Description
Technical field
The utility model is related to medical instruments field, specially a kind of disposable bent puncture outfit.
Background technology
Puncture outfit is a kind of outer laparoscope instrument, and it is suitable for establishing abdomen in celioscopy and surgical procedure
It uses in chamber surgical work channel.There are obvious shortcomings in structure for existing puncture outfit：1, casing is made of hard material, cannot be rolled over
It is curved, it cannot be by the surgical instrument of bending, using extremely just；2, the bushing outer surface of puncture outfit is smooth smooth surface, is being performed the operation
In often there is a problem：I.e. after sleeve has been placed in body cavity, since doctor often rotates medical instrument, drive is worn
The rotation of device sleeve is pierced, to make casing skid off in vitro, causes abdominal cavity to be lost heart, influences procedure；3, puncture outfit is being performed the operation
When puncture, it is located at the binding site for puncturing conehead rear end of the front port and puncturing lever of casing due to exhaust position, in this way cannot
Ensure to wear out in the first time of peritonaeum in puncturing head and gas is filled between internal organ and peritonaeum, makes it easy to internally dirty make in this way
At damage.
Utility model content
The purpose of this utility model is to provide a kind of disposable bent puncture outfit, can effectively solve institute in background technology
There are the problem of.
Realizing the technical solution of above-mentioned purpose is：Disposable bent puncture outfit, including puncture cannula component and for covering
Puncture bar assembly in puncture cannula component, the puncture cannula component include casing seat and casing, the puncturing lever group
Part includes pole cap and puncturing lever, it is characterised in that：Described sleeve pipe uses bent hose.
Further, the puncturing lever is hollow lever, and puncturing lever is provided with multiple air admission holes, puncturing lever along length is rectangular
It is evenly equipped with multiple flanks the ring week at tip, air flue is equipped in flank, the axis of air flue is parallel with the axis of flank, and air flue is close to be worn
The one end at thorn stick tip penetrates through flank, and the other end is connected to the inner cavity of puncturing lever.
Further, it is provided with multi-ring annular rib on the outer wall of described sleeve pipe.
Further, the section of the circumferential rib is arc-shaped.
The beneficial effects of the utility model：
1, the casing of the utility model uses bent hose so that the surgical instrument of bending can be entered when operation,
Using more flexible, conveniently, keep surgical procedure more smooth, reduce operating time, alleviate patient's pain.
2, multiple air admission holes are arranged in the utility model on the body of rod, and puncturing lever tip is provided with the gas being connected to air admission hole
Road is entered in the inner cavity of puncturing lever, then from point in this way, from the gas that the gas injection valve on puncture outfit injects by air admission hole
The air flue at end is discharged towards operative site, and the first time that peritonaeum is worn out to may be implemented in puncturing lever is inflated, and makes internal organ
It is quickly separated in time with peritonaeum, and then puncturing lever is prevented to cause to damage to internal organ.
3, it is provided with multi-ring annular rib on the outer wall of casing, it is ensured that position is relatively more fixed in the course of surgery for casing,
It will not skid off.And section setting is arc-shaped, it is ensured that casing is more smooth when into and out tissue, reduces to bodily tissue
Damage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the front view of puncture cannula component.
Specific implementation mode
As shown in Figure 1, 2, the utility model includes puncture cannula component 1 and for being sleeved in puncture cannula component 1
Bar assembly 2 is punctured, puncture cannula component 1 includes casing seat 11 and casing 12, and gas injection valve 3, casing 12 are connected on casing seat 11
Using bent hose, multi-ring annular rib 13 is provided on the outer wall of described sleeve pipe 12, circumferential rib 13 can ensure that casing exists
Position is relatively more fixed in surgical procedure, will not skid off；The section of circumferential rib 13 is arc-shaped, it is ensured that casing 12 is being inserted into and is pulling out
Go out more smooth when tissue, damage of the reduction to bodily tissue.
It includes pole cap 21 and puncturing lever 22 to puncture bar assembly 2, and puncturing lever 22 is hollow lever, and puncturing lever 22 is rectangular along length
Multiple air admission holes 23 are provided with, the tip of puncturing lever 22 is evenly equipped with multiple flanks 24 ring week, air flue 25 is equipped in flank 24,
The axis of air flue 25 is parallel with the axis of flank 24, and air flue 24 penetrates through flank 24, the other end close to the one end at 22 tip of puncturing lever
It is connected to the inner cavity of puncturing lever 22.
When in use, the gas injected from gas injection valve 3 enters the inner cavity of puncturing lever 22 by air admission hole 23 to puncture outfit
In, it is then discharged from the air flue at tip 25 towards operative site, to may be implemented in the first time that puncturing lever 22 wears out peritonaeum
It is inflated, so that internal organ is quickly separated in time with peritonaeum, and then puncturing lever 22 is prevented to cause to damage to internal organ.
