Description
Technical field
The utility model relates to field of medical products, and in particular to a kind of puncture needle handle.
Background technique
Abdominal puncture needle is a kind of surgical instrument in Minimally Invasive Surgery for establishing into the artificial channel of body cavity.Micro-
When creating laparoscopic medical operation beginning, elder generation is near patient affected part or navel menisectomy knife does a small notch, then lifts stomach wall,
It holds puncture outfit and is pierced into abdominal cavity, be inserted into abdominal cavity in a flash, resistance moment reduces, and the puncture needle generally comprises puncture needle sheet
Body and handle, conventional handle is the Paracentesis needle holder directly connecting with puncture needle at present, has the following deficiencies: that 1. users are difficult to
Effectively control is exerted oneself, and current improvement is also only limitted to that antifriction face is arranged on Paracentesis needle holder；2. it is micro- to cooperate at present non-blind to wear
Wound generally requires and imaging device channels is arranged in Paracentesis needle holder, because the placement of palm is inconvenient.
Summary of the invention
The utility model provides a kind of puncture needle handle, which includes Paracentesis needle holder and lever, the Paracentesis needle holder and
Lever connection, the length of the lever are 35~45cm；The lever central region be equipped with arc convex, the arc convex with
Inner concave is formed between Paracentesis needle holder, the arc convex bends backward extension.
Preferably, the left and right side of the lever is in the curved surface slightly to concave.
Preferably, the Paracentesis needle holder and lever are integrally formed.
Preferably, the Paracentesis needle holder is extended downwardly equipped with instrument channel, it is applicable in blind threading method or non-blind threading method.
Preferably, the bottom surface of the lever is hollow structure, overall structure is light.
Compared with prior art, the utility model has the following beneficial effects:
Puncture needle handle provided by the utility model uses airflow design, and finds by clinical research, the length of lever
When degree is 35~45cm, meets the holding mode of ergonomics and have the effect of facilitating force；Paracentesis needle holder is logical equipped with instrument
Road, for planting the imaging devices such as endoscope；I.e. clinically, puncture needle handle provided by the utility model may be used for blind
Threading method can be used for non-blind threading method；And overall structure is both artistic and practical, it is light portable.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of puncture needle handle provided by the utility model；
Fig. 2 is a kind of side view of puncture needle handle provided by the utility model；
Fig. 3 is a kind of top view of puncture needle handle provided by the utility model；
Fig. 4 is the main view of non-blind threading method hold；
Fig. 5 is the 45o multi-angled view of non-blind threading method hold；
Fig. 6 is the schematic diagram of blind threading method hold.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
Cited such as "upper" in the utility model, "lower", "left", "right", " in " term, be merely convenient to describe
Be illustrated, and do not have limit the scope of the utility model effect.
A kind of puncture needle handle, the handle include Paracentesis needle holder 4 and lever 3, and the lever 3 connects with 4 side of Paracentesis needle holder
It connects, the length of the lever 3 is 35~45cm；3 central region of lever is equipped with arc convex 31, the arc convex 31 with
Form inner sunken face between Paracentesis needle holder 4, the arc convex 31 bends backward extension, entire lever at airflow design, with
The hand physiology of people is adapted to, and through the multiple PRACTICE OF DESIGN of inventor, discovery is conveniently applied when the length of the lever is 35~55cm
Control is summed it up, the design of ergonomics is met, the left and right side of the lever 3 is in slightly inside concave surface 32,33, facilitates hand
Refer to clamping, it is preferable that the Paracentesis needle holder 4 is integrally formed with lever 3.
The Paracentesis needle holder central area, which extends downwardly, is equipped with axial imaging instrument channel 41, Paracentesis needle holder 4 and puncture needle
Connection, for the plant of the imaging devices such as endoscope, convenient for users to the puncture situation of Minimally Invasive Surgery can be grasped at any time.It is preferred that
Ground, Paracentesis needle holder 4 and lever 3 are integrally formed.
The bottom surface of the lever 3 is hollow structure, and structure is simple, light weight.
According to whether deploying endoscope, puncture needle handle provided by the utility model has following two application method:
Non-blind threading method: being inserted into endoscope in Paracentesis needle holder, at this time scape of the doctor when puncturing, before can observing endoscope
As whether, doctor is to completing to be punctured with and get information about.Specific operating method are as follows: held as shown in figure 3, palm center is against
The arc convex of handle, as shown in figure 4, head on the edge of Paracentesis needle holder through-hole at tiger's jaw, by the inside and outside rotation of wrist, using wearing
The lower part of pricker pushes musculature aside, then struts musculature by the middle part being gradually expanded；Such hold to puncture
It is more laborsaving.
Blind threading method: puncture outfit mismatches endoscope use；As shown in figure 5, by lever and puncture needle is pressed at the tiger's jaw of hand
On the curved surface being recessed between seat, doctor firmly completes to puncture by the centre of the palm.It pushes the lower part of puncture needle aside musculature, then passes through
The middle part and lower part become larger struts musculature, and power thrusts are consistent with direction is punctured.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.If this field is general
Logical technical staff is enlightened by it, without deviating from the purpose of the present invention, is not inventively designed and is somebody's turn to do
The similar frame mode of technical solution and embodiment, all should belong to the protection range of the utility model.
