Description

Fixed pincers of buckle for thoracic surgery

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a buckle-fixed type clamp for thoracic surgery.

Background

Forceps are forceps-like instruments that rely on mechanical action between their jaws to grasp, clamp, and contract tissue. Common surgical forceps, the finger embolias the dactylotheca intra-annular during use, needs the doctor to point the portion application of force to press from both sides and holds between the fingers, and the in-service use discovery is held between the fingers needs to point the portion to increase application of force dynamics for firm clamp, and long-time operation not only can increase fatigue degree, and relevant human tissue has the mucus moreover, applys finger portion dynamics by a wide margin and destroys human tissue and difficult firm clamp and hold between the fingers. In order to solve the problems, the market urgently needs a clamp body convenient for firm clamping.

Most of using in clinical operation at present is ordinary right-angle pincers, directly removes to snatch the tissue through the right-angle binding clip, needs many people to cooperate at the operation in-process, and the centre gripping tissue also breaks away from easily, but along with the development of minimal access technology, the operation incision is littleer and littleer, and ordinary right-angle pincers receive the restriction in operation in-process's use. When carrying out laparoscopic surgery, sometimes some little incisions need stretch into 2 ~ 3 apparatus simultaneously and operate for the operation influences each other, can't operate smoothly. In addition, the right-angle structure of the forceps head part of the common right-angle forceps is in the same plane with the forceps body of the forceps handle and is perpendicular to the forceps handle, so that the forceps head and the forceps handle are not clearly distinguished when being overlooked, and are not easy to see under an endoscope, so that the operation can be carried out only by the feeling of an operator when blood vessels and tissues are separated, and the risk caused by blood vessel rupture or improper operation is easy to occur.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: the right-angle forceps for clamping specific tissues in the operation are provided, and the problems that the existing forceps body is inconvenient to use in clamping heavy objects, the clamped objects fall off due to insufficient clamping force easily, and the visual field is not clear in the process of performing the operation under a cavity mirror are solved.

A buckle fixed type clamp for thoracic surgery comprises a clamp body, wherein the clamp body comprises a left clamp handle, a right clamp handle, a finger ring sleeve, a clamping end head and a clamping end tail; the left forceps handle and the right forceps handle are connected through a screw or a connecting pin, and the left forceps handle and the right forceps handle are characterized in that: the clamp handle and the head of the clamping end form an angle alpha, and the head of the clamping end and the tail of the clamping end form an angle beta.

The clamping mechanism is close to the end of the clamp handle, and the clamping teeth of the clamping mechanism lock the left clamp handle and the right clamp handle.

The pliers body is made of stainless steel materials.

Clamping teeth are arranged on the periphery of the clamping end.

And the clamping teeth are provided with convex pricking points.

The protruding prick points are provided with a plurality of, and the sizes and the heights of the plurality of protruding prick points are different.

The utility model adopts the right-angle forceps which are additionally arranged at the clamping end in the prior art, the forceps handle and the head part of the clamping end form an angle alpha for better clamping tissues, the back finger ring is prevented from influencing the operation visual field, the head part and the tail part of the clamping end form an angle beta, the tip part of the forceps head can be observed, the operation visual field is wider, and the right-angle forceps for clamping specific tissues in the operation are clearer and safer during the operation. The utility model discloses a little incision operation, including the holder, the holder afterbody becomes beta angle with the holder head, become alpha angle and avoided influencing the field of vision when the operation in-process ring operation, become beta angle and guarantee the most advanced position of observation binding clip that can understand when the operation, make the operation more clear safety, can stretch into many apparatus simultaneously when satisfying little incision operation, accomplish the operation smoothly, it increases frictional force when for the centre gripping tissue to be equipped with the tong teeth, the fixed assurance of buckle formula can not drop because the object of keeping away from each other and centre gripping of holder, can not influence human tissue, make things convenient for the operation. Clamping teeth are arranged on the periphery of the clamping end. The peripheral clamping teeth can assist in supporting and lifting friction force, and stable clamping is facilitated. The clamping teeth of the clamping end are provided with convex pricking points. The raised pricks are attached to the human tissue, are particularly suitable for the human tissue with mucus, and can be firmly held. The raised pricking points are different in size and height. Realize the fixed of multiple spot multilayer point contact.

The utility model has the beneficial effects that:

1. a buckle fixed type clamp for thoracic surgery is characterized in that an alpha angle is formed between a clamp handle and the head of a clamping end, so that the operation is convenient, and the influence of a rear finger ring on the operation visual field is avoided.

2. The head of the clamping end and the tail of the clamping end form a beta angle, so that the tip part of the forceps head can be observed, the surgical view is wider, the surgical operation is clearer and safer, a plurality of instruments can be stretched into the forceps head simultaneously during the small incision surgery, the surgical operation can be smoothly completed, and mutual interference can be avoided. The utility model has the advantages of simple structure and convenient operation, ensures that the operation is smoother, improves the safety coefficient of the operation, and is particularly suitable for endoscopic operation. It is often used to clamp tissue during endoscopic surgery.

3. And the clamping mechanism is close to the clamp handle end and locks the left clamp handle and the right clamp handle. The clamping mechanism is arranged at the force application end of the clamp, so that when the clamp clamps an object, even if the force application at the finger ring is unstable, the clamping ends cannot be separated from each other, and the clamping mechanism is matched with the clamping ends for use, so that the purpose of stably clamping the object by the clamp is realized.

4. The pliers are made of stainless steel material. Clamping teeth are arranged on the periphery of the clamping end. The peripheral clamping teeth can assist in supporting and lifting friction force, and stable clamping is facilitated. The clamping teeth of the clamping end are provided with convex pricking points. The raised pricks are attached to the human tissue, are particularly suitable for the human tissue with mucus, and can be firmly held. The raised pricking points are different in size and height.
