Abstract
The utility model relates to an automatic draw hook for the appendectomy, belonging to the improvement of a medical appliance. The draw hook for the appendix operation at present impedes the field of vision when an operator and an assistant respectively hold draw hooks by one hand to carry out the operation, particularly when the appendectomy and the purse string suture are carried out, and nurses need to help hold the draw hooks. When the adhesive appendix ablation is carried out, the draw hook for the appendix operation at present has the disadvantages of insufficient length and width and inconvenient operation. The device is an automatic draw hook used for the overall process of the appendix operation, and therefore, the history of holding the draw hook by hand in the operation is completed. When the device is flexibly operated, the incisions with different depths and widths in various operations can be automatically pulled apart by means of the rotation of the draw hook plate toward different angles, and therefore, operators can vacate both hands to more conveniently carry out the operation. One hook with multiple uses replaces the original three sets of draw hooks which have the defect of complexity.
Description
The invention belongs to the improvement design of medical apparatus and instruments.
At present surgeon is made the existing vermiform appendix drag hook that Appendectomy is used, be exactly patient and assistant each operate with a hand-held drag hook, especially when doing appendectomy and during purse string suture, the overslaugh visual field also will ask the nurse to assist drag hook, it is not enough to feel more staff.When meeting the appendectomy of deep adhesion, this hook length and width deficiency, very inconvenient with three cover drag hook complete operations.
The objective of the invention is to design a kind of, be used for the self-retractor of Appendectomy overall process, thereby finish the west operating theater instruments, the history of hand-held drag hook in the art.Patients can utilize the both hands of oneself operation that undergos surgery fully, have solved existing drag hook width and the insufficient shortcoming of the degree of depth, appear the visual field better, and a hook multipotency replaces the without hesitation numerous of former usefulness three cover drag hooks simultaneously.
The present invention is on the basis of former mastoid process spreading forceps, changes the tip clamp part structure, overlaps the adnexa that is adapted to characteristics of the present invention by having adorned one.When surgical incision skin and subcutaneous tissue, right hand-hold pincers handle ring (1) is put into otch to (the peaceful drag hook sheet of right-angle retractor sheet (2) buckle drag hook sheet (3) (4) group that is riveted together), clutch the bright ring of hands, by central screw (5), the drag hook sheet group (2,3,4) that makes jaw (6) drive rivet (1) riveted joint is opened simultaneously, retract subcutaneous tissue, appear otch, by spring leaf (8) and arc-shaped rack (9) fixedly corresponding width undergo surgery.When separating the flesh layer, in order to adapt to the degree of depth of flesh layer, drag hook (3.4) is opened, rotate 180 degree-(promptly having prolonged drag hook length) around rivet (10).Utilize the curved forward bent angle of drag hook hook sheet (3) of band, can thoroughly hook obliquus internus abdominis m. separates outside peritoneum, after cutting peritoneum, for increasing the width of drag hook, hook sheet (3.4) is 90 degree with drag hook sheet (2) respectively to be opened, or any required orientation, so that stop intestinal tube and omentum majus bulging, promptly be equivalent to prolong the length and the degree of depth of surgery tractor.Behind appendectomy, press arc-shaped rack under the elastic force of spring leaf, jaw is closed automatically, takes out drag hook and gets final product.
Use the present invention can make the patient, apply in a flexible way in operation, owing to pass through the rotation of drag hook sheet different angles, also can be used for multiple operation, the otch of different depth and width draws back.Because reed and arc-shaped rack have been fixed open otch to appear the visual field, can make patients vacate both hands and undergo surgery more easily.This invention can be used for the Appendectomy overall process, can the many usefulness of a hook, replace without hesitation numerous that existing Appendectomy need be with three cover drag hooks (skin retractor, vermiform appendix drag hook, right angle deep-draw hook).Make the model that varies in size and can be used for multiple operation.
