Description
Technical field
The present invention relates to a kind of laparoscope puncture outfits.
Background technique
Laparoscope puncture outfit is a kind of disposable, the conveying of gas and endoscope suitable for micro-wound surgical operation
It is minimally invasive from the creation in the channel of external world's disengaging body cavity, various laparoscopic surgeries, including needle holder being applied to surgery Minimally, gynaecology with surgical instrument
Operation, thoracic surgery, the endoscope-assistant surgeries such as Urology Surgery can match with domestic and international various laparoscope television systems.
Although laparoscope puncture outfit belong to it is minimally invasive, but still can on human body scar influence it is beautiful, it is therefore desirable to the greatest extent
It is possible to reduce the number and hole punctured.In addition, since tissue has good toughness, in order to reach minimally invasive effect,
Reach aesthetic effect, the wound and very little of patient, so doctor's skin histology when puncturing can generate very big resistance, greatly
The difficulty of operation puncturing is increased greatly.In clinical operation, laparoscope puncture outfit should have well when puncturing skin
Sharpness it is smooth to guarantee that doctor punctures, while completing in a flash puncturing, and must assure that and do not puncture human body viscera tissue.
Summary of the invention
In view of this, the present invention provide it is a kind of subtract hole laparoscope puncture outfit with protective case, sleeve can accommodate two behaviour
Make equipment while entering, reduces the quantity of puncture time and puncturing hole.Its tip for being used to puncture is puncturing completion simultaneously
It can be covered by protection sliding sleeve in a flash, avoid stabbing (incised wound) internal organ.
In order to solve the above technical problems, the technical scheme is that being punctured using a kind of hole laparoscope that subtracts with protective case
Device including sleeve and inserts in rod-shaped inner core in sleeve；The sleeve top is provided with receiver, installs on the receiver
There is intake valve；The inner core top is provided with the top cover for connecting with receiver, and lower end is the tip for puncture；The set
The cross section of cylinder is ellipse, and bar portion cross-sectional shape and the sleeve of the inner core match；The bar portion lower end is located at tip
It is provided with annular groove outside, protection sliding sleeve is provided in the groove, the protection sliding sleeve can be slided up and down along groove；The groove
It is interior to be located at the driving spring being provided with above protection sliding sleeve for sliding sleeve be protected to eject outward；The inner core be it is hollow, in
Portion is provided with axial core bar, and the core bar can be slided up and down along inner core；The core bar lower end is provided with elastic slice, and the protection is slided
It is provided with location hole on set side wall, the elastic slice, which may extend into location hole, will protect sliding sleeve stuck；It is provided with below the core bar
Top cover is extended on reset spring, core bar top.The present invention subtracts hole design due to having done, in order to accommodate two operational instrument simultaneously
Into, to the inner hole of sleeve carry out more increasing.It is gone on smoothly in order to enable puncturing, tip needs more sharp.It carries out
When puncture, pressing core bar to receive the location hole for being detached from protection sliding sleeve in elastic slice, and protection sliding sleeve is move freely.It is wearing
During thorn, core bar is decontroled, due to the resistance of tissue, so that protection sliding sleeve bounces back tip exposure always.Work as tip
After puncturing human abdominal cavity, resistance disappears, and protects to pop up rapidly under the action of sliding over driving spring and covers tip, and elastic slice
It is caught in location hole, will not bounce back touching internal organ protection sliding sleeve again at this time.
As an improvement the elastic slice end is provided with locating piece.Pass through the location hole on locating piece and protection sliding sleeve
Cooperation positioning, so that the protection more difficult retraction of sliding sleeve.
As a kind of further improvement, the locating piece is right angled triangle, and right-angle side is downward, and bevel edge is upward.Such as
This is arranged so that protection sliding sleeve can not bounce back, and not stop its pop-up.
As another further improvement, the elastic slice and core bar axis are at an acute angle.When pressing core bar very
It is easy inwardly to collapse the range for being detached from location hole with spring plate, and protection slides over when being returned back to top due to Impact direction not
Together, elastic slice top can not be returned.
As an improvement the elastic slice is two pieces of left and right, the location hole on the protection sliding sleeve is also left and right two.It protects
It is fixed to keep steady, and avoids unilateral.
As an improvement the length that the protection sliding sleeve extends inner core is greater than the length at tip.Ensure that tip is being protected
It protects in the protection scope of sliding sleeve.
As an improvement the oval inner hole long axis of the sleeve is 1.5 centimetres, short axle is 0.75 centimetre.So that set
Cylinder can accommodate two surgical instruments while operate.
As an improvement the inner core tip is cross blade.Convenient for cutting tissue, venipuncture difficulty is reduced.Due to
Tip can be arranged quite sharp by the presence of protective case without scruple, and the general tip of existing puncture outfit is all more blunt,
Primarily to avoiding accidentally injuring.
The invention has the beneficial effects that: the laparoscope puncture outfit with above structure increases the cross section of sleeve
Product, can accommodate two surgical instruments simultaneously and be operated.Reduce the number of puncture and the quantity of puncturing hole, mitigates
The pain of patient is also more beautiful.Meanwhile protection sliding sleeve is provided at inner core tip, puncturing a flash for entering abdominal cavity
Between tip can be covered, avoid its hurt or stab internal organ, greatly reduce the probability of happening of malpractice.
