Description

Disposable endoscope living body sampling forceps

technical field

The utility model belongs to the field of medical instruments, in particular to a disposable endoscope living body sampling forceps.

Background technique

Disposable biopsy forceps are mainly used for sampling stomach, intestine, bladder, bronchi and other living tissues under clinical endoscope, and provide scientific basis for disease diagnosis through pathological tests. When the existing in vivo sampling forceps are opened, the tongs are arranged symmetrically on both sides of the tongs seat, which will affect the operator's line of sight during sampling. The tissue of the wall, and after sampling, the operator needs to keep the position of the handle and the slide block unchanged, which increases the difficulty of sampling.

Utility model content

The purpose of the utility model is to provide a disposable endoscope living body sampling forceps.

The purpose of this utility model can be realized through the following technical solutions:

A disposable endoscope living body sampling forceps, which comprises a clamp head seat, a clamp head assembly installed on the clamp head seat, a spring outer tube, a pull rod arranged in the spring outer tube, a handle and a slip ring, the clamp head seat fixed on one end of the spring outer tube, the other end of the spring outer tube is connected to the handle, the slip ring can be slidably set on the handle, and one end of the pull rod is connected to the slip ring through a rigid rod. The pliers head assembly includes a fixed pliers head, a movable pliers head and a connecting rod hinged at one end of the movable pliers head. The jaws of the movable pliers are rotatably hinged upward on the pliers seat, the other end of the connecting rod is hinged to the other end of the pull rod, and the angle between the fixed pliers and the pliers seat 10-90°. When the tongs are closed, an angle of 10-90° is formed between the tongs and the tongs seat.

The jaws of the fixed pincer head and the movable pincer head are toothed jaws.

The handle is provided with a locking piece for fixing the slip ring. The lock piece includes a row of tooth-shaped slots longitudinally arranged on the handle, a collar sleeved on the handle, and a slider arranged on the collar, the lower surface of the slider is provided with the A protrusion that matches the shape of the toothed slot.

When in use, slide the slip ring downwards along the handle to open the jaws, then slide the slip ring upwards to close the jaws to grab the biopsy tissue, fix the slip ring with a locking piece, and take out the sampling forceps.

The beneficial effects of the utility model:

The disposable endoscope living body sampling forceps of the utility model has a reasonable structure design, is convenient to use, is safe and reliable, and after the forceps head grabs the biopsy tissue, the locking state of the forceps head can be kept all the time, so as to prevent the sampling tissue from falling due to misoperation, and is convenient. operation to improve sampling efficiency. The tong head of the living body sampling forceps is located on one side of the tong head seat, and the angle of the tong head is inconsistent with the line of sight direction, which does not affect the line of sight of the operator during sampling, and can effectively forcep the tissue of the side wall of the lumen.

Detailed ways

As shown in Figure 1-2, a disposable endoscopic living body sampling forceps comprises a clamp head seat 1, a clamp head assembly mounted on the clamp head seat 1, a spring outer tube 2, and a spring outer tube 2. Pull rod 3, handle 4 and slip ring 5, the clamp head seat 1 is fixed on one end of the spring outer tube 2, the other end of the spring outer tube 2 is connected to the handle 4, and the slip ring 5 is slidable Sleeved on the handle 4, one end of the pull rod 3 is connected to the slip ring 5 through a rigid rod 13, and the pliers assembly includes a fixed pliers 7, a movable pliers 7 and one end hinged on the movable pliers 7 The connecting rod 8, the fixed pliers 6 jaws are fixedly installed on the pliers seat 1 downward, and the movable pliers 7 jaws are rotatably hinged upwards on the pliers seat 1 , the other end of the connecting rod 8 is hinged to the other end of the pull rod 3, and the angle between the fixed pliers 6 and the pliers seat 1 is 20°. When the pliers head is closed, an angle of 10-90° is formed between the pliers head and the pliers head seat 1 . The jaws of the fixed jaw 6 and the movable jaw 7 are toothed jaws.

The handle 4 is provided with a locking member for fixing the slip ring 5 . As shown in Figures 3-8, the lock includes a row of tooth-shaped slots 9 longitudinally provided on the handle 4, a collar 10 sleeved on the handle 4, and a slider arranged on the collar 11. The lower surface of the slider 11 is provided with a protrusion 12 matching the shape of the tooth-shaped slot 9 .

During use, slide the slip ring 5 downwards along the handle direction to open the jaws, then slide the slip ring 5 upwards to close the jaws to grab the biopsy tissue, fix the slip ring 5 with a locking member, and take out the sampling forceps. The working process of fixing the slip ring 5 with a lock is as follows: slide the collar 10 to a position close to the slip ring 5, and then slide the slider 11 so that the protrusion 12 on the slider 11 is clamped on the tooth-shaped clip on the handle 4. In the groove 9 (as shown in Figure 9). When the slip ring 5 needs to be moved, slide the slider in the opposite direction so that the protrusion 12 slides out of the slot 9 (as shown in FIG. 10 ).

The disposable endoscope living body sampling forceps of the utility model has a reasonable structure design, is convenient to use, is safe and reliable, and after the forceps head grabs the biopsy tissue, the locking state of the forceps head can be kept all the time, so as to prevent the sampling tissue from falling due to misoperation, and is convenient. operation to improve sampling efficiency. In addition, the tong head of the biopsy forceps is located on one side of the tong head seat 1, and the angle of the tong head is not consistent with the line of sight direction, which will not affect the line of sight of the operator during sampling, and can effectively clamp the tissue of the side wall of the lumen.
