Description

Automatic cerebral retractor bedside fixed mount

Technical field:

This utility model relates to a kind of Automatic cerebral retractor bedside fixed mount, is used for fixedly Automatic cerebral retractor of clinical medicine neurosurgery specialty operation.

Background technology:

Along with microneurosurgery work carry out and use popularize, snakelike Automatic cerebral retractor has been neurosurgery operating theater instruments commonly used.But the present fixture of the snakelike Automatic cerebral retractor that uses exists fixing unstable, a bad difficult problem such as fix, be difficult to fix, can not fix always, has influenced the perform the operation use of snakelike Automatic cerebral retractor of brain deep.

Summary of the invention:

The purpose of this utility model provides a kind of Automatic cerebral retractor bedside fixed mount, solve snakelike Automatic cerebral retractor fixingly unstable, bad fix, be difficult to fix, can not a fixed difficult problem.

The purpose of this utility model realizes as follows: it relates to pole, the lower end of pole is vertical with the upper end, the pole lower end connects the strut fixation device, the pole upper end connects universal ball joint, universal ball joint top self-retaining retractor fixed pedestal, be connected and fixed the pressing plate of Automatic cerebral retractor above the retractor fixed pedestal by bolt, by pressing plate Automatic cerebral retractor is fixed on the retractor fixed pedestal, this can be fixed on the sick bed limit by the strut fixation device, open the cranium difference according to left and right sides, can be fixed on the corresponding left and right sides of bedside, and can regulate pole position in bed, the height of pole, the angle of pole can further be adjusted the angle of Automatic cerebral retractor by universal ball joint.According to the operation needs, satisfy multiple different operation needs such as dorsal position, lateral position, ventricumbent position, cerebral hemisphere operation and back cranium nest operation.Can install at any time before the operation and in the operation, use the headstock and head circle all can use.Do not need to be fixed on out on the skull window, especially can satisfy the needs of keyhole surgery.

The strut fixation device is by pedestal, slide, gland, apical ring, fastening bolt constitutes, pedestal has grasp opening, be used to be stuck in the sick bed limit, hollow slide rear portion has boss to be in the pedestal inner groove, making slide rotate but to limit it relative to pedestal moves forward, draw simple front portion that fastening bolt is set, the apical ring ring body partly is attached in the pedestal outer groove, apical ring has two paws to pass the pedestal notch to stretch out in the pedestal grasp opening, apical ring can be moved to the grasp opening direction, but can not rotate relative to pedestal, gland is enclosed within on the slide cylindrical, be useful on the circular hole that penetrates pole on the cylindrical wall of gland, the gland rear end leans on the end face of apical ring, and both faying faces are serrated face.During use, gland circular hole and slide core are passed in the pole bottom, adjust the angle of pole, at this moment gland rotates certain position with slide relative to pedestal, inwardly the turn fastening bolt leans on pole its end, because slide is by axial limiting, fastening bolt heads on pole, pole drives gland and draws close to pedestal, and pedestal end face compressing apical ring stretches into the paw of apical ring in the pedestal grasp opening, when grasp opening is buckled on the bedside, the apical ring paw clamps bedside, screw fastening bolt after, this strut fixation device is simultaneously and bedside and strut fixation, gland and apical ring are because the effect of serrated face, do not relatively rotate and can not produce, because apical ring and pedestal circumferentially are fixed, like this, gland is circumferentially fixed, and pole can circumferentially not swung.

Universal ball joint is made of lower base, upper pedestal, spheroid and heading bolt, lower base and pole upper end are fixing, lower base and upper pedestal are by being threaded togather, they form the inner chamber that can hold spheroid, in this inner chamber spheroid are housed, and opening is arranged above the upper pedestal, there is connecting rod to be connected by this opening with spheroid, the other end of connecting rod connects the retractor fixed pedestal, device heading bolt on the lower base, and the leading section of heading bolt withstands on the spheroid arc surface.After adjusting retractor fixed pedestal position, screw the heading bolt spheroid is fixed, thereby the retractor fixed pedestal is fixed.

This utility model is by the strut fixation device, and the height of the whole fixed mount of scalable makes fixed mount pole put the desired position of operation.By the angle of universal ball joint scalable retractor fixed pedestal, make it put the desired ideal angle of operation.The advantage that it has: (1) can satisfy the needs of keyhole surgery; (2) satisfy the needs that back cranium nest is performed the operation; (3) can make things convenient for installation at any time before the operation and in the operation; All can use when (4) using the headstock, head rest and head circle; (5) operation and curtain are united out multiple different operation needs such as cranium up and down down to satisfy on dorsal position, lateral position, ventricumbent position, the curtain operation, curtain.

Description of drawings:

Fig. 1 is the structural representation of this utility model Automatic cerebral retractor bedside fixed mount.

Fig. 2 be among Fig. 1 A-A to view.

The specific embodiment:

With reference to Fig. 1, Fig. 2, this fixed mount also equally has individual pole 8 with other fixed mount, the lower end of pole 8 is vertical with the upper end, pole 8 lower ends connect the strut fixation device, the strut fixation device is used for whole fixed mount and sick bed bedside 1 fixing, pole 8 upper ends connect universal ball joint, universal ball joint top self-retaining retractor fixed pedestal 15, the retractor fixed pedestal 15 top pressing plates 17 that are connected and fixed Automatic cerebral retractor 16 by bolt 18.The strut fixation device is made of pedestal 2, slide 5, gland 4, apical ring 3, and pedestal 2 has grasp opening, and grasp opening is stuck on the bedside 1 in the time of fixedly; Slide 5 has groove, its rear portion has boss to be in pedestal 2 inner grooves, slide 5 front portions are provided with fastening bolt 6, its handle of turn 7 is equipped with in fastening bolt 6 ends, apical ring 3 ring bodies partly are attached in pedestal 2 outer grooves, apical ring 3 has two paws to pass pedestal 2 notches to stretch out in the grasp opening of pedestal 2, gland 4 is enclosed within on slide 5 cylindricals, radially be useful on the circular hole that penetrates pole 8 on the circumferential wall of gland 4, this circular hole is passed in the bottom of pole 8 in the time of fixedly, gland 4 rear ends lean on the end face of apical ring 3, and both faying faces are serrated face, frictional force during with relatively rotating between increasing.Universal ball joint is made of lower base 11, upper pedestal 13, spheroid 12 and heading bolt 9, lower base 11 is fixed with pole 8 upper ends, lower base 11 and upper pedestal 13 are by being threaded togather, they form the inner chamber that can hold spheroid, spheroid 12 is housed in this inner chamber, above the upper pedestal 13 opening is arranged, there is connecting rod 14 to be connected by this opening with spheroid 12, the other end of connecting rod 14 connects retractor fixed pedestal 15, device heading bolt 9 on the lower base 11, the leading section of heading bolt 9 withstands on spheroid 12 arc surfaces.Heading bolt 9 outer ends connect handle 10.
