Vessel forceps could be passed through below blood vessel after blood vessel, so that pass suture through, it is big to tissue damage；2nd, when wearing suture, easily press from both sides by mistake
Tissues surrounding vascular, and suture easily comes off, operation repeatedly easily causes tissue damage and expends operating time；3rd, separation compared with
Blood vessel and damaging surrounding tissue are more easily caused during thin vessels.
The content of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided one kind can simplify snare blood vessel
Process, the blood vessel snare pin for reducing tissue damage.
According to technical solution provided by the utility model：Blood vessel snare pin, it is characterised in that：Including needle body and needle handle, institute
State line part and bending section, the needle handle of the needle body including integrally connected and be fixedly connected on needle body tail end, the bending section includes
The first bending section and the second bending section of arc-shaped transition connection, the first bending section are connected as a single entity with needle body front end, the second bending
Section is equipped with pin hole, is in 30~60 ° of angle between the second bending section and needle body line part axis.
As further improvement of the utility model, the angle between the second bending section and needle body the line part axis is
45°。
As further improvement of the utility model, second bending section is set to bluff body, and the pin hole is positioned at flat
In vivo.
It it is in 30~60 ° as further improvement of the utility model, between the flat horizontal surface and body flat of the bluff body
Angle.
As further improvement of the utility model, the angle between the flat horizontal surface and body flat of the bluff body is
45°。
As further improvement of the utility model, the pin hole is oval in the axial direction of the second bending section.
As further improvement of the utility model, the pin hole is in radially hourglass shape the second bending section.
As further improvement of the utility model, the line part is cylinder.
As further improvement of the utility model, the needle handle is equipped with anti-skid chequer.
As further improvement of the utility model, the anti-skid chequer is latticed anti-skid chequer.
As further improvement of the utility model, the second bending segment length is 0.5cm, width 0.15cm；Institute
It is 0.3cm, minor axis 0.06cm to state pin hole major diameter.
The utility model compared with prior art, has the following advantages that：
The utility model clever structure, can pass through below blood vessel easily after simple separation tissues surrounding vascular,
Pin hole withdraws needle body i.e. by suture from blood vessel lower section through taking back after penetrating suture, so as to reduce damaging surrounding tissue, simplification is worn
Line process.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
As shown in the figure：Blood vessel snare pin in embodiment is mainly made of needle body 1 and needle handle 2, and the needle body 1 includes one
The line part 1a and bending section 1b of connection, the needle handle 2 are fixedly connected on 1 tail end of needle body, and the bending section 1b includes arc-shaped
The the first bending section 1b.1 and the second bending section 1b.2, the first bending section 1b.1 of transition connection are connected as a single entity with 1 front end of needle body, the
Two bending section 1b.2 are equipped with pin hole 3, are in 30~60 ° of angle between 1 line part 1a axis of the second bending section 1b.2 and needle body.
In the utility model, the angle between 1 line part 1a axis of the second bending section 1b.2 and needle body should not be too large also not
Preferably too small, angle is excessive, and blood vessel easily slips, and is not unfavorable for threading；Angle too small, then be unfavorable for the second bending section 1b.2 from
Passed through below blood vessel, difficulty is brought to clinical manipulation.Preferably, the second bending section 1b.2 and 1 line part 1a axis of needle body
Angle between line is preferably 45 °.
As shown in Figure 1, in the present embodiment, the second bending section 1b.2 is set to bluff body, and the pin hole 3 is located at bluff body
It is interior.Second bending section 1b.2, which is arranged to bluff body, can expand the setting size of pin hole 3, convenient threading as far as possible.
As shown in Figure 1, it is in 30~60 ° of folder in the present embodiment, between 1 plane of flat horizontal surface and needle body of the bluff body
Angle.By using this structure design, in clinical manipulation, doctor positive can face the operation such as pin hole 3, convenient threading.Make
For preferred solution, the angle between 1 plane of flat horizontal surface and needle body of bluff body is preferably 45 °.
As shown in Figure 1, in the present embodiment, the pin hole 3 is oval in the axial direction of the second bending section 1b.2, pin hole 3
What it is in the second bending section 1b.2 is in radially hourglass shape.It is convenient that such structure design can give threading operation to provide.
As shown in Figure 1, in the present embodiment, the line part 1a is cylinder, and line part 1a length is 8cm, a diameter of
0.1cm.2 length of needle handle is 2cm, and a diameter of 0.8cm, needle handle 2 is equipped with the anti-skid chequer for facilitating doctor's grip.It is described anti-skidding
Line is preferably arranged to latticed anti-skid chequer.The second bending section 1b.2 length is 0.5cm, width 0.15cm；The pin hole 3
Major diameter is 0.3cm, minor axis 0.06cm.
During concrete application, first separated using vessel forceps or tweezers, exposure target vessel, then hold the needle handle of blood vessel snare pin
