Description

A kind of dedicated cornua uteri clamp of sheep embryo transfer

Technical field:

The utility model belongs to sheep embryo transfer technology field more particularly to a kind of dedicated cornua uteri folder of sheep embryo transfer Pincers.

Background technique:

Rate of fertilization can be improved in the laparoscope cornua uteri insemination technique of sheep, increase can use the quantity of embryo, it is more to reduce Caused by secondary breeding stress, a possibility that it is small that the technology wound is small, uterus is exposed to outer area, and the operating time is short, infection, subtracts It is low, therefore be widely used；Its specific operation is: in the mouth for opening 2cm or so away from sheep left breast 10-15cm, then away from Sheep right breast 10-15cm opens the mouth of 2cm or so, and in left side, opening insertion laparoscope finds cornua uteri, at right openings Cornua uteri is pulled out using uterus clamp and obtains embryo；All than relatively sharp, cornua uteri is easy broken on the head of existing uterus clamp Damage, increases the probability of wound infection, although part uterus clamp also can be avoided cornua uteri breakage, will appear and clamped Cornua uteri is easily easy the phenomenon that sliding in journey；It is all one-handed performance (a hand hand-held endoscope, another when additionally, due to operation Hand is clamped using uterus), if not paying attention to, uterus pincers are possible to take instead, make troubles to transplanting work, reduce the work of embryo transfer Make efficiency.

Utility model content:

The purpose of this utility model is to provide a kind of dedicated cornua uteri clamps of sheep embryo transfer.

The utility model is implemented by following technical solution: a kind of dedicated cornua uteri clamp of sheep embryo transfer comprising clamp Handle and stapling head, the clamp handle altogether there are two, each clamp handle successively by handle, limit handle and claw beam form, it is described Handle, the limit handle and the claw beam are in the same plane, and two clamp handles are living with pin in the middle part of the claw beam Dynamic connection, the stapling head share two pairs, and each pair of stapling head includes angle rod and oval folder composition, is pressed from both sides described in one pair of them Binding clip and the angle of plane locating for the handle, limit handle, the claw beam are 20 °~60 °, stapling head described in another pair and institute Stating handle, limiting the angle of plane locating for handle, the claw beam is -20 °~-60 °, and the clamping face of each pair of oval folder is wave Shape.

Further, it is the iron-sand of 0.1~0.3mm that sandblasting, which has partial size, on the clamping face of the oval folder.

The advantages of the utility model: wavy oval folder and the clamping face with circular arc chamfering not only increase clamping table Area and can prevent damage cornua uteri；Sandblasting has iron-sand on the clamping face of oval folder, increases clamping friction power, makes uterus Angle should not slide；Two-way clip designs make operator that need not consider the direction held, are easy to use, increase the work of embryo transfer Make efficiency.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model.

In figure: clamp handle 1, stapling head 2, handle 1-1, limit handle 1-2, claw beam 1-3, pin 3, angle rod 4, oval folder 5.

Specific embodiment:

As shown in Figure 1, a kind of dedicated cornua uteri clamp of sheep embryo transfer comprising clamp handle 1 and stapling head 2, clamp handle 1 altogether there are two, each clamp handle 1 successively by handle 1-1, limit handle 1-2 and claw beam 1-3 form, handle 1-1, limit handle 1-2 and Claw beam 1-3 is in the same plane, and two clamp handles 1 are flexibly connected in the middle part of claw beam 1-3 with pin 3, and stapling head 2 shares two Right, each pair of stapling head 2 includes 5 composition of angle rod 4 and oval folder, one pair of them stapling head 2 and handle 1-1, limit handle 1-2, pincers The angle of plane locating for bar 1-3 is 28 °, another pair stapling head 2 and handle 1-1, the angle for limiting plane locating for handle 1-2, claw beam 1-3 Degree is -28 °, and the clamping face of each pair of oval folder 5 is waveform, and it is 0.1~0.3mm that sandblasting, which has partial size, on the clamping face of oval folder 5 Iron-sand；Working principle: left hand hand hand-held endoscope finds cornua uteri, and another hand (need not be considered using cornua uteri clamp The direction of gripping), cornua uteri is clamped using oval folder 5, wavy oval folder 5 and the clamping face with circular arc chamfering not only increase The area of clamping face is added and damage cornua uteri can be prevented；Sandblasting has iron-sand on the clamping face of oval folder 1, increases clamping Frictional force slide cornua uteri should not.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
