Description
Technical field
The utility model is related to field of medical products, and in particular to a kind of stitching devices for Minimally Invasive Surgery.
Background technology
Minimally Invasive Surgery, as the term suggests it is exactly the operation of microtrauma.Refer to utilizing the modern medical services devices such as laparoscope, thoracoscope
The operation that tool and relevant device carry out.
It improves with the development of science and technology, " minimally invasive " this concept has been deep into the various fields of surgical operation, monitoring
System is also not limited to endoscope, is more by the way of intervention, such as spinal surgery, orthopaedics.Also other modes, it is such as micro-
Surgery is widely used in hand surgery etc..
Minimally Invasive Surgery refers to the operation carried out using the modern medical equipments such as laparoscope, thoracoscope and relevant device.It is minimally invasive
The appearance of surgery and medical domain extensive use be the nearest more than ten years thing.
Minimally Invasive Surgery more focuses on the psychology of patient, society, physiology（Pain）, mental outlook, the improvement of quality of life and health
It is multiple, it utmostly shows a patient every consideration, mitigates the pain of patient.Minimally Invasive Surgery need not operate on, and 1-3 0.5- only need to be opened with patient
1 centimetre of aperture, patient's preventing from scar, it is painless, only need to complete within 3-5 days to check, treat, rehabilitation overall process.It reduces
Injury of the traditional operation to human body considerably reduces disease to patient to the inconvenience and pain come.Minimally Invasive Surgery has wound
Hinder the superiority that small, pain is light, recovery is fast.
However, there are currently no the stitching devices for Minimally Invasive Surgery, when Minimally Invasive Surgery sutures, conventional sewing needle cannot
It is advantageously used.
Utility model content
In order to overcome the shortcomings of that background technology, the utility model provide a kind of stitching devices for Minimally Invasive Surgery, mainly
Solve the problem of that the sewing needle conventional when Minimally Invasive Surgery sutures cannot be advantageously used.
Technical solution used by the utility model is：
A kind of stitching devices for Minimally Invasive Surgery, including it is internally provided with the tube body of liquid, including tube body includes the first pipe,
First pipe both ends are equipped with the second pipe upwardly extended and third pipe,
The first piston of sealing cooperation is equipped in second pipe, the first piston is equipped with piston rod, the piston rod
Expose in the second pipe upper end for pressing upper end；
The second piston of sealing cooperation is equipped in the third pipe, the second piston upper end is equipped with being used for for releasable connection
The sewing needle of threading；
The sewing needle includes first position when the second piston bar declines in the third pipe and described
Second piston rises from the second position of the third pipe when rising.
The utility model has the beneficial effects that：The utility model provides a kind of stitching devices for Minimally Invasive Surgery, makes
With when, tube body is stretched into the wound of patient, and need to be pierced by below the skin of syringe needle reaching third pipe, is pressed at this time
Piston rod, first piston is pressed to decline, jack up second piston by liquid, the sewing needle emersion third pipe in second piston punctures
Skin exposes outside, then takes out the line on syringe needle, simple in structure, easy to use.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Fig. 2 is the enlarged diagram at Figure 1A.
Specific implementation mode
Utility model is described further below in conjunction with the accompanying drawings：As shown, a kind of suture for Minimally Invasive Surgery fills
It sets, including is internally provided with the tube body 1 of liquid 9, including tube body 1 includes the first pipe 11, first pipe both ends are equipped with and upwardly extend
The second pipe 12 and third pipe 13, the first piston 121 of sealing cooperation is equipped in second pipe 12, the first piston is equipped with
Piston rod 122, the piston rod upper end are exposed in the second pipe upper end for pressing；Sealing cooperation is equipped in the third pipe 13
Second piston 131,131 upper end of the second piston are equipped with the sewing needle 4 for threading of releasable connection；The sewing needle includes
When first position and the second piston when the second piston bar declines in the third pipe rise described in emersion
The second position of third pipe.When in use, tube body is stretched into the wound of patient,（Syringe needle does not reveal in third pipe at this time
Go out）, and need to be pierced by below the skin of syringe needle reaching third pipe, piston rod is pressed at this time, and first piston declines, and passes through stream
Matter jacks up second piston, and the sewing needle emersion third pipe in second piston punctures skin and exposes outside, then will be on syringe needle
Line takes out, and other direction is similarly, simple in structure, easy to use, and first piston and second piston can be made of rubber, protects
Demonstrate,prove its leakproofness.
In the present embodiment, as shown, the third inside pipe wall is additionally provided with spacing ring 133, the internal diameter of the spacing ring
Less than the diameter of the second piston.It can be limited ring blocking when second piston rises, prevent from dropping out, be easy to use.
In the present embodiment, it is used as shown, being equipped between the second piston upper surface and the spacing ring lower face
In the elastic component 5 to exert a force downwards to the second piston.The effect resetted may be implemented, more convenient to use, which can
Think shrapnel, rubber ring, spring etc..
In the present embodiment, as shown, the elastic component is spring.Preferably, herein using spring, cost
It is relatively low, it is easy to process.As one of embodiment, both ends of the spring can be welded on spacing ring and second piston.
In the present embodiment, as shown, the second piston upper end is additionally provided with mounting hole 132,4 bottom of the sewing needle
