Description

Endoscope biopsy forceps with warning texture

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an endoscope biopsy forceps with warning textures.

Background

Gastrointestinal tract examination using an endoscope for the digestive tract is becoming more and more popular. To assist diagnosis, some patients need to take a biopsy. Since biopsy is an invasive procedure, the patient may experience discomfort. In order to relieve the pain of a patient, medical staff need to quickly convey the biopsy forceps to the front end of the endoscope through a forceps channel of the endoscope, and then quickly pull out the biopsy forceps after taking part of tissues. However, the front end of the biopsy forceps is sharp, so that the speed of the biopsy forceps needs to be slowed down when the biopsy forceps reach the front end of the endoscope, and the mucosa on the inner wall of the alimentary canal of a patient is prevented from being damaged. When the forceps are pulled out too fast, the digestive tract mucosa tissue of the patient or the body fluid of the patient taken down by biopsy on the forceps can be splashed onto the body of medical care personnel, and iatrogenic infection occurs. In actual operation, it is often difficult for medical staff to know the specific length of the inserted biopsy forceps when entering the forceps, and to know the specific length of the biopsy forceps in the forceps channel when pulling the forceps, so that the inserting speed and the pulling speed of the biopsy forceps are slow, the operation time is prolonged, great discomfort is brought to patients, and the incidence rate of complications such as digestive tract mucosa injury and perforation, biopsy tissue splash, iatrogenic infection and the like is increased.

At present, the distance from the biopsy hole of the gastroscope of different brands to the front end of the gastroscope is about 120-125cm, and the distance from the biopsy hole of the enteroscope of different brands to the front end of the enteroscope is about 150-160 cm. For the same type of endoscope of the same brand, the distance from the biopsy hole to the front end of the endoscope is fixed and cannot be adjusted at will. If there is the position to get the biopsy among the endoscopy process to discover, medical personnel can move the front end of endoscope earlier to the place that needs get the biopsy, and the person of calling the cooperator inserts biopsy forceps from the biopsy hole again, reachs the front end fast, then medical personnel finely tunes the front position, and the cooperation person presss from both sides fast at last and gets quick pulling out pincers behind the biopsy tissue.

Although endoscopic biopsy forceps with a forceps-in warning mark are currently designed, there is no biopsy forceps with a forceps-out warning mark, and improvements are needed.

Disclosure of Invention

The utility model aims to provide endoscope biopsy forceps with warning textures, which enable medical staff to be prompted when the biopsy forceps are about to extend out of the front end of an endoscope or be pulled back from a forceps channel, and reduce the speed of forceps advancing or pulling at the moment, so that the operation is more accurate, the operation time is reduced, and complications and accidents can be reduced.

The purpose of the utility model is realized as follows:

the utility model provides an endoscope biopsy forceps with warning texture, includes portion of gripping, operating portion, binding clip portion and pincers body portion, the characteristic is: the pliers body outer wall and the portion close to the pliers head are provided with pliers-pulling warning textures which are rough in surface, easy to know hand feeling and used as warning marks, and the pliers-feeding warning textures which are rough in surface, easy to know hand feeling and used as warning marks are arranged on the pliers body outer wall and the portion close to the operating portion.

Preferably, the forceps-pulling warning texture and the forceps-feeding warning texture are rough uneven surfaces in different forms such as a thread shape, a concave-convex point shape and the like; the medical care personnel can easily sense the mark through fingers when holding the biopsy forceps.

Preferably, the forceps-pulling warning texture and the forceps-feeding warning texture are rough textures of 8-12 cm, so that the phenomenon that warning marks slide when the forceps are operated due to too short length is avoided.

Preferably, the distance between the texture end of the texture warning texture close to the head of the pliers and the top end of the head of the pliers is 20 cm.

Preferably, the distance between the texture end of the texture close to the side of the head of the forceps and the top end of the head of the forceps is 120cm-150cm according to whether the forceps are gastroscope biopsy forceps or enteroscope biopsy forceps.

The utility model adds the forceps-pulling warning texture and the forceps-feeding warning texture on the basis of the traditional endoscope biopsy forceps, namely, the rough warning texture with certain length is made on the outer wall of the forceps body, so that an operator can be warned when the forceps are fed and pulled only by sensing fingers when the biopsy forceps are held without switching the visual field, and the operation is very convenient without continuously switching the visual field. The utility model has the advantages that the operator can effectively provide warning for medical staff when inserting or extracting the biopsy forceps without switching the visual field, further provides basis for the medical staff to control the inserting and extracting speed of the biopsy forceps, improves the biopsy speed, reduces the biopsy time and the complication incidence rate, reduces the alimentary tract mucosa injury, the patient biopsy tissue or body fluid splash or the incidence rate of iatrogenic infection, and has simple structure and low cost.

Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

The utility model provides an endoscope biopsy forceps with warning texture, includes portion of gripping 1, operating portion 2, binding clip portion 3 and pincers body portion 6 the pincers body portion 6 outer wall, lean on binding clip portion 3 department to be equipped with the rugged surface and easily felt, as warning sign pull out pincers warning texture 4 the pincers portion 6 outer wall, lean on operating portion 2 department to be equipped with the rugged surface and easily felt, as warning sign advance pincers warning texture 5.

Preferably, the forceps-pulling warning texture 4 and the forceps-feeding warning texture 5 are rough uneven surfaces with different forms such as a thread shape, a concave-convex point shape and the like; the medical care personnel can easily sense the mark through fingers when holding the biopsy forceps.

Preferably, the length c of the forceps-pulling warning texture 4 and the length d of the forceps-feeding warning texture 5 are rough textures of 8-12 cm, so that the phenomenon that warning marks slide when in operation due to too short lengths is avoided.

Preferably, the distance a between the texture end of the pulling-out caution texture 4 close to the head portion 3 and the top end of the head portion 3 is 20 cm.

Preferably, the distance b between the texture end of the texture 5 close to the side of the head part 3 and the head part 3 is 120cm-150cm according to whether the forceps is a gastroscope biopsy forceps or an enteroscope biopsy forceps.

When the multifunctional forceps are used, a nurse holds the holding part 1 with one hand, fingers are inserted into the operating part 2, a doctor operates the endoscope with one hand, the forceps head part 3 is inserted into a biopsy hole of the endoscope with the other hand, the forceps body part 6 is rapidly pushed into the forceps body part until the forceps inlet warning texture 5 is touched, the pushing speed is slowed, and the forceps head part 3 extends out of the far end of the endoscope until the biopsy position is reached, so that the digestive tract mucosa injury and even perforation caused by too fast and too deep insertion can be effectively avoided. After the nurse finishes biopsy by operating the operation part 2, the doctor grasps the forceps body part 6 and withdraws from the biopsy forceps until touching the forceps-pulling warning texture 4, and slows down the forceps-withdrawing speed until the forceps head part 3 completely withdraws from the biopsy hole of the endoscope. Therefore, the phenomenon that digestive tract mucosa tissues or body fluids of a patient which are biopsied from the head part 3 of the forceps are splashed to the body or eyes of the operator or the user due to the fact that the forceps are pulled out too fast can be effectively avoided. Advance the overall process of pincers and pulling out pincers, medical personnel need not all remove the display screen with eyes, but just obtain the warning through the sense of touch of hand to do not influence the operation and the operation of endoscope.
