Abstract

An adjustable multifunctional spine draw hook solves the problems of the conventional spine draw hook, such as single draw point and unsatisfactory draw effect. The adjustable multifunctional spine draw hook comprises support pliers and a draw hook; the support pliers comprises two pliers handles hinged with each other, wherein a ratchet piece is mounted on one pliers handle and a ratchet pawl is mounted on the other pliers handle; and the draw hook comprises a curved plate and a handle, wherein the draw hook is mounted in draw hook mounting holes at the front ends of the pliers handles. The draw hook is characterized in that a foldable-type link rod is mounted at the front end of each pliers handle, and a draw hook is also mounted at the front end of each foldable-type link rod. The utility model has the advantages that the foldable-type link rods and the support pliers can be combined randomly to realize multi-point drawing; and the depth of the draw hooks, as well as the open angle of the support pliers, can also be freely adjusted through a fixed-drawing trough on the draw hook handle and the foldable-type link rods, thereby achieving good drawing effect, more clearly exposing operation area, bringing great convenience to a doctor, reducing operation personnel, and lowering work intensity of operation of medical staff.

Description

Adjustable multifunctional spinal column drag hook

Technical field

This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of adjustable multifunctional spinal column drag hook.

Background technology

In cervical vertebra, lumbar vertebra and thoracic vertebra operation, need muscular tissue be pushed aside with the spinal column drag hook, field of operation is come out, so that undergo surgery.The shape of existing spinal column drag hook is as a pair of tongs, it is made of support clamp and two drag hooks, handle is hinged forms by two pincers for support clamp, drag hook is board-like drag hook or comb-tooth-type drag hook, drag hook is installed in the installing hole of pincers handle front end, on a pincers handle, the ratchet sheet is installed, on another pincers handle, ratchet is installed, prevent that drag hook from strutting the back retraction.The subject matter that this spinal column drag hook exists is, because spinal column exists physiological bending, the articular process of neck, breast, lumbar vertebra has nothing in common with each other again, and cervical vertebra is low flat, lumbar vertebra processus aboralis and again can hypertrophy cohesion, transverse process of thoracic vertebra is higher than articular process, so, spinal column rear and the non-straight seen in the art Yezhong, and existing spinal column drag hook can not make field of operation reach satisfied appearing, a position stops that then deep tissues can't retract, and drag hook can not up-down adjustment, brings certain difficulty to operation.In addition, have only a pair of drag hook on the support clamp, when field of operation than long time, also need in addition tractive of the hand-held drag hook of medical worker, the medical worker that operation needs is more, and operation intensity is big.

Summary of the invention

The technical problems to be solved in the utility model is, overcomes single, the unfavorable problem of tractive effect in traction point that existing spinal column drag hook exists, and a kind of multiple spot tractive, the depth is adjustable, tractive is effective adjustable multifunctional spinal column drag hook are provided.

This utility model comprises support clamp and drag hook, handle is hinged forms by two pincers for support clamp, on a pincers handle, the ratchet sheet is installed, on another pincers handle, ratchet is installed, drag hook is made of bent plate and handle, and drag hook is installed in the drag hook installing hole of pincers handle front end, and its special character is, front end at the pincers handle is equipped with collapsible connecting rod, at the front end of collapsible connecting rod drag hook is installed also.

On the handle of drag hook, there are several to decide kerve, so that regulate the depth position of drag hook.

The base of the bent plate of drag hook is linear, zigzag, little circular arc, great circle arc, two fork-shaped, flat arc or asymmetry, to adapt to different vertebras.

On the bent plate of drag hook, also has relief hole, to reduce pressure to tissue.

Advantage of the present utility model is, but collapsible connecting rod and support clamp arbitrary combination, realize the multiple spot tractive, utilize on the drag hook handle decide kerve and collapsible connecting rod can also arbitrarily be adjusted the depth of drag hook, but and the open angle of regulated at will support clamp, tractive is effective, make the more clear of field of operation exposure, for the patient provides bigger convenience, also can reduce surgical staff, reduce the working strength of medical worker's operation.
