Description

Biopsy forceps convenient to operate

Technical Field

The utility model relates to a biopsy forceps with convenient operation, which belongs to the technical field of medical appliances.

Background

At present, biopsy sampling, testing and analysis are often required to be carried out on suspicious lesions in the process of amplifying gastroscopy, which is beneficial to the diagnosis of disease conditions. Like chinese utility model patent document (patent number is 201420224613.9, the grant announcement day is 2014 09 months 24 days) show, current biopsy forceps generally comprises core bar, sliding ring (being equivalent to the sliding handle), sleeve pipe (being equivalent to the spring tube) etc. during the operation, only need the ring of the fixed core bar afterbody of thumb, forefinger and middle finger press from both sides tight fixed sliding ring, it pushes away the sliding ring to go forward, utilize the cable to make the forceps holder open, make the forceps holder aim at and need get biopsy department, pull the sliding ring after, make the forceps holder close through the cable, the forceps holder presss from both sides tightly to sting and cuts off the tissue. However, the slip ring of the biopsy forceps with the structure is relatively easy to move relative to the core bar, so that the opening and closing of the forceps head are not convenient to control, and inconvenience is brought to the sampling process.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the defects of the prior art and provides a biopsy forceps convenient to operate.

The technical scheme of the utility model as follows:

a biopsy forceps convenient to operate is characterized in that a handle of the biopsy forceps comprises a core bar fixedly connected with a sleeve and a sliding ring sleeved on the core bar and fixedly connected with a pull rope, wherein a first limiting locking mechanism is arranged at one end, close to a forceps head, of the core bar; the first limiting locking mechanism comprises a first limiting plate, a first limiting ring and a first spring, wherein the first limiting plate is fixed on the outer wall of the core rod, the first limiting ring and the first spring are sleeved on the core rod, and the first limiting ring is in threaded connection with the core rod; the first spring is arranged between the first limiting ring and the first limiting plate, one end of the first limiting ring is in contact with the first spring, and the other end of the first limiting ring faces the front end of the sliding ring.

Preferably, the core rod is provided with scale marks.

Preferably, one end of the core rod, which is far away from the binding clip, is provided with a second limiting and locking mechanism; the second limiting locking mechanism comprises a second limiting plate, a second limiting ring and a second spring, wherein the second limiting plate is fixed on the outer wall of the core rod, the second limiting ring and the second spring are sleeved on the core rod, and the second limiting ring is in threaded connection with the core rod; the second spring is arranged between the second limiting ring and the second limiting plate, one end of the second limiting ring is in contact with the second spring, and the other end of the second limiting ring faces the rear end of the slip ring.

When the utility model does not need to take a sample, the first limiting ring can be twisted to move away from the first binding clip, the sliding ring is pushed, the first binding clip is in a closed state, and the first spring can further compress and stabilize the first limiting ring; when a sample needs to be taken, the first limiting ring is screwed towards the direction of the clamp head, so that the first limiting ring is not contacted with the sliding ring, and at the moment, the sliding ring is not limited in movement and can be normally used. Similarly, in order to further stabilize the slip ring, a second limiting locking mechanism can be arranged at the other end of the core rod, and the using method is the same as that of the first limiting locking mechanism. If not when taking a sample, usable two spacing rings lock the location to the sliding ring, if after the sample, usable two spacing rings lock the location to the sliding ring, make the binding clip keep pressing from both sides tight closed state, can convenient to use person vacate both hands and do other relevant work.

The utility model has the advantages of simple and reasonable structure, the manufacturing is easy, can lock, relax the sliding ring, provides convenience for biopsy sampling work, has wide market space.
