Description

A biological clip applier with rotatable head

technical field

The utility model relates to the technical field of medical equipment, in particular to a rotatable biological clamp applicator.

Background technique

In minimally invasive laparoscopic human surgery, there are single-hole operating channels and multi-hole operating channels. The single-hole combined operating channel is to cut a 3-4 cm incision in the abdominal cavity of the human body, and the combined operating channel of the single-hole entrance is inserted into the incision. , the surgical instrument enters the abdominal cavity of the human body through the combined operating channel. However, due to the intricate blood vessels distributed in the human body, blood vessels need to be clamped with vascular clips and clip appliers; however, the blood vessels are intricate and have different angles, and the surgical incision is small. The head of the traditional biological clip applier is generally It is straight, and when operating under a laparoscope, it is often due to the angle problem between the laparoscope and the clip applier (because both the laparoscope and the clip applier enter from the surgical incision, but the angle is deviated, the existing applicator When the clip is illuminated by the laparoscope, the clip applier cannot be operated; when the clip applier can be operated, the laparoscope is inconvenient to use) and the angle between the position of the blood vessel and the clip applier makes it difficult to operate the clip applier. Reduced operation efficiency and prolong operation time.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art, to provide a biological clip applicator with a reversible head, which can be combined with an elbow pliers rod to form a biological clip applicator according to the needs, so as to solve the existing Under the endoscope, the clamp is inconvenient to clamp due to the angle, and its structure is simple, convenient and practical.

In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the utility model is realized through the following technical solutions:

A rotatable biological clip applier, comprising a clamp rod, a clamp head, a fixed handle, a movable handle and a control rod, the control rod is connected with the movable handle and the fixed handle in the clamp rod, and the clamp rod is connected with the clamp An elbow pliers rod is arranged between the heads, and the elbow pliers rods are provided with 15°, 30°, 45° elbow pliers rods according to the bending angle. The rod and the tong head are connected through an elbow tong rod rod, and the elbow tong rod and the elbow tong rod are firmly connected to the tong rod and the control rod through threads, and a bending angle mark is provided on the elbow tong rod.

Preferably, the pliers rod and the elbow pliers rod are connected by threads, the elbow pliers rod and the elbow pliers rod are provided with internal threads, and the pliers rod and the control rod are provided with external threads fully matched therewith.

Preferably, a rotatable knob is provided at the end of the pliers rod connected to the fixed handle and the movable handle.

The beneficial effects of the utility model are: the utility model can turn the head of the biological clip applicator, and the elbow pliers rod can be selected according to the needs to be combined into the biological clip applicator, which solves the problem of the existing clip applier under endoscopy due to abdominal cavity The problem of the angle between the mirror and the clip applier and the angle between the position of the blood vessel and the clip applier can make the clip applier difficult to operate, which improves the operation efficiency, is convenient and practical; and can be used in other minimally invasive Surgical use.

Of course, any product implementing the present utility model does not necessarily need to achieve all the above-mentioned advantages at the same time.
