Description

Flat mouth clip applier

Technical Field

The utility model relates to a medical instrument, in particular to a flat mouth clip applier.

Background

Once a focus is found in a human body cavity, if excision is needed, researches show that endoscopic minimally invasive surgery is promoted more and more, the wound is small, and the occurrence of infection can be reduced.

Research shows that in the process of endoscopic surgery, a large amount of bleeding occurs due to rupture of blood vessels or a bile duct and other thin ducts need to be cut off and clamped, in the prior art, electric coagulation is carried out on bleeding parts in a human body by using electric coagulation forceps, so that the internal bleeding parts are coagulated and stopped bleeding, or methods such as suturing and the like are used, and the defects that firstly, the wound of a patient is healed slowly, and the wound healing effect is worse if the patient is weak; secondly, the suture operation time is long, and the ideal operation effect cannot be met.

Some surgical clip appliers are matched with a contraction ligation clip to close blood vessels or tissues in the market, so that the problems can be solved, and the defects that the surgical clip appliers are difficult to find and easy to slip when pressing a clip foot in the clinical use process, and the absorbable clip can be excited under the condition that the absorbable clip is not firmly installed, so that the outer sleeve of the absorbable clip falls off and the body cavity is left.

Some researchers have tried to design a structure of ear protector on the clip, which solves the problem of stability, but has difficulty in complex installation and removal, but the requirement of rapid hemostasis in the operation, easy installation and removal is not met. Therefore, at present, no clear and effective method is available for solving the problems of quick installation and use, easy disassembly and difficult retention in the body cavity.

Disclosure of Invention

An object of the utility model is to provide a flat mouth pincers of executing, this pincers prevent in laparoscopic surgery that the ligature presss from both sides and receives by closed tissue and blood vessel effort or hang and wipe and drop, safer carries out effective closure to human internal blood vessel or tissue.

The technical scheme of the utility model is that: a flat mouth clamp comprises a clamp rod, a handle, a tail cap and a thimble; the clamping forceps rod is arranged on the handle, a tail cap is arranged at the tail end of the handle, a thimble penetrates through the clamping forceps rod, the head end of the clamping forceps rod is a flat opening, a clamping foot is respectively arranged at the parallel incision side in the flat opening, the clamping feet are of a rectangular plane structure, and the specifications of the two sides are consistent; the mounting end of the absorbable forceps is matched with the head end of the clip applier rod, and the absorbable forceps are movably inserted into the head end of the clip applier rod.

The spring is arranged in the middle of the rectangular plane, and the bayonet is arranged at the top end of the rectangular plane.

The rotator is sleeved on the clamping applying clamp rod through a rotating ring, and the rotator rotates by 360 degrees infinitely.

The rectangular top bayonet is in a shape of a rat tooth protruding inwards.

The 1/2 position on the rectangular plane is provided with horizontal stripes.

The utility model has the advantages that: the clamping feet at the cut side of the rod head end of the clamping forceps are of a rectangular plane structure, a spring is arranged in the middle of the rectangular plane, a mouse-tooth-shaped bayonet is arranged at the top end of the rectangular plane, white paint is coated on the clamping feet, and 1/2 transverse stripes are formed on the rectangular plane of the clamping feet. In clinical use, the clip is convenient to find the clip foot quickly, is not easy to slip when pressed and can absorb the clip to enhance the firmness. The problem that the original clip applier is not easy to find and slip when pressing the clip feet is solved, and the clip applier can be normally excited when not correctly putting the absorbable clip in the groove is solved. With this improvement, the surgical compliance is improved and the risk of foreign body remaining in the body during surgery is reduced.
