Description

Novel adjustable exposure of surgical field drag hook

Technical field

The utility model is related to a kind of Medical treatment device rings.More particularly to incidence and superficial hook for surgery operation are used for.

Background technology

Majority hook for surgery operation is both needed to manual operation at present, and appearing well at least needs two to three assistants, especially in incidence It is crowded when operation, operator doctor operation may be influenced, and the shortcomings of there are durable force differences.And existing self-retractor is used to The big visual area such as abdominal cavity, pelvic cavity, size is big, cannot be used for neck and superficial operation, only a kind of for device for endoscopic thyroid hand The drag hook of art is invasive design, and operating process is more complex.Existing drag hook manufacture craft, material requirements are high, and somewhat expensive is protected Support, safeguard it is more difficult, most middle and small hospital application and popularizations are difficult.So urgent clinical needs one kind is more convenient, effectively novel drawing Hook.

The existing adjustable retractor used that designs works well, but because reasons in structure has certain deficiency.Has drag hook body portion Still it is the extension of multijaw structure, it is apparent finds that the design squeezes skin subcutaneous tissue in actual use, especially in the long period It may cause tissue compression extravasated blood after traction, ecchymosis is subcutaneously presented, influence wound healing and beauty.

Invention content

The purpose of this utility model is to provide a kind of novel adjustable exposure of surgical field drag hook, to solve because to subcutaneous group of skin It is apparent to knit extruding, especially may cause tissue compression extravasated blood after the long period draws, ecchymosis is subcutaneously presented, influence wound healing And the technical problems such as beauty.

In order to achieve the above-mentioned object of the invention, the utility model adopts the following technical scheme that：

Novel adjustable exposure of surgical field drag hook, including front drag hook part and rear traction element；Front drag hook portion It is in plane to be divided into back segment, and the arc-shaped plates of leading portion are monodactyle or multijaw structure at the front end of the arch section of plates, These pawl laid out in parallel, in the identical radian for adapting to different depth level drawings and needing, pawl point is passivity structure；The rear Traction element includes being set with the tail portion of the shank of the angled connection of plane where the tail portion of front drag hook part and the shank Some bails.

Novel adjustable exposure of surgical field drag hook as described above, the front end monodactyle of the drag hook part or the length of multijaw structure Degree is 5-10mm.

Novel adjustable exposure of surgical field drag hook as described above, the handle of the tail portion and rear traction element of front drag hook part Portion junction is nature radian intermediate form.

The pawl number of novel adjustable exposure of surgical field drag hook as described above, front drag hook part is 1-5 pawls.

The pawl number of novel adjustable exposure of surgical field drag hook as described above, front drag hook part is 3 pawls.

The advantages of the utility model, is as follows：

(1) self-retractor greatly saves human resources.The diseases such as thyroid adenoma, nodular goiter appear on the stage doctor can Reduce to two people (traditional drag hook need three to four people), the diseases such as thyroid cancer, hyperthyroidism, retrosternal thyroid doctor that appears on the stage reduces to three people (traditional drag hook needs four people).

(2) appear satisfied, drawing stabilization in art, extremely can also easily appear on such as thyroid gland larger to difficulty, and And it can adjust at any time as needed.

(3) cheap, every piece of drag hook cost is not higher than 50 yuan, if yield increase will be more cheap, and can make repeatedly It is easy to spread with (only needing update rubber band).

(4) body portion is changed to overall structure, only end retains 5-10mm claw-like structures, retains the natural radian of drag hook, more Add the needs for adapting to different depth level drawings, and greatly reduces to the subcutaneous extruding of skin；

(5) it is suitble to all kinds of sterilization methods, it can Reusability.

Description of the drawings

Fig. 1 is the dimensional structure diagram of the utility model.

Specific implementation mode

The concrete structure of the utility model is shown in Figure 1.

Novel adjustable exposure of surgical field drag hook, including front drag hook part 1 and rear traction element；Front drag hook part 1： Stainless steel structure, sturdy and durable, using two kinds of materials of common stainless steel and matt stainless steel, matt material can effectively prevent performing the operation Light reflection is dazzling but price is slightly higher；5~10cm of entire length is differed, and is suitable for different parts, differential tension requirement；It is described Front drag hook part 1 is that back segment is in plane, and the arc-shaped plates of leading portion are monodactyle at the front end of the arch section of plates Or multijaw structure 5, these pawl laid out in parallel, in the identical radian for adapting to different depth level drawings and needing, pawl point is passivity Structure.Claw designs for multijaw, including 1~5 pawl, and the most frequently used at present is 3 pawls, can effectively pull, be not easy to slip；Pawl point passivity, Inorganization is damaged.The predominantly body arrangements of claw improvement described in the utility model, former drag hook body portion are still prolonging for multijaw structure It stretches, it is apparent to find that the design squeezes skin subcutaneous tissue in actual use, especially may cause group after the long period draws It knits compression extravasated blood, ecchymosis is subcutaneously presented, influence wound healing and beauty.Therefore body portion is changed to overall structure, only end retains 5-10mm claw-like structures, the needs and greatly which retains the natural radian of drag hook, more adapts to different depth levels drawing Reduce to the subcutaneous extruding of skin.Tail portion is ring-type, facilitates the fixed attachment of traction element.

The rear traction element includes the shank with the angled connection of plane where the tail portion of front drag hook part 1 2 and the shank 2 the bail 3 that is equipped with of tail portion.

Rear traction element：General Purpose Rubber rubber band 4 is fixed on slip-knot in drag hook tail portion bail 3, easy to operate, valence Lattice are cheap, common sterilization method can be used, after a period of use rubber band aging, should replace at any time, replacement process it is very easy； It is fixed on aseptic towel behind the position to satisfaction of adjustment drag hook, with common haemostatic clamp clamp rubber band when use, passes through and change clamp The Tensity size of rubber band, direction can easily adjust the drawing dynamics, the depth that appear, without assistant, it is sustainable firmly, stablize, nothing Artificial hand shaking equivalent risk.

The utility model is performed the operation suitable for any superficial, including the lymph node biopsies such as superficial tumor excision, neck groin, Muscle biospy, and it is widely used in the partial surgical of Head and neck tumour, orthopaedics, neurosurgery, such as the parotid gland, salivary gland, scalp tumor, neck Vertebra, backbone, radiculopathy etc. are ready for promoting to other field.
