Technical Field

The utility model relates to the technical field of medical instruments, in particular to an intracavity separated atraumatic great vessel blocking clamp.

Background

The large blood vessel blocking clamp in the cavity is mainly used for blocking a large blood vessel (such as a lower vena cava) in robot and laparoscopic cavity operations, has no damage to the blood vessel wall or only temporary slight damage, has good blood flow blocking performance, has different types, and can select proper blood vessel blocking clamps according to the wound position, the blood vessel caliber, the blood flow pressure and the like of the blood vessel to be blocked. When a patient suffering from renal cancer with an inferior vena cava tumor embolus is subjected to an inferior vena cava tumor embolus removing operation, a blood vessel blocking clamp is often required to firmly clamp the vena cava to block blood flow, and then an intravascular tumor embolus is removed. In open surgery, the great vessels are blocked by atraumatic vessel forceps or lateral wall forceps. At present, an integrated blood vessel blocking forceps is used for blocking a large blood vessel in a robot and laparoscopic surgery, but the blood vessel blocking forceps cannot be placed in a body through a cannula required by a conventional surgery, and an additional operating cannula is required, thereby increasing the trauma of the surgery and the complexity of the surgery.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing an intracavity-separated atraumatic great vessel occlusion clip, which can smoothly enter an inner cavity of a surgical site of a patient, controls a handle of the vessel occlusion clip and enables a chuck to open to clamp a great vessel by conventional instruments such as a clip holder, a robot or a laparoscope, and has the characteristics of simple structure, smooth outer surface, convenient operation and good vessel occlusion effect.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: an intracavity separated atraumatic great vessel occlusion clip comprises a front forceps holder and a rear forceps holder which are symmetrically arranged; the front forceps holder and the rear forceps holder are overlapped in a crossed mode in the middle, bent clamping heads which face forwards symmetrically are arranged at the left end portion of each front forceps holder and the left end portion of each rear forceps holder, a connecting area is arranged at a handle at the right end of each front forceps holder and the right end of each rear forceps holder to form a forceps holder whole, symmetrically distributed stress points which are clamped by a forceps holder or a conventional surgical instrument are arranged on the outer side face of the middle portion of each front forceps holder and the outer side face of the middle portion of each rear forceps holder respectively, two stress points which correspond to each other in an up-down mode are a pair, and the shape of each pair of stress points is identical and is matched with the shape of the clamping heads of the forceps holder or the conventional surgical instrument.

The intracavity separation type atraumatic great vessel occlusion clamp is characterized in that the number of the stress points is multiple.

The intracavity-separating type atraumatic great vessel occlusion clamp is characterized in that the stress points are two pairs, one pair on the left side is a quadrangular frustum pyramid clamping stress point, the other pair on the right side is a notch clamping stress point, and a distance is kept between the quadrangular frustum pyramid clamping stress point and the notch clamping stress point.

The intracavity separation type atraumatic great vessel occlusion clamp is characterized in that the connecting area is a bending connecting area.

The intracavity separation type atraumatic great vessel occlusion clamp is characterized in that the connecting area is fixed by rivets.

According to the intracavity separated type atraumatic great vessel occlusion clamp, the left inner side surfaces of the front clamp and the rear clamp are respectively provided with atraumatic insections, and the whole clamps are polished to form a smooth surface.

The utility model provides an intracavity separated atraumatic great vessel occlusion clamp, which comprises a front clamp and a rear clamp which are symmetrically arranged; the front forceps holder and the rear forceps holder are overlapped in the middle in a crossed mode, bent clamping heads which face forwards symmetrically are arranged at the left end portion of the front forceps holder and the rear forceps holder, a connecting area is arranged at the handle at the right end of the front forceps holder and the handle at the right end of the rear forceps holder to form the forceps holder whole, stress points which are symmetrically distributed and clamped by a conventional surgical instrument are arranged on the outer side face of the middle portion of the front forceps holder and the outer side face of the middle portion of the rear forceps holder respectively, the two stress points which correspond to each other in the vertical direction are a pair, and the shape of each pair of stress points is the same and is matched with the shape of the clamping heads of the conventional surgical instrument. The blood vessel blocking clamp enables the front clamp and the rear clamp to generate elastic clamping force under the action of the connecting area, and a doctor uses the front end of the needle holder for conventional operation to apply clamping force to a stress point on the outer side surface, so as to control the bending chuck to open and clamp a large blood vessel. The vascular occlusion clip was removed post-operatively in the same manner. The beneficial technical effects of the utility model are as follows: can be used repeatedly, can conveniently and quickly cooperate with a surgeon to complete the great vessel occlusion, helps the surgery to be smoothly carried out, and has the characteristics of simple structure, convenient operation and control and improved medical operation efficiency.
