Description

Abdomenal operation ring type retractor

The auxiliary implement of using when this utility model relates to a kind of surgical operation, particularly a kind of abdominal operation annular pull device.

At present, the patient is implemented abdominal part operate on when operation, generally all be to use the abdominal part self-retaining retractor.This utensil can only be opened the abdominal cavity otch from two or three direction tractives symmetrically, because its structure is unreasonable, limit the operator visual field greatly and exposed angle (or direction), and deep tissue tractives such as abdominal viscera can not be opened, for enlarging the exposure surgical field of view, appear abdominal viscera and deep tissue, must allow the assistant add again and use the deep retractor tractive, this has just increased assistant's labor intensity greatly, and is difficult to the operator operator accurate surgical field of view is provided enduringly.

The purpose of this utility model is to disclose a kind of a plurality of angles or direction tractive can selected for use arbitrarily to open operative incision, and can provide accurately, stablize for operation operator person, broad surgical field of view, can expose the novel abdominal operation tractor of abdominal viscera and deep tissue on demand.

Utilize accompanying drawing that technical conceive of the present utility model and specific embodiments are comprehensively described in detail below:

Fig. 1 is a population structure sketch map of the present utility model.

This tractor also comprises drag hook (1) and fixed mount, different is, its fixed mount is by a flat circle (2) and a cross bar, a montant (5) and assemble in order to the cross coupling block (6) of clamping cross bar and montant (5), and cross bar is to be made of in the core hole of a loop bar (4) a core bar (3) device, offering a grab groove on the front end position of core bar (3), also offering bayonet slot one on loop bar (4) front port, flat circle (2) is flat in the grab groove of core bar (3), make grab groove dogging on core bar (3) the front end position the inner ring wall of flat circle (2), bayonet slot clip on loop bar (4) front port the collar wall of flat circle (2), the rearward end of core bar (3) is one section threaded rod, and is fitted with one and tightens up nut (7).The front end face that tightens up nut (7) is being replaced the rear end face of loop bar (4), screw tighten up nut (7) with core bar (3) towards post-tensioning, flat circle (2) just can be put down forward and be stretched on the front end position that is packed in cross bar.Cross bar and montant (5) are headed on to intert separately to be packed in by clamping lever (8) folder that is being equipped with in the screw on cross connection piece (6) body respectively and are horizontal on cross coupling block (6) body, in the through hole that perpendicular both direction is being offered, whole fixed mount is that the bottom with montant (5) is packed on the holding frame set on the operating-table, adjust the height and position of cross coupling block (6) on montant (5) and the direction that stretches of cross bar, and it is tight with clamping lever (8) top clamping, adjust the position that tightens up cross bar again, make flat circle (2) just flat stretch cover to be about to the patient operative site above, after forming operative incision, on demand promptly, more than on using two or two, offer the drag hook (1) of direct through groove on the mid-plane, draw back operative incision at predetermined direction position hook respectively, clamping bolt (9) clamping that reuse is placed through in the circular groove groove of offering in flat circle (2) plane is fastened on the flat circle (2).For making things convenient for the user operation, tighten up the nut of nut (7) and clamping bolt (9), preferably all adopt wing nut.

Because the intermediary circular groove groove in flat circle (2) plane almost is that ring is offered, so in use, can a plurality of directions and angle device drag hook (1), with the tractive operative incision.Simultaneously, also offer direct through groove on drag hook (1) mid-plane, so can arbitrarily set up size and the shape that dragline is opened operative incision on demand; Moreover, after fixed mount and drag hook (1) are fastened, be difficult for displacement, thereby for operator provides accurate, a stable surgical field of view, and surgical field of view is also many than existing tractor spaciousness, use in reality, can be equipped with the length of many cover gib heads and the drag hook (1) that size has nothing in common with each other, select for use according to the hands mouth otch size shape and the operative site depth during for operation.This novel tractor not only is suitable for general surgery to be used, and is applicable to gynecological, urology department operation.
