Example 1

The specific implementation of the utility model is shown in fig. 1-4, a pair of minimally invasive surgery forceps, which comprises two cross hinged forceps bodies 1, wherein the two forceps bodies 1 are hinged in an X shape, and constitute the main structure of the forceps. The clamp body 1 comprises a holding handle 2 and a clamping arm 3 which are arranged at two sides of a hinge point. When the medical staff uses the operating forceps, the holding handle 2 is held, and the clamping arm 3 is controlled to clamp human tissues by controlling the opening and closing of the holding handle 2.

Wherein, the hinge point of two pincers bodies is equipped with the hinge mechanisms 4 that can quick detach. In a minimally invasive surgery, the two forceps bodies 1 can be detached through the quick-detachable hinge mechanism 4, the clamping arm 3 of one of the forceps bodies 1 is placed below a clamped tissue, the clamping arm 3 of the other forceps body 1 is placed above the clamped tissue, and the clamped tissue is taken out or taken out to the superficial abdominal surface for facilitating the surgical operation. Convenient to use can also avoid simultaneously when meetting the great condition of tissue, organ, parcel piece, the unable problem of directly clinching the tissue of getting into the incision of pincers body 1. Moreover, the single split forceps body 1 can be used as an operation baffle plate and other operations.

Simultaneously, two arm lock 3 all is arc and the relative setting of intrados. The free ends of the two clamping arms 3 are provided with clamping rings 32, and the two clamping rings 32 are arranged oppositely. Because arm lock 3 is the arc, cooperation clamping ring 32, the centre gripping area compares in current operation pincers greatly increased, and the centre gripping that can be stable is lived the tissue, and can not constitute secondary damage to the tissue. Meanwhile, the tissue is clamped by the clamping ring 32, and the operation of cutting or suturing and the like by medical staff through the middle through opening of the clamping ring 32 is facilitated.

The hinge mechanism 4 includes a mounting bayonet 41 provided on one of the forceps bodies 1, and a mounting adapter 42 detachably inserted into the mounting bayonet 41 is provided on the other forceps body 1. The installation bayonet 41 and the installation joint 42 are in quick-release type insertion fit, so that the clamp body 1 is convenient to disassemble and assemble.

An elastic layer 411 is arranged on the inner wall of the mounting bayonet 41. Specifically, the elastic layer 411 is made of an elastic material such as rubber or silicone. Since the elastic layer 411 has a certain expansion and contraction characteristic, the mounting tab 42 can be stably fixed in the mounting notch 41, and is prevented from falling off.

In this embodiment, the mounting bayonet 41 is spherical, and the mounting joint 42 is a ball head. Of course, in the actual process of manufacturing the caliper body 1, the specific shapes of the mounting bayonets 41 and the mounting tabs 42 can be selected according to actual conditions, and are not limited to the spherical grooves and the spherical heads.

In addition, a flexible portion 31 capable of adjusting the radian is provided at the connection between the clip arm 3 and the clip ring 32. The flexible portion 31 is made of a flexible metal with a certain toughness, such as copper or titanium alloy. Because this flexible portion 31 has certain toughness, medical personnel can be according to the needs of actual conditions (like the size of package piece), through the mode of manual bending, crooked flexible portion 31, and then reach the purpose of adjusting 3 radians of arm lock and the 32 centre gripping angles of grip ring, be convenient for wrap around and clamp by the centre gripping tissue, can also avoid causing the damage to by the centre gripping tissue when the centre gripping is stable.

In this embodiment, the opposite surfaces of the two clamping rings 32 are provided with anti-slip teeth, so that the whole clamped tissue does not slip or fall off in the clamping process.

It should be noted that:

in this embodiment, a fixing buckle 21 capable of locking the two handles 2 is disposed between the two handles 2. The fixing buckle 21 specifically includes two positioning teeth 211 respectively disposed on the two handles 2 and capable of engaging with each other. After the two clamping arms 3 clamp the human tissue, the medical staff can lock the position of the holding handle 2 through the positioning teeth 211. Is convenient to operate, and does not need medical care personnel to continuously apply force in the process of using the surgical forceps.

Meanwhile, there is a point about the grip 2 — the grip 2 in this embodiment is arc-shaped and the intrados are arranged oppositely. The holding handle 2 arranged in this way can be convenient for the medical staff to operate and hold, namely the medical staff generally operates the operation forceps by one hand when performing the operation. When the traditional linear type grip handle is operated by a single hand, the opening degree of the clamping arm 3 is easily limited and cannot reach the maximum opening degree during design. The grip handle 2 adopting the arc design can greatly relieve the problem, so that the clamping arm 3 can be opened as much as possible.

Example 2

As shown in fig. 4, the present embodiment is different from embodiment 1 in that: in embodiment 1, two positioning teeth 211 which are respectively arranged on two handles 2 and can be engaged with each other are used to lock and fix the two handles 2, which belongs to rigid locking. In the present embodiment, a tension spring 22 capable of tightening the two handles 2 is disposed between the two handles 2, and two ends of the tension spring 22 are respectively connected to the two handles 2.

When the medical staff controls the clamping arm 3 to open, the tension spring 22 is stretched; after clamping human tissue, because arm lock 3 still can be in a state that part is opened, extension spring 22 can exert a power of tightening up to grip 2 this moment, and then need not medical personnel's application of force and also can tighten up arm lock 3, stable centre gripping human tissue. Since the tension spring 22 is a structural element with a certain extensibility, when the clamping arm 3 is tightened by the force of the tension spring 22 to clamp human tissue, the clamping arm is elastically tightened. Therefore, the surgical forceps can better clamp human tissues, the size and the shape of the clamped tissues are uncertain, and the elastic tightening can enable the surgical forceps to be adaptive to the size and stably clamp various human tissues when facing the human tissues. Meanwhile, the elastic tightening also avoids the phenomenon that the clamping ring 32 on the clamping arm 3 clamps the tissues of the human body too tightly to cause damage to the tissues.

Regarding the installation of the tension spring 22, a ring may be provided on each of the opposite sides of the two grips 2. Then the two ends of the tension spring 22 are respectively hooked on the two circular rings.

The present invention has been described above with reference to the preferred embodiments, but the present invention is not limited to the above-disclosed embodiments, and various modifications, equivalent combinations, which are made according to the essence of the present invention, should be covered.
