Description

Wide-angle biopsy forceps for gastroscope

technical field

The utility model relates to the technical field of medical instruments, in particular to a wide-angle biopsy forceps for gastroscopy.

Background technique

For the diagnosis of patients with stomach disease, biopsy forceps are usually used for sampling inspection to determine the pathological nature. The existing biopsy forceps are difficult to control the bending direction and angle of the forceps head, and the forceps body is mostly parallel to the diseased tissue. When taking samples from small and curved parts of the body, traditional biopsy forceps rotate themselves without bending samples, which affects diagnosis and is inconvenient to operate.

Utility model content

The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art, and provide a wide-angle biopsy forceps for gastroscopy. Sampling, simple operation, convenient and practical.

In order to solve the existing problems of the background technology, the utility model adopts the following technical solutions:

A wide-angle biopsy forceps for gastroscopy, which includes a biopsy forceps body, a forceps mouth push-pull rod, a cable, a flexible catheter, a manipulated bending head and a forceps mouth, the left side of the biopsy forceps body is sleeved with a forceps mouth push-pull rod , the push-pull rod of the pliers mouth is connected with the pliers mouth through a pull cable, and it also includes a bending and rotating operation wheel of the pliers head, an operating rope and a 180-degree rotating disk. The side is connected to the 180-degree rotating disc through a flexible conduit, and the right side of the 180-degree rotating disc is connected to the manipulated bending head. The manipulated bending head is provided with a pliers mouth, and the manipulation rope runs through the flexible conduit to connect the pliers head to bend the rotating operation wheel and 180 degrees. spinning disk. Manually rotate the forceps head to bend and rotate the operation wheel to drive the movement of the control rope, and the rotating disc rotates slowly under the drive of the control rope, so that the jaws of the forceps bend and cut the diseased tissue of the inner gastric wall.

Preferably, the pliers mouth and the manipulated bending head are movably connected.

As a preference, the bending and rotating operation wheel of the pliers head can rotate 360 degrees.

As a preference, the inner diameter of the bending and rotating operation wheel of the clamp head is larger than the inner diameter of the 180-degree rotating disk, and the large wheel drives the small wheel through the operating rope, which is easy to operate, convenient and practical.

The working principle of the utility model: when sampling the stomach wall, first extend the mouth of the biopsy forceps and the soft catheter from the esophagus into the stomach, then look for pathological tissues through the endoscope, and then manually rotate the forceps head to bend and rotate the operation wheel to drive the control rope Movement, the rotating disc rotates slowly under the drive of the control rope, so that the jaws of the forceps are bent, and the diseased tissue of the inner gastric wall is cut.

Compared with the prior art, the utility model has the advantages of simple structure, the bending of the jaws can be controlled by bending and rotating the operation wheel of the jaws, and sampling of the stomach wall or esophageal bend is simple, convenient and practical.

Description of drawings

Below by embodiment, the utility model is further described in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the utility model;

1 is the body of the biopsy forceps, 2 is the push-pull rod of the jaw, 3 is the cable, 4 is the soft catheter, 5 is the bent head to be manipulated, 6 is the jaw, 7 is the bending and rotating operation wheel of the jaw, 8 is the control rope, 9 is a 180 degree rotating disk.

Detailed ways

As shown in Figure 1, a kind of wide-angle biopsy forceps for gastroscope, it comprises biopsy forceps main body 1, forceps mouth push-pull rod 2, drag wire 3, soft catheter 4, manipulated bending head 5 and forceps mouth 6, described biopsy forceps The left side of the pliers body 1 is sleeved with a pliers mouth push-pull rod 2, the pliers mouth push-pull rod 2 is connected to the pliers mouth 6 through a cable 3, and it also includes a pliers head bending and rotating operation wheel 7, a control rope 8 and a 180-degree rotating disk 9 , the middle of the biopsy forceps body 1 is provided with a forceps head bending and rotating operation wheel 7, the right side of the biopsy forceps body 1 is connected to a 180-degree rotating disk 9 through a flexible catheter 4, and the right side of the 180-degree rotating disk 9 is connected to a manipulated bending head 5. The controlled bending head 5 is provided with a pliers mouth 6, and the operating rope 8 runs through the flexible conduit 4 to connect the pliers head bending rotating operation wheel 7 and the 180-degree rotating disk 9. The pliers mouth 6 and the manipulated bending head 5 are movably connected. The bending and rotating operation wheel 7 of the pincer head can rotate 360 degrees; the inner diameter of the bending and rotating operating wheel 7 of the pincer head is greater than the inner diameter of the 180 degree rotating disk 9, and the big wheel drives the small wheel through the control rope, which is simple to operate, convenient and practical.

When sampling the stomach wall, first extend the forceps mouth 6 and the flexible catheter 4 from the esophagus into the stomach, then look for pathological tissues through the endoscope, and then manually rotate the forceps head to bend and rotate the operation wheel 7 to drive the operation rope 8 to move, 180 The rotating disk 9 rotates slowly under the drive of the control rope 8, so that the jaws 6 of the forceps are bent, and the pathological tissue of the inner gastric wall is sheared.

The above-described embodiment is only an example of the utility model, and is not used to limit the implementation and scope of rights of the utility model. All technical solutions that are identical or equivalent to the claims of the utility model should be included in the utility model. within the scope of protection.
