Abstract

The utility model relates to a dual-purpose nerve root draw hook. The utility model overcomes the problems that the blood in the operating field additionally needs an aspirator to be sucked because the existing nerve root draw hook is solid, and therefore, the instruments are multiple, the operating field is influenced, and the operation is inconvenient. The utility model is characterized in that a draw hook which is bent into a right angle is arranged in the utility model, and the top end of the draw hook is processed into an oblate shape; a through hole is arranged from the center of the top end of the draw hook to the center of the tail end of the draw hook; the upper wall at the nook of the right angle which the draw hook is bent into is provided with a regulating hole which is communicated with the center through hole of the draw hook. At the operation time, the blood in the operating field can be sucked from the central through hole of the draw hook. Therefore, the operation becomes convenient, the field of vision in the operation becomes clear, the operation time is shortened, and the occurrence of the side damage can be efficiently prevented.

Description

Dual-purpose nerve root pulling hook

This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of dual-purpose nerve root retractor.

Surgery is done operation in the canalis spinalis now, needs with nerve root retractor nerve root to be pulled to a side, and existing nerve root retractor is the steel solid, and promptly cross section is an entity, and the blood of art Yezhong needs to attract with suction pump in addition.Because apparatus is many, the art open country is little, influences the visual field, and it is very inconvenient to perform the operation, and also correspondingly can prolong operating time and dangerous, causes secondary damage easily.

The purpose of this utility model is single nerve root retractor is made its dual-use function with drag hook and suction catheter after improving, and the quantity of apparatus makes clear visual field, facilitating operation, safety when performing the operation to reduce.

This utility model is to realize like this, it have one curve 90 degree, the top is processed into the drag hook of oblate shape hook, there is a through hole at center from the drag hook top to tail end, curves an angle of 90 degrees corner upper wall at drag hook and also is processed with an adjustment hole that communicates with the drag hook central through hole.During operation, with drag hook nerve root is pulled to a side, draw the tail end of structure to connect medical suction pump sebific duct, the blood of art Yezhong can attract by the central through hole of drag hook, thereby has made things convenient for operation.

Advantage of the present utility model is simple in structure, and is easy to use, and the visual field is clearer in the operation, can shorten operating time, prevents the generation of secondary damage effectively.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is this utility model structural representation;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is an axonometric drawing of the present utility model.

As shown in drawings: this utility model has a drag hook 1 of making of copper or rustless steel, and oblate shape hook 4 is processed on the top of drag hook 1, and (upper end is square to the cross section of drag hook 1, so that operation; The lower end is circular, so that in human body, rotate and prevent to touch hurt sb.'s feelings nerve or spinal cord in the body) to be processed with that a through hole 2(also can adopt be square tube at the center, be processed into drag hook for pipe through the mode of welding forming down), on curving the corner upper tube wall of an angle of 90 degrees, drag hook 1 has an adjustment hole 3 that communicates with through hole 2 in the drag hook 1, adjustment hole 3 is regulated the size of openings of sizes with the adjustable pipe inner suction at the Shi Keyong finger of performing an operation, when drag hook 1 inner via hole 2 is blocked or when cleaning through hole 2 in this drag hook 1, adjustment hole 3 can also make things convenient for stretching into to make things convenient for cleaning of poker.

Claims

1, a kind of medical apparatus and instruments, be particularly related to a kind of dual-purpose nerve hook, comprise one curve 90 °, the top is processed into the drag hook 1 of oblate shape hook, it is characterized in that: drag hook 1 has a through hole 2 to the center of tail from the top, curves 90 ° of corner upper walls at drag hook 1 and also is processed with an adjustment hole 3 that communicates with through hole 2 in the drag hook 1.
