Description

Combined stripper

Technical Field

The utility model relates to a chopsticks formula is peeled off, specifically is a combination form peel off, belongs to medical instrument technical field.

Background

The micro-dissector is one of the common instruments used in neurosurgery, is flexible to operate and slightly sharp, and is generally used for separating deep interfaces, such as the interface between nerve and tumor or the adhesion between nerve and blood vessel. The microseeler originates from the west and is operated in a one-handed grip, while the other hand needs to be engaged by a suction or other instrument, in a two-handed operation similar to the knife and fork engagement used for western diets.

The common nerve dissector used at present is usually made of a slender flat metal rod and a sharp dissecting head, veins are easy to bleed in the process of neurosurgery, the dissector can only retract a certain point on the nerve or dura mater when in use, the retracting operation space is very narrow and limited, the visibility is poor during the operation, and the operation is difficult. The efficiency of the operation is reduced, and nerve damage is also easily caused.

In addition, medical staff usually use forceps to perform the function of grasping blood vessels, tissues, and the like, and cannot perform the function of grasping by a simple detacher.

Preferably, the handheld part is a cuboid with round corners, and the cross section of the handheld part is a square with round corners.

Preferably, the ratio of the diameter of the operation portion to the diameter of the hand-held portion is 1: 2.5 to 3.

Preferably, the diameter of the rod-shaped operating part can be 1-3 mm, and the diameter of the handheld part can be 4-6 mm.

Preferably, the stripper is made of stainless steel.

Has the advantages that:

the utility model discloses increased the grip function who peels off the son, the effective cooperation of two strippers of one-hand operation simultaneously can more effectual separation tissue, is the effective improvement to current stripper, has richened micro neurosurgery's operation mode.

Meanwhile, the operation mode accords with the operation habit of Chinese people, is easy to operate, can increase the fineness of the operation and can shorten the operation time.

Chopsticks, on the other hand, are elongated sticks held in the fingers to pick up food or other things, and are similar in general form to the strippers used in surgery. Considering that Chinese people use chopsticks from their own young, the inventor believes that Chinese people can perform fine operation by operating 2 strippers with one hand very easily.

2 strippers are made into a combined instrument, so that the fine operations of micro neurosurgery such as stripping, clamping, retracting and the like can be completed by a neurosurgeon with one hand, when the utility model is used, the clamping function of the strippers is more labor-saving than that of the traditional tweezers by utilizing the lever principle, the strippers are more flexible to use, and the operations of various angles can be realized according to the needs of the surgeons in a narrow space; the utility model has the advantages of the function that one can also realize conventional stripper of exclusive use, need realize the function of centre gripping, retractor, use two strippers again, can use in a flexible way according to operation doctor's needs, need not to replace surgical instruments, convenient to use.

The inner side surface of the head part is two tangent planes which are mutually matched, so that the head part can be well matched and has certain clamping force when in use. The outer side surface of the head is of a hemispherical or quasi-hemispherical structure, so that blood vessels, nerves and other tissues can be well separated. Meanwhile, the operation part of the stripper is improved, so that the thickness degree of the operation part is more beneficial to the chopstick type operation by one hand.

Through the improved design, the soft tissue closely related to the nerve tissue in the narrow area can be separated and incised more efficiently, and the operation safety is improved.

The handheld portion is the cuboid that has the chamfer, and the cross section is the square that has the chamfer to the medial surface of the handheld portion of handheld portion still is equipped with magnetic material, and the medial surface that two operation portions are relative can laminate each other through magnetic material, and the arrangement of being convenient for is deposited.
