Abstract

The utility model relates to a pull-scraping type semicircular concave-faced mammary gland exposure retractor, which belongs to the field of medical equipment and comprises a handle and a pair of circular arc-shaped concave retractors, wherein the concave retractors fixed to one end of the handle project out of a plane of the handle. The pull-scraping type semicircular concave-faced mammary gland exposure retractor is characterized in that a boss projecting out of the plane of the handle is further fixed to the other end of the handle, the projection direction of the boss is opposite to those of the concave retractors, and chamfered angles are arranged on the bottom surfaces of the concave retractors. The mammary gland exposure retractor has the advantages of reasonable structural design, capability of meeting the requirements of incisal edges, precise resection, convenience and reliable utilization, capability of sufficiently exposing mammary gland tissues in a surgery, and great help for diagnosis and treatment of early-stage breast cancer.

Description

Draw and scrape formula semicircle concave surface mammary gland exposure drag hook

Technical field

This utility model relates to a kind of drag hook, and particularly a kind of drawing scraped formula semicircle concave surface mammary gland exposure drag hook, and the abundant exposure of mammary gland tissue belonged to medical instruments field when it mainly was applicable to untouchable breast lesion excision.

Background technology

In the early diagnosis and therapy field of medical circle breast carcinoma, there is a kind of pathological phenomenon to be called untouchable breast lesion.It mainly comprises calcification point two classes that little lump that mammary gland is untouchable and cluster distribute.Medical circle thinks that these two kinds of focuses are that breast carcinoma of early stage is in clinical performance.Therefore need carry out the living tissue pathologic finding to it, be optimum or pernicious with clear and definite focus, whether needs further processing.In the prior art, mainly contain two kinds of biopsy methods: a kind of is to utilize instrument through the skin aspiration biopsy, but the defective of the method is can not complete excision focus; Another kind is the biopsy of direct surgical resection focus, and its defective is that the specimen excision is irregular in the operation, in case be found to be malignant tumor, in the time of need appending the excision mammary gland tissue, the edge of focus is difficult to determine.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design, incisxal edge meet the requirements, easy to use drawing scraped formula semicircle concave surface mammary gland and exposed drag hook and provide.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this draws scrapes formula semicircle concave surface mammary gland and exposes drag hook and comprise handle and recessed hook, this recessed hook is a circular arc, it is fixed on an end of handle, and this recessed hook protrudes the plane of handle, it is characterized in that: the other end at described handle also is fixed with the planar finger holder of protrusion handle, and this refers to that the protrusion direction that holds in the palm is opposite with the protrusion direction of recessed hook; Make this utility model convenient in use reliable; There is chamfering the bottom surface of described recessed hook; Described drag hook is a pair of; The abundant exposure of mammary gland tissue in convenient operation during use.

As preferably, the interior diameter of a pair of recessed hook described in the utility model is 1.5-2.5cm, to adapt to the excision of untouchable breast lesion.

As preferably, the hook of recessed hook described in the utility model is 1.5-2.5cm deeply, to adapt to the excision of untouchable breast lesion.

As preferably, the length of handle described in the utility model is 10-15cm, with the carrying out of convenient operation.

As preferably, the height of finger holder described in the utility model is 1.5-2.5cm.

This utility model compared with prior art has following positive effect: reasonable in design, excision are precisely; Simultaneously, easy to use and reliable, the mammary gland tissue in the operation is fully exposed, the Clinics and Practices of breast carcinoma of early stage there is great help.

Description of drawings

Fig. 1 refers to the structural representation front view that holds in the palm for this utility model band.

Fig. 2 refers to hold in the palm structural representation axonometric chart after removing for this utility model.

The specific embodiment

Referring to Fig. 1-Fig. 2, this utility model is mainly by handle 1, recessed hook 2 with refer to hold in the palm 3 to form; This utility model uses in pairs.

In the present embodiment, recessed hook 2 is a circular arc, and it is fixed on an end of handle 1, and the plane of these recessed hook 2 protrusion handles 1, so that the mammary gland tissue in the operation is fully exposed; The other end at described handle 1 also is fixed with the 1 planar finger holder 3 of protrusion handle, and with convenient operation, otherwise doctor's hands is very easily run into patient's skin, hinders the carrying out of operation; This refers to hold in the palm 3 protrusion direction opposite with the protrusion direction of recessed hook 2; There is chamfering 21 bottom surface of described recessed hook 2, can push fatty tissue easily aside when operation, exposes the mammary gland tissue surface; Handle 1 is with recessed hook 2 and refer to that holder 3 is fixing by welding respectively.

In the present embodiment, the interior diameter ￠ of a pair of recessed hook 2 is 2.0cm; The dark H1 of the hook of recessed hook 2 is 2.0cm; The length L of handle 1 is 12cm; The height H 2 that refers to holder 3 is 2.0cm.

Handle of the present utility model 1 and refer to that holder 3 can be with rustless steel or plastic production, recessed hook 2 the most handy insulating plastic productions, so that skin histology is not burnt during operation by electric knife, wound healing is better, cicatrix is littler.

This description said " there is chamfering 21 bottom surface of recessed hook 2 " is meant: at the whole arc end of recessed hook 2 away from handle 1, its surface is not a thickness, but a cutting edge is arranged, similar chamfering; It can push fatty tissue easily aside, exposes the mammary gland tissue surface.

This utility model in use, can conveniently manifest the mammary gland of lesions position by the chamfering 21 of a pair of recessed hook 2 bottom surfaces, precisely downcut the column type specimen that contains lesions position with electric knife then, use 12 point location methods again and can append localized resection, the safe incisxal edge of 0.5～1.0cm is arranged on every side to guarantee focus.

This utility model will produce far-reaching influence to the Clinics and Practices of breast carcinoma of early stage.

Above content described in this description only is to the explanation of this utility model structure example.The simple deformation or the combination of every this utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
