Abstract

The utility model relates to a multi-function adjustable abdomen-cut-open device, belonging to the technical field of medical equipment production. The utility model has the structure of a reversed scissor-type double-arm trefoil semiautomatic retractor, composed of vertical steering double arms and trefoil which can freely regulate integral drawing angle and flexible change hooks. The opening angle of the double arms is controlled by a bidirectional self-locking latch. The utility model has the advantages of novel, special, and simple structure, practical use, flexible drawing angle for incision, clear operative field, easy operation, and application to the closure of intrathoracic incision.

Description

Multi-functional adjustable abdomen opening device

This utility model belongs to medical surgical instrument and makes the field.

Background technology of the present utility model is: suspension abdominal cavity retractor: be Surgical Instruments No.6 Factory, Shanghai's a kind of mobile jib slide fastener suspention newly developed, be suitable for the abdominal retractor of operations such as what epigastrium liver and gall, the wild exposure of art still can, but mobile jib causes obstacle to the patient, the inconvenience operation technique is applied limited.

Purpose of design of the present utility model is: avoids weak point of the prior art, designs and a kind ofly can arbitrarily angledly retract otch, but accessible to the art open country, be beneficial to operation, the also multi-functional adjustable abdomen opening device of closed-chest otch.

Design of the present utility model: the present invention is directed to the wild exposure problem of art in the surgery operation of each minute in the present Clinical Surgery field, a kind of multifunctional adjustable retractor that designs according to the statistics of a large amount of all kinds of surgical incisions.The otch that is suitable for any operation of what retracts, and art is wild to be exposed.As department of obstetrics and gynecology, the outer operation operation etc. of oozing of epigastrium hepatobiliary surgery, gastrointestinal procedures, hypogastric region and the pelvic cavity of thoracic surgery, department of general surgery, the thoracic cavity closure when also available what closes breast.Can arbitrarily angledly retract otch, accessible to the art open country, sharp what operation.But also closed-chest otch.On design, the design is the semi-automatic retractor of inverted scissor type both arms SANYE.Can adjust the tractive angle arbitrarily and the drag hook that can change is flexibly formed by two arms that have Height-adjusting device and SANYE.Its angle that opens arms can be controlled by the bidirectional self-locking kayser.Its organization plan: a kind of multi-functional adjustable abdomen opening device, arm (1) and arm (2) constitute the inverted scissor type arm structure, middle arm (3) is positioned at the hinged place of arm (1) and arm (2) and is connected with clamp nut (10) by screw (12), abdominal spatula (4) is connected with the end of middle arm (3) by screw (11) and clamp nut (9), Height-adjusting device (7) lays respectively on the arm of arm (1) and arm (2) by trip bolt (8), drag hook (5) lays respectively at the arm end of arm (1) and arm (2), arc pinboard (17) by screw (6), latch (13), latch plate (14), shank is cut in the manual control that nut (16) and screw (15) constitute kayser plug mechanism and be positioned at arm (2).The left part of arm (1) and arm (2) articulated section is the U font, right part is that handle structure is cut in manual control.In the end of arm (3) be middle arm drag hook and be epsilon-type structure, arm and have strip slip through hole (18) and can slide along screw (12).Have strip slip through hole (19) on the abdominal spatula (4) and can slide along screw (11).Drag hook (15) is the concave shape structure and can rotates around screw (6).The arc pinboard has several latch hole on (17).Have hole (20) on the left part of arm (1) and arm (2).

This utility model is compared with background technology; The one, retract automatically, do not take manpower.Select corresponding drag hook to get final product the arbitrarily angled otch that retracts according to operative incision, appear the art open country; The 2nd, purposes is wide.Be suitable for retracting of the various operative incisions of what.As epigastrium liver, gallbladder, pancreas, spleen, stomach, duodenal operation in thoracic surgery thoracotomy, the department of general surgery, middle lower abdomen intestinal surgery, the obstetrics and gynecology operation of pelvic cavity.And operations such as the kidneys of Urology Surgery, bladder, prostate, and owing to have bidirectional self-locking function, the chest incision closure of available what thoracotomy; The 3rd, it is abundant that the art open country appears.This retractor can be according to the arbitrarily angled otch that retracts of requirements of operation, but and the flexible two arm drag hook degree of depth, regulate the angle of the 3rd drag hook, the irrelevant abdominal visceral browser of angle, the degree of depth, isolation and operation of abdominal spatula simultaneously, fully appear the art open country, in order to patient's operation, apparatus is accessible to the patient; Four are to use conveniently, and cost is lower.This apparatus is that common stainless steel is made, and sterilization is with general apparatus, comprehensive utilization value height.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

1 pair of this utility model is done with narration in conjunction with the accompanying drawings

1, arm (1) and arm (2) constitute the inverted scissor type arm structure, in arm (3) be positioned at arm (1) and arm (2) the hinged place and and arm (1), that arm (2) is all a screw (12) is hinged, in the end of arm (3) be middle arm drag hook and be epsilon-type structure, arm has strip slip through hole (18), strip slip through hole (18) is enclosed within that screw (12) is gone up and slidably, clamp nut (10) is screwed on the screw (12), and purpose is as required middle arm (3) to be located; Have strip slip through hole (19) on the abdominal spatula (4) and be enclosed within that the screw (11) that is arranged on arm (3) end is gone up and slidably, clamp nut (9) is screwed on the screw (11), purpose is as required abdominal spatula (4) to be located; Height-adjusting device (7) is installed in respectively on the arm of arm (1) and arm (2) by trip bolt (8), and purpose is the degree of depth that can regulate drag hook (5) arbitrarily; Have on the arc pinboard (17) several latch hole and and mortise lock (13), latch plate (14), nut (16), screw (15) constitute kayser plug structure, shank is cut in the manual control that its arc pinboard (17) is fixed on arm (1), it is affixed that shank front, front end and latch (13) are cut in the manual control that latch plate (14) tail end is fixed on arm (2) by screw (15), the back side on the shank is cut in the manual control that nut (16) is screwed in arm (2), and purpose is along the open angle of arc plate (17) further location under the kayser effect of mortise lock (13) with arm (2).
