Description

Adjustable equipment of annex business turn over length in cooperation pincers way

Technical Field

The utility model belongs to the technical field of auxiliary equipment of medical instruments, and particularly relates to adjustable equipment matched with an accessory in a clamp channel to adjust the in-out length.

Background

At present, when medical care personnel carry out enteroscopy treatment (three-fourth-level operations such as EMR, CSP, ESD and the like), the cooperation of a left hand and a right hand and the cooperation of a nurse are needed. The method specifically comprises the following steps: the left hand of the doctor controls the handle part and is responsible for a big-small button (generally, a left thumb controls the up-down and left-right directions of the front lens through the up-down rotation of the big-small button), a fixed picture, a switching mode, air supply, water supply and suction (generally, the operation is finished by an index finger, a middle finger and a ring finger, but some people rarely use the ring finger but the little finger cannot be used by all people according to personal habits).

The physician's right hand is responsible for holding the scope, inserting the mirror into the stomach or intestine, and keeping its position fixed (often with some rotation, displacement, etc. of the scope in the fixed state, which also affects the position of the lesion in the field of view, and thus designs that involve purely fixing the scope are also deficient in this respect).

Currently, when performing an operation, doctors, left and right hands and nurses are responsible for each task, so clinically, the control of the access of accessories, snares and various knives for ESD (collectively referred to as accessories) is a difficult point to be solved urgently (including biopsy forceps, hemostatic forceps and the like in examination), and the existing main solutions and defects are:

1. the nurse assists, but the operation of the nurse (i.e. the control of the snare opening and closing, the tool bit entering and exiting, etc.) is influenced to a certain extent, and the entering and exiting time, the entering and exiting distance, the entering and exiting speed, etc. can not completely meet the requirements of doctors.

2. The right hand of the doctor leaves the endoscope body, and the right hand controls the accessory to go in and out. However, since the lens body is not in a free state, a slight movement can have a large effect on the front lens and the diseased site, and the breathing movement of the patient can also have an effect on the lens body, so that the design of simply fixing the lens body is still deficient in this respect.

3. The right hand of the doctor leaves the endoscope body, and the right hand controls the accessory to go in and out. In addition, a separate nurse is equipped to hold the endoscope body, but on one hand, manpower and material resources are increased, and on the other hand, the control of the nurse holding the endoscope body on the endoscope body can not completely meet the requirements of doctors.

4. The doctor fixes handle portion in the front of the chest with the left wrist, controls annex business turn over with the thumb of left hand and forefinger, but the operation is inconvenient, and leaves big button after the left hand, can produce the influence to front end camera lens and pathological change position (under the pathological change position fixed state in the field of vision, big button often is not in free state).

5. The doctor clamps the accessories through the ring finger and the little finger of the left hand to control the in and out of the medical apparatus, but the operation is very inconvenient and the requirement on the operator is high.

6. The doctor can control the entrance and exit of the left hand by clamping the accessory with the index finger and the middle finger or the middle finger and the ring finger of the left hand, but the operation is very inconvenient and the requirement on the operator is high.

As an improvement, each group of meshing blocks comprises meshing tooth-shaped structures, wherein the two groups of meshing tooth-shaped structures are oppositely meshed and arranged, and the two groups of meshing positions are clamped with a distribution line of an accessory at the inlet end of a clamp channel.

As an improvement, the meshing part comprises a meshing cylinder, a cushion block and a stop part; the rodent cylinder is of a cylinder structure with a side hole on one side wall; the cushion block is fixedly arranged on the inner side wall of one side, which is just opposite to the side hole of the rodent barrel; the stop part is movably inserted into the side hole of the rodent barrel and used for enabling the distribution line to abut against the cushion block for fixing.

As an improvement, when the adjustable equipment is initially clamped with the distribution line, the distance from the clamp channel inlet port is 2-10cm, and the distance from the front end of the distribution line to the outlet end of the distribution pipeline is +/-1 cm.

As a modification, the inner diameter of the pull ring is set to be 14-18mm, and the biting inner diameter of the biting part is not more than the diameter of the dispensing line.

Has the advantages that: the utility model provides equipment, which can put fingers of doctors and further can put small finger sleeves into finger rings, and the finger rings drive the equipment structure to move up and down to control accessories (a snare, various ESD knives and the like) conveyed by a delivery line, so as to carry out operations such as time, distance, speed and the like of entering and exiting. Compared with the existing equipment, the device has the following effects:

(1) the little finger of the left hand is fully utilized to control the in and out of the accessory, so that the manpower resource is saved, and the clinical requirement can be met.

(2) The control of the accessory (including the timing, the distance and the speed of the accessory) can be refined, the cost is low, the operation is simple, and the requirement on doctors is not high, so that the operation time can be shortened, the occurrence of complications can be reduced, and the method is suitable for large-scale clinical popularization and application.
