdominal cavity punching
Wash, the operations such as detecting can be very inconvenient, or such as in the operation of preperitoneal space, the angle of puncture outfit and stomach wall 30 degree with
It is interior, it is not fixed easily, is not easy to ensure air-tightness, often influences operation progress because puncture outfit slips and gas leakage in surgical procedure,
The wound for having aggravated operation patients has delayed the rehabilitation of patient.
Invention content：
The purpose of this utility model is to provide a kind of expansion types to fix puncture outfit, and this expansion type, which is fixed, to be punctured
The technical issues of puncture outfit that device will solve single hole straight tube structure in the prior art easy tos produce swing, even abjection, gas leakage.
This expansion type of the utility model fixes puncture outfit, including puncture cannula and the puncture that is threaded through in puncture cannula
Bar, the puncture cannula include tubular hard sleeve body, wherein are arranged in the outer circumferential of the hard sleeve body
There are one the soft overlay film body made of flexible material, the both ends of the soft overlay film body are close with hard sleeve body respectively
Envelope, there are one flow-guiding channel, the flow-guiding channel and soft overlay film sets for setting between hard sleeve body and soft overlay film body
Body inner space communicates, and one end of flow-guiding channel is connect with a check valve, and the check valve is connected on hard sleeve body,
The rear part is in coniform after soft overlay film body gassy or liquid.
Further, described hard sleeve body one end is equipped with the casing seat passed through for puncturing lever.
Further, all outer circumferential phases with hard sleeve body both ends inwardly at the soft overlay film body both ends
Bonding or hot pressing connects.
Further, the flow-guiding channel includes be arranged in the outer wall of hard sleeve body one section along hard sleeve body
Axially extending diversion trench, soft overlay film body close the notch of the diversion trench.
The operation principle of the utility model is：In minimal invasive surgical procedures, hard sleeve body is together with unaerated or non-filling liquid
Soft overlay film body be placed in stomach wall puncture, after the inflation of soft overlay film body or filling liquid, soft overlay film body expansion, to stamp
Hole generates pressure, to fix hard sleeve body, and puncture is sealed.The rear part is in circular cone after soft overlay film body expansion
Shape forms conical surface seal, hard sleeve body fixes relatively reliable, better tightness under intra-abdominal pressure with stomach wall puncture.
The utility model compares with prior art, and effect is positive and apparent.The utility model is in hard sleeve
Soft overlay film body is arranged in the outside of body, and the rear part is in coniform, hard set after soft overlay film body gassy or liquid
Tube body together with unaerated either non-filling liquid soft overlay film body merging stomach wall puncture after to soft overlay film body inflate or fill
Liquid, soft overlay film body expansion, generates pressure to puncture, to fix hard sleeve body, and puncture is sealed.It is soft to cover
The rear part is in coniform after the expansion of Membrane cover body, under intra-abdominal pressure, forms conical surface seal with stomach wall puncture, hard sleeve body is solid
Fixed relatively reliable, better tightness.
Description of the drawings：
Fig. 1 is that the expansion type of the utility model fixes the schematic diagram of puncture outfit.
Specific implementation mode：
Embodiment 1:
As shown in Figure 1, the expansion type of the utility model fixes puncture outfit, including puncture cannula 1 and it is threaded through puncture cannula 1
Interior puncturing lever 2, the puncture cannula 1 include tubular hard sleeve body 3, wherein in the hard sleeve body 3
Outer circumferential is arranged there are one the soft overlay film body 4 made of flexible material, and the both ends of the soft overlay film body 4 are distinguished
It is sealed with hard sleeve body 3, there are one flow-guiding channels 5 for setting between hard sleeve body 3 and soft overlay film body 4, and described leads
Circulation road 5 is communicated with soft 4 inner space of overlay film body, and one end of flow-guiding channel 5 is connect with a check valve 6, the list
It is connected on hard sleeve body 3 to valve 6, the rear part is in coniform after soft 4 gassy of overlay film body or liquid.
Further, described 3 one end of hard sleeve body is equipped with the casing seat passed through for puncturing lever 2.
Further, all outer circumferentials with 3 both ends of hard sleeve body inwardly at soft 4 both ends of overlay film body
Bonding or hot pressing connects.
Further, the flow-guiding channel 5 includes be arranged in the outer wall of hard sleeve body 3 one section along hard sleeve
The axially extending diversion trench of body 3, soft overlay film body 4 close the notch of the diversion trench.
The operation principle of the present embodiment is：In minimal invasive surgical procedures, hard sleeve body 3 is together with unaerated or non-filling liquid
Soft overlay film body 4 is placed in stomach wall puncture, and after the inflation of soft overlay film body 4 or filling liquid, soft overlay film body 4 expands, right
Puncture generates pressure, to fix hard sleeve body 3, and puncture is sealed.The rear part is in after soft overlay film body 4 expands
It is coniform, under intra-abdominal pressure, conical surface seal is formed with stomach wall puncture, hard sleeve body 3 is fixed relatively reliable, and leakproofness is more
It is good.
